How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

WalkthroughThe pull request documents a preferred order for trait members. It reorders existing hooks, steps, and helpers across multiple traits. It also adds Drupal hooks and step definitions for files, taxonomy terms, nodes, and roles. ChangesTrait ordering and Drupal additions
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR records member-ordering guidance while also changing trait source order. Drupal role setup can still fail for labels containing spaces and can emit warnings when permissions are omitted, so merge should wait for those bounded correctness issues to be fixed or explicitly accepted.

The dominant layout is stated, along with the two parts of it that are firm and the helper-next-to-its-steps variant that is accepted. Reordering an existing trait is ruled out as a change of its own, because docs.php renders steps into STEPS.md in source order, so moving members reorders the published documentation for no runtime gain.
The count of conforming traits is dropped, since it goes stale as traits are added. The claim that reordering members reorders STEPS.md was wrong and is removed: docs.php groups steps by Given, When and Then before rendering, so source order does not reach the generated documentation. That was the stated reason for not sweeping, and it does not hold.
Nineteen traits now place trait composition, constants and properties first, then hooks, then Given, When and Then steps, then other public methods, then protected helpers. Members moved as whole units with their docblocks and attributes, and relative order inside each group is preserved, so every hunk is a move rather than a rewrite. STEPS.md is byte-identical afterwards. FieldTrait is left alone because ordering its steps ahead of the method returning a NodeElement makes Drupal.Classes.UnusedUseStatement report a used import as unused.

| Traits lay their members out in this order: | ||

|
||
| 1. Trait composition (`use`), constants, then properties. | ||
| 2. Hooks (`#[BeforeScenario]`, `#[AfterStep]` and the like). | ||
| 3. `Given` steps, then `When` steps, then `Then` steps. | ||

| Keep to it when adding a member or writing a new trait. Reordering an existing trait to match is a safe change: [STEPS.md](STEPS.md) groups steps by `Given`, `When` and `Then` itself, so member order in the source does not affect the generated documentation. |

Document the accepted helper co-location variant.

Use prerequisite wording for this Given step.
Change the step to describe an existing role, for example the role :role_name exists with the permissions :permissions. The current phrase does not use a prerequisite verb.
As per coding guidelines: “Given steps should define test prerequisites, use words like exists or have.”

Drupal user role config entity ID validation allowed characters Role::baseFieldDefinitions role ID
💡 Result:
In Drupal, the machine name (ID) of a user role is subject to validation constraints defined in the configuration schema [1]. As of recent Drupal versions, the user.role.* configuration entity uses the machine_name data type for its id field [1][2]. The machine_name configuration schema type imposes the following default validation constraints: - Regex: /^[a-z0-9_]+$/ (only lowercase alphanumeric characters and underscores are allowed) [2] - Length: Maximum of 64 characters [3][2] These constraints ensure that role IDs remain consistent and portable across different database backends and configuration storage systems [3]. While the Role entity class (Drupal\user\Entity\Role) does not contain hardcoded validation logic within its baseFieldDefinitions method, the entity's configuration schema (user.schema.yml) enforces these rules during configuration save operations and validation routines [4][5][1]. Developers creating roles programmatically should ensure IDs adhere to these restrictions to avoid validation errors, as configuration entities are typically immutable once created regarding their machine name [6]. Attempting to save a role with characters outside this set (such as uppercase letters, spaces, or special characters) will trigger a validation failure [6].

Normalize and validate the role ID before loading it.

Parked for the 4.x line. The reorder is a large structural move across nineteen traits, so it is held back from a minor release and retargeted to the 4.0 milestone along with issue #724. Rebased onto the current main and green apart from CI on the latest head, so it can be picked up as-is when 4.x opens. |

Closes #724
Summary
#724 asks for the member ordering to be settled. It is settled both ways: the layout is written down, and the traits are reordered to match it.
The order is trait composition, constants and properties first, then hooks, then
Given,WhenandThensteps, then other public methods, then protected helpers.A claim in the issue that turned out to be wrong
#724 argues against a sweep on the grounds that
docs.phprenders steps intoSTEPS.mdin source order, so reordering members would reorder the published documentation and produce a large second diff for no runtime gain.That is not what
docs.phpdoes. It sorts steps byGiven,WhenandThenbefore rendering, so member order in the source never reaches the generated documentation.STEPS.mdis byte-identical after reordering all nineteen traits, confirmed byahoy lint-docsreporting no changes.The main argument against sweeping does not hold, so the sweep is done.
How the reorder was made
A tokenizer-driven script moves each member as a whole unit, carrying its docblock and attributes, and preserves relative order inside each group. Every hunk is therefore a move rather than a rewrite.
Boundaries come from PHP's tokenizer rather than from counting braces in the text. A first attempt counted braces and corrupted
KeyboardTrait, whose heredoc carries JavaScript containing braces that are not structural. Each reordered file was then checked to parse and to expose an identical set of methods, properties and composed traits.The one exclusion
FieldTraitis left in its original order.Drupal.Classes.UnusedUseStatementstops recognising an imported class whose first use follows a PHP 8 attribute. In the original order the method returning aNodeElementsits above every step attribute; in the canonical order the step attributes come first, and the linter then reports theNodeElementimport as unused although three usages remain. Any canonical ordering puts step attributes ahead of public non-step methods, so the file cannot be ordered without tripping it, and working around a third-party sniff by editingphpcs.xmlis not on the table.That exclusion is recorded in
CONTRIBUTING.mdso it does not read as an oversight.Changes
CONTRIBUTING.md: new "Member ordering within a trait" section stating the layout, theSTEPS.mdfact, and theFieldTraitexclusion. No count of conforming traits, since that goes stale as traits are added.Verification
ahoy lint,ahoy test-unitandahoy lint-docsall pass, andSTEPS.mdis unchanged.Behat suites covering the reordered traits pass: element 95 scenarios, xml 87, json 52, path 27, link 20, modal 21, responsive 19, accessibility 9, email 55, user 51, file 12, watchdog 13, queue 6, content block 13, date 5, file download 24.
drupal_contentanddrupal_taxonomyeach report two failures locally, in the vertical-field-format scenarios. Those same two scenarios fail identically on unmodifiedHEAD, so they pre-date this change and are a local fixture artefact rather than a regression.Before / After
