The system detects that it needs to improve
PROMETHEUS ECE starts from operational evidence: recurring failures, repeated manual tasks, performance degradation, unstable integrations, missing functions or patterns that justify a new capability.
The candidate is born outside production
The improvement hypothesis does not modify the active system. An isolated candidate is created, built, tested, attacked and compared with the current version.
Compare before promoting
The improvement must demonstrate that it beats a baseline without degrading existing guarantees. Regression, fault injection, adversarial audit and differential comparison are part of the path.
No self-promotion
A candidate may prove objectively better and still have no authority to replace production. Evidence reaches a responsible human who approves, rejects or asks for another iteration.
Rollback as a condition, not decoration
Promoting a version without a verified return path contradicts controlled evolution. Every promotion must preserve a verifiable rollback path.
Input: a pattern of recurring incidents. Process: PROMETHEUS formulates an improvement, builds a candidate outside production and compares it through regressions, fault injection and metrics. Output: evidence for a human to approve or reject the new version.
