* feat(extension-api): add task identity fields to CompactionEvent (0.2.10)
CompactionEvent carried the transform, its hashes and its counts, but
nothing that names the task, run or thread the compaction happened in.
An observer that wants to relate a compaction to the run that produced it
had to match hashes across sessions, which is unreliable.
Append three optional fields, task_id, run_id and thread_id (str | None,
default None). Existing keyword and positional construction is unchanged,
so already-released extensions keep working. The host fills them in the
next commit.
Bump deerflow-extension-api to 0.2.10 and the harness's exact pin with it.
* fix(extensions): hand compaction observers the live task store and its identity
The summarization middleware already recovers the live task store from
the runtime to observe its summary system call, and the registry
allocates that store precisely because a compaction observer is
registered. notify_context_compacted() then discarded it and handed every
observer a detached store, with a docstring claiming there was no live
task.
- The lead run worker and the subagent executor now seed every task store
they allocate with the task's TaskInfo, not only when a lifecycle
contributor is registered; the lifecycle notification reuses the seeded
object. A subagent without a parent run_id still gets no TaskInfo.
- compact_state() and acompact_state() pass the store from
task_store_from_runtime() to _record_compaction().
- notify_context_compacted() takes an optional task_store. A live store
goes to the observers and fills the event's task_id/run_id/thread_id
from its TaskInfo; without one (manual /compact runs outside any run)
observers still receive a detached store and the ids stay None.
For a background subagent the store keeps its public scope id (the
provider tool_call_id) while TaskInfo.task_id stays the execution id, as
lifecycle contributors already see it; the event follows TaskInfo.
* docs(extensions): document compaction event identity and seeded TaskInfo
The extensions guide and the developer manual still said compaction
observers always receive a detached store because no task is live at the
call site. Describe what the host does now: lead runs and subagents with a
parent run seed every task store with TaskInfo, compaction observers get
the live store, and CompactionEvent's task_id/run_id/thread_id come from
it; only manual /compact falls back to a detached store with None ids.
Adds the 0.2.10 row to the contract version table (PR number pending).
* docs(changelog): note compaction observers receive the live task identity
* docs(extensions): list compaction observers among task-store triggers
* docs: reference #7831 for the compaction event identity change
* docs(extensions): backfill contract history rows 0.2.5 to 0.2.9
The version table jumped from 0.2.4 to 0.2.10 although 0.2.5-0.2.9
shipped. Add those rows, attributing names merged without a bump to
the first release that carried them (#5796 in 0.2.5, #6920 and #5645
in 0.2.8, #7729 in 0.2.10). The page intro now says it documents
0.2.4 plus the 0.2.10 CompactionEvent fields, and points to the
history for the rest.
scan_skill_content and the goal evaluator built their chat model inline on
the Gateway event loop. When the provider reads local credential files (the
Codex provider reads the Codex CLI auth.json while it is constructed), each
scanned skill edit, rollback, install or agent-managed skill write, and the
evaluator construction in each goal run, did synchronous file IO on the
shared loop, so other requests and streams waited for it. #7484 removed the
same stall for the one-shot helpers and listed these two constructors in the
utils guidance as not covered.
Build both providers through run_assembly, as the one-shot helpers do: the
moderation model in scan_skill_content, the evaluator in
evaluate_goal_completion when no model is injected, and the run worker's
cached evaluator factory. A scan without app_config (the in-graph
skill_manage call) also reads the live config in that pool, and its
fail-closed fallback reuses that config instead of reading config.yaml again
on the loop; an unreadable config still fails closed. Verdicts, the
fail-open/fail-closed policy, error propagation and tracing are unchanged,
and cancellation during construction never starts inference.
tests/blocking_io/test_system_model_offloop.py builds a real CodexChatModel
under the strict Blockbuster gate. On main the scan fell back to its
fail-closed "unavailable" block, the evaluator raised BlockingError
(os.stat), and the worker stood the goal down as evaluator_failed.
* fix(runtime): charge a steered subagent's usage to the token budget
A task that finishes after a Steer reports through a receipt HumanMessage, so its usage never reached the dispatching AIMessage the token budget reads. Carry the usage over when the receipt is delivered.
* fix(runtime): report deferred usage with no AIMessage to charge
Log the rare case instead of dropping the usage silently, and scan for AIMessages once per delivery.
* fix(runtime): resume children paused for a withdrawn steer
wait_tool pauses every child as soon as a steer is pending, but only a
delivered steer sets steering_active, the flag finish_graph needs before it
resumes them. Removing the steer before delivery left the children parked
and the run waiting on them.
Release the children when deliver finds no input and no steer is in
progress. They stay paused during later model turns of a delivered steer.
* fix(runtime): release children paused by a steer withdrawn mid-turn
The steering_active guard skipped the release whenever another steer was
being handled. A child started during that turn is outside its
interrupted_children snapshot, so nothing resumed it after a second steer
was withdrawn and finish_graph waited forever.
Release every child a delivered steer does not hold. Each deliver re-takes
that snapshot, so a paused child outside it can only belong to a withdrawn
steer.
* fix(runtime): keep a replacement reusing a call ID out of the held steer
interrupted_children stores call IDs, and child() can replace a closed gate under the same ID. The replacement then looked held by an earlier delivered steer, so a withdrawn steer left it paused forever in a replaced turn. Drop the ID when its gate is replaced.
wait_tool reused the name gate for its pause loop, so every parallel task
returned the last child's result id and its done callback closed that
child's gate. The message reducer then dropped all but one pending result,
and the model was told that a running subagent had been interrupted.
Rename the loop variable so each call keeps its own gate.
* feat(runtime): add Queue and Steer for active Web runs
* style(frontend): format Queue and Steer controls
* fix(runtime): retain user Steer controls and order active inputs

