-# Roadmap / Help Wanted
+# Roadmap
 
-Odysseus is on a voyage, but not home yet. It works great for me (lol), but this ship is moving fast and feedback/help would be appreciated! (I don't know what I'm doing, help).
+This document provides a high-level view of the areas Odysseus is currently improving.
 
-If you see weird CSS, strange layout behavior, or a suspiciously murky corner of
-the codebase, you are probably right to stay away.
+It is directional rather than exhaustive. Priorities may change as the project evolves, defects are discovered, and maintainers learn more from implementation work and user feedback.
 
-## High Priority
+For current implementation work, see the open [GitHub issues](https://github.com/odysseus-dev/odysseus/issues). Accepted behaviour should be documented in the repository alongside the code.
 
-- SQUASH BUGS
-- Fresh install smoke tests on Linux, macOS, and Windows. Docker, native Python,
-  and WSL all need coverage.
+## Current priorities
 
-- Integration audit: do integrations even work? Confirm what works, what needs setup docs, and what should be removed or hidden. 
-- Cookbook reliability on other computers. This is probably the area most likely to need work across different machines, GPUs, drivers, shells, and Python environments.
-- Cookbook SGLang support across platforms. Make sure SGLang setup/serve works
-  predictably on Linux, Windows/WSL, macOS where possible, Docker, and common
-  NVIDIA/AMD hardware paths.
-- Deep Research model presets by hardware. Recommend approved model/parameter
-  profiles for small, medium, and large local setups so people with different
-  hardware can use Deep Research without guessing. Surface this either in Deep
-  Research settings or as a Cookbook scan/dropdown suggestion.
-- Cookbook model scan/download ranking. Prioritize newer architectures and
-  better hardware-fit models instead of scoring everything almost the same.
-  Ranking should account for architecture age, quant format, VRAM/RAM fit,
-  backend support, vision/mmproj requirements, and likely serve reliability.
-- Cookbook error feedback and logging. Failed downloads, dependency installs,
-  preflights, and serve jobs should show the actual command/output/error in the
-  UI, with copyable logs and clear next steps instead of just "crashed".
-- Agent prompt/context bloat. Agent mode is too heavy for smaller local models:
-  tool schemas, skills, memory, documents, and instructions can eat the context
-  before the user request really starts. We need slimmer prompts, better tool
-  selection, smaller default tool sets, and clearer guidance for models with
-  4k/8k/16k context windows.
-- Local model speculative decoding support. For Odysseus-tuned local models,
-  plan to ship or recommend a small same-tokenizer draft model when the serving
-  backend supports it. Early vLLM testing showed a generic `Qwen3-0.6B` draft
-  beside `Qwen3-8B` can materially reduce wall time, while an unsupported
-  DSpark conversion performed poorly. Treat this as a supported draft-model lane
-  first; keep MTP-specific packaging as future work only when the architecture
-  and runtime support are real. Judge this by time-to-success, tool correctness,
-  grammar, and unchanged target output, not tokens/sec alone.
-- Skill/tool prompt-injection audit. User-editable skills, notes, documents,
-  fetched pages, and memories should be treated as untrusted data. Keep testing
-  whether models follow malicious instructions from those surfaces.
-- Better degraded-state reporting for ChromaDB, SearXNG, email, ntfy, and provider probes.
-- Email performance audit. Fetching, searching, opening, deleting, and sending
-  email can feel slow, especially over IMAP/SMTP providers with high latency.
-  Need someone who knows mail performance to profile the current flow, identify
-  whether the bottleneck is IMAP folder select/fetch, cache invalidation,
-  attachment/body loading, SMTP handshakes, or frontend refresh behavior, then
-  propose safer caching/prefetch/batching without breaking multi-account state.
-- Provider setup/probing audit for Anthropic, Gemini, Groq, xAI, OpenRouter, OpenAI, and DeepSeek.
+### Reliability and setup
 
-## Refactor Targets
-- CSS cleanup. `static/style.css` basically Calypso's island atm.
-- Tour core helper. The onboarding tours have too much copy-pasted scaffolding; promote a shared `tour-core.js` helper before adding more tours.
-- Modal/window positioning cleanup. Some window controls have improved, but the
-  underlying popup/dropdown/fixed-position behavior is still too fragile.
-- Mobile media override discoverability. A lot of "CSS did not move" bugs are mobile `@media` overrides of the same selector; comments or linting around desktop/mobile paired rules would help.
-- Dead code pass for old routes, stale feature flags, and unused UI states.
+- Improve fresh-install and smoke-test coverage across supported environments.
+- Make provider setup, probing, and failure states more predictable.
+- Improve Cookbook reliability across hardware, operating systems, drivers, shells, and serving backends.
+- Improve degraded-state reporting and recovery guidance when optional services are unavailable.
 
-## Frontend
+### Local model workflows
 
-- Expand the Editor for quicker, more robust everyday use. Better file/document
-  handling, smoother window behavior, clearer save/export flows, stronger image
-  editing affordances, and fewer brittle edge cases.
-- Better AI integration for Notes and Todos. Notes should be easier for the
-  agent to read, update, summarize, and turn into actions. Todos should be
-  assignable to an agent from the UI, possibly through a button, task action,
-  or dedicated skill/tool flow.
-- Mobile gallery/editor polish. Easier to launch/download inpaint model or any missing pieces.
-- Accessibility pass: keyboard navigation, focus states, contrast, reduced motion.
-- Improve empty states and error messages on fresh installs.
-- Tighten first-run setup, hints, and tours so they do not repeat or fight each other.
-- Vendor CDN assets eventually for a more fully self-hosted/offline mode.
+- Improve hardware-aware model recommendations and compatibility guidance.
+- Evaluate serving optimizations, including speculative decoding, through reproducible benchmarks.
+- Improve installation, preflight checks, logging, and error reporting for local model serving.
+- Reduce prompt and context overhead for smaller local models.
 
-## Backend
+### Safety and resilience
 
-- More tests around endpoint probing and provider setup.
-- Better task scheduler defaults and visibility.
-- Backup/restore guide and helper flow for `data/`.
-- Security hardening around admin-only tools and clear docs for their risk.
+- Continue hardening tool execution, filesystem access, credentials, networking, and destructive operations.
+- Treat content from documents, notes, memories, skills, and fetched pages as potentially untrusted.
+- Improve security-focused regression coverage and operational guidance.
+- Review integrations that expand access to sensitive data or privileged operations.
 
-## Not The Focus Right Now
+### Product usability
 
-I prob shouldnt add more themes.
+- Improve first-run setup, onboarding, hints, and tours.
+- Improve accessibility, keyboard navigation, focus behaviour, contrast, and reduced-motion support.
+- Improve empty states, error messages, and recovery paths.
+- Strengthen Notes, Todos, Editor, mobile, and everyday workspace flows.
+
+### Architecture and maintainability
+
+- Reduce duplication and technical debt through focused, reviewable refactors.
+- Improve subsystem documentation as behaviour and architecture become stable.
+- Remove stale code, obsolete feature flags, and unsupported integrations.
+- Keep implementation decisions grounded in current code and verified behaviour.
+
+## Tracking work
+
+Concrete implementation tasks, defects, proposals, and technical investigations are tracked in:
+
+- [GitHub Issues](https://github.com/odysseus-dev/odysseus/issues)
+- [Contributing Guide](CONTRIBUTING.md)
+
+Maintainers may use additional private coordination tools for ownership, planning, and unresolved decisions.

+This roadmap is not a complete backlog or a guarantee that a particular item will be delivered.

 - **CSP:** nonce-based `script-src 'self' 'nonce-{nonce}' https://cdn.jsdelivr.net`. `style-src 'unsafe-inline'` is intentionally kept — `static/index.html` ships inline `<style>` blocks and JS modules set `style=""` attributes at runtime. Inline styles do not execute script so the risk is visual-only. Removing this requires templating the HTML files and auditing all JS-set style attributes.
 
+## Token-Supplied Model Endpoints
+
+Direct `/api/v1/chat` requests with a token-supplied `base_url` must use a public HTTP(S) endpoint. This restriction applies only to untrusted direct values; administrator-configured endpoints may intentionally use local or LAN URLs for private model providers.
+
 ## Known Gaps
 
 These are open, acknowledged, and contributor help is welcome:
 
 1. **No shell/filesystem sandbox.** The agent `bash` and `read_file`/`write_file` tools run as the app process user with no network egress filtering or filesystem confinement. A successful prompt-injection reaching a shell-enabled admin session can make outbound requests to internal services. See #1058 for the sandbox proposal.
 
-2. **SSRF via `/api/v1/chat` `base_url` parameter.** A chat-scoped API token can supply an arbitrary `base_url`; the server forwards the LLM request to that host without validating the scheme or address. PR #1039 fixes this.
-
-3. **`src/search/` partial consolidation.** `src.search.core` and `src.search.providers` correctly alias `services.search` via `sys.modules` replacement. `analytics`, `cache`, `content`, `query`, and `ranking` are still independent copies that can drift. The SSRF regression tests in `tests/test_webhook_ssrf_resilience.py` test `src.webhook_manager` directly (separate from search), so the safety net there is intact. See #1058.
-
-4. **Token scopes are coarse.** There is no way to grant a session a subset of the owning user's privileges. Companion/mobile tokens carry either `chat` or `admin` scope with no per-capability granularity.

+# Odysseus discovery maps
+
+Compact, code-grounded discovery maps of cross-cutting systems in the checked-in Odysseus codebase. They preserve investigation context and open factual questions; they are not canonical subsystem specifications, a feature certification, or a substitute for normal testing.
+
+> [!IMPORTANT]
+> Checked-in code is the source of truth for current behaviour. Mature subsystem specifications, where they exist, are the canonical documentation of accepted subsystem behaviour. Check code, tests, and configuration before reconciling a discovery finding. Discovery remains non-canonical.
+
+## Explore the maps
+
+| Document | Purpose |
+|---|---|
+| [Current system map](system-map.md) | Records evidence locations, confirmed local observations, and factual open questions about subsystem boundaries. |
+| [Safety boundaries](safety-boundaries.md) | Records evidence about broad authority, safeguards, confirmed risks or gaps, and unverified behaviour. |
+
+## Working rules
+
+- **Trace the code first.** Confirm the current path in source before recording a claim.
+- **Promote selectively.** When an owning mature specification exists, add a fact only when it is verified, useful, and not already represented there.
+- **Record missing ownership.** When no owning specification exists, retain the verified finding in discovery and record missing documentation ownership as a follow-up.
+- **Retain uncertainty here.** Keep unresolved questions and useful investigation context in discovery rather than treating them as canonical truth.
+- **Keep specifications current-state only.** Do not record intentions, design direction, refactor plans, decision history, priority, ownership, or sequencing here.
+- **Investigate with cause.** Do not exhaustively revalidate existing functionality without a report, visible failure, relevant change, or high-authority review need.
+- **Review authority carefully.** Give execution, data access, external tools, credentials, destructive operations, and unattended work focused review.
+- **Use stable locations.** Cite modules, routes, classes, and functions instead of fragile line ranges or generated evidence tables.
+
+## Reconciliation flow
+
+1. Start with the relevant map and trace the cited code.
+2. Classify the finding against current source evidence and an owning mature specification where one exists.
+3. Promote only verified, useful facts that are missing from an existing owning specification.
+4. When no owning specification exists, retain the verified finding here and record missing documentation ownership as a follow-up; otherwise retain unresolved context here and correct stale wording.

+## Purpose
+
+This inventory provides a reviewable map of the current repository structure,
+large runtime modules, major subsystem boundaries, and refactor-sensitive areas.

+- certify runtime correctness;
+- prescribe a committed refactor sequence;
+- replace focused specifications, tests, or source review.

+
+## Refactor-sensitive areas
+
+### Shared persistence
+
+`core/database.py` is a central dependency containing models and shared persistence
+helpers. Changes can affect routes, services, background work, tests, migrations,
+and import compatibility.
+
+A split should not begin from file size alone. It requires:
+
+- an importer inventory;
+- model and helper ownership decisions;
+- migration compatibility checks;
+- stable re-export or migration strategy;
+- focused and full-suite validation.
+
+### Agent orchestration
+
+`src/agent_loop.py` coordinates model interaction, tool selection, policy decisions,
+multi-round execution, and background behaviour. Extraction work must preserve tool
+event semantics, policy enforcement, cancellation, and test patch points.
+
+Historical agent-loop modularization discussion is tracked in
+[#3266](https://github.com/odysseus-dev/odysseus/issues/3266).
+
+### Tool implementation boundaries
+
+Tool implementation is no longer represented by one proposed future package alone.
+Current responsibilities are distributed across:
+
+- `src/tool_execution.py`;
+- `src/tool_schemas.py`;
+- `src/tool_index.py`;
+- `src/tool_policy.py`;
+- `src/tool_security.py`;
+- `src/agent_tools/`;
+- `src/tools/`;
+- remaining compatibility surfaces such as `src/tool_implementations.py`.
+
+Historical tool modularization work is tracked in
+[#3629](https://github.com/odysseus-dev/odysseus/issues/3629).
+
+### Route ownership
+
+`routes/` now contains both flat modules and domain packages. Existing package
+boundaries should be extended only through focused changes. Broad mechanical route
+movement would affect registration, imports, tests, monkeypatch targets, and
+compatibility paths.
+
+### Frontend concentration
+
+The no-build frontend contains several large JavaScript modules and one central CSS
+file. Refactors should preserve module load order, global compatibility exports,
+DOM contracts, deep-link handling, and browser behaviour.
+
+## Non-implemented architecture options
+
+> [!NOTE]
+> The paths below are historical or possible design directions. They do not describe
+> the current repository and are not approved implementation plans.
+
+Earlier planning discussed:
+
+- renaming `app.py` to `main.py`;
+- moving agent orchestration into a new `src/agent/` package;
+- introducing broad `src/domain/`, `src/infra/`, `src/api/`, or `src/pkg/` layers;
+- moving all routes into domain subpackages;
+- splitting database models into a new infrastructure hierarchy.
+
+These options should be reconsidered against the current tree rather than copied
+forward as assumed targets.
+
+## Refactor guardrails
+
+- Keep structural changes behaviour-preserving.
+- Change one ownership boundary at a time.
+- Do not mix file movement with unrelated feature work.
+- Preserve existing import and monkeypatch paths where compatibility is required.
+- Identify focused tests before modifying high-authority modules.
+- Validate startup, imports, and affected runtime paths.
+- Avoid repository-wide package reorganizations without maintainer agreement.
+- Treat generated metrics as snapshots, not architectural decisions.
+
+## Reproduce the snapshot
+
+Run these commands from the repository root.
+
+```bash
+# Tracked directory totals
+for dir in src routes core services mcp_servers scripts static/js tests; do
+  files="$(git ls-files "$dir" | wc -l)"
+  python_files="$(git ls-files "$dir" '*.py' | wc -l)"
+
+  printf '%-14s tracked=%-5s python=%-5s\n' \
+    "$dir" \
+    "$files" \
+    "$python_files"
+done
+
+# Largest tracked backend files
+git ls-files \
+  'app.py' \
+  'launcher.py' \

+  'routes/*.py' \
+  'routes/**/*.py' \
+  'services/*.py' \
+  'services/**/*.py' \
+  'src/*.py' \
+  'src/**/*.py' \
+  'mcp_servers/*.py' \
+  'scripts/*.py' \
+  'scripts/**/*.py' |
+xargs wc -l |
+sort -nr |
+head -31
+
+# Largest tracked frontend source files
+git ls-files \
+  'static/*.js' \
+  'static/*.css' \
+  'static/*.html' \
+  'static/**/*.js' \
+  'static/**/*.css' \
+  'static/**/*.html' |
+grep -vE '\.min\.js$' |
+xargs wc -l |
+sort -nr |
+head -31
+```
+
+## Validation for architecture changes
+
+Use the smallest relevant checks first, then expand according to risk:
+
+```bash
+python3 -m compileall -q app.py core routes services src
+venv/bin/python -m pytest tests/<focused-test-file>.py -q
+venv/bin/python -m pytest -q
+```
+
+Startup, browser, Docker, and integration checks may also be required depending on
+the affected boundary.

Verify the cited source before relying on a finding. No destructive test, external connection, or real credential was used for this map.

+## Navigate the boundaries
+
+- [Shell and subprocess execution](#shell-and-subprocess-execution)
+- [Filesystem access and workspace confinement](#filesystem-access-and-workspace-confinement)
+- [Agent-controlled tool dispatch](#agent-controlled-tool-dispatch)

