* build(deps): remove npm shrinkwrap; mirror pnpm lock into transient package locks
npm 12 removed shrinkwrap (command + tarball/root loading). Delete all 82
committed npm-shrinkwrap.json files and stop publishing lockfiles; keep
pnpm-lock.yaml as the single reviewed dependency boundary. The generator
becomes scripts/generate-npm-package-lock.mjs and feeds plugin bundling via
a transient package-lock.json + npm ci (works on npm 11 and 12). Tarball
validation treats the published 2026.7.2 beta train as a shrinkwrap
transition; self-update npm detection now uses install topology instead of
the shipped shrinkwrap.
* fix(deps): repair lint, deadcode, and test-type lanes for the npm 12 migration
- sort integrity comparisons with an explicit comparator (oxlint)
- keep resolveBunGlobalNodeModules module-local (knip unused-export gate)
- model npm pack --json as npm<=11 array / npm 12 name-keyed object
- default calver destructuring in the tarball test fixture
The installation hit Blacksmith's backing-disk cap because sticky keys
embedded PR numbers and content hashes, minting a new disk per PR and
per input change until every mount 429-failed fleet-wide. node-deps
(#109752) and ext-boundary (#109804) were already re-keyed; this
converts the last two minters and audits the third suspect.
Keys changed:
- Vitest fs transform cache: `vitest-fs-v2-<pr-N|protected>-...` ->
the one existing `vitest-fs-v2-protected-<os>-<arch>-node-<ver>`
disk. Entries are content-hash keyed (vitest sha1 over
id+content+NODE_ENV+version+env config), so cross-PR sharing is safe
by construction: PRs now mount the protected snapshot directly
(read-only, commit false) and the separate PR-only seed mount is
deleted. Writers (non-PR shard writer + scheduled warm run) keep
explicit commit true. Disk count: 1 + O(open PRs) -> 1.
- Gradle: `gradle-v1-<task>-<pr-N|protected>-<hashFiles(deps)>` ->
`gradle-v2-<task>`. Task scope stays (light ktlint must not seed
heavy build lanes); PR number and dependency hash leave the key. The
dependency hash moved to an in-job fingerprint marker that makes the
non-PR writer rebuild its snapshot cold when inputs change, bounding
disk growth; PR mounts are read-only and safely reuse stale
snapshots because Gradle caches are content-addressed. Disk count:
O(tasks x PRs x dependency bumps) -> O(tasks) (7 today).
- Docker builder (useblacksmith/setup-docker-builder): audited, out of
scope. The action owns its key internally and always uses the repo
name only (src/setup_builder.ts getStickyDisk), so it is already one
disk per installation repo and cannot mint per-PR disks.
PR warm-path behavior changes:
- Vitest: PRs lose only PR-local warm entries for files the PR itself
changed (previously persisted on the pr-N disk between pushes);
changed files re-transform once per push, unchanged files still hit
the protected snapshot. PRs touching transform inputs
(lockfile/tsconfig/package.json) run cold per push since the
generation wipe is now local to the discarded clone.
- Gradle: dependency-bump PRs get warmer (stale-but-valid protected
snapshot instead of a cold fresh key); other PRs are unchanged.
Deleted `.github/workflows/pr-cache-cleanup.yml`: it existed for the
per-PR cache layer (#109425) and only deleted GitHub actions/cache
archives, which GitHub's own LRU/TTL eviction already handles for the
remaining fork/Windows per-PR archive paths.
Guards: pinned the O(1) vitest key + non-PR commit gate, added a
Gradle per-task key/writer/fingerprint guard, added a repo-wide scan
asserting no useblacksmith/stickydisk key ever contains
github.event.pull_request.number or hashFiles(), and replaced the
cleanup-workflow assertions with a stays-deleted check.
* perf(ci): serve node_modules snapshots from O(1) protected sticky disks
Every Blacksmith mount of the dependency sticky disk currently 429s:
the v2 key minted one backing disk per PR and per manifest hash, which
saturated Blacksmith's installation-wide 1000-sticky-disk budget (run
29559333389, job checks-node-compact-small-15: "Sticky disk limit
exceeded"). Same-repo shards then fall back to a cold, storeless pnpm
install (~40s) on every run - worse than the ~22s actions/cache path
the sticky rollout replaced.
Re-key the snapshot to one stable disk per node-version and move the
install inputs into a runtime fingerprint marker:
- Key is now `<repo>-node-deps-bind-v3-<node-version>`; dependency
changes refresh the disk in place instead of allocating a new one.
- The fingerprint (manifest hashFiles set + node version + lockfile
mode) is evaluated on the bind step, before the mount lands, so the
'**/package.json' glob cannot sweep snapshot-internal manifests.
- Consumers mount read-only (commit: false); on fingerprint match they
restore importer archives and skip pnpm install entirely, on mismatch
they install against the clone's on-disk store (warm store, no
actions/cache download) without capturing.
- Writers are trusted non-PR jobs only: build-artifacts on canonical
pushes plus the scheduled vitest-cache-warm run as a deadline writer
(main pushes cancel each other under merge traffic and would starve
the snapshot). commit: on-change keeps warm no-op runs from
committing.
- Roll the consumer flag out to every Linux Blacksmith lane that
installs dependencies (build-artifacts, check-shard,
check-additional-shard, check-docs, checks-ui, control-ui-i18n,
native-i18n, qa-smoke-ci-profile, checks-fast-core, both contract
shards) with the same fork/dispatch gates as the nondist shard.
Guards now enumerate the consumer set, pin the O(1) key shape, enforce
single-writer commit expressions, and cover the fingerprint marker in
the importer capture/restore helper.
Verified locally: importer archive capture 0.96s/228K and restore
0.07s against the real 2.0GB hoisted tree; a snapshot untarred into a
fresh workspace resolves modules, runs bin shims, `pnpm exec`, and a
Vitest suite (one-time pnpm reconcile only when the absolute path
changes, which Blacksmith's fixed /home/runner/_work layout avoids).
* fix(ci): commit dependency snapshots explicitly, not via on-change heuristic
stickydisk's on-change mode compares allocated disk bytes with a 4KB
threshold, so a fingerprint refresh whose reinstall keeps usage stable
(metadata-only manifest edits, same-sized dependency swaps) could be
silently discarded, stranding every consumer on a stale marker and a
permanent reinstall path. Writers now commit explicitly, mirroring the
Vitest transform disk's rationale; warm no-op writer runs re-commit an
identical snapshot, which is cheap and safe. Also document that the
non-PR commit gate binds cooperating code only - the enforced trust
boundary stays the fork/dispatch runner gate, matching the protected
node-compile disk's posture.
* test(ci): guard sticky consumers against writerless node-version key splits
Reviewer follow-up: the snapshot key is partitioned by node-version and
both writers (build-artifacts, vitest-cache-warm) rely on the action
default, so a consumer pinning any other version would split onto a
key nobody seeds and silently regress to permanently cold installs.
Pin the action default to 24.x and assert every sticky consumer
resolves to that same key segment.
* test: narrow sticky-consumer step.with before indexing
The filter's runtime narrowing did not carry into the map callback, so
step.with indexing failed check-test-types (TS18048). Collect a narrowed
stepWith instead.
One-time maintainer-authorized bootstrap merge for the release-gate verifier policy. Exact hosted CI and all supporting workflow gates passed on 66133de419.
