# Build the evidence ledger Use when `evidence` is the current gate. - Read repo instructions, `PRESENTATION-BRIEF.md`, `SOURCE-INVENTORY.md`, and the cited source files before writing new claims. - Read the current mode from `STATUS.md`; do not assume the mode selected at intake is still current. - General mode keeps evidence proportionate. - Record provenance and sufficient qualification for material claims. - Write `EVIDENCE-LEDGER.md` from `templates/EVIDENCE-LEDGER.md`. - Create one row per material claim, not one row per source file. - Record the exact source, source type, caveat, allowed use, and the slide or range the claim may support. - Add dates, definitions, units, or methods when they are necessary to keep a material claim honest. - Use `references/claim-safety.md` for research-enhanced claim safety. Research-enhanced mode alone adds A/B/C/D claim safety. - `A`: directly supportable in the main talk. - `B`: reasonable interpretation with careful wording. - `C`: contested or context-dependent, notes or backup only. - `D`: unsafe or unsupported, reject. - Record exact dates, definitions, units, denominators, and methods. - Record correlation-versus-causation review. - Record competing measures and stale-value checks. - Apply official and primary-source preference before secondary summaries. - Add backup/reference safeguards for contested, overflow, or Q&A-only material. - Move unsupported but useful material to notes or backup only when the wording stays hones
