The live-link E2E intentionally creates a project without a lockfile. Prevent ambient CI=true from making Yarn 4's first install immutable, while preserving the CI environment for every other behavior under test.
The paragraph claimed later child output reaches only the scrollback. Output
after a settle still reaches the scrollback and whichever send is active when
it arrives — appendOutput writes both (session.ts:302-307), and settleActive
clears `active` rather than suppressing delivery. Only the settled operation
stops receiving it, which is what the timing bound protects.
Keep restore-only and self-hosted stores outside pnpm/action-setup's replaceable install directory, resolving the configured path for every paired cache. Pin Yarn 4 for the generated-project e2e so runner images without Corepack do not fall back to Yarn Classic, and update the bilingual decision record.
A cursor-less adoption (process restart + resume, fork, seam-module
reload) replayed the session's full log from seq 0, re-exporting
history that already left the process — a resume re-billed its entire
stored log on every restart, and a fork re-shipped the parent's prefix
under the child's id, doubling query-time counts on OTLP backends with
no native ingest dedupe.
dsh-session now exposes the fact the constructor already validated but
discarded: Session.firstLiveSeq, the constructor-seed length — the
first seq appended in this process. header.seedLength cannot serve
here: it is the durable fork-lineage boundary, and a resumed session's
constructor seed is its full stored log while the header keeps the
original fork value (llm-replay and session-query-sqlite depend on
that meaning). Constructor seeds also never publish on the
session/event firehose, so adoption replaying them was inconsistent
with the system's own publication semantics.
Adoption's cursor-less fallback starts at firstLiveSeq; seed events
still feed the chunk projection, so mid-step continuations re-drop
after a resume. Fork streams are no longer self-contained: records now
carry session.seed_length (with the existing session.parent_id) so
receivers stitch the child's stream onto the parent's. Accepted cost,
consistent with at-most-once delivery and recorded in the revival
Agent Note: a resume no longer backfills records a previous process
failed to deliver — a deployment with that requirement needs the
deferred outbox, not replay.
Pinned red-first: seeded adoption exports nothing (assertion reversed
from the prior seed-readback test, obsolete behavior changed with its
test), resume-shaped seed rebuilds the projection without exporting,
and fork records carry the stitch attributes.
- subagent-sdk: the default registry name becomes `dsh-sdk` (the bare
`sdk` read ambiguously in configs); READMEs, config catalog, fixture,
and suites follow. The Loader fixture now omits providerName to exercise
the shipped default end to end.
- loader-composition.e2e: two full harness runtimes boot in sequence, so
the default 30s loader-smoke window times out under host load; raise the
subprocess deadline to 120s with matching vitest headroom (the
real-model.e2e precedent).
master already stabilized the raw-mode SIGINT scenario in 65e0ffe03 and
3be090f1d with wider scenario-owned bounds and deliberately delayed child
readiness, so the merge takes master's test implementation. What this branch
keeps is the contract that explains why those bounds are required: the note
paragraph on the settle boundary in PtySendOperation.append, and the
waitForOutput comment recording that raising its deadline alone cannot
recover output the send never collected.
sha256sum-or-shasum selection happens in preflight (macOS ships shasum,
not GNU coreutils) with a clear missing-tool hint; provisioning now waits
for every child and reports each named status before exiting, so a fast
failure can neither hand the EXIT trap a scratch tree that a still-running
install is writing into nor bury the root cause behind a downstream
symptom.
- api: resolve a relative workspace cwd to absolute before the handshake —
the child spawns relative to the parent cwd, but the wire cwd is resolved
again inside the child, so a relative value double-resolved
(worker -> worker/worker).
- api: make the documented handshake retry real — HarnessClient.close() is
permanent, so a failed initialize now reaps the runtime and swaps in a
fresh client; DeepSeekHarness.close() is terminal and stops the respawns.
- api: validate session.event envelopes, assistant/message content, and
session.finished reasons at the wire boundary — a malformed runtime
surfaces as SdkProtocolError instead of type-invalid TurnResult data or a
TypeError out of finalResponse.
- client: a throwing subscribe() filter fails and detaches only its own
subscription (normalized to Error); sibling fan-out and the transport read
loop are undisturbed.
- client: NotificationSubscription.close() drops its queued notifications,
matching its documented contract; runtime-death fail() still leaves
already-delivered items drainable.
- client: subscribe() after close()/runtime death returns a born-failed
subscription so next() rejects instead of parking forever.
- client/transport: bounded requests abandon via AbortSignal — the transport
drops the pending entry at timeout, so repeated bounded calls against a
hung method retain no per-call state.
One test per finding; per-file coverage stays 100% on both packages.
