The persistence seam is now create/open/stat/list returning per-session
SessionHandles (read/append/flush/close); every log read and write flows
through the owning handle. The seam package exports only the service and
handle contracts, consumer-visible errors, and pure durable-data
validation helpers; each backend owns its complete storage runtime, and
the shared contract suites pin equivalent observable behavior. The
backend routes published sessions' live events by id into the active
write handle; agent-loop only acquires, seeds, and closes the handle.
Resume appends interruptedTurnClosers through its write handle;
session-query owns the revision-keyed cold cache. Legacy-only surfaces
are removed in the same swap: locate/readRaw/supportsRawArtifacts, the
legacy event-shape read migration, zstd torn-frame salvage,
DSH_SESSION_JSONL, and hook transcript_path population; a torn final
zstd frame is discarded whole; the session-list cold blank probe returns
on stat metadata (eventCount derived from the last physical row,
sizeBytes). The WebUI ZIP export serializes the logical log from a read
handle, so both backends export identically.

The per-case 15-30s budgets on the Windows native and coverage lanes fire
before oxlint, workflow-worker-thread, and other subprocess-spawning cases
finish under the loaded self-hosted pool; the failures rotate across cases
as load shifts, so per-case widening only moved the flake. Raise the lane
defaults (DSH_COVERAGE_TEST_TIMEOUT_MS and the native --testTimeout) to 90s,
align the oxlint and workflow-worker-thread case budgets, and keep the
built-bin SPAWN_TIMEOUT_MS at 60s under a 90s outer budget.
Local run of check:ci:windows-complete (the windows-native gate) on
latest master surfaced five Windows-only failures, all unreachable by
current CI because the native windows job is disabled and the wine gate
only covers build+site.
- install-lefthook/translation-pairing-merge specs junctioned the real
scripts/ and tsx package into fixtures; Windows recursive deletion
(Node rmSync and git worktree remove) follows MOUNT_POINT junctions and
deleted the repository's own directories mid-run. Fixtures now unlink
their reparse points before any recursive removal (shared helper in
scripts/test-fixture-cleanup.ts).
- workflow-workerthread spawned its worker with an empty env; on Windows
os.tmpdir() then degrades to the literal relative path undefined\temp,
so tsx wrote its transform cache into a cwd-relative undefined/
directory inside the repo. The worker env now injects the host temp
path on win32 (workerSpawnEnv, platform-parameterized and unit-tested
on both arms).
- workspace-context spec did not stub USERPROFILE (win32 homedir) or a
set DSH_HOME, leaking the developer machine's real ~/.dsh/AGENTS.md
into discovery.
- ui-trajectory client-bundle spec mounted the built artifact without the
remote/settingsScope provides the locale plugin needs, so the plugin
never activated and no view registered.
- subagent temp-fixture cleanup lacked the maxRetries Windows handle
release needs under load (EPERM); added retries to the three affected
specs and the fixture-cleanup helper.
