Drives same UI buttons a DM clicks. Exercises:
- campaign + character roster (3 PCs)
- monsters, NPC, add-all, hidden hp toggle
- start combat, 100 rounds of nextTurn
- damage/heal, conditions (stunned), toggle-active
- edit initiative, edit name, remove participant
- pause/resume with reinforcement mid-combat
- damage-to-0 + death saves (x3) + revive
- end combat + confirm
Harness: each phase wrapped in recordAsync try/catch. Failures collected,
reported at end, do NOT abort run. Found no app bugs; selector bugs in harness
fixed (char form ids vs placeholders, encounter row scope via Init: marker,
conditions panel async render, dead-participant damage skip as expected game
state, end-encounter modal title 'End Encounter?' not 'End Combat').
289/289 phases ok. 58 other frontend + 39 shared + 19 ws-contract = 116 total green.
