- New scripts/work/bump-updated-timestamps.mjs stamps the `updated:`
frontmatter field to the current ISO 8601 UTC timestamp on every
staged docs/work/**/*.md file. Idempotent; adds the field after
`created:` if missing.
- .husky/pre-commit invokes the bump script as step 2 (before
rebuild-state) so _state.json sees the fresh timestamp.
- Backfill all existing work docs (4 PRDs + 3 epics + 21 stories):
* created: promoted from \`YYYY-MM-DD\` -> ISO timestamp using
git log --diff-filter=A on each file (first-commit date for
stories that had no \`created:\` line, midnight UTC for PRDs
and epics that had date-only created).
* updated: added from \`git log -1 --format=%aI\` on each file
(last-commit timestamp); will be re-stamped to "now" by the
pre-commit hook on this commit.
Stories that had no \`created:\` line now get one.

## Goal
|
|
|
|
Implement a four-layer enforcement stack — Claude hook, skill, pre-commit hook, sandcastle reviewer prompt — that makes every new runtime dependency in a feature- or core-tier package produce a permanent **library trace** at `docs/library-decisions/<YYYY-MM-DD>-<package-name>.md`. Rejection traces are first-class records. Codifies ADR-022.
|
|
|
|
## Why
|
|
|
|
The repo's narrow third-party surface is uncodified. New dependencies enter via `pnpm add` with no checkpoint. Three signals exposed the gap: a near-miss adding a build-time-only library, post-hoc ADR records (002/014/017), and a silent EU-data-residency risk from US-only SaaS defaults. The enforcement stack mirrors the 5-gate conformance pattern — same vocabulary, same agent feedback loop.
