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).
The local PTY readiness poll held its inferred_idle fallback for exactly
one pollIntervalMs after a prompt marker, so a bash foreground handoff
that lands on the silence boundary only wins the exact stdin_read
attribution when the kernel publishes it inside that single poll. On a
slow or loaded host it does not, and the attribution flips.
handoffGraceMs replaces the hardcoded one-poll window as a validated,
deployment-owned config field defaulting to 500ms, rejected at load when
it cannot contain one readiness poll. Real-shell tests that interrupt a
send now assert the session is usable again rather than which readiness
tier observed the handoff, because no fixed grace removes the race.
`config.maxWallMs` is only checked for positivity, and it is handed to
`setTimeout`, which clamps any delay above 2^31-1 ms to 1 ms. A deployment
configuring a 25-day wall ceiling therefore gets the opposite of what it asked
for: every run times out on the first tick. The runtime now range-checks the
field at load against MAX_TIMER_DELAY_MS from dsh-timeout and throws, so the
misconfiguration fails loud where it is self-contained instead of silently
inverting the budget.
`computeMs` needs no matching bound: it is compared against measured event-loop
utilization rather than fed to a timer.
The test asserts both the rejection and that the boundary value itself loads.
Review fix (ds-review-bot on #623): the READMEs and JSDoc still stated the
pre-baseline formulas — resolve() outranking 'the session's last
sandbox/mode event', 'effective = explicit grant ?? fold(events) ??
deployment default', and the approval README's 'last approval/policy event'
opener — which contradict the shipped semantics for a delegated fork whose
seed tail differs from its header baseline. Every statement now names the
override chain (own post-seed switches ?? inherited header baseline): both
READMEs (both languages), resolve()'s JSDoc, the session-mode module and
event-declaration docs, the raw folds re-scoped as building blocks, and
the regenerated catalogs.
