Review follow-ups: the Agent Note triplet moves to implemented/ rewritten as
shipped state (Decision/Consequences/Testing, present tense), cross-linked
both ways with the 2026-07-28 storage recovery proposal whose projcache
reset/destroy path it supersedes (that proposal stays live for authoritative
and whole-medium damage). The fixtures spec header and the note state the
fixture provenance as recorded facts of the released builds instead of
citing local tooling, and the spec JSDoc points at the note's final home.
The session_projcache domain declares compatibleVersions: [3, 4] and
invalidRecords: 'backup-and-skip'. The two lineage identity fields become
optional — records admitted from older versions predate them, and the single
reader (identityMatches) interprets absence as the unseeded lineage: exact
for unseeded sessions, while a seeded caller fails the match and refolds
cold, so the lineage binding keeps its protection. Upgraded homes therefore
boot and serve their cached listing titles immediately, including homes
whose new tree already holds current-stamped documents without lineage
fields, and a record failing validation anyway is backed up and skipped
instead of refusing the plugin tree.
tests/fixtures/ archives the real on-disk media of every shipped generation
(v3 whole-unit file, v4 and v5 per-record documents, and the lineage-less
current-stamped shape); fixtures.spec.ts proves each recovers through the
real storage stack, rewrites to the current format on the next live write,
and that a hopeless record is salvaged without costing the boot.
cache.spec.ts polled fire-and-forget fail-soft writes with a fixed 40ms
settle(); contended runners drain the write after the window, so the
warn/row assertions flaked. Poll the observable outcome with vi.waitFor
(5s) instead, matching the file's existing cold-read write-back pattern.
The sdk-client and subagent-dsh-sdk dispose-ladder tests passed tight
confirmation budgets (disposeGraceMs 100-300ms) to real children; on a
contended runner the SIGKILL exit edge can arrive after the budget and
close() misreports a slow reap as failure. Use the product-default
budgets (disposeGraceMs 3000ms) for the real-child cases; the fake-child
negative cases in dispose.spec.ts keep the 10ms bound.
The per-record rm in the cache spec hits an EPERM flake on windows
native (directory still draining); retry the recursive rm like the
subagent spec does. The unreadable-record probe is meaningless on
windows, where chmod 0o000 is a no-op; skip it there.
A session that never talks — a forked child seeded with its ancestor's
title, say — previously got its first cache row only at detach; a crash,
or a fork held live in the store, left the seed-derived values (the
title) unreadable on the cold list. Session creation is now a third
mandatory write point: the creation checkpoint folds the seed and
persists immediately. Write-policy docs (README + catalogs) updated.
A detached history read still traverses the complete log, but each unit's
fold is now seeded from its cached checkpoint: the registry's restore
slices off the already-folded prefix (events at or below the row's seq)
and applies only the tail. The first cold read writes the refreshed
checkpoint back (fail-soft), so the cache row is created on first read
and kept current afterwards. The recipe lives on the cache
(cachedCheckpoint, coldSnapshot, writeBack); the api-proxy carrier only
supplies the stored header and the full log.
cache.spec now boots the real storage stack (storage, storage-json,
storage-domain) and asserts the per-record medium directly:
<root>/session_projcache/sessions/<id>.json carries a version-stamped
{version, record} document, cachedSnapshot is synchronous (zero-I/O from
the domain's in-memory tables), and the write-policy / fail-soft / listing
coverage is preserved at 100%. json-backend.spec gains a per-record layout
block (per-record documents, overwrite/delete/reopen, unsafe keys and
undeclared tables rejecting, foreign-document discard on open, closed
guard, close drain, unreadable-as-absent); storage-domain domain.spec
covers layout validation and descriptorOf projection. list-children.spec
mounts the storage stack for its projectionCache cases and its
cachedSnapshot mocks and reads go synchronous; the api-proxy specs' cache
mocks go synchronous too. devDeps and tsconfig references updated for the
storage stack.
Store each session's projection_cache.json under the cache's own root tree
(<root>/<session-id>/projection_cache.json, wired to dshHomePath('projections')
in the base bundle) instead of beside the session log via
sessionPersistence.locate(). The cache owns its directory layout, keys
directories by the code-generated session id, and never consults the
persistence layer; the service now injects only sessionProjections and
sessions.
Drop the coldSnapshot method and its readFrom-tail fold ladder: every cold
consumer refolds from the log itself, so the cache only serves the listing
read (cachedSnapshot, one async file read per session) and the write side.
