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 +# from the afterlife checkout (a uv project; scipy is an optional extra there) +cd /path/to/afterlife +uv run --with scipy python /path/to/scripts/parity.py . > /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.py` refuses to run without scipy: `life.py` quietly turns its census +off without it, and the recording would be of the wrong universe. Recording +takes about two minutes, and so does the replay. + +`parity` replays 22 cases, in three kinds: + +- **still** (16): `life.py`'s `InfiniteLife` from a seeded genesis with the + dice taken out, so the physics and every read-out are deterministic. Nine + seeds; tiny, absurdly tiny, odd and 1080p terminals; travellers crossing + every seam of the torus; haunted mode; pan, zoom, toggle, focus and home; + and resizes, where a new world adopts the old one. +- **live** (4): the dice stay in. `life.py`'s `random` and `np.random` are + swapped for one mulberry32 stream that the port draws from too. Genesis, + every injection, a garden at generation 5000, and on-cue provokes and + collisions then have to draw the same numbers in the same order. One thing + is pinned: `_find_quiet_spot` orders tied scores by + `np.argpartition`, which is numpy's implementation detail, so the live + cases give it a stable sort, as the port uses. +- **focus** (2): hundreds of small worlds of stamped clumps, for + `auto_focus`'s hotspot (scipy's `uniform_filter` breaks exact ties by its + own rounding, and the port reproduces it) and its percentiles. + +Every step is checked: population, pop floor, spread, cycle detection, engine +events, camera, auto-zoom, mood, time dilation, the activity centroid, a +checksum of every age, the smoothed ages and activity, the display maps every +seventh step, the census and its sites every 150, and, in live cases, the +draw count. At the end it checks the final ages, the display maps at all five +zooms, the sparkline, the epoch and auto-focus. 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.
