    "kind=unknown = the classifier could not decide (no explicit list, no matching script pattern). Treated as a third bucket, not a failure.",
    "NEITHER band (30-72h by default) is only 42h wide, so hitting it is structurally rare for daily cron. STEP 1599 v0.1 reported 'bimodal distribution' as a finding — that was inaccurate; it is a threshold-design artefact. Fixed in v0.2 honest scope.",
    "For source-specific tuning (weekend-only feeds, sub-hour cadence, weekly refresh), thresholds should be normalized as multiples of the source's own cron interval. That is a v0.3+ change; v0.2 keeps global thresholds.",
    "FLOWING on kind=cron IS a real fetcher bug (missing generatedAt header). FLOWING on kind=artifact is normal (STEP outputs need no timestamp).",
    "harvest_lag (comparator vs external API) is a separate gauge — see STEP 1601.",
    "v0.3 (STEP 1606): each record now carries kindSource ('allowlist'/'denylist'/'heuristic-script'/'unknown-fallback') so heuristic wobble is visible per-record and in the kindSourceBreakdown summary (chat-Claude STEP 1605 review 2026-08-31).",
    "v0.4 (STEP 1608, chat-Claude 2026-08-31 pt ①): artifactSummary and unknownSummary carry {total, verdict:'N/A', reason} instead of numeric fresh/aging/stale/dead/flowing counters. Downstream JSON readers cannot accidentally aggregate excluded populations into cron health. Per-record verdict is still computed and preserved (for later inspection); excludedFromAggregate:true marks non-cron records.",
    "v0.4 (STEP 1608): boundary crossings ARE observable in real cron data — chat-Claude second review documented a cron TRUE→NEITHER transition inside a 16-minute window at the 30h threshold. Bimodal ★ retraction stands; per-source cron-interval normalization (candidate E) is the correct next move."
