fix(skills): install for a user keeps its custom-dir setup off the event loop (#5650)
* fix(skills): install for a user keeps its custom-dir setup off the event loop UserScopedSkillStorage.ainstall_skill_from_archive re-implemented the install pipeline and created the per-user custom directory inline, so the await behind POST /api/skills/install blocked the Gateway loop on os.mkdir. The base class offloads every filesystem phase around its LLM scan — and says so — but the override's setup step sat above that comment and escaped it, and the existing blocking-IO anchor drove only the host-scoped class. Offload the mkdir through the same worker thread and anchor the override itself under the strict Blockbuster gate. * test(blocking-io): pin per-user staging of supporting skill files Review follow-up on #5650: the user-scoped anchor asserted only the staged SKILL.md, so a regression that mis-stages the references/ tree under the per-user root would pass both anchors. Assert the supporting file against the per-user layout as well, mirroring the host-scoped twin. |

feat(memory): add opt-in relevance-aware retrieval ranking (#5251)
* feat(memory): add opt-in relevance-aware retrieval ranking Add a deterministic, network-free lexical relevance strategy for DeerMem (issue #4495): memory_search ranks every fact in scope by idf-weighted token overlap combined with confidence, with optional greedy-MMR diversity against near-duplicate facts; prompt injection ranks facts against the current-turn query threaded from DynamicContextMiddleware through the new optional `query` keyword on MemoryManager.get_context/aget_context. Defaults preserve the legacy confidence-only behavior exactly; no prompt, storage-format, or vector/embedding-dependency changes. Refs #4495 Signed-off-by: pwd11 <fvdsrc@163.com> * fix(memory): bound relevance retrieval and apply review feedback Bound tokenization and index shared stems, preserve mixed CJK tokens, warm jieba, and align missing confidence with legacy injection. Cache MMR token sets and stop selection at result or injection budgets. Document retrieval-adapter precedence and add regression coverage. Refs #4495.

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(channels): stream-cap and validate WeChat/WeCom inbound media downloads, fixes #5223 (#5225)
* fix(channels): stream-cap and validate WeChat/WeCom inbound media downloads, fixes #5223 * fix(channels): address WeCom APPID, decompression, and log-sanitization review findings (#5223) Round-4 review follow-ups on the inbound-media download cap: - The COS bucket numeric suffix is the owner's Tencent Cloud APPID and bucket names are user-chosen, so any Tencent Cloud account could register a matching ww-aibot-img-* bucket and pass the shape gate. The built-in rule now admits only the APPID observed in Tencent's published aibot callback examples (1258476243), across regions; any other account (including a future WeCom rotation) goes through channels.wecom.allowed_media_hosts. - aiter_bytes() transparently decodes Content-Encoding, and the decoder allocates the full decompressed body before the byte cap sees a chunk (an ~8 KB gzip wire chunk decoding to 8 MiB reproduces it). Both URL readers now send Accept-Encoding: identity, refuse a response with a residual Content-Encoding before reading, and iterate aiter_raw(). - httpx.HTTPStatusError formats the signed URL (path + query credentials) into its message, so _ingest_inbound_files' reader-failure branch logs a sanitized summary (class + status) instead of logger.exception, and the WeChat extract paths catch httpx.HTTPError so the polling loop's per-message logger.exception can never render a media URL. Every change ships with a red/green regression: the reviewer's 403 mock-transport repro asserted against caplog.text (fully formatted logs), the reviewer's different-APPID bucket host, and gzip bombs driven through real httpx mock transports in both readers. Docs (channels AGENTS.md, README, config.example.yaml) updated for the APPID pinning and encoding gate. * docs(channels): document why the inbound-media cap is 50 MB, not WeCom's 100 MB ceiling * fix(logging): redact URLs in httpx request logs down to scheme + host, fixes #5223 httpx emits 'HTTP Request: GET <full URL>' at the Gateway's INFO level before any response handling runs, so even successful signed-media downloads leaked their credentials. HttpxUrlQueryRedactionFilter (installed by configure_logging) rewrites those records in place — path and query become /<redacted>, method/status/duration observability is preserved — which also keeps Telegram's token-bearing Bot API paths out of the logs. Reader-level regression tests run at production INFO level with a real MockTransport, success paths included. * fix(logging): blank userinfo credentials in httpx request-log redaction * fix(logging): redact authority-only URLs and cover urllib3 redirect logs Two follow-ups from the review plus one extrapolation of the same class: - rest is now optional in _URL_REDACT_RE, so an authority-only URL (scheme://user:pass@host, no path) is rewritten too — userinfo had nowhere else to hide and previously passed through verbatim. A bare credential-free origin still passes through unchanged. - Renamed to UrlRedactionFilter / install_url_log_redaction and attached to the urllib3 logger as well: urllib3 logs 'Redirecting <url> -> <url>' at INFO with full URLs on both sides, the same leak class on a different library logger. No gateway path today both uses requests and redirects a signed URL, but the class stays closed instead of dormant. - Unit tests now build records with the real httpx 0.28.1 format string ('HTTP Request: %s %s "%s %d %s"', 5 args) and httpx.URL args, per the nit, instead of a synthetic shape httpx never emits. * fix(logging): install URL redaction at handler level so propagated records are covered A logging.Filter on a logger only runs for records emitted through that exact logger — child loggers neither inherit it nor trigger it on propagation — so the previous attachment to the bare urllib3 logger was dead code: urllib3 emits Redirecting via urllib3.poolmanager at INFO and urllib3.connectionpool at DEBUG. The filter is now attached to every root handler (mirroring _install_trace_filter, which already iterates root handlers; handler-level filters see propagated records) in addition to the httpx logger (httpx emits via the bare name, and emission-point coverage survives handlers added later). The wiring is pinned by tests that emit through the real urllib3 child loggers — a mutation removing the handler-level install turns them red. Comments, docstrings, and AGENTS.md now state the actual emitter names and levels. * fix(logging): redact urllib3 DEBUG request lines, whose split shape evaded the URL regex urllib3's per-request line (connectionpool.py:545 on 2.7.0) renders as `scheme://host:port "METHOD /path?query HTTP/x.x" status len` — the authority ends at a space so _URL_REDACT_RE's bare-origin early return applies, and the quoted origin-form target has no scheme, so neither half was rewritten. UrlRedactionFilter now runs a dedicated request-line shape first (collapsing the target to /<redacted>, keeping scheme+host+method+ version), then the absolute-URL pass. Regressions pin the exact format string both at unit level and through the real urllib3.connectionpool DEBUG emit path; AGENTS.md wording now names both covered DEBUG shapes. * fix(logging): redact urllib3 retry lines and linearize scheme scanning Closes the two open review threads on the inbound-media log hardening: Retry/redirect targets: urllib3 logs the request target with no scheme in five shapes the generic absolute-URL pass cannot see - `Retry: <target>` (connectionpool.py:954 DEBUG), `Incremented Retry for (url='<target>')` (util/retry.py:545 DEBUG, absolute on the redirect path), `Retrying (...) after connection broken by '<err>': <target>` (connectionpool.py:869 WARNING, above the INFO root), and origin-form halves of both Redirecting emitters (poolmanager.py:500 INFO / connectionpool.py:922 DEBUG). Each gets a rewrite anchored to the exact urllib3 format, collapsing the target to /<redacted>; the generic pass's rest now stops at quote characters so a quoted URL keeps its closing punctuation (previously the absolute-form increment line was mangled), and the request-line method class accepts any case. The emitter enumeration in channels AGENTS.md is closed against the installed urllib3 2.7.0 source. Quadratic scanning: both scheme-bearing patterns start with a character class, so re.sub retried every suffix of a long token - 64K paths cost ~1.8s and URL-free 64K error bodies ~3.1s per record, synchronously in every root handler. The two passes are now driven from literal "://" occurrences: _scheme_starts walks back over the scheme charset to each run's first letter and the pattern is attempted only there, reproducing re.sub's leftmost-non-overlapping result in linear time (256K path: 5.6ms; worst adversarial shapes <= 28ms). Long-input regressions pin the URL-bearing and URL-free cases with mutation-verified bounds, plus nested-scheme and digit-headed-run equivalence cases. Validation: tests/test_logging_config.py 12/12; scheme-pass equivalence against the old re.sub pipeline verified by two independent 30k+ case fuzz runs; full-suite A/B against HEAD shows zero tests that pass on HEAD and fail with this diff. * fix(logging): boundary-aware quote stops and whole-message Redirecting anchor Two follow-ups on the urllib3 redaction shapes: Embedded quotes: `rest` treated ANY quote as a closing mark, so a URL with an apostrophe in the path kept everything after it verbatim (`https://h/path'quoted'?token=Q` rendered the credential suffix in full) while the class docstring claimed path/query/fragment are replaced. A quote now closes `rest` only at a boundary - followed by whitespace, a closing parenthesis, or end of string - so urllib3's Incremented Retry (url='...') scaffolding keeps its ') closer while an embedded quote stays consumed. The increment line's url capture gets the same rule narrowed to its fixed ')' closer. Redirecting anchoring: the origin-half pass matched `(? <=-> )/path` as a substring, and an `-> /path` arrow is not urllib3-owned shape - the sandbox provider's actionable mount error (`sandbox.mounts entry <host> -> /mnt/knowledge ignored: ...`) had its container path rewritten to /<redacted>, failing test_setup_path_mappings_logs_actionable_error_for_missing_host_path on CI (backend-unit-tests shard 3). The pass is now anchored to the whole `Redirecting <t> -> <t>` message, which is exactly urllib3's record; origin slots collapse, absolute slots stay for the generic pass. Regression tests pin the embedded-quote shapes and the sandbox error's byte-for-byte passthrough; both mutations verified red. Validation: tests/test_logging_config.py 14/14; the CI-failing sandbox test green locally; every test file asserting redaction/arrow log content passes (attachments, support bundle, run metadata, skill secrets, ragflow, skillscan, sandbox provider); full offline backend suite 14084 passed / 164 failed with the failure set matching this machine's documented Windows-environment baseline (NTFS chmod/symlink, docker/lark/langfuse absences) - no failure involves redaction output. * fix(logging): redact redirects with spaced locations * fix(logging): grammar-complete Redirecting anchor; neutral WeChat guard labels Round-13 P3 (Redirecting anchor strictness): the whole-message anchor kept the ^Redirecting prefix (the urllib3-owned literal that stops the sandbox false positive) but required BOTH slots whitespace-free, so a Location header with an interior space voided the pass and leaked the origin-form request target in the first slot - redirect_location is the raw header string and interior spaces are legal field syntax. The tail is now loose (\S.*$) and the first slot gets the same grammar treatment (\S.*?): the recursive urlopen frame passes the previous raw Location as its url, so t1 can carry interior spaces too, lazy-split at the first arrow the way the line is constructed. A space-carrying slot collapses whole when it starts with /; the sandbox mount error keeps passing through untouched. Round-14 nit (None conflation): _download_cdn_bytes returns None for two reasons (in-flight cap abort, Content-Encoding refusal) but both image and file callers labeled it "exceeds size limit (N bytes)" - contradicting the accurate encoding line right above it, and reporting the plaintext limit for a ciphertext-cap decision. Callers now log a neutral "skipped by download guard" line (the manager reader callers' shape); the accurate reason stays inside the download function. The same sweep also logs _stage_downloaded_file's silent None (no state dir configured), which made an attachment vanish with no log line at all. Also anchors the emitter-enumeration closure to its urllib3 version: the closure reopens if an upgrade changes these format strings, so the comment now says so explicitly. Validation: logging 15/15 and attachments 60/62 (the two pre-existing Windows symlink-privilege failures documented in the PR body); three mutations verified red (old wording, strict t1, silent staging None); ruff clean. Full offline suite run before push (per round-11 lesson). --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

