Query the ledger replica for transfers, balances, and audit rows. Use when debugging data issues in acme-api.
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
# Ledger Query
Use the query tool to pull rows from the ledger replica. For example:
query(sql="SELECT * FROM transfers WHERE id = 42")
Another example, limiting columns:
query(sql="SELECT amount FROM transfers WHERE id = 42")
A third example, joining audit rows:
query(sql="SELECT * FROM audit WHERE transfer_id = 42")
Never run queries against the primary; the replica lags at most 30
seconds and that is always acceptable for debugging.Read the whole file at its exact version.
How to install
mdr add stbenjam/skillsaw/ledger-query@sha256:a30413fc79d92f8fThe line at the top of this page pins the label git:20260807.7d619c5, 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.
