Total Dash supply is far below u64::MAX so overflow is unreachable in practice — this is defensive correctness, not a bug fix. Four sites are kept saturating with explanatory comments because the saturate-to-zero path is part of the algorithm rather than an unreachable overflow guard: - fee_target_max may legitimately go below zero for a thin fee target; the headroom check then rejects that prefix size. - total_output - other_total may go below zero when peers alone cover the outputs; the max(min_input_amount, ..) wrapper recovers the intended floor. - The Phase 5 debug_assert exists to catch a negative remaining (saturating to 0 trips the >= estimated_fee check). - Phase 2's last-entry trim has a proven-by-construction lower bound (surplus < last_balance) — saturating is documentary defense.

The Ok-branch redistribute invariants the docstring promised were never asserted. Engineer the fixture against the real fee schedule (input_cost=500_000, output_cost=6_000_000): addr_x=10M (fee target), addr_y=80k (sub-min peer), addr_z=2M (large peer), total_output=4M. Phase 1 grows to [x,y,z]; Phase 3 finds headroom; Phase 4 folds y's 80k residue into x; final selected = {x: 2M, z: 2M}. Replaced the lenient panic-on-unexpected-variant guard with hard assertions on the Ok branch — every selected input ≥ min_input_amount, sub-min y must NOT appear in the inputs map, the fee target absorbs the folded residue, Σ inputs == Σ outputs, and validate_structure greenlights the result. Addresses thepastaclaw's deferred review feedback on PR #3554.

Replace that with a typed PlatformWalletError::OnlyOutputAddressesFunded { outputs } variant, detected after build_auto_select_candidates returns empty by re- scanning address_balances with the outputs filter dropped. The Display template interpolates {outputs:?} so error.to_string() carries the offending addresses across boundaries that flatten typed error variants (notably FFI). Pure-helper unit tests pin three branches: typed-payload happy path, none when no funded address, none when a funded non-output exists. An end-to-end integration test driving auto_select_inputs through the typed-error branch (QA-002) would require a WalletManager harness this crate doesn't yet expose; the production code path is annotated with a TODO(QA-002) referencing the pure-helper coverage. Removed the QA-001-followup TODO superseded by the typed error variant. Addresses Marvin's QA-001 (Display interpolation) and QA-002 (the detection logic), and PR #3554's deferred TODO.

Out-of-order completion of a stale scan (network jitter, retry, parallel pass) could roll the watermarks backwards and trigger redundant rescanning, undoing earlier progress. Replace the unconditional assignment with a per-field max so each counter is monotonic in isolation. Per-field rather than all-or-nothing: a result that advances some fields and regresses others should still lift the advancing ones — tying the watermarks together would either lose progress (reject the whole result) or roll some fields back (accept the whole result). `set_stored_sync_state` keeps the unconditional overwrite — it's the load-from-persistence entry point, used before any incremental result has merged. Documented the asymmetry in both rustdocs. Four unit tests in `provider::tests` pin the four observable shapes: forward advance, full backwards rejection, per-field merge, and the loader's unconditional overwrite. The provider is constructed with a minimal in-memory `WalletManager::new(Network::Testnet)` plus empty maps — no I/O, no SDK round-trips.

Downstream consumers (Swift, FFI tests, telemetry) couldn't distinguish these failures from a generic unknown error, defeating the typed-error work in the upstream rs-platform-wallet hardening pass. Allocate two new FFI codes (ErrorArithmeticOverflow=13, ErrorOnlyOutputAddressesFunded=14) and route the matching wallet variants to them via an explicit `match` in the From impl. The Display rendering — including QA-001's outputs payload interpolation — still flows through as the message, so callers without typed-error access can recover the offending addresses by parsing the message. Three new tests in error::tests: each new variant maps to its dedicated code with the typed Display preserved as the message; the catch-all ErrorUnknown remains the only fallback for unmapped variants. Surfaced by Marvin's QA audit of the rs-platform-wallet hardening branch.
