Introduce AGENTS.md (root, primary agent instruction file) documenting six
hard-won fixes with explicit DO NOT / WHY, plus executable enforcement so a
future AI cannot delete or reintroduce them:
1. package-lock.json must be generated with npm 10 (Docker's npm 10.9.8).
npm 11 drops the top-level @emnapi/core + @emnapi/runtime entries npm 10
needs, breaking the tag-triggered Docker build at `npm ci` (happened on
v1.0.14). Add scripts/verify-lockfile-npm10.mjs + .npmrc + a Dockerfile
fail-fast check + a CI step + tests/unit/lockfile-npm10-guard.test.js.
Also re-fix the lockfile itself (regenerated with npm 10.9.8).
2. Tests must never write to the real ~/.9router DB (isolateDataDir).
3. Hidden providers must not leak into Usage (usageProviders !p.hidden).
4. codebuddy-intl connection test + OAuth identity.
5. Fork-only features that must survive upstream syncs.
6. Upstream sync procedure.
Each marker cross-references AGENTS.md and the covering test. CLAUDE.md now
points to AGENTS.md at the top. Verified: build ok, guard script passes,
full suite leaves the real DB count unchanged (38), 0 new regressions.
Top-level guide for Claude Code / AI coding agents working in this repo,
complementing docs/ARCHITECTURE.md and open-sse/AGENTS.md.
Docs-only: PR's incidental code changes were dropped as they reverted #2366.
