+4. Under **Code scanning**, you have two ways to scan the app code with CodeQL:

-# Architecture Runtime Inventory
-
-> **Purpose**: Phase 0 planning baseline for codebase readability improvements (#4071).
-> **Parent issue**: [#4082](https://github.com/pewdiepie-archdaemon/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** |

-| 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. |
-| **3** | `src/agent_loop.py` → `src/agent/loop.py` + submodules | **MEDIUM-HIGH** | 2,961 lines, 24 functions. Can extract prompt building, classification, verification, and runaway detection. Tracked in #3266. |
-| **4** | `src/` → `src/pkg/`, `src/domain/`, `src/infra/`, `src/api/` | **MEDIUM** | Structural reorganization. Split flat `src/` into layered packages. Must come after routes and tools are stable. |
-| **5** | `routes/email_*.py` consolidation | **LOW** | Already grouped by filename prefix. Low-risk cleanup within the email domain. |
-| **6** | `core/database.py` → `src/infra/database/models/*.py` | **HIGH** | 28 classes, 102 importers. Highest-risk split. Must be **last** in any sequence. Requires careful import shim strategy. |
-| **7** | Frontend CSS modularization | **MEDIUM** | 36,653 lines. Tracked in #2617. Separate timeline from backend work. |
-| **8** | Frontend JS modularization | **MEDIUM** | 9,776 lines in `document.js`. Introduce ES modules at minimum. |
-
-### 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.
