The ski race is neither. +- A streaming-numbers demo is the one shape where *every* grid looks good. It + does not showcase Pretable's wedge: **wrapped text + variable row heights**. + +We want a single example that is (a) instantly credible, (b) natively +streaming, and (c) proves the wrapped-text/variable-height wedge — so the demo +earns the "built for the AI era" claim instead of asserting it. + +## Decision + +Replace the ski-racing hero with a **buy-side portfolio-manager (PMS) +cockpit**: a live positions grid that does two things at once. + +1. **Numbers tick.** Prices and P&L update at high frequency and flash + green/red — the most recognizable, credible streaming demo on the web + (this is AG Grid's flagship blotter). Proves speed/streaming. +2. **An agent writes.** An **AI Analyst** column streams wrapped commentary + per holding (risk flags, news-driven rationale, rebalance suggestions), + token-by-token.

Rejected. +- **Agent-builds-a-table on docs/evals/research/support:** strong AI story but + less instantly credible and less visually striking than live finance. +- **Keep ski racing:** contrived; mountain metaphor doesn't map to any buyer. + +## Architecture + +The current hero already implements exactly the engine we need; we repurpose +it rather than rebuild. Today's flow (`app/components/heroGrid/`): + +- **Phase 1 — element stream.** An LLM-style token stream + (`response.output_text.delta` deltas carrying JSON) is parsed by + `parseElementStream` from `@pretable/stream-adapter` to emit initial rows. +- **Phase 2 — rAF virtual clock.** Timestamped `update`/`rerank`/`commentary` + events are drained on a `requestAnimationFrame` loop and applied as row + patches. A rate tier (10/60/250) gates event types and telemetry density. +- **Telemetry.** `useFrameStats` measures real `fps` / `p95` from rAF deltas; + `TopControlBar` displays them. `Scoreboard` is a derived sidebar. + +PMS maps onto this directly: Phase 1 assembles the book; Phase 2 `tick` events +drive price flashes; Phase 2 `commentary` events stream the analyst text. + +### Data model — `PositionRow` (replaces `RaceRow`) + +```ts +interface PositionRow extends Record { + id: string; // ticker, stable row id + symbol: string; // "NVDA" + name: string; // "NVIDIA Corp" + qty: number; // shares held + last: number; // live price; flashes on update + mktValue: number; // derived qty * last; live + dayPnl: number; // signed day P&L; live + dayPnlPct: number; // signed day P&L %; live + weight: number; // % of NAV; live-ish + sector: string; // for allocation rollup + analyst: string; // AI commentary; streams token-by-token; multiline + flag: "trim" | "hold" | "watch" | "risk"; // severity pill; may change live +} +``` + +### Streaming recording (deterministic, committed, offline) + +No LLM calls at runtime. A generator script produces a committed recording the +replay engine plays back — same pattern as `generate-race.ts` → +`recordings/race.{jsonl,ts}`. + +- **Phase 1 — book assembles.** Positions stream in as an element stream + ("the agent builds the book"). Visible buffer ~30–40 rows; framed as a slice + of a larger book (e.g. "142 positions"). +- **Phase 2 events:** + - `tick` — high-frequency price update; patches `last`/`mktValue`/`dayPnl`/ + `dayPnlPct`/`weight`; drives the flash animation. This is the speed proof + and the dominant event volume. + - `commentary` — token deltas appended to a row's `analyst` field, producing + the "typing" effect and variable row heights. This is the wedge proof. + - `flag` / `rerank` — occasional severity change and/or re-sort. +- **Generation:** `scripts/generate-portfolio.ts` with a **fixed seed** so the + recording is deterministic and testable. Uses **real tickers** (public + facts). A subtle disclaimer — "Illustrative, synthetic data — not investment + advice" — appears in the control bar / footer of the demo. +- **Rate tiers:** keep the 3-step control mechanism; relabel to a `ticks/s` + envelope. Tiers gate tick density (and optionally commentary density), not + playback speed — consistent with the current engine's semantics. + +### Sorting + +`sort.ts` provides comparators: + +- Numeric: `qty`, `last`, `mktValue`, `dayPnl`, `dayPnlPct`, `weight`. +- Text: `symbol`, `name`, `sector`. +- `analyst` not user-sortable; `flag` optionally sortable by severity. +- **Default sort:** `weight` desc (largest positions first).

