perf(boxlite): add benchmark-driven warm-pool reclaim tuning (#4001)
* bench: add provider-agnostic sandbox benchmark with BoxLite warm pool results

- scripts/bench_sandbox_provider.py: CLI for measuring acquire/run/release
  across providers, scenarios, workloads, and concurrency levels
- 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:
  cold acquire:  ~860ms
  warm reclaim:   ~14ms  (60x speedup)
  release:         ~0ms
  warm_hit_rate:  95%   (warm_same_thread)

* 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

* Update config_version to 21 in values.yaml

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: 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.

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.

fix(sandbox): stop setup-sandbox from pre-pulling the stale :latest sandbox image (#3983)
* fix(sandbox): stop setup-sandbox from pre-pulling the stale :latest image

scripts/setup-sandbox.sh's fallback (used whenever config.yaml has no
uncommented sandbox.image) pulled the volces mirror's :latest tag. We
confirmed in #3921/#3922 that this tag is frozen on the pre-1.9.3
all-in-one-sandbox digest (1.0.0.156), which lacks the /v1/bash/*
routes required-secrets skills need — so the one script whose entire
job is 'pre-pull a working sandbox image' was pre-pulling a known-broken
one. Pin the fallback to :1.11.0 instead.

Also update config.example.yaml's commented image: example and
'Recommended' line to the same version, so uncommenting the example
doesn't reproduce the same trap.

Out of scope on purpose: aio_sandbox_provider.py's DEFAULT_IMAGE
constant (the harness-level default for AioSandboxProvider itself)
is a separate, broader default-image decision already flagged to
maintainers in #3921 — this PR only fixes the pre-pull helper script.

Reported in #3914 (a real user deleted their stale local image, reran
make setup-sandbox, and got the same broken :latest image back).

* fix(sandbox): make setup-sandbox warn when the pull won't affect the runtime image

Self-review caught a real gap in the previous commit: AioSandboxProvider
resolves its image as `sandbox_config.image or DEFAULT_IMAGE`
(aio_sandbox_provider.py:214), and DEFAULT_IMAGE is deliberately left
untouched (still the frozen :latest, per #3921 — that's a maintainer
decision, not this PR's scope). So when config.yaml has no uncommented
sandbox.image, pre-pulling :1.11.0 alone creates a NEW inconsistency:
the script reports success pulling a modern image, but the sandbox
that actually starts still falls back to the broken :latest — silently
leaving the user's underlying required-secrets/bash.exec problem
unfixed, which is worse than the previous consistent-but-broken
behavior (pre-pull :latest, run :latest).

Make the unconfigured path loud about this instead of silent: print
the exact config.yaml snippet needed to make the pulled image actually
take effect.

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)

* 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

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

* 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)

* chore(config): remove unused backward-compat fields from ToolProgressConfig

Remove max_calls_per_intent and window_size fields that were marked
"Retained for backward compatibility; not used by the current state machine"
when the state machine was introduced.  Pydantic v2 ignores unknown fields
by default, so existing config.yaml files with these keys remain valid.

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

* fix(tool_progress): address PR review and multi-agent review findings

fix:
- Remove <80-char length gate for partial_success; only _PARTIAL_MARKERS now
- Add word-boundary regex for numeric HTTP codes (401/403/404/500) to avoid
  false positives like "500ms" or "4010 rows" triggering hard-block
- Add "task" to default exempt_tools (delegation primitive, not a search tool)
- Remove move_to_end() from _get_block_reason read path; blocked threads were
  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.

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

* 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

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.

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

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

* 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

feat(skills): deferred skill discovery via describe_skill tool (#3775)
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
  cap, keyword/prefix search caps at MAX_RESULTS=5)
- 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)
- AGENTS.md: document deferred_discovery config field + new modules

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

feat(gateway): add redis stream bridge (#3191)
* feat: add redis stream bridge

* Potential fix for pull request finding

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

* fix(gateway): address redis stream bridge review

Redis was imported eagerly through deerflow.runtime and declared as a hard dependency, which made memory-only installs load redis.asyncio at startup and left the lazy factory import ineffective. Move redis behind an optional extra, remove the public eager re-export, and keep make_stream_bridge as the only runtime import path with an actionable install hint when the extra is missing.

Because Docker deployments now default the stream bridge to Redis via DEER_FLOW_STREAM_BRIDGE_REDIS_URL, install the redis extra explicitly in Docker/dev container flows and teach the local uv-extra detector to infer redis from both stream_bridge.type and the Redis URL env var. This keeps Docker working while preserving slim non-Docker installs.

Harden the Redis bridge by batching XREAD replay, replacing brittle ResponseError string matching with a single fallback to 0-0 for malformed Last-Event-ID values, documenting connection/retention/fail-hard behavior, and adding fake plus opt-in real Redis coverage for XADD/XREAD, replay, invalid IDs, and MAXLEN trimming.

