In `@apps/meteor/server/startup/migrations/v336.ts`:
- Around line 12-18: The current predicate used to find targetIndex via
indexes.find(...) is too permissive and may match compound indexes that merely
contain roomId/userId/messageId; update the predicate for targetIndex to ensure
the index key exactly equals the legacy key shape and order and that
index.unique === true (e.g., compare Object.keys(idx.key) and the values/order
or JSON.stringify on the key object against the exact {
roomId:1,userId:1,messageId:1 } shape, and check idx.unique === true) so only
the exact legacy unique index is selected for dropping.
- Around line 4-24: The migration file (v336) registers itself via addMigration
but isn't imported by the migrations loader, so add an import for the module
that defines the v336 migration (the same place you import './v335') so the
side-effect registration runs; locate the migrations loader that currently
imports ./v335 and add the equivalent import for v336 (i.e., import './v336') so
the migration is registered and executed.

File: apps/meteor/app/lib/server/functions/cleanRoomHistory.ts:146-149
Timestamp: 2026-04-18T12:32:50.305Z
Learning: In `apps/meteor/app/lib/server/functions/cleanRoomHistory.ts` (PR `#38623`), the read-receipt cleanup (both `ReadReceipts.removeByMessageIds` and `ReadReceiptsArchive.removeByMessageIds`) is intentionally only performed in the limited prune path (`limit && selectedMessageIds`). The unlimited/delete-all path (`limit === 0`) deliberately skips cleaning up orphaned read receipts in both hot and cold storage — this is by design. Do not flag this as a bug or missing cleanup in future reviews.

File: apps/meteor/app/api/server/v1/push.ts:85-97
Timestamp: 2026-03-14T14:58:58.834Z
Learning: In RocketChat/Rocket.Chat, the `push.token` POST/DELETE endpoints in `apps/meteor/app/api/server/v1/push.ts` were already migrated to the chained router API pattern on `develop` prior to PR `#39625`. `cleanTokenResult` (which strips `authToken` and returns `PushTokenResult`) and `isPushTokenPOSTProps`/`isPushTokenDELETEProps` validators already exist on `develop`. PR `#39625` only migrates `push.get` and `push.info` to the chained pattern. Do not flag `cleanTokenResult` or `PushTokenResult