  extended_description: |
    Oracle Fusion exposes no SQL endpoint. This extension reaches its database
    the way Oracle leaves open: a SELECT is wrapped in a SOAP `runReport` call
    to BI Publisher, a report runs it through `dbms_xmlgen`, and the rows come
    back as XML.

    That detour requires a report deployed on the Fusion side — `DM_ARB.xdm`
    and `RP_ARB.xdo`, taking a `p_sql` parameter. The extension cannot work
    against a stock instance. The repository's README links the catalog
    archives, which live in the ofjdbc repository.

    Read-only by construction: BI Publisher cannot write.

    **Credentials** live in a DuckDB secret. Where the instance is behind
    corporate single sign-on, `PROVIDER browser` opens a browser, lets the
    person sign in however their organisation requires, and collects the token
    Fusion issues to that session — no client secret, no registered
    application, and no password in the process. Tokens are kept in memory
    only.

    **ATTACH** exposes Fusion's tables as an ordinary read-only catalog, typed
    from Fusion's own dictionary. Attaching costs no request; resolving a table
    costs that table's columns. Metadata is cached on disk between sessions,
    because every dictionary read is a SOAP call measured in seconds.

    **Large results** are paged by rewriting the statement, and transient
    failures are retried with exponential backoff. Requests to one host are
    serialised: each `runReport` opens a BI Publisher session that the server
    holds on to, and a handful of parallel scans leaves hundreds behind.

| fusion_scanner_filter_pushdown    | Send WHERE predicates on an attached Oracle Fusion table to Fusion. Off by default: DuckDB removes a pushed filter from the plan, so a predicate that cannot be translated exactly must fail the query rather than be approximated.                                                                        | BOOLEAN    | GLOBAL | []      | false       |
| fusion_scanner_metadata_page_size | Rows per page when listing Oracle Fusion's dictionary. Lower it if a listing keeps stopping short of the instance's own table count.                                                                                                                                                                       | UBIGINT    | GLOBAL | []      | 2000        |
| fusion_scanner_stable_paging      | Give a paged statement an order, so that its pages partition the result instead of sampling it: an attached table by its primary key (or ROWID), a query by every column it returns. On by default; turn it off only if Oracle refuses the ordering, and expect pages to repeat and skip rows when you do. | BOOLEAN    | GLOBAL | []      | true        |
| temp_directory                    | Set the directory to which temporary files are written.                                                                                                                                                                                                                                                    | VARCHAR    | GLOBAL | []      | post.db.tmp |
