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.
Add a benchmark lane (`vitest.bench.config.ts`, `pnpm run test:bench`,
gate mode `ci-bench`) and a required `node 24 / benchmarks` CI job that
runs it alone. Benchmarks synthesize their input in-process from fixed
parameters and fail on documented budgets:
- `open-generation.bench.ts`: a 200-turn released-v0 log with 500 text
and 125 reasoning deltas per reply (127,400 events, ~2.8 MB) encoded
through the frozen v0 codec; the migrating first `open()` must finish
within 2,000 ms in a child process capped at 128 MB of old space, and a
fresh process must open the published current generation within 500 ms.
- `conversation-fold.bench.client.ts`: 200 replies whose compact streams
hold 2,000 text + 500 reasoning deltas each, folded through every Chat
Definition by the real assembler; the fold must finish within 150 ms
and stay within 3x the fold of the same window with 100 deltas per
reply.
On this commit both gates fail: the migration exhausts the 128 MB heap
(4.8 s and 696 MB peak RSS without the cap; the pre-stack decode of the
same bytes took 34 ms and 168 MB) and the fold scales 11x with the delta
count. The stacked fixes bring both paths to O(records).
Archiving low-future-value Agent Notes (#3548) stripped the inbound
citations to three now-archived notes from the ui-primitives README, and
this branch rewrote the same "Controls and icons" opener so the new
component catalog owns the export enumeration. The resolution keeps this
branch's opener and drops the archived-note citation master removed, in
both languages; the pairing record is re-recorded from the merged pair.
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.
Client feature plugins never import one another's components, so
ui-primitives is their only channel for sharing one. Nothing told an
author to look there first, and the package offered nothing to look
at: its README named six source files against forty-plus exports.
Add Tag (read-only capsule badge, eight tones) and Switch (36x20
toggle with a required accessible name), extend StateDotState with
idle for a tracked subject with no activity, and move ui-agent-preset,
ui-settings-plugins, and ui-settings-plugin-inventory onto them.
The plugin inventory's conditional tag referenced
--dsw-alias-state-warning-primary, which does not exist, so both
themes had been painting its hardcoded #b45309 fallback.
State the reuse rule as the first step of the new-component checklist,
and give the README a component catalog so the rule has something to
check. The rule is guidance, not a gate: a package may still write its
own control, and the Agent Note records the five that stay local.
Three review follow-ups on the consolidated jobs seam.
The spill file a pull source keeps is job metadata now: the pump reports it
to the registry on every read (present or withdrawn), the projection lists
it under output.spillPaths, and the model's dropped-output notice names it
from there. Attached to a gap chunk it was lost whenever the ring itself
evicted (a pump that kept up never produced a gap) or whenever the gap chunk
was evicted later, and it could not follow a source that withdrew its file.
A job_output wait's claim on the settlement now carries a live flag that
the caller's abort clears synchronously from the abort event. The registry
rejects an aborted wait on a later microtask, so a settlement announced in
between used to find the claim counted and skip the notice the tool result
was not going to carry either.
The job-controller client entry and the tool-jobs entry stop exporting
implementation classes and render helpers nothing outside the packages
consumes; the client entry keeps IJobs, which also carries the ctx.jobs
Context augmentation to consumers.
The caller-bound operation set now says what it is: the jobs one caller
may operate on. The caller argument is required (SessionId | undefined),
so an anonymous view has to be requested explicitly instead of falling
out of a forgotten argument.
Clickable artifact links across the transcript (markdown anchors, prose
file mentions, web source/fetch links, produced-file chips, workflow
member links) now share one language: a dedicated --dsw-alias-link color
(light deepseek-500, dark deepseek-400) decoupled from
state-business-primary, font-weight 500, no underline at rest, and a
dotted 3px-offset underline on hover/focus. A new ui-primitives LinkIcon
leads each link with a currentColor category glyph (url / folder / code /
image / document / other) derived from the path extension by
classifyLinkPath. Produced-file chips drop the grey pill and 96px cap and
render at natural width, shrinking with ellipsis only on row overflow.
ToolRow's grey dotted file links and the grey show-in-folder action stay
as they were. The inline-code chip tint moves to neutral-50 (dark
neutral-800) with its 0.5px border kept.
Coverage: LinkIcon unit spec, refreshed markdown-dom fixtures, and the
clickable-links-gallery web e2e registered in the host compiler face.
Closes#3546
Stop re-exporting the verbatim file-store helpers from attachment-local, move
the raw-byte upload route handler into a non-entry module of file-upload, and
drop the redundant hook type re-exports from the Client entry. The route test
moves next to the module it exercises.
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.
Refs #3245
The settled-retention JSDoc, the required observed streams, and the session-controller type shifts changed what the config, persistence, Cordis, and event catalogs embed; CI's static and coverage lanes compared the stale copies. Regenerated, with the zh mirrors updated in step.
A rejected background spawn produces no process output, so the observed stderr reader the job registry pumps was empty and the model's job_output after such a failure showed only killed before exit, where master's consuming read rendered [stderr] followed by spawn failed: … with the cause. The local providers now serve the note as the whole observed stderr stream once the spawn rejected, and the consuming read still folds it in exactly once, so the model's first read after the failure is byte-identical to master's. ShellProcess.observed and both of its readers are required: every background process exposes offset readers, and the shell tools' pull sources no longer carry a no-readers branch.
The consuming shell read on master told the model where a truncated stream's complete text lived: [some output was dropped from memory; full output: <paths>]. The ring-backed read rendered a notice only for the ring's own eviction and ignored the gapBefore mark the pump puts on a chunk whose source lost bytes between two polls, so a fast producer's tail read as continuous output and no path survived. A lossy source read now carries the source's spillPath onto its gap chunk (JobSourceRead, JobAppendOptions, JobChunk), the pump forwards it, the ring retains it, and the model renderer emits master's notice for a producer-side gap or a ring eviction, listing the distinct spill files in offset order. The bash and pwsh sources already returned the subprocess reader's spillPath; the type now admits it.
Settlement trimmed the ring to settledRetainBytes before releasing waiters, so a job that finished before its first job_output handed the model only the last 16 KiB plus a dropped-output notice where master's consuming read kept the executor's whole tail. The ring now keeps every byte the model cursor has not consumed on top of the settled cap, and the first terminal model read trims to the cap.
The registered event was emitted after startPump, whose first drain runs synchronously and may announce output, so a source readable at once produced an output event for an id no subscriber had seen registered. The announcement now precedes the pump; the events JSDoc states that a job's first event is registered.
JobView.kind was typed as the merge-extensible JobKind, so the job-controller program, which compiles only the merges it can see, generated a strict codec of bash | subagent for job.rows and job.observe. The first pwsh, pty-send, or workflow job failed frame validation on both ends and the browser dropped the whole roster. The projection now carries kind as a string; JobSpec.kind keeps the Host-side JobKind. A built-artifact smoke parses a pty-send row through the generated schemas, and the seam spec pins the open type.
The `start` frame and the reconnect baseline attempt carried a wall-clock
`startedTime` that no Host or Client consumer read: the Host accumulator
and the Client reconciler copied it into their attempt maps and nothing
looked at it again. Presentation frames now carry only the coordinates
consumers use (attempt, revision, turn, step, chunk index, and v1 seq
provenance); the type-equivalence block, event graph, READMEs, and the
live-stream Agent Note follow the type.
