rich-governance-has-verified-evolution-tolerance

OUT derived (depth 10)

The system's rich governance — deterministic, exception-safe, and source-grounded — combined with gap-free lifecycle source coverage achieves verified evolution tolerance at all system boundaries when the evolution tolerance audit (issue #121) confirms that all boundaries have documented forward-compatibility, completing the governance guarantee across the format/schema evolution dimension.

Summary

When the system's governance is both fully deterministic and error-resilient, and every source file is tracked without gaps, the combination should guarantee that format and schema changes can be handled safely at every system boundary — but only once a specific audit (issue #121) confirms that forward-compatibility is actually documented everywhere. This claim is currently not held, meaning either the governance properties or the gap-free coverage (or both) have been retracted, so the evolution tolerance guarantee does not follow.

Justifications

SL — rich governance extends to verified evolution tolerance after audit completion

Antecedents (all must be IN):

  • rich-governance-is-deterministic-exception-safe-and-source-grounded — Rich lifecycle governance simultaneously achieves end-to-end determinism from revision semantics through source integrity and exception safety across TMS and source lifecycle — governance is both predictable in its state trajectories and resilient to all exceptional conditions.
  • lifecycle-governance-achieves-gap-free-source-coverage — Metadata-enabled lifecycle governance with deterministic source integrity and exception-safe recoverability achieves truly gap-free source coverage — every source file is verified, every lifecycle decision is grounded in verifiable source state, and no silent source gap undermines governance decisions about staleness or retraction.

Unless (any of these IN defeats this justification):

  • issue-121-evolution-tolerance-audit — Issue #121: Audit evolution tolerance at all system boundaries — not all boundaries have documented forward-compatibility mechanisms
