* fix(crawl4ai): construct the fetch client off the event loop
Crawl4AiClient builds an httpx.AsyncClient per fetch, and AsyncClient
construction loads the TLS trust store synchronously: on the agent event
loop that blocks every other request for the CA bundle read. Construct it
through asyncio.to_thread, the same rule the RAGFlow/LightRAG and
You.com/GroundRoute/Webz clients already follow; the request and cleanup
stay on the loop.
* docs(agents): list Crawl4AI among the off-loop HTTPX clients
#7889 extended the same sentence for its providers; keep the named list in
the same change set as the client, and record the clients that still
construct on the loop so the next migration has a checklist.
Context compaction runs from abefore_model/aafter_model on the shared loop,
and its async candidate loop constructed the summary provider inline.
create_chat_model can read local CLI credentials while it is constructed
(Codex auth.json, Claude Code credential files), so an automatic compaction
stalled every other request for that read.
Split construction out of _model_for and add _amodel_for, which builds the
provider on the assembly pool; the sync path keeps building inline. Anchor
and failure-cache semantics are unchanged, so a broken candidate still falls
through to the next one, and inference still awaits on the loop.

Thread title generation runs inside the agent graph (aafter_model), and it
built its configured model inline. create_chat_model can read local CLI
credentials while it is constructed (Codex auth.json, Claude Code credential
files), so the first turn of every new thread read them on the shared loop
and other requests waited for it.
Build the provider through run_assembly, the dedicated assembly pool the
one-shot helpers, skill moderation, the goal evaluator and start_run already
use. Inference still awaits on the loop, and the sync path is unchanged.
A Blockbuster regression builds the real Codex provider: on main the gate
rejects the credential read, the broad fallback swallows it, and the local
fallback title replaces the model's title; with the change the provider is
constructed on a worker thread and the model's title is kept.
* fix(channels): deliver the DingTalk reply when an AI card request fails
dingtalk-stream's AICardReplier logs a failed card request and returns
as if it succeeded; its create call returns the card ID it generated
before the request. The channel stored that ID, so neither the running
reply's text fallback nor send()'s sampleMarkdown fallback could run,
every streamed update failed silently, and the final answer never
reached DingTalk.
Send createAndDeliver and the streaming update through the channel's
httpx client with its token, using the bodies the SDK sends, and raise
on HTTP and transport failures so both fallbacks run. The SDK replier,
its per-card map and the token shim it needed are removed.

scan_skill_content and the goal evaluator built their chat model inline on
the Gateway event loop. When the provider reads local credential files (the
Codex provider reads the Codex CLI auth.json while it is constructed), each
scanned skill edit, rollback, install or agent-managed skill write, and the
evaluator construction in each goal run, did synchronous file IO on the
shared loop, so other requests and streams waited for it. #7484 removed the
same stall for the one-shot helpers and listed these two constructors in the
utils guidance as not covered.
Build both providers through run_assembly, as the one-shot helpers do: the
moderation model in scan_skill_content, the evaluator in
evaluate_goal_completion when no model is injected, and the run worker's
cached evaluator factory. A scan without app_config (the in-graph
skill_manage call) also reads the live config in that pool, and its
fail-closed fallback reuses that config instead of reading config.yaml again
on the loop; an unreadable config still fails closed. Verdicts, the
fail-open/fail-closed policy, error propagation and tracing are unchanged,
and cancellation during construction never starts inference.
tests/blocking_io/test_system_model_offloop.py builds a real CodexChatModel
under the strict Blockbuster gate. On main the scan fell back to its
fail-closed "unavailable" block, the evaluator raised BlockingError
(os.stat), and the worker stood the goal down as evaluator_failed.
send_file short-circuited with `return True` for non-final messages, which
reported a successful upload that never happened. Per the Channel.send_file
contract ("Returns True if the upload succeeded, False otherwise"), a
message with no upload path must report False so the attachment lands in the
'failed' feedback the user relies on, instead of being silently dropped.
Drop the non-final short-circuit so the method reaches its normal
connectivity checks (no WS client / no thread frame -> False), matching every
other channel.

