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).
@yao-pkg/pkg's SEA bootstrap rewrites child_process commands named node --
including the string after a -c flag, exactly the Bash tool's bash -c form --
to the executable itself and stamps PKG_EXECPATH into every child
environment, so a model-issued 'node --version' silently booted the dsh CLI
instead of the machine's Node. Pin the packager as an exact root
devDependency invoked through pnpm exec and patch out the single
patchChildProcess call from the SEA bootstrap bundle; packaged children now
resolve node through PATH like any other process. The third-party notices
drop the build-time tools section: the packager is now a declared, patched
devDependency, so the manifest and patch tiers disclose it.
Node's built-in fetch ignores HTTP_PROXY, so every harness request connected
directly regardless of what the user exported. Resolve one policy from the
launch environment and install it as undici's global dispatcher, then wire the
four surfaces a global dispatcher cannot reach: web_fetch's pinned transport,
the OTLP exporter's node:http agent, the E2B SDK's own proxy option, and the
environment a child process or worker thread is given.
Each outbound call site carries an egress test that drives its real code path
through a fake proxy; that measurement is what found the OTLP and E2B gaps.
Rename the tool-presentation transport from code-mode to ptc everywhere
that is not written into session logs: the mode config value becomes 'ptc',
the preset directory/id becomes ptc, the demo becomes demo:ptc, the
dispatch waterfall becomes tools/ptc-dispatch-log (types PtcDispatch*), the
prompt rule becomes tools:ptc-only, source/test files become ptc.ts etc.,
and prose says PTC mode / PTC 模式. The session-persistent vocabulary
(durable events tool/code-dispatch*, logged plugin name tools-code-mode,
sub-call id segment :code:) intentionally stays and moves in the stacked
persistence PR, which is blocked until the SESSION_FORMAT_VERSION v0→v1
migration lands with it. run_code, its code parameter, CodeSdkLanguage,
CodeRunFailedError, the dsh-code-runtime family, third-party codex names,
and frozen archived notes keep their names.
tsconfig.base.json resolved @deepseek-ai/dsh-* through 49 candidate
globs and @deepseek-ai/dsh-*/invariant through 45, one per package
group. Resolution tries candidates in order, so a package late in the
list paid for every earlier miss — and under the dsh source launch each
miss is an ERR_MODULE_NOT_FOUND that Node decorates with a full
CommonJS resolution walk. A boot profile attributed 934.6 ms, 35% of
startup, to that decoration path across 60,942 failed resolutions. The
cost landed hardest on packages/util/*, which sits at position 44 of 49
and holds the leaf utilities nearly every plugin imports.
gen-tsconfig-paths writes one explicit alias per package into a marked
region and both group wildcards are gone; verify-tsconfig-paths reports
drift and runs in the ci-static lane. Booting the headless profile from
source drops from ~2,157 ms to ~1,055 ms with --help output unchanged.
All 1,022 dsh specifiers in repository sources resolve to the same
target as before, except seven /invariant specifiers in the lsp,
terminal, and runtime-diagnostics groups that the deleted wildcard
never listed: those reached built lib/types instead of src, against the
rule that static gates resolve through paths to src on a clean tree.
Add verify-application-entrypoints to the top-level gate graph. It inventories executable sources and package bins across apps, packages, and examples; rejects unclassified launchers including root-level js/mjs/cjs/ts files; and permits only the dsh CLI plus the explicitly private Python runtime carrier exception.
Update repository, architecture, CLI, and naming records to state the same rule: Node consumers select a dsh profile instead of invoking application-package bins, and no compatibility aliases remain. Fixtures prove both allowed classifications and representative escape attempts, making the architectural rule mechanically enforceable.
