Problem

Saving provider credentials can leave an existing chat using the old environment until the app restarts. The provider instance is rebuilt, but ProviderSessionManager.open returns the cached runtime before consulting the current adapter. Claude's runtime retains the environment captured by the previous adapter.

Fixes #31249.

Change

On the next idle session open, compare the cached adapter with the current instance's adapter. If it changed, release the old runtime and reopen through the existing native-session resume path. Defer replacement while turns, background work, or sibling runs are active, including siblings still starting. A failed background-work probe conservatively keeps the session.

Cache auth-guard wrappers per provider instance so repeated registry lookups have stable adapter identity. This prevents unchanged instances from being mistaken for replacements.

Scope and approval

This is a focused fix for stale provider configuration: settings already rebuild provider instances, and session reuse currently bypasses that rebuilt instance. It adds no setting, contract, or provider feature. Submitted under the focused obvious-bug exception; the linked report has not yet been maintainer-triaged.

The comparison applies to any provider-instance configuration replacement, not only credentials. Registry lookup failures now surface as session-open errors rather than reusing obsolete configuration. That is intentional, including the transient interval while an instance is rebuilding.

Verification

Added a synthetic regression that opens a session with an empty token, replaces the registry adapter with one capturing a saved test token, and reopens the same session. Before the fix, the second adapter was never opened; afterward, it is opened with the original native thread and resume state.
Added background-work, failed-probe, and sibling-startup cases. The sibling-startup case failed before its guard was added and now passes. Extended the busy-sibling test to verify an adapter replacement does not interrupt an active turn.
Extended the auth-guard registry test to verify stable identity within one instance and changed identity after instance replacement.
vp run check:changed origin/main: formatting, lint, both knip checks, affected GraphQL checks, typechecking for 3 packages, and all 59 tests across 3 affected test files passed.

Focused runtime-fixture transcript:

text

1	vp test run apps/server/src/orchestration-v2/ProviderSessionManager.test.ts -t 'refreshes provider credentials' --reporter verbose

3	PASS idle
4	PASS background
5	PASS probe-error
6	PASS sibling-starting
7	Test Files 1 passed (1)
8	Tests 4 passed \| 50 skipped (54)

The transcript uses fake provider runtimes; a packaged desktop build and live provider calls with this patch were not tested. Review also noted that non-turn maintenance such as a concurrent rollback is not represented by the existing busy-turn guard; that shared-runtime concurrency case remains outside this patch's verification.

Approvability

Verdict: Approved at 5002ca3

Macroscope's review found this PR approvable — Idle provider sessions will pick up changed provider settings on their next open, while active or background work prevents refresh. Stable adapter identity and existing lifecycle guards limit unnecessary restarts and interruption risk.

Walkthrough

The registry caches auth-guarded adapters by provider instance. The session manager records the adapter used by each live session and checks for pending work before replacing a session after an adapter change.

Changes: Provider session refresh

Layer / File(s)	Summary
Cache guarded adapters by provider instance `apps/server/src/orchestration-v2/ProviderAdapterRegistry.ts`, `apps/server/src/orchestration-v2/ProviderAdapterRegistry.test.ts`	Repeated lookups reuse the guarded adapter for the same provider instance. The test verifies that a replacement instance returns a different adapter.
Refresh idle sessions after adapter changes `apps/server/src/orchestration-v2/ProviderSessionManager.ts`, `apps/server/src/orchestration-v2/ProviderSessionManager.test.ts`, `apps/server/src/orchestration-v2/testkit/*`	The manager looks up the current adapter before checking for a live session. If the adapter changed, it releases the session only when no busy turns, pending background work, or other working threads remain. Tests cover refreshed sessions, session-resume inputs, continued runtime reuse, and stable adapter wrappers.

Refreshing an idle session after a provider settings change works for the tested cases. Two narrow edge cases remain: a pending unanswered prompt could be dropped on refresh, and a rare cleanup failure could fail a single open that would succeed on retry. Both are worth addressing but are not serious blockers.

