The Governance Gap in Your Toolchain
Observability detects the fire. Git stores the ash. Déjà provides the Chain of Custody that proves exactly how it was extinguished.
The Cost of Audit Failure
In software engineering, this is called Regression — a bug that was fixed months ago silently reappears, forcing your team to diagnose, debug, and patch the same issue twice.
Institutional Memory Loss
High-performing teams suffer from regression not from lack of skill — but from lack of deterministic memory. Observability tools tell you something broke. Version control tells you who changed code. But nothing bridges the gap to remember exactly how a specific crash was resolved in the past.
Without Déjà, your institutional memory walks out the door when an engineer leaves — or disappears the moment a Slack thread gets archived.
Three repeatable scenarios
Déjà is built for the real-world ways regressions are created — quietly, unintentionally, and repeatedly.
Single Point of Failure (SPOF)
Unchecked Regression Drift
Audit Chain Breakage
Why not just use GitHub or Sentry?
We integrate with them — but we do what they cannot: deterministic root-cause and resolution memory.
Competitors rely on probabilistic AI (LLMs) or manual tagging (humans updating Jira).
Déjà is deterministic. We do not guess. We correlate runtime anomalies to historical resolution artifacts — and prove it worked.
Déjà doesn't "suggest." It recalls and validates. Confidence is gated by rate reduction + traffic criteria.
The Cost of Audit Failure
Efficiency is a "vitamin." Compliance is a "painkiller." See the metrics that matter to governance teams.
From Weeks to Seconds. Without Déjà, proving a fix required manual investigation across multiple systems. With Déjà, the Chain of Custody is instant.
From Unknown to Capped. Déjà's immutable evidence log provides defensible proof of incident resolution, reducing compliance risk.
Why We Reject Probabilistic Resolution
The industry is rushing toward AI-based 'root cause analysis.' We believe this is dangerous. An AI that guesses right 90% of the time is catastrophic the 10% of the time it is wrong.
Déjà is built on a different axiom: Deterministic Verification. We do not infer. We do not predict. We trace. If we cannot mathematically prove the link between a crash and a fix, we remain silent. We sell certainty, not probability.
Stop solving the same bug twice.
Sarah fixed it three months ago. Don't let a revert erase her work. Deploy institutional memory today.
