revision-is-exception-safe-and-recoverable
IN derived (depth 6)
Every revision mechanism — whether normal (outlist defeat, dialectical challenge/defend) or exceptional (contradiction-triggered backtracking, graph inconsistency) — is simultaneously safe (handled without crashes or corruption), traceable (producing deterministic artifact trails), and recoverable (providing guided restoration hints for cascade victims) — the system never enters an unobservable or unrecoverable state regardless of failure mode.
Summary
No matter how a belief gets revised — whether through routine updates, contradictions, or unexpected errors — the system always handles it cleanly. It won't crash or corrupt data, it leaves a clear trail of what changed and why, and it gives you enough information to restore anything that was affected by the change.
Justifications
SL — Exception safety combined with traceable recoverability eliminates all unobservable or unrecoverable revision outcomes
Antecedents (all must be IN):
- all-exceptions-are-safely-handled — The system handles both automated exceptions (contradictions triggering dependency-directed backtracking) and manual challenges (irreversible premise-to-justified transformation via dialectics) safely — exceptional conditions from any origin reach correct truth states through deterministic propagation, and no exception pathway corrupts network consistency.
- all-revision-mechanisms-are-traceable-and-recoverable — Every belief revision mechanism — contradiction resolution (dependency-directed backtracking with consistent nogood IDs) and defeat reversal (automatic outlist-driven recovery with surgical restoration hints) — provides complete traceability and guided recovery across all revision paths.
Dependents
These beliefs depend on this one:
- lifecycle-governance-is-exception-safe-and-source-grounded — Metadata-enabled source-grounded lifecycle governance is backed by exception-safe recoverable revision mechanics — lifecycle decisions about staleness and source integrity are protected by the same exception handling that safeguards contradiction resolution and dialectical transformation.
- revision-is-richly-governed-and-exception-safe — The belief revision system simultaneously governs state richer than binary truth values — metadata-enabled lifecycle management including retraction reasons, staleness markers, and access tags — while remaining exception-safe and recoverable under all failure conditions, ensuring that metadata-carried lifecycle state is never corrupted by exceptions.
- topology-complete-transitions-are-exception-safe — Every belief state transition is simultaneously topology-complete (reaching all transitively dependent nodes including outlist-connected ones), traceable (producing deterministic structured diffs), exception-safe (handling contradictions and challenges without corruption), and recoverable (providing guided restoration hints for cascade victims).
