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

* fix: resolve CI lint errors and stale test assertion from merge
- Split long prompt line to fit 240-char limit
- Add missing `Any` import in list_uploaded_files_tool
- Remove unused `re` import in file_conversion (outline code moved)
- Remove unused `os` import in middleware test
- Fix test assertion: <uploaded_files> → <current_uploads> after main merge

* fix: add current_uploads to input sanitization exempt tags
The lazy-loading PR renamed <uploaded_files> to <current_uploads>.
The anti-drift guard scans all framework XML blocks and requires each
to be either blocked or explicitly exempted. current_uploads wraps
trusted server-generated file metadata, not user input, so it belongs
in the exempt set.

* fix: review feedback — memory pipeline, stale tags, state clearing, nits
- Match both tags in memory stripping pipeline (uploaded_files|current_uploads)
- Remove stale uploaded_files from _BLOCKED_TAG_NAMES
- Clear uploaded_files on all before_agent early-return paths
- Fix ponytail: stray word in file_conversion re-export comment

* fix: block current_uploads, sanitize only original user content
Per review feedback: instead of exempting <current_uploads> (which
allows user forgery), move it to _BLOCKED_TAG_NAMES and change
InputSanitizationMiddleware._process_request to scan only the
original user content (ORIGINAL_USER_CONTENT_KEY) when available.
Server-injected trusted blocks are no longer checked against the
blocked-tag denylist.

fix: 4th-round review — denylist, sanitization, scandir, nits
- Add "uploaded_files" back to _BLOCKED_TAG_NAMES (old tag still processed by
deermem; user forgery must be escaped) (consistency)
- Fix inaccurate rfind-fallback comment: UploadsMiddleware keeps string as
string, fallback is unreachable for strings (doc fix)
- Distinguish "empty string key" (upload without text) from "non-string key"
(caller forgery) so empty-text uploads never escape the server block (edge)
- Merge dual os.scandir(uploads_dir) calls into one list re-use (minor)
- Add comment on .md sibling skip known limitation: user-uploaded .md files
whose stem collides with a converted doc are hidden (boundary, no code change)

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

* fix: 5th-round review — dead code, subagent gating, integration test, perf, consistency
- Delete unreachable ORIGINAL_USER_CONTENT_KEY guard in rfind fallback
branch (original_user_content guaranteed non-empty str at that point)
- Remove list_uploaded_files from BUILTIN_TOOLS; add include_upload_tool
param to get_available_tools(), default True; task_tool.py passes False
so subagents no longer receive a tool whose state exclusion is broken
- Add integration test exercising real create_agent graph (not mocked
runtime.state) to verify LangGraph propagates before_agent state writes
into ToolRuntime.state during same-turn tool calls
- Cache DirEntry.stat() st_size in candidates tuple to avoid second
per-file syscall in the rendering loop

* fix(channels): pass files metadata through _human_input_message() for IM uploads
_human_input_message() was not passing additional_kwargs.files to the
downstream message. UploadsMiddleware read no files, wrote
uploaded_files=[], and list_uploaded_files reported same-run IM
attachments as historical files (fancyboi999 repro).
Fix: add files parameter to _human_input_message(), call site passes
files=uploaded. Regression test locks the contract.

* fix(channels): remove legacy <uploaded_files> manual prepend to fix double-injection regression
Commit 8d86dbf6 added files= pass-through to UploadsMiddleware but
left the manual _format_uploaded_files_block() prepend in place.
Every IM attachment reached the model twice — once via the legacy
<uploaded_files> block and once via <current_uploads>.
This commit removes the manual prepend and the now-dead
_format_uploaded_files_block() function. UploadsMiddleware is the
sole upload-context producer for both IM and web paths.

* fix(middleware): neutralize user-derived values inside <current_uploads> block
Upload-derived filenames, paths, outline titles, and preview text are
interpolated verbatim inside the trusted <current_uploads> wrapper,
which InputSanitizationMiddleware exempts from sanitization. A crafted
filename or document heading containing blocked authority tags would
bypass the guardrail and enter model context as trusted framework data.
Fix: call neutralize_untrusted_tags() on all four user-derived values
inside _format_file_entry(), preserving the outer <current_uploads>
wrapper untouched.

