// ─────────────────────────────────────────────────────────────────────────────
// #3807 — advance-plan must refuse a Current Position section carrying
// more than one `Phase:` entry instead of silently advancing the first.
//
// The #2956 fix scoped the milestone-conflict Phase read to the Current
// Position section, but advancePlanCore's plan fields still came from
// document-wide first-match stateExtractField — so a wave-log style section
// (one Phase: entry per completed wave, all under Current Position) had its
// FIRST entry's plan counter silently advanced — in the reporter's incident,
// a hard-gated final plan 7→8 of 8 — with advanced:true and
// milestone_conflict:null, no error, no ambiguity signal.
// ─────────────────────────────────────────────────────────────────────────────
