/**
 * runbook/coverage — the spine's ledger: inner folds + chart-declared
 * entries + the bridge's own, and the sentence naming the rules.
 *
 * Pattern: pure fold over three sources, reusing the coverage primitives'
 *          own recognizer and merge — no second grammar.
 * Role:    core/runbook.
 * Emits:   N/A.
 *
 * The three sources, in the order they land:
 *   1. INNER LEDGERS — every recorded inner call's result is read by the
 *      same `readCoverageResult` funnel the dispatch loop uses, and its
 *      three lists fold upward. An inner tool's honesty is carried, never
 *      re-authored.
 *   2. THE CHART'S OWN — the procedure states run-specific coverage by
 *      writing a `coverage` state key (`{ checked?, not_checked?,
 *      cannot_cover? }`, items as `{what, why?}` bags or bare strings).
 *      This is the app's vocabulary (which counters mean "not assessed" is
 *      the chart's to know); the ENVELOPE is the bridge's.
 *   3. THE BRIDGE'S OWN — one `checked` entry naming the procedure, its
 *      recorded step count and the rule set it ran under; and, for a
 *      verdict-shaped runbook, a `not_checked` entry counting DECLINED rows
 *      (the three-outcome honesty: a row that reached no classification is
 *      ground the answer does not cover).
