Engineering notes on evidence-backed recovery of deployed software.https://kodeback.com/en-ushttps://kodeback.com/journal/calibrating-semantic-renames/https://kodeback.com/journal/calibrating-semantic-renames/A model’s confidence is not a rename safety threshold. Reliable automation needs adjudicated examples, independent evidence, risk curves, and a protected-surface veto.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/client-side-recoverability-architecture-risk/https://kodeback.com/journal/client-side-recoverability-architecture-risk/Frontend code is expected to be recoverable. Risk rises when recoverable logic includes secrets, entitlement decisions, privileged host channels, or server-authoritative rules.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/donor-evidence-candidate/https://kodeback.com/journal/donor-evidence-candidate/A recovery workspace becomes safer when deployed bytes, derived evidence, and editable source have different owners and different authority.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/identify-vendor-code-before-rewriting/https://kodeback.com/journal/identify-vendor-code-before-rewriting/Production JavaScript mixes application logic, third-party libraries, generated wrappers, and bundler runtime. Cleanup should begin only after those ownership boundaries are measured.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/protected-surfaces-in-semantic-cleanup/https://kodeback.com/journal/protected-surfaces-in-semantic-cleanup/Routes, storage keys, event names, asset identities, host channels, and serialized fields can look like bad identifiers while acting as external contracts.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/source-recovery-must-be-restartable/https://kodeback.com/journal/source-recovery-must-be-restartable/Long recovery work survives interruptions only when stages are checkpointed, evidence is freshness-bound, and restart decisions are explicit.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/runtime-smoke-is-a-contract/https://kodeback.com/journal/runtime-smoke-is-a-contract/A candidate that starts is not necessarily a candidate that booted correctly. Runtime smoke needs declared routes, readiness, errors, resources, and ownership evidence.Wed, 12 Aug 2026 00:00:00 GMThttps://kodeback.com/journal/source-maps-are-a-fast-track/https://kodeback.com/journal/source-maps-are-a-fast-track/Source maps can restore authored files and names, but they do not by themselves recover a reproducible project or prove runtime ownership.Wed, 12 Aug 2026 00:00:00 GMT
