# 2026-03-05 Session Notes

## KA-2 Sprint Kickoff

Nicholai initiated work on the Knowledge Architecture Phase 2 (KA-2) sprint for the signetai monorepo. The session began with a reference to `SPRINT-BRIEF-KA2.md` and immediate handoff to implementation.

## Prerequisite Verification Strategy

Before diving into KA-2 deliverables, the assistant spun up an Explore agent to systematically verify KA-1 prerequisites were in place. The verification checklist included:

- Migration 019 registration and schema (entity_aspects, entity_attributes, entity_dependencies, task_meta tables)
- Core type exports (EntityAspect, EntityAttribute, EntityDependency in packages/core/src/types.ts and index.ts)
- knowledge-graph.ts helpers in packages/daemon/src/ (upsertAspect, upsertDependency functions)
- Pipeline architecture review: worker.ts, extraction.ts, daemon.ts to understand extraction flow and worker lifecycle
- PipelineV2Config structure in packages/core/src/types.ts
- PipelineJobType values and job enumeration

## Context

Working branch: `fix/knowledge-graph-agent-id-scoping`. Package manager: pnpm. Database: SQLite backend. The approach prioritizes validating existing infrastructure before building new KA-2 components on top of KA-1 foundations.
