Subject: [PATCH 002/187] refactor(tests): finish shared CLI loader adoption

Test-only refactor continuing #2523. Replaces remaining obvious CLI/script loader boilerplate with tests.helpers.cli_loader.load_script while preserving existing stubs and assertions.

+"""Shared helper for saving and restoring Python import state in tests.
+
+Use ``preserve_import_state`` as a context manager around any block that needs
+to mutate ``sys.modules`` or parent-package attributes temporarily. On exit
+(normal or exception), every named module is restored to exactly the state it
+had before the block — present, absent, or carrying a parent-package attribute.
+
+Use ``clear_module`` to drop a single module from both ``sys.modules`` and its
+parent-package attribute (e.g. before forcing a fresh import inside the block).
+
+Background: importing ``routes.session_routes`` also sets ``session_routes`` on
+the parent ``routes`` package object. A ``from routes import session_routes``
+or ``import routes.session_routes as X`` statement resolves through that parent
+attribute, so restoring ``sys.modules`` alone is not sufficient — the parent
+attribute must be restored too. This helper handles both.
+
+Restoration in ``preserve_import_state`` is two-phased: all ``sys.modules``
+entries are written back first, then all parent-package attributes. This means
+parent-attr restoration always resolves the parent through the already-restored
+``sys.modules``, so results are deterministic regardless of argument order —
+safe for callers that pass both a parent package and a child module.

Subject: [PATCH 006/187] Word-boundary match for snippet and subject-term
 ranking (#1473 follow-up) (#2556)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#1473 converted the title and sports-hint matches in services/search/ranking.py
to word boundaries but left two raw substring tests:

  - snippet_score: 'term in snippet.lower()' — query term 'port' hits
    'transport'/'support', inflating a result's relevance.
  - news_quality_adjustment: 't in text or t in netloc' for the subject term —
    query 'us' substring-matches 'business'/'music', so an off-topic page
    wrongly escapes the off-topic penalty on a country/subject news query.

Add a _has_word helper (the same \b...\b pattern title_score already used) and
route all three word checks (title, snippet, subject) through it, so the file
stays consistent and a future partial fix can't reintroduce the same bug class.
Pure ranking refinement: scores change only for spurious substring matches; no
API or schema change.

(cherry picked from commit 22bd23f044f191bb30e43f6b68386552817f4cc3)

Subject: [PATCH 008/187] Strip tz in _parse_dt dateutil fallback
 (naive-datetime contract) (#2557)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_parse_dt documents that it returns naive datetimes (CalendarEvent.dtstart is
naive) and every return path strips tz — except the last-resort dateutil
fallback, which returned dateutil's value verbatim. An offset-bearing non-ISO
input (e.g. RFC-2822 'Mon, 05 Jan 2026 14:00:00 +0900', which fromisoformat
rejects but dateutil parses) leaked a tz-aware datetime into the naive dtstart
column via create_event/update_event -> _parse_dt_pair. On read-back,
_expand_rrule compares ev.dtstart against naive window bounds and raised
'can't compare offset-naive and offset-aware datetimes' (500 / no events).

Normalize the fallback to UTC-naive, mirroring the fromisoformat branch. Naive
inputs are unchanged.

(cherry picked from commit b03b6b91df21c1a3ad3c447f23f35b8b19e6d1b1)

Subject: [PATCH 009/187] Research CLI: alias `--status complete` to the stored
 `done` value (#2515)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`odysseus-research list --status complete` returns an empty result on
any real corpus. The CLI accepts `complete` as a `--status` choice (the
user-facing label), but the writer in
`services/research/research_handler.py` stores `status="done"` when a
run finishes (and the legacy `src/research_handler.py` copy does the
same). The list filter at `scripts/odysseus-research` was a literal
string compare:

    if args.status and (data.get("status") or "") != args.status:
        continue

so `--status complete` filtered every finished record out, and the user
saw nothing — even though `odysseus-research list` (no filter) listed
them fine and `show RP_ID` worked on the same files. The other
documented choices — `running`, `cancelled`, `error` — are stored
verbatim by the writer, so the surface mismatch is just on `complete`.

Add a small `_STATUS_CLI_TO_STORED = {"complete": "done"}` map and run
`data.get("status")` through `_status_matches(...)` before comparing.
The other CLI choices fall through unchanged, so the filter still
matches them verbatim. A `None` or non-string `status` (corrupt JSON)
is coerced to `""` and never matches `complete`, so a half-written
record can't sneak past the filter.

`tests/test_research_cli_status_filter.py` covers all four documented
choices, the non-string / missing status case, and pins that the
verbatim choices are NOT rewritten — a blanket mapping that turned
every CLI choice into a stored variant would just re-introduce the
empty-result bug on the running/cancelled/error paths.

Part of #2122.

Subject: [PATCH 011/187] fix(start-macos): skip pip install when
 requirements.txt is unchanged (#2503)

Hash requirements.txt on each launch and skip pip install if the hash
matches the last recorded value. Cuts 10-20s from warm starts with no
change to what gets installed.

The hash file lives in venv/.requirements_hash (already gitignored).
Deleting venv/ or changing requirements.txt triggers a full reinstall.

 safe

Test-only fix continuing #2523. Sets an in-memory DATABASE_URL default before tests/conftest.py imports core.database, preserving explicit DATABASE_URL values and avoiding ./data artifacts in clean worktrees.

Subject: [PATCH 021/187] fix(cookbook): surface backend diagnosis when serve
 fails in background (#1636)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor(cookbook): move _diagnose_serve_output to module level in cookbook_helpers

Extracts the nested _diagnose_serve_output function from inside
setup_cookbook_routes() and moves it to module level in cookbook_helpers.py,
alongside the other helper functions it logically belongs with.

No behaviour change — the function is now importable directly for testing
and by other callers without going through the route factory closure.

* fix(cookbook): surface backend diagnosis when serve fails in background

The background poll (_pollBackgroundStatus) already received `diagnosis`
and `cmd` from /api/cookbook/tasks/status but discarded both. When a serve
job died while the Cookbook modal was closed, reopening it showed only a
red error badge with no context.

- Persist live.diagnosis into task._backendDiagnosis in localStorage so it
  survives modal close/reopen and page refresh
- Persist live.cmd into task.payload._cmd for agent-spawned tasks so the
  crash report includes the actual command
- After _renderRunningTab(), walk rendered cards and call _showDiagnosis()
  for any that have a stored _backendDiagnosis but no panel yet
- In _renderTaskCard(), use _backendDiagnosis as a fallback when the
  client-side _terminalServeDiagnosis() finds nothing

* test(cookbook): add coverage for _diagnose_serve_output error patterns

10 tests verifying the 16 serve-failure patterns:
- CUDA OOM, port-in-use, vLLM missing, gated model
- Traceback fallback fires without startup success marker
- Traceback suppressed when server actually started
- Clean/empty output returns None
- trust-remote-code and no-GGUF patterns

Subject: [PATCH 024/187] Add ask_user tool: agent-posed multiple-choice
 questions (#2111)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let the agent pause and ask the user a multiple-choice question when a
task is genuinely ambiguous and the answer changes what it does next —
choosing between approaches, confirming an assumption, picking a target —
instead of guessing.

Modeled on the existing `ui_control` marker pattern: the `ask_user` tool
returns an `ask_user` payload that the agent loop emits as an SSE event
and then ends the turn. The frontend renders the question with clickable
option buttons, a free-text "Other" input, and an x to dismiss; the user's
choice is sent as the next message and the agent resumes with it in
context.