serialize_lc_object() passed floats through unchanged, so a non-finite
value (NaN/inf/-inf) survived serialization and broke the two display
paths that share it with opposite JSON policies: the SSE wire
(format_sse / Redis bridge use the lenient default and emit bare
NaN/Infinity tokens the langgraph-sdk/useStream decoder rejects,
breaking the live stream) and the REST surface (Starlette JSONResponse
uses allow_nan=False and raises, turning a thread read into HTTP 500).
Non-finite floats reach the serializer from ordinary runtime data:
json.loads("1e400") yields inf for a tool parsing external JSON, a
provider logprob of -inf for a zero-probability token, or a divide-by-
zero ratio. They round-trip inside Python and checkpoint persistence and
only fail at the JSON boundary.
Normalize non-finite floats to None and recurse into model_dump()/dict()
output so nested values (e.g. a message's response_metadata) are
normalized too. This is a display/wire normalization only; persisted
checkpoint state is never routed through this serializer. Finite floats
are unchanged.

* fix(runtime): present outputs before a loop wrap-up and explain step-limit stops
Loop-detection warnings now ask the agent to present the files it already
created in /mnt/user-data/outputs before its final answer, when
present_files is available.
A run that exhausts recursion_limit now ends with stop_reason
recursion_capped and a plain message that lists outputs it created but
did not present. An active goal stands down without an evaluator call.
The /wait error envelope keeps the GraphRecursionError name, and IM
channels reply with the step-limit message instead of a generic failure.
* docs(changelog): note run-end delivery and step-limit stops (#7588)
* test(runtime): stop pinning LangGraph's step count in the step-limit test
The produced paths and the message already follow the observed model
calls, so the exact count only pinned LangGraph's per-step accounting.
Also note on the step-limit goal branch that its caller passes no
evaluator factory, so it has to stay ahead of the evaluator section.

* fix(workspace): don't infer created or deleted files from truncated snapshots
A bounded workspace scan stops at max_scanned_files and marks the snapshot
truncated. Absence from such a snapshot is unknown, so creation is only
inferred from a complete before snapshot and deletion only from a complete
after snapshot. get_changed_paths() is the single filter for the summary,
text capture and output-delivery detection.
The scanner now walks subdirectories in sorted order so the truncation
boundary is reproducible across the before and after scans, and the docs
note that the budget is consumed root by root (workspace before outputs).
Supersedes #5231.

