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
