Subject: [PATCH 001/176] fix(gallery): add auth check to /api/image/sharpen
 endpoint (#2761)

Every other image-processing endpoint (denoise, upscale, remove-bg,
enhance-face, inpaint, harmonize) calls require_privilege(request,
"can_generate_images"). The sharpen endpoint was missing this check,
allowing unauthenticated users to trigger CPU-intensive image processing.

Subject: [PATCH 002/176] fix(document): add 404 guard to version list/get
 endpoints (#2762)

list_versions and get_version used a soft 'if doc:' guard that skipped
ownership verification when the Document row was missing (e.g. after
hard delete). Orphaned DocumentVersion rows would be returned to any
caller without auth. Now raises 404 when the parent document is gone,
matching the pattern already used in restore_version.

Subject: [PATCH 003/176] fix(tasks): validate then_task_id belongs to same
 owner on create/update (#2764)

then_task_id was stored without checking the target task's owner. A user
could chain their task to execute any other user's task on success via the
scheduler's _run_chained path. Now verifies the target task exists and
belongs to the requesting user before storing.

Subject: [PATCH 004/176] fix(caldav): include owner in calendar ID hash to
 prevent PK collision (#2765)

_stable_cal_id hashed only the remote URL, producing the same calendar
ID for all users syncing the same CalDAV endpoint. The second user would
get an IntegrityError on the primary key. Now includes owner in the
hash so each user gets a distinct calendar row.

Subject: [PATCH 006/176] fix(security): close DNS-rebinding hole on
 diffusion_server (wildcard CORS + missing Host check) (#347)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(security): close DNS-rebinding hole on diffusion_server

scripts/diffusion_server.py used to ship `allow_origins=["*"]` with the
default `--host=127.0.0.1` bind. Combined, that left the OpenAI-compatible
image API reachable from any browser tab via DNS-rebinding: an attacker page
resolves its own domain to 127.0.0.1 mid-fetch, the browser forwards the
request to the loopback server, the server processes it (no Host check), and
the wildcard CORS reply lets the attacker page read the result + drive the
GPU. CWE-346 + CWE-942 + CWE-352 (DNS-rebinding bridge).

Fix:
  - Drop the wildcard CORS at module load (default-deny).
  - Install `TrustedHostMiddleware` with a loopback allowlist so DNS-rebound
    requests are rejected by the middleware before any route runs.
  - Add additive `--allowed-host` / `--allowed-origin` CLI flags so operators
    who need browser access on a specific origin can opt in explicitly without
    re-introducing the wildcard.

Tests: tests/test_diffusion_server_security.py (9 cases) pin the allowlist
helpers, the default-deny CORS behavior, and the live middleware paths via
Starlette's TestClient.

Detected by Aeon + semgrep + manual review.
Severity: medium.
CWE-346 / CWE-942 / CWE-352.

* test(diffusion-server): drive ASGI app via httpx, not TestClient portal

The TrustedHost/CORS integration tests used `with TestClient(app) as
client:`, whose context-manager form spins up an anyio blocking portal to
run the app lifespan. Under the repo's pytest setup (anyio plugin active, a
stray asyncio_mode option, no pytest-asyncio) that portal deadlocks —
`test_trusted_host_middleware_rejects_attacker_host` hung indefinitely in
review before emitting any assertion output.

Replace the TestClient usage with a tiny _asgi_get() helper that drives the
ASGI app over httpx.ASGITransport on a fresh event loop (asyncio.run). No
portal, no lifespan, no dependency on the host project's async test plugins.
Host is taken from the request URL so TrustedHostMiddleware sees the exact
hostname under test; Origin goes through headers. Assertions are unchanged.

Focused test now passes in 0.12s; full file 9 passed.

Subject: [PATCH 008/176] fix(webhooks): redact IPv6 addresses in sanitized
 error messages (#3038)

* fix(webhooks): redact IPv6 addresses in sanitized error messages

sanitize_error() only stripped IPv4 literals, so a failed webhook
delivery to an internal IPv6 host (::1, fe80::/fc00:: ...) leaked the
address into Webhook.last_error, which is surfaced in the UI. The module
already treats internal IPv6 as sensitive (see _PRIVATE_NETWORKS and
src/url_safety.py); the scrubber just didn't keep up.

Add an IPv6 redaction pass covering bracketed, full 8-group, and
::-compressed forms. The pattern is scoped to leave clock times
("12:34:56"), MAC addresses, and C++ "::" tokens untouched, and the
::-branch uses a lookahead over a flat character class so there is no
nested quantifier to backtrack on (no ReDoS on long colon/hex runs).

Adds tests/test_webhook_sanitize_error_ipv6.py.

* webhook: validate IPv6 candidates with ipaddress, not a regex grammar

Per review on #3038: instead of hand-rolling the IPv6 grammar in a regex
(brittle, and easy to over-match colon-heavy text), use a loose regex to
find candidate tokens and let ipaddress.ip_address() decide. Only tokens
it parses as IPv6 are redacted, so the false-positive guards (clock times,
MACs, "std::vector") now come from the stdlib instead of a custom pattern.

This also covers cases the old pattern missed -- zone ids (fe80::1%eth0)
and IPv4-mapped addresses -- and no longer partially mangles invalid
colon strings (a 9-group token is preserved whole rather than losing its
first 8 groups). The bracketed branch is a single greedy class with no
X*:X* backtracking; verified ~1ms on 40k-char adversarial input.

Extends the test file with zone-id, IPv4-mapped, and invalid-token cases.

* webhook: redact bracketed/scoped/IPv4-mapped IPv6 as one unit

Review on #3038 found a few IP forms left partially redacted or malformed
by sanitize_error():

  [fe80::1%eth0]:8080        -> [[redacted]]:8080
  [::ffff:192.168.0.1]:8080  -> [[redacted][redacted]]:8080
  ::ffff:192.168.0.1         -> [redacted][redacted]

Two causes: the bracketed branch's character class dropped zone ids, so
scoped addresses fell through to the bare branch and left the brackets and
port behind; and the IPv4 pass ran first, stripping the embedded v4 of an
IPv4-mapped address so the v6 pass then redacted the "::ffff:" remnant
separately.

Fix:
- run the IP-candidate pass before the IPv4 pass, so IPv4-mapped forms are
  matched and redacted whole
- match the full bracketed authority ([...] + optional %zone + :port) as a
  single token, and redact a v4-or-v6 literal inside [ ] as one [redacted]
- extend the bare branch with a bounded (exactly-3) dotted-quad tail for
  IPv4-mapped forms; exactly-3 so it can't swallow a partial suffix and
  accidentally preserve an otherwise-valid address

Each form now collapses to a single [redacted]; the candidate finder stays
linear (~1.3ms on 40k-char adversarial input). Adds regression tests for
the three reported forms and keeps the timestamp/MAC/std::vector coverage.

Subject: [PATCH 009/176] fix(security): add HSTS and Permissions-Policy to
 SecurityHeadersMiddleware (#3081)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(security): add HSTS and Permissions-Policy headers to SecurityHeadersMiddleware

Strict-Transport-Security is sent only when the connection is HTTPS
(detected via request.url.scheme or X-Forwarded-Proto: https), so
plain-HTTP dev deployments behind a reverse proxy are unaffected.

Permissions-Policy disables camera, microphone, and geolocation APIs
unconditionally — Odysseus does not use them, and this prevents a
successful XSS from requesting browser-native sensor access.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(security): scope Permissions-Policy microphone directive to same-origin

Reviewers on PR #3081 (alteixeira20, NubsCarson) flagged that
microphone=() blocks mic access for same-origin (self) too, breaking
Odysseus's own voice/STT flow (getUserMedia({audio: true}) in
static/js/voiceRecorder.js). Scope it to microphone=(self) so
third-party origins stay locked out while the app's own UI keeps mic
access; camera and geolocation remain fully disabled as unused.

Adds focused middleware tests covering HSTS scoping (HTTPS direct,
X-Forwarded-Proto, absent on plain HTTP) and the Permissions-Policy
same-origin microphone contract.

Subject: [PATCH 010/176] fix(caldav): disable redirects on the sync/write-back
 DAVClient (SSRF) (#2663)

validate_caldav_url resolves and vets the initial host, but caldav's
niquests session follows 3xx redirects by default, so a validated public
URL can be redirected at request time to loopback/link-local/private
space, re-opening the SSRF the host check closes. The existing redirect
guard only covered the settings test-connection path.

Add a shared _build_dav_client helper that pins the session to zero
redirects (any 3xx then raises instead of silently following an
attacker-chosen Location), and route both the pull (_sync_blocking) and
write-back (_writeback_blocking) paths through it. Mirrors the
follow_redirects=False already used on the test-connection path.

Tests exercise the real DAVClient request path (a 302 toward an internal
host is refused, the sink is never contacted; the PROPFIND is asserted to
reach the public server first so the check can't pass vacuously), confirm
the helper disables redirects on the installed client, guard against a
raw DAVClient creeping back in, cover mixed public/internal DNS results
in both orderings, and add the resolves-to-no-usable-records fail-closed
branch.

Subject: [PATCH 011/176] fix(email): guarantee IMAP conn.logout() on all
 exception paths (#1530)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three IMAP connection leaks were recently fixed via try/finally
(#1325, #1330, #1423). This commit applies the same pattern to the
remaining callsites that still used inline logout-only cleanup.

routes/email_helpers.py:
- _fetch_sender_thread_context: conn was uninitialized when the outer
  try/except returned early on connect failure, causing the finally
  block to crash on conn.close()/conn.logout(). Merged the two
  separate try blocks into one and added conn=None guard.
- _pre_retrieve_context: ctx_conn.logout() was inside the loop body
  with no finally, so any exception in the folder/search loop leaked
  the socket. Moved cleanup into a finally block with ctx_conn=None
  guard.

mcp_servers/email_server.py:
- _list_emails: multiple inline conn.logout() calls on early-return
  paths; exception between them leaked the socket. Wrapped in
  try/finally.
- _read_email: same pattern — four separate logout() calls replaced
  by a single finally block.
- _reply_to_email: logout() called before the error check, so an
  exception in conn.select() leaked the socket. Wrapped in
  try/finally.
- _download_attachment: same pattern as _reply_to_email.

Also adds tests/test_imap_leak_fixes.py with 9 regression tests (one
per function/failure-mode) that monkeypatch _imap_connect and assert
conn.logout() is called exactly once even when IMAP operations raise.

Subject: [PATCH 024/176] fix(cookbook): don't infer server OS from the
 browser's user-agent (#3223)

_getPlatform('local') fell back to navigator.userAgent to decide the
*server's* platform. On a Mac/Linux homeserver opened from a Windows
browser this returned 'windows', so the GGUF serve builder emitted the
Windows python-only shape (`python -m llama_cpp.server`, no
`llama-server ||` fallback). That command fails on the Unix host with
"No module named llama_cpp" even though native llama-server is installed,
and the diagnosis then misleadingly tells the user to pip-install
llama-cpp-python.

Trust the server-side hardware probe over the user-agent: a non-empty
probe backend (metal/cuda/rocm/cpu_*) means a Unix server; local Windows
instead carries platform:"windows" which already sets _envState.platform
and short-circuits. Only fall back to the browser hint when there is no
server-side signal at all. Keeps #1389/#2961's local-Windows path intact.

Fixes #3221

 - Email: use named email tools (`list_email_accounts`, `list_emails`, `read_email`, `send_email`, `reply_to_email`). Do NOT use `/api/email/accounts`; it is owner-filtered in tool context and may falsely return empty.
 - Endpoints (model providers): `/api/endpoints`, `/api/endpoints/{id}`
+- Shell: do NOT use `app_api` for `/api/shell/*`; use named command tooling instead.

 **When to prefer named tools over app_api:** if a named wrapper exists (list_email_accounts, list_emails, read_email, manage_calendar, manage_notes, list_served_models, etc.) USE IT — it has nicer output formatting and clearer schema.

Subject: [PATCH 029/176] Fix: CORS preflight 401'd by AuthMiddleware before
 CORSMiddleware (#3262)

AuthMiddleware is the outermost middleware, so a credential-less CORS preflight
(OPTIONS + Access-Control-Request-Method) was rejected with 401 before
CORSMiddleware could answer it. That blocks every cross-origin browser/WebView
client: the preflight fails, so the real request is never sent.

Let a genuine preflight through at the top of AuthMiddleware.dispatch via a pure,
unit-tested predicate (core.middleware.is_cors_preflight). Precise -- only
OPTIONS carrying Access-Control-Request-Method; a credentialed request is never
matched -- and no data access.

Subject: [PATCH 030/176] feat(tasks): assign folder='Tasks' at creation +
 backfill migration (#2834)

* feat: assign folder='Tasks' to task sessions at creation

Task sessions (LLM, action, research) now set folder='Tasks' on their
DbSession row, matching the pattern used by the Assistant folder. This
enables sidebar lens filtering without changing existing session
behaviour.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: add backfill script for task session folders

One-shot script to set folder='Tasks' on existing [Task]/[Research]
sessions that predate the folder assignment in task_scheduler.py.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: replace standalone backfill script with automatic migration

Convert scripts/backfill_task_folders.py into _migrate_backfill_task_folders()
in core/database.py, called from init_db(). The migration is idempotent (only
touches rows where folder IS NULL/empty) and runs automatically on upgrade,
so operators no longer need a manual step to tag pre-existing task sessions.

Subject: [PATCH 031/176] fix: fall back to /models probe when base URL returns
 404 (#3205)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_ping_endpoint() probes the bare base URL for non-Ollama endpoints.
OpenAI-compatible servers like llama-swap return 404 on the /v1 prefix
but 200 on /v1/models, causing endpoints to appear offline despite being
fully functional.

Add a /models fallback when the base URL returns a non-auth 4xx.
Auth failures (401/403) are treated as definitive — probing /models
would just repeat the same rejection.

Fixes #3181

Subject: [PATCH 032/176] fix(agent): don't abort legitimate tool batches as
 runaway loops (#3183)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The loop-breaker's runaway backstop counted per-tool-type call totals and
tripped whenever any tool was used >=15 times — treating 15+ DISTINCT calls
to one tool as a stuck loop. A real batch (e.g. "add these 18 birthdays to my
calendar" emits 18 distinct manage_calendar create_event calls in one round)
got flagged "calling manage_calendar over and over", the calls were discarded
(next round tools_sent=0), and 0 events were created.

Count IDENTICAL repeated call signatures instead (same tool AND args), via a
small, unit-testable _detect_runaway_call() helper. Genuine batches pass; a
model truly stuck repeating one call still trips the backstop. Adds a
regression test.

Subject: [PATCH 033/176] fix: hide Select buttons in Memory/Skills tabs when
 list is empty (#2906)

* fix: hide Select buttons in memory/skills tabs when list is empty

* fix: disable Select buttons instead of hiding them when list is empty

* fix: dim disabled Select button and remove focus outline

* fix: reload skills after single deletion so count and toolbar stay in sync

* fix: lower minimized-dock z-index from 10020 to 100 so modals stack above it

* Revert "fix: lower minimized-dock z-index from 10020 to 100 so modals stack above it"

This reverts commit 5b092ee6cd11d2a2bb79f74a9aa2a81b6b3aaa72.

Subject: [PATCH 034/176] fix(memory): record dislikes as dislikes, not
 preferences (#2435)

_fallback_memory_candidates matched both positive (prefer/like/love) and
negative (hate / do not like / don't like) sentiment verbs in one regex
alternation, then formatted every hit as "User prefers {X}.". So
"I hate cilantro" was stored as "User prefers cilantro." -- the inverse of
what the user said. These fallback facts are persisted to memory and later
re-injected into the model's context, so the inverted preference actively
misleads the assistant.

Capture the matched verb and branch on it: negatives become
"User dislikes {X}.", positives stay "User prefers {X}." (still filed under
the existing "preference" category).

Subject: [PATCH 035/176] fix(context_compactor): return original messages when
 compaction summary fails (#2174)

On summary LLM call failure, maybe_compact was returning system_msgs+recent
(dropping the older half) with was_compacted=False, misleading the caller into
thinking the list was unchanged. Return the original messages list unchanged so
no history is lost; the next trim_for_context call handles length if needed.

