Problem

Server replay tests never delete their temp directories. makeReplayServerConfig in ProviderReplayHarness.ts creates a t3-orchestration-v2-replay-<scenario>-* tree (the base dir plus 8 subdirectories) with fs.makeTempDirectory, and nothing removes it. The Codex and Claude replay testkits build their server config through that helper, so every replay scenario run leaves one behind in the OS temp dir. The ACP registry, Grok and fx replay testkits each also leave a *-replay-<scenario>-* status directory.

The directories pile up on dev machines and long-lived CI runners. On one Linux machine that runs the server suite often, the temp dir held 11,758 t3-orchestration-v2-replay-*, 7,827 t3-orchestration-v2-codex-*, 384 Grok and 283 ACP registry replay directories.

Change

• ProviderReplayHarness.ts: makeReplayServerConfig uses fs.makeTempDirectoryScoped and lists Scope.Scope in its requirements. Callers build it through Layer.effect or inside it.effect, and both already supply a scope, so no call site changes.
• AcpRegistryAdapterV2.testkit.ts, GrokAdapterV2.testkit.ts and FxAdapterV2.testkit.ts: the replay status directory uses makeTempDirectoryScoped. These run inside layerFromAdaptersEffect, which already supplies Scope.

This matches the rest of apps/server/src, where makeTempDirectoryScoped is the usual form. CursorAdapterV2.testkit.ts already uses it in the same kind of layer.

Scope and approval

No issue. This is a small test-infrastructure fix: four swaps to the scoped variant and the type change they need. The app does not run any of this code, so nothing changes at runtime or on screen. The replay layers already run inside a scope, and the directory is now removed when that scope closes.

Verification

New test apps/server/src/orchestration-v2/testkit/ProviderReplayHarness.test.ts builds makeReplayServerConfig inside a scope, checks its state dir exists, closes the scope, and checks the base dir is gone.

cd apps/server
vp test run src/orchestration-v2/testkit/ProviderReplayHarness.test.ts

• With main's ProviderReplayHarness.ts: 1 failed, "expected true to be false", and the directory is still in TMPDIR.
• This branch: 1 passed.

The Codex, Claude, Grok, ACP registry and fx adapter test files (5 files, 476 tests) pass on this branch and leave no t3-orchestration-v2-* replay directories in TMPDIR. vp run check:changed passes (format, lint, knip, typecheck, tests).

Leftover counts from one pass of the 32 server test files that used these testkits, each run with its own empty TMPDIR, measured when this PR was first opened (base bd6940beab, before main moved the Codex testkit onto the shared helper):

Directory prefix	main (bd6940b)	this branch
t3-orchestration-v2-replay-*	399	0
t3-orchestration-v2-codex-*	98	0
t3-orchestration-v2-acp-registry-replay-*	15	0
t3-orchestration-v2-grok-replay-*	16	0

Not checked:

• macOS and Windows. I ran everything on Linux only.
• The full server suite.
• scripts/record-grok-acp-replay-fixture.ts was typechecked but not run, since it records against a live Grok agent.
• LegacyV1Cutover.integration.test.ts makes its own t3-v1-cutover-state-* temp dir in the test body. That is a separate test, so this PR leaves it alone.

Prior PRs: none found. No open or closed PR changes these temp directories.

Approvability

Verdict: Approved at 0d4347a

Macroscope's review found this PR approvable — This is a small, self-contained test-infrastructure fix that scopes replay temporary directories for automatic cleanup and adds focused coverage. The registry change is type-only, with no product runtime, schema, default, security, or deployment impact.

Walkthrough

Replay testkits now create temporary directories with scoped filesystem operations. The replay harness requires an Effect scope, and a test checks that its base directory is removed after the scope closes.

Changes: Replay directory scope

Layer / File(s)	Summary
Create and clean up scoped replay directories apps/server/src/orchestration-v2/testkit/ProviderReplayHarness.ts, apps/server/src/orchestration-v2/testkit/ProviderReplayHarness.test.ts, apps/server/src/orchestration-v2/Adapters/*AdapterV2.testkit.ts	makeReplayServerConfig now requires Scope.Scope and creates its base directory with makeTempDirectoryScoped. The adapter replay testkits also use the scoped operation. The test checks that stateDir exists while the scope is open and that baseDir is removed after it closes.

Exercise cleanup through the replay service.

This test calls each configuration factory directly. It does not check whether the replay layer keeps the directory available for the service’s lifetime and removes it when that layer closes. Test that lifecycle through the replay service so the assertion covers the scenario path.

As per path instructions, “For tests, exercise behavior through the service and use test layers only for external dependencies; do not mock the logic under test.”

Verified in a real dev environment

verified unchanged head 3fa7145f7c9234f331349d75b18aca099711cfb6 on linux against github/main at 5732bbee397f0a2b0e61d0c2e432f01dca6df3dc.

this is test-only code with no production client route. i verified its actual replay lifecycle separately from the real app smoke checks:

• main: five adapter suites passed (447 tests), leaving 117 shared replay directories. the three acp registry/grok/fx replay integration suites passed (40 tests), leaving another 80 directories: 40 shared, 15 acp registry, 16 grok, 9 fx.
• pr: the same eight suites plus the cleanup test passed (9 files, 483 tests). a fresh TMPDIR contained zero t3-orchestration-v2-* directories after the processes exited. the cleanup test also checks that state exists inside the scope and disappears after it closes.
• all checks ran through blacksmith-check, with dependencies installed inside each worker. vp run check:changed passed format, lint, knip, graphql, typecheck and focused tests.
• started main and pr dev servers sequentially with isolated state. created a project pointing at a real git repository through the running server and ran real codex gpt-6.1-sol turns on both. both returned the working directory and confirmed the git repository.
• used the repository's playwright dependency with google chrome to submit a follow-up through the pr web composer. codex ran git rev-parse --short HEAD and returned 3fa7145f7c. reloading preserved both replies. app data used no mocks or seeded fixtures.

Not verified

native desktop, ios/android, macos/windows cleanup, real claude/grok/fx/acp agents, and the full repository suite. the changed test helpers are unreachable from ordinary app turns, so the codex recording proves neighboring app behavior; replay checks prove the cleanup itself.

no source changes or pushes were needed.