* fix(gateway): read the live config off the loop for thread token usage
build_context_usage resolves the model capacity through deps.get_config,

each /threads/{id}/token-usage request paid that file IO on the shared
Gateway loop.

* fix(channels): give DingTalk AI cards the channel token, not the SDK fetch
AICardReplier's async card calls read dingtalk_client.get_access_token()
inline, and dingtalk-stream refreshes it with requests.post and no
timeout. Card creation and card streaming both run on the Gateway loop,
so the first card and every SDK refresh after it (about every two hours)
blocked the loop for the whole token request, without bound if DingTalk
stalled.
Hand the replier a _CardTokenClient that serves the channel's own
httpx token (10s timeout), set before card creation and before every
streamed update. A token failure while streaming now raises into send's
existing sampleMarkdown fallback instead of being skipped silently.
Pin it with a strict blocking-I/O anchor over a real DingTalkStreamClient
and AICardReplier, a gate meta-check, and unit tests for token rotation
and failure. LocalHttpServer also records each request's method, path
and headers.

* fix(channels): resolve reply artifacts off the event loop
_handle_chat_on_thread and _handle_streaming_chat called
_prepare_artifact_delivery inline. For every presented file it resolves
the virtual path (realpath), resolves the outputs root, and checks the
file with is_file and stat, all on the Gateway loop that also serves
every other channel and request.
Run it through asyncio.to_thread on both reply paths, and anchor both
through the real manager under the strict blocking-I/O gate.

* fix(community): resolve async tool config off the event loop
Agent runs execute on the Gateway event loop, and the async community
tools resolved their tool config through get_app_config() inline. That
call stats and hashes config.yaml and extensions_config.json on every
call and reparses them after an edit, so each tool call held the loop
for it, up to three times per call: Tavily, SearXNG and Firecrawl read
the config again to build their client, InfoQuest read it three times,
and the browser tools read the launch config for every action.
Resolve it through asyncio.to_thread once per call, as image_search and
groundroute already do, and build the client from that same read. This
covers jina_ai, crawl4ai, browserless, tavily, searxng, firecrawl,
infoquest, ragflow, lightrag and browser_automation.

* fix(community): resolve the jsonify dataset_rows config off the event loop
dataset_rows_tool is async and called _load_settings() inline, so every
call ran get_app_config()'s stat + sha256 revalidation on the loop.
Read it through asyncio.to_thread like the other async community tools,
and add the tool to the off-loop anchors.

* fix(auth): read the live config off the event loop on public auth routes
/register, /setup-status, /providers, /oauth/{provider} and
/callback/{provider} read the live auth config through get_app_config()
inline. That call stats and hashes config.yaml and extensions_config.json
on every request and reparses them after an edit, and these routes are
unauthenticated, so any client could keep that file IO on the event
loop. /login/local already reads its throttle policy in a worker.
Read the registration gate through asyncio.to_thread, and the SSO
routes' auth.oidc section through a shared _oidc_config() helper that
does the same.

