754b8dd76c fix: make the installer runtime pass strict supply-chain vetting (#2503)
* fix: make the installer runtime pass strict supply-chain vetting

Remediate the four enterprise supply-chain vetting blockers from
affaan-m/ECC#2502 so the installer runtime (package.json + manifests +
scripts/lib/**) passes strict exact-pin evidence policy:

1. Remove the package.json `postinstall` lifecycle script (it only echoed a
   post-install banner) and move that banner to an explicit opt-in
   `npm run welcome` command. No install-time lifecycle script remains.
2. Exact-pin every dependency in package.json (dependencies + devDependencies)
   to the versions already resolved in package-lock.json; no ^/~ ranges.
3. Replace non-ASCII characters on the installer runtime script/config surface:
   em-dashes (U+2014) in scripts/lib/{path-safety,install-executor,
   install/link-rewrite}.js comments and the two "Itô" (U+00F4) occurrences in
   manifests/{install-components,install-modules}.json descriptions become
   ASCII, so strict-surface Unicode scanners are clean.
4. Drop the bare `require("ajv")` from scripts/lib/install-state.js; the file
   already carries a complete hand-rolled validator enforcing the same
   schemas/install-state.schema.json (ecc.install.v1) constraints, so the
   installer closure is dependency-free (zero non-builtin bare requires).

* fix: preserve tsc/pyright exit status in verification-loop type-check (set -o pipefail)

* chore(deps): sync lockfiles with exact-pinned package.json

Regenerate package-lock.json and yarn.lock so the pinned dependency
specs are reflected in both lockfiles. npm ci and Yarn's --immutable
install now pass the sync check. The resolution tree is unchanged
(231 yarn resolutions, byte-identical set; zero npm transitive drift);
only the root descriptor strings move from ranges to the versions
already resolved in the committed lockfiles.

Addresses the Codex P1 on #2503.

Parallel Execution Optimizer

Use this skill when speed comes from doing independent work at the same time: repo inspection, file reads, API checks, browser checks, build/test lanes, deploy readbacks, or multi-worktree implementation passes.

Core Pattern

Turn urgency into a dependency graph before acting.

  1. Define the objective and done signal.
  2. Split work into lanes.
  3. Mark each lane as parallel, sequential, or gated.
  4. Run independent reads/checks together.
  5. Keep writes isolated by file, worktree, branch, service, or dataset.
  6. Merge only after evidence shows the lanes are compatible.
  7. End with a verification table, not a vague speed claim.

Lane Matrix

Before a large push, write a compact matrix:

Lane | Can run in parallel? | Write surface | Risk | Verification
Repo scan | yes | none | low | rg/git status outputs
Backend patch | maybe | src/api | medium | unit tests
Frontend patch | maybe | app/components | medium | browser screenshot
Deploy readback | after build | remote service | high | live URL + logs

Only run lanes in parallel when their write surfaces do not collide.

Execution Rules

  • Batch file reads, searches, status checks, and metadata queries.
  • Use isolated worktrees for large unrelated implementation lanes.
  • Start long-running tests, builds, backfills, and deploys in separate sessions, then poll them deliberately.
  • If a lane discovers a blocker that changes the plan, pause dependent lanes and update the matrix.
  • Never let a background process outlive the turn unless the user explicitly asked for a continuing service.
  • Do not parallelize destructive commands, migrations, writes to the same table, or live customer-impacting deploys without an explicit gate.

Output Shape

Use this when reporting:

Parallel execution result:
- Lanes run: 5
- Lanes completed: 4
- Blocked lane: deploy readback, waiting on DNS propagation
- Fast path found: batched repo scan + focused tests
- Verification: lint pass, unit pass, live smoke pass

Failure Modes

  • More concurrency that creates conflicting edits.
  • Benchmarking the tool instead of the task.
  • Treating "fast" as done before correctness is proven.
  • Forgetting to poll running sessions.
  • Hiding skipped checks behind a success summary.