test(skills): skip the skill-export capture suite where fd-based walking is unavailable (#5372)
* test(skills): skip the skill-export capture suite where fd-based walking is unavailable export._capture intentionally rejects every export with 422 skill_export_unsupported on platforms without os.O_NOFOLLOW and dir_fd directory walking (Windows), so the 40 capture-dependent tests in test_skill_export.py and test_gateway_skill_export.py fail there. Add a requires_safe_capture mark mirroring the production feature guard and apply it to those tests; the 21 tests that only exercise the zip installer, export lock, or router plumbing keep running. * test(skills): share requires_safe_capture and cover the blocking-io export suite Move the mirror of export._capture's platform guard into tests/support/skill_export_platform.py so the per-file copies cannot drift, and apply it to blocking_io/test_skill_export.py::test_export_worker_and_response_are_off_loop, which drives the real exporter and hits the same 422 skill_export_unsupported guard on Windows (the blocking-io suite is excluded from the default make test run). --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.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(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> |

fix(agents): make the injected current-date timezone configurable (#5154)
* fix(agents): make the injected current-date timezone configurable ## Why The date reminder injected into the lead and subagent prompts (DynamicContextMiddleware / SubagentDateContextMiddleware) was formatted with the server's local wall clock. DeerFlow containers default to UTC, so a user in Asia/Shanghai chatting in the 00:00-08:00 window was told that 'today' is the previous day - the model then reasons, plans, and date-stamps against the wrong day. ## What changed - _format_current_date() now reads the optional DEER_FLOW_DATE_TIMEZONE env var (IANA name, e.g. Asia/Shanghai) and renders the date in that zone. - Unset = unchanged server-local behavior; invalid names log a warning and fall back to server-local. - Documented the knob in config.example.yaml, the module docstring, and the DynamicContext entry in agents/middlewares/AGENTS.md. ## Surface area - [x] Agents / LangGraph - prompt-layer date context only; message shape and midnight-update behavior unchanged - [ ] Frontend UI / Backend API / Sandbox / Skills / Dependencies - [x] Default behavior change (opt-in via env var - no behavior change unless set) ## Bug fix verification - New tests: test_format_current_date_honors_configured_timezone (UTC 20:30 -> 2026-09-03 in Asia/Shanghai), test_format_current_date_defaults_to_server_local_without_env, test_format_current_date_invalid_timezone_falls_back. - Existing mocked-datetime tests pass unchanged (no env -> datetime.now() path). ## Validation - cd backend && python -m pytest tests/test_dynamic_context_middleware.py: 31 passed. - blocking_io/test_dynamic_context_middleware.py: 2 pre-existing abefore_agent failures reproduce identically on clean main (blockbuster os.listdir detection on this host); the other 2 pass. - ruff format + ruff check clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** analysis, implementation, and regression tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(agents): avoid passing tz to datetime.now when no timezone is configured CI (backend-unit-tests shard 2) failed in test_tool_error_handling_middleware.py::test_subagent_chain_injects_date_without_memory_and_coalesces_for_strict_provider because its _FrozenDateTime.now() subclass override accepts no arguments, while _format_current_date() called datetime.now(None) even when DEER_FLOW_DATE_TIMEZONE was unset. - _format_current_date() now calls datetime.now() with no arguments unless a timezone is actually configured, preserving the exact legacy call shape for every datetime-subclass test fake. - The configured-zone path still calls datetime.now(tz) and converts via astimezone(tz). - Updated the no-env unit test to assert datetime.now() is called without arguments. Validation: python -m pytest tests/test_dynamic_context_middleware.py + the previously failing strict-provider test: 32 passed. ruff clean. * fix(agents): declare the effective current-date timezone in the assembly descriptor ## Why Maintainer review on the DEER_FLOW_DATE_TIMEZONE change (#5154): the knob is prompt-affecting, yet both DynamicContextMiddleware and SubagentDateContextMiddleware were invisible to the agent assembly descriptor - describe_middleware() fell back to {"probed": true} for unset, UTC, and Asia/Shanghai alike, so deployments that inject different dates shared one assembly fingerprint and release observers could not distinguish or audit the behavior change. ## What changed - Both middlewares now implement release_policy_parameters() -> dict[str, object], declaring {"current_date_timezone": <name>} as required by the module's middleware self-description contract. - The declared value is the normalized effective zone: a configured, valid DEER_FLOW_DATE_TIMEZONE is reported by its IANA key (ZoneInfo.key); otherwise the server-local zone is resolved to its IANA key when the platform exposes one and to its tzname label otherwise (fixed-offset hosts), with "UTC" as the final fallback. - Added both middlewares to _MIDDLEWARE_DECLARATIONS in backend/tests/test_middleware_release_policy.py so the existence check and the construct-and-canonical-hash check cover them. ## Verification - New tests: test_date_middlewares_declare_configured_timezone (Asia/Shanghai), test_date_middlewares_declare_utc_timezone, plus resolved-server-local assertions for the unset and invalid-env paths; both middlewares agree in every case. - cd backend && python -m pytest tests/test_dynamic_context_middleware.py tests/test_middleware_release_policy.py: 70 passed. - Regression spot-check: tests/test_agent_assembly_descriptor.py, tests/test_tool_error_handling_middleware.py, tests/test_system_message_coalescing_middleware.py: 102 passed. - ruff check + ruff format clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** analysis, implementation, and regression tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(agents): stabilize the declared date timezone and simplify the formatting path ## Why Follow-up review on #5154 (willem-bd). The release-policy declaration added in 884cec4b resolved the observability gap but pinned far less identity than its docstrings claimed, and the formatting path carried a production no-op. ## What changed - The declared label is now stable and unambiguous: a configured, valid DEER_FLOW_DATE_TIMEZONE is reported by its IANA key; without one, the server-local zone is resolved to a real IANA key from the TZ env var or the /etc/localtime symlink (Linux/macOS); when no key is recoverable (Windows, stripped containers) the declaration falls back to a stable `server-local(+-HH:MM)` sentinel carrying the current UTC offset. It never reports a bare abbreviation - datetime.now().astimezone() yields only a fixed-offset timezone whose tzname (e.g. CST, EST/EDT, CET/CEST) is ambiguous or DST-churns, which the assembly descriptor docstring says must not happen. - Dropped the redundant astimezone(tz) in _format_current_date(): datetime.now(tz) already returns the instant expressed in tz. The configured-zone test now fakes datetime.now(tz) semantics (the fixed instant converted into the requested zone) instead of relying on that conversion. - Documented why the knob is an env var, not a config-schema field: it is read at runtime by both date-context middlewares so an operator can point a container at another zone without mounting a config.yaml (module docstring + config.example.yaml note). - AGENTS.md: fixed the glued DynamicContext sentence (missing separator). - Added tzdata>=2025.1 to the harness runtime dependencies (with uv.lock) so ZoneInfo works on stripped containers / Windows without an OS zone database. ## Verification - New tests: test_server_local_timezone_name_reads_tz_env, test_effective_timezone_sentinel_uses_offset_when_local_zone_is_not_resolvable; reworked test_format_current_date_honors_configured_timezone to exercise the real datetime.now(tz) path. - cd backend && python -m pytest tests/test_dynamic_context_middleware.py tests/test_middleware_release_policy.py tests/test_agent_assembly_descriptor.py tests/test_tool_error_handling_middleware.py: 140 passed. - ruff check + ruff format clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** analysis, implementation, and regression tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(agents): offload subagent date injection off the event loop ## Why Follow-up review on #5154 (willem-bd, P2): SubagentDateContextMiddleware.abefore_agent() called _inject() directly, so enabling DEER_FLOW_DATE_TIMEZONE could synchronously read the OS timezone database (or the tzdata wheel) on a cold cache - filesystem work on the async subagent execution path whenever no assembly observer resolved the zone first. ## What changed - SubagentDateContextMiddleware.abefore_agent() now offloads the injection via asyncio.to_thread with the same bounded timeout DynamicContextMiddleware uses (issue #3402); on timeout it logs and skips the date update for that run instead of blocking the loop. - Narrowed the exception handling in _date_timezone() and the TZ-env branch of _server_local_timezone_name() to configuration-shaped failures (ZoneInfoNotFoundError / ValueError / OSError). Previously a blanket `except Exception` also swallowed BlockingError raised by the blocking-I/O regression gate, mislabeling a loop-blocking call as an invalid timezone and silently degrading to server-local - which made the new regression anchor useless. Other exceptions now propagate. ## Verification - New blocking-I/O regression anchor (backend/tests/blocking_io/test_subagent_date_context_middleware.py): drives a real create_agent graph under the strict Blockbuster gate with the knob enabled and asserts the date reminder is injected. Verified it fails (BlockingError) when the offload is reverted and passes with it in place. - python -m pytest tests/blocking_io/test_subagent_date_context_middleware.py: 1 passed. The two pre-existing os.listdir failures in tests/blocking_io/test_dynamic_context_middleware.py reproduce unchanged on this host (same as clean main). - python -m pytest tests/test_dynamic_context_middleware.py tests/test_middleware_release_policy.py tests/test_tool_error_handling_middleware.py tests/test_agent_assembly_descriptor.py: 139 passed; the single ToolReceiptMiddleware-ordering failure reproduces with the change stashed (local extensions registry, unrelated to this PR). - ruff check + ruff format clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** analysis, implementation, and regression tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. * fix(agents): read the direct /etc/localtime symlink target for the zone key ## Why Follow-up review on #5154 (willem-bd, P2): on macOS, /etc/localtime commonly points to /var/db/timezone/zoneinfo/<zone>, but Path.resolve() follows that directory's own symlink and yields a versioned path such as /private/var/db/timezone/tz/2026c.1.0/zoneinfo/Asia/Shanghai, which matched no configured prefix. The server-local resolution then returned None and the assembly descriptor fell back to a server-local(+HH:MM) sentinel even though the IANA key was available - conflating zones that share an offset and making DST-based fingerprints unstable. ## What changed - _server_local_timezone_name() now reads the direct symlink target via os.readlink("/etc/localtime") instead of Path.resolve(), so macOS' unversioned zoneinfo path is seen as-is and its IANA key is preserved. - The zone key is taken from whatever follows the last "/zoneinfo/" segment, which also handles Apple's canonical versioned path when a direct target already carries it, and relative targets are normalized against /etc. - Removed the now-unused Path import and the fixed zoneinfo prefix tuple. ## Verification - New tests: test_server_local_timezone_name_reads_direct_macos_symlink_target, test_server_local_timezone_name_reads_apple_versioned_symlink_target, and test_server_local_timezone_name_normalizes_relative_symlink_target. - python -m pytest tests/test_dynamic_context_middleware.py tests/test_middleware_release_policy.py tests/test_agent_assembly_descriptor.py: 105 passed (75 after re-running the first two on the merged main). The blocking subagent anchor still passes; the two pre-existing os.listdir blocking failures on this host are unchanged. - ruff check + ruff format clean. ## AI assistance **Tool(s) used:** Codex (coding agent) **How you used it:** analysis, implementation, and regression tests produced with AI assistance; reviewed before commit. - [ ] I've read and understand every line of this change and take responsibility for it — it's not unreviewed AI output. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

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> |

feat(harness): deterministic acceptance checklist for subagent delegations (RFC #4651, layer 2) (#5109)
* feat(harness): deterministic acceptance checklist for subagent delegations (RFC #4651, layer 2) PR4 of RFC #4651: check lead-supplied acceptance_criteria in code when a subagent completes, so objectively checkable requirements can never be silently passed by a self-report. - subagents/acceptance_checks.py: deterministic leaf families — file:<path> exists|non-empty and file_written:<path> read through read_current_file_content scoped to the shared thread workspace; the read uses the sandbox-native virtual path form (the local read validator and provider mount tables resolve /mnt/user-data/... paths, not host paths); the scope decision canonicalizes with realpath on the local sandbox so workspace symlinks cannot escape into uploads; a remote provider's "Error: ..." return string is normalized to a failed check (provider-typed via is_local_sandbox); a UnicodeDecodeError marks a binary deliverable as existing and non-empty; out-of-scope paths degrade to UNVERIFIED. tests_passed:<command> anchors to a matching recorded bash execution with status=success and a test-summary shape; matching is shell-structure aware with control-flow attribution (span must end at the last segment with provable execution), negating-option values are ineligible evidence and a target negated anywhere in the command degrades the match, extra flags must be selection-preserving, extra positionals widen only after a path-scoped criterion, truncated commands degrade via command_truncated, the summary shape is read only from output attributable to the matched segment (preceding segments provably silent by invocation form), and pass shapes require a nonzero passed count. Criterion text is neutralized with neutralize_untrusted_tags before storage/rendering. Anything else renders UNVERIFIED, never silently passed. - executor: accumulate bounded bash command/output evidence per streamed chunk (merged by tool_call_id, newest-capped) so subagent summarization compacting earlier messages cannot erase a recorded execution; the recorded status is the actual shell exit status parsed from the output's exit marker (signed codes included; the remote Command exited with code N form is accepted only as the whole trimmed output), falling back to deerflow_tool_meta only when no marker exists. - sandbox providers: e2b/opensandbox/tenki/boxlite append the LocalSandbox-style "Exit Code: N" marker on nonzero exit even with non-empty output; aio propagates the SDK's structured exit_code on both exec paths the same way; local timeouts append Exit Code: 124; and _truncate_bash_output always preserves a trailing exit marker (signed included) inside its budget, with a 32-char floor raising any smaller configured limit, so the actual shell outcome always survives in the output text. - task_tool: run the checklist offloaded (asyncio.to_thread) on the completed branch, failure-isolated; stamp the verdict into result metadata and render the per-criterion section into the model-visible result text. - status contract: additive subagent_acceptance_verdict transport with read-side structural validation. - delegation ledger: entry carries the verdict and renders a compact acceptance segment; gateway strips caller-forged verdicts from both ledger entries and message metadata, like the citation verdict. - blocking-IO anchor pins the offload (teeth proven red->green); leaf read errors catch only OSError/SandboxError so unexpected errors reach the task-tool-level isolation instead of being mislabeled. * fix(harness): close acceptance evidence gaps from review (RFC #4651 PR4) - negating options: overlap with a matched criterion target is now checked by path/nodeid prefix, not exact token equality — excluding a sub-path of the criterion's selection (pytest tests --deselect tests/unit/test_auth.py) degrades to UNVERIFIED instead of holds - output attribution: any redirection token in the matched final segment makes the recorded tail non-attributable (> / >> / 2> are word characters to the parser, so redirection was invisible to the matcher) - silent-source allowlist narrowed from any *activate suffix to the */bin/activate shape - status_contract docstring: restore the shared-fixture sentence and note subagent_acceptance_verdict is deliberately outside the fixture - executor: update_bash_executions publishes [] (stream carried no bash-family calls) instead of collapsing it into None, mirroring update_tool_receipts * fix(harness): close acceptance residual gaps from re-review (RFC #4651 PR4) - tests_passed: add error outcomes to the fail shapes — "4 passed, 1 error" and pytest's "ERROR <nodeid>" short summary no longer satisfy the pass shape when the exit status is swallowed (|| true) or absent; zero-error counts stay clean. - file leaves: bound the deliverable read — a "wc -c" shell size probe answers files above 50k bytes without loading ~2x their size, honoring the host-bash kill switch and falling back to the full read on any non-integer rendering, so verdicts never get less sound. - executor: record the exit marker text as status_marker on harvested bash evidence; the leaf detail now reports the marker actually seen instead of asserting a failure indistinguishable from the command's own trailing text. - extend the blocking-IO anchor to drive the probe branch inside the offload; teeth re-verified red->green. * fix(harness): close acceptance forgery and bound gaps from P2 re-review (RFC #4651 PR4) - file leaves: never read unbounded — size is established first (os.stat on the validated local host path, so the host-bash-disabled configuration needs no shell; a guarded wc -c on remote providers that renders missing/unreadable in its own words). Above the 50k cap the leaf answers from the size alone, at/below it the full read runs, and an unestablishable size degrades to UNVERIFIED instead of an unlimited fallback read. - output attribution: source/. prefixes are never provably silent — a crafted */bin/activate path shape says nothing about what the script prints, so sourced segments can no longer lend a passing summary. - executable identity: an explicitly path-spelled criterion now requires the same normalized executable path; the basename rule stays only for deliberately bare criterion commands. * fix(harness): run acceptance size probe outside subagent-controlled state (RFC #4651 PR4) - remote probe no longer runs in the sandbox's persistent shell: a fresh env -i /bin/sh with absolute-path stat/realpath (poisoned functions, aliases, PATH, exported functions, IFS, locale cannot steer it), plus a marker env routing AIO onto a fresh per-call bash.exec session. - metadata-only: stat never opens content, so a FIFO deliverable cannot block the parent for the provider's idle timeout; non-regular files (fifo/dir/symlink) degrade to UNVERIFIED. - containment canonicalized against the literal mount root: a final-component symlink or a swapped parent directory (root included) cannot redirect the check outside shared storage; unprovable layouts degrade to UNVERIFIED. * fix(harness): canonicalize probe containment against the canonical mount root (RFC #4651 PR4) Literal-root equality made every remote file leaf permanently UNVERIFIED on e2b and Tenki, which realize /mnt/user-data as a symlink to the home dir by default (e2b bootstrap 'sudo ln -sfn', Tenki best-effort symlink). Containment now compares the file's realpath against the mount root's realpath — exactly what the provider's own read path resolves, so probe and read-back stay consistent; final-component symlinks stay rejected by the non-dereferencing stat, and an intermediate dir-link escape under a sane root still lands ESCAPED. The inner script is a module constant and the suite now executes the composed probe for real against on-disk layouts (real dir, symlinked prefix, final symlink, fifo, missing, dir-link escape), which the canned-output stub could not see. * fix(harness): close bare-criterion negation and CDPATH summary channels (RFC #4651 PR4) - matching: a criterion with no positional selection target (bare pytest, make test) stands for the runner's default selection, so ANY negating option (--ignore/--deselect/...) makes the recorded run a different selection — unprovable. The overlap guard only sees consumed criterion tokens, which a bare criterion does not have; scoped criteria keep the unrelated-exclusion behavior. - attribution: cd is no longer blanket-silent — CDPATH makes cd print the resolved (subagent-chosen) destination and the pass shapes match as substrings, so one mkdir 'all tests passed' plus an export minted a pass for any quiet command. A cd argument or CDPATH= value (export or leading assignment) carrying any summary shape makes the segment non-silent; shape-free cd dir wrappers keep matching. - docs: _truncate_bash_output states the effective 32-char floor (the guarantee previously read as an unconditional max_chars bound). * fix(harness): close env-assignment and expansion channels in acceptance matching (RFC #4651 PR4) Self-audit in the shape of the last review rounds — channels the matcher classified as accounted-for that can change what runs, narrow the selection, or lend the summary text: - env assignments are no longer blanket-stripped: only an allowlist of inert display/CI knobs (CI, NO_COLOR, PY_COLORS, ...) may prefix a matched span, and a non-allowlisted assignment in any preceding segment (pure-assignment or export NAME=) is state pollution — PATH redirects the executable, LD_PRELOAD/PYTHONPATH/NODE_OPTIONS inject code, PYTEST_ADDOPTS/GOFLAGS/MAKEFILES inject selection-changing inputs, BASH_ENV runs arbitrary shell startup. All degrade to unprovable. - runtime expansions: any span token carrying /$( )/backticks, any negating-option value carrying an expansion or glob (unknown