The pull request adds column-scoped collection permissions, including parsing, metadata storage, validation, authorization checks, and result masking. It also updates grants when attributes or relationships change and adjusts MariaDB index cleanup and adapter tests.
Permission strings and builders support named columns. Collection metadata stores scoped grants separately from role-only grants. A scoped toggle is available and included in snapshots. Collection validation checks permission types and column keys.
Document authorization and result masking src/Database/Trait/Documents.php, tests/e2e/Adapter/Scopes/ColumnPermissionTests.php
Document operations check read and update column grants, reject restricted joins and writes, and mask document results and callbacks.

Attribute and relationship renames update matching grants, and deletions remove them. MariaDB attribute deletion removes indexes containing only the tenant column.

Summary
Metadata fixtures and collection pagination tests/unit/Attributes/CheckAttributeTest.php, tests/unit/Documents/ResolvedCollectionReadTest.php, tests/e2e/Adapter/MongoDBTest.php, tests/unit/State/CoroutineStateTest.php
Attribute-limit fixtures derive their counts from the collection definition. Tests account for the additional collection metadata attribute, and the MongoDB collection-list test gathers results across pages of 100.
Column-scoped read grants can be bypassed through a document-level join or a groupBy aggregate, and existing installs may fail to write collection metadata after upgrade because no migration adds the new column. Wildcard row counts are also wrongly refused for column-scoped readers. Fix these before merging.

Limited by an open critical finding: Gate queries on direct document reads
MariaDB now removes tenant-only indexes left behind after an attribute is dropped in shared-table mode. Schema reconciliation coverage checks index cleanup, composite-index behavior, and reuse of a removed index name.

### Issue 1
src/Database/Trait/Documents.php:592
**Gate queries on direct document reads**
This masks the returned base document, but `getDocument()`'s `readDocument()` path never calls `assertQueryColumns()` or `rejectRestrictedJoins()`. A caller can therefore join from an unrestricted collection into a column-restricted one and receive its hidden fields, or use filters on hidden columns as an oracle; apply the same query gate before this read.

src/Database/Adapter/MariaDB.php
After attribute deletion, removes leftover indexes that contain only the tenant column in shared-table mode.
Add a getDocument() join case to the join-refusal test.
This test covers joins through find() only. The getDocument() path accepts the same join queries and has no column-read check (see the comment on src/Database/Trait/Documents.php Lines 590-594). Add a case: getDocument('columnGrantsJoinOpen', 'o1', [Query::join('columnGrantsJoinBase', 'secret', [Query::on('baseId', '$id')])]) as role any. The case expects a QueryException, or at least no secret.salary key in the result.

Add columnPermissions to existing metadata tables.
Existing SQL metadata tables lack this column. encode() adds it to metadata writes, so collection creation and updates can fail after an upgrade. This also affects metadata writes for schema changes.
Add a migration or reconciliation step for existing metadata tables, including shared tables.

Run the column-read check in getDocument() before readDocument().
fetch(), count() and sum() call assertQueryColumns(), and that call runs rejectRestrictedJoins(). getDocument() calls neither. readDocument() accepts join queries: it authorizes them, decodes them, and returns the joined values as alias.column keys. maskColumns() then uses only the base collection's grants.
Trigger: the base collection has no column grants and the joined collection is column-restricted. Example: getDocument('columnGrantsJoinOpen', 'o1', [Query::join('columnGrantsJoinBase', 'secret', ...)]) as role any. In this case grantedColumns() returns null for the base, and the mask removes nothing. The caller gets secret.salary, which the grants do not cover. find() refuses this same join.
Call checkQueryTypes() first. resolveJoinedCollections() calls getMethod() on every item, so the queries must all be Query objects. assertQueryColumns() returns early when authorization is skipped, so internal reads keep working.

Check grouping columns against read grants.
columnsNamedBy() skips the string values in Query::groupBy(). A caller granted only name can use aggregate('columnGrantsQueries', [Query::groupBy(['salary'])]) to read grouped salary values. A group-only count() can also disclose the number of groups.
Handle grouping values like select values:
