Use when a backtest result needs a durable record of exactly what produced it: git commit SHA, per-file data checksums, hyperparameter manifest and environment, signed with HMAC for integrity against outsiders.
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
## When to Use Invoke this skill when performing strategy validation prior to live deployment or institutional client presentation, and you need a durable record of exactly what code, data, and parameters produced a set of backtested numbers. It captures git commit SHA, per-file input data checksums, hyperparameters, performance metrics, and execution environment, then authenticates the record with HMAC-SHA256 so later modification by anyone without the signing key is detectable. ## When NOT to Use - **As proof to a regulator that your firm did not alter its own results.** HMAC is symmetric: whoever can sign can also forge. This gives integrity against outsiders, not non-repudiation against the issuer. See the trust-boundary note below. - **As a substitute for compliant recordkeeping storage.** Under 17 CFR 240.17a-4(f) the durability obligation is met by the storage system (WORM or the audit-trail alternative), not by a hash embedded in a file. - **For live order/trade event capture.** Order and execution event reporting is a different obligation with different systems — see the CAT and RTS 25 notes in `references/standards.md`. …

How to install
mdr add himanshuj16/algo-trading-skills/backtest-audit-trail-for-regulatory-review@sha256:26ce3ea064ad5dc9The line at the top of this page pins the label v2.0.0, 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.
