fix(cockpit): report spend coverage instead of implying a complete total - #48
Merged
Merged
Conversation
Total spend summed only cost evidence that producers attached to attempt terminal events, so a window where most operations carry no cost read as a complete number. Add operation-level cost coverage (operations with at least one costed terminal attempt over all in-range operations), surface it on the Reported cost tile, switch the spend donut label to 'Known spend' while coverage is partial, and state explicitly how many operations are unknown and excluded rather than counted as $0. Stale materialized snapshots are rejected so cached projections rebuild with the new fields.

Use attempt-level coverage for all spend-completeness signals.
operationCostEvidence only proves that each operation has some cost evidence. It does not prove that every included terminal attempt has cost evidence. A costed and an uncosted attempt for one operation can therefore make the donut label, reported-cost tile, and coverage note imply complete spend.
Use snapshot.coverage.costEvidence for these spend signals. Keep snapshot.coverage.operationCostEvidence as the separate operation-level coverage metric.

Why
The spend tile summed only the cost evidence producers attached to
attempt.terminalevents. For Phosphene production that rendered as $4.36 for a window whose own rate card puts believed provider cost near $66: instrumentation only started 2026-08-23, so 71% of historical operations never carried attempts, and failed attempts never carry cost. The total therefore read as a complete number while covering ~22% of operations.What