Fixes #2160

Subject: [PATCH 036/176] feat: add OpenCode Zen and Go as provider options
 (#26)

- Add OpenCode Zen (https://opencode.ai/zen/v1) and Go (https://opencode.ai/zen/go/v1)
- Add provider detection via _host_match() in llm_core.py
- Add curated model list entries in model_routes.py
- Add webhook provider URLs
- Add provider icon (providers.js) and dropdown options (index.html)
- Add auto-detection patterns and setup URLs (slashCommands.js)
- Whitelist opencode.ai in URL validation (admin.js)
- Rebased on main to fix merge conflicts with _HOST_TO_CURATED refactor

Subject: [PATCH 037/176] fix: TOCTOU race in personal file delete + IndexError
 on whitespace cmd (#2228)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. routes/personal_routes.py: os.path.exists() then os.remove() is a
   classic TOCTOU race — another request or cleanup can delete the
   file between the check and the remove, raising FileNotFoundError.
   Replace with try/except FileNotFoundError.

2. src/tool_implementations.py: cmd.split()[0] crashes with IndexError
   when cmd is a non-empty whitespace-only string (split() returns []).
   Guard with (cmd.split() or [''])[0].

Subject: [PATCH 038/176] fix(research): avoid double split() call and
 potential IndexError (#2229)

cat.split()[0] was called in the condition and again in the body,
wasting a second split. More importantly, if cat were ever
whitespace-only, split() returns [] and [0] raises IndexError.
Assign to a local variable and guard with a truthiness check.

Subject: [PATCH 040/176] fix(skills): tolerate a stray brace before the JSON
 in skill extraction (#2200)

maybe_extract_skill() sliced the LLM response from the first '{' to the
last '}'. When a model emits a stray brace in prose before the real
object (e.g. "uses {placeholder} then {...}"), the slice starts at the
prose brace, json.loads fails, and a valid skill is silently dropped.

Factor parsing into _extract_json_object(), which tries the whole
(de-fenced) string first and then each '{' start position, returning the
first candidate that parses to a JSON object.

Adds tests/test_skill_extractor_json.py.

Subject: [PATCH 041/176] fix(email): decode headers without injected spaces
 (#2433)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

routes.email_helpers._decode_header joined the runs from
email.header.decode_header() with " ". Those runs carry their own
surrounding whitespace (e.g. (b"Re: ", None)), and RFC 2047 §6.2 requires
the whitespace between two adjacent encoded-words to be dropped, so the
join produced a double space after an ASCII prefix ("Re:  Jóse"), a
spurious space in "Name <addr>" senders, and a stray space between two
adjacent encoded-words ("Café 日本"). _decode_header backs the inbox list,
message read, search, and the background pollers, so the corruption hit
essentially every non-ASCII subject/sender.

Use email.header.make_header(...) for RFC-correct concatenation, keeping
the existing lossy per-part fallback for malformed/unknown MIME charsets
(make_header raises LookupError there) so the unknown-charset contract in
tests/test_email_decode_header.py still holds.

The sibling mcp_servers.email_server._decode_header was already fixed the
same way (commit 46999de); this brings the routes.email_helpers copy in
line, with regression coverage.

Supported by Claude Opus 4.8

Subject: [PATCH 044/176] fix: port main-only fixes to dev (#2761 sharpen auth,
 #2762 doc version 404) (#3303)

* fix(gallery): add auth check to /api/image/sharpen endpoint (#2761)

Every other image-processing endpoint (denoise, upscale, remove-bg,
enhance-face, inpaint, harmonize) calls require_privilege(request,
"can_generate_images"). The sharpen endpoint was missing this check,
allowing unauthenticated users to trigger CPU-intensive image processing.

* fix(document): add 404 guard to version list/get endpoints (#2762)

list_versions and get_version used a soft 'if doc:' guard that skipped
ownership verification when the Document row was missing (e.g. after
hard delete). Orphaned DocumentVersion rows would be returned to any
caller without auth. Now raises 404 when the parent document is gone,
matching the pattern already used in restore_version.

Subject: [PATCH 045/176] fix(test): tolerate owner kwarg in compaction summary
 resolve_endpoint mock (#3304)

#2996 made context_compactor call resolve_endpoint('utility', owner=owner),
but the mock added by #2174 stubbed it as lambda which: ..., which rejects the
owner kwarg. Each PR passed alone; merged on dev the two compaction tests fail
with TypeError and the pytest job goes red. Widen the mock to lambda *a, **k.

Subject: [PATCH 046/176] feat(platform): Add support for APFEL as part of the
 dependencies and models for the Cookbook. (#2657)

* feat(platform): add support for Apple Silicon detection in platform compatibility

test(tests): enhance shell_routes tests for Apple Silicon compatibility

* fix issues with missing import

* fix: correct package name in package-lock.json and enhance package installation commands in shell_routes.py and cookbook.js

* feat: add Apfel startup and health checks on macOS

- bootstrap Apfel via Homebrew on arm64 macOS
- start `apfel --serve --port 11435` detached for Odysseus
- verify readiness via `/health`
- clean up the Apfel process on exit or Ctrl+C

* fix: duplicate variable declaration post-merge conflict
- Should fix `node` CI issues.

* fix: issues with the update status of the APFEL dependency.
- fixed by changing the main conditional that determines the update.

* Fix: Remove unnecessary whitespaces and formatting for the model_routes.py file.

* Fix: whitespace issues with the model_routes file

* Fix: Remove unnecessary whitespaces and formatting for the model_routes.py file. Final

* Fix: Fixed updates using PIP for APFEL instead of custom cmd

Subject: [PATCH 050/176] fix(hwfit): detect NVIDIA GPU on WSL and other
 minimal-PATH environments (#3306)

The nvidia-smi absolute-path fallback in _detect_nvidia() was gated
on _remote_host, so it never ran for local detection. On systems
where nvidia-smi is not in the default PATH (e.g. WSL: /usr/lib/wsl/lib/),
this caused the Cookbook to report 'No GPU' even when nvidia-smi works
from an interactive shell.

Two issues fixed:
1. Removed the _remote_host gate so the absolute-path scan runs for
   local detection too.
2. For local execution, pass arguments as a list instead of a string
   so subprocess.run() resolves the absolute path correctly. Remote
   (SSH) execution keeps the string form, which the SSH command builder
   handles.

Subject: [PATCH 051/176] fix(cookbook): don't 500 the packages panel when an
 optional package crashes on import (#2618)

list_packages() probes each optional package with importlib.import_module() but
only caught ImportError / PackageNotFoundError. A package that is installed yet
raises a different exception on import took down the whole panel with a 500,
surfaced in the UI as "Error loading packages: Unexpected token 'I', ...".

Concrete Windows case: a CUDA build of llama-cpp-python runs
os.add_dll_directory(r"...\CUDA\v12.3\bin") at import and raises FileNotFoundError
when that toolkit dir is absent. Catch any exception during the import probe and
report the package as not-installed instead of failing the entire request.

Subject: [PATCH 052/176] fix: show backend error detail in context-popup
 compact button (#2721)

When the context-popup compact button receives a non-OK response (e.g.
409 for active-run), the error detail from the backend was being
discarded in favor of a generic 'Compaction failed' message.

Now parses the JSON response body for non-OK responses and prefers the
detail field when present, matching the behavior of the /compact slash
command. Uses textContent for safe rendering.

Subject: [PATCH 054/176] fix(setup): clear error when setup runs under
 x86/Rosetta Python (#941)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a check_arch() guard that fails fast with actionable guidance when
setup runs on Apple Silicon under an Intel (x86_64) Python via Rosetta —
otherwise compiled deps (bcrypt, pydantic-core, …) load as the wrong
architecture and crash later with a cryptic "incompatible architecture"
import error. Also catch that specific error around the bcrypt import and
print rebuild steps.

Rebased onto current main: the start-macos.sh venv-Python changes that
were part of this branch are dropped, since they're already on main via
PR #978.

Subject: [PATCH 055/176] fix: make agent loopback base port env-configurable
 (#2752) (#2753)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_COOKBOOK_BASE was hardcoded to http://localhost:7000 with no env-var
override anywhere in the codebase. Tools that do an internal HTTP
loopback (app_api, trigger_research, cookbook state read/write) silently
fail with "All connection attempts failed" whenever the running uvicorn
isn't on port 7000 — which is most non-default deployments and any
side-by-side multi-instance setup. The misleading "Task triggered"
message from manage_tasks during a research request hides that the
underlying research never starts.

Resolution order, lowest to highest priority:
  1. Fallback http://127.0.0.1:7000 (preserves legacy default).
  2. APP_PORT — derive http://127.0.0.1:$APP_PORT (matches docker-compose
     which already reads APP_PORT).
  3. ODYSSEUS_INTERNAL_BASE — explicit override (e.g. behind a TLS proxy
     where loopback isn't 127.0.0.1).

127.0.0.1 instead of "localhost" avoids IPv6/DNS ambiguity for a
strictly-local call.

No API or schema change. Defaults preserved: existing setups on port
7000 are unaffected.

Caught by #2752.

Subject: [PATCH 056/176] fix(notes): handle time-first due_date phrases in
 parse_due_for_user (#3319)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

parse_due_for_user only matched day-first format ('today at 3pm').
Time-first strings like '3pm today' or '11pm today' — which the tool
schema and tool_index both advertise as valid examples — fell through
all branches, hit dateutil or the legacy _parse_dt fallback, and in
many cases raised ValueError. do_manage_notes then stored the raw
string verbatim, and the ISO-only reminder scanner (action_ping_notes)
never fired the note.

Add a time-first regex branch immediately after the day-first branch
to handle '<time> today|tonight|tomorrow|tmrw|yesterday'. Existing
day-first parsing is unchanged.

Fixes #3302

Subject: [PATCH 058/176] Add hover tooltips for clipped model names (#1982)
 (#1985)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Long model names are truncated with ellipsis in two places with no way to see
the full name: the model-picker dropdown items and the chat-header model
indicator. Add a native title tooltip carrying the full name to both — the
dropdown item's name span (nameSpan.title = m.display) and the header label
(label.title = the full model id; empty for the 'Select model' placeholder).

Subject: [PATCH 059/176] fix: search analytics FileHandler crashes on startup
 writing to read-only image layer (#2366)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix: move search analytics log to writable /app/logs volume

services/search/analytics.py opened a FileHandler at module import
time pointing to /app/services/search_engine_error.log — inside the
container image's read-only layer. The process runs as non-root so
the open() fails with PermissionError, crashing uvicorn before it
ever binds. ANALYTICS_FILE had the same problem.

Both paths now point to /app/logs (bind-mounted from the host data
directory). The FileHandler creation is wrapped in try/except so a
missing mount doesn't hard-crash on import.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: derive log dir from DATA_DIR instead of hardcoded /app/logs

Fixes reviewer feedback on #2366: /app/logs only exists inside Docker,
so native runs couldn't write the analytics file. DATA_DIR resolves to
the repo's data/ directory on native and /app/data (writable mount) in
Docker, making both the error log handler and ANALYTICS_FILE work on
every platform.

Subject: [PATCH 061/176] fix(sessions): scope enrichment queries by owner, add
 LIMIT to auto_sort (#3350)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GET /api/sessions fired full-table scans against sessions, documents, and
gallery_images on every call. Added DbSession.owner == user (line 265),
Document.owner == user (line 283), GalleryImage.owner == user (line 289),
and .limit(2000) to auto_sort_sessions (line 1013). All follow the existing
owner-scoping pattern at lines 700 and 1230. No behaviour change — the
response was already correct; this eliminates the over-fetch.

Subject: [PATCH 063/176] fix(documents): discard pending AI diff before
 switching active doc (#2484)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The document editor stores the AI-edit diff state (_diffModeActive,
_diffOldContent, _diffNewContent, _diffChunks) as a module-global
singleton bound to whatever document was active when the diff opened,
and every document shares one #doc-editor-textarea. When the active
document is switched while an unapproved diff is open, the stale diff
must be discarded first or a later exitDiffMode (tab switch /
Accept-Reject-All) flushes the old document's content into the new
active document and overwrites it (issue #2467).

Guard both paths that switch the active document for an AI update,
while activeDocId still points at the previously-active doc:
- handleDocUpdate(): a doc_update targeting a different document.
- streamDocOpen(): the AI streaming a NEW document — this runs first on
  that path, so a guard only in handleDocUpdate would fire too late and
  still overwrite the streamed document.

Both reuse the exact `if (_diffModeActive) exitDiffMode(true);` guard
switchToDoc() and enterDiffMode() already use.

Fixes #2467

+"""Regression guard for issue #2467 — cross-document overwrite via a stale AI-edit diff.
+
+document.js keeps the AI-edit diff state (``_diffModeActive`` / ``_diffOldContent`` /
+``_diffNewContent`` / ``_diffChunks``) as a module-global singleton bound to whatever
+document was active when the diff opened. ``handleDocUpdate()`` switches the active
+document (``activeDocId``) whenever an AI update targets a different doc. If a pending
+diff is not discarded first, a later tab switch (``switchToDoc`` → ``exitDiffMode(true)``)
+or Accept/Reject-All flushes the stale diff's content into the now-active document and
+silently overwrites it.
+
+The fix discards any pending diff while ``activeDocId`` still points at the
+previously-active doc, mirroring the guard ``switchToDoc()`` and ``enterDiffMode()``
+already use. It must run in BOTH places that switch the active document for an AI
+update: ``handleDocUpdate()`` and ``streamDocOpen()``. The streamed path matters most —
+when the AI creates a NEW document (the issue's own repro), ``streamDocOpen`` reassigns
+``activeDocId`` first, so a guard only in ``handleDocUpdate`` would fire too late and
+still overwrite the new doc. Kept as a static source check because document.js is
+browser-coupled and not importable in pytest.

Subject: [PATCH 065/176] refactor(tests): replace local function copies in
 test_endpoint_resolver with real imports (#3359)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor(tests): replace local function copies in test_endpoint_resolver with real imports

The test file carried 9 verbatim copies of src/endpoint_resolver.py functions
to avoid import-pollution concerns, but these copies are a drift hazard — PR #3343
had to update both in parallel.  Replace them with direct imports so future changes
to endpoint_resolver are automatically exercised by the test suite.

Also fixes _ollama_api_root in endpoint_resolver.py: the bare-URL Ollama case
(e.g. http://nas:11434 with empty path) was already handled correctly in the test
copy but was missing from the real function, which would return /chat instead of
/api/chat for native Ollama endpoints without an explicit /api prefix.

Closes #3351

* refactor: import _ollama_api_root from llm_core instead of duplicating it

endpoint_resolver already imports _detect_provider and _host_match from
llm_core. Add _ollama_api_root to that import and remove the local copy,
collapsing two implementations to one source of truth.

llm_core's version is a superset (also strips /api/chat|tags|generate paths),
and since normalize_base already removes those suffixes upstream the result
is identical for every input used here.

Subject: [PATCH 066/176] fix(security): harden untrusted_context_message
 against delimiter spoofing (#3086)

* fix(security): harden untrusted_context_message against delimiter spoofing

Root cause: untrusted_context_message() did not sanitise content before
interpolating it into the <<<UNTRUSTED_SOURCE_DATA>>> / <<<END_UNTRUSTED_SOURCE_DATA>>>
delimited sandbox block. Malicious content embedding the literal delimiter
strings could prematurely close the sandbox and inject instructions that
the LLM treats as trusted.

Fix: add _escape_guard_markers() helper that replaces the guard marker
strings with structurally inert tokens (<<<_UNTRUSTED_DATA>>> and
<<<_END_UNTRUSTED_DATA>>>) before the content is wrapped. The function is
applied in untrusted_context_message() after casting content to str.

The existing ~13 call sites (chat_processor.py, agent_loop.py,
deep_research.py, chat_helpers.py, chat_routes.py) are unaffected because
they pass content through without inspecting the output delimiters.

Regression tests added in tests/test_prompt_security.py covering:
- _escape_guard_markers unit tests (open, close, both, benign passthrough)
- untrusted_context_message integration tests (delimiter spoofing
  neutralisation, type coercion, None handling, metadata preservation)

Resolves #3056

* fix(security): sanitize label for newlines and guard markers

Addresses reviewer feedback on PR #3086:
- Normalize label: strip CR/LF to prevent pre-guard line injection
- Escape guard marker literals in label via _escape_guard_markers()
- Add regression tests for label-based newline injection, GUARD_OPEN
  and GUARD_CLOSE in label, and exactly-one-structural-guard assertion

* fix(security): move Source label inside GUARD_OPEN block

The reviewer correctly identified that even after sanitizing the label,
any user-derived label text (e.g. `f"web page: {url}"`) still appeared
before GUARD_OPEN in the trusted framing zone, where the LLM treats it
as trusted instructions.

Fix: move the 'Source: {label}' line to inside the guarded block so
only the hardcoded UNTRUSTED_CONTEXT_HEADER sits before GUARD_OPEN.
The raw label is still kept in metadata["source"] for traceability.
_sanitize_label() and _escape_guard_markers() are kept for defence-in-
depth on the label stored inside the block.

