fix(mcp): preserve server binding history across gateway workers (#6617)
* fix(mcp): preserve server binding history across gateway workers

A peer Gateway worker could keep a stale pooled session after another worker deleted and identically re-added a stdio server, because the final effective MCP slice matched the revision it had already applied.

Record a per-server lifecycle generation in the shared extensions config and consume it in the reader, discovery claim, and committed handoff so an observed generation change force-rebinds only the affected server. Legacy configs derive a stable in-memory token; deletions leave permanent tombstones.

* fix(mcp): fail closed on an invalid mcpLifecycle instead of retrying

An unverifiable mcpLifecycle made initialize_mcp_tools() unpublishable, so get_cached_mcp_tools() retried discovery forever and could keep respawning stdio servers. Abort discovery on an invalid ledger after conservatively retiring local MCP state; a fixed config recovers on the next call.

Also documents the rolling-upgrade prerequisite: cross-worker ABA detection requires configuration writes to go through a lifecycle-aware writer.

* refactor(mcp): share stdio fingerprinting across lifecycle paths

Reuse lifecycle._stdio_fingerprints from the applied-revision builder so the connection-identity rule has a single implementation, and move the unusable-server diagnostic into the shared helper.

Add a regression proving the Gateway Skills writer preserves mcpLifecycle byte-for-value, and document that DeerFlowClient.update_mcp_config can raise RuntimeError after the config was committed.

* docs(mcp): condense lifecycle guidance under the AGENTS chain limit

The effective mcp/AGENTS.md chain was 15 bytes under the 98,304-byte CI hard limit, so the standalone cross-worker lifecycle bullet pushed it over. Fold the mcpLifecycle and rolling-upgrade facts into the existing selective-reconciliation bullet and condense it, keeping the chain under the limit while preserving the contract.

* docs: trim inherited agent guidance below CI size limit

fix(scripts): reject local BIND_HOST values nginx would misread (#6635)
* fix(scripts): reject local BIND_HOST values nginx would misread

nginx-local-conf.sh checked only for address and hostname characters.
BIND_HOST=0 rendered `listen 0:2026;`, which nginx resolves to 0.0.0.0 and
binds on every IPv4 interface, and 1.2.3 bound 1.2.0.3. Values nginx rejects
outright ([[fd00::1]], -foo) passed the serve.sh preflight and failed only
after stop_all had torn down the running stack.

Accept exactly a dotted-quad IPv4 address, an IPv6 address (brackets
allowed around IPv6 only), or an RFC 1123 hostname. Returning to the
loopback default removes a temp/nginx.local.conf rendered for an earlier
value, and stop_all now says why it can quit a rendered-config nginx
through the tracked config; a test pins the shared pid directive.

* docs(changelog): reference #6635

* docs(changelog): match the zh reference spacing

* fix(scripts): check every BIND_HOST hostname character before splitting labels

read -r -a stops at the first newline, so is_hostname validated only the
first line of a value like $'localhost\nbad' and the rest reached the
rendered listen directive. Check the allowed characters across the whole
value first, and cover multi-line, CR and tab values for each validator.

fix(lark): publish the CLI runtime files atomically (#6618)
* fix(lark): publish the CLI runtime files atomically

install_shim wrote the shim, the launcher and the runtime marker with a
truncating open. The sandbox chmods the launcher 0o755 and execs it, so a crash
mid-write left an executable fragment, and the marker is parsed as JSON. Publish
through a temporary file plus os.replace, as the storage backends already do.

* style: drop the unused import ruff flags

* fix(lark): publish runtime permissions atomically

Set file permissions on temporary files before os.replace() to ensure
the launcher, shim, and runtime marker are atomically published with
correct permissions (0o755 for executables, 0o644 for the marker).

This addresses reviewer feedback from PR #6591:
- Permissions are now set before the atomic replace operation
- Prevents brief window where files have incorrect permissions
- The runtime marker now has mode 0o644 instead of 0600 (mkstemp default)

Also updates test_lark_shim_atomic.py:
- Fixes test_atomic_helper to match new function signature
- Adds test_install_shim_publishes_correct_permissions to verify
  launcher/shim (0o755) and marker (0o644) permissions

fix(workspace-changes): keep the package importable as a first import (#6602) (#6608)
`workspace_changes/api.py` imports `deerflow.runtime.user_context` for the
AUTO sentinel (#6282). Importing that submodule runs the runtime package init,
which imports `.runs` -> `worker` -> `deerflow.workspace_changes` back for
`capture_workspace_snapshot` and friends, so importing `.api` as the package's
first statement failed with ImportError while those names were still unbound.

Resolve the re-export lazily via a module-level `__getattr__`, the pattern
`deerflow/subagents/__init__.py` already uses.

feat(dev): add a two-Gateway multi-instance harness script (#6613)
* feat(dev): add a two-Gateway multi-instance harness script

There was no way to run the deployment.multi_instance topology locally:
scripts/serve.sh pins one Gateway to port 8001, the local nginx config has a
single upstream, and getting two processes past the multi-instance startup gate
needs Postgres, Redis, a shared DEER_FLOW_HOME, shared auth secrets and a
per-process DeerMem retrieval index by hand.

scripts/dev_multi_instance.sh (make dev-multi / dev-multi-check /
dev-multi-down) starts throwaway Postgres and Redis containers on loopback,
renders a config from the developer's config.yaml (or config.example.yaml),
and runs Gateway A on 8001 and Gateway B on 8011 with one shared home, one
copy of extensions_config.json and generated AUTH_JWT_SECRET,
DEER_FLOW_INTERNAL_AUTH_TOKEN and DEER_FLOW_CREDENTIALS_KEY values, plus an
optional round-robin nginx on 2027. B starts after A answers /health: Alembic
migrations are advisory-locked, but the LangGraph checkpointer/store setup()
that follows is not.

scripts/dev_multi_instance.py holds the testable parts: the config overlay
(neutralizing and reporting settings the gate refuses), the secrets file, the
nginx config, and `check`, which automates the scriptable cross-instance
acceptance checks: readiness with stream_bridge ok, A-issued sessions and the
internal token accepted by B, thread/upload/artifact visibility, a skill
toggle seen by B, nginx balancing, and SSE join on B with Last-Event-ID resume
on A. Tests pin that the rendered config passes the real
_enforce_postgres_for_multi_worker gate.

* docs(changelog): link the two-Gateway harness entries to #6613

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(dev): keep the multi-instance harness inside its own state

Address review findings on the two-Gateway harness (#6613):

- Containers carry a deerflow.harness.state-dir label; up/down remove only
  containers of their own state dir and refuse those of another checkout or
  DEERFLOW_MI_STATE_DIR instead of force-removing them.
- Containers are removed with `docker rm -f -v`, so the anonymous volumes
  the postgres and redis images declare no longer leak on every up/down.
- `up` installs an EXIT trap once it starts containers, so any later failure
  (including B's port being taken after preflight) tears down A and both
  containers; start_gateway returns failures instead of exiting the script,
  and the Gateway is disowned so stopping it prints no job notice.
- The overlay removes any checkpointer section (a postgres one would write
  checkpoints and the Store into the developer's database), points an
  explicit sandbox.ownership and a Redis checkpoint_cache at the harness
  Redis (keeping ownership timing), drops DeerMem storage_path (both
  spellings) and the blob_storage root so data lands in the harness home,
  gives a local AIO sandbox a state-dir-specific container_prefix, and
  reports a non-DeerMem memory backend it keeps sharing.
- nginx paths are rendered as quoted string literals ('$' and control
  characters are refused), so a state dir with spaces works.
- `check` skips the run-based SSE check when model discovery did not
  succeed, unless --with-llm, and enforces the SSE time budget per raw line
  so heartbeat-only traffic cannot hold it open.

fix(mcp): stop persisting URL-sourced ResourceLink blocks and heal bricked threads (#6606)
* fix(agents): sanitize persisted URL content blocks before model calls

Threads whose checkpoints carry URL-sourced file blocks (written before
the MCP conversion-layer fix) fail every model call at serialization: the
Chat Completions translator rejects any file block carrying a url, and the
error handler answers each later turn with a non-retriable fallback. Add a
read-time sanitizer that rewrites those blocks in the model-bound request
view only, so poisoned threads heal on their next turn with no migration
and no user action.

- ModelContentCompatibilityMiddleware wraps the model call (sync and
  async) and rewrites ToolMessage list content: URL-sourced file blocks
  become "[Resource ({mime or unknown type}) available at {url}]" text
  blocks, and image blocks whose scheme is not http/https/data get the
  same placeholder. Fetchable image URLs, base64 payloads, text, and
  non-ToolMessage messages pass through. The rewrite is order-preserving,
  idempotent, and never writes state or mutates checkpoints, so artifact
  capture and other state readers keep seeing the original blocks.
- Register on all three chains that replay checkpointed ToolMessages:
  build_middlewares (lead; outer of the MODEL_PHYSICAL extension anchor so
  its final-request guarantee holds), the SDK factory
  _assemble_from_features (new step 13a; docstring updated and its stale
  omission of TokenBudgetMiddleware fixed), and
  build_subagent_runtime_middlewares (after DurableContext/summarization,
  before the date/coalescer tail).
- Subagent coverage verified by tracing every subagent agent-creation
  site: executor.py _create_agent is the only caller of
  build_subagent_runtime_middlewares and serves both the task tool and the
  durable batch worker (SubagentRuntime itself only carries dependencies),
  and a wiring test now asserts the middleware is present in that
  builder's output; the lead and factory chains gained the same wiring
  assertions.
- Update the chain-order contract tests for the new slot: full-chain
  order, loop-detection adjacency, custom loop-detection tail positions,
  and the subagent chain count (22 -> 23).

* fix(mcp): stop emitting URL-sourced file blocks from ResourceLink results

MCP ResourceLink conversion produced a URL-sourced file content block for
every non-image link, which LangChain's Chat Completions translator rejects
at serialization time. Once such a block was checkpointed in the
ToolMessage, every subsequent turn of the thread failed at model-call time,
permanently bricking the conversation.

