# PRESSING PLANT — the engine editor / prompt assembler (spec for build)

The tool that turns "describe an idea" into consistent Flow clips wired into a
playable game. One editor, many game projects (Record Store Guy, Beyond Morp:
The Movie: The Game, ...). Name: a pressing plant is where records get made.

## Architecture (match house style: zero-build, stdlib only)
- `editor/server.py` — python3 stdlib HTTP server. Static-serves `editor/` UI +
  the active project dir, plus JSON API:
  - `GET  /api/projects` — list projects (see registry below)
  - `GET  /api/project/<name>/<path>` / `POST .../save` — read/write JSON + files
    inside that project only (path-traversal guarded, `.json`/`.md`/media only)
  - `POST /api/llm` — proxy to LLM for the assistant (see LLM section; keeps keys
    server-side, avoids CORS)
  - `POST /api/flux` — submit a still to MODELBEAST `flux_local` and poll (uses
    MB_TOKEN from env/.env on disk; concept art + ingredient stills stay free)
  - `POST /api/clip` — accept an uploaded/downloaded Flow clip, run ffmpeg
    normalize (tools/postprocess.sh behaviour inline: 1280x720/24fps/h264+aac,
    +faststart), store to `engine/clips/<scene>_<kind>.mp4`, return duration
- `editor/index.html` + `editor.js` + `editor.css` — vanilla SPA, tabs below.
  Reuses the game's arcade styling language so it feels like one product.

## Project registry
`projects.json` at repo root: `{ "recordstoreguy": ".", "beyondmorp": "../beyondmorp" }`.
A project dir must contain: `production/prompts/{blocks.json,looks/,shots/}`,
`engine/scenes.json`, `engine/clips/`, `bible/concept/`. `POST /api/projects/new`
scaffolds that tree (this is how beyondmorp gets born; its seeder — see BEYONDMORP.md
— imports morpquest room JSONs into location blocks).

## Tabs (build in this order — each is independently useful)

### 1. Cast & Places (blocks.json editor)
Card grid of characters and locations/sets. Each card: name, the verbatim prompt
block (textarea), and attached reference images (from `bible/concept/`, displayed;
"Generate still" button → `/api/flux` with the block + chosen look via promptc
logic; "this is the Flow ingredient" checkbox per look — tracks which ingredient
stills exist per look, warns when a shot uses a character with no ingredient for
the active look). Images can also be dragged IN (John's own refs/sketches) — they
become inputs: "Describe this into a block" button sends the image to the LLM
(vision-capable route) to draft the prompt block.

### 2. Map (story graph)
Node canvas (drag boxes, draw arrows — SVG, no lib): nodes = scenes, arrows =
onSuccess flow; death branches implicit. Node color = status: idea → shot-spec'd →
generated → inserted → tuned. This IS the game's structure editor: saving writes
both `map.json` (positions) and the scene skeletons into `engine/scenes.json`.
Adventure-game projects (beyondmorp) can import an existing room map as the
starting graph.

### 3. Shot desk (the assembler — the heart)
Left: shot list (from `production/prompts/shots/`). Middle: the shot JSON as a
form (world, set, characters, action sentence, camera, duration, qte windows,
kind action|death, notes). Right, live-updating:
- **Compiled Flow prompt** for the active look (port promptc.py's compile to JS —
  same blocks, identical output; keep promptc.py the CLI twin)
- **Flow checklist**: which ingredient stills to attach (by name, with thumbnails),
  Veo tier to use (fast/quality per shot flag), "copy prompt" button, and a
  "log gen" mini-form that appends to `production/SHOTLOG.csv` (scene, take,
  credits, verdict) so the budget ledger stays honest without leaving the editor.
- Alt-look preview: dropdown re-compiles the same shot in any look.

### 4. Ingest & QTE tuner
Drop a downloaded Flow clip onto a shot → `/api/clip` normalizes + names + wires it
into scenes.json → embedded `<video>` opens with the SAME debug timeline the engine
has (share that code): scrub, frame-step, then *click-drag on the timeline to
paint each QTE window*; pick input direction per window; set per-scene `cueLead`
(the flash-before-window; engine default CUE_LEAD, expose 0–0.5s) and per-window
`cue` on/off. "Test" button opens the real engine at that scene (`?debug=1&scene=`
— add that query param to player.js). This tab is where "insert the clips" happens.

### 5. Writers' room (LLM assist)
Chat panel with the project loaded as context (blocks.json + WORLDS/BEYONDMORP doc
+ shot list). Modes, each returning STRICT JSON the UI applies as a diff-preview
(nothing auto-saves; John approves each):
- "draft shots for this beat" → shot JSONs (action sentence, camera, windows guess)
- "draft a character/location block" (from text OR an attached image)
- "punch up deaths" → death-shot variants for a scene
LLM routing in server.py: default tailnet Ollama `http://100.69.21.128:11434/v1`
(qwen2.5:7b, free, fine for drafts); optional `ANTHROPIC_API_KEY` from .env for a
"quality pass" button (claude-sonnet-5; vision for image→block). Prompt templates
live in `editor/prompts/*.md` so John can tune the assistant's taste without code.

## Consistency contract (why this produces coherent video)
Shots never contain style or character text — only ids. The compiler injects the
verbatim blocks; the checklist pins which ingredient stills accompany the prompt
into Flow. One place to edit a character; every future prompt inherits it. Looks
stay swappable per RSG's system. The editor enforces: no compile if a referenced
character/set id is missing; warn if ingredient still absent for active look.

## Flow reality check (no API)
Google Flow has no public API — generation stays manual in the browser. The editor
optimizes the human loop to: copy prompt → attach listed ingredients → gen →
download → drop file on shot. Everything else (spec, compile, log, normalize,
insert, tune, test) is automated. If Flow ever exposes an API, `/api/flow` slots in
next to `/api/flux`.

## Build order for Opus
1. server.py (static + save + project registry) — 2h
2. Shot desk with JS compiler + copy button (immediately useful for Phase 3 style test) — first
3. Cast & Places (+ /api/flux once MB_TOKEN is sorted)
4. Ingest & QTE tuner (share engine debug code; add ?scene= to player.js)
5. Map; 6. Writers' room (Ollama first, Claude optional)
Definition of done per tab: round-trips real recordstoreguy project files with no
hand-editing needed for the Phase 3 style test and Phase 5 production loop.
