fix(harness): ship coherent vendor harness cluster

Rebuild PR C to ship the vendor/photocraft harness as a coherent unit
(vendor implementation + vendor tests) instead of a per-file ahead/behind
mix that produced broken imports and 6+ test failures.

- Flip 36 harness impl/route/test files back to vendor (the per-file
  line-set policy misclassified user-rewritten files as 'behind').
- Flip core/models.py + src/tool_approval_scopes.py to vendor: vendor's
  harness (authority.py, turn_contract.py, clean_agent_preview.py) depends
  on vendor's older approval-scope API; upstream added
  CHAT_SESSION_APPROVAL_SIGNATURE_FIELD that vendor's core/models.py lacks.
- Add src/shutdown.py (new vendor infra) required by routes/chat_routes.py.
- Keep src/agent_tools/__init__.py at upstream (editor_tools registration
  lives in PR B).

Upstream-only security divergence preserved in C_upstream_delta.patch and
flagged for integration-time reconciliation.

Until those are covered by their own boundaries, this gate is what stops an injected instruction from reaching them. Turning it off lets a successful injection reach `bash`, `host_shell`, `send_email` and `delete_email` without a separate confirmation.

+## Contamination map
+
+| Source | Mutation / binding | Previous cleanup | Escaping state / effect |
+| --- | --- | --- | --- |
+| Both tests in `tests/test_truncate_message_count_regression.py`, through `_make_manager` | Creates an unowned `mkstemp` DB; directly sets `os.environ["DATABASE_URL"]`; reloads `core.database` then `core.session_manager` | Only the assertion's ORM session is closed | Environment, engine, factory, declarative Base, ORM classes, manager globals, and registered engine listeners survive; database files are never deleted |
+| Collection of `tests/test_manage_tasks_owner_scope.py` | Creates a module-lifetime temporary DB and assigns `_TS` permanently to `core.database.SessionLocal` | Some individual rows deleted; ORM sessions closed | The collection-time factory assignment leaks to unrelated tests; truncation reload replaces it, so production handlers and `_seed` / `_get` use different databases |
+| `test_checkin_digest_owner_scope.py`, `test_gallery_owner_filter_single_user.py`, `test_document_session_owner_scope.py` | Create module-lifetime DB files / engines and retain local factories | Some rows deleted / route factory restored / ORM sessions closed | Owned files and engines lack teardown; retained imported ORM identities can disagree with reloaded module globals |
+| `tests/conftest.py` bootstrap | `DATABASE_URL` was set only if absent before importing `core.database` | No environment restoration | An inherited developer URL could be opened and initialized during collection |
+
+`importlib.reload` updates the existing module dictionary in place; it does
+not change the `sys.modules` module object's identity. Previously imported
+symbols nevertheless keep their old class/factory identities. In particular,
+`src.database` re-exports old objects, while reloaded `core.session_manager`
+rebinds its `DbSession`, `DbChatMessage`, `DbDocument`, `SessionLocal`, and
+`SessionManager`. Old functions still resolve globals through those changed
+module dictionaries. Each database reload also registers a new SQLite connect
+listener on SQLAlchemy's Engine class.
+
+The current failures are principally in `test_manage_tasks_owner_scope.py`:
+`_seed` writes through its retained `_TS`, but `do_manage_tasks` imports the
+now-replaced factory from `core.database` at call time. Ownerless / cross-owner
+mutations incorrectly observe "task not found"; successful mutation/list/create
+witnesses likewise read or write the wrong test database. Four invalid-date
+cases still pass, so the observed contamination count is 16 rather than all
+20 task-owner cases.
+
+`src.settings` has TTL caches, but those caches do not resolve DATABASE_URL.
+The contaminating helper neither patches nor reloads settings. The database
+URL is read directly from the environment at database import/reload time;
+settings cache invalidation is not the correction for this leak.
+
+## Baseline reproduction before editing
+
+All baseline commands explicitly selected in-memory bootstrap storage. Python
+with installed pytest/SQLAlchemy was
+`/tmp/pr40-final-validation-venv/bin/python` (pytest 9.1.1, SQLAlchemy 2.1.1).
+
+```sh