- Downgrade every ResourceLink that is not an http(s) image to a short text
  placeholder carrying the resource name, MIME type, and the
  already-virtualized URL, so host paths never leak and the model still
  learns a resource was produced and where it lives.
- Preserve each downgraded link as structured data in the tool-message
  artifact under resource_links (merged with structured_content when
  present) for artifact capture and future MCP Apps rendering.
- Keep http(s) image links as image blocks; embedded base64 payloads, text
  path rewriting, and the error-to-ToolException path are unchanged.
- Re-contract the file-migration tests to the new behavior and document
  the conversion contract in the MCP AGENTS.md.

* docs(middlewares): add ModelContentCompatibilityMiddleware to the chain inventory

Insert the read-time sanitizer at its actual lead-chain position (after the
token-budget guard, before the custom-middleware injection point) and renumber
the tail entries 34-39 to 35-40.

* fix(agents): rewrite file blocks on url key presence, not truthiness

langchain-core's OpenAI translator raises for ANY file block carrying a
url key — an empty string or None included — so the read-time sanitizer
must not let such blocks through just because the value is falsy. A
persisted block with url="" or url=None would still brick every later
model call in the thread.

- Gate the file-block rewrite on "url" in block instead of a truthiness
  check; a non-empty string URL keeps the
  "[Resource (mime) available at url]" placeholder, while an empty or
  None URL gets a location-less "[Resource (mime)]" placeholder, so no
  unusable location is advertised to the model.
- Pin both shapes with new middleware tests (url="" and url=None file
  blocks are both rewritten to text). The image branch is unchanged: an
  empty-image case fails provider-side with a 400, not a bricked thread.

* fix(mcp): keep data URIs out of model text and resource_links

A data: scheme ResourceLink fell into the generic placeholder branch,
inlining megabytes of base64 into the model-visible text and into
resource_links, which is checkpointed state — against the repo policy
that data:/blob: URIs never enter state.

- Special-case data: links in _convert_call_tool_result: the
  model-visible placeholder becomes "[Resource: name (mime) embedded
  inline]" and the raw URI is not added to resource_links at all, so the
  payload can neither bloat the context window nor persist in the
  checkpoint.
- Pin the behavior with a conversion test asserting both the placeholder
  wording and the absence of the payload/URI from every emitted block and
  the artifact.
- Add the missing passthrough pin for an HTTPS:// uppercase-scheme image
  link: scheme matching is case-insensitive, so the link stays an image
  block (the block's URL validation normalizes the scheme to lowercase).

* fix(tools): consume resource_links in extract_artifacts_from_result

The MCP conversion layer preserves downgraded ResourceLinks as
{"name", "uri", "mime_type"} entries under the tool message
artifact's resource_links key, but the artifact extractor only read
structured_content — a result whose only artifact signal was
resource_links produced no entries and the file silently vanished from
the artifacts panel.

- Add a fourth extraction path: each resource_links entry becomes a file
  artifact entry, reusing _is_referenceable_url like the
  structured-content and content-block paths, so data:/blob: and other
  unresolvable URIs stay rejected per existing policy. The entry is named
  after the link when a name is present, falling back to the URI's final
  segment; a string mime_type is carried through.
- Integration-test a result whose only signal is resource_links, plus the
  referenceability gate (data:, ui://, and absolute-path URIs in one
  artifact).

* docs(mcp): update the ResourceLink conversion contract bullet

Mention the new artifact-registry consumer and the data: special case so
the bullet stays accurate: uppercase http(s) schemes match
case-insensitively, data: URIs get the embedded-inline placeholder and
are dropped from resource_links, and extract_artifacts_from_result turns
resource_links into registry entries through the shared
referenceability gate.

* refactor(tools): add the canonical resource placeholder formatter

Both the MCP conversion layer and the read-time
ModelContentCompatibilityMiddleware downgrade model-incompatible resource
references to a text placeholder, but each built its own literal. Extract
the single formatter they will share so a thread healed at read time shows
the model the same placeholder shape a fresh conversion produces; the name
segment is optional because persisted content blocks carry no resource name.

* fix(mcp): keep host paths out of ResourceLink placeholder text

Review follow-up on the ResourceLink conversion contract. The placeholder
embedded the resolved URL unconditionally, so a link outside the user-data
tree (or converted without thread context) leaked a raw host path — a
file:// URI or bare filesystem path — into model-visible text, violating
US-16. Compute the resolved URL's scheme and withhold the location segment
when it spells out a host filesystem location (empty scheme, file, or a
single-letter Windows drive scheme); virtual paths and remote schemes keep
their location. The unresolved URI still lands in the artifact channel,
which the model never sees.

- add _model_visible_link_location gate and route the generic placeholder
  through it, re-contracting the outside-user-data and no-context tests to
  the location-less shape and pinning the Windows-drive case
- treat blob: like data: as non-referenceable inline input: drop its raw
  URI from checkpointed resource_links and emit the location-less
  placeholder instead of the mismatched 'embedded inline' wording, and fix
  the comment that claimed blob: was already excluded
- replace every inline placeholder f-string in the ResourceLink branch
  with the shared resource_placeholder_text formatter so the conversion
  layer and the read-time middleware emit byte-identical shapes; data:
  links now render in the canonical location-less form
- sync the ResourceLink conversion contract bullet in mcp/AGENTS.md and
  the _convert_call_tool_result docstring with the host-path suppression
  rule and blob: handling

* fix(agents): sanitize URL content blocks on any message role

Address the second-pass review of the request sanitizer with two
changes that share the same code path.

- Adopt the canonical resource_placeholder_text formatter from
  deerflow.tools.resource_placeholder instead of the module-local
  placeholder helpers, so the read-time rewrite and the MCP conversion
  layer emit byte-identical placeholder text from one definition.
- Widen the rewrite from ToolMessage-only to every request message with
  list-form content. User uploads are verified to produce base64 blocks,
  but imported or cross-client history can carry a URL-sourced file
  block on a HumanMessage or AIMessage, and the Chat Completions
  serializer rejects such a block regardless of the role carrying it.
  The rewrite stays request-view-only: state and checkpoints are never
  mutated, and base64/file-id blocks and string content pass through
  untouched on any role.

* docs(agents): state the ModelContentCompatibility placement contract

The comment above the registration claimed the sanitizer sits just
before Clarification. In the lead chain it is actually followed by the
custom/extension injection point and the whole terminal tail
(terminal-response, finish-reason, and the always-last
ClarificationMiddleware). Describe the real contract: after every
built-in content transform, before extension injection and the
terminal tail.

* docs(middlewares): clarify provenance stamps for request-view-only rewrites

The message-provenance rule read as if every rewrite needs a
provenance_kwargs stamp. Add one line noting the exception: rewrites
that only modify the model-bound request view and never enter state
need no stamps, citing InputSanitizationMiddleware,
DanglingToolCallMiddleware, and ModelContentCompatibilityMiddleware as
precedents.

* fix(agents): keep host paths and data URIs out of healed placeholders

The read-time ModelContentCompatibilityMiddleware rewrote URL-sourced
file blocks and non-fetchable image blocks into placeholders that
inlined the block's URL verbatim. Pre-fix checkpoints — exactly the
threads this middleware exists to heal — can carry a file:// URI, a bare
or Windows host path (links that never resolved to virtual paths), or a
data: URI embedding megabytes of base64, so healing leaked deployment
filesystem layout into prompts (US-16) and could inject the whole inline
payload into model-visible text.

The conversion layer already suppresses those forms via
_model_visible_link_location. Move that gate into the shared
deerflow.tools.resource_placeholder module as model_visible_location
(now also collapsing data:/blob: URIs) and route both middleware
branches through it, so both layers apply identical suppression rules
with one definition. Conversion behavior is unchanged: its data:/blob:
branch short-circuits before the gate, and the gate covers those schemes
for defense in depth.

- resource_placeholder.py gains model_visible_location alongside the
  shared formatter; mcp/tools.py drops its private copy and imports it.
- The middleware's file and image branches pass the URL through the gate
  before building the placeholder; module docstring documents the rules.
- Tests: gate unit tests (virtual/remote visible; file://, bare/Windows
  host paths, data:/blob: withheld) and middleware regression tests
  pinning that a pre-fix data: payload, file:// URI, and Windows drive
  path heal to location-less placeholders.
- AGENTS.md bullets in mcp/ and middlewares/ state the shared gate.

* fix(agents): downgrade malformed image URLs instead of raising in the sanitizer

The read-time ModelContentCompatibilityMiddleware gated persisted image
blocks on urlparse(url).scheme, but urlparse raises ValueError on
structurally invalid URLs — a bad IPv6 literal, invalid netloc
characters — instead of returning an unusable scheme. Pre-fix
checkpoints and imported history can carry exactly those URLs, and the
block stays in the checkpoint, so every later model call in the thread
raised again: the sanitizer re-bricked the very threads it exists to
heal, only with a framework-side exception instead of the langchain
serialization error.

Catch ValueError and treat the URL as non-fetchable, so the block
degrades into the same text placeholder as any other unresolvable
scheme (the shared model_visible_location gate already swallows
ValueError, so the location segment is withheld as well).

- wrap the image branch's urlparse call in try/except ValueError and
  fall back to an empty scheme, keeping http/https/data pass-through
  behavior unchanged for well-formed URLs
- add a regression test pinning that an image block with a bad IPv6
  literal heals to the location-less placeholder without raising

* fix(tools): dedupe artifact refs across extraction sources

One downgraded ResourceLink produced two registry entries: the typed
resource_links channel added an entry for the URI, and the free-text
scan over the conversion layer's placeholder text — which embeds the
same virtual path or remote URL — matched it again. The two handles
pointed at one resource, spent double of the render budget, and showed
the model two handles for a single artifact.

extract_artifacts_from_result now tracks seen real_refs across all
sources and keeps only the first entry per ref. Extraction order makes
the typed sources (structured content, resource_links, content blocks)
win over the free-text scan, so the surviving entry keeps the link's
display name and mime type.

