Each playbook describes inputs, safe steps, failure modes, handoff and the condition for stopping.
Content state: draft Owner: owner:methodology Next review: 2026-09-07
ClaimAn atomic, verifiable statement linked to evidence, a coverage envelope and separate human assessment dimensions. → evidenceResearch material whose provenance, time, integrity state and link to an exact source version are preserved.
Decompose the claim, test source independence, preserve exact anchors and use honest abstentionA decision not to make a stronger conclusion when evidence is insufficient or conflicting, with the gap stated explicitly..
- Input: the original claim and context.
- Output: a claim matrix and a short editorial brief.
- Stop: rights, coverage or independent grounds are missing.
Public procurement
Compare open identifiers and documents without turning a match into a misconduct conclusion.
- Input: a public notice and time-versioned sourceA source state fixed at a point in time with a digest, locator and change description..
- Output: a traceable relationship or not confirmed.
- Stop: no primary document or disclosure risk.
Media + Geo + time
Build a timeline and geographic context without presenting estimated precision as fact.
- Input: publication, map and timestamp.
- Output: a consistent or conflicting timeline.
- Stop: dates, coordinates or rights are not comparable.
Public-data diffA deterministic comparison of two versions that shows an observed difference, not its cause.
Understand a change between open-series snapshots without assigning an unsupported cause.
- Input: two reviewed snapshots.
- Output: an observed change with alternatives.
- Stop: the method or period changed.
Correction and abstention
Preserve what was said, what changed and why the conclusion is bounded.
- A correction is a new version, not a silent edit.
- Abstention is a result with an explained data gap.
- Handoff goes to a named editor or risk owner.
