fix(gateway): preserve owner isolation when thread metadata is missing (#5484)
* fix(gateway): preserve owner isolation when thread metadata is missing

Follow-up to the #5448 review P1 (post-merge finding): owner_check=True
also authorizes threads whose meta row is missing (legacy compatibility)
or NULL-owner (shared/pre-auth data). _run_scope_user_id returned None
for every trusted internal caller, which dropped the only remaining
per-user filter on those threads and let an internal caller acting for
owner A read owner B's persisted runs.

_run_scope_user_id now takes the thread_id and consults the thread meta
store: when an existing meta row establishes ownership, the authorized
thread's runs are still read unfiltered (merged #5448 semantics,
including owner-header-less internal callers); when the meta row is
missing or NULL-owner, the filter falls back to the acting owner's raw
stamp (the exact value start_run writes) — or the synthetic "default"
identity without an owner header — so cross-user runs stay hidden.

Isolation coverage uses the real MemoryThreadMetaStore with no metadata
row (and a NULL-owner row) plus another user's persisted run: /runs and
/runs/page must be empty and /runs/{run_id} must 404 for internal
callers, while an established-ownership thread keeps the unfiltered
read.

* fix(gateway): gate run-scoped sub-resource reads for internal callers

Review follow-up on #5484: the P1 owner-isolation class remained
reachable through run-scoped sibling reads that apply no per-user filter
at all — /runs/{run_id}/messages, /events, /join, /stream and
/workspace-changes query by (thread_id, run_id) directly, so on
missing/NULL-owner threads an internal caller acting for owner A could
still read owner B's run content by id (verified 200 at the previous
head).

- Extract _thread_ownership_established (shared meta-row check) and add
  _require_run_visible_to_scope: for internal callers on threads without
  established ownership, the run's own user_id stamp must match the
  acting owner's raw value (or the legacy "default" stamp) or the read
  404s. Established-ownership threads and every non-internal caller keep
  their existing thread-scoped semantics.
- Wire the gate into join, stream, messages, events and
  workspace-changes; reword the now-stale messages comment to track the
  new scoping semantics.

Regression tests: sub-resource reads 404 for a mismatched internal
owner while the matching owner reads them normally, and the owner-less
fallback branch (synthetic "default" filter on missing-meta threads) is
pinned. Red confirmed against the pre-gate head.

* fix(gateway): gate cancel and artifact archive for internal callers

Review follow-up on #5484 round 2: POST /cancel resolved runs unscoped
(require_existing=True only closes the missing-meta case — NULL-owner
meta rows still pass), so an internal caller acting for a different
owner could interrupt another owner's active run on a shared thread
while /join and /stream were already gated. The archive manifest and
download pair likewise leaked the other owner's delivered-file count
and a 200-vs-409 delivery oracle on NULL-owner threads (missing-meta
threads were already denied by require_existing=True).

All three routes now call _require_run_visible_to_scope; its docstring
records the extended coverage. NULL-owner-thread regression tests pin:
a mismatched internal owner gets 404 from cancel, manifest and archive
download, while the acting owner reaches the real conflict path (409 on
a terminal run) and reads the manifest (file_count 2).

* fix(gateway): tolerate state-less request stand-ins in the scope helpers

The new owner-isolation gate and _run_scope_user_id read request.state
directly, which crashed the FakeRequest-based unit suites for the run
events, workspace-changes and scope endpoints (backend-unit-tests shards
1/2/4 on #5484). Read the state object defensively first: a request
without state is simply not an internal caller, so those paths keep
their pre-gate semantics.

* fix(gateway): scope the thread token-usage aggregate by owner

Review follow-up on #5484 round 4: GET /{thread_id}/token-usage called
aggregate_tokens_by_thread(thread_id) with no user filter at all, so on
missing/NULL-owner threads an internal caller acting for owner A read
owner B's spend, model names, run count and (with include_active=true)
live activity; the NULL-owner variant reached browser sessions too.
build_context_usage's latest-model lookup was unfiltered as well.

aggregate_tokens_by_thread gains an optional user_id (mirroring
list_by_thread: explicit None = unfiltered, AUTO resolves the contextvar)
in the memory store, the SQL repository and the store base;
build_context_usage/_resolve_thread_model_name thread the scope through
the latest-run lookup; the token-usage endpoint passes
_run_scope_user_id's value. Established-ownership threads aggregate
unfiltered as before; shared/missing-meta threads narrow to the acting
identity. Stale helper-test comment reworded after the #5482 merge
adaptation.