+- [Authentication and privileged administration](#authentication-and-privileged-administration)
+- [Deletion, wipe, backup, and restore](#deletion-wipe-backup-and-restore)
+- [Background jobs and unattended task execution](#background-jobs-and-unattended-task-execution)
+
+## Shell and subprocess execution
+
+- **Boundary:** Shell routes, agent `bash` and `python` tools, local model serving, and detached background jobs.
+
+- **Available authority:** Commands run as the application process user and can create child processes.
+
+- **User-controlled inputs:** Direct shell requests, model-produced tool arguments, scheduled-task prompts, and model-serving configuration.
+
+- **Current safeguards:** Agent dispatch applies owner/admin checks and tool policy; process helpers use timeouts or bounded background-job lifecycle where implemented.
+
+- **Confirmed risks or gaps:** Intentional authority with a confirmed gap: the agent shell starts in its workspace but is not sandboxed to it, and has no egress sandbox. This is documented in source and the threat model; it is not a newly demonstrated bypass.
+
+- **Unverified behaviour:** Role-gate and disabled-tool outcomes, direct shell-route behaviour, and timeout, cancellation, and output handling for foreground and detached processes remain unverified.
+
+## Filesystem access and workspace confinement
+
+- **Boundary:** Agent read, write, patch, listing, glob, and grep tools.
+
+- **Available authority:** Read and modify files within active workspace confinement or fallback allowlisted roots.
+
+- **User-controlled inputs:** Tool paths, patches, file contents, search patterns, and workspace selection passed into the tool dispatcher.
+
+- **Current safeguards:** [`src/tool_execution.py`](../src/tool_execution.py) resolves paths, blocks sensitive subpaths, applies allowlist containment, and tightens paths to the active workspace when one is bound. File tools use those resolvers.
+
+- **Confirmed risks or gaps:** Intentional authority with safeguards. The file-tool policy does not sandbox the shell; treating a workspace as a whole-process containment boundary would be incorrect.
+
+- **Unverified behaviour:** Traversal, symlink, sensitive-name, absolute-path, and workspace-switch behaviour remains unverified.
+
+## Agent-controlled tool dispatch
+
+- **Boundary:** Model output becomes native or parsed tool calls and is dispatched by the agent loop.
+
+- **Available authority:** The authority of every enabled tool, including privileged built-ins and external tools.
+
+- **User-controlled inputs:** Chat content, attached/retrieved content that may influence the model, tool arguments, per-request tool selection, and policy toggles.
+
+- **Current safeguards:** [`src/tool_security.py`](../src/tool_security.py) blocks protected tools for non-admin users and fails closed for malformed tool names; [`src/tool_policy.py`](../src/tool_policy.py) supports disabled and guide-only policy; prompt-security helpers label untrusted context.
+
+- **Confirmed risks or gaps:** Credible risk requiring verification: aliases, legacy text tools, native function calls, and MCP-qualified names must all reach the same policy outcome. The code has specific alias handling for email/MCP names, which makes this a sensitive compatibility seam.
+
+- **Unverified behaviour:** The current policy outcomes for owner role, request mode, disabled state, native versus parsed invocation, qualified aliases, and external-content entry points remain unverified.
+
+## MCP and external tool servers
+
+- **Boundary:** Configured MCP servers and their tools are exposed to the agent through the MCP manager and routes.
+
+- **Available authority:** Depends on the server: external network access, local process access, messaging, or data mutation may be delegated outside the application.
+
+- **User-controlled inputs:** Server configuration, remote OAuth completion, tool arguments, and model-selected MCP calls.
+
+- **Current safeguards:** MCP routes are registered through [`routes/mcp_routes.py`](../routes/mcp_routes.py); MCP-qualified tools are denied to non-admin users by [`src/tool_security.py`](../src/tool_security.py). OAuth state and token persistence are handled in [`src/mcp_oauth.py`](../src/mcp_oauth.py).
+
+- **Confirmed risks or gaps:** Credible risk requiring verification: an MCP server authority is broader than the application can infer from its tool name. This map does not establish a trust or approval model for server installation and individual tool invocation.
+
+- **Unverified behaviour:** Server onboarding, credential storage, server-origin trust, OAuth callback deployment, tool disablement, and invocation audit behaviour remain unverified.
+
+## Outbound network requests and URL validation
+
+- **Boundary:** Search/content fetch, research, webhooks, skill import, provider endpoints, and other HTTP clients.
+
+- **Available authority:** The application can make outbound requests from its network position.
+
+- **User-controlled inputs:** Search/fetch URLs, imported skill URLs, webhook configuration, and some endpoint settings.
+
+- **Current safeguards:** [`src/url_security.py`](../src/url_security.py) validates untrusted public HTTP URLs and fails closed on unsuitable schemes or private addresses. [`services/search/content.py`](../services/search/content.py) resolves and rejects non-public hosts, pins resolved addresses for fetches, caps bodies, and limits redirects.
+
+- **Confirmed risks or gaps:** Intentional split: administrator-created model endpoints may target private providers, while untrusted URLs use public-address checks. That distinction is required for self-hosted deployments but needs explicit call-site review.
+
+- **Unverified behaviour:** The URL-source classification for outbound clients and the current handling of redirects and DNS changes remain unverified.
+
+## Secrets, credentials, and vault sessions
+
+- **Boundary:** Application-managed encrypted secrets, API keys, provider credentials, and Bitwarden/Vaultwarden CLI sessions.
+
+- **Available authority:** Credentials unlock remote providers and connected personal services.
+
+- **User-controlled inputs:** Administrative configuration, login/unlock requests, imported settings, and agent vault tool arguments.
+
+- **Current safeguards:** [`src/secret_storage.py`](../src/secret_storage.py) uses a locally stored Fernet key with restrictive permissions for supported database secrets. Vault routes require an administrator, avoid passing master passwords in command arguments, and set restrictive permissions on the vault-session file.
+
+- **Confirmed risks or gaps:** Confirmed current boundary: vault session data is persisted through the vault path, not through [`src/secret_storage.py`](../src/secret_storage.py). This is an unresolved question about current security semantics, not a confirmed exposure.
+
+- **Unverified behaviour:** Current encryption-at-rest, owner scope, rotation, lock/logout, backup/restore, and log/tool-result exposure behaviour remains unverified.
+
+## Authentication and privileged administration
+
+- **Boundary:** Session authentication, API tokens, privileged routes, and internal tool loopback.
+
+- **Available authority:** Administrative identity can access execution, settings, integrations, data deletion, and secrets.
+
+- **User-controlled inputs:** Login/signup data, session cookies, API tokens, authentication configuration, and requests to privileged routes.
+
+- **Current safeguards:** [`core/auth.py`](../core/auth.py), [`core/middleware.py`](../core/middleware.py), and route-level checks establish identity and administrator gates. [`app.py`](../app.py) warns when localhost bypass is configured; [`SECURITY.md`](../SECURITY.md) documents deployment requirements.
+
+- **Confirmed risks or gaps:** Intentional authority with safeguards. Security depends on deployments keeping authentication enabled and internal services private; this map does not audit reverse-proxy or environment configuration.
+
+- **Unverified behaviour:** Setup, anonymous, non-admin, admin, token, and internal-loopback behaviour, including privileged-route gate consistency, remains unverified.
+
+## Deletion, wipe, backup, and restore
+
+- **Boundary:** Administrative wipe, cleanup, backup import/export, and the backup restore command.
+
+- **Available authority:** Delete or replace user data and credentials.
+
+- **User-controlled inputs:** Administrative HTTP requests, cleanup choices, backup payloads, archive paths, and restore command options.
+
+- **Current safeguards:** Administrative wipe routes use the administrative boundary. Cleanup exposes a preview route before mutation. The documented backup tool requires explicit restore confirmation, stages the old data directory, and validates archive members before extraction.
+
+- **Confirmed risks or gaps:** Intentional destructive authority. Backup archives contain secrets by design, as documented in [`docs/backup-restore.md`](../docs/backup-restore.md); this is an operator confidentiality responsibility, not a code defect established here.
+
+- **Unverified behaviour:** Role-gate, confirmation, archive-rejection, staged-recovery, and owner-isolation behaviour remains unverified. No destructive runtime test was performed.
+
+## Background jobs and unattended task execution
+
+- **Boundary:** Scheduled tasks, background-job monitor, startup tasks, and notification/delivery work that continue without an active browser request.
+
+- **Available authority:** Scheduled agent work can obtain model access and, for eligible owners, shell and file tools; task output can interact with connected services.
+
+- **User-controlled inputs:** Stored task prompt, schedule, model/crew selection, enabled-tool configuration, output target, and prior persisted state.
+
+- **Current safeguards:** [`src/task_scheduler.py`](../src/task_scheduler.py) serializes execution, records task runs, associates work with an owner, and applies the agent owner-based tool gate. [`src/bg_jobs.py`](../src/bg_jobs.py) keeps bounded state and can terminate overlong subprocess jobs.
+
+- **Confirmed risks or gaps:** Credible risk requiring verification: authority is inherited and exercised later, so changes to roles, task configuration, and disabled tools must be checked at execution time rather than assumed from task creation.
+
+- **Unverified behaviour:** Creation, editing, role-change, scheduling, cancellation, restart-recovery, and execution behaviour remains unverified, including whether current policy is re-evaluated before privileged action.

