Thinking Path

Vehicle 2f merges eight already-reviewed, green PR heads (unchanged) onto current main, resolving the conflicts between them in explicit merge commits, plus one required fix commit for references mcp/'s rename stranded. #16732 was included because, at the moment it was reached, its review approval was recorded against its then-current headRefOid, matching the rule for inclusion.

What Changed

Members merged, each at its pinned/approved SHA, in this order:

Conflict resolutions and fix commits

File Resolution
autobot-frontend/src/i18n/locales/fr.json (#16471) Same-key value conflict on collaboration.panel.title; took #16471's "Espace collaboratif" — the other side's value was just unchanged main, not an independent decision
autobot-frontend/src/services/api.ts (#16471) Adjacent-context conflict around a doc comment plus 4 new methods (getSessionPresence, getSessionEvents, getMyInvitations, respondToInvitation); took the union and updated the comment to match the merged code
autobot-backend/api/collaboration.py (#16471) Pure added import (CollaborationEvent); union
autobot-backend/api/collaboration_test.py (#16471) Pure added test function; union
autobot-frontend/src/components/chat/ChatCollaborationPanel.vue (#16471, add/add) Both sides' <script> block were byte-identical; only the template's CSS approach differed (inline Tailwind utility classes vs. a refactored <style scoped> block). Kept main's existing template and CSS, dropping #16471's scoped <style> block — zero behavior change, verified no diff against pre-merge main. Reviewer: please double-check this call, since it does discard part of #16471's own diff (a cosmetic-only part).
autobot-frontend/src/composables/__tests__/useSessionCollaboration.test.ts (#16471, add/add) Diffed both sides directly: incoming was a strict superset of main's copy (new mocks + 3 new test cases, one comma-only change, zero removed lines) — took incoming whole
autobot-frontend/src/composables/useSessionCollaboration.ts (#16471) main's copy was completely untouched by every other member; #16471 substantively rewrote it (593 vs 494 lines, real logic changes, not just additions). Took #16471's version whole. Reviewer: please double-check this call alongside the .vue one above, since the two together mean #16471's composable logic landed in full but its component-level styling did not.
repo_tests/frontend_fragmentation_ratchet_test.py (#16471) Baseline conflict tied to the .vue file's dropped <style> block; kept main's real values (380/5617/9388) since no new styled component was actually introduced — verified against the tree with pytest (53/53 passed)
autobot-backend/mcp_server/autobot_server.py (#16454, rename) Import-block conflict; took the union of #16730's additions (knowledge.search_filters) and #16454's own (autobot_shared.ssot_constants.QueryDefaults), rewriting the auth-throttle import to the renamed mcp_server.auth_throttle path
autobot-backend/services/realtime_mcp_bridge.py (#16454, rename) Docstring-only conflict on _emit_telemetry; main's copy was unchanged, took #16454's more detailed docstring. Git's rename detection correctly carried #16730's edits and its new test file (autobot_server_kb_non_private_16666_test.py) into the renamed mcp_server/ directory — verified, nothing lost
repo_tests/python_file_size_ratchet_baseline.py, scripts/python_file_size_known_large.py (#16454) Auto-merged; verified every mcp_server/*.py entry against real wc -l in the merged tree
Fix commit fix(vehicle): repoint the references #16454's mcp rename stranded (#16449) #16454's rename stranded references main gained afterward. Repointed from mcp.autobot_server import ... to from mcp_server.autobot_server import ... in autobot-backend/api/kb_get_fact_callers_16670_test.py (2 sites) and in autobot-backend/mcp_server/autobot_server_kb_non_private_16666_test.py (2 sites, added by #16730 at the old path). Re-keyed both ("autobot-backend/mcp/autobot_server.py", ...) entries in repo_tests/kb_read_visibility_allowlist.py to the new path, values unchanged. A repo-wide git grep for the old path/import pattern found two remaining hits, both intentional past-tense prose describing the pre-#16449 shadowing bug (autobot-backend/mcp_dependency_not_shadowed_test.py, repo_tests/test_ci_import_smoke_paths_14252.py) — left unchanged

Verification

  • Targeted pytest throughout the merge as a design aid: 53/53 (frontend fragmentation ratchet), 18/18 (collaboration), 12/12 (frontend API contract ratchet), 37/37 (verbatim memory), 41/41 (kb visibility allowlist + get_fact callers + MCP non-private facts).
  • git diff --check clean after every merge (no stray conflict markers).
  • Ratchet baselines checked against real wc -l in the merged tree.
  • Pre-push hook (AUTOBOT_PREPUSH_ALLOW_TIMEOUT=1) ran the full relevant pytest set plus the mcp shadow guard — all passed; push succeeded without --no-verify.
  • Never ran the app or any service; no git stash, commit-tree, or other plumbing used; no commit skipped hooks.

autobot-backend/mcp/ (AutoBot's own MCP server code -- AutoBotMCPServer
and friends) permanently shadowed the real mcp PyPI SDK
(requirements.txt's mcp>=2.1.1) for every module with autobot-backend/
on sys.path: every from mcp.X import Y anywhere in the tree resolved to
the local package's own submodules, never the installed dependency.
Confirmed zero references to mcp.server.*/mcp.client.*/mcp.types
anywhere in autobot-backend/ before this change.

Renamed to mcp_server/, no behaviour change. Every importer updated:
api/autobot_mcp_router.py, api/mcp_token_admin_test.py,
services/realtime_mcp_bridge.py, docs/mcp-server.md's invocation
examples, plus the path-keyed baselines and citations the rename left
stale. No packaging/systemd/ansible entrypoint names the module path
(checked); no open PR touches any of these files (checked against all
54, before starting).

