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=="".
Per gogobee_class_balance.md §5 Phase 0: harness skeleton, equipment
and spell-selection policies, Fighter-vs-Mage plausibility run before
Phase 1 generalizes to the full 10 × 30 matrix.
Bypassed in Phase 0 (per doc §2): DB-touching layers (magic items,
armed abilities, pending-cast persistence), subclass passives (none
below L5), and race passives beyond Human +1-all. Everything else
flows through the production combat path.
Initial numbers (400 trials/cell, dungeon T1..T5):
fighter L1 .998 .805 .165 .020 .000
fighter L3 1.000 .998 .795 .235 .035
mage L1 .880 .190 .003 .000 .000
mage L3 1.000 .950 .158 .003 .000
Both classes win at T1 (spell policy is firing — Magic Missile lands
each Mage fight); both collapse by their off-tier — monster scaling
works. The Mage's L1 T2 gap (-60pp vs Fighter) is real data, not a
broken harness. Phase 1 picks up the full matrix from here.
