24 tests for the load-bearing logic introduced by the previous commit:
`src/services/__tests__/operator-fees.test.ts` (10):
- canonical v1 payload with components parses cleanly
- absent schema_version treated as v1 (back-compat with cassette config
doc that shipped without one)
- unknown top-level keys silently ignored (v2 forward-compat)
- absent `components` → WARN + zero breakdown (graceful degrade,
producer-mandatory at v1 but consumer-safe)
- components present but sums disagree with totals → WARN + still
parses (totals authoritative per coord log §`14:25Z`)
- tiny float drift (well under 1e-6) does NOT trip the consistency
assert
- required fields missing → throws
- non-numeric component → throws with the offending key in the message
- FEE_CAP_PER_DIRECTION exposed at 0.15
`electron/__tests__/state-store-fees.test.ts` (14):
- null pre-apply (`getFeeConfig` + watermark)
- round-trip via getFeeConfig after applyFeeConfig
- upsert on subsequent newer event (singleton id=1)
- watermark dedup: rejects equal AND older event.created_at
- persisted row unchanged when stale event is rejected
- 15% per-direction cap: rejects above-cap on either direction
- accepts at the cap boundary exactly
- rejects negative + non-finite fractions
- schema_version < 1 rejected
- non-integer event_created_at rejected
- watermark does NOT advance when payload validation fails (atomicity)
Uses in-memory SQLite (`:memory:`) — fresh DB per test, no on-disk
artifacts, no parallel-test interference.
