feat(subagents): show effective model and token usage on task cards (#4049)
* feat(subagents): show runtime metadata on task cards

* fix(subagents): stop task-card render loop and dedupe model fetches

Address code review on the runtime-metadata cards:

- P1 render loop: the terminal ToolMessage is re-parsed on every
  MessageList render and always carries modelName/usage, so the
  presence-based setTasks condition fired a fresh state object each
  render -> "Maximum update depth exceeded". computeNextSubtask now
  returns a value-compared `changed` flag and a pure subtaskNotification()
  routes terminal transitions through the deferred after-render path
  while skipping no-op re-parses.

- Per-card useModels refetch: add staleTime: Infinity to the ["models"]
  query so every subtask card shares one /api/models fetch instead of
  refetching on each mount.

* make format

* refactor(subagents): dedupe token-usage validators + tidy event narrowing

Address PR review follow-ups:

- DRY: extract one shared token-usage validator per side. Backend
  status_contract.normalize_token_usage() now backs both the terminal
  ToolMessage metadata and the subagent.step/.end run events
  (step_events.py), and frontend messages/usage.normalizeTokenUsage()
  backs both the live task_running event (lifecycle.ts) and the terminal
  ToolMessage metadata (subtask-result.ts). Prevents the input/output/
  total_tokens validation from drifting across the four former copies.

- Nit: onCustomEvent narrows event.type once instead of re-checking the
  object shape per branch; the redundant task_started early-return
  (already validated by taskEventToSubtaskUpdate) is dropped.

fix(subagents): classify LLM error fallbacks as failed (#4042)
* fix(subagents): classify LLM error fallbacks as failed (#4041)

* fix(subagents): address #4042 review on LLM error fallback

- clarify _extract_llm_error_fallback docstring: tail-only scan is safe
  because subagents append their own terminal message, so the last
  AIMessage is never a stale parent-history marker (cross-ref worker.py)
- compute final_result and pop stop_reason only on the COMPLETED branch
  so the guard stop-reason pop no longer fires on the discarded FAILED path
- note the error_detail/"LLM request failed" fallbacks are defensive;
  the middleware always populates a non-empty content
- add regression test locking the stale parent-history marker invariant

fix(security): html-escape fact content in memory prompt sections (#4028)
* fix(security): html-escape fact content in memory prompt sections

Raw memory fact content was injected verbatim into prompt XML — a fact
containing a literal `"` could break the `"..."` delimiter, and a
closing tag like `</consolidation_candidates>` could prematurely end
the XML block, both potentially confusing the model.

Apply `html.escape()` to `content` in `_build_staleness_section` and
`_build_consolidation_section`, and to `cat` in the consolidation
section's XML attribute. Tests added for both sections covering special
characters, XML tag injection, and attribute injection.

Follow-up to #3996 as noted by reviewer willem-bd.

* fix(security): address reviewer follow-ups on html-escaping PR

- Escape `cat` in _build_staleness_section for symmetry with the
  consolidation section (both sections now consistently html-escape
  all LLM-derived category values that appear in the prompt)
- Add comment at current_memory=json.dumps() documenting the conscious
  accept: json.dumps leaves < > & unescaped; lower-risk than
  staleness/consolidation (read-only context, not delete/merge
  instructions); fix at fact-content insert time if revisited
- Add test for category escaping in the staleness section

* fix(security): reference tracking issue #4044 in conscious-accept comment

* style: compress conscious-accept comment to two lines

fix(subagents): inject durable context before compaction (#4040)
* fix(subagents): inject durable context before compaction

* fix(subagents): coalesce system messages after durable-context injection

Address #4040 review:
- append SystemMessageCoalescingMiddleware innermost on the subagent chain
  so the SystemMessage(authority) DurableContextMiddleware injects is merged
  into one leading system_message; otherwise the durable fix trades #4039's
  assistant-first 400 for a duplicate-system 400 on strict backends
- add a two-system regression guard driving the real builder output through
  a strict model; assert exactly one leading SystemMessage
- assert single-leading-system in the compaction integration test too
- update the middleware count/last-element assertion (coalescer is now
  unconditionally last, removing the summarization-dependence ambiguity)
- compare _skills_root against posixpath.normpath(container_path)
- document the coalescer on the subagent chain in backend/AGENTS.md

Fix circuit breaker wedging after a non-retriable half-open probe (#3991)
* Fix circuit breaker wedging after a non-retriable half-open probe

When the circuit breaker is half-open it admits a single probe call by
setting `_circuit_probe_in_flight = True`. If that probe raised a
*non-retriable* error (e.g. quota/auth), the except block skipped both
`_record_failure()` (correct - business errors must not trip the breaker)
and any probe reset, so the circuit stayed `half_open` with
`_circuit_probe_in_flight = True` permanently. Every later call then
fast-failed in `_check_circuit()` forever, because no call could run the
handler to reach `_record_success` / `_record_failure`.

Release the probe on the non-retriable path (mirroring the existing
GraphBubbleUp handler) so the next call admits a fresh probe. The breaker
still never trips on non-retriable errors. Applied to both the sync and
async paths.

Adds sync + async regression tests asserting the probe is released and the
next `_check_circuit()` re-admits a probe.

* Address review: extract _release_half_open_probe helper

Fix UnboundLocalError in memory injection when facts are empty (#3992)
`format_memory_for_injection` bound `facts_header` / `all_fact_lines` only
inside the `if isinstance(facts_data, list) and facts_data:` block, but the
structure-aware overflow-truncation path at the end of the function
references both unconditionally.

When a user's memory has sizeable user-context / history (so `sections` is
non-empty and the assembled output exceeds `max_tokens`) but an empty or
missing `facts` list, that block is skipped, so the truncation branch hits
`UnboundLocalError: cannot access local variable 'all_fact_lines'` and
aborts memory injection entirely.

Hoist the two initializers to function scope, alongside the existing
`guaranteed_line_tokens = 0`, so they are always bound. Behaviour is
unchanged when facts are present.

Adds a regression test (empty facts + oversized user context) that fails
with UnboundLocalError before the fix and truncates gracefully after.

Fix AttributeError in ThreadDataMiddleware when runtime.context is None (#3989)
`before_agent` guards `context = runtime.context or {}` at the top, but the
`run_id` stamp on a trailing HumanMessage still read the raw `runtime.context`,
so a None context (thread_id resolved from `config.configurable`) plus a
HumanMessage last message raised `AttributeError: 'NoneType' object has no
attribute 'get'`. Use the guarded local `context` instead.

Adds a regression test.

fix(sandbox): guard the reverse path-translation regex with a segment boundary (#4035)
* fix(sandbox): guard the reverse path-translation regex with a segment boundary

_reverse_output_patterns matches a mount's resolved local root with no
segment-boundary lookahead, unlike every other prefix match in this file: both
forward regexes carry one, and the three string-prefix resolvers compare against
`root + "/"`. Its optional trailing group needs a `/` or `\` to consume more, so
against a sibling that merely shares the prefix (".../skills-extra/data.txt") the
group matches empty and the regex still yields the bare root.

That extracted text then *equals* the mount root, which satisfies
_reverse_resolve_path's own `+ "/"` guard -- so the sibling is rewritten to
"/mnt/skills-extra/data.txt". Forward resolution refuses to map that back, so the
model is handed an absolute-looking container path it can never read. This runs
over every bash stdout/stderr and over read_file content.

Mirror _content_pattern's boundary class rather than _command_pattern's: this
regex sees arbitrary command output, where a root can legitimately be followed by
"," ":" or "\" -- all of which the shell-oriented class would reject, silently
dropping translations that work today. The trailing group keeps [/\\] so Windows
paths still match.

* test(sandbox): pin the end-of-output boundary that stops a host-path leak

The lookahead's `$` alternative had no test: deleting it left all 6866
backend tests green. It is not cosmetic. Output ending exactly at a mount
root -- printf '%s' "$PWD", a stripped last line, a capture truncated at
the buffer limit -- matches neither `/` nor `[^\w./-]`, so the pattern
fails and _reverse_resolve_paths_in_output emits the raw host path to the
model. main's unbounded pattern has no end-of-string problem; the
narrowing added here is what introduced the exposure.

Pin it: three prefixes, asserting both the container path and that the
host root is absent from the output. Deleting only `$` turns exactly
those three red.

Lift the boundary class and trailing group into named locals. The
compiled pattern is byte-identical; correctness hinges entirely on the
boundary class, so it should not sit at column 120 of a comprehension.

Fix KeyError in staleness review when a fact has no id (#3993)
The apply-time staleness guardrail built ``candidate_ids`` with a direct
``f["id"]`` access over ``_select_stale_candidates`` output:

    candidate_ids = {f["id"] for f in _select_stale_candidates(current_memory, config)}

Every other fact access in ``updater.py`` uses ``f.get("id")``; this was the
lone direct-subscript outlier. An aged, non-protected fact that lacks an
``id`` key — common in legacy / hand-edited / migrated ``memory.json`` — is a
valid staleness candidate, so it reached ``f["id"]`` and raised
``KeyError: 'id'``, aborting the entire background memory-update cycle for
that user. The guardrail runs unconditionally (independent of the
``staleness_review_enabled`` flag), so any id-less aged fact triggers it as
soon as the LLM returns a non-empty ``staleFactsToRemove``.

Skip id-less candidates when building the intersection set. They can never
be targeted by the id-based removal set anyway, so behaviour is otherwise
unchanged.

Adds a regression test with an aged, id-less fact that raises KeyError
before the fix and applies cleanly after.

fix(sandbox): scrub abbreviated *_PASS vars and Postgres PGPASSFILE from skill env (#4026)
* fix(sandbox): scrub abbreviated *_PASS vars and Postgres PGPASSFILE from skill env

env_policy blocks the full PASSWORD/PASSWD spellings but not the ubiquitous
abbreviated _PASS form (DB_PASS, SMTP_PASS, MYSQL_PASS, ...), whose value is the
plaintext password itself, so every skill subprocess inherited it. Postgres's
file-based credential sources PGPASSFILE (.pgpass locator) and PGSERVICEFILE
(pg_service.conf, may carry a password) were likewise missed -- the psql analog
of the MYSQL_PWD/REDISCLI_AUTH no-flag sources #4018 added.

