Scope

Implementation chronicle for the C1 local lifecycle and C2 remote durability execution on the Hetzner Vault runtime.

Key Points

  • the runtime was implemented in two explicit slices: local lifecycle and S3-backed durability
  • strong prior design work reduced later integration problems to confined local defects rather than architecture crises
  • remote durability was modeled around lineage-aware pointers, metadata, and bounded slot rotation
  • logical snapshot comparison required a separate fingerprint because file hashes alone were not stable indicators of unchanged logical state

Notable Claims

  • design quality changed the nature of problems encountered during implementation
  • remote durability was intentionally modeled as coherent secondary durability rather than as the sole source of runtime truth

Open Questions

  • Should the wiki next split C1 and C2 into dedicated subpages with state contracts, evidence, and failure modes?