- route all six entry-producing sites through a local _add_unique
  helper keyed on real_ref; per-source behavior is unchanged
- document the cross-source dedup in the function docstring
- add a regression test covering a virtual-path and a remote-URL
  placeholder together with their resource_links entries

* docs(mcp): state the intentional data: image downgrade asymmetry

The conversion layer downgrades image/* data: ResourceLinks to
location-less text placeholders, while the read-time middleware lets
persisted data: image blocks pass through to the model. The two
contracts looked contradictory but are deliberately layered: the
conversion layer keeps new inline payloads out of checkpointed state,
and the middleware only preserves blocks already occupying one.

- mcp/AGENTS.md's ResourceLink conversion contract and the conversion
  comment in mcp/tools.py now state the image/* data: downgrade and
  why it differs from the read-time pass-through
- middlewares/AGENTS.md's ModelContentCompatibilityMiddleware entry
  states the symmetric read-time rule
- pin the behavior with an image-mime data: ResourceLink conversion
  test (location-less placeholder, nothing in the artifact channel)

* docs(backend): compact AGENTS.md guidance to fit the chain byte budget

The branch's new contract bullets pushed the middlewares and mcp
effective AGENTS.md chains past the 98304-byte AG002 hard limit (the
sandbox/subagents chains on main were already over it). Compact the
guidance without dropping contracts:

- middlewares item 34 points at the MCP ResourceLink conversion
  contract and the module docstring instead of restating both
- the mcp ResourceLink conversion contract bullet is tightened
- backend/AGENTS.md merges the File Upload and Context Summarization
  bullet sprawl, folds the stray ATX test note into the upload outline
  rule, drops the Nginx routing block the root guide already covers,
  merges the duplicate MCP-task pointer bullet, compacts Vision
  Support, and scopes the Project Structure tree to the backend
  subtree (the root guide maps the full repo)

* fix(agents): gate the file-URL downgrade on provider support and neutralize placeholder metadata

Two review findings on the read-time sanitizer:

- The file-block downgrade ran for every provider, but only Chat
  Completions rejects URL-sourced file blocks: the OpenAI Responses API
  (input_file file_url) and Anthropic (document url source) accept
  http(s) document URLs, so a persisted block created for those
  providers lost its document from the model request. Keep the block
  when the selected model serializes http(s) file URLs natively; every
  other URL shape (non-http schemes, empty/None, malformed) still
  degrades to the placeholder.
- The placeholder interpolated persisted MIME/location metadata
  verbatim, but the middleware runs after the input/tool-result
  sanitization passes and historical URL blocks never went through them
  (non-text content is left untouched), so values carrying
  <system-reminder>-style tags or user-input boundary markers reached
  the model raw. Route the interpolated metadata through the shared
  neutralize_untrusted_tags guard in both the file and image branches.

Tests: provider gating (Responses/Anthropic preserve, Chat Completions
still downgrades, non-http and malformed URLs downgrade even for
capable providers) and metadata neutralization (injection tags
HTML-escaped, boundary tokens neutralized, file and image branches).

* fix(tools): require a directory boundary before exposing virtual locations

model_visible_location admitted any URL starting with the virtual
prefix, so a sibling like /mnt/user-data-backups/ops/private/report.pdf
was treated as a virtual path and its host location reached
model-visible placeholder text — defeating the US-16 host-path
suppression the gate exists for. Require the exact virtual root or a
slash-delimited descendant; siblings now collapse to the location-less
placeholder like any other host path. Both the file and image
downgrade branches share the gate, and the conversion layer applies
the same rules to fresh results.

Regressions: gate unit tests (exact root and descendants stay visible;
/mnt/user-data-backups and /mnt/user-database siblings withheld) and
middleware tests pinning the location-less placeholder for both
branches.

* docs(agents): scope the placeholder artifact-visibility claim to the conversion layer

The module docstring claimed the healed placeholder keeps the location
visible to the artifact free-text scan and that the link survives in
the structured artifact channel — true for the conversion layer, whose
placeholders are checkpointed, but not on the healing path: the request
view never reaches artifact capture, and no resource_links entry is
created for a downgraded block. Spell out what actually happens here:
a referenceable original block (http(s) URL or absolute host path) is
still captured, from the capture-time scan of the state block rather
than the placeholder, while a non-referenceable one (file://, data:,
blob:) yields no entry and survives only in the untouched checkpoint.

test: route four unguarded symlink fixtures through symlink_or_skip (#6619)
* test: route four unguarded symlink fixtures through symlink_or_skip

`tests/support/symlinks.py` was added in #5414 so suites that need a real
symlink skip cleanly when the host cannot create one. On a stock Windows host
(no Developer Mode, not elevated) `Path.symlink_to` / `os.symlink` raise
`OSError: [WinError 1314]`, and four fixtures still called them directly, so
they reported hard errors instead of skipping:

- tests/test_shared_reset_marker.py::test_marker_path_follows_a_symlinked_config
- tests/test_view_image_middleware.py::test_host_image_copy_is_scoped_to_current_user_and_thread
- tests/test_review_skill_package_tool.py::test_review_skill_package_rejects_symlink_planted_in_callers_outputs
- tests/test_channel_file_attachments.py::TestInboundFileSandboxPerms::test_make_inbound_file_sandbox_readable_swap_after_lstat_does_not_follow_symlink

These were the only symlink-related failures in a Windows run of the full
backend suite; the other bare symlink call sites there are already guarded by a
`skipif` or a `try/except OSError`. The view-image test plants its symlink
after its scoping assertions, so those still run before the skip. The
inbound-attachment test stages a symlink from inside a monkeypatched `os.lstat`
to exercise a TOCTOU race; a host that cannot create a symlink cannot stage
that race at all, so skipping is the only honest outcome.

fix(security): add DEER_FLOW_CREDENTIALS_KEY and wire the channel credentials cipher (#6611)
* fix(security): add DEER_FLOW_CREDENTIALS_KEY for at-rest credential encryption

There was no at-rest encryption key. ChannelCredentialCipher had no
production caller: the channel service, the scheduled-task notification
outbox and the channel-connections router all built
ChannelConnectionRepository without a cipher, so store_credentials refused
(RuntimeError) and get_credentials always returned None.

- New harness module deerflow.config.credentials_key: env-only
  DEER_FLOW_CREDENTIALS_KEY (comma-separated Fernet keys; first encrypts,
  all decrypt via MultiFernet), CredentialsCipher with encrypt_text /
  decrypt_text / rotate_text, a fernet:v2: prefix with legacy fernet:v1:
  values still readable, and get_credentials_cipher() as the process-wide
  entry point. Malformed keys are refused without echoing key material.
  Without the variable a single instance generates
  {base_dir}/.credentials_key. Never derived from AUTH_JWT_SECRET.
- New deerflow.config.secret_file.read_or_create_secret_file: O_EXCL
  create (0600) plus read-back with a bounded settle window, shared by
  .credentials_key, .jwt_secret (fixes two replicas cold-starting on a
  shared volume keeping different JWT secrets) and the managed-model key.
- ChannelCredentialCipher now builds on CredentialsCipher (same
  constructors); the Gateway loads the cipher off the event loop at
  startup when channel_connections is enabled and passes it to every
  ChannelConnectionRepository. Undecryptable values stay "missing + warn".
- Startup gate: a malformed key stops startup in any topology; a declared
  multi-instance deployment with channel_connections enabled and no key
  is refused. Plain multi-worker shares the generated file and is allowed.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* feat(deploy): generate and inject DEER_FLOW_CREDENTIALS_KEY in Helm, compose and deploy.sh

- Helm: the app Secret generates a Fernet key (randBytes 32 translated to
  the urlsafe alphabet) and preserves it across upgrades via lookup like
  AUTH_JWT_SECRET; the gateway reads it through an optional secretKeyRef
  so a user-managed existingAppSecret without it still boots (the Gateway
  gate refuses only multi-instance deployments that store credentials).
  README, NOTES and values document backup, rotation and existingAppSecret.
- scripts/deploy.sh resolves the key shell -> .env -> persisted file ->
  generated, persisting it as $DEER_FLOW_HOME/.credentials_key (0600,
  noclobber/O_EXCL with read-back): the same file the Gateway generates in
  its runtime home, so either side's key is the one both keep.
- Both compose files pass DEER_FLOW_CREDENTIALS_KEY=${...:-} to the gateway.
- .env.example entry with a generation hint; README and CHANGELOG notes.

* fix(security): make abandoned secret-file replacement single-winner

A rename is last-writer-wins, so replicas that restart together and all
find the same abandoned empty secret file could each replace it and keep
a different value. The process that exclusively creates
<name>.replacing now owns the replacement, re-checks the file is still
empty, and publishes by renaming the claim over it; peers wait for that
value, bounded so a crashed replacer cannot block startup forever.

The multi-instance refusal ended with "or disable

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(security): never expose a secret file before its value is written

O_EXCL published the name before its content, so a creator that stalled
mid-write left an empty file a peer replaced after the settle window; the
resumed creator then returned a value nobody persisted, or deleted the
peer's valid file when its own write failed. Creators now write and sync
a private temporary file and hard-link it to the name, which fails if
the name exists; a failed creator only removes its own temporary file.
Filesystems without hard links publish through the same single-winner
<name>.replacing claim that replaces abandoned empty files, so creation
and replacement are serialized there.

* fix(models): recover an empty managed-model key when no catalog exists

An interrupted first save could leave an empty key file; every later save
then passed empty bytes to Fernet and the endpoint returned 503 until the
file was removed by hand. An empty key with no catalog encrypted nothing,
so it now goes through the secret-file recovery path; next to an existing
catalog it is still refused.

* fix(docker): pass the dotenv DEER_FLOW_CREDENTIALS_KEY through make docker-start

scripts/docker.sh runs Compose from docker/ without --env-file, so the dev
gateway's DEER_FLOW_CREDENTIALS_KEY=${DEER_FLOW_CREDENTIALS_KEY:-} entry
interpolated to empty and overrode the key the checkout .env supplied via
env_file. Export it from the dotenv like AUTH_TRUSTED_PROXIES.

test: fix two Windows-host failures (subprocess encoding, budget-boundary epsilon) (#6627)
* test: fix two Windows-host failures (subprocess encoding, budget-boundary epsilon)

- test_env_file: pin PYTHONIOENCODING=utf-8 in the stripped child env;
  without it the child writes stderr in the host's ANSI codepage while
  the UTF-8-mode parent decodes it, the reader thread dies on the first
  non-ASCII byte, and stderr comes back None;
- test_jina_retries: give the budget-cap assertion a 1e-9 tolerance —
  deadline = now + budget rounds, so the cap lands a few ulps above the
  exact 0.05 (observed 0.05000000000291038).