* fix(middleware): neutralize extension labels in omitted-file summary
Files exceeding the 10-item context cap bypass _format_file_entry().
Their extensions, derived from user-controlled filenames via
_extension_label(), were interpolated verbatim into the trusted
<current_uploads> wrapper — another path for blocked authority tags
to escape the guardrail.
Fix: neutralize extension values inside _extension_label(), the
single extraction point for all extension labels.

Apply neutralize_untrusted_tags() to every model-visible user-derived value
returned by list_uploaded_files: filename, virtual path, extension, outline
titles, outline preview lines, and omitted-file extension summary.
This closes the last remaining injection bypass in the upload lazy-loading
path - the <current_uploads> block and its omitted summary were already
neutralized (previous commits), but the list_uploaded_files tool produced
a second exit for the same attacker-controlled metadata that
ToolResultSanitizationMiddleware did not cover.

* fix(tests): add missing include_upload_tool=False to task_tool mock assertions
PR #4174 added include_upload_tool parameter to get_available_tools().

but 5 existing tests' assert_called_once_with expectations were not
updated, causing CI failures.

fix(uploads): claim the converted markdown filename before writing it (#4288)
* fix(uploads): claim the converted markdown filename before writing it * doc(changelog): record the converted-markdown filename collision fix Covers both surfaces that report markdown_file: the gateway uploads route and DeerFlowClient.upload_files. * fix(uploads): release the claimed markdown name when conversion fails Claiming the companion .md name before conversion means a conversion that writes nothing leaves the name reserved for the rest of the request, so a later same-stem upload is renamed against a name nothing occupies. Uploading notes.docx (conversion fails) + notes.md stored the user's file as notes_1.md with no notes.md on disk, where main kept notes.md. Discard the claim when conversion returns None, at both call sites that pre-claim it. Covers both victims: a later same-stem .md upload, and the next convertible's companion. |