* fix(config): bump config version for stream bridge

* fix redis stream bridge terminal handling

* fix: repair uv.lock, format redis.py, and align Dockerfile extras test

The uv.lock file was missing a closing bracket for the redis extras
section, redis.py had a formatting issue caught by ruff, and the
Dockerfile extras test did not account for the hardcoded --extra redis
flag.

* fix(middlewares): read-before-write gate — error-string sandboxes fail open; serialize gate+execution per path (#3912 review)

- AIO/E2B read_file reports failures (incl. missing files) as 'Error: ...'
  strings instead of raising; the gate treated that string as existing file
  content and blocked first-write creation. Error-string reads now count as
  uninspectable: gate fails open, no mark is stamped.
- LangGraph runs one AIMessage's tool calls concurrently, so two same-turn
  writes could both pass on one stale mark before either mutation landed
  (and a read mark could hash a version the model never saw). Gate check +
  tool execution (and read + mark stamping) now share a per-(thread, path)
  critical section, separate from the tool-internal file_operation_lock.

feat(observability): add trace-id correlation and enhanced logging (#3902)
* feat(observability): add trace-id correlation and enhanced logging

- add opt-in gateway request trace correlation via X-Trace-Id
- enhance logging with configurable trace_id-aware formatting
- propagate deerflow_trace_id into runtime context and Langfuse metadata
- keep enhanced logging disabled by default to preserve existing behavior

* fix: harden trace correlation wiring

- Make logging enhancement a restart-required startup snapshot and remove per-request config reads from TraceMiddleware
- Restrict trace ids to printable ASCII before writing them to response headers, logs, and Langfuse metadata
- Gate implicit DeerFlowClient trace-id creation behind logging.enhance.enabled while preserving explicit caller opt-in
- Bind embedded client trace context per stream step to avoid generator ContextVar leaks and cross-context reset errors
- Rebind memory update trace ids in Timer/executor worker paths so enhanced logs keep the captured correlation id
- Remove unrelated __run_journal context overwrite from the trace-correlation change set

* fix(gateway): avoid eager app construction on package import

* fix(gateway): avoid config load during app import

Keep Gateway app construction import-safe when config.yaml is absent by
disabling TraceMiddleware only for that construction-time fallback path.
Startup lifespan still performs strict config loading before serving.

fix(gateway): clamp client-supplied recursion_limit to prevent runaway runs (#3903)
build_run_config() copied every top-level request key (except
configurable/context) verbatim into the LangGraph RunnableConfig, including
recursion_limit. The server default of 100 was fully overridable by the caller
with no upper bound, so a request like {"config": {"recursion_limit": 100000000}}
could make a single run execute effectively unbounded LangGraph super-steps
(each >= 1 LLM call), enabling runaway API cost / DoS.

Validate the client value server-side and clamp it into a safe range:
- valid positive ints are capped at a configurable ceiling
  (AppConfig.max_recursion_limit, default 1000 to match the existing
  frontend/public-skill default so legitimate deep runs are unaffected)
- invalid/non-positive/bool/None values fall back to the 100 server default
- applied on both the configurable and the LangGraph >= 0.6.0 context paths
- WARNING logged on clamp for observability

Add unit tests (including a configurable-ceiling case), expose
max_recursion_limit in config.example.yaml (config_version 16), and document
the ceiling/fallback in backend/docs/API.md.

feat(community): add Crawl4AI web_fetch provider (#3821)
* feat(community): add Crawl4AI web_fetch provider

Crawl4AI is a self-hosted, no-API-key web fetcher: it runs headless
Chromium and returns server-cleaned "fit" markdown directly via its
POST /md endpoint, so no client-side readability extraction is needed.
It sits alongside the existing self-hosted Browserless provider.

- deerflow.community.crawl4ai: async Crawl4AiClient + web_fetch_tool
  (reads base_url/timeout_s/token/filter from config; "Error:" string
  convention; 4096-char cap), mirroring the browserless provider
- tests: 17 unit cases (success, HTTP error, success:false, empty,
  timeout, request error, token header, truncation, config reads)
- config.example.yaml: commented web_fetch example
- doctor: register as a no-key (free) web_fetch provider
- setup wizard: add to WEB_FETCH_PROVIDERS (no API key)
- docs: README, CONTRIBUTING, CONFIGURATION, AGENTS provider lists

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(community): address Crawl4AI provider review feedback

- timeout: robust _coerce_timeout (bool / non-numeric -> default) mirroring
  jina, so 'timeout: off' no longer becomes 0.0 and times out every request
- read web_fetch config once per invocation and pass values into the client,
  so a concurrent hot-reload can't split base_url from filter
- rename config key timeout_s -> timeout to match jina/infoquest (the
  default providers); update config.example.yaml + setup wizard
- validate + normalize the markdown filter against {fit,raw,bm25,llm};
  unknown values fall back to fit with a warning instead of an opaque HTTP 400
- client: a non-JSON 200 body (reverse proxy / auth wall) now reports the
  content-type + snippet instead of a generic JSONDecodeError
- tests: 22 cases (added non-JSON-200, _coerce_timeout, _coerce_filter,
  invalid-filter fallback, read-config-once)

* feat(community): add Browserless web_capture screenshot tool

Add a web_capture tool that renders a page via Browserless /screenshot and
presents it through the artifact system, alongside the existing Browserless
web_fetch provider.