Fixes #6626

* test: pin both sides of the capture and use an uptime-proof budget tolerance

- test_env_file: the parent's capture decodes with the host locale when
  pytest runs without the Makefile's UTF-8 pins, so the child-side pin
  alone mirrored the crash rather than eliminating it. Pin the capture
  explicitly (encoding=utf-8, errors=replace, per the
  test_local_sandbox_encoding.py precedent) and carry both suite pins in
  the child env (PYTHONUTF8=1 + PYTHONIOENCODING=utf-8).
- test_jina_retries: the float error scales with loop-time magnitude
  (host uptime), not with 0.05; a 1e-9 absolute slack leaves a ~389-day-
  uptime flake window. Use a relative tolerance instead.

fix(runtime): drain staged-terminal runs on shutdown before checkpointer teardown (#6620)
* fix(runtime): drain staged-terminal runs on shutdown before checkpointer teardown

RunManager.shutdown() selected only pending/running records, but with an event
store a run stages its terminal status in memory and keeps finalizing: journal
flush, delivery receipt, workspace scan, the duration checkpoint write and the
deferred terminal commit, all while terminal_commit_pending is set. A Gateway
shutdown landing in that window did not await the run, so langgraph_runtime
could close the checkpointer before the duration write landed - the #3373
class the drain exists to prevent.

Drain those records too, using the existing _awaits_terminal_commit state that
_renew_leases already relies on; await them without cancelling (a cancel would
skip their terminal tail) and never overwrite their staged terminal status
with interrupted.

* fix(runtime): surface shutdown terminal finalizer failures

Cover timed-out staged terminal runs for both commit barriers and terminal outcomes. Log failed finalizers with their run ID, staged status, and traceback while preserving status and completing the drain.

fix(acp): resolve a bare agent command through PATH before spawning (#6598)
* fix(acp): resolve a bare agent command through PATH before spawning

`invoke_acp_agent` handed `acp_agents.<name>.command` straight to the ACP
SDK, which spawns it with `asyncio.create_subprocess_exec`. That API applies
no `PATHEXT` lookup on Windows, so a bare npm launcher (`npx`, `mcode`)
raised `FileNotFoundError` although its `.cmd` shim was on `PATH`. The
documented `command: npx` and `command: mcode` shapes could not start, and
the tool reported "was not found on PATH" for an installed launcher.

Resolve the configured command with `shutil.which` before spawning — the way
the MCP Python SDK normalizes stdio server commands — and keep the configured
value when nothing matches, so the existing install guidance still fires.

Fixes #6597

* fix(acp): resolve the ACP agent command off the event loop

`_resolve_agent_command` calls `shutil.which`, which stats the filesystem.
Calling it inline in the async `_invoke` tripped the strict BlockBuster gate
(`BlockingError: Blocking call to os.access`) for every command that resolves,
and would block the Gateway event loop in production.

Offload the lookup with `asyncio.to_thread`, matching the neighbouring
`_get_work_dir`, `_build_acp_mcp_servers`, and `_format_invocation_error`
calls.

The blocking-io anchor configured `command="test-agent"`, a name that resolves
nowhere, so `shutil.which` short-circuited before `os.access` and the gate
never covered the new call. Point it at `sys.executable` so the lookup is
really exercised, and cover the unresolvable-guidance branch end-to-end with a
new test.

Refs #6597

* fix(acp): keep the configured command in ACP remediation text

Review follow-ups on the PATH resolution:

- Only bare names are resolved. A configured path is interpreted by the spawn
  against the per-thread ACP workspace, so resolving it against the Gateway's
  working directory could pick a different file or hand the spawn a path that
  then fails.
- `_format_invocation_error` receives `agent_config.command` again. A command
  can resolve on PATH and still fail to launch (a broken shebang, for example),
  and reporting the resolved path made "was not found on PATH" false and
  dropped the `codex-acp` hint.
- The blocking-io anchor uses a bare name backed by a shim on a controlled PATH
  instead of `sys.executable`, which the bare-name scoping no longer resolves.

Tests: the pass-through assertion in
`test_invoke_acp_agent_uses_fixed_acp_workspace` pins PATH, and new coverage
covers the bare-name scoping and the spawn-failure message.

Refs #6597

* docs(acp): correct the path-resolution rationale

A configured path is resolved by the spawn in its own process, so the
pass-through reason must not claim it is resolved against the ACP workspace:
that only holds on POSIX, while Windows resolves a relative executable against
the calling process's directory. State the platform-neutral reason instead.

Refs #6597

* fix(acp): resolve the launcher against the agent's own PATH

The ACP SDK merges acp_agents.<name>.env over its inherited environment at spawn time, so a configured PATH, not the Gateway's, decides which launcher the agent would find. Resolve a bare command against that effective PATH, and use the Gateway's only when the agent does not override it.

Return a successful lookup as an absolute path: a relative PATH entry makes shutil.which yield a result relative to the Gateway's cwd, while the spawn runs with cwd set to the ACP workspace, where that path resolves elsewhere or not at all.

Regressions: a real-subprocess test with same-named launchers in the Gateway and agent PATHs (asserting which one ran), and a real-subprocess test whose PATH holds a relative directory while the ACP workspace is elsewhere. Both are red on the pre-fix code.

fix(groundroute): contain malformed web search and fetch payloads (#6603)
* fix(groundroute): contain malformed web search and fetch payloads

web_search and web_fetch assumed the GroundRoute 200 body was an object with
a `results` list of objects, and read it outside the request try/except. A
body that arrived as a bare list, as an object with a non-list `results`, or
with non-object entries raised AttributeError / KeyError out of the tool
boundary, so the tool call failed with a stack trace instead of the provider's
format error.

Validate the payload before normalizing it, following the containment rule
already applied to brave (#6550), serper, serply, sofya, tencent_wsa and
unbrowse: a non-object payload, a non-list `results` container, or a non-empty
list holding no objects returns the structured format error, non-object entries
in an otherwise valid list are skipped in order, and missing, null or empty
results keep returning "No results found".

* fix(groundroute): coerce non-string fetch fields

web_fetch sliced the fetched page's `content` (falling back to `snippet`)
to the snippet limit without checking its type, so a 200 body whose result
object held a number, boolean, or object there raised TypeError / KeyError
out of the tool boundary -- the same escape the previous commit closed for
the container shape. A null title also rendered as "# None".

Coerce non-string content to text before truncating, and render a missing
or non-string title as empty, matching the coercion sofya and unbrowse
already apply to their fetch fields.

* docs(groundroute): scope the falsy-title note to actual behavior

The guidance said a non-string title renders as empty, but the code only
empties falsy titles; a truthy non-string title still renders as its text
form via the f-string. Say "falsy" instead.

feat(authz): account disable/enable across every authentication surface (#4063 gap 3) (#6566)
* feat(authz): account disable/enable across every authentication surface (#4063 gap 3)

Vertical slice 1 of the user-lifecycle work: an operator can suspend an
account and every authentication surface rejects it, while the row —
credentials, role, OAuth linkage — is retained so re-enabling restores
exactly what was suspended.

- users.disabled (NOT NULL, server default 0) via migration
  0036_user_disabled; User/UserResponse carry and expose it.
- Enforcement at all four surfaces: password login (no credential
  comparison happens), JWT session resolution (401 ACCOUNT_DISABLED —
  sessions die at the next request), PAT resolution (the generic 401, no
  oracle), OAuth provisioning (403 with a contact-admin message; the
  link is kept so re-enable restores access).
- SQLiteUserRepository.set_disabled: single-column, serialized write
  (same idiom as update_system_role) with the last-ACTIVE-admin guard —
  disabled admins cannot authenticate, so they cannot restore management
  access; re-enabling is always allowed. Field-scoping completed both
  ways: the credential writer mirrors and never writes disabled, so
  a stale password-change snapshot cannot re-enable a suspended account.
- PATCH /api/v1/admin/users/{id} becomes a partial account update
  (system_role and/or disabled), each field routed to its field-scoped
  writer; empty bodies 422.

Tests 11->18: route (disable/re-enable, last-active-admin 409, empty
422, combined update), real-repo (field isolation both directions,
disabled-admin-not-active, guard inside the serialized write, re-enable
always), login rejection with the CORRECT password (only the disabled
gate can reject) plus resolver-visible flag. Mutations verified red:
guard removed (M19), login gate removed (M20 — after hardening the test
with a real hash so the gate is load-bearing).

* fix(authz): portable boolean default, alternate-authenticator suspension, active-admin role guard

Review round 1 on #6566 — three P1s:

- [PG default] sa.text("0") is a raw integer expression PostgreSQL
  rejects as a BOOLEAN default, breaking startup migration and fresh
  create_all bootstraps alike. Both the migration and the ORM model now
  use sa.false()/false() — dialect-rendered, portable.
- [alternate authenticators] WebSockets bypass AuthMiddleware, so a
  disabled user's still-valid cookie could open a NEW browser/stream
  connection and drive the retained session; the standalone LangGraph
  authenticate callback accepted the same suspended JWT. Both now route
  through a shared post-lookup validator (validate_resolved_session_user
  in deps.py — token_version + disabled in one place) that the HTTP
  dependency also uses, so a lifecycle change lands everywhere at once.
- [active-admin role guard] update_system_role counted every admin row,
  so 'disable B, then demote self' — or a combined {system_role, disabled}
  self-update — could strand the deployment with zero administrators able
  to authenticate or re-enable anyone. The demotion guard now counts
  ACTIVE admins only (disabled admins cannot authenticate), under the same
  serialization boundary.

Tests 18->22: shared-validator verdicts, WS admission after suspension
(real token, real repo), LangGraph-callback admission after suspension,
disable-then-demote-self + combined self-update both rejected (fake-repo
route level and real-repo update_system_role level). Mutations verified
red: helper's disabled check removed (M21 — three admission tests fail),
active-admin predicate reverted to all-admins (M22 — repo-level strand
scenario fails). 366 tests green on the affected surface.

