Bounded subset of RFC-OPENBRAIN lifted from lab/lthn.ai shim into the
OSS BrainService at php/Services/BrainService.php:
- search(query, filter, pagination): Elasticsearch path first, falls
back to MariaDB if ES is unavailable. Operates on active/latest
memories only.
- discoverTags(filter): tag-cloud / popular-tags discovery scoped to
authenticated org(s).
- listScopes(filter): org/project distribution counts for the
authenticated session.
All three:
- Enforce bounded inputs (per #1001 patterns)
- Honour org auth (per #312 patterns)
- Only operate on active/latest memories (active=1, deleted_at IS NULL)
Self-hosters now get the same discovery surface that lab/lthn.ai
exposes — no need to fork the OSS service to access these features.
Pest covers: bounds-violation rejection, fallback behaviour, scoped
discovery returning correct org/project breakdowns.
Lab-only features still out of scope for this lane (would pull in
extra schema/models/events): agentContext, recall feedback,
maintenance lifecycle (reindex/consolidate/clean/prune). Those need
follow-up tickets if/when bounded-lift becomes possible.