Full details: Linked Issues check

Explanation

Issue #31249 requires replacement configuration on the next idle open, native-session continuity, and protection for active turns and pending work. ProviderSessionManager.ts now compares the cached adapter with the current adapter and releases a stale idle session only when the background-work probe and sibling-run checks allow it. Probe failures conservatively defer release. The normal reopen path receives the resume input and native thread ID. ProviderSessionManager.test.ts covers idle refresh, background work, probe failure, sibling startup, and reuse during a busy turn. ProviderAdapterRegistry.ts caches auth-guard wrappers by provider instance, so unchanged instances keep stable adapter identity.

Full details: Out of Scope Changes check

Explanation

All reviewed changes support issue #31249. The registry wrapper cache enables reliable adapter identity checks. The session-manager logic and tests implement and verify safe idle refresh. The test-harness wrapper caches prevent repeated lookups from appearing as provider replacements. No unrelated feature or change appears in the reviewed diff.

test(server): keep replay registry wrappers' adapter identity stable942ead0
Merge remote-tracking branch 'github/main' into fix/provider-secret-refreshc4c3aa4

Mmaria6d ago

Note

Written by claude-opus-5-5 on behalf of Maria

Takeover fixup:

Test Server 3 and Test Server 5 failed because two replay test wrappers (ThreadMergeBack.integration.test.ts, OpenCode2PendingSnapshots.evidence.test.ts) built a new adapter object on every registry.get. With this PR's adapter identity check, each reopen looked like a settings change and released the live session. The wrappers now memoize per inner adapter, matching what the production registry does. No production code changed.
Merged current main again (merge commit, no rebase). It conflicted in ProviderSessionManager.open with main's linked-environments refresh (#26737). Both refreshes now run in order: the adapter-change release first, then releaseForLinkedEnvironments, using a single registry.get at the top of open.
check:changed passes (format, lint, knip, typecheck, tests), and apps/server/src/orchestration-v2 passes in full: 122 files, 2358 tests.

On CodeRabbit's outside-diff note about in-flight rollbacks (ProviderSessionManager.ts:2189): the window is real but narrow. It needs a provider settings change and a sibling-thread open on the same shared session while a rollback's thread/revert is in flight. The proposed fix is a new session-level rollback reservation, which is a bigger change than this PR. It's left for a follow-up.

Keep the session scope open for in-flight rollbacks.
runsToRollback contains only settled runs, so the rollback effect is invisible to otherWorkingThreads. A sibling refresh can therefore close the scope that owns the Codex process while thread/revert is awaiting its response. Codex may apply the revert before the transport closes. The pending request then fails before CheckpointRollbackService.execute restores checkpoints and writes the new provider-thread state.
The worker retries the same effect, but the provider conversation may already have changed while the projection still describes the old conversation. If the final attempt fails, the effect records checkpoint.rollback.fail without reconciling that provider-side change.
Track rollback as session-level active work before sessions.open, keep the reservation through rollbackThread, and release it in cleanup. Make the refresh guard retain the entry while that reservation exists.

Add the unfinished-records guard before releasing on adapter change.

The refresh path decides on three inputs only:

the runtime probe hasPendingBackgroundWork,
otherWorkingThreads, which excludes input.threadId, and
busyTurns.

It never checks the following, which releaseForLinkedEnvironments (Lines 1833-1861) guards through keepIf: hasUnfinishedRecords:

Pending runtimeRequests whose responseCapability is live on this session.
pendingBackgroundTasks on the opening thread's own provider threads.

A runless request is one the pump persists directly, such as a project-trust or login prompt. It has no busy turn and no run. If the adapter changes while such a request is pending, releaseEntry expires or cancels it. The user has not answered it.

keepIf runs under requestEventPermit, so it also covers a runless request that is being persisted at that moment. The new path has no equivalent protection.

Extract hasUnfinishedRecords into a shared helper. Pass it as keepIf here.

Do not fail the open when the post-removal release bookkeeping fails.

releaseEntry removes the entry from the live map before it closes the scope and writes the release records. Any failure at Lines 2454-2462 therefore happens after the stale runtime is already gone. Examples are a SQL commit failure or a failed scope close. releaseEntry already schedules background retries for the records.

The new code maps the failure to ProviderSessionOpenError. The user's open fails once, although the next call would succeed because the entry is gone.

releaseForLinkedEnvironments handles the same situation with logReleaseFailure(providerSessionId). Use it here too. The flow then reaches the live and existing lookups and opens a fresh runtime.