* fix(migrations): chain 0036_user_disabled after upstream 0037

The maintainer main-merge brought 0037_project_document_summaries,
which branched from 0035 independently of this PR's 0036 — alembic now
sees two heads and every engine bootstrap fails. Chain 0036 after 0037
(single head; revision numbers are labels, the graph is what matters).

* fix(migrations): renumber user_disabled to 0038 and follow the chain-test convention

Upstream landed its own 0036 (run_idempotency_request) with 0037 chained
after it while this PR was in review — my 0036_user_disabled collided on
the number and my interim chain-fix (0036 revises 0037) left the graph
in a state upstream's chain tests reject (heads == [0037] hardcoded).

- 0036_user_disabled -> 0038_user_disabled, revises
  0037_project_document_summaries: single head 0038.
- Chain tests follow the repo convention (each migration PR appends the
  new head): 0032/0035 gain the DOC_SUMMARIES link and CURRENT_HEAD =
  0038; 0037's single-head assertion moves to CURRENT_HEAD with its
  own-revision link check unchanged.

* fix(migrations): pin the remaining chain tests to the 0038_user_disabled head

The 0027/0028, 0029 and 0034 chain tests still pinned the single head to
0037_project_document_summaries (and 0034 asserted the head's parent was
0036_run_idempotency_request), so the renumbered lifecycle migration broke
two unit-test shards. Follow the chain-test convention: every pinned head
moves to 0038_user_disabled and 0034 walks the chain through 0037.

* fix(authz): enforce account suspension on the internal-auth dispatch surface

Round-3 review finding: the internal-auth principal is synthesized from
trusted headers without a users-row lookup, so a suspended user with an
active channel binding kept driving the agent, and scheduler-owned runs
(their fabricated in-process requests skip AuthMiddleware entirely) kept
launching. Two gates now enforce the lifecycle there:

- AuthMiddleware rejects owner-bound internal calls whose users row is
  disabled (401 account_disabled) at the single gate every internal HTTP
  call passes through. Auth-disabled mode is exempt (no suspendable
  accounts, and its owner header carries the synthetic identity), and
  owner ids without a users row stay allowed — a nonexistent account
  cannot be suspended.
- start_run re-asserts it at run admission after the owner is resolved
  for attribution: the scheduler records the rejection as the
  occurrence's launch error and no run record is created.

Also addresses the remaining round-3 nits: drop the inline token_version
check duplicated by validate_resolved_session_user, correct the
local_provider comment (login never surfaces ACCOUNT_DISABLED), refresh
the stale 0038 docstring header, and restore the deps module caches in
the two suspension tests instead of leaking a closed engine.

* fix(auth): carry the disabled field on the frontend synthetic users

UserResponse now always includes disabled, so the auth-disabled contract
e2e (gateway /auth/me deep-equals the frontend synthetic user) failed
without the field on AUTH_DISABLED_USER. Add disabled to both synthetic
users and declare it optional on the zod schema — absent still parses as
not disabled for pre-gap-3 backends.

* fix(authz): log when the internal-owner suspension check is skipped

The middleware gate's users-lookup failure path silently degraded to
allow; keep the fail-open behavior but leave a WARNING with the
exception, so a store that cannot be read is observable in production
logs instead of invisible.

The Chinese command table skipped straight from /memory to /help, so the /agent list and /agent use <name> rows and the conversation-scoped agent-selection paragraph documented in README.md were missing entirely. Mirror them from the English README.

fix(scripts): bind local make dev and make start to loopback (#6587)
* fix(scripts): bind local make dev and make start to loopback

serve.sh and backend/Makefile started the Gateway with --host 0.0.0.0,
nginx.local.conf listened on every interface, and Next.js kept its
all-interfaces default outside Windows, so a local stack on a LAN or VPN
exposed ports 2026, 8001 and 3000, including /setup before the first
admin existed. The Docker stack and the README already document a
loopback-only default.

Bind the Gateway and frontend to 127.0.0.1 and keep nginx on loopback
unless BIND_HOST is set, the variable the Docker stack already honors.
nginx-local-conf.sh renders a copy listening on BIND_HOST, and serve.sh
resolves it before stopping anything so an invalid value cannot tear
down a running stack.

* docs(changelog): reference #6587

* docs(changelog): separate the loopback entry from the next bullet

fix(sandbox): frame remote search records on LF only (#6595)
* fix(sandbox): frame remote search records on LF only

BoxLite, OpenSandbox and Tenki sliced find/grep output with str.splitlines(),
which also ends a line at a bare carriage return, form feed, vertical tab,
file/group/record separator, next-line, and U+2028/U+2029. Every one of those
is legal inside a Linux filename and inside matched text, and the shared
parser already documents the opposite contract ("Split on \"\n\" only:
splitlines() would also split on characters that are legal in Linux
filenames").

Effects on these three providers, both silent:
- A path such as notes\x0bdraft.txt is reported as two unrelated paths, so
  glob() returns a path that does not exist (dropping the real one) and
  grep() reports the match against that wrong path.
- A matched line containing U+2028 -- which occurs inside real JavaScript and
  JSON string literals -- is truncated at that character.

Split on "\n" only, matching LocalSandbox, the AIO backend and E2B (#6573).

The colon half of #6573 is deliberately not included: it needs grep --null,
and these providers restrict their command to busybox-portable flags by
design. BusyBox grep rejects --null/-Z (it prints its usage line instead of
searching), so adding the flag here would break every grep on a BusyBox
image. Splitting the record from the right is not a substitute because
"path:12:needle: hello:world" is genuinely ambiguous without a NUL separator.

Tests: a cross-provider file pins the framing through each provider's own
transport seam (canned output, so it runs on any host) plus real-shell cases
for a separator-named file and separator-bearing matched text. 81 of them fail
on main and pass here; the provider suites are unchanged at 268 passed.
Verified with PYTHONUTF8=0.

Fixes #6594

* test(sandbox): make the real-shell fixtures POSIX-correct

Both real-shell tests were written against a Windows host, where _RS_POSIX
skips them, so neither had ever executed. On a POSIX host (macOS, and CI's
ubuntu/macOS runners, which do have sh/find/grep/head) both failed:

- The separator-named-file fixture emitted one octal escape per code point, so
  U+2028 became `\20050` -- printf reads that as a bare 0x80 byte plus the
  literal digits `50`, not U+2028. Dead `len(separator) == 1` branch removed;
  the code point is now emitted as one octal escape per UTF-8 byte
  (`\342\200\250`).
- The matched-text fixture used `printf '%s'`, which does not interpret
  backslash escapes, and interpolated a payload whose own double quotes closed
  the shell word; the file ended up as `const s = au2028b;\n` with no real
  U+2028. The escape now sits in printf's format string, with the octals
  assembled from the code point's UTF-8 bytes.

Verified by running the three cases directly on a POSIX-style root, which is
what the CI runners do: all three pass. The canned-output tests, which pin the
production change, are unchanged.

Also replaced the raw control characters in both changelog entries with
escape-style text (`notes\x0bdraft.txt`, `"a\u2028b"`, `"\n"`): a raw vertical
tab or U+2028 renders as nothing or a replacement glyph, and one code span had
a literal newline in it, which CommonMark collapses to a space and would have
read as `split on " " only`. Matches the #6520 entry's practice of naming the
characters.

fix(integrations): decode lark-cli and npm output as UTF-8 (#6590)
* fix(integrations): decode lark-cli and npm output as UTF-8

Every text-mode subprocess.run in lark_cli.py that captures lark-cli or npm
output omits encoding, so the bytes are decoded with the host locale. Both
write UTF-8 to a pipe: the @larksuite/cli npm package's bin is a Node wrapper
around a native binary that emits UTF-8 (lark-cli --help writes U+2014 as
E2 80 94), and npm output is UTF-8 too.

On a host whose ANSI code page is not UTF-8 (cp936, cp1252) the locale decode
silently mangles every non-ASCII field -- auth status --json returns a garbled
userName, so the status card shows mojibake -- and an undecodable byte raises
inside subprocess's reader thread, which is not re-raised: stdout comes back
as None or "", so a healthy CLI is reported as unavailable and a successful
run raises "lark-cli did not return JSON output."

Decode these captures as UTF-8, matching #5440 (PowerShell), #5904 (AIO
sandbox docker CLI) and #6548 (Git Bash output in LocalSandbox). The
whoami /user capture stays on the locale: whoami is a native tool that writes
the host code page, the same UTF-8/native split #6548 drew.

Tests drive the real functions with a stand-in CLI emitting UTF-8 CJK JSON
and pin the pre-fix decode path, so they fail on main and pass here on any
host locale.

Fixes #6589

* test(lark): isolate the paths singleton in the encoding suite

The new tests reached ensure_lark_cli_credential_tree through the global
get_paths() singleton, so every run created and hardened a real
<cwd>/.deer-flow/users/alice/integrations/lark-cli/{config,data} tree in
whatever directory pytest ran from -- the same runtime home a live deployment
keeps real per-user Lark credentials in. An autouse fixture now points the
singleton at tmp_path, matching what test_lark_cli_integration.py does.

Red/green is unchanged: reverting only lark_cli.py still fails the two
assertions that pin the decode, and the suite leaves no .deer-flow behind.

* test(lark): make the version probe pin the decode, drop the inert locale patch

Two test-rigor notes from review:

- test_probe_lark_cli_at_path only asserted available/error, and the probe
  returns available=True with any non-empty output and a zero exit code, so
  the test stayed green even with the encoding pin removed from
  _probe_lark_cli_at_path. The stand-in now answers --version with a non-ASCII
  payload and the test names the expected text, which fails on the unpinned
  call site (verified) and passes with the pin.
- The locale.getencoding patch was inert: the subprocess.run wrapper injects
  the codec for unpinned text-mode calls and lark_cli never consults the
  locale itself, so nothing reached the real locale-decode path. Dropped it,
  along with the now-unused import, rather than implying a redirection that
  does not happen.

