`109-109`: **Avoid inline lint-disable comments in implementation code.** Prefer a config-level override (or shared declaration-file convention) for this augmentation pattern instead of inline suppression comments. As per coding guidelines: "Avoid code comments in the implementation".

Inline comments: In `@apps/meteor/app/api/server/v1/mailer.ts`: - Around line 27-28: The OpenAPI change added nullable: true to the request schema fields dryrun and query which expands the contract to accept explicit nulls; revert those schema entries in the mailer.ts request/body definition so dryrun and query remain optional but not nullable (remove the nullable: true key for the dryrun and query properties in the schema object), ensuring validation semantics for dryrun and query are preserved. --- Nitpick comments: In `@apps/meteor/app/api/server/v1/mailer.ts`: - Line 109: Remove the inline eslint-disable comment in apps/meteor/app/api/server/v1/mailer.ts and instead handle the augmentation exception at configuration or declaration-file level: either add a targeted override in the shared ESLint config (.eslintrc) to allow `@typescript-eslint/naming-convention` and `@typescript-eslint/no-empty-interface` for declaration/augmentation files, or move the augmentation into a shared .d.ts declaration file (e.g., types/global.d.ts) where you can document and scope the exception without inline suppression; update references to the augmentation so the file no longer contains the inline "eslint-disable-next-line" comment. ```

Module augmentations in apps/meteor (e.g., declare module 'rocket.chat/rest-typings') are not visible when compiling packages/ddp-client in isolation, which is why legacy SDK methods that depend on OperationResult types for OpenAPI-migrated endpoints must remain commented out. ``` **Applied to files:** - `.changeset/migrate-mailer-openapi.md` - `apps/meteor/app/api/server/v1/mailer.ts`

`49-104`: **Route migration preserves the important guards and behavior.** Auth requirements, `send-mail` permission, rate limiting, and handler flow are retained while adding explicit response schemas. --- `106-111`: **Module augmentation is safe for isolated package compilation.** Verification confirms no active legacy SDK typing depends on the migrated mailer endpoints. The module augmentation in `apps/meteor` will not cause typing issues when `packages/ddp-client` compiles in isolation, as no legacy SDK methods reference these endpoints.

.changeset/migrate-mailer-openapi.md (1)
`2-3`: **The review comment is based on an incorrect premise.** Mailer types were never exported from `@rocket.chat/rest-typings`. The changeset describes a refactoring of endpoint implementation within `apps/meteor` (migrating from `addRoute` to the chainable `.post()` pattern), not a removal of public types from rest-typings. Since the rest-typings public API surface is unchanged, the `patch` level is appropriate. > Likely an incorrect or invalid review comment.