- src/tool_execution.py: `ask_user` handler — pure UI marker, no I/O.
  Validates a non-empty question + 2..6 options, normalizes string/object
  options, returns the payload.
- src/agent_loop.py: emit the `ask_user` event and break the round loop so
  the turn ends and waits for the user's selection. Stream the question as
  assistant text so it persists/replays (prevents a re-ask loop).
- Registration: TOOL_TAGS, ALWAYS_AVAILABLE, BUILTIN_TOOL_DESCRIPTIONS,
  FUNCTION_TOOL_SCHEMAS, the system-prompt blurb. Not admin-gated (any
  user can be asked); the structured args serialize via the default
  json.dumps path.
- routes/chat_routes.py: relay the `ask_user` event to the client.
- static/js/chat.js + static/style.css: render the question card (options +
  free-text Other + dismiss x; removed once answered). Reuses CSS vars and
  the .modal-close button; emoji go through the monochrome-SVG pipeline.
  Bump chat.js cache pin.
- tests/test_ask_user_tool.py: payload, multi flag, string options, option
  cap, validation errors, serializer round-trip, registration.

Subject: [PATCH 028/187] fix(images): render agent-generated images in chat
 (#2809)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(images): render agent-generated images in chat

When a chat model calls generate_image mid-conversation (agentic flow), the image does
not display — it survives only as a URL the model echoes in prose. generate_image runs
as a text-only MCP server, so result['image_url'] is never populated and the existing
buildImageBubble render path never fires. Promote the image URL out of the tool's stdout
in tool_execution so the agent loop's existing forwarding renders it via buildImageBubble
— deterministically, no dependence on the model echoing the URL. Backend-only; reuses
dev's image bubble, forwarding, and the tool's existing parseable output.

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

* feat(images): fully-qualified, valid generated-image links

The chat model often mangled the generated-image URL it echoed in prose (relative path,
or copying the 'image_url:' label into the link href). Build a fully-qualified link by
prefixing the existing app_public_url setting (empty default keeps relative paths), and
present it as a clean 'Direct link:' the model can echo verbatim (the frontend auto-links
bare https URLs). One file; independent of how the image is rendered.

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

* test(images): cover _promote_image_fields; make exit-code guard self-contained

Adds the unit tests requested in review on #2809: absolute URL, relative URL,
no URL (result unchanged), and non-zero exit_code (not promoted). Moves the
dict/exit_code==0 guard from the call site into _promote_image_fields so the
function is self-contained and the failure case is unit-testable; call-site
behavior is unchanged.

+
+    Test-only. Several route tests need the *real* ``src.endpoint_resolver`` URL
+    helpers, but another test may have installed a fake — a stub module with no
+    on-disk ``__file__`` — into ``sys.modules`` and onto the ``src`` package

+    passed in, e.g. ``routes.chat_routes``) get cached against that fake on first
+    import, so they must be evicted too.
+
+    Conservative, mirroring ``clear_fake_database_modules`` and the per-file
+    guards it replaces:
+
+    * It acts only when ``src.endpoint_resolver`` is a fake/stub, detected by a
+      falsy ``__file__`` (missing, ``None``, or empty string) — exactly the
+      truthiness check the old inline guards used. A real resolver loaded from
+      disk carries a truthy ``__file__`` and is left untouched, as is the case
+      where nothing is cached. When the resolver is real, the dependent route
+      modules are left untouched too.
+    * When it does act, it drops ``routes.model_routes`` plus every name in
+      ``extra_modules``.
+    * It removes the ``src.endpoint_resolver`` parent-package attribute only when
+      that attribute is the same fake object being evicted.
+
+    Behavior delta vs. the old bare ``sys.modules.pop(...)`` guards: dependent
+    modules are dropped via :func:`clear_module`, which also clears the parent
+    ``routes`` package attribute (e.g. ``routes.model_routes``), not just the
+    ``sys.modules`` entry. This prevents a stale parent attribute from shadowing
+    the fresh import — the same parent-attr handling the rest of this helper

Subject: [PATCH 036/187] Fix Windows Cookbook background tasks, exit statuses,
 and empty SSH logs wrapper (#1389)

This commit consolidates all Windows Cookbook background fixes into a single comprehensive commit based on the latest main branch.

Key fixes included:
1. React looksSuccessful Mismatch: Append 'DOWNLOAD_OK' for pip install commands in routes/cookbook_routes.py.
2. Local Windows SSH Wrapper & Log Directory Mismatch: Bypassed ssh wrappers and dynamically selected odysseus-tmux logs for local tasks in static/js/cookbookRunning.js.
3. WSL Bash Filtration: Filtered out the WSL bash stub at C:\Windows\System32\bash.exe in core/platform_compat.py.
4. Drive-Colon Path Normalization: Replaced .as_posix() with git_bash_path() in routes/shell_routes.py and src/bg_jobs.py.
5. GGUF-Only Hardware Fitting: Restructured local Windows recommendations to rank GGUF only in services/hwfit/fit.py.
6. Safe Win32 Process Liveness Probe: Replaced os.kill(pid, 0) with a safe Win32 API probe using GetExitCodeProcess in core/platform_compat.py.
7. Prebuilt llama-cpp-python Wheels: Supply the CPU extra index during compilation failure fallback.
8. Enforce UTF-8 log encoding: Set PYTHONIOENCODING=utf-8 on Windows bootstrap runners.
9. Fix Linux Llama.cpp Build script syntax error in routes/cookbook_helpers.py.
10. Page Reload Status Check: Run sys.executable instead of 'python3' to bypass Microsoft Store execution stubs on local Windows hosts.
11. Llama.cpp serve build bypass: Bypassed cmake compilation checks on local Windows and verified python bindings directly.
12. Serve Command Path Validation: Masked safe GGUF path printf subshells '' inside the serve command validator.
13. CPU Mismatch Diagnostics: Intercepted AVX2-lacking '0xc000001d' (Illegal Instruction) crashes in static/js/cookbook-diagnosis.js and guided users to Ollama.
14. Windows Pytest stability: Fixed stub import leakage in test files.

+# Test Suite Notes
+
+## Purpose
+
+This file documents the shared test helpers and the review expectations that go
+with them. The suite is being refactored incrementally, so this is a working
+reference for that effort — not a claim that the suite is already fully
+organized. Read it before adding a new helper or before reviewing a PR that
+touches `tests/helpers/`.
+
+## Core principles
+
+- Keep PRs small and homogeneous: one kind of change per PR.
+- Prefer explicit local setup over hidden global fixtures.
+- Avoid expanding the root `conftest.py` unless absolutely necessary.
+- Do not mix file moves with logic changes in the same PR.
+- Do not weaken tests with `skip`/`xfail` just to make CI pass.
+- Validate the focused files you changed, plus any neighboring or
+  order-sensitive groups they interact with.
+
+## Helper conventions
+
+The helpers below live under `tests/helpers/`. They exist to remove repeated
+boilerplate that already appeared across multiple tests. Reach for one only when
+your test matches its intended use; do not stretch a helper to cover a new case.
+
+### `tests.helpers.cli_loader.load_script`
+
+Use when a test needs to import a script under `scripts/` without repeating
+`SourceFileLoader` / `importlib.util` boilerplate.
+
+- Intended for script/CLI tests that load a single file from `scripts/`.
+- Not for arbitrary package imports — use a normal `import` for those.
+- When migrating an existing test to it, keep the existing stubs and assertions
+  unchanged. Any `sys.modules` stubs the script needs at import time must still
+  be injected (e.g. via `monkeypatch`) before calling `load_script`.
+
+### `tests.helpers.import_state.clear_module`
+
+Use when a test must drop one cached module and its parent-package attribute
+before a fresh import.
+
+- Clears `sys.modules[name]`.
+- Clears the parent-package attribute when present.
+- Good replacement for local `sys.modules.pop(...)` + `delattr(parent, child)`
+  blocks.
+
+### `tests.helpers.import_state.preserve_import_state`
+
+Use when a test temporarily installs stubs into `sys.modules` and needs
+deterministic cleanup afterward.
+
+- Context manager: restores both `sys.modules` entries and parent-package
+  attributes on exit (normal or exception).
+- Useful around module-level stubs or temporary imports.
+- Prefer narrow, explicit module names over broad ones.
+
+### `tests.helpers.import_state.clear_fake_database_modules`
+
+Use only for the guarded fake/stub database cleanup pattern.
+
+- Preserves a real-looking `core.database` (one with a string `__file__`).
+- Removes a fake/stub `core.database` and the related `src.database` state.
+- Do not use as a general database reset fixture.
+
+### `tests.helpers.import_state.clear_fake_endpoint_resolver_modules`
+
+Use only for the guarded fake/stub `src.endpoint_resolver` cleanup pattern.
+
+- Preserves real resolver modules (those with a truthy `__file__`).
+- Evicts fake/stub resolver modules and the dependent route modules that were
+  cached against them.
+- Accepts explicit extra dependent module names to evict alongside the defaults.
+
+## What not to abstract yet
+
+Some remaining patterns should stay as-is for now rather than being forced into
+helpers:
+
+- Large mixed files such as security/review regression files.
+- Setup-oriented `sys.modules` stub installers.
+- One-off custom module patching.
+- DB/session/route setup, until it has been audited separately.
+
+## Validation expectations
+
+Run validation locally before opening or approving a PR. Practical checks:
+
+- `git diff --check` — catch whitespace and conflict-marker errors.
+- `python3 -m py_compile <changed files>` — confirm changed files compile.
+- Focused `pytest` on the changed test files.
+- `pytest` on neighboring or order-sensitive test groups that share import
+  state with the changed files.
+- `grep` for the old boilerplate when replacing it, to confirm no stragglers
+  remain.
+- A fresh audit worktree when changing the helpers themselves, so stale
+  `__pycache__` or import state cannot mask a regression.
+
+## Current roadmap
+
+1. Import-state cleanup — complete.
+2. Document helper conventions (this file).
+3. Audit fake DB / `SessionLocal` / route setup duplication.
+4. Add tiny helpers only when the repeated semantics are clear.
+5. Start low-risk file moves only after helper conventions are documented.
+6. Avoid moving high-risk security/route regression files first.

