exception-safety-spans-tms-and-source-lifecycle
IN derived (depth 6)
The system handles failures safely across both domains: the TMS core resolves exceptional conditions (contradictions via backtracking, challenges via deterministic propagation) while the source integrity pipeline handles its failure modes (missing files, changed content, deleted sources) — no exception in either domain can produce inconsistent or undefined state.
Summary
The system is robust against failures in two independent areas — the truth maintenance engine (which deals with contradictions and belief challenges) and the source file tracking pipeline (which deals with files being moved, edited, or deleted). Neither kind of failure can leave the system in a broken or inconsistent state, because each domain has its own complete set of recovery mechanisms that resolve problems deterministically.
Justifications
SL — TMS exception safety + fail-safe source lifecycle → unified failure safety across both domains
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.
- source-lifecycle-is-fail-safe-and-gapless — The end-to-end fail-safe source integrity pipeline — from convention-based path resolution through collision-resistant SHA-256 hashing to comprehensive drift detection — feeds directly into gapless lifecycle management, ensuring every source material change on disk is detected, surfaced, and managed through the full belief lifecycle without gaps.
Dependents
These beliefs depend on this one:
- rich-governance-is-exception-safe — The system's rich lifecycle governance — deterministic, lifecycle-complete, extending beyond binary truth to metadata-enabled state with full monitoring — operates within an exception-safe framework spanning both TMS core and source lifecycle: contradictions are resolved through deterministic backtracking, challenges reach correct truth states through crash-safe propagation, and source failures degrade gracefully through fail-safe path resolution — ensuring that rich state transitions never produce corrupted or inconsistent lifecycle metadata.
- source-to-tms-integrity-is-deterministic-and-exception-safe — The complete integrity pipeline from source files through TMS truth maintenance is both deterministic (convention-based path resolution, collision-resistant SHA-256 hashing, uniform pure evaluation) and exception-safe (fail-safe source resolution, contradiction-triggered backtracking, challenge-to-justified recovery) — no failure in either source verification or truth maintenance can corrupt system state or produce unpredictable outcomes.
