From 1b59453825dce8bfde8c4b76d5ef5badf05e4024 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 29 Sep 2026 20:49:43 +0000 Subject: [PATCH 1/7] afterlife: the game of life, after hours, ported to the web MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit afterlife (LuxiaSL/afterlife), the terminal screensaver, now runs at /afterlife. It is the same program, not an imitation. The engine and the music are method-for-method ports of life.py and life_music.py. The page is drawn as a terminal: half-block cells in the same xterm-256 colours curses used, and a status line where every glyph has its own column. - src/engine: InfiniteLife (step, the infinity engine, the dramaturge, camera, auto-zoom, auto-focus, time dilation, haunted mode), the census (the scipy dilation/label/find_objects it needed, written out), the ticker, and every musing, generated from life.py rather than retyped. - src/music: LifeMusicEngine in an AudioWorklet, rendering the same 2048-frame buffers PyAudio asked for. The worklet is bundled by esbuild and inlined, so there's no second file. - scripts/parity{.py,.ts} replay life.py from a seeded genesis. Every step's population, telemetry, camera, zoom, mood and tempo match exactly, and so do the final ages, the display maps at all five zooms, the census, auto-focus and haunted mode. parity_music matches the original engine sample for sample (worst |Δ| 1.8e-7), including the cadence, the style crossfade and the noise bursts. - The universe persists in localStorage. It is saved on the way out and every 5000 generations, and resumed with "the universe remembers generation N". - Added for the web: a splash to start the sound, a keys panel that runs every key (for phones), drag to draw life, pan and zoom with the pointer and touch, and a two-line status on narrow screens so the ticker keeps its room. oikos gets a tape for it on channel 10. The screen runs afterlife's own engine and renderer, imported from ../afterlife/src, on a 64×24 terminal, and adopts your saved universe if this browser has one. It also has a placement at the end of the floor arc, a pane note and a status line. /afterlife is added to the sitemap and urls.txt, with tests for the page, the committed bundle and the framing headers.