Collapse *PASSWORD*/*PASSWD* into a single *PASS* pattern (which subsumes both,
covers the abbreviated family, and catches PGPASSFILE) and add PGSERVICEFILE to
the exact-name denylist. *PASS* deliberately does not touch PWD/OLDPWD, which
carry no PASS substring. Capability-handle vars (KUBECONFIG, DOCKER_CONFIG,
GIT_ASKPASS, ...) are a broader, non-value-bearing class and are left out of
this fix.

test_secret_like_names_are_blocked already pins the contract; the new names are
added to its parametrize list (red before, green after) and the benign-names
test guards against over-scrubbing PWD/OLDPWD.

* test(sandbox): pin the *_ASKPASS over-scrub that *PASS* introduces

*PASS* also matches the credential-helper vars GIT_ASKPASS, SSH_ASKPASS and
SUDO_ASKPASS, which main inherits. Each names a program whose purpose is to hand
the caller a credential, so inheriting the pointer is the same leak class as
inheriting the value -- a skill can simply invoke it. Scrubbing them is intended;
pin all three in test_secret_like_names_are_blocked (red on main) so the
behaviour is a decision rather than a side effect of the pattern's shape.

test_benign_names_are_allowed could not have caught this: none of its 14 names
carries a PASS substring, so it passes identically before and after the
broadening and asserts nothing about it. Record that in its docstring -- the
absence of a benign PASS-bearing name is a decision, and PWD/OLDPWD are the
boundary the list does pin.

Also note the incidental COMPASS_*/BYPASS_* over-scrub in the module comment
(over-scrubbing is this module's fail-safe direction; required-secrets is the
escape hatch), and list PGPASSFILE alongside PGSERVICEFILE in AGENTS.md.

feat(memory): add memory consolidation to synthesize fragmented facts (#3996)
* feat(memory): add memory consolidation to synthesize fragmented facts

When a fact category accumulates many individual entries, the LLM
reviews them during the normal memory-update call (same invocation,
no extra API cost) and decides whether groups of related facts can be
synthesized into a single richer fact. This completes the memory
lifecycle: extraction → guaranteed injection → staleness review →
consolidation.

- Select fragmented categories by min-facts threshold, surface the most
  fragmented groups first; prompt-layer caps aligned with apply-layer
  guardrails so the LLM never sees groups it cannot act on
- Cap consolidated confidence at source maximum to prevent inflation;
  reject results below fact_confidence_threshold
- Double-consume protection prevents a fact from being merged into
  multiple consolidation targets
- Feature-gated at both prompt and apply time with per-cycle safety caps
- Add 26 tests covering candidate selection, normalization, apply
  guardrails, and prompt integration

* fix(memory): address consolidation correctness issues from PR review

Six fixes based on maintainer review of #3996:

1. Deduplicate sourceIds in normalization — ["f1","f1"] previously
   bypassed the ≥2-distinct-sources check; dict.fromkeys collapses it
   to ["f1"] which is correctly rejected.

2. Run consolidation after max_facts trim — previously, sources were
   deleted then the merged fact could be evicted by the trim, leaving
   no record of either. Moving consolidation last ensures source facts
   exist in the post-trim index before removal.

3. Fix count= attribute in consolidation prompt — advertised the full
   category size but listed only max_sources IDs; now uses
   min(len(group), max_sources) to match what the LLM can act on.

4. Exempt staleness_protected_categories from consolidation candidates
   — mirrors the existing staleness-review contract so correction facts
   are never surfaced for merging.

5. Strip and default category in consolidation normalization — "  " or
   " preference " are now normalised, matching _normalize_memory_update_fact.

6. Propagate sourceError from source facts into consolidated fact —
   correction context is no longer silently lost on merge.

* fix(memory): add apply-time guardrails and tests for consolidation

P1: mirror the staleness-pass defense-in-depth pattern — build
allowed_source_ids from _select_consolidation_candidates at apply time
so a protected-category or below-threshold fact proposed by the LLM is
rejected regardless of model behavior.

P2a: test that LLM-returned confidence is capped at max source confidence
and that a capped result below fact_confidence_threshold is rejected.

P2b: test that factsToConsolidate with consolidation_enabled=False is a
no-op at apply time (35 tests, all pass).

* fix(memory): address three correctness issues from second review round

1. Default consolidation_enabled=False — consolidation is lossy (source
   content is permanently replaced, only consolidatedFrom IDs preserved);
   new lossy features default to off. config.example.yaml updated to match.

2. Unify confidence coercion between prompt and apply — _build_consolidation_section
   now calls _coerce_source_confidence(fact) instead of an inline 0.0-default
   coercion, so a null-confidence fact renders with 0.50 in the LLM prompt and
   is capped at 0.50 at apply time (same value, same function).

3. Preserve staleness clock on merge — consolidated fact now carries the
   newest source's createdAt (not now) so aged information does not gain a
   fresh staleness-review window just by being consolidated; consolidatedAt
   is added as an explicit audit field.

Three regression tests added (default=false, null-confidence consistency,
createdAt policy); all guardrail tests now set consolidation_enabled=True
explicitly so they test the guardrail, not the feature flag. 38 tests pass.

* fix(memory): harden createdAt comparison and confidence handling

1. createdAt max via _parse_fact_datetime — replaces string max() which
   crashes on non-string createdAt (numeric unix timestamps) and sorts
   Z/+00:00 mixed formats incorrectly. Mirrors how staleness computes age.

2. Remove dead min(..., 1.0) — _coerce_source_confidence already clamps
   each source confidence to [0, 1], so max(source_confidences) ≤ 1.0
   by contract; the outer min could never bind.

3. Clamp raw_llm_conf to [0, 1] before applying the source cap — out-of-
   range values like 1.5 are safe today (pinned by the cap) but defensively
   clamped first so the invariant holds even if the cap is ever loosened.

4. Doc: expand the apply-time guardrails comment to call out the protected-
   category exclusion via allowed_source_ids — this is the central safety
   property ("explicit user feedback is never silently merged away").

5. Test: add test_confidence_fallback_to_max_source_when_llm_omits_field
   covering the else-branch (LLM omits confidence → uses max_source_conf).

6. Fix lint: reorder imports in test file (stdlib before third-party).

39 tests, all pass.

fix(subagents): inherit summarization middleware and harden step capture (#3875 Phase 3) (#4009)
Phase 3 of #3875 — subagents previously inherited none of the lead's
context-compaction, so a deep-research subagent (max_turns up to 150)
could accumulate >1M cumulative input before max_turns/timeout/token_budget
engaged, even after Phase 2's budget capped the pathological tail.

- Gate the subagent runtime chain on the SAME ``app_config.summarization.enabled``
  switch the lead reads (per maintainer guidance in #3875), via the shared
  ``create_summarization_middleware`` factory. One config covers both chains;
  no separate ``subagents.summarization`` field. No-op when summarization is
  off (factory returns None).
- ``skip_memory_flush=True`` on the subagent path: the factory otherwise
  attaches ``memory_flush_hook`` (when memory.enabled), which flushes
  pre-compaction messages into durable memory keyed by thread_id. Subagents
  share the parent's thread_id, so without skipping the hook a subagent's
  internal turns would pollute the PARENT thread's durable memory
  (#3875 Phase 3 review point).
- Harden ``capture_new_step_messages`` to tolerate history contraction:
  summarization rewrites the messages channel via
  ``RemoveMessage(id=REMOVE_ALL_MESSAGES)``, shrinking len(messages) below
  the step-capture cursor. Without a reset, every step appended after the
  compaction point was dropped until length overtook the stale cursor (#3845
  interaction, maintainer validation point (a)). Cursor now resets to the
  new tail; id/content dedup prevents re-emitting pre-compaction steps.
- Couple the DEFAULT token-budget ceiling to ``summarization.enabled``
  (#3875 Phase 3 review point): 1M when compaction is on, 2M when off
  (preserves Phase 2's deliberate headroom for summarization-off
  deep-research runs that can exceed 1M). A user-set budget (global or
  per-agent) always wins regardless of the switch. Flagged tunable.

The summarization middleware does not implement ``consume_stop_reason``, so
the Phase 2 guard-cap stop-reason channel is unaffected.

Return the full-resolution image URL from image_search (#3990)
`image_search` set both `image_url` and `thumbnail_url` to the DDGS result's

though its docstring/usage_hint promise reference-quality images (and a result
with no `thumbnail` returned an empty `image_url`). DDGS `.images()` exposes the

fix(agent): snap tool-output tail forward so fallback truncation respects max_chars (#4017)
* fix(agent): snap tool-output tail forward so fallback truncation respects max_chars

_snap_to_line_boundary() moves an offset backwards to the preceding newline.
That is correct for the head's end offset, but _build_fallback() also applied it
to the tail's start offset, where moving backwards lengthens the tail. On output
whose last newline sits in the second half (log lines followed by one long
unbroken line: minified JSON, base64 artifacts), the returned string exceeded
max_chars by up to 17x, defeating the guard that exists to stop a single large
tool result from blowing the model context.

Add _snap_start_to_line_boundary(), the forward-snapping mirror, and use it for
the tail offset. The existing head_end guard becomes redundant because a forward
snap can only move the tail start away from the head.

test_result_never_exceeds_max_chars already asserted this invariant but passed
newline-free content, so the snapping branch was never exercised.

* test(agent): pin the forward-snap direction of the fallback tail

The bound test only asserts that the result fits max_chars. Its content has
no newline inside the tail's snap window, so _snap_start_to_line_boundary
returns pos unchanged and the test stays green even with the snap removed.

Place a newline in the window so the snap has to fire: the tail must begin
after it, which the pre-fix backward snap does not do.

feat(mcp): auto-promote deferred MCP tools from routing hints (#4019)
* feat(mcp): auto-promote deferred MCP tools from routing hints

When tool_search.enabled=true defers MCP tool schemas, PR1 routing hints
still require the model to spend a tool_search discovery round trip before
it can call the tool the routing metadata already points at. This adds a
McpRoutingMiddleware that matches the latest user message against PR1
routing keywords and promotes the matching deferred schemas before the
model call, removing that round trip.

Design (soft routing, opt-in, additive):
- Matches only the latest real HumanMessage (shared is_real_user_message
  helper, reused by SkillActivationMiddleware so the two cannot drift);
  case-insensitive substring match, no tokenizer dependency.
- Ordering: priority desc, then tool name asc; capped by the new global
  tool_search.auto_promote_top_k (default 3, clamped 1..5). Does not add or
  consume a per-tool auto_promote_top_k (PR1 schema unchanged); a per-tool
  value is ignored with a DEBUG note.
- Returns a plain {"promoted": ...} state update (not a Command) and relies
  on ThreadState.merge_promoted for union/dedupe, so auto-promote and a
  model-triggered tool_search converge on the same catalog hash.
- Installed before DeferredToolFilterMiddleware on every deferred-tool path
  (lead agent, subagent, embedded client, webhook via shared builders);
  a construction-time assert rejects the reversed order. catalog_hash is
  None / no routing index is a complete no-op, so bootstrap and ACP skip it.
- Privacy: never executes tools, never promotes policy-filtered tools, adds
  no routing keywords or matched tool names to trace metadata or INFO/WARN
  logs.

