fix(middlewares): end length-capped turns cleanly, prevent todo re-engagement, annotate write_file budget (#5569)
* fix(middlewares): end length-capped turns cleanly, prevent todo re-engagement, annotate write_file budget When a model hits its per-response output cap (finish_reason=length) while emitting a write_file tool call, ModelLengthFinishReasonMiddleware suppresses the truncated call and stamps model_length_termination. TodoMiddleware must not re-engage (jump_to=model) on such a capped turn -- doing so re-emits the same oversized call into the same cap, producing up to 3 futile responses with junk fragments instead of a clean truncation notice. Changes: - TodoMiddleware.after_model: skip completion reminder jump when additional_kwargs.model_length_termination is present (follows the existing deerflow_error_fallback precedent). - ModelLengthFinishReasonMiddleware: always append the length notice when tool calls were suppressed, even when partial text survived (collapses the visible-content ternary). Fixes a latent bug in append_visible_text that silently dropped string content. - tools.get_available_tools: annotate write_file's model-visible description with the model's configured max_tokens output budget. Guarded extraction safely handles missing or non-numeric tokens, and the tool is cloned via model_copy to keep module-level singletons immutable across assemblies and prevent guidance leakage to unbudgeted models. - release_policy_parameters() updated for both middlewares. - AGENTS.md chain entries (#20, #35) and module docstrings updated within AG002 guidance limits. - Tests: 8 new/focused unit tests + 1 updated pin + 1 real create_agent() integration test reproducing the incident (thread b1723286). * fix(tools): use effective model cap for write_file guidance --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(middleware): add deterministic PII redaction for model-bound context (#5527)
* feat(middleware): add deterministic PII redaction for model-bound context * fix(middleware): claim national IDs before cards, redact Command results, preserve ToolMessage fields - Reorder detectors so checksum-gated national IDs run before the credit-card detector; an 18-digit resident ID whose digit run also passes Luhn is no longer mislabeled [CREDIT_CARD_n] (review finding, reproduced at 0a2a9d0) - Redact ToolMessages carried in Command.update.messages, mirroring ToolResultSanitizationMiddleware's dc_replace pattern - Rebuild redacted ToolMessages via model_copy so artifact and response_metadata survive - Extend the numbered middleware chain in agents/middlewares/AGENTS.md * fix(middleware): span one redactor per Command result; refresh stale AGENTS.md entry range - Placeholder numbering now continues across every ToolMessage carried in a single Command result (one _Redactor per _redact_result call) instead of restarting per message - The renumbered AGENTS.md chain still referenced entries 9-12 in the ToolReceiptMiddleware entry; it now reads entries 10-13 * docs(agents): trim PiiRedactionMiddleware entry to fit the AGENTS.md chain budget The main merge (fb36e0e) pushed the effective middlewares chain to 98341 bytes, 37 over the 98304 hard limit checked by agent-guidance (AG002). Compress the entry while keeping the load-bearing facts: config gate, both interception points incl. Command coverage, detector order rationale, per-result numbering continuity, irreversibility, memory follow-up. * fix(middleware): redact compaction input and reinjected summaries; harden detectors Review round 3 on #5527: - [P1] SummarizationMiddleware invokes its summary model directly from before_model, outside PiiRedactionMiddleware's wrap_model_call, so raw thread state reached the summary model and reinjected summaries carried raw PII into model-bound context. Add a shared redact_text() seam: the compaction prompt is redacted in _build_summary_prompt (app_config already flows into the middleware) and DurableContextMiddleware redacts summary_text at reinjection via a new pii_redaction_config knob wired at both assembly sites. - [P2] CUIT is 2+8+1 digits, not 2+10+1. - [P2] Digit-anchored patterns use digit-aware lookarounds instead of Unicode \b, which CJK characters defeat (身份证110105… / 手机号138…). - [P2] The international-phone pattern no longer treats newlines as separators, so a candidate cannot swallow the following numeric field and then fail validation as a whole. * fix(pii): redact title input and reserve summary placeholders --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash (#5443)
* feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash Implements docs/superpowers/specs/2026-09-12-projects-mvp-phase2-design.md (issue #5160, tracker #5129) in the slice order of the spec's §16. Slices: - A: ProjectsConfig + write-time 422 UTF-8 byte cap; PROJECT_CONTEXT_KEY admission pinning (both server-owned sets + worker hoist); latest-only request-scoped <project> block via DynamicContextMiddleware wrap_model_call/awrap_model_call (idempotent reassembly, reserved ID prefix + marker + provenance, never persisted); journal audit fingerprints; Instructions tab. - B: ProjectDocumentRow + migration 0023; ProjectDocumentRepository with locked check-and-set; hash-qualified immutable shelf storage with Paths helpers; upload/list/content/delete-to-trash routes; project delete trashes the shelf in-transaction; request-scoped bounded <documents> index with honest count/shown + actionable overflow note; list_project_documents/read_project_document tools registered only on pinned runs; PAT allowlist + drift guards; blocking-IO anchors. - C: shared thread-upload ingestion service (uploads router refactored to parity); POST from-thread with provenance; attach-to-thread with lock-staged copy (archived source allowed); read-only thread-files view with per-group truncation reporting. - D: restore (restored/merged/not_found/no_target/content_missing; no file moves), purge (continuous row lock across unlink/delete/commit, retryable on FS errors), retention sweep (lazy + startup, 24h orphan guard, row-side reconciliation never deletes). - E: Documents tab (shelf + conversation-files browser, provenance, archived banner, content-missing rows), /workspace/trash route, sidebar entry, composer attach handoff, i18n (en-US/zh-CN), e2e mocks + specs. Review hardening folded in (10 rounds, all with tests): - force active shelf content (HTML/XML family) to download; nosniff on artifact + content responses; unified unsandboxed-iframe PDF preview (fixes the pre-existing Chromium sandbox blank in the artifact viewer) - scope document trash to the URL project under the document lock - atomic no-overwrite filename reservation for ALL ingestion (seeded claims + os.link commit with suffix retry; same-name re-upload now unique-names instead of replacing); hidden staging only, no visible placeholders; lease cleanup on setup failure - serialize conversion under the document lock with post-lock active revalidation; drain locked filesystem work on cancellation; preserve bytes when an insert's commit state is uncertain (including trashed rows) - original-integrity checks before serving text or cached conversions; content_missing surfaced in list responses (UI reads the flag, no 409-probe); downloads always serve original bytes - bounded streaming document reads with cached char counts; shelf limits declared in middleware release identity - thread-root confinement for from-thread sources; config fallback rejects fractional/infinite values; composer counts staged attachments; pending attachments persist until submission or removal; in-flight instruction/rename edits survive save refetches; shelf and trash pagination; conversation-file and thread-files pages stay subscribed to refetches Docs: README/README_zh, backend API.md/ARCHITECTURE.md, AGENTS.md contracts, config.example.yaml projects block. Review follow-ups (head b4807477 → this revision): - The trash retention sweep is split so repeated lazy triggers stay bounded: the indexed expiry purge still runs on every trigger (GET /api/trash/documents, POST /api/trash/purge) while the O(all rows + all files) reconciliation is throttled to one run per user per 15 minutes (process-local, per-user window). The startup sweep now runs as a background task instead of blocking gateway readiness, and shutdown awaits it (bounded). - The export scrub (stripInternalMarkers) is fence- and indentation-aware like the render path, so a pasted, fenced <project>/<documents> snippet survives markdown export while real injected blocks (never fenced) are still removed. Fence regexes moved to a dependency-free leaf module to avoid the messages↔streamdown import cycle. - The artifact viewer's PDF iframe no longer carries an added title attribute (the upstream e2e contract locates it via :not([title])), and the upstream artifact-preview spec now pins the new contract: PDFs render unsandboxed, images keep sandbox="". * fix(projects): round-2 review — cancel an overrun trash sweep, restore the PDF frame title - Shutdown cancelled only the shield around the background startup sweep, so an all-users reconciliation that outlived the 5s budget kept walking rows and files while the document repo and DB engine were disposed underneath it. The wait now lives in `_shutdown_startup_trash_sweep`, which cancels the task and drains it before worker exit: the shield keeps the wait bounded, the cancel makes it final (CancelledError lands at the sweep's next await, and `_run_startup_trash_sweep` only catches `Exception`, so nothing swallows it). - The browser-preview iframe lost `title={getFileName(filepath)}` in the previous fix round, leaving the PDF frame without an accessible name while its siblings keep theirs. Restore it (WCAG frame titles), assert it in the DOM test, and anchor the e2e on `iframe[title="report.pdf"]` instead of `iframe:not([title])`. * fix(projects): round-3 review — report the sweep's late finish, not a phantom cancel `Task.cancel()` returns False when the sweep already finished inside the window between the deadline firing and the cancel, so the shutdown log claimed a cancellation that never happened. Branch on that outcome: the warning stays for a real cancel, a late finish is logged at info, and both paths still reap the task before worker exit. * fix(projects): round-4 review — make Empty trash delete what it confirms `POST /api/trash/purge` only ran the retention sweep, and the sweep's candidate selection is age-gated, so a freshly trashed document survived "Empty trash" even though the confirmation promises that every listed document is permanently deleted. With one trashed row the route answered `{"purged": 0}` and left it in place; `GET /api/trash/documents` sweeps expired rows before listing, so the visible rows were normally ineligible for the action by construction. Empty trash now drives `purge_all_trashed`: the caller's trashed rows (`list_all_trashed`, no age filter) each go through the same guarded, row-locked `purge` as the single-document delete — bytes first, then the row, in one transaction — so a row restored mid-flight is skipped instead of force-deleted, and an unlink failure rolls that row back and answers 500 with a retryable message. Retention expiry stays where it was: the sweep's `purge_candidates` is now the only age-gated selection, and the lazy retention sweep still runs on the listing and at startup. Tests: the router suite replaces the retention-gated expectation with the reviewer's repro (fresh row purged, bytes unlinked, shelf and other users' trash untouched, a failing unlink stays retryable and 500); a blocking-I/O anchor drives the new entry point through the offload; the mocked e2e covers the action end to end; a new real-backend spec performs it against the real gateway and re-reads `GET /api/trash/documents`. README, API, ARCHITECTURE and the phase-2 design docs (en+zh) state the age-independent contract. |

