Invariants

Invariants are the promises bijux-canon-ingest should lose only through a deliberate design decision. If a change weakens an invariant without naming it, trust has already eroded.

What To Check

• name the truths that must survive ordinary changes to prepared ingest behavior
• tie each invariant to the evidence that is supposed to protect it
• treat invariant drift as a design event rather than a routine edit

First Proof Check

• tests and package-local validation surfaces for executable evidence
• caller-facing docs, limits, and risks for the trust story readers actually receive
• release notes and change records when the work alters what others may safely assume

Bottom Line

If bijux-canon-ingest cannot explain why prepared ingest behavior should be trusted after a change, the quality work is still incomplete.