* refactor(skills): keep allowed-tools as compatibility metadata
* docs(skills): align current guides with agent tool authority
* test(skills): simplify authority regressions and sync Korean docs
* fix(channels): run each IM message once across instances, restarts and late redeliveries
Inbound IM messages were deduplicated only by the 10-minute inbound dedupe
store (#7103). Discord direct messages had no key at all, a Discord thread
reply got an instance-dependent key, a Discord thread was created before
dedupe ran, a redelivery past the window started a second run, and two
instances racing on a conversation's first messages bound it to two
threads.
- Discord messages are keyed (discord, guild_id or "dm", posting channel,
message_id); the posting channel is the same on every instance.
- MessageBus.claim_inbound lets an adapter record the manager's dedupe key
before a side effect; Discord claims it on the Gateway loop before
_create_thread, marks the published message dedupe_claimed, and gives the
claim back when the message is never committed.
- runs.wait / runs.stream / runs.create send an Idempotency-Key derived from
the dedupe key, and keyed human message ids are uuid5 of it (a uuid4 per
attempt made every keyed retry a 409). A reused run's status-only /wait or
stream gap is resolved to this message's own turn via threads.get_state;
409s about the message's own keyed run keep the key instead of reading as
a busy thread; an ended reused GitHub run gets no follow-up watcher.
- A conversation's first thread binding is claimed insert-if-absent
(claim_thread_id on channel_conversations and channel_thread_bindings);
the loser adopts the winner and deletes the empty thread it minted.
/new and /agent use still rebind.
Docs: IM_CHANNEL_CONNECTIONS.md, CONFIGURATION.md, channels AGENTS.md,
CHANGELOG (en/zh).
* fix(channels): give back Discord dedupe claims for messages never processed
Review round 1 on #7104. A Discord claim records the manager's dedupe key
before the message is queued, so every path that drops the message unrun
must release it, or a peer refuses the redelivery for the rest of the TTL:
- The hand-off task releases the claim on cancellation too (stop() drains it
while it resolves the connection identity), via await_drained so the
cancellation still propagates.
- ChannelManager._discard_pending_inbound releases the key of a claimed
message that shutdown drops from the queue, after the grace period and on
a cancelled shutdown.
- The adapter tracks claims until they are committed. A release refused
because stop() already closed cross-loop intake, or a hand-off cancelled
before it ran, leaves the claim tracked, and stop() releases it last.
* fix(gateway): keep IM run idempotency stable when /new rebinds the conversation
Review round 2 on #7104. The Gateway scoped every Idempotency-Key by owner
and thread. /new rebinds an IM conversation to a fresh thread, so a late
redelivery of a message admitted on the old thread was requested on the new
one, got a different scoped key and started a second run.
- Keys from trusted internal callers (the IM channel manager) are scoped by
owner only (`internal-run:` prefix); browser and API keys keep the
owner-and-thread scope (`http-run:`).
- A key that resolves to a run of another thread or user raises
RunIdempotencyKeyMismatch, a RuntimeError subclass so in-process launchers
see the same type, and start_run answers it with 409 "Idempotency-Key
already used with a different request" instead of a 500. The channel
manager already treats that 409 as the message's admitted run.