Fail-soft durability, per-path write serialization, in-flight drain, and
atomic 0600 writes are unchanged; the chain cleanup now observes its own
rejection so a failed write cannot surface as an unhandled error.
dsh-session-persistence leaves peer/dev dependencies and the tsconfig
reference; dsh-atomic-write moves to peerDependencies. Config gains a
required root.
- Write through @deepseek-ai/dsh-atomic-write with { mode: 0o600,
dirMode: 0o700 } instead of exporting a second atomic-write primitive
from dsh-storage-json; the session tree stays owner-only like the jsonl
backend's own directories.
- Serialize atomic replacements per cache path so an older cut can never
overwrite a newer one; track in-flight writes and drain them on
disposal so a late flush cannot land after teardown.
- Detect the absent per-session directory before the checkpoint cut and
durability flush: sqlite-style backends no-op the write entirely.
- Cold-read write-back path and identity both come from the stored log
header (tail.meta), so a stale caller header cannot mint an orphan
cache file.
- Add no-path coverage (write no-op, cachedSnapshot undefined, cold
fallback to the full-log rung) and a concurrent-write ordering test;
the package now holds 100% statement/branch/function/line coverage.
- Sync README.md/zh (inject list, coldSnapshot signature, per-session
file read wording), package description, the Agent Note alternatives,
and the superseded proposed/implemented notes (EN/ZH); add the
concurrent-checkpoint Known Limitation.
Replace the single global session_projcache domain with a per-session
cache file inside the session's own persistence directory, resolved
through sessionPersistence.locate(meta) — the persistence backend owns
the session-directory layout, the cache service keeps every checkpoint
and cold-read responsibility.
- cachedSnapshot(meta) becomes async (one file read per session);
coldSnapshot takes the session header so it can locate the file, with
the stored log header remaining the identity witness.
- Backends without a per-session directory (sqlite) disable the durable
cache: writes no-op and cold reads fall to the full-log rung. An
obsolete global cache is never read — derived data refolds on first
cold read (no migration).
- writeAtomic is exported from dsh-storage-json as the shared atomic
whole-file replace primitive; api-proxy listing and subagent cold
reads await the now-async cachedSnapshot.
- READMEs and a new Agent Note document the per-session medium.
Drop the persist?: boolean opt-in: every unit's state — client-visible and
host-only alike — is now written to the projection cache. A unit can no
longer silently skip the durable cache, host-only units no longer need an
explicit flag to participate in cold restore, and the persist-sharing
conflict check disappears with the field.
- ProjectionDefinition/ErasedDefinition lose persist; register overloads
simplify; checkpoint/restoreFloor/restore fold every registered unit.
- Registry and cache tests drop the persist:true fixtures and the
persistence-policy sharing test.
- READMEs and the state-and-client-views note record the uniform rule;
cordis API catalog and subsystem signatures regenerated.
Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it
prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`,
`verify-translation-pairing --write` for the touched bilingual pairs,
`gen-doc-graphs`, and one typert snapshot whose ids embed character offsets.
`pnpm run rescope-vendor --check` verifies the result.
Renames nine vendored packages (cordis, cosmokit, schemastery and the six
@cordisjs plugins) and every reference that resolves them: manifest names and
dependency keys, module specifiers including declare-module merges, cordis.yml
plugin names, tsconfig paths, every Markdown fence, and `docs/` prose.
Directory names, upstream versions, and dependency ranges are unchanged, so
vendor/README.md still reads as an upstream snapshot; its manifest table gains
an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed
at each fork's origin.
The tutorial tier follows the rename end to end: its yaml fences named plugins
the Loader can no longer resolve, its `ts ignore-check` fences disagreed with
the compiled fences beside them, and its prose quoted both. The contracts that
told readers to keep upstream names — the root convention and the vendoring
cookbook's tree comment and manifest invariant — now say to rescope instead.
Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle
purity gate now names the vendored libraries a browser bundle inlines, and the
files where a bare `cordis` is an agent-preset id keep that product data.
git mv the 12 packages from session-persistence/, session-projection/,
session-title/, and telemetry/ into one session/ group per the
regrouping RFC; merge the four group READMEs into one bilingual
triplet; rewrite the group segment in tsconfig references (intra-group
references shorten to ../<pkg>), tsconfig.base.json paths/globs,
knip.json keys, vitest include, gate scripts, and authored doc/note
citations; regenerate module graph, doc graphs, catalogs, and the
lockfile importer keys. No npm names change.
Full unit suite: 8779 passed; the 18 reported failures reproduce as
env flakes (ambient-proxy IPv6 tunneling, watched-dir inotify
timeouts under parallel load) — each passes in isolation with
NO_PROXY set, matching their known pre-existing behavior on master.