Hardening:
- SSRF guard: reject URLs resolving to private/loopback/link-local (incl. the
  169.254.169.254 cloud-metadata endpoint)/reserved/multicast/unspecified
  addresses; opt out via allow_private_addresses for internal targets.
- Surface a warning when Browserless renders a target page that itself
  responded with a non-2xx/3xx status (X-Response-Code), so an error/anti-bot
  page is not mistaken for valid visual evidence.
- Dedupe colliding output filenames instead of silently overwriting prior
  captures.

Docs: comment out token: $BROWSERLESS_TOKEN in tool examples (an unset $VAR
fails AppConfig startup) and document allow_private_addresses.

* fix(community): format web_capture guard + document local Browserless startup

Address PR #3881 review: fix the lint-backend failure (ruff format on
browserless/tools.py) and add local Browserless startup instructions to
CONFIGURATION.md so reviewers can run the service to try web_fetch/web_capture.

fix(sandbox): stop blocking bash commands (e.g. servers) from hanging the turn (#3864)
* fix(sandbox): stop blocking bash commands from hanging the turn

Starting a server through the host bash tool (e.g. `python -m http.server`)
could hang the whole turn for the full 600s timeout. `LocalSandbox.execute_command`
used `subprocess.run(capture_output=True)`, whose captured pipes are inherited
by any process the command spawns — so a backgrounded long-lived process
(`server &`) keeps the read end open and blocks `communicate()` until the
timeout fires, even though the foreground command already returned. Commands
that read stdin blocked the same way, and on timeout only the direct child was
killed, leaving orphaned process groups.

Rework the POSIX path to capture stdout/stderr via temp files instead of pipes,
take stdin from /dev/null, and run the command in its own session/process group:

- Backgrounded long-lived processes (servers) now return immediately while the
  process keeps running.
- A command reading stdin gets immediate EOF instead of blocking.
- A genuinely blocking foreground command is bounded by a configurable
  wall-clock timeout; on timeout the whole process group is killed and the agent
  gets an explanatory notice telling it to background long-lived processes.

The timeout is configurable via `sandbox.bash_command_timeout` (default 600).
The Windows path is unchanged. Adds focused regression tests and updates docs.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(sandbox): instruct the agent to background long-lived processes

The code fix bounds a foreground server with a timeout, but the turn still
waits the full timeout before the run continues. Add the prompt-side half:
the bash tool description now tells the model to ALWAYS start long-lived
processes (e.g. web servers) in the background with output redirected, so the
tool returns immediately. The timeout notice points at the same readable
workspace log path. Pins the guidance with a test.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(sandbox): make fallback-kill exception explicit and observable

Address automated review: the inner `except OSError: pass` in
_terminate_process_group silently swallowed the case where the direct-child
fallback kill found the process already gone. Make the intent explicit with a
comment and a debug log instead of a bare pass.

feat(memory): add guaranteed injection for correction facts with graceful fallback (#3592)
* feat(memory): add guaranteed injection for correction facts with graceful fallback

When the token budget is tight, high-value facts (e.g. user corrections)
can be silently evicted by lower-priority regular facts. This change:

- Introduces configurable 'guaranteed_categories' (default: [correction])
  whose facts draw from a separate 'guaranteed_token_budget', ensuring
  they are never dropped due to budget pressure.
- Adds a graceful fallback to confidence-only ranking when the
  guaranteed-category path raises an unexpected exception.
- Refactors fact selection into a header-agnostic helper
  (_select_fact_lines) with explicit token accounting in the caller,
  eliminating double-counting of separators.
- Emits a single 'Facts:' header regardless of whether both guaranteed
  and regular facts are present.
- Extends the final safety truncation limit to account for the
  additional guaranteed budget so guaranteed facts survive end-to-end.

* refactor(memory): address review feedback on guaranteed injection

- Restore strict break-on-overflow in `_select_fact_lines` to preserve
  the caller's confidence-ordered ranking; add a regression test locking
  in the invariant that a shorter lower-confidence fact never slips
  ahead of a skipped higher-confidence one.
- Account for the inter-group `\n` separator between guaranteed and
  regular fact blocks in the regular budget (1-token precision fix).
- Clarify docstrings on `format_memory_for_injection` and
  `MemoryConfig.guaranteed_token_budget` to distinguish the common
  *displacement* case (total stays within `max_tokens`) from the rarer
  *additive* case (safety-truncation ceiling raised when guaranteed
  lines alone would overflow).

