Govern evolution, do not allow self-rewriting
PROMETHEUS ECE governs the controlled-evolution cycle. It starts from evidence of a limitation, defines a baseline and comparison criteria, and preserves traceability between the current version and a successor candidate generated outside production by OrvixLabs' engineering infrastructure.
No self-promotion
The engine does not grant authority to a new version simply because it was generated or passed a test. Proposal, verification and promotion are deliberately separated: a candidate may perform better on selected metrics and still be unacceptable because of regressions, operational risk or residual uncertainty.
The candidate starts outside production
The next generation is never written directly over the active system. It is built in isolation, under explicit contracts and a controlled tree. It then faces regression tests, fault injection, adversarial cases and comparison against known results before promotion is even possible.
Compare against a baseline, not an impression
An evolution only matters if it can explain what improves and what is sacrificed relative to the current version. PROMETHEUS preserves metrics, hashes, test evidence, behavioral changes and acceptance conditions so the comparison can be repeated and audited.
Evidence can recommend. It cannot promote.
PROMETHEUS records what changed, what improved, what degraded and what uncertainty remains. A candidate may pass every test and still have no authority to replace production. The final decision belongs to a responsible human. Human approval is part of the architecture, not a ceremony added afterward.
Rollback is a condition
Every promotion must preserve a verifiable path back. An evolution that cannot return to a known version is not under control. The ability to degrade, stop or reverse a candidate matters as much as the ability to generate it.
Next generations, not silent versions
The objective is not invisible continuous change. It is to let systems have new generations justified by evidence: identifiable, comparable, attackable and rejectable candidates. Evolution exists; authority remains human.
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.
