Validate every rule change on deterministic replay fixtures through the supervisor, the rule, and the paper adapter on a fixture clock before it may touch a ticket.
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
# Replay and Backtest ## L1 - Summary No rule change reaches a ticket without first surviving replay. Run `pumpgrok run --mode paper --once --replay tests/fixtures/replay/<dataset>` to execute the candidate rule against recorded history through the supervisor, the rule, and the paper adapter on a fixture clock. Replay ledgers live under `var/replay/<dataset>/` with `source=replay` and never feed live metrics. ``` rule change -> replay on fixtures -> metrics match bar -> paper trial -> ticket flow rule change -> replay fails -> rule stays out ``` ## L2 - Method 1. S1 - Pick the dataset: use the fixture set matching the market regime under test (default `tests/fixtures/replay/smoke` for the smoke path). Recorded fixtures only; never replay against live endpoints. 2. S2 - Run the replay gate: `pumpgrok run --mode paper --once --replay <dataset>` drives the supervisor, the rule, and the paper adapter with a fixture clock, so ids and fills reproduce byte-for-byte. (The lighter `run_replay` checkpoint only writes its verdict row first and does not run the paper adapter.) …

How to install
mdr add swcstudiospace/pumpgrok/replay-and-backtest@sha256:1406d6e737cc9676The line at the top of this page pins the label git:20261026.1405e61, 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.