fix(runs): cancel degrades to lease takeover for multi-worker (#4064)
* fix(runs): cancel degrades to lease takeover for multi-worker Work item 4 of the multi-worker ownership epic (https://github.com/bytedance/deer-flow/issues/3948). Problem: POST /runs/{run_id}/cancel landing on a non-owning worker returns 409 — the cancel button silently fails under GATEWAY_WORKERS>1 with no sticky routing. cancel() required the current worker to hold the in-memory task/abort_event, which any non-owner pod cannot satisfy. Changes: - RunManager.cancel() returns CancelOutcome enum (cancelled / taken_over / lease_valid_elsewhere / not_active_locally / not_cancellable / unknown) instead of bool, so the router can map each outcome to the right HTTP response. - New store primitive claim_for_takeover(): a single atomic conditional UPDATE that marks a run as error only when status IN (pending, running) AND (lease IS NULL OR lease < now - grace). Closes the stale-read / concurrent-heartbeat race — if the owner renews between our read and write, the UPDATE matches 0 rows and we surface lease_valid_elsewhere. - HTTP cancel + stream-join endpoints route on CancelOutcome: cancelled -> 202 (or 204 with wait=true); taken_over -> 202 immediately (no SSE streaming — the run is terminal on another worker, streaming would hang); lease_valid_elsewhere -> 409 + Retry-After header computed from lease_expires_at + grace_seconds. - RunManager.grace_seconds exposed as a public property; the router no longer reaches into _run_ownership_config. - _is_lease_expired extracted to a module-level function, shared by RunManager.cancel() and MemoryRunStore.claim_for_takeover(). - GATEWAY_WORKERS=1 + heartbeat_enabled=false is zero-regression: the non-local path short-circuits to not_active_locally, preserving the original 409 behaviour the existing tests pin. Tests: 12 new (5 store primitive + 4 cancel-takeover unit + 3 HTTP including a regression guard verifying POST /stream?action=interrupt on a dead-owner run returns 202 instead of hanging on SSE). 244 directly-related tests pass; 36/36 blocking-IO gate pass. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): guard update_status and self-terminate on takeover Two defenses close a split-brain window where the original owner could overwrite a peer's takeover status: - update_status (SQL + memory store) now guards on status IN ('pending','running'). When takeover already set the row to 'error', the owner's final status write matches 0 rows and is dropped. - _persist_status: when update_status returns False, check whether the row exists before attempting recovery via put(). If the row exists (takeover by another worker), skip recovery instead of blindly upserting over the takeover. - Heartbeat _renew_leases: when update_lease returns False (row no longer pending/running or owner changed), cancel the local task so wasted CPU is bounded to the next heartbeat tick (~10s) instead of the full task lifetime. Also fix three reviewer feedback items: - Re-fetch the store row when cancel() returns lease_valid_elsewhere, so Retry-After uses the owner's freshly-renewed lease instead of a stale value from request start. - Fallback 'unknown' in takeover error message when owner_worker_id is NULL (pre-ownership data). - Remove dead else-10 branch from grace_seconds property (unreachable — all callers are downstream of the heartbeat_enabled guard). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test(runs): pin split-brain defences from update_status guard + heartbeat Three tests lock down the takeover authoritativeness so a late-running owner cannot overwrite a peer's claim: - update_status must reject writes when the store row is already terminal (taken over by another worker). - _persist_status must skip row-recovery via put() when the row exists but has been taken over. - Heartbeat _renew_leases must cancel the local task when update_lease returns False (row claimed by another worker). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): precise outcome + log when local cancel loses to peer takeover Two reviewer precision nits on the split-brain defence: - _persist_status: branch the skip-reason log on existing["status"]. error → WARNING "peer takeover" (anomalous); interrupted/success → INFO "local cancel/completion race" (expected when user hits stop as the run finishes). Stops noisy false-positive takeover warnings in operator logs. - cancel() local path: when _persist_status returns False, re-check the store. If a peer's claim_for_takeover flipped the row to error between our in-memory cancel and the guarded update_status, surface taken_over instead of cancelled so the client sees a status consistent with the store. Test: test_cancel_returns_taken_over_when_peer_claims_during_local_cancel pins the race outcome. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): widen update_status guard, de-duplicate lease helpers, add coverage Round 3 of reviewer feedback: - Widen update_status guard to status IN ('pending','running','interrupted'). The original guard blocked interrupted→error (the rollback finalize path), losing the "Rolled back by user" message. interrupted is now permitted while error/success stay locked — takeover protection unchanged. - claim_for_takeover False now re-reads the store row to distinguish causes: owner renewed lease → lease_valid_elsewhere; row went terminal → not_cancellable; another worker already took it over → taken_over. - Extract _raise_lease_valid_elsewhere() helper to de-duplicate the 409+Retry-After block shared across cancel_run and stream_existing_run. - Extract _lease_expired_or_null() in persistence/run/sql.py to de-duplicate the lease-expiry SQL WHERE clause shared by claim_for_takeover and list_inflight_with_expired_lease. - 11 new tests: 5 SQL-layer claim_for_takeover (expired/valid/NULL/ terminal/nonexistent), 3 _compute_retry_after unit (NULL/unparseable/ normal), 2 claim re-read precision (terminal/takeover), 1 stream endpoint 409+Retry-After. Not addressed (non-blocking, reviewer agreed): - The 2–3 store.gets in the takeover cold path: optimizing the API to accept a pre-fetched record would couple the router to the manager more tightly than justified by the perf gain. - The lease-expiry inline loop in MemoryRunStore.list_inflight_with_- expired_lease pre-computes cutoff once for all rows; switching to the shared _is_lease_expired helper would recompute datetime.now() per row with no real benefit. 260 related tests pass; 36/36 blocking-IO gate pass; ruff clean. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(runs): de-duplicate lease-expiry helper, restore defensive fallback Address final round of review feedback: - Extract is_lease_expired to deerflow.utils.time (no _ prefix, public utility). Manager and MemoryRunStore now import from the same place instead of the store reaching backward into the manager for a private function. - Restore defensive else-10 fallback in grace_seconds property (removed in an earlier round). The guard is unreachable for current callers but protects future ones from AttributeError. - Comment the transient in-memory interrupted vs store error state when a local cancel is superseded by a peer takeover. - Comment the max(1, ...) floor in _compute_retry_after — the floor is a lower bound, not a poll interval; clients should apply jitter.