No behavior change when tool_search.enabled=false.

Tests: index construction, matching semantics, middleware state updates,
same-cycle deferred-filter interaction, lead/subagent/embedded-client
builder wiring + order invariant, config clamping, config.example.yaml
parseability, and privacy assertions.

* refactor(mcp): address auto-promote review nits

- executor: access app_config.tool_search.auto_promote_top_k directly to match
  the lead-agent and embedded-client paths (drop the over-defensive getattr that
  masked missing config); update the subagent test mock to carry tool_search.
- tool_search / mcp_routing_middleware: cross-reference the duplicated routing
  priority/keyword normalization between the builder and the middleware's
  defensive _normalize_index so they cannot silently drift.
- MCP_SERVER.md: document that auto-promote keyword matching is a case-insensitive
  substring test (not word-boundary), advising distinctive keywords.

* fix(sandbox): scrub MYSQL_PWD and REDISCLI_AUTH from the inherited skill env

env_policy blocks the MySQL and Redis connection strings (MYSQL_URL, REDIS_URL)
because they embed a password, but not the password variables the same clients
read directly: mysql/libmysqlclient takes MYSQL_PWD and redis-cli takes
REDISCLI_AUTH with no further configuration. Both names carry no
KEY/SECRET/TOKEN/PASSWORD/PASSWD substring, so they were inherited by every
skill subprocess -- the leak surface this module exists to close (#3861).

They need exact entries rather than a pattern: *PWD* would also strip PWD and
OLDPWD. REDIS_AUTH is included as the common non-canonical variant.

* Apply suggestions from code review

- Distinguish REDIS_AUTH (defensive, non-canonical) from MYSQL_PWD and
  REDISCLI_AUTH (documented no-flag credential sources) in the comment.
- Pin that request-scoped injection still overrides the host value for the
  newly blocked names, keeping required-secrets a working escape hatch.

- scripts/summarize_bench.py: JSONL aggregation with p50/p95/p99 tables
- bench_results.jsonl: 110 turns across 7 scenarios on real BoxLite 0.9.7

Key findings:

* perf(boxlite): skip health check for recently-released warm pool boxes

Boxes released within health_check_skip_seconds (default 5.0s)
are promoted directly without the ~14ms echo-ok round-trip.
A VM alive seconds ago is overwhelmingly likely to still be alive.

Add sandbox.health_check_skip_seconds config option.
Set to 0 to always health-check (old behaviour).

Benchmark (warm_same_thread, noop, 20 iters):
  acquire p50: 14.9ms → 0.0ms
  total p50:   29.9ms → 14.0ms

* chore: move benchmark scripts into backend/scripts/benchmark/

* fix: address BoxLite benchmark review findings

* fix(boxlite): only skip warm reclaim checks for released boxes

* fix(benchmark): keep BoxLite shim workaround off the event loop

* fix(boxlite): invalidate dead boxes from command path

* test(boxlite): cover skip window and invalidation edge cases

* fix(boxlite): treat sandbox-has-been-closed as terminal in _exec

* fix(boxlite): harden warm-pool reclaim and benchmark accounting

* fix(boxlite): validate warm-pool reclaims by default

* fix(config): expose boxlite health-check skip setting

* fix(boxlite): tighten failure classification and benchmark workaround

fix(security): neutralize prompt-injection tags in remote tool results (#4002)
* fix(security): neutralize prompt-injection tags in remote tool results

User input is already neutralized for framework/injection tags, but tool
results are not. Remote content fetched by web_fetch/web_search is equally
untrusted and can carry a forged <system-reminder> block that reaches the
model verbatim as authoritative context.

Extract a shared neutralize_untrusted_tags() primitive from
InputSanitizationMiddleware and apply it to remote-content tool results
(web_fetch/web_search/image_search) via a new ToolResultSanitizationMiddleware.
Local tool output (bash/read_file) is left untouched so legitimate code/file
content is never mangled.

* test: update subagent middleware count for tool-result sanitizer

The new ToolResultSanitizationMiddleware adds one entry to the shared runtime
chain (11 -> 12). Update the subagent count assertion, use a lazy import for
neutralize_untrusted_tags so the module loads even when tests stub the
input-sanitization module, and document the new middleware in AGENTS.md.

* fix(security): address review — sanitize bare str list items; document MCP scope

- Neutralize bare str elements inside a ToolMessage content list (previously
  only {type:text} dict blocks were rewritten), matching the str-in-list shape
  ToolOutputBudgetMiddleware._message_text already anticipates.
- Document the name-based allowlist limitation: MCP remote-content tools
  registered under arbitrary names (e.g. fetch_url) are not covered; a name
  heuristic is avoided to prevent mangling local tool output, with metadata
  tagging tracked as a follow-up. Add a regression test pinning this boundary.

fix(subagents): unify guardrail caps on additive stop_reason + add token_budget (#3875 Phase 2) (#3980)
Phase 2 of #3875. Two guardrail axes can end a subagent run early — the turn
budget (GraphRecursionError) and the token budget (TokenBudgetMiddleware) —
and both now surface *why* through one additive `subagent_stop_reason` field
instead of a status enum.

This completes and course-corrects Phase 1 (#3949), which shipped the
turn-budget cap as a `max_turns_reached` status enum. The agreed Phase 2
design replaces that enum with an optional `stop_reason` field
(token_capped | turn_capped | loop_capped): a new enum value would break v1
consumers, while an additive field is ignored by older frontends and ledger
readers. `max_turns_reached` and SubagentStatus.MAX_TURNS_REACHED are removed.

- subagents.token_budget config (default enabled, 2,000,000 tokens, warn 0.7)
  with per-agent override; TokenBudgetMiddleware is now attached in
  build_subagent_runtime_middlewares so the cost-ceiling backstop engages for
  every subagent. The hard-stop does not raise — it strips tool_calls and
  lets the run finish with a final answer, recording the cap on a per-run
  consume_stop_reason() accessor.
- executor.py: on normal completion it reads consume_stop_reason() and stamps
  completed + token_capped when the budget fired; on GraphRecursionError it
  recovers the last AIMessage partial (completed + turn_capped) or, if nothing
  usable survived, failed + turn_capped. SubagentResult gains stop_reason.
- status_contract.py / contracts/subagent_status_contract.json (v2) /
  frontend subtask-result.ts: additive subagent_stop_reason field, pinned by
  test_status_values_match_contract / test_stop_reason_values_match_contract.
- task_tool.py + delegation_ledger.py: drop the max_turns_reached paths; the
  ledger captures stop_reason and renders model-facing "capped" guidance so
  the lead reuses a capped completion knowingly.

The 2,000,000-token default is deliberately loose (tighten to taste) — it
would have roughly halved the reported 4.4M burn while leaving legitimate
deep-research runs (max_turns=150) room. Subagent summarization is a follow-up.

feat(frontend): render slash-skill activations as inline chips (#3981)
* feat(frontend): render slash-skill activations as inline chips

Show an explicit `/skill` activation as a compact inline chip in both the
composer and the chat transcript instead of raw slash text.

- Composer: selecting a skill suggestion stores it as a removable chip
  aligned inline with the textarea; the leading `/skill ` prefix is
  reattached only at submit time, so the backend activation protocol is
  unchanged. Backspace on an empty input or the chip's close button clears
  it; history navigation is disabled while a chip is active.
- Transcript: human messages that begin with `/skill` render the skill as a
  read-only chip followed by the task text.
- Add a shared `core/skills/slash.ts` (`parseSlashSkillReference` +
  `resolveSlashSkillDisplay`) mirroring the backend `slash.py` gate, so the
  transcript only shows a chip when the skill actually exists and is enabled.
  This removes a duplicated regex/reserved-name list and keeps display
  semantics consistent with backend activation.

Add unit tests for the shared slash parser and extend the chat e2e to assert
the composer still submits `/skill <task>` after showing a chip.

* chore(frontend): format chat e2e test

* refactor(skills): address slash-skill chip review feedback

Follow-up to the inline slash-skill chip PR, resolving three second-order
review findings:

- Drive the reserved-command set and skill-name grammar from a shared
  contracts/slash_skill_contract.json instead of a hand-copied
  "keep in sync" pair. slash.ts and slash.py now reference the fixture, and
  contract tests on both sides fail CI if either drifts.
- Extract a shared SlashSkillChip so the composer and transcript chips stay
  in lockstep, and normalize the off-scale /8 and /12 opacity steps to the
  standard /10 and /20 tokens.
- Split HumanMessageText into a pure parse gate plus a slash-only subtree
  that owns the useSkills() lookup, so a skill-enabled toggle no longer
  re-renders every plain-text human turn.

Verified: frontend eslint + tsc clean, pnpm test 572 pass (incl. new
slash-contract test); backend slash contract + slash-skills tests 31 pass.

* style(tests): sort slash skill contract imports

* fix(composer): inline the slash-skill text so the chip aligns with input

Address the "composer body layout change" review on #3981 by rendering the
active skill as an inline chip in the same text flow as the prompt, rather
than a separate flex row that drifted the box model across states.

- Render the chip + prompt inside one leading-6 wrapper and edit the prompt
  through a `contentEditable` span, so the chip sits inline with the first
  line and long/multi-line input wraps naturally back to the container edge.
- Align the chip with `align-top`: its h-6 (24px) height matches the text
  line height, so chip and first-line centers coincide exactly (measured
  delta 0), fixing the chip being raised above the baseline.
- Restore the placeholder in chip mode via a `data-empty` CSS `::before`,
  which also gives the empty editable span width so it is no longer treated
  as hidden.
- Widen the IME helper to `HTMLElement` and route the span's keydown/paste
  through the shared skill-suggestion, prompt-history, backspace-to-clear,
  and IME-composition handlers so contentEditable behaves like the textarea.
- Extend chat.spec.ts to drive the inline skill editor instead of the
  textarea after a chip is shown.

* style(frontend): fix composer class order formatting

* fix(composer): break long unbroken input inside the slash-skill row

The inline slash-skill editor wrapped with `break-words`
(overflow-wrap: break-word), which only moves an over-long token to the
next line before breaking it. A long unbroken string therefore started
on the line below the chip, and when the string contained a break
opportunity such as a hyphen the browser wrapped there and pushed the
remaining run to the next line, leaving a wide gap on the right.

