Replace the 265-line data dump (35 modules × 3 items) in MI system prompts
with a trigram-ranked knowledge index that surfaces only the top-18 most
relevant entries per query. Adds per-space conversation memory persisted
to disk for cross-session context.
New files:
- server/mi-trigrams.ts — trigram + Jaccard similarity utilities
- server/space-knowledge.ts — SpaceKnowledgeIndex with 5-min TTL cache
- server/space-memory.ts — SpaceMemory with debounced disk persistence
Changes:
- mi-routes.ts: ~280 lines removed, replaced with ranked index call
- sync-instance.ts: cache invalidation on doc changes
- rauctions/mod.ts: fix ModuleScoping type (defaultScope, userConfigurable)
- mcp-tools/ragents.ts: fix AccessResult property access (claims.username, claims.sub)
~80% token reduction per MI request (~6,300 → ~1,320 tokens).

Browser-side:
- Fix switchSpace() to LRU-evict idle space WebSocket connections (cap: 3)
- Add runtime.unsubscribe() to disconnectedCallback in 24 components
- Fix DocSyncManager.unsubscribe() to clean up syncStates, timers, listeners
- Fix 14 components leaking RAF loops, ResizeObservers, MutationObservers,
document/window listeners, setIntervals, MapLibre WebGL contexts, and
AbortControllers on disconnect
- Deduplicate Automerge WASM: module builds now use global shim from
shell-offline instead of bundling ~2.5MB each (8 modules affected)
Server-side:
- Add LRU eviction to SyncServer.#docs (cap: 500, evicts idle docs with
no subscribers, persists to disk before eviction)
- registerWatcher() now returns unsubscribe function
Data:
- Cap unbounded CRDT arrays: rexchange chatMessages (200), rcart events (200)

Implement the 4-layer data model (device → encrypted backup → shared sync → federated):
- Extract shared encryption-utils from community-store (deriveSpaceKey, AES-256-GCM, rSEN format)
- Encrypt module docs at rest when space has meta.encrypted === true
- Fix relay mode persistence: relay-backup/relay-restore wire protocol + .automerge.enc blob storage
- Add backup store + REST API (PUT/GET/DELETE /api/backup/:space/:docId) with JWT auth
- Add client BackupSyncManager with delta-only push, full restore, auto-backup
- Wire backup stubs in encryptid-bridge to BackupSyncManager
- Add rspace-backups Docker volume
- Create docs/DATA-ARCHITECTURE.md design doc with threat model and data flow diagrams
