Refutes my own claim from the previous commit that slot 01 is an auto-save whose restored mission drifts. savedata has not been written since 2026-08-23; every run today left it untouched (only the .gpd profile files moved), and there is exactly one save, so a wandering save-list cursor cannot explain it either. Decoded the save statically (GDHA + zlib at 0x92, 545 bytes): only SHAB record 0 carries clear data, records 1-15 are zeroed. Three independent readings agree it is Stage 02 -- the 324773 ms clear time is the 05:24.77 that SESSION-2026-08-11 documents for Stage 01, the 4101 points match weapon-datasheet-runtime.md's "Stage 02, At Standby, 5% clear, 4101 P", and the GHAD block at tag+8 gives +52 = 2. Stage 02 is the Acropolis escort mission, which is exactly the roster the last run produced. So the odd run out was the S01 "Glasner Training Area" one -- a TUTORIAL, reached because the nav issued dpad-down + A from a state never confirmed to be the main menu. Fix is two guards: verify screen_id reads `menu` immediately before the dpad, and assert Acropolis is in the definition table before comparing rosters. Caveats kept: the GHAD field base was not isolated by the search (7 candidates, 3 giving stage 2 -- tag+8 chosen because it agrees with the other two readings), and the tutorial mis-selection was not demonstrated by re-running the emulator.