Adds a regression guard: import mcp must resolve to the installed SDK,
never a repo package. Also extracts
RealtimeMCPBridge._emit_telemetry from call_tool's two near-identical
success/error branches -- pre-existing duplication that put the
function over the 65-line function-length guard the moment this
rename touched the file.
…uard (#16449)

Review at acfb301 found three gaps:

1. repo_tests/fixture_fixed_path_teardown_guard_test.py:216 still
   pointed at autobot-backend/mcp/mcp_security_test.py, a directory
   this PR's own rename removed -- red on python-suite shards 2/12 and
   4/12. Fixed to autobot-backend/mcp_server/mcp_security_test.py.
   Also fixed a second stale path the review didn't catch: the module
   docstring in mcp_server/autobot_server.py itself still said "See
   mcp/auth_throttle.py" three lines below the import that already
   correctly said mcp_server.auth_throttle.

2. SSOT/check_baseline_no_growth.sh red. The review flagged this as an
   unconfirmed lead ("I did not root-cause ... treat that as a lead"),
   suggesting a baseline rename procedure. There is no such procedure,
   and check_baseline_no_growth.sh:158-163 says so explicitly: its one
   addition route (byte-identical-to-base-ref) deliberately does NOT
   cover a rename, by design, because the new path is absent at base
   by construction -- no hand-edit could pass it. Root cause was
   actually at the source: mcp_server/autobot_server.py's
   _kb_search(..., limit: int = 10) trips the magic_number
   hardcoded-value rule the moment the rename touches the file. Fixed
   by using QueryDefaults.DEFAULT_SEARCH_LIMIT (the same constant
   seven other call sites already use for this default) instead of
   the literal, and removed the now-unneeded baseline entry -- a fixed
   violation takes its baseline line with it.

3. AC3's guard was mcp-specific; the AC asks for a check that fails on
   ANY future top-level autobot-backend/ package reusing a name this
   repo declares as a dependency. Added
   test_no_top_level_backend_package_shadows_a_declared_dependency,
   reusing production_requirement_names()/_normalize() from
   tools/lint/check_requirements_ci_drift.py (loaded the same way
   repo_tests/requirements_ci_drift_test.py does) rather than a second
   requirements parser. Verified zero collisions on the current tree
   via a standalone snippet before adding the assertion.

The new import (QueryDefaults) pushes autobot_server.py from 948 to
949 lines; ceiling bumped in both ratchet-tracking files to match.

Also fixes the PR body onto this repo's required template headings
and adds a Single-issue rationale section (both flagged by the same
review, "Validate PR template sections" / "Check same-scope batching").
…ething (#16449)

python-suite shard 4/12 has been red on this branch's own
test_import_mcp_resolves_to_the_installed_sdk_not_a_repo_package: `import
mcp` resolves with an empty __file__ (a namespace package, no real
distribution) instead of the installed SDK. Root cause: mcp>=2.1.1 is
declared only in autobot-backend/requirements.txt, which the python-suite
venv never installs from (setup-python-suite/action.yml installs only
requirements-ci.txt + requirements-ci-test.txt and their -r includes; none
of them names mcp, and grep confirms no mcp-adjacent package name appears
either).

requirements_ci_drift_baseline.txt already listed "mcp" as a deliberate
CI/production mismatch, on the rationale "no CI-scoped test importing them
directly" -- true when that entry was written, false now that this branch's
own guard imports it. Per the baseline's own rule ("any entry listed here
that CI now installs... ALSO fails"), the fix is to mirror the floor into
requirements-ci/agent.txt (matching the "MCP protocol for skill
subprocesses" theme of the source declaration) and remove the now-stale
allowlist entry, not add another exemption.
…6449)

Review nit from the delta on 5260523: the guard's own
sys.modules.pop("mcp", None) forced a fresh import but never restored
the module afterward, leaving whatever import mcp produced (or nothing,
on the pre-fix red) installed for every test that ran after it in the
same worker. monkeypatch.delitem restores the original entry at
teardown instead.
…16443)

useSessionCollaboration.ts sent invented message shapes over
globalWebSocketService's /ws/live channel, whose protocol only understands
{action: "subscribe"|"unsubscribe"|"command"|"ping"} -- every message was
silently dropped server-side (api/live_events.py's _handle_message logs
"Unknown live-events action" at DEBUG and moves on). Rewritten onto what
actually exists: REST (api/collaboration.py: invite/remove/participants/
share-secret) and the real presence WebSocket (api/presence_ws.py +
websocket/presence.py's PresenceManager, secured by #16455), using its
generic {"type":"broadcast","payload"} relay for live activity and
secret-share notifications.

Kept the composable's public return shape unchanged wherever the real
backend could support it, which is why ParticipantList.vue,
PresenceIndicator.vue, ActivityFeed.vue and SecretNotifications.vue needed
no code changes at all -- only InviteUserDialog.vue (await the now-async
inviteCollaborator) and ShareSecretDialog.vue (participant-id-aware
shareSecretWithSession; dropped the "expires in" selector, which
Secret.share_with() has no concept of at all) changed.

api/collaboration.py's share_secret_with_session now also calls
presence_manager.broadcast_to_session() after it commits, so connected
participants see the share live -- id/name/sharer only, never the secret
value (pinned by test_share_secret_broadcasts_id_name_and_sharer_only).

Fixed along the way: every component calling useSessionCollaboration()
registered its own onScopeDispose -> leaveSession(), harmless under the old
fake transport but a real bug now that the socket is real -- the first
mounted consumer to unmount would close it out from under every other one
still mounted. Reference-counted instead; the socket closes only when the
last instance disposes.

Retired useActivityTracking.ts (#608/#874): zero real callers, and its
distinct value (local activity tracking + auto-broadcast) is only useful
bundled with a caller that wants both, which none currently does --
useSessionActivityLogger (the local half) remains independently available.

