Problem
Historical and damaged system material can be mistaken for current authority during recovery.
ENGINEERING CASE STUDY
Recover the system without promoting the archive.
Engineering case study: Lazarus-style recovery separates historical evidence, schema conformance, runtime reconstruction and promotion gates.
OVERVIEW
Lazarus recovery and hardening
Engineering case study: Lazarus-style recovery separates historical evidence, schema conformance, runtime reconstruction and promotion gates.
Method
Source paths, schema state and runtime evidence are reconstructed separately.
Result
Recovered state can be promoted only after explicit conformance and acceptance.
Boundary
Recovery evidence may explain lineage without automatically becoming live runtime truth.
