/**
 * CartographerSweepEngine — the reusable, efficient, safe author loop for the
 * doc-freshness sweep (spec #2). One `runPass()` is ONE tick's worth of work on
 * the lease holder. The poller (CartographerSweepPoller) drives cadence,
 * reentrancy, the breaker, and re-escalation around it.
 *
 * Every brake the spec requires lives here so spec #3 (the registry-wide
 * conformance audit) can reuse the SAME engine and inherit the efficiency +
 * safety invariants automatically:
 *   - lease-gating (author only on the lease holder — no multi-machine N× burn);
 *   - a routing PROBE that refuses to author on the default (Claude) framework;
 *   - deepest-first ordering (children before parents) + dir-defer + anti-starvation;
 *   - dual per-pass bound (node count AND estimated spend);
 *   - the dir re-author amplification guard (childDigestHash → fingerprint-only refresh);
 *   - input cap + committed-state-only reads + secret exclusion (path glob + tripwire);
 *   - a DETERMINISTIC quality bar (symbol presence — no self-grading LLM);
 *   - mid-tick CPU re-sampling (curtail at moderate, break at critical);
 *   - LlmAbortedError treated as backpressure, not failure;
 *   - per-node quarantine after K consecutive author failures;
 *   - an idempotent within-tick cursor that can never exceed the per-tick caps.
 *
 * Pure of cadence/timers — those are the poller's job. Deps are injected so the
 * whole loop is unit-testable against a fixture tree with stub router/queue.