New: ChatCollaborationPanel.vue, a togglable right-side panel in
ChatInterface.vue (mirrors the existing ChatFilePanel pattern), shown for
session.mode === 'collaborative', hosting ParticipantList/ActivityFeed/
SecretNotifications with InviteUserDialog as a modal.

Not in this PR (#16460, filed separately): activity/notification history
is live-only -- nothing is persisted, so a reconnecting client sees nothing
before it joined. pendingInvitations/respondToInvitation are dropped from
the composable entirely rather than stubbed: there is no REST endpoint to
list or respond to a pending invitation despite the model already
supporting it (SessionCollaboration.add_invitation/remove_invitation).

Refs #16429 (ShareSecretDialog AC)
…ation list+respond endpoints (#16460)

Adds a durable copy of the collaboration activity feed and secret-share
notifications (new collaboration_events table + model), so a client that
reconnects or wasn't connected sees what it missed instead of only
live-only history from #16443. websocket/presence.py's generic broadcast
relay now persists 'activity' kind broadcasts alongside forwarding them
live; api/collaboration.py's share_secret_with_session persists
'secret_shared' the same way it already did before this change.

Adds GET /sessions/{id}/events (paginated backfill), GET
/sessions/invitations/mine, and POST /sessions/{id}/invitations/respond
in a new api/collaboration_events.py (kept collaboration.py under the
600-line file-size guard; schemas live in a new schemas_collaboration.py
since schemas_agent.py is frozen at its recorded ceiling). Endpoints wire
to SessionCollaboration's existing add_invitation/remove_invitation.

useSessionCollaboration.ts restores pendingInvitations/respondToInvitation
and backfills recentCollaboratorActivities/secretNotifications on join.

Refs #16460 -- its own UI-surfacing AC is tracked separately as #16470
(no component yet calls pendingInvitations/respondToInvitation).
…16466 (#16460)

#16466 retired integrations/{terminal,file,browser}_tracking.py and
knowledge/activity_types.py as dead code (zero callers, feature never
finished for those three modalities). This Concept -- added on this same
branch -- still listed all four as write-sites; only
utils/activity_tracker.py (its surviving track_desktop_activity) and
integrations/desktop_tracking.py ever actually wrote here.
…ake-shape banlist (#16460, #16443)

Two CRITICAL findings from the code review on d665b52:

- ChatCollaborationPanel.vue's scoped <style> @apply's w-6/h-6 without
  the Tailwind v4 @reference import every other component in this
  directory carries -- production Vite build failed outright with
  CssSyntaxError. Added the same import path MessageItem.vue/
  ChatInput.vue/etc. already use.

- updatePresence()'s real broadcast used payload.kind: 'presence_update',
  which collides with the composable's own new test's FAKE_TYPES banlist
  (the old /ws/live message shapes this composable replaces). Renamed
  the real kind to 'presence' on both the send and receive side -- no
  other file in the tree reads this exact string, so the rename is
  self-contained to this composable.
Auto-regenerated (py3.14) to match the backend and/or SLM backend
schema so the required verify-generated-types gate(s) pass.
Triggered by auto-fix-generated-types.yml.
…#16460)

MEDIUM finding from the review on d665b52: this PR's genuinely new
components/schemas push four fragmentation/contract counts up by a
small amount each -- ChatCollaborationPanel.vue's own styles
(components_declaring_styles +1, distinct_class_names +1,
css_rule_declarations +2), and the new invitation/activity/notification
response shapes (responses +9). Bumped with justification per the
ratchet's own escape hatch for legitimate growth, rather than
consolidating styles/response shapes that don't have an existing
shared home to reuse.
…sh into fr (#16460)

repo_tests/i18n_untranslated_ratchet_test.py caught it: "Collaboration"
and "Notifications" are true cognates in French, but the guard can't
tell that from a lazy copy-paste, and fr already carries the app's
untranslated-string debt at its ceiling. Checked all 11 locales for
the same copy-across on these 6 new keys -- fr was the only one.

- panel.title: "Collaboration" -> "Espace collaboratif" (a heading has
  room to be more descriptive than a bare cognate)
- panel.tabNotifications: "Notifications" -> "Alertes" (a short label
  to match its sibling tabs' brevity; this panel's own register, not
  necessarily every "Notifications" elsewhere in the app)
…ous get_fact(fact_id) (#16710)

get_fact(self, fact_id) is a single, synchronous fact lookup
(knowledge/facts.py) -- it never took a query or returned a list.
Three callers used the wrong tool for the job, either by calling
get_fact() with no args expecting "all facts", or with query= expecting
search results:

- knowledge/knowledge_base_integration_test.py: 8 call sites (more than
  the issue's 3 -- the file also had get_fact() no-arg calls expecting
  "all facts" behavior). query= -> search(query=...); no-arg -> await
  get_all_facts(); fact_id= -> asyncio.to_thread(kb.get_fact, fact_id=...)
  since it's sync. Downstream assertions fixed to match each real return
  shape: get_fact() returns Dict | None (not a 1-item list), and its dict
  key is "fact_id" (not "id"). The P95 latency test's get-latency loop is
  now measured per-fact-id to mirror the store loop above it, instead of
  calling the now-nonexistent "get everything" mode 50 times (which would
  have grown unboundedly across iterations and measured nothing useful).

