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.
Refs #3245
Regenerates the module graph for tool-workflow's new dsh-jobs edge (the
doc-sync aggregate does not run that gate), refreshes the web lane's own
schema/prompt pins for the run_in_background tool text, re-packs every
session fixture the keyless refresh had left off the canonical packed
layout, covers pwsh-local's never-spawned empty observed readers, and
rewrites the pwsh-sandbox sync-rejection start() test to the seam's
actual containment contract — execute() never throws; the sync spawn
throw settles the handle killed and result() carries the attribution
split. That test sits behind the pwsh probe, so only the Windows lane
had ever executed it.
Reverting telemetry to its own transport dropped the package's dependency
on the proxy library, and the generated graph still recorded that edge.
The gate that catches this is `verify-module-graph`, which runs in
`check:ci:static` and not in `doc-sync`; the revert was checked with the
latter alone.
Master moved 212 commits. Conflicts were eight `package.json` and nine
`tsconfig.json` files, all dependency-and-reference unions: master dropped the
`runtime-diagnostics/invariants` reference across packages while this branch
added `util/http-proxy`. The lockfile, `tsconfig.base.json`, and the module
graph were regenerated rather than merged by hand.
Master also brought `verify-package-invariants`, which rejects an empty
invariant companion. This package's companion was empty by design, so it is
gone with its publication wiring — the export, the `files` entry, the project
reference, the `dsh-invariants` peer, and the test. Master did the same across
`util/`. The README carries the reason sentence that gate requires.
Carried in the same commit, because the review arrived while the merge was open:
`e2bApiUrl` moves out of the `dsh-e2b` entry into `src/api-url.ts`. Code Entropy
flagged it as a public name with no consumer outside its own package; the seam
keeps its URL-precedence test, which is worth having directly — getting that
order wrong hands a proxy the control-plane traffic and its API key.
Review asked why this is a plugin and why it exports so much. The design note
this branch shipped answered the second question itself — "a pure resolution
function plus an installation function" — and the code drifted to seventeen
exports and a Cordis plugin nobody approved or mounted.
The plugin is gone. Transport policy has one answer per process: nothing to
swap, and no scope narrower than the process to give one. Its `Config` was also
the only supplier of a configuration branch, so resolution now reads the
environment and nothing else — `mode`, the config-sourced fields, and the
`config` policy source were unreachable the moment the plugin left.
Four exports nothing outside the package used are internal again, and
`currentProxyPolicy` answers with the direct policy instead of `undefined`, so
`DIRECT_POLICY` no longer needs a public face. Nine functions remain, one per
way a caller can need the policy; two is not reachable with six consumer seams.
The package moves to `util/`. The note claimed a dependency on `undici`
disqualified it from that group; the charter governs harness dependencies, not
external ones, and the process note that says so predates this branch. The real
blocker was the harness dependency: resolution needed one method of
`LaunchEnvironmentSnapshot`, so it names a structural `EnvLookup` and the
launcher passes its snapshot unchanged. `net/` is dissolved.
Dropping the group's line from the repository layout also returns `AGENTS.md`
to its original ceiling, so the raise the merge needed is reverted.
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.