feat(harness): subagent report contract and delegation acceptance criteria (#5090)
* feat(harness): subagent report contract and delegation acceptance criteria (RFC #4651 PR3) Layer 1 receipt verification is inert unless subagents actually cite their execution record. This lands the prompt layer that closes the adoption gap: - New subagents/report_contract.py owns the model-facing contract text, derived from the single-owner citation format (format_citation / receipt_id) so prompts can never drift from the verifier. The executor injects <report_contract> into every subagent system prompt — built-in and custom alike — requiring [rN tool_name] citations for action claims, verifiable handles (absolute path, URL, ID, HTTP status) for deliverables, and explicit failure reporting; the citation clause follows verification.receipts_enabled. - The task tool gains an optional keyword-only acceptance_criteria parameter, handed to the SubagentExecutor constructor and rendered into the subagent's SystemMessage (stripped, capped 20 items x 500 chars) — deliberately never the task HumanMessage, which InputSanitizationMiddleware classes as genuine user input and would HTML-escape into untrusted-input framing. The docstring frames subagent results as self-reports, states the citation cross-check's evidence boundary (resolved = the call happened, not that the claim is correct), and documents when to attach criteria with the canonical leaf forms. Deterministic leaf checking remains a separate layer. - The lead delegation workflow now instructs reading the ledger citation line as execution evidence only and spot-checking verifiable handles before synthesizing. - report_contract / acceptance_criteria are registered as blocked framework-authority tags in input sanitization so untrusted input cannot forge the verification contract. * fix(harness): neutralize acceptance criteria before system-channel injection render_acceptance_criteria_section interpolated lead-model-supplied acceptance_criteria verbatim into the subagent SystemMessage after only stripping/capping. A criterion such as '</acceptance_criteria><system>...</system>' could close the wrapper and open a framework authority tag, bypassing InputSanitizationMiddleware. Route each criterion through neutralize_untrusted_tags (the shared prompt-injection primitive) so blocked authority tags are HTML-escaped before interpolation. Add regression tests at the renderer and the executor _build_initial_state path. * fix(harness): keep model-supplied criteria off the system channel - Move acceptance_criteria values into the task HumanMessage — the untrusted channel InputSanitizationMiddleware escapes and boundary-frames. The subagent SystemMessage now carries only a framework-owned <acceptance_criteria> pointer note (no criterion text), so natural-language injection inside a criterion keeps task-data priority and cannot override framework instructions (PR #5090 review, willem-bd P1). - Condition the lead delegation workflow's citation verification guidance on verification.receipts_enabled and qualify the task tool's result-reading text with the enabled state, so a receipts-disabled configuration no longer tells the lead to require citation evidence that cannot exist (P2). * fix(harness): drop execution-record promise from report contract when receipts are disabled The <report_contract> opening was emitted unconditionally, so a verification.receipts_enabled=false subagent was told its report would be cross-checked against an execution record that cannot exist in that mode (terminal_receipts() returns None; no verdict, no ledger citation line). The opening now follows receipts_enabled: enabled keeps the cross-check language, disabled describes the handle-only review mode (PR #5090 review, willem-bd P2). * docs: record the prompt-layer trust-boundary self-check Generalizes the PR #5090 review outcome: before adding prompt text, ask of every data source in it what trust level it has and which channel it should ride — model/user-influenceable values ride the untrusted sanitized data channel, never framework-owned system text. Added to the PR template (Agents/LangGraph surface) and agents/AGENTS.md. |