* fix(memory): address P1 safety truncation + P2s from review

- Structure-aware safety truncation: Facts block is now a protected
  suffix so guaranteed-category facts can never be silently discarded
  by a prefix-cut on overflow. Only the preceding (user/history)
  sections are eligible for truncation.
- Extend the same protected-suffix treatment to the except/fallback
  path by returning fact lines alongside the formatted section from
  _fallback_format_facts, avoiding string parsing.
- Single inter-section separator: facts section no longer embeds its
  own leading \n\n; the final "\n\n".join(sections) is the single

docs(config): add Atlas Cloud as an OpenAI-compatible model example (#3704)
Atlas Cloud (https://atlascloud.ai) exposes a single OpenAI-compatible
endpoint in front of many open models (DeepSeek, Qwen, Kimi, GLM,
MiniMax, Llama, ...). It needs no new provider code — it uses the same
ChatOpenAI + base_url pattern already documented for OpenRouter, Novita
and other gateways.

Add a commented example to config.example.yaml: a plain ChatOpenAI entry
plus a PatchedChatOpenAI variant for *-thinking model ids so
reasoning_content is replayed across multi-turn tool calls. The key is
read from the ATLASCLOUD_API_KEY environment variable via the $VAR form,
consistent with the other examples.

feat(community): add GroundRoute web search + fetch engine (#3675)
* feat(groundroute): add GroundRoute community web_search + web_fetch tools

GroundRoute is a meta search layer over six engines (Serper, Brave, Exa,
Tavily, Firecrawl, Perplexity) with price-based routing and failover. This
adds a self-contained community engine module (httpx only, no new required
deps) mirroring community/brave + community/tavily:
- web_search: POST /v1/search, normalize to {title,url,snippet,source_engine}.
- web_fetch: fetch a URL via mode=page.
- unit tests covering normalization, auth, clamping, and graceful errors.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(groundroute): register GroundRoute search + fetch in wizard and config

Add GroundRoute to the setup wizard provider lists (SEARCH_PROVIDERS +
WEB_FETCH_PROVIDERS) and as commented web_search + web_fetch examples in
config.example.yaml, mirroring tavily/serper/brave so SEARCH_API can select it.

* fix(groundroute): define empty groundroute extra for clean install

The docs install line 'uv add deerflow-harness[groundroute]' (mirroring the
tavily/exa/firecrawl pattern) referenced an undefined extra, which uv accepts
but warns about. GroundRoute needs no extra packages (httpx is a core dep), so
declare an empty 'groundroute' extra in deerflow-harness optional-dependencies
so the documented command resolves without a warning.

* fix(groundroute): per-tool api key + honor caller max_results (review)

Address maintainer review on PR #3675:
- _get_api_key(tool_name): web_fetch now reads the web_fetch config block's key
  instead of always web_search, so a flow that pairs GroundRoute fetch with a
  different search engine authenticates correctly. Mirrors serper/exa/firecrawl.
- web_search honors a caller-supplied max_results (sentinel default None),
  falling back to the configured value only when omitted, so the documented
  parameter is no longer silently discarded.
- warn-once is now keyed per tool. Tests cover both fixes (web_fetch key,
  agent max_results honored).

feat(community): add Serper Google Images provider for image_search (#3575)
* feat(community): add Serper Google Images provider for image_search

Add a Serper-backed `image_search` tool alongside the existing Serper
`web_search` provider, so users with a SERPER_API_KEY can pull Google
Images results as reference images for downstream image generation.

- Share request/response handling between web_search and image_search
  via `_serper_post` / `_response_items`, with bounded `max_results`
  (capped at 10) and query normalization.
- Add a best-effort SSRF guard (`_safe_public_url`) that rejects
  non-http(s), localhost and private/non-global IP image URLs; filtered
  entries are dropped and never consume the result limit.
- doctor: flag literal `api_key` values in config as a warning and steer
  users toward `.env` + `$SERPER_API_KEY`.
- Docs/config: document the Serper image_search provider and SERPER_API_KEY,
  and discourage committing literal keys to config.yaml.
- Tests: cover the provider end-to-end (100% line coverage on tools.py)
  and the doctor literal-key warning path.

* fix(community): block obfuscated IPv4 literals in Serper image SSRF guard

The image_search SSRF guard only rejected dotted-decimal IP literals; encoded
forms such as decimal (http://2130706433/), hex (0x7f000001) and octal
(0177.0.0.1) raised ValueError in ip_address() and were allowed through, even
though many HTTP clients resolve them to private addresses like 127.0.0.1.

