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).
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.
The Windows coverage lane grants DSH_COVERAGE_TEST_TIMEOUT_MS=90000, but two
paths declined it.
scripts/install-lefthook.spec.ts took a describe-level 30_000, restated as a
per-case constant on five cases. Every case drives spawned Git and Node
subprocesses; the slowest costs 7.5 s on an idle host, so the ceiling carried
roughly fourfold headroom and fired on branches that did not touch the file.
The suite takes 90_000 and the redundant constant is removed.
coverageTestTimeoutArgs raised --testTimeout and --expect.poll.timeout but left
--hookTimeout at Vitest's separate 10 s default, which removeFixtureSafely's
documented 10-second Windows retry window meets exactly. Raising only the test
budget would move a contended suite's failure into its teardown.
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.