+- [Persistence, background work, and operations](#persistence-background-work-and-operations)
+
+## Startup and application composition
+
+- **How it works:** [`app.py`](../app.py) creates the application, mounts static assets, constructs shared services, registers route factories, and owns lifespan startup and shutdown. [`src/app_initializer.py`](../src/app_initializer.py) prepares application state; [`core/`](../core/) provides persistence, authentication, middleware, sessions, and platform helpers.
+
+- **Evidence locations:** [`app.py`](../app.py); [`src/app_initializer.py`](../src/app_initializer.py); [`core/database.py`](../core/database.py); [`core/auth.py`](../core/auth.py); [`core/middleware.py`](../core/middleware.py); [`routes/`](../routes/).
+
+- **Known problems:** None recorded by this mapping.
+
+- **Open question:** Which component currently owns startup and shutdown for each long-lived service?
+
+## Frontend shell and browser interaction
+
+- **How it works:** [`static/index.html`](../static/index.html) is served by the root and SPA deep-link routes in [`app.py`](../app.py); [`static/app.js`](../static/app.js), [`static/style.css`](../static/style.css), and [`static/js/`](../static/js/) implement the client surface.
+
+- **Evidence locations:** [`static/index.html`](../static/index.html); [`static/app.js`](../static/app.js); [`static/js/`](../static/js/); [`static/style.css`](../static/style.css); [`app.py`](../app.py) deep-link handlers.
+
+- **Known problems:** The `/backgrounds` route in [`app.py`](../app.py) calls `serve_html_with_nonce` for `static/backgrounds.html`, but that file is absent from [`static/`](../static/). This is a confirmed broken prototype route, not evidence about the rest of the frontend.
+
+- **Open question:** Is `/backgrounds` currently an intentionally supported route or an obsolete prototype?
+
+## Chat, sessions, and streaming
+
+- **How it works:** [`routes/chat_routes.py`](../routes/chat_routes.py) and [`routes/chat_helpers.py`](../routes/chat_helpers.py) coordinate requests, session state, and SSE delivery. [`src/chat_handler.py`](../src/chat_handler.py), [`src/chat_processor.py`](../src/chat_processor.py), [`src/llm_core.py`](../src/llm_core.py), and [`src/session_actions.py`](../src/session_actions.py) provide message preparation, provider interaction, and session operations.
+
+- **Evidence locations:** [`routes/chat_routes.py`](../routes/chat_routes.py); [`routes/chat_helpers.py`](../routes/chat_helpers.py); [`routes/session_routes.py`](../routes/session_routes.py); [`src/chat_handler.py`](../src/chat_handler.py); [`src/chat_processor.py`](../src/chat_processor.py); [`src/llm_core.py`](../src/llm_core.py); [`core/session_manager.py`](../core/session_manager.py).
+
+- **Known problems:** [`src/agent_loop.py`](../src/agent_loop.py) annotates `_resolved_tool_event_name` with `Any` but imports no `Any` and does not enable postponed annotation evaluation. Python evaluates that annotation while importing the module, so this is an import-time defect at the checked baseline.
+
+- **Open question:** No end-to-end provider or browser streaming run was performed for this map.
+
+## Agents, tools, and execution
+
+- **How it works:** [`src/agent_loop.py`](../src/agent_loop.py) drives multi-round tool use. [`src/tool_execution.py`](../src/tool_execution.py) dispatches calls and binds workspace context. [`src/agent_tools/`](../src/agent_tools/) contains individual implementations; [`src/tool_security.py`](../src/tool_security.py) and [`src/tool_policy.py`](../src/tool_policy.py) apply role and request policies. Long-running command work is represented by [`src/bg_jobs.py`](../src/bg_jobs.py).
+
+- **Evidence locations:** [`src/agent_loop.py`](../src/agent_loop.py); [`src/tool_execution.py`](../src/tool_execution.py); [`src/agent_tools/`](../src/agent_tools/); [`src/tool_security.py`](../src/tool_security.py); [`src/tool_policy.py`](../src/tool_policy.py); [`src/tool_schemas.py`](../src/tool_schemas.py); [`src/bg_jobs.py`](../src/bg_jobs.py).
+
+- **Known problems:** The import-time annotation defect above blocks the main agent/tool path. The shell is intentionally not a filesystem or network sandbox; that is an authority boundary, not by itself a vulnerability claim.
+
+- **Open question:** Which native, legacy, and MCP-qualified invocation paths reach each policy gate?
+
+## Models, providers, and local serving
+
+- **How it works:** Model routes delegate to discovery, capabilities, endpoint resolution, and LLM core modules. Cookbook routes and hardware-fit services handle model lifecycle and local-serving support.
+
+- **Evidence locations:** [`routes/model_routes.py`](../routes/model_routes.py); [`src/model_discovery.py`](../src/model_discovery.py); [`src/model_capabilities.py`](../src/model_capabilities.py); [`src/endpoint_resolver.py`](../src/endpoint_resolver.py); [`src/llm_core.py`](../src/llm_core.py); [`routes/cookbook_routes.py`](../routes/cookbook_routes.py); [`src/cookbook_serve_lifecycle.py`](../src/cookbook_serve_lifecycle.py); [`services/hwfit/`](../services/hwfit/).
+
+- **Known problems:** None recorded by this mapping.
+
+- **Open question:** Which endpoint inputs are administrator-created and permitted to use private provider addresses?
+
+## Search and research
+
+- **How it works:** HTTP search routes use [`services/search/`](../services/search/); research is exposed through [`routes/research/`](../routes/research/) and implemented in [`services/research/`](../services/research/), [`src/deep_research.py`](../src/deep_research.py), and related helpers. [`src/search/`](../src/search/) remains an import-compatibility layer for callers not yet moved to `services.search`.
+
+- **Evidence locations:** [`routes/search_routes.py`](../routes/search_routes.py); [`services/search/`](../services/search/); [`routes/research/research_routes.py`](../routes/research/research_routes.py); [`services/research/`](../services/research/); [`src/deep_research.py`](../src/deep_research.py); [`src/search/`](../src/search/).
+
+- **Known problems:** None recorded by this mapping.
+
+- **Open question:** No live provider request was made; provider configuration and network access remain unverified.
+
+## Documents, retrieval, and personal knowledge
+
+- **How it works:** Document routes coordinate upload handling, document processing, and editor actions. Personal-document and RAG modules use Chroma and embedding clients. PDF viewing uses the optional-dependency loader in [`src/pdf_runtime.py`](../src/pdf_runtime.py); form extraction and filling live separately in [`src/pdf_forms.py`](../src/pdf_forms.py) and [`src/pdf_form_doc.py`](../src/pdf_form_doc.py).
+
+- **Evidence locations:** [`routes/document_routes.py`](../routes/document_routes.py); [`src/upload_handler.py`](../src/upload_handler.py); [`src/document_processor.py`](../src/document_processor.py); [`src/document_actions.py`](../src/document_actions.py); [`src/personal_docs.py`](../src/personal_docs.py); [`src/rag_manager.py`](../src/rag_manager.py); [`src/embeddings.py`](../src/embeddings.py); [`src/pdf_runtime.py`](../src/pdf_runtime.py); [`src/pdf_forms.py`](../src/pdf_forms.py); [`src/pdf_form_doc.py`](../src/pdf_form_doc.py).
+
+- **Known problems:** PDF viewing/runtime loading and PDF form processing are separate implementations. That separation is confirmed and intentional in the source; it is not a defect without a reported behavioural failure.
+
+- **Open question:** Optional PDF dependencies and representative uploaded documents were not exercised.
+
+## Memory and skills
+
+- **How it works:** Memory routes use [`services/memory/`](../services/memory/) and vector helpers. Skills are exposed through [`routes/skills_routes.py`](../routes/skills_routes.py), stored and managed in [`services/memory/skills.py`](../services/memory/skills.py), and may be imported through [`services/memory/skill_importer.py`](../services/memory/skill_importer.py).
+
+- **Evidence locations:** [`routes/memory/memory_routes.py`](../routes/memory/memory_routes.py); [`services/memory/`](../services/memory/); [`src/memory.py`](../src/memory.py); [`src/memory_vector.py`](../src/memory_vector.py); [`routes/skills_routes.py`](../routes/skills_routes.py); [`services/memory/skills.py`](../services/memory/skills.py); [`services/memory/skill_importer.py`](../services/memory/skill_importer.py).
+
+- **Known problems:** None recorded by this mapping.
+
+- **Open question:** Which imported skill content can reach execution-capable paths, and which validation occurs before that point?
+
+## Email, calendar, contacts, notes, and tasks
+
+- **How it works:** Dedicated route modules own email, CalDAV calendar, CardDAV contacts, notes, and tasks. Supporting modules include email helpers and pollers, CalDAV sync and writeback, and the task scheduler.
+
+- **Evidence locations:** [`routes/email_routes.py`](../routes/email_routes.py); [`routes/calendar_routes.py`](../routes/calendar_routes.py); [`routes/contacts/contacts_routes.py`](../routes/contacts/contacts_routes.py); [`routes/note/note_routes.py`](../routes/note/note_routes.py); [`routes/task_routes.py`](../routes/task_routes.py); [`routes/assistant_routes.py`](../routes/assistant_routes.py); [`src/caldav_sync.py`](../src/caldav_sync.py); [`src/caldav_writeback.py`](../src/caldav_writeback.py); [`src/task_scheduler.py`](../src/task_scheduler.py).
+
+- **Known problems:** None recorded by this mapping.
+
+- **Open question:** External account behaviour, writeback, and delivery require controlled credentials and are not runtime-validated here.
+
+## Media, speech, and image work
+
+- **How it works:** Gallery and image routes coordinate media features. Service modules own speech and media integrations; [`src/generated_images.py`](../src/generated_images.py) and [`src/visual_report.py`](../src/visual_report.py) support artifact handling and presentation.
+
+- **Evidence locations:** [`routes/gallery/gallery_routes.py`](../routes/gallery/gallery_routes.py); [`routes/stt_routes.py`](../routes/stt_routes.py); [`routes/tts_routes.py`](../routes/tts_routes.py); [`src/generated_images.py`](../src/generated_images.py); [`services/stt/`](../services/stt/); [`services/tts/`](../services/tts/); [`services/faces/`](../services/faces/); [`src/visual_report.py`](../src/visual_report.py).
+
+- **Known problems:** None recorded by this mapping.
+
+- **Open question:** Hardware- and provider-dependent media workflows were not exercised.
+
+## Authentication, secrets, and privileged administration
+
+- **How it works:** [`core/auth.py`](../core/auth.py) and [`core/middleware.py`](../core/middleware.py) provide identity and request gates. [`src/secret_storage.py`](../src/secret_storage.py) encrypts application-managed database secrets with a local Fernet key. Vault handling is separate: [`routes/vault_routes.py`](../routes/vault_routes.py) and [`src/tools/vault.py`](../src/tools/vault.py) invoke the Bitwarden CLI and persist its session data in the application data area.
+
+- **Evidence locations:** [`core/auth.py`](../core/auth.py); [`core/middleware.py`](../core/middleware.py); [`routes/auth_routes.py`](../routes/auth_routes.py); [`routes/api_token_routes.py`](../routes/api_token_routes.py); [`src/secret_storage.py`](../src/secret_storage.py); [`routes/vault_routes.py`](../routes/vault_routes.py); [`src/tools/vault.py`](../src/tools/vault.py); [`routes/admin_wipe/admin_wipe_routes.py`](../routes/admin_wipe/admin_wipe_routes.py).
+
+- **Known problems:** Vault-command handling and local application secret storage are distinct paths with different storage mechanisms. This is a source-confirmed boundary, not evidence that either path is compromised.
+
+- **Open question:** What are the current confidentiality, ownership, rotation, and backup semantics for vault session data?
+
+## Persistence, background work, and operations
+
+- **How it works:** SQLite models and persistence are centred in [`core/database.py`](../core/database.py); managers use application data paths. The scheduler and background-job monitor can continue work outside a live browser request. Operational routes cover cleanup, backup, and administrative wipe; the repository also provides a backup script and user documentation.
+
+- **Evidence locations:** [`core/database.py`](../core/database.py); [`src/runtime_paths.py`](../src/runtime_paths.py); [`src/task_scheduler.py`](../src/task_scheduler.py); [`src/bg_jobs.py`](../src/bg_jobs.py); [`src/bg_monitor.py`](../src/bg_monitor.py); [`routes/backup_routes.py`](../routes/backup_routes.py); [`routes/cleanup/cleanup_routes.py`](../routes/cleanup/cleanup_routes.py); [`routes/admin_wipe/admin_wipe_routes.py`](../routes/admin_wipe/admin_wipe_routes.py); [`scripts/odysseus-backup`](../scripts/odysseus-backup); [`docs/backup-restore.md`](../docs/backup-restore.md).

