Logmon now captures the share diff from ckpool's "Possible block
solve" line preceding the confirmation and attaches it to the
BlockEvent. Persisted as share_diff alongside height/hash/reward
and rendered as a new column in the dashboard block history.
The stratifier can accept a connection and close it without
writing a response during early startup — the refresh loop
then logs 'ckpool poolstats failed: read len: EOF' on every
tick until the stratifier is ready, which is noisy and looks
like a real fault.
- client.Send retries once after 200ms if the server closed
the connection before any bytes were read (io.EOF anywhere
in the wrapped chain).
- Aggregator tracks a ckFailStreak counter: first two
consecutive failures log at DEBUG, third and beyond escalate
to WARN. Successful refreshes reset the streak.
Svelte 5 + Vite + TypeScript dashboard that consumes kamado-api over
REST for the first paint and then subscribes to /api/ws for live
updates. Zero runtime deps beyond svelte itself; plain CSS, no
component library.
Layout:
- Header with brand, WebSocket status badge, chain + height
- PoolOverview: hashrate (1m/5m/1h/24h), miner count, network
hashrate + diff, pool share (ppb), expected time to block, uptime
- BlocksTable: recent solves from the in-memory ring (will be
SQLite-backed in Phase 2b.5)
- BestShares: top-10 workers by bestever, falling back to bestdiff
when the ckpool patch isn't present
- MinersTable: joined view of stratum clients and workers with
user-agent-based hardware detection (Bitaxe, NerdQAxe, Antminer,
...), hashrate, best-round, best-ever, last share
State is a single $state() snapshot store in svelte-runes form;
components read from it via $derived. The store does one initial
REST snapshot fetch, then owns the WebSocket with exponential
backoff reconnects.
Vite dev server on :5173 proxies /api and /api/ws to localhost:8080
so you can run `make ui-dev` alongside `make up` in development.
Production serving (bundled into the Go binary via embed, behind /
on :8080) lands in Phase 4.
