docs(gateway): bring the gateway guide back under its hard budget (#5707)
backend/app/gateway/AGENTS.md reached 49,155 bytes against the
49,152-byte hard limit, so tests/test_agent_guidance_check.py fails on
main for every change, not just ones that touch the file.

This trims wording I added to the Uploads row in #5547, #5611 and #5673
rather than anyone else's documented invariants: the delete clause keeps
both facts — symlinks 404, a converted .md is kept — without restating
that the 404 matches GET /list.

That clears the overage with 13 bytes to spare, which is not much. The
file is effectively full, so the next addition needs a real slimming
pass or a budget decision.

fix(uploads): stop deleting a converted companion we cannot prove we wrote (#5673)
* fix(uploads): stop deleting a converted companion we cannot prove we wrote

Conversion names a document's Markdown companion after the document's
stem and falls back to a _N suffix when that name is already taken, so
the .md beside a document may belong to another document sharing the
stem, or to the user. Delete removed it anyway: uploading a.docx and
a.pdf produces a.md and a_1.md, and deleting a.pdf destroyed a.docx's
companion while orphaning a.pdf's own.

Delete now removes only the file it was asked to remove. The companion
stays listed and can be deleted on its own. Orphans are the cost of not
guessing; issue #5672 covers giving companions a provable owner, which
is what a safe cleanup needs, along with the two related readers that
still guess (the outline injected for a document and the agent's file
listing).

convertible_extensions loses its last use and is dropped from the
signature and both call sites. The gateway router keeps importing
CONVERTIBLE_EXTENSIONS for the ingestion bridge and now declares it in
__all__, where that module documents its re-exports.

fix(uploads): convert the bytes we wrote, not the name they landed under (#5611)
* fix(uploads): convert the bytes we wrote, not the name they landed under

Document conversion re-opened the upload by name after it was already
visible in the thread's uploads directory: the Gateway converted the
committed file_path, and DeerFlowClient converted the copy it had just
placed there. That directory is writable from local and AIO sandboxes,
so a process watching it can replace the name with a symlink in the
window between the upload landing and the converter opening it. The
converter then reads whatever host file the link points at and writes
that content back into the thread as the .md companion, which the
sandbox can read. Reproduced end to end on both paths with a real xlsx:
the companion came back holding the host file's rows.

The Gateway now duplicates the descriptor of the staged file before the
link-commit, copies those bytes into a private directory outside the
uploads tree, and converts there. A descriptor cannot be redirected by
replacing a name, so the conversion input is the content this request
wrote. The client converts the caller's own source file instead of the
copy in uploads; the source is the file the caller handed in, which the
sandbox cannot reach.

Both already wrote the companion without following a symlink, so only
the read side changes. The uploads directory still receives exactly the
same files.

* docs(changelog): note upload conversion source fix (#5611)

* fix(uploads): close the conversion descriptor when staging its copy fails

Review follow-up. The private directory for the conversion copy was
created before the try that owns the duplicated descriptor, so a failure
there — a full or unwritable temporary filesystem — propagated without
closing it. The upload's own cleanup only unlinks the committed name and
releases the sandbox lease, so the descriptor stayed open for the life of
the process and kept the unlinked staged bytes allocated with it; repeated
failures accumulated both.

Directory creation now happens inside that try, and the finally removes
the directory only once it exists.

* fix(uploads): keep the conversion descriptor owned across cancellation

Review follow-up. run_file_io cannot interrupt its worker, so cancelling
the await around os.dup only abandoned the result: the duplicate was
created moments later with nothing left to close it, and it pinned the
staged bytes of an upload whose name the cleanup had already unlinked.
Cancellation after the duplication was just as leaky, because the
commit-path handler caught Exception and CancelledError is not one.

The duplication now runs as its own task, shielded from the caller's
cancellation, and closes its own result when the caller is gone by the
time the worker finishes. The commit path catches BaseException, closing
the descriptor it already owns before re-raising.

Both windows are pinned: one test stalls the duplication worker after it
allocates and cancels ingestion, the other stalls the commit so the
cancellation lands while the descriptor is owned.

* fix(uploads): drain the conversion copy so its descriptor always closes

Review follow-up. The copy worker owns the duplicated descriptor and
closes it in its own finally, but a bare await let a cancellation cancel
the executor job while it was still queued: the worker never ran, so that
finally never ran either, and the enclosing scope had already handed
ownership away and saw None. Draining also keeps a late worker from
writing into a private directory this scope has since removed.

The copy now goes through await_drained, the shield-and-drain helper the
Gateway already uses for offloads that must not be abandoned mid-flight.
Pinned by a test that holds the copy job queued, cancels ingestion, then
releases it and requires the descriptor to come back closed.

fix(uploads): delete the requested upload, not a symlink's target (#5547)
* fix(uploads): delete the requested upload, not a symlink's target

delete_file_safe resolved the requested path before unlinking it. The
uploads directory is writable from local and AIO sandboxes, so a
symlink planted under an upload name was followed: deleting alias.pdf
removed the victim.pdf it pointed to, and the companion cleanup then
removed victim.md, while the link itself survived and the call reported
"Deleted alias.pdf". A link resolving outside the directory was already
refused by the traversal check, so the damage stayed inside the
thread's uploads.

The function now checks and unlinks the requested entry itself and
treats a symlink as not found, the same way list_files_in_dir already
hides it. unlink() never follows the final component, so a file swapped
for a link between the check and the unlink removes only the link.
Tests cover the helper, the Gateway DELETE route, and
DeerFlowClient.delete_upload.

feat(authz): filter per-caller skill visibility on the skill listing surfaces (#4063 Phase 4) (#5489)
* feat(authz): filter per-caller skill visibility on the listing surfaces (#4063 Phase 4)

GET /api/skills, GET /api/skills/custom, and GET /api/skills/{name} now
filter the user-scoped catalog through filter_resources(principal,
"skill", ...) — mirroring list_models. Anonymous callers are unfiltered;
provider errors follow authorization.fail_closed (fail-closed -> empty
listing / 404, fail-open -> full listing). An invisible skill on the
detail surface returns the standard 404 so the endpoint cannot become an
existence oracle the filtered list closed. Management endpoints stay
require_admin_user-gated; runtime activation is #4541's layer.

resolve_skill_authorization joins resolve_model_authorization as a thin
sibling over a shared _resolve_route_scoped_authorization core.

* docs(authz): reflect per-caller skill visibility in OpenAPI metadata and implementation notes (#5489)

Address the two non-blocking review findings on #5489:

- The three user-facing GET routes (/skills, /skills/custom,
  /skills/{name}) now say in their /docs-visible descriptions that
  authorization filters the response (hidden skills 404 on detail).
- Add the dated Phase 4 decision-log entry to the authorization
  implementation notes, per the convention of every prior merged
  authz PR: listing-visibility semantics, the 404-vs-403
  existence-oracle rationale, anonymous-caller behavior, and the
  #4541 rebase reconciliation points (config.example.yaml roles
  comment + this file's decision log).

* docs(authz): move route guidance into Gateway module guide

fix(goal): wait for the user when a turn ends on an unanswered question (#5467)
* fix(goal): wait for the user when a turn ends on an unanswered question

ask_clarification and the sandbox network prompt put their question in a
ToolMessage and end the graph. The goal evaluator only reads human and AI text,
so it never saw the question, judged the goal not met, and the worker queued a
hidden continuation telling the agent to keep going while the card was still
open. The agent could then act on a guess before the user answered.

Stand the goal down with blocker needs_user_input, without calling the
evaluator, when the trailing tool results include a human input request.

feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash (#5443)
* feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash

Implements docs/superpowers/specs/2026-09-12-projects-mvp-phase2-design.md
(issue #5160, tracker #5129) in the slice order of the spec's §16.

Slices:
- A: ProjectsConfig + write-time 422 UTF-8 byte cap; PROJECT_CONTEXT_KEY
  admission pinning (both server-owned sets + worker hoist); latest-only
  request-scoped <project> block via DynamicContextMiddleware
  wrap_model_call/awrap_model_call (idempotent reassembly, reserved ID
  prefix + marker + provenance, never persisted); journal audit
  fingerprints; Instructions tab.
- B: ProjectDocumentRow + migration 0023; ProjectDocumentRepository with
  locked check-and-set; hash-qualified immutable shelf storage with
  Paths helpers; upload/list/content/delete-to-trash routes; project
  delete trashes the shelf in-transaction; request-scoped bounded
  <documents> index with honest count/shown + actionable overflow note;
  list_project_documents/read_project_document tools registered only on
  pinned runs; PAT allowlist + drift guards; blocking-IO anchors.
- C: shared thread-upload ingestion service (uploads router refactored to
  parity); POST from-thread with provenance; attach-to-thread with
  lock-staged copy (archived source allowed); read-only thread-files
  view with per-group truncation reporting.
- D: restore (restored/merged/not_found/no_target/content_missing; no
  file moves), purge (continuous row lock across unlink/delete/commit,
  retryable on FS errors), retention sweep (lazy + startup, 24h orphan
  guard, row-side reconciliation never deletes).
- E: Documents tab (shelf + conversation-files browser, provenance,
  archived banner, content-missing rows), /workspace/trash route,
  sidebar entry, composer attach handoff, i18n (en-US/zh-CN), e2e mocks
  + specs.

