Measured post-2050 input anchors and PNG review artifacts for the TD2 SDL port

Measured post-2050 input anchors and PNG review artifacts for the TD2 SDL port The current TD2 SDL runtime already had scripted input and a first menu handoff mutator, but it still flattened the post-2050 default-rival corridor into a mostly generic rail. This checkpoint moves one step deeper into a SNES-mimetic path: promoted exact no-input scheduler anchors at frames 2052, 2053, 2083, 2104, and 2125 overlaid the traced default-rival A route on top of those anchors carried measured fields instead of heuristics: state_09a2, state_09a8, state_137c, dp_0020, dp_0022, dp_0053, and dp_0054 taught the runtime dump path to emit PNG siblings for every PPM artifact, including compare outputs The useful practical effect is twofold. First, the port now has a grounded post-2050 mutation surface that is tied directly to probe evidence instead of broad guessed gameplay logic. Second, the same runtime artifacts that validate the port are now immediately usable by design review without manual convers
