The matrix subsystem was removed in a prior commit. This commit cleans
up the small leftovers that grep found:
- docker-compose.macmini.yml: dropped the "Matrix Stack" port-range
comment, the "matrix" category from the naming convention, and a
stale watchtower comment about Matrix notifications.
- packages/credits/src/operations.ts: removed AI_BOT_CHAT credit
operation type and its definition. It was the billing entry for "Chat
with AI via Matrix bot" — no callers left.
- services/mana-credits gifts schema + service + validation: removed the
targetMatrixId column / param / Zod field. The corresponding
PostgreSQL column was dropped manually with
`ALTER TABLE gifts.gift_codes DROP COLUMN target_matrix_id` on prod.
- docker/grafana/dashboards/{master,system}-overview.json: removed the
`up{job="synapse"}` panel queries — they would have shown No Data
forever now that Synapse is gone.
Production-side cleanup performed in parallel (not in this commit):
- Stopped + removed mana-matrix-{synapse,element,web,bot} containers
- Removed mana-matrix-bot:local, matrix-web:latest,
matrixdotorg/synapse:latest, vectorim/element-web:latest images (~3 GB)
- Removed mana-matrix-bots-data Docker volume
- Removed /Volumes/ManaData/matrix/ media store (4.3 MB)
- DROP DATABASE matrix; DROP DATABASE synapse; on Postgres
Cosmetic leftovers intentionally untouched:
- Eisenhower matrix in todo (LayoutMode 'matrix') — productivity concept
- ${{ matrix.service }} in .github/workflows — GitHub Actions strategy
- services/mana-media/apps/api/dist/.../matrix/* — stale build output
(not in git, regenerated next mana-media build)