Review hardening folded in (10 rounds, all with tests):
- force active shelf content (HTML/XML family) to download; nosniff on
  artifact + content responses; unified unsandboxed-iframe PDF preview
  (fixes the pre-existing Chromium sandbox blank in the artifact viewer)
- scope document trash to the URL project under the document lock
- atomic no-overwrite filename reservation for ALL ingestion (seeded
  claims + os.link commit with suffix retry; same-name re-upload now
  unique-names instead of replacing); hidden staging only, no visible
  placeholders; lease cleanup on setup failure
- serialize conversion under the document lock with post-lock active
  revalidation; drain locked filesystem work on cancellation; preserve
  bytes when an insert's commit state is uncertain (including trashed
  rows)
- original-integrity checks before serving text or cached conversions;
  content_missing surfaced in list responses (UI reads the flag, no
  409-probe); downloads always serve original bytes
- bounded streaming document reads with cached char counts; shelf limits
  declared in middleware release identity
- thread-root confinement for from-thread sources; config fallback
  rejects fractional/infinite values; composer counts staged
  attachments; pending attachments persist until submission or removal;
  in-flight instruction/rename edits survive save refetches; shelf and
  trash pagination; conversation-file and thread-files pages stay
  subscribed to refetches

Docs: README/README_zh, backend API.md/ARCHITECTURE.md, AGENTS.md
contracts, config.example.yaml projects block.

Review follow-ups (head b4807477 → this revision):
- The trash retention sweep is split so repeated lazy triggers stay
  bounded: the indexed expiry purge still runs on every trigger
  (GET /api/trash/documents, POST /api/trash/purge) while the
  O(all rows + all files) reconciliation is throttled to one run per
  user per 15 minutes (process-local, per-user window). The startup
  sweep now runs as a background task instead of blocking gateway
  readiness, and shutdown awaits it (bounded).
- The export scrub (stripInternalMarkers) is fence- and indentation-aware
  like the render path, so a pasted, fenced <project>/<documents> snippet
  survives markdown export while real injected blocks (never fenced) are
  still removed. Fence regexes moved to a dependency-free leaf module to
  avoid the messages↔streamdown import cycle.
- The artifact viewer's PDF iframe no longer carries an added title
  attribute (the upstream e2e contract locates it via :not([title])), and
  the upstream artifact-preview spec now pins the new contract: PDFs
  render unsandboxed, images keep sandbox="".

* fix(projects): round-2 review — cancel an overrun trash sweep, restore the PDF frame title

- Shutdown cancelled only the shield around the background startup sweep,
  so an all-users reconciliation that outlived the 5s budget kept walking
  rows and files while the document repo and DB engine were disposed
  underneath it. The wait now lives in `_shutdown_startup_trash_sweep`,
  which cancels the task and drains it before worker exit: the shield
  keeps the wait bounded, the cancel makes it final (CancelledError lands
  at the sweep's next await, and `_run_startup_trash_sweep` only catches
  `Exception`, so nothing swallows it).
- The browser-preview iframe lost `title={getFileName(filepath)}` in the
  previous fix round, leaving the PDF frame without an accessible name
  while its siblings keep theirs. Restore it (WCAG frame titles), assert
  it in the DOM test, and anchor the e2e on `iframe[title="report.pdf"]`
  instead of `iframe:not([title])`.

* fix(projects): round-3 review — report the sweep's late finish, not a phantom cancel

`Task.cancel()` returns False when the sweep already finished inside the
window between the deadline firing and the cancel, so the shutdown log
claimed a cancellation that never happened. Branch on that outcome: the
warning stays for a real cancel, a late finish is logged at info, and both
paths still reap the task before worker exit.

* fix(projects): round-4 review — make Empty trash delete what it confirms

`POST /api/trash/purge` only ran the retention sweep, and the sweep's
candidate selection is age-gated, so a freshly trashed document survived
"Empty trash" even though the confirmation promises that every listed
document is permanently deleted. With one trashed row the route answered
`{"purged": 0}` and left it in place; `GET /api/trash/documents` sweeps
expired rows before listing, so the visible rows were normally ineligible
for the action by construction.

Empty trash now drives `purge_all_trashed`: the caller's trashed rows
(`list_all_trashed`, no age filter) each go through the same guarded,
row-locked `purge` as the single-document delete — bytes first, then the
row, in one transaction — so a row restored mid-flight is skipped instead of
force-deleted, and an unlink failure rolls that row back and answers 500 with
a retryable message. Retention expiry stays where it was: the sweep's
`purge_candidates` is now the only age-gated selection, and the lazy
retention sweep still runs on the listing and at startup.

Tests: the router suite replaces the retention-gated expectation with the
reviewer's repro (fresh row purged, bytes unlinked, shelf and other users'
trash untouched, a failing unlink stays retryable and 500); a blocking-I/O
anchor drives the new entry point through the offload; the mocked e2e covers
the action end to end; a new real-backend spec performs it against the real
gateway and re-reads `GET /api/trash/documents`. README, API, ARCHITECTURE
and the phase-2 design docs (en+zh) state the age-independent contract.

feat(gateway): accept conversation references in run context and report the capability (#5463)
* feat(gateway): accept conversation references in run context and report the capability

LangGraph SDK clients build a fixed run body and drop unknown top-level
fields, so they cannot send the conversation_references field from #5399.
RunCreateRequest now lifts context.conversation_references into the
top-level field before validation, so it keeps the same bounds and error
locations, and drops it from context, so it never reaches the merged run
context or the checkpointed configurable. Sending both is a 422.

GET /api/features reports conversation_references {enabled, max_references}
with the same "tool is configured" predicate as run admission, so a client
can hide an entry point on deployments without the tool.

Related to #5398.

* fix(gateway): report the field type error for a malformed top-level reference list

A malformed top-level conversation_references sent alongside a context
list now fails with the field's own type error instead of the conflict
message. The tool-configured predicate reads tool.use directly, and the
features test doubles carry that attribute like every real ToolConfig.

* fix(gateway): treat every list-like top-level reference value as a conflict

Pydantic's lax mode coerces tuples, sets, frozensets and deques into the
list[str] field, so a direct Python caller passing one of those together
with context.conversation_references now reports the conflict instead of
slipping both grants through. Unreachable over HTTP, where JSON has no
such types.

* fix(gateway): ask pydantic whether a top-level reference value is list-like

Enumerating list-like types cannot track pydantic's lax acceptance set
(generators, UserList, dict key views also coerce into list[str]). The
conflict guard now validates the top-level value with a TypeAdapter for
list[Any]: whatever pydantic would coerce reports the conflict when it is
non-empty, and whatever it rejects still surfaces the field's own type
error. Regression tests cover deque, UserList, dict keys and a generator,
plus rejected scalars.

* fix(gateway): probe top-level references with the field's own annotation

The conflict guard now validates the top-level value with the exact item
annotation the field uses, so its acceptance set is the field's rather than
a superset: an item the field rejects (an empty string, a non-string, the
ints of a range or dict view) surfaces the field's own item error instead
of a conflict. The annotation is shared through one alias so the two cannot
drift.

* fix(gateway): materialise a one-shot iterator before probing top-level references

The item-validating probe could consume a generator while collecting an
item error, after which the field re-validated the exhausted iterator,
coerced it to [] and let the request through with the key still in
context. Iterators are now read once into a list that both the probe and
the field validate, so a bad item is reported at its index and a valid
generator is kept.

* fix(gateway): materialise every once-walkable iterable before probing references

Pydantic coerces any iterable into the list field, and an object whose
__iter__ hands out a generator once is not an Iterator instance, so the
previous gate let it reach the probe and be consumed. The lift now reads
every iterable except lists, tuples and the shapes the field rejects as a
whole (str, bytes, dict) into a list first, so the probe and the field
always validate the same items.

fix(goal): stand the goal down once the run has hit its token budget (#5424)
* fix(goal): stand the goal down once the run has hit its token budget

Since #5410 goal continuations share the run's token budget, so a
continuation queued after the budget's hard stop only spends one more
model call before its tool calls are stripped. Pass the run's stop_reason
into the goal loop and stand the goal down with "token_capped" in that
case. The evaluator still runs first, so a goal the capped run satisfied
is cleared as before.

* docs(goal): list the token-budget stop among goal-loop preconditions

Also pin that a satisfied goal is cleared, not stood down, when the run
hit its token budget.

fix(gateway): serve XML artifacts as attachments to block same-origin script (#5353)
* fix(gateway): serve XML artifacts as attachments to block same-origin script

GET /api/threads/{id}/artifacts/{path} forced only text/html,
application/xhtml+xml and image/svg+xml to download. Every other XML
document was served inline from the application origin: `.xml` guesses
to text/xml or application/xml depending on the host's mime.types, and
both fell through to the inline text branches. Browsers render any XML
MIME type as a document and run an XHTML-namespaced <script> inside it,
so a report.xml written by a prompt-injected agent and opened from a
chat link executed with the viewer's session: the HttpOnly access_token
rides same-origin fetches, and the double-submit csrf_token cookie is
JS-readable, so state-changing calls are reachable as well.

Treat HTML plus every WHATWG XML MIME type (text/xml, application/xml,
any +xml subtype) and text/xsl, which Blink also renders as XML, as
active content. A single helper owns the rule for both the regular-file
and the .skill-archive-member branches. The artifacts panel already
previews .xml as code through a ranged fetch, so preview and editing
keep working against the attachment response.

