Observability

Five signal classes across five stages. Only five cells page a human, and four of them are correctness rather than availability.

A dashboard that is an hour stale is an inconvenience; a number that does not reconcile is the failure this platform exists to avoid. v 1.0 · owner Platform Architecture · date 2026-09

What pages

  • Invoice variance outside tolerance
  • An allocation run whose digest does not reproduce
  • A statement whose lines do not sum to its total
  • Unallocated share breaching the 2% SLO

What does not page

  • Dashboard staleness under an hour — an inconvenience, not a failure
  • A single missed export inside the T+2 cutoff
  • Spot interruption on the batch tier

The principle

  • For a measurement platform, being wrong is worse than being late. The alerting reflects that and nothing else
