Assurance Infrastructure · Lazarus
Lazarus is the recovery and hardening family for damaged, incomplete or transitional system state that must be reconstructed under explicit evidence boundaries.
Recovery is an evidence problem before it is a repair problem. Lazarus separates schema, source paths, runtime conformance, reconstruction and hardening, so restoring a system does not quietly turn into historical fiction. Recovered state has to earn promotion, and what cannot be evidenced stays held.
Recovery starts from identified surviving sources and lineage rather than assumption: disk images, database dumps, mailbox exports, file shares, paper scans, decommissioned SaaS exports.The starting point is evidence, not a best guess about what used to be true.
Recovered state is tested against the contract it is supposed to satisfy before it is trusted.Conformance gaps are recorded, not smoothed over.
Operational state can be rebuilt without treating every historical artifact as current authority.Old records inform recovery; they do not automatically become live truth.
A recovered system must pass explicit acceptance before it becomes active state.Promotion is a decision with a receipt, not a default.
Workstations, shared drives and legacy servers move to governed cloud state through declared inventory, hash-chained transfer, and conformance testing at landing.Cutover happens per workload with rollback receipts, never as a blind weekend switch.
Decade-old archives, PST mailboxes, orphaned databases and vendor formats nobody supports get inventoried, hashed, parsed against explicit schemas, and either admitted with lineage or held as reference-only.Bit rot and silent corruption surface as findings, not surprises.
Disk and mailbox exports, database dumps, file-share trees, scanned paper, SaaS takeouts, registry exports, manifests and lineage ledgers.Each carries source identity and capture context into reconstruction.
Lazarus addresses identity mapping across old and new directories and schema drift between legacy apps and cloud targets.It also handles cutover windows with rollback evidence, and deduplication so migrated copies never inflate into false independent records.
Current Evidence
Reconstruction starts from identified surviving sources and lineage, not assumption.
Recovered state is tested against the contract it must satisfy before promotion.
Each migrated workload must carry inventory, hash chain, conformance result and rollback path.
State that cannot be evidenced stays held rather than promoted as current authority.
Proof
Lazarus case material records schema freeze, conformance gaps, reconstruction decisions and the evidence used to promote or hold recovered state.