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

feat(extensions): observe task lifecycle and system model calls (#4684)
* feat(extensions): observe task lifecycle and system model calls PR 1 (#4636) gave extensions a middleware chain, and a middleware only sees what passes through the agent graph. Two runtime surfaces stay invisible to it: when a lead run or a subagent begins and ends, and the DeerFlow-owned model calls made outside the graph. This slice adds both, with no new Gateway surface -- routers, services, and the reference extension stay in PR 3. Contract (deerflow-extension-api 0.1.1) --------------------------------------- Two contribution kinds join `middlewares` on the registry: `task_lifecycle` (`on_task_start` / `on_task_stop`, receiving a `TaskInfo` and a conservative `TaskOutcome` of completed / aborted / failed) and `system_model_observer` (`on_system_model_call`, receiving a `SystemOperationKind`, a `SystemModelRequest` snapshot, and a `SystemModelResult` carrying either the response or the provider exception plus a duration). `SystemModelRequest.messages` normalizes to a tuple at construction. Goal evaluation and memory extraction pass a message list while title generation and summarization pass one prompt string, and a bare `str` already satisfies `Sequence` -- without normalization an observer iterating `request.messages` would silently walk characters. Copying also makes the frozen snapshot immutable in fact rather than only by declaration, since observations may run after the call site returns and keeps mutating its own list. Registry marks and rollbacks become per-bucket and positional, so an `install()` that fails after registering two different kinds cannot leave one of them behind. `needs_task_store` now covers all three kinds: a deployment that registers only lifecycle hooks still gets a task store. Task lifecycle -------------- The lead worker notifies start after the run has started and stop after completion persistence and the completion hook, but before clearing the finalizing barrier and publishing the stream end -- holding the barrier across stop is what keeps a same-thread replacement run from overlapping this task's lifecycle. Cancellation raised out of the stop notification is deferred, not propagated in place, so a cancelled run still clears the barrier and emits its end frame. A subagent with a parent `run_id` wraps its execution in the same pair inside `finally`, reporting `parent_task_id` so a delegation tree is reconstructable; a subagent without a `run_id` (embedded client, standalone LangGraph Server) logs and skips rather than inventing a parent. Contributors run in registration order inside one shared 3s budget and every failure is logged and failed open. System model calls ------------------ Four kinds cover the model calls the middleware chain cannot see: goal evaluation, memory extraction, title generation, and summarization. Each site reports both terminal paths without changing the provider exception the host observes, short-circuits on `has_system_model_observers`, and passes the live task store when the runtime has one (detached work gets an isolated store). The sync summarization half stays unobserved on purpose -- it and its only host caller are the sync side of an async-only runtime, so notifying there would block a thread on a call site the host never reaches; the reason is recorded at the call site. The DeerMem backend must stay vendorable and cannot import the extension API, so it reports through a new `MemoryCallbacks.on_memory_llm_result` host hook that the DeerFlow-side callbacks translate into an observation. Notification loop ----------------- Extension resources must be touched on the loop that created them, but subagents can execute on isolated loops and DeerMem runs on a worker thread. The Gateway registers its serving loop before any runtime dependency starts and resets it last through the exit stack, so every startup-failure and cancellation path is covered. Awaited hooks raised on another loop are dispatched across with `run_coroutine_threadsafe` and awaited under the same budget; synchronous sites submit fire-and-forget work. Shutdown stops accepting detached observations before the memory flush -- that flush runs on a worker thread and can emit memory observations -- while keeping the loop alive for awaited task hooks until run and subagent drain completes. Tests ----- `test_extension_task_lifecycle.py`, `test_extension_subagent_lifecycle.py`, and `test_extension_system_model_calls.py` cover ordering, fail-open, budget exhaustion, snapshot binding under a concurrent singleton replacement, the loop-dispatch and shutdown-suspension paths, and both terminal paths at every call site. `test_gateway_run_drain_shutdown.py` pins the stop-before-barrier and drain ordering. * fix(extensions): decide notification fail-open by origin, observe cancellation `_notify_each` only guarded `Exception`, so a contributor letting a `CancelledError` escape — an extension implementing an internal timeout with cancellation, say — skipped its successors and reached the worker's deferred-interrupt path, ending an otherwise successful run as cancelled. Fail-open is about where a failure came from, not its base class: only a genuine cancellation of the host task increments `Task.cancelling()`, so propagate on that and contain everything else. `KeyboardInterrupt` / `SystemExit` still propagate. `observe_system_model_call` skipped observers on cancellation for the same base-class reason, leaving goal / title / summarization silent on a terminal path that is routine — interrupt/rollback admission and shutdown both cancel the run task, with the provider tokens already spent. Awaiting observers there is unreliable (a repeated cancel interrupts that await before any of them runs), so report through the same non-blocking submission the synchronous memory bridge uses, then propagate the cancellation untouched. DeerMem keeps `BaseException` around its provider call, now with the reason recorded: that path runs on a worker thread, where cancelling the awaiting side never interrupts the running thread, so `CancelledError` cannot arrive at all. Its host-hook wrapper narrows to `Exception` — only the hook's own failures are non-fatal, and an observability path must not swallow a process teardown signal. * fix(extensions): warn on budget exhaustion, scope observer logs by task, propagate teardown Review response on #4684: - The memory observation bridge caught BaseException, which would swallow a teardown signal raised while dispatching; it now catches Exception, matching the boundary the DeerMem-side call site documents and tests. - A notification-budget timeout raised mid-hook fell into the generic hook-failure path and logged an asyncio-internal traceback; it now logs a warning like the pre-hook budget skip, while a TimeoutError a contributor raises on its own stays classified as a hook failure. - System model observer logs passed the operation kind as the task id, so log lines said "task goal/title/..."; they now carry the task scope id alongside the kind. |

feat(extensions): add middleware plugin foundation (#4636)
* feat(extensions): add middleware plugin foundation * fix(extensions): stop config resolution from masking extension loading `create_app()` resolved the configured plugin list inside the fail-open guard around `load_extensions()`. CI has no `config.yaml` (gitignored and never generated by the workflow), so `get_app_config()` raised `FileNotFoundError` there and was swallowed as an extension failure -- `load_extensions()` never ran at all, and the four `create_app()` tests in `test_extension_app_loading.py` passed locally but failed on every runner. Resolve the plugin list before the guard. Only an absent `config.yaml` is tolerated, mirroring `_resolve_trace_enabled_for_app_construction()`: `create_app()` runs at import time, and lifespan still performs strict config loading before serving. A `config.yaml` that exists but fails to parse or validate now propagates instead of being reported as an extension failure -- reporting it as the latter silently dropped a `required: true` extension rather than failing the boot. Make the tests config-independent with an autouse `stub_app_config` fixture, following the existing pattern in `test_gateway_lifespan_shutdown.py`, and cover both new branches of the config-resolution boundary. * fix(extensions): bind the run's extension snapshot through subagent delegation The lead-agent path resolves one immutable loaded-extension snapshot per run and binds it through task-store allocation and graph construction, but the subagent path re-read the process-wide singleton at execution time. In production both are the same object, yet a `set_loaded_extensions()` between the lead run's start and a subagent's execution (test teardown, a future hot-reload path) would let one run mix two extension generations — exactly what the documented invariant exists to prevent. The graph-build binding is a ContextVar scoped to synchronous construction, so it has already exited by the time a tool delegates; the snapshot has to travel through runtime context instead. The run worker publishes it under the host-internal `EXTENSION_SNAPSHOT_CONTEXT_KEY` (written after the caller merge, popped when the run has none, so a caller-supplied value is never authoritative), `task_tool` reads it back through the type-checking `resolve_run_extensions()`, and `SubagentExecutor` binds it at construction. Callers outside the Gateway run path — embedded `DeerFlowClient`, standalone LangGraph Server — install no snapshot and keep the existing `get_loaded_extensions()` fallback. * refactor(extensions): defer the ordering table by call, not by a lying tuple `CORE_ORDERING_CONSTRAINTS` was a `tuple` subclass that overrode only `__iter__` and resolved into a class-level `_resolved` side channel. A tuple cannot populate its own storage after construction, so the instance stayed the empty tuple it was built as: `len()` was 0, `bool()` was False, `in` was always False, indexing raised, slicing and `reversed()` came back empty, and it compared unequal to the plain tuples tests substitute for it — all while iteration yielded the real constraints. Only `assert_ordering` consumed it, and only by iterating, so the split went unnoticed. The sibling `_AnchorTable(dict)` uses the same idea soundly because dict is mutable: `self.update()` fills the real storage, making every inherited operation correct. That trick does not survive the port to an immutable type. Replace it with `core_ordering_constraints()`, matching how `stack.py` defers the same kind of table via `_anchors()`. The deferral is kept — it is about dependency direction, not just cycles: `extensions/` is the layer the middleware layer calls into, so a module-scope `agents.middlewares` import here points the dependency backwards and closes a cycle as soon as any middleware imports something under `extensions/` at module level. Resolution stays at `assert_ordering` time, which already runs inside the middleware builder. Tests pin both halves: the returned value is a plain tuple whose len/bool/ membership/indexing/reversal/equality agree with iteration, and a subprocess probe asserts importing `extensions.ordering` does not load the middleware layer while calling the function does. |