Subject: [PATCH 041/187] fix: prevent document link click from resetting
 active session (#2055)

* fix: prevent document link click from resetting active session

Clicking a #document-<uuid> link in chat caused the session to reset
because of two issues:

1. chatRenderer.js: clicking on the text inside an <a> yields a Text
   node target whose .closest() is undefined, so preventDefault never
   fires and the browser performs a default hash-navigation

2. sessions.js: the hashchange handler treated the entity hash
   (document-<uuid>) as a session lookup, found no match, and the
   subsequent loadSessions created a new default-model chat

Fix: walk past Text nodes before calling .closest(), and skip
entity-prefixed hashes in the hashchange handler.

Fixes #2035

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(documents): move isOpen=true after container check in openPanel

isOpen was set to true before the #chat-container existence check.
If the container was missing during a race, the function returned
early but isOpen stayed true, preventing the panel from ever
reopening on subsequent calls.

Move isOpen=true to after the container guard so a failed open
doesn't leave the flag stuck.

Subject: [PATCH 042/187] fix(caldav): pull Google Calendar events from the
 events collection, not the /user principal (#2531)

* fix(caldav): pull Google Calendar events from the events collection, not the /user principal

Google serves its CalDAV principal at .../caldav/v2/<id>/user but events live
under .../caldav/v2/<id>/events. The caldav library's principal->home-set
discovery does not reliably enumerate calendars from Google's /user endpoint,
so _sync_blocking fell into its 'treat the URL as a single calendar' fallback
and ran every calendar-query REPORT against the principal URL. /user holds no
VEVENTs, so the REPORT returned a clean but empty 200 for every date range:
auth succeeded, the calendar stayed empty (Apple Calendar works because iCloud
exposes standard discovery at the pasted URL).

Add _google_caldav_events_url() to map a recognised Google principal URL to its
events collection, and route both discovery-less fallbacks through
_open_url_as_calendar() so Google syncs hit /events while other servers' URLs
are used unchanged.

Fixes #2507

* fix(caldav): also map Google's legacy www.google.com/calendar/dav principal URL

Some Google accounts authenticate against the older CalDAV endpoint
(https://www.google.com/calendar/dav/<id>/user) rather than the newer
apidata.googleusercontent.com/caldav/v2 form (reported on #2507). Both have the
same principal-vs-events split, so map the legacy /user URL to its /events
collection as well. The legacy branch is gated on the /calendar/dav/ path so an
unrelated www.google.com URL ending in /user is left untouched.

Subject: [PATCH 047/187] fix: Settings now correctly displays CalDAV
 integrations when more than one isconfigured (#2901)

* fix(calendar): expose source in calendar list and add per-calendar delete

- GET /api/calendar/calendars now includes source field so the frontend
  can distinguish CalDAV collections from local calendars
- Add DELETE /api/calendar/calendars/{cal_id} to remove a specific
  calendar and its events by owner-scoped ID

* fix(settings): show all CalDAV calendars in integrations list

Previously one card was shown for the CalDAV server connection regardless
of how many calendar collections had been synced. The Calendars page showed
them all; Settings did not.

- Fetch /api/calendar/calendars alongside existing requests and render
  one card per source=caldav collection, falling back to the single
  server-level card if nothing has synced yet
- Delete now targets the specific calendar by ID rather than clearing
  the whole server config
- Confirm dialog shows the calendar name so the user can verify before
  removing

Subject: [PATCH 049/187] feat: Add plan mode to the chat agent (#638)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat: Add plan mode to the chat agent

Adds a plan mode: the agent investigates read-only, proposes a checklist, and
waits for approval before changing anything. On approval it runs with full
tools and checks items off as it goes. Enforcement reuses the existing
disabled_tools gate.

Includes a slash command: `/plan [on|off]` (and `/toggle plan`) to flip the
plan toggle from the chat input.

- src/tool_security.py, src/mcp_manager.py: read-only allowlist (tools + MCP).
- src/agent_loop.py, routes/chat_routes.py: union the disabled set, prepend the

* Plan mode: persistent re-referenceable plan + agent write-back

Three improvements so a long plan survives a weak model and stays in reach:

1. Re-reference the plan (out-of-context fix). On the execution turn the frontend
   sends the approved checklist back (`approved_plan`); the backend pins it as a
   top-of-context `## ACTIVE PLAN` system note (kept by the context trimmer), so
   the agent can always re-read the plan instead of losing the thread on a long
   run. New `build_active_plan_note()` (unit-tested).

2. Re-open / dock the plan anytime. The plan checklist is stored per-session
   (localStorage). When a plan exists, the plan-mode button opens a small menu
   ("Show plan" / "Plan mode: On/Off") that re-opens the side-dockable plan
   window — so it can stay docked while the agent works. The window live-refreshes
   as the plan changes.

3. Agent write-back: new `update_plan` tool. The agent calls it to tick steps
   `- [x]` after finishing them, or to revise steps when the user asks. Marker
   tool (no I/O) → `plan_update` SSE event → the stored plan + docked window
   update live. The ACTIVE PLAN note instructs the agent to use it.

Backend: src/agent_loop.py (param + pin + note builder + emit + prompt blurb),
src/tool_execution.py (update_plan handler), routes/chat_routes.py (parse
`approved_plan`, relay `plan_update`), registration in tool_schemas / agent_tools
/ tool_index (always-available, not admin-gated).
Frontend: static/js/chat.js (plan store, send `approved_plan`, handle
`plan_update`, capture restated checklists), static/app.js (plan-button menu),
static/js/planWindow.js (`isPlanWindowOpen`), static/js/storage.js (PLAN key).
Tests: tests/test_plan_mode.py (plan-note), tests/test_update_plan_tool.py.

