Replace the single file-structure.md with a stratified layout designed
for AI/agent skill consumption: tables and concrete identifiers over
prose, files loaded on demand, content separated by churn rate.
Layers:
- architecture/ stable structural reference (overview, source-map,
test-map, data-flow)
- patterns/ memory, commands, autocomplete, events, xmpp,
encryption, ui, plugins
- testing/ unit-tests, stubs, functional-tests, bench
- build/ local, docker, ci
- playbooks/ add-command, add-test, add-autocomplete,
add-event-handler, add-encryption
- gotchas.md append-only dated entries (seven seed entries)
- wip/ branch-specific notes; deleted on merge to master
Stable layers describe cproof on master only. In-flight feature
branches (currently feat/ai) get a single file under wip/.
INDEX.md is the entry map with churn labels; SKILL.md is the
always-loaded skill hint pointing to it.
