No magic. Just math.
Observability detects the fire. Déjà documents the chain of custody — and proves exactly how it was extinguished. Deterministic linkage, verified gates, audit-ready evidence.
DEJA_LOGIC vs STANDARD_LOGS
- •Events rotate & drift
- •Context lives in heads
- •"Fix" is anecdotal
- ✓Fingerprint → match → evidence
- ✓Verified gates prevent false links
- ✓Audit-ready chain of custody
Chain of Custody Pipeline
INGEST
Pull raw incident evidence from Sentry, Jira, logs — without rewriting your workflow.
ANALYZE
Normalize noise so identical failures map to identical fingerprints.
FINGERPRINT
Compute deterministic IDs that survive refactors and team turnover.
MATCH
Link recurrence to verified fixes — then show the evidence trail.
Trust Engine
File Gate
Matches only if fix touched relevant files.
Rate Gate
Regression rate drops after fix window.
Infra Gate
Rules out infra noise & deploy artifacts.
Feature Flag Gate
Correlates fixes to rollout conditions.
Duration Gate
Verifies fix stability over time.
Hardened Perimeter
Privacy & Compliance HUD
> WE_DON'T_READ_YOUR_CODE
Correlation uses fingerprints and metadata, not source inspection.
> TOKENIZED_IDENTIFIERS
Stable IDs for incidents and fixes without sensitive payloads.
> AUDIT_READY_LOGS
Immutable evidence trail suitable for regulated environments.
Stop solving the same bug twice.
Turn incident history into a permanent asset — deterministic, verifiable, and ready for audit.