+# 2 failed (IndexError), 1 passed, 13 deselected, 1 warning in 1.61s
+```
+
+The same 30 database tests shuffled with `random.Random(42)` before editing
+reported **9 failed, 21 passed**, 9 warnings in 2.37s. Exact command:
+
+```sh

+```
+
+## Isolation correction and regression evidence
+
+- `tests/helpers/database.py` owns a fresh TemporaryDirectory, file-backed
+  SQLite engine with NullPool, real schema, and factory for each invocation.
+  Teardown disposes the engine and removes the directory including sidecars.
+- The truncation fixture temporarily patches only resource bindings in
+  `core.database`, `src.database`, and `core.session_manager`, with a matching
+  temporary environment URL. Patches are undone before resource disposal.
+  No module reload, module eviction, new ORM class, or listener registration.
+- Four owner modules now own a disposable database per test rather than at
+  collection. Only the task-owner module patches the canonical factory; that
+  patch is scoped to the test and restored during teardown. The other modules
+  retain their existing handler/route wiring and ownership assertions.
+- The existing pytest bootstrap always chooses in-memory storage before
+  production database imports and registers environment restoration with the
+  pytest configuration lifecycle. No new process-wide autouse cleanup fixture.
+- `tests/test_database_test_isolation.py` checks real persistent truncation,
+  exact class/factory restoration, file removal, clean subsequent database
+  state, and exception teardown. Child pytest runs execute the actual original
+  witness entry points in both directions and check process-visible bindings
+  after collection and after every test. An inherited developer-DB sentinel
+  remains byte-identical, with no database sidecars created, and the inherited
+  environment URL is restored after pytest exits.
+
+Mutation checks temporarily restored one original file at a time, ran
+`test_actual_tests_restore_process_state_and_ignore_inherited_database[True]`,
+and restored the corrected file in `finally`. Both mutations made the new
+regression fail (pytest exit 1): original truncation was caught as
+"test leaked database or module state", original task-owner collection as
+"collection changed database bindings". No mutation was retained.
+
+## Historical negative-web witnesses and production blocker
+
+Both parameter cases in
+`test_negative_web_wording_withholds_the_web_tools_unhandled` intended to prove
+that inferred negative-web wording can receive a memory-only answer without
+`web_search` or `web_fetch` being offered to the model:
+
+1. `Summarise what you already know. Do not search the web.`
+2. `No web search please, just tell me what you know about Python decorators.`
+
+Both previously indexed an empty fake-model call list and xfailed on unrelated
+`IndexError`. The fake also emitted provider-shaped `choices` JSON at a seam
+that now consumes normalized `{"delta": ...}` SSE.
+
+The repaired witnesses drive the unmodified public `stream_agent_loop`, mock
+only model output and existing infrastructure edges, capture the actual SSE,
+and require one model call, withheld web schemas, and delivered fake answer.
+The existing passing "don't search online" control and positive search
+control remain. The fake now emits normalized SSE.
+
+The two historical xfails remain **strict**, with
+`raises=_MemoryOnlyTurnBlocked`. That exception is emitted only when the real
+loop makes zero model calls and returns the exact known disabled-web response.
+IndexError, arbitrary assertions, or other exceptions no longer qualify.
+
+This is a genuine production defect outside the lane: negative-web detection
+is true for both phrasings, but `_classify_agent_request` returns `{'web'}` and
+`_web_search_unavailable_for_turn` returns true after the negative has disabled
+web tools. The loop short-circuits the requested memory-only response with:
+
+> Web access is disabled for this turn. Enable web search and resend the request.
+
+The passing "Answer from memory only, don't search online." control has
+`{'memory', 'web'}` intent domains and does not short-circuit. A minimized
+reproduction using those three production functions requires neither a model
+nor a mock. Relevant production locations (intentionally untouched):
+`src/agent_loop.py` negative detector near line 864, classifier near 10371,
+negative-tool disabling near 20735, unavailable calculation near 22233, and
+short-circuit response near 25101.
+
+```sh
+/tmp/pr40-final-validation-venv/bin/python -m pytest -q -p no:cacheprovider --runxfail tests/test_runtime_behavior_regressions.py -k negative_web_wording_withholds_the_web_tools_unhandled
+# 2 failed with _MemoryOnlyTurnBlocked, 14 deselected, 1 warning in 0.75s
+```
+
+No production repair was attempted. Runtime intent/availability behavior,
+authority, completion/evidence, and Wave 4 effects files remain untouched.
+This blocker prevents a READY release-foundation verdict despite passing test
+isolation validation.
+
+## Final order validation
+
+The focused manifest has 50 cases: the five baseline database modules plus
+`test_database_test_isolation.py` and `test_runtime_behavior_regressions.py`.
+Normal collection order is alphabetical by the seven explicitly selected files.
+Reversed and seeded runs reorder **individual collected test cases**, including
+parameterized cases. Both contamination directions also vary file collection
+order. Every execution manifest is retained as JSON in the evidence directory.

