Milestone: M4 — the product UI and the container delivery (Kind: feature)
Change: m4-ui-and-container-delivery
Branch: feat/m4-ui-and-container-delivery
Layer: SBHOST — the real binary serving the Kotlin/JS + React terminal over a live ClickHouse store, driven by a real headless chromium
Verdict: the terminal is delivered and its user stories are captured and checked; the container image's build/run is not run on this host — the podman-kind runner carries no engine client (preinstall#114).

What was done, in short

The product's UI is a browser terminal. A Kotlin/JS module (ui/) renders React through kotlin-react/kotlin-react-dom, its graph is owned by Koin (koin-core-js), and it charts the recorded price series with the free TradingView lightweight-charts (Apache-2.0).
The terminal reads the product's own read API — GET /api/health, /api/events, /api/event/<slug> — served over the same CollectionStore/MomentQuery reads the collector uses. Read-only by construction; no order path.
A dead store is reported, not hidden — an explicit store unreachable state, not an empty list.
The product ships as one container image. Containerfile is multistage: the Kotlin distribution and the terminal's bundle, a JRE, and the pinned ClickHouse 26.9.12.8. The snap is retired (owner's decision, 2026-10-09).
The terminal was captured and checked, on a real browser, against the store's own rows. 10 frames, 38 field-for-field checks, all matching, user-verify-m4: OK.
The acceptance found and fixed three real defects the offline tests could not see — the read-API GET that never reached the browser, the empty /api/event answer, and the chart that never drew. Detail below the stories.
Each frame is asserted twice — the page must carry the fact (DOM checked before the shot) and the capture must have painted (non-white fraction checked after it). A frame that fails either is not evidence.

The three defects the acceptance caught (and the offline tests did not)

The terminal's own jsNodeTest suite was green the whole time; it drives the components with a fake read API. Only driving the real bundle in a real browser against a real store exposed these:

The read-API GET never reached the browser. Bridge.kt declared httpGet as @JsModule("./http.js") @JsNonModule; the Kotlin/JS UMD rule then binds the module namespace object, and the bundle called that object as a function — TypeError: t is not a function, and the terminal sat in store: unreachable while /api/health on the same origin answered {"reachable":true}. Fixed by inlining the same-origin GET and leaving no relative JS-module seam but the chart's.
/api/event/<slug> answered nothing. The price series was read with a sentinel Long.MAX_VALUE/2 window; the upper bound lands in the year 292278994, ClickHouse rejects the DateTime64 (HTTP 400), and the throw escaped the handler as an empty reply. Fixed by reading the series over the store's real recorded span, and by picking a token the store actually recorded rows for.
The chart never drew, then drew Invalid Date. renderChart was declared but called from nowhere, and lightweight-charts was absent from the bundle (an ES export behind the same UMD binding). Once wired, the series handed it a boxed Kotlin/JS Long and a locale of en-US@posix (Chromium on a LANG=C host), which threw inside the time axis. Fixed by a CommonJS chart bridge with a dynamic import() (the package is ESM-only), integer-seconds series points, and an explicit localization.locale.

User story 1 — "I open the terminal and see what has been collected"

An owner opens the terminal and wants to know, at a glance, which events the collector has recorded and how much of each: the events with their market and token counts, the number of order-book and trade rows, the recorded time span, and a filter that narrows the list to a slug.

the terminal's events panel — the collected events, their markets, tokens, both counts and the recorded span (header: store up, events 4/4)

the counts table — val-nrg-loud 10 order-book / 5 trade rows; the three others 2 / 1

the recorded span — the min and max recv_time across both tables

the filter narrows the list — the chosen event's leading token keeps it and drops the rest (events 1/4)

Against the store: list.order_book rows == store and list.trade rows == store for all four events (2=2, 1=1, 10=10, 5=5); the filter narrows 4 → 1. match.

