Write handles now hold a durable lease (session.lock.json beside the
log): a random owner token, diagnostic pid, and an expiry. Acquisition
wins by exclusive create; a second process's create or write open rejects
while the record is unrenewed for less than leaseTtlMs (default 5 min),
and takes over after that — a crashed holder is waited out, never
reclaimed by pid. The holder renews every leaseRenewIntervalMs (default
4 min); a renewal that finds a foreign, vanished, or expired record — or
fails outright — marks the lease lost permanently, so every later
append/flush rejects with SessionOwnershipLostError while reads continue.
Close releases the record; read handles never touch it. Takeover of an
expired record is eventually exclusive: a replaced holder stops within
one renewal interval.

The dsh-family version rule lived only in the packages/ block of
checkWorkspaceManifest, so apps/ members and the root-named CLI carried the
shared version with no static check of their own. The name-based rule now
covers every scanned manifest; regression coverage names the stale-version
merge that shipped packages/util/http-proxy at 0.1.2-alpha.5 behind a
0.1.2-rc.1 family.
`session[.vN].jsonl` was assembled independently by the JSONL provider
(twice), the session-log export archive, and the recorded-session fixture
helpers. `dsh-session-format` now owns `sessionFormatLogFilename` and
`parseSessionFormatLogFilename`; the three consumers append only their
compression suffix, and the migration note names the owner.
`snapshotSessionFormatJson` re-implemented the lossless JSON walk that
`dsh-util-values` already publishes as `snapshotJsonValue` + `deepFreeze`,
and the frozen v0 relationship validator carried a third structural JSON
comparison next to `deepEqualJson`. Both now delegate; the format package
reports one `is not lossless JSON` diagnostic per labelled subject instead
of ten member-specific ones, and enumerable accessors whose values survive
a JSON round trip are accepted like `JSON.stringify` accepts them.
The continuable-child headless expectation and the Python `advanced` and
`restart` scenarios pin the current runtime, whose subagent children carry no
`session/end-seed` marker and whose assistant messages embed their streams:
the child fixture drops the marker and renumbers its references, `advanced/`
re-records `result.json`, and both scenarios gain their v2 Session fixtures.
Unit tests cover the `tool-call-delta` id and name validation, embedded
stream members without timing arrays, and the versionless-header refusal.
`session-log-export` names its archive entry after `SESSION_FORMAT_VERSION`,
a runtime value of the shared `dsh-session` instance, so `dsh-session` becomes
a peer dependency and the export is classified as peer-required in the package
dependency policy. The three Session format packages take the `0.1.2-rc.1`
root version that master now requires.
The repository-only benchmark, its unit-suite spec, the root script, and the
README section are removed; the accepted acceptance run's figures stay in the
embedded-assistant-streams note as recorded facts. The note also records why
the migration edge reuses the `dsh-llm` stream helpers instead of frozen
copies and why its target validation re-checks message/stream agreement
itself. A validation test that recomputed `RELEASED_V2_EVENT_TYPES` from the
same expression as its definition is dropped.
Spec files that create /tmp/dsh-* directories via mkdtemp now track and
delete them in afterEach/afterAll; module-scope fixture dirs (executor
spill dirs) are removed in afterAll. The file list came from the
observed-residue inventory on the self-hosted CI host: only specs whose
dirs actually accumulated were leak sources (issue #3134), superseding
the kept-but-unmerged CI sweep branch per the #3233 review decision.
Product per-process spill roots (dsh-subprocess-local spawn,
dsh-spill-local store) register a process-exit handler that removes the
memoized dir, so processes that used the spawn/spill path clean up on
normal exit. A SIGKILLed process cannot run in-process teardown; the
machine-side timer remains the backstop for that path.

Expose a live goals/get read plus goal/activation-changed for the Web strip, reject model resume of durable paused goals, refresh snapshot and generated documentation surfaces, and record the follow-up decision.
The new keyless sdk-spawn-node scenario drives the platform shell tool
through a command starting with node and requires the machine's own Node
version in the tool result with no PKG_EXECPATH in the child environment,
so a pkg upgrade that re-records the child-process patch cannot silently
restore the hijack. Runs on every target through --scenario all.
@yao-pkg/pkg's SEA bootstrap rewrites child_process commands named node --
including the string after a -c flag, exactly the Bash tool's bash -c form --
to the executable itself and stamps PKG_EXECPATH into every child
environment, so a model-issued 'node --version' silently booted the dsh CLI
instead of the machine's Node. Pin the packager as an exact root
devDependency invoked through pnpm exec and patch out the single
patchChildProcess call from the SEA bootstrap bundle; packaged children now
resolve node through PATH like any other process. The third-party notices
drop the build-time tools section: the packager is now a declared, patched
devDependency, so the manifest and patch tiers disclose it.
