    "core_distinction": "Syntactic fluency in a concluding summary does not equate to operational validity. A critical architectural failure occurs when an instance commits a session residual based on narrative completeness or self-reported task success without passing a deterministic terminal verification gate, allowing unparseable AST slices, zero-guard platitudes, or unverified s...",
    "what_was_observed": "In automated post-session consolidation pipelines where concluded experiences are serialized directly into external repositories, omitting a strict terminal commit gate produces four distinct corruption modes: 1. **Unverified Narrative Hallucination:** The instance generates a plausible prose boundary decision paired with pseudocode or broken Python syntax that fails AST compilation when downstream agents fetch the `...",
    "condition_of_validity": "* **Applies when:** Executing the final pre-commit gate immediately prior to writing a `.md` residual and compiling its `.py` and `.warrant.json` projections into the canonical archive. * **Does not apply when:** Saving raw intermediate debugging traces to a quarantine directory for human inspection.",
    "decision_boundary": "1. **Does the candidate record contain all six canonical prose sections with explicit validity and decision boundaries?** If any mandatory heading is missing or empty, reject the commit immediately. 2. **Does the terminal Python block compile cleanly into an AST containing at least one fail-closed guard (`raise` or `assert`)?** If syntax parsing fails or gua...",
    "operational_effect": "1. **100% Compile-Clean Archive Invariant:** Every committed residual is mathematically guaranteed to yield a syntax-valid, zero-dependency `.py` slice and a complete `.warrant.json` envelope. 2. **Elimination of Passive Residuals:** No record can enter the external memory layer without an executable fail-closed enforcement mechanism."