- autobot-infrastructure/shared/scripts/sync_kb_docs.py: 2 call sites,
  same query= -> search() fix. Its `sys.path.insert` also resolved to the
  wrong directory (two levels up from the script, never autobot-backend,
  where knowledge_base/knowledge_sync_incremental actually live) -- fixed
  to autobot_shared.paths.project_root() / "autobot-backend". No cron,
  systemd, ansible, CI workflow, or Makefile target references this
  script anywhere in the tree (grepped the whole repo); the 2 docs that
  do (librarian-agents-guide.md, knowledge-base-maintenance.md) both
  present it as a manual step ("you MUST run..."), not an automated one.
  Recording that here rather than filing a "wire it in" issue: there is
  no deployment path to wire it into, this is a standalone maintenance
  script invoked by hand.

- docs/developer/ASYNC_MIGRATION_GUIDE.md: its example unit/integration
  tests (test_get_fact_by_id, test_full_knowledge_base_workflow) taught
  the same wrong calls; fixed to the current API. Step 4's earlier
  before/after pipelining example is left as-is -- it illustrates a
  blocking-to-async conversion technique, not a claim about the current
  method signature.

Discovered in scope while fixing the above: knowledge_base_integration_test.py
also had 11 store_fact(text=..., metadata=...) calls -- store_fact's real
signature is store_fact(self, content, metadata=None, fact_id=None), no
text param. Same file, same root cause (the whole file predates the
current KnowledgeBase API and has never run -- its skip was hardcoded to
an unreachable address, see below); renamed text= -> content= at all 11
sites.

Also fixed: the integration test fixture's skip reason hardcoded
"Redis not available at 10.0.0.4:6379" regardless of actual configured
target, so a skip could never be distinguished from a real TypeError this
whole file was hiding. Now reads the host/port from SSOT config
(ssot_config.vm.redis / ssot_config.port.redis).

Found during the #16670 closure audit (#16677); #16670 fixed five other
callers, these were outside its list. tools/tool_registry.py's
get_fact(fact_id=None, query=None) is a genuinely different method that
does take query -- tools/tool_registry_test.py is correct and untouched.
… to the facts present at deploy (#16693)

Owner decisions on #16693: ingested documents keep their reach, now as explicit SYSTEM, and every other ownerless fact stays private.

- knowledge/ingestion_visibility.py recognises each ingestion class by a positive marker that only its writer sets; source_type cannot, since every unmarked fact defaults to manual_upload.
- Migration 20260914_092 marks the facts that have no owner and no visibility at deploy and logs the count.
- At startup, after adopt_legacy_facts, the backfill changes only marked facts, through update_fact.
- index_ownership files an ownerless SYSTEM fact in kb:system:facts.
- Trusted ingestion sites stamp SYSTEM themselves: connectors, the population router, machine-synced and parsed man pages, the repo sync's documentation, and the admin upload.
…ority, and test the anonymous and cross-org refusals (#16278)

Finishes the criteria #16240 left open (#16278, #16279). POST /sync and PATCH
/hardware-priority still wrote created_by="admin"; they now take the actor
from require_settings_admin, which wraps the same check_admin_permission gate.
New tests: the real check_admin_permission refuses an anonymous GET/POST
/api/settings/ with 401 (config untouched), a member with 403, admits an
admin; and a real SQLite database with a user in each of two orgs shows the
tenant-scoped search never returns the other org's user. settings.py drops
a contradictory docstring line, 882 -> 881, ceiling lowered with it.
…nger reads, and scope the admin control (#16278)

Review follow-up on #16469. update_hardware_priority's gate is now
require_settings_admin, so patching api.settings.check_admin_permission did
nothing; the conftest auth stub is what admits the caller, and the comment
says so. The admin control in the real-gate test judges admission only; the
recorded author comes from the stub, which settings_revision_author_test
covers.
Auto-regenerated (py3.14) to match the backend and/or SLM backend
schema so the required verify-generated-types gate(s) pass.
Triggered by auto-fix-generated-types.yml.
…outes through the real gate (#16278)

Re-adds the real-gate test on top of current main: anonymous GET and POST /api/settings/ are refused with 401 before ConfigService is touched, a member gets 403, and an admin write is the 200 control. settings_config_test.py's docstring points to it. Authorship stays with main's TestAnAdmittedWriteRecordsItsAuthor and the #16541 test.
#16278, #16279)

settings_revision_author_test.py (cherry-picked from #16469's branch) proves
the exact same thing settings_sync_hardware_priority_created_by_test.py
already does on main: /sync and /hardware-priority record the real caller,
not "admin" -- that fix and its test landed via #16541 before this branch
was recovered. Confirmed identical coverage: same two test cases
(admin-session-by-username, internal-service-key), same routes, same
assertion (create_revision's created_by kwarg).

user_service_tenant_scope_test.py similarly duplicates
user_service_org_scoping_test.py, already on main via #16506 (which closed
#16279, "org A search finds no org B results" -- a different issue this
branch's history had bundled in). Main's version is the more rigorous of
the two: explicit total-count assertions plus a no-org-context edge case
this file didn't cover at all.

Neither drop loses coverage; both are dead weight from recovering an
orphaned branch whose underlying fixes had already landed elsewhere by
the time it was revived. See PR body for the residual (genuinely new)
scope this branch actually still adds.
The cherry-picked type regen (from the orphaned branch's own stale state)
predates 60+ commits of main history. This PR's only surviving production
change is a 2-line docstring trim in settings.py -- no API shape changed --
so there is nothing to regenerate; matching origin/main exactly is correct.
…ption observes it and decided facts drop out (#16693)

- migration-tests failed on 51ab542: probe-ladder observability found 20260914_092 unobservable, because it only wrote a metadata key.
- An unobservable intermediate revision re-runs on baseline adoption. A re-run would have marked facts stored after deploy, which is the spoofing window the freeze exists to close.
- The candidate flag is now a nullable knowledge_facts.visibility_backfill_candidate column. The add_column is a structural marker the probe observes. The flag is set only in the run that creates the column, so a re-run can never flag a fact stored after deploy.
- Review LOW: the backfill clears the flag on every decided candidate (updated, kept private, skipped), so a later start revisits only failed updates instead of re-walking kept-private facts forever. The flag is row-only, so clearing it moves no projection.
Auto-regenerated (py3.14) to match the backend and/or SLM backend
schema so the required verify-generated-types gate(s) pass.