+
+> [!NOTE]
+> This document is the proposed canonical destination for stable high-level
+> architecture facts. It remains subject to maintainer review. Source code,
+> tests, and configuration remain authoritative for implementation-sensitive
+> behaviour.
+
+## Purpose
+
+This document identifies the stable runtime boundaries and primary ownership
+locations used to navigate and extend Odysseus.
+
+It intentionally excludes generated metrics, file-size rankings, refactor
+priorities, unresolved investigation findings, and proposed package layouts.
+
+## Runtime structure
+
+| Area | Responsibility |
+|---|---|
+| `app.py` | FastAPI application composition and primary application entry point |
+| `launcher.py` | Application launch support |
+| `setup.py` | Native setup workflow |
+| `core/` | Authentication, middleware, persistence, sessions, and platform primitives |
+| `routes/` | HTTP and API route handlers |
+| `src/` | Application orchestration, tools, providers, and runtime helpers |
+| `services/` | Domain-oriented service implementations |
+| `mcp_servers/` | Built-in MCP server implementations |
+| `scripts/` | CLI tools, diagnostics, maintenance, and migration helpers |
+| `static/` | No-build browser frontend and bundled assets |
+| `tests/` | Automated tests and supporting test infrastructure |
+
+## Subsystem boundaries
+
+| Subsystem | Primary implementation locations |
+|---|---|
+| Application startup | `app.py`, `src/app_initializer.py`, `core/` |
+| Authentication and sessions | `core/auth.py`, `core/middleware.py`, `core/session_manager.py`, `routes/auth_routes.py` |
+| Chat and streaming | `routes/chat_routes.py`, `routes/chat_helpers.py`, `src/chat_handler.py`, `src/chat_processor.py`, `src/llm_core.py` |
+| Agents and tools | `src/agent_loop.py`, `src/tool_execution.py`, `src/agent_tools/`, `src/tools/`, `src/tool_policy.py`, `src/tool_security.py` |
+| Models and providers | `routes/model_routes.py`, `src/model_discovery.py`, `src/model_capabilities.py`, `src/endpoint_resolver.py`, `src/llm_core.py` |
+| Cookbook and hardware fit | `routes/cookbook_routes.py`, `routes/cookbook_helpers.py`, `src/cookbook_serve_lifecycle.py`, `services/hwfit/` |
+| Search and research | `routes/search_routes.py`, `services/search/`, `routes/research/`, `services/research/`, `src/deep_research.py` |
+| Documents and retrieval | `routes/document_routes.py`, `src/document_processor.py`, `src/personal_docs.py`, `src/rag_manager.py`, `src/pdf_runtime.py` |
+| Memory and skills | `routes/memory/`, `services/memory/`, `routes/skills_routes.py` |
+| Email | `routes/email_routes.py`, `routes/email_helpers.py`, `routes/email_pollers.py`, `mcp_servers/email_server.py` |
+| Calendar, contacts, notes, and tasks | `routes/calendar_routes.py`, `routes/contacts/`, `routes/note/`, `routes/task_routes.py`, `src/task_scheduler.py` |
+| Media and speech | `routes/gallery/`, `routes/stt_routes.py`, `routes/tts_routes.py`, `services/stt/`, `services/tts/` |
+| Persistence and operations | `core/database.py`, `src/runtime_paths.py`, `src/bg_jobs.py`, `routes/backup_routes.py`, `routes/cleanup/` |
+
+## Architectural constraints
+
+- Preserve established import and compatibility paths unless a focused change
+  explicitly migrates them.
+- Keep HTTP concerns in route modules and reusable domain behaviour in runtime
+  or service modules.
+- Treat shared persistence, agent orchestration, tool execution, and application
+  startup as high-authority boundaries.
+- Change one ownership boundary at a time.
+- Do not mix structural movement with unrelated feature behaviour.
+- Validate affected imports, startup paths, compatibility surfaces, and tests.
+
+## Frontend
+
+The browser frontend is a no-build ES-module application under `static/`.
+
+Its maintained module-level structure is documented in
+[`static/js/MODULE_SUMMARY.md`](../static/js/MODULE_SUMMARY.md).
+
+## Investigation and snapshots
+
+Non-canonical investigation material is maintained under [`discovery/`](../discovery/).
+
+The following documents may contain dated observations, metrics, unresolved
+questions, or historical planning and must not be treated as specifications:
+
+- [`discovery/system-map.md`](../discovery/system-map.md)
+- [`discovery/architecture-runtime-inventory.md`](../discovery/architecture-runtime-inventory.md)
+
+## Documentation authority
+
+- Code, tests, and configuration define implemented behaviour.
+- Mature specifications define accepted subsystem behaviour where they exist.
+- Following maintainer acceptance, this document will define the high-level
+  architecture map.
+- Discovery documents preserve evidence and uncertainty but remain
+  non-canonical.

+# Documentation style
+
+This guide defines the shared structure and writing conventions for Odysseus documentation.
+
+## Principles
+
+- Write for a clear audience and purpose.
+- State whether a document is canonical, informational, a snapshot, or planning material.
+- Prefer current behaviour over historical explanation.
+- Link to source files, tests, issues, or other documentation when useful.
+- Separate verified behaviour from assumptions, open questions, and future work.
+- Keep headings descriptive and consistent.
+- Use Markdown callouts where status or risk must be visible.
+- Do not use emojis.
+
+## Document status
+
+Use a status callout near the top when the document is not normal canonical guidance.
+
+### Canonical documentation
+
+> [!IMPORTANT]
+> This document describes accepted current behaviour. Verify implementation-sensitive details against the current code and tests.
+
+### Discovery material
+
+> [!NOTE]
+> This is non-canonical discovery material. It records code-grounded observations and open questions.
+
+### Snapshot or inventory
+
+> [!WARNING]
+> This document is a dated snapshot. Counts, paths, and implementation details may drift as the codebase changes.
+
+### Planning material
+
+> [!NOTE]
+> This document records planning context. It does not define current runtime behaviour or guarantee future implementation.
+
+## Recommended structure
+
+Use the following sections where relevant:
+
+1. Title
+2. Purpose or status callout
+3. Scope
+4. Current behaviour or guidance
+5. Safety, limitations, or known gaps
+6. Validation or evidence
+7. Related documentation
+
+Not every document needs every section.
+
+## Writing style
+
+- Use concise sentences.
+- Prefer direct language.
+- Avoid jokes, filler, and informal warnings.
+- Avoid repeating the same guidance across several files.
+- Link to the owning document instead of duplicating large sections.
+- Use lists for procedures, requirements, and comparisons.
+- Use tables only when they improve scanning.
+- Use fenced code blocks with an appropriate language identifier.
+- Use relative repository links for internal files.
+
+## Authority
+
+The current code, tests, and configuration are the source of truth for implemented behaviour.
+
+Canonical documentation describes accepted behaviour and supported workflows.
+
+Discovery, inventory, and planning documents must identify themselves explicitly and must not silently become behavioural specifications.

-# Architecture Runtime Inventory
-
-> **Purpose**: Phase 0 planning baseline for codebase readability improvements (#4071).
-> **Parent issue**: [#4082](https://github.com/odysseus-dev/odysseus/issues/4082)
-> **Last updated**: dev@b58af42 | 2026-06-16
-> **Status**: Draft — to be reviewed before follow-up slices open.
-> **Snapshot basis**: Importer / file / import-line counts are refreshed to `dev@b58af42` (2026-06-16) and are recomputable via the commands in §3.4. **Line counts** in §2.1 / §2.2 are a snapshot from an earlier baseline and drift as `dev` moves — recompute any of them with `wc -l <file>`. This inventory tracks structure and risk, not live metrics.
-
-This document maps the current runtime module structure, identifies high-risk boundaries, and recommends safe first refactor slices. It does **not** move files, change imports, or alter runtime behavior.

