32px strip in the bottomticker grid-area that renders the ticker Zustand
store as a horizontally scrolling marquee — one of the few places motion
is allowed because new entries pushing older ones along IS data changing.
Source label uppercase + letter-spaced --fg-3, headline body --fg-2,
relative timestamp mono tabular --fg-3.
Empty state is a bare strip (no "no events" message, no illustration) —
operator UI doesn't onboard. The track only renders when items.length > 0
so the marquee animation isn't running over an empty list.
formatRel uses module-scope SECONDS_PER_MINUTE / SECONDS_PER_HOUR /
MS_PER_SECOND constants (no inline magic numbers). Animation uses kebab
keyframe name (stylelint keyframes-name-pattern).
The only surface in the dashboard that uses amber as a fill color — the
one-alarm-color rule reserves this paint for "look here." 48px strip in
the alertbanner grid-area, dark text (--amber-fg #1a1a1a) on the amber
fill for cross-room legibility, ellipsis on long messages, dismiss button
at right. Returns null when the ui store has no currentAlert so the row
collapses to zero and the center grid sits flush with the top strip.
Auto-dismiss after 30s via setTimeout in useEffect; cleanup on unmount
or alert change. role="alert" for screen readers. focus-visible outline
1px --amber-fg.
Adds --amber-fg to ethos tokens — pairs explicitly with --amber so any
future amber-fill surface uses the same dark text. Also cleans up an
empty `//` line in the ethos comment block (stylelint scss/comment-no-empty).
Thin 36px strip in the topstrip grid-area: left = MONITORING THE SITUATION
label + about-trigger icon, center = HH:MM:SS UTC mono clock with tabular-nums
ticking once per second, right = settings gear (auth) or user (anonymous)
that navigates via ROUTES.{SETTINGS,LOGIN}. About icon dispatches openAbout
on the ui store; the modal itself is Task 23.
Pure monochrome — title --fg-2 letter-spaced uppercase --type-label, clock
--fg-2 mono, icons --fg-3 with --fg-1 hover color shift (no transition,
no scale, no rounded surface). Reads tmux-status-line, not SaaS app header.
focus-visible outline 1px --fg-2 for keyboard a11y. Dashboard.tsx renders
<TopStrip /> as a direct child of .root so it auto-places into the
topstrip named area.
Plan 5 Task 8 Design QA: strip height, label tier, mono tabular clock,
zero rounding, tmux feel — all verified.
Replaces the demolition scaffold with the structural grid that Tasks 8-21
fill in. Root is a 4-row grid (topstrip / alertbanner / main / bottomticker)
with named grid-areas; the main row contains a 3-col sub-grid (left aside /
center section / right aside) at fixed 320px / 1fr / 320px. 100dvh, no body
scroll, ethos custom properties only — no template SCSS variables touched.
Adds --col-panel-width: 320px to the ethos token block (no magic number in
the layout module). index.tsx becomes a one-line re-export of Dashboard so
the lazy-route contract in routers.tsx stays unchanged.
No placeholder components. The empty <aside>/<section> elements are the
column containers themselves; subsequent tasks add real children inside
them rather than swap stub components.
Verified in browser at 1920x1080: rgb(10,10,10) bg, 320/1247/320 col rects,
1px var(--fg-4) rules between columns, body has no scroll. All 5 Plan 5
Task 7 Design QA boxes checked.
Two related issues caught in live verification:
1. Coinbase's sequence_num is connection-global (not per-product). Previous
per-product tracking flagged every cross-product frame as a gap.
2. Even after switching to global tracking, gaps still occur regularly under
normal operation (Coinbase's exact sequencing pattern across channels is
not strictly seq+1 frame-to-frame). Treating gaps as fatal kills the
ReadLoop in seconds, never giving the minute aggregator a chance to cross
a boundary, so btc_eth_minute stays empty.
Resolution: rewrite Sequencer for a single global counter and downgrade
gap-detection to a non-fatal Warn. ReadLoop continues; (symbol, ts) PK on
btc_eth_ticks is the safety net for any duplicate replay. Includes a
diagnostic log on loop exit (handleConn) for ops visibility.
Coinbase Advanced Trade WS leaks Go's time.Time.String() format in
heartbeat events (e.g. "2026-05-02 07:55:50.784... +0000 UTC m=+102632...")
which is not RFC 3339 — UnmarshalJSON into time.Time fails and the entire
envelope errors. Decode current_time as a string and parse it with a
fallback that handles both RFC 3339 and the Go-string variant (with the
m=+monotonic suffix stripped).
Adds shopspring/decimal as a require (folded with the first consuming task per
Plan 2 convention). cenkalti/backoff/v4 is also now consumed transitively;
remains indirect until Task 5 (reconnect) imports it.
Hand-crafted fixture matches spec §8.5 schema. Live API endpoint may move; client
takes BaseURL config for swap-in once api.ransomware.live publishes a stable JSON
endpoint (current free tier returns HTML landing page on /recentvictims).
