Preserve strict live-smoke challenges and structural system messages while adopting the native subprocess runtime. Regenerate only the current Cordis inspection recording from the upstream V2 source to retain its no-ordinary-PID coverage; predecessor bytes match master.
Observe actual shared-preparation waiter admission and settle both callers before cleanup, preserving current V3 migration expectations. Adopt master’s cross-platform teardown regressions without changing budgets or Session data.
Preserve the V3 PTC SDK assertion and enable the new human-steering runtime fixture while carrying master’s inbox lifecycle changes. Retain prior deterministic CI repairs and immutable predecessor ownership.
* feat(subagent): align continuable human inbox controls
* fix: repair rebase documentation and close test persistence
* docs: refresh rebased module dependency graph
Preserve system/message persistence while adopting named persona prefix/suffix and environment facts after reusable instructions. Resolve the Web assertion against the logged system message, not retired header.system. Keep the existing protected V3 integration PR as the root publication path; no rules are bypassed.
Consolidate the representation-change PR and its rebase reconciliations into one baseline. Preserve the exact tree and keep the in-history feature in the dependent PR. Follow-up fixes remain separate.
Session format v2 embeds each attempt's compact stream in
assistant/message and assistant/attempt, but Host and client consumers
still expanded it into per-member TimedStreamChunk arrays and did
per-member work; expandAssistantStream materializes the full array before
find/toReversed/break can answer. Session Stats (the projection phase of
every Session open), the token meter's usage and provider-assembly folds,
the subagent output fold, and the Session Controller image lookup still
paid O(members) allocation and time per settlement.
The Chat and Trajectory definitions were already settled from
message.content on master; the remaining per-member folds stay.
dsh-llm now exports record-level readers (first token, visible content,
visible text, last raw chunk of a type, raw chunks of a type, joined
text, run-aware assembly, per-run first-token/first-visible times) that
scan the compact records once with early exit. Session Stats reads
assistantStreamFirstTokenTime, the token meter reads
lastAssistantStreamChunk(stream, 'usage') and assembles through
assembleAssistantStream, the subagent output fold appends
joinAssistantStreamText, and the Session Controller scans
assistantStreamChunks(stream, 'block-end').
expandAssistantStream is deliberately not memoized: retaining expansions
costs roughly ten times the compact stream for the Session's lifetime.
It remains the validating path at durable boundaries.
Synthetic 200-turn v0 migration benchmark, median of five: first-open
projection 28.0 ms -> 5.4 ms, first-open total 76.9 -> 50.0 ms, peak RSS
137.2 -> 94.9 MB; reopen projection 17.8 -> 5.6 ms; all phase budgets and
the 128 MB heap constraint keep passing.
Run the dsh-archive-agent-notes audit over every active Agent Note on
current master, judging each record by whether its rationale still guides
work rather than by size or age.
- Archive 453 implemented bilingual triplets (417,882 English words):
completed UI chrome, narrow adapters, closed bug fixes, implementation
walkthroughs whose package READMEs, docs pages, generators, or successor
notes now carry the useful behavior, and 51 records fully superseded by
a later active note. Keep 201 implemented notes whose ownership rules,
negative guarantees, durable or wire semantics, security rules,
reintroduction conditions, or still-tempting rejected alternatives
remain useful.
- Reject 7 proposals whose premise is gone or whose work shipped in
amended form under other records; delete 2 rejected notes that no
longer prevent a plausible mistake.
- Retarget every remaining inbound link to the archived path, and repair
active prose that named an archived record as the owner of a live fact:
parenthetical citations drop, ownership sentences redirect to the
README, docs page, or active note that states the fact, and history
citations say so. Chinese files link the English archived path because
the pairing gate treats the frozen tree as outside the bilingual corpus.
- Seal 1,359 new frozen artifacts; existing seals are unchanged and
outbound links from archived notes are neither inspected nor repaired.
- Regenerate docs/config-catalog.md after the hook-bridge comment edits
shifted two source line numbers.
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.