* Plan mode: drop bash/python, rely on read-only discovery tools

Shell can mutate (write files, hit the network) and can't be constrained to
read-only at the tool layer, so plan mode no longer relies on a prompt to keep
it well-behaved — bash/python are removed from the read-only allowlist and added
to the fail-closed block set. Discovery is covered by the dedicated read-only
tools (read_file, grep, glob, ls) instead.

Rewrites the plan-mode directive to state shell is disabled and lists the
available read-only tools positively. Addresses review feedback on #638.

* Comment: note _MCP_READONLY_VERBS are prefixes not whole words

Clarifies that entries like "summar" are intentional stems matched via
startswith (covers summarise/summarize/summary), not typos. Addresses review
feedback on #638.

* Plan mode: clarify why gating inverts the allowlist into a denylist

Rename _PLAN_MODE_FALLBACK_BLOCK -> _PLAN_MODE_KNOWN_MUTATORS and rewrite the
comments. The tool gate is a denylist (disabled_tools); plan mode's policy is an
allowlist, so it returns the inverse (all known tool names minus the allowlist).
The static mutator set is a backstop for the schema-derived name list, which
misses XML-only tools and can fail to import. Addresses review feedback on #638.

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

* Plan mode: stop hardcoding the read-only tool list in the directive

The model is already shown its available (read-only) tools by _assemble_prompt,
which removes every disabled tool. Enumerating them again in the directive only
duplicated that list and would drift as tools change. Point at the tools listed
below instead. Addresses review feedback on #638.

Subject: [PATCH 050/187] Improve edge-docked window behavior (#2779)

* Make edge-docked windows resizable

Add draggable resize seams for left and right docked windows.

Keep the main chat area from getting too narrow and remember each window's dock width.

* Show emoji shortcodes as icons by default

Keep text-only emoji mode opt-in so model output like :blush: goes through the normal emoji renderer.

* Fix dock resize seams and left dock layout

Hide the resize seam when another floating modal is open, and keep the left-docked window from covering the chat area.

* Keep narrow modal tabs usable

* Fix split layout with both edge docks

* Fix left snap after right dock

* Enable left edge snap for all windows

* Tighten dock resize handle observers

* Use edge docking for settings window

Subject: [PATCH 051/187] feat(skills): import SKILL.md bundles from public
 GitHub URLs (#2576)

* feat(skills): import SKILL.md bundles from public GitHub URLs

Supports GitHub tree/blob/raw links and skills.sh pages that resolve to GitHub.
Installs SKILL.md plus sibling text assets under data/skills/imported/.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(skills): admin-gate URL import and validate redirect hosts

- require_admin on POST /api/skills/import-from-url (matches other skill admin routes)
- reject cross-host redirects after httpx follow_redirects
- test for redirect host validation

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(skills): match Brain Add panel import/submit button styles

- Skill URL Import: theme-io-btn + download icon (same as memory Import)
- Add Skill submit: confirm-btn confirm-btn-primary

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(skills): allow api.github.com during directory import

Real imports hit the GitHub contents API after redirects; whitelist
api.github.com and add regression tests. Shrink Import button with flex:none.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(skills): align skill Import button with URL input row

Match memory-add-input height (28px) in memory-add-row and center the
download icon with flexbox instead of vertical-align hacks.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(skills): cancel modal-body margin on skill Import button

The skill Import button sits in .memory-add-row beside an input; the
global .modal-body button { margin-top: 6px } rule only affected buttons,
pushing Import down and misaligning the download icon. Reset margin-top
and match Memory Import SVG markup at 28px row height.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(skills): surface GitHub API errors on URL import

Pass through GitHub response messages (especially 403 rate limits) as
SkillImportError instead of a generic download failure.

Subject: [PATCH 054/187] feat(calendar): support multiple CalDAV accounts
 (#2942)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(calendar): support multiple CalDAV accounts

Replaces the single CalDAV credential slot with a named account list so
users can sync both a personal and work calendar simultaneously.

- Add `account_id` column to `CalendarCal` + startup migration
- `_load_caldav_accounts()` in caldav_sync.py reads `caldav_accounts`
  list from prefs, auto-migrating the legacy single `caldav` key on
  first use (no user action required)
- `sync_caldav()` iterates all accounts and aggregates counts/errors
- `writeback_event()` resolves credentials via `CalendarCal.account_id`,
  falling back to the first account for legacy rows
- New REST endpoints: GET/POST/PUT/DELETE `/api/calendar/config/accounts`
- Legacy GET/POST `/api/calendar/config` preserved for backward compat
- Settings UI: one card per account with Label, URL, Username, Password
  fields; Test button works for both unsaved (inline creds) and saved
  (by account_id) accounts; delete removes only that account
- Update test_caldav_url_hardening.py mock to include `_save_for_user`
  and updated `_sync_blocking` signature

* fix(calendar): restore #2765 PK scoping and #2819 writeback URL validation

Two regressions introduced by the multi-account refactor:

1. PK collision (#2765): _stable_cal_id was back to hashing only the URL,
   so two users — or one user with two accounts on the same server — would
   collide on the primary key. Restore owner+account_id in the hash key
   (format: "{owner}\n{account_id}\n{url}") and thread both values through
   _sync_blocking → _writeback_blocking → push_event → find_remote_calendar
   so the hash round-trips correctly on write-back.

2. URL validation dropped (#2819): _load_caldav_accounts imported
   _save_for_user at function scope, causing an ImportError on test mocks
   that only provide _load_for_user, which prevented writeback_event from
   reaching the validate_caldav_url call. Move the import inside the
   migration branch and wrap in try/except (best-effort save; next call
   re-migrates from the still-present legacy key).

Update fake_writeback_blocking in test_caldav_writeback.py to accept the
new owner/account_id optional params.

Subject: [PATCH 055/187] fix: respect user round count in deep research
 (#2896)

The STOP_PROMPT did not include the target round count, so the LLM
could decide to stop after 2-3 rounds even when the user requested 8.
Additionally, min_rounds was capped at 3 regardless of max_rounds.

- Add max_rounds to STOP_PROMPT so the LLM knows the target
- Change min_rounds from min(3, max_rounds) to max(2, max_rounds - 2)

Fixes #2863

Subject: [PATCH 060/187] fix: Add WSL paths to hardware detection fallback
 (#2933)

This change extends both the `PATH` variable and the list of absolute paths used to locate the `nvidia-smi` package to include `/usr/lib/wsl/lib`.
This path is a candidate for the default location of nvidia-smi for WSL machines (tested on WSL Ubuntu 22.04.5).

Subject: [PATCH 062/187] feat(reminders): add generic webhook as a fourth
 reminder channel (#2952)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces any Discord-specific reminder channel with a generic outbound
webhook channel. Users pick any saved Integration as the target and
supply a JSON payload template with {{title}} and {{message}}
placeholders — values are JSON-escaped before substitution. Works with
Discord, Slack, Teams, ntfy (JSON mode), or any service that accepts a
POST with a JSON body.

- `src/settings.py` — reminder_webhook_integration_id +
  reminder_webhook_payload_template defaults
- `routes/note_routes.py` — webhook delivery block; Integration lookup,
  template rendering, auth wiring; built-in preset defaults so
  discord_webhook works out of the box without a configured template;
  settings_override kwarg avoids test-button race condition
- `routes/auth_routes.py` — discord_webhook preset test handler
- `src/integrations.py` — discord_webhook preset with description +
  example templates; hides auth/key fields in the Integration form
- `src/builtin_actions.py` — webhook_sent delivery check
- `src/tool_implementations.py` — webhook aliases + enum updated
- `static/index.html` — Webhook channel option; Integration picker +
  payload template textarea
- `static/js/settings.js` — Integration list, populateWebhookIntegrations,
  syncChannelRows, hints, load/save, auto-fill preset templates,
  test-button override payload, hide auth/key for URL-auth presets

Subject: [PATCH 065/187] fix: raise imaplib line limit for large mailboxes
 (#2895)

Python's imaplib._MAXLINE defaults to 1 MB. Mailboxes with tens of
thousands of messages exceed this on UID SEARCH ALL, crashing with
'got more than 1000000 bytes'.