Switch to `break-all` (word-break: break-all) so the text fills each
line from the chip and packs tightly regardless of hyphens or CJK.

feat: add composer input polishing (#3986)
* feat: add composer input polishing

* Revert "Merge branch 'main' into feat/input-polish"

This reverts commit 5b6ceccf0db3092bc62fde3b05e7816829601756, reversing
changes made to 45fbc57fef5fa5fd878cf0176c37f3e3bc7ebef6.

* Merge main into feat/input-polish

* style(frontend): format input helper polish guard

* fix(input-polish): address composer polish review findings

Frontend
- Add a cancel affordance to the in-flight polish status pill that calls
  abortInputPolishRequest(), so a slow/hung provider no longer hard-locks the
  composer for up to stream_chunk_timeout with a page reload (and draft loss)
  as the only escape.
- Reset promptHistoryIndexRef/promptHistoryDraftRef when a rewrite is applied
  (and on undo), so a stale history-browse index can no longer let the next
  ArrowDown silently overwrite the polished draft.
- Disable polishing while an open human-input card is present, matching the
  frontend/AGENTS.md rule that composer entry points defer to the card so
  card-reply metadata is preserved.
- canPolishInput now reuses parseGoalCommand/parseCompactCommand instead of a
  third hardcoded reserved-command regex, and drops the phantom /help entry
  (no /help parser exists in the composer), so future builtins only need to be
  taught to the existing parsers.

Backend
- Extract the non-graph one-shot LLM path (build model + inject Langfuse
  metadata + system/user invoke + text extract) into
  deerflow.utils.oneshot_llm.run_oneshot_llm, shared by the input-polish and
  suggestions routers so tracing-metadata and invocation shape cannot drift
  between the two copies.
- strip_think_blocks gains truncate_unclosed (default True, preserving the
  suggestions/goal JSON-prep behavior); input polish passes False so a draft
  that legitimately contains a literal <think> substring is no longer
  truncated into a partial rewrite or a spurious 503.
- Validate the empty-check and max_chars boundary against the same stripped
  view of the draft that is sent to the model, so the user-facing length
  boundary and the model input can no longer disagree.

Tests / docs
- Backend: literal-<think> preservation, whitespace-only rejection, and
  normalized-length/model-input agreement cases; suggestions tests repoint the
  create_chat_model patch to the shared helper module.
- Frontend: helper unit tests updated for the /help/reserved-command change; a
  new Playwright case covers cancelling an in-flight polish request.
- backend/AGENTS.md documents the shared one-shot helper and the polish
  normalization/think-tag behavior.

fix(mcp): synchronize session pool singleton lifecycle (#3797)
* fix(mcp): synchronize session pool singleton lifecycle

Parity follow-up to #3778 (skill storage) and #3730 (sandbox provider).
get_session_pool() already serialised creation with _pool_lock, but its
fast-path check and final return read the global separately, and
reset_session_pool() cleared it with no lock. A reset_mcp_tools_cache()
(reachable via the /api/mcp/cache/reset admin endpoint) racing a
concurrent get could null the singleton between the None-check and the
return, handing the caller None despite the -> MCPSessionPool annotation.

Build and return the pool inside _pool_lock with a double check, and
clear it under the same lock in reset_session_pool(). The critical
section is tiny and never awaits, so holding the threading.Lock is safe
from both the async and sync/worker-thread paths. No behavior change for
single-threaded callers.

feat(skills): Add native SkillScan phase 1 for skills (#3033)
* Add phase 1 skill static scanning

* Rework SkillScan phase 1 as native scanner

* refactor(skillscan): align phase 1 with trimmed RFC contract

- SecurityFinding: 7 fields (rule_id, severity, file, line, message,
  remediation, evidence); category/analyzer derive from the rule_id
  prefix, confidence/column/fingerprint/metadata removed
- scan_archive_preflight()/scan_skill_dir() are pure functions: no
  ScanContext, no policy schema; CRITICAL-blocks is a code constant and
  skill_scan.enabled is applied by enforce_static_scan()/callers
- secret-* evidence is redacted before findings leave the scanner
- de-dup keys on (rule_id, file, line) so repeated occurrences keep
  distinct locations for agent self-correction
- cloud-metadata detection consolidated into network-cloud-metadata
- nested zip members get a one-level stdlib magic-byte peek; an
  executable member escalates package-nested-archive to CRITICAL
- install metadata sidecar removed (Phase 7 decides if it is needed)
- rule specs moved next to their analyzers; skillscan/rules/ removed
- tests updated + new anchors: redaction, dedup lines, nested-zip
  escalation, single cloud-metadata rule, bundled-skill zero-CRITICAL

* fix(skillscan): tighten reverse-shell/secret/archive scan rules from review

Address PR #3033 review feedback on the native SkillScan analyzers:

- Reverse-shell false positives: split shell detection by signal strength
  (/dev/tcp/, nc -e stay CRITICAL; bash -i, mkfifo -> new HIGH
  shell-reverse-shell-heuristic, warn->LLM). The Python check is now
  AST-anchored on real socket.socket/os.dup2/subprocess call sites instead
  of raw-text substring matching, so prose/docstrings no longer hard-block.
- Secret evidence: _redact_secret_evidence returns [redacted] with no secret
  bytes (was value[:6], which leaked 2 real token bytes past the prefix).
- Archive DoS: cap outer archive member count (_MAX_ARCHIVE_MEMBERS=4096);
  scan_archive_preflight early-aborts with a package-too-many-members CRITICAL
  finding (routes through the existing blocked->400 fail-closed path).
- shell-destructive-command: broaden the rm -rf matcher to sensitive system
  roots (/home, /usr, /*, --no-preserve-root /) while leaving safe subpaths
  unflagged.
- Dead code: collapse _decode_text_for_analysis to a single decode path and
  drop the unused _TEXT_SUFFIXES set and _has_text_shebang helper.
- local_skill_storage: document why the host_path branch keeps app_config
  possibly-None (lazy kill-switch resolution; avoids eager get_app_config in
  config-free environments such as CI).

Tests: new negative/positive coverage in test_skillscan_native.py. Full
backend suite 6616 passed, 26 skipped.

feat(frontend):enhance the ask_clarification interaction with visualized card (#3956)
* feat(frontend): add structured human input cards for ask_clarification

Implement a reusable Human Input Card flow for ask_clarification while keeping
the existing text fallback for older clients and IM channels.

Backend:
- Add structured ToolMessage.artifact.human_input payloads for clarification requests.
- Preserve ToolMessage.content as the readable Markdown/text fallback.
- Normalize clarification options from native lists, JSON strings, plain strings,
  mixed scalar values, None, and missing options.
- Derive input_mode as choice_with_other when options exist, otherwise free_text.
- Keep disable_clarification non-interactive behavior as a plain ToolMessage with
  no human_input artifact.
- Cover artifact persistence and Gateway message metadata preservation in tests.

Frontend:
- Add human input protocol types, runtime guards, extractors, response builders,
  and thread-state helpers.
- Add reusable HumanInputCard with option buttons, free-text input, pending,
  read-only, disabled, and answered states.
- Render structured clarification cards from artifact.human_input, with Markdown
  fallback for malformed or legacy tool messages.
- Preserve line breaks in structured question/context/option text.
- Hide submitted clarification bridge messages from the chat UI via
  additional_kwargs.hide_from_ui.
- Send structured human_input_response metadata through the fourth sendMessage
  options argument, preserving run context in the third argument.
- Wire submissions for normal chats, custom agent chats, agent bootstrap chats,
  and sidecar chats.
- Derive answered state from raw thread.messages so hidden replies still update
  the original card.
- Clear pending state when the hidden reply arrives, dispatch is dropped, or a
  later async stream failure appears on thread.error.

* perf(frontend): optimize HumanInputCard UI interactions

- Support Enter key to submit text input (Shift+Enter for newline)
- Render question and context fields as Markdown instead of plain text
- Replace deprecated FormEventHandler type with structural typing

* test(frontend): add unit test cover optimize HumanInputCard UI interactions

* feat(frontend): disabled chatbox when has new human-input-card

* fix(style): lint error fix

* fix: sanitize hidden human input replies

- Preserve IME composition safety for human input card Enter submits
- Treat hidden human input responses as genuine user messages for sanitization
- Keep hidden card replies in memory filtering while excluding malformed/internal hidden messages
- Add regression coverage for card IME handling and hidden reply sanitization

* fix: tighten human input response validation

- Reject empty hidden human input response values
- Remove invalid list ARIA role from human input card options
- Add backend coverage for empty response payloads

feat(middleware): add structured tool result meta and tool-progress state machine (#3601)
* feat(middleware): add structured tool result meta and tool-progress state machine

feat:
- Add tool_result_meta.py: ToolResultMeta dataclass (status/error_type/retryable/
  recoverable_by_model/recommended_next_action/source) + normalize_tool_result and
  stamp_exception_meta utilities; classifies every ToolMessage regardless of path
- Add ToolProgressMiddleware: per-(thread_id, tool_name) state machine ACTIVE →
  WARNED (hint injected as HumanMessage) → BLOCKED (call short-circuited); Jaccard
  near-duplicate detection for repeated successful results; auth/config/internal
  errors bypass WARNED and go directly to BLOCKED; LRU-bounded thread state store
- Add ToolProgressConfig: all thresholds configurable (stagnation_threshold,
  warn_escalation_count, jaccard_similarity_threshold, exempt_tools, etc.);
  disabled by default (enabled: false)
- Wire ToolProgressMiddleware as outer wrapper around ToolErrorHandlingMiddleware
  in _build_runtime_middlewares so it receives results already carrying
  deerflow_tool_meta

fix:
- ToolErrorHandlingMiddleware now calls stamp_exception_meta on exception path and
  normalize_tool_result on success path so every ToolMessage carries deerflow_tool_meta

test:
- Add test_tool_result_meta.py: 26 cases covering all classification paths,
  stamp_exception_meta, and normalize_tool_result Command passthrough
- Add test_tool_progress_middleware.py: 27 cases including full async paths,
  Jaccard duplicate detection, LRU eviction, hint injection, and malformed meta
  passthrough
- Extend test_tool_error_handling_middleware.py: middleware ordering invariant and
  meta stamping on exception

docs:
- Add tool_progress section to config.example.yaml with all fields and descriptions
- Update CLAUDE.md middleware chain documentation (entries 8-9)

Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>

* fix(middleware): recoverable errors stay WARNED; fix auth keyword shadowing

fix:
- WARNED is terminal for recoverable_by_model=True errors (no_results, not_found,
  permission); hint re-injected on each problem call instead of escalating to
  BLOCKED, so the model can retry with different parameters (e.g. fresh query,
  new URL) without being hard-blocked by a prior stagnation count.
  Non-recoverable (rate_limited, transient) still escalate WARNED → BLOCKED
  after warn_escalation_count more problems; auth/config/internal remain
  immediately BLOCKED.
- Remove bare "api key" keyword from auth classification rule so "no api key
  configured" correctly classifies as config (not auth), producing the accurate
  block-reason text for the model.

docs:
- CLAUDE.md: document all three ToolProgressMiddleware transition paths
- config.example.yaml: update inline state-machine comment to match new paths

test:
- test_recoverable_errors_stay_warned_indefinitely: WARNED never escalates for
  recoverable errors regardless of how many problem calls accumulate
- test_recoverable_error_re_injects_hint_past_escalation: hints continue past
  the escalation zone for recoverable errors
- test_no_api_key_is_config_not_auth: regression guard for keyword shadowing fix

* fix(tool_result_meta): add JSON error extraction and fix source classification

fix:
- Fix non-standard error path: source was "exception" but should be "tool_return"
- Add _extract_json_error_text to isolate JSON error fields from noisy JSON bodies
  (e.g. Brave Search {"error": "...", "query": "..."} — query keywords no longer
  pollute error classification)
- Add success-path JSON extraction to catch tools that return HTTP 200 with a JSON
  error body (status="success" but {"error": "API key not configured"})
- Add _SEMANTIC_ZERO_ERROR_STRINGS frozenset to suppress false positives from tools
  that use {"error": "none"} / {"error": "null"} / {"error": "ok"} as success signals
- Document that stamp_exception_meta always overwrites existing TOOL_META_KEY
  (exception-derived classification is authoritative over tool return-time stamps)

test:
- Add parametrized regression tests for all semantic-zero error strings
- Add tests for non-standard error path source field
- Add tests for JSON error extraction (nonstd, success-path, numeric, falsy values)
- Correct test comment for test_no_api_key_is_config_not_auth

* fix(tool_progress_middleware): fix 6 bugs, add terminal guard and structured logging

fix:
- H1: fix exempt_tools empty-set silently ignored — use `is not None` instead of
  truthiness check so ToolProgressConfig(exempt_tools=set()) correctly disables all
  exemptions
- Fix _get_block_reason creating phantom LRU entries via _get_state (write path);
  now uses dict.get + explicit move_to_end on read path only
- Fix _pending memory leak: LRU eviction of _phase_states now synchronously removes
  all (evicted_thread, *) keys from _pending
- Fix _assess_and_transition missing terminal guard for blocked state — a recoverable
  error result could silently demote blocked → warned in concurrent-race scenarios;
  early return preserves terminal semantics
- Fix recent_word_sets window: stored [-5:] but is_near_duplicate only compared [-3:];
  align to [-3:] and change type list→tuple (prevents accidental in-place mutation
  across dataclasses.replace shallow copies)
- Fix _format_hint missing "success" key and "continue" action: Jaccard near-duplicate
  results produced the generic fallback instead of a specific actionable message

feat:
- Add structured state-transition logging (ACTIVE/WARNED/BLOCKED transitions, blocked
  intercepts, hint injection debug log)

test:
- Add regression tests for all 6 bug fixes (H1, phantom LRU, pending leak, terminal
  guard, window alignment, format_hint near-dup)
- Add Jaccard near-threshold boundary test (7/9 vs 8/9 Jaccard)
- Add production min_words=10 skip test for short content
- Add exempt_tools empty-set and None round-trip tests
- Add _augment_request deduplication test
- Add before_agent current-run preservation test
- Add structured logging tests (WARNED/BLOCKED/ACTIVE/intercepted/debug)

  permanently warm in LRU, starving active threads of eviction slots
- Add _reset_blocked_states in before_agent: scope BLOCKED and WARNED states
  to a single run; clear recent_word_sets so stale Jaccard windows don't cause
  false near-duplicate detections in the next run
- Compute word_set() lazily (only for success results); cap content at 8192
  chars to bound memory and CPU cost on large tool results
- Remove unused retryable field from ToolResultMeta (no consumer existed)
- Add isinstance-based ordering guard and warning log for missing meta
- Fix JSON-without-error-key fallback: use _UNKNOWN_ERROR instead of
  classifying incidental field values (e.g. {"user_id": 401} → auth → stop)
- Fix _extract_json_error_text: use json.dumps for dict/list error fields
  instead of str() which produced Python repr matching config rules spuriously
- Add "no results found"/"no content found"/"no images found" to _PARTIAL_MARKERS
  so success responses with empty results trigger stagnation detection
- Fix immediate-block path to increment consecutive_problems (was left at 0)
- Fix _queue_assessment: skip phantom _pending entries for evicted threads
- Bump config_version 13→16 (upstream added 14/15; tool_progress is additive)

test:
- Update test_short_content_is_partial → test_short_terse_success_is_not_partial
- Add parametrized test_numeric_keyword_word_boundary (8 positive + negative cases)
- Add test_before_agent_resets_blocked_states_for_new_run (strengthened assertions)
- Add test_before_agent_resets_warned_states_for_new_run
- Add test_missing_meta_on_non_exempt_tool_emits_warning
- Add test_middleware_ordering_guard_raises_when_progress_is_inner
- Add test_auth_error_immediately_blocked asserts consecutive_problems == 1
- Add tests for JSON-without-error-key, dict error field, no-results partial_success

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

* fix(tool_progress): address second PR review — perf, architecture doc, concurrency note

fix:
- Extract content.lower() once before _PARTIAL_MARKERS check in normalize_tool_message;
  previously computed up to 7× per call inside the generator (once per marker)

docs:
- Add division-of-labor paragraph to ToolProgressMiddleware module docstring explaining
  coexistence with LoopDetectionMiddleware: result-quality guard (per-tool BLOCK) vs
  call-pattern guard (whole-turn hard-stop); no shared state, no double-stop risk
- Add threading.Lock comment explaining why asyncio.Lock is not used (short critical
  sections, must also protect sync wrap_tool_call path from subagent executor threads)
- Update backend/CLAUDE.md entry 8 with division-of-labor summary; fix entry 9
  (remove stale retryable field reference, add missing recoverable_by_model/source)

test:
- Add test_tool_progress_and_loop_detection_coexist_without_interfering: drives both
  middlewares to WARNED state simultaneously, verifies independent state, independent
  hint queues, and no cross-contamination; uses snapshot copy for final assertion

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

* fix(tool_progress): reset all tool states at run boundary; fix semantic-zero test validity

fix:
- _reset_run_states (formerly _reset_blocked_states) drops the phase filter and
  resets all tracked (thread, tool) pairs unconditionally at before_agent; ACTIVE
  tools with sub-threshold consecutive_problems or cached recent_word_sets no longer
  bleed into the next run, preventing spurious WARNED transitions on clean R2 calls
- test_normalize_json_semantic_zero_error_string_not_treated_as_error: replace
  {error_value!r} f-string (produces invalid JSON with single quotes) with
  json.dumps so _extract_json_error_text actually parses the payload and the
  _SEMANTIC_ZERO_ERROR_STRINGS guard is exercised, not bypassed at json.loads

test:
- add test_before_agent_resets_active_state_consecutive_problems_and_word_sets to
  lock the ACTIVE-phase run-boundary reset: drives tool to active/cp=1/ws≠() in R1,
  asserts both fields are zero/empty after before_agent fires for R2

* docs(tool_progress): document intentional per-run reset vs LoopDetection thread-scoped retention

Addresses reviewer observation in PR #3601 that _reset_run_states diverges
from LoopDetectionMiddleware's cross-run scoping policy without explanation.

Expands the _reset_run_states docstring to record the intentional design
choice: ToolProgressMiddleware resets per-run because result-quality errors
(rate_limited, transient) are time-bound and may resolve between turns —
retaining stale counters would risk false-positive BLOCKED calls.
LoopDetectionMiddleware retains history across runs because call-pattern
loops are time-invariant. The divergence is by design, not oversight.

* fix(middleware): restore ReadBeforeWriteMiddleware as outermost write gate

A merge conflict resolution had accidentally placed ReadBeforeWriteMiddleware
after ToolErrorHandlingMiddleware (inner), reversing the original intent from
b81334cc where it was the outermost write gate before ToolErrorHandling.

fix:
- Restore ReadBeforeWriteMiddleware to outer position: ReadBeforeWrite →
  ToolProgress → ToolErrorHandling. Blocked writes now return immediately
  without consuming a ToolProgress slot.
- Add normalize_tool_result call on blocked ToolMessages so they carry
  deerflow_tool_meta (recoverable_by_model=True) even though they bypass
  ToolErrorHandlingMiddleware.

test:
- Add test_blocked_write_has_deerflow_tool_meta (sync + async) to lock the
  normalize_tool_result behavior on blocked writes.
- Fix chain order assertions in TestChainWiring and
  test_build_lead_runtime_middlewares_chain_order_matches_agents_md.

docs:
- Renumber AGENTS.md items: 10→ReadBeforeWrite, 11→ToolProgress,
  12→ToolErrorHandling; update descriptions to reflect outermost-gate design.
- Fix stale cross-reference: LoopDetectionMiddleware (item 23) → (item 25).

feat(memory): add staleness review to prune silently-outdated facts (#3860)
* feat(memory): add staleness review to prune silently-outdated facts

Facts created long ago may become outdated without any future conversation
explicitly contradicting them ("Silent Staleness").  This adds a staleness
review mechanism that surfaces aged facts to the LLM during the normal
memory-update call so it can semantically judge whether each is still valid.

- New MemoryConfig fields: staleness_review_enabled, staleness_age_days,
  staleness_min_candidates, staleness_max_removals_per_cycle,
  staleness_protected_categories
- New STALENESS_REVIEW_PROMPT section injected into MEMORY_UPDATE_PROMPT
  when enough stale candidates exist
- New staleFactsToRemove output field in the LLM response schema
- Safety cap limits max removals per cycle, keeping lowest-confidence
  entries when the LLM returns more than the cap
- Correction facts (category=correction) are protected by default
- Observability via structured logging of each removal with reason
- 32 unit tests covering parsing, selection, triggers, formatting,
  normalization, safety cap, and integration

* fix(memory): add deterministic guardrail for staleness removals

_apply_updates previously removed any fact id the LLM returned in
staleFactsToRemove without verifying it was in the actual staleness
candidate set.  An LLM slip could silently delete protected-category
facts (e.g. correction) or fresh facts, defeating the stated guarantee.

