source-integrity-is-deterministic-and-architecturally-grounded
IN derived (depth 6)
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.
Summary
The system's source integrity checking — finding files by convention, hashing them with SHA-256, and detecting when they go stale — follows the same predictable, structurally safe patterns as every other part of the system. This means verifying whether source materials have changed isn't a bolted-on concern but is fully embedded in the deterministic lifecycle, so changes on disk are always caught and handled reliably without special-case logic.
Justifications
SL — Fail-safe source lifecycle + deterministic grounded lifecycle → source integrity anchored in deterministic architecture
Antecedents (all must be IN):
- 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.
- lifecycle-is-deterministic-and-architecturally-grounded — Gapless lifecycle management is doubly reinforced: deterministic reasoning ensures predictable state trajectories with full monitoring, while architectural safety provides the structural foundation through clean layer boundaries and atomic mutations.
Dependents
These beliefs depend on this one:
- determinism-spans-revision-semantics-through-source-integrity — Determinism is maintained end-to-end from belief revision semantics through source integrity verification: revision operations produce deterministic traceable state transitions (structured before/after diffs with controlled irreversibility), AND the source verification that triggers revision actions is itself deterministic and architecturally grounded (fail-safe path resolution, exact SHA-256 comparison, clean layer boundaries) — no step in the revision-triggered-by-source-change pathway introduces non-determinism.
- lifecycle-governance-has-deterministic-source-integrity — Metadata-enabled lifecycle governance is backed by deterministic, architecturally-grounded source integrity — lifecycle decisions about staleness and belief currency rest on collision-resistant SHA-256 hashing within clean three-layer boundaries, ensuring that the source-grounding of lifecycle governance is itself structurally sound and deterministic.
- source-integrity-is-fail-safe-deterministic-and-grounded — The source integrity pipeline achieves triple assurance from two independent chains: fail-safe operation (convention-based path resolution returning None on missing files, collision-resistant SHA-256 hashing with additive backfill, comprehensive staleness detection) combined with architectural determinism (grounded within clean layer boundaries ensuring predictable state trajectories).
- 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.