Update test_label_newline_injection_is_blocked to assert no label-
derived instruction text appears before GUARD_OPEN (pre-guard zone is
now empty of any user-derived content).

From 76c1f42ab055ae42a8106792222e2325434c1ac9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 067/176] fix: route all agent loopback calls through
 internal_api_base() helper (#3322)

#2753 made the agent loopback base port-configurable but only for
_COOKBOOK_BASE in tool_implementations. Several other in-process loopback
calls still hardcoded http://localhost:7000 and broke off port 7000:
cookbook_serve_lifecycle (model-endpoints x2, shell/exec), builtin_actions
(model/serve), task_routes (calendar x3), and the gallery/email calls in
tool_implementations.

Extract the resolution (ODYSSEUS_INTERNAL_BASE / APP_PORT / 7000 fallback,
127.0.0.1 to avoid IPv6 ambiguity) into core.constants.internal_api_base()
and route every call site through it. Rename the now-misnamed _COOKBOOK_BASE
to _INTERNAL_BASE since it serves gallery/email/calendar/serve too. Adds a
test for the resolver plus a regression guard against reintroducing the
literal.

Part of #2752.

Subject: [PATCH 068/176] fix(documents): restore PDF library metadata and
 preview (#2483)

PDF uploads are stored as markdown wrappers with pdf_source or pdf_form_source markers so the editor can preserve extracted text, form fields, and annotations. The library exposed that internal wrapper: auto-created PDF documents used the hashed storage filename as the title, and row/facet language reported markdown instead of pdf.

Derive chat-upload PDF titles from the original upload name, derive document-library display language from the PDF source marker for rows, filters, and facets, and keep markdown wrappers excluded from the markdown facet when they represent PDFs.

The expanded library card already renders PDF-backed documents through /api/document/{id}/render-pdf. Allow only that inline PDF preview endpoint to be framed by same-origin app pages while leaving normal routes on X-Frame-Options: DENY and frame-ancestors none.

Also tighten the existing PDF marker regression assertion so it matches the actual historical corruption signature instead of contradicting the preserved [Page 1 text]: marker.

Fixes #2468

 hardcoded paths and URLs (#3335)

* docs(contributing): require constants/helpers over hardcoded paths and URLs

Add a Code conventions section: don't hardcode filesystem paths or loopback
URLs, use DATA_DIR / internal_api_base() from core.constants, guard dir
creation, and add a constant when a repeated literal has none. Codifies the
class of bug behind #2366, #2752, and #3331.

Part of #3331.

 If you are unsure whether a change is "visual," it is. Default to attaching a screenshot.
 
+## Code conventions
+
+Don't hardcode values that the project already exposes through a constant or a helper. Hardcoded literals drift out of sync, break on non-default deployments, and reintroduce bugs we've already fixed.
+
+- **Filesystem paths:** never build writable paths from `Path(__file__)...` into the source tree or hardcode `/app/...`. Use `DATA_DIR` (and the other path constants) from `core.constants`, e.g. `Path(DATA_DIR) / "logs" / "x.log"`. The source tree is read-only in Docker, and `/app/...` does not exist on native runs. Guard directory creation so an unwritable path degrades gracefully instead of crashing at import.
+- **Internal API / loopback URLs:** don't hardcode `http://localhost:7000`. Use `internal_api_base()` from `core.constants` (it honors `ODYSSEUS_INTERNAL_BASE` / `APP_PORT`).
+- **Ports, limits, model lists, and similar:** reuse the existing constant if one exists; if it doesn't and the value is used in more than one place, add a constant rather than copying the literal.
+
+If you need a value that has no constant or helper yet, add one in the appropriate module (usually `core/constants.py` or `src/constants.py`) and import it, rather than repeating a literal across files.
+
+**Commits:** use [Conventional Commits](https://www.conventionalcommits.org), `type(scope): summary` (e.g. `fix(search): ...`, `feat(notes): ...`, `docs(contributing): ...`). Common types: `fix`, `feat`, `refactor`, `docs`, `test`, `chore`, `ci`. Keep the subject short and imperative; put the "why" in the body when it isn't obvious.

Subject: [PATCH 070/176] fix(search): write cache under DATA_DIR, guard mkdir
 against read-only path (#3334)

services/search/cache.py set CACHE_DIR = services/cache (the source tree) and
mkdir'd it at import, unguarded. In Docker services/ is the read-only image
layer, so the mkdir fails at import (same class as the analytics bug #2366).
Move the cache under DATA_DIR/cache (writable on Docker and native) and wrap
the mkdir so an unwritable path disables disk cache instead of crashing import.

Part of #3331.

Subject: [PATCH 073/176] ci(pr-checks): conventional-commit title check,
 unmergeable-PR flagging, pin actions by SHA (#3336)

* ci(pr-checks): add Conventional Commits PR-title check, pin actions by SHA

Add a check-title job that fails the PR when the title is not Conventional
Commits format (type(scope): summary), via an inline github-script regex.
Pin the workflow's actions to their latest release commit SHAs:
actions/checkout v6.0.3 and actions/github-script v9.0.0.

* ci(pr-checks): flag unmergeable PRs in the PR-checks workflow

Add a check-mergeable job to the (renamed) PR checks workflow: on PR events,
poll the PR's mergeable state and, when it conflicts with the base, remove
'ready for review', add a red 'merge conflict' label (auto-created), and
comment; clear the label once mergeable again. Single-PR, no push trigger.
Add ready_for_review to the trigger types.

* ci(pr-checks): drop the comment from check-mergeable, label swap only

* ci(pr-checks): least-privilege workflow permissions

contents:read for base-ref checkout, pull-requests:read for pulls.get
mergeability, issues:write for label + comment management. Drops the
unused pull-requests:write (labels and PR comments go through the issues
API).

Subject: [PATCH 074/176] fix(ci): restore pull-requests:write for PR
 label/comment writes (#3367)

#3336 reduced the PR-checks workflow to pull-requests:read on the
assumption that PR labels/comments only need issues:write (the REST path
is /issues/{n}/...). They do not: modifying a pull request's labels or
comments requires the pull-requests scope, so issues:write alone returns
403 and crashed the description check on every PR. Restore
pull-requests:write, and fail soft in swapLabel so a label-permission
error can never mask the description verdict.

Subject: [PATCH 075/176] fix: expose supports_tools toggle for local endpoints
 in UI (#3195)

* fix: expose supports_tools toggle for local endpoints in UI

Local endpoints (Ollama, vLLM, etc.) default to fenced tool blocks
when supports_tools is not set, which breaks tool calling for models
that support native function calling. The backend already supports
per-endpoint supports_tools overrides via the PATCH API, but there
was no UI to set it.

Add a 'Tools: Auto/On/Off' toggle button for local endpoints that
cycles through the three states:
- Auto (null): use the existing heuristic
- On (true): always use native function calling
- Off (false): always use fenced tool blocks

Fixes #3141

* docs: add screenshot of supports_tools toggle showing Auto/On/Off states

* Add Tools toggle screenshot for PR #3195

* refactor: convert Tools toggle to select dropdown per review feedback

Replace cycle-through button with a <select> dropdown for the
supports_tools tri-state setting. Options: Auto / On / Off with
explicit labels. Uses existing admin select styling. Fires PATCH
on change event. Same API contract (Auto=null, On=true, Off=false).

* Update Tools toggle screenshot (now dropdown select)

* fix: remove orphan screenshot and move Tools dropdown below button row

- Remove docs/screenshots/tools-toggle-three-states.png (unreferenced image causing test_no_orphan_images_in_docs to fail)
- Move Tools dropdown to its own line below Disable/Delete buttons, aligned right
- Keep Disable and Delete buttons grouped together per maintainer feedback

* fix: move Tools select onto same row left of Disable/Delete, use CSS class

Per vdmkenny feedback: move the Tools dropdown select from its own row below
the button group onto the same row, to the left of the Disable and Delete
buttons (which stay adjacent on the right). Replace inline style on the
button row with the existing .admin-ep-actions CSS class, adding
align-items:center for proper vertical alignment.

* chore: remove committed screenshots from tree

Screenshots should be in PR description/comments, not in repo history.

Subject: [PATCH 076/176] fix(skill-extractor): walk all brace candidates so
 stray braces in prose do not swallow valid JSON (#2205)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(skill-extractor): walk all brace candidates so stray braces in prose do not swallow valid JSON

The extractor sliced from the FIRST brace to the LAST brace to recover
JSON embedded in surrounding commentary. When the model emits stray
braces before the JSON object, the slice produces invalid JSON,
json.loads raises, and the exception is swallowed -- the skill is
silently lost.

Fix: walk each brace candidate left-to-right and attempt json.loads on
each slice. The first candidate that parses successfully wins. If none
parse, json.loads on the original text raises and the existing
JSONDecodeError handler logs and returns None as before.

Tested locally -- 8/8 tests passed:
  tests/test_extract_skill_json_nonstring.py (2 passed)
  tests/test_skill_extractor_rows.py (1 passed)
  tests/test_search_content_extraction_parity.py (2 passed)
  tests/test_deep_research_search_error.py (3 passed)

Closes #2199

* test(skill-extractor): add focused repro for stray-brace JSON recovery

* test(skill-extractor): add regression test for leading invalid-brace fragment

Addresses the remaining edge case from review: a response that *starts*
with a brace but the leading fragment isn't valid JSON (e.g.
'{not json}\n{"title": "Valid later", ...}') still needs to recover
the valid skill object that follows.

_extract_json_object (already on dev) handles this correctly — it tries
the whole de-fenced string first, then walks each '{' candidate left-to-
right regardless of whether the response begins with '{', so the leading
invalid fragment no longer short-circuits recovery of the real object.
Updates the comment at the call site to call this out explicitly and adds
a regression test covering exactly the scenario described in review.

Subject: [PATCH 078/176] fix(cookbook): locate cookbook_state.json via
 DATA_DIR, not hardcoded /app/data (#3332)

Three call sites hardcoded Path("/app/data/cookbook_state.json"), which only
exists in Docker; on a native run the real path is <repo>/data, so the state
file looked missing and cookbook serve-state was silently ignored. Two others
used os.environ.get("DATA_DIR", "data") (a relative fallback, since DATA_DIR is
never set as an env var). Route all five through core.constants.DATA_DIR so the
path is consistent and absolute on both Docker and native.

Part of #3331.

+# Odysseus Testing Standard & Taxonomy
+
+## Purpose
+
+This document defines *how we write and refactor tests* in Odysseus. It is the
+standard that the incremental test-suite refactor (issue #2523) works toward,
+and it applies to both human contributors and coding agents.
+
+It is intentionally split from [`tests/README.md`](./README.md):
+
+- **`README.md`** - the concrete, current helper reference: what each helper in
+  `tests/helpers/` does and how to call it.
+- **`TESTING_STANDARD.md`** (this file) - the rules and taxonomy: what a good
+  test looks like, where it belongs, and the policy refactor PRs must follow.
+
+When the two ever disagree, this file states the *intent* and `README.md` states
+the *current mechanics*; fix whichever is stale.
+
+This document changes no test behavior. It is guidance only.
+
+## What the test suite is for
+
+The goal is not only to reorganize `tests/`. The goal is for the suite to be a
+reliable foundation for future development: deterministic, modular, informative,
+behavior-focused, and complete enough to replace manual QA wherever practical.
+
+Run tests with the project virtualenv interpreter (`.venv/bin/python -m pytest`).
+The system `python3` may be missing pinned dependencies (e.g. `nh3`), which
+shows up as import/collection errors that are environmental, not real failures.
+
+## What "done" means for a single test
+
+Every new or refactored test should be:
+
+- **Deterministic** - same result every run, no reliance on wall-clock, network,
+  RNG seeds, or collection order.
+- **Behavior-first** - asserts on observable behavior, not on the source text or
+  AST of the code under test (see [Behavioral-first policy](#behavioral-first-policy)).
+- **Explicit** - setup and expected result are visible in the test, not hidden in
+  broad fixtures.
+- **Isolated from global process state** - no leaked `sys.modules`, `os.environ`,
+  CWD, or package parent-attribute mutation (see [Determinism & isolation](#determinism--isolation-rules)).
+- **Order-independent** - passes regardless of which tests ran before it.
+- **Environment-independent** - does not assume a venv layout, a developer's home
+  directory, an existing `./data` dir, or optional packages that may be absent.
+- **Informative on failure** - the assertion message or structure makes the cause
+  obvious without a debugger.
+- **Small** - understandable quickly; one behavior per test where practical.
+- **Backed by shared helpers only when duplication is proven** - not abstracted
+  preemptively.
+
+## Test taxonomy
+
+Tests are classified by the categories below. Today the suite is flat under
+`tests/`; the **Target dir** column is the phased layout from #2523 that we move
+toward *after* helpers and determinism are stable. Until a category is moved,
+new tests in that category stay in flat `tests/` but should still follow this
+standard.
+
+| Category | What it covers | Examples today | Target dir |
+|---|---|---|---|
+| **Route / API integration** | Real ASGI request/response, auth gates, admin gates, owner isolation through the app | files using `TestClient` | `tests/routes/` |
+| **CLI / script** | `scripts/` entry points and dev tooling | `tests.helpers.cli_loader.load_script` users, `test_pr_blocker_audit.py` | `tests/cli/` |
+| **Frontend / JS** | Browser-coupled JS run via Node subprocess; streaming-render invariants | `*_js.py` wrappers, `tests/streaming/*.test.mjs` | `tests/js/` |
+| **Tool execution / parsing** | Tool-call parsing, malformed/nonstring args, tool policy | `test_unknown_tool_calls.py`, `test_tool_policy.py`, `*_nonstring.py` | `tests/unit/` or `tests/services/` |
+| **LLM / provider** | Provider response parsing, streaming, sanitize, reasoning fallback | `test_llm_core_*`, `test_anthropic_response_parse.py` | `tests/services/` |
+| **Session / history / DB** | Session lifecycle, history, schema, ownership at the data layer | `test_session_*`, `test_sqlite_foreign_keys.py` | `tests/services/` or `tests/unit/` |
+| **Security / owner-scope / regression** | Owner isolation, auth, SSRF, path confinement, XSS, prompt injection, pinned regressions | `*_owner_scope.py`, `test_security_regressions.py`, `test_*ssrf*`, `test_*confinement*` | `tests/security/` |
+| **Cookbook / bootstrap** | Model serve lifecycle, dependency completion | `test_cookbook_*` | `tests/services/` |
+| **Scheduler / background** | Cron computation, background jobs, delivery | `test_compute_next_run_*`, `test_bg_*`, `test_task_scheduler_*` | `tests/services/` |
+| **Import / module isolation** | The isolation helpers themselves and their guarantees | `test_helpers_import_state.py` | `tests/unit/` |
+
+A test that genuinely spans categories (e.g. a route test that also pins a
+security invariant) is classified by its **primary** assertion target and may be
+split if it grows.
+
+## Determinism & isolation rules
+
+Do not mutate shared process state without a controlled helper and guaranteed
+cleanup. Specifically:
+
+- **`sys.modules` / parent-package attributes** - never assign at module scope.
+  Use `tests.helpers.import_state.preserve_import_state`, `clear_module`, or
+  `monkeypatch.setitem(sys.modules, ...)`. Restoring `sys.modules` alone is not
+  enough; the parent-package attribute must be restored too (the import-state
+  helpers handle both).
+- **`os.environ`** - use `monkeypatch.setenv` / `monkeypatch.delenv`, never raw
+  `os.environ[...] = ...` that outlives the test.
+- **Current working directory** - never `chdir` without restoring; never assert
+  against cwd-relative paths like `./data`. Use a temp workspace helper instead.
+- **Database** - the root `conftest.py` defaults `DATABASE_URL` to an in-memory
+  SQLite for collection safety. A test that needs a real file-backed DB must opt
+  in explicitly via `tests.helpers.sqlite_db.make_temp_sqlite` and bind its
+  `SessionLocal` onto the module under test. Do not rely on a persistent
+  on-disk DB existing.
+- **Optional dependencies** - do not require packages that may be absent in a
+  clean environment (e.g. `python-multipart`). Guard or stub them locally.
+- **Node-subprocess JS tests** - skip cleanly when `node` is absent
+  (`shutil.which("node")`), matching the existing wrappers. Treat a skip as a
+  coverage gap to be aware of, not a pass.
+- **Order independence** - a test must not depend on a sibling having imported,
+  cached, or stubbed something first. Order-sensitivity is a bug to fix, not a
+  constraint to encode.
+
+## Behavioral-first policy
+
+Prefer tests that exercise real behavior over tests that inspect source code.
+
+- **Avoid** `read_text()` + substring assertions, `ast.parse`, and
+  `inspect.getsource` checks when the behavior can be driven directly. Source-text
+  assertions break on benign refactors (renames, reformatting) and can pass even
+  when behavior regresses, because the asserted string still appears somewhere.
+- **Prefer** calling the function/route and asserting the outcome. Example: to
+  pin owner-scoping of `get_upcoming_events`, seed a temp DB with two owners and
+  assert one owner cannot see the other's events - rather than asserting the
+  source contains `q.filter(CalendarCal.owner == owner)`.
+- **Narrow exception** - a source-text/AST assertion is acceptable only when the
+  invariant cannot be practically exercised at runtime (e.g. pinning that a
+  required constant or guard literally exists in a module that is hard to drive).
+  When used, say *why* in the test docstring so it is a deliberate choice, not a
+  shortcut.
+- Do not convert source-text assertions to behavioral ones in the *same* PR that
+  moves files or changes unrelated setup.
+
+## Helper & factory extraction rules
+
+- Extract a shared helper only when the duplicated shape is **proven** - the same
+  setup repeated (ideally byte-identical) across multiple files.
+- Prefer **plain functions** in `tests/helpers/` over fixtures. Reach for a
+  fixture only when it is clearly scoped to one directory/category, and put it in
+  that directory's `conftest.py`, not the root.
+- Keep the **root `conftest.py` minimal** - `sys.path`, the DB-URL default, and
+  not-installed heavy-dependency stubs only. It is not a place for
+  feature-specific fixtures.
+- Each helper documents its **intended use and its limits** ("do not stretch this
+  to cover X"), as the existing helpers in `README.md` do.
+- Do not build a generic abstraction layer (factory framework, broad base
+  fixtures) before the repeated semantics are clear. Small and boring beats
+  clever and general.
+- Candidate factories, to add only after the duplication audit confirms the
+  shapes: fake users, fake sessions, fake requests, fake DB rows, fake LLM
+  responses, fake tool calls.
+
+## PR discipline for #2523 refactor slices
+
+- Keep each PR small, reviewable, and behavior-preserving - unless the PR's stated
+  purpose is to add new coverage.
+- **One kind of change per PR.** Do not mix:
+  - file moves with assertion changes;
+  - helper extraction with logic changes;
+  - import-state cleanup with DB-fixture changes.
+- Do not weaken assertions, add `skip`/`xfail`, or delete coverage just to make CI
+  green. A red test is a signal to investigate, not to silence.
+- Prefer 3-6 files per refactor batch, and only when they share the *same*
+  pattern.
+- Distinguish a stale test expectation from a real production-policy change before
+  "fixing" a failing test - never edit a test to match a regression.
+
+## Validation expectations
+
+Run locally before opening or approving a refactor PR:
+
+- `git diff --check` - whitespace and conflict-marker errors.
+- `python3 -m py_compile <changed .py files>` - changed files compile.
+- Focused `pytest` on the changed files (use `.venv/bin/python -m pytest`).
+- `pytest` on neighboring / order-sensitive groups that share import state with
+  the changed files.
+- When replacing boilerplate, `grep` for the old pattern to confirm no stragglers.
+- When changing a helper itself, validate in a fresh worktree so stale
+  `__pycache__` or import state cannot mask a regression.
+- For order-sensitivity, a randomized run (once `pytest-randomly` is available in
+  the dev environment) is the strongest check; record the seed on failures.
+
+## Target directory structure (phased)
+
+Move toward this layout *gradually*, only after helper conventions and
+determinism are stable. Low-risk categories move first; oversized catch-all files
+are split last.

