Refactor AGENTS.md from encyclopedia to map; move spec into docs/ Splits the 990-line AGENTS.md into a 184-line map (architecture, where-to-find index, always-on invariants, capability matrix, maintenance contract) plus 18 new docs/*.md files holding the deep content per topic (storage, schema and query languages, indexes, embeddings, branches/commits, runs, merge, changes, execution, policy, server, CLI reference, audit, errors, CI, constants, v0.3.1 notes). Adds scripts/check-agents-md.sh and a check_agents_md CI job that verifies every docs/ link in AGENTS.md resolves and every doc in the canonical set is linked. CLAUDE.md remains a symlink to AGENTS.md. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> 2026-04-28 23:31:08 +02:00			`# Constants & Tunables (cheat sheet)`
