ApiProxyDefaults uses an exact optional property, so passing config.sessionExportCompressionLevel directly made the service object carry an explicit undefined that is not assignable to the resolved request shape. The full host build caught this distinction after the redundant fallback was removed.\n\nConditionally omit the property when Cordis has not supplied a value. Direct createApiProxy callers still receive the implementation-owned default, while configured plugin values pass through without introducing another defaulting site.
Response-consumer cancellation already stopped lineage reads, persistence reads, and ZIP production, but the final attachment phase called readImage without the producer signal. A slow or stalled attachment backend could therefore keep working after the browser abandoned the download and prevent the producer from settling.\n\nExtend the attachment read seam with optional cancellation, forward it through the local backend into Node's filesystem read, and preserve the abort reason rather than wrapping it as a storage failure. The exporter now passes its combined request/consumer signal to every attachment read.\n\nCover both ownership boundaries: the local-store test proves filesystem forwarding and cancellation identity, while the assembled export test cancels a reader during a pending attachment provider call. Regenerate the Cordis API catalog and paired documentation so implementers can rely on the new contract.
The response stream uses a fixed 64 KiB byte high-water mark; no deployment setting controls it. Calling that queue configured incorrectly suggested another tuning surface and obscured the concrete memory bound.\n\nName the fixed capacity directly while preserving the separate bound of one synchronous fflate push beyond the queued bytes.
The pre-stream error boundary covers both the live-session flush barrier and the persistence read, but its response attributed every failure to reading storage. A flush failure therefore produced a misleading diagnostic even though the response correctly withheld private backend details.\n\nUse preparation as the shared operation name and cover the flush-failure path explicitly. Both preparation stages now retain one stable, path-safe HTTP 500 without pretending to identify the failing stage.
The Cordis schema supplies the normal plugin default, while createApiProxy also owns the fallback required by direct programmatic callers. Repeating the same nullish fallback in ApiProxyService created a third defaulting site without adding a distinct invariant.\n\nPass the validated config value through unchanged and leave createApiProxy as the single implementation boundary that turns an optional request value into the required compression specification.
Session-log ZIP entries always used DEFLATE level 6 even though compression level is a deployment tradeoff: CPU-constrained hosts may prefer low latency while bandwidth-constrained hosts may prefer smaller archives. A hardcoded level also violated the repository rule that deployment-varying plugin choices live in validated Config.
Add sessionExportCompressionLevel to ApiProxyService.Config as an integer 0-9 with default 6, resolve the same default once for direct createApiProxy callers, and pass the required level into the streaming module. Tests prove schema defaulting and rejection as well as a level-0 versus level-9 archive-size difference with identical extracted content. The generated config catalog, bilingual gateway README, and feature note document the knob and its tradeoff.
The ZIP loop checked desiredSize only after a push and responded to an overfull queue with setTimeout(0). A timer turn does not mean the consumer drained anything, so a slow or disconnected client still allowed the producer to enqueue the complete compressed archive while later artifact and attachment reads ran eagerly.
Give the ReadableStream a 64 KiB byte queuing strategy and block the single producer on a pull-released capacity gate whenever desiredSize is non-positive. Cancellation wakes that gate through the existing producer signal; synchronous fflate output is therefore bounded to the queue high-water mark plus one input push. A regression test exhausts timer turns without consuming and proves the next media entry remains unread until response pulling begins, and the bilingual contracts now describe the real bound.
Only the root raw-artifact read received the request signal. Lineage discovery and descendant reads could continue after disconnect, response-body cancellation did not stop the producer, and the root error boundary converted an abort rejection into an ordinary HTTP 500.
Combine request and response-consumer cancellation into the ZIP producer signal, forward it through every cancellable read, check it around the attachment seam, and terminate fflate exactly once when production stops. The pre-stream boundary now rethrows the original abort instead of translating it. Regression tests cover signal propagation, exact cancellation identity at the HTTP boundary, and a reader cancellation interrupting an in-flight descendant read; the bilingual host contract records these lifecycle semantics.
The exporter read persistence artifacts directly even when the requested root or a descendant was still live. Buffered session events could therefore be omitted from a successful download, so the advertised verbatim-artifact guarantee described storage accurately but captured an arbitrarily stale durability boundary.
Resolve each id against SessionStore and cross its authoritative flush barrier immediately before readRaw. Cold sessions remain a no-op, while live roots and descendants are made durable independently; this intentionally yields a per-session read-boundary snapshot rather than claiming an atomic lineage snapshot. A host-path regression test proves both artifacts change from stale to durable only through flush, and the bilingual host contract and Agent Note document the boundary.
SessionPersistence.readRaw previously used undefined for two unrelated states: a supported backend could not find the requested session, or the backend had no per-session artifact concept at all. The export endpoint consequently reported an existing SQLite-backed session as HTTP 404, which falsely diagnosed storage capability as session absence.
Make raw-artifact support an explicit backend capability. Unsupported backends now fail their inherited readRaw path loudly and the host answers 501 before reading, while undefined retains the single meaning of an absent artifact on a supporting backend. First-party backends, test providers, generated API catalogs, bilingual persistence docs, and export error contracts now state that distinction; focused tests cover both the 501 and the inherited rejection.