+
+1. Add non-blocking randomized pytest reporting (`pytest-randomly`) so hidden
+   order-dependence becomes visible without changing any test.
+2. Fix surfaced order-dependence in small same-pattern batches.
+3. Add coverage reporting with no threshold gate.
+4. Only then make the pytest job a blocking CI gate.
+5. Consider `pytest-xdist` / parallel isolation after deterministic
+   single-process randomized runs are stable.

Subject: [PATCH 080/176] fix(search): catch HTTPStatusError so 403/404 URLs
 degrade gracefully instead of 500 (#2203)

raise_for_status() raises httpx.HTTPStatusError for 4xx/5xx responses,
but the surrounding try/except only caught httpx.RequestError (network
errors) and RateLimitError (429). Any other HTTP error code propagated
uncaught up through chat_processor -> chat_helpers -> chat_routes and
surfaced as a 500 Internal Server Error.

Added an explicit except httpx.HTTPStatusError clause that logs a warning
and returns an empty result, matching the behaviour already in place for
network errors.

Also adds focused regression tests that exercise the real
fetch_webpage_content() path with a mocked _get_public_url:
- 403/404 responses return the standard empty-result shape instead of
  raising, proving the new HTTPStatusError handling works end to end.
- 429 responses still take their own dedicated rate-limit branch (the
  status_code == 429 check runs before raise_for_status() is reached),
  keeping that behaviour distinct from the new generic HTTPStatusError
  handling.

Dropped the unrelated builtin_mcp.py change that had been carried over
from a rebase; that fix is tracked separately in #2018 and this branch
should stay scoped to the search content fetch path.

Closes #2148

Subject: [PATCH 081/176] fix(compare): stream Compare panes directly to stop
 upstream promptly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous approach polled request.is_disconnected() inside the
async-for body of the chat/agent streaming loops. That happens too
late: by the time the poll runs, __anext__() has already awaited and
consumed the next upstream chunk, so a slow or silent generation could
still run for a full round-trip (or until a read timeout) after the
client disconnected. It was also unconditional, which would have made
ordinary chat navigation/refresh/tab-close stop a run that the
detached-run design intentionally keeps going server-side.

Both problems trace back to the same root cause: chat_stream always
wraps its generator in agent_runs (the detached-run manager), which
decouples the generator's lifetime from the SSE response on purpose so
normal chat/agent streams survive the client going away. Polling
disconnection inside a detached generator can never be "prompt" — the
generator isn't tied to that request anymore — and doing so defeats the
whole point of detaching it.

Compare panes don't need (or want) that: each pane's session exists
only to drive that one generation, there's nothing meaningful to
/resume, and the user expects the pane's Stop button — which aborts the
fetch and closes the SSE — to cancel the upstream call right away. So
route compare-mode requests around the agent_runs wrapper entirely and
stream the generator directly as the SSE body. Starlette already
cancels a streaming response's body iterator (raising
CancelledError/GeneratorExit into it) the instant it notices the client
disconnected — including while the generator is mid-await on the next
upstream chunk — and the existing except (CancelledError, GeneratorExit)
handlers in both the chat-mode and agent-mode loops already save the
partial response exactly once. No polling needed; the redesign just
stops getting in its own way.

Normal (non-Compare) chat and agent streams are untouched and keep
going through agent_runs, preserving detached-run semantics (surviving
tab close / navigation / refresh, reconnect via /api/chat/resume).

Replaces the source-text assertions in
tests/test_compare_stop_disconnect_poll.py with runtime tests that
actually exercise the cancellation contract: a Compare-shaped generator
is cancelled mid-await (not after the next chunk arrives) and saves its
partial exactly once; a normal completion still saves exactly once via
the completion path; agent_runs keeps a detached run alive when its
subscriber disconnects and only stops it on an explicit stop()/cancel
(also saving the partial exactly once); and the cancellation contract
is pinned for both chat-mode- and agent-mode-shaped chunk sequences.

+"""Runtime coverage for stopping a Compare pane mid-stream.
+
+Replaces an earlier source-text version of this test (which only asserted on
+string positions inside routes/chat_routes.py and never exercised actual
+streaming behavior) with tests that drive the real mechanisms involved:
+
+  * src.agent_runs — the detached-run manager that normal chat/agent streams
+    are wrapped in. A subscriber (the SSE client) disconnecting must NOT stop
+    the run; only an explicit stop()/cancel does, and the wrapped generator's
+    own CancelledError handler must fire exactly once (no duplicate partial
+    saves).
+
+  * the chat_stream endpoint's compare-vs-normal branch — Compare panes must
+    be streamed directly (NOT wrapped in agent_runs), so that the pane's Stop
+    button (which closes the SSE / aborts the fetch) cancels the underlying
+    generator immediately — including while it's awaiting the *next* upstream
+    chunk, rather than only being noticed after that chunk arrives. Normal
+    chat/agent streams must still go through agent_runs so they survive the
+    client disconnecting (the existing "detached run" behavior).
+
+Together these cover: prompt stop of a Compare pane's upstream connection,
+single (non-duplicated) save of the partial response, regression-safety for
+normal completed streams, and non-interference with detached chat/agent
+streams that are meant to keep running server-side after a client disconnect.

 Don't hardcode values that the project already exposes through a constant or a helper. Hardcoded literals drift out of sync, break on non-default deployments, and reintroduce bugs we've already fixed.
 
-- **Filesystem paths:** never build writable paths from `Path(__file__)...` into the source tree or hardcode `/app/...`. Use `DATA_DIR` (and the other path constants) from `core.constants`, e.g. `Path(DATA_DIR) / "logs" / "x.log"`. The source tree is read-only in Docker, and `/app/...` does not exist on native runs. Guard directory creation so an unwritable path degrades gracefully instead of crashing at import.
-- **Internal API / loopback URLs:** don't hardcode `http://localhost:7000`. Use `internal_api_base()` from `core.constants` (it honors `ODYSSEUS_INTERNAL_BASE` / `APP_PORT`).
+- **Filesystem paths:** never build writable paths from `Path(__file__)...` into the source tree, hardcode `/app/...`, or use a relative `"data/..."` string. Every persisted file and directory has a named constant in `src/constants.py` (for example `AUTH_FILE`, `USER_PREFS_FILE`, `SETTINGS_FILE`, `TTS_CACHE_DIR`, `CHROMA_DIR`). Import and use that named constant; do not re-derive the path locally with `os.path.join(DATA_DIR, "x.json")` or `DATA_DIR / "x.json"`. `DATA_DIR` is the single place that reads `ODYSSEUS_DATA_DIR`, so use it directly only for dynamic paths that have no fixed name (for example per-owner files). If a data file or directory has no constant yet, add one to `src/constants.py`. The source tree is read-only in Docker and `/app/...` does not exist on native runs; guard directory creation so an unwritable path degrades gracefully instead of crashing at import.

 - **Ports, limits, model lists, and similar:** reuse the existing constant if one exists; if it doesn't and the value is used in more than one place, add a constant rather than copying the literal.
 
-If you need a value that has no constant or helper yet, add one in the appropriate module (usually `core/constants.py` or `src/constants.py`) and import it, rather than repeating a literal across files.
+If you need a value that has no constant or helper yet, add it to `src/constants.py` (the single source of truth for paths and config; `core/constants.py` only re-exports it for backward compatibility) and import it, rather than repeating a literal across files.
 
 **Commits:** use [Conventional Commits](https://www.conventionalcommits.org), `type(scope): summary` (e.g. `fix(search): ...`, `feat(notes): ...`, `docs(contributing): ...`). Common types: `fix`, `feat`, `refactor`, `docs`, `test`, `chore`, `ci`. Keep the subject short and imperative; put the "why" in the body when it isn't obvious.

Subject: [PATCH 083/176] feat: add ChatGPT Subscription provider (#2876)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat: Add ChatGPT Subscription support and related features

- Introduced a new provider option for ChatGPT Subscription in the endpoint selection UI.
- Implemented OAuth flow for ChatGPT Subscription sign-in, including polling for authorization status.
- Updated admin interface to handle ChatGPT Subscription, including disabling API key input and providing user guidance.
- Enhanced cost tracking logic to differentiate between subscription and non-subscription endpoints.
- Added new slash commands for managing skills, including listing, searching, and invoking skills.
- Implemented caching for skill catalog to optimize performance.
- Updated tests to cover new ChatGPT Subscription functionality and ensure proper endpoint probing.
- Refactored existing code to accommodate new features and improve maintainability.

* refactor: share provider device-flow setup

- reuse one device-flow backend for Copilot and ChatGPT Subscription
- add one frontend device-flow helper for Settings and /setup
- put GitHub Copilot back into Add Models, now as a dropdown option
- make provider selection just select; clicking Add starts sign-in
- stop ChatGPT Subscription setup from opening auth tabs automatically
- make /setup copilot and /setup chatgpt-subscription work from chat
- show ChatGPT Subscription in the /setup suggestions
- show the real error message when setup fails
- add focused tests for the shared flow and setup UI

* feat(chatgpt-subscription): harden credential lifecycle and streamline auth UX

Backend:
- Resolve runtime bearer for provider-auth endpoints at probe time via a
  shared _resolve_probe_key() that delegates to resolve_endpoint_runtime,
  applied across all probe/refresh call sites.
- Skip live completion probes and health pings for discovery-only providers
  (centralized behind _is_discovery_only_provider) — the Codex/Responses API
  has no such endpoints, so status is derived from cached models.
- Never persist the short lived ChatGPT bearer to the plaintext sessions
  table; proactively clear any stale bearer left by an earlier code path.
- Revoke orphaned ProviderAuthSession credentials when the last endpoint
  backing them is deleted (_delete_orphaned_provider_auth), surfaced via
  cleared_provider_auth in the delete response.

Frontend (admin.js):
- Auto-start the device-auth flow on provider selection so the authorization
  panel (code + Authorize) shows immediately instead of behind a "Sign in" click.
- Remove the redundant top button for device auth providers, move retry
  into the panel via an inline "Try again".
- Drop the self-evident hint text and add an execCommand clipboard fallback so
  Copy works in non-secure (HTTP/LAN) contexts.

* fix: harden chatgpt subscription provider

* chore: remove PR media from branch

* Fix chatgpt subscription recovery and token handling

Subject: [PATCH 084/176] fix: hide shell access and plan mode buttons in chat
 mode (#3417)

When in chat mode, the shell access and plan mode buttons should not be
visible. These buttons are only relevant in agent mode where the AI can
use shell commands and planning features.

Changes:
- Modified applyModeToToggles() to hide bash-toggle-btn and plan-toggle-btn
  when mode is 'chat'
- Added immediate hiding on page load to prevent flash of buttons
- Buttons are shown again when switching to agent mode

Fixes #3411

Cloners default to the dev branch (CONTRIBUTING: main is the curated

'latest code from main', so reporters confirm a stale branch and bugs
already fixed on dev get re-filed. Ask them to reproduce on latest dev.

The Inspect step had `${{ github.ref == ''refs/heads/main'' ... }}` with
doubled single quotes (YAML-scalar escaping) inside a `run: |` block, which
GitHub's expression parser rejects, failing the whole workflow at startup
(no jobs run). Replace with a plain shell conditional on $GITHUB_REF.

Subject: [PATCH 088/176] fix(endpoint): scope secondary endpoint lookups by
 owner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Scope secondary endpoint lookups by owner

* Reject unregistered image endpoint URLs for non-admins

* Adjust owner-scope tests for rebased routes

* Allow non-admins to compare endpoints they own

The compare owner-scope guard called _reject_raw_endpoint_url_for_non_admin
with endpoint_id=None, so it rejected every signed-in non-admin
/api/compare/start request — even for endpoints the caller owns — because
compare resolves endpoints by URL and carries no endpoint_id. That locked
non-admins out of compare entirely.

Resolve the owned ModelEndpoint first and pass its id, so a registered
endpoint the caller owns is allowed while only truly raw, unregistered URLs
are rejected (mirrors the gallery inpaint/harmonize checks in this PR).
Replace the source-only reject test with deterministic reject + allow
regressions that no longer depend on the dev DB contents.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* Bind compare sessions to the resolved owner-scoped endpoint

/api/compare/start created the [CMP] helper sessions with the raw
caller-supplied endpoint URL and only used the owner-scoped lookup to
decide whether to copy an API key. That stopped key borrowing but still
let a non-admin inject an arbitrary raw endpoint URL into the compare
session path.

Now, when the supplied URL resolves to a registered endpoint visible to
the caller, the session binds to that row's own normalized base URL
(build_chat_url(normalize_base(ep.base_url))) plus its headers — the same
registered-endpoint shape session_routes uses. The raw URL survives only
when ep is None, which non-admins already hit a 403 on, leaving raw URLs
reachable solely for admins / single-user mode with no borrowed key.

Adds compare-specific behavior tests: another user's private endpoint is
rejected (nothing created), the session binds to the stored URL rather
than the raw input, and an admin raw URL is allowed but carries no
inherited key.