A camera +steers toward the drama. A dramaturge stages collisions and aims gliders at +the citizens it has recognised. A ticker muses. The music scores it all, and +`g` brings back the bug that painted the void magenta. + +It is meant to be the same program, not a tribute. The terminal was the +medium, so the page is a terminal: a canvas drawn as a grid of character +cells. Every cell is an upper-half block in the same xterm-256 colours curses +asked for, and the status line keeps to the grid one glyph per column. + +## Faithful, and how we know + +The engine (`src/engine/`) and the music (`src/music/engine.ts`) are +method-for-method ports of `life.py` and `life_music.py`. Two scripts replay +the Python original and compare the results: + +```bash +# needs the afterlife checkout and a Python with numpy + scipy +python scripts/parity.py /path/to/afterlife > /tmp/parity.json +npm run parity -- /tmp/parity.json # "the same universe ✓" + +python scripts/parity_music.py /path/to/afterlife > /tmp/music.json +npm run parity-music -- /tmp/music.json # "the same music ✓" +``` + +`parity` seeds `life.py`'s `InfiniteLife` and takes out the dice (the +injections are the only randomness a replay can't share). Then it checks the +port step by step: population, pop floor, spread, cycle detection, engine +events, camera, auto-zoom, mood and time dilation. At the end it checks the +final ages, the display maps at all five zooms, the census (the original's is +scipy), auto-focus, a pan/zoom, and haunted mode. All of it matches exactly. +`parity-music` feeds both engines the same scripted evening: a boom, a broken +cycle and its cadence, two style crossfades, noise bursts, and epoch roots. +Every sample matches within float32 rounding (worst |Δ| ≈ 2e-7). + +## What changed for the web, and why + +- **The universe lives in localStorage** (`afterlife-universe-v1`), not + `universe.npz`. It is saved when you leave (`pagehide`, or the tab being + hidden) and every 5000 generations, and resumed on the next visit with + *the universe remembers generation N*. Only ages are stored, sparsely (the + grid is exactly `age > 0`), because a save must be synchronous on the way + out. oikos reads the same key, so its screen runs *your* universe. +- **Music waits for a gesture.** Browsers only start sound from a click or a + key, so the splash asks for one. Until then the status line shows no music, + just as the terminal did without PyAudio. The engine runs in an + AudioWorklet at 44.1 kHz and renders the same 2048-frame buffers PyAudio + asked for, because its smoothing constants are per buffer. `vite.config.ts` + bundles the worklet with esbuild and inlines it into the page. +- **`q` leaves**: back where you came from, or to æthera. Inside an oikos + screen it can't leave, and the ticker says so; ⏏ is on the other side of the + glass. **`d`** records snapshots as before and downloads `snapshots.jsonl` + when you stop (`life_music_diag.py --replay` reads it). `life_stats.csv` is + kept in memory and downloads from the keys panel. +- **More than a terminal's mouse.** A click still toggles a cell. You can + also drag to draw life, right-drag or shift-drag to pan, and scroll to zoom. + On touch: tap to toggle, drag to pan, pinch to zoom. The **keys** panel + (`?`) lists every key and runs it on click, for phones. +- **Narrow screens get a two-line status.** On a phone the ticker would lose + its room to the stats and fall back to the terminal's compact line, so the + ticker gets a line of its own instead. The sparkline shortens to fit. +- **Resizing keeps the universe**, as `KEY_RESIZE` did: it is adopted, + centred, into the new world. +- Two display caches are now invalidated on pan, zoom and toggle. In the + terminal, a pan or click made while paused didn't show until you unpaused. + +## Layout + +``` +src/engine/ life.ts (InfiniteLife), census, ticker, musings, constants, persist, stats +src/term/ render.ts (the terminal: grid, status line, stats overlay), palette.ts (xterm-256) +src/music/ engine.ts (LifeMusicEngine), worklet.ts, audio.ts (the page's side) +src/main.ts life.py's main(): the loop, keys, pointer, splash, persistence +scripts/ parity checks, bench.ts (life_bench.py), shot.mjs (headless screenshots) +``` + +The engine and renderer have no DOM dependencies beyond a 2D context, so +oikos imports them directly (`oikos/src/screens/afterlife.ts`). + +## Build + +Like syrinx, apeiron and oikos, the built bundle is committed. The Docker +image never runs npm, so rebuild and commit whenever `src/` changes. Rebuild +oikos too if `src/engine` or `src/term` changed, since it bundles them. + +```bash +npm install +npm run build # → ../aethera/static/afterlife/afterlife.{js,css} +npm run dev # the standalone index.html on :5198 +npm run bench # per-frame cost, headless (240×66 terminal by default) +npm run shot -- out/ [url] # splash, lived, stats, haunted, keys, resume, phone +``` + +`shot` wants Playwright's Chromium.

Subject: [PATCH 2/7] afterlife: saves survive blocked storage and haunted
 mode; the world can keep its size

- persist: localStorage is read inside the try, so a browser that blocks
  site data gets a fresh universe instead of a dead page
- persist: ghosts deeper than GHOST_FRAMES are not written (adopt retires
  them anyway); haunted mode no longer blows the 1.5M cap and fails silently
- persist: generation must be a safe integer
- life: the constructor takes a WorldFloor, so a resize can keep the old
  world and a small screen can run a small one

Subject: [PATCH 3/7] afterlife: the shell keeps the universe whole across
 resizes, tabs and screens

- a resize keeps the old world as the floor (no more cropping) and carries
  the session across: pause, speed, zoom, camera, modes, ticker; a load
  keeps the saved world's size; URL-bar jitter no longer rebuilds
- an oikos screen shows the save but never writes it
- a later universe saved by another tab isn't overwritten
- the loop stops at a 12 ms budget and drops the backlog
- a failed music start closes its context and can be retried; iOS
  'interrupted' resumes on a gesture; playback audio session
- key repeat only for repeatable keys; ? and Escape don't start music;
  Enter/Space on the splash enters; touch splash copy; csv isn't a key;
  recording is capped and says when it caught nothing; drags stay on grid;
  a third finger doesn't paint; pixel-ratio changes refit; reduced motion
