Availability is not invariant preservation
A system can stay up while violating the property it was built to protect. Governed safe degradation asks which reduced states are actually permitted.
Engineering notes
How the platform reasons, and where it stops.
Short technical notes about invariant verification, governed safe degradation, admission and evidence. Every note is scoped to the implementation evidence, and each one states the boundary of what has actually been established.

Unknown is not proof: why λ-Safe refuses instead of guessing
A verifier that treats an undecidable clause as a pass is worse than no verifier at all. How λ-Safe records the boundary of what it actually established.
What an admission decision actually proves
A signed permit is a scoped claim about one action, not a general statement that an actor is trusted. Reading the scope and replay state correctly.