Addresses the review on #1511.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* Validate both compare endpoints before creating any session

start_comparison resolved + created each [CMP] session inside one loop,
so a request pairing a valid owned endpoint A with an unregistered raw
endpoint B raised 403 only after A's session was already created — and
its Authorization header copied in. The rejected request left a partial
compare session with that header behind.

Split the flow into two phases: phase 1 resolves and owner-validates
both endpoints (running the raw-URL reject helper) and stashes the
session URL + headers; phase 2 creates the two sessions only once both
passed. A 403 on either endpoint now aborts with nothing created and no
header copied.

Adds a regression test: owned endpoint A + unregistered/raw endpoint B
-> 403 with no sessions created.

Addresses the follow-up review on #1511.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* Resolve compare credentials by endpoint id, not URL alone

Two endpoints visible to a caller can share a base_url but hold different
api_keys. _owned_endpoint_by_url returned whichever row sorted first, so
/api/compare/start could copy the wrong key into the [CMP] session.

Add _owned_endpoint_by_id (same owner scoping) and optional endpoint_a_id/
endpoint_b_id form fields. The id pins the exact registered endpoint; URL
resolution remains only for legacy/admin raw-URL callers. An id the caller
can't see 404s instead of falling back to a same-URL row.

* Loosen research-routes owner-scope assertion to the stable substring

The rebased _resolve_research_endpoint generalized its owner derivation to
honor an explicit owner arg first (owner = owner or getattr(sess, ...)), so
the exact-line assertion broke CI. Assert the stable session-derivation
substring instead of the full line.

Subject: [PATCH 089/176] feat(chat): recall last user message on empty
 composer ArrowUp (#1175)

Pressing ArrowUp on an empty #message composer restores the last sent user text, matching common chat-app UX (Slack, Discord, ChatGPT).

- Read from #chat-history .msg-user dataset.raw (same path as resend/regenerate), not session sidebar metadata

- Literal empty check (whitespace-only drafts are preserved); ignore Shift/Alt/Ctrl/Meta and IME composition

- Extract wiring to composerArrowUpRecall.js; rAF + 250ms retry only (no global MutationObserver)

- Add tests/test_composer_arrow_up_recall_js.py

+# Outlook / Office 365 email accounts
+
+Odysseus email accounts currently use IMAP and SMTP with username/password
+authentication. That works for providers that still allow app passwords or
+mailbox passwords for IMAP/SMTP.
+
+Microsoft disables basic authentication for Outlook and Microsoft 365 in most
+modern accounts and tenants. If you try to add an Outlook account with a normal
+password, Microsoft may return errors such as:
+
+- `IMAP: AUTHENTICATE failed`
+- `SMTP: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled`
+
+This is expected. Odysseus does not support Microsoft OAuth or Graph Mail yet,
+so Outlook / Office 365 accounts cannot currently be added through the password
+form. Use another email provider with app-password support, or track the future
+Microsoft Graph OAuth integration.

 explicitly drops in tidy (#3455)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(memory): only delete memories the model explicitly drops in tidy

The AI memory-tidy path computed deletions as the complement of the model's
`keep` list (`if mid not in keep_ids: continue`). When the model returned a
valid response that simply omitted some existing ids — a common LLM lapse — every
omitted memory was silently deleted, even though it was neither a duplicate nor
listed in `drop`.

Honor the explicit `drop` set instead: delete only ids the model dropped (minus
any it saw only truncated), and preserve everything else, still applying cleaned
text/category from `keep`.

Adds tests/test_consolidate_memory_explicit_drops.py: a memory the model omits
from both keep and drop survives; an explicitly dropped one is removed.

* refactor(memory): remove now-dead keep_ids from tidy

After deletion switched to drop_ids and text/category rewrites to cleaned_by_id,
keep_ids was written but never read. Remove the init, the .add(mid) in the keep
loop, and the truncated .update() (its truncated-protection is already covered by
`drop_ids -= truncated_ids`). Pure deletion, no behavior change; tests stay green.

Addresses review feedback on #3455.

Subject: [PATCH 094/176] fix(caldav): skip the prune when any object fails to
 parse (#3454)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(caldav): don't prune the whole window when no objects could be parsed

The post-sync prune deletes local origin=="caldav" rows in the window whose UID
the server didn't just return. With an empty seen_uids it falls back to
`uid.isnot(None)` — a match-all delete. That's right when the calendar is
genuinely empty, but when the server returns objects and every one fails to
parse (malformed iCal / an icalendar error), seen_uids is empty only because
nothing could be read, so the match-all branch silently deletes every local
event in the 90-day-back/365-day-forward window.

Track whether any object failed to parse and gate the prune with a small pure
helper `_should_prune_window(seen_uids, parse_failed)`: prune when something was
read, or when the calendar is genuinely empty (no objects, no parse errors), but
never when objects came back unreadable.

Adds tests/test_caldav_prune_parse_failure.py for the three cases.

* fix(caldav): skip the prune on any parse failure, not just total

Review follow-up (#3454): _should_prune_window returned True whenever seen_uids
was non-empty, so a partial parse failure (say 48 of 50 objects parse) still
pruned the 2 unreadable-but-still-upstream events, because their UIDs were absent
from seen_uids. Any parse failure makes seen_uids an incomplete view of the
server, so pruning against it is unsafe whether the failure is total or partial.

Skip the prune on any parse failure (return not parse_failed); only prune on a
clean read (a genuinely empty window is still safe to prune). Tradeoff: one
permanently-unparseable event pauses deletion mirroring until it is fixed, which
is the safe direction (false-keep beats false-delete).

Replace the now-incorrect "partial failure still prunes" assertion with a
partial-failure regression: one object parses, one fails, so the prune is
skipped and the unparsed event's local copy is not deleted.

Subject: [PATCH 095/176] fix(presets): persist presets atomically to avoid
 corruption on crash (#2169)

PresetManager.save() used a plain open("w") + json.dump, which truncates
presets.json before writing the new content. A crash, power loss, or
serialization error mid-write leaves the file truncated/empty and every
saved preset is lost.

Route the write through core.atomic_io.atomic_write_json (tmp file +
os.replace), matching how the rest of the codebase persists JSON state.
The helper is imported lazily so this module stays free of the heavy core
package import graph at module load time.

Adds tests/test_preset_atomic_save.py covering the source contract, a
failed-write leaving the existing file intact, and a round trip.

Subject: [PATCH 096/176] fix(api-tokens): preserve scopes on a partial token
 update (#3407)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PATCH /api/tokens/{id} unconditionally recomputed scopes from
payload.get("scopes"). On a rename — body {"name": "..."} with no "scopes"
key — that is None, so _normalize_scopes(None) returned the default ["chat"]
and the handler overwrote token.scopes, silently dropping every scope the
token had been granted (e.g. email:read, calendar:write).

Only write scopes when the request actually includes them, and return the
token's real stored scopes in the response (matching the GET /tokens display
shape) instead of the recomputed default.

tests/test_api_token_routes.py: add rename-preserves-scopes,
explicit-scopes-applied, and missing-token-404 cases for the PATCH handler.

Subject: [PATCH 097/176] fix(memory): make auto-memory extraction reliable for
 reasoning models (#3190)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(memory): auto-memory extracted nothing — flatten window so the prompt ends on a user turn

extract_and_store appended the recent window as raw alternating role messages
after the system prompt. Since the window is the last N messages, the prompt
usually ENDED on an assistant turn — and a chat model given a prompt ending on
an assistant turn returns an empty completion (nothing to answer). The result
was facts=[] → "Auto memory extraction ran: 0 candidates" on every run, so no
memories were ever stored, while skill extraction (which flattens the transcript
into a single user message) worked fine.

Flatten the window into one user message ending with an explicit instruction,
mirroring the skill extractor, so the model always responds. Also harden parsing
for reasoning models, matching the audit path which already does this:
- raise max_tokens 500 → 4096 (a reasoning model spends the budget on <think>
  before emitting JSON; 500 truncated it before any JSON appeared);
- strip <think>/prose preambles via strip_think and slice the embedded JSON
  array before json.loads, instead of bombing on char 0.

* chore: tighten memory-extraction-empty-completion — clarify JSON-slice comment re prior strip steps

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs(memory): reframe the comment to the accurate root cause (raw-chat framing)

The earlier comment leaned on "ends on an assistant turn -> empty completion",
which is only one failure mode. The dominant cause, confirmed by a controlled
repro (0/6 old vs 6/6 new on this model), is that passing the window as raw chat
messages makes the model treat it as a conversation to continue rather than a
transcript to analyze, so it returns [] even when durable facts are present.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* test(memory): cover extraction JSON parsing + slice trailing commentary unconditionally

Factor the strip/fence/slice/json.loads logic out of extract_and_store into
a pure module-level helper _parse_extraction_json(raw) -> list and drop the
'text[0] != "["' guard so the array is sliced whenever both brackets exist
(fixes trailing commentary like '[...] Done!' reaching json.loads).

Subject: [PATCH 098/176] fix(security): fail closed in /api/models auth gate
 on unexpected errors (#3489)

GET /api/models swallowed any non-HTTPException raised while checking
whether the caller is authenticated (bare except Exception: pass), so a
broken auth_manager or an exception from get_current_user silently
granted the full model list to an anonymous caller instead of rejecting
the request. Now any unexpected exception logs and returns HTTP 500.

Split out of #2360 per reviewer request to keep the deny-list and the
auth-gate fix as separate, single-purpose PRs.

Subject: [PATCH 099/176] fix(sessions): copy message metadata when forking a
 session (#3409)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fork_session passed each source message's metadata dict by reference into the
new session. add_message() -> _persist_message() stamps _db_id (and timestamp)
onto that dict in place, so persisting the fork overwrote the SOURCE messages'
_db_id with the forked rows' ids — silently breaking edit/delete-by-id on the
original conversation.

Copy the metadata dict per message so the fork and source no longer alias.

Adds tests/test_fork_session_metadata.py asserting the source session's
message metadata is unchanged after a fork.

Subject: [PATCH 100/176] ci: harden existing workflows for the security gate
 (#3498)

Pin actions to commit SHAs, set persist-credentials: false on every
checkout, and scope token permissions to the jobs that use them. Suppress
the two findings that are safe by design: the description bot's
pull_request_target trigger (no fork code runs) and an intentional
word-split in the docker manifest step.

Clears actionlint and zizmor against dev so the blocking gate from #1314
can pass once both land.

Subject: [PATCH 101/176] fix(presets): scope expand-prompt model resolution to
 owner (#3477)

* fix(presets): scope expand-prompt model resolution to owner

/api/presets/expand resolved its model endpoint with no owner, so in a
multi-user setup it could match another user's endpoint and use its URL
and decrypted api_key. Pass effective_user(request) to _resolve_model so
resolution is owner-scoped. Adds a regression test.

* fix(presets): scope teacher and audit model resolution to owner

Subject: [PATCH 102/176] fix(email): close IMAP socket when connect/login
 fails (#3174) (#3363)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(email): close IMAP socket when connect/login fails (#3174)

_imap_connect opened a live socket via _open_imap_connection and then
called conn.login() with no try/finally, and _open_imap_connection called
conn.starttls() unguarded. When auth fails (e.g. an Office 365 app password
on an MFA-enabled tenant, #3174) or STARTTLS is rejected, the already-open
socket was orphaned. Every IMAP caller funnels through _imap_connect,
including the 30-minute _auto_summarize_poller, so a persistently
misconfigured account leaked one descriptor per pass toward FD exhaustion.

The previously merged leak fixes (#1325/#1330/#1423/#1530) only guard the
post-connect body and monkeypatch _imap_connect to succeed, so this
connect-time path was uncovered. Wrap login() and starttls() so a failure
calls conn.shutdown() (low-level close; logout() can't run pre-auth) before
re-raising. Adds two regression tests that fail without the guard.

* fix(email): guard MCP IMAP+SMTP connect-time leaks too (#3174)

Folds in the sibling connect-time leaks vdmkenny flagged on #3363, so the
whole connect-then-step leak class is closed in one place:

- mcp_servers/email_server.py::_imap_connect — guard starttls() and login();
  close pre-auth with conn.shutdown() before re-raising.
- mcp_servers/email_server.py::_smtp_connect — guard starttls() and login();
  SMTP has no shutdown(), so close with conn.close() (socket close, no QUIT).

Routes SMTP (_send_smtp_message) is already safe via 'with smtplib.SMTP(...)'.
Adds four regression tests (one per guard), verified to fail without the fix.

Subject: [PATCH 103/176] fix(chat): keep balanced trailing ')' when extracting
 URLs (#3406)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

extract_urls() stripped any trailing ')' unconditionally via
`re.sub(r'[.,;:!?\)]+$', '', url)`. That corrupts URLs that legitimately
end in a parenthesis — most commonly Wikipedia disambiguation links like
https://en.wikipedia.org/wiki/Python_(programming_language), which became
...Python_(programming_language and then 404 when fetched by the web/research
tools.

Strip trailing sentence punctuation as before, but only drop a ')' when it is
unbalanced (more ')' than '('), so a prose-glued "(see https://example.com)"
still loses its closing paren while balanced URLs keep theirs.

Added tests/test_extract_urls.py covering balanced, unbalanced, nested, and
trailing-punctuation cases.

Subject: [PATCH 104/176] fix(agent): stop treating illustrative Markdown
 fences as tool calls for native function-calling models (#3356)

* fix(agent): stop executing illustrative Markdown fences as tool calls for native function-calling models

_resolve_tool_blocks fell back to the textual parse_tool_blocks() fenced-block
parser whenever a model produced no native tool_calls, regardless of whether
that model has a reliable native function-calling channel. Native models
(GPT/Claude/Grok/Qwen3/DeepSeek-V, etc. - _is_api_model true) commonly write
illustrative ```bash/```python/```json examples in guide-only prose; the
fallback parser matched these and executed them as real commands, sometimes
looping for several rounds as the model tried to clarify with more examples
(#3222).

Restrict the textual fenced-block fallback to non-native models, which rely
on it as their only tool-invocation channel. Native models are trusted to use
their structured tool_calls channel for real invocations; when they don't
emit one, a bare fence in their response is prose, not an action. The native
tool_calls path itself is untouched.

This sits one layer below #3088's guide-only policy enforcement: that PR
blocks tool exposure/execution on explicit no-tools requests, while this fixes
the parser so ordinary illustrative fences are never misread as calls in the
first place, on any turn.

* fix(agent): gate only the fenced-example pattern for native models, preserve DSML/invoke recovery and persistence

_resolve_tool_blocks previously short-circuited the entire textual parser
(tool_blocks = [] if is_api_model else parse_tool_blocks(...)) for native
function-calling models with no native tool_calls. That also dropped Patterns
2-5 (explicit [TOOL_CALL]/<invoke>/<tool_code>/DSML markup leaked into content
as text), which are real calls a model couldn't emit on its structured channel
(e.g. DeepSeek-V falling back to DSML), not illustrative examples.

parse_tool_blocks/strip_tool_blocks now take a skip_fenced flag that gates ONLY
Pattern 1 (the fenced ```bash/```python/```json block matcher). _resolve_tool_blocks
passes skip_fenced=is_api_model so fenced examples stop being executed for
native models while [TOOL_CALL]/<invoke>/<tool_code>/DSML stay fully active and
recoverable. cleaned_round mirrors the same gate when persisting round text, so
an illustrative fence that wasn't executed isn't stripped from saved/reloaded
history either (it was streaming once and then disappearing on reload).

Subject: [PATCH 105/176] fix(auth): per-user allowed-models checklist ignores
 cache, [None] doesn't block (#3355)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three issues combined to make the per-user 'Allowed models' checklist
unreliable (#3032):

1. admin.js _loadModelsForUser fetched /api/models, which is backed by
   cached_models — endpoints that haven't been probed yet (e.g. a
   freshly-added DeepSeek API endpoint) simply didn't show up in the
   checklist. Switched to /api/model-endpoints, which always reflects
   every configured endpoint regardless of cache state.

2. _saveModels sent allowed_models: [] both when the admin clicked
   [All] (no restriction) and [None] (block everything) — the backend
   had no way to distinguish the two.

3. _enforce_chat_privileges treated an empty allowed_models list as
   'no restriction' (falsy -> skip the check), so [None] had no effect.

Added an explicit block_all_models privilege flag (defaulting to False,
and forced to False for admins) that admin.js now sets when zero models
are checked. _enforce_chat_privileges checks it first and 403s
regardless of allowed_models contents.

Subject: [PATCH 108/176] test(models): add regression coverage for Z.AI coding
 endpoint probing (#2244)

Add focused tests for the z.ai/api/coding path override:
- _match_provider_curated: 5 tests verifying coding vs base key
- _probe_endpoint: 3 tests verifying model preservation, curated
  append on partial response, and base-zai exclusion

Rebased onto dev per reviewer request.

