58-61: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueAdded comments conflict with the repo's "no implementation comments" rule.
The new explanatory comments at Lines 58-61, 73-74, and 102 document useful flaky-test reasoning, but the project guideline for Playwright test files is to avoid code comments in the implementation. Consider moving the rationale into the PR description or commit message and keeping the spec comment-free.
As per coding guidelines: "Avoid code comments in the implementation".

Timestamp: 2026-02-24T19:22:48.358Z
Learning: In Playwright end-to-end tests (e.g., under apps/meteor/tests/e2e/...), prefer locating elements by translated text (getByText) and ARIA roles (getByRole) over data-qa attributes. If translation values change, update the corresponding test locators accordingly. Never use data-qa locators. This guideline applies to all Playwright e2e test specs in the repository and helps keep tests robust to UI text changes and accessible semantics.

Learning: In RocketChat e2e tests, avoid using data-qa attributes to locate elements. Prefer semantic locators such as getByRole, getByLabel, getByText, getByTitle and ARIA-based selectors. Apply this rule to all TypeScript files under apps/meteor/tests/e2e to improve test reliability, accessibility, and maintainability.

Timestamp: 2026-02-26T19:25:44.063Z
Learning: In the Rocket.Chat repository, do not reference Biome lint rules in code review feedback. Biome is not used even if biome.json exists; only reference Biome rules if there is explicit, project-wide usage documented. For TypeScript files, review lint implications without Biome guidance unless the project enables Biome rules.

Timestamp: 2026-02-26T19:25:44.063Z
Learning: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

Timestamp: 2026-03-06T18:10:15.268Z
Learning: In tests (especially those using testing-library/dom/jsdom) for Rocket.Chat components, the HTML <code> element has an implicit ARIA role of 'code'. Therefore, screen.getByRole('code') or screen.findByRole('code') will locate <code> elements even without a role attribute. Do not flag findByRole('code') as invalid in reviews; prefer using the implicit role instead of adding role="code" unless necessary for accessibility.

File: apps/meteor/client/components/CreateDiscussion/CreateDiscussion.tsx:121-149
Timestamp: 2026-05-06T12:21:44.083Z
Learning: Field wrappers in rocket.chat/fuselage-forms (Field, FieldLabel, FieldRow, FieldError, FieldHint) auto-create htmlFor/id associations, aria-describedby, and role="alert" for errors. Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

62-64: Block-local precondition correctly removes the racy cross-block coupling.Restoring
preview-c-roomto['admin', 'user', 'anonymous']in this block's owntest.beforeAllmakes the scenario self-contained rather than depending on the prior describe'safterAll, which matches the payload contract inpreview-public-channel.spec.ts:24and is the right fix for serial-block flakiness.
75-75: LGTM!