* fix(gateway): read the route authorization config off the event loop
AuthMiddleware resolves route permissions for every authenticated
request, and resolve_route_permissions read the hot-reloaded
authorization config inline. get_app_config() stats and hashes
config.yaml and extensions_config.json on every call and reparses them
after an edit, so that file IO ran on the event loop per request.
Read it through asyncio.to_thread, like the plugin authorization path
already does. The context copy keeps runtime config overrides visible.
* docs(changelog): reference #7557 for the off-loop route authorization config read
* docs(config): note the get_app_config read cost where it is documented
Move the off-loop note from gateway/AGENTS.md, which is 12 bytes under
its hard limit, to the Config Caching section that documents what each
get_app_config() read costs.
* fix(utils): construct one-shot models off the event loop
* docs(utils): document all one-shot callers and offload scope
Project-file summaries use the shared one-shot helper as well as input
polishing and follow-up suggestions. Include that third caller in the
README and utility guidance, and distinguish the separate skill scanner
and goal evaluator constructors.
Runtime and tests are unchanged. The existing exact-head strict and caller
regressions pass together: 80 passed on Windows with Python 3.12.14.
* fix(memory): flush pre-compaction memory off the event loop
The async compaction path fired the before-summarization hooks inline.
memory_flush_hook hands the summarized messages to add_nowait, which is
sync HTTP for mem0 and Honcho (inherited default -> add) and OpenViking
(its own override), so every automatic compaction with an HTTP memory
backend blocked the Gateway event loop for the whole request.
acompact_state now runs the hooks through asyncio.to_thread, as
MemoryMiddleware.aafter_agent already does for its writes. Ordering,
failure isolation, summary-first timing and context propagation are
unchanged; the sync compact_state path is untouched.

* fix(sandbox): derive the AIO sandbox ID off the event loop in async acquire
_acquire_internal_async offloads every acquire layer except the sandbox ID
derivation, which ran inline. _sandbox_id_for_thread checks the thread's
skills_view directory with exists(), and resolving it goes through
Paths.base_dir, so each async thread acquire made filesystem syscalls on the
event loop. The strict blocking-I/O gate raises on it.
Run the derivation through the same owned-worker helper as the reuse and
warm-pool layers around it, and anchor it in the blocking-I/O suite for both
the default and the policy-scoped ID.

* fix(projects): make read_file_chunks cancellation-safe for worker handoffs
Cancelling a project document read had three unsafe windows around the
dedicated file-I/O worker: (1) a cancellation landing between the open
worker completing and the result reaching the coroutine leaked the
handle (the cleanup path never saw it); (2) the cleanup close could
start while an admitted read was still running; (3) a repeated
cancellation let the caller escape before the close worker settled
(#7491).
Gate every admitted operation with the existing await_drained
primitive: cancellation is delivered only after the operation settles,
the open result is retained in a list cell the moment the worker
returns it (so the cleanup close always has the handle), and waiting
for the next chunk via the yield stays immediately cancellable.
Regression tests gate the real executor with asyncio events at the
worker boundary (real files, no mocks): all three windows are red on
unmodified main and green with the fix; the happy path is unchanged.
The dispatch-spy promotion tests that import app.gateway.routers need
the full backend dependency set and could not run in the minimal local
env; they fail identically on unmodified main (verified).

