Turn a plausible hypothesis into an earned verdict with the cheapest experiment that can kill it — binary oracle with a canary value, a negative control inside the same run, prediction stated before execution, novelty gate before writing, and every link in the evidence chain labelled by epistemic level. Use whenever a security finding, bug hypothesis, or root-cause claim needs to be confirmed before reporting, when building a PoC, when the user says "prove it", "confirm the bug", "reproduce…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Discriminating Proof A hypothesis confirmed by reading is a hypothesis confirmed by the layer of the system you happened to read. The verdict that survives a hostile reviewer is earned by a run — one designed so that its failure would falsify the claim and its success cannot be explained by anything else. The discipline in one line: **the run outranks memory, the control outranks the result, and the ladder outranks enthusiasm.** Composes with the library: - **falsifiable-testing** — the test-design discipline behind the oracle - **red-team-auditing** — the epistemic ladder this skill enforces - **daubert-defensible-writing** — how the earned verdict gets written up - **deterministic-core** — the PoC must be reproducible by the reviewer - **claim-provenance-discipline** — each link keeps its level into the report --- ## Part 1 — The epistemic ladder: cap every claim at its rung Every assertion carries exactly one level, and the level is set by the strongest evidence actually obtained — never by the strength of the chain's other links. - **CODE FACT** — verified in the live source, with file and line. "Pipeline order is X", "the cleanup set is exactly these two names". …

How to install
mdr add annatchijova/skills/discriminating-proof@sha256:b903a62681542364The line at the top of this page pins the label git:20260821.38a2b1d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