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.

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. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> |

feat(runtime): implement goal continuations (#3858)
* implement goal continuations * fix(goal): address review findings for goal continuations - goal: key the no-progress breaker on a signature of the latest visible assistant evidence instead of the evaluator's volatile free-text, so it actually fires on stalled turns; thread the signature through every worker persist / no-progress call site - goal: align _stand_down_reason default caps with should_continue_goal (8 / 2) so the two gate functions agree on goals missing the fields - runtime: offload the synchronous checkpointer fallback via asyncio.to_thread (goal.py + worker.py) to keep blocking IO off the loop - frontend: i18n the GoalStatus "Goal" label (goalLabel in en/zh/types) - frontend: extract pure composer helpers into input-box-helpers.ts with unit tests (parseGoalCommand, readGoalResponseError, skill suggestions) - tests: cover the evidence-based no-progress and default-cap behavior - docs: align backend/AGENTS.md goal paragraph with actual behavior - e2e: prettier-format chat.spec.ts (fixes the lint-frontend CI failure) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * feat(frontend): hide goal continuation counter until the agent continues The goal status bar rendered a raw "0/8" before any auto-continuation, which read as a mysterious score. Now the counter is hidden until continuation_count > 0, then shows "Continuing N/M" with a tooltip explaining the auto-continuation cap. - Extract getGoalContinuationDisplay into a pure helper (hides at 0) + unit tests - Add goalContinuing / goalContinuationTooltip i18n keys (en/zh/types) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(goal): address review findings for goal continuations Frontend correctness - Fix the optimistic /goal result permanently shadowing server goal state: the streamed continuation counter never surfaced for a goal set in-session. Extract a shared useActiveGoal hook (used by both chat pages) that reconciles the optimistic copy with server state via a goalReconciliationKey, de-duping the copy-pasted goal block across the two pages. - Stop /goal status|clear failures from escaping handleSubmit as unhandled rejections (handleGoalCommand now returns success; the run only starts when a goal was actually saved). - Use a function replacer for the goal-status toast so an objective containing $&/$1 isn't treated as a replacement pattern. Backend cleanliness / correctness - De-duplicate four byte-identical helpers (_call_checkpointer_method, _message_type, _additional_kwargs, _is_visible_message) by importing them from runtime.goal instead of re-defining them in the run worker. - Remove the dead `checkpoint_tuple.tasks` durability guard (CheckpointTuple has no tasks field) and document that pending_writes is the durability signal. - Decompose the 176-line _prepare_goal_continuation_input: extract _reread_goal_and_checkpoint and a _persist closure so the thread-unchanged guard and stand-down persistence aren't open-coded three times. Document the last-writer-wins write-window limitation as a follow-up. - Add a shared parse_goal_command helper and use it from the TUI and IM-channel /goal handlers (one place for the status/clear/set semantics).

fix: don't flag outline as truncated at exactly MAX_OUTLINE_ENTRIES headings (#3856)
extract_outline appended the {truncated: True} sentinel as soon as len(outline) >= MAX_OUTLINE_ENTRIES, i.e. right after the 50th heading, before knowing whether a 51st exists. A document with exactly 50 headings was therefore reported as truncated, and uploads_middleware injected a misleading 'showing first 50 headings' hint into the agent's context. Use a lookahead: only mark truncated once a heading beyond the limit is actually seen, then drop that extra entry. Adds an exact-boundary regression test.