* test(gateway): pin the unfiltered aggregate on established-ownership threads

Review follow-up on #5484 round 5: the established-ownership branch of
the token-usage scoping (store receives user_id=None) was the only
unpinned half of the contract — the round-4 call-assertions never set
app.state.thread_store, so their None came from the user-less stand-in
path. test_token_usage_unfiltered_on_established_ownership_for_
internal_callers seeds an established meta row plus runs stamped by two
different identities and asserts the totals fold (166 = 111 + 55);
together with the isolation tests it now catches both failure modes
(always-stamp narrowing and always-None leak).

fix(gateway): scope edit/regenerate helper fallbacks by data identity (#5483)
The message edit/regenerate prepare chain resolves source runs through
_resolve_run_id_for_message, _require_successful_source_run and
_find_interrupted_target_run_id, which filtered by the authorization
identity (get_current_user) — the same conflation fixed for the runs and
messages read endpoints in #5448, left out of scope there. For trusted
internal callers the authorization identity never matches the raw
owner-stamped run rows, so regenerate/edit-regenerate prepare fails with
409 on threads the caller is authorized on (#5482).

The three helpers now resolve their filter id through _run_scope_user_id
as well; both prepare endpoints keep their owner_check=True
authorization and browser/API sessions keep the per-user filter.

Regression tests extend test_thread_runs_internal_scope.py to the helper
fallback paths: internal callers resolve raw-owner-stamped runs
(including the interrupted-run and status-409 paths), browser sessions
keep the per-user filter and 409 on cross-user runs.

fix(gateway): scope runs read endpoints by data identity, not authorization identity (#5448)
* fix(gateway): scope runs read endpoints by data identity, not authorization identity

Trusted internal callers are authorized as a synthetic internal user
(id "default", or the make_safe_user_id-normalized owner with an owner
header), while start_run stamps run rows with the raw trusted-owner value.
list_runs / get_run / list_runs_page filtered by the authorization identity,
so the store-side user filter never matched and internal callers always saw
an empty runs list (or 404) for threads they are authorized to read.

The three read endpoints now resolve their filter id through
_run_scope_user_id: internal-role callers skip the per-user filter (thread
visibility is already authorized by owner_check=True), and browser/API
sessions keep the existing per-user filter unchanged.

Regression tests cover both identities across the three endpoints (list,
keyset page, single get) with a MemoryRunStore seeded with mixed-owner rows;
without the fix the four internal-caller cases fail while the
browser-session isolation case passes.

* fix(gateway): route the message read endpoints through the same data-identity scoping

Review follow-up on #5448: list_thread_messages and list_thread_messages_page
resolved get_current_user and passed it as the data filter to the event-store
scan, hidden-run lookups, turn-duration injection and the feedback queries —
the same authorization-vs-data identity conflation fixed for the runs
endpoints, leaving the #5437 empty-read symptom in place for lossy owner
values. Both endpoints now resolve their filter id through
_run_scope_user_id as well.

Regression tests extend to the two message endpoints, asserting the resolved
filter identity at the runs-store and feedback-repo boundaries (None for
internal callers, the session user id for browser sessions).

* fix(feedback): deterministic per-run collapse for unfiltered feedback reads

Review follow-up on #5448: with _run_scope_user_id returning None for
internal callers, the feedback lookups now receive an explicit-None user id,
which skips the user_id WHERE in FeedbackRepository. On shared/NULL-owner
threads several browser users can hold feedback on the same run, and
list_by_thread_grouped / list_by_run_ids collapsed rows per run_id via a
dict comprehension over unordered results — the feedback attached to the
last AI message would be an arbitrary user's row.

Both methods now order by created_at ASC with feedback_id as the tie-break,
so the collapse deterministically keeps the most recently created feedback.
_run_scope_user_id's docstring now documents that the resolved id also
scopes feedback and event-store reads, not just run rows.

Regression test seeds multi-user feedback on one run and asserts the
collapse outcome is stable across repeated unfiltered reads.

* docs(feedback): the collapse keeps the most recently written feedback

created_at is refreshed on upsert, so the surviving row per run is the
most recently written (created or updated), not the most recently
created — align both docstrings with the ordering key's actual semantics.
