Generalizes the Phase 0 spike harness to the full build matrix the
class-balance doc plans for. No tuning yet — just measurement.
- classBalanceProfile gains Subclass; buildHarnessCharacter sets it on
the synthetic DnDCharacter; buildHarnessPlayer now calls
applySubclassPassives after class+race passives, matching live order
(combat_bridge.go, combat_session_build.go). Subclass="" is a no-op,
so L1–L4 pre-unlock rows are unaffected.
- buildPhase1Profiles yields 190 rows: 10 classes × 4 pre-subclass
levels (L1–L4) + 10 classes × 3 subclasses × 5 post-unlock checkpoints
(L5/7/10/15/20). Order is registry order so output reads like the
design doc / !class help.
- TestClassBalance_Phase1_FullMatrix runs the matrix at 200 trials/cell
(~5.5s) and logs every cell plus a per-class tier-mean summary with
min/max range. Only harness-broken pathologies fail the test (0% at
T1 anywhere, or 100% at T5 for an L1 build); per-tier parity bands
land in Phase 2 once we have data to calibrate the tolerance.
Phase-2 baseline from this run: at T4 the cross-class spread of mean
win rate runs Bard 0.62 → Fighter 0.80 (~18pp); at T5 0.48 → 0.64
(~16pp); casters trail martials at the post-unlock tier (T3) by ~20pp.
Phase 0 test (TestClassBalance_Phase0_FighterVsMage) still green with
identical numbers — the additional applySubclassPassives call is a
no-op for Subclass=="".
Phased plan for the class-balance pass. Unlike the race pass, classes
are *measured* not modeled: combat is one-shot auto-resolved through a
seedable simulateCombatWithRNG, so the harness runs Monte Carlo over the
real engine and reads win rates directly.
Scopes the full matrix (10 classes × 30 subclasses × level checkpoints ×
monster tiers), the two hard policies to de-risk in Phase 0 (equipment
loadout, spell selection), the per-tier win-rate parity rule, and the
tuning levers. Phase 0 spike in progress.