User story 2 — "I pick an event and see its recorded price series, the book and the trades at a moment"

The owner picks an event and a moment T and wants the recorded price series, the order book that stood then and the trades that executed around it. The view names the event, the moment and the window, so the moment is recountable by hand.

the event view at T — the chart of the recorded series, the event name, the moment T (2026-10-10T08:34:25.889Z) and the window (±10s), then the two tables

the price chart — the recorded series over the recorded span, drawn with lightweight-charts; the layer samples the canvas itself (1839 series-coloured pixels, 53 distinct colours)

the order book at T — best_bid 0.57, best_ask 0.58

the trades around T — the ±10 s window, in receive-time order (3 rows)

Against the store: orderbook.at_T best_bid == store → 0.57=0.57; best_ask → 0.58=0.58; trades.around_T count == store → 3=3; chart series points == store trades over the span → 5=5. match.

User story 3 — "I can trust what the terminal shows me"

An owner has to be able to tell "the store did not answer" from "the store is empty". The terminal renders each as its own state; the layer captures each and asserts the page says so.

the store unreachable — an explicit state, not an empty list: 'nothing is shown rather than an empty success'

a reachable but empty store — events 0/0, span: n/a — a different fact, rendered as such

Goal → case → what was observed → result

Goal	The case	What the run observed	Result
The terminal serves the collected events — markets, tokens, order-book and trade counts and the recorded span — and narrows the list by a filter	the terminal's events panel beside a query of the store for the same events and counts	frames 1–4; `list.order_book rows == store` and `list.trade rows == store` for all four events (2=2, 1=1, 10=10, 5=5); the filter narrows 4→1	OK, captured and checked
For a chosen event the terminal charts the recorded price series and shows the order book at a moment T and the trades around T, read from the store	the terminal's event view at T beside the store's own rows at T	frames 5–8; the chart's canvas carries 1839 series pixels; `best_bid` 0.57=0.57, `best_ask` 0.58=0.58, trades around T 3=3, series 5=5	OK, captured and checked
The terminal reports its store honestly — a dead store is not an empty success	the terminal against a dead store and an empty store	frames 9–10, each asserted for its own state	OK, captured and checked
The product ships as one container image carrying all of its dependencies, and is built and run as an image	`./run-m4.sh deploy` on a clean environment (`podman build` → `podman run`)	not run — the `podman` layer carries no engine client (`have podman MISSING`, preinstall#114); the `Containerfile`'s static checks pass in `./gradlew test`	open
The snap is retired	no `snap/snapcraft.yaml`, no snap scenario, no snap path in scripts or workflows	grep for the snap paths is empty; the REMOVED delta sits in the change	OK

The reverse runs — a green result turned red

Each check must go red on its own broken subject. All were run from the same script as the green run, each pointing it at a deliberately wrong subject (so no subject is mutated in place).

Reverse run	What was broken	What went red
reverse-a	the layer pointed at the readable fallback page instead of the terminal	32 mismatches, `user-verify-m4: FAIL` — the page is not the terminal (`class="terminal"` absent), and its events do not carry the terminal's rows or chart
reverse-b	the reference store is a different database than the terminal reads	20 mismatches, `user-verify-m4: FAIL` — the terminal's rows, span and book do not match the reference the layer reads
reverse-c	the terminal is served by a product whose store does not answer	12 mismatches, `user-verify-m4: FAIL` — the terminal lists 0 events where the store has rows for 4

Layers

SBHOST — this run: the terminal (the Kotlin/JS + React bundle) served by the real binary against a live ClickHouse store, driven by a real headless chromium; the frames are the layer's own.
CIHOST (the podman layer) — the image's build and run: open, blocked by the engine-client gap (preinstall#114); the yc lens the M3 record names is deferred (polymarket#11).

What this run does not cover

The container image's own build and run — the podman layer carries no engine client (have podman MISSING, preinstall#114).
The milestone's CIHOST (yc VM) run — deferred, blocked by the YC quota (polymarket#11).
This page is a report of the run's raw evidence, not the product itself.