The Windows shim forwards its arguments (%*) so the stand-in sees --version.

fix(release): reject a stale backend/uv.lock in the version gate (#6588)
* fix(release): reject a stale backend/uv.lock in the version gate

verify_versions.sh compared only Chart.yaml, pyproject.toml and
package.json, so bumping those three by hand passed the v* gate while
backend/uv.lock still recorded the previous root package version. The
backend image installs with uv sync --locked, so the chart and the other
images published while the backend image failed to build.

Run uv lock --check in backend/ as part of the gate, letting uv own the
PEP 440 normalization, and fail when uv is missing. The reusable
verify-versions workflow installs the uv version the backend image pins.

* docs(changelog): reference #6588

* fix(release): explain an unparsed lock version and stop blaming the lock for every uv failure

Print a fallback when the lock's root entry is not found, so the job log
does not show an empty field, and word the uv lock --check annotation so a
network error or uv crash is not reported as a stale lock.

fix(channels): share chat-to-thread bindings through the database (#6558)
* fix(channels): share chat-to-thread bindings through the database

ChannelManager kept its IM chat-to-thread bindings
(channel_name:chat_id[:topic_id] -> thread_id) in a per-process JSON file,
channels/store.json, loaded once and rewritten whole on every change. With
several Gateway processes a binding created on one replica was invisible to
the others (the next message for the same chat opened a second thread) and
concurrent writers clobbered each other's file.

- New channel_thread_bindings table (migration 0036_channel_thread_bindings)
  and harness package deerflow.persistence.channel_thread_bindings: key PK
  (the legacy composite string), channel_name, chat_id, nullable topic_id,
  thread_id, user_id, epoch created_at/updated_at; index (channel_name,
  chat_id). Dialect upsert keeps created_at; prefix remove and batched
  ON CONFLICT DO NOTHING import.
- app.channels.store.ChannelStore is an async protocol: SqlChannelStore for
  sqlite/postgres, JsonChannelStore (file I/O via asyncio.to_thread) for
  database.backend: memory. resolve_channel_store picks at ChannelService
  construction; ChannelService.start() imports an existing store.json once
  into an empty table and renames it store.json.migrated (a concurrently
  importing peer neither duplicates nor clobbers; a populated table leaves
  the file alone).
- Callers updated: manager, connection_identity.lookup_thread_id, Feishu
  (send() awaits the mapping writer; the synchronous lark callback bridges
  its two store calls to the Gateway loop with a bounded wait), Discord
  (channels_dir).
- Head pins in the 0027_0028/0029/0032/0034/0035 migration tests point at
  the new head; docs (channels and migrations AGENTS.md, CONFIGURATION.md,
  README) and CHANGELOG updated.

* docs(changelog): link the channel thread bindings entry to #6558

* fix(channels): reject only the Gateway loop in the Feishu store bridge

lark-oapi 1.5.5 invokes the message callback synchronously from its async
frame handler, on the private event loop that FeishuChannel._run_ws starts
for the SDK thread. The bridge's guard treated any running loop as unsafe,
so every real inbound message skipped the stored-topic lookup and the
pending-mapping restore: a reply whose parent card was mapped but whose
root was not fell back to the unknown root, and could consume an
unrelated pending clarification.

Only a wait issued from the Gateway loop itself (the loop that executes
the submitted coroutine) is refused now; the SDK's own loop may block for
the bounded wait, as that thread blocked on the JSON rewrite before.
Tests drive _on_message from a worker thread running its own loop, the
production shape, for both the lookup and the write path, and pin the
Gateway-loop refusal.

* fix(channels): defer unresolved Feishu lookups and harden the store.json import

Review follow-ups on the chat-to-thread binding store (#6558):

- Import: a legacy entry whose key, channel_name, chat_id, topic_id,
  thread_id or user_id exceeds its column width is skipped and counted
  with the malformed ones instead of failing the whole batch on
  PostgreSQL (SQLite silently accepted the same row, so the backends
  diverged on one file). The corrupt-file warning now says what each
  caller does: the JSON store starts fresh, the import is skipped and
  the file kept.
- Feishu bridge: store calls run on the Gateway loop under a 3s
  asyncio.wait_for (the SDK loop also services ws keepalives; the old
  10s bound could stall it per message), and the lark-thread wait is
  that budget plus 1s. A deadline or store error is StoreLookupUnresolved,
  never a miss: _on_message no longer routes such a reply onto its
  unknown root (which created a second thread and later overwrote the
  parent alias). The message joins a per-chat FIFO drained on the
  Gateway loop with backoff for up to 30s, then is dropped with a
  warning. _on_message is split into parse / resolve / dispatch so the
  deferred path dispatches the same way; later messages for the chat
  queue behind the deferred one.

* fix(tests): expect follow_redirects in the Jina client kwargs after #5808

#5808 made JinaClient pass follow_redirects=True to httpx.AsyncClient and
updated test_jina_client.py, but test_jina_response_limit.py and
test_jina_retry_after.py still pin the exact client kwargs to proxy and
trust_env, so every backend-unit-tests shard that lands on them fails on
main (the backend unit-test workflow only runs on pull requests, which is
why the push to main did not surface it). Update the two expectations to
include the new keyword.

(cherry picked from commit d5aa23156ce19ce36d95df03953442f83ae6d050)

* Revert "fix(tests): expect follow_redirects in the Jina client kwargs after #5808"

This reverts commit 5bee00bfb09c65a30f77fb4df47a1f82c47ecef7.

* fix(channels): bound deferred Feishu routing by the inbound queue capacity

Review follow-up on #6558: a store outage let every subsequent message for
a chat join the deferred queue with no capacity check (the bus reservation
was only taken after routing succeeded), and each queued message started a
fresh 30s retry budget when it reached the head, so a burst could be
retained for N x 30s and grow without bound.

- Intake is reserved BEFORE routing for every store-backed message
  (bus.reserve_inbound is thread-safe and already used from SDK threads),
  so deferred and live messages share the one configured bound,
  channels.inbound_queue_maxsize; a message that cannot be admitted is
  dropped at once with a warning, never queued or routed as a miss.
- The reservation travels with the message into dispatch (committed by
  _prepare_inbound), is released on the batch path (the flush reserves at
  publish time), on drop after the budget, on a failed deferral, on
  dispatch failure and for every leftover when the drain task is cancelled
  by stop().
- The retry budget runs from the message's arrival: a queued message whose
  budget is spent when it reaches the head is dropped without a lookup.
- The bounded resolver returns the unresolved outcome instead of raising
  it through the tracked task, which logged an ERROR for an expected,
  handled store timeout.
- Upstream's new blocking-io test constructs the store by its old class
  name; it now uses JsonChannelStore.

fix(mcp): reconcile committed Gateway config mutations (#6567)
* fix(mcp): reconcile committed Gateway config mutations

Install selective MCP binding fences inside the Gateway config commit boundary and finish teardown after releasing config locks. Reject frozen durable-task server changes before persistence.

Preserve drained cancellation semantics and cover delete/re-add, durable-only bindings, multi-server diffs, shared writers, and post-write reconciliation failure.

* test(mcp): pin committed handoff boundaries

Prove the fallback fence is installed before releasing the config lock, a committed writer cannot swallow an earlier shared reset, delete/re-add advances the applied baseline and cache generation, and retries after a post-write 500 have explicit conflict or missing semantics.

* fix(mcp): fence committed config after reload failure

Treat a post-write reload failure as a committed handoff failure so local MCP state is detached before releasing the config lock and teardown remains outside it.

* fix(mcp): always finish committed pool teardown

Run finish_mcp_reconciliation from a post-lock try/finally so response or logging failures cannot strand a retired full-reset pool.

* test(mcp): fence cold-start binding race

Pin the in-flight discovery path that keeps the committed fast path from admitting a late old-fingerprint binding.

* docs(mcp): document committed teardown guarantee

* fix(mcp): sanitize committed response errors

Keep post-write response conversion failures behind a fixed HTTP detail while preserving the retired-pool teardown guarantee.

* fix(mcp): avoid duplicate committed reconciliation error logs

fix(skills): record the content actually overwritten in custom-skill history (#6153)
* fix(skills): record the content actually overwritten in custom-skill history

Scope:
- backend/app/gateway/routers/skills.py: move the prev_content read of
  update_custom_skill and the current-content read of rollback_custom_skill
  into their drained persist tails (read -> write -> append_history in one
  worker thread, no awaits in between). The blocked-rollback branch now
  builds its informational entry separately. No behavior contract changes:
  status codes, cancellation draining, and prompt-cache refresh order are
  untouched.
- backend/tests/test_skills_custom_router.py: two regression tests that
  inject a concurrent write during the scan phase and assert the history
  entry's prev_content equals the revision actually overwritten on disk.

Why: prev_content was read before the security scans, so a concurrent
revision landing between that read and the persisted write was overwritten
on disk but absent from the history chain, making it unreachable by a later
rollback and desynchronizing the audit record.

Tests: uv run pytest tests/test_skills_custom_router.py --basetemp=... ->
36/36 passed (34 existing + 2 new); ruff check and ruff format --check clean
on both files. Python 3.12.13, Windows 11.

* fix(skills): serialize custom-skill mutations and pin the concurrency regression to the real window

- Add a module-level mutation lock shared by the edit, delete, and rollback
  paths, covering the full read -> write -> history-append sequence so a
  concurrent PUT cannot land between a request's predecessor read and its
  write (previously the projection lock started inside write_custom_skill,
  leaving that window open).
- Replace the two regression tests: they now pause the first mutation inside
  its storage write after the predecessor read (deterministic gate), complete
  a second real HTTP PUT inside that window, and assert the history chain
  stays replayable. Verified both tests fail against the base implementation
  (2 failed) and pass with the lock (2 passed); full file 36 passed,
  ruff check + format clean.

* fix(skills): scope the custom-skill mutation lock to the owning user

The lock serializing the read -> write -> append sequence was one process-wide
lock, and that sequence wraps write_custom_skill's entire user projection
rebuild. A user waiting on their own projection lock, or copying a large or
slow linked package, therefore stalled every other user's edit, rollback, and
delete of unrelated custom skills, even though their skill trees, histories,
and projection roots are disjoint. The base storage only serialized those
mutations per user projection.

Key the lock on the canonical owning-user storage root instead, so one user's
mutations remain a single critical section — including across separately
constructed storage objects, which a hot-reloaded config or a later request
creates — while two users never share it.

