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. |

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. |

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. |

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. --------- Co-authored-by: Totoro-qaq <279883115+Totoro-qaq@users.noreply.github.com> |

fix(skills): stop persisting resolved secrets when toggling skills (#5357)
Toggling a skill wrote resolved secrets into extensions_config.json. The Gateway skill toggle and DeerFlowClient.update_skill loaded the file with ExtensionsConfig.from_file(), which replaces every "$VAR" string with the environment value (and an unset variable with ""), then serialized that model back through to_file_dict(). A "$GITHUB_TOKEN" reference was persisted as the plaintext token, and an unset reference was erased for good. DeerFlowClient.update_mcp_config had the same flaw for every key other than mcpServers. Every writer now does a raw read-modify-write, the way the MCP router already did: read_raw_extensions_config reads the on-disk JSON, set_raw_skill_enabled changes only the target entry, and validate_raw_extensions_config checks the candidate the way the runtime will load it before the atomic write. When the file does not exist yet, the Gateway seeds it with the cached skill states only, never the resolved cached model. The MCP router's raw loader and candidate validation delegate to the same helpers, so the rule lives in one place, and to_file_dict() is removed so the unsafe serialization has no entry point left.

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(tools): run tool assembly off-loop at async entry points (#5224)
* fix(tools): run tool assembly off-loop at async entry points get_available_tools() may block on MCP cache initialization while it is called on async agent-assembly paths (task_tool, durable batch execution), stalling the calling event loop for the full discovery duration. Dispatch the (unchanged, synchronous) assembly call to a worker thread via asyncio.to_thread at the two async entry points so the loop keeps processing requests, SSE frames, cancellations, and timers. Fixes #5172 * fix(tools): offload lead-agent assembly off-loop and pin with blocking-io anchors Review follow-up for #5224: - run_agent now dispatches agent_factory(...) through asyncio.to_thread, so lead-agent assembly (including both get_available_tools call sites in _assemble_lead_agent) runs off the event loop — the Gateway headline scenario from issue #5172. - _ensure_sync_invocable_tool takes a double-checked threading.Lock, making the in-place tool.func wrap on the shared tool singletons explicitly single-shot now that assembly can run concurrently on worker threads. - Add backend/tests/blocking_io/test_tool_assembly_offloop.py: blocking-probe anchors for task_tool and SubagentBatchService._execute_item under the strict Blockbuster gate, plus a meta-check proving the gate trips on the exact syscall class (ExtensionsConfig.from_file on the loop). Verified the anchor goes red when the offload is flattened back to a plain call. * fix(gateway): build checkpoint state accessor off-loop; anchor run_agent offload Review follow-up for #5224: - Add abuild_checkpoint_state_accessor (asyncio.to_thread around the unchanged sync builder) and switch every async call site to it: the stateless_wait route, thread_runs, both threads call sites, and the build_thread_checkpoint_state_accessor boundary. The agent-factory assembly re-enters get_available_tools() and may block on MCP cache initialization; repeat calls hit _state_accessor_graph_cache and only pay the thread hop. - Add a third blocking-io anchor driving the real run_agent with minimal RunManager/bridge stubs; the factory performs a real production blocking read (ExtensionsConfig.from_file()) and the test asserts assembly never runs on the main thread. Verified the anchor goes red when the run_agent offload is flattened back to a plain call. - Adapt the test_threads_router checkpoint-builder patch sites to the new async name. * refactor(tools): carry assembly offloads on a dedicated bounded pool Review follow-up for #5224: - Add utils/assembly_io.py: a dedicated ThreadPoolExecutor (default 8 workers, DEER_FLOW_ASSEMBLY_WORKERS-overridable, mirroring utils/file_io.py and tools/sync.py) with run_assembly(), which copies contextvars explicitly. A hung stdio MCP server parks its worker for the full MCP timeout; carrying assembly hops on the loop's default executor would let a few parked assemblies queue every other to_thread/run_in_executor(None, ...) caller behind them. - Switch all four offloads (run_agent, task_tool, batch _execute_item, abuild_checkpoint_state_accessor) to run_assembly(). - State the cold-path behavior in the accessor docstring: the graph cache validates factory identity, so non-identity-stable factories may duplicate lead-agent assembly across concurrent readers (MCP discovery stays process-wide single-flight); the pool bounds the duplicates. - Add a fourth blocking-io anchor driving build_thread_checkpoint_state_ accessor with a per-resolution fresh factory (always a cache miss) and the real production blocking read; enumerate all four offloads in the gate's module docstring. Verified the anchor goes red when abuild_checkpoint_state_accessor is flattened back to a plain call. * fix(subagents): revalidate batch item before launch; make assembly pool observable Review