- seo_schema (seoschema, E8) with the C17 server rules: invalid JSON with
line and column, non-objects, 16 KB, depth 8, a literal <script and a
type outside the kind's list refused; the value re-serialised
- a custom node with a generated @id merges into it (schema.merged save
notice), other nodes are appended to the graph
- seo_primary_parent (seoparent) for article types; both values stored
in the entry data on every locale row
- the seo_graph widget action (E9 data), P1 primary_gone and the P2
schema type and breadcrumb trail rows
- GET /_seo/api/v1/graph and MCP seo_get_graph; seo_set_url_seo and
apply_batch accept primary_parent and schema
The graph tool lands with the validation: the operations parity test
binds the seo_graph widget action to its tool.
- every write that records history (admin, MCP, batch, import, undo,
automatic) queues the framework's site-cache purge (kind seo, slug the
address or * for settings and robots.txt) after its commit, once per
transaction; a rolled-back write never purges
- the record-deleted cleanup and the address tracking of saves outside the
admin run in lagoon transactions, so their history purges as well
- 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