The read -> write -> append sequence still cannot interleave within a user, and
the lock is still acquired and released inside the worker thread's own with
block, so caller cancellation cannot strand it.

* fix(skills): serialize custom history across gateway processes

feat(channels): select the model per conversation via /model (#6534)
* feat(channels): select the model per conversation via /model

IM channels could list models with /models but had no way to choose one:
the model for a conversation came only from channel/session config or the
server default, so a user who needed a stronger or cheaper model for one
task had to reconfigure the whole channel or move to the web UI.

- /model <name> pins a model to the current conversation, validated
  against the caller-visible /api/models list (list membership doubles
  as the authorization check), persisted in thread metadata so it
  survives a Gateway restart and applies from the next message in
  place — unlike /agent use, which must start a new conversation.
- The pin is written to all three runtime carriers (run context,
  configurable, context) after the session layers merge, so it wins
  over channel/session configured models; like any explicitly
  requested model it also takes precedence over a Custom Agent's
  configured model.
- /model (no args) reports the effective model and its source through
  one resolver that mirrors the run merge order (default -> channel ->
  user, context carrier over configurable, both session-config
  carriers scanned); /model default clears the pin; /models names the
  pinned model in a footer.
- Pin lookups degrade instead of failing messages: the status query
  reports "Current model: unknown" on a lookup failure (matching the
  /models footer), and the reuse-thread preload leaves the in-process
  cache untouched so the next turn retries a transient threads.get.
- Reserve "model" in the slash-skill reserved-name contract (backend,
  contract fixture, frontend), register the Telegram handler, and
  document the command in /help, README, and README_zh.

* fix(channels): fence model pin cache and mirror runtime model resolution

Review follow-up for /model:

- Serialize cold pin loads with persist+cache publication under a
  per-manager lock, so a slow threads.get that captured pre-pin
  metadata can never overwrite a concurrently committed selection
  (commands are not run-serialized).
- _resolve_configured_model_name now replicates the run path's shallow
  session merges and applies the real runtime precedence —
  config.context (preserved by build_run_config, unbeatable by the
  setdefault-filled body context) > top-level context > configurable —
  instead of scanning per-layer carriers; a later layer replacing a
  nested carrier wholesale no longer leaks a stale value into the
  status reply.
- /api/models resolves the trusted bound owner for internal channel
  calls and filters the list with the owner's role, so /model
  selection gates on the same principal that run admission admits for
  that account.

Tests: pin-write-vs-in-flight-load race, status compared against the
real merged runtime config (parametrized across carriers),
nested-carrier replacement, and owner-role filtering with the real
RBAC provider; each verified red by reverting exactly its guard.

* fix(channels): share model resolvers with the run path and harden the pin lifecycle

The /model status reply re-implemented the session-layer merge and the
Gateway carrier precedence, and it ignored the custom-agent model
fallback — on a thread pinned to a custom agent whose config sets
``model:`` it reported "server default" while the run actually used
the agent's model. Review also found the pin lock spanned a network
call and a stale pin bricked its conversation behind the generic
error fallback.

- Extract ``_select_carried_model_name`` as the single carrier-precedence
  rule; the status reply reuses the run path's exact ``_merge_dicts``
  layer shapes, so a future layering change has one place to touch.
- Extract ``_resolve_message_assistant_id`` / ``_resolve_assistant_id``
  and share the assistant precedence chain between the run path and
  the status reply.
- Fall back to the resolved custom agent's configured ``model`` when no
  session layer carries one, mirroring the agent factory's
  ``_resolve_model_name(requested or agent_model_name)``; the reply now
  distinguishes "(from channel configuration)" and "(from agent
  configuration)".
- Run the cold ``threads.get`` in ``_load_thread_model`` outside
  ``_model_pin_lock``; only cache publication takes the lock, with a
  post-GET re-check so an in-flight /model write still wins over the
  older snapshot.
- Detect the run-admission allowlist rejection in ``_handle_message``
  and recover: clear the stale pin (durable write plus cache under the
  lock) and reply with the reset and the /model recovery instead of
  the generic internal-error fallback.
- Document /model and the ``channel_model_name`` pin semantics in
  backend/app/channels/AGENTS.md.

* fix(channels): fence stale-pin recovery and cover streaming admission failures

Review round 4 found the stale-pin recovery itself unsafe and
incomplete:

- Recovery cleared whatever pin was current when the delayed
  admission rejection arrived, so a rejection for an old pin could
  erase a replacement selection committed mid-flight (and tell the
  user the new model was unavailable). ``_stale_pin_recovery`` now
  takes the failed run's own selection (``expected_pin``, read from
  its run context) and clears only while that selection is still
  current under the lock; a replaced or already-reset selection gets
  a non-destructive reply instead.
- Feishu/Telegram/DingTalk streaming turns never reached the recovery
  hook because ``_handle_streaming_chat`` swallows start_run's 400
  into its terminal-error reply. The recovery now runs in the
  streaming terminal-error path too, delivered as the single final
  outbound with the same dedupe cleanup; blocking, streaming, and
  fire-and-forget run-creation paths all handle the rejection at the
  site that knows the submitted selection.

* docs(channels): fit the /model entry within the agent-guidance size budget

The base file sits one byte under the AGENTS.md hard limit, so
documenting /model requires net-zero growth: keep the command-inventory
addition and a compact pin-semantics sentence, and losslessly tighten
the surrounding prose (the file was already at the limit).

* fix(channels): apply the review suggestions on /model replies

Three non-blocking findings from the latest review:

- The /models pin footer decorated the failure string too, advertising a
  pin next to an error that lists nothing. The command now fetches the
  listing through ``_fetch_gateway_json`` and appends the footer only on
  a successful fetch.
- The /model status reply labeled every session-layer model "from
  channel configuration", misreporting user- and default-layer models.
  The label is now "session configuration" for every session layer.
- Stale-pin recovery replies read as if the turn went through, but the
  run was rejected before starting and the triggering message never

  "Your message was not processed — please send it again."

* fix(channels): recover stale model pins on the follow-up drain path

The drain is the fourth run-creation path and the only one without
stale-pin recovery: a /model pin that left the allowlist while follow-ups
were buffered made every drained runs.create fail admission, requeueing
the batch into the same 400 on every cycle with no user-facing recovery —
contradicting the documented "stale pins self-clear" invariant.

- Compute expected_pin from the drain's run context (mirroring
  _handle_chat_on_thread, initialized None since _resolve_run_params is
  itself inside the guarded try) and run _stale_pin_recovery on drain
  failure before requeueing; the pin self-clears and the requeued batch
  succeeds on the next cycle.
- Pass the caller-authoritative thread_id into _stale_pin_recovery:
  every call site already holds it, so recovery never re-derives it from
  the message — a store-mapping rewrite between dispatch and recovery
  can never clear the wrong conversation's pin, and the lookup's
  failure mode (and its guard) disappears entirely.
- Return StalePinRecovery(text, resolved) so requeueing callers can
  tell a cleared pin from a repeat failure: the drain logs INFO when
  the next cycle is free of this rejection and WARNING when recovery
  could not remove it (persist failed, or the selection came from
  session configuration, which still carries it) — no silent infinite
  requeue loop. Drain logs carry structured facts only: the reply text
  ends with a "please resend" note that would double-process buffered
  messages retried automatically (GitHub, the only buffering channel,
  sends log-only anyway).
- Reword the config-carried recovery reply: with no pin held, the
  rejected selection came from session configuration — name that source
  and the fix instead of claiming a default takeover that would not
  happen.
- Correct the _load_thread_model lock docstring (writes deliberately
  hold _model_pin_lock across threads.update) and read the agent config
  for /model status off the event loop via asyncio.to_thread, with a
  Blockbuster-gated blocking_io regression test.
- Pin the under-lock re-check in _stale_pin_recovery with a concurrency
  test (a /model committed during the lock-wait window wins; recovery
  persists nothing), mutation-verified — the drain is the only caller
  running on a background task without the serialized-run lock, so it is
  the path most exposed to that window.

* fix(channels): apply the third review round on /model command replies

- Delete the dead kind == "models" branch in _fetch_gateway: /models has
  rendered the listing inline since the pin-footer fix, so the helper's
  copy was unreachable and had already diverged (unguarded m["name"], no
  pin footer). The internal-auth-header test now drives the surviving
  /memory kind.
- Guard the inline /models listing comprehension like the
  _handle_model_command sibling (isinstance(m, Mapping) and
  isinstance(m.get("name"), str)), so a malformed payload entry can no
  longer turn the command into the generic internal-error reply;
  regression: test_models_command_skips_malformed_entries.
- Drop the unused user parameter from _resolve_bound_owner_for_model_list:
  the resolved owner comes solely from the trusted header, and the
  parameter implied the caller's own principal shaped the filter.

* fix(channels): apply the fourth review round on the /model lifecycle

- Preserve fresh model pins across cache eviction: a cold threads.get
  racing a successful /model write could still publish its stale
  snapshot after clear-on-pressure evicted the fresh entry — the
  in-cache re-check cannot see an eviction. The model-pin cache now
  carries a write generation; a load whose generation moved during the
  GET refetches once instead of publishing over the committed
  selection. Regression:
  test_fresh_model_pin_survives_cache_eviction_during_cold_load
  (blocked GET, write, eviction, then the refetch wins),
  mutation-verified.
- Resolve context-carried agents before reporting their model: /model
  status now mirrors the run path's effective-agent rule — explicit
  message/thread choice overwrites every carrier, then the merged
  carriers' agent_name (new _select_carried_agent_name, sharing the
  model-name precedence via _select_carried_value), then the
  session-layer assistant_id that only setdefaults into context. A
  session with context.agent_name=coder now reports coder-model instead
  of server default, and assistant_id=writer alongside
  context.agent_name=coder reports coder-model instead of writer-model.
  Regressions: context-carried, context-beats-assistant_id, and
  thread-pin-beats-context status tests.

fix(skills): confine review_skill_package local targets to the caller (#6580)
* fix(skills): confine review_skill_package local targets to the caller

Local path targets were allowed anywhere under the Gateway cwd or /tmp.
Every documented deployment keeps DEER_FLOW_HOME under the cwd, so a user
who knew another user's id could pass
.deer-flow/users/<id>/skills/custom/<skill> and get that skill's SKILL.md
and references/ back in the model response. The tool is always available,
so skill tool policy could not remove it.