follow-up for #5224: - _execute_item() revalidates the durable state right after assembly and before executor.execute_async(): renew_item_lease() returns valid=False when cancel_batch() terminalized the item or the lease was lost while assembly was parked, and the launch is skipped (the canceller already finalized the item). Previously the launch was unconditional and the poll loop's cancellation checks only started after execution began. - Regression test driving the real SQLite repository: a blocking assembly probe parks _execute_item, cancel_batch() lands, and the launch is skipped with the item staying cancelled. Verified the test goes red when the revalidation is removed. - run_assembly() tracks pending assemblies and logs a throttled WARNING once the pending count exceeds the worker count, so assembly starvation (workers parked on a hung MCP server) is distinguishable from idle. - The run_agent blocking-io anchor now binds a sentinel extension snapshot via ctx.extensions and asserts the factory observed it through get_agent_build_extensions(), pinning run_assembly()'s ContextVar propagation. Verified red when ctx.run is dropped. - Document the assembly pool in backend/AGENTS.md. * fix(utils): decrement the assembly pending count on the pool thread The pending-assembly counter behind the starvation warning decremented from the asyncio future's done callback, which never fires once the submitting loop is closed while its worker is still running: the count ratcheted up permanently and eventually fired the starvation warning with no starvation behind it (reproduced at 97dc9bec by review). Decrement instead from the dispatched work item: run_assembly() wraps func so a finally drops the count under the pending lock on the pool thread, and the done callback is gone. Pin the counter with tests/test_assembly_io.py: a healthy call returns the count to zero, and an abandoned loop (stopped while the worker is parked) does not wedge it — the abandoned case goes red against the old done-callback decrement. * docs(utils): fix the pending-counter comment after the decrement move The comment still described the removed done-callback decrement, contradicting _work()'s own comment; state the actual mechanism (increment on the loop before dispatch, decrement from the dispatched work item's finally on a pool thread). * test(gateway): retarget checkpoint-accessor stubs to the services seam thread_runs and runs now call abuild_checkpoint_state_accessor, so the upstream wait-reader, regenerate-prepare, and idempotency tests must stub the sync builder where abuild resolves it (app.gateway.services); stubbing the removed router re-exports fails with AttributeError at setup. The async seam semantics are unchanged: run_assembly invokes the stubbed sync builder off-loop and propagates its return values and exceptions. Move the agent/tool assembly off-load note from backend/AGENTS.md to deerflow/utils/AGENTS.md (next to assembly_io.py) so the effective instruction chain for agents/middlewares no longer grows past the AG002 hard limit. * fix(runtime): serialize same-key accessor assembly and release queued-cancel slots Address the three review follow-ups on the assembly off-load: - assembly_io: a job cancelled while still queued never runs its work item, so the dispatched finally never fired and _pending_assemblies stayed elevated until a false starvation warning. Exactly-once cleanup now rides the concurrent future's cancelled() state — cancel() only succeeds before the executor starts the item, so cancelled() is true precisely when the finally will never run — plus a submit-failure release; the one-worker queued-cancellation case is pinned red/green. - services: overlapping cold readers sharing one cache key could both run full agent assembly. _state_accessor_graph now serializes per key through a thread-side KeyedLockTable (pool threads, no running loop) and re-validates factory/app-config identity under the lock, so the factory runs exactly once while identity changes still rebuild. Cache dict access is lock-guarded now that construction runs off-loop. - guidance inventory: register deerflow/utils/AGENTS.md in EXPECTED_GUIDANCE_PATHS so test_repository_has_the_approved_scoped_ guidance_shape matches the relocated assembly note (CI shard 4). * test(keyed-lock): pin KeyedLockTable reclamation and waiter bypass directly Thread-side counterparts of the async table's own tests: overlapping hold() calls serialize (a late arrival joins the live entry instead of creating a second lock that bypasses a queued waiter), the last check-in pops the entry, and many unique keys leave the registry empty. Both regressions verified red — popping unconditionally trips the late-arrival test, never reclaiming trips the many-keys test. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(scheduler): add interval schedule type (#5291)
* feat(scheduler): add interval schedule type Allow scheduled tasks to fire every N seconds from last dispatch, not only wall-clock cron or a single run_at. Cadence is UTC now+N with no missed-beat catch-up, bounded by min_once_delay_seconds and 30 days. * fix(scheduler): let interval tasks create, edit, and keep next run Create/edit now keep every_seconds. Unchanged interval spec no longer resets next_run_at, including timezone-only PATCH. * fix(scheduler): keep non-minute intervals on edit Stop rounding every_seconds to whole minutes in the form.

