Tools (3)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • amu_check_conflict

    Check whether another department has already recorded a conflicting definition of the same metric_name (same name, different derivation / definition_hash). Returns only department names and hashes -- never values or lineage -- so this cannot become a side channel around the gate.

  • amu_record

    Record a new Analytical Memory Unit (AMU). Lineage is extracted from the executed `sql` (ground truth), never self-reported. Requires an amu_writer-member Postgres role -- other roles get a Postgres permission error, not a silent no-op.

  • amu_search

    Search lineage-gated Analytical Memory Units (AMUs) by semantic similarity to a natural-language query. Results are lineage-gated by Postgres row-level security under this server's own Postgres role: an Analytical Memory Unit (AMU) is only ever returned if every sensitive column touched by its derivation is in this role's permitted set. This tool cannot bypass that gate.
