Theseus 0.0.7: multi-source BNS with continuous delta refresh
The first .bch page now opens with zero user-visible latency and stays fresh
for as long as the browser runs. Four sources conspire in parallel — none of
them can block a navigation:
1. Warm start from disk (sync)
warmFromSnapshot loads the user-cache snapshot first, then falls back to
the copy bundled with the build. sharedIndex is set BEFORE the first
navigation can even fire.
2. Continuous background delta refresh (every 30 s)
startBnsPolling opens one electrum connection, fetches the beacon
history (a single call), and only pulls verbose tx bodies for txids we
don't already have — mergeFreshHistory-style. Merges into memory,
rebuilds the index locally, persists the enlarged snapshot to disk.
Turns a ~60 s full walk into ~1 s per new event.
3. Sia snapshot pull on boot (one-shot, wins the NEXT boot)
refreshSnapshotFromSia downloads the operator's published snapshot from
s3.silentmode.st for the next launch. After a long idle period the
browser resumes from that fresher snapshot instead of walking days of
events.
4. ensureIndex full-walk fallback
Still runs on boot for the case where there's no bundled snapshot AND
the poll hasn't landed yet — very first launch, offline install, etc.
resolveHost now prefers sharedIndex (which the poll keeps live) and, on a
miss with a stale index, triggers pollAndMerge (delta fetch) instead of
ensureIndex (full walk). The old full-walk fallback is only taken if the
delta primitives aren't available (running against an older resolver-web).
Argus/src/lib/resolver-web.js exports connectElectrum so the Theseus poll
can drive its own ad-hoc queries against the pool without duplicating the
Electrum wrapper.
Bundled starter snapshot refreshed: 73 beacon txs, root c37b859682…54e414ba.
