What

Adds localStorage persistence to the Spatial Memory Schema so memories survive page reloads.

Closes #1158

Changes

nexus/components/spatial-memory.js

  • Auto-save: placeMemory() and removeMemory() now call saveToStorage() after every mutation
  • Auto-load: init() calls loadFromStorage() to restore saved memories
  • Change detection: _indexHash() compares memory IDs to avoid unnecessary writes
  • Quota handling: On QuotaExceededError, prunes oldest archive-region memories (25%) and retries
  • clearStorage() for manual reset
  • saveToStorage() / loadFromStorage() exported in public API

Verification

  1. Place a memory → reload page → memory reappears in same position
  2. Remove a memory → reload page → memory stays removed
  3. Console shows [Mnemosyne] Saved N memories to localStorage on mutations
  4. Console shows [Mnemosyne] Restored N memories from localStorage on load

Implementation Complete

Changes: Added localStorage persistence to spatial-memory.js:

  • Auto-save on placeMemory() and removeMemory()
  • Auto-load on init() with version checking
  • Change detection to avoid unnecessary writes
  • Quota handling (prunes 25% of archive memories on overflow)
  • clearStorage() for manual reset

Note: perplexity bot auto-added REQUEST_REVIEW which blocks API merge. Manual approval needed via the web UI → #1159
