Enum PinVerdict 

pub enum PinVerdict {
    Absent,
    Match,
    Mismatch,
    Malformed,
    Undetermined,
}

What an engine pin says about the build that is running. Data, not a print-and-exit, so every branch is testable — including the two that MUST NOT change the exit code.

Variants

Absent

No pin, or a pin qualified for another implementation. Today’s behaviour, exactly.

Match

Mismatch

A different version — the engine↔baseline coupling is broken. Exit 2 (UNEVALUABLE, never 1).

Malformed

Present but unreadable (engine latest, a bare engine, trailing junk). Exit 2: a pin that cannot be read is a guard the operator believes is on. This is the one place §6.2’s warn-and-skip posture INVERTS — skipping a key that ADDS something costs that key; skipping a PIN costs the guard.

Undetermined

Well-formed, and this build cannot state its own release. UNANSWERABLE — §3.1’s rule applies: disclosed, never scored, INCLUDING as satisfied.