Fixes #2230

Subject: [PATCH 110/176] refactor(tools): consolidate duplicated _truncate and
 get_mcp_manager into src/tool_utils (#3478)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor(tools): consolidate duplicated _truncate and get_mcp_manager into src/tool_utils

Move all copies of _truncate(), get_mcp_manager(), and set_mcp_manager()
into a single leaf module (src/tool_utils.py) that imports only from
src.constants. This eliminates the lazy-import hack
('from src import agent_tools' inside function bodies) in tool_execution.py
and tool_implementations.py, and fixes a latent bug: the _truncate copy in
tool_execution.py was missing the isinstance guard and would crash on None.

Also deletes mcp_servers/_common.py — it was dead code with zero callers
anywhere in the codebase, containing its own copy of truncate() and
constants that already exist in src/constants.py.

* fix(tools): route remaining get_mcp_manager imports to src.tool_utils

The maintainer's feedback flagged src/task_scheduler.py:1857 and
routes/task_routes.py:977. A project-wide search found a third call site
in src/agent_loop.py that also imported get_mcp_manager from
src.agent_tools instead of src.tool_utils.

All three are now sourced from the canonical location in src.tool_utils.

+## Running focused subsets (taxonomy markers)
+
+`tests/conftest.py` tags every test at collection time with two markers derived
+from its filename by `tests/_taxonomy.py`: an `area_*` marker (e.g.
+`area_security`) and a finer `sub_*` marker (e.g. `sub_owner_scope`). This adds
+markers only - it moves no files and changes no test behavior. Use them to run a
+focused slice:
+
+```bash
+python3 -m pytest -m area_security
+python3 -m pytest -m "area_services and sub_cookbook"
+```
+
+Areas are `security`, `routes`, `services`, `cli`, `js`, `helpers`, `unit`, and
+`uncategorized`. Classification is conservative and token-based: a file that
+matches no area keyword falls back to `area_uncategorized` with its filename as
+the sub-area. The `area_*` names are registered in `pyproject.toml`; the dynamic
+`sub_*` names are registered before collection by `pytest_configure` in
+`tests/conftest.py`, so unknown-mark warnings still flag genuine typos.
+

+filename itself as the sub-area.

Subject: [PATCH 113/176] refactor(uploads): centralize upload byte-limits in
 upload_limits.py (#3364) (#3518)

Move every per-route upload byte-limit into src/upload_limits.py as a
validated, env-overridable constant via read_byte_limit_env:

- Add GALLERY_UPLOAD_MAX_BYTES, GALLERY_TRANSFORM_UPLOAD_MAX_BYTES,
  MEMORY_IMPORT_MAX_BYTES, PERSONAL_UPLOAD_MAX_BYTES,
  EMAIL_COMPOSE_UPLOAD_MAX_BYTES, STT_MAX_AUDIO_BYTES, ICS_MAX_BYTES.
- Routes import their constant instead of defining it locally: replaces 4
  raw int(os.getenv(...)) and removes 3 hardcoded literals.
- The 3 previously-hardcoded limits (email compose, STT audio, calendar
  ICS) are now env-overridable with the same ODYSSEUS_*_MAX_BYTES naming.
- Defaults unchanged, so behavior is unchanged unless an env var is set;
  an invalid value now fails fast with a clear message instead of a bare
  int() ValueError.
- Document all env vars in .env.example and the README.

Fixes #3364

Subject: [PATCH 118/176] Cookbook UI: Ollama browser, advanced serve fold, API
 tokens form, diagnosis toolbar, polish
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Surface a lot of accumulated cookbook + UI work as a single non-agent
commit so the agent rework lands cleanly.

Highlights:
- Ollama as a first-class backend in the Cookbook:
  * Download input accepts ollama-style names (name:tag) → backend=ollama
  * /api/cookbook/ollama/library (cached scrape of ollama.com + curated
    fallback so classic models like qwen2.5 stay reachable)
  * "Browse Ollama library" toggle below Download with size chips
  * Engine=Ollama in hwfit toolbar merges the Ollama library into the
    main scan list as per-tag rows with the same Fit/Param/Quant/VRAM
    columns; click → fills Download input
- API Tokens form added to Integrations panel (matching wired
  loadTokens()/initTokenForm() that had no HTML)
- Serve panel polish: Advanced fold tightening (-8px nudges on vLLM
  checks, Extra args, Spec row), n_cpu_moe + Split Mode controls
  pulled up 8px to align with the row's checkboxes, GGUF File dropdown
  exposed for Ollama backend, GPU re-render on Edit serve restore,
  _forceBackend flag so saved serveState wins over backend detection,
  cookbook:servers-changed CustomEvent so panels don't need refresh
- Models page redesign: Add Models row (URL + hidden API key reveal +
  Type select + Scan/Ollama/Key/Test/Add icon buttons), Probe All +
  Clear-offline buttons in Added Models toolbar, offline-pill removed
  (opacity already conveys state), Engine dropdown gains Ollama option
- _ping_endpoint probes /v1/models then base, accepts 4xx as
  reachable (vLLM returns 404 on bare /v1, fully working endpoints
  were showing offline)
- Diagnosis card: × dismiss + Copy bundle buttons restored on the
  serve error feedback card
- Orphan tmux sweep re-enabled behind a 60s rate-limit + background
  Thread (off the main event loop) so dead serves get discovered
- cookbook_routes auto-register watchdog: drops the endpoint if the
  serve session exits non-zero within the first ~3min
- ollama-rocm sidecar awareness in download wrapper (`docker exec
  ollama-rocm ollama pull` when host ollama isn't installed)
- Skill extractor sets initial_status="published" when
  auto_approve_skills pref is on (audit demotes later)
- Skill list / model list / cookbook scan misc polish

Subject: [PATCH 127/176] fix(llm): suppress thinking mode for qwen3/gemma4 on
 Ollama /v1 endpoint (#3228)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(llm): suppress thinking for qwen3/gemma4 on Ollama /v1 compat endpoint

When using qwen3, QwQ, gemma4, or other thinking models via Ollama's
OpenAI-compatible /v1 endpoint, the model routes all output into its
<think>...</think> reasoning block. Since Odysseus strips thinking
content from round_response and only accumulates native tool_calls,
this produces a round with 0 chars, 0 native calls, 0 tool blocks —
the agent appears to silently do nothing.

Root cause: Odysseus classifies the /v1 endpoint as provider="openai"
(not "ollama"), so the payload is built as a standard OpenAI payload
without any Ollama-specific options. Ollama's /v1 endpoint accepts
"think": false as a top-level parameter to suppress extended thinking,
but this was never sent.

Fix:
- Add _is_ollama_openai_compat_url() to detect local Ollama /v1 URLs
- Inject "think": false in both stream_llm and llm_call_async for
  thinking models (qwen3, QwQ, gemma4, DeepSeek-R1, etc.) on this
  endpoint

Verified with qwen3:14b on Ollama 0.24: with think=False the model
correctly emits native tool_calls in a single streaming chunk and
the agent executes bash/file/web tools as expected.

* fix(llm): extend _is_ollama_openai_compat_url to match localhost on any port

Per reviewer feedback on PR #3228:

1. Generalize host detection to mirror _is_ollama_native_url: match any
   localhost/127.0.0.1/0.0.0.0/::1 host (not just port 11434) so that
   custom OLLAMA_HOST ports and container remaps are also covered.

2. Add tests/test_llm_core_ollama_thinking.py covering:
   - _is_ollama_openai_compat_url for all positive/negative URL cases
     including IPv6, non-default port, native /api path, and real OpenAI
   - Payload injection: think:false set for Ollama /v1 thinking model,
     not set for non-thinking model, not set for real OpenAI endpoint,
     and set for localhost on a non-default port (the new case)

Subject: [PATCH 128/176] fix(cookbook): allow spaces and non-ASCII characters
 in model directory paths (#3473)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(cookbook): allow spaces in model directory paths

Allow POSIX external-drive paths and Windows drive paths with spaces while keeping shell metacharacters rejected.

* fix(cookbook): also allow non-ASCII (Unicode) characters in model dir paths

The ASCII-only allowlist that rejected spaces also rejected Cyrillic,
accented Latin and CJK folder names (e.g. /Volumes/Модели,
D:\AI Models\Модели) with 400 Invalid local_dir. Switch the path
character class from [A-Za-z0-9._ -] to [\w. -] (\w is Unicode-aware on
Python 3 str patterns) so localized folder names validate, while shell
metacharacters (; & | ` $ quotes newlines) stay rejected.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(cookbook): reject local_dir path segments starting with '-'

The local_dir allowlist includes '-', so a directory like /models/-rf
(or D:\models\-rf) could be parsed as a CLI flag by hf/etc. (option
injection) — and quoting does not stop a value from being read as an
option. Guard against it inside the validator so the safety stays fully
self-contained there rather than depending on consumers' quoting.

Subject: [PATCH 129/176] fix: backup import dropping a user's skill on
 cross-tenant title/id collision (#2057)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix backup import dropping a user's skill on cross-tenant title/id collision

The skills block of import_data deduped incoming skills against
skills_manager.load_all(), which returns EVERY tenant's skills. So when
a user imports their own backup, any skill whose id or title collides
with another user's skill was silently skipped — the importing user
lost their own data. This is the same cross-tenant bug already fixed
for the memories block just above (#1743); the skills block was left
with the old pattern. Filter the dedup sets to the importing user's own
skills (owner == user); the full store is still saved back, preserving
other users' skills.

* Restore sys.modules after stubbing so backup test does not break collection of later src.* test modules

* Patch backup_routes auth helpers via monkeypatch instead of sys.modules stubs so the test is import-order robust

* Give FakeSkillsManager an add_skill method matching the disk-backed skills API

Subject: [PATCH 130/176] refactor(tools): remove dead workspace-confinement
 plumbing (#3590)

Commit e6b1009 removed the workspace feature's entry point (deleted
routes/workspace_routes.py + static/js/workspace.js and dropped the
workspace-param parsing in chat_routes), but left the downstream backend
plumbing dangling: chat_routes passed a hardcoded workspace=None into
stream_agent_loop, which forwarded it to execute_tool_block, so the
workspace value was permanently None and every workspace-gated branch
was unreachable.

Remove the now-dead code (no behavior change, since workspace was always
None):
- src/tool_execution.py: drop _resolve_tool_path_in_workspace and the
  workspace params/branches on execute_tool_block, _direct_fallback,
  _call_mcp_tool, _do_edit_file, and _resolve_search_root; restore the
  bash/python/bg cwd to _AGENT_WORKDIR.
- src/agent_loop.py: drop the workspace param on stream_agent_loop, the
  dead 'ACTIVE WORKSPACE' system-prompt block, and the workspace forward.
- routes/chat_routes.py: drop the hardcoded workspace=None arg and var.
- tests: delete test_workspace_confine.py (tested the removed feature) and
  the workspace assertion in test_tool_policy.py.

Full suite: 2903 passed, 1 skipped.

Subject: [PATCH 132/176] fix(auth): sync file-backed and in-memory owner
 caches on user rename (#3397)

The DB owner-rename loop in rename_user patched every SQL column named
owner, but three non-SQL stores were left behind:

1. session_manager.sessions -- in-memory Session objects carry s.owner
   set at server-boot time. get_sessions_for_user() does an exact
   s.owner == username check, so the renamed user chat sidebar goes empty
   until a server restart.

2. data/deep_research/*.json -- each completed research report is a
   standalone JSON file with an owner field. research_routes filters
   by d.get(owner) == user, making every report invisible to the
   renamed user.

3. data/memory.json -- a flat JSON array; each entry carries an owner
   field. memory_manager.load(owner=user) filters on it, so all memories
   vanish from the memory panel.

Fix: after the SQL loop, patch all three:
- iterate sm.sessions and update owner in-place (exposed via app.state)
- walk data/deep_research/*.json and rewrite owner with atomic_write_json
- update matching entries in memory.json with atomic_write_json

All three use the same case-insensitive lower() comparison the SQL loop
already uses. Each step is independently wrapped so a single failure
does not abort the others or the rename itself.

Fixes #3362

+"""Renaming a user must update all three owner caches, not just the SQL DB.
+
+The DB owner-rename loop in the rename_user route updates every SQL-backed
+owner column, but three file-backed / in-memory stores are left stale:
+
+1. session_manager.sessions  — in-memory session objects carry s.owner set at
+   load time; get_sessions_for_user does an exact `s.owner == username` check,
+   so the renamed user's sidebar empties until a server restart.
+
+2. data/deep_research/*.json  — each report JSON has an `owner` field;
+   research_routes filters by `d.get("owner") == user`, making every report
+   invisible after rename.
+
+3. data/memory.json  — a flat array where every entry has an `owner` field;
+   memory_manager.load(owner=user) filters on it, so all memories vanish.
+
+Regression coverage: these bugs are invisible in unit tests that mock the DB
+loop but don't exercise the file/cache patches added to the route.

Subject: [PATCH 133/176] fix(embeddings): survive numpy embeddings when
 restoring a reset lane (#3410)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a lane reset fails to rewrite the recreated collection, the recovery path
re-adds the preserved rows. It read the embeddings with
`preserved.get("embeddings") or []` and gated the loop with
`if ids and docs and old_embeddings:`. chromadb returns embeddings as a numpy
ndarray, whose truth value is ambiguous, so both expressions raise ValueError
inside the except block — the restore is abandoned and every preserved row is
lost (the collection was already deleted), exactly when the code is trying to
avoid data loss.

Use an explicit `is None` check and `len(...)`, and convert ndarray batches to
lists before re-adding.

Adds tests/test_embedding_lane_ndarray_restore.py (preserved embeddings come
back as np.ndarray); existing test_embedding_lanes.py still passes.

Subject: [PATCH 134/176] feat(providers): add NVIDIA AI provider endpoint
 support (#3456)

* feat: add NVIDIA as an AI provider (integrate.api.nvidia.com)

* feat: add NVIDIA option to provider settings dropdown and aliases

* test: add NVIDIA provider detection and endpoint tests

* Add NVIDIA to _HOST_TO_CURATED and expand non-chat model filtering

- nvidia.com -> 'nvidia' curated key for proper provider routing
- _NON_CHAT_PREFIXES: bge, snowflake/arctic-embed, nvidia/nv-embed
- _NON_CHAT_CONTAINS: content-safety, -safety, -reward, nvclip,
  kosmos, fuyu, deplot, vila, neva, gliner, riva, -parse,
  -embedqa, -nemoretriever

* Expand non-chat model filtering for NVIDIA embedding/guard/video models

Add _NON_CHAT_PREFIXES: embed, recurrent
Add _NON_CHAT_CONTAINS: topic-control, guard, calibration,
  ai-synthetic-video, cosmos-reason2

Catches remaining unfiltered non-chat models from NVIDIA catalog:
embedding (llama-nemotron-embed, embed-qa), guard (llama-guard,
nemoguard-topic-control), calibration (ising-calibration),
video (ai-synthetic-video-detector, cosmos-reason2),
recurrent (recurrentgemma-2b)

* Filter non-chat models in _probe_endpoint via _is_chat_model()

Previously _is_chat_model() was only used in the per-model probe
and _first_chat_model(), so non-chat models still appeared in the
model picker even though they were filtered in those specific paths.
Applying the filter at _probe_endpoint() return ensures non-chat
models (embeddings, safety guards, reward, calibration, video
detectors, CLIP, VLM, translation, parsing, recurrent, etc.) never
enter cached_models and never appear in the picker.

* Fix _NON_CHAT_CONTAINS to catch org-prefixed embedding models

Prefix checks (mid.startswith) miss models with org prefixes like
baai/bge-m3, nvidia/embed-qa-4, google/recurrentgemma-2b, etc.
Adding the same terms to _NON_CHAT_CONTAINS ensures they are caught
regardless of the org prefix.

Adds: embed, bge, recurrent, starcoder, gemma-2b

* fix(model-routes): drop collision-prone substrings from global non-chat filter

The NVIDIA PR added several substrings to the shared _NON_CHAT_PREFIXES
and _NON_CHAT_CONTAINS tuples. These are intended to filter out
embedding, retrieval, safety, and vision models from NVIDIA's catalog
that are not chat-completions-capable. However, four of the added
substrings collide with legitimate chat models served by other providers:

  - gemma-2b  matches google/gemma-2b-it (instruct chat model)
  - starcoder matches bigcode/starcoder2-15b (code completion model)
  - recurrent matches google/recurrentgemma-2b (language model)
  - guard     matches meta-llama/Llama-Guard-3-8B (safety classifier)

Removing these four from the global tuples keeps the NVIDIA-specific
filtering intact (safety, embedding, retrieval, and vision models are
still caught by other tokens such as content-safety, -safety, -reward,
embed, bge, -embedqa, -nemoretriever, nvclip, deplot, etc.) while
preventing false negatives for instruct/code models on other providers.

