/**
 * Manifest stability — stop real findings silently vanishing between reruns.
 *
 * Intent extraction is LLM-driven and non-deterministic: three same-day
 * islandlink runs (2026-07-20/21) extracted 18 → 17 → 16 flows, and the one
 * real bug (run A's SetupIntent-retrieval 500) was absent from run C's claim
 * set with no trace. Two mechanisms fix this:
 *
 * 1. Manifest reuse: on an unchanged repo (content fingerprint match) the
 *    prior confirmed manifest is reused, making the claim set deterministic
 *    across reruns. `--refresh-manifest` forces re-extraction.
 * 2. Claims diff: every run compares its claim set against the previous
 *    run's and reports "dropped since last run" — so when the manifest DOES
 *    legitimately change, a vanished claim is visible instead of silent.
 *
 * Capsule: assay-claim-set-stability.