feat(scheduler): let scheduled tasks pin a custom agent (#5288)
* feat(scheduler): let scheduled tasks pin a custom agent Create and update accept optional assistant_id, defaulting to lead_agent. Custom names are normalized and must already exist for the task owner. The workspace form exposes the same choice, and duplicate copies it. Fixes #5286 * fix(scheduler): keep assistant-id PR free of interval tests Drop the six interval tests that belonged to the interval schedule PR and fail here because this tree still only accepts once/cron. Treat lead_agent case-insensitively so LEAD_AGENT / lead-agent store as the default. Omit unchanged assistant_id on edit so a deleted custom agent does not 422 unrelated PATCH (rename, reschedule). * fix(scheduler): format task page and browser tests --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

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.
* fix(projects): validate forward schemas and fence membership reads

feat(authz): surface effective route permissions on GET /auth/me (Phase 4, #4063) (#5228)
* feat(authz): surface effective route permissions on GET /auth/me (Phase 4, #4063) GET /api/v1/auth/me now returns the effective route permissions alongside the user identity, so the frontend can hide actions the caller's role cannot perform (RFC #4063 Phase 4). The value reuses the AuthContext that AuthMiddleware already resolves per request (including PAT-scope intersection and internal-caller semantics), so /me adds zero extra provider evaluations; a middleware-less composition falls back to the same resolution _authenticate uses. Credential-creation responses (register/initialize) leave the field None: they are public paths where the middleware does not run, and resolving there would introduce fresh on-loop config loads on those routes. * test(e2e): expect /auth/me permissions in auth-disabled contract PR #5228 adds the effective route permissions to GET /auth/me, so the strict toEqual against the bare AUTH_DISABLED_USER object no longer holds: the received payload carries six extra keys (the permissions array). Extend the expected payload with the full registered permission set in _ALL_PERMISSIONS order — with authorization disabled the gateway grants exactly that static list, so the pin stays deterministic. The runtime frontend is unaffected (auth-disabled SSR never calls /me, and userSchema strips unknown keys); only this contract pin needed the new field. * refactor(authz): public resolve_route_permissions_for_request wrapper Address review nits on the middleware-less fallback: the router reached into the private authz._is_internal_caller, so expose a thin public wrapper pairing resolve_route_permissions with the internal-caller heuristics, and use it from both _authenticate and the /me fallback so the two cannot drift apart. Also drop an unused tmp_path parameter from test_auth_disabled_me_includes_default_admin_permissions (_setup_auth provisions its own tmp directory). No behavior change: the wrapper delegates to the exact pair of calls the fallback made before. |