Now intersect stale_ids_to_remove with _select_stale_candidates before
the safety cap, making the protection independent of both model behavior
and the staleness_review_enabled flag.

Add three regression tests:
- test_protected_category_fact_refused_at_apply
- test_non_aged_fact_refused_at_apply
- test_guardrail_runs_when_staleness_review_disabled

* docs(memory): sync AGENTS.md staleness config + simplify datetime parsing

Address reviewer feedback from PR #3860:
- Add staleness workflow step and 5 new config fields to backend/AGENTS.md
- Simplify _parse_fact_datetime: drop manual Z→+00:00 replace, Python 3.12+ fromisoformat handles Z natively

fix(subagents): surface turn-budget cap as MAX_TURNS_REACHED with partial result (#3875 Phase 2) (#3949)
* fix(subagents): surface turn-budget cap as MAX_TURNS_REACHED with partial result (#3875)

Phase 2 of #3875. When a subagent exhausts its turn budget
(recursion_limit == max_turns), LangGraph raises
GraphRecursionError from agent.astream. The generic
except Exception in _aexecute misclassified it as FAILED and
discarded the partial work already streamed into final_state, so the
lead could not tell 'broken subagent' from 'out of budget' and got an
empty failure.

Catch GraphRecursionError specifically (before the generic handler)
and set a distinct SubagentStatus.MAX_TURNS_REACHED terminal status,
recovering the partial result from the last streamed chunk via a shared
_extract_final_result helper (refactored out of the normal-completion
path so both paths render content identically).

Extend the cross-language status contract so the new value travels on
additional_kwargs.subagent_status: a capped run is result-bearing, so
make_subagent_additional_kwargs / read_subagent_result_metadata
carry subagent_result_brief + subagent_result_sha256 (the
recovered work, like completed) AND the cap notice on subagent_error
-- the one status that carries both. task_tool.py returns it via the
shared _task_result_command; the delegation ledger prefers the
partial result_brief and renders model-facing guidance (reuse / retry
tighter / raise max_turns). Frontend collapses max_turns_reached to the
failed pill with the cap notice on error.

No agent-loop, runner, or persistence behavior touched; default
max_turns is unchanged.

* refactor(subagents): consolidate content-stringify onto shared helper

Address review feedback on #3949 (willem-bd, copilot-pull-request-reviewer):

- executor.py: drop the private `_stringify_message_content` — a third
  near-duplicate of `utils/messages.py::message_content_to_text`.
  `_extract_final_result` now delegates to that canonical helper; the
  "No response generated" sentinel is pushed down to the consumer (the
  shared helper returns "" for no-text, matching every other call site).
- task_tool.py: align the live `task_failed` event's error string with
  the canonical "Reached max_turns=N" used by the logger, the structured
  `error=`, and the executor (was "Reached max turns (N)").

Behavior for real AIMessage content is unchanged; only atypical edge inputs
(consecutive bare-string list items; empty content) now match the canonical
helper that every other call site already uses.

`extract_response_text` is intentionally left as-is: it filters by OpenAI
content-block `type`, a different shape with many callers and its own tests.

feat(sandbox): warm pool for boxlite (#3951)
* feat: add boxlite SDK as harness dependency

* test: add fake SimpleBox fixtures for BoxLite warm pool tests

* feat: add deterministic sandbox_id and warm pool fields to BoxliteProvider

* feat: pass deterministic sandbox_id to SimpleBox name

* feat: warm pool lifecycle — park on release, reclaim on acquire

- release(): parks VMs in _warm_pool with timestamp instead of closing
- _reclaim_warm_pool(): health checks warm boxes via echo ok
- acquire(): tries warm pool reclaim before creating new boxes
- Deterministic sandbox_id ensures thread isolation

* feat(boxlite): idle reaper, replica enforcement, warm-pool shutdown/reset

- Task 6: idle reaper daemon thread destroys expired warm-pool boxes
- Task 7: replica enforcement evicts oldest warm-pool box when at capacity
- Task 8: shutdown() stops idle checker first, destroys all boxes (active+warm);
  reset() clears warm pool

Tests: 17 passed (4 new: idle reaper, replica enforcement, shutdown, reset)

* fix(boxlite): harden warm pool lifecycle races

* docs(boxlite): document warm pool configuration

* fix(sandbox): log warning when evicting oldest warm box is failed

Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

* fix(boxlite): stop provider lifecycle on reset

* fix(boxlite): make runtime an optional dependency

* test(boxlite): remove unused warm pool lookup

* docs(boxlite): clarify optional runtime support

* refactor: extract shared WarmPoolLifecycleMixin for sandbox warm-pool lifecycle

Introduce deerflow.community.warm_pool_lifecycle.WarmPoolLifecycleMixin
owning idle-checker loop, warm-pool expiry, oldest-warm eviction,
replica counting, and soft-cap logging. Move AioSandboxProvider and
BoxliteProvider onto the mixin; keep AIO active-idle cleanup local and
delegate only warm-pool expiry to the shared helper.

BoxliteProvider also gains:
- Prefixed box names (deer-flow-boxlite-*) for startup orphan reconciliation
- _reconcile_orphans() adopting surviving boxes from a prior process
- Pinned timeout forwarding: command timeout now bounds both BoxLite
  SDK exec(timeout=...) and the loop bridge .result(timeout)
- reset() reworked as lightweight registry clear (boxes -> warm pool,
  no close, no idle-reaper stop, no loop close) so reset_sandbox_provider()
  config switches are safe; shutdown() remains the teardown path

Backward-compatible: AIO DEFAULT_IDLE_TIMEOUT/DEFAULT_REPLICAS/
IDLE_CHECK_INTERVAL stay importable; Boxlite IDLE_CHECK_INTERVAL
stays monkeypatchable.

fix(models): normalize api_base->base_url for ChatOpenAI + warn on unknown config keys (#3790)
ModelConfig is `extra="allow"`, so a config key like `api_base` (which
config.example.yaml uses for other model classes, e.g. PatchedChatDeepSeek and
Moonshot) gets copied onto a `langchain_openai:ChatOpenAI` model by users.
LangChain's OpenAI client does not reject the unknown kwarg — it transfers it
into `model_kwargs` (with a UserWarning), which is then spread into every
`Completions.create()` call and rejected by the OpenAI SDK at REQUEST time with
an opaque `unexpected keyword argument 'api_base'` error. The endpoint override
is also silently dropped, so the model targets the wrong base URL.

Changes in factory.py, mirroring the existing OpenAI-compatible helpers:

- `_normalize_openai_base_url`: renames `api_base` -> `base_url` for the
  OpenAI-compatible family (ChatOpenAI + PatchedChatOpenAI); when an endpoint
  key is already present, drops the alias with a warning. Runs before the
  stream_usage/stream_chunk_timeout heuristics so they see the canonical key.
- `_warn_unknown_model_settings`: scoped to the same OpenAI-compatible family
  (where the model_kwargs divert-and-crash actually happens and the field/alias
  set is accurate), logs an actionable warning for unrecognized config keys.
- The three OpenAI-compatible helpers now share `_OPENAI_COMPAT_USE_PATHS`
  instead of disagreeing on the literal class string.

Adds a note to docs/CONFIGURATION.md and 9 tests covering normalization
(ChatOpenAI + PatchedChatOpenAI, both-set precedence for base_url and
openai_api_base, non-OpenAI class untouched, no-op when unset) and the
unknown-key warning (fires on a typo, silent on a clean config and on
non-OpenAI providers like ChatAnthropic).

feat(sandbox): add BoxLite micro-VM sandbox provider (scaffold) (#3940)
* feat(sandbox): add BoxLite micro-VM sandbox provider (scaffold)

Community SandboxProvider backed by BoxLite, a daemonless OCI-native micro-VM
runtime. execute_command is wired end to end through a private asyncio loop that
bridges BoxLite's async SDK to DeerFlow's sync Sandbox contract; the remaining
Sandbox methods are stubbed pending approach review. Opt-in via sandbox.use
(pip install boxlite); a packaged [boxlite] extra will follow. Existing
providers are unchanged.

Refs #3936, #3439, #3213

* feat(sandbox): implement full Sandbox contract for BoxLite backend

Rename the community BoxLite integration to read as a compute backend rather
than "a sandbox": module boxlite_sandbox -> boxlite, BoxliteSandboxProvider ->
BoxliteProvider, BoxliteSandbox -> BoxliteBox.

Implement the file surface DeerFlow's default tool path assumes -- read_file,
write_file, update_file, download_file, list_dir, glob, grep -- as shell
commands inside the box (cat/find/grep/chunked base64), reusing
deerflow.sandbox.search and busybox-portable flags. Removes the reachable
NotImplementedError regression once the provider is selected. download_file
keeps the /mnt/user-data prefix + traversal guards; the provider materialises
those virtual dirs on box start.

Refs #3936, #3940

* fix(sandbox): resolve CI + review findings on BoxLite backend

- provider: import DEFAULT_SKILLS_CONTAINER_PATH instead of the "/mnt/skills"
  literal (backend-unit-tests guard), and drop the redundant env-var
  re-resolution -- AppConfig.resolve_env_variables already resolves $VARS and
  raises on missing.
- box: grep now passes the raw pattern to grep (-F/-E); it previously handed
  the re.escape'd pattern to grep -F, so a literal search of e.g. foo.bar
  looked for foo\.bar and never matched.
- box: execute_command now calls _validate_extra_env(env), matching the
  Sandbox POSIX env-key contract that the local/e2b/aio sandboxes enforce.
- add tests/test_boxlite_provider.py (CI-safe, no BoxLite): actionable
  ImportError on the lazy import, clean acquire-failure + shutdown, the
  traversal / download-prefix guards, and env-key rejection.

fix(langfuse): resolve trace user from runtime context (#3794)
* fix(langfuse): resolve trace user from runtime context

The worker built langfuse_user_id from get_effective_user_id(), which reads
the request-scoped _current_user ContextVar. For runs invoked over an
internal token on behalf of an end user, that ContextVar is never the end
user, so traces recorded langfuse_user_id="default".

