{"content":"higun dev journal — docs: add higun mvc shifted-spend incident runbook (3efff10)\n\nWrote the incident runbook for the MVC mainnet shifted-spend corruption: root cause chain (mempool row contamination + positional owner lookup), the inversion finding (/balance was the wrong side, /utxos was right — 1LFYPB really holds 1 UTXO / 175,808 sat, not 19 / 11,068,196,528), the repair procedure (stop container, repair_shifted_spends apply+clear-balance, fix_single_spend to re-append the 88c9e085:950 spend that was silently dropped in 2026-06, restart, verify), acceptance checks, and the business impact note: the 11B sat 'inventory' was phantom — the funds were already consumed by the pool's own split/gas churn chain, so the assist reward pool needs real refunding, not just an index fix.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