Local targets are now confined to the configured skills root and the
caller's own user directory (resolved from the runtime user id through
make_safe_user_id, like the user-scoped skill storage). skill:// and
inline:// targets are unchanged.

* test(skills): pin dot-dot and sandbox-planted symlink review targets

* docs(changelog): reference #6580

* fix(skills): ignore a review skills root that contains per-user directories

A skills root configured at or above DEER_FLOW_HOME would re-admit every
user's directory as a local review target. Drop such a root and log a
warning instead of trusting it silently.

* test(skills): use the platform temp dir for the shared-temp review case

A hardcoded /tmp does not exist on Windows dev hosts.

docs: list the summarize event tag and scope the extension example's claims (#6582)
* docs: list the summarize event tag and scope the extension example's claims

RUN_EVENT_STREAM.md listed seven middleware tags, but the catalog and the
run event stream contract carry eight; `summarize` is emitted by
SummarizationMiddleware for every successful summary result. Add the tag,
describe the event, and pin the documented list to MIDDLEWARE_EVENT_TAGS so
the next tag cannot drift silently. summarization.md now lists all eight
`changes` fields of that event.

The extension example said it showed all five (README, pyproject, module
docstrings, test name) or every contribution kind, while ExtensionRegistry
has eight. Say it demonstrates five, name the three it does not, point to
the observers guide and the bookmarks plugin, and assert in the example's
test that the two observer kinds stay unregistered.

fix(sandbox): attest lark broker mode per Pod and quarantine uncertain shell outcomes (#6436)
* fix(sandbox): attest lark broker mode per Pod and quarantine uncertain shell outcomes

Why this change:
Two fail-open paths in the AIO sandbox lifecycle. First, the lark broker
capability probe collapsed "provisioner unreachable" into "broker not
configured": one 1.5s timeout cached a negative for 300s, so new sandboxes
were created without the broker sidecar while the per-user credential
directories were still bind-mounted into the container, and existing Pods
kept being reused without their actual mode ever being read. Second, an
implicit-shell command that timed out or returned an unknown status only
marked the current client object; warm-pool reclaim and rediscovery built a
fresh client that re-entered a container whose shell state could not be
proven clean, and nothing about that ambiguity survived a Gateway restart.

What changed:
- The capability cache stores confirmed observations only, keyed per
  provisioner endpoint/auth identity; an unknown answer (timeout, malformed
  payload) raises instead of selecting credential placement, while a
  confirmed broker requirement is retained through outages. One in-flight
  probe per identity shares success and failure, and a Pod-attested mode
  contradicting the cache forces one shared refresh.
- Execution uses the mode attested for the actual sandbox:
  SandboxInfo.lark_cli_broker flows from the provisioner's atomic Pod
  observation into the client, so a probe outage delays drift detection but
  never denies reuse of an attested runtime, and never trusts an unattested
  one.
- The provisioner reports each Pod's actual broker mode, generation (Pod
  UID) and shell capacity from one read, rejects lark requests conflicting
  with its configuration (409/503 carrying a capability-refresh marker the
  Gateway uses to drop the stale cache entry), rejects conflicting or
  Terminating Pods on coordination creates while reporting Terminating as
  data to status/get/list, and answers Pod presence independently of
  Service readiness.
- A persistent quarantine (DEER_FLOW_HOME/sandbox-quarantine, keyed by
  scope/sandbox/generation) fences containers after uncertain implicit
  shell outcomes across client rebuilds and restarts; in-process reuse,
  warm reclaim, discovery, create responses and orphan reconciliation all
  pass one policy gate, and replacement runs under the existing ownership
  and teardown fences. A fenced sandbox still tracked after a failed
  release-recycle is destroyed inline on the next acquire.
- Quarantine records retire only after confirmed absence, retrying partial
  cleanup for the quarantined generation and releasing remembered ports
  under the same fences; local stop failures now propagate instead of being
  logged away, and remote destroy errors surface to callers.

Problem solved:
A provisioner blip could silently strip broker isolation from new lark
sandboxes for minutes at a time, and ambiguous shell outcomes let corrupted
default shells persist across warm reuse, rediscovery and restarts. Docs
updated: README, aio_sandbox and skills AGENTS.md.

* docs(changelog): record sandbox attestation and quarantine fix (#6436)

* fix(sandbox): preserve active leases and fail closed on unattested broker modes

Concurrent uploads could recycle a healthy AIO runtime while another holder
was creating or cleaning up a command session. Older provisioner responses
could also trigger destructive replacement before failing admission.

- Distinguish pending session creation from ambiguous outcomes and reserve
  idle teardown until execution and upload holders finish scope cleanup.
- Reject stale fork lookups and reconcile cancelled acquires without
  releasing a sandbox still borrowed by another holder.
- Default Lark broker mode to unverified and preserve unattested Pods until
  the provisioner is upgraded.
- Recognize Docker 29 absence diagnostics while matching resource names exactly.
- Preserve Gateway upload errors and cover admission and lifecycle regressions.

* fix(sandbox): scope the unverified-broker refuse path to attested providers

The fail-closed raise in _lark_cli_env_from_runtime treated every Sandbox
without a lark_cli_broker attribute as unverified, but only AioSandbox
carries the attestation — E2B, OpenSandbox, Tenki, and Boxlite have no
broker sidecar, no credential mounts, and no provisioner to upgrade, so
every lark-cli command on those providers failed with an unactionable
error.

Declare the tri-state on the Sandbox base class (defaulting to False,
the only mode brokerless providers have) so the None fail-closed path
stays scoped to AioSandbox's deliberate unverified default.

- Add lark_cli_broker: bool | None = False to the Sandbox ABC, mirroring
  the persistent_shell_sessions tri-state pattern
- Add a regression test pinning the non-broker overlay for a provider
  without the attribute

* fix(sandbox): close review gaps in broker attestation and teardown lifecycle

Address the latest #6436 review round:

- The provisioner's post-build broker-mode 409 now carries the
  capability-refresh marker, so an incompatible-mode conflict surfaced by
  idempotent re-create, attestation drift or post-create verification drops
  the Gateway's cached capability observation instead of repeating the same
  409 for the full negative-cache TTL.
- AioSandboxProvider.destroy() returns the _destroy_tracked outcome: False
  when teardown is deferred because an execution/upload holder or a peer
  teardown is still active, so callers can no longer mistake a deferred
  destroy for a completed one.
- A live replacement under the same logical ID proves the fenced old
  generations are absent; retire_replaced_generations prunes only those
  stale records so they cannot strand future creates, while the live
  generation's fence and unversioned crash fences are never touched.
- SandboxInfo.from_dict keeps a missing lark_cli_broker attestation
  unverified (None) instead of silently rehydrating as attested non-broker.
- The restricted-network inspect path shares the strict
  _is_no_such_network_error parser, closing the substring loophole for
  context-name collisions and wrong-target errors.

* docs(sandbox): condense lease notes to keep the AGENTS.md chain under the size gate

The three lease notes added in 26c307f3 pushed the effective guidance chain
to 98,312 bytes — 8 over the 98,304 hard limit enforced by agent-guidance
(AG002). Fold them into two lines carrying the same rules.

fix(sandbox): number remote read_file line ranges like LocalSandbox (#6585)
* fix(sandbox): number remote read_file line ranges like LocalSandbox

E2B, BoxLite, Tenki and OpenSandbox sliced ranged reads with str.splitlines(), which also ends lines at a bare "\r", \f, \v, \x1c-\x1e, \x85, \u2028 and \u2029. LocalSandbox.read_file, count_file_lines and the read_file truncation marker end lines only at "\n", so on those providers a ranged read of such a file returned different lines, and following a truncation marker's start_line went back into text already shown. Add split_file_lines next to count_file_lines and use it in the four providers.

feat(projects): best-effort LLM summaries for shelf documents (#6581)
Opt-in per-document summary column rendered into the injected
<documents> index, list_project_documents JSON, and the documents API.

Pipeline (projects/summaries.py, behind the narrow enqueue_summary
interface):
- The two shelf write routes enqueue a job on created=True; dedup hits
  never regenerate. Off by default (projects.summaries_enabled).
- Bounded worker pool (summary_concurrency + bounded summary_queue_size;
  a full queue drops the job) fed by FIFO; shutdown drains queued jobs,
  delivers one sentinel per worker via blocking put (queue smaller than
  the worker pool cannot strand idle workers), and bounds only
  genuinely in-flight jobs with the grace period.
- Jobs carry (document_id, project_id, user_id) explicitly; the job's
  owner is bound into the user ContextVar around the model call so
  tracing/usage attribution never falls back to 'default'.
- Text source reuses read_text_serving_path (convertible-first rule,
  content validation); conversion has no deadline (await_drained), the
  model call has a caller-side wait limit — the worker slot is retained
  until the provider call actually finishes and late results are
  discarded.
- Output contract: strip leading <think> reasoning -> unwrap fence/
  quotes -> collapse to one line -> empty is NULL -> UTF-8 byte cap on
  a character boundary; length-capped responses (provider-normalized
  detectors) are failures.
- set_summary pins updated_at (literal self-assignment) so a landing
  summary never reorders the shelf; owner-predicated UPDATE is a no-op
  on rows purged mid-generation.
- Metrics: eligible/success/failed/skipped/queue_dropped/
  uncapped_accepted.

Schema/config:
- project_documents.summary (migration 0036, nullable, no backfill;
  forward-compat floor unchanged).
- Six projects.summary_* keys, all registered in STARTUP_ONLY_FIELDS
  (captured once at lifespan startup); config_version 57 -> 58.
- run_oneshot_llm gains an optional model_overrides passthrough (passed
  only when set, existing callers unchanged) and a detailed variant
  exposing the raw response message for termination-signal detection.

Docs: API.md response field, ARCHITECTURE.md pipeline paragraph,
migrations AGENTS.md chain head, root AGENTS.md records the scoped
all-core exception with the lift-out path.