feat(authz): enforce model authorization at Gateway routes and runtime (#4063 Phase 3) (#4540)
* feat(authz): enforce model authorization at Gateway routes and runtime (#4063 Phase 3) Phase 3 / Models — the first of three resource-type PRs (Models, Skills, Sandbox). The RBAC provider already maps "model" → config key "models" (rbac.py _RESOURCE_POLICY_KEYS), so no schema change is needed. Gateway route layer (mirrors Phase 2A): - resolve_model_authorization() in authz.py returns (provider, principal), reusing _get_cached_route_provider and build_principal_from_context, including the INTERNAL_SYSTEM_ROLE → None pop for internal callers. - list_models filters via provider.filter_resources(principal, "model", names). - get_model checks provider.authorize("model", "use"). Deny → 403 (not 404, since the model exists but the role lacks permission). Runtime resolution layer (mirrors Phase 1B): - _authorize_model_name() in agent.py runs after _resolve_model_name. On deny, falls back to the first allowed model (RFC §9: graceful, not crash). All models denied + fail_closed → ValueError (matches existing contract). authorization.enabled: false is a complete no-op on both layers. Anonymous requests (user=None) bypass filtering. 18 new tests + 314 existing tests pass. * fix(authz): enforce model:use on the embedded DeerFlowClient path (Phase 3 follow-up) Round 4 review (willem-bd): _authorize_model_name only covered the Gateway runtime path (_make_lead_agent). The parallel lead-agent construction path DeerFlowClient._ensure_agent (client.py) filtered tools but not the model, so a library/embedded consumer with role-scoped model policies could run a model the role is denied model:use for. - Insert _authorize_model_name in _ensure_agent, mirroring _make_lead_agent. - Resolve None default to the first configured model before the gate so the implicit default (create_chat_model(name=None)) is also authorized. - Update test_authorization_filters_framework_tools_and_reuses_provider: the stub provider now returns an allow decision for model:use (checked during assembly) and patches resolve_authorization_provider in the agent namespace. - Add 3 DeerFlowClient._ensure_agent path tests (real-path fallback, None-default resolution, disabled no-op); 24 tests total. * docs(authz): document get_model provider-unavailable fail-open path + test zhfeng review (round 5): get_model's docstring only mentioned the deny→403 path, not the provider-resolution-error + fail-open path (which allows the request, mirroring list_models's documented fail-open semantics). The behavior itself is correct and symmetric with list_models, but it was undocumented and the _AuthorizationUnavailable path had no test coverage. - Extend get_model docstring to state the provider-error fail-closed/fail-open outcome, matching list_models's wording. - Add test_get_model_provider_unavailable_fail_closed_vs_open exercising the _AuthorizationUnavailable path (provider cannot be resolved at all), pinning fail-closed→403 / fail-open→200. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(summarization): summarize with the run model, fall back on summary-provider failure (#4361)
* fix(summarization): own the run model for compaction; bound failure With summarization.model_name: null the summary model resolved to config.models[0] while the executing model is selected per run; when they differ and models[0]'s provider is broken (expired key, quota, outage) compaction silently failed every triggered turn and context grew unbounded until the main provider 400s the run (#3103's shape), even though the run's own model was healthy. Model ownership is now sourced from the builders, not re-derived at runtime: - The lead, subagent, and manual /compact builders each pass the resolved run model into create_summarization_middleware(run_model_name=...). The middleware no longer reads runtime.context / get_config(), which do not carry a custom agent's or a subagent's resolved model, so a custom-agent lead run and a distinct-model subagent now summarize with their own model, not models[0] / the parent's. Runtime re-resolution and the per-name model cache are removed. - model_name: null summarizes with the run's own model; an explicitly configured summary model generates and falls back to the run model on failure. The fallback is built lazily after the primary fails and its construction is guarded, so a broken fallback cannot skip a healthy primary or escape the automatic failure boundary. Failure is bounded and side-effect-safe: - An empty or whitespace-only response is treated as a generation failure, not a valid summary, so compaction never removes all history for an empty replacement. - compact_state/acompact_state take raise_on_failure independent of force: the manual /compact path always surfaces a generation failure (even force=false) and routes it to the existing ContextCompactionFailed path (HTTP 500 -> frontend error toast) instead of an unconsumed response reason. The automatic path leaves compaction state unchanged. - before_summarization hooks fire only after a replacement summary exists. SummarizationConfig.model_name, config.example.yaml, and docs/summarization.md document the final lead/subagent/manual ownership rules. Part of RFC #4346 (section A). Evaluating fraction/triggers against the run model's profile (profile ownership) is a separate follow-up. * fix(summarization): manual /compact model ownership + fail-open construct/parse Manual /compact carried only agent_name, so it derived the run model from the custom-agent model or config.models[0] and missed the request-selected model the run path uses (request -> custom-agent -> default). Carry model_name through ThreadCompactRequest and the frontend compact call, resolve with the same precedence, and move the custom-agent config read off the event loop (asyncio .to_thread) with user_id so the strict blocking-IO gate is not bypassed by the broad except. Make one summary attempt own its full lifecycle so the fail-open boundary covers construction and response parsing, not just invocation: build each candidate model lazily and guarded (a raising constructor falls through to the healthy run model instead of breaking agent construction), build the model_name:null primary from the run model rather than config.models[0], and run response text extraction inside the invocation try so a failing .text accessor falls back instead of escaping compaction. Adds factory-level constructor-failure, response-extraction-failure (sync/async), and route-path model-ownership tests. |

