Apply when writing or gating any report that makes a causal claim or summarises a cumulative outcome — a backtest, an experiment write-up, a capacity or cost model, a postmortem, an eval summary, a benchmark table. The report must carry what would change the reader's decision: what observation would refute the claim, whether the path crossed a state it could not return from, what the headline was before and after the fix, and which unvaried assumption flips the sign.
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
# Report the disqualifier A report is not finished when its numbers are correct. It is finished when a reader who disagrees with it knows exactly where to look. Every claim has a disqualifier — one observation that would sink it — and a report that omits its own disqualifier is persuasive in proportion to how wrong it can be. Four disqualifiers, four sections. Use the ones that apply. ## 1. What would refute this Any causal claim states, in the same document, the observation that would falsify it — a measurement, not a hedge. "This may not generalise" is not a falsification section; "if the effect survives when X is held constant, the mechanism is not X, and here is that run" is. Grade every claim in the report on one visible scale — **measured / inferred / conjecture** — and put the grade next to the claim, not in a preamble. A reader must be able to strip the report to its measured rows and see what is left. ## 2. Did the path survive A summary statistic computed over a path can describe a path that ended. A positive year through an account that was liquidated in March; a mean latency across an interval containing an outage; a mean reward over a trajectory that …

How to install
mdr add edbertchan/catstack/principle-report-the-disqualifier@sha256:dad9a3a3aa15e759The line at the top of this page pins the label git:20260909.c3c9414, 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.