-### 1.2 Directory Flatness Metric
-
-| Directory | Flat `.py` Files | Subdirectories | Concern |
-|-----------|-----------------|----------------|---------|
-| `src/` | **95** | 2 (`agent_tools/`, `search/`) | No domain grouping; 95 files in one directory |
-| `routes/` | **54** | 0 | All route handlers in one flat directory |
-| `core/` | 10 | 0 | Manageable, but `database.py` is oversized |
-
----
-
-## 2. Largest Runtime Modules
-
-### 2.1 Python Backend
-
-| Rank | File | Lines | Classes | Functions | Risk |
-|------|------|-------|---------|-----------|------|
-| 1 | `src/tool_implementations.py` | **4,032** | 0 | ~48 | **HIGH** |
-| 2 | `routes/email_routes.py` | **3,245** | — | — | **MEDIUM** |
-| 3 | `routes/cookbook_routes.py` | **2,969** | — | — | **MEDIUM** |
-| 4 | `src/agent_loop.py` | **2,961** | 0 | ~24 | **HIGH** |
-| 5 | `src/task_scheduler.py` | **2,330** | — | 5 | MEDIUM |
-| 6 | `routes/model_routes.py` | **2,266** | — | — | MEDIUM |
-| 7 | `core/database.py` | **2,265** | 28 | ~59 helpers | **HIGH** |
-| 8 | `src/builtin_actions.py` | **2,262** | 2 | ~24 | MEDIUM |
-| 9 | `src/llm_core.py` | **2,164** | — | — | MEDIUM |
-| 10 | `mcp_servers/email_server.py` | 2,197 | — | — | LOW (separate process) |
-| 11 | `src/visual_report.py` | 1,918 | — | — | LOW |
-| 12 | `routes/gallery_routes.py` | 1,896 | — | — | LOW |
-| 13 | `src/ai_interaction.py` | 1,846 | — | — | MEDIUM |
-| 14 | `routes/document_routes.py` | 1,717 | — | — | LOW |
-| 15 | `routes/skills_routes.py` | 1,648 | — | — | LOW |
-
-**Heuristic**: Files > 2,000 lines with 20+ public symbols and many importers are the highest-risk splits. Files 1,000–2,000 lines are medium-risk if tightly coupled.
-
-### 2.2 Frontend
-
-| File | Lines | Concern |
-|------|-------|---------|
-| `static/style.css` | **36,653** | Entire app CSS in one file (tracked separately in #2617) |
-| `static/js/document.js` | **9,776** | Single JS file for document functionality |
-| `static/js/slashCommands.js` | 6,498 | |
-| `static/js/settings.js` | 5,266 | |
-| `static/js/emailLibrary.js` | 5,217 | |
-| `static/js/notes.js` | 5,124 | |
-| `static/js/chat.js` | 4,985 | |
-| `static/app.js` | 4,090 | |
-
-**Note**: Frontend modularization is tracked separately in #2617 (CSS) and is not the focus of this Phase 0 inventory. Frontend is listed here for completeness but follow-up slices should target Python backend boundaries first.

-## 3. Import Dependency Graph
-
-### 3.1 Who Depends on `core/database.py`
-
-**102 files** import from `core.database` — this is the most depended-upon module:
-
-- All route handlers (`routes/*.py`)
-- Most `src/*.py` files
-- `core/session_manager.py`, `core/auth.py`
-- Multiple test files
-
-**Implication**: Any split of `core/database.py` is the highest-risk refactor. It should be tackled **last**, never first.
-
-### 3.2 Who Depends on `src/tool_implementations.py`
-
-**17 files** import from `src.tool_implementations`:
-- `src/agent_loop.py`, `src/builtin_actions.py`, `src/tool_index.py`
-- `src/task_scheduler.py`, `src/tool_policy.py`
-- Various tests
-
-### 3.3 Who Depends on `src/agent_loop.py`
-
-**22 files** import from `src.agent_loop`:
-
-- `src/tool_policy.py`, `src/teacher_escalation.py`, `src/bg_monitor.py`
-- `src/task_scheduler.py`
-- Multiple test files
-
-### 3.4 Cross-Layer Import Violations
-
-**`src/` importing from `routes/`** (backwards dependency — domain logic depending on HTTP layer):
-
-```
-src/tool_implementations.py ──→ routes/calendar_routes.py
-src/tool_implementations.py ──→ routes/cookbook_helpers.py
-src/tool_implementations.py ──→ routes/email_helpers.py
-src/tool_implementations.py ──→ routes/email_pollers.py
-src/tool_implementations.py ──→ routes/email_routes.py
-src/tool_implementations.py ──→ routes/model_routes.py
-src/tool_implementations.py ──→ routes/note_routes.py
-src/tool_implementations.py ──→ routes/prefs_routes.py
-```
-
-> These are **runtime imports** (inside function bodies, not at module top), which mitigates circular import risk but indicates fuzzy layer boundaries. Function-level inline imports from the HTTP layer into business logic are a code smell.
-
-**Import counts (top-level)**:
-| Direction | Count | Notes |
-|-----------|-------|-------|
-| `routes/` → `src/` | **374** | Expected: HTTP handlers call domain logic |
-| `routes/` → `core/` | **126** | Expected: handlers access DB models |
-| `src/` → `routes/` | **31** | **Unexpected**: domain logic reaching into HTTP layer (direct grep of import lines referencing `routes/`) |
-| `src/` → `core/` | **106** | Acceptable but could be reduced with a data-access layer |
-
-> **How the metrics in this document are computed** — recompute against current `dev` before treating any count as authoritative (the tree drifts; these numbers are a snapshot, not a live value):
-> - `src/` flat `.py` files: `find src -maxdepth 1 -name '*.py' | wc -l`
-> - `tests/` test files: `find tests -name 'test_*.py' | wc -l`
-> - `core.database` importers: `grep -rlE '(from|import) +core\.database' --include='*.py' . | grep -v core/database.py | wc -l`
-> - `src.agent_loop` importers: `grep -rlE '(from|import) +src\.agent_loop' --include='*.py' . | grep -v src/agent_loop.py | wc -l`
-> - Cross-layer import lines: `grep -rhE '(from|import) +<pkg>' --include='*.py' <dir>/ | wc -l` (e.g. `(from|import) +routes` over `src/`)
-

-## 4. Route Ownership Map
-
-Routes can be grouped into logical feature domains. Current flat structure obscures these boundaries:
-
-| Domain | Route Files | Total Lines | Review Complexity |
-|--------|-------------|-------------|-------------------|
-| **Email** | `email_routes.py`, `email_helpers.py`, `email_pollers.py` | 5,936 | HIGH — most complex domain |
-| **Chat / Agent** | `chat_routes.py`, `chat_helpers.py`, `shell_routes.py`, `codex_routes.py`, `skills_routes.py` | 6,365 | HIGH — core interaction surface |
-| **Cookbook** | `cookbook_routes.py`, `cookbook_helpers.py`, `cookbook_output.py` | 4,110 | MEDIUM |
-| **Model / LLM** | `model_routes.py`, `assistant_routes.py`, `copilot_routes.py` | 2,764 | MEDIUM |
-| **Calendar / Contacts** | `calendar_routes.py`, `contacts_routes.py` | 2,336 | MEDIUM |
-| **Documents** | `document_routes.py`, `document_helpers.py` | 1,954 | LOW |
-| **Auth** | `auth_routes.py`, `api_token_routes.py`, `device_flow.py` | 1,171 | LOW |
-| **Tasks** | `task_routes.py` (standalone) | 1,157 | LOW |
-| **Session** | `session_routes.py` (standalone) | 1,287 | LOW |
-| **Gallery** | `gallery_routes.py`, `gallery_helpers.py` | 1,896 | LOW |
-| **Memory** | `memory_routes.py` | — | LOW |
-| **Research** | `research_routes.py` | — | LOW |
-| **MCP** | `mcp_routes.py` | — | LOW |
-| **Notes** | `note_routes.py` | — | LOW |
-| **Other** | `prefs_routes.py`, `upload_routes.py`, `vault_routes.py`, `webhook_routes.py`, `workspace_routes.py`, `search_routes.py`, `history_routes.py`, `hwfit_routes.py`, `preset_routes.py`, `signature_routes.py`, `backup_routes.py`, `cleanup_routes.py`, `diagnostics_routes.py`, `embedding_routes.py`, `emoji_routes.py`, `font_routes.py`, `stt_routes.py`, `tts_routes.py`, `compare_routes.py`, `personal_routes.py`, `editor_draft_routes.py`, `admin_wipe_routes.py`, `chatgpt_subscription_routes.py` | 2,000+ | LOW individual, HIGH cumulative |

