Balance/history now render as soon as tx downloads finish instead of
blocking on every historical Merkle proof, critical for mobile where
proof-checking can take much longer than the download itself. Proofs
continue to be checked in the background and each tx's Verified flag
catches up progressively; header ranges are now fetched in batches
(blockchain.block.headers) instead of one call per header to keep this
fast over high-latency links.
Coin selection (UtxoSpendability.IsSpendable) refuses to spend a UTXO
until its Merkle proof is actually checked, regardless of confirmation
count, so a server that fabricates a confirmed balance can get it
displayed early but never spent before the forgery is caught. The disk
cache only ever persists the fully-verified end state of a sync.
UI surfaces the new PendingVerificationSats/SpendableSats split with a
"verifying..." badge, and the sync save now runs off the UI thread to
avoid freezing on slower hardware.
Transaction detail view silently dropped OP_RETURN messages and coinbase
scriptSig text (e.g. pool tags), since TransactionInspector discarded
scriptPubKey/scriptSig bytes once no destination address could be derived.
Each output/input is decoded independently, so multiple OP_RETURN outputs
in one tx are all shown.
Input rows switch to a two-line layout (full prev-txid:index on the first
line, address + amount on the second) so nothing is cut by a fixed 160px
column. Output address column gets TextWrapping instead of TextTrimming.
Overlay grows to MaxWidth=660/MaxHeight=800 for better desktop use; the
same XAML wraps naturally on narrow mobile screens.
Removes the Shorten() helper that was masking input references.

SPV is the only verification method the wallet uses, so showing it as a
badge adds no information — if a transaction appears confirmed, it has
already passed Merkle verification.
- Remove the SPV chip from the transaction detail overlay
- Remove the Verificata column from the history list (desktop and mobile)
- Drop VerifiedText property from TransactionDetailsViewModel
- Drop the Verificata field from HistoryRow
- Remove the orphaned tx.verified loc key
Translate every Italian /// XML doc comment, <!-- --> XAML comment, and
// inline comment to English across all source files (Core, App, tests).
Add the language policy to CLAUDE.md (conversation Italian; all code
and docs English). Update one test assertion that checked an Italian
exception message that was also translated.
Transaction details overlay redesigned from a flat 12-row grid into a
scannable layout: a header with the net amount in focus plus SPV/status
badges, then three labeled cards (Overview, Amounts & fees, Technical
details), with inputs/outputs as carded rows. Adds a .section heading
style and tx.sect.* localization keys (6 languages).
Coinbase transactions are now explicitly identified: an amber "Coinbase"
badge in the header, and the misleading "From: —" / "coinbase —" replaced
with "Newly generated (mining)" (localized). Exposes IsCoinbase on the
details view model; no consensus/logic change, presentation only.

Double-clicking a history row opens an in-app overlay (same pattern as
address/server/settings overlays) that shows all available data for a
transaction. The overlay appears immediately with a spinner; data is
fetched from the server in the background and rendered once ready.
Backdrop tap and Esc close it; a pending fetch is cancelled.
New Core type — TransactionInspector (Core/Wallet/):
- FetchAsync() downloads the raw tx, all parent txs (parallel requests,
one round-trip instead of N sequential), and the block header
- Reconstructs inputs (amounts, addresses, is-mine), outputs, fee,
virtual size, RBF flag, block timestamp, confirmations
New App types:
- TransactionDetails record: full parsed data (fee, net, I/O lists,
counterparty addresses, coinbase detection…)
- TransactionDetailsViewModel: pre-formats all strings in the current
locale and unit (status, date, signed amounts, sat/vB rate…)
- TxIoRow record: one row in the input/output tables
- MineColorConverter: bool → brush (MediumSeaGreen for own addresses)
ViewModel changes:
- ShowTransactionDetailsAsync / CloseTransactionDetailsCommand
- BuildTransactionDetailsAsync (also public for future RBF/CPFP use)
- CancellationTokenSource so opening a new tx cancels the previous fetch
- All server work runs on Task.Run to keep the UI thread free
XAML: history rows get DoubleTapped handler, Hand cursor, hint label,
txid now uses TextTrimming instead of SelectableTextBlock.
i18n: 24 new tx.* / history.hint keys in all 6 languages.
