Indus Script Falsifiability Ledger (V2–V3 Integrated): A Collaboration-Ready Two-Rater Framework

This record introduces a neutral, collaboration-ready falsifiability ledger designed to make Indus script claims comparable, reproducible, and peer-checkable without requiring agreement on a single decipherment. Version 2 established the claim-by-claim ledger approach: isolate a claim, log the specific evidence used, and record outcomes in a structured, auditable format. Version 3 expands the system into a collaboration surface by separating transcription from word-level claims, adding anchoring categories (P/A/O), introducing traffic-light confidence for key decisions, and requiring a two-rater peer check with explicit disagreement handling. Scope note: This is a methodological logging and peer-check framework for testing claims; it does not assert translations or a completed decipherment. How to use (quick start): Select ORI/OVR, log the claim and the evidence basis, assign traffic-light confidence to key decisions, then complete a two-rater peer check (R1/R2) to record agreement or disagreement as visible data. Companion worked examples (including CL2 “Buffalo”) will be released separately as a follow-up record (v3.2) to demonstrate the scoring workflow using this framework. Parallel samples in Egyptian hieroglyphs and the Meroitic (Kushite) script are being developed to test how well the ledger transfers across writing systems.
