Development record

the .abcd namespace documents lag the tree in four places: .abcd/README.md describes only the three subdirectories and none of the nine tracked root files the binary reads; the config/ directory and its three members are documented nowhere; the brief's canonical layout tree lists corpus.json which does not exist and nothing reads (annotate as the itd-25 design target rather than delete); and both CLAUDE.md and .abcd/README.md misstate .work.local/'s contents (missing reviews/ — the intent-audit receipt outbox — and private-names.txt, the per-machine banlist layer). One documentation sweep, framed as an index pointing at the owning records, not duplicated schemas.