Set _MAXLINE to 50 MB after opening the connection so large mailboxes
work without error.

Fixes #2883

Subject: [PATCH 066/187] Phase 1: consolidate tool output constants into
 src/constants.py (#2989)

MAX_OUTPUT_CHARS, MAX_READ_CHARS, and MAX_DIFF_LINES are now
defined once in src/constants.py and imported by the three files
that previously duplicated them (tool_execution.py,
tool_implementations.py, agent_tools.py). agent_tools.py re-exports
them for backward compatibility.

Subject: [PATCH 070/187] fix(sessions): retry resumeStream in poll loop when
 chatModule loads late
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sessions.js executes before chat.js in ES module order, so
window.chatModule is not yet set when _checkServerStream runs on page
load. The resumeStream guard evaluates false and the spinner fallback
kicks in; that fallback only polls stream_status and never retries the
live-resume path, leaving the user with a dead spinner for the entire
duration of the detached agent run.

Fix: add a one-shot retry in the polling loop. On the first tick where
window.chatModule.resumeStream is available, attempt to attach. If it
succeeds, clear the interval and remove the spinner — live SSE streaming
takes over. If the run has already finished (404), the loop continues to
poll status and calls selectSession on completion.

Fixes #3048

Subject: [PATCH 071/187] fix(deep-research): wrap fetched webpage content in
 untrusted-context sandbox

The goal-based extractor passed raw fetched webpage content straight
into the LLM prompt via string substitution, bypassing the
prompt-injection hardening layer in src/prompt_security.py.

Split EXTRACTOR_PROMPT into EXTRACTOR_SYSTEM (task instructions +
goal, trusted) and a second message built with untrusted_context_message()
(raw page content, sandboxed with <<<UNTRUSTED_SOURCE_DATA>>> guards).
This aligns the extractor with every other external-content injection
site in the codebase (agent_loop, chat_processor, chat_routes).

Fixes #3044

Render streamed markdown incrementally (freeze finalized blocks,
re-render only the growing tail) instead of re-rendering the whole

+// Pure logic for incremental ("block-at-a-time") streaming markdown rendering.
+//
+// While an assistant message streams in, re-rendering the whole accumulated
+// markdown on every token is wasteful (O(N^2)) and recreates DOM nodes, which
+// makes code-block hover buttons flicker. The fix is to FREEZE the leading part
+// of the message that can no longer change, and only re-render the growing tail.
+//
+// This module answers the one hard question that makes freezing safe:
+//
+//     Given the full markdown received so far, how many leading characters can
+//     be finalized without changing the rendered output?
+//
+// The contract callers rely on (`render` is the canonical markdown renderer):
+//
+//     const n = splitFinalized(text, render);
+//     render(text.slice(0, n)) + render(text.slice(n))  ===  render(text)
+//
+// The module is intentionally DOM-free and renderer-agnostic so it can be unit
+// tested in isolation and reused for any markdown renderer with no long-range
+// cross-block dependencies (no reference-style links / footnotes).
+//
+// Known limitations (both bounded by the same mitigation):
+//   - cutIsRenderSafe proves only PRESENT-tense equivalence. If the renderer pairs
+//     an inline delimiter across a blank line (e.g. markdown.js will turn
+//     `*a\n\nb*` into emphasis spanning two paragraphs), a block frozen before the
+//     closing delimiter arrives can disagree with the final full render.
+//   - afterClosedFence boundaries are trusted without the equivalence check, so a
+//     fence the real renderer parses differently (e.g. a stray 4-backtick line) can
+//     be mis-detected as a close.
+//   Both only occur for input the renderer itself handles oddly, and both are
+//   transient: chat.js re-renders the finished message from source, so the settled
+//   output is always canonical.

Subject: [PATCH 076/187] ci: skip pytest smoke on documentation-only changes
 (#2768)

* ci: skip pytest smoke on documentation-only changes

Adding paths-ignore for **.md and docs/** so that PRs that touch only
markdown files do not trigger the full pytest suite. Runner minutes are
spent only when Python or config files change.

Closes #2646.

* ci: detect docs-only changes inside the job instead of paths-ignore

Previously paths-ignore on the pull_request trigger caused the entire
workflow to be skipped, which can leave required checks pending and block
merging. Instead, keep the workflow always-triggered and detect docs-only
changes inside python-tests with a git diff step; if every changed file
is a .md or docs/ path, the step reports success without running pytest.

The syntax jobs (python-syntax, node-syntax) are cheap enough to always run.

Subject: [PATCH 078/187] fix(security): close DNS-rebinding hole on
 diffusion_server (wildcard CORS + missing Host check) (#347)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

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

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

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

Subject: [PATCH 080/187] fix(webhooks): redact IPv6 addresses in sanitized
 error messages (#3038)

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

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

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

Adds tests/test_webhook_sanitize_error_ipv6.py.

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

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

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

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

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

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

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

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

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

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

Subject: [PATCH 081/187] fix(security): add HSTS and Permissions-Policy to
 SecurityHeadersMiddleware (#3081)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

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

Subject: [PATCH 082/187] fix(caldav): disable redirects on the sync/write-back
 DAVClient (SSRF) (#2663)

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

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

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

Subject: [PATCH 083/187] fix(email): guarantee IMAP conn.logout() on all
 exception paths (#1530)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

Subject: [PATCH 096/187] fix(cookbook): don't infer server OS from the
 browser's user-agent (#3223)

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

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

Fixes #3221

Subject: [PATCH 101/187] Fix: CORS preflight 401'd by AuthMiddleware before
 CORSMiddleware (#3262)

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

Let a genuine preflight through at the top of AuthMiddleware.dispatch via a pure,
unit-tested predicate (core.middleware.is_cors_preflight). Precise -- only

Subject: [PATCH 102/187] feat(tasks): assign folder='Tasks' at creation +
 backfill migration (#2834)

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

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

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

* feat: add backfill script for task session folders

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

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

* refactor: replace standalone backfill script with automatic migration

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

Subject: [PATCH 103/187] fix: fall back to /models probe when base URL returns
 404 (#3205)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

Fixes #3181

Subject: [PATCH 104/187] fix(agent): don't abort legitimate tool batches as
 runaway loops (#3183)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

Subject: [PATCH 105/187] fix: hide Select buttons in Memory/Skills tabs when
 list is empty (#2906)

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

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

* fix: dim disabled Select button and remove focus outline

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

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

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

This reverts commit 5b092ee6cd11d2a2bb79f74a9aa2a81b6b3aaa72.

Subject: [PATCH 106/187] fix(memory): record dislikes as dislikes, not
 preferences (#2435)

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

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

Subject: [PATCH 107/187] fix(context_compactor): return original messages when
 compaction summary fails (#2174)

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

Fixes #2160

 (#26)

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

Subject: [PATCH 109/187] fix: TOCTOU race in personal file delete + IndexError
 on whitespace cmd (#2228)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

Subject: [PATCH 110/187] fix(research): avoid double split() call and
 potential IndexError (#2229)

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

Subject: [PATCH 112/187] fix(skills): tolerate a stray brace before the JSON
 in skill extraction (#2200)

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

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

Adds tests/test_skill_extractor_json.py.

Subject: [PATCH 113/187] fix(email): decode headers without injected spaces
 (#2433)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Subject: [PATCH 116/187] fix: port main-only fixes to dev (#2761 sharpen auth,
 #2762 doc version 404) (#3303)

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

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

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

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

Subject: [PATCH 122/187] fix(hwfit): detect NVIDIA GPU on WSL and other
 minimal-PATH environments (#3306)

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

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

Subject: [PATCH 123/187] fix(cookbook): don't 500 the packages panel when an
 optional package crashes on import (#2618)

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

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

Subject: [PATCH 124/187] fix: show backend error detail in context-popup
 compact button (#2721)

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

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

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

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

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

Subject: [PATCH 127/187] fix: make agent loopback base port env-configurable
 (#2752) (#2753)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

Caught by #2752.