Only `docs/module-graph.*` conflicted; generated, so taken from master and
regenerated. `api-proxy.ts` auto-merged — this branch's history read
(`historySourceFor` / `presenterScopeFor` / `historyCutOf`, in that order)
is intact.
Hook bypassed as before: the staged-pairing check hands an archived note path
to `verify-translation-pairing`. The full-corpus gate passes.
The export ZIP now carries every image any included log references under
media/<attachmentId>.<ext>, read and verified from the attachment store with
one entry per shared image. The endpoint requires the attachments service
alongside persistence and session-query; a referenced image that cannot be
read fails the stream like a missing descendant.
Generated docs (`module-graph`, `event-producer-consumer`) taken from master
and regenerated. The `cordis-inspect-jsdoc` golden likewise: master's copy is
the base, and this branch's `presentAs` per-scope rewording is re-applied on
top, since `cordis_inspect` renders that JSDoc into model-visible output.
Hook bypassed as before: the staged-pairing check hands an archived note path
to `verify-translation-pairing`. The full-corpus gate passes.
Old runtimes meeting a newer session format now fail loud instead of
misreading: version refusal names the direction (newer: upgrade the
harness; older: no upgrade path) and points at the raw JSONL log, and an
event type outside the generated known vocabulary refuses resume unless
its envelope carries the new ignorable: true marker (default: required,
so a forgotten marker over-refuses instead of silently resuming a gutted
session). gen-persistence-catalog now also emits
KNOWN_SESSION_EVENT_TYPES; SQLite stores the marker in a dedicated
column (SCHEMA_VERSION 15). The versioning design (monotonic integer,
n->n+1 upgrader chain, migrate-on-continue) is recorded in the
session-log-version-mechanism Agent Note.
Master moved peerDependencies to `workspace:^`; this branch's two added peers
(`dsh-agent`, `dsh-system-prompt`) take the same form. `docs/module-graph.*`
is generated; regenerated after the merge.
Hook bypassed for the same reason as the previous merge: the staged-pairing
check hands an archived note path to `verify-translation-pairing`. The
full-corpus gate passes.
Review found two defects in the previous commit's ordering fix.
@pku-xht: `historyStateFor` copied the attached session's events, the handler
then awaited `presenterScopeFor`, and only then read the projection baseline
off the still-live Session. An append during that await served events cut at N
beside a baseline folded to N+1 — one response describing two moments. The
same restructure had also moved the baseline read outside the `try`, so a
failing snapshot escaped the structured `internal` error.
Both awaits now happen before the cut: `historySourceFor` resolves which
session serves the read, `presenterScopeFor` ensures the recorded composition,
and `historyCutOf` then reads events and baseline adjacently with nothing
between them. The whole sequence is back inside the try.
The invariant judged any scoped assembly with a chain of one as an unjoined
agent, which rejects a legitimate assembly in a standing preset key (that key
has no parent of its own). It now gates on `context.agent` — a scope-only read
is not an agent and is out of range by construction rather than by a premise
about who else calls `assemble` — and asks the roster's own
`composedPreset()` instead of introspecting chain length. The advisory warning
uses the same relation.
Also from review: the `2026-08-05-per-agent-tool-presentation` note still
described `presentAs` as per-agent, which standing mounts made false and this
branch's own rewording contradicts; the duplicated "process-wide unit table"
argument collapses to the Agent Note with pointers from the five copies; a
dead `.sort()` before `arrayContaining`; and change-history narration in the
tool-cordis README.
The pre-commit staged-pairing hook was bypassed for this merge: master's
`docs(notes): archive superseded dsh run decision` (7ee9e16001) arrives as a
rename into `.agents/notes/archived/`, and the hook hands that path to
`verify-translation-pairing`, which correctly refuses an archived note as
out-of-corpus. The full-corpus gate passes (851 pairs).
1504 hand-written ranges pointing at workspace members become workspace:^, so
pnpm pack substitutes each member's real version at publication: sibling
peerDependencies follow the family version instead of being pinned at ^0.0.1,
and a reference to a vendored package follows that package's own line. Without
this, publishing 0.0.2 ships peer ranges naming a version that does not exist,
and 0.0.1-rc.1 does not satisfy ^0.0.1 either.
It also retires ranges that had gone stale against the workspace: ^4.0.0-rc.6
for a 4.0.0-rc.7 checkout, ^3.17.0 for schemastery 3.18.0.
workspace:* stays where an exact published version is the point, which is how
the Landlock entry pins its platform packages.
A workspace constraint now requires the protocol, so a new package cannot
reintroduce a hand-written range. The same constraint caught packages/boot/cmdline
arriving on master without the publishable trio, which this change completes.
Every package under packages/, apps/, and vendor/ drops "private": true and
declares publishConfig.access "restricted": the repository now states which
packages it publishes instead of deciding it at publish time. Each one also
declares its repository and directory, which is how a consumer of a private
package reaches its source.
The Landlock packages move to restricted with them. They have never been
published, so nothing anonymous depends on them today, and the whole
@deepseek-ai scope stays private.