Add _decode_ipv4() to permissively decode these inet_aton-style encodings and
apply the same is_global check; hostnames that do not decode to an IP (e.g.
cafe.com) are still treated as hosts and left to fetch-time re-validation.

Addresses PR review feedback. Tests cover decimal/hex/octal loopback and
private encodings plus non-IP edge cases; tools.py stays at 100% line coverage.

* test(community): cover IPv4-mapped IPv6 URL filtering

* fix(community): address Serper image search review feedback

- Block trailing-dot hostname SSRF bypass (localhost./127.0.0.1.) in
  _safe_public_url by stripping the FQDN root label before checks.
- Keep a filtered image/thumbnail URL empty instead of collapsing onto
  its counterpart, preserving the high-res/preview contract.
- Evaluate the SSRF guard once per field rather than twice.
- Treat a null-typed organic/images field as "no results" rather than a
  malformed payload.
- doctor.py: when a config $VAR is unset, fall through to the default env
  var before reporting it as not set.

* refactor _requires_bound_identity()

* refactor from_app_config()

* make format

* fix: reject unbound channel chats before semaphore

* security enhancement

* make format

* fix: enforce bound-identity admission at command entry point

The bound-identity gate only ran for non-command messages in
_handle_message() and as a fallback inside _handle_chat(). Commands had
no equivalent boundary, so an unbound platform user could send /new and
reach _create_thread() directly, creating an unowned Gateway thread and
empty checkpoint. Info commands (/status, /models, /memory) likewise
leaked Gateway state to unbound users.

Add the same _requires_bound_identity() check at the top of
_handle_command(), rejecting via _reject_unbound_channel_message() before
any thread creation or Gateway query. The gate is a no-op in legacy
open-bot mode (require_bound_identity=False) and auth-disabled mode.
Provider-level binding flows (/connect, /start) are consumed by the
provider adapter before reaching the manager, so they are unaffected.

Tests:
- unbound auth-enabled /new is rejected before threads.create
- bound auth-enabled /new still creates the thread

fix(subagents): raise general-purpose max_turns to 150 and default timeout to 30min (#3610)
* fix(subagents): raise general-purpose max_turns to 150 and default timeout to 30min

Deep-research subtasks failed out of the box with GraphRecursionError (Recursion limit of 100 reached): the built-in general-purpose subagent caps at max_turns=100. Raise it to 150 and bump the default subagent timeout from 900s (15min) to 1800s (30min) so the extra turns have time to run instead of shifting the failure to a timeout. The lead agent recursion_limit (100) is unchanged; the failures are subagent-only.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs(subagents): clarify lead recursion_limit is independent of subagent max_turns

Add comments at both lead recursion_limit=100 sites (gateway services + channel manager) explaining the lead's LangGraph super-step budget is separate from subagent depth, so the two 100s are not conflated. Comment-only, no behavior change.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* docs(subagents): clarify built-in vs custom timeout scope; pin bash max_turns in test

Review follow-ups: (1) clarify SubagentConfig docstring + global timeout field/comment that the 1800 default applies to built-in subagents (custom agents keep their own timeout_seconds); (2) pin bash.max_turns==60 in the defaults regression test so the config.example.yaml doc cannot drift; (3) rename test_default_timeout_preserved_when_no_config -> test_explicit_global_timeout_propagates_to_general_purpose since it intentionally exercises an explicit non-default 900. No runtime behavior change.

* Ensure runtime IM channels are ready after restart

* Persist disconnected IM channel state

* Address channel connection review comments

* Address channel connection review findings

Frontend connect flow:
- Open the runtime-config dialog only when a provider still needs
  credentials; configured providers go straight to the connect flow, so
  the binding-code/deep-link path is reachable from the UI again.
- After saving credentials, continue into the connect flow when a user
  binding is still required (multi-user mode) instead of stopping at a
  "Connected" toast.
- Extract shared provider-state helpers to core/channels/provider-state
  and add unit + e2e coverage for the direct-connect and
  configure-then-connect paths.

Provider status semantics:
- Report connection_status from the user's newest connection row;
  with no binding it is not_connected, except in auth-disabled local
  mode where a configured running channel is effectively connected.

Concurrency and event-loop correctness:
- Offload ChannelRuntimeConfigStore construction and writes, channel
  service construction, and Slack connection replies to threads; add a
  tests/blocking_io/ anchor for the runtime-config handlers.
- Consume binding codes with a conditional UPDATE so a code can only be
  used once under concurrent workers; retry upsert_connection as an
  update when a concurrent insert wins the unique constraint.
- Serialize ensure_channel_ready per channel so concurrent provider
  polls cannot double-start a channel worker.