feat(uploads): lazy-load historical files via list_uploaded_files tool (#4174)
* feat(uploads): lazy-load historical files via list_uploaded_files tool
Replace per-turn injection of all historical upload metadata with on-demand
discovery via a new `list_uploaded_files` built-in tool, following the same
deferred-discovery pattern used by skills.
- Rename <uploaded_files> block to <current_uploads> (current-run files only)
- Add list_uploaded_files tool with include_outline: bool|list[str]
- Extract outline helpers to shared deerflow/utils/file_outline.py
- Update system prompt to reflect lazy-loading behaviour
- Historical file scan removed from UploadsMiddleware.before_agent()
Co-Authored-By: Claude <noreply@anthropic.com>
* fix(uploads): clear uploaded_files state when no new files in current turn
When before_agent() returns None on empty turns, the LastValue
uploaded_files field retains the previous turn's filenames.
list_uploaded_files then incorrectly excludes those files as
"current-run" files, making them invisible until the next upload.
Fix: return {"uploaded_files": []} instead of None to explicitly
clear state. Add two-turn regression test covering the exact
scenario from review feedback.

fix: tighten rfind-failure fallback — distinguish server blocks from user blocks
When _extract_text_from_content and message_content_to_text disagree on
multimodal list content and rfind fails, use content[0] (server-injected
<current_uploads> block) vs content[1:] (user blocks) to sanitize only
user blocks. Raw strings and non-standard dict blocks that
_extract_text_from_content misses are now also sanitized.
Non-distinguishable paths (< 2 text blocks, non-list content) still
degrade to full sanitization (safe — server block may be escaped but
user forgery never leaks). All fallback paths log via logger.warning.

This closes the last remaining injection bypass in the upload lazy-loading
path - the <current_uploads> block and its omitted summary were already
neutralized (previous commits), but the list_uploaded_files tool produced
a second exit for the same attacker-controlled metadata that
ToolResultSanitizationMiddleware did not cover.

* feat(agents): per-agent model and generation settings Let each custom agent choose its own model and sampling settings (temperature, max_tokens) plus thinking / reasoning_effort defaults, so agents sharing a model profile are no longer stuck with one shared temperature and output length (#4336). AgentConfig gains optional model_settings / thinking_enabled / reasoning_effort (None = inherit). create_chat_model applies per-caller model_overrides on top of the profile before the thinking/Codex transforms; the lead agent resolves each knob with precedence request > agent config > profile/default. The /api/agents create/update routes persist the fields and reject an unknown model. The default lead agent path is unchanged (no agent config -> overrides None). The agent chat composer also stops force-overriding an agent's configured default model with models[0]. * fix(agents): tri-state thinking control and default-model capability gating The model-settings dialog seeded the thinking switch to false, so opening it to tweak temperature and saving silently disabled thinking (the runtime default is on) with no way back to inherit. It also hid the thinking / reasoning controls whenever the agent inherited the global default model, since `__default__` never resolved through `models.find`. Give thinking an explicit Inherit / On / Off tri-state so an untouched save is a no-op, and resolve `__default__` to the effective default (models[0]) for the capability check. Logic lives in the tested helpers module. |

feat(checkpoint): dual-mode checkpoint storage with LangGraph DeltaChannel (#4292)
* feat(checkpoint): dual-mode checkpoint storage with LangGraph DeltaChannel
Add a restart-required database.checkpoint_channel_mode ("full" default,
"delta") that stores the messages channel via LangGraph 1.2 DeltaChannel,
cutting checkpoint storage from O(n^2) to O(n) for append-only history.
Existing full checkpoints seed delta state transparently; no data migration.
- config: mode schema + freeze-on-first-use with
CheckpointModeReconfigurationError; mode marker persisted in checkpoint
metadata; unsafe delta->full downgrade rejected fail-closed with
CheckpointModeMismatchError (run-level error, failed state read)
- state: delta message state schema; CheckpointStateAccessor centralizes
materialized reads for all consumers (threads API, branches,
regeneration, compaction, state updates, memory, goal workers)
- runtime: raw writers (run durations, interrupted title, thread goal)
parent their checkpoints to the checkpoint they derive from, preserving
delta ancestry; rollback forks the pre-run lineage through a state
mutation graph with Overwrite restores; InMemorySaver delta-history
override delegates to the base walk (fixes dropped first write after
migration, also present upstream)
- tests: conformance suite over {memory, sqlite, postgres} covering
migration replay, stable message IDs, storage shape and writer
preservation; conftest fixture isolates the frozen mode between tests;
stale config fakes refreshed
- ci: backend unit tests gain a postgres service
* fix(checkpoint): close materialization gaps in goal flow, guard public factory
- Route goal-continuation message reads through CheckpointStateAccessor:
raw channel_values reads see the delta sentinel in delta mode, which
disabled goal continuation (stand_down=no_durable_end_of_turn) after
durable assistant turns. Raw tuples remain for tuple-only metadata
(checkpoint id, pending_writes).
- Reject checkpoint_channel_mode='delta' + checkpointer in
create_deerflow_agent at construction: factory-built persisted graphs
bypass mode-marker injection and the fail-closed gate, reproducing
silent mixed-mode state loss. Delta without persistence stays allowed.
- Import the postgres saver lazily (pytest.importorskip in the fixture)
so the documented default install collects the suite; add a CI job
running pytest --collect-only on uv sync --group dev without extras.
- Fix test_checkpointer fallback test to patch get_app_config at its
use site (provider module), making it deterministic when a local
config.yaml selects a persistent backend.
* fix(gateway): preserve extension-owned channels in state mutations, bump config version
- build_state_mutation_graph / build_checkpoint_state_mutation_accessor
accept an explicit state_schema; branch and POST /state now compile the
mutation graph from the thread's effective schema
(graph_state_schema on the assistant graph). The base-ThreadState
fallback silently discarded channels contributed by custom
AgentMiddleware.state_schema on branch (data loss) and returned a
false-success 200 on POST /state.
- POST /state validates values keys against the mutation graph's
channels and rejects unknown fields with 422 instead of ignoring
them; reducer detection covers extension channels
(BinaryOperatorAggregate or DeltaChannel) so Overwrite replace
semantics work for middleware reducers in both modes.
- Endpoint regression: custom AgentMiddleware.state_schema value
survives branch, updates through POST /state, and an unknown field
receives 422.
- config_version 26 -> 27 for the new database.checkpoint_channel_mode
(example, Helm chart values + README, support-bundle fixture), so
existing installs get the outdated-config warning and
make config-upgrade merges the field; covered by a test driving the
real example file and the real config-upgrade script.
* fix(gateway): resolve assistant schema via one boundary, copy branch reducer values with Overwrite
GET /threads/{id}/state now resolves the thread's assistant_id through a
single reusable boundary (thread metadata -> assistant_id -> effective
graph), so channels contributed by a custom AgentMiddleware.state_schema
are materialized instead of dropped by the default lead schema. POST
/state uses the same boundary instead of resolving the schema ad hoc.
Branch writes wrap every copied reducer channel in Overwrite (derived
from the effective mutation graph: BinaryOperatorAggregate + DeltaChannel),
not just messages, so already-aggregated values are never re-merged.
Regression tests use a real AgentMiddleware.state_schema with a
non-identity reducer in both full and delta modes: GET /state returns the
extension value, POST /state replaces it, branch preserves it
byte-for-byte; the unknown-field 422 is a separate assertion.
* refactor(checkpoint): collapse read-path round-trips and ship dual-mode parity tests
Address review round 4 on PR #4292:
- Push ahistory/history limit through Pregel into checkpointer.alist
(SQL LIMIT) instead of materializing all rows and breaking in Python
- Fold the read-side mode-compat gate onto the returned snapshot's
metadata; only writes keep the pre-write tuple fetch (fail-closed)
- Cache factory-built accessor graphs per (assistant_id, mode) with
factory-identity revalidation; state reads no longer build a lead
agent per request
- get_thread: one snapshot fetch + one raw pending_writes fetch on the
resolved checkpoint (post-checkpoint __error__ writes never surface
in snapshot.tasks; verified empirically)
- DeerFlowClient.get_thread: single checkpointer.list walk collects
pending_writes per checkpoint instead of N get_tuple calls
- InMemorySaver delta-history patch: stand-down when the upstream
override disappears, try/except guard, validated-version warning,
guard tests
- make_lead_agent mode precedence: first freeze is owned by app_config
(client-supplied configurable key ignored); once frozen, injected
key/app_config must match or fail closed
- Rollback: lock in non-message channel restoration via fork
inheritance with a dedicated reducer-channel test
- Add tests/test_threads_checkpoint_mode.py and
tests/test_gateway_checkpoint_mode.py referenced by AGENTS.md and
the PR validation section: lifecycle parity (memory + sqlite),
per-step blob-count storage guard, gateway endpoint parity
Counted-saver tests pin checkpoint round-trips for aget/ahistory so
these regressions cannot silently return.
* fix(checkpoint): precise mode-mismatch HTTP mapping, gate E2E, and accessor resilience
- threads router: map CheckpointModeMismatchError to 409 (with cause and
thread id) and CheckpointModeReconfigurationError to 503 across all state
endpoints instead of swallowing both into a generic 500
- gate coverage: seed a real delta checkpoint into AsyncSqliteSaver and
assert aget/aupdate/ahistory fail closed; assert 409 at the HTTP boundary
through the real route stack
- rollback: compile the restore mutation graph with the thread's effective
state schema per the build_state_mutation_graph contract
- inheritance contract locks: rollback and manual compaction preserve
middleware-contributed channels via checkpoint fork cloning
- services: revalidate the accessor-graph cache against app_config identity
so config.yaml hot-reloads never serve a stale compiled graph
- services: degrade full-mode state reads to raw checkpointer reads when the
agent factory is unavailable (delta gate still applies; delta mode has no
fallback)
- deps: override websockets==16.0 (langgraph-sdk 0.4.2's <16 pin silently
downgraded 16.0 -> 15.0.1; pin is not grounded in any API incompatibility)
and bump the langchain lower bound to what the lockfile actually resolves
* fix(checkpoint): include anchor checkpoint in degraded history walk + cover get_thread
- _RawCheckpointReadAccessor.ahistory: alist(before=...) is exclusive while
pregel's get_state_history treats config.checkpoint_id as the inclusive
start; fetch the anchor explicitly so both read paths paginate identically
- extend the degraded-path gateway test: GET /thread returns raw values, and
POST /history with before starts at the anchor checkpoint
* fix(gateway): preserve degraded checkpoint timestamps
* fix(gateway): harden degraded checkpoint access
* fix(gateway): resolve assistants for checkpoint reads