* docs(frontend): name XML among the artifacts the Gateway downloads

Review follow-up on #5353: resolveArtifactOpenURL's comment still named
only HTML/SVG as the active content the Gateway serves as a download.
XML documents now join that bucket, so the frontend note matches the
Gateway rule. Comment-only; no behavior change.

fix(gateway): confine artifact PUT to /mnt/user-data/outputs after path resolution (#5321)
* fix(gateway): confine artifact PUT to /mnt/user-data/outputs after path resolution

The outputs-only guard on PUT /api/threads/{id}/artifacts/{path} was a
string-prefix check on the raw path. A percent-encoded `..`
(`outputs/%2e%2e/uploads/x.txt`) survives nginx's variable proxy_pass
untouched, is decoded by Starlette, passes the prefix check, and the
resolver only confines the result to `user-data/` -- so an owner could
overwrite a sibling upload or workspace file in their own thread.

Collapse dot segments before the prefix check, and re-check the resolved
host path against the resolved outputs root so a symlink planted inside
`outputs/` cannot redirect the write either. The normalized virtual path
is what the response echoes and what non-mounted sandboxes receive.

* refactor(gateway): share the outputs-confinement rule with channel attachments

Review follow-up on #5321: the "only under /mnt/user-data/outputs" rule was
implemented independently by the artifact editor and by IM-channel
attachment delivery, and the two copies had already drifted.

Move it into app/gateway/path_utils.py as normalize_outputs_virtual_path
(collapse `..` before the prefix check) and resolve_outputs_confined_path
(re-check the resolved host path against the resolved outputs root, which
also catches a symlink planted inside outputs/). PUT /artifacts and
ChannelManager._resolve_attachments both call the helper; artifact_archive
keeps its stricter ZIP-member rules layered on top.

Tests that previously stubbed resolve_thread_virtual_path for the editor now
stub resolve_outputs_confined_path, and the channel attachment tests patch
path_utils.get_paths, which the helper binds at import like the other
consumers. The confinement itself is pinned by tests/test_gateway_path_utils.py.

feat(gateway): paginate thread run history (#5283)
* feat(gateway): paginate thread run history (#5282)

GET /api/threads/{thread_id}/runs stays a bare array of the newest 100
runs so LangGraph SDK clients keep working. Add GET /runs/page with a
(created_at, run_id) keyset cursor so callers can walk older history.

* fix(gateway): reject one-sided run history cursors

RunManager.list_by_thread now raises if only one of before_created_at
or before_run_id is set, matching the HTTP 422. Document the per-page
sort cost on the SQL keyset query, and add the missing CHANGELOG
[#5282] link definition.

* fix(gateway): round-trip run page cursors through query strings

Emit next_before_created_at with a Z suffix so '+' is not decoded as a
space. Accept that space, and Z, when parsing. Treat blank cursor
fields as absent and reject a non-ISO before_created_at in RunManager
so a harness caller cannot silently restart at the newest page.

* style(gateway): ruff-format run page cursor files

Collapse the one-sided cursor ValueError and the two before_created_at
asserts so ruff format --check passes at line-length 240.

feat(projects): project workspaces with scoped chats and thread membership (#5265)
* feat(projects): project workspaces with scoped chats and thread membership

Backend:
- projects table model and migration; fail-closed ProjectRepository with
  ownership checks, CRUD/archive/restore/delete router, and atomic thread
  move between projects
- threads_meta.project_id column exposed as reserved deerflow_project_id
  metadata; project-aware thread create/search with pagination bounds and
  membership echoed in create responses
- first-run admission assigns the project only at genuine first run, seeded
  at write time and dropped when invalid; serialized against project
  deletion and thread assignment
- branch creation inherits the source thread's project membership (an
  archived/deleted project degrades the branch to unassigned instead of
  failing the request)

Frontend:
- projects data layer, thread move API, and sidebar projects section with
  flat/grouped modes, archived-project threads, and stable virtual-list
  offsets
- project detail page with project-scoped new chat
  (/workspace/chats/new?project=) and paginated thread list
- move-to-project thread menu, new-project dialog, archived-project gates
- project-scoped new chats pre-create the thread with membership before the
  first submit or /goal set, so runs never proceed outside the project
- goal-set preparation is fenced against conversation switches: a stale
  continuation is dropped instead of saving the goal or launching the
  abandoned submission on the newly opened conversation
- project thread lists join thread lifecycle invalidations (stop, pin) so
  an open project page never keeps stale titles, recency, or pagination

* fix(chats): keep archive undo toast when the sidebar row unmounts

The archive success toast was fired from per-mutate callbacks passed to
mutation.mutate. React Query drops those handlers when the observer
component unmounts before the mutation settles; archiving the open chat
removes its sidebar row mid-flight, so the undo toast never appeared and
the e2e archive-undo test timed out waiting for it.

Move the success/error handlers to the mutation level (useArchiveThread
options, same pattern as useMoveThreadToProject) where callbacks are
delivered even after the originating row unmounts.

* fix(projects): pin project thread listing contract and exclude archived chats

GET /api/projects/{id}/threads returned the thread store row verbatim
(list[dict], no response_model): user_id/assistant_id leaked, any future
ThreadMetaRow column would auto-leak, and the OpenAPI schema was empty.
Return a narrow ProjectThreadResponse (the exact fields ProjectThread
declares) with the same metadata secret redaction the surrounding thread
endpoints get from _MetadataRedactingResponse.

The listing also ran search() without the archived filter, so a retired
chat rendered as a normal row on the project page while the sidebar hid
it. Search archived=False to mirror the sidebar's archived:false lists;
restore stays on the global Archived tab.

Both regressions pinned by new router tests: wire-shape allowlist and
archived-member exclusion.

* docs(migrations): record the 0019/0020 chain against the bootstrap reservation

The tree now chains 0018 -> 0019_projects -> 0020_threads_meta_project_id,
so migrations/AGENTS.md was stale twice over: the revision index stopped at
0018 and the rolling-forward section still claimed the tree 'deliberately
remains at 0018'.

Document the new head and record the intentional numeric-prefix reuse of
0019: 0019_projects is in-chain while 0019_thread_incarnations stays the
reserved, allowlisted out-of-tree rollout id. The owning rollout revision
must re-parent onto this tree's head when it merges so alembic never sees
two heads off 0018; bootstrap.py now cross-references that note next to
_FORWARD_COMPATIBLE_REVISION.

* fix(chats): invalidate project thread lists on archive/restore

useArchiveThread refreshed the infinite sidebar cache, threads/search and
the per-thread metadata cache but not the project-scoped list
([...PROJECTS_QUERY_KEY, 'threads', id]) this PR adds — the one thread
mutation not wired to that key, after usePinThread, useRenameThread,
useDeleteThread, useMoveThreadToProject and invalidateStoppedThreadCaches.

An archive from a sidebar row while a project page is open therefore left
the archived chat rendered as a normal row until remount (and undo left it
missing). Invalidate the prefix in the mutation-level success handler.

Regression test asserts the project-list prefix is invalidated on success.

* fix(projects): fetch project discovery only in grouped sidebar mode

RecentChatList mounted two useProjects queries per sidebar render, but
knownProjectIds is consumed only by the grouped-mode exclusion filter; in
the default flat mode every page load paid two GET /api/projects?status=
round trips for data nothing read. Gate both queries on grouped mode —
GroupedProjectList fetches the same keys when the toggle is on and
TanStack dedupes the observers.

Also set retry: false on useProject: a deleted or foreign project 404s
deterministically, and the page renders a dedicated not-found state for
it, so the default 1s/2s/4s retry backoff kept deep links in 'loading'
for ~7s before that state appeared. Matches useThreadMetadata /
useThreadTokenUsage.

* fix(threads): fail closed on project-scoped create in memory mode

MemoryThreadMetaStore.create accepted project_id and silently ignored it,
making memory mode the one membership path that fails open: POST
/api/threads with a project id returned 200 and the run started
unassigned, violating the invariant that a run never proceeds outside the
selected project (the SQL store raises ProjectNotAssignableError inside
the insert transaction for the same request).

Raise ProjectNotAssignableError whenever project_id is present so the
router's existing 404 mapping applies, the frontend keeps the composer
text for a retry, and memory mode behaves exactly like SQL mode.
set_project already reports rejection; create now matches it.

Store-level test (raises, nothing persisted, project filter stays empty,
unscoped creates still work) plus a router-level test asserting the 404
and that no row is left behind.

* fix(projects): window the project page thread list

ProjectThreadsSection rendered every loaded page as a plain Link row, so a
long-lived project accumulated unbounded DOM on the page's scroll surface:
each load-more appended another 100 rows and every formatTimeAgo tick
re-rendered the whole list.

Reuse VirtualThreadList (now generic over any row shape with a
thread_id), pointing its scroll parent at this page's ScrollArea viewport
via the shared [data-slot="scroll-area-viewport"] selector used by
/workspace/chats; under the 60-row threshold it falls back to the plain
render, so small projects are unchanged.

* fix(projects): restore row dividers and pin them with a render test

The row class template literal concatenated transition-colors directly
with the conditional border-b token, so non-final rows rendered the
invalid class 'transition-colorsborder-b' and lost both the divider and
the transition. Compose the row classes with cn() and a boolean guard
instead.

The section moved out of page.tsx into a testable component so the row
markup finally has coverage: a DOM test asserts every row except the
final data row carries border-b (index-based, not last: — correct under
virtualization where the last mounted row is not the last data row), and
the untitled fallback plus load-more button render for a partial page.

feat(gateway): support idempotent thread runs (#5258)
* feat(gateway): support idempotent thread runs

Accept Idempotency-Key on thread-scoped create, stream, and wait endpoints, scoped by owner and thread before durable admission.\n\nRefs #5257.

