The API, MCP, batches and the CSV import copied any value and Normalize
replaced it with the default, answering 201 for a 307 saved as a 301.
RedirectFields.Problems refuses values outside {301, 302, 410}, {exact,
pattern, regex} and {ignore, pass} with value_invalid; the import marks
such rows refused.
- POST /_seo/api/v1/batch runs changes in one transaction: dry_run
answers the diff and the conflicts (loops, chains, noindex on a
published record, canonicals to redirected or noindex addresses) and
rolls back; a refused change refuses the batch (D-12)
- undo of a change or a whole batch from History and through MCP, with
the undo_stale, undo_loop and undo_gone refusals (D-13)
- CSV export and import of redirects, rules and records by URL: BOM,
comma or semicolon, formula cells escaped, a dry-run preview, all or
nothing with via import; the screen's apply token is HMAC-SHA256 over
the file and a fingerprint of the data (transfer.stale)
- Import and export singleton with the seo_transfer widget action,
History record actions undo and undo_batch, navigation entry
- MCP tools undo_change, undo_batch, apply_batch, export_csv, import_csv
- TestBatch, TestUndo, TestCSVTransfer, TestLoopRefused mcp and import
- /_seo/api/v1 routes for the effective SEO of a URL with sources and
owner, URL rules, redirects (loops refused with redirect_loop), the
404 log actions, robots.txt and its tester, settings and history
- the CMS-data issue report: missing and duplicate titles and
descriptions, rules over records, redirect chains, canonicals to
noindex or redirected addresses, noindex addresses robots.txt blocks
- 24 MCP tools on those routes (backend guard, golem15.seo.manage)
- AdminOperations maps every admin operation to its tool;
TestEveryAdminOperationHasTool and TestMCPReadToolsAreGET guard drift
- robots.txt writes go through classes.SaveRobots from the admin too