The workspace constraint that required every package to be private now applies
to non-members only, and asserts the publishable trio on each release member.
`minimal` was rewritten upstream into a fixed-prompt PTY surface that now
carries its own compaction group, so this branch's token-meter move applies to
it too: the row leaves the group and `tokenMeter` leaves the realm, exactly as
in the other three presets. Master's header prose is kept whole — the note this
branch had added there described a composition that no longer exists.
`docs/event-producer-consumer.*` is generated; regenerated after the merge.
`session.history` built its projection baseline in `historyStateFor` and only
then awaited `presenterScopeFor`, which is what ensures the recorded preset's
standing mount. The unit table is process-wide while the units themselves are
registered by preset rows, so on a first cold read the baseline was serialized
before `todos` (and every other preset-owned key) existed, and every later read
served a complete one. Until this branch, a web lane happened to mount a preset
in `beforeAll` for unrelated reasons, which hid the ordering.
The baseline is now a thunk the handler reads after the scope resolves. Also
covers the roster-less early return of the unjoined-agent warning, which the
per-file coverage gate reported uncovered.
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.
The persistence subsystem page gains the SessionRawArtifact section (with a
type-equiv manifest entry and zh counterpart), and the README and Agent Note
describe the drain-based backpressure instead of claiming the archive never
accumulates.
Chunk boundaries never split a surrogate pair (a lone high surrogate
re-encodes as U+FFFD and silently corrupts the exported artifact), production
yields whenever the response queue fills so a slow consumer bounds the
accumulation, includeDescendants rejects values other than true/false instead
of silently under-exporting, the dead missing-services arm is deleted by
narrowing the streaming deps, and the readRaw failure answers 500 without
leaking host paths into the browser error bar.
`session.create` also adopts an already-live session, and the preceding
commit newly allows adopting one under the preset it switched to while
blank. Its response still echoed `header.agentPreset`, so that adoption
answered with the preset the session had just left — contradicting the
request it had accepted and the row `session.list` serves for the same
session from `resolveSessionPreset()`. The echo now resolves the same way.
The `assertPresetUnchanged` parameter doc said `existing` was the preset
the session was created under; both callers now pass what it runs.
`composeFrom()` was documented as "infallible" and "cannot fail" beside two
`@throws`. It has no composition failure mode — no roster read, no mount, no
file — but it does reject a caller error, and the wording now says which.
The package-level "switched preset" test re-linked to the same preset id,
so it could not tell reading the parent's live scope chain from reading its
creation header. A second fixture preset makes the switch real.
The Web browser lane's subagent goldens gain the preset badge a child now
shows, which is the visible consequence of recording its composition. That
lane runs only under DSH_EXAMPLE_MODE=lib and was missed before.
The Agent Note records two limits found in review: a cold-resumed
continuable child joins its parent's current composition rather than the one
its header names, and `toolFilter` does not constrain a joined child. The
latter is a regression from the agent-plane move rather than anything this
change introduces — with the same tools in the global layer the filter
applies normally — and is tracked in #2185.
Refs #2185
Streams one ZIP of the root session artifact plus each subagent descendant
verbatim (the persistence readRaw bytes) from GET /api/session.export as a
host-only download — no wire envelope, absent from IApiClient. The downloads
domain owns the query schema, the fetch handler answers the GET alongside the
SSE routes, and compression runs on the host with fflate's streaming Zip API.
Tool and prompt-section visibility is inherited along dsh-scope's parent
chain, and an agent's scope key is minted with no parent. Per-session agent
presets moved every model-facing row onto the agent plane and made
AgentPresets.mount() the one thing that binds that link, from the api-proxy's
session create, resume, and fork paths. The two in-process subagent drivers
installed only the per-child persona and tool filter, so a child's scope chain
had length one and its registry view resolved the global layer alone — which
is empty wherever a preset roster is composed. One-shot children reached the
model with no tools, continuable ones with only the host-plane `report`, and
neither carried its parent's persona, workspace context, or skill catalog.
AgentPresets.composeFrom() joins one agent to the standing composition another
already runs on. It is a bind, not a mount: the child gets its parent's exact
generation, so a composition edited since the parent started cannot fork it
onto another one, and it is synchronous, which is what lets a child creation
window use it. applyChildComposition() now takes the parent and performs the
join first, making a child composed without it unrepresentable at the call
sites. childSessionMeta() records the joined id so a cold read rebuilds the
composition the child actually ran under.
The audit that followed found two api-proxy readers on the wrong authority:
presenterScopeFor() and the live-agent branch of assertPresetUnchanged() both
read header.agentPreset, which goes stale the moment a blank session switches
preset. A switched session's cold transcript resolved presenters in the older
composition's layer and silently degraded to generic cards, and the gateway
refused to adopt a live session under the preset it actually runs while
accepting the one it left. Both now resolve through resolveSessionPreset(),
matching the resume branch fifteen lines above. The owning architecture Agent
Note carried the stale claim that the header records what a session runs; it
is corrected to name the header/log pair and its three readers.
Fixes#2165
