Greptile Summary

This PR implements "Joins v2" — a new cross-collection join query feature for the Databases API — along with a breaking change to the Query::select() signature (single attribute per call instead of an array), a new V22 backward-compatibility request filter, and a version bump to 1.10.0. The core join logic (resolving join collection IDs, registering them with the database adapter) is well-structured, and the defensive guards added to app/init/database/filters.php are a clean improvement. However, several blocking issues prevent this from being merge-ready:

• Development branch dependencies: composer.json pins utopia-php/database to dev-joins8 and utopia-php/migration to dev-joins. These must be replaced with stable tagged releases before the PR can land on 1.8.x.
• Empty PHP files committed: app/controllers/api/teams.php, src/Appwrite/Platform/Modules/Databases/Http/DocumentsDB/Collections/Documents/Logs/XList.php, src/Appwrite/Platform/Modules/Databases/Http/DocumentsDB/Collections/Logs/XList.php, src/Appwrite/Platform/Modules/Databases/Http/VectorsDB/Collections/Create.php, and src/Appwrite/Platform/Modules/Databases/Http/VectorsDB/Collections/Logs/XList.php are all 0-byte files. These will cause fatal errors or silent route omissions at runtime.
• phpunit.xml stopOnFailure/stopOnError set to true: Halts the suite at the first failure and masks subsequent broken tests in CI.
• Types.php hardcodes Database::VAR_INTEGER: The DocumentsValidator is constructed with an integer ID type regardless of the active adapter, which is already known to break MongoDB sequence queries (as acknowledged by the adapter-conditional assertion in testQueryBySequenceType).
• V22 filter silently injects internal attributes: expandSelects appends $id, $sequence, $permissions, $createdAt, $updatedAt for every namespace level when any non-wildcard field is selected, potentially exposing fields the caller did not request.
• Test retry count reduced: Scope.php drops $maxRetries from 5 to 1, increasing flakiness under parallel test execution.

Confidence Score: 1/5

• Not safe to merge — development-branch dependencies, multiple empty PHP files, and hardcoded adapter-specific logic are blocking issues.
• Multiple P0 blockers are present: the entire dependency tree for utopia-php/database and utopia-php/migration points at untagged development branches, five committed PHP files are completely empty (which will cause runtime fatals or silent route loss), and phpunit.xml is configured to hide downstream test failures. The new join feature logic itself looks architecturally sound, but the PR is clearly in a work-in-progress state and is not ready for the 1.8.x production branch.
• composer.json (dev deps), app/controllers/api/teams.php (empty), the four empty files under Databases/Http/DocumentsDB and VectorsDB, phpunit.xml (stop-on-failure), and src/Appwrite/Utopia/Database/Validator/Queries/Types.php (hardcoded VAR_INTEGER).
