# 2026-02-23 Session Notes

## Documentation Gap Audit & Update Plan

Nicholai initiated a comprehensive documentation audit session for the signetai project. A detailed plan was provided identifying and prioritizing documentation gaps across the codebase.

## Key Findings

**Priority 1 (Incorrect Content):**
- DASHBOARD.md references non-existent UI tabs (DiagnosticsTab, AnalyticsTab, etc.); actual tabs are Config, Settings, Memory, Embeddings, Logs, Secrets, Skills
- DIAGNOSTICS.md missing the `update` domain (weight 0.11)

**Priority 2 (Missing API Endpoints):**
- Three undocumented endpoints: `GET /api/embeddings/projection`, `GET /api/repair/embedding-gaps`, `POST /api/repair/re-embed`
- CLAUDE.md endpoint table also needs these three entries

**Priority 3 (New Subsystem):**
- Tray app (packages/tray/, Tauri v2) shipped with zero documentation. Architecture: Rust handles tray lifecycle/menus, TypeScript polling loop for state detection. Adaptive polling: 5s when running, 2s when stopped. Linux uses systemd with fallback to bunx discovery.

**Priority 4 (Pipeline Gaps):**
- Three pipeline modules undocumented: provider.ts (Ollama/Claude LLM abstraction), reranker.ts (timeout-guarded search reranking), url-fetcher.ts (document ingest with 30s timeout, 10MB max)
- ARCHITECTURE.md schema section incomplete; needs full table of 16 tables across migrations

**Priority 5-6:** CLI embed subcommands and internal modules (content normalization, UMAP algorithm notes).

## Deliverables

Eight documentation files require updates or creation, grouped by priority. Verification steps include grep checks, cross-reference validation, and schema consistency verification.