excluded set), and any extra executed token carrying glob metacharacters (crafted option-looking filenames narrow invisibly) are unprovable. Criterion-side globs stay self-consistent (literal match). - cd: an argument carrying a runtime expansion or glob is non-silent (unknown destination, unknown print); CDPATH= assignments are now handled as state pollution at the match layer, subsuming the value-shape special case. * fix(harness): persistent-shell evidence, exact env sets, option-arity scoping (RFC #4651 PR4) - tests_passed: on a persistent-shell provider (new Sandbox.persistent_shell_sessions capability, set by AioSandbox) every leaf degrades to UNVERIFIED — any earlier call in the shared session could have mutated the state the clean-looking run executed in, and only a fresh controlled session (RFC section 6 verifier) can prove otherwise. The flag is read from the provider registry without acquiring a sandbox. - env assignments: the allowlist is gone — no variable is provably inert across repositories (CI/DEBUG are routinely read by tests). The span's assignment prefix must equal the criterion's exactly (values included, order-insensitive); any assignment or export NAME= in a preceding segment is state pollution. - scoping: positional targets are now read by option arity, so a path embedded in an option (--basetemp=/tmp/p, --junitxml=/tmp/r.xml) never counts as a selection target and an extra positional after such a criterion narrows the default selection it denotes. * fix(harness): stamp shell provenance at harvest, close export/unset and arity gaps (RFC #4651 PR4) * fix(harness): split physical newlines as shell separators in acceptance matching (RFC #4651 PR4) * fix(harness): scope cd wrappers to thread data roots, pin accepted boundaries (RFC #4651 PR4) * fix(harness): preserve criterion connectors, prove file_written readable, fail-closed shell capability (RFC #4651 PR4) * fix(harness): compare only the connector prefix, tolerate trailing criterion semicolons (RFC #4651 PR4) * fix(harness): preserve continuation-line operators, keep ./-spelled executable identity (RFC #4651 PR4) * fix(harness): render criteria single-line so a multiline criterion cannot inject a forged checklist line (RFC #4651 PR4) * fix(harness): reject parent-traversal executable tokens in acceptance matching (RFC #4651 PR4) * fix(harness): reject parent-traversal negated values in acceptance matching (RFC #4651 PR4) |

feat(sandbox): share sandbox identity derivation and acquire serialization (#4741) (#5089)
* feat(sandbox): share sandbox identity derivation and acquire serialization (#4741) Remote providers (AIO, E2B, BoxLite, Tenki, OpenSandbox) each inlined the same sha256(user:thread)[:16] sandbox-id expression and kept per-scope lock dicts that grew unboundedly until shutdown. This extracts both mechanisms into shared components without changing provider lifecycle, ids, capacity semantics, or public tool behavior: - sandbox/identity.py: keyword-only derive_sandbox_scope_token (byte-pinned compatibility contract) + is_sandbox_scope_token; per-provider golden vectors pin current behavior including BoxLite's raw-None quirk and each provider's private user_id resolution. - sandbox/acquire_serialization.py: AcquireSerializer — per-key lock table with holder/waiter refcount reclamation, bounded dedicated executor (async waits off both the event loop and the default executor), worker-owned cancellation cleanup (no event-loop callback dependency), idempotent close(). - Each provider adopts both components; AIO/E2B key by (user_id, thread_id) with acquire and (E2B) release serialized; BoxLite/Tenki/OpenSandbox key by derived sandbox id and offload the whole sync acquire to the serializer's executor so a cancelled awaiter cannot overlap a retried same-scope body (leaked-remote-VM regression caught in review). - thread_id=None acquires stay unserialized; provider shutdown()/reset() close the serializer; E2B capacity/ledger/reconciliation and AIO ownership/flock machinery untouched. - blocking-IO anchor proves contended OpenSandbox acquire_async stays off the event loop (teeth verified red/green); AGENTS.md documents the shared components. * refactor(sandbox): address review on acquire serialization (#5089) - Replace unreachable checkin branch with an assertion: run() returns False only after abandon(), which the except handler always re-raises; the old _checkin would have double-decremented the refcount. - Document the task.cancelling() == 0 assumption in hold_async. - Drop unused thread_id/user_id kwargs from BoxLite and Tenki _acquire_scope_locked (OpenSandbox still forwards them). * fix(sandbox): preserve request ContextVars in acquire executor bridge (#5089) loop.run_in_executor() does not copy contextvars, unlike the inherited SandboxProvider.acquire_async() which used asyncio.to_thread(). The BoxLite/OpenSandbox/Tenki acquire_async bridges introduced in this PR therefore dropped the request trace id (logged as trace_id=-). Add AcquireSerializer.run_on_executor(), which copies the calling context and runs the callable through ctx.run, and route all three providers through it. Add regression tests binding request_trace_context and verifying the worker thread observes it. |

feat(memory): add Honcho backend (user-model memory provider) (#4730)
* feat(memory): honcho backend config parsing Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(memory): honcho v3 http client Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(memory): honcho memory manager (workspace-per-user, fail-closed identity, async offload) - HonchoMemoryManager implements the MemoryManager contract (add/get_context/ search/get_memory/shutdown_flush + aadd/aget_context/asearch offloaded via asyncio.to_thread), signatures verified against manager.py's tier-1/tier-2/ async abstracts. - Workspace resolution: workspace_overrides[user_id] else workspace_prefix + sanitize_id(user_id); missing/empty user_id fails closed (no-op write, empty read) rather than falling back to a shared workspace. User peer: user_peer_overrides[user_id] else sanitize_id(user_id). - get_context self-truncates to max_injection_chars and raises MemoryManagerError only under failure_policy.read=fail_closed; default is log-and-return "". - Restore backends/honcho/__init__.py to the noop direct-import convention (MANAGER_CLASS = HonchoMemoryManager) now that honcho_manager.py exists, replacing Task 10's temporary lazy __getattr__ scaffold. - Fix Task 10 deferred docstring minor: sanitize_id docstring now states the grammar allows up to 100 chars while this helper caps at 64. - 19 new tests appended to test_honcho_memory_backend.py (write/read/async/ lifecycle/factory-discovery); 27/27 pass. Verified end-to-end that manager.py's drop-in backend scanner resolves "honcho" with no core edits. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(memory): collision-resistant identity derivation, exception containment, passive-writes flag Task review findings (2 Critical + 1 Important), all fixed in the same worktree: - CRITICAL (cross-user bleed): sanitize_id is lossy -- "user.name@example.com" and "user-name@example.com" both sanitized to the same string, merging two users' memory into one workspace/peer. Add _stable_id() (sanitize_id output + 8-hex-char SHA-256 suffix of the raw id) and use it on the default (non-override) path in _workspace/_user_peer; workspace_overrides / user_peer_overrides still match on the raw key, unchanged. The hash suffix also guarantees a non-empty result for a raw id that sanitizes to "" (e.g. "!!!"), so _user_peer can no longer return "". Documented in the manager's isolation docstring. - CRITICAL (exception containment): client.py's _post() called response.json() outside the try block, so a 200 with a non-JSON body raised a bare JSONDecodeError that would escape add() with no upstream handler. Wrap the parse and raise HonchoRequestError (mirrors Mem0Client._request). Broadened the manager's four boundary excepts from `except HonchoRequestError` to `except Exception` (mirrors openviking_manager.py's broad-guard precedent), with `except MemoryManagerError: raise` first so a contract error is never swallowed or double-wrapped. - IMPORTANT: added requires_passive_writes_in_tool_mode: ClassVar[bool] = True -- Honcho's only write path is passive add() (no fact CRUD hooks), so tool mode must keep MemoryMiddleware writes flowing to the deriver. Mirrors mem0_manager.py's identical flag/rationale. Minors addressed: get_memory(user_id=None) empty-shape-with-no-calls test; empty-string user_id tests for add()/get_context(); dedicated collision test proving two colliding raw ids resolve to different workspaces/peers. 10 new tests (37/37 total pass); RED verified by stashing only the implementation files (tests import the not-yet-existing _stable_id, so the whole module fails to collect) before restoring the fix. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(memory): blocking-io anchor for honcho backend; docs + config example - Adds test_honcho_memory_backend.py in tests/blocking_io/ with fake-client blocking IO - Mirrors openviking anchor structure and conftest conventions - Updates backends/README.md with honcho row and config keys section - Updates config.example.yaml with honcho commented block - Updates backend/AGENTS.md with honcho memory backend bullet - Documents workspace resolution (prefix + collision-resistant sanitized id) - Documents tool mode passive write retention via MemoryMiddleware - Documents async entrypoint offloading via asyncio.to_thread - Documents fail_closed vs fail_open recall failure policy Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(memory): wire close() to shutdown hook; correct honcho README defaults and tool-mode note - HonchoMemoryManager.close() releases the HTTP client, mirroring mem0_manager.py's pattern and the base MemoryManager.close() shutdown hook. - README: fix workspace_prefix (deerflow-u-), message_char_limit (8000), max_injection_chars (6000), and base_url (default http://localhost:8000, not required) against backends/honcho/config.py; add missing timeout_seconds/connect_timeout_seconds rows; replace the "middleware mode only" claim with wording matching reality (tool mode supported, search implemented, passive writes retained via MemoryMiddleware). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(memory): honor failure_policy.read on all honcho recall paths; review nits Addresses PR #4730 review feedback: - search() and get_memory() now route through a _read_or_fallback policy gate (mem0's pattern), so failure_policy.read: fail_closed raises MemoryManagerError on every recall path as documented; get_context() uses the same helper, preventing future drift. - Session ids use the collision-resistant _stable_id derivation; bare sanitize_id would merge threads like "t.1"/"t-1" into one session. - HonchoClient accepts a transport kwarg (Mem0Client precedent) so tests inject httpx.MockTransport through the constructor. - Config: empty/null workspace/peer override values fail fast at parse time instead of silently falling through to the default derivation. - _UTC_NOW_FIELDS 1-tuple replaced by a plain _UTC_NOW_FORMAT constant. - README: user_peer_overrides row described the wrong target (it overrides the user's own peer, not assistant_peer); document the non-empty constraint on override values. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(memory): qualify honcho isolation claim for shared workspace_overrides The module docstring claimed users cannot see each other's memory by construction, unconditionally. That holds for the default one-workspace-per-user derivation, but a workspace_overrides entry mapping several users to one workspace shares that workspace's search index: search() uses Honcho's workspace-scoped /search (no peer filter), while get_context()/get_memory() stay peer-scoped via working_representation. State the asymmetry in the docstring, the README Workspace Resolution section, and the workspace_overrides table row. Docs-only; no behavior change (review follow-up on #4730).