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(auth): make login rate-limit parameters configurable, fixes #5108 (#5110)
* feat(auth): make login rate-limit parameters configurable, fixes #5108 Add auth.local.max_login_attempts (default 5) and auth.local.lockout_seconds (default 300) so operators can tune the per-IP login throttle: raise the ceiling for shared-egress-IP offices behind proxies/NAT, or tighten it for stricter posture. Policy is live-read per call (matching the _local_registration_enabled precedent), so a config reload applies without a Gateway restart; raising the threshold mid-lockout immediately unblocks affected IPs. Review feedback addressed (willem-bd): - Only FileNotFoundError falls back to the hardcoded defaults; a malformed config propagates, mirroring _local_registration_enabled, so an operator who tightened the policy never silently gets the more permissive defaults. - _check_rate_limit looks up the record before resolving the policy, so a clean IP pays zero config reads (get_app_config re-hashes config.yaml per call and login_local is an unauthenticated async endpoint). Bumps config_version to 39 in config.example.yaml and the Helm chart (values.yaml + README example) so the chart drift check stays green. * fix(auth): reject max_login_attempts=1 and honor live lockout_seconds for active lockouts * fix(auth): close live-policy state gaps in login throttle (resurrection, count reset, broken-config verification) * fix(auth): commit evaluated lockout duration on decreases too, preventing raise-resurrection * test(auth): pin broken-config fail-closed sequence through the login route * fix(auth): sweep expired locks by stored sentence and keep policy reads off the event loop * fix(auth): re-read throttle record after the policy-resolution yield point --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(history): early user messages vanish or jump mid-run when pagination and context compaction overlap (#4696)
* fix(history): stop dropping user messages that fall outside the loaded page window Two independent paths made a user's own message disappear from a long thread (#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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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.

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. |

feat(mcp): map request-scoped secrets to MCP HTTP/SSE headers (#5010)
* feat(mcp): map request-scoped secrets to HTTP/SSE headers `user_auth` binds a credential to a configured DeerFlow user, so a caller that picks the credential per request — a multi-tenant gateway, a per-run API key, one shared MCP server fronting several environments — had to register one MCP server entry per credential. Add a declarative `mcpServers.<server>.headers_from_context` block mapping HTTP header names to keys of the run request's `config.context.secrets` carrier. A new built-in interceptor resolves the mapping on every tool call and rewrites those headers, mirroring `user_scoped_auth`. The config file stores names only, never a credential, so the Gateway returns the block unmasked. Registered after OAuth and `user_auth` in the interceptor chain: the later interceptor runs closer to the transport, and the value chosen for this one request is the most specific, so it wins. Fail-closed by default — a mapped key missing from the request raises a `ToolException` naming only that key, because falling back to the server's discovery credential would send one tenant's call under another tenant's authority. `on_missing: "passthrough"` opts out. Durable background tasks are excluded: `McpTaskToolCaller` drives status and cancel polls after the Agent run ends, where no run context exists, so the fail-closed interceptor would deny every poll. Those calls keep using server-level credentials, and a server declaring both `headers_from_context` and `task_toolsets` now logs a warning. Also corrects the custom-interceptor example in docs/MCP_SERVER.md (and the matching claim in skills/AGENTS.md), which read request secrets from `langgraph.config.get_config()["context"]`. That key is `None` inside a tool call — the run context rides the LangGraph runtime, not the RunnableConfig propagated to child runnables — so interceptors written from that example never saw a value. The example now reads `request.runtime`, and tests/test_mcp_context_headers.py pins LangGraph's runtime-injection rule by driving a real langchain-mcp-adapters tool through a real graph with the ambient-runtime fallback disabled. Closes #5005 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(mcp): resolve credential headers case-insensitively, carry them on durable submit Review follow-ups on `headers_from_context`. HTTP field names are case-insensitive, but every dict on the path to the wire is not: `build_server_params` copies the operator's static `headers` spelling verbatim, and langchain-mcp-adapters merges interceptor overrides into the connection with a plain `{**connection_headers, **override_headers}` splat. A static `authorization` and an injected `Authorization` therefore both reached httpx as separate field lines, and a server reading the field with a single-value accessor got the static discovery credential — inverting the documented `headers` < `oauth` < `user_auth` < `headers_from_context` precedence and running a per-request call under the shared credential. Normalizing inside the interceptor cannot fix that on its own: the adapter builds the request with `headers=None`, so an interceptor never sees the connection's static headers and cannot displace them however it spells its own key. A new `mcp/headers.py::apply_header_overrides` therefore drops any key differing only in case and emits the spelling the connection already uses. Applied to `headers_from_context`, `user_auth`, the OAuth interceptor, the OAuth discovery-header write, and the durable-task connection merge, which all carried the same collision. `headers_from_context.headers` now also rejects one header mapped under two spellings at config load, in both the harness model and the Gateway mirror. Durable submit now carries the mapped headers, as docs/MCP_SERVER.md already promised. `McpTaskToolCaller` disabled the interceptor for the whole caller, but that caller serves submit as well as the polls, and submit is awaited inline inside the Agent's tool call — where the run's LangGraph runtime is still the ambient contextvar, so no secret has to be threaded through `TaskSubmitRequest` or reach durable storage. The caller builds one chain and keeps a second view of it without the context-headers interceptor; `call_tool` takes `request_scoped_headers`, set only by `OrdinaryMcpTaskDriver.submit`. Status and cancel keep server-level credentials, so background polls still cannot fail closed, and the startup warning now describes the half it actually covers. `_merge_preserving_secrets` restores masked extras inside `headers_from_context` instead of writing the `***` sentinel back over the stored value, matching the treatment `user_auth` extras and server-level extras already get; extras a PUT omits carry over as well, while the declared mapping still replaces verbatim so a round trip can remove an entry. `extra="allow"` plus name-based sensitivity detection means the usual casualty is a name-valued key such as `tokenHeader`, not only a credential. The existing override test seeded the static header onto `request.headers`, which production never does, so it modelled a merge that really happens one layer down; the new tests drive a real adapter tool through a real connection and assert on the headers the session is opened with, and the durable-submit test runs through a real tool node with no runtime patching.

feat(authz): enforce sandbox:execute authorization at sandbox acquisition (#4063 Phase 3) (#4911)
Sandbox is an execution environment, not a named resource: multiple tools
(bash, read_file, write_file, glob, grep, ...) depend on it, all funneled
through ensure_sandbox_initialized / ensure_sandbox_initialized_async. Gate
the single acquisition entry point (single source of truth) instead of
maintaining a sandbox-tool-name set in middleware:
- authorize_sandbox_execution helper (authz/sandbox_authz.py) checks
authorize("sandbox", "execute", target="*") — a binary judgment
(can this role use the sandbox at all); RBAC allow:"*"/true permits,
allow:[]/false denies.
- lazy path: ensure_sandbox_initialized (+ async) calls the gate before
provider.acquire.
- eager path: SandboxMiddleware.before_agent / abefore_agent call the gate
before _acquire_sandbox.
- deny raises SandboxAuthorizationError (SandboxError subclass) which
propagates through tool execution as a friendly ToolMessage (RFC §9:
'not a crash').
- authorization.enabled: false is a no-op everywhere; provider errors
follow fail_closed (deny) / fail_open (allow).
12 tests in tests/test_sandbox_authorization.py cover disabled/allow/deny/
deny-via-bool/no-policy-unrestricted/provider-error-fail-closed/open/
internal-caller + ensure_sandbox_initialized deny (never acquires) and
allow (acquires) integration paths.

fix(artifacts): serve SHA-256 via ETag so preview/edit work on non-secure contexts (#4865)
* fix(artifacts): serve SHA-256 via ETag so preview/edit work on non-secure contexts crypto.subtle is only available in secure contexts (HTTPS or localhost). The frontend fell back to it to compute an artifact's SHA-256 when the Gateway did not return one, which threw on http://<lan-ip>:<port> and broke both artifact preview and inline editing (issue #4864). - Gateway now returns the real SHA-256 as an ETag header for inline text and active-content artifact responses (and skill-archive members). - Frontend prefers the ETag and only computes a hash as a last resort, falling back gracefully (FNV-1a) instead of throwing when crypto.subtle is missing. * fix(artifacts): address PR review feedback for #4864 - Cache SHA-256 digests by (path, mtime_ns, size) so the many small Range requests a browser issues while scrubbing/paginating a preview do not each re-hash a potentially huge artifact from scratch (performance). - Gate inline editing on a real 64-hex revision: hasRevision requires sha256.length === 64, so the FNV-1a fallback on non-secure origins keeps preview working but no longer 422s on save (contract). - Anchor and lowercase the ETag regex and accept the weak W/ prefix gzip emits, so uppercase hex and longer digests (sha-384/512) can't masquerade as sha-256. - Cover the forced-download ETag on the backend and add frontend tests for weak-ETag parsing and the non-secure-context FNV fallback. Feedback from reviewer willem-bd on PR #4865. * style: fix ruff format and prettier issues - test_artifacts_router.py: collapse two over-split client.get() calls to satisfy ruff format (line-length 240) - loader.ts / artifact-file-detail.tsx / loader.test.ts: apply prettier formatting and restore LF line endings * style: fix ruff format and prettier issues - test_artifacts_router.py: collapse two over-split client.get() calls to satisfy ruff format (line-length 240) - loader.ts / artifact-file-detail.tsx / loader.test.ts: apply prettier formatting and restore LF line endings * style: fix ruff format and prettier issues - test_artifacts_router.py: collapse two over-split client.get() calls to satisfy ruff format (line-length 240) - loader.ts / artifact-file-detail.tsx / loader.test.ts: apply prettier formatting and restore LF line endings * style: fix ruff format and prettier issues - test_artifacts_router.py: collapse two over-split client.get() calls to satisfy ruff format (line-length 240) - loader.ts / artifact-file-detail.tsx / loader.test.ts: apply prettier formatting and restore LF line endings * style: reformat artifact-file-detail.tsx for prettier with tailwind class ordering * fix: invalidate SHA-256 cache after artifact edit Clear the LRU cache after os.replace() so the next preview request computes the new digest.

fix(gateway): reject MCP task cancellation when the worker is stopped (#4963)
The cancel endpoint resolved McpTaskService whenever SQL persistence was configured, even with mcp_tasks.enabled=false, and acknowledged the request by recording cancel_requested_at. The background loop that owns the remote cancel call only runs when enabled, so the fence was never claimed and the remote task kept running indefinitely. Gate the endpoint on app.state.mcp_tasks_available (set only after the service is started) and return 503 before writing the fence, consistent with the background-loop ownership contract. Read-only list/detail endpoints remain available while the worker is stopped. |

feat(mcp): per-user credential injection for shared MCP servers (#4868)
* feat(mcp): per-user credential injection for shared MCP servers
A single HTTP/SSE MCP server entry can now serve several users, each
authenticated to the remote service with their own credential. A server
opts in with a user_auth block mapping user ids to credential header
values ($ENV_VAR references supported):
"user_auth": {
"header": "Authorization",
"users": { "<user-id>": "$SERVICE_TOKEN_ALICE" }
}
The built-in user-scoped auth interceptor resolves the authenticated
runtime user on every tool call (request runtime -> ambient LangGraph
runtime -> auth config -> request-scoped user ContextVar) and rewrites
the configured header via request.override(), the same per-call
mechanism as the OAuth interceptor. It registers after OAuth in the
shared assembly so its per-user value wins the header when a server
declares both. The entry's static headers are used only for startup
tool discovery.
Fail-closed by default: an unmapped user - including the anonymous
default-user fallback - or a credential whose env reference resolved
empty gets an actionable ToolException instead of another user's
credential; on_missing: "passthrough" opts out per server. Combined
with the existing per-(user, thread) MCP session scoping this gives
credential isolation on shared servers.
Gateway API: user_auth.users values are masked in GET responses, and
PUT round-trips preserve stored credentials for masked values (same
contract as env/headers/oauth secrets); a masked value for a user id
not already stored is rejected.

* fix(mcp): address review — preserve stored user_auth sub-fields on partial PUT, warn-and-skip stdio, allow extras
Review findings from #4868:
1. A partial user_auth payload (e.g. {"enabled": false}) merged to
users={} and default on_missing, irreversibly wiping stored
credentials on PUT. The merge is now sub-field-aware via
model_fields_set — omitted sub-fields carry the stored values, an
explicitly sent users map still replaces (so full-round-trip removal
works), masked values still swap back for stored credentials.
2. user_auth on a stdio server was a silent no-op: rewritten headers go
to call meta, never a transport header, while deny errors still fired.
The interceptor builder now warns and skips non-sse/http servers,
matching the tool_call_timeout transport-mismatch convention.
3. McpUserScopedAuthConfigResponse now allows extra keys like the
harness-side model, and extras survive masking and merge, matching
the server-level model_extra handling.
Adds four regression tests (partial-PUT preservation, explicit-map
replacement, extras round-trip, stdio warn-and-skip).

* fix(mcp): reject blank user_auth.header at the gateway
A blank header passed the gateway response model, was persisted, then
failed the harness-side ExtensionsConfig validator on reload — the PUT
returned 500 after the write and every later config load/startup failed
until the file was hand-edited. Mirror the harness non-blank validator
on McpUserScopedAuthConfigResponse so the PUT fails with 422 before
anything is written.

* fix(mcp): harden the trust chain and masking around user-scoped credential selection
Address review round 4:
- Scrub client-supplied user_id from run context/configurable for
external callers in inject_authenticated_user_context, before every
early return, and restamp only from request.state.user. Now that
user_id selects which user's credential user-scoped MCP auth injects,
a forged value must not survive any future path that skips the
restamp. Internal callers (IM channels, scheduler) keep supplying
end-user identity as before (PR #3294 contract). Regression tests pin
both the scrub and that a forged body.context.user_id can never
resolve as another user through merge + inject ordering.
- Include the caller's own resolved user id in the fail-closed deny
message so operators can copy the exact users key (it differs by
deployment path), and document the key formats in the mcp.mdx doc.
- Mask sensitive extra keys inside user_auth on GET like server-level
extras, and swap masked sentinels back for stored values on PUT via
_merge_extra_value_preserving_masked.
- Extract the interceptor wrap loop into compose_tool_interceptors and
pin the security property functionally: an OAuth interceptor that
actually sets Authorization loses the final header to the per-user
credential through the same composition the session-pool path uses.

fix(docker): let the Gateway write extensions_config.json in production (#4852)
* fix(docker): let the Gateway write extensions_config.json in production AGENTS.md states extensions_config.json may be edited at runtime through the Gateway API, and the Gateway implements that for the MCP enable switch, PUT/PATCH /api/mcp/config and the skill update route. Two properties of the production compose stack made every one of those writes fail: - the file was mounted read-only, and - Docker mounts it as its own mount point, so the temp-file-plus-rename in atomic_write_extensions_config hit EBUSY. Linux refuses rename() over a mount point whether or not the mount is writable, so making the mount read-write alone is not enough. Mount it read-write and fall back to an in-place overwrite on EBUSY only. The fallback is deliberately non-atomic and says so in a warning; it is reached only where the atomic route cannot work, and any other errno still propagates. config.yaml stays read-only: no API writes it. docker-compose-dev.yaml mounts the whole project directory, so the destination is an ordinary file there and this never surfaced in development. * test(docker): parse mount options instead of matching a :ro suffix Docker's short-syntax options segment is comma-separated, so a read-only mount can legally be spelled ":ro,z" or ":z,ro" — common with SELinux relabelling. Matching the raw string for a ":ro" suffix reads those as writable, which silently defeats the guard: the writability assertion would pass on a read-only mount, and the config.yaml assertion would fail on a correctly read-only one. Parse the options segment and test membership instead, and cover the parser with the spellings that broke the suffix check. * fix(config): harden mutable extensions config |

feat(extensions): let an out-of-tree extension observe what the agent did (#4863)
* feat(extensions): let an out-of-tree extension observe what the agent did
DeerFlow's extension system can contribute middleware, services and routes,
but an extension cannot answer basic questions about a run without reaching
into host internals. Several of the facts it would need are destroyed by the
operations that produce them:
* The middleware chain injects and rewrites a lot of context — date
reminders, recalled memory, compaction summaries, durable-context data,
image payloads, activated skill bodies. Downstream, none of it is
attributable: at the model-call boundary an injected HumanMessage is
indistinguishable from the user's own, and anything wanting to tell them
apart has to pattern-match prompt wording, which breaks on the next copy
edit.
* Two runs of "the same agent" are only comparable if the chain enforced the
same limits, prompts and thresholds. Recovering that from outside means
reading private attributes and guessing which of them change behaviour — a
guess that rots silently as middlewares gain fields.
* The lead-agent factory resolves a model after runtime overrides, renders a
prompt, filters tools through authorization and composes a stack, all
inside one synchronous call, and none of it survives: a middleware sees its
neighbours but not the prompt, the run worker sees a graph but not what
went into it.
* Summarization is destructive by design. N messages leave the context and
one summary enters it; afterwards only the summary exists, so "which
messages became this?" is not reconstructible.
This adds seven neutral facilities so those facts are recorded where they are
still true, and releases the contract package as 0.2.0.
Message provenance
Producers stamp `deerflow_content_kind` / `deerflow_producer_kind` onto the
messages they inject or rewrite. Stamping is unconditional — a fact whose
presence depends on whether an observer is installed is not a fact — and the
keys are server-owned, so provenance cannot be forged from a request.
Middleware self-description
Twelve middlewares declare their own behaviour-affecting parameters through
a duck-typed `release_policy_parameters()`. Long text is hashed rather than
embedded: a declaration is an identity, not a copy of the prompt.
Agent assembly descriptor
`assemble_lead_agent()` returns the graph plus a descriptor whose fingerprint
answers "did anything about this agent change between these two runs?".
`make_lead_agent()` keeps its graph-only signature — it is the LangGraph
Server ABI declared in langgraph.json. Tools and skills are sorted before
hashing because their assembly order is incidental; middlewares are not,
because stack order decides what wraps what. Host build identity is reported
but excluded from the fingerprint, so a redeploy does not invalidate every
agent's identity.
Context compaction observation
Summarization emits the content hashes of the messages it is about to remove
joined to the summary that replaced them. Content is the only identity
available at that seam: the summary does not become a message, and what later
projects it into a request renders it bounded and escaped rather than
verbatim.
Neutral policy, transform and MCP-source facts
Guardrail decisions are published to runtime context under a `__`-prefixed
key; result-rewriting middlewares append a declared, ordered transform trail;
MCP tools carry their credential-free logical origin.
Extension route identity
Contributed routes are session-authenticated and cannot opt out, but
"logged in" and "administrator" are different questions. Extensions get a
neutral projection of the caller rather than the host's auth context, and
`require_admin` fails closed when identity cannot be determined.
Extension-owned tables
An extension that persists data owns its own MetaData and migration chain, so
its tables are absent from Base.metadata and `alembic revision --autogenerate`
proposes dropping them. Extensions declare a table prefix, which is rejected
at registration if it would shadow a host table.
The contract package stays dependency-free and imports no host code; every new
Protocol method has a default so later additions remain additive. The loader's
pre-1.0 rule requires an exact major.minor match, so extensions written against
0.1 are now refused at startup with an actionable install hint rather than
loading into a host that implements a different surface.
uv.lock records the contract package's new version, so `uv sync --locked` still
resolves on a fresh checkout.