-## 5. Tool Registry & Implementation Boundaries
-
-### 5.1 Current Tool Architecture
-
-| Component | File | Lines | Role |
-|-----------|------|-------|------|
-| Tool schemas | `src/tool_schemas.py` | 1,392 | JSON Schema tool definitions (Duck-TypedDict) |
-| Tool index | `src/tool_index.py` | 542 | RAG-based tool retrieval from ChromaDB |
-| Tool implementations | `src/tool_implementations.py` | 4,032 | 33 `do_*` functions — all tool execution logic |
-| Tool security | `src/tool_security.py` | — | Owner-scoped tool blocking |
-| Tool policy | `src/tool_policy.py` | — | Guide-only directive, plan-mode disabled tools |
-| Tool utils | `src/tool_utils.py` | — | Shared tool helpers |
-
-### 5.2 Tool Implementation Categories
-
-The 33 `do_*` functions in `tool_implementations.py` fall into natural domain groups — the basis for slice 1's split in §6.2:
-
-| Category | `do_*` functions | Count |
-|----------|------------------|-------|
-| **System / config** | `do_manage_skills`, `do_manage_tasks`, `do_manage_endpoints`, `do_manage_mcp`, `do_manage_webhooks`, `do_manage_tokens`, `do_manage_settings`, `do_api_call`, `do_app_api` | 9 |
-| **Cookbook / model serving** | `do_download_model`, `do_serve_model`, `do_list_served_models`, `do_stop_served_model`, `do_tail_serve_output`, `do_list_downloads`, `do_cancel_download`, `do_search_hf_models`, `do_adopt_served_model`, `do_list_cookbook_servers`, `do_list_serve_presets`, `do_serve_preset`, `do_list_cached_models` | 13 |
-| **Notes** | `do_manage_notes` | 1 |
-| **Calendar** | `do_manage_calendar` | 1 |
-| **Search** | `do_search_chats` | 1 |
-| **Research** | `do_manage_research`, `do_trigger_research` | 2 |
-| **Contacts** | `do_resolve_contact`, `do_manage_contact` | 2 |
-| **Vault** | `do_vault_search`, `do_vault_get`, `do_vault_unlock` | 3 |
-| **Image** | `do_edit_image` | 1 |
-| | **Total** | **33** |
-
-> Low-level tools (filesystem, subprocess, web fetch, document parsing) live in `src/agent_tools/`, **not** in `tool_implementations.py` — out of scope for this split.
-
----
-
-## 6. Risk Assessment & Candidate Slice Ranking
-
-> **Candidate proposals, not a committed plan.** The rankings, package shapes (e.g. `src/pkg/`, `src/domain/`, `src/infra/`, `src/api/`), split ordering, and route-grouping strategy below are **options for maintainer discussion**. Per #4082/#4071, slice ownership and order are settled by maintainers before any follow-up PR. §1–§3 above are the factual current-state inventory.
-
-### 6.1 Risk Scale
-
-| Level | Criteria |
-|-------|----------|
-| **LOW** | File has ≤3 importers AND ≤500 lines, OR is a pure refactor with clear boundaries |
-| **MEDIUM** | File has 4–15 importers OR 500–1,500 lines |
-| **HIGH** | File has 16+ importers OR >2,000 lines, OR has cross-layer import violations |
-
-### 6.2 Ranked Split Candidates
-
-| Priority | Target | Risk | Rationale |

-| **1** | `src/tool_implementations.py` → `src/tools/*.py` | **MEDIUM** | 4,032 lines → ~10 files by tool category. Already has natural boundaries. 17 importers, tracked in #3629. Use `__init__.py` shim to keep existing imports working. |
-| **2** | `routes/` → domain subdirectories (one domain per PR) | **MEDIUM** | 54 flat files. Done **one domain at a time** (e.g. a standalone PR for the email domain, then chat, …), not a broad reorganization — route modules carry helper imports, registration assumptions, and test import paths. |

-### 6.3 Candidate First 3 Behavior-Preserving Slices
-
-**Slice 1: Split `tool_implementations.py`** (Lowest-risk high-impact)
-
-- Create `src/tools/` package with one file per tool category
-- Add `src/tools/__init__.py` re-exporting all symbols with current names
-- Update 17 importers to use new paths (can be deferred via shim)
-- Validation: `python -m pytest tests/ -x -q` + manual smoke test of tool execution
-- Reference: #3629
-
-**Slice 2: Group `routes/` by domain** (one domain per PR, not a broad sweep)
-
-Route modules carry helper imports, router registration assumptions, and test import paths, so this must be done **one domain at a time** rather than as a single reorganization PR. Example sequence (each its own PR):
-
-- PR 2a: move the **email** domain (`email_routes.py`, `email_helpers.py`, `email_pollers.py`) → `routes/email/` + shim
-- PR 2b: move the **chat/agent** domain → `routes/chat/` + shim
-- PR 2c: move the **cookbook** domain → `routes/cookbook/` + shim
-- …and so on per domain from §4
-
-Each PR: add `__init__.py` re-exporting old names, update `app.py` router imports, validation `python app.py` starts clean. **No behavior change** — pure file reorganization.
-
-**Slice 3: Extract `agent_loop.py` submodules** (Improve reviewability)
-
-- Move prompt assembly → `src/agent/prompt.py`
-- Move request classification → `src/agent/classifier.py`
-- Move sub-agent verification → `src/agent/verifier.py`
-- Move runaway detection → `src/agent/runaway.py`
-- Move context management → `src/agent/context.py`
-- Keep `src/agent/loop.py` as the main orchestration module
-- Validation: `python -m pytest tests/test_agent_loop.py tests/test_loop_breaker_runaway.py -v`
-

-
-## 7. Safety Guardrails for Follow-Up Work
-
-Per maintainer guidance in #4082 and #4071:
-
-- [ ] **One domain/slice per PR** — never mix multiple reorganizations
-- [ ] **No behavior changes** mixed with file moves — pure reorganization only
-- [ ] **Keep compatibility shims** — `__init__.py` re-exports for all existing import paths
-- [ ] **Add or identify focused tests** before risky splits
-- [ ] **Do not start with `core/database.py`** or broad route movement unless this inventory shows a safe boundary
-- [ ] **Prefer small, reviewable slices** over large restructures
-- [ ] **No packaging/runtime/tooling migration** mixed into file moves
-- [ ] **No frontend framework migration** inside this stabilization lane
-- [ ] **Validate with `python -m compileall`** — every PR must pass CI checks
-- [ ] **Validate with `pytest`** — run the full test suite before opening each PR
-
----
-
-## 8. Validation Commands
-
-Each follow-up PR should be verifiable with these commands before submission:
-
-```bash
-# Syntax check — must pass with zero errors
-python -m compileall src/ routes/ core/ conf/
-
-# Full test suite — must match baseline pass rate
-python -m pytest tests/ -x -q
-
-# Import shim verification — existing import paths must still work
-python -c "from src.tool_implementations import do_search_chats; print('OK')"
-
-# App startup smoke test (if backend touched)
-timeout 5 python app.py 2>&1 | head -5 || true
-```
-
----
-
-## 9. Open Questions
-
-1. Is `#2538` (specs ground truth) the canonical behavior map baseline, and should this inventory be kept in sync with those specs once merged?
-2. Should route grouping follow the domain map proposed here, or is there a different taxonomy preferred by maintainers?
-3. For the `tool_implementations.py` split (#3629), is the tool categorization in §5.2 acceptable, or should it follow a different grouping?
-4. Should compatibility shims (`__init__.py`) be temporary (removed in a follow-up wave) or permanent?
-5. Should an ADR (Architecture Decision Record) document be started to track decisions made during this process?
-
----
-
-## 10. Future Direction (NOT current state)
-
-The following are **future refactor targets** (candidate directions **pending maintainer agreement**, not committed), recorded here so this inventory does not imply they exist today. None of them are present in the current `dev` tree:
-
-- `main.py` — proposed rename of the `app.py` entrypoint. Today the app boots via `app.py`.
-- `src/agent/` — proposed package to hold `agent_loop.py` submodules (prompt/classifier/verifier/runaway/context). Today `agent_loop.py` is a single flat file in `src/`.
-- `src/infra/`, `src/domain/`, `src/pkg/`, `src/api/` — proposed layered reorganization of the flat `src/` directory (slice 4 in §6).
-
-These become real only when the corresponding slices land.

-# Test Layout Inventory
+# Test layout inventory
+
+> [!NOTE]
+> This document is a completed implementation snapshot for the first low-risk
+> test-directory reorganization. It does not propose additional file moves and
+> is not the canonical definition of the current test taxonomy.
+
+- **Original inventory:** #3712
+- **Parent tracker:** #2523
+- **Implemented by:** #3842
+- **Status:** completed historical snapshot
+
+- **Durable testing policy:** [`TESTING_STANDARD.md`](./TESTING_STANDARD.md)
+- **Current testing mechanics:** [`README.md`](./README.md)
+
+## Disposition
+
+This document is retained as a non-canonical historical record of the completed
+CLI test relocation.
+
+Reusable testing rules are maintained in `TESTING_STANDARD.md`; current helper,
+taxonomy-runner, and execution mechanics are maintained in `README.md`, the test
+suite, and its supporting code.
+
+Counts, residual-file observations, and path listings in this document are
+snapshot evidence only. They must not be maintained as durable repository truth.
+
+Any additional test relocation requires a separately approved issue or work item.
 
