TextIndex in sylpheed-formats::localization already indexes per-phase objective text under S<NN>_P<n>_Objective_<i>, with hints and lose conditions alongside. Querying it settles what the wave work spent many iterations circling, and a disc test now pins it. Stage 02 phase 1 is "Shoot down all invading enemy fighters while watching out for attacks on the ACROPOLIS", losing if the ACROPOLIS is sunk. Phase 2 is "Protect the Admiral's ship the CALIBAN until it has entered the safe zone", losing if the CALIBAN is sunk. Phase 3 is "Destroy the interstellar cruise missiles headed for Schlos Base", matching phase 3's roster of exactly nine ISCMissile and SUBOBJ_013. That explains the phase advances and shows they are not all the same kind. Phase 1 is a kill-all-marked-fighters gate -- fighters, not the turrets every run killed almost exclusively. Phase 2 is positional and ends when the CALIBAN reaches a safe zone, so "what advances a phase" never had a single answer. It also closes a loop to the first session. The hints say red mission markers [OB] indicate your targets, so REMAINING OB -- the HUD counter hunted in the earliest iterations and located at 0xbdb59668 -- is the count of remaining marked objective targets, which is phase-1 progress itself. The old reframing that the counter is not a roster was right, and this names what it is. It is also the correct signal to watch for an advance: not deployed, which only changes once the next phase deploys, but REMAINING OB reaching zero, which is the cause. Method lesson recorded because the reflex will recur: localization.rs has had objectives, hints and lose_conditions for some time, and several iterations were spent reconstructing the same information by hand from SUBObjective strings and the guide script. The reconstruction was not wasted -- it produced the IXUD UTF-16BE and language\ prefix findings independently -- but the corpus should have been searched before the disc was, and grep -rl TextIndex crates/ would have saved the detour. Minor discrepancy noted, not investigated: ixud.rs documents the string pool as UTF-16BE and localization.rs as UTF-16LE.

//! Per-phase MAIN objectives, straight from the localisation index.

|
//! The mission-phase work went looking for what a phase asks the player to do
|
|
//! and reconstructed it from `SUBObjective_local_string.tbl` — the *bonus*
|
|
//! objectives — plus the guide script. `TextIndex` already indexes the main
|
|
//! ones under `S<NN>_P<n>_Objective_<i>`, so this pins them as a disc test and
|
|
//! makes the per-phase goals a checkable artifact rather than an inference.