Nothing in `packages/*` changes. +- **The replay engine has two phases** (`replay-engine.ts`): + - *Phase 1*: lines of `{"type":"response.output_text.delta","delta":"..."}` are concatenated and fed to `parseElementStream()`, which yields complete row objects as the JSON array parses. Each yielded row becomes an `add` transaction. + - *Phase 2*: lines of `{"type":"update"|"rerank"|"commentary","t":,"patches":[{id,...}]}` are sorted by `t` and drained on a `requestAnimationFrame` virtual clock. Each becomes an `update` transaction (array of partial rows keyed by `id`). + - A rate tier (`10 | 60 | 250`) gates which Phase-2 event types fire and (at 250) synthesizes extra rows. We keep the tier mechanism, repurposed for tick density. +- **The recording is committed twice**: `recordings/.jsonl` (source of truth) and `recordings/.ts` (a `export const ... = ""` wrapper, because Turbopack rejects `?raw` .jsonl imports). Both are emitted by the generator script's CLI block. +- **Column API** (`@pretable/react`): `{ id, header?, wrap?, widthPx?, pinned?: "left", sortable?, value?: (row)=>unknown, format?: ({value,row,column})=>string, render?: ({value,row,column,formattedValue,rowId,rowIndex,isFocused,isSelected})=>ReactNode }`. Use `render` for the flashing price cell and the wrapped analyst cell. +- **Variable row height** works automatically for `wrap: true` columns: the surface re-measures a row (`measureRenderedRowHeight`) whenever its rendered text content changes. This is why streaming text into a wrapped cell grows the row without manual height bookkeeping. +- **`HeroGrid.tsx` owns local row state.** It receives `add`/`update` transactions from the engine and reduces them into a `PositionRow[]`.

From 3483e037000523251dcb4d88527c95aab57a6773 Mon Sep 17 00:00:00 2001 From: Brian Love Date: Tue, 9 Jun 2026 20:49:03 -0700 Subject: [PATCH 09/54] feat(website): portfolio replay engine (tick/commentary/flag events) Use a -1 sentinel for the virtual-clock baseline instead of overloading 0, so the first real rAF timestamp of 0 (as in tests) isn't mistaken for uninitialized.

A 2,500 × 500 grid must **not** mount until scrolled near, or it taxes +initial load. So each showcase's interactive grid self-gates mounting with its +own `IntersectionObserver` via a small shared `useInView` hook: until the section +is near the viewport, render a fixed-height placeholder (same height as the grid, +to avoid layout shift); once in view, mount the real grid.

Headers `C1 … C500`. A fixed width + (~90px) so 500 columns force horizontal scroll.

The +1.25M figure is conceptual (cells = rows × cols), never allocated. + +### The grid + +A single `>` with `columns`, `rows`, `getRowId`, +`viewportHeight` (a fixed number, e.g. 420), inside a bordered container that +scrolls both axes. **Column virtualization is automatic** — the surface measures +its own width and renders only visible columns (verified: `pretable-surface.tsx` +measures `viewportWidth` internally and feeds it to the render snapshot). Row +virtualization is likewise automatic. No controlled `state` → no +`usePretable` controlled-state warning. + +Columns/rows are created once (`useMemo([], …)`) so the grid instance is stable. + +### The counter (the proof) + +`useRenderedCellCount(scrollViewportRef)` returns the count of +`[data-pretable-cell]` nodes currently in the DOM. Implementation: a ref to the +scroll viewport; on `scroll` (rAF-throttled) and on mount, read +`el.querySelectorAll("[data-pretable-cell]").length`.

(Hand-authored constant; +may borrow shape from the hero's `PositionRow` but does not import the streaming +machinery.) + +### Resize + reorder (uncontrolled) + +The surface's built-in drag interactions handle both: drag a column border to +resize, drag a header to reorder. We run them **uncontrolled** — no `state` +prop — so the grid owns the layout internally and there's no controlled-state +warning. (`copyWithHeaders`/selection not needed here; keep it minimal.) + +**Reset layout** restores defaults by remounting the grid: a `resetKey` state, +bumped on click, used as the React `key` on ``.