+## Adjacent and complete validation
+
+The first complete run finished with **44 failed, 12509 passed, 62 skipped,
+2 xfailed**, 184 warnings and 6 passing subtests in 391.85s. Its failure
+inventory was 42 missing-Playwright-package failures and two generated
+configuration-reference freshness failures. The local worktree had not had
+`npm ci` run; the generator includes test-source line references, and the
+bootstrap edit moved the existing references by one line.
+
+`npm ci --ignore-scripts` installed the four already-locked packages; package
+and lock files were unchanged. Cached Chromium launched successfully
+(version 151.0.7922.34). A bootstrap comment now explains why isolation must
+precede collection and preserves the existing referenced line locations,
+without editing the generated website or the generator. This follow-up is
+commit `f67d0388fd805867a0920dbffd4da056b1361e38`
+(`fix(tests): preserve bootstrap reference locations`).
+
+```sh
+npm ci --ignore-scripts
+# exit 0; 4 packages installed, lockfile and package policy unchanged
+
+python scripts/generate_env_reference.py --check
+# exit 0; website/configuration-reference.md is up to date (112 variables)

+# 16 passed, 1 warning in 17.00s
+```
+
+The first full run and the 44-case focused rerun are retained separately from
+the final complete run. The 44-case rerun reported **1 failed, 43 passed**
+in 73.61s: the existing font/color browser witness observed its font-size
+icon still showing `13` after its text had changed to size 5 (expected `24`).
+An isolated reproduction of that unchanged test passed in 2.13s. This is an
+observed intermittent browser UI witness; no database failure was involved,
+and a production root cause has not been established. The test and editor
+implementation remain unchanged, with both observations retained rather
+than suppressing the failed run. No failure was hidden by skipping or deleting a test.

