6593 - * imports only; this fixes rows already in the table without the customer
6594 - * having to re-source and re-upload the original PDFs (plan d1e6f7).
6595 - *
6596 - * Detection reuses MxChat_Utils::normalize_pdf_rtl() on the stored text: a
6597 - * row is a candidate exactly when the normalizer would change it, so the
6598 - * import-time heuristic and the repair heuristic can never disagree.
6599 - * Repaired rows are RE-EMBEDDED — the stored vector was computed over
6600 - * reversed text and is as broken as the text — so a wet run calls the
6601 - * embedding provider once per repaired row on the site's API key. Runs
6602 - * beyond 25 rows therefore require --yes.
6603 - *
6604 - * Scope notes:
6605 - * - Scans the WordPress knowledge table. Pinecone-mode entries live in
6606 - * Pinecone, not this table, and are not scanned; if a scanned row's bot
6607 - * ALSO has Pinecone enabled (hybrid drift), the repaired entry is
6608 - * re-submitted through the normal import path so the md5-keyed Pinecone
6609 - * vector is replaced too.
6610 - * - Knowledge rows do not carry a bot id; --bot only selects whose
6611 - * embedding configuration (model + key) is used for re-embedding.
6612 - * - The mxchat_pdf_rtl_normalize filter is honoured: a site that disabled
6613 - * normalization gets detections of zero, not surprise rewrites.
6614 - * - The metadata header the PDF importer stores before the text separator
6615 - * is preserved byte-identical; only the text segment is repaired.
6616 - *
6617 - * ## OPTIONS
6618 - *