 ## Purpose
 
-Inventory for the first low-risk split of the flat `tests/` directory
-(issue #3712, parent #2523). This document only records *what* should move
-first and *why*; it moves nothing. The actual move is a separate, mechanical
-PR that relocates the listed files verbatim and changes no test content.
+This document preserves the reasoning, scope, and validation contract for the
+first mechanical reorganization of the formerly flat `tests/` directory.
 
-The target layout and category definitions come from
-[`TESTING_STANDARD.md`](./TESTING_STANDARD.md); the collection-time markers
-come from [`_taxonomy.py`](./_taxonomy.py), which classifies by **filename
-tokens only** (paths are ignored, except the `tests/helpers/` rule). A file
-keeps its `area_*`/`sub_*` markers when moved into a subdirectory, and
-`conftest.py` discovers marker names recursively (`rglob`), so a move does not
-disturb marker registration or focused selection.
+The original change moved 28 tests classified as `area_cli` into `tests/cli/`
+without changing their assertions, helpers, taxonomy, or runtime behaviour.
 
-## Current low-risk candidate groups
+Current testing guidance and classification rules are maintained in:
 
-Groups whose tests need no route/app setup and no real DB/session setup:
+- [`README.md`](./README.md)
+- [`TESTING_STANDARD.md`](./TESTING_STANDARD.md)
+- [`_taxonomy.py`](./_taxonomy.py)
 
-1. **CLI / script tests** (`area_cli`, 28 files) - load `scripts/` entry
-   points via `tests.helpers.cli_loader.load_script`; DB access is stubbed
-   with `tests.helpers.db_stubs` (`SessionLocal` is a plain stub attribute).
-   No `TestClient`, no FastAPI app import, no SQLite files.
-2. **Helper self-tests** (`area_helpers`) - e.g. `test_helpers_import_state.py`,
-   `test_db_stubs_helper.py`. Safe but tiny (two files), and they test the
-   shared helpers from the #3685 audit (merged) that the rest of the suite
-   depends on; little payoff as a first slice.
-3. **Pure unit / parsing tests** (`area_unit`) - `*_nonstring.py`,
-   `*_nondict.py`, parsing tests. Large and heterogeneous; some touch
-   provider/session modules, so the boundary is less crisp.
-4. **Static checks** - e.g. `test_readme_ascii_fenced.py`,
-   `test_docs_no_orphan_images.py`. Safe but tiny and `uncategorized` in the
-   taxonomy, so a move buys little and matches no existing marker.
+The current repository and test suite remain authoritative when this snapshot
+and the implementation differ.
 
-Not candidates for the first move (per #3712 guidance): security/owner-scope
-tests, route/API tests, DB/session-heavy tests, auth/session concurrency
-tests, and the taxonomy/runner infrastructure tests that changed recently
-(#3491, #3556, #3659, #3711).
+## Why CLI tests were selected
 
-## Recommended first move
+The CLI and script tests were selected as the first low-risk group because they
+formed a narrow, mechanically identifiable boundary:
 
-**CLI / script tests → `tests/cli/`**
+- script entry points were loaded through shared CLI helpers;
+- database access used controlled stubs rather than persistent sessions;
+- the tests did not require FastAPI application or route setup;
+- the tests did not require a real database;
+- taxonomy classification could be derived consistently from filenames;
+- absolute helper imports remained valid after relocation.
 
-Why this group over the alternatives:
+This reduced the risk relative to route, security, session, provider, and
+heterogeneous unit-test groups.
 
-- Lowest coupling: every file imports only the script under test (via
-  `cli_loader`) plus `tests.helpers` stubs - no app, no routes, no real DB.
-- Crisp, machine-checkable boundary: the set is exactly the files classified
-  `area_cli` by `_taxonomy.py`, so before/after selection counts can be
-  compared mechanically.
-- Already the planned target dir for this category in `TESTING_STANDARD.md`
-  (`tests/cli/`).
-- Absolute imports (`from tests.helpers...`) and unique basenames mean no
-  import-order or module-name collisions after the move.
-- Lower risk than helper self-tests (tiny group, little payoff), unit tests
-  (fuzzy boundary), or anything security/route/session-shaped.
+## Completed implementation
 
-## Files included in the first move
+Repository history records the implementation as:
 
-The 28 files classified `area_cli` (verified against `_taxonomy.py`):
+- `83af3ca test: move area_cli tests into cli directory (#3842)`
 
-Note: this inventory was refreshed against current `dev` after `tests/test_research_cli_status.py` was added to the `area_cli` set.

-## Files intentionally excluded
+## Original exclusions
 
-- `tests/test_backup_cli_security.py` - classifies as `area_security`
-  (security outranks cli in the taxonomy); moving it into `tests/cli/` would
-  make the directory disagree with its marker. It belongs with the security
-  group in a later phase.
-- `tests/test_run_focus.py`, `tests/test_taxonomy.py` - taxonomy/runner
-  infrastructure tests, recently changed (#3556, #3659); they also pin
-  flat-layout paths (e.g. `tests/test_auth_config_lock_concurrency.py` in
-  `test_run_focus.py`), so they stay put.
-- Script-like but `uncategorized` files - `test_pr_blocker_audit.py`,
-  `test_update_database_script.py`, `test_windows_update_script.py`,
-  `test_setup_admin_user.py`, `test_amd_gpu_check_args.py`, `test_hwfit_*.py`.
-  They exercise `scripts/` too, but moving them would make `tests/cli/`
-  diverge from the `area_cli` marker set. Reclassify or move them in a later,
-  separate slice.
-- Everything else (security, routes, services, unit, js, helpers) - out of
-  scope for the first move by design.
+The original inventory deliberately excluded:
 
-## How this was verified
+- `tests/test_backup_cli_security.py`, because its security classification
+  outranked the CLI token in its filename;
+- taxonomy and focused-runner infrastructure, including
+  `tests/test_taxonomy.py` and `tests/test_run_focus.py`;
+- script-oriented tests not classified as `area_cli`;
+- route, service, security, session, JavaScript, helper, and broad unit-test
+  groups.
 
-Read-only checks, run from the repo root on this branch. Note the real API is
-`classify_test_path` (there is no `classify_test_file`).
+These exclusions kept the implementation mechanical and prevented it from
+mixing taxonomy changes, assertion changes, helper extraction, or unrelated
+test-suite restructuring.
+
+## Current repository observation
+
+The current taxonomy classifies 30 files as `area_cli`:
+
+| Location | Files |
+|---|---:|
+| `tests/cli/` | 28 |
+| Flat `tests/` directory | 2 |
+
+The two currently classified CLI tests outside `tests/cli/` are:
+
+- `tests/test_calendar_cli_overlap.py`
+- `tests/test_memory_cli_add_nondict.py`
+
+These files were not part of the original 28-file implementation.
+
+Their presence is recorded solely to keep this snapshot accurate. This
+documentation update does not recommend moving them, changing their taxonomy,
+or opening implementation work. Any future test-layout change requires separate
+maintainer agreement, scope, and validation.
+
+## Validation contract preserved by the original move
+
+The completed implementation was designed to preserve:
+
+- identical `area_cli` selection before and after relocation;
+- successful direct execution of the relocated tests;
+- successful whole-suite collection;
+- unchanged taxonomy and focused-runner behaviour;
+- no stale references to the former flat paths;
+- no production-code changes.
+
+Relevant current verification commands include:
 
 ```bash
-# Compute the area_cli set and confirm test_backup_cli_security.py is
-# area_security. Expected: 28 files, then "security".
-./venv/bin/python - <<'PY'

-Also checked by reading the code: `tests/conftest.py` registers sub-markers
-from a recursive `rglob` scan, and `tests/_taxonomy.py` classifies by filename
-tokens only (plus the `tests/helpers/` directory rule), so the markers of the
-28 files do not change when they move into `tests/cli/`.
-
-## Validation for the future move PR
-
-Run with the project venv (`./venv/bin/python`); system `python3` may miss
-pinned deps. Before the move, record the baseline; after, compare:
-
-```bash
-# Selection must match the 28 files before and after the move.
-./venv/bin/python tests/run_focus.py --dry-run --area cli
-./venv/bin/python -m pytest -m area_cli -q
-
-# Moved files pass when targeted directly.

-
-# Whole-suite collection still succeeds (catches import/path breakage).

-
-# Taxonomy/runner infrastructure is unaffected.
-./venv/bin/python -m pytest tests/test_taxonomy.py tests/test_run_focus.py -q
-
-# No stale flat-path references to the moved files. Expected: no matches
-# outside tests/cli/ itself.

-rg -n -F -f /tmp/area_cli_paths.txt .github scripts docs \

-
-Pass criteria: identical test counts for `-m area_cli` before/after, zero
-collection errors, and no changes outside the moved files.
+These commands describe validation coverage. This snapshot does not claim that
+they were executed as part of the present documentation update.
 
 ## Non-goals
 
-- No file moves, renames, or deletions in this PR.
-- No changes to `conftest.py`, `_taxonomy.py`, `run_focus.py`, helpers,
-  markers, CI workflows, or production code.
-- No recommendation to split the whole suite at once; later groups get their
-  own inventory-then-move slices.
+This document does not:
+
+- propose moving or renaming tests;
+- redefine taxonomy classifications;
+- change test behaviour or assertions;
+- prescribe the next test-suite refactor;
+- replace the testing standard;
+- create implementation work from the two current residual files.