Switch to resolve_runtime_user_id(runtime), matching the sandbox
middleware/tools sites: it reads runtime.context["user_id"] (the owner
carried in the run request's context, which survives background-task
boundaries) and falls back to get_effective_user_id() for no-auth / browser
paths. Caller-supplied metadata still wins via inject_langfuse_metadata's
setdefault.

feat(skills): bind request-scoped secrets for autonomously-invoked skills (A+) (#3938)
* feat(skills): bind request-scoped secrets for in-context (autonomously invoked) skills

Extends the #3861 binding point A (slash-activation only) to A+: the
injection set is recomputed on every model call from two unioned
sources — the run's most recent slash activation (persisted on the run
context so the tool loop keeps the binding) and skills the model
actually loaded in this thread (ThreadState.skill_context), re-validated
against the live registry each call.

Authorization stays three-gated regardless of activation style: skill
enabled by the operator, values supplied per-request by the caller in
context.secrets (never persisted server-side, never from the host env),
names declared in the skill's required-secrets frontmatter. Because the
set is replaced per call, eviction from skill_context or a caller that
stops supplying a value revokes injection on the next call.

New frontmatter field secrets-autonomous (default true) lets a skill
restrict binding to explicit slash activation; malformed values fail
closed to false. Binding changes are recorded as a
middleware:skill_secrets journal event carrying names only.

Design informed by a survey of peer systems (Claude Code, Codex CLI,
opencode, pi, deepagents, hermes-agent, QwenPaw) and specs
(agentskills.io, MCP 2025-11-25): the industry trust boundary is
enable-time consent plus caller-scoped credentials, not per-invocation
ceremony; no surveyed system scopes secrets to an activation turn.

Part of #3914

* refactor(skills): centralize secret context keys, document intentional per-call reload

Review follow-ups (no behavior change): move the two private binding keys
(__slash_skill_secret_source, __skill_secrets_binding_audit) into
secret_context.py and add them to REDACTED_CONTEXT_KEYS so the redaction
allowlist stays a complete guard even though both keys hold names only.
Document why _in_context_secret_sources reloads skills every call rather
than caching: load_skills re-reads enabled state so an operator disabling
a skill revokes its binding on the next model call — an mtime cache would
miss enable/disable toggles and keep injecting after a disable.

* fix(skills): match in-context secret bindings by path only, never by name

Review finding (confused deputy): _in_context_secret_sources fell back to
name matching when a skill_context path did not resolve. DeerFlow lets a
custom skill shadow a same-named public/legacy one (load_skills de-dupes
by name, custom wins), so a thread that read public/foo could bind the
custom foo's declared secrets although the custom skill was never loaded
in the thread. The recent user-isolation path changes make by-path misses
(and thus the dangerous fallback) more likely. Drop the by-name fallback:
match strictly by the exact container file path the model read; an
unresolved path simply does not bind (the safe direction). Regression
tests cover the shadowing case and a stale path.

Part of #3914

* fix(skills): resolve secret-binding sources via registry; strip caller __-keys

Security review (willem-bd, #3938):

1. Forged `__slash_skill_secret_source` bypassed the enabled/allowlist/
   secrets-autonomous gates. runtime.context is caller-mergeable, and the
   slash source was trusted as authoritative (its stored requirements were
   injected directly). Now the slash source records only the activated
   skill's canonical container path, and BOTH the slash and in-context
   sources resolve the live registry skill by normalized path each call
   (_resolve_registry_skill) — binding only that real, enabled, allowlisted
   skill's own declared secrets. A forged path resolves to nothing. As
   defense in depth, build_run_config strips caller-supplied __-prefixed
   context keys at the gateway boundary.
2. Malformed caller requirements crashed the run (unguarded tuple unpack /
   DoS). The middleware no longer unpacks caller-provided requirement data
   at all — declarations come from the registry — so a malformed source
   fails closed instead of raising.
3. Path-normalization asymmetry silently disabled in-context binding on a
   trailing-slash container_path config. Both the registry keys and the
   lookup path are now posixpath.normpath'd.

Regression tests: forged source rejected, forged-but-real path ignores
caller requirements + allowlist, malformed source fails closed, trailing-
slash config binds, gateway strips __-keys.

Part of #3914

* docs(skills): correct _SLASH_SECRET_SOURCE_KEY comment and note fail-closed trade-off

Post-review cleanup: the key now stores only the canonical container path
(the comment still described the pre-fix skill-name+requirements shape),
and document that a transient registry-load failure fails closed (drops
the binding for that call) rather than trusting stale data.

feat(gateway): cache-aware cost accounting (#3920)
* feat(gateway): cache-aware cost accounting + /api/console observability endpoints

- Capture prompt-cache hits (usage_metadata.input_token_details.cache_read)
  in RunJournal and SubagentTokenCollector as a sparse cache_read_tokens key
  in token_usage_by_model (JSON field — no schema migration; legacy bucket
  shapes unchanged)
- New read-only /api/console router: GET /stats (headline counters),
  GET /runs (cross-thread paginated history joined with thread titles),
  GET /usage (zero-filled daily token series + per-model breakdown);
  user-scoped, 503 on the memory database backend
- Optional models[*].pricing (currency, input_per_million,
  output_per_million, input_cache_hit_per_million) powers real spend
  estimation; cache-hit input tokens are billed at the hit price (omitted
  hit price falls back to the miss price as a conservative upper bound);
  unpriced models yield cost: null
- create_chat_model strips the presentation-only pricing block so it never
  reaches the provider client (unknown kwargs are forwarded into the
  completion payload and break live calls)
- Tests: console router SQLite round-trips, journal/collector cache capture
  incl. a DeepSeek raw-usage pin test, factory strip regression

* refactor: address review feedback on cost sum and sparse cache_read_tokens

- console.py: replace the walrus-in-generator total-cost sum with an
  explicit loop (review noted the multi-line form reads ambiguously)
- token_collector.py: omit cache_read_tokens from usage records when the
  provider reported no cache hits, matching the journal's sparse
  per-model bucket shape; absent is treated as 0 downstream
- add a regression test pinning the sparse record shape

Replace the full-metadata <available_skills> system-prompt block with a
compact <skill_index> (names only) and an on-demand describe_skill tool
when skills.deferred_discovery: true (default: false / backward compat).

New modules:
- skills/catalog.py — SkillCatalog (immutable, searchable; select: has no

- skills/describe.py — build_describe_skill_tool(catalog) closure;
  build_skill_search_setup() wires SkillSearchSetup into both the
  LangGraph agent factory (agent.py) and DeerFlowClient (client.py)

Changes:
- Skill @dataclass(frozen=True); allowed_tools/required_secrets list→tuple
- Skill First prompt line gated on skill_names (deferred vs legacy wording)
- get_skills_prompt_section: short-circuit storage on deferred path;
  merge user_id (upstream) + skill_names (this PR) params
- describe_skill tool parameter named "name" (matches prompt wording)
- select: branch removes [:MAX_RESULTS] cap (exact request, not ranking)

feat(channels): add GitHub as a webhook-driven channel (#3754)
* feat(channels): add GitHub event-driven agents (#3754)

Add a webhook-driven GitHub channel with fail-closed webhook routing, deterministic per-agent PR/issue threads, mention-gated trigger fan-out, GitHub App token injection for sandboxed gh/git commands, and backend/AGENTS.md documentation.

* fix(llm-middleware): classify bare IndexError as transient

Upstream chat providers occasionally return 200 OK with an empty
generations list (observed against Volces "coding" on
ark.cn-beijing.volces.com). When that happens,
langchain_core.language_models.chat_models.ainvoke raises
``IndexError: list index out of range`` at
``llm_result.generations[0][0].message`` and kills the run.

Treat a bare IndexError reaching the middleware as a transient
upstream-payload glitch and route it through the existing
retry/backoff path instead of failing the whole agent run. The
retry budget and backoff schedule are unchanged.

Adds three regression tests covering the classifier and both the
recover-on-retry and exhausted-retries paths.

* fix(runtime): ignore stale LLM fallback markers from prior runs

When a run on a thread ends with the LLM-error-handling middleware emitting
a `deerflow_error_fallback`-marked AIMessage (e.g. after the IndexError
empty-generations classification fix lands), that message is persisted to
the thread's checkpoint as part of the messages channel. LangGraph replays
the full message history in `stream_mode="values"` chunks, so every
subsequent run on the same thread re-streams the stale fallback marker —
and the worker's chunk scanner faithfully picks it up, flipping
`RunStatus.success` to `RunStatus.error` for runs that themselves had
no LLM failure at all.

Snapshot the set of pre-existing message ids from the pre-run checkpoint
and thread it through `_extract_llm_error_fallback_message` /
`_try_extract_from_message` as a filter. Markers on history messages are
ignored; markers on fresh messages produced during this run still trip
the error path. Falls back to an empty set when the checkpointer is
absent or the snapshot can't be captured, preserving the prior behavior
on first-run / no-state paths.

Adds unit tests for the new filter (helper-level and `_collect_pre_existing_message_ids`)
plus an integration test exercising the full `run_agent` path with a stale
history checkpointer.

* fix(channels): make github channel fire-and-forget to avoid httpx.ReadTimeout on long runs

GitHub agent runs (clone -> edit -> test -> push -> PR) routinely exceed
the langgraph_sdk default 300s read deadline. The manager's runs.wait
call kept an HTTP stream open for the entire run lifetime, so the long
run blew up with httpx.ReadTimeout and the outer except branch then
released the dedupe key and emitted a false 'internal error' outbound.

The GitHub channel's outbound send is log-only by design: agents post to
the issue/PR via the gh CLI in the sandbox when they choose to comment
or create a PR. There is nothing for the manager to ferry back, so the
long-poll was pure overhead.

This change adds ChannelRunPolicy.fire_and_forget (default False) and
sets it True for the github channel. When fire_and_forget is True,
_handle_chat dispatches via client.runs.create (short POST, returns
once the run is pending) instead of client.runs.wait, and skips the
response-extraction + outbound-publish block. ConflictError on a busy
thread still trips the standard THREAD_BUSY_MESSAGE path so behavior on
the busy case is preserved for any future non-github fire-and-forget
channel.

Other (non-github) channels are unchanged: their policy defaults
fire_and_forget=False and they continue to dispatch via runs.wait.

Adds 6 regression tests in tests/test_channels.py::TestGithubFireAndForget:
- Default ChannelRunPolicy.fire_and_forget is False.
- The github policy registers fire_and_forget=True.
- github inbound calls runs.create, not runs.wait, with the right kwargs.
- github inbound publishes no outbound on success.
- ConflictError from runs.create still emits THREAD_BUSY_MESSAGE.
- Non-github channels (slack) still dispatch via runs.wait.

