/**
 * The disposition ledger — nobody's silence goes uncounted.
 *
 * Pattern: small mutable accumulator behind a read-only report, the
 *          context-ledger ingestion shape (accumulate during, read after).
 * Role:    every Context Integrity check files one disposition per
 *          encounter here. The ledger's two jobs:
 *
 *   1. THE INVARIANT — for every check that was registered, an encounter
 *      count of zero is itself reportable. `assertAlive()` fails when a
 *      registered check saw work available and filed nothing at all —
 *      which is the wiring-rot failure mode ("the checker was unhooked and
 *      the suite stayed green"), distinct from a clean run (encounters
 *      with zero findings — healthy) and from a quiet run (no applicable
 *      work — also healthy, and stated as such).
 *
 *   2. THE CANARY — in dev posture, a run mints one deliberately
 *      contradictory synthetic encounter per registered check at start.
 *      A checker that cannot catch its own canary is dead, and the run
 *      says so by name instead of shipping a green report. Synthetic
 *      findings are counted apart and never touch the real numbers.
 *
 * Everything here is plain data; `report()` returns fresh POJOs safe for
 * events, snapshots, and recordings.
