Module verify 

ev verify: R1 (closed schema), R2 (check shape), R4/R6 (id == hash + chain integrity), R3 (self-evolve subject) + R5 (blame present + forbidden-op).

Functions

unknown_key_warnings

Forward-compat surfacing (T3): a warning: (NOT a violation) per tolerated unknown top-level key, so a typo’d field name stays visible instead of silently parsing through. schema_version is read LAZILY here — at the tolerate-vs-reject decision — so a future reader can sharpen the rule per declared baseline without making schema_version a parsed Config field.

verify

Returns the list of violations (empty == clean). Reports ALL of them.