Config and migration hardening:
- Stop mutating the get_app_config()-cached Telegram provider config;
  the runtime store now owns the UI-entered bot username.
- Register channel_connections in STARTUP_ONLY_FIELDS with the
  standardized startup-only Field description.
- Match the legacy unsafe-id bucket by recomputing its exact SHA-1 name
  so another user's same-prefix bucket can never be migrated.
- Remove the unused Telegram process_webhook_update path and document
  src/core/channels in the frontend docs.

* Address PR review comments on authz scoping and channel runtime

Security (review feedback from ShenAC-SAC):
- Scope internal-token callers to the connection owner carried in
  X-DeerFlow-Owner-User-Id instead of bypassing owner checks outright,
  in both require_permission(owner_check=True) and the stateless run
  endpoints. Internal callers keep access to their own and
  shared/legacy threads, and may claim a default-owned channel thread
  for its real owner, but a leaked internal token no longer grants
  cross-user thread access.
- Require admin privileges for POST/DELETE /api/channels/{provider}/
  runtime-config: runtime credentials and channel workers are
  instance-wide shared state (same model as the MCP config API).
  Read-only provider listing stays available to all users.

Performance (review feedback from willem-bd):
- Skip the redundant thread channel-metadata PATCH after the first
  successful backfill per thread.
- Reuse the per-connection Slack WebClient until its token changes
  instead of constructing one per outbound message.
- Reconcile channel readiness for all providers concurrently in
  GET /api/channels/providers.

Also resolve the code-quality unused-import flag in the blocking-io
anchor by pre-importing the channel service via importlib.

* Reconcile UI runtime channel config with config reload on restart

Main now reloads a channel's config.yaml entry on restart_channel()
(#3514, issue #3497). Adapt the user-owned connection flow to coexist:

- configure_channel() restarts with reload_config=False — the caller
  just supplied the authoritative config (browser-entered credentials
  that are never written to config.yaml), so a file reload must not
  clobber it with the stale on-disk entry.
- _load_channel_config() re-applies the UI runtime-store overlay used
  at startup, so an operator-triggered restart keeps browser-entered
  credentials for channels without a config.yaml entry and does not
  resurrect a channel disconnected from the UI.
- Offload the reload's disk IO (config.yaml + runtime store) with
  asyncio.to_thread, matching the blocking-IO policy on this branch.

feat(memory): add memory.token_counting config to avoid tiktoken network dependency (#3429) (#3465)
* feat(memory): add memory.token_counting config to avoid tiktoken network dependency (#3429)

Add a `memory.token_counting` option (`tiktoken` | `char`) so deployments in
network-restricted environments can opt out of tiktoken entirely. In `char`
mode the memory-injection budget uses a network-free character-based estimate
and never triggers the BPE download from openaipublic.blob.core.windows.net,
which could otherwise block for tens of minutes (see #3402).

Also harden the default `tiktoken` path:
- cache an in-flight LOADING sentinel so concurrent callers fall back
  immediately instead of spawning more blocking get_encoding threads when the
  first load is still running (e.g. under the 5s startup warm-up timeout);
- cache failures with a timestamp and retry after a cooldown so a transient
  network outage self-heals back to accurate counting without a restart;
- skip startup warm-up entirely in char mode.

The new config is surfaced via the memory config API and config.example.yaml
(config_version bumped). Default remains `tiktoken`, so existing deployments
are unaffected.

* fix(memory): use CJK-aware char token estimate and address review feedback

- Replace the flat len(text)//4 fallback with a CJK-aware estimate so
  Chinese/Japanese/Korean memory content does not over-fill the injection budget
- Document the internal tiktoken retry cooldown and char-mode escape hatch
- Sync CLAUDE.md / config.example.yaml / MEMORY_IMPROVEMENTS.md wording
- Fix MemoryConfigResponse mocks/assertions and add CJK estimate tests

fix(sandbox): make missing sandbox.mounts host_path a loud ERROR (#3244) (#3250)
In Docker production deployments, LocalSandboxProvider runs inside the
deer-flow-gateway container, so any `sandbox.mounts[].host_path` from
config.yaml is resolved against the gateway container's filesystem — not
the host machine. When the path isn't also bind-mounted into the gateway
service, the mount was silently dropped with only a WARNING log, leaving
agents reading an empty directory in production while the same config
worked under `make dev`.

Escalate the missing-host_path branch to logger.error with explicit
guidance about Docker bind mounts and docker-compose, so the failure is
hard to miss in default log configurations. Skip behaviour is preserved
to avoid breaking existing deployments.

Also clarify the misleading `VolumeMountConfig.host_path` field
description so it documents reality for both providers:

  - LocalSandboxProvider checks host_path from inside the gateway process
    (host in `make dev`, container in `make up`).
  - AioSandboxProvider (DooD) passes host_path straight to `docker -v`
    for the sandbox container, where the host Docker daemon resolves it
    from the host machine's perspective.

config.example.yaml's `sandbox.mounts` comment gets a Note: block
pointing operators at the docker-compose bind-mount requirement so the
Docker-mode gotcha is discoverable from the canonical template.

