+  Manual-QA demo for <datasette-sql-editor> (ticket 08).
+
+  This page is NOT served by Datasette by default. Launch a Datasette instance
+  with this directory mounted at /demos so both the demo page and the ESM bundle
+  are served same-origin (the schema fetch needs same-origin):
+
+      uv run python tests/fixtures.py fixtures.db      # once, to build fixtures
+      uv run datasette fixtures.db --static demos:demos/ -p 8001
+
+  Then open:
+
+      http://localhost:8001/demos/sql-editor-element.html
+
+  The editor imports /-/static/datasette-sql-editor.bundle.js (Datasette's built
+  ESM module, which auto-registers the <datasette-sql-editor> tag on import) and
+  fetches its schema from /fixtures/-/editor-schema.json.
+
+  QA checklist:
+    [ ] Editor mounts; "ready" logs in the event panel.
+    [ ] Typing "select st" / "facetable." offers ranked, typed column completions
+        (schema fetch succeeded). Ctrl-Space forces the completion popup.
+    [ ] Editing fires "input" events (origin: user).
+    [ ] Shift-Enter / Mod-Enter fires a cancelable "submit"; with the checkbox
+        UNchecked the form GET-submits ?sql=... (name=sql). Checked cancels it.
+    [ ] The plain "Run SQL" button also submits the current editor text as sql=.
+    [ ] Escape fires "editor-escape".
+    [ ] Reset button restores the initial document (form reset).
+    [ ] Format button reformats via window.sqlFormatter (loaded below).
+    [ ] Read-only toggle disables editing.
+    [ ] Point schema-url at a bad URL (edit source) -> editor still works,
+        keyword-only completion, a console.warn appears.

 Permissions
 ===========
 
+Datasette's permissions system is built around SQL queries. Datasette and its plugins construct SQL queries to resolve the list of resources that an actor cas access.
+
 The key question the permissions system answers is this:
 
     Is this **actor** allowed to perform this **action**, optionally against this particular **resource**?
 
-Every permission decision can be understood in terms of those three values. Datasette implements the decisions using SQL, but you do not need to understand the generated SQL to configure or debug permissions.

 **Actors** are :ref:`described above <authentication_actor>`.

 How permissions are resolved
 ----------------------------
 
-Permission rules describe an effect (``allow`` or ``deny``) at one of three levels:
-
-``resource``
-    A specific child resource, such as the ``analytics/sales`` table.
-
-``parent``
-    A parent resource, such as the ``analytics`` database. A parent rule also applies to its child resources.
-
-``global``
-    Every resource for that action.
-
-Datasette resolves matching rules from most specific to least specific:
-
-#. Resource rules take precedence over parent and global rules.
-#. Parent rules take precedence over global rules.
-#. If both allow and deny rules match at the same level, deny takes precedence.
-#. If no rule matches, access is denied.
-
-This means a resource-level allow can provide an exception to a parent-level deny. It also means that two plugins which disagree at the same level resolve to deny.

+Datasette performs permission checks using the internal :ref:`datasette_allowed`, method which accepts keyword arguments for ``action``, ``resource`` and an optional ``actor``.
 
 ``resource`` should be an instance of the appropriate ``Resource`` subclass from :mod:`datasette.resources`—for example ``InstanceResource()``, ``DatabaseResource(database="...``)`` or ``TableResource(database="...", table="...")``. This defaults to ``InstanceResource()`` if not specified.

-
-* Every matching allow and deny rule, with its source and reason.
-* The winning resource, parent or global scope.
-* Rules ignored because a more specific rule matched, or because a deny won at the same scope.
-* Actor restriction allowlists that included or excluded the resource.
-* Additional actions required by the requested action.

 Changelog
 =========
 
-.. _v1_0_a37:
-
-1.0a37 (2026-07-14)
--------------------
-
-Performance improvement for SQL-backed permission checks, plus an improved permission debugging interface.
-
-- SQL used to resolve permission checks now aggregates permission rules before joining them to resources, improving performance on instances with large schemas. (:issue:`2832`)
-- The :ref:`PermissionCheckView` permission debugger now explains why a decision was allowed or denied, including the matching rules. The interactive form can also test a hypothetical actor supplied as JSON, and the :ref:`permissions documentation <authentication_permissions_explained>` now describes resolution rules in more detail. (:issue:`2841`)
-- :ref:`db.execute_write(sql, ..., transaction=True) <database_execute_write>` has a new ``transaction=`` parameter, which can be set to ``False`` for statements such as ``VACUUM`` that cannot run inside a transaction. Write tasks now start their transactions using ``BEGIN IMMEDIATE``, which also ensures that writes are rolled back if the task fails. (:issue:`2831`)
-- Refreshing a database's schema in Datasette's internal catalog is now performed as a single atomic operation. (:issue:`2831`)
-- Fixed schema introspection, table pages, facets and table counts for tables with names containing a ``]`` character. Thanks, `TowyTowy <https://github.com/TowyTowy>`__. (:issue:`2431`, :pr:`2846`)
-- ``/-/plugins.json`` once again returns a top-level JSON array of plugin objects, reverting the object envelope introduced in 1.0a36. This should fix a large number of trivial test failures in existing plugins. (:issue:`2842`, :pr:`2843`)

+----------------------

+inline editor schema on the SQL query page. A request that fails either check
+receives a ``403`` JSON error that does not reveal any table or column names.
+
+The response is a neutral structure - a ``database`` name and a list of
+``tables``, each with a ``view`` flag (``true`` for SQL views) and a list of
+``columns`` carrying the SQLite declared ``type`` (an empty string when the
+column has no declared type):