refactor: share one message->text helper for journal + thread messages (#3747)
Part of #3742. RunJournal._message_text and the gateway thread-messages helper (thread_runs._message_text) reimplemented the same 'extract display text from a message' logic — str / list of string|{text}|nested{content} blocks joined without a separator / mapping with text|content key. They differed only in two ways: journal reads a BaseMessage attribute while thread_runs reads dict-shaped run_events rows, and journal falls back to message.text. Add deerflow.utils.messages.message_to_text(message, *, text_attribute_fallback=False) that handles both message shapes (attribute or mapping content access) and gates the .text fallback behind a flag, and have both call sites delegate. journal passes text_attribute_fallback=True; thread_runs uses the default. Behavior is unchanged at both sites. Verified behavior-preserving with an equivalence harness running both original implementations vs the shared helper over 98 inputs (BaseMessage and dict messages; str/list/mapping/None/numeric content; mixed blocks; .text attribute present/absent/non-str) -> 0 mismatches. Added tests/test_utils_messages.py; the journal last_ai_message extraction tests still pass. |

fix(gateway): return ISO 8601 timestamps from threads endpoints (#2599)
* fix(gateway): return ISO 8601 timestamps from threads endpoints (#2594) ThreadResponse documents created_at / updated_at as ISO timestamps, matching the LangGraph Platform schema (langgraph_sdk.schema.Thread exposes them as datetime, JSON-encoded as ISO 8601). The gateway threads router was instead emitting str(time.time()) — unix-second floats — breaking frontend new Date() parsing and producing a mixed ISO/unix wire format that also corrupted the search sort order. Centralize timestamp generation in deerflow.utils.time: - now_iso() — datetime.now(UTC).isoformat() - coerce_iso(x) — heals legacy unix-timestamp strings on read so the store converges to ISO without a one-shot migration threads.py: replace 6 time.time() call sites with now_iso(); wrap all read paths and Phase-2 checkpoint metadata with coerce_iso(); _store_upsert opportunistically heals legacy created_at on update; drop unused time import. thread_runs.py: reuse now_iso() instead of a private duplicate _now_iso(), preventing future drift between the two timestamp call sites. Tests: 9 unit tests for the helper; 5 integration tests pinning the ISO contract for create/get/patch/search and the legacy-healing path on the internal store upsert. Full suite: 2144 passed, 15 skipped, 0 failed. Closes #2594 * fix(gateway): coerce checkpoint metadata timestamps to ISO on read After the merge with main, three additional read paths in ``threads.py`` were still emitting raw ``str(metadata.get("created_at", ""))`` — ``get_thread_state``, ``update_thread_state``, and ``get_thread_history``. Same root cause as #2594: when the checkpoint metadata's ``created_at`` is a unix-second float (legacy data, or a checkpoint written by an older Gateway version), ``str(float)`` produces ``"1777252410.411327"`` and the frontend's ``new Date(...)`` returns ``Invalid Date``. The fix on the ``/threads/{id}`` GET path was already in place; these three sibling endpoints needed the same treatment. All four call sites now flow through ``coerce_iso``, so: - legacy float metadata heals to ISO on the way out, - ISO metadata passes through unchanged, - ``datetime`` instances (which the new ``coerce_iso`` branch handles explicitly) emit with the ``T`` separator instead of falling through to the space-separated ``str(datetime)`` form. Coverage added for the two endpoints not already pinned by the merge: - ``test_get_thread_state_returns_iso_for_legacy_checkpoint_metadata`` - ``test_get_thread_history_returns_iso_for_legacy_checkpoint_metadata`` Both pre-seed a checkpoint whose metadata carries the literal float from the issue body and assert the wire format is ISO. |

fix(uploads): handle split-bold headings and ** ** artefacts in extract_outline (#1838)
* feat(uploads): guide agent to use grep/glob/read_file for uploaded documents Add workflow guidance to the <uploaded_files> context block so the agent knows to use grep and glob (added in #1784) alongside read_file when working with uploaded documents, rather than falling back to web search. This is the final piece of the three-PR PDF agentic search pipeline: - PR1 (#1727): pymupdf4llm converter produces structured Markdown with headings - PR2 (#1738): document outline injected into agent context with line numbers - PR3 (this): agent guided to use outline + grep + read_file workflow * feat(uploads): add file-first priority and fallback guidance to uploaded_files context * fix(uploads): handle split-bold headings and ** ** artefacts in extract_outline - Add _clean_bold_title() to merge adjacent bold spans (** **) produced by pymupdf4llm when bold text crosses span boundaries - Add _SPLIT_BOLD_HEADING_RE (Style 3) to recognise **<num>** **<title>** headings common in academic papers; excludes pure-number table headers and rows with more than 4 bold blocks - When outline is empty, read first 5 non-empty lines of the .md as a content preview and surface a grep hint in the agent context - Update _format_file_entry to render the preview + grep hint instead of silently omitting the outline section - Add 3 new extract_outline tests and 2 new middleware tests (65 total) * fix(uploads): address Copilot review comments on extract_outline regex - Replace ASCII [A-Za-z] guard with negative lookahead to support non-ASCII titles (e.g. **1** **概述**); pure-numeric/punctuation blocks still excluded - Replace .+ with [^*]+ and cap repetition at {0,2} (four blocks total) to keep _SPLIT_BOLD_HEADING_RE linear and avoid ReDoS on malformed input - Remove now-redundant len(blocks) <= 4 code-level check (enforced by regex) - Log debug message with exc_info when preview extraction fails |