Adds a regression test that:
  - confirms missing host_path is still skipped (no behaviour break);
  - asserts an ERROR record is emitted referencing the offending paths;
  - asserts the message contains actionable Docker/gateway/docker-compose
    keywords so future refactors can't quietly downgrade it.

fix(web_fetch): support proxy for Jina reader in restricted networks (#3418) (#3430)
* fix(web_fetch): support proxy for Jina reader in restricted networks

The web_fetch tool built a bare httpx.AsyncClient() with no proxy
awareness, so users behind a corporate proxy / in Docker / WSL could
not reach https://r.jina.ai and web_fetch timed out.

- Add optional `proxy` / `trust_env` params to JinaClient.crawl and
  wire them from the `web_fetch` tool config (with type coercion for
  YAML string values).
- Pass internal service hostnames through NO_PROXY in both compose
  files so proxy env inherited via env_file does not break in-cluster
  calls (gateway/provisioner/etc).
- Load proxy vars from .env into the shell in scripts/docker.sh so the
  NO_PROXY interpolation can merge user-provided values on `make` path.
- Document proxy/trust_env options in config.example.yaml.

Closes #3418

The MiniMax provider now extracts the JSON `prompt` field (relying on prompt_optimizer to expand it) and fails fast with a clear error before calling the API when that field exceeds 1500 chars. Authoring stays provider-agnostic; Gemini still receives the full JSON.

* feat(podcast-generation): per-provider TTS concurrency and retry/backoff

Each TTS provider owns its concurrency internally — MiniMax runs single-threaded to reduce rate-limit failures, Volcengine keeps 4 workers — with automatic retry and backoff on transient HTTP and base_resp errors. No caller-facing concurrency knob.

* fix(skills): address Copilot review comments on generation skills

- video: add raise_for_status + timeout to the Gemini download/POST/poll calls so non-2xx responses surface as clear HTTP errors instead of JSON/KeyError or hangs
- video: check the task Fail status before the generic base_resp check so the failure keeps its task_id context
- video/image: create the output file parent directory before writing (matching music-generation) so nested output paths do not raise FileNotFoundError
- music: require a non-empty prompt and fail fast with ValueError instead of sending an empty prompt to the API

* fix(scripts): reclaim dev ports across worktrees in make stop/dev

All deer-flow worktrees (main checkout + linked worktrees) hardcode the same dev ports (8001/3000/2026), so a service started from any worktree must be reclaimable from another. stop_all now resolves the set of worktree roots (DEERFLOW_ROOTS) and treats a process as deer-flow-owned when its open files live under any of them. It also force-kills survivors on 2026 alongside 8001/3000, fixing `make dev` aborting on the nginx port preflight when a prior nginx lingered on 2026.

* fix(view-image): hide the injected image-context message from the UI

ViewImageMiddleware injects a HumanMessage (text + base64 images) so the vision model can see viewed images, but it was the only internal injector that set neither hide_from_ui nor a hidden name, so it leaked into the chat UI (and IM channels) as a user bubble reading "Here are the images you've viewed:". Mark it with additional_kwargs={"hide_from_ui": True}, matching todo/dynamic_context injections, which the frontend isHiddenFromUIMessage and the channel sender already honor. The model still receives the full content.

* fix(minimax): mark M2.7 models as text-only (no vision)

MiniMax M2.7 / M2.7-highspeed do not support vision; only M3 does. The
provider config asserted vision support for M2.7 in four places.

- config.example.yaml: 4 M2.7 entries -> supports_vision: false
- backend/docs/CONFIGURATION.md: M2.7 + highspeed -> supports_vision: false
- wizard: add LLMProvider.model_vision_overrides + extra_config_for() so
  selecting an M2.7 model writes supports_vision: false while M3 (default)
  keeps vision; wire it through setup_wizard.py
- tests: M2.7-highspeed fixture -> supports_vision=False; add
  test_minimax_vision_is_per_model

fix(suggestions): strip inline <think> reasoning before parsing follow-up questions (#3435)
Reasoning models such as MiniMax-M3 inline their chain-of-thought into the
message content as <think>...</think> (reasoning_split defaults to false)
instead of a separate reasoning_content field. The follow-up-suggestions
endpoint extracted the JSON array via find('[') / rfind(']'), which silently
broke whenever the reasoning text contained '[' or ']' — or when long thinking
hit max_tokens and truncated before the array was emitted — returning empty
suggestions.

