AGENTS.md is hierarchical (nearest-file-wins), so the root is the map and each
organ owns a scoped AGENTS.md with local build/run/invariants: src/ichor (Pony
bus, S1 membrane), src/endocrine (R/Octave organ tests), mafiabot_core (Ada
border + COBOL vault, alr-not-gprbuild, S3). Scopes kept non-overlapping to
avoid the divergence trap rather than sprinkling sync notes.
