Fidelity blocker 2: VTank's UseArcs is 1=No / 2=AtRange / 3=Yes
(refs/vtank/decompiled/hi.cs:515-538, switch on f3.f("UseArcs")): No
always picks the direct-shape spell, AtRange picks arc only once the
target reaches ArcRange, and Yes always picks arc regardless of
distance. The prior port collapsed this onto CombatSettings.UseArcs
(bool), which can represent No and (an approximation of) AtRange but
has no way to express Yes — a profile with UseArcs=3 could never
actually always-arc, and Capture() had to fudge 1<->3 on save,
which is why UntouchedRoundTripIsByteIdentical needed a NormalizeUseArcs
special case.
- CombatSettings: new UseArcsMode enum (No=1, AtRange=2, Yes=3);
UseArcs is now UseArcsMode (default AtRange, matching the previous
bool default's runtime behavior).
- AttackSpellCatalog.ShouldUseArc implements the real 3-way switch,
replacing the `settings.UseArcs && target.Distance >= settings.ArcRange`
expression at both call sites (Yes now genuinely always arcs).
- VtankSettingsProfileSerializer Apply/Capture "usearcs" cases now
cast directly to/from UseArcsMode instead of the `!= 0` / `? 3 : 1`
bool collapse.
- MossTankPanel GetMetaOption/SetMetaOption "usearcs" now exposes the
raw 1-3 value (ExpressionValue.Number / AsInt32 clamped 1-3),
matching the existing pattern for DebuffEachFirst/DebuffSelectionMethod,
instead of ExpressionValue.Boolean/IsTruthy.
- MossTankProfileStore's JSON DTO field type follows suit (System.Text.Json
already serializes CombatSettings' other enum settings the same way).
- Deleted NormalizeUseArcs from UntouchedRoundTripIsByteIdentical —
the test now asserts full byte-identity with no special case, and
CaptureMatchesDeclaredSettingTypeAndValue (added in the previous
commit) no longer needs to skip "UseArcs".
Verification: reverting to the bool model reproduces exactly one
theory failure (CaptureMatchesDeclaredSettingTypeAndValue("UseArcs"):
expected 1, actual 3) confirming this is the only affected setting;
after this change the full 559-test suite passes with zero special
cases.
