synq-recon compares a dataset in one database against a dataset in another and tells you whether they agree — without moving row data. It uses hierarchical checksum bisection, so by default only counts and checksums leave the database, and locating the specific rows that differ costs O(log n) queries rather than a full scan.
First public release. Previously the binaries were only reachable inside our own organisation.
AGENTS.md in this archive is the operating guide — the loop to follow, every command and flag, how to read the output, exit codes, and what each command costs. It is written for a coding agent to read top-down and act on. Same content at docs.synq.io/reconciliation/agent-workflow.
Start at Getting started — the walkthrough runs against DuckDB, so it needs no warehouse and no credentials.