* fix(gateway): handle idempotent run reuse on wait and stream

Reused store-only records have no local task. /wait now waits on the
bridge when it can observe the stream, and otherwise returns durable
status instead of a stale checkpoint. A reused terminal stream that has
been evicted emits gap/reload_durable_state. Replay is bound to the
original input and assistant_id.

* fix(gateway): 409 reused in-flight streams on this worker

A store-only running record on a process-local bridge has no owner
stream. POST /runs/stream used to subscribe anyway, which created an
empty log and waited forever. Match join: 409 unless the run is already
terminal, so missing-stream retries can still emit gap.

* fix(gateway): keep observer joins off the idempotent stream-gap path

sse_consumer keyed missing-stream gap on the sticky
idempotency_reused flag, so a later join of a terminal run inherited
it. Gate that branch on apply_on_disconnect, which already separates
creating streams from joins. Document the retry outcomes clients have
to handle.

* fix(gateway): gate missing-stream gap on creating retry

Reuse apply_on_disconnect to pick gap vs end changed sse_consumer default path, so a missing stream started returning gap for default callers and for out-of-scope POST /api/runs/stream. Keep that branch behind emit_gap_on_missing_stream and pass it only from thread-scoped /runs/stream on this request reuse.

* fix(gateway): keep wait reuse off later checkpoints

Direct handler calls were crashing because FastAPI Header() leaked in as the Python default. Bind Idempotency-Key with Annotated so the default is None, and ignore non-str keys.

A reused completed /wait was still reading the latest thread checkpoint. After a later run on the same thread that is the later run's result. Return durable status instead of claiming the head as this run's output.

* fix(gateway): snapshot wait reuse and refresh store status

idempotency_reused lives on the shared cached record. Capture it before awaiting completion so an overlapping retry cannot suppress the original creating /wait checkpoint.

A store-only peer record still holds admission-time status after the owner publishes END. Refresh durable status/error before returning them.

feat(gateway): add /health/ready readiness probe backed by the database (#5166)
* feat(gateway): add /health/ready readiness probe backed by the database

## Why

GET /health only proves the process is up: it returns 200 even when the persistence engine cannot reach the database. Orchestrators already treat it as a readiness gate (docker-compose.yaml marks the gateway service healthy and nginx depends_on service_healthy), so a DB outage or a still-migrating Postgres leaves the stack 'healthy' while every request fails.

## What changed

- New GET /health/ready endpoint: bounded SELECT 1 against the existing persistence engine (deerflow.persistence.engine.get_engine) with a 2s timeout.

- Response is 200 {'status': 'ready', 'database': 'ok'} when reachable, 503 {'status': 'degraded', 'database': 'unreachable'} when the probe fails, and 200 ready with database=not_configured for backend=memory (nothing to probe).

- GET /health is unchanged (pure liveness), and /health/ready is public through the existing /health auth whitelist.

- docker-compose.yaml gateway healthcheck now polls /health/ready so service_healthy reflects database reachability.

- Documented both endpoints in backend/app/gateway/AGENTS.md.

## Surface area

- [x] Backend API - new GET /health/ready endpoint under backend/app/gateway

- [x] Sandbox / Docker - gateway healthcheck in docker/docker-compose.yaml now gates on readiness

- [ ] Frontend UI / Agents / Skills / Dependencies

- [x] Default behavior change - existing /health unchanged; the prod compose healthcheck is stricter (503 while the database is unreachable)

## Validation

- New unit tests in backend/tests/test_gateway_health.py cover ok / unreachable / not_configured probe results and the 200/503 payload mapping (6 passed).

- app.gateway.app imports cleanly and registers both /health and /health/ready.

- ruff check + ruff format clean.

* fix(helm): point the gateway readiness probe at /health/ready

## Why

Review on #5166 (willem-bd, P1): the chart still probed /health for readiness,
so Kubernetes marked the pod ready and routed traffic while the database was
unreachable - exactly the failure mode /health/ready was added to catch.

## What changed

- deploy/helm/deer-flow/templates/gateway-deployment.yaml: readinessProbe
  httpGet.path now hits /health/ready (DB-backed, 503 while the database is
  unreachable). The liveness probe stays on /health.

## Verification

- One-line path change inside the existing readinessProbe block; git diff
  confirms only the readiness path changed (liveness untouched).

* fix(gateway): readiness probe also checks the effective checkpointer/Store backend

## Why

Follow-up review on #5166 (willem-bd, P1): get_engine() only represents the
ORM backend selected by `database:`. The legacy `checkpointer:` section takes
precedence for the LangGraph checkpointer and Store, so a split configuration
(a local SQLite/memory `database:` with `checkpointer.type: postgres`) could
report 200 while the PostgreSQL backend agent runs depend on was down.

## What changed

- GET /health/ready now probes both persistence halves: the ORM engine behind
  `database:` (unchanged) and the effective LangGraph checkpointer/Store
  backend resolved with the runtime's own rule (legacy `checkpointer:` config,
  otherwise derived from `database:`), for memory/sqlite/postgres backends.

- The payload gains a `checkpointer` field with the same
  ok / not_configured / unreachable vocabulary as `database`; 503 degraded is
  returned when either probe is unreachable.

- Probes are bounded by the existing 2s timeout: sqlite via aiosqlite SELECT 1
  on the resolved path, postgres via a bounded psycopg AsyncConnection SELECT 1
  on the DSN with the configured search_path. A missing driver for a configured
  backend degrades readiness (the runtime could not run either).

- Documented the two-probe semantics in the endpoint docstring and
  backend/app/gateway/AGENTS.md.

## Verification

- New tests: healthy ORM engine + unreachable legacy checkpointer backend ->
  503 degraded with database: ok / checkpointer: unreachable; checkpointer
  probe mapping for memory/sqlite(postgres missing-driver) backends; existing
  payload tests now pin the checkpointer field.

- cd backend && python -m pytest tests/test_gateway_health.py: 11 passed.

- app.gateway.app imports cleanly; ruff check + ruff format clean.

* fix(gateway): bound /health/ready to one deadline and probe the startup checkpointer snapshot

## Why

Second round of review on #5166 (zhfeng P1/P2, willem-bd P1/P1/P2). Three
correctness issues remained in the readiness endpoint:

- The database and checkpointer probes ran sequentially, each allowed 2s, so a
  healthy response could take almost 4s - past Kubernetes' 1s default
  readinessProbe timeout and inside Docker's 3s client timeout. A slow but
  healthy backend could make every replica unready.

- The checkpointer probe re-resolved process-wide, hot-reloaded configuration
  per request, while app.state.checkpointer/store are built once from the
  startup_config snapshot in langgraph_runtime(). After a live config edit the
  endpoint could probe a backend the running gateway does not use, and a
  resolution failure was swallowed into None -> not_configured -> 200.

- The SQLite probe opened the path with aiosqlite.connect(), which creates the
  file when missing: a deleted checkpoint database was silently resurrected as
  an empty file and reported ok instead of surfacing the outage.

## What changed

- backend/app/gateway/health.py: the two probes now run concurrently beneath a
  single endpoint-wide deadline (_READINESS_DEADLINE_SECONDS=3.0) so a healthy
  response completes within one probe window (~2s), never the sum of both.
  A probe that overruns the deadline degrades the endpoint instead of hanging.

- langgraph_runtime() now records the checkpointer/Store config resolved from
  the same startup_config snapshot its checkpointer/store singletons are built
  from (app.state.checkpointer_config); /health/ready probes that snapshot and
  never re-resolves hot-reloaded config. resolve_checkpointer_config() returns
  None on resolution failure and the endpoint fails closed (503, checkpointer:
  unreachable) instead of reporting not_configured.

- The SQLite probe opens disk-backed paths with the non-creating mode=rw URI
  flag, so a missing database file stays missing and yields unreachable;
  in-memory forms (:memory:, file:...mode=memory) have nothing external to
  probe and report not_configured like the memory backend.

- Orchestrator timeouts now sit above the endpoint bound: Helm readinessProbe
  gains timeoutSeconds: 5 (Kubernetes default is 1s) and the docker-compose
  gateway healthcheck client timeout moves from 3s to 5s.

## Verification

- New regression tests: concurrent probes keep total elapsed time within one
  probe window; a probe ignoring its budget trips the endpoint deadline to 503;
  missing SQLite file stays absent and yields unreachable; in-memory SQLite
  forms map to not_configured; missing startup snapshot / config resolution
  failure fail closed to 503; resolve_checkpointer_config() raising is covered.

- cd backend && python -m pytest tests/test_gateway_health.py: 21 passed;
  tests/test_gateway_docs_toggle.py and lifespan/shutdown gateway suites pass.

- ruff check + ruff format clean on all changed files.

* fix(gateway): serialize connection-opening readiness probes behind a strict gate

## Why

Review on #5166 (willem-bd, P1): every request to /health/ready opened a new
PostgreSQL connection in _probe_postgres_backend, outside both the ORM pool and
the runtime checkpointer pool. The route is public through the /health auth
prefix and nginx proxies /health/*, so concurrent unauthenticated requests
could create an unbounded number of connections (each held for up to two
seconds), exhaust PostgreSQL max_connections, and take down both normal
traffic and the readiness probe itself.

## What changed

- backend/app/gateway/health.py: connection-opening checkpointer probes
  (sqlite connect, postgres AsyncConnection.connect) now run inside a strict
  per-process gate - an asyncio.Lock cached per running event loop - so at
  most one probe connection can be in flight per worker process. Requests
  that queue behind the gate are still shed by the existing endpoint-wide
  deadline, so a flood cannot pile up new connections or open files.

- Memory and unknown-backend decisions stay outside the gate; payload and
  probe semantics are unchanged. The serialization is documented in the
  module docstring and backend/app/gateway/AGENTS.md.

## Verification

- New regression test: 8 concurrent readiness_payload() requests against an
  instrumented sqlite probe assert the maximum number of in-flight probe
  connections is 1 while every request still returns 200.

- cd backend && python -m pytest tests/test_gateway_health.py: 22 passed;
  tests/test_gateway_docs_toggle.py and tests/test_gateway_lifespan_shutdown.py
  also pass on the merged main head.

- ruff check + ruff format clean on all changed files.

(#4666, #4508, #4363). Both are reproduced by a real two-round run: once the
thread passes the 50-row `/messages/page` window AND context compaction fires,
the two sources of truth stop overlapping at the head.

1. Middleware-answered tool results never reached the event store. A middleware
   that short-circuits a tool call (e.g. ReadBeforeWriteMiddleware's blocked
   write) returns a user-visible ToolMessage, but LangChain never emits
   `on_tool_end`, so RunJournal never persisted it — the user saw it during the
   run and it vanished on reload. RunJournal already reconciles final-output
   tool messages, but only for an `ask_clarification` allowlist. The allowlist
   is removed; scope stays bounded by the three conditions that actually matter
   (visible, this run's lead agent, not already persisted), so subagent results
   still stay in their own step feed.

2. mergeMessages discarded the checkpoint prefix before the first shared anchor.
   #4065 correctly established that a summarization-rescued early message must
   not be appended to the tail, and suppressed it instead. That suppression is
   what deletes the message when the first history page no longer reaches back
   to it. It is now woven in before the first shared anchor — the one position
   both the checkpoint and seq-sorted history agree on — so #4065's invariant
   (never the tail) still holds. A collapsed unloaded gap is recoverable by
   paging; a dropped message is not.

Verified against real captured payloads from the reproducing run: the first user
message returns to the transcript. Its exact position is still approximate —
after compaction the live window carries too few anchors to place it precisely,
which only seq-based ordering can close.

Backend: 10809 passed (baseline 10808; same 15 pre-existing failures in
browser/crawler community tools). Frontend: 986 passed, typecheck + eslint clean.

* feat(events): look up a persisted message's seq by identity

Groundwork for placing checkpoint messages in the seq-ordered thread feed
(#4666). A checkpoint carries no seq of its own and loses messages to
summarization, so once the feed's 50-row page window no longer reaches back to a
surviving old message, a client has nothing to place it by. The seq already
exists in run_events keyed by the message id — this exposes it without paging
the whole feed.

`message_identity` is the backend half of the identity rule the frontend applies
in `hooks.ts::messageIdentity`: a ToolMessage is keyed by `tool_call_id`, and
DynamicContextMiddleware's `X` / `X__user` human copies collapse to one identity.
The two halves must stay in sync — a mismatch is silent, degrading placement
rather than raising.

`get_message_seqs` is implemented for all three stores. Misses are absent from
the result rather than an error, so callers degrade to their own placement rule;
the earliest seq wins when one identity resolves to several rows, so a
re-persisted message keeps the position it first occupied. The DB store decodes
rows in Python because `content` is a TEXT column holding a JSON string, not a
JSON column — the identity fields cannot be projected in SQL.

Nothing consumes this yet; no behavior change.

* feat(runtime): carry each persisted message's feed seq on values frames

Attaches `additional_kwargs.deerflow_seq` to messages in a root `values` frame
that the thread feed already holds, so a client can place a message the
checkpoint kept but its loaded history page window no longer reaches (#4666).
Nothing is written back to the checkpoint: the seq is added when the frame is
serialized and belongs to that frame only.

Cost is bounded to frames introducing identities the run has not resolved yet.
Messages this run produces are not in the feed while streaming, so they are
looked up once, recorded as misses, and never retried — in a real run the only
frame that pays for a query is the one where compaction brings older messages
back into view. Measured on a reproducing two-round run: 1 lookup across 25
values frames.

The stamper is built once per run rather than per `_stream_once`, or a goal
continuation would discard the resolved seqs. Subgraph frames are not stamped:
a subagent's snapshot is not part of this thread's feed ordering. A lookup
failure logs and leaves the frame unstamped rather than failing it — placement
is an enhancement and clients fall back to their own ordering rule.

Frontend does not read the field yet; no behavior change.

* fix(gateway): strip the server-owned message seq from untrusted input

`deerflow_seq` is display metadata the Gateway attaches when it serializes a
values frame. A client replaying messages (regenerate / edit-and-rerun) would
otherwise write it into the checkpoint, where it becomes wrong the moment the
thread is forked — a branch re-seeds its feed and reassigns seq (#4380).

Joins the existing server-owned key set, so it follows the same trusted-internal
rule as the dynamic-context and view-image markers.

* fix(frontend): place a checkpoint message by its feed seq, not its nearest anchor

Completes #4666. Weaving a compaction-rescued message before the first shared
anchor keeps it in the transcript, but not in the right place: after compaction
the live window carries too few anchors, and the nearest one can sit deep inside
the loaded page window — measured at row 25 of 50 on a reproducing run, which is
why the first user turn rendered mid-transcript instead of at the head.

Both sides now carry the backend's thread-global seq. `buildVisibleHistoryMessages`
copies each row's `seq` onto the message (same shape as the existing `run_id`),
and the Gateway stamps it onto `values` frame messages it has already persisted.
A live message whose seq is below the loaded window's lower bound is placed ahead
of everything on screen rather than before the nearest anchor. A message with no
seq — still streaming, so not in the feed yet — keeps the weaving path, since the
tail is already its correct position.

Verified against the captured payloads of the reproducing run: the first user
message goes from absent, to #13 (behind the second question), to #0.

Frontend: 988 passed, typecheck + eslint clean.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(frontend): place a pre-window checkpoint message even when no anchor is shared

Also #4666. Placing a compaction-rescued message by its feed seq was gated on
reaching a shared anchor, because the split ran inside the anchor walk. When the
loaded page and the live checkpoint share no identity at all, that walk never
runs and the message fell through to `[...canonical, ...live]` — appended after
the entire window, the one arrangement #4065 proved wrong, with its seq known
the whole time.

That is not a corner case. Open an old, already-summarized conversation and send
a message: the page on screen is the newest rows from before that turn, while
the checkpoint holds the rescued first user turn plus steps of the new run that
are not in the feed yet. On a reproducing run the two sides shared zero anchors
and the user's own first question rendered at row 50 of 50 — the reported
"first message jumps to the bottom".

Split `beforeWindow` out of `live` before walking anchors, walk `liveInWindow`,
and use it for the no-anchor branch as well, so a message routed ahead of the
window is not re-appended at the tail by dedup.

Measured on captured payloads of a reproducing run (real gateway, real
compaction), first user message position:

  no shared anchor:  row 50 -> row 0, seq order monotonic again
  shared anchors:    row 0 -> row 0 (unchanged)
  paged to the top:  row 0 -> row 0 (unchanged)

Regression test verified red-green: reverting the fix fails it with the message
rendered after the window.

Frontend: 989 passed, eslint + tsc clean.

* fix(gateway): stamp the message feed seq on checkpoint reads, not only on stream frames

Completes #4666. `_MessageSeqStamper` sits on the streaming publish path, so a
client that joins a live run learns where a summarization-rescued turn belongs
while a client that merely opens the conversation does not — and opening is the
common case. `GET /threads/{id}/state` and `POST /threads/{id}/history` returned
the checkpoint with no seq at all, so the merge fell back to the nearest shared
anchor, which after summarization sits deep inside the loaded page.

Reproduced in a browser against a real gateway, on a thread that had already
compacted: the user's first question rendered at row 320 of 389, behind the
newest question instead of at the head. Both reads showed 0 of 13 messages
carrying a seq. That is the reported symptom, still present after the streaming
fix.

Add `stamp_messages_with_seq`, the request-scoped counterpart of the stamper:
everything a checkpoint still holds is already persisted, so one batched lookup
resolves the whole list and there is nothing to retry later. Resolve the store
through `_optional_run_event_store` rather than `get_run_event_store`, because
seq is placement metadata — a deployment without a feed must still be able to
read a thread.

After the fix, on the same thread in the same browser: 13 of 13 messages carry a
seq and the first question renders at the head, ahead of the newest one.

Backend: ruff clean, 326 passed across the touched suites.

* refactor(harness): move the injected-user-id suffix helpers to utils.messages to break an import cycle

message_identity imported strip_injected_user_message_id_suffix from the
dynamic-context middleware, closing a cycle (middleware -> deerflow.runtime
-> worker -> events -> middleware) that only stayed hidden while an earlier
import happened to break it. Define INJECTED_USER_MESSAGE_ID_SUFFIX and the
strip helper in deerflow.utils.messages and re-export them from the
middleware so existing importers keep working.

* fix(docs): improve formatting and clarity in AGENTS.md and message-merge.test.ts

* perf(events): stop the seq scan once every wanted identity is resolved

Rows past the last wanted seq can only be re-persisted copies that
already lose the earliest-seq-wins tiebreak, so all three stores now
break out of the scan (and the db store out of its per-row JSON
decoding) once found covers wanted. Matters most for /state and
/history reads of long threads, where this lookup runs with no run
cache and a typically tiny wanted set.

Raised by review on #4696.

* refactor(events): share the seq-stamping expression between the two stampers

The walrus-plus-merge expression was duplicated verbatim between
stamp_messages_with_seq and _MessageSeqStamper.stamp — two counterparts
of one rule where silent divergence is the likely failure mode if only
one side is edited. Both now call attach_message_seq next to
MESSAGE_SEQ_KEY in message_identity.py. The trailing
isinstance(message, Mapping) guard was unreachable (a non-Mapping entry
already got identity = None) and is gone with the extraction.

Raised by review on #4696.

* fix(events): seq stamping survives launch paths without user context

The db store's get_message_seqs defaults to user_id=AUTO, which raises
when no user is in the contextvar — the first strict-AUTO read ever
called from the worker context. On a launch path that never inherits
the auth context (e.g. a null-owner scheduled task), stamp()'s except
clause swallowed that into a per-frame warning and silently disabled
seq stamping for exactly the background runs that need it.

The stamper now soft-resolves the user id once at build time — the
same rule as the worker's write paths beside it (unset -> no filter)
— and passes it explicitly. jsonl/memory stores gain the same
user_id kwarg the base list_messages contract already carries.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* perf(events): SQL-prefilter the message seq lookup's candidate rows

get_message_seqs scanned and JSON-decoded every message row of the
thread: the early exit never fires when a wanted identity is absent
from the feed (a message still streaming, or checkpoint-only), and
/state / /history reads want the newest messages, so the ascending
scan traversed essentially the whole feed — with the content column
carrying full tool outputs, that is heavy I/O plus N JSON parses on
exactly the long threads this lookup exists for.

A LIKE prefilter now keeps that cost in SQL: only rows containing a
wanted raw id as a substring are fetched and decoded. False positives
are re-checked by message_identity; LIKE wildcards are escaped; an id
json.dumps would escape (breaking the verbatim-substring guarantee)
falls the whole set back to the full scan rather than silently
missing.

* docs(agents): sink runtime mechanism docs below the gateway guidance budget

Merging main pushed backend/app/gateway/AGENTS.md past its 40KB soft
budget (main had left 81 bytes of headroom). Per the nearest-file rule,
move the mechanism detail of the message-seq stamping and run-delivery
receipt sections — both owned by runtime/ code — into
packages/harness/deerflow/runtime/AGENTS.md, leaving the gateway file
the REST-surface summary and a pointer. The seq section also documents
the stamper's build-time soft user-id resolution and the db store's SQL
prefilter from the review follow-ups.

* docs(agents): sink durable-MCP task detail below the backend guidance budget

Merging main pushed backend/AGENTS.md past its 24KB module soft budget
(main itself is at 24762 after #4848 — this branch adds zero net bytes
to the file). Per the nearest-file rule, move the two durable-MCP task
runtime bullets' mechanism detail into
packages/harness/deerflow/mcp/AGENTS.md, leaving summaries and
pointers; this also restores ~2KB of headroom so the next merge does
not trip the same wire.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(events): re-ask a message-seq miss once the feed advances

The run-scoped stamper cached lookup misses for the whole run. A message
this run produces reaches a values frame before RunJournal flushes it, so
its first lookup legitimately misses — and the journal persists it moments
later, giving it a feed seq the stamper never asks for again. A long run
that afterwards rolls past the history page and compacts then carries that
message unstamped, back to the approximate anchor placement this stamper
exists to replace (#4666). A transient store error had the same permanent
effect, since the except clause degrades to an empty result.

A miss is now provisional while a hit stays final: RunJournal counts its
successful event-store writes as `feed_generation`, and the stamper re-asks
a missed identity only once that counter moves. Retrying is therefore
bounded by feed writes rather than by frames — the per-frame query the
run-scoped cache was built to avoid — and a failed lookup costs one
generation instead of the run.

feature(gateway): issue request trace ids unconditionally (#5119)
* refactor(gateway): issue request trace ids unconditionally

The request trace id was gated behind logging.enhance.enabled at every
entry point, so downstream code had to keep asking whether one existed:
a header-provenance flag in its own ContextVar, a precedence resolver,
and three-level carrier fallbacks at each consumer.

Bind one unconditionally instead. TraceMiddleware covers Gateway HTTP;
ensure_trace_context covers the entry points that never touch ASGI --
scheduled occurrences, MCP task notification runs, IM channel messages,
and the embedded client -- each scoped to one unit of work so a
long-lived worker task cannot leak one occurrence's id into the next.
The ContextVar becomes the only source; the response header, runtime
context, run metadata and log records are derived outputs.

Consumers now use ensure_trace_id() or resolve_trace_id(*carriers) and
drop their presence guards. Removed: resolve_deerflow_trace_id, the
header-provenance flag and its three helpers, set/reset_current_trace_id,
is_trace_correlation_enabled and its gateway alias.

BREAKING CHANGE: every Gateway HTTP response now carries X-Trace-Id and
it cannot be turned off; logging.enhance.enabled controls log output
only. Installations on the default enabled: false will start seeing the
header. No config keys were added or removed.

* fix(gateway): stop persisting a caller-supplied trace id on the run record

body.metadata forks two ways: through build_run_config into the live run
config, which the run worker restamps, and through create_or_reject into
the run record that the runs API echoes verbatim. Only the first was
covered, so a client sending metadata.deerflow_trace_id made the most
durable and most visible surface of a run disagree with the X-Trace-Id
and the log lines the same request produced -- a correlation id that
does not match the logs is worse than none.

Stamp the server-issued id once at the trust boundary so both forks
receive it, preserving the caller's own metadata keys. Close the same
gap on config.context, which reaches the runtime context by a separate
path: _build_runtime_context no longer merges server-owned keys from the
caller, and _install_runtime_context assigns rather than setdefaults.

A thread's metadata is no longer seeded with the run-scoped id of
whichever run created it -- one thread spans many runs and as many
trace ids.

Found by driving a real run through the Gateway and reading the run back
from the runs API; every unit test built its metadata by hand and so
could not see it.

* fix(gateway): expose X-Trace-Id to split-origin browser clients

X-Trace-Id is not on the CORS safelist, so a browser client served from
a separate origin could not read it -- and those are exactly the clients
that cannot read the Gateway's logs either, leaving them with nothing to
quote in a bug report. Same-origin nginx deployments were unaffected,
which is why this stayed hidden.

Add it to CORS_EXPOSED_HEADERS beside Content-Location, referencing
TRACE_ID_HEADER rather than repeating the literal.

* fix(gateway): keep X-Trace-Id on unhandled-exception 500s

Starlette's ServerErrorMiddleware sits outside every user middleware and
emits unhandled-exception 500s through the raw send, so those responses
never pass TraceMiddleware's header-writing wrapper. The 500 for a server
bug is exactly the response a user most needs to correlate with a log line,
and it was the one response that shipped without the id.

TraceMiddleware now tracks whether http.response.start has been sent. On an
exception with no response started it emits its own plain 500 carrying the
header, then re-raises: the outer ServerErrorMiddleware sees the response
already started and only re-raises too, so the server's exception logging is
untouched. An exception mid-stream keeps propagating unchanged — a second
response start cannot be sent, and the already-written header stands.

The trace id is printable ASCII by construction (normalize_trace_id /
generate_trace_id), which is what makes the raw latin-1 header encoding
safe.

* fix(gateway): strip the forged trace id from the persisted request echo

The run-record fix stopped a forged metadata.deerflow_trace_id on the
authoritative metadata surface, but the raw request echo still carried one:
create_or_reject persists body.config verbatim as runs.kwargs_json, which
the runs API serves back. A client posting config.context.deerflow_trace_id
therefore still got its forged value stored and echoed on one API surface
while the header, logs, run metadata, and checkpoint all carried the real
id — the id is ignored as input there, so echoing it back only manufactures
disagreement.

Two changes close it. redact_config_secrets — already the shared scrub for
that echo, applied at admission and again at serve time, so historical
records are covered too — now also drops deerflow_trace_id from
config.metadata and config.context. And build_run_config now merges run
metadata onto a copy of the caller's config["metadata"] instead of updating
it in place: the nested values of the request config are reference copies,
so the in-place merge was writing the server-stamped key through into
body.config, contaminating the "what the client sent" record before it was
persisted (and incidentally masking the forged-value echo on the metadata
container).

The regression test posts a forged id through body.metadata,
config.metadata, and config.context at once and reads the kwargs echo back
off the run record, failing if either leak returns.

* docs(harness): record the trace-echo scrub, 500 fallback, and accepted retry divergence

The trace section of the harness AGENTS.md now covers the two fixes that
close the derived-output rule (the kwargs-echo scrub in
redact_config_secrets plus build_run_config's copy merge, and
TraceMiddleware's own 500 for unhandled exceptions), and CHANGELOG gains
their Fixed entries.

It also writes down the one accepted divergence: a crash-recovered
scheduled launch reuses the durable run through its idempotency key, and
start_run returns early on idempotency_reused without restamping — so the
run record keeps the first attempt's deerflow_trace_id while the retry's
own log lines carry the freshly minted id of its ensure_trace_context
binding. The divergence is confined to the crash-recovery window and is
accepted rather than fixed: restamping on reuse would rewrite a persisted
record for a run that already exists, which is worse than two ids that each
correlate their own attempt's logs. Written down so the next reader of the
scheduler recovery path does not diagnose it as a bug.

