Backlog mediums (display/gating/caching only — no send/sweep/encrypt call or args changed):
Resilience:
- Gate Send/Review on a KNOWN peer-derived tip (SyncInfo::sendTipReady): a fresh reconnect or peerless node
has tip_known=false, so its local height isn't a trustworthy network tip — sending is disabled with a
clear tooltip until it is. Lite is exempt (its own sync gate). The z_sendmany call is untouched.
- History now shows "Dropped" for a conflicted tx (confirmations < 0) and "Expired?" for one unconfirmed
> 1h, instead of "Pending" forever (new TransactionInfo::isConflicted/isStalePending; the tab inlines the
check on its DisplayTx fields).
- A cached z_viewtransaction row's confirmations now advance by the blocks mined since it was sampled
(observed_height), instead of freezing at the cached value; never goes backwards; pending (0) isn't
extrapolated.
Performance:
- Explorer block list uses loadRangeCached() (memoized on the cache revision) instead of loadRange(), so it
only hits SQLite after the cache changes, not every frame.
Tests: testResilienceMediums (tip gate, confirmations-advance, dropped/stale predicates) + loadRangeCached
memoization in testExplorerBlockCache (isolated on its own cache). Held: Overview/Balance per-frame list
cache, peers clippers, off-thread tx-history cache load (larger refactors).