Subject: [PATCH 128/187] fix(notes): handle time-first due_date phrases in
 parse_due_for_user (#3319)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

Fixes #3302

Subject: [PATCH 130/187] Add hover tooltips for clipped model names (#1982)
 (#1985)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

Subject: [PATCH 131/187] fix: search analytics FileHandler crashes on startup
 writing to read-only image layer (#2366)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

Subject: [PATCH 133/187] fix(sessions): scope enrichment queries by owner, add
 LIMIT to auto_sort (#3350)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

Subject: [PATCH 135/187] fix(documents): discard pending AI diff before
 switching active doc (#2484)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Fixes #2467

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

Subject: [PATCH 137/187] refactor(tests): replace local function copies in
 test_endpoint_resolver with real imports (#3359)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Closes #3351

* refactor: import _ollama_api_root from llm_core instead of duplicating it

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

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

Subject: [PATCH 138/187] fix(security): harden untrusted_context_message
 against delimiter spoofing (#3086)

* fix(security): harden untrusted_context_message against delimiter spoofing

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

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

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

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

Resolves #3056

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

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

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

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

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

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

Subject: [PATCH 139/187] fix: route all agent loopback calls through
 internal_api_base() helper (#3322)

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

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

Part of #2752.

Subject: [PATCH 140/187] fix(documents): restore PDF library metadata and
 preview (#2483)

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

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

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

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

Fixes #2468

Subject: [PATCH 141/187] docs(contributing): require constants/helpers over
 hardcoded paths and URLs (#3335)

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

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

Part of #3331.

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

Subject: [PATCH 142/187] fix(search): write cache under DATA_DIR, guard mkdir
 against read-only path (#3334)

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

Part of #3331.

Subject: [PATCH 145/187] ci(pr-checks): conventional-commit title check,
 unmergeable-PR flagging, pin actions by SHA (#3336)

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

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

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

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

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

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

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

Subject: [PATCH 146/187] fix(ci): restore pull-requests:write for PR
 label/comment writes (#3367)

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

Subject: [PATCH 147/187] fix: expose supports_tools toggle for local endpoints
 in UI (#3195)

* fix: expose supports_tools toggle for local endpoints in UI

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

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

Fixes #3141

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

* Add Tools toggle screenshot for PR #3195

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

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

* Update Tools toggle screenshot (now dropdown select)

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

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

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

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

* chore: remove committed screenshots from tree

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

Subject: [PATCH 148/187] fix(skill-extractor): walk all brace candidates so
 stray braces in prose do not swallow valid JSON (#2205)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

Closes #2199

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

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

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

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

From 505d8bae5a99fcb77ece4e9655c376344a1eef01 Mon Sep 17 00:00:00 2001

Subject: [PATCH 150/187] fix(cookbook): locate cookbook_state.json via
 DATA_DIR, not hardcoded /app/data (#3332)

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

Part of #3331.

