/**
 * Decay rule per finding tag. Keyed with `satisfies Record<FindingTag, ...>`
 * so this object is required to have exactly one row per tag in FINDING_TAGS
 * (phren-core.ts) — no more, no less. Add a tag there and TypeScript forces a
 * decay row here; remove one and the corresponding row becomes a compile
 * error instead of silently-dead data.
 *
 * Previously this table had 9 rows against a 6-entry offered enum that
 * disagreed with it in both directions: `anti-pattern`, `observation`, and
 * `tooling` had rows here but nothing ever wrote those tags, while
 * `tradeoff` and `architecture` were offered/writable but had no row here
 * (so they never decayed and had no max-age). The exported type stays
 * `Record<string, FindingDecayConfig>` so existing string-keyed lookups
 * (e.g. content/citation.ts) don't need to change.