- Add _strip_think_blocks() and apply it before JSON extraction; it removes
  complete <think>...</think> blocks (case-insensitive) and drops an unclosed
  <think> left by max_tokens truncation.
- Document the MiniMax thinking toggle in config.example.yaml
  (when_thinking_enabled: adaptive / when_thinking_disabled: disabled) so
  thinking_enabled=False actually disables reasoning on M3; note that M2.x
  models always think and rely on the defensive strip above.
- Tests cover complete/unclosed think blocks, brackets-inside-think, think +
  code-fence, and an end-to-end suggestions case reproducing the empty-result
  bug.

feat(agent): add ToolOutputBudgetMiddleware for oversized tool output protection (#3303)
* feat(agent): add ToolOutputBudgetMiddleware for oversized tool output protection

Closes #3289. Adds a unified middleware that enforces per-result budgets
on ALL tool outputs (MCP, sandbox, community, custom), preventing
oversized external tool results from blowing the model context window.

Design informed by claude-code (persistToolResult), hermes-agent
(tool_result_storage), and pi (OutputAccumulator) — the three most
mature implementations in production coding-agent frameworks.

Key features:
- Disk externalization: oversized outputs written to thread-local
  .tool-results/ directory, replaced with compact preview + file
  reference. Model can read full output via read_file with offset/limit.
- Fallback truncation: head+tail truncation when disk is unavailable
  (no thread_data, write failure), ensuring the context is always
  protected.
- read_file exemption: prevents persist-read-persist infinite loops
  (independently discovered by claude-code, hermes-agent, and pi).
- Per-tool threshold overrides via config.
- Line-boundary-aware truncation (no partial lines in previews).
- Multimodal content passthrough (images/structured blocks skip budget).
- Historical ToolMessage patching in wrap_model_call for checkpoint
  recovery scenarios.

Related: #3222 (design RFC), #1844 (comprehensive context management),
#3137 (write_file args compaction), #1677 (sandbox tool truncation).

* test: add MCP content_and_artifact format coverage

Add 5 tests for MCP tool output format (list of content blocks):
- text content blocks are extracted and budgeted
- multiple text blocks are joined and budgeted
- image content blocks are skipped (multimodal passthrough)
- mixed text+image blocks are skipped
- small text blocks pass through unchanged

Total test count: 59 (was 54).

* fix(agent): address Codex review findings for ToolOutputBudgetMiddleware

Three issues identified by Codex code review, all fixed:

1. `enabled` config field was unused — middleware now checks
   `config.enabled` and skips all processing when disabled.

2. `_build_fallback` could exceed `fallback_max_chars` — the marker
   text itself (~139 chars) was not deducted from the budget. Now
   pre-computes marker overhead and falls back to hard slice when
   max_chars is smaller than the marker.

3. Sync file I/O in async path — `awrap_tool_call` now delegates
   `_patch_result` to `asyncio.to_thread` to avoid blocking the
   event loop during disk writes.

Tests updated to use realistic fallback_max_chars values (500+)
that can accommodate the marker overhead, plus two new tests:
- `test_result_never_exceeds_max_chars` (parametric across sizes)
- `test_very_small_max_chars_does_not_crash`

* fix(agent): address Copilot review — path traversal, async perf, shared config

1. Path traversal defense: sanitize tool_name via _sanitize_tool_name()
   (strips separators, .., absolute paths), validate storage_subdir is
   relative, and verify resolved filepath stays inside storage_dir.

2. Async hot-path optimization: add _needs_budget() cheap check before
   asyncio.to_thread offload — small outputs (99% of calls) skip the
   thread overhead entirely.

3. Replace shared module-level _DEFAULT_CONFIG with _default_config()
   factory to prevent cross-instance mutation of mutable fields.

12 new tests: TestSanitizeToolName (5), TestExternalizePathTraversal (3),
TestNeedsBudget (4).

* fix(agent): correct preview hint to match read_file actual API

read_file uses start_line/end_line (1-indexed line numbers), not
offset/limit. The previous wording was copied from hermes-agent
which has a different read_file interface.

* perf(agent): hoist hot-path imports, add model-call pre-scan (review #3303)

Address maintainer review feedback:

1. Hoist inline imports to module level — `import asyncio` (was in
   awrap_tool_call hot path) and `from dataclasses import replace`
   (was in _patch_result) now live at module top.

2. Add a cheap pre-scan to _patch_model_messages so the historical
   message list is not rebuilt on every model call when nothing is
   oversized (the common case once results are budgeted at tool-call
   time). Also adds the same _needs_budget gate to the sync
   wrap_tool_call for symmetry with awrap_tool_call.

The pre-scan is refactored into per-tool-aware helpers
(_effective_trigger / _tool_message_over_budget) that mirror the exact
trigger conditions in _budget_content — including tool_overrides — so
the fast-path can never produce a false negative (silently skipping
budgeting for a tool with a low per-tool threshold).

7 new regression tests lock the per-tool-override-through-pre-scan path
and the model-call early return.