+# Odysseus Testing Standard & Taxonomy
+
+## Purpose
+
+This document defines *how we write and refactor tests* in Odysseus. It is the
+standard that the incremental test-suite refactor (issue #2523) works toward,
+and it applies to both human contributors and coding agents.
+
+It is intentionally split from [`tests/README.md`](./README.md):
+
+- **`README.md`** - the concrete, current helper reference: what each helper in
+  `tests/helpers/` does and how to call it.
+- **`TESTING_STANDARD.md`** (this file) - the rules and taxonomy: what a good
+  test looks like, where it belongs, and the policy refactor PRs must follow.
+
+When the two ever disagree, this file states the *intent* and `README.md` states
+the *current mechanics*; fix whichever is stale.
+
+This document changes no test behavior. It is guidance only.
+
+## What the test suite is for
+
+The goal is not only to reorganize `tests/`. The goal is for the suite to be a
+reliable foundation for future development: deterministic, modular, informative,
+behavior-focused, and complete enough to replace manual QA wherever practical.
+
+Run tests with the project virtualenv interpreter (`.venv/bin/python -m pytest`).
+The system `python3` may be missing pinned dependencies (e.g. `nh3`), which
+shows up as import/collection errors that are environmental, not real failures.
+
+## What "done" means for a single test
+
+Every new or refactored test should be:
+
+- **Deterministic** - same result every run, no reliance on wall-clock, network,
+  RNG seeds, or collection order.
+- **Behavior-first** - asserts on observable behavior, not on the source text or
+  AST of the code under test (see [Behavioral-first policy](#behavioral-first-policy)).
+- **Explicit** - setup and expected result are visible in the test, not hidden in
+  broad fixtures.
+- **Isolated from global process state** - no leaked `sys.modules`, `os.environ`,
+  CWD, or package parent-attribute mutation (see [Determinism & isolation](#determinism--isolation-rules)).
+- **Order-independent** - passes regardless of which tests ran before it.
+- **Environment-independent** - does not assume a venv layout, a developer's home
+  directory, an existing `./data` dir, or optional packages that may be absent.
+- **Informative on failure** - the assertion message or structure makes the cause
+  obvious without a debugger.
+- **Small** - understandable quickly; one behavior per test where practical.
+- **Backed by shared helpers only when duplication is proven** - not abstracted
+  preemptively.
+
+## Test taxonomy
+
+Tests are classified by the categories below. Today the suite is flat under
+`tests/`; the **Target dir** column is the phased layout from #2523 that we move
+toward *after* helpers and determinism are stable. Until a category is moved,
+new tests in that category stay in flat `tests/` but should still follow this
+standard.
+
+| Category | What it covers | Examples today | Target dir |
+|---|---|---|---|
+| **Route / API integration** | Real ASGI request/response, auth gates, admin gates, owner isolation through the app | files using `TestClient` | `tests/routes/` |
+| **CLI / script** | `scripts/` entry points and dev tooling | `tests.helpers.cli_loader.load_script` users, `test_pr_blocker_audit.py` | `tests/cli/` |
+| **Frontend / JS** | Browser-coupled JS run via Node subprocess; streaming-render invariants | `*_js.py` wrappers, `tests/streaming/*.test.mjs` | `tests/js/` |
+| **Tool execution / parsing** | Tool-call parsing, malformed/nonstring args, tool policy | `test_unknown_tool_calls.py`, `test_tool_policy.py`, `*_nonstring.py` | `tests/unit/` or `tests/services/` |
+| **LLM / provider** | Provider response parsing, streaming, sanitize, reasoning fallback | `test_llm_core_*`, `test_anthropic_response_parse.py` | `tests/services/` |
+| **Session / history / DB** | Session lifecycle, history, schema, ownership at the data layer | `test_session_*`, `test_sqlite_foreign_keys.py` | `tests/services/` or `tests/unit/` |
+| **Security / owner-scope / regression** | Owner isolation, auth, SSRF, path confinement, XSS, prompt injection, pinned regressions | `*_owner_scope.py`, `test_security_regressions.py`, `test_*ssrf*`, `test_*confinement*` | `tests/security/` |
+| **Cookbook / bootstrap** | Model serve lifecycle, dependency completion | `test_cookbook_*` | `tests/services/` |
+| **Scheduler / background** | Cron computation, background jobs, delivery | `test_compute_next_run_*`, `test_bg_*`, `test_task_scheduler_*` | `tests/services/` |
+| **Import / module isolation** | The isolation helpers themselves and their guarantees | `test_helpers_import_state.py` | `tests/unit/` |
+
+A test that genuinely spans categories (e.g. a route test that also pins a
+security invariant) is classified by its **primary** assertion target and may be
+split if it grows.
+
+## Determinism & isolation rules
+
+Do not mutate shared process state without a controlled helper and guaranteed
+cleanup. Specifically:
+
+- **`sys.modules` / parent-package attributes** - never assign at module scope.
+  Use `tests.helpers.import_state.preserve_import_state`, `clear_module`, or
+  `monkeypatch.setitem(sys.modules, ...)`. Restoring `sys.modules` alone is not
+  enough; the parent-package attribute must be restored too (the import-state
+  helpers handle both).
+- **`os.environ`** - use `monkeypatch.setenv` / `monkeypatch.delenv`, never raw
+  `os.environ[...] = ...` that outlives the test.
+- **Current working directory** - never `chdir` without restoring; never assert
+  against cwd-relative paths like `./data`. Use a temp workspace helper instead.
+- **Database** - the root `conftest.py` defaults `DATABASE_URL` to an in-memory
+  SQLite for collection safety. A test that needs a real file-backed DB must opt
+  in explicitly via `tests.helpers.sqlite_db.make_temp_sqlite` and bind its
+  `SessionLocal` onto the module under test. Do not rely on a persistent
+  on-disk DB existing.
+- **Optional dependencies** - do not require packages that may be absent in a
+  clean environment (e.g. `python-multipart`). Guard or stub them locally.
+- **Node-subprocess JS tests** - skip cleanly when `node` is absent
+  (`shutil.which("node")`), matching the existing wrappers. Treat a skip as a
+  coverage gap to be aware of, not a pass.
+- **Order independence** - a test must not depend on a sibling having imported,
+  cached, or stubbed something first. Order-sensitivity is a bug to fix, not a
+  constraint to encode.
+
+## Behavioral-first policy
+
+Prefer tests that exercise real behavior over tests that inspect source code.
+
+- **Avoid** `read_text()` + substring assertions, `ast.parse`, and
+  `inspect.getsource` checks when the behavior can be driven directly. Source-text
+  assertions break on benign refactors (renames, reformatting) and can pass even
+  when behavior regresses, because the asserted string still appears somewhere.
+- **Prefer** calling the function/route and asserting the outcome. Example: to
+  pin owner-scoping of `get_upcoming_events`, seed a temp DB with two owners and
+  assert one owner cannot see the other's events - rather than asserting the
+  source contains `q.filter(CalendarCal.owner == owner)`.
+- **Narrow exception** - a source-text/AST assertion is acceptable only when the
+  invariant cannot be practically exercised at runtime (e.g. pinning that a
+  required constant or guard literally exists in a module that is hard to drive).
+  When used, say *why* in the test docstring so it is a deliberate choice, not a
+  shortcut.
+- Do not convert source-text assertions to behavioral ones in the *same* PR that
+  moves files or changes unrelated setup.
+
+## Helper & factory extraction rules
+
+- Extract a shared helper only when the duplicated shape is **proven** - the same
+  setup repeated (ideally byte-identical) across multiple files.
+- Prefer **plain functions** in `tests/helpers/` over fixtures. Reach for a
+  fixture only when it is clearly scoped to one directory/category, and put it in
+  that directory's `conftest.py`, not the root.
+- Keep the **root `conftest.py` minimal** - `sys.path`, the DB-URL default, and
+  not-installed heavy-dependency stubs only. It is not a place for
+  feature-specific fixtures.
+- Each helper documents its **intended use and its limits** ("do not stretch this
+  to cover X"), as the existing helpers in `README.md` do.
+- Do not build a generic abstraction layer (factory framework, broad base
+  fixtures) before the repeated semantics are clear. Small and boring beats
+  clever and general.
+- Candidate factories, to add only after the duplication audit confirms the
+  shapes: fake users, fake sessions, fake requests, fake DB rows, fake LLM
+  responses, fake tool calls.
+
+## PR discipline for #2523 refactor slices
+
+- Keep each PR small, reviewable, and behavior-preserving - unless the PR's stated
+  purpose is to add new coverage.
+- **One kind of change per PR.** Do not mix:
+  - file moves with assertion changes;
+  - helper extraction with logic changes;
+  - import-state cleanup with DB-fixture changes.
+- Do not weaken assertions, add `skip`/`xfail`, or delete coverage just to make CI
+  green. A red test is a signal to investigate, not to silence.
+- Prefer 3-6 files per refactor batch, and only when they share the *same*
+  pattern.
+- Distinguish a stale test expectation from a real production-policy change before
+  "fixing" a failing test - never edit a test to match a regression.
+
+## Validation expectations
+
+Run locally before opening or approving a refactor PR:
+
+- `git diff --check` - whitespace and conflict-marker errors.
+- `python3 -m py_compile <changed .py files>` - changed files compile.
+- Focused `pytest` on the changed files (use `.venv/bin/python -m pytest`).
+- `pytest` on neighboring / order-sensitive groups that share import state with
+  the changed files.
+- When replacing boilerplate, `grep` for the old pattern to confirm no stragglers.
+- When changing a helper itself, validate in a fresh worktree so stale
+  `__pycache__` or import state cannot mask a regression.
+- For order-sensitivity, a randomized run (once `pytest-randomly` is available in
+  the dev environment) is the strongest check; record the seed on failures.
+
+## Target directory structure (phased)
+
+Move toward this layout *gradually*, only after helper conventions and
+determinism are stable. Low-risk categories move first; oversized catch-all files
+are split last.
+
+```
+tests/
+  conftest.py        # stays minimal
+  README.md          # helper reference
+  TESTING_STANDARD.md
+  helpers/           # plain helper functions (exists)
+  unit/              # pure helper/module tests
+  cli/               # scripts/ + CLI tests
+  js/                # node-subprocess + streaming tests
+  security/          # owner-scope, auth, SSRF, confinement, regressions
+  routes/            # TestClient integration (per-dir conftest for the client)
+  services/          # service-layer tests
+  integration/       # only if a cross-cutting flow needs it, later
+```
+
+Suggested move order: **js / cli first → security / routes / services → split
+oversized catch-all files last.** Each move is mechanical (no assertion changes
+in the same PR), with an identical pass set before and after.
+
+## Related: CI-hardening track (tracked separately)
+
+Making the suite an enforced gate is broader than #2523's organization scope and
+should be tracked as its own effort. The intended sequence:
+
+1. Add non-blocking randomized pytest reporting (`pytest-randomly`) so hidden
+   order-dependence becomes visible without changing any test.
+2. Fix surfaced order-dependence in small same-pattern batches.
+3. Add coverage reporting with no threshold gate.
+4. Only then make the pytest job a blocking CI gate.
+5. Consider `pytest-xdist` / parallel isolation after deterministic
+   single-process randomized runs are stable.

Subject: [PATCH 152/187] fix(search): catch HTTPStatusError so 403/404 URLs
 degrade gracefully instead of 500 (#2203)

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

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

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

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

Closes #2148

Subject: [PATCH 153/187] fix(compare): stream Compare panes directly to stop
 upstream promptly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

 Don't hardcode values that the project already exposes through a constant or a helper. Hardcoded literals drift out of sync, break on non-default deployments, and reintroduce bugs we've already fixed.
 