* docs(config): align the logging.enhance schema note with the unconditional trace id

The config-module AGENTS.md still described logging.enhance as the gate for
the Gateway X-Trace-Id header and Langfuse deerflow_trace_id. That model is
gone: ids are issued unconditionally and this block decides log output only.
Left as-is, the stale wording invites an agent to "restore" a header gate it
believes was lost. Reworded to match the sibling AGENTS.md files and
config.example.yaml, with a pointer to the Request Trace Context section
that owns the full model.

* docs(changelog): link the trace entries to #5119

The five new entries pointed at the ([#XXXX]) placeholder with no reference
definition, rendering as literal text instead of a link — and RELEASING.md
step 2 relies on those references when the section becomes release notes.
All five now point at #5119, with the definition appended to the reference
block.

* refactor(harness): rename _stream_without_trace_context to _stream_turn

The name asserted the opposite of what the method now does. It was accurate
while logging.enhance.enabled could route stream() around the trace scope;
with the gate gone it is the only stream implementation left, and it binds
the id itself via ensure_trace_id(). Private, so the rename touches only the
definition and the one stream() call site.

* docs(harness): fit the trace-context guidance inside the AGENTS.md chain budget

The expanded Request Trace Context section pushed the effective AGENTS.md
chain for agents/middlewares to 99,815 bytes, past the 98,304 hard limit
scripts/check_agent_guidance.py enforces in CI (AG002). Compressed the
section from 7,359 to 4592 bytes with no facts removed: the entry-point
table, the derived-output rule and its enforcement points, the accepted
scheduled-retry divergence, the two resolution helpers, the stream()
binding rationale, the log-output-only gate, the CORS listing, the 500
fallback, and the test map all remain.

Sized against the merge, not just the branch: current main grew the same
chain by ~724 bytes, so the check was verified on the merged tree as well
(97,772 bytes; branch tree 97,048).

* fix(gateway): declare content-length on the fallback 500

The pre-response 500 declared content-type but no content-length, leaving
the framing to the ASGI server: chunked on HTTP/1.1, close-delimited on
HTTP/1.0 — the one wire difference from the ServerErrorMiddleware response
it replaces, which sends content-length: 21. The explicit header keeps the
fallback byte-identical to what clients saw before.

* docs(readme): drop the trace-correlation condition from the translations

The zh/ja/fr/ru Langfuse sections still said metadata.deerflow_trace_id
matches X-Trace-Id "when request trace correlation is enabled". The id now
always matches and that condition no longer exists, so each bullet states
the unconditional match and that logging.enhance.enabled only controls
whether the id is printed into logs — the one piece of the feature a user
can still configure.

* test(gateway): pin TraceMiddleware wiring through create_app()

Every X-Trace-Id test exercised a hand-built four-route app, so the real
stack's add_middleware(TraceMiddleware) line was pinned by nothing: deleting
it — or short-circuiting above it — passed CI while silently dropping both
the response header and the ambient id the run-record stamp and enhanced log
records derive from. One case now drives /health through create_app() and
asserts the inbound id round-trips; mutation-checked by removing the wiring
line, which fails exactly this test.

* docs(gateway): note the fallback 500 is CORS-opaque

The pre-response 500 is emitted outside CORSMiddleware — the exception has
already unwound past it — so it carries no Access-Control-Allow-Origin and
a split-origin browser client cannot read the id on this one response,
unchanged from the ServerErrorMiddleware 500 it replaces. Documented on the
class and in the CHANGELOG entry rather than fixed: replicating the origin
allowlist outside CORSMiddleware would let the two policies drift.

* fix(harness): keep abandoned-stream cleanup inside the trace binding

stream() binds the turn's id around each next(inner) and resets it before
yielding, but the finally's inner.close() ran after that binding was gone.
Abandoning the stream therefore drove the inner LangGraph generator's
GeneratorExit/finally path with no trace id — or an unrelated ambient one
from whichever context ran the close — so cancellation and finalization
logs and callbacks did not correlate with the turn they belong to.

inner.close() is now wrapped in a local bind/reset of the same turn id. The
token is set and reset in the same frame, never across a yield, so the
per-step cross-context safety is preserved even when GC closes the
generator from another Context — pinned by the existing copy_context close
test, which now exercises this path. The regression test records the id
from the inner generator's finally and fails without the binding.

* test(harness): teach the worker-trace fake about RunManager.cleanup

Upstream #5112 (bound gateway memory after terminal runs) added a
run_manager.cleanup(run_id) call to run_agent's finalization, so the
merge-commit CI run failed all five worker-trace-binding tests with
AttributeError on this PR's _FakeRunManager. The fake gains the same no-op
shape as its other methods.

* docs(gateway): bring the gateway AGENTS.md back under its soft budget

Upstream #5092 grew backend/app/gateway/AGENTS.md to 40,966 bytes, 6 over
the 40,960 soft budget that
test_agent_guidance_check.py::test_repository_guidance_stays_below_soft_budgets_and_avoids_doc_indexes
enforces — its Unit Tests run on main was cancelled by push concurrency, so
main is currently red on that test and every PR merge-run inherits the
failure. Two whitespace/wording trims in the row #5092 touched (a doubled
space, and "its configured `context_window`" → "its `context_window`")
bring the file to 40,953 with no content change.

fix(runs): reject cancel actions on GET stream joins (#5092)
* fix(runs): reject cancel actions on GET stream joins

stream_existing_run is registered for both GET and POST, and its
?action=interrupt|rollback branch cancels the run. The CSRF middleware
exempts GET, so a session-authenticated browser could be forced
cross-site (img/script/top-level navigation) into
GET /api/threads/{id}/runs/{run_id}/stream?action=interrupt|rollback —
a state-changing GET that bypasses the CSRF protection guarding the
POST variant. Introduced with the dual registration in #1403.

The handler's docstring already documents cancel-then-stream as
POST-only (the LangGraph SDK's joinStream/useStream stop button uses
POST); enforce it: GET with an action answers 405, action-less GET
joins and POST cancel-then-stream are unchanged.

Regression drives the real router: GET+action is 405 with the run left
running, plain GET join still streams, POST+action still cancels.

* fix(runs): scope the 405 detail to the action requirement

"GET is a read-only stream join" overstates the current main: on a
locally-owned run with the default on_disconnect=cancel, a GET join's
disconnect can still trigger cancellation. That observer-disconnect
vector is closed by #5041; the detail here should only claim what this
guard enforces.

* fix(runs): harden GET stream action rejection

* fix(runs): align stream schema with method contract

* test(runs): pin GET stream action 405 through the production stack

Review follow-up (defence-in-depth): the GET-action suite drove bare
FastAPI() apps, so nothing pinned that a session-authenticated
cross-site GET reaches the route gate at all once CSRF exempts the
safe method. test_pat_auth.py already assembles the production
middleware order (AuthMiddleware inner, CSRFMiddleware outer), so its
mirror app now registers the real _reject_get_stream_action
dependency on a GET join route.

The new case pins the end-to-end premise: an authenticated GET
?action=interrupt is answered 405 + Allow: POST by the production
route dependency, while the same unauthenticated GET dies at
AuthMiddleware's 401 before any route logic runs.

Validation: focused suites (test_pat_auth, test_stream_get_action,
test_csrf_middleware) — 62 passed; ruff check + format clean; the new
case errors on the pre-fix baseline (guard absent), confirming the
pin.

feat(auth): add personal access tokens for programmatic API access (#5041)
* feat(auth): add personal access tokens for programmatic API access (#4849)

Backend-first implementation of the PAT contract from #4849: show-once
dfp_ tokens bound to their owning user (AUTH_SOURCE_PAT,
is_internal=false), digest-only storage (migration 0017), strict
credential precedence (invalid Bearer is a 401, never cookie fallback),
CSRF double-submit skipped only for Bearer requests while
auth-endpoint origin checks still run, scopes intersecting the authz
route permissions, session-auth-only PAT management and password
changes, and throttled best-effort last_used_at stamps.

* fix(auth): harden PAT scope boundary and schema parity from adversarial review

Independent review of the initial draft found: (1) scopes only constrained
the threads/runs permission axis while admin routes treated a PAT as its
(possibly admin) owner — is_admin_user now rejects PAT callers outright
since no scope grants admin capability; (2) the model declared a column
UNIQUE constraint while migration 0017 created a named unique index, so
downgrade failed on create_all-bootstrapped DBs — both now use the named
unique index; (3) auth-disabled mode is an operator override and now stays
ahead of the Bearer check so a stray Authorization header cannot 401 an
E2E sandbox; plus wiring the previously-unused constants, bounding the
last_used_at stamp cache, and four new tests (middleware-level expiry,
expires_in_days, admin-capability rejection with session control, and the
auth-disabled precedence).

* docs(api): document personal access tokens for programmatic API access

* fix(auth): close PAT security boundaries from review (default-deny routes, extension admin suppression)

P1-1: scope intersection only constrains @require_permission routes, so
undecorated mutation routes (DELETE /api/memory, POST /api/agents, Lark
credential switching, channel config) accepted a PAT holding a single read
scope. AuthMiddleware now enforces a default-deny route policy in
auth/pat.py: PAT requests are admitted only to the thread/run lifecycle
routes the v1 scopes govern; everything else answers 403 regardless of
scopes. Session-cookie callers are unaffected.