…ed to the caller (#16701, #16654)

/verbatim-memory/search (api/verbatim_memory.py) checked only that the
caller was signed in -- VerbatimStore.search filtered by session_id when
supplied, never by user, so any signed-in user could search the
autobot_verbatim ChromaDB collection and get back every user's verbatim
conversation chunks. VerbatimStore.search_symbolic (the Redis
inverted-term-index path, currently unwired to any caller but the same
class, same file) had the identical gap.

Fixed by making user_id a required argument on both methods (no default),
applied in the ChromaDB where clause / post-fetch filter -- the same
grant memory/transparency.py's _list_verbatim already applies. Required,
not optional, so a future caller can't silently get every user's chunks
by omitting an argument. The route always passes the authenticated
caller's own user_id (via the established extract_user_context_from_request
helper); there is no admin bypass on this route today -- an admin-wide
search would need its own explicit admin API, which doesn't exist yet.

Also fixed, found while reading the file: DELETE /verbatim-memory/session/
{session_id}'s docstring claimed "in production the middleware
additionally enforces that users can only delete their own sessions", but
nothing in this file (or anywhere findable) enforced that -- any signed-in
user could delete any other user's verbatim session data. Now runs
Depends(validate_session_ownership), the same dependency api/chat_sessions.py
uses throughout for the identical purpose.

MCP path (mcp/autobot_server.py's memory.verbatim_search): this stdio/
JSON-RPC transport authenticates by scope token only ("kb"/"memory"/
"agents" prefixes) -- there is no per-user identity anywhere in its
request handling to scope by, the same shape as _kb_search/_kb_get_document
in the same file (already TRACKED_GAP #16666). Filed #16727 as its own
sub-issue of #16654 rather than force a fix the transport can't support;
this call site passes the new, explicit UNSCOPED_ALL_USERS sentinel and
says why, so the gap is visible and can't spread to a future caller
forgetting to pass user_id. Net-zero line-count change to this frozen
(948-line, #16730/#16701/#16731 all touch it) file: the identity-threading
comment was cut in favor of the constant's own docstring, to leave every
inch of the shared ceiling for the two PRs still to land.

Tested in both directions with a real VerbatimStore over a mocked ChromaDB
collection (not mock-asserts-call-args): search_never_returns_another_users_
chunks / is_symmetric_for_the_other_user, at both the VerbatimStore layer
(memory/verbatim_store_test.py, memory/verbatim_symbolic_test.py) and the
route layer (api/verbatim_memory_16701_test.py). Delete's ownership
dependency is proven wired through a real FastAPI TestClient, not a direct
function call, so a refusal is proven to happen before the handler body
runs.

Refs #16654, #16666, #16727.
Auto-regenerated (py3.14) to match the backend and/or SLM backend
schema so the required verify-generated-types gate(s) pass.
Triggered by auto-fix-generated-types.yml.
…t in README and Platform Model (#16733)

Adds the platform's Why/How/What framing to README.md and docs/architecture/PLATFORM_MODEL.md,
and a new EU_AI_GOVERNANCE.md that cites the real compliance/retention/RBAC code already in
place while stating plainly what governance tooling doesn't exist yet — no compliance
certification is claimed.
Bumps the all-dependencies group with 1 update: [actions/upload-artifact](https://github.com/actions/upload-artifact).

…I Act (#16733)

Extends EU_AI_GOVERNANCE.md with the same cite-what-exists/state-the-gap/claim-no-certification
discipline for two more standards: ISO/IEC 42001 (AI management systems, directly relevant,
same governance primitives as the EU AI Act section) and ISO 14001 (environmental management,
narrower — a structural point about who controls hardware/energy variables, explicitly not a
measured environmental benefit claim). README and PLATFORM_MODEL.md updated to mention ISO 42001
alongside the EU AI Act for consistency across all governance-facing surfaces.
…4001 (#16733)

NIS2 Art. 21(2) security measures mapped to real code: THREAT_MODEL.md (risk analysis),
compliance_manager.py (incident-handling audit log), backup.py + verify-backup-restore.yml
(business continuity, verified restore not just backup), dependabot.yml (supply chain),
secrets_vault.py (cryptography/encryption policy via envelope-encrypted DEKs), user_management/
(access control), and a real MFA model (UserMFA, mfa_enabled) rather than a placeholder field.
States the real gaps plainly: no SECURITY.md/vulnerability-disclosure policy at repo root, no
incident-reporting workflow mapped to NIS2's 24h/72h/1-month timeline, and no NIS2 applicability
determination (that depends on the operator's sector/size, not on AutoBot). Doc renamed to
"EU AI Act, NIS2 & Governance Fit"; README and PLATFORM_MODEL.md updated to match everywhere.
…TEM facts indexed (#16693)

Conflicts after vehicles 2e/2f:
- knowledge/facts.py: #16705 added "and owner_id" to the ownership-index call's guard.
  Kept this branch's guard without it: index_ownership itself returns False for an
  ownerless fact and adds an ownerless SYSTEM fact to kb:system:facts, which the
  owner_id check would skip. A missing ownership manager still takes the #689
  fallback (#16685's test covers it).
- python_file_size ratchet and known-large lists: every entry set to the merged
  tree's wc -l (all 488 entries in each file checked).
…omparable string (#16701)

37's #16732 review: the sentinel was a plain string
("__unscoped_all_users__") compared with ==/!=. extract_user_context_from_request
falls back to the caller's username when a token has no user_id claim, and
usernames are validated against ^[a-zA-Z0-9_]+$ -- a pattern the old sentinel
text satisfies. A user actually named "__unscoped_all_users__" would have
equaled the sentinel and searched every other user's verbatim chunks.

