Phase-1 live-DB investigation found the connect-time burst (ADR-018) fires
but delivers a weak first impression: pure newest-first selection picks junk
(a livestream + regional news for pilot user Jonte), and all burst summaries
run on the weak koala/phi4-mini instead of the validated iguana/gemma4-26b.
Cached-first was investigated and rejected — ~3% cross-user overlap, 0
cached-and-unsummarized, newest-20 all uncached (newest-first and cached-first
are structurally incompatible).
ADR-028 records: persist duration_s at discovery (ADR-023 already fetches it,
just stops discarding), junk-avoiding burst selection (drop known too-short/
too-long), and a stronger burst-only summarizer chain. Not a throughput change.