* feat(projects): search shelf documents by keyword
Add search_project_documents: two-tier name/summary then bounded content scan, case-insensitive substring matching with original-text offsets. Never converts on the fly; reports stop_reason, content_scanned, skipped reasons, and capped unscanned/truncated ids.
* fix(projects): derive unscanned count without paging after budget trip
Review feedback: once the content budget trips, stop paging list_active to enumerate unscanned ids — cap ids at the trip page and derive the honest total from one count_active query (tier 1 is exhaustive, so active - tier1 hits - processed = unscanned). Also add a tool-level isolation test pinning that search never crosses projects or users.
* fix(projects): scan the shelf over one stable snapshot, not offset pages
Review feedback: offset paging re-read the live shelf per page, so a concurrent upload/trash between pages could duplicate a match or silently skip one while still claiming complete coverage. Tier 1 now materializes the whole shelf in a single SELECT (one read snapshot) and tier 2 iterates those same rows; the budget-trip unscanned count is derived exactly from the snapshot with no extra query. Mid-scan upload/trash regression tests pin both failure modes.
Unsafe filenames and unnamed parts were dropped silently: the response kept
`success: true` with an empty `files` list, so the #7122 frontend gate never
blocked a chat send whose attachment had been rejected (#7160).
Both drop arms now record the rejected name in `skipped_files`, and `success`
follows `bool(uploaded_files)`: an all-rejected batch fails, a mixed batch
succeeds and lists what was dropped.
* fix(acp): fail fast when an ACP agent exits and drain its stderr
An ACP agent that exited before answering (missing credentials, a wrong
argument) left invoke_acp_agent waiting for the whole timeout_seconds
budget (30 minutes by default) and then suggested raising the timeout.
The pinned SDK never fails pending requests when the agent's stdout
reaches EOF, so nothing noticed the process was gone.
The SDK also opens the agent's stderr as a pipe and never reads it. An
agent that logged more than asyncio's pipe buffering absorbs blocked on
its next stderr write and stalled the invocation the same way.
Race the ACP exchange against the agent process: when it exits (or a
newer SDK reports the connection closed), allow a short grace for
responses still buffered in the pipe, then report the exit code. Drain
stderr continuously into a bounded tail that is logged on failure and
kept out of model-visible text.
* fix(acp): log the full stderr tail on timeout and pin tail retention
Log the timeout tail after the SDK context has terminated and reaped the
agent, so lines still in flight when it stalled are included. Make the
exit test write more stderr than the retained tail, so keeping the start
of the stream instead of its end fails the assertion on the fatal line.
* feat(community): migrate You.com tools to async HTTP
The You.com provider sent its search request through a sync httpx.Client. A
sync LangChain tool invoked through ainvoke runs on the default executor, so
the request held one of that pool's threads for the whole network round-trip,
and several providers queried in parallel queued behind each other.
Make the tool a coroutine over httpx.AsyncClient, resolve the API key and
the configured max_results in a single config read, and move both disk reads
off the event loop: the tool config, and the User-Agent, which reads the
installed package metadata the first time it is needed.
* refactor(community): drop the dead You.com API key wrapper
The async migration resolved the key and max_results through
_resolve_tool_settings, which left _get_api_key with no production
caller: only TestGetApiKey still exercised it. Keeping a second seam
around the same config read lets it drift from the real call path, so
drop the wrapper and point the tests at _resolve_tool_settings.
Also keep the hot path off the executor: _user_agent is cached, so only
the first call reads the installed package metadata. Later calls are
in-memory hits and now skip the to_thread round-trip.
Finally, record which httpx client factory the provider reaches for in
the runtime anchor. MockTransport runs its handler on the calling thread
without real blocking I/O, so a provider that stayed async but sent the
request through a sync client would satisfy the thread assertion; the
recorded factory is what catches that partial regression.
* test(community): align You.com URL safety stub with async tool
The URL safety matrix still patched the removed _get_api_key seam and invoked the You.com tool synchronously. Mock the awaited search with AsyncMock and call the tool through ainvoke so URL screening remains covered after the async migration.

* fix(mcp): keep rotating OAuth refresh tokens across restarts and Gateway instances
MCP servers on the OAuth refresh_token grant lost their rotated refresh
token whenever a new process or manager started (restart, tool-cache
reset for non-task servers, every personal-connection run, a second
Gateway instance) and re-seeded with the consumed configured token,
getting invalid_grant for good.
- New table mcp_oauth_tokens (migration 0047_mcp_oauth_tokens), one row
per refresh_token connection keyed (scope, owner_user_id, server_key):
('deployment', '', name) or ('personal', owner, personal runtime
name). Access and refresh tokens are DEER_FLOW_CREDENTIALS_KEY
ciphertext; a config fingerprint (token_url, client_id, grant, scope,
audience, seed) makes a changed seed win.
- OAuthTokenManager re-reads the row under its process lock, adopts a
peer's valid token, and otherwise claims the refresh with a lease plus
a version compare-and-set (database clock), fetches outside any
transaction, writes under the lease and releases it on failure.
- The Gateway installs the store (sync engine via to_thread) around the
LangGraph runtime for sqlite/postgres; personal managers pass their
owner. client_credentials stays in process; an unloadable key falls
back to process memory; database errors fail the refresh.
- credentials_key_consumers lists refresh_token MCP OAuth servers, so a
declared multi-instance deployment needs the shared key.
Docs: MCP_SERVER.md, CONFIGURATION.md, Helm README, README, mcp and
migrations AGENTS.md, CHANGELOG (en/zh).
* docs(changelog): link the MCP OAuth token store entry to #7207
* fix(mcp): prune removed connections' OAuth token rows and ask owners to re-authorize on invalid_grant
Review follow-up (willem-bd):
- Both MCP config writers drop mcp_oauth_tokens rows of connections a
save removes (deployment: _commit_mcp_config_write; personal:
_mutate, keeping each connection's enabled/disabled runtime-name
variants so a toggle keeps its chain). Best effort; no startup sweep,
since a missing config file would look like every server removed.
- invalid_grant on a refresh_token request raises
McpOAuthReauthorizationRequired: the tool error names the server and
asks for a new refresh token, plus the shared-key hint when this
instance could not decrypt the stored chain.
- Annotate the gateway helpers' config as AppConfig.
* fix(mcp): renew the OAuth refresh lease, keep unstored rotations, and key access tokens by request parameters
Review follow-up (willem-bd, second round):
- HTTPX timeouts bound each I/O wait, not a whole response: the refresh
holder now renews its lease every third of REFRESH_LEASE_SECONDS while
the token request runs and abandons it after REFRESH_MAX_SECONDS (120 s);
waiters outlast a live holder. Regression uses a real loopback endpoint
that streams its body for three lease lengths.
- A refresh whose tokens could not be stored keeps them pending
(unsaved_base_version): they are written back before an older stored
token is adopted or refreshed with, retried every few seconds while the
access token is still valid, and dropped once a peer stored a newer
chain. A failed save releases the lease.
- New token_request_fingerprint (extra_token_params and response fields):
a stored access token is reused only under the same request parameters;
otherwise the stored refresh-token chain is refreshed.

* fix(memory): persist the DeerMem extraction watermark across restarts and replicas
The updater's per-thread extraction watermark lived only in an in-process
LRU, so a restart or a second Gateway replica on the same storage root fed
already-extracted turns to the memory LLM again.
FileMemoryStorage now keeps it in users/{user}/agents/{agent}/.metadata/
watermarks.json, keyed by thread id, written atomically under the per-user
lock without touching memory.json and capped by watermark_max_keys. Each
update feeds after the furthest of the LRU entry and the persisted one, and
writes through after an extraction or a pre-screen skip; bypass_watermark is
unchanged and sidecar IO failures fall back to the LRU. Memory clears remove
the file with the other .metadata sidecars. Content-based message identities
are stored as SHA-256 digests so the sidecar holds no conversation text.
* docs(changelog): link the memory watermark entry to #7204 and #7205
* fix(memory): never replace an unreadable watermark sidecar
set_extraction_watermark rewrites the whole watermarks.json, and the shared
sidecar reader turns an OSError into an empty mapping, so a failed read could
replace every other thread's watermark with the current one (or delete the
file). The watermark sidecar now has its own reader: a missing file reads as
empty, malformed content reads as empty (nothing to keep; the next write
repairs it), and any other OSError propagates before anything is written. The
updater already logs that and keeps the extraction successful.
* fix(memory): keep the persisted watermark when the last message has no identity
_message_identity returns None for a last message with neither an id nor
text. The updater wrote that None through, which deleted the thread's entry
from watermarks.json, losing a watermark a peer may have advanced and forcing
a full feed on every replica. The write-through now skips None: the persisted
entry still marks an extracted prefix and the furthest-of-both read keeps
using it.
* fix(channels): keep staging cleanup from replacing the save error
The channel stores publish state through a staged temporary file and, if the
rename fails, close and unlink that file inside the handler before re-raising.
Neither step was guarded, so a failing close skipped the unlink and a failing
unlink replaced the error that actually caused the save to fail -- leaving the
staged copy, which for the runtime-config and WeChat stores holds an 0600 IM
token, behind with nothing reporting it.
Make both steps independently best-effort, name the leaked file in a WARNING,
and suppress the diagnostic itself so a broken log handler cannot become the
reported failure. This is the same contract PR #6871 establishes for browser
captures, applied to the three JSON publishers in app/channels.

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

* fix(multi-instance): publish skill_manage cache resets and tolerate a concurrent namespace create
Two leftovers from the multi-instance work (#7097).
The agent's skill_manage tool refreshed only its own process's skills
prompt cache after a create, edit, patch, delete, write_file or
remove_file, so a Gateway replica sharing the home volume kept rendering
that user's previous skill list. Every mutation now runs one drained tail,
as the skill routes do: the write and its history record, the local
refresh, then publish_skills_cache_reset(user_id=...) off the event loop.
A run cancelled while the write is in flight still refreshes and
publishes before the cancellation propagates. A marker that cannot be
written is logged inside the tail and raised as SkillCacheResetPublishError
with a message saying the change was applied, so the model does not retry
a write that succeeded.
Two provisioner replicas starting together against a missing
K8S_NAMESPACE both read 404 and both create; the loser's 409 escaped the
lifespan and crashed it. A 409 on create now counts as the namespace
existing, as the Pod and Service creates already do.
Also drops a stale duplicate of the multi-instance "declaration also
drives" note in CONFIGURATION.md.

* fix(memory): filter honcho search by category instead of stamping it on unfiltered results
HonchoMemoryManager.search sent an identical unfiltered query whether or
not a category was requested, then stamped the requested category on
every hit, so memory_search(category=...) returned unfiltered results
attested to be that category (e.g. a work fact labeled "preference")
— the opposite of the contract, where category filters before the
top_k slice and only facts with that exact category are returned.
Send the category as a real server-side metadata filter (Honcho applies
"metadata" filters in its ranked query, before the limit) and label
each result from the record's own metadata, falling back to "memory"
as before. HonchoClient.search gains a keyword-only filters argument
that is only put on the wire when set, so unscoped requests are
byte-identical to before.
* docs(memory): note honcho category filtering requires stored metadata
* feat(channels): share encrypted runtime channel config across Gateway instances
IM bot credentials entered in the web UI lived in each host's plaintext
channels/runtime-config.json, and the router cached the merged config on
app.state for the life of the process. With several Gateway instances a
save or disconnect served by an instance that does not hold the
provider's leader lease never reached the transport holder: it kept the
old credentials until it next started the channel, and a disconnect
could leave the old bot connected.
- New shared table channel_runtime_configs (migration 0044): one row per
provider with the config block encrypted under DEER_FLOW_CREDENTIALS_KEY,
a plaintext disconnect tombstone, and a version bumped by every save.
- SqlChannelRuntimeConfigStore replaces the JSON file for sqlite/postgres
(memory keeps the file); it is synchronous on app_sync_sqlalchemy_url
because its callers already run in worker threads.
- The router re-reads the store on every request instead of caching the
merged config, and refuses (503) to save credentials without a key.
- The leader-lease supervisor compares the versions on each renewal tick
and restarts or stops the holder's transport when a provider's config
changed; a takeover reads a disconnect instead of reviving cached
credentials.
- The first start imports an existing runtime-config.json (rows already
in the table win) and deletes the plaintext file.
* docs(changelog): reference #6988 for the shared runtime channel config
* ci: rerun checks after #6999 fixed the frontend guidance budget on main
* fix(channels): start a held transport that is down when its runtime config changes
When the lease holder's transport was down (a start that failed on the
old credentials), applying a peer-saved config only updated the cached
config, and the transport started on the next lease round: two renewal
ticks instead of the one the docs promise. The apply step now starts it
on the held lease right away, with the lease round's backoff bookkeeping.