* feat: support client context capabilities
(cherry picked from commit b7c223f9415dcd545cbe05a5f5a6e47073a42d68)
[Totoro-qaq: resolved onto main. The persisted-reminder middleware hunks and their tests are dropped (delivery is redesigned in a follow-up); the RunCreateRequest description moved to app/gateway/run_models.py.]
* fix: address client context review comments
(cherry picked from commit bce6da6b819228eda58e887872720b6f9b5fab69)
[Totoro-qaq: middleware hunks dropped with the redesigned delivery.]
* feat(agents): deliver client context as a request-scoped data block
The cherry-picked #3106 put context.client into the persisted first-turn
reminder, with change detection and a "not provided" clear marker. Main
has since moved the date reminder to a SystemMessage, made request-scoped
context (the project block, #5443) request-only, and agents/AGENTS.md now
requires user-influenced values to ride the HumanMessage data channel,
never system text.
Render runtime.context["client"] on every model call in
DynamicContextMiddleware.wrap_model_call/awrap_model_call as one hidden
HumanMessage right after the leading SystemMessages, where DurableContext
puts its data. It is never a state update and never flagged
dynamic_context_reminder, so nothing is checkpointed, summarized or
replayed, and a run without a client gets no block. An unchanged client
keeps the previous request as the next request's prefix.
The renderer sanitizes again (direct graph callers bypass the Gateway),
html-escapes values and frames them with frame_untrusted_text: the same
--- BEGIN/END USER INPUT --- boundary the user's own turn and the MCP task
notification get. The lead prompt treats everything outside those markers
as framework data, so unframed values would rank above the user's own
text; framed, context.client can say nothing the same caller could not
already say in input.messages. client_context joins _BLOCKED_TAG_NAMES so
a forged block in user input or a tool result is escaped, and one static,
value-free sentence in the lead prompt names the block as untrusted hints,
never instructions, permissions or identity. The now unused empty-context
marker is removed.
* fix(gateway): log dropped context.client fields without values
A run request is never rejected over context.client: unknown fields,
nested values and malformed entries are silently dropped, the same
leniency as the other context keys. That left no signal when a custom
client sent something the Gateway ignored (review on #3106).
Route both the config.context.client and the body context.client paths
through one helper that emits a debug line whenever sanitizing changed
the value. Like the malformed client_timezone branch, the line carries no
values; unlike client_timezone, client.name and preference strings are
free caller-controlled text, so they are never logged, not even
sanitized. A clean client, an explicit null or an absent key logs
nothing.
Tests also pin the config-only path (sanitized before the early return)
and the end-to-end start_run admission: the sanitized client reaches
config["context"] and never configurable.
* fix(runtime): bound numeric client context preferences
String preferences are capped at 200 characters, but integers were kept
at any size. A JSON body may carry integers of up to 4300 digits, so 32 of
them rendered a block of about 138,000 characters, re-sent on every model
call of the run. In-process callers could also pass an int past the str()
digit limit, which failed the model call, or a number subclass with its
own __str__.
Keep integers within JavaScript's Number.MAX_SAFE_INTEGER, the range a
browser client can send exactly, and coerce numbers to plain int and
float.
* docs(api): describe client context as advisory request-scoped hints
The cherry-picked section described a hidden reminder that no longer
exists. Document what a custom client can rely on: the allow-list and its
limits (strings, the integer range, and only the first 32 entries of each
map), debug-level logging of dropped fields, runtime-only forwarding, and
delivery as a per-request user-role block, framed like user input, rather
than system text or thread history.
Only top-level context.client is documented. An explicit
config.context.client is sanitized for the run as well, but the run record
keeps the caller's config as sent, so it is not offered as an alternative.
It also answers the #3106 review: capabilities and preferences are
advisory hints, not enforcement, which belongs outside the model; name is
informational and never for authorization; the same object should be
sent on every run to keep the cached prefix stable; subagents and
embedded DeerFlowClient runs do not receive it, and server-started runs
(schedules, IM channels, GitHub agents, MCP notifications, extensions
unless the plugin passes one) carry none.
* fix(context): declare client delivery and keep client out of configurable
The request-only <client_context> block is model-visible, so
DynamicContextMiddleware now declares its delivery and the sanitizer's
limits in release_policy_parameters(); runs before and after this change
no longer share a policy fingerprint.
build_run_config copies body.config['configurable'] verbatim and
configurable is persisted with checkpoints, so a client placed there is
dropped instead of being stored raw. Client context stays runtime-only.
Document context.client in the README and in the middleware guide.
* fix(context): apply the PII redaction policy to the client block
DynamicContextMiddleware adds the <client_context> message inside the
outer PiiRedactionMiddleware, and the hidden message is not re-sanitized,
so with pii_redaction enabled a preference such as an email address
reached the model verbatim while the same address in the user turn was
redacted. Pass the rendered block through the shared redact_text seam
with this middleware's app_config.pii_redaction, and declare the setting
in release_policy_parameters().
* fix(context): keep client hints out of stored run config

run_agent() only refreshed runs.model_name when the request named a model,
and it read the effective model from agent.metadata, which compiled
LangGraph graphs do not have. The default model (no model_name requested)
and fallback models were therefore never persisted. Use the effective
model that lead-agent assembly already resolves, and write only when it
differs from the stored value.

* fix(compaction): reject manual compaction of threads with pending execution
A thread paused at a static breakpoint (interrupt_before=["tools"]) keeps its
pending node send in the checkpoint's __pregel_tasks channel. The compaction
write goes through the state-mutation graph, which schedules no tasks, so
LangGraph drops the pending send ('Ignoring unknown node name tools in pending
sends') and a resumed run finishes success without ever executing the tool.
Fail closed: detect a non-empty __pregel_tasks in the raw checkpoint tuple
inside compact_thread_context and raise ContextCompactionPendingWork, mapped
to HTTP 409 by the compact route. The reservation (reserve_checkpoint_write)
already serializes this check against runs and other checkpoint writers, and
the write still forks from the exact head that was read.
Adds dual-mode (full/delta) regression tests: the rejected compaction leaves
checkpoint id, next and pending task ids untouched, and resuming afterwards
executes the pending tool exactly once; idle threads still compact.