fix(sandbox): enforce disabled skills in filesystem views (#4178)
* fix(sandbox): project enabled skills into sandbox views * fix(skills): keep projection mutations consistent * fix(skills): fail closed on projection errors * fix(skills): isolate per-scope failures during boot projection rebuild rebuild_all_skill_projections() propagated any exception from the public rebuild or from a single user's rebuild straight out of the gateway lifespan startup, uncaught. A single broken user directory (bad permissions, corrupted _skill_states.json, unreadable content) would therefore abort gateway boot for every user, not just that one - _rebuild_*_locked already fails closed internally (clears the view and re-raises), so the boot loop only needed to stop treating that re-raise as fatal. Each scope's rebuild now fails closed independently and boot continues; a scope left empty by a boot failure self-heals on the next sandbox acquire via ensure_skill_projections(). Also patches deerflow.skills.projection.rebuild_all_skill_projections in the memory-flush lifespan test fixture, matching the two sibling fixtures in the same file — this call is now on the lifespan startup path and the fixture's minimal SimpleNamespace config predates it. * test(skills): update authz test for the projection-aware public toggle _persist_shared_skill_state (introduced earlier in this branch) reads the shared extensions_config.json fresh from disk under the projection lock instead of through the cached get_extensions_config() singleton - that's the whole point of the fix (stale worker caches must not clobber another worker's concurrent update). The name no longer exists on the skills router module, so the test's monkeypatch of it started raising AttributeError instead of exercising the endpoint. The mock storage in this test isn't a real LocalSkillStorage instance, so _persist_shared_skill_state's projection-mutation branch is already skipped (nullcontext) and it falls back to a fresh ExtensionsConfig() for the nonexistent tmp config_path - no replacement monkeypatch needed. * fix(sandbox): make skill projection ensure best-effort in acquire acquire() called _ensure_skills_projection() directly, outside any try/except, in both LocalSandboxProvider and AioSandboxProvider. Every other skill-mount setup path in these providers has always caught exceptions and logged a warning rather than failing sandbox acquire outright (e.g. when config.yaml can't be resolved) - these two new call sites broke that contract, so any projection failure (including simply not having a config.yaml, as in CI's test environment) now failed acquire() itself instead of just leaving skill mounts off. _ensure_skills_projection now catches its own exceptions and returns None; both providers' callers already tolerate that (a None projection skips the skill-specific mounts, matching the existing degrade path) after making _append_public_skill_mapping and the custom/legacy mount block in LocalSandboxProvider explicitly None-safe. Caught by running the full suite with config.yaml removed, matching CI's environment - not caught locally because a real config.yaml was present, masking the failure. * fix(sandbox): make E2B skill projection mounts best-effort _skill_projection_mounts called ensure_skill_projections with no guard, unlike Local/AIO's _ensure_skills_projection. A raise propagated out of _apply_mounts before the configured-mounts loop ran, so a skills projection failure dropped the operator's own configured mounts too - only caught by create()'s outer warning, with nothing applied at all. Swallow here and return an empty mount list on failure, matching the Local/AIO pattern: still fail-closed for skills, but no longer widens the blast radius to unrelated configured mounts. Review feedback from PR #4178. * docs(skills): document projection trade-offs flagged in review - _update_tree_digest: note the metadata-only (not content) hashing trade-off and why runtime writes through this codebase are still covered regardless (rebuild-under-lock + rename always changes inode). - LocalSandboxProvider.acquire: note the acquire-time self-heal cost (cheap on a fresh manifest, ~400ms rebuild under lock on stale/drift). - skill_projection_mutation: drop the no-op except-Exception-then-raise; a raise from the mutation already propagates past the yield with the view left cleared, no explicit re-raise needed. - provisioner README: spell out that hostPath skills volumes require the gateway and K8s node to share DEER_FLOW_HOST_BASE_DIR (single-node or shared storage), and that the custom/legacy volumes' hostPath type Directory (not DirectoryOrCreate) makes a violation of that assumption a visible Pod-creation failure instead of a silent empty mount. Review feedback from PR #4178. * fix(skills): lazily repair user projections * fix(skills): close projection review gaps * fix(skills): refresh user projection enable state * fix(skills): close projection review follow-ups * fix(skills): preserve state across projection writes --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(skills): offload blocking filesystem IO in update_skill and serialize writes (#3565)
* fix(skills): offload update_skill's blocking IO and share the config write lock Re-applied on top of main rather than merged: update_skill has since gained admin gating, user-scoped storage and a PUBLIC vs CUSTOM/LEGACY split, so the offload is applied per path. - PUBLIC: the extensions_config.json read-modify-write (path resolve, snapshot, merge, write, reload) moves to a worker thread via asyncio.to_thread. The payload is built from a snapshot so the cached singleton is never mutated in place while the write is still in flight. - CUSTOM/LEGACY: set_skill_enabled_state is offloaded; the non-user-scoped fallback takes the same shared-file RMW path as PUBLIC. - Both load_skills calls (and storage construction) are offloaded. The RMW lock now lives next to reload_extensions_config as get_extensions_config_write_lock() and is acquired by both the skills router and the MCP router, which performs the same read-modify-write on the same file. Previously each router held its own module-local lock, so once both sides offloaded, a PUT /api/mcp/config could run inside a skill toggle's read->write window and the later write would silently drop the other's change. The lock is keyed by the running event loop rather than being a module-level singleton: asyncio primitives bind to the first loop that awaits them, which makes a plain module-level lock unusable in a process that runs more than one loop. Adds a cross-router regression anchor asserting a skill toggle and an MCP update never overlap inside the RMW (max in-flight 1); it observes 2 when the routers use separate locks. * fix(config): own the extensions_config RMW lock from the worker thread An asyncio.Lock held around `await asyncio.to_thread(...)` protects only the awaiting task. If that task is cancelled the context manager releases the lock immediately while Python keeps running the worker thread, so a second skills or MCP writer could acquire it and operate on extensions_config.json concurrently with the first worker — reopening the lost-update window this was meant to close. The per-event-loop keying had a second hole: writers on different loops got different locks and so did not exclude each other at all. Replace it with a process-wide threading.Lock acquired *inside* the worker that performs the RMW (`_write_extensions_skill_state` and `_apply_mcp_config_update`), so ownership belongs to the thread doing the writing and is held until the write and reload actually finish, regardless of what happens to the caller. A threading.Lock also has no event-loop affinity. Adds a cancellation regression: the skills worker is paused inside the lock, its route task is cancelled, and the MCP writer is started — the MCP RMW must not enter until the skills worker is released. Against the previous asyncio-lock design this test fails with ['skills-enter', 'mcp-enter']. The two existing serialization tests instrumented by replacing the worker functions, which now bypasses the lock under test; they instead patch inside the real workers (each module's reload_extensions_config, the last step under the lock) so the production lock is exercised. --------- Co-authored-by: ly-wang19 <ly-wang19@users.noreply.github.com> Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(dingtalk): support inbound file and image attachments (#4423)
* feat(dingtalk): support inbound file and image attachments DingTalk previously dropped picture and file (document) messages because `_on_chatbot_message` ignored any message with empty text, so users could not send files to the agent. This adds inbound attachment support, mirroring `FeishuChannel`: - `_extract_files` parses `picture`/`richText` image downloadCodes and `file` (document) descriptors. `dingtalk_stream.ChatbotMessage.from_dict` does not parse `file` messages, so `_DingTalkMessageHandler.process` stashes the raw callback payload on the message (`_df_raw_data`) for the document descriptor. - `receive_file` downloads each attachment by `downloadCode` via the robot `messageFiles/download` OpenAPI, persists it into the thread uploads bucket, syncs it into a non-local sandbox, and prepends the sandbox virtual path to the message text so the agent can read the file by path. - Filenames go through the shared `uploads.normalize_filename` helper, which strips directory components and rejects traversal patterns. Outbound `send_file` already existed; this completes DingTalk file parity with Feishu on the inbound side. Adds 21 tests covering extraction, download-by-code, persistence/sandbox sync, filename sanitization, and the handler raw-data stash. * fix(dingtalk): address inbound-file review feedback Follow-up to the review on #4423: - Make the fallback filename safe by construction. `download_code` is attacker-controllable webhook data and was embedded into `fallback_name` unsanitized; it only avoided escaping the uploads directory because the resulting write failed with OSError. It is now restricted to `[A-Za-z0-9_-]` before use. Covered by a test that reproduces the old behaviour (`uploads/dingtalk_../../evil.png`) and by a test that actually exercises the previously untested `except ValueError` branch (`".."`, whose basename — unlike `../../etc/passwd` — does raise). - Log the swallowed `get_image_list()` failure instead of silently returning no images, so an SDK parse failure is distinguishable from a richText message that genuinely has no inline images. - Surface failed downloads to the agent as a short `[failed to load ...]` marker rather than silently omitting the attachment, so a user whose file did not load does not simply appear to be ignored. Keeps the cleaner text shape while restoring the signal Feishu provides. Tests: 119 passed (was 115). * fix(dingtalk): claim unique upload names and refuse symlinked destinations Round 2 review follow-up on #4423. Both findings reproduce as failing tests against the previous head. - Inbound attachments no longer overwrite each other. Generated names repeat across messages (every picture message yields "image.png", richText yields "image_0.png"), so a later attachment silently replaced an earlier one whose virtual path had already been prepended to the message text — the agent could read bytes that were not the ones its prompt referenced. The destination name is now claimed with the shared `claim_unique_filename` against the live directory contents, which also covers a real filename sent twice (`quote.xlsx`), a case Feishu's inline naming does not handle either. The claim and the write happen under one lock so two attachments cannot resolve to the same free name. - Writes go through the shared `write_upload_file_no_symlink` instead of `Path.write_bytes`. Uploads dirs may be mounted into local sandboxes, so a sandbox process could leave a symlink at a future upload name and redirect a gateway-privileged write outside the bucket; the regression test shows the old code creating the out-of-bucket target. Tests: 123 passed (was 119). * fix(dingtalk): harden the inbound download path (self-audit) Proactive hardening pass over the new inbound path; each fix reproduces as a failing test against the previous head. - Contain token failures. `_get_access_token()` sat outside the try in `_download_by_code`, and the manager awaits `receive_file` without one — a DingTalk auth hiccup during a file message aborted the whole chat turn with no reply. Token acquisition moves inside the try, and `receive_file` gains per-attachment isolation so no unforeseen error can escape past the marker. - Cap inbound size. The download buffered arbitrary bytes in memory (`response.content`) with no limit, while outbound uploads already enforce one. The body is now streamed and dropped once it exceeds `_MAX_INBOUND_FILE_SIZE_BYTES` (50 MB), surfacing as a failed-load marker. - Sanitize the failure marker. It embedded the raw webhook `fileName`; a newline could forge a standalone `/mnt/user-data/uploads/...` line inside msg.text and an over-long name bloated it. Markers now collapse whitespace and cap at 80 chars. - Keep blocking IO off the event loop. `ensure_thread_dirs`, the uploads-dir resolve, sync `SandboxProvider.acquire`, and `sandbox.update_file` all ran on the loop; directory prep now lives inside the same `asyncio.to_thread` as the claim+write, and sandbox sync uses `acquire_async` + an offloaded `update_file`. Locked by a strict Blockbuster anchor (tests/blocking_io/test_dingtalk_receive_file.py), verified to fail with `BlockingError: Blocking call to os.mkdir` when the offload is reverted. Tests: 127 + 1 blocking-io anchor (was 123); tests/blocking_io/ suite 55 passed. * fix(dingtalk): surface missing-sandbox sync as a failed load Round 3 follow-up on #4423: - When a non-local sandbox acquire succeeds but the provider cannot resolve the instance, _receive_single_file returned the virtual path anyway — a path the agent's sandbox cannot read. Mirror Feishu: log and return "", so the [failed to load ...] marker fires instead. Red-first test: test_missing_sandbox_after_acquire_yields_marker. - Drop the dead GetResponse / FakeClient.get scaffolding left in test_oversized_download_is_dropped from its red-first iteration. Tests: 128 + 1 blocking-io anchor (was 127 + 1). * fix(dingtalk): treat non-local sandbox sync failure as a failed load Round 4 follow-up on #4423. The sync except-branch logged and still returned the virtual path when acquire or update_file raised on a non-local sandbox — the same handing-the-agent-an-unreadable-path failure mode the sandbox-is-None branch was just fixed for, and exactly the leg the suite did not exercise. Feishu's except-branch returns its failure marker; DingTalk now does the equivalent (return "" so the failed-load marker fires). Red-first test: test_update_file_failure_yields_marker. Tests: 129 + 1 blocking-io anchor (was 128 + 1). --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat: add Lark CLI integration (#3971)
* feat: add lark cli integration * fix: polish lark integration actions * feat: support lark incremental permissions * fix: detect lark authorization completion * fix: harden lark integration install * feat: expand lark auth scopes and reuse host auth in sandbox Default lark auth to least-privilege (recommend=false, base sign-in only) and expose the full set of lark-cli --domain business domains as native --domain grants instead of a 4-domain read-only mapping. Resolve the skill pack from the latest larksuite/cli GitHub release at install time with content-hash integrity, and surface version/runtime drift in status. Share the per-user lark-cli config/data profile between the Gateway Settings auth flow and agent conversations by mounting the integration dirs into the AIO sandbox and injecting the matching env for lark-cli commands, with an allowlisted extra_mounts path in the provisioner/K8s backend and traversal guards on integration paths. * style: fix lint issues from ruff and prettier Sort imports in the provisioner PVC test and re-wrap two long i18n description strings to satisfy backend ruff and frontend prettier CI. * fix(lark): address managed integration review feedback * fix(frontend): stabilize integrations settings e2e * test(sandbox): isolate remote backend legacy visibility check * test: fix backend unit failures after merge * Harden Lark integration review fixes * Format Lark integration E2E test * fix(lark): harden sandbox credential exposure and status disclosure Address willem_bd's security review on PR #3971: - Mount the per-user lark-cli config dir (long-lived appSecret) read-only into the AIO sandbox; only the refreshable-token data dir stays writable. - Redact host filesystem paths (install_path, cli.path) from GET /lark/status and the config/auth complete responses for non-admin callers, fail-closed on any auth error. - Document the npm postinstall trade-off (--ignore-scripts is not viable because @larksuite/cli fetches its platform binary in postinstall). - Document the sandbox credential trust boundary in AGENTS.md and README, pointing at the sidecar-broker follow-up (#4338). --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(skills): offload blocking filesystem IO in get_custom_skill_history (#3563)
* fix(skills): offload blocking filesystem IO in get_custom_skill_history
The GET /api/skills/custom/{name}/history handler ran its storage probes and the
per-skill .history read directly on the asyncio event loop:
get_or_new_skill_storage(), custom_skill_exists(), get_skill_history_file().exists()
and read_history() are all blocking filesystem IO. make detect-blocking-io flagged
the existence probe (routers/skills.py:224) as DIRECT_ASYNC.
Move the whole read into a nested sync function run via asyncio.to_thread; a None
return signals 404 (distinct from an empty history list). Behavior is unchanged.
Per the blocking-io-guard SOP:
- Candidate: get_custom_skill_history (FILE_METADATA, DIRECT_ASYNC) -> FIX+ANCHOR.
- Re-scan: the finding no longer appears for this handler.
- Anchor: tests/blocking_io/test_skills_router.py drives the real handler against a
real on-disk skill + history; teeth verified red (pre-fix) -> green (post-fix)
under make test-blocking-io.
Scoped to this self-contained read handler. rollback_custom_skill and update_skill
also touch blocking IO but interleave it with awaits (security scan / cache refresh)
and do a read-modify-write, so offloading them needs the asyncio.Lock serialization
treatment (cf. #3552) and is left as a separate fix unit.
* test: trim dead skills history setup
* fix(skills): use the user-scoped storage accessor in the offloaded history read
The merge with main left the offloaded reader calling get_or_new_skill_storage,
which is not defined in this module (ruff F821), so lint failed and the handler
would raise NameError at runtime. Use _get_user_skill_storage(config) — the same
accessor every other handler in this router uses.
Also update the regression test for the current route signature: the handler is
now admin-only and takes a Request, so the test supplies request.state.user
(mirroring tests/blocking_io/test_channel_runtime_config_store.py) and seeds the
history through the same user-scoped accessor.

