## Accumulated Context
### Decisions
Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:
- Init: Fan-out + in-memory merge query pattern chosen (avoids Cartesian product JOINs)
- Init: Read-only DB routing enforced — constructor injects DbR only, no GetDbW() in package
- Init: All existing finance.* utilities (IsGamePassOrder, ComputeProfit, etc.) must be reused, not re-derived
- Init: Phase 2 (Fragment breakdown) requires schema verification of fragment_synthesis_logs join path before implementation
### Pending Todos
None yet.
### Blockers/Concerns
- Phase 2: fragment_synthesis_logs join path and cost formula not yet verified — requires schema review during Phase 2 planning
- Phase 1: SQLite test compatibility for CAST(AS SIGNED), GREATEST(), LIKE 'GP%' — must use Go-layer helpers or conditional SQL paths in integration tests
