[[claim-yellow-rain-bee-feces-refutation-never-formally-retracted]] rests its load-bearing point — that the accusation was never withdrawn even after Meselson and Seeley's bee-feces refutation — on a single Tier-3 science-history magazine. A "the government never retracted it" claim is both surprising and load-bearing, so it should sit on a Tier 1–2 primary before the note leaves `seedling`.

## What would answer it
- The primary State Department documents: Haig's 1982 report *Chemical Warfare in Southeast Asia and Afghanistan* and any subsequent State/Defense statement — to check whether the trichothecene accusation was ever officially revised or withdrawn.
- Scholarly treatments of the controversy that track the official record specifically: Julian Perry Robinson and Matthew Meselson's own writings, and the 1980s–90s CBW-history literature (e.g. the *Foreign Policy* / *Chemical Weapons Convention Bulletin* exchanges).
- A direct statement from a government-record source that the accusation still formally stands.

## Why it matters
If confirmed, the note becomes a clean instance of the vault's recurring "a correction in the literature never propagates into the record that matters" theme. If the accusation *was* quietly revised, the whole framing collapses — which is exactly why it can't ride on a magazine paraphrase.