P1-2: the extension principal resolver projected is_admin/roles from the
raw system_role, so an admin-owned PAT passed
deerflow_extension_api.require_admin on contributed routes despite the
documented no-admin guarantee. The projection is now PAT-aware and
suppresses every admin signal for PAT callers, mirroring
deps.is_admin_user.

Both fixes carry regression tests (route outside policy 403 + session
control; production resolver admin suppression), and API.md documents the
default-deny boundary.

* fix(auth): enforce PAT scopes on stateless run entry and harden decorator

Follow-up hardening from an independent audit of the P1 fixes:

- POST /api/runs/stream and /api/runs/wait were the only allowlisted run
  entrypoints without @require_permission, so a threads:read-only PAT
  could still start runs (same bug class as P1-1, now closed): both now
  carry @require_permission("runs", "create"). POST /api/threads and
  POST /api/threads/search gain threads:write / threads:read for the
  same reason. Authorization-disabled deployments see no change (the
  permission set resolves to all permissions).
- require_permission now binds the wrapped signature to locate a
  positionally-passed request before injecting the test stub, fixing
  'got multiple values for argument' on direct positional unit-test
  calls.
- API.md: the intro PAT example used GET /api/models, which the new
  default-deny policy 403s — replaced with GET /api/threads; the
  default-deny route list now spells out method sets.

Regression test: threads:read-only PAT is 403 on the decorated stateless
entry while a runs:create PAT passes.

* fix(auth): address review P2s (empty Authorization header, PAT name trimming, API example)

- CSRFMiddleware treats an explicitly empty Authorization header as
  present (is None), so an invalid credential always reaches
  AuthMiddleware's uniform 401 instead of a CSRF 403 that varies by
  method/CSRF state. Regression: empty-header request dies at auth.
- PATCreateRequest strips the name and rejects whitespace-only values
  before token generation; created names are stored trimmed.
- API.md intro PAT example now uses the implemented
  POST /api/threads/search endpoint (GET /api/threads does not exist).
- AGENTS.md trimmed back under the guidance soft budget after the
  upstream merge.

* fix(auth): tighten PAT route policy to implemented methods only

The allowlist admitted GET /api/threads, a method no router implements.
Pre-authorizing a dead method weakens the default-deny boundary: a
future GET collection route added without a permission decorator would
become PAT-reachable without an explicit policy change. Restrict the
rule to POST, fix the stale GET description in API.md's PAT
constraints, and document the default-deny boundary accurately in the
gateway AGENTS.md guidance (only the threads/runs allowlist is
PAT-reachable; every other authenticated route 403s PAT callers).

Audited every remaining rule against the mounted routers: all other
method+path entries map to real routes. Regression:
test_pat_policy_does_not_pre_authorize_unimplemented_methods.

* test(auth): guarantee the negative digest test mutates the token

token[:-1] + "X" is identical to the original whenever the generated
token already ends in X (1/62), making the negative digest assertion
fail intermittently. Choose the replacement character based on the
existing tail so the mutated token always differs.

* fix(auth): require runs:cancel for cancel-then-stream requests

stream_existing_run is gated at runs:read so action-less stream joins
work with read-only credentials, but its ?action=interrupt|rollback
branch cancels the run — a separate permission. A runs:read-only PAT
passed both the PAT route policy and the route decorator and could
interrupt or roll back an active run, bypassing the runs:cancel scope.

Decorators cannot express query-parameter-conditional permissions, so
the check lives in require_cancel_permission_when_action(), applied at
the top of the handler. Regression drives the real helper through the
production middleware: runs:read-only PAT + action is 403, the same
token joins action-less, runs:read+cancel passes, session control
unaffected.

* docs(changelog): add the PAT feature entry

* docs(readme): add personal access tokens section

Repo documentation-update policy requires user-facing features to
update README.md in the same changeset; the PAT feature previously
touched only backend/docs/API.md and the gateway AGENTS.md.

* fix(auth): require runs:cancel for mutating multitask strategies

All five run-creation entrypoints were gated only by runs:create, but
RunCreateRequest.multitask_strategy accepts interrupt/rollback and
start_run forwards it to create_or_reject, which terminates an
already-active run. A runs:create-only PAT could therefore kill an
existing run through a create request, bypassing runs:cancel.

Decorators cannot express body-parameter-conditional permissions, and
per-route checks leave the same hole for the next entrypoint, so the
gate lives in start_run itself — the single choke point every
run-creation path (HTTP routes and internal launchers) flows through.
Regenerate launches pass multitask_strategy="reject" and are
unaffected; requests without a stamped auth context (internal/test
compositions) skip the gate.

The check is the shared authz.require_cancel_permission_if primitive;
require_cancel_permission_when_action now delegates to it, so every
request dimension that carries cancel capability (query action, body
strategy) flows through one gate.

Regression drives the real middleware stack: runs:create-only PAT +
interrupt/rollback is 403 with the exact detail, reject (explicit and
default) stays available, runs:create+cancel passes, session control
unaffected; a source anchor pins the gate inside start_run.

* fix(runs): keep observer joins from applying creator cancel-on-disconnect

sse_consumer's finally block applied the record's on_disconnect=cancel
policy on ANY consumer's disconnect. The join surfaces (GET /join and
the action-less GET/POST stream join) feed it the existing RunRecord,
so anyone with thread read access — including a runs:read-only PAT —
could cancel a locally-owned running run simply by closing the SSE
connection, without runs:cancel. The policy expresses the creator's
intent for their own connection; an observer's disconnect must never
be read as that intent.

sse_consumer gains apply_on_disconnect (default True). The two join
surfaces pass False; the creating endpoints (thread-scoped and
stateless create-and-stream) keep the creator semantics unchanged.
wait_for_run_completion needs no change: its callers are creator-side
or post-explicit-cancel paths only.

Regression exercises a real generator close — the same machinery
Starlette drives on client disconnect — against the production
sse_consumer: creator stream disconnect cancels, observer join
disconnect does not; a wiring anchor pins both join call sites and the
creator defaults. API.md documents the cancel-capability constraint
(this fix plus the action/strategy gates) in PAT Constraints.

* test(auth): pin the multitask gate behaviorally; state wait invariant

Independent adversarial review of the round-5 fixes found the P1-a
regression only mirror-pinned: the source anchor could be satisfied by
a comment, and deleting the gate from start_run would not fail the
suite. This drives the production start_run directly — a create-only
auth context gets 403 with the exact detail for interrupt, and a
reject request with no cancel permission at all proceeds past the gate
(never a permission 403).

Also documents wait_for_run_completion's creator-side invariant
(every caller is the creating endpoint or post-explicit-cancel) so a
future observer wiring thinks twice before reusing it — the one-caller-
away variant of the observer-disconnect P1.

* docs(changelog): correct the PAT entry's digest and route-policy description

The entry said HMAC digests (the implementation stores SHA-256 digests,
as documented in API.md and pinned by the repository tests) and claimed
the route policy admits 'implemented stateless endpoints' (it admits
the thread/run lifecycle routes, narrowing further by scopes). Also
notes the cancel-capability gate now covering action and multitask
strategies.

* fix(auth): enumerate the PAT runs route policy per implemented subroute

The runs subtree rule was a GET|POST /runs(/.*)? wildcard — it
pre-authorized every current and future subroute under /runs, including
methods the router never implemented (e.g. GET /runs/stream), which is
the same latent default-deny weakening the threads collection rule was
tightened for: a future route added under /runs would become
PAT-reachable without an explicit policy change.

The wildcard is replaced with six segment-precise rules covering exactly
the 14 implemented method+path combinations; the {run_id} slot
necessarily matches any single segment, so the POST-only collection
names (stream, wait, regenerate, edit-regenerate) are excluded from the
GET run-id rule via negative lookahead — no dead method stays
pre-authorized. Behavior for implemented routes is unchanged.

test_pat_runs_policy_admits_exactly_the_mounted_routes derives the
expected set from the mounted thread_runs router instead of a
hand-maintained list: every implemented GET/POST route under /runs must
be admitted, routes in this router outside the subtree stay denied, and
representative unimplemented neighbors are denied — so adding a route
under /runs now fails CI until it is explicitly allowlisted, and a
removed route leaves a dead rule visible. API.md's PAT constraints list
the enumerated routes and drops a feedback mention that belonged to the
stateless /api/runs axis.

* docs(migration): add the 0017 renumbering coordination note to 0017

The PR's migration-coordination comment states each migration file
carries the note; the file did not. Adds it: numbering was generated
against main head 0016 alongside #5078 and #4843; whoever merges first
keeps the slot, the others renumber on rebase (revision/down_revision
plus the bootstrap head assertions).

* fix(auth): pad base62 tokens to a fixed 43-char width

int.from_bytes discards leading zero bytes, so the unpadded encoder
returned a variable-length body — empty for all-zero input, and shorter
than 40 characters for any draw below 62**39 (~1 in 14.5M), leaving
test_generate_pat_token_format probabilistically flaky and the token
body without stable width (review round 6, P3).

_base62 now left-pads with "0" to _base62_width(len(data)) — the exact
integer digit count (62^43 > 2^256 > 62^42, so 43 for 32 bytes). The
format test asserts the exact fixed width instead of a probabilistic
floor, and a new unit test pins the all-zero, leading-zero-byte, and
max-value edges deterministically.
