Collapse docs/adr/ and docs/rfc/ into a single docs/rfc/ with proposed/, implemented/, and rejected/ subfolders. Every file is renamed to yyyy-mm-dd-topic-title.md, where the date is when the topic was first proposed (from git history). ADRs and RFCs that covered exactly the same topic are merged (property-based testing, session persistence); the umbrella RFC 005 stays split across its three implemented decisions, and RFC 006's deferred part-3 (API extractor reports) splits into its own proposed RFC. All cross-references become machine-checkable relative links instead of bare "ADR NNNN" / "RFC NNN" prose. Add a verify-md-links doc-sync gate (scripts/verify-md-links.ts) that checks every relative Markdown cross-link resolves, wired into doc-sync alongside verify-md-wrap. This makes the reorganization self-verifying: the same change that rewrote ~forty inter-doc links adds the check that proves none dangle. Document the cross-link convention in a new docs/AGENTS.md and record the gate as an implemented RFC. doc-sync, typecheck, lint, and the full test suite (667) all pass.

RFC: Mechanical quality gates over prose guidelines
Status: implemented (accepted 2026-06-11)
Context
This codebase is developed primarily by coding agents. Agents follow enforced gates far more reliably than prose conventions, and "a lot of work" is not a cost argument when agents do the labor. Early evidence: tests that didn't typecheck shipped (vitest doesn't typecheck) and were only caught by a review.
Decision
Every AGENTS.md promise gets a command that exits non-zero, wired into git hooks and CI both calling the same package.json scripts:
- Max-strict TypeScript (
noUncheckedIndexedAccess,exactOptionalPropertyTypes, …); tests and examples typecheck in CI viatsconfig.typecheck.json(vendored packages resolve as built declarations). - ESLint strict-type-checked + @stylistic (the house style, enforced); vendored code excluded.
- Per-file 100% coverage on
packages/*/src(v8); unreachable defensive guards carry/* v8 ignore */with stated reasons instead of deletion. - knip (dead code/deps), publint (package correctness), workspace constraints (workspace rules: private, cordis peer+dev, uniform version, ESM).
- lefthook pre-commit (lint staged, typecheck, vendor-manifest guard) and pre-push (tests, hygiene); CI runs the full matrix on node 24/26 plus a demo smoke test driving the echo-agent end to end.
Consequences
- Conventions survive agent turnover; violations fail fast and locally.
- The gates themselves are code to maintain; config changes are reviewed like any change.
- 100%-coverage pressure can produce assertion-free tests — mutation testing is the planned counterweight (see the mutation-testing proposal).
