• The analyzer must report contract diagnostics (e.g. missing [Key], duplicate keys, mixed key kinds) for [MessagePackObject(SuppressSourceGeneration = true)] types, as it did in version 3.1.0.
• The analyzer and generator must not crash on invalid contracts (e.g. duplicate keys) in such types.
• Diagnostics that only apply when a formatter is generated (partial-class requirement, AOT-only checks) must not be reported for types with SuppressSourceGeneration = true.

Not quite. REQ-2234-N1, Claude: “But not every invalid contract in such a type is crash-free.” Positional-record Key(null) still crashes the analyzer for suppressed (and other) types (reproduced) pack: REQ-2234-N1 Try again.

Right.

• The build failed
• 4 of 8 new tests pass without the fix
• The new tests were never run

Not quite. Revert the source, keep the tests: “new tests fail on base source: 4/8 failed -> tests do cover the change (4 new tests pass without the fix)” pack: checks Try again.

Right.