Tests added for gemma-2b-it, google/gemma-2b-it, and
bigcode/starcoder2-15b-instruct asserting they are recognized as chat
models.

* fix(nvidia): remove duplicate bge/embed tokens from _NON_CHAT_CONTAINS

Tokens already present in _NON_CHAT_PREFIXES, making the CONTAINS
entries redundant since the prefix check runs first.

Co-authored-by: Kenny Van de Maele <kenny@kvandemaele.be>

* fix(nvidia): move bge to CONTAINS, add llama-guard, remove stray blanks

Co-authored-by: Kenny Van de Maele <kenny@kvandemaele.be>

* style: fix indentation of groq and xai test cases in test_provider_endpoints.py

* docs: add implementation plan for fixing chat context drifting (#135)

* fix: make Session.history immutable + fix {}.history crash

- Session.history now exposes a COPY of the internal _history list
- add_message() replaces history with a fresh copy each time
- get_context_messages() derives from _history directly
- replace_messages() updates both _history and history
- truncate_messages() updates both _history and history
- _persist_message() line 207: fixed {}.history fallback crash
- Added 11 tests for session isolation and edge cases

Addresses #135 root cause #1: shared mutable references

* fix: task scheduler uses SessionManager methods instead of overwriting sessions

- Added ensure_task_session() to SessionManager (checks cache first)
- Task scheduler now uses ensure_task_session() instead of direct dict assignment
- Task scheduler now uses SessionManager.add_message() for message persistence
- Removed direct sess_obj.history.append() that was silently losing data

Addresses #135 root causes #2 and #3

* fix: add age guard to cleanup_empty_sessions — don't delete sessions <1h old

Prevents the cleanup task from deleting sessions that were just created
and haven't received any messages yet (message_count == 0).

Addresses #135 root cause #5

* test: comprehensive session isolation tests (10/10 passing)

* refactor: consolidate _session_manager into singleton pattern

- Added set_session_manager_instance / get_session_manager_instance to core/models
- kept backward-compat aliases (set_session_manager, get_session_manager)
- session_manager.py re-exports the singleton functions
- ai_interaction.set_session_manager now syncs with the core singleton
- context_compactor uses get_session_manager_instance() instead of getattr hack
- app.py initializes the singleton once

Addresses #135 root cause #4: fragile global wiring

* test: add concurrent session isolation integration tests

Verifies:
- Concurrent add_message to different sessions doesn't cross-contaminate
- Rapid parallel writes maintain isolation
- Read-write concurrent access is safe

All 3 async tests pass, proving the immutable history fix works under concurrency

* fix: pre-import core.models in conftest to prevent test pollution

test_agent_loop.py stubs sys.modules['core.models'] = MagicMock() at
module level during collection. Any test collected after it imports
Session as a MagicMock. Pre-importing core.models in conftest.py
before test_agent_loop.py's module-level code runs prevents this.

* fix: make .history authoritative mutable list, address PR review

Per review feedback: keep .history as the authoritative mutable list so
existing code doing .history.pop(), .history = [...], etc. still works.
Fix the cross-contamination bug by ensuring __post_init__() gives each
Session its OWN unique history list (never shared).

Changes:
- core/models.py: .history IS the authoritative list. _history aliases it.
  Each Session gets its own list in __post_init__.
- core/session_manager.py: add_message() delegates to Session.add_message()
  instead of appending directly — no double-append, single source of truth.
- tests/test_session_manager.py: updated test to reflect that .history
  references see new messages (same list, not a snapshot).
- docs/plans/2026-06-01-fix-chat-context-drifting.md: removed (not for
  shipping — useful design context but too much process/doc to ship).

All 272 tests pass (3 pre-existing failures unrelated).

* Fix session manager message persistence

* Fix session history alias regressions

* Fix session history aliasing and task delivery

Subject: [PATCH 137/176] feat(diagnostics): add consolidated service health
 endpoint for degraded-state reporting (#964)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add consolidated service health endpoint for degraded-state reporting

ROADMAP (High Priority) asks for "Better degraded-state reporting for
ChromaDB, SearXNG, email, ntfy, and provider probes." Until now there was no
single readout of which subsystems are actually working: /api/health is only a
liveness ping and each subsystem's signal lives in a different module, so a
misconfigured self-host install gives no consolidated picture.

This adds an admin-only GET /api/diagnostics/services endpoint backed by a new
src/service_health.py aggregator. Each subsystem reports a uniform
{name, status, detail, meta} where status is ok | degraded | down | disabled,
and the response rolls up an overall verdict (worst non-disabled status).

Probes are deliberately non-intrusive and safe to poll:
- ChromaDB: reads the .healthy flags on the RAG and memory vector stores.
- SearXNG: GET /healthz (2xx), falling back to the instance root (<500). No
  search query is run.
- ntfy: GET the server's built-in /v1/health. No test notification is sent.
- email: short IMAP connect+logout per configured account (no credentials in
  meta).
- providers: probe each enabled ModelEndpoint's model list (no api_key in meta).

Probe functions take their inputs as parameters and isolate the network call to
injectable callables, so they unit-test without touching the network (same
pattern as the merged provider-endpoint tests). Network probes run concurrently
off the event loop via asyncio.to_thread with bounded per-probe timeouts.

memory_vector is now passed into setup_diagnostics_routes (new optional param,
backward-compatible) so ChromaDB's vector-memory store can be reported too.

Tests: tests/test_service_health.py — 29 tests covering every status mapping
per subsystem, the overall rollup, and that no secrets leak into meta.

Verification:
  python -m pytest tests/test_service_health.py -q          # 29 passed
  python -m py_compile src/service_health.py routes/diagnostics_routes.py app.py
  python -m pytest tests/test_endpoint_resolver.py tests/test_provider_endpoints.py -q

Backend + tests only; an Admin/Settings UI badge that renders this endpoint is
a natural follow-up.

* fix(diagnostics): bound service-health wall-clock and redact secrets

Addresses review on #964.

Blocker 1 — genuinely bounded wall-clock:
- providers_health and email_health now fan out per-item probes across a
  bounded thread pool (_bounded_map) with a hard total budget (_FANOUT_BUDGET),
  instead of probing endpoints/accounts sequentially. Stragglers are reported
  as a controlled `timeout` and never block; the pool is shut down with
  wait=False so the response returns on time regardless of endpoint/account
  count.
- The IMAP connect path now honors the service-health budget: _imap_connect
  gained a pass-through `timeout` param and the probe calls it with
  _PROBE_TIMEOUT instead of the default 15s.
- collect_service_health runs the four network subsystems concurrently, each
  under a per-subsystem deadline (_SUBSYSTEM_DEADLINE), with an overall
  wait_for ceiling (_AGGREGATE_DEADLINE) as a backstop.

Blocker 2 — no secret/raw-error leakage in the response:
- _safe_url strips userinfo, query, and fragment from every URL surfaced in
  meta (searxng instance, ntfy base, provider name fallback), keeping only
  scheme/host/port/path.
- _classify_error maps every probe failure to a controlled category token
  (timeout, connection_refused, dns_error, tls_error, network_error,
  http_error, auth_or_protocol_error, …) — raw str(exception), which can embed
  credentialed URLs or server text, is never returned.

Tests (tests/test_service_health.py, +tests/test_diagnostics_service_route.py):
- URL userinfo/query redaction for searxng/ntfy/providers.
- secret-bearing exception strings map to categories and don't leak.
- multiple slow providers/accounts stay bounded (single + 25-endpoint cases).
- subsystems run concurrently; aggregate deadline yields a controlled result.
- route-level unauthenticated (401) / non-admin (403) / admin (200) coverage.

* test(diagnostics): isolate route tests so they don't leak module globals

The new route tests replaced src.service_health.collect_service_health and
routes.diagnostics_routes.require_admin via direct assignment, which persisted
for the rest of the pytest session. In CI's full alphabetical run that fake
collector (returning services=[]) leaked into the later collect_service_health
tests and failed them. Switch to monkeypatch.setattr so both are restored after
each test. No production code change.

+- **Bounded wall-clock.** Per-item probes (providers, email accounts) fan out
+  across a bounded thread pool with a hard total budget (`_FANOUT_BUDGET`);
+  stragglers are reported as a controlled `timeout` rather than blocking. The
+  aggregate adds a per-subsystem deadline (`_SUBSYSTEM_DEADLINE`) and an overall
+  ceiling (`_AGGREGATE_DEADLINE`), so the endpoint cannot hang regardless of how
+  many endpoints/accounts are configured or how slowly they respond.
+- **No secret leakage.** Even though the endpoint is admin-only, the response
+  never returns credential-bearing URLs or raw exception text: URLs are passed
+  through `_safe_url` (userinfo / query / fragment stripped) and failures are
+  mapped to controlled categories via `_classify_error`.
+
+The probe functions take their inputs as parameters (settings dict, account
+list, endpoint list, manager objects) and isolate the network call to
+``_http_get`` / injected callables, so they unit-test without touching the
+network.

+"""Focused test selection runner for the pytest taxonomy markers (issue #3442).
+
+This wraps ``pytest -m`` selection over the ``area_*`` / ``sub_*`` markers that
+``tests/conftest.py`` adds at collection time (issue #3491) so focused
+validation is repeatable and less error-prone than hand-written marker
+expressions. It builds a pytest command line and either prints it (``--dry-run``)
+or runs it.
+
+Examples:
+    tests/run_focus.py --area security
+    tests/run_focus.py --area services --sub-area cookbook
+    tests/run_focus.py --keyword taxonomy -- --maxfail=1 -q
+
+This script imports no production code and changes no test behavior. It only
+constructs and (optionally) executes a pytest invocation.

Subject: [PATCH 139/176] test(tool_execution): stop two tests leaking
 src.tool_execution into the suite (#2686)

* Make in-venv pip-fallback test independent of the runner's environment

test_pip_install_fallback_chain_propagates_failure_in_venv simulated the in-venv case by probing the real interpreter (sys.prefix != sys.base_prefix). That assumes the test runner is itself inside a venv. CI runs pytest with no venv, so venv_check reported not-in-venv, the negated guard flipped, the --user branch fired, and the assertion failed. Make venv_check exit 0 directly to simulate the in-venv condition deterministically, mirroring the outside-venv companion test.

* Stop agent-tool import shims from leaking into the admin-gate test

test_function_call_non_object_args and test_unknown_tool_calls stub heavy DB/auth deps at import time to load the real agent-tool stack, but they popped src.tool_execution and left core.auth stubbed without restoring. Popping and re-importing src.tool_execution rebinds the src package's tool_execution attribute, so test_edit_file's later 'import src.tool_execution as te' resolved to a different module object than the one execute_tool_block lives in. The monkeypatch on _owner_is_admin then missed, the non-admin edit_file gate never fired, and the edit went through (exit_code 0). Stop touching src.tool_execution and restore the heavy stubs after import. Verified the full suite is green on Linux (Python 3.11, matching CI).

Subject: [PATCH 140/176] fix(cookbook): use COOKBOOK_STATE_FILE constant for
 state path (#3623)

The module derived its state file path as Path(os.environ.get("DATA_DIR", "data"))
/ "cookbook_state.json". The correct env var is ODYSSEUS_DATA_DIR, which is
already read by src/constants.py and exported as COOKBOOK_STATE_FILE. When
ODYSSEUS_DATA_DIR is set (Docker, custom installs), the old code read the wrong
env var and silently wrote state to data/cookbook_state.json relative to CWD
while every other file resolved under the custom data directory.

Fixes #3621

Subject: [PATCH 141/176] fix(llm): remove max_output_tokens from ChatGPT
 Subscription payload (#3656)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ChatGPT's Codex API rejects any request that includes max_output_tokens,
returning HTTP 400 "Unsupported parameter: max_output_tokens". This caused
Deep Research to always fail during the endpoint probe when a ChatGPT
Subscription model was selected.

Remove the conditional that set payload["max_output_tokens"] in
_build_chatgpt_responses_payload(). The parameter is simply not sent.

Also update the two affected tests:
- Rename test_chatgpt_subscription_payload_uses_max_output_tokens →
  test_chatgpt_subscription_payload_omits_max_output_tokens
- Rename test_chatgpt_subscription_payload_omits_empty_max_output_tokens →
  test_chatgpt_subscription_payload_omits_max_output_tokens_when_zero
- Assert max_output_tokens is absent rather than present

Fixes #3650

+### Fast lane and duration visibility
+
+`--fast` runs the fast lane: the tests that are *not* marked `slow` (it adds the
+marker expression `not slow`). It composes with `--area`/`--sub-area` using
+`and`. Because no tests may be marked `slow` yet, `--fast` can initially match
+the full focused selection; it becomes a real speed-up as `slow` marks are added
+from duration evidence. Use it for quick local or reviewer feedback; it does not
+replace broader focused or full-suite validation before merge.
+
+`--durations N` and `--durations-min FLOAT` add pytest's slowest-test reporting
+so you can see where time goes. They are reporting only and do not count as a
+focus selector, so `--durations` must be combined with a real selector
+(`--area`, `--sub-area`, `--keyword`, `--last-failed`, or `--fast`).
+
+Activate or otherwise use the project Python environment before running these
+commands. The examples use `python3` intentionally to avoid hard-coding a local
+venv path.
+
+```bash
+python3 tests/run_focus.py --fast
+python3 tests/run_focus.py --area services --fast
+python3 tests/run_focus.py --area services --durations 25
+python3 tests/run_focus.py --area services --fast --durations 25 --durations-min 0.05
+```
+
+The `slow` marker is opt-in. Mark a test `slow` only with duration evidence
+(from `--durations`), not by guessing - see the fast-lane policy in
+`TESTING_STANDARD.md`.

+## Fast lane policy
+
+The fast lane is `not slow`: `tests/run_focus.py --fast` selects every test that
+is not marked `slow`. The `slow` marker is **opt-in**, and slow marks must be
+**evidence-driven from `--durations` output** - mark a test slow only when its
+measured duration shows it is genuinely expensive, never by guessing. The fast
+lane exists for quick local and reviewer feedback; it is **not** a replacement
+for broader focused or full-suite validation before merge, and a test must never
+be marked `slow` to hide a failure or skip coverage.

Subject: [PATCH 144/176] fix(tools): use _INTERNAL_BASE in serve-session
 endpoint registration (#3675)

#3322 renamed the loopback base to _INTERNAL_BASE, but a later Cookbook
commit reintroduced one call site using the old _COOKBOOK_BASE name,
raising NameError whenever the agent registers a model endpoint for a
running serve session.

Fixes #3669

Subject: [PATCH 145/176] fix(macos): start ChromaDB in start-macos.sh so tool
 calling works (#3664)

* fix(macos): start ChromaDB from start-macos.sh so tool calling works

start-macos.sh never started ChromaDB, so the tool index failed to initialize
and tool/MCP injection silently degraded on native macOS installs (no Docker).
Start a local chroma from the venv before launching, mirroring the existing
Apfel background+trap pattern: idempotent (skips if 8100 is already serving),
honors CHROMADB_HOST/CHROMADB_PORT (skips when remote), logs to a file, persists
to data/chroma, and is killed in the exit trap.

Fixes #3297

* fix(macos): bind/probe ChromaDB on IPv4 loopback to match app resolution

Binding to the literal localhost can land on IPv6 ::1 while the app connects to
localhost->127.0.0.1, leaving them unable to reach each other. Pin bind + probe
to 127.0.0.1 (0.0.0.0 still honored).

* style(macos): trim chromadb comments (present-tense, no issue refs)

Subject: [PATCH 148/176] perf(http): gzip-compress text responses (#3690)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The frontend's text assets shipped uncompressed on every cold load. Add
Starlette's GZipMiddleware. Measured on the current assets:

- style.css   1,127 KB -> 238 KB  (-79%)
- index.html    202 KB ->  35 KB  (-83%)
- chat.js       238 KB ->  60 KB  (-75%)

minimum_size=1024 skips tiny bodies; Starlette excludes `text/event-stream` by
default, so the SSE streams (chat, shell, research, model-probe — all served with
media_type="text/event-stream") are never compressed or buffered. Composes
cleanly with the existing security-header middleware. No behavioural change.

Built by OdWar -- with Claude thinking alongside.