+The isolation commit is
+`e2b847c84d27ce785565757e81ca5293896eaab3`
+(`fix(tests): isolate database and module state`). The final bounded commit
+contains the repaired web witnesses and this validation report. Final commit,
+HEAD, TREE and clean status are supplied in the accompanying final report to
+avoid placing a commit's own hash inside its committed contents.
+
+Full logs, commands, and per-run manifests from this session are in
+`/tmp/odysseus-wave6-isolation-evidence/`.
+
+The follow-up normal focused run after preserving bootstrap reference
+locations is recorded in `after-bootstrap-followup.log`. It reported **48 passed, 2 xfailed**, 11 warnings in 9.55s. Its exact command is:
+
+```sh
+/tmp/pr40-final-validation-venv/bin/python /tmp/odysseus-wave6-isolation-evidence/run_order.py normal after-bootstrap-followup tests/test_checkin_digest_owner_scope.py tests/test_database_test_isolation.py tests/test_document_session_owner_scope.py tests/test_gallery_owner_filter_single_user.py tests/test_manage_tasks_owner_scope.py tests/test_runtime_behavior_regressions.py tests/test_truncate_message_count_regression.py
+```
+
+The additional browser observation came from the 44-case manifest retained in
+`full-failures-manifest.json`; every exact node ID in that diagnostic command is
+retained in `full-failures-rerun-command.json`. The isolated diagnostic command:
+
+```sh
+/tmp/pr40-final-validation-venv/bin/python -m pytest -q -p no:cacheprovider tests/test_document_rich_font_color_controls.py::test_numeric_font_size_and_custom_colors_work_on_desktop_and_mobile
+# 1 passed, 1 warning in 2.13s
+```
+
+## Independent review disposition
+
+A read-only review of isolation commit e2b847c8 raised two concerns, which
+were checked against the frozen source rather than accepted as proven leaks:
+
+- `core.models._SESSION_MANAGER_INSTANCE`: `SessionManager.__init__` only
+  initializes its owned cache and loads metadata; it does not call the global
+  setter. `SessionManager.add_message` explicitly persists through its own
+  manager instead of calling `Session.add_message` / the singleton. Neither
+  truncation witness nor the helper invokes a singleton setter or API route
+  setup. Thus the asserted singleton mutation is absent from this lane's real
+  seam. Resetting that unrelated singleton would add cleanup without a proven
+  owned mutation and could hide a genuine leak elsewhere.
+- Eager real-database import versus `clear_fake_database_modules`: the exact
+  pre-import block already exists on frozen b1666951. The clearing helper
+  intentionally leaves real modules with a string `__file__` intact and evicts
+  replacement fake modules lacking it. The correction neither adds that
+  pre-import nor changes fake-module identification. Its "real module" early
+  return is intended behavior, not a newly introduced cleanup conflict.
+
+Neither concern supplied a failing reproducer. Both were resolved by the
+existing source paths and the actual collection/teardown identity regression;
+no speculative global cleanup was introduced.
+
+The minimized production reproduction command was:
+
+```sh
+DATABASE_URL=sqlite:///:memory: /tmp/pr40-final-validation-venv/bin/python - <<'PYTHON'
+from src.agent_loop import _explicitly_avoids_web_lookup, _classify_agent_request, _web_search_unavailable_for_turn
+from src.tool_policy import WEB_TOOL_NAMES
+for text in (
+    "Answer from memory only, don't search online.",
+    'Summarise what you already know. Do not search the web.',
+    'No web search please, just tell me what you know about Python decorators.',
+):
+    intent = _classify_agent_request([{'role': 'user', 'content': text}], text)
+    domains = set(intent['domains'])
+    print(repr(text))
+    print('negative_web:', _explicitly_avoids_web_lookup(text))
+    print('intent_domains:', sorted(domains))
+    print('web_disabled_short_circuit:', _web_search_unavailable_for_turn(domains, set(WEB_TOOL_NAMES), text, None, None))
+PYTHON
+```
+
+Results: negative-web detection true for all three; intent domains respectively
+`['memory', 'web']`, `['web']`, `['web']`; short-circuit false, true, true.
+
+## Final validation result and verdict
+
+The final complete run in `full-pytest-final.log` exited 0:
+**12556 passed, 59 skipped, 2 xfailed**, 184 warnings and 6 passing subtests in
+468.49s. All 12617 collected cases are accounted for. The existing optional,
+platform-specific and opt-in skips remain; no skip marker was added. Installing
+the already-locked Node dependencies enabled three previously skipped cases,
+so the skip count decreased from 62 in the first run to 59. No tests were
+deleted and no unrelated xfail was introduced.
+
+The font/color browser witness passed in the final complete run. Its failed
+44-case diagnostic and passing isolated result remain documented as an
+intermittent observation; no production root cause was established or fixed.
+
+Database/environment/module isolation validation is green. Both historical
+negative-web cases remain narrowly expected failures for a reproduced genuine
+runtime defect outside the test-isolation boundary. These are integration
+blockers; production intent/short-circuit behavior must be corrected in an
+appropriate lane before removing their strict markers.
