source-integrity-unifies-determinism-exception-safety-and-lifecycle
IN derived (depth 8)
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.
Summary
The source integrity pipeline pulls triple duty from just two foundations. Because the path from source files into the TMS is both deterministic and exception-safe, and because lifecycle governance relies on that same deterministic integrity for staleness and currency decisions, a single mechanism simultaneously guarantees pipeline correctness, safe failure recovery, and sound lifecycle management. Nothing extra is needed to coordinate these three concerns — they all fall out of the same underlying source integrity guarantees.
Justifications
SL — source integrity serves pipeline correctness, exception safety, and lifecycle governance simultaneously
Antecedents (all must be IN):
- 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.
- 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.
Dependents
These beliefs depend on this one:
- source-integrity-and-governance-form-closed-loop — Source integrity enables lifecycle governance by unifying determinism, exception safety, and lifecycle management into a single pipeline, while lifecycle governance achieves gap-free source coverage — forming a self-reinforcing closed loop where source integrity grounds the governance that in turn ensures no source verification gap exists.