Subject: [PATCH 152/176] fix: preserve reasoning_content in sanitized messages
 for Moonshot/Kimi (#3152)

Providers like Moonshot (Kimi K2.5/K2.6) require the reasoning_content
field to be present on assistant tool-call messages in multi-turn
conversations.  The sanitizer's allow-list was missing this field,
causing HTTP 400: 'thinking is enabled but reasoning_content is missing
in assistant tool call message at index N'.

Add reasoning_content to the allowed field set in
_sanitize_llm_messages and cover with regression tests.

Fixes #3118

+The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
+
+The licenses for most software and other practical works are designed to take away your freedom to share and change the works.  By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
+
+When we speak of free software, we are referring to freedom, not price.  Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
+
+Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
+
+A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate.  Many developers of free software are heartened and encouraged by the resulting cooperation.  However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
+
+The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community.  It requires the operator of a network server to provide the source code of the modified version running there to the users of that server.  Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
+
+An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals.  This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
+
+The precise terms and conditions for copying, distribution and modification follow.
+
+                       TERMS AND CONDITIONS
+
+0. Definitions.
+
+"This License" refers to version 3 of the GNU Affero General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.  Each licensee is addressed as "you".  "Licensees" and "recipients" may be individuals or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy.  The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the Program.
+
+To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy.  Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
+
+To "convey" a work means any kind of propagation that enables other parties to make or receive copies.  Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License.  If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
+
+1. Source Code.
+The "source code" for a work means the preferred form of the work for making modifications to it.  "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
+
+The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form.  A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities.  However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work.  For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same work.
+
+2. Basic Permissions.
+All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met.  This License explicitly affirms your unlimited permission to run the unmodified Program.  The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work.  This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force.  You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright.  Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions stated below.  Sublicensing is not allowed; section 10 makes it unnecessary.
+
+3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
+
+4. Conveying Verbatim Copies.
+You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
+
+5. Conveying Modified Source Versions.
+You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7.  This requirement modifies the requirement in section 4 to "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy.  This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged.  This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit.  Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
+
+6. Conveying Non-Source Forms.
+You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source.  This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
+
+    d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge.  You need not require recipients to copy the Corresponding Source along with the object code.  If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source.  Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling.  In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage.  For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product.  A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source.  The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information.  But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
+
+The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed.  Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
+
+7. Additional Terms.
+"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law.  If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it.  (Additional permissions may be written to require their own removal in certain cases when you modify the work.)  You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10.  If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term.  If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
+
+8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided under this License.  Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License.  If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
+
+9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy of the Program.  Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance.  However, nothing other than this License grants you permission to propagate or modify any covered work.  These actions infringe copyright if you do not accept this License.  Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
+
+10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License.  You are not responsible for enforcing compliance by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations.  If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License.  For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
+
+11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based.  The work thus licensed is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version.  For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement).  To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License.  You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
+
+12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License.  If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
+
+13. Remote Network Interaction; Use with the GNU General Public License.
+
+Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software.  This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
+
+Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work.  The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
+
+14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time.  Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation.  If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
+
+Later license versions may give you additional or different permissions.  However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
+
+15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program.  It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
+
+     <one line to give the program's name and a brief idea of what it does.>
+     Copyright (C) <year>  <name of author>
+
+     This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
+
+     This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU Affero General Public License for more details.
+
+     You should have received a copy of the GNU Affero General Public License along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source.  For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code.  There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
+
+You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.

Subject: [PATCH 154/176] fix(integrations): truncate api_call JSON lists with
 sentinel instead of mid-string cut (#3540)

* fix(integrations): truncate api_call JSON lists with sentinel instead of mid-string cut

* fix(integrations): avoid mutating response dict in-place on truncation

* fix(integrations): truncate dict responses and bound list sentinel overhead

- Dict path now walks keys in insertion order, adding them one at a time
  while checking that the accumulated dict + _truncated marker fits within
  the 12 000-char limit. Previously the marker was appended without removing
  any content, so large dicts were not actually truncated.
- List path now subtracts the sentinel's serialised size (+ element-separator
  padding) from the budget before binary-searching, so the final array
  including the sentinel stays at or under the limit.
- Add regression tests: large-dict actually-truncated, small-dict pass-through,
  and list-with-sentinel respects the size bound.

Subject: [PATCH 155/176] fix(chat): stabilize system prompt, sequence memory
 extraction, and send stable session id to preserve KV cache (#3360)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(chat): stabilize system prompt, sequence memory extraction, send stable session id to preserve KV cache

Fixes #2927. As diagnosed in the issue, three things in Odysseus's request
pattern actively destroyed local backends' (llama.cpp / LM Studio) KV-cache
continuity, forcing a full prompt re-evaluation (15-30s+) on every turn:

1. Dynamic content folded into the system prompt every turn. Both the chat
   preface (ChatProcessor.build_context_preface) and the agent system prompt
   (_build_system_prompt) injected current_datetime_prompt() — text that
   changes every minute — directly into system-role messages, which llm_core
   then concatenates into the single system message sent as the cached
   prefix. Any byte difference there invalidates the entire cache. Moved this
   to a new current_datetime_context_message() helper that returns a
   standalone user-role message, inserted near the end of the array (right
   before the latest user turn) instead of mixed into the system prompt. The
   static system prefix (preset prompt + safety policy + agent base prompt)
   now stays byte-identical across turns of the same session.

2. Memory/skill extraction side-requests competed with the main completion.
   run_post_response_tasks fired extract_and_store / maybe_extract_skill via
   asyncio.create_task — fire-and-forget coroutines that could overlap the
   next turn's main request and steal llama.cpp's limited processing slots,
   evicting the cached checkpoint. They're now queued through a new
   _run_extraction_jobs_sequentially helper that waits for the session's
   stream to go idle and runs the jobs strictly one at a time.

3. No stable session identifier was sent to local backends, so llama.cpp
   assigned a new processing slot via LRU every turn ("session_id=<empty>
   server-selected (LCP/LRU)"), losing slot affinity. Added
   _apply_local_cache_affinity() in llm_core, which sets session_id and
   cache_prompt: true on outgoing payloads — gated to self-hosted
   OpenAI-compatible endpoints only (never api.openai.com or other cloud
   providers, which reject unrecognized request fields with a 400). Threaded
   session_id through stream_llm / llm_call_async / stream_agent_loop from
   the existing Odysseus session id.

Tests in tests/test_kv_cache_invalidation_2927.py exercise the real payload-
assembly and scheduling code paths: byte-identical system prefix across two
turns of the same session (with a regression check that genuinely changed
instructions DO still change it), the dynamic time block landing as a
user-role message, extraction jobs waiting for the stream to go idle and
running sequentially, and the outgoing payload carrying a stable session_id
(same across turns of one session, different across sessions) only for
self-hosted endpoints. Updated tests/test_user_time.py for the new message
placement.

* fix(tests): accept owner= kwarg in normalize_model_id monkeypatch

The upstream normalize_model_id signature now takes an owner= keyword
argument, and chat_helpers.py passes owner=getattr(sess, "owner", None)
at the call site. Update the test stub lambda to **kwargs so it handles
the new argument without breaking, and update chat_helpers.py to forward
the owner parameter consistently.

 The `slow` marker is opt-in. Mark a test `slow` only with duration evidence
 (from `--durations`), not by guessing - see the fast-lane policy in
-`TESTING_STANDARD.md`.
+`TESTING_STANDARD.md`. `--fast` is for quick reviewer feedback and must not
+replace the full suite before merge. A `slow` mark only excludes a test from the
+fast lane; the test stays runnable directly, e.g.:

+```bash
+python3 -m pytest tests/test_auth_config_lock_concurrency.py
+python3 -m pytest -m slow

Subject: [PATCH 159/176] fix(security): don't grant tool access in the
 pre-setup window (#3506)

* fix(security): don't grant tool access in the pre-setup window

owner_is_admin_or_single_user() returned True whenever auth was not
configured, which conflated two very different states:

  - intentional single-user mode (operator set AUTH_ENABLED=false), and
  - the pre-setup window (auth enabled, but no admin created yet).

In the second state, blocked_tools_for_owner() returned an empty set, so
server-execution tools (bash/python) and other admin-only tools were
ungated. The auth middleware already 401s /api/ requests pre-setup, but a
caller that bypasses it (trusted loopback / internal-tool path) could reach
those tools before setup completed.

Treat "not configured" as admin only when auth is intentionally disabled
(AUTH_ENABLED=false), mirroring the AUTH_ENABLED parsing in app.py and
core.middleware. Single-user mode is preserved; the pre-setup window is now
non-admin as defense-in-depth.

Adds regression tests for both states.

Fixes #3201

Supported by Claude Opus 4.8

* refactor(security): reuse _auth_disabled() instead of a duplicate helper

Addresses review on #3506: src/auth_helpers.py already has _auth_disabled()
with the identical AUTH_ENABLED parse. Drop the duplicate
_auth_intentionally_disabled() and call the existing helper via a lazy import
inside owner_is_admin_or_single_user (mirroring the lazy core.auth import) to
avoid any import cycle. Removes the now-unused `import os`. Behaviour and the
two regression tests are unchanged.

Supported by Claude Opus 4.8

Subject: [PATCH 162/176] fix(ui): raw SVG markup displayed instead of search
 icon for web_search tool label (#3601)

* fix(ui): escaped SVG renders as raw markup during web_search tool label

The _toolLabels['web_search'] entry embedded an SVG HTML string
concatenated with label text. At render time the entire value was
passed through esc(), HTML-escaping <svg> tags so the icon
displayed as raw text instead of rendering visually.

Fix: separate icon from label text via a _toolIcons map. The SVG
is injected as raw innerHTML (unescaped) in .agent-thread-icon,
while the label text remains safely escaped.

* test: add behavioral test for web_search tool icon rendering

Subject: [PATCH 163/176] fix(db): close sqlite migration connections on
 exception paths (#3600)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The _migrate_* startup helpers in core/database.py opened a raw
sqlite3.connect() inside a try and called conn.close() as the last
statement in that try. If any earlier statement raised (locked DB,
unexpected schema, a failed ALTER), close() was skipped and the bare
except only logged the error — leaking the connection (file handle +
lock) for the lifetime of the process. These migrations run on every
startup.

Wrap each in the conn = None + try/except/finally pattern already used
by _migrate_chat_messages_fts in this same file, so the connection is
closed on all exit paths. 25 functions; no change on the success path.
Helpers that already close safely are left untouched: _migrate_chat_messages_fts
and _migrate_backfill_task_folders (the latter uses SQLAlchemy's
engine.connect() context manager).

Same bug class as the previously merged DB-connection-leak fix (#64)
and the IMAP logout-on-all-paths fix (#1530).

Subject: [PATCH 164/176] fix(sessions): use owner_filter for list_sessions
 queries when auth disabled (#3622)

Direct DbSession.owner == user becomes WHERE owner IS NULL when user is None
(auth disabled), hiding all sessions that carry an explicit owner. Same flaw
on the Document and GalleryImage sub-queries (active-doc and gallery badges).
Replace all three with owner_filter(), which is a no-op when user is falsy.

Fixes #3620

Subject: [PATCH 165/176] fix(auth): case-insensitive skill owner match on
 rename (#3614)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SKILL.md files written with mixed-case owner (e.g. 'owner: Alice') were
skipped because the regex had no IGNORECASE flag. _usage.json keys like
'Alice::skill-name' were missed by the startswith prefix check for the
same reason.

Both comparisons now match the same way the deep_research and memory
blocks do — case-insensitively against old_username.

Fixes #3611

Subject: [PATCH 167/176] fix(research): stop rescanning the research dir on
 every status poll (#3637)

get_status() called get_avg_duration() unconditionally, and that helper globs
and JSON-parses every file under the research data dir. The SSE status stream
polls get_status() roughly once a second, so with a few saved reports each poll
re-read and re-parsed all of them, including for sessions that are not active
(the disk branch never even used the value).

Compute avg_duration only for active sessions and memoize it on the task entry,
so a long stream computes it once instead of on every poll. Behaviour is
unchanged: active streams still report avg_duration.

Adds tests/test_research_status_avg_duration.py: an inactive session does no
avg scan, and an active session computes it once across many polls.

Subject: [PATCH 168/176] fix(contacts): tolerate non-string body in
 /api/contacts/import (#3638)

import_vcf built `text = data.get("vcf") or data.get("text") or ""`, so a
non-string JSON value (a number, list, etc.) stayed in place and the following
`text.strip()` raised AttributeError, returning HTTP 500. Coerce vcf/text/csv
with str() so non-string input degrades to the existing structured "no data"
response, matching the file's convention elsewhere.

Adds tests/test_contacts_import_nonstring.py covering non-string vcf, non-string
csv, and an empty body.

Subject: [PATCH 170/176] fix(chat): copy only the displayed reply from the
 message copy buttons (#3731)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The AI-message copy buttons copied dataset.raw, which is the full
accumulated model output — still containing the <think time="...">
reasoning block and any tool-call markup that the renderer strips for
display. Pasting therefore leaked the model's thinking, and the first
heading after </think> lost its markdown formatting because it was
glued to the closing tag.

Add chatRenderer.copyMessageText(), which mirrors the display pipeline
(stripToolBlocks then extractThinkingBlocks) and falls back to the raw
text when stripping leaves nothing (thinking-only turns), and route
both copy handlers — the message footer and the slash-reply footer —
through it. The interrupted-turn Continue flow intentionally keeps
reading dataset.raw.

Fixes #3722

Subject: [PATCH 171/176] fix(tasks): read Memory.text in classify_events
 personal context (#3640)

The classify_events task pulled user memories to give the LLM personal context,
but read `m.content`, which the Memory ORM does not have (the column is `text`).
That raised AttributeError on the first row; the surrounding except swallowed it
and logged at debug, so the personal-context block was silently always empty and
events were classified without it.

Extract the rendering into `_memory_context_lines` (reads `text`, robust via
getattr, keeps the 200-char and 40-line caps) and raise the swallowed-exception
log to warning so a future schema mismatch is visible.

Adds tests/test_classify_events_memory_text.py for the field, truncation, blank
skipping, missing-attr robustness, and the line cap.

Subject: [PATCH 172/176] fix: handle batch events format in manage_calendar
 tool (#3503)

* fix: handle batch events format in manage_calendar tool

Models like deepseek-v4-flash emit batch events array instead of individual create_event calls. The tool defaulted to list_events (no action key), so events were never created despite the model confirming success.

- Add batch normalization in do_manage_calendar

- Map start/end objects to flat dtstart/dtend strings

- Add tests for both object and flat string formats

* fix: surface partial batch failures in manage_calendar

Partial failures were silently dropped - batches with mixed success/failure would report only created count with no error visibility.

- Return non-zero exit code for any failures

- Surface both created and failed counts in response

- Include first error message for debugging

- Add test for partial failure case

* chore: strip trailing whitespace in batch normalization block

* chore: strip whitespace-only blank lines in batch events test

Subject: [PATCH 173/176] fix(startup): ping real endpoints in warmup/keepalive
 (#3641)

_warmup_endpoints called model_discovery.get_endpoints(), which does not exist
on ModelDiscovery. It raised AttributeError on every startup and on every 60s
keepalive tick, was swallowed by the outer except, and pinged nothing, so the
cold-start prevention the loop exists for never ran.

Add ModelDiscovery.warmup_ping_urls(), which resolves the /models probe URLs
from the real discover_models() output, and call it from the warmup loop via
asyncio.to_thread (discovery does a blocking port scan, so keep it off the event
loop).

Adds tests/test_warmup_ping_urls.py: resolves /models URLs from discovered
items, honors the limit, degrades to [] on discovery failure, and documents that
get_endpoints never existed.

Subject: [PATCH 175/176] fix(hwfit): tolerate non-numeric gpu_count in
 /api/hwfit/models (#3639)

* fix(hwfit): tolerate non-numeric gpu_count in /api/hwfit/models

The route did `n = int(gpu_count)` with no guard, so a non-numeric query param
like `?gpu_count=abc` raised ValueError and returned HTTP 500. Parse it
defensively (mirroring the gpu_group guard a few lines above): a malformed value
is ignored, exactly like omitting the param, and valid values still apply.

Adds tests/test_hwfit_gpu_count_nonnumeric.py: a non-numeric gpu_count returns a
ranking instead of raising, and a numeric value is still accepted.

* test(hwfit): cover non-numeric manual_gpu_count too

Follow-up to the gpu_count guard: add a regression test for the sibling
manual_gpu_count query param (the hardware simulator in _apply_manual_hardware),
which dev already guards by defaulting to 1 on a non-numeric value. This pins
that behaviour so the endpoint's count parsing is fully covered and cannot
regress to a 500.
