source-integrity-is-fail-safe-deterministic-and-grounded

IN derived (depth 7)

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).

Summary

The source integrity pipeline is reliable in three reinforcing ways: it handles failures gracefully instead of crashing, it behaves deterministically so results are predictable, and it fits cleanly within the system's architectural boundaries. This conclusion follows from two independent lines of reasoning that converge — one establishing the fail-safe properties of each pipeline stage, and the other confirming that the pipeline operates within the same disciplined architectural framework as the rest of the system.

Justifications

SL — Fail-safe pipeline properties combined with architectural determinism grounding

Antecedents (all must be IN):

  • source-pipeline-is-end-to-end-fail-safe — The complete source integrity pipeline from path resolution through hash computation to staleness detection is end-to-end fail-safe: convention-based resolution returns None on missing files rather than raising exceptions, collision-resistant SHA-256 hashing backfills additively without overwriting, and staleness detection catches all drift with CI-ready exit codes — no stage in the pipeline raises exceptions on adverse conditions, and each stage's output gracefully feeds the next.
  • 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.
