On-air read

A one-word call on whether the circulating version is safe to say on air, judged against the origin:
Accurate — faithful, cleared for air.
Bent — context was lost; add it before using.
Fabricated — not supported by the origin; don't present as fact. It reads the reliability of the final stage.

fabricated

FABRICATED / DISTORTED — do not present as fact

The circulating version is not supported by the origin.

Reliability grade

Each stage is graded High, Medium, or Low for how faithfully it carries the origin's meaning. The first stage where the grade drops below the one before it is flagged as where distortion entered.

  1. 0Peer-reviewed studyOrigin
    High reliability

    “In mice, compound X reduced a marker under lab conditions.”

  2. 1University press release
    High reliability

    “Promising early results for compound X, more research needed.”

    What changed: kept the caveats

  3. Distortion enters here
    2News headline
    Medium reliability

    “Compound X 'fights disease,' scientists say.”

    What changed: dropped 'in mice' + 'early'

  4. 3Viral social post
    Low reliability

    “Doctors confirm X CURES disease — they don't want you to know!”

    What changed: added false certainty + conspiracy

Tamper-evident

Every stage is fingerprinted (SHA-256) and folds in the previous stage's fingerprint. Change any earlier stage and every later fingerprint changes too — so the chain of custody is tamper-evident. The black window is a read-only audit view.

Each link folds in the previous link's hash, so editing any earlier stage changes every hash after it.
