Small step before step 11, from the handover (#16).
Problem.
scripts/verify(ensure_js_dependencies) runsbun install --frozen-lockfileonly when one of a fewnode_modules/.bintools is missing. A checkout whosebun.lockchanged but whosenode_modulesalready exists keeps stale dependencies. This broke "build web app" once, after a dependency was added.Done when.
scripts/verifyreinstalls JS dependencies wheneverbun.lockdiffers from the one last installed, and still installs whennode_modulesis missing. It does nothing when both are unchanged. Proven by running it in a real checkout: fresh, unchanged, and after abun.lockchange. Added todocs/PLAN.mdas step 4b and merged todev.Class: mechanical → Luna max.

verify-deps, basebfa8af7ffcc146d0d87a14e8bdcf5ed8434eefa4(dev). Scope isscripts/verifyand the step table indocs/PLAN.md. I will verify Bun's own dependency marker behavior, implement lockfile freshness tracking, run the required fresh/unchanged/changed/final gates, and report the exact outputs.Finding/decision: Bun's official install docs describe
node_modules/.bun/as an isolated-install package store and say reuse is based on installed packagename/version; they do not document a project-local marker recording the lockfile from the last successful install.bun pm hashcomputes a lockfile hash, but it is not an install-success record. I am using a repo-local SHA-256 record atnode_modules/.infraternal-bun-lock-hash, written only afterbun install --frozen-lockfilesucceeds.

Result: no blocks-merge findings.
Finding 1 — later: workspace-local dependencies are not freshness-checked when the root marker matches.
Evidence:
Output:
The marker matched the lock hash and all six required .bin paths still existed, so the function did not reinstall even though a workspace dependency was absent. Running the real gate with the same state then produced:
The full gate caught this used-package failure, so this is later rather than blocks-merge for this change. A stale but still executable wrong-version package, or an unused stale package, can still evade the six-path check. The new comment's broad claim that the hash prevents “stale modules” is therefore stronger than the implementation; it should be narrowed if the code remains intentionally scoped to lockfile changes and required tools.
Reproduction results for the claimed cases:
Fresh install: after moving the existing root node_modules aside,

The merge also includesc035b0c, the job-tooling fix that makes Codex jobs show asCodex <Model> <Effort> [job]in comm and in the unit description, not only in argv[0].review-4b, Luna max): no blocks-merge findings.packages/*/node_modules/<dep>. The next step, "build web app", fails loudly in that case, and abun.lockchange or a missing required tool still triggers a reinstall. No further change.

Orchestrator: follow-up to step 4b.
scripts/previewhas its own copy of the old dependency check: it installs only whenviteorplaywrightis missing. After step 12d added@fontsource-variable/spline-sans-mono, the preview build failed withENOENT … spline-sans-mono/wght.css. It is unblocked by hand for now (bun install --frozen-lockfilein the preview worktree; the preview runs7bda001). Fix: havescripts/previewreuse the lockfile-hash logic fromscripts/verify(one shared helper, not a second copy). Queued as a small mechanical job.Pointer from ops-deploy: this job also addresses #17 by moving the lockfile hash and required-package checks into one shared helper used by
scripts/verify,scripts/preview, andscripts/deploy-o2.Finding:
scripts/previewchecked only whetherviteandplaywrightwere executable; it never comparedbun.lockto the install marker used by verification. The shared helper now checks the lock hash and required executables, andbash scripts/tests/js-dependencies.shpassed checks for first install, unchanged reuse, lockfile change, missing package binary, and failed install leaving the old marker intact.Pointer: the #17 stale-dependency fix is included in