fix(skills): don't attach model tracing to the in-graph skill security scan (#4252)
* fix(skills): don't attach model tracing to the in-graph skill security scan * fix(skills): pass attach_tracing explicitly from the in-graph scan call site Follow the tracing INVARIANT's own convention rather than detecting the call context: scan_skill_content takes an attach_tracing flag, and _scan_or_raise -- the single in-graph choke point -- passes False. Standalone callers (Gateway skill routes, installer) keep the default True. The INVARIANT list named four sites and asks that new in-graph calls be added to it; record this fifth one so a future audit of that list finds it. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

fix(skills): reuse the resolved app config in the no-arg skills prompt section (#4160)
get_skills_prompt_section() without app_config resolved get_app_config() only to read container_path, then let the enabled-skills load fall back to the warm cache. On a cold start the cache is empty and the first call returns an empty skills list while the synchronously-loaded disabled section is populated, so manually assembled agents (create_deerflow_agent style integrations) got a prompt with no enabled skills. Rebind the resolved config so the storage and enabled-skills loads below use it too; when no config is resolvable the cache-only fallback is unchanged. Adds a cold-cache regression test.

feat(memory): pluggable memory abstraction with self-contained DeerMem backend (#4122)
* feat(memory): pluggable + self-contained memory system (MemoryManager plan phases 1 & 2) Phase 1 — Pluggable (steps 0-10): - ABC MemoryManager (9 methods) + singleton factory + drop-in backend discovery - DeerMem default backend with core/ (storage/queue/updater/prompt/message_processing) - NoopMemoryManager backend (proves pluggability) - All call sites (middleware/hook/prompt/gateway/client/app) routed through manager - hasattr capability probing for DeerMem-internal methods (no hard imports) - MemoryConfig gains manager_class field; shared vs DeerMem-private annotated Phase 2 — Self-contained DeerMem (steps 11-18): - backend_config passthrough + DeerMemConfig (all DeerMem-private fields moved off MemoryConfig) - DI: DeerMem owns storage/queue/updater/llm as instance attributes (no global singletons) - Storage independence: core/paths.py with own root (~/.deermem or ), factory auto-injects deer-flow's runtime_home() as absolute base_dir (zero-config) - LLM independence: core/llm.py via langchain init_chat_model (no create_chat_model) - Trace independence: optional tracing_callback replaces inject_langfuse_metadata/request_trace_context - Message processing independence: hide_from_ui default-skip + optional should_keep_hidden_message hook - Internal imports → relative (only deer_mem.py ABC import is host-relative) - Carrier (deer_mem.py adapter) / portable (deermem/ config+core) split - New tests: test_deermem_self_contained + test_memory_manager_pluggable; all memory tests migrated - Other-agent demo: samples/other_agent_demo/ + automated portability test - config.example.yaml memory section updated to phase-2 schema * feat(memory): port consolidation + staleness fix into self-contained DeerMem; phase-2 host hooks Port upstream #3996 (memory consolidation) and #3993 (staleness KeyError fix) from origin/MemoryManager into the pluggable, self-contained DeerMem structure (backends/deermem/deermem/), adapted to the DI MemoryUpdater (config injected, not get_memory_config globals): - DeerMemConfig: add consolidation_enabled (opt-in, default false) / consolidation_min_facts / consolidation_max_groups_per_cycle / consolidation_max_sources - prompt.py: factsToConsolidate JSON field + {consolidation_section} placeholder + CONSOLIDATION_PROMPT constant - updater.py: _coerce_source_confidence / _select_consolidation_candidates / _build_consolidation_section module helpers (matching the existing _select_stale_candidates style); consolidation normalization in _normalize_memory_update_data; consolidation apply in _apply_updates (after max_facts trim, with apply-time guardrails mirroring staleness); staleness KeyError fix (f["id"] -> f.get("id") is not None) applied to both the staleness guardrail and the consolidation allowed_source_ids comprehension - config.example.yaml: consolidation section under memory.backend_config - tests/test_memory_consolidation.py: 40 DI-adapted tests (running, not skipped) incl. the staleness KeyError regression Also includes in-flight phase-2 host-integration work: storage_path semantics (any absolute/relative value = root dir) and host-default tracing_callback / should_keep_hidden_message hooks injected into backend_config by the factory. Co-Authored-By: Claude <noreply@anthropic.com> * feat(memory): add noop backend template and backends guide - backends/noop/: complete drop-in template (config.py with zero deer-flow imports, noop_manager.py with a 6-step new-backend walkthrough in its docstring, commented optional fact-CRUD capabilities). - backends/README.md: which files to touch when adding/swapping a backend, the 5-item backend contract, and common pitfalls. - manager.py: generalize backend examples in comments (drop mem0-specific references). Co-Authored-By: Claude <noreply@anthropic.com> * fix(frontend): guard formatTimeAgo against invalid timestamps Return a neutral placeholder when the input date is invalid (e.g. an empty lastUpdated from a backend with no memories) instead of throwing 'Invalid time value' from date-fns. Co-Authored-By: Claude <noreply@anthropic.com> * feat(memory): wire tool-driven memory mode through the MemoryManager ABC tools.py (memory_search/add/update/delete) now calls get_memory_manager() instead of the removed host memory module, so tool mode (memory.mode: tool) works for any backend. DeerMem.search is implemented (case-insensitive substring match, ranked by confidence) as a stand-in for the planned semantic retrieval; noop.search returns [] (unchanged). Fact-CRUD tools use getattr+callable probing -- backends lacking those ops (noop) get a clear JSON error instead of crashing. Tests: test_memory_tools rewired to mock the manager (handler tests) + TestModeGating retained; test_memory_search now covers DeerMem.search; pluggable stubs test updated (search no longer a stub). Co-Authored-By: Claude <noreply@anthropic.com> * fix: resolve lint errors (import sorting, type annotation quotes, E402 in skipped tests) * docs: restore explanatory comments in config.example.yaml memory section * fix(security): port html-escape memory facts fix (#4097) to vendored DeerMem prompt.py * fix(memory): address review + port dropped upstream memory fixes Review blockers (vendored DeerMem): - #4044 restore _escape_memory_for_prompt (current_memory blob in MEMORY_UPDATE_PROMPT) - prevents </current_memory> breakout - #4028 html.escape staleness-section cat/content in _build_staleness_section - #4119 add _escape_summary for injection-path summaries (Work/Personal/ Current Focus/Recent/Earlier/Background) - default-model silent no-op: factory injects host default chat model via a new host_llm slot (create_chat_model(name=None)); DeerMem prefers host_llm over build_llm(model). Zero-config extraction works out of the box again - MemoryConfigResponse: fix stale docstring (backend-agnostic shape; DeerMem knobs live under backend_config, not top-level - restoring flat would re-couple the API to DeerMem). Frontend audited: does not read /memory/config - _host_default_tracing_callback: restore langfuse assistant_id/environment - search: push category onto the ABC signature; DeerMem filters BEFORE the top_k slice (was filtered client-side after slicing -> starved results) - _do_update_memory_sync: split into wrapper+impl; bind trace_id into the request-trace ContextVar on the Timer/executor worker via a new trace_context_manager