Test fixes in the follow-up commits:
Upstream's new []weightedPoolMember shifts in sdk/cliproxy/auth/selector_weighted.go tripped TestInPlaceByteWritesAreReviewed. They move structs, not payload bytes, so I added them to the reviewed list.
TestServerRejectsIncompleteUnauthenticatedRequestBodiesPromptly timed out after 500ms when the full suite ran. It fails the same way on origin/main. A goroutine dump showed the handler stuck in CreateFile while the request logger opened the body temp file, which stalled for more than 5s under heavy parallel I/O. I raised the deadline to 15s, which is still enough to catch a real hang.
TestAntigravityBlockedHintPersistenceDoesNotBlockPublicationOrOtherAccounts closed releaseSave twice when it timed out. The panic hid the real failure message. I removed the second close and raised its 1s limits to 5s.
The management OAuth tests polled in a busy loop with no pause, which starved the flow they were waiting on. The loop now pauses between polls, and the 5s deadlines are now 15s.
TestHandleEventConfigChangeSchedulesReload used a fixed 400ms sleep. It now polls until a deadline.
TestHandleAuthUpdates_SameRevisionWaitDoesNotWaitForOtherAuthInBatch assumed auth B always reaches the test hook second, but registrations run in parallel. It failed about 1 run in 400. On timeout, its cleanup also leaked B's models into the shared registry, which failed the two TestEndToEndAuthFile*_RestoresModels* tests. The test now detects which auth finished, and cleanup waits for the batch. 0 failures in 5,400 runs.

…ion under session affinity
- Document in config.example.yaml and RoutingConfig.SessionAffinity that Merkle LCP compaction matching requires at least 2 shared trailing turns.
- Note that clients whose compaction replaces all earlier turns with a summary should send X-Session-ID or another explicit session ID to preserve credential affinity.

…ipeline
- Treat thinking.display="updates" as an enabled reasoning summary mode when extracting Claude summary configuration so translated requests emit target visibility controls such as Antigravity includeThoughts.
- Preserve an existing "updates" display mode when applying enabled summary configuration back onto Claude request documents instead of overwriting it with "summarized".
- Add unit and cross-protocol translation regression tests for Claude thinking.display="updates".

Preserve an absolute heartbeat deadline across config,
cluster, and telemetry messages so ordinary subscription
traffic cannot mask a stalled heartbeat. Only an
empty-payload PONG renews liveness and resets reconnect
failures, and messages arriving after the deadline are
treated as timeouts
…ool calls
- Add a single-space reasoning_content placeholder on assistant tool-call turns without replayable thinking text when is-compat and request reasoning are active.
- Reconcile tool-call placeholder reasoning after canonical thinking resolution so model suffixes and capability normalization govern final inclusion before payload rules.
- Add unit and executor regression tests covering absent/whitespace thinking, disabled thinking, suffix overrides, and final payload overrides/filters.

…iptions
- Detect input_schema property keys outside Claude's ^[a-zA-Z0-9_.-]{1,64}$ pattern by walking JSON Schema subschema positions in tools[] and inline tool_addition definitions.
- Replace affected schemas with an open object and embed the original schema in the tool description before payload rules, so parameters keep their exact names without request or response rewriting.
- Apply the fallback on execute, stream and count_tokens paths with regression tests for Responses and native Claude sources, MCP aliasing and payload-rule ordering.

…te from summary requests
Clear top-level text format constraints and filter configuration_update control items when preparing local compaction summary payloads so structured JSON schemas do not overwrite the summary output.
- Accept both cli and cli-bg in the native X-App header check so Claude Code background sessions preserve their native request identity instead of receiving the pinned device profile rewrite.
- Add unit and executor regression tests verifying native detection and passthrough for X-App: cli-bg across messages, streaming, count_tokens, and measured helper requests.

- Pause between OAuth status polls and widen the deadline to 15s so the

- Widen Devin remote OAuth bounds from 5s to 15s.
- Replace the fixed 400ms sleep in the watcher config reload test with a

The pull request adds local Codex compaction, bounded deferred API logging, configurable sensitive-word replacements, and Claude fallback reporting. It also updates cooldown and weighted-selection state, timed model suspensions, heartbeat handling, XAI stream errors, Meta prompt-cache passthrough, and provider model records.
Changes: Configuration and Claude request handling
Layer / File(s)
Summary
Cloak configuration and persistence config.example.yaml, internal/config/*, internal/watcher/diff/*, internal/api/handlers/management/config_v8_test.go
Configuration now includes sensitive-word replacement maps and the Claude server-side-fallback setting. Parsing, normalization, comment-preserving saves, management coverage, and change summaries include these settings.
Sensitive-word matching and application internal/runtime/executor/helps/cloak_obfuscate*, internal/runtime/executor/helps/devin_wire*, internal/runtime/executor/antigravity_executor*, internal/runtime/executor/claude_executor*, internal/runtime/executor/devin_executor*, internal/auth/claude/identity.go
Matchers support literal replacements and provider-specific obfuscation. Claude Home metadata, Antigravity, Claude, and Devin use replacement configuration in their request paths.
Claude fallbacks and tool/reasoning translation internal/translator/claude/*, internal/translator/common/claude_native_response.go, internal/runtime/executor/helps/claude_tool_property_names*, internal/runtime/executor/helps/model_capabilities*, internal/thinking/summary*
Claude responses expose serving-model and fallback-chain metadata. Claude tool schemas normalize unsupported property names, and Claude-to-OpenAI compatibility requests update reasoning placeholders and thinking-display handling.
Codex local compaction
Layer / File(s)
Summary
Compaction recognition and executor flow internal/runtime/executor/helps/antigravity_compaction*, internal/runtime/executor/codex_executor_*, internal/runtime/executor/codex_openai_images.go
Compatible Codex Responses requests can use local summary compaction. Executor paths expand capsules, handle synthetic IDs, publish usage, and return compacted responses.
Duplex WebSocket compaction and continuation internal/runtime/executor/codex_websockets_duplex*, internal/runtime/executor/codex_websockets_stream.go, sdk/cliproxy/executor/context.go
Duplex sessions track local compaction results and response state. Valid synthetic parents expand into new requests; unavailable parents return a conflict.
WebSocket boundaries and integration coverage sdk/api/handlers/openai/openai_responses_websocket*, sdk/api/handlers/openai/openai_responses_steering_integration_test.go
The handler records local turns and compaction boundaries, then routes continuations using that state. Tests cover local compaction, fresh-root continuation, and rejected prior response IDs.
Request-scoped capture stores bounded upstream request and response details, masks headers, and renders captured data for forced error logs. Middleware and API handlers attach, inherit, and close captures.
Executor response and WebSocket failure capture internal/runtime/executor/*, internal/runtime/executor/helps/logging_helpers.go, internal/util/provider.go
Executor response paths record bytes returned alongside read errors. WebSocket rejection paths record handshake responses and errors when ordinary request logging is disabled.
Cooldown state now retains force-cooldown deadlines and Claude quota signals across runtime updates and persistence.
Cooldown selection and response headers sdk/cliproxy/auth/selector.go, sdk/cliproxy/auth/scheduler.go, sdk/cliproxy/auth/conductor_selection.go, sdk/api/handlers/claude/code_handlers_cooldown_test.go, sdk/cliproxy/auth/conductor_selection_cooldown_test.go
Selectors calculate cooldown availability and Claude unified rate-limit headers from retained signals and deadlines. Tests cover header passthrough and cooldown cases.
Request rules and weighted selector state sdk/cliproxy/auth/conductor_request_scoped_errors.go, sdk/cliproxy/auth/conductor_execution.go, sdk/cliproxy/auth/conductor_stream.go, sdk/cliproxy/auth/selector_weighted.go, sdk/cliproxy/service_config.go
Request-scoped rules travel through execution contexts. Scheduler rejections affect retries and fallback handling. Weighted pools use route, priority, and transport scope, and selector state can persist across configuration changes.
Model availability and subscription heartbeat
Layer / File(s)
Summary
Timed model suspensions internal/registry/model_registry.go, internal/registry/model_registry_transient_suspend_deadline_test.go, sdk/cliproxy/auth/conductor_models.go, sdk/cliproxy/auth/conductor_models_transient_projection_test.go
Model projections can include suspension deadlines. Registry availability calculations and cleanup account for expired suspensions and quota recovery.
XAI Responses parsing handles terminal errors, empty streams, and streams without terminal responses. Tests cover status mapping, usage outcomes, and partial response logging.
Meta prompt-cache passthrough and model records internal/runtime/executor/meta_executor_*, internal/registry/models/models.json
Meta requests preserve valid explicit prompt_cache_retention values and remove invalid values. Payload rules can provide, replace, or filter the field. Model records add Gemini and Meta entries.
Provider response paths retain available bytes on read errors. The changes also cover X-App: cli-bg, Claude thinking display updates, and WebSocket keepalive handling.
Security architecture risk: Moderate · up to 3ea23
The update expands upstream data retained after failures and changes how shared credentials recover from cooldown. Existing error-only logging controls and cleanup reduce exposure, but failure recovery and continuation behavior are not fully established. No newly introduced exploit was confirmed.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The newly established exposure is upstream response information reaching error diagnostics when full request logging is disabled. Capture is request-scoped, not a shared cross-request store. Actual diagnostic-reader privileges, retention, and deployment-level access controls were not established, so credential theft or cross-tenant disclosure is not asserted.
Trust Boundaries and Controls
observed — The named public-entrypoint change increases only the test client's deadline from 500 milliseconds to 15 seconds. The inspected production multiplexer and server files have no changes in the full PR comparison. The test still fails on a read timeout and checks the expected response and connection closure; this signal does not establish a new authentication bypass.
observed — With request logging disabled, finalization requires an actionable error or panic to force logging; otherwise it discards the log path and runs deferred cleanup. This is meaningful counterevidence against routine successful requests being persisted through the newly added response-capture path.
Resilience and Maintainability Implications
observed — Cooldown restoration mutates credential state under the manager lock, publishes scheduler snapshots after releasing that lock, and then persists the result. Identity and expiry guards are visible, but this inspection does not establish atomicity across storage and scheduler publication or correctness across every concurrent recovery transition.
Hardening Proposals
proposed — Consider complete suppression or cookie-aware redaction of cookie credentials in the expanded diagnostic path, and explicitly define the permitted retention of raw upstream response bodies. These are hardening proposals, not verified credential-disclosure findings.

Explanation
The title "chore: sync upstream through 8bba7a7" names the primary change: merging 26 upstream commits through 8bba7a7 into the fork. The changeset is a large upstream sync that touches many areas (config, executors, auth cooldown, registry, websocket handling, and tests), and the title identifies the sync itself without listing those areas. The title is short, specific to the sync, and free of file lists or vague wording. It does not describe every detail, which the check does not require.

A goroutine dump of the failing run showed the handler blocked in CreateFile

response bytes were written. Under heavy parallel test I/O this exceeded 5s.
If auth.Attributes["cloak_sensitive_words"] contains proxy and metadata contains the slice ["other"], this branch selects other. The configured attribute word then reaches the upstream request unchanged. Check the attribute first and use the metadata slice only when the attribute is absent.

Exclude the injected Claude Code identity from replacements.
The new test configures "Claude Code": "Claude Assistant".

Advertise the output limit supported by the Vertex execution path.
max_completion_tokens: 1048576 is exposed as a model output limit. The Vertex executor uses a single v1 request and does not follow a continuation token.

Apply the credential-quota deadline to model suspensions regardless of reason.
The reason check at line 310 skips the credential-quota deadline for non-quota model cooldowns. The selector applies that deadline to every matching model under a live credential quota (selector.go:1293-1310). When a model has a non-quota cooldown ending at T1, and the credential quota ends later at T2, the projection sets SuspendUntil to T1. The selector still blocks the model until T2. The registry can therefore list the model as available before it can be served.
A model-scoped failure reported while the credential quota is live can produce this state. That failure is applied to an unwrapped model state (conductor_cooldown.go:1597-1605).

298-299: Minor · Functional Correctness · Heavy lift
Reject stale candidate versions before the weight-change branch updates pool state.
prepareWithVersions stores the incoming registration version in the weight-change branch without comparing it to the stored version. The other two branches compare versions first. A candidate captured before a newer registration can therefore lower regEpoch and regGen for a pool member. For example, a stored (epoch=2, generation=20, weight=2) followed by a stale (1,10,1) stores (1,10). A later ForgetAuthUpTo(id, 1, 10) then matches that member and can delete the pool, which resets its credits.
The window exists because availableAuthsForSelector runs under m.mu.RLock(), and the lock is released at conductor_selection.go:2353 before selector.Pick at :2366. The same pattern appears at :2808 and :2839. A registration can commit in that gap. The captured pointers then reach extractWeightedAuthVersions inside reservePoolScoped at selector_weighted.go:358.
The dynamic path has a related gap. At selector_weighted.go:613, s.members[index].weight = weights[i] runs for an incoming version older than the stored one. The guard at lines 614-618 keeps the newer version, so the older weight stays attached to it.
Ignore candidate versions older than the stored member version before changing weights or credits. Apply this check on both the exact-pool and dynamic paths.

Apply the credential force deadline to the active quota window.
If a forced credential-scoped 429 has no RetryAfter, Lines 1737-1741 can calculate a force deadline later than a nearly expired ordinary credential-quota window. This assignment saves that later deadline, but credentialNext, auth.Quota.NextRecoverAt, and the propagated retry times retain the earlier deadline.
Selection in sdk/cliproxy/auth/selector.go (Lines 1255-1357) still uses those earlier availability deadlines. The auth can therefore become selectable before credQuotaForceUntil.

Preserve the headers in the saved force-cooldown state.
If a Claude auth has an auth-level forced quota cooldown and at least one model state, a disable-cooling reload saves the quota here, clears it at Line 957, and restores it at Line 969.

The force-preservation branch runs only when the incoming NextRetryAfter has already expired. If an unchanged-credential replacement carries a future NextRetryAfter, the branch is skipped. forceCooldownUntil is unexported and not serialized, so the incoming Auth cannot carry it. The replacement then clears the active force deadline, and the credential can become selectable at the earlier persisted retry time.
Keep the force deadline independent of the incoming retry deadline in this path. The other fields in this branch (Unavailable, NextRetryAfter, LastError, StatusMessage, Status) depend on the retry deadline. Decide how to combine them before changing the guard. A single-line patch would change that behavior, so no patch is proposed.

Update the unchanged-credential replacement handling keyed by updateModeReplace so an active existing.forceCooldownUntil is preserved even when the incoming auth.NextRetryAfter is in the future. Before changing the guard, separate force-deadline preservation from the retry-dependent handling of Unavailable, NextRetryAfter, LastError, StatusMessage, and Status; establish and preserve the intended behavior of those fields rather than changing it as a side effect.

Do not extend quota signals to a longer non-quota force deadline.
An auth-only forced 503 for 10 minutes can overlap a later, one-minute credential quota. MarkResult preserves both deadlines. This branch returns the credential quota’s signals without checking the longer auth force deadline. isAuthBlockedForModelForRequest returns 10 minutes, and appendClaudeUnifiedHeaders rewrites the quota reset to that deadline. The response then falsely reports a 10-minute subscription quota. Omit unified headers when the longer, non-quota force deadline governs. (raw.githubusercontent.com)

Preserve longer auth-only retry deadlines.
If an auth-only forced 503 sets a one-minute force deadline and another in-flight 503 extends NextRetryAfter to 10 minutes, this assignment still returns one minute. applyAuthFailureState preserves the shorter force deadline independently. With no ModelStates, the credential remains blocked for 10 minutes, so Retry-After instructs clients to retry too early. Include the longer auth-level retry and quota deadlines when no model states exist. (raw.githubusercontent.com)

Stop retrying when a scheduler rejection ends the round.
If an upstream attempt returns a retryable 503 and the next credential pick is scheduler-rejected, roundPickFailureError returns the prior 503 with a round-ended marker. Execute then passes that error to shouldRetryAfterErrorWithAttempted. That policy checks for a scheduler-rejection error but not the round-ended marker, so it can start another round despite the rejection. The same path exists in ExecuteCount and ExecuteStream.

Project auth-level forced cooldowns even when model states exist.
If auth.ModelStates is non-empty, this guard skips credential-wide availability. A model-less forced-cooldown result can leave an auth-level force deadline active alongside those states. The selector blocks every model until that deadline, but an unmatched model receives an unsuspended projection. The registry can therefore list a model that its only credential cannot serve. Include the active auth-level force deadline regardless of model-state count. (raw.githubusercontent.com)

Build restored shards without rebuilding indexes after every insertion.
When rebuild runs after several models have been used, this call eagerly recreates their shards while s.mu is held. ensureModelLocked inserts each auth through upsertEntryLocked, which calls rebuildIndexesLocked for every new entry. Each shard therefore performs quadratic entry scans plus repeated sorts and allocations. Large credential pools block scheduler picks throughout this work. Build each shard in bulk and rebuild its indexes once, or retain cursor snapshots for lazy restoration. (raw.githubusercontent.com)

Registration workers run in parallel, so either auth's task can be the
second to reach modelRegistrationTaskHook. The test assumed it was always
auth B; when auth A was blocked instead, the same-revision wait for A
timed out (about 1 in 400 runs). Detect which auth actually finished.
On timeout, cleanup released the blocked registration after the client
was unregistered, leaking models into the global registry and failing the
EndToEndAuthFile*RestoresModels tests. Cleanup now waits for the batch
before the registry cleanup runs.
The reason will be displayed to describe this comment to others. Learn more.
Blocked models remain listed
clientModelProjectionForAuth skips account-wide cooldown checks whenever ModelStates is nonempty. This misses the new forceCooldownUntil block. An SDK caller can record a model-less forced cooldown through MarkResult after earlier model requests, as the new regression test does. Selection then blocks every model, but the registry can list models whose own cooldown has expired.
Include the active account-wide forced deadline in the projection even when model states exist. This keeps /v1/models from advertising models that still reject requests.
The intermittent "token exchange did not start" came from a Windows sharing
violation when reading the callback file, not from a tight bound. The fix and

[]weightedPoolMembershifts insdk/cliproxy/auth/selector_weighted.gotrippedTestInPlaceByteWritesAreReviewed. They move structs, not payload bytes, so I added them to the reviewed list.TestServerRejectsIncompleteUnauthenticatedRequestBodiesPromptlytimed out after 500ms when the full suite ran. It fails the same way onorigin/main. A goroutine dump showed the handler stuck inCreateFilewhile the request logger opened the body temp file, which stalled for more than 5s under heavy parallel I/O. I raised the deadline to 15s, which is still enough to catch a real hang.TestAntigravityBlockedHintPersistenceDoesNotBlockPublicationOrOtherAccountsclosedreleaseSavetwice when it timed out. The panic hid the real failure message. I removed the second close and raised its 1s limits to 5s.TestHandleEventConfigChangeSchedulesReloadused a fixed 400ms sleep. It now polls until a deadline.TestHandleAuthUpdates_SameRevisionWaitDoesNotWaitForOtherAuthInBatchassumed auth B always reaches the test hook second, but registrations run in parallel. It failed about 1 run in 400. On timeout, its cleanup also leaked B's models into the shared registry, which failed the twoTestEndToEndAuthFile*_RestoresModels*tests. The test now detects which auth finished, and cleanup waits for the batch. 0 failures in 5,400 runs.go buildand 3 back-to-back runs ofgo test ./...pass locally on Windows.Summary by CodeRabbit
