Use when judging whether your change is clean against a red or noisy baseline — failing tests you didn't touch, pre-existing lint/typecheck errors, flaky CI. Innocence is a claim about a delta, so prove it by stash-and-compare or head-vs-base under an identical harness, never by reading which files appear in the failure list. Triggers on "is this failure mine", "pre-existing failures", "red baseline", "did my change break this", "CI was already failing", "flaky", and before blaming or clearing…
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
# Measure the Delta, Not the Absolute **Type:** Open-source — client-agnostic methodology, no project-specific detail. **Created by akbarsha — https://github.com/iamakbarsha1** Distilled from cases where a red or ambiguous test/lint/typecheck result was nearly (mis)attributed to the current change when it was pre-existing or environmental. **Licence:** Released under CC BY 4.0 — share and adapt for any purpose with credit. Full text: `LICENSE` at the repository root. **Feedback & Support:** If a rule here proves wrong or needs sharpening, open an issue on the repository or contact the author at the profile link above. If the problem is the agent not following a rule below rather than the rule itself, that's an execution failure — acknowledge and correct it. ## The core rule On a red or noisy baseline, "my change is clean" and "this failure is mine" are both claims about a DELTA, not an absolute. Prove them differentially: run the same check against the code WITHOUT your change under an identical harness, and compare. Never infer innocence (or guilt) from which files happen to appear in a failure list — a failure can reference a file you …

How to install
mdr add iamakbarsha1/whetstone/measure-the-delta-not-the-absolute@sha256:c4b65f27f1e473b8The line at the top of this page pins the label git:20261019.9af84f1, 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.
