Learning: In `apps/meteor/app/apps/server/converters/uploads.ts`, the `room` async handler in `convertToApp` uses non-null assertions (`upload.rid!` and `result!`) intentionally. The data flow guarantees that any upload reaching this point must have a `rid`; if it does not, throwing an error is the desired behavior (fail-fast / data integrity guard). Do not flag these non-null assertions as unsafe during code review.

Learning: In `apps/meteor/app/apps/server/converters/messages.ts`, the `timestamp` handler inside `_convertAttachmentsToApp` uses a non-null assertion (`attachment.ts!`) intentionally. The `ts` property on `MessageAttachment` is optional only to accommodate MessageAttachment creation-time scenarios; by the time `_convertAttachmentsToApp` is called, the message has already been stored and the attachment is guaranteed to have a `ts` value. Do not flag this non-null assertion as unsafe during code review.

Learning: Applies to apps/meteor/tests/e2e/**/*.spec.ts : Use `expect` matchers for assertions (`toEqual`, `toContain`, `toBeTruthy`, `toHaveLength`, etc.) instead of `assert` statements in Playwright tests

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.

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.
