The unchecked background resolved to colorScheme.surfaceContainerHighest,
which is pure white in LightTheme, so the unselected checkbox was an
invisible white disc on near-white list rows. In light brightness use
onSurfaceVariant with alpha 80 instead; dark themes are unchanged.

* Randomize coin selection with single random draw
The greedy selection walked the unspent pool in a predictable order (address generation order, then per-address server order), a fingerprint an analyst can exploit. Shuffle the pool before the accumulate-until-covered loop so the input set is chosen non-deterministically (single random draw). MWEB coins are still kept last.
Branch-and-bound (changeless exact match) is a larger follow-up.
* Add BnB + SRD coin selection primitives
Pure, wallet-independent coin selector: branch-and-bound for an exact
changeless match within the cost-of-change window, single-random-draw
fallback (shuffled, injectable RNG) when no exact match exists, and
selectCoins tying them together over effective values.
This is the basis for replacing the greedy accumulation in _createUTXOS
so sends produce no change when possible and a non-deterministic
selection otherwise. Validated with dart test (9 cases); wiring into
_createUTXOS is a separate step.
* Use BnB changeless matching in coin selection
Before the shuffled greedy walk, run branch-and-bound over effective
values (value minus per-input fee cost) looking for an input set whose
excess over amount plus fee stays below dust. When found, order those
inputs first and cap the walk at their count: the caller then computes
a change below dust, drops the change output, and absorbs the residue
into the fee, producing a changeless transaction with no residual
change fingerprint.
When no match exists, selection falls back to the shuffled pool, which
the greedy walk turns into a single random draw. BnB is skipped for
sendAll, forced input counts and pools holding MWEB coins.
changelessMatch filters non-positive effective values and maps indices
back to the original pool.
* Cover changeless fee bounds and BnB termination
Assert the end-to-end arithmetic the wallet performs around a
branch-and-bound match: with the 68/34/10 vBytes model, the leftover
the caller absorbs into the fee is never negative (no re-selection
loop) and never exceeds the dust limit (bounded fee overpay).
Also pin termination: a large pool with no possible match returns null
through the maxTries cap instead of exploring the full search tree.
* Use a secure RNG for coin selection randomness
The selection shuffle and the single-random-draw fallback exist to be
unpredictable, so seed them from Random.secure() instead of the default
PRNG, matching what Core and bdk use for coin selection. Pool sizes are
small, so the cost is negligible. Tests keep injecting a seeded Random
for determinism.
* Randomize RBF and payjoin input candidate order
Two secondary paths still consumed unspentCoins in wallet scan order
(address generation order, then per-address age), the same predictable
order removed from the main selection path:
- replaceByFee walked the unused-UTXO list in scan order when the fee
bump needed extra inputs
- the payjoin receiver handed input candidates to the payjoin library
in scan order, letting ties inside its selection mirror that order
Shuffle both with a secure RNG so no input-selection path exposes the
wallet's address or coin age ordering.
* ci: skip Linux PR build on forks (no secrets access)
* Account for script-type sizes in changeless matching
* Keep coin selection order stable within a transaction build
* Set anti-fee-sniping locktime on bitcoin sends
Current tip (exact-tip) via shared helper, wired into normal sends (path A) and payjoin/PSBT (path B). 0 when unsynced. Converges with the exact-tip cluster (payjoin-cli, ldk-node, Bull Bitcoin) and skips the ~10% backdate.
