Descriptor + pure adapter + host tests for the per-player turn driver. Not
deployed; the WIN32 half is unbuilt here (no cross-compiler on this host).
The declared boundary is narrower than the function on purpose. Phases 2, 3
and 6 -- the savings apply, the aid records and the research refund -- are pure
functions of ComputeBudget's 22 slots and ProcessResearch's overBudget, and
both live in the original's own stack frame. Reaching them would mean calling
ComputeBudget ourselves (it repairs ships in orbit, audit #6), reading the
nested B1/B3 hooks (audit #5, the self-fulfilling compare), or inferring them
from the Sav delta. So they are guarded, not checked, and the three formulas
are written and unit-tested but not wired into the verdict.
Declared: the phase-7 clear, the RebAI decay, the descending timed-bonus
sweep, plus roll_flags and rng as observations ours never writes. Guards over
the whole ServerPlayer and the TechTree header.
docs/T-turn-driver.md states, before any run: which regions must not diverge,
which checks are weak by construction on the reference save, what falsifies
the ResearchRollPending reading, and the save that would finally fire the
branch nobody has seen.
host ctest 36/36 (was 35/35); clean_room_check OK.