UNSCOPED_ALL_USERS is now an instance of a dedicated, non-str sentinel type;
search()/search_symbolic()/_rank_symbolic_candidates() compare it with `is`,
never `==`, so no string a caller supplies can ever match it. Added a test
proving a user_id literally equal to the old sentinel text stays scoped to
their own chunks.

📝 Walkthrough

Walkthrough

The change adds durable collaboration history and invitation APIs, SYSTEM knowledge-document visibility and backfill, MCP package and access updates, per-user verbatim-memory scoping, workflow action pins, and related tests and documentation.

Changes

Platform and workflow updates

Layer / File(s) Summary
Workflow and repository contracts
.github/workflows/*, README.md, docs/*, requirements-ci/agent.txt, repo_tests/*
Artifact uploads now use actions/upload-artifact@v7.0.1. Documentation and repository references use mcp_server. Governance documentation and the MCP dependency declaration were added or updated.

Collaboration history and invitations

Layer / File(s) Summary
Durable event storage and writes
autobot-backend/models/collaboration_event.py, autobot-backend/migrations/versions/20260912_092_collaboration_events.py, autobot-backend/api/collaboration.py, autobot-backend/websocket/presence.py
PostgreSQL stores collaboration events. Secret sharing and activity broadcasts create event rows.
REST API and frontend integration
autobot-backend/api/collaboration_events.py, autobot-backend/api/schemas_collaboration.py, autobot-frontend/src/services/api.ts, autobot-frontend/src/composables/useSessionCollaboration.ts
The API lists session events, lists invitations, and accepts or declines invitations. The frontend backfills events after joining and manages pending invitations.

Knowledge visibility and access

Layer / File(s) Summary
Visibility classification and ingestion stamping
autobot-backend/knowledge/ingestion_visibility.py, autobot-backend/api/knowledge_population.py, autobot-backend/knowledge/connectors/base.py, autobot-backend/services/man_page_parser.py
Trusted document ingestion paths mark unclaimed documents with SYSTEM visibility. Existing ownership and visibility claims remain unchanged.
Candidate migration and backfill
autobot-backend/migrations/versions/20260914_092_kb_visibility_backfill_candidates.py, autobot-backend/knowledge/fact_store.py, autobot-backend/knowledge/fact_projection.py, autobot-backend/knowledge_factory.py
Existing ownerless facts are marked as candidates. The backfill classifies candidates, updates eligible documents, records outcomes, and clears processed flags.
MCP and ownership indexes
autobot-backend/knowledge/search_filters.py, autobot-backend/mcp_server/autobot_server.py, autobot-infrastructure/shared/mcp/tools/knowledge-base-mcp/autobot_knowledge_mcp/embedded.py, autobot-backend/knowledge/ownership_index.py
MCP knowledge searches and document retrieval exclude private and quarantined facts. SYSTEM facts are written to kb:system:facts.

MCP package and security updates

Layer / File(s) Summary
Package rename and dependency guard
autobot-backend/mcp_server/*, autobot-backend/mcp_dependency_not_shadowed_test.py, autobot-backend/api/autobot_mcp_router.py
The repository MCP package uses mcp_server, allowing import mcp to resolve to the installed SDK. Imports, tests, and path references were updated.
MCP throttling and security coverage
autobot-backend/mcp_server/auth_throttle.py, autobot-backend/mcp_server/mcp_security_test.py, autobot-backend/mcp_server/mcp_cache_test.py
Pre-authentication throttling, cache coverage, path controls, input validation, size limits, and registry security tests were added or updated.

Verbatim memory and supporting tests

Layer / File(s) Summary
User-scoped searches
autobot-backend/memory/verbatim_store.py, autobot-backend/api/verbatim_memory.py
Verbatim searches now require a user identifier and apply user filtering. Session deletion uses the session-ownership dependency.
Regression and integration coverage
autobot-backend/memory/*test.py, autobot-backend/api/verbatim_memory_16701_test.py, autobot-backend/tests/api/test_settings_anonymous_16278.py, autobot-backend/knowledge/knowledge_base_integration_test.py
Tests cover cross-user isolation, ownership enforcement, real settings permissions, and the current knowledge-base retrieval API.

224-224.

In `@autobot-backend/api/collaboration_events.py`:
- Around line 100-104: Update the collaboration event pagination query to use a
deterministic compound cursor: order by CollaborationEvent.timestamp and
CollaborationEvent.id, and make the before cursor carry both values. Change the
boundary predicate to exclude only records at or before that exact timestamp/id
position, preserving limit pagination without omitting events sharing a
timestamp.
- Around line 99-100: Update the collaboration event persistence and retrieval
flow around CollaborationEvent so secret_shared events are visible only to their
intended recipients: persist recipient scope and include it in the history query
after the existing VIEWER check, or omit sensitive secret metadata from
session-wide history. Preserve access to non-sensitive events and existing
session filtering.
- Around line 225-237: The invitation acceptance flow around _get_session_collab
and add_collaborator must validate my_invitation’s expires_at before granting
access. Reject expired invitations with the existing not-found or appropriate
HTTP error response, and only call add_collaborator after confirming the
invitation is still valid.

In `@autobot-backend/api/collaboration.py`:
- Line 157: Update the event persistence helper around db.flush() to use a
nested transaction/savepoint, ensuring a flush failure rolls back only the event
write and does not invalidate the outer transaction used by
share_secret_with_session. Preserve best-effort event handling so the share
commit succeeds when event persistence fails, and add a test covering a flush
exception followed by a successful share commit.

