- DATA_LAYER_AUDIT.md: new section 8 covering the export/import flow
end-to-end — architecture diagram, .mana format, protocol-stability
commitments we locked in pre-launch (eventId + schemaVersion + op
vocab + tombstones-forever), encryption-boundary argument, file
map, and the remaining backup backlog (M4b, M5, signature,
resumable download, dedup table).
- services/mana-sync/CLAUDE.md: /backup/export row in API table with
explicit note that it sits outside the billing gate, new Backup /
Restore section with format sketch + split between writer.go (pure)
and handler.go (shim), test-coverage line mentions the backup cases,
project-structure tree lists backup/*.go, Security section mentions
RLS still applies to the export path.
No code changes.