feat(agents): database-backed storage for custom agent definitions (#4359)
* feat(agents): database-backed storage for custom agent definitions Add an agent_storage.backend switch (default file, behaviour-unchanged) with a db backend that stores each custom agent as a row in the shared SQL persistence layer, so a multi-instance deployment sees the same agents on every node (#4331, #4357). Introduces an AgentStore interface routing all read/write surfaces, an agents table + migration 0006, startup validation, and a file->db importer. Follows the thread_meta store / run_events backend-switch / 0003_scheduled_tasks migration patterns; no new dependency. * fix(agents): make db storage path production-ready (review round 1) Addresses review feedback on the db/sync agent-storage path: - sql.py: mirror the async engine's per-connection SQLite PRAGMAs on the sync engine (busy_timeout=30000, synchronous=NORMAL, foreign_keys=ON, WAL) so both engines behave identically against the shared DB; guard the engine cache with a lock (double-checked) so concurrent first-touch cannot build duplicate engines or register the connect listener twice. - routers/agents.py + routers/assistants_compat.py: offload the sync-store reads that ran on the event loop (list/get/check, update's pre-read + legacy guard + refresh, and assistants_compat's four list routes) via asyncio.to_thread — on db+postgres each was a network round trip stalling the loop. Writes were already offloaded. - file.py: translate the create() mkdir(exist_ok=False) race FileExistsError into AgentExistsError (router 409, matching SqlAgentStore's IntegrityError path); correct the _write docstring — per-file atomic replace, two commits sequential not transactional. Tests: sync-engine PRAGMA + engine-cache reuse assertions; file create-race -> AgentExistsError; strict Blockbuster anchor over the read endpoints so a regression back onto the loop fails CI. * fix(agents): address round-2 review on the db store path - update_agent tool: align the docstring/inline comment with FileAgentStore._write. Cross-field write atomicity is db-only; the file backend commits config then soul via two sequential os.replace (a crash between them can leave a fresh config.yaml beside a stale SOUL.md). The dropped partial-write *reporting* is an intentional tradeoff — the stage-then-replace safety is preserved (test_update_agent_soul_failure_does_not_replace_config still holds). - SqlAgentStore.update(): true upsert. Catch IntegrityError on the insert-on-missing branch, re-fetch and apply, so two concurrent first-time writes (e.g. two setup_agent handshakes) converge instead of surfacing a raw UNIQUE(user_id, name) violation as a 500. Symmetric with create(). - get_agent_store(): document the graph-subprocess config-resolution invariant (the except->file fallback is a genuine no-config path, not a mask for a misconfigured graph process) and pin it with two tests driving the real get_app_config() file resolution: db resolves from an on-disk config.yaml, file fallback when config is unresolvable. * test(agents): cover SqlAgentStore.update() write-race upsert recovery Mandatory-TDD test for the round-2 fix in 0680340a: two concurrent first-time update()s where the loser's insert hits UNIQUE(user_id, name). Deterministically forces the IntegrityError recovery path by making the first _row probe miss the committed winner, and asserts last-writer-wins instead of a surfaced 500. |

fix(sandbox): stop multi-worker orphan reconcile from killing peer sandboxes (#4221)
* fix(sandbox): stop multi-worker orphan reconcile from killing peer sandboxes Docker sandboxes are shared across gateway workers, but each worker kept its own in-memory warm pool. Startup reconciliation adopted every running container, so a peer idle reaper could destroy sandboxes another worker still owned and tool calls hit 502 / Connection refused. Add file-based ownership leases under sandbox-leases/, only adopt true orphans, refuse idle/replica/shutdown destroy while a foreign lease is live, and renew the lease on create/get/release/reclaim. Fixes #4206 * fix(sandbox): close lease fail-open, hot-path IO, and check→destroy race Address review of the multi-worker orphan lease (#4206): - read_lease returns None only for a genuinely-absent lease and raises (CorruptLeaseError/OSError) when a lease is unreadable or corrupt, so the ownership check fails closed instead of mistaking an unprovable peer lease for a free container. clear_lease still removes a stuck/corrupt file. - get() no longer renews the lease (blocking mkdir/fsync/os.replace on the event loop path used by ensure_sandbox_initialized_async); active leases are renewed off the event loop from the idle checker (_renew_active_leases). - The ownership check and container stop run under a per-sandbox flock guard (lease_ownership_guard); every lease write takes the same guard so a peer's touch cannot interleave with a destroy. Same-host multi-worker scope, not a multi-pod distributed lock. Also fixes the ruff format lint on the branch. Adds regression tests: corrupt and unreadable lease fail closed, a tests/blocking_io anchor keeping get() non-blocking on the event loop, and a peer-touch/destroy interleave test. * fix(sandbox): share container ownership across gateway instances Rework of the #4206 fix per review: ownership state is shared through a third-party service instead of being maintained per gateway instance, following the stream_bridge precedent (sandbox.ownership.type: memory | redis). The file lease and its same-host flock guard are deleted, not ported — they only covered workers on one host, while the deployment that hits #4206 is a load-balanced multi-instance gateway. A lease answers "who reaps this container", not "who may use it". Containers are deterministic per (user, thread), so consecutive turns legitimately land on different instances: take() transfers ownership on acquire, while claim() gates every adopt/reap path. Leases carry a state — own: or del: — so a takeover is refused against a teardown in progress. Without it an unconditional take() would overwrite a destroyer's claim and the peer's container stop would land on a sandbox the new owner had already handed to an agent. renew() distinguishes a lapsed lease from one a peer took; only the latter drops the sandbox. Collapsing them meant a Redis restart evicted every in-flight sandbox on every instance at once. Renewal runs on its own thread with a TTL derived from its interval, never from idle_timeout: renewal used to ride the idle checker, which does not start at idle_timeout: 0, so leases silently lapsed on a supported config. Ownership establishment is fail-closed: a sandbox whose ownership cannot be published is never handed out, and a just-created container is destroyed rather than leaked as an adoptable orphan. Every destroy path claims before untracking. The memory store is single-instance only and says so; the resolver reads app_config.stream_bridge and the env var in the bridge's own order, so deployments already using Redis get a redis ownership store without extra config. * fix(sandbox): wait out a recovery grace before adopting a keyless container An absent ownership lease meant two opposite things on two paths. Renewal reads it as LAPSED and re-establishes it: nobody took the lease, so the container is still ours. Reconciliation read the same absent key as "orphan" and adopted on sight. After the store loses its keys (a Redis restart without persistence, or eviction under maxmemory) every owner is alive and merely pre-renewal-tick. Whichever instance reconciled first therefore adopted every live container; each real owner's next renewal reported LOST and dropped a sandbox it was serving mid-turn, leaving it for the adopter to idle-destroy — #4206 through the back door, in the very case the LAPSED handling was added to make safe. Not limited to startup: an already-running instance hits the same window from the idle checker's periodic reconcile. _adoptable_after_grace requires an untracked container to be seen unowned across a full lease TTL before it can be adopted. That rebuilds the delay the state loss erased: a live owner republishes within one renewal interval, shorter than the TTL by construction, while a crashed owner never does, so its containers are still adopted one grace later rather than leaking. A republished lease resets the grace; a pausing-only timer would still expire over a live owner's lease. The peek is read-only — the atomic claim still gates adoption. The grace is skipped when the store cannot coordinate across processes: no peer can hold a lease such a store would show us, so single-instance deployments keep instant orphan cleanup, and a grace could not help a multi-worker gateway on memory anyway. * fix(sandbox): hold the teardown lease for as long as the container stop runs claim(..., for_destroy=True) wrote the del: marker with the ordinary lease TTL and nothing refreshed it. renew() extends only own: and deliberately reports a teardown as LOST, and the destroy paths drop the sandbox from the maps the renewal loop iterates — so a container stop that outlived the TTL let the marker lapse, a peer's take() succeeded against the still-running container, and the stop then landed on the turn that had just been handed it. That is the exact window the del: state exists to close, reopened by its own expiry. The two lease states alone never made the per-sandbox flock redundant, as I claimed when deleting it: a held lock cannot expire, a lease can. The exclusion has to be held deliberately rather than assumed to outlast the work it guards. _held_teardown_lease wraps both _backend.destroy() call sites and re-claims the marker every renewal_interval_seconds until the stop returns. No store change is needed: claim(for_destroy=True) already refreshes an existing del: marker on both backends. Reachable without an abnormal backend. The schema bounds only renewal_interval_seconds (> 0) and ttl_multiplier (>= 2), so a legal config puts the TTL below a normal container stop; and LocalContainerBackend._stop_container passes no timeout to subprocess.run, so a wedged daemon blocks unbounded even at the default 120s TTL. The TTL stays finite on purpose: the heartbeat dies with the process, so a destroyer that crashes mid-stop still releases the container one TTL later instead of marking it undestroyable forever. * fix(sandbox): hold the teardown lease on every del: stop, and pin the claims that had no test 90936b49 said `_held_teardown_lease` wrapped "both" `_backend.destroy()` call sites. There are three. `_drop_unhealthy_sandbox` marks `del:` and then blocks on the same unbounded stop, and it untracks *before* claiming, so `_renew_owned_leases` cannot see the id either — nothing refreshed the marker. Reproduced against a real redis: the peer's `take()` succeeds 1.0s into a 2.5s stop. Same window, third path. That miss came from the habit the rest of this commit addresses: a property asserted in prose, with no test that could falsify it. Auditing every load-bearing claim in this feature — AGENTS.md, the store docstrings, the provider's design comments — against the test that would go red turned up several more, each verified by mutating the code and watching the suite stay green. Tests that could not fail: - `test_reconcile_fails_closed_when_ownership_unknown` reached the grace gate, not the claim. A bare MagicMock answers `owner()` with a truthy mock, so the container read as peer-owned and deferred; `claim()` was never called. It stayed green with `_claim_ownership` failing open. Adding the grace ahead of the claim is what hollowed it out — inserting a gate can silently disarm the tests for the gate behind it. - `test_adoption_grace_restarts_when_a_live_owner_republishes` never distinguished reset from pause. Those diverge only on a *second* lapse, which it never drove, so it passed with the reset deleted. Claims with no test at all, each now pinned (mutation → red, per test): - `destroy()`, `_evict_oldest_warm`, `_reclaim_warm_pool_sandbox`, `_register_created_sandbox` and `shutdown()`'s warm loop were each the one untested sibling of an "every path does X" enumeration. `shutdown()` was never driven with a non-empty warm pool, so a loop bypassing the ownership claim — stopping a live peer's container on our exit — went unnoticed. - Renewal's unknown-is-not-lost rule, the single deliberate exception to fail-closed. Inverting it drops every active and warm sandbox on every instance the moment the store blinks. - Both hops of the stream-bridge redis inference. Deleting either left the suite green while every config.yaml-native multi-instance deployment silently fell back to memory — #4206 reopened on exactly the deployments the inference exists for. Claims narrowed instead, because they promised more than the code delivers: - "run against both backends ... cannot drift" — CI provisions no redis, so the merge gate runs the memory tier only and the Lua never executes there. - "Every destroy path claims before untracking" — `_drop_unhealthy_sandbox` untracks first, deliberately, under its `expected_info` TOCTOU guard. - "Atomic: concurrent claims from different instances cannot both succeed" — true via Lua on redis, vacuous on the single-instance memory store, and pinned by neither, since the contract suite drives sequential calls. A concurrency test against the memory store would make the claim look covered while the mechanism that carries it still never runs in CI. * fix(sandbox): release the teardown marker when a destroy() stop fails The three `del:`-marked stop paths disagreed on failure. `_destroy_warm_entry` releases on both outcomes and says why: the stop failed, so the container is probably still up, and a marker left behind refuses its own thread's `take()` until the TTL lapses. `_drop_unhealthy_sandbox` does the same. `destroy()` had no such guard — a raising backend propagated straight past `_release_ownership`, and the thread could not re-acquire for a full TTL. Fails safe rather than fatal: a stuck marker stops peers from touching the container, it is not the cross-instance kill. But the paths must agree, and this one is the odd one out. Release, then re-raise. Swallowing would be the easier symmetry with `_destroy_warm_entry`'s `return False`, but `destroy()` has no failure return and `shutdown()` logs per sandbox off the exception, so swallowing would silently narrow what callers can see. Found by comparing the three paths after @fancyboi999 asked for release to be handled "consistently with the other destroy paths" on the unhealthy path — which 0d2377b2 already does. This is the sibling that wasn't. * fix(deploy): bump chart config_version to 27 for sandbox.ownership config.example.yaml went to 27 with the new sandbox.ownership section, but the chart embeds its own copy and stayed at 26, so validate-chart failed. A bare bump: the chart already sets stream_bridge.type=redis, which is what resolve_ownership_config infers a redis ownership store from, so no field change is needed. * fix(sandbox): release the teardown lease from its heartbeat, not the caller `_held_teardown_lease` joined its heartbeat only briefly and the caller cleared the `del:` marker right after the stop. A refresh `claim` still in flight (`RedisOwnershipStore` had no socket timeout, so a round trip could block) could land *after* that release and rewrite `del:` on a container whose stop had already completed — refusing a fresh `take()` (or rolling back a fresh create) until the TTL. Move the release into the heartbeat's own `finally`, after its loop stops, so no refresh can run after it. The three destroy paths no longer release after the `with` (`destroy()`'s no-container branch still does, since no lease was held there). Bound every store round trip with a socket timeout so the in-flight refresh — and thus the deferred release — stays finite, and broaden the heartbeat's `except` so an unexpected error cannot strand the marker during a long stop. Also fold in the review follow-ups: stop re-resolving an already-resolved ownership config in the factory, document the Redis-outage-vs-TTL boundary in config.example.yaml, and add a tests/blocking_io anchor pinning that `release()`'s store round trip stays off the event loop. * fix(sandbox): refuse a non-destroy claim that would unwind our own teardown `claim(for_destroy=False)` against our own `del:` lease fell through and overwrote it with `own:`, cancelling a teardown that was already in flight. The container stop cannot be recalled, so downgrading the marker would let a `take()` hand out a container that is about to die -- #4206, self-inflicted. No caller does this today: the two non-destroy callers run against an absent key (the LAPSED re-claim) or an unowned one (post-grace reconcile). The contract has to forbid it rather than rely on that staying true. Fixed in both backends. The redis rule lives in Lua and the memory rule in Python, so fixing one only would let them drift silently -- and the shared contract suite is what is supposed to catch that drift, so it now covers this. Also adds a contention test for `claim`. The suite drove sequential calls only, so it pinned the exclusion predicate but not the atomicity that predicate depends on; eight instances now race for one container and exactly one must win. * fix(sandbox): bound the container stop so it cannot outlive its teardown lease `_stop_container` passed no `timeout` to `subprocess.run`, so a wedged container runtime blocks it forever. The `del:` marker is what keeps a peer from re-acquiring the container while the stop runs, but a marker is a lease and a lease can lapse: a store outage longer than the TTL frees it, a peer's `take()` succeeds against the still-running container, and the stop then lands on the turn that was just handed it -- the exact #4206 failure. The teardown heartbeat already covers the case where the store stays reachable. This bounds the worst case independently of the ownership layer, which is the point: it holds even when the ownership layer is the thing that failed. A timeout is not swallowed like a `CalledProcessError`. That error means the runtime answered "I could not stop it"; a timeout means we do not know, and the container is probably still running -- returning normally would let `_destroy_warm_entry` report a clean stop and drop the warm entry, leaking a running container nothing tracks. * fix(sandbox): exclude this instance's own reapers from its acquire path An ownership lease excludes peers and nothing else. `claim()` and `take()` both succeed against our own `own:` lease by design -- that is what lets a destroy path claim what it already owns -- so `del:` says nothing to this process's other threads. Meanwhile every reaper decides outside `_lock`, because a store round trip must not be held under the lock that guards every acquire. So each reaper acts on a decision its own acquire path may already have invalidated, and the store cannot see the difference. Six paths end in an irreversible act (a container stop, or closing a host-side client) on a decision made outside the lock. All six reproduce: _evict_oldest_warm re-checks warm membership, then releases the lock _reap_expired_warm no re-check at all _cleanup_idle_sandboxes re-verifies idle, then releases the lock _renew_owned_leases acts on a stale renew() -> LOST release() same staleness on its own refresh _drop_unhealthy_sandbox untracks before claiming, opening discovery Both warm reapers are a regression from the deferred pop this branch introduced: `WarmPoolLifecycleMixin` popped under the lock, so a reclaim's membership check failed and the race could not occur. Deferring the pop is still right (popping first loses the container on a refused claim), so the exclusion has to be made explicit instead. The idle path is pre-existing in shape, but this branch widened it from a few instructions to a network round trip by claiming ownership before untracking. Two guards, because the two directions want opposite answers: Reaping -- nothing may promote it. The reaper reserves the id, and every promote path refuses a reserved id exactly as it refuses a peer's `del:` (drop and cold-start). The "is this still reapable?" test travels with the reservation as a predicate and runs in the same critical section, because checking first and reserving second is the window, not a narrower version of it. Forgetting -- the peer legitimately wins, so the promote is what to detect. `_publish_ownership` bumps a per-id acquire epoch; the callers that decide from a store round trip snapshot it first, and the pop is skipped if it moved. Object identity cannot substitute: the reuse path re-publishes ownership while handing out the same tracked `AioSandbox`, so an identity check sees nothing and the pop closes a client mid-turn. `still_reapable` is required rather than defaulting to unconditional -- the safe default is the one that makes a new call site think about it. That diverges from the mixin hook, which is safe because this provider overrides both mixin callers, and loud rather than silent if those are ever dropped. Also closes a client leak on the discover path: "nothing to roll back" was true of the container but not of the HTTP client constructed before the publish, which the sibling create path already closes. The shared-store test view rebound `owner_id` outside the store's lock, so a concurrent claim could execute under the wrong id and read its own lease as a peer's. Serialized, so the heartbeat-hold tests stop flaking. * fix(sandbox): mark acquire intent before the ownership round trip A guard must become visible no later than the transition it guards. The acquire epoch cannot manage that for `take()`: the takeover is durable before `take()` returns -- redis has committed the SET while the reply is still in flight -- and the epoch can only be written afterwards. In that interval the store already says the container is ours while the epoch still reads as it did when a renewal decided `LOST`, so the stale forget walks through, drops the maps and closes the client the acquire is about to hand back. Acquire then returns an id the provider no longer tracks and `get()` answers `None` for the rest of the turn. `_publish_ownership` now publishes an intent mark under `_lock` before the round trip; the epoch keeps covering the other half, "an acquire completed since you decided". `_forget_lost_sandbox` honours the intent mark unconditionally rather than only when an epoch is supplied -- today's epoch-less callers cannot reach the window, but "no epoch" reading as "no guard" is how the next caller of a dangerous primitive gets written. The same invariant had four more instances, all reproduced: reuse returns a decision the forget already invalidated -- before the mark is set a `LOST` is both current and correct, so the forget legitimately runs and the entry reuse decided to hand out is gone. Re-check after publishing and fall through to discovery instead. reclaim installs an entry a reaper reserved after its check -- the warm entry is still visible during the stop, and the reaper's claim succeeds because reclaim's own take() just made the lease ours. Re-check likewise. the reservation was released before the entry was removed -- the pop belonged to the caller, leaving a gap where the container is stopped, the entry is still in `_warm_pool`, and nothing marks it. `_destroy_warm_entry` removes it itself, inside the reservation; the pop stays deferred relative to the stop, just not to the reservation. reconcile adopts a container this instance is tearing down -- adoption is a promote and needs the same reservation check as the others. Neither existing guard excludes it: the claim succeeds because the lease is ours, and on `memory` the recovery grace is skipped outright. The pre-round-trip checks in reuse and reclaim are kept as early-outs, since they skip a health check and a store round trip on a doomed entry, and are pinned to that job rather than to a correctness role they no longer hold. The teardown reservation predicate runs under `_lock`, so it must not touch the lock. Documented rather than engineered around: making the lock reentrant to tolerate it would trade a loud hang for a quiet class of re-entrancy bugs across the rest of the provider. * fix(sandbox): honor local teardown after ownership publish * fix(sandbox): clear a stale warm entry when an id becomes active Active and warm are exclusive states, and the two register paths were the only place that could hold both: they inserted into `_sandboxes` without popping `_warm_pool`, so one container ended up with two reapers. `_reap_expired_warm` judges an entry by its warm timestamp and never consults `_last_activity`, so it stops a container an agent is actively using while `_sandboxes` still hands out its client. Reachable because `_reconcile_orphans` adopts an untracked-but-running container into the warm pool inside the register's publish -> track window, and on the `memory` store it adopts on sight: `_adoptable_after_grace` short-circuits when `supports_cross_process` is False, so an id carrying this process's own lease reads as adoptable. That window is new to this branch -- on main the track was a single locked insert with nothing before it. Both register paths now pop the warm entry inside the same locked section that installs the active one. * fix(sandbox): harden ownership renewal teardown --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(artifacts): serve inline binary artifacts via FileResponse for Range support (#4281)
* fix(artifacts): serve inline binary artifacts via FileResponse for Range support Audio/video/image artifacts that are previewed inline (not downloaded, not active content) were served by reading the whole file into memory and returning it through a plain Response. That response never sets Accept-Ranges and ignores any Range header the browser sends, so seeking an <audio>/<video> element backed by this endpoint always gets the full 200 response back instead of a 206 partial response for the requested byte range -- which is why dragging the seek bar on an audio artifact restarts playback from the beginning instead of jumping to the new position. Route this case through FileResponse instead (as the active-content/ download branch already does), which handles Range/If-Range natively. Verified with a real Range request against the endpoint: initial load now reports Accept-Ranges: bytes, and a ranged GET returns 206 with the correct Content-Range and only the requested slice of bytes. Fixes #3240 * fix(artifacts): address review nits on the inline FileResponse branch Two non-blocking nits from review: - Drop the redundant filename= kwarg on the inline_file FileResponse call. Content-Disposition is already set explicitly on this branch, and FileResponse only uses filename to setdefault that same header -- which is a no-op once it's already present. Harmless today, but removes the latent risk that a future Starlette version turning that setdefault into a hard set would silently flip inline preview to attachment. - Reword the blocking-IO regression-anchor docstring: it claimed awaiting get_artifact for a binary artifact does "zero filesystem IO", but _read_artifact_payload still runs exists/is_file/ mimetypes.guess_type/is_text_file_by_content (an 8 KB read) for binary files too, just offloaded via asyncio.to_thread like the text branch. The gate has nothing to catch because that IO is off the event loop, not because there's none -- reworded to say no full-file read happens, matching the accurate framing already used one paragraph up. tests/test_artifacts_router.py, tests/blocking_io/test_artifacts_router.py (19 tests) are green, and ruff check/format are clean on both changed files. |