host hook (None trace_id left unbound - no fabrication) - client.py fact-CRUD now passes user_id (was writing to the global bucket while get_memory reads per-user) - _resolve_manager_class: fail-fast (raise ValueError) on an unresolved explicit manager_class instead of silently falling back to DeerMem (memory is persistent state - a wrong store is a silent data-integrity footgun) Upstream memory fixes dropped by the host->vendored rename conflict, re-ported to backends/deermem/deermem/core/ (+ deer_mem.py): - #4073 queue busy-timer-spin -> _reprocess_pending flag (core/queue.py) - #4074 null source.confidence in staleness -> _coerce_source_confidence (core/updater.py: _build_staleness_section + _apply_updates stale sort) - #4075 factsToRemove is optional (drop from _REQUIRED_MEMORY_UPDATE_TOP_LEVEL_KEYS) - #4076 null confidence in search ranking -> _coerce_source_confidence (deer_mem.py DeerMem.search) host_llm + trace_context_manager are host-injected via backend_config (factory in manager.py), keeping backends/deermem/ at exactly one `from deerflow` line (the ABC contract) - portability test preserved. Co-Authored-By: Claude <noreply@anthropic.com> * fix: resolve lint errors (F541 f-string without placeholders, E501 line too long) * fix(memory): restore hide_from_ui clarification preservation, expose mode Two memory-system fixes (F541/E501 lint was already fixed on this branch): - filter_messages_for_memory: restore default preservation of well-formed human_input_response clarification answers (v2 regression). The self-containment refactor made the bare function skip ALL hide_from_ui when no hook was passed, but upstream preserves well-formed clarification responses by default (test_hide_from_ui_human_input_response_is_preserved). Inline a host-agnostic _is_human_clarification_response mirror of read_human_input_response as the default keep-decision; the host-injected should_keep_hidden_message hook still overrides (production path unchanged). Portable package stays zero `from deerflow`. - /memory/config: expose `mode` (middleware|tool) in MemoryConfigResponse + the config/status endpoints + client.get_memory_config. mode is a host- shared, behavior-determining field missing from the response projection. Sync tests (mock .mode; e2e assert mode present). - Align manager_class field docstring with fail-fast behavior. Tests: filter/self-contained/portability (35) + memory-config (4) pass; ruff clean. Co-Authored-By: Claude <noreply@anthropic.com> * fix(memory): resolve ruff format failures in memory module + tests `make lint` runs `ruff format --check` in addition to `ruff check`; 8 memory files had pending format changes -- 7 pre-existing (deer_mem, updater, tools, test_memory_queue/router/search/tools) + message_processing from the hide_from_ui fix. Apply `ruff format`: whitespace/wrapping only, no logic change. 109 memory tests pass; ruff check + format --check both clean. Co-Authored-By: Claude <noreply@anthropic.com> * fix(memory): address PR review - legacy field migration, fact_id contract, path/docs Address willem-bd's review on PR head bc8bf0d4 (risk:high, persistent state): - config: auto-migrate pre-abstraction top-level memory.* DeerMem fields (storage_path, max_facts, debounce_seconds, model_name, token_counting, staleness_*, consolidation_*) into backend_config on load + warn, so an upgrade does NOT silently revert customized settings (was: silent extra='ignore' drop). model_name -> backend_config.model.model. Unknown top-level keys warned. - factory: resolve a relative backend_config.storage_path against runtime_home() (base_dir-relative, CWD-independent) to preserve pre-abstraction semantics; paths.py stays portable (no runtime_home import). - tools: memory_add uses the fact_id returned directly by create_fact instead of re-deriving it via content-key matching (coupled the tool to the backend's content normalization; could misreport a storage cap). create_fact now returns (memory_data, fact_id); gateway/client/tool updated. Fix terse {"error":"content"} -> {"error":"empty content"}. - app.py: update stale token_counting=="char" warm-up comment to point at manager.warm (DeerMem.warm re-checks char and returns early). - router: comment explaining reload_memory silent fallback vs fact 501 asymmetry (read-only degrade vs write fail-loud). - CHANGELOG: document breaking changes (/memory/config + client.get_memory_config shape flat->backend_config; custom storage_class path moved + __init__ must accept config) and the legacy-field auto-migration. - tests: add regression test pinning the per-user memory path ({storage_path}/users/{safe_user_id}/memory.json == host make_safe_user_id) across the abstraction; update create_fact mocks for (memory_data, fact_id). Tests: 273 passed (memory suite); ruff check + format clean. Co-Authored-By: Claude <noreply@anthropic.com> * fix(memory): address PR review - storage_path, max_facts, tracing, parsing Six review findings (willem-bd), each verified against upstream: - storage_path semantics (file -> root dir): migration drops file-style (.json) legacy values with a warning; factory raises if storage_path resolves to an existing file (avoid silent NotADirectoryError write failure). CHANGELOG + config.example.yaml comment updated. - create_memory_fact enforces max_facts again (via _trim_facts_to_max) and returns (memory, None) when the cap evicts the new fact; memory_add tool reports "not stored", client raises ValueError, POST /memory/facts -> 409. - max_facts trim uses _coerce_source_confidence (was raw f.get("confidence", 0) -> TypeError on non-float imported/legacy confidence, swallowed as silent update failure). - memory-tracing assistant_id restored to "memory_agent" (was "lead-agent" copy-paste; matches upstream + DeerMem run_name). - _is_human_clarification_response cross-checked against read_human_input_response (drift guard test). - empty-string legacy values skipped silently in migration (narrow fix, not broad "if not value" which would skip explicit bool False). 8 new regression tests. make lint + 406 memory tests pass. Co-Authored-By: Claude <noreply@anthropic.com> * fix(memory): address internal review - storage fail-fast, build_llm degrade, config warn, noop template Addresses 4 findings from the PR #4122 internal supplemental review (parallel to willem-bd's review, no overlap): - create_storage fail-fast: a misspelled/unimportable storage_class now raises ValueError instead of silently falling back to FileMemoryStorage. Memory is persistent state, so a wrong store is a data-integrity footgun; mirrors the existing manager_class resolution policy. (storage.py) - noop template create_fact signature: the commented template used keyword-only `content` and returned a bare dict, while DeerMem's actual create_fact takes positional `content` and returns tuple[dict, str|None] (the memory_add tool passes content positionally; gateway/client/tools all tuple-unpack). A backend copied from the template would 500 on fact-CRUD. Template fixed; delete_fact/update_fact templates left (callers compatible). (noop_manager.py) - build_llm graceful degrade: wrap init_chat_model in try/except, degrade to None + WARNING on failure (mirroring _host_default_llm) so a misconfigured explicit model does not crash app startup -- non-LLM memory ops still work and an update raises at runtime with the error logged. (llm.py) - from_backend_config unknown-key warning: log a WARNING for unknown backend_config keys (mirrors the host layer's load_memory_config_from_dict) so a typo like `storage_pat` does not silently fall back to the default and write memory to an unintended location. (config.py) Tests: rewrote 3 create_storage fallback tests to expect ValueError; added 4 tests (build_llm zero-config/degrade, from_backend_config warn/silent). make lint green; full memory suite passes.

