BrainPalace 26.6.30

Added

• Server self-registration: a running server now writes its own runtime.json and
  global registry.json entry (learned from the bound socket) regardless of how it
  was launched, and re-asserts every 180s — fixing servers (orphaned, raw-uvicorn,
  IDE-launched) being invisible to the dashboard.
• Server-side self-heal heartbeat: restarts a dead file watcher or job worker,
  rebuilds a corrupt vector index (crash-safe file-only check), and relaunches the
  web dashboard if it is down (locked, single-launch).
• Dashboard config save now guards against data-incompatible changes: editing the
  embedding provider/model, storage backend, or graph store type while data is
  indexed is blocked with an explanation and a "Save & reindex now" action
  (server exposes a read-only GET /index/fingerprint).
• Per-field help across Storage, GraphRAG, Git Indexing, Reranker, and Session
  Extraction, plus per-section descriptions distinguishing Session Extraction
  (curated summary) from Session Indexing (raw transcript archive/embedding).

Changed

• Single locked writer for registry.json (server registry.py); CLI
  update_registry now delegates to it (no more lockless writes).
• One build_server_command builds the uvicorn argv for all CLI/MCP launch paths;
  foreground + MCP no longer hand-copy the spawn block.
• One render_dashboard_url renders the hot_pink dashboard box for
  init/start/dashboard.

Fixed

• brainpalace config wizard now defaults graphrag store_type to sqlite
  (persistent, temporal) instead of the ephemeral simple, matching the server
  default and the dashboard.
