Standardize on the .agents/ directory (shared with project skills):
phases/, user_stories/, reports/, screenshots/, validate.sh, and
phase-sessions/ + pipeline.log all move to .agents/ (git mv preserves
history; runtime artifacts move alongside).
Updates every reference in AGENTS.md, README.md, .gitignore, app
docstrings, and test story headers. Historical KB content in data/
and the runtime pipeline.log transcript are left untouched.
Codifies the 2026-09-05 turbo comparison workflow as a project skill under
.agents/skills/: switch BOR_LLM_CHAT_MODEL in .env, run the fixture gate
(twice, for variance) + the locked derived gate with per-turn wall timing,
interpret the two metrics against the reference model rates (re-read habit:
lite ~100%, turbo ~12%; usage-floor MISS as test artifact; caps as real
regression), record the verdicts byte-exact in TOOL_CALLING_TESTING.md, and
commit the doc. Rules baked in: never touch the battery/thresholds/fixtures,
never edit app code, never commit .env.
