Problem

A provider session is removed from the live map before its scope finishes closing. Reopening the same key can start a replacement while the old provider is still shutting down. Repeated close or exclusive detach can also return before teardown finishes.

Change

Register a release deferred atomically with removal. Reopening waits for the old scope to close or the existing 30-second bound to fire. Repeated close/detach joins that release. Teardown owns its lifetime, so cancelling its caller cannot free a still-closing key.

open checks the barrier again after asynchronous workspace checks. ensureThread, resumeThread and forkThread reject retired runtimes and leave replacement bookkeeping alone. Exclusive detach preserves thread-wide credential revocation even when another release wins removal, and still omits the detached thread from stopped-session status updates.

Scope

This is the smaller replacement Julius requested on #11492: a releasing map, waiting or rejection at session entry points, joined teardown, and the unchanged close timeout. The obsolete PR remains closed.

Only ProviderSessionManager.ts and its existing test file change (+682/−180, including moved teardown code and regression coverage). This exceeds the suggested approximately 300-line target; the additional cases cover cancellation, the workspace-stat gap, retired runtimes and detach credential/status consistency. There are no adapter or startup-worker changes.

Verification

Current candidate 1c9dfe3, tree 2a631bcf3c7b79f9f8ea469a5b6d05abf89a4a21, integrates main a472342 without rewriting prior author commits.

• CI=true TMPDIR=/private/tmp vp run check:changed upstream/main passed format, lint, knip, affected-package typechecks and 82/82 session manager and replay integration tests. All commands retained their actual exit status. No repo-wide test run.
• Fresh independent read-only review by GPT-6.1 Sol/high, Codex through T3 Code: no actionable P1/P2/P3 findings in the full frozen contribution. Task node:delegated-task:command%3Amcp%3A05f1a96a-5b49-41a2-bc99-96140e5986df%3Adelegate-task%3Afinish-t3-four-repairs-review-20261114 completed. It inspected source and test receipts without rerunning the suites.
• Fresh readback: all eight required checks are satisfied (five success, three skipped). Macroscope correctness passed. Macroscope approvability approved this exact head. Earlier captures do not certify this head. Native/client, remote/relay and paid-provider runtime proof were not repeated for this conflict repair.

Historical verification and retained author credits (earlier revisions)

Verification

Integrated onto main at 2b07556, verified in an isolated Linux Boat sandbox:

• The two original race tests failed on unchanged main before implementation: a replacement reached the adapter while the old scope was closing, and repeated close/detach returned before the close bound. Those failing-first runs preceded this main integration.
• Additional failing-first cases cover reopen during workspace stat, cancellation of the initiating close, four retired-runtime load paths, repeated exclusive detach, and detach status events. The last regression races close against detach: before repair, an unrecorded credential for the deleted thread still resolved; the repaired candidate revokes it.
• Final manager suite: 75 passed. The added fork row first failed on the published head: both retired calls succeeded rather than rejecting; it passes with runtime checks at attachment and native load. Exact-tree CI=true vp run check:changed: exit 0; 77 tests in two files, three package typechecks, format, lint, knip twice and GraphQL. Local and Boat trees and both file hashes match (66ab84a33cd6ed2d47cefde003f6277ae05fa636). Fresh independent review of the complete contribution after the fork repair found no actionable findings.
• All runtime evidence is the manager harness with a fake provider and SQLite. No real provider process, client or connection mode was exercised. Current revision: fb036f5. All 35 check runs on this head completed with success or skipped (23 successful, 12 skipped). Macroscope approved this head, CodeRabbit reports no actionable findings and confirms the fork repair, and no review threads remain unresolved.

Independent review: Claude Opus 5.5 in Claude Code through T3 Code, task a1e57c9f-b503-4554-a550-64aaa8a9166d, completed with no defects on the fork delta or full two-file tree. High effort was configured; the reviewer reported a low harness setting, so effective high effort is not claimed.

Approvability

Verdict: Approved at e2dd87a

Macroscope's review found this PR approvable — Session reopen and repeated release operations now wait for teardown, while stale runtime handles are prevented from affecting replacement sessions. Existing cleanup and close-timeout safeguards remain, with no product-default or diagnostic-suppression changes.

Walkthrough

ProviderSessionManager now coordinates session teardown by session ID and waits for teardown before reopening or completing detach. Thread operations verify runtime identity. Tests cover teardown races, concurrent close and detach, credential revocation, and operations on stopped runtimes.

Changes: Session lifecycle

Layer / File(s)	Summary
Release coordination and teardown apps/server/src/orchestration-v2/ProviderSessionManager.ts, apps/server/src/orchestration-v2/ProviderSessionManager.test.ts	Release runs independently of the initiating caller and signals completion after cleanup. Opening and detach operations wait for an in-progress release. Tests cover reopening races, concurrent close and detach, and credential revocation.
Runtime identity checks apps/server/src/orchestration-v2/ProviderSessionManager.ts, apps/server/src/orchestration-v2/ProviderSessionManager.test.ts	Thread loading, attachment, resumption, and related state updates verify that the runtime remains current. Tests check that operations fail while the runtime is closing or after it is retired.

Merge Risk: Minimal · up to e2dd8

This change makes provider session teardown finish before a replacement session can start, and makes repeated close or detach wait for the same teardown. No unresolved defects were found, and the race and retired-runtime cases have regression tests. It looks ready to merge.

Full details: Title check

Explanation

The title "fix(server): wait for provider sessions to finish closing" follows conventional commit form and names the main change. The PR makes reopening and repeated close or detach wait for the old provider session scope to finish closing, which matches the objectives and the ProviderSessionManager changes.

Full details: Description check

Explanation

The description follows the template's main sections: Problem, Change, Scope, and Verification. It explains the race, the release barrier, the single-file scope with its line-count overage, and the verification commands and results, including the 82/82 test run and the historical failing-first runs. Verification relies on a fake provider and SQLite harness, and the description says that no real provider, client, or connection mode was exercised. The template's leading conventional-commit guidance is satisfied by the title. The historical verification section has some noise and mixes revision references, but the required information is present.

Merged current main without rebasing in e2dd87ad54. Resolved the teardown conflict by preserving this PR's release barrier and keeping main's native subagent cleanup in both release-record and post-drain paths. The contribution remains scoped to the same two files. The earlier retired-runtime fork finding was already addressed and remains covered.

Blacksmith vp run check:changed passed: formatting, lint, knip, GraphQL, typecheck for three affected packages, and 82 tests, including all 80 ProviderSessionManager tests. The worker's shallow snapshot needed its comparison ancestry restored; the check selected only the two contribution files. Two independent read-only reviews approved this head.

All 36 reported checks passed, with no pending checks or conflicts. Live provider/client teardown was not exercised in this pass; verification used the existing service behavior tests and CI.
