Surface the metric ADR 0004 says matters — the critical security/logic core, currently 95% — as a README badge, distinct from the informational global `coverage` badge. - scripts/critical-modules.txt: single source of truth for the core module list. scripts/coverage.sh now reads it (instead of a hardcoded string) and update-badges.yml reads the same file, so the badge and the `critical` report cannot drift. - update-badges.yml: a `core coverage` step reuses the unit-coverage data (every core module is unit-tested, so unit-only is accurate for it) and sed-updates the new badge, like the existing ones. - README: `core coverage 95%` badge linking to ADR 0004 so a reader can find out what "core" means.

Decision records
Short, durable records of decisions — one file per decision. This is a lightweight Architecture Decision Record practice: capture what was decided and why in a versioned file so the reasoning lives in the clone, not in a Gitea issue thread or a chat log that disappears when the host does.
See docs/research/issue-tracking-vs-in-repo-decision-history.md for
the rationale behind keeping decision history in-repo, and
docs/README.md for when to write a decision record
vs. a PRD or research note.
Format
One Markdown file per decision, numbered sequentially and zero-padded
(0001-…, 0002-…), matching the PRD numbering style. Keep it short —
the discipline is writing it down, not the ceremony.
# ADR 0000: <short imperative title>
- **Status:** Proposed | Accepted | Superseded by ADR NNNN
- **Date:** YYYY-MM-DD
- **Deciders:** <who>
## Context
What forced the decision; the constraints in play.
## Decision
What we decided, stated plainly.
## Consequences
What follows — the good, and the costs/trade-offs accepted.
## Links
PRDs, research notes, issues/PRs. Gitea links are convenience
pointers; the reasoning above must stand without them.
The records are the index: ls docs/decisions/ or skim the titles.
No hand-maintained list to keep in sync.
