Resolving symbol-table-2 indices turns the bytecode into mission logic. At
0xF524 Stage02.ssb polls unit_state on ADN110, ADN111 and ADN112, updates each
one's objective marker, then latches set_flag(8) -- exactly the
trigger/predicate/set_flag/END_PHASE shape predicted from the disassembly, now
observed in the mission's own code with names the roster tables already gave.
The 12 END_PHASE sites are outro sequences (wait_cmds_drained / fade_sound(3) /
builtin85(3) / wait_s(3) / END_PHASE / yield) -- the terminator, not the
decision.
Fixes a decode bug that hid every argument: the tracker only followed
local[i] = special[0], but the common form is an immediate written straight into
local[i] (k=01,03), so every unit predicate printed with NO arguments. The
disassembly looked complete while being empty exactly where it mattered.
Also records the live probe result: the phase mirror at [*(0x828F35F8)+236]
stayed 0 for ~530s of actively-hunting flight, no advance observed -- which is
what the static analysis predicts for phase 1, since ChangePhase only posts once
the ordinal exceeds 1.
Table at 0x8227226C is 147 big-endian absolute VAs (verified structurally: it
ends exactly where the first handler begins, all targets inside sub_82272220).
Arguments are not in the instruction -- every handler does c_str() on
[phase+20], a packed blob, which is what the local[] staging fills. Return 2 =
yield; five built-ins block by skipping the pc advance.
Recovered the ScriptPhase state layout: 32-entry float and flag register files,
int/double result registers, the timer block, and the runtime unit array at
+324 indexed by symbol-table-2 index -- a direct hook from bytecode call sites
to the two .ssb symbol tables.
Spot-checked two claims against the disassembly rather than trusting them: id 4
loads a DOUBLE into the thread countdown and returns 2 (wait_s), and id 24 reads
current/initial squadron member counts (squad_survival_pct). Both exact.
Counting Stage02.ssb: unit_state 255, hp_pct_test 167, dist_lt 92, unit_alive
71, unit_relation 52 -- and squad_survival_pct, group_ratio_pct and the two
global counters are NOT called at all. So Stage 02's phases are gated on named
units (destroyed / HP / proximity), never on an aggregate count, even though the
kill-counter primitives exist in the VM. That answers the standing 'next wave
after N kills or after an event?' question for this stage: specific units, not a
number.
isl.py now names the built-ins, so the run-up to the first END_PHASE reads
wait_cmds_drained / fade_sound(3) / builtin85(3) / wait_s(3) / END_PHASE.
Not settled: 3 handlers unresolved (55, 75, 105); the 1024-slot interpreter
command table is only partly recovered.