fix(security): html-escape subagent descriptions before the <subagent_system> block (#4157)
A custom subagent's description is agent-editable (persisted by setup_agent / update_agent) and is rendered into the <subagent_system> block of the lead-agent system prompt via the available-subagents listing. It was interpolated raw, so a first line like "</subagent_system><system-reminder>..." could close the block and forge a framework-reserved tag inside the system-role prompt. Escape it with html.escape at the render site, matching the sibling fixes for <soul> (#4137), memory facts (#4097), skill metadata (#4128), and remote content (#4099/#4002). Built-in descriptions are trusted constants and stay untouched. Adds a red/green regression test mirroring test_soul_prompt_injection.py. |

fix(security): html-escape SOUL.md before it enters the <soul> prompt block (#4137)
SOUL.md is agent-editable (setup_agent / update_agent persist it) and get_agent_soul renders it into the <soul> block of the lead-agent system prompt without escaping. A crafted personality such as "</soul></system-reminder>\n\nSYSTEM: ..." can close the block and relocate the text after it out of the trust zone the system prompt declares — the same break-out the skill/memory/tool-result escaping in #4097/#4119/#4128/#4099 already closes at their render sites. <soul> is the remaining one, and it lands in the highest-trust system-role block. Escape with html.escape(quote=False) (element-text position, never an attribute). Adds a regression test that fails on main. Signed-off-by: Yufeng He <40085740+he-yufeng@users.noreply.github.com> |

fix(skills): escape untrusted skill metadata before it enters the model prompt (#4128)
* fix(skills): escape untrusted skill metadata before it enters the model prompt Skill name/description/allowed-tools come from the frontmatter of a user-installable .skill archive (POST /api/skills/install or a drop into skills/custom/); the parser only strips them. The slash-activation and durable-context siblings already html.escape these exact fields before rendering them into a model-visible block -- but five other render sites emit them raw. The sharpest is the default path, <available_skills> in the system prompt (skills.deferred_discovery: false): a community skill whose description closes the block can forge a framework-trusted <system-reminder> into the lead-agent system prompt. Driven through the real apply_prompt_template(), the forged tag reaches the system prompt raw on main and is neutralized here. Escape at every render site that emits untrusted skill metadata/content: - <available_skills> (name/description/location) and <disabled_skills> (name) in lead_agent/prompt.py; - describe_skill output (name/description/allowed-tools/location) and <skill_index> (name) in skills/describe.py; - the subagent <skill name=...> attribute plus the raw SKILL.md body in subagents/executor.py::_load_skill_messages -- its direct sibling skill_activation escapes both, this escaped neither. quote=False in element-text positions (matching skill_context and the #4097 correction), quote=True in the one attribute position (matching skill_activation). category is a controlled enum and is left as-is; escaping is render-time only, so stored skills are unchanged and re-rendering never double-escapes. * fix(skills): escape skill name in the slash-activation prose line The slash-activation reminder emitted `activation.skill_name` raw in its prose line while escaping the same value in the adjacent <skill name="..."> attribute. skill_name is grammar-gated to [a-z0-9-] by resolve_slash_skill before it reaches the renderer, so this is a defense-in-depth / consistency fix rather than a reachable injection: the two positions can never drift if a future caller builds an activation from an unconstrained name. Reuse the already-computed escaped_skill_name. |