* test(lead-agent): accept user_id kwarg in skill-policy test stubs

The two GitHub-channel tests added in #3754 stubbed
_load_enabled_skills_for_tool_policy with a lambda that only accepted
`available_skills` and `app_config`, but the real function (and its call
site in agent.py) also passes `user_id`. This raised TypeError on every
run, failing backend-unit-tests.

Add `user_id=None` to match the three sibling stubs in the same file.

* refactor(gateway): disambiguate context-key set names

The two frozensets _INTERNAL_ONLY_CONTEXT_KEYS and _CONTEXT_ONLY_KEYS
shared a confusable "CONTEXT_ONLY" token in different orders, and the
first broke the _CONTEXT_<X>_KEYS pattern of its sibling
_CONTEXT_CONFIGURABLE_KEYS. Rename to make the distinct axes explicit:

  _CONTEXT_INTERNAL_CALLER_KEYS  - WHO: internal callers (scheduler) only
  _CONTEXT_RUNTIME_ONLY_KEYS     - WHERE: runtime context only, never configurable

Pure rename, no behavior change.

feat: add scheduled tasks MVP (#3898)
* feat: add scheduled tasks MVP

* fix: harden scheduled task execution semantics

* feat(scheduled-tasks): preset-driven schedule form with timezone and live preview

Replace the raw cron input with a preset Select (hourly/daily/weekly/monthly/custom)
plus structured inputs (time picker, weekday toggles, day-of-month), datetime-local
for one-time tasks, a timezone selector defaulting to the browser timezone, and a
live human-readable preview. Reuses one ScheduledTaskScheduleInput for create and
edit; backend contract unchanged; zero new deps (pure Intl + DST-safe offset helpers).

* feat(scheduled-tasks): full-page i18n + recipe templates + E2E locale pin

Localize the rest of the scheduled-tasks page (filters, detail pane, actions,
edit form, run list, enum values) via t.scheduledTasks.* in en/zh. Add four
built-in recipe templates (GitHub Trending, news digest, issue triage, weekly
report) exposed as a chip row that pre-fills title + prompt + schedule. Pin
Playwright locale to en-US so E2E selectors stay stable against i18n. No backend
change, no new deps.

* fix(scheduled-tasks): idempotent 0003 migration, update head constants, future-date once test

Merge with main surfaced three CI failures:
- 0003_scheduled_tasks create_table collided with legacy test seeds that
  build from full metadata; guard with inspector.has_table so the revision
  no-ops when the table already exists (0004/0005 are already idempotent via
  _helpers.py).
- persistence bootstrap concurrency/regression tests pinned HEAD to main's
  0002_runs_token_usage; bump to the new head 0005_scheduled_task_thread_nullable.
- once-task router test used a fixed past run_at and tripped the
  must-be-in-the-future validation; use a future date.

* address review: ok-check, 502 for trigger failure, mock fields, migration filename, doc fences

- fetchThreadScheduledTasks now checks response.ok like the other fetchers.
- trigger endpoint returns 502 (not 409) when dispatch fails outright, so
  clients can distinguish a real conflict from a server-side failure.
- E2E mock normalizes scheduled-task objects with context_mode/last_thread_id
  and nullable thread_id, matching the backend contract the UI renders against.
- Rename 0002_scheduled_tasks.py -> 0003_scheduled_tasks.py to match its
  revision id (file was renamed in spirit already; filename now follows).
- CONFIGURATION.md: close the Tool Groups yaml fence and drop the stray fence
  after the Scheduler notes so the sections render correctly.

* fix(scheduled-tasks): harden lease, poller, config, and frontend UX after review

* fix(scheduled-tasks): harden run lifecycle, overlap skip, non_interactive gating, and DST conversion after review

- defer a once task's terminal status to the run-completion hook; the task
  stays running until the real outcome, and a startup sweep cancels once
  tasks orphaned by a crash (launch-time 'completed' could stick forever)
- record interrupted runs as a distinct 'interrupted' run status with a
  readable message; an interrupted once task ends 'cancelled', not 'failed'
- enforce overlap_policy=skip for fresh_thread_per_run via an active-run
  pre-check (same-thread ConflictError can never fire across fresh threads)
- protect terminal run statuses from the late launch-path 'running' write
- honor context.non_interactive only for internally-authenticated callers;
  arbitrary clients can no longer strip ask_clarification
- fix DST-stale timezone offset in zonedLocalToUtcIso by re-deriving the
  offset at the resolved instant (once tasks fired an hour late around
  spring-forward and the create->edit round-trip diverged)
- drop dead ScheduledTaskRunRepository.update_by_run_id; share one Gateway
  API error helper between channels and scheduled-tasks frontends

* fix(scheduled-tasks): close review round-3 gaps in guards, concurrency, and API ergonomics

- scrub internal-only context keys (non_interactive) from the assembled run
  config for non-internal callers: gating body.context alone left the same
  key smuggle-able through the free-form body.config copied verbatim by
  build_run_config
- guard update_after_launch with protect_terminal so the launch bookkeeping
  write cannot clobber a once task already finalized by a fast-failing run's
  completion hook (parent-row sibling of the run-row guard)
- reject a manual trigger while the task has an active run (409) instead of
  launching a duplicate concurrent run on fresh_thread_per_run
- re-arm a terminal once task to enabled when PATCH pushes run_at into the
  future; previously the endpoint returned 200 with a next_run_at that could
  never be claimed
- make max_concurrent_runs a real global cap: each poll claims only into the
  remaining budget of active (queued/running) scheduled runs
- paginate GET /scheduled-tasks/{id}/runs (limit<=200, offset) and push the
  thread filter of /threads/{id}/scheduled-tasks into SQL
- stamp context.user_id on scheduler-launched runs, matching IM channels, so
  user-scoped guardrail providers see the owning user

fix(gateway): offload gateway upload file IO (#3935)
* fix(gateway): offload gateway upload file IO

Move Gateway upload router filesystem work off the asyncio event loop by
using a dedicated ContextVar-preserving file IO executor. Use async sandbox
acquisition for non-mounted sandbox uploads and offload remote sandbox sync
together with host file reads.

Add blocking-IO regression coverage for upload, list, delete, and remote
sandbox sync paths.

* fix(gateway): align file IO worker env var prefix

Rename the file IO executor worker-count environment variable from
DEERFLOW_FILE_IO_WORKERS to DEER_FLOW_FILE_IO_WORKERS to match the repo's
existing runtime configuration prefix convention.

feat(channels): expose IM channel_user_id to sandbox commands as DEERFLOW_CHANNEL_USER_ID (#3926)
* feat(channels): expose channel_user_id to sandbox commands as DEERFLOW_CHANNEL_USER_ID

IM-channel skills need the sender's platform identity (Feishu open_id,
Slack Uxxx, ...). The channel manager already writes channel_user_id into
body.context, but the Gateway whitelist dropped it. Forward it into the
runtime context only (never configurable, which is checkpointed), and have
bash_tool export it as a fixed env var through a shell-quoted command
prefix.

The identity deliberately does not ride execute_command(env=...): that
channel is reserved for request-scoped secrets, and a non-empty env
switches AioSandbox onto the bash.exec path (fresh session per call,
image >= 1.9.3 required), which would have broken every IM bash command
on older sandbox images and abandoned persistent-shell semantics on new
ones. A command-string export keeps the legacy path, stays visible in
audit logs (it is an identifier, not a secret), and gives per-call
correctness in group chats where one thread and sandbox are shared by
senders with different platform ids.

Skipped on the Windows local sandbox, whose PowerShell/cmd.exe fallback
has no POSIX export.

Part of #3914

* feat(channels): propagate channel_user_id to subagents; cap value length

Review findings from the pre-PR verification pass:

- Subagent delegation dropped the sender identity: task_tool now captures
  channel_user_id from the parent runtime context and the executor
  forwards it into the subagent's context, mirroring the guardrail
  attribution fields (user_role/oauth_*/run_id). Without this, bash
  commands delegated via task lost the group-chat sender's id.
- body.context is client-writable on web requests, so values over 256
  chars are ignored instead of bloating every command string sent to the
  sandbox.

* fix(channels): set-or-unset channel_user_id so identity is per-call regardless of AIO session persistence

Review (willem-bd): the identity export could leak across senders in a
shared group-chat AIO sandbox. The AIO no-env path reuses a persistent
shell session (the class-lock reason, #1433), and the 256-char/type guard
made some commands carry no prefix — so a dropped-id command could resolve
the id a previous sender exported.

Make per-call correctness independent of session semantics: an IM-channel
command (channel_user_id present in context) now always carries an explicit
prefix — export VAR=<quoted> for a valid id, or unset VAR for an unusable
one (empty / non-str / over the cap). Non-IM runs (no key) are untouched.
A prefix unset has none of the '& ; unset' suffix hazard raised earlier.

Verified on a real AIO 1.11.0 container: the no-id shell path auto-creates
a session per call (does not persist today), but an explicit shared session
DOES persist (export stale-A -> readback [stale-A]); the unset prefix
clears it (-> []). So the fix holds even on an image whose no-id path
persists. Regression tests cover the dropped-id group-chat window and the
non-IM passthrough.

Part of #3914

* test(channels): align channel_user_id task test with new Command return shape

The merge from main changed task_tool to return a Command(update=...)
instead of a plain string; update the assertion to extract the tool
message via the existing _task_tool_message helper, matching the sibling
tests. Fixes the CI backend-unit-tests failure introduced by the merge.

fix(subagents): inherit LoopDetectionMiddleware to break tool loops (#3875) (#3931)
Subagents build their runtime chain via build_subagent_runtime_middlewares,
which attached none of the lead's runaway guards — no LoopDetectionMiddleware.
A degenerate subagent tool loop therefore ran unchecked until max_turns,
re-sending a growing context each turn (the #3875 4.4M-token burn).

Append LoopDetectionMiddleware.from_config(app_config.loop_detection) to the
subagent chain, gated by the existing loop_detection.enabled config (default
on) — no new config field. Registered before SafetyFinishReasonMiddleware to
match the lead's after-model ordering (the safety middleware requires placement
after LoopDetection). Subagents disallow task, so only the tool-loop heuristic
can fire here — no recursive-delegation false positives to worry about.

Phase 1 of #3875 (smallest blast radius). Phase 2 adds a deterministic
turn/token budget with a lead-visible stop reason; Phase 3 defers summarization.

Tests: enabled/disabled wiring + before-SafetyFinish ordering, mirroring the
lead chain's coverage.