In `@autobot-backend/knowledge/fact_projection.py`:
- Around line 303-306: The backfill path in _backfill_one_document must claim
candidates conditionally at the durable-store boundary, requiring BACKFILL_MARK
and the complete unclaimed predicate in a dedicated update rather than
unconditional update_fact or _durable_update_or_adopt persistence fallback.
Treat a failed predicate as skipped, and update Redis, ChromaDB, and ownership
projections only after success; clear the backfill flag after handling the claim
result.

In `@autobot-backend/knowledge/search_filters.py`:
- Around line 231-234: Update the visibility/access filtering logic around the
NON_PRIVATE_VISIBILITY and NON_PRIVATE_ACCESS predicates so explicit private,
shared, group, or organisation visibility always rejects a fact before
access_level is considered. Apply the same precedence in both the ChromaDB
clause and the post-filter, and add a parameterized test covering conflicting
metadata such as private visibility with general access.

In `@autobot-backend/mcp_server/auth_throttle.py`:
- Around line 271-278: Update get_pre_auth_throttle and PreAuthThrottle usage so
the global ceiling is enforced through a shared atomic backend such as Redis,
rather than the process-local _throttle singleton; alternatively enforce the
same limit at the trusted ingress. Preserve atomicity and ensure all Uvicorn
workers observe one shared ceiling.
- Around line 223-225: The pre-authentication lockout path must not key failures
on the spoofable result of get_client_ip(request). Update mcp_tool_call and
record_failure to use the transport peer identity or a canonical identity
derived from the trusted proxy chain, while preserving the existing lockout
threshold and duration behavior.

In `@autobot-backend/mcp_server/mcp_cache_test.py`:
- Line 287: Remove the `@pytest.fixture` decorator from
test_environment_variable_loading so pytest collects and executes it as a test,
preserving its existing default TTL and enabled-state assertions.

In `@autobot-backend/memory/verbatim_store.py`:
- Around line 57-62: The verbatim search path must require a dedicated
privileged authorization scope before accepting UNSCOPED_ALL_USERS. Update the
MCP dispatcher and the handler for memory.verbatim_search to permit all-users
searches only for authorized administrators or trusted stdio callers, while
preserving per-user searches and rejecting broad memory-scope or unauthorized
Redis/JWT requests.

In
`@autobot-backend/migrations/versions/20260914_092_kb_visibility_backfill_candidates.py`:
- Line 39: Update the migration’s down_revision declaration to depend on
20260912_092, restoring a single Alembic head while preserving the existing
migration identity.

In `@autobot-backend/websocket/presence.py`:
- Line 259: Update the persistence flow around the WebSocket activity payload so
the stored username comes only from the authenticated server-side identity,
never payload.get("username"). Use None when that identity is unavailable, and
adjust the persistence test to avoid requiring a client-supplied username while
preserving the real user_id.

In `@autobot-frontend/src/composables/useSessionCollaboration.ts`:
- Around line 298-300: Update the session-event backfill flow around
getSessionEvents and the event insertion loop to clear shared event arrays
whenever the active session changes, removing entries from the previous session.
Before every mutation of those arrays, verify that currentSessionId.value still
equals the requested sessionId so stale responses cannot add session A events
after switching to session B.
- Around line 328-330: Update _backfillEvents, refreshPendingInvitations, and
respondToInvitation so request failures remain distinguishable from legitimate
empty data or unsuccessful responses: use a typed result, explicit error state,
or rethrow to a handling caller. Do not swallow errors by resolving with
empty/default values or false, and preserve the existing logger context while
exposing failure information to callers.

In `@docs/architecture/EU_AI_GOVERNANCE.md`:
- Around line 39-41: Update the EU AI Act timeline in the introductory
obligations paragraph to distinguish the high-risk application dates: use 2
December 2027 for Annex III high-risk systems and 2 August 2028 for Annex I
product-embedded high-risk systems, retaining 2 August 2026 only for provisions
that genuinely apply on that date.

In `@docs/research/connector-credential-egress-audit.md`:
- Line 48: Update the displayed MCP source path in the documentation link to use
mcp_server/autobot_server.py:560-570, matching the existing link target and
removing the obsolete mcp/autobot_server.py label.

Use a deterministic compound pagination cursor.

The query orders and filters only by timestamp. If the page boundary contains multiple events with the same timestamp, the strict timestamp &lt; before predicate omits the remaining events permanently.

Order by timestamp and id. Include both values in the cursor and predicate.

Do not persist the author name from the WebSocket payload.

message is parsed from client WebSocket text, and payload["username"] is client-controlled. A session participant can send an activity with another user's name. The durable history can then display a false author, even though user_id retains the real actor.

Resolve the username from the authenticated server-side identity, or store None until that identity is available. Update the persistence test so it does not require a client-supplied username.

Bind backfill results to the active session.

A request for session A can complete after the user joins session B. The function then inserts session A events into the shared current-session arrays. Existing entries also remain when the session changes.

Clear the event arrays when the active session changes. Before each mutation, also confirm that currentSessionId.value === sessionId.

Keep API failures distinguishable from valid results.

_backfillEvents and refreshPendingInvitations resolve normally after a failed request. respondToInvitation converts a request failure to false. Callers cannot distinguish these failures from empty data or a valid unsuccessful response.

Return a typed result, update an explicit error state, or rethrow to a caller that handles the failure.

As per path instructions, “a caught error that resolves to an empty or default value” must stay distinguishable from a legitimate empty result.