feat(uploads): add pymupdf4llm PDF converter with auto-fallback and async offload (#1727)
* feat(uploads): add pymupdf4llm PDF converter with auto-fallback and async offload - Introduce pymupdf4llm as an optional PDF converter with better heading detection and table preservation than MarkItDown - Auto mode: prefer pymupdf4llm when installed; fall back to MarkItDown when output is suspiciously sparse (image-based / scanned PDFs) - Sparsity check uses chars-per-page (< 50 chars/page) rather than an absolute threshold, correctly handling both short and long documents - Large files (> 1 MB) are offloaded to asyncio.to_thread() to avoid blocking the event loop (related: #1569) - Add UploadsConfig with pdf_converter field (auto/pymupdf4llm/markitdown) - Add pymupdf4llm as optional dependency: pip install deerflow-harness[pymupdf] - Add 14 unit tests covering sparsity heuristic, routing logic, and async path * fix(uploads): address Copilot review comments on PDF converter - Fix docstring: MIN_CHARS_PYMUPDF -> _MIN_CHARS_PER_PAGE (typo) - Fix file handle leak: wrap pymupdf.open in try/finally to ensure doc.close() - Fix silent fallback gap: _convert_pdf_with_pymupdf4llm now catches all conversion exceptions (not just ImportError), so encrypted/corrupt PDFs fall back to MarkItDown instead of propagating - Tighten type: pdf_converter field changed from str to Literal[auto|pymupdf4llm|markitdown] - Normalize config value: _get_pdf_converter() strips and lowercases the raw config string, warns and falls back to 'auto' on unknown values |

feat(uploads): inject document outline into agent context for converted files (#1738)
* feat(uploads): inject document outline into agent context for converted files
Extract headings from converted .md files and inject them into the
<uploaded_files> context block so the agent can navigate large documents
by line number before reading.
- Add `extract_outline()` to `file_conversion.py`: recognises standard
Markdown headings (#/##/###) and SEC-style bold structural headings
(**ITEM N. BUSINESS**, **PART II**); caps at 50 entries; excludes
cover-page boilerplate (WASHINGTON DC, CURRENT REPORT, SIGNATURES)
- Add `_extract_outline_for_file()` helper in `uploads_middleware.py`:
looks for a sibling `.md` file produced by the conversion pipeline
- Update `UploadsMiddleware._create_files_message()` to render the outline
under each file entry with `L{line}: {title}` format and a `read_file`
prompt for range-based reading
- Tests: 10 new tests for `extract_outline()`, 4 new tests for outline
injection in `UploadsMiddleware`; existing test updated for new `outline`
field in `uploaded_files` state
Partially addresses #1647 (agent ignores uploaded files).
* fix(uploads): stream outline file reads and strip inline bold from heading titles
- Switch extract_outline() from read_text().splitlines() to open()+line iteration
so large converted documents are not loaded into memory on every agent turn;
exits as soon as MAX_OUTLINE_ENTRIES is reached (Copilot suggestion)
- Strip **...** wrapper from standard Markdown heading titles before appending
to outline so agent context stays clean (e.g. "## **Overview**" → "Overview")
(Copilot suggestion)
- Remove unused pathlib.Path import and fix import sort order in test_file_conversion.py
to satisfy ruff CI lint
* fix(uploads): show truncation hint when outline exceeds MAX_OUTLINE_ENTRIES
When extract_outline() hits the cap it now appends a sentinel entry
{"truncated": True} instead of silently dropping the rest of the headings.
UploadsMiddleware reads the sentinel and renders a hint line:
... (showing first 50 headings; use `read_file` to explore further)
Without this the agent had no way to know the outline was incomplete and
would treat the first 50 headings as the full document structure.
* fix(uploads): fall back to configurable.thread_id when runtime.context lacks thread_id
runtime.context does not always carry thread_id (depends on LangGraph
invocation path). ThreadDataMiddleware already falls back to
get_config().configurable.thread_id — apply the same pattern so
UploadsMiddleware can resolve the uploads directory and attach outlines
in all invocation paths.
* style: apply ruff format