-- **Filesystem paths:** never build writable paths from `Path(__file__)...` into the source tree or hardcode `/app/...`. Use `DATA_DIR` (and the other path constants) from `core.constants`, e.g. `Path(DATA_DIR) / "logs" / "x.log"`. The source tree is read-only in Docker, and `/app/...` does not exist on native runs. Guard directory creation so an unwritable path degrades gracefully instead of crashing at import.
-- **Internal API / loopback URLs:** don't hardcode `http://localhost:7000`. Use `internal_api_base()` from `core.constants` (it honors `ODYSSEUS_INTERNAL_BASE` / `APP_PORT`).
+- **Filesystem paths:** never build writable paths from `Path(__file__)...` into the source tree, hardcode `/app/...`, or use a relative `"data/..."` string. Every persisted file and directory has a named constant in `src/constants.py` (for example `AUTH_FILE`, `USER_PREFS_FILE`, `SETTINGS_FILE`, `TTS_CACHE_DIR`, `CHROMA_DIR`). Import and use that named constant; do not re-derive the path locally with `os.path.join(DATA_DIR, "x.json")` or `DATA_DIR / "x.json"`. `DATA_DIR` is the single place that reads `ODYSSEUS_DATA_DIR`, so use it directly only for dynamic paths that have no fixed name (for example per-owner files). If a data file or directory has no constant yet, add one to `src/constants.py`. The source tree is read-only in Docker and `/app/...` does not exist on native runs; guard directory creation so an unwritable path degrades gracefully instead of crashing at import.
+- **Internal API / loopback URLs:** don't hardcode `http://localhost:7000`. Use `internal_api_base()` from `src.constants` (it honors `ODYSSEUS_INTERNAL_BASE` / `APP_PORT`).
 - **Ports, limits, model lists, and similar:** reuse the existing constant if one exists; if it doesn't and the value is used in more than one place, add a constant rather than copying the literal.
 
-If you need a value that has no constant or helper yet, add one in the appropriate module (usually `core/constants.py` or `src/constants.py`) and import it, rather than repeating a literal across files.
+If you need a value that has no constant or helper yet, add it to `src/constants.py` (the single source of truth for paths and config; `core/constants.py` only re-exports it for backward compatibility) and import it, rather than repeating a literal across files.
 
 **Commits:** use [Conventional Commits](https://www.conventionalcommits.org), `type(scope): summary` (e.g. `fix(search): ...`, `feat(notes): ...`, `docs(contributing): ...`). Common types: `fix`, `feat`, `refactor`, `docs`, `test`, `chore`, `ci`. Keep the subject short and imperative; put the "why" in the body when it isn't obvious.

Subject: [PATCH 155/187] feat: add ChatGPT Subscription provider (#2876)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat: Add ChatGPT Subscription support and related features

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

* refactor: share provider device-flow setup

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

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

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

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

* fix: harden chatgpt subscription provider

* chore: remove PR media from branch

* Fix chatgpt subscription recovery and token handling

Subject: [PATCH 156/187] fix: hide shell access and plan mode buttons in chat
 mode (#3417)

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

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

Fixes #3411

Subject: [PATCH 157/187] fix(issue-template): validate bug reports against
 dev, not main (#3420)

Cloners default to the dev branch (CONTRIBUTING: main is the curated
release, dev is where fixes land). The bug template required ticking
'latest code from main', so reporters confirm a stale branch and bugs
already fixed on dev get re-filed. Ask them to reproduce on latest dev.

Subject: [PATCH 158/187] ci: publish multi-arch Odysseus image to GHCR (dev +
 stable) (#3423)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* ci: build and publish multi-arch Odysseus image to GHCR

Push to main publishes :latest and :X.Y.Z; push to dev publishes :dev and
an immutable :X.Y.Z-dev.<sha>. Multi-arch (linux/amd64 + linux/arm64) via
per-arch native runners building by digest, merged into one manifest list.
Uses the in-repo GITHUB_TOKEN (packages: write), actions pinned by SHA.

* ci(docker): pin actions to latest major releases

checkout v6.0.3 (matches the PR-checks workflow), setup-buildx v4.1.0,
login v4.2.0, build-push v7.2.0, metadata v6.1.0, upload-artifact v7.0.1,
download-artifact v8.0.1 — all by commit SHA.

Subject: [PATCH 159/187] fix(ci): correct malformed expression in
 docker-publish Inspect step (#3425)

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

Subject: [PATCH 160/187] fix(endpoint): scope secondary endpoint lookups by
 owner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Scope secondary endpoint lookups by owner

* Reject unregistered image endpoint URLs for non-admins

* Adjust owner-scope tests for rebased routes

* Allow non-admins to compare endpoints they own

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

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

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

* Bind compare sessions to the resolved owner-scoped endpoint

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

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

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

Addresses the review on #1511.

* Validate both compare endpoints before creating any session

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

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

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

Addresses the follow-up review on #1511.

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

* Resolve compare credentials by endpoint id, not URL alone

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

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

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

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

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

Subject: [PATCH 161/187] feat(chat): recall last user message on empty
 composer ArrowUp (#1175)

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

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

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

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

- Add tests/test_composer_arrow_up_recall_js.py

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

Subject: [PATCH 165/187] fix(memory): only delete memories the model
 explicitly drops in tidy (#3455)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

Addresses review feedback on #3455.

Subject: [PATCH 166/187] fix(caldav): skip the prune when any object fails to
 parse (#3454)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Adds tests/test_caldav_prune_parse_failure.py for the three cases.

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

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

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

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

Subject: [PATCH 167/187] fix(presets): persist presets atomically to avoid
 corruption on crash (#2169)

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

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

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

Subject: [PATCH 168/187] fix(api-tokens): preserve scopes on a partial token
 update (#3407)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Subject: [PATCH 169/187] fix(memory): make auto-memory extraction reliable for
 reasoning models (#3190)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

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

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

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

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

Subject: [PATCH 170/187] fix(security): fail closed in /api/models auth gate
 on unexpected errors (#3489)

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

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

Subject: [PATCH 171/187] fix(sessions): copy message metadata when forking a
 session (#3409)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Subject: [PATCH 172/187] ci: harden existing workflows for the security gate
 (#3498)

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

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

Subject: [PATCH 173/187] fix(presets): scope expand-prompt model resolution to
 owner (#3477)

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

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

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

Subject: [PATCH 174/187] fix(email): close IMAP socket when connect/login
 fails (#3174) (#3363)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

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

Subject: [PATCH 175/187] fix(chat): keep balanced trailing ')' when extracting
 URLs (#3406)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

Subject: [PATCH 176/187] fix(agent): stop treating illustrative Markdown
 fences as tool calls for native function-calling models (#3356)

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

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

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

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

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

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

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

+"""Issue #3222 — native function-calling models (GPT/Claude/Grok/Qwen3/DeepSeek-V,
+etc.) must not have ordinary illustrative Markdown fences in their prose
+(```bash, ```python, ```json examples written for the user to read) executed
+as real tool calls just because the textual fallback parser matches them.
+
+`_resolve_tool_blocks` in src/agent_loop.py picks native `tool_calls` when the
+model emits them, and otherwise used to fall back unconditionally to
+`parse_tool_blocks(round_response)` (the fenced-block textual parser). For a
+native model that produced no real tool_calls — e.g. a "guide-only" turn where
+the model writes an example command for the user to copy — that fallback used
+to treat the example fence as an executable action, causing accidental command
+execution and multi-round loops.
+
+The fix: for native function-calling models (`_is_api_model=True`) that emitted
+no native tool_calls, skip the textual fenced-block fallback entirely — these
+models have a reliable structured channel and a bare fence in their prose is
+display text, not an attempted call. Non-native / textual-only models keep the
+fallback unchanged, since fenced blocks are their *only* tool channel.
+
+These tests drive the real `stream_agent_loop` (not just source-text regex
+assertions) end-to-end with a mocked LLM stream, and assert on whether
+`execute_tool_block` actually gets invoked.

Subject: [PATCH 177/187] fix(auth): per-user allowed-models checklist ignores
 cache, [None] doesn't block (#3355)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

Subject: [PATCH 180/187] test(models): add regression coverage for Z.AI coding
 endpoint probing (#2244)

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

Rebased onto dev per reviewer request.

Fixes #2230

Subject: [PATCH 182/187] refactor(tools): consolidate duplicated _truncate and
 get_mcp_manager into src/tool_utils (#3478)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

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

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

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

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

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

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

Subject: [PATCH 185/187] refactor(uploads): centralize upload byte-limits in
 upload_limits.py (#3364) (#3518)

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

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

Fixes #3364
