# night_sea Black water on a storm night, seen from a lighthouse: nearly unlit, and rough enough to give the beam back as a spread of light on the swell rather than as a mirrored point.

# Stage The staging slice's own shared surface. `game.Core` is the contract between slices and is frozen; this is the contract between the three files of the staging slice alone. `game.Staging` (the director) writes it. `game.ShaftCam` (the camera) and `game.Beam` (the lamp, the beam and the ship) read it. | table | what it carries | |---|---| | `Stage.cam` | the staged pose and `weight`, how much of it is mixed over the follow; plus `shakeAmp` | | `Stage.camNow` | where the camera actually ended up this frame, written by `game.ShaftCam` after the mix | | `Stage.beam` | the lamp's burn, the sweep, how much of the ship is found, and where the beam's far end stands | | `Stage.sky` | the strike burning right now | | `Stage.cue` | `Stage.cueTo(beat, t, hold)` puts a beat at a named second, and holds it there, so a beat can be looked at without climbing a hundred and twenty metres first | | `Stage.report` | which beat is running and how far into it |

# night_hull A ship's hull seen across black water on a storm night: almost unlit blue-grey, rough, made to read as a silhouette until the beam finds it.

# beam_glow The lighthouse beam's own light, as a surface: a warm additive glow the beam cone wears so the shaft of light reads in the air without writing depth over what stands behind it.

# lantern_warm The small warm emissive of a lantern on a deck or a collar: bright at its own scale, warm, and legible at a distance.

# Core The one table every slice of WICK shares: the constants that define the shaft, the sea and the camera framing, the blackboard the rules write and everyone reads, an event bus, the phase machine's single writer, and the Keeper's script. `local Core = require("game.Core")`. See `/zero/source/design/spec.md`. ## Exports - `Core.SHAFT`, `Core.SEA`, `Core.CAMERA`, `Core.STAGING_TIMEOUT` — the place. - `Core.state` — `phase`, `player {x, y, vx, vy, wall, facing, gripping, grip, alive}`, `height`, `best`, `seaHeight`, `seaRate`, `surged`, `lampLit`, `elapsed`, `kicks`, `run`. - `Core.events.on(name, fn) -> unsubscribe`, `Core.events.emit(name, ...)`, `Core.events.count(name)`. - `Core.setPhase(p)` — called by `game.Climb` only. - `Core.LINES`, `Core.say(id)` — the Keeper's lines; `say` emits `"say"` and `"caption"`. - `Core.heightClimbed()`, `Core.seaGap()`, `Core.resetRun()`, `Core.clamp`, `Core.lerp`.
