The agreed design for the spell system (epic #36, Vulgare Arcano), produced by running the game-design skill: a multi-round interview + a 4-lens critical panel (new-player, exploiter, coherence/server-authority, client UX).

docs/game-design/systems/spell-system.md — the full design: a real-time incantation mind-game (speak spells word by word, in public; read/predict/bluff the opponent). Key decisions after the panel: server-paced word emission (no client can rush the tell), fire-bolt-harder + shield-absorbs-any (fixes the water-dominates-fire RPS hole), 3-word silence interrupt, legend + practice-mode onboarding, and a raft of coherence fixes (range ≤ AoI, own message channel not chat, SpellSystem component, cast-walk via the movement component / HARD GATE, Magery skill).
docs/game-design/vision.md — a designed-not-built pointer.

No code. The player-observable Definition of Done is in the doc; the technical breakdown is a separate review (to be filed against #36).

First output of the game-design skill: an interview + a 4-lens critical panel
(new-player, exploiter, coherence/server-authority, client UX) produced an agreed
design for a real-time incantation mind-game — speak spells word by word, in public,
read/bluff your opponent. Server-paced word emission, fire-harder + shield-absorbs-any
(RPS fix), 3-word silence interrupt, legend + practice-mode onboarding. Design doc under
docs/game-design/systems/; bible updated with a designed-not-built pointer.
