test(platform-wallet): fix stale balance assertion in paloma shielded sync example

[QuantumExplorer]

Issue being fixed or feature implemented

The shielded_sync_paloma example asserted wallet A (seed [0x73; 32]) recovers a 400000-credit balance (4 × 100000) from paloma's genesis-seeded shielded notes. That expectation is stale: the genesis test-wallet note seeding was removed (see ShieldedSeedConfig::sdk_test_data in packages/rs-drive-abci/src/execution/platform_events/initialization/create_genesis_state/test/shielded.rs — wallet-balance UX no longer comes from seeded notes), so the devnet's 1M notes are filler-only and the example always panicked with balance 0 even when sync worked perfectly.

What was done?

• Replaced the balance assertion in packages/rs-platform-wallet/examples/shielded_sync_paloma.rs with what current SDK_TEST_DATA=true deployments actually guarantee:
  • the sync pass reports no per-wallet errors (ShieldedSyncPassSummary::error_count() == 0),
  • wallet A's outcome is WalletShieldedOutcome::Ok and not a cooldown skip (the example forces the pass),
  • notes_result.total_scanned > 0, proving the pass walked the seeded pool.
• Balances are now printed informationally instead of asserted (0 is the correct value).
• Updated the "What this proves" doc section to explain that no balance is expected and that decryptable-balance flows need real shielded-fund transitions post-genesis.
• Removed the now-unused COUNT_A / OWNED_VALUE / EXPECTED_BALANCE_A constants and the stale SEED_A cross-reference to the deleted shielded_test_wallets.rs.
• Still an opt-in network example: compiled but never run by cargo test.

How Has This Been Tested?

• cargo check -p platform-wallet --example shielded_sync_paloma --features shielded — compiles clean.
• cargo fmt --all — no formatting drift.
• The example itself requires a live paloma devnet, so it remains opt-in (cargo run -p platform-wallet --example shielded_sync_paloma --features shielded).

📝 Walkthrough

Walkthrough

The Paloma shielded sync example was updated to remove assertions on specific decoded balances and replace them with outcome-based criteria. The example now validates that sync completed with zero errors, produced an enabled/successful wallet state, and scanned a non-zero number of notes. Documentation and imports were adjusted accordingly, and logging was simplified.

Changes

Paloma shielded sync example assertion updates

Layer / File(s)	Summary
Example setup and documentation updates packages/rs-platform-wallet/examples/shielded_sync_paloma.rs	Top-level comment updated to describe new assertion target; imports extended to include WalletShieldedOutcome; fixed-balance expectation constants removed; green/red commentary rewritten to explain balance as informational and clarify what missing notes indicate.
Assertion and logging refactoring packages/rs-platform-wallet/examples/shielded_sync_paloma.rs	Startup config log line removes expected_balance field; sync-result verification refactored to assert error_count()==0, validate outcome is Ok, check cooldown skip is false despite force=true, and require notes_result.total_scanned > 0. Balance computation remains but prior equality check is replaced with informational logging.

🐰 A balance was fixed, now it's free,
Filler notes flow, assertions decree,
Zero errors, outcome sure,
Scanning works—the example's pure! ✨
