The persistence seam is now create/open/stat/list returning per-session
SessionHandles (read/append/flush/close); every log read and write flows
through the owning handle. The seam package exports only the service and
handle contracts, consumer-visible errors, and pure durable-data
validation helpers; each backend owns its complete storage runtime, and
the shared contract suites pin equivalent observable behavior. The
backend routes published sessions' live events by id into the active
write handle; agent-loop only acquires, seeds, and closes the handle.
Resume appends interruptedTurnClosers through its write handle;
session-query owns the revision-keyed cold cache. Legacy-only surfaces
are removed in the same swap: locate/readRaw/supportsRawArtifacts, the
legacy event-shape read migration, zstd torn-frame salvage,
DSH_SESSION_JSONL, and hook transcript_path population; a torn final
zstd frame is discarded whole; the session-list cold blank probe returns
on stat metadata (eventCount derived from the last physical row,
sizeBytes). The WebUI ZIP export serializes the logical log from a read
handle, so both backends export identically.

New turnOutline projection unit serving every started turn's number,
turn/start seq, and bounded first-prompt preview through the
session-projection seam, mounted in the web-app bundle for the chat
turn rail. Entries stay strictly increasing; previews mirror the rail's
loaded-turn preview budget.
The CPython code runtime's complete public contract is experimental, so it
moves to packages/experimental per the experimental-packages rules: npm name
@deepseek-ai/dsh-experimental-code-runtime-python, private: true, no
publishConfig. All references updated (code-runtime READMEs, config-catalog
and module-graph regenerated with zh alignment, tsconfig paths, doc-standard
and workspace-constraints scripts, the fd-3 and settlement Agent Notes, and
the package README links); md-links and translation pairing pass, and the
suite still runs green.
The earlier merge had adopted master's protocol-only package.json (peer/dev
limited to invariants and cordis, no dependencies), but src/index.ts imports
@deepseek-ai/dsh-code-runtime, dsh-session, dsh-timeout, and schemastery at
runtime — a published lib/index.js could not resolve those bare specifiers.
The manifest now mirrors code-runtime-worker-thread (the five peers, the
schemastery dependency, and the matching dev set); the lockfile, module graph,
and third-party notices are regenerated, and the module-graph zh pair is
re-synced.
Land the PythonCodeRuntime implementation on top of the fd-3 protocol
seam: python3 -I per run, binding namespace over fd 3, RLIMIT_CPU/AS,
wall-clock timer, and SIGTERM->grace->SIGKILL process-group teardown,
with the real-subprocess integration suite.
Fixes three defects surfaced on the source PR's review before they ship:
- boot-write failure resolved a worker-exit through finish()/settle()
that read wallTimer/onAbort/live in their TDZ, rejecting run() instead;
the boot write now runs after those bindings and the v8-ignore that hid
the branch is removed.
- log capture serialized against settlement with no lock while model
daemon threads keep writing; LogBuffer now owns one shared re-entrant
lock taken by write/flush_line/push.
- the fd-3 line residual was a subarray view pinning the whole joined
frame; it is copied into a right-sized Buffer via detachResidual so
pendingBytes measures what is retained.
Reconciled with the scope-grouped plugin list: compositionInventory keeps
its additive block over master's RemoteError refactor; the slimmed
settings-store keeps ctx-based signatures while staying a display-only
roster store (no describeFace, no select); dead transport-rejection tests
dropped with the wire that no longer rejects; module graph, catalogs, and
harnesses regenerated against the merged tree.
The settings plugin list projected ctx.loader.entries() alone, hiding the
plugins sessions actually run and rendering the web overlay's deliberate
disabled tombstones (tool-bash, tool-fs, ...) as two dozen plainly disabled
rows while the same modules ran in every standard-preset session.
- dsh-agent-presets: compositionInventory() answers flattened rows per
preset — newest live standing generation when mounted, composition file
otherwise with !!js disabled gates evaluated against the Loader context;
reading never mounts (regression-tested), refusal stays 'conditional',
raced files report broken with the reason.
- dsh-host-plugin-inventory: list() gains an optional agentPresets block,
resolving the roster as an optional peer and mapping fiber states to the
public phase vocabulary.
- ui-settings-plugin-inventory: preset group first behind a display-only
switcher opening on the default preset; global group collapsed with
failures floated; host-disabled modules enabled by >=1 preset fold into a
session-plugins drawer naming providers; search spans scopes and points
at matches in unselected presets.
- ui-agent-preset: the General-settings default-preset row is deleted — the
roster section's make-default and the new-session chip keep the field —
and the settings store slims to the display roster the header label reads.
Docs, catalogs, module graph, settings-chrome goldens, and the bilingual
Agent Note ride along.
- gen-cordis-catalog / gen-cordis-inspect-catalog / gen-client-catalog /
gen-config-catalog / gen-doc-graphs / gen-module-graph outputs pick up
the converged Remote vocabulary (gateway/* codes, RemoteError JSDoc)
and the dsh-util-time package; the zh sides of the three
English-generated pages follow the same line-number shifts.
- the message-feedback protocol golden records the accepted wire
change: a boundary-validation failure now reports
gateway/input-invalid with structured details instead of a bare
internal code.