223-225: 🔒 Security & Privacy | 🛡️ Analyzed with Security Review | 🟠 Major | 🏗️ Heavy lift

Denial of Service

Reachability: External
Exploitability: Moderate
CWE: CWE-400 — Uncontrolled Resource Consumption

Use a non-spoofable identity for the pre-authentication lockout key.

mcp_tool_call passes get_client_ip(request) to record_failure. With the shipped appending proxy configuration, get_client_ip selects the caller-controlled leftmost X-Forwarded-For value. An attacker can therefore lock a chosen address before token validation. Use the transport peer or a canonical trusted proxy-chain identity instead.

Security Misconfiguration

Reachability: External
Exploitability: Moderate
CWE: CWE-799

Use a shared global throttle across backend workers.

The supported backend service runs four Uvicorn workers. Each worker creates its own in-memory PreAuthThrottle, so the global ceiling can be multiplied across workers. Store the global ceiling in an atomic shared backend such as Redis, or enforce it at the trusted ingress.

Collect the default-regression check as a test.

@pytest.fixture prevents test_environment_variable_loading from being collected as a test. No test requests this fixture, so the default TTL and enabled-state assertions never run.

In `@autobot-backend/api/collaboration_events.py`:
- Around line 100-104: Update the collaboration event pagination query to use a
deterministic compound cursor: order by CollaborationEvent.timestamp and
CollaborationEvent.id, and make the before cursor carry both values. Change the
boundary predicate to exclude only records at or before that exact timestamp/id
position, preserving limit pagination without omitting events sharing a
timestamp.
- Around line 99-100: Update the collaboration event persistence and retrieval
flow around CollaborationEvent so secret_shared events are visible only to their
intended recipients: persist recipient scope and include it in the history query
after the existing VIEWER check, or omit sensitive secret metadata from
session-wide history. Preserve access to non-sensitive events and existing
session filtering.
- Around line 225-237: The invitation acceptance flow around _get_session_collab
and add_collaborator must validate my_invitation’s expires_at before granting
access. Reject expired invitations with the existing not-found or appropriate
HTTP error response, and only call add_collaborator after confirming the
invitation is still valid.

In `@autobot-backend/api/collaboration.py`:
- Line 157: Update the event persistence helper around db.flush() to use a
nested transaction/savepoint, ensuring a flush failure rolls back only the event
write and does not invalidate the outer transaction used by
share_secret_with_session. Preserve best-effort event handling so the share
commit succeeds when event persistence fails, and add a test covering a flush
exception followed by a successful share commit.

In `@autobot-backend/knowledge/fact_projection.py`:
- Around line 303-306: The backfill path in _backfill_one_document must claim
candidates conditionally at the durable-store boundary, requiring BACKFILL_MARK
and the complete unclaimed predicate in a dedicated update rather than
unconditional update_fact or _durable_update_or_adopt persistence fallback.
Treat a failed predicate as skipped, and update Redis, ChromaDB, and ownership
projections only after success; clear the backfill flag after handling the claim
result.

In `@autobot-backend/knowledge/search_filters.py`:
- Around line 231-234: Update the visibility/access filtering logic around the
NON_PRIVATE_VISIBILITY and NON_PRIVATE_ACCESS predicates so explicit private,
shared, group, or organisation visibility always rejects a fact before
access_level is considered. Apply the same precedence in both the ChromaDB
clause and the post-filter, and add a parameterized test covering conflicting
metadata such as private visibility with general access.

In `@autobot-backend/memory/verbatim_store.py`:
- Around line 57-62: The verbatim search path must require a dedicated
privileged authorization scope before accepting UNSCOPED_ALL_USERS. Update the
MCP dispatcher and the handler for memory.verbatim_search to permit all-users
searches only for authorized administrators or trusted stdio callers, while
preserving per-user searches and rejecting broad memory-scope or unauthorized
Redis/JWT requests.

In
`@autobot-backend/migrations/versions/20260914_092_kb_visibility_backfill_candidates.py`:
- Line 39: Update the migration’s down_revision declaration to depend on
20260912_092, restoring a single Alembic head while preserving the existing
migration identity.

In `@autobot-backend/websocket/presence.py`:
- Line 259: Update the persistence flow around the WebSocket activity payload so
the stored username comes only from the authenticated server-side identity,
never payload.get("username"). Use None when that identity is unavailable, and
adjust the persistence test to avoid requiring a client-supplied username while
preserving the real user_id.

In `@autobot-frontend/src/composables/useSessionCollaboration.ts`:
- Around line 298-300: Update the session-event backfill flow around
getSessionEvents and the event insertion loop to clear shared event arrays
whenever the active session changes, removing entries from the previous session.
Before every mutation of those arrays, verify that currentSessionId.value still
equals the requested sessionId so stale responses cannot add session A events
after switching to session B.
- Around line 328-330: Update _backfillEvents, refreshPendingInvitations, and
respondToInvitation so request failures remain distinguishable from legitimate
empty data or unsuccessful responses: use a typed result, explicit error state,
or rethrow to a handling caller. Do not swallow errors by resolving with
empty/default values or false, and preserve the existing logger context while
exposing failure information to callers.

In `@docs/architecture/EU_AI_GOVERNANCE.md`:
- Around line 39-41: Update the EU AI Act timeline in the introductory
obligations paragraph to distinguish the high-risk application dates: use 2
December 2027 for Annex III high-risk systems and 2 August 2028 for Annex I
product-embedded high-risk systems, retaining 2 August 2026 only for provisions
that genuinely apply on that date.

In `@docs/research/connector-credential-egress-audit.md`:
- Line 48: Update the displayed MCP source path in the documentation link to use
mcp_server/autobot_server.py:560-570, matching the existing link target and
removing the obsolete mcp/autobot_server.py label.
