source-to-tms-integrity-is-deterministic-and-exception-safe
IN derived (depth 7)
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.
Summary
The entire chain from reading source files to maintaining what the system considers true is designed to be fully predictable and safe against errors. If something goes wrong at any point — whether a source file is missing, content has changed, or two beliefs contradict each other — the system handles it gracefully without corrupting its state or producing surprising results.
Justifications
SL — Source integrity and exception safety are independently deterministic across their domains; combining shows the full pipeline is deterministic and exception-safe end-to-end
Antecedents (all must be IN):
- source-integrity-is-deterministic-and-architecturally-grounded — The fail-safe source integrity pipeline — from convention-based path resolution through collision-resistant SHA-256 hashing to comprehensive staleness detection — operates within the same deterministic, architecturally-grounded lifecycle framework as all other system operations, ensuring source verification is both predictable and structurally safe.
- exception-safety-spans-tms-and-source-lifecycle — 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.
Dependents
These beliefs depend on this one:
- source-integrity-unifies-determinism-exception-safety-and-lifecycle — The source integrity pipeline achieves triple assurance from two independent chains: the source-to-TMS path is deterministic (convention-based resolution, collision-resistant SHA-256) and exception-safe (fail-safe across both TMS and source lifecycle domains), while lifecycle governance uses that same deterministic source integrity to drive staleness decisions and belief currency management — source integrity simultaneously serves pipeline correctness, failure recovery, and lifecycle governance.
