planConsolidate returned already-healthy only for wallets with EXACTLY
2 UTxOs, but buildConsolidateWalletTx lands 3 (collateral + working +
the fee-reserve remainder as change). The shape consolidation produces
can never satisfy its own health check, so every wallet-health tick
re-consolidates and pays the ~0.5 AP3X min fee again. Measured in a
production deployment: a 45s ticker submitted 232 consolidations and
burned ~116 AP3X in about 2.5 idle hours; at the default 600s interval
the same loop leaks ~3 AP3X per hour whenever the wallet is not exactly
2 UTxOs.
Healthy is now structural: a pure-lovelace UTxO >= collateralLovelace
exists, at least 1 AP3X sits outside it, and fragmentation is bounded
(<= 6 UTxOs, new optional maxUtxos param). The health check also runs
BEFORE the low-balance guard, so a wallet that can already run script
transactions is never reshaped or refused. walletHealth gains two
independent circuit breakers - halt after 3 consecutive consolidations
that never reach healthy, halt past 6 consolidations per 24h - so any
future non-convergence costs at most ~1.5 AP3X instead of the whole
wallet, plus a docstring that matches reality.
Tests: the exact post-consolidation-shape regression, one-step
idempotence against the builder output model, candidate boundaries
(native assets, 1,628-lovelace-short), healthy-below-reshape-threshold,
and breaker behavior including error and reset paths.

Adds a one-shot operational tx that re-shapes any operator wallet to
{5 AP3X collateral candidate, working remainder} so subsequent Plutus
script-spends (Claim/Submit/Accept/Reclaim/RetireAdvert) find a UTxO
that satisfies lucid's setCollateral=5_000_000n default coin selector.
Symptom this addresses: open-webui mainnet supplier wallet held 8 UTxOs
max 2.40 AP3X, every Accept tx failed at lucid .complete() with the
"wallet must hold a pure-ADA UTxO ≥ 5 ADA" error path. Same fragmentation
risk on the other 4 mainnet operator wallets (one big UTxO surrounded by
dust — first script-spend consumes the big one and leaves nothing usable
as collateral).
Phase 1 — new tx:consolidate-wallet CLI (supplier + buyer):
- planConsolidate.ts — pure planner; supports consolidate (N>1 → 2),
split (1 → 2), and already-healthy skip.
- consolidateWallet.ts — live builder; presetWalletInputs pins all
UTxOs, two pay.ToAddress outputs (collateral + working).
- runConsolidateWallet.ts — orchestration (build + submit + awaitTx).
- supplier/src/cli/consolidate-wallet.ts + buyer mirror.
- monitor-wallets.ts — add supplier-tts@vector-marketplace (was
misclassified as 3rd-party).
Phase 2 — defensive pre-check in the 5 script-spend builders:
- assertCollateralCandidate(utxos) fires at the top of
buildSpendOpenOrClaimedTx (Claim/Submit), buildLiveTxForAccept,
buildLiveTxForReclaim, buildLiveTxForRetireAdvert. Throws a
TxConstructionError("collateral_required") pointing at
tx:consolidate-wallet instead of waiting for lucid's deep failure.
Tests: 12 new passing (planConsolidate edge cases + assert helper).
Pre-existing lucid 0.4.30 WASM "unreachable" failures in tx-*-live.test.ts
fixtures are unchanged.