refactor: split backend into harness (deerflow.*) and app (app.*) (#1131)
* refactor: extract shared utils to break harness→app cross-layer imports Move _validate_skill_frontmatter to src/skills/validation.py and CONVERTIBLE_EXTENSIONS + convert_file_to_markdown to src/utils/file_conversion.py. This eliminates the two reverse dependencies from client.py (harness layer) into gateway/routers/ (app layer), preparing for the harness/app package split. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * refactor: split backend/src into harness (deerflow.*) and app (app.*) Physically split the monolithic backend/src/ package into two layers: - **Harness** (`packages/harness/deerflow/`): publishable agent framework package with import prefix `deerflow.*`. Contains agents, sandbox, tools, models, MCP, skills, config, and all core infrastructure. - **App** (`app/`): unpublished application code with import prefix `app.*`. Contains gateway (FastAPI REST API) and channels (IM integrations). Key changes: - Move 13 harness modules to packages/harness/deerflow/ via git mv - Move gateway + channels to app/ via git mv - Rename all imports: src.* → deerflow.* (harness) / app.* (app layer) - Set up uv workspace with deerflow-harness as workspace member - Update langgraph.json, config.example.yaml, all scripts, Docker files - Add build-system (hatchling) to harness pyproject.toml - Add PYTHONPATH=. to gateway startup commands for app.* resolution - Update ruff.toml with known-first-party for import sorting - Update all documentation to reflect new directory structure Boundary rule enforced: harness code never imports from app. All 429 tests pass. Lint clean. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: add harness→app boundary check test and update docs Add test_harness_boundary.py that scans all Python files in packages/harness/deerflow/ and fails if any `from app.*` or `import app.*` statement is found. This enforces the architectural rule that the harness layer never depends on the app layer. Update CLAUDE.md to document the harness/app split architecture, import conventions, and the boundary enforcement test. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add config versioning with auto-upgrade on startup When config.example.yaml schema changes, developers' local config.yaml files can silently become outdated. This adds a config_version field and auto-upgrade mechanism so breaking changes (like src.* → deerflow.* renames) are applied automatically before services start. - Add config_version: 1 to config.example.yaml - Add startup version check warning in AppConfig.from_file() - Add scripts/config-upgrade.sh with migration registry for value replacements - Add `make config-upgrade` target - Auto-run config-upgrade in serve.sh and start-daemon.sh before starting services - Add config error hints in service failure messages Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix comments * fix: update src.* import in test_sandbox_tools_security to deerflow.* Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: handle empty config and search parent dirs for config.example.yaml Address Copilot review comments on PR #1131: - Guard against yaml.safe_load() returning None for empty config files - Search parent directories for config.example.yaml instead of only looking next to config.yaml, fixing detection in common setups Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: correct skills root path depth and config_version type coercion - loader.py: fix get_skills_root_path() to use 5 parent levels (was 3) after harness split, file lives at packages/harness/deerflow/skills/ so parent×3 resolved to backend/packages/harness/ instead of backend/ - app_config.py: coerce config_version to int() before comparison in _check_config_version() to prevent TypeError when YAML stores value as string (e.g. config_version: "1") - tests: add regression tests for both fixes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: update test imports from src.* to deerflow.*/app.* after harness refactor Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |
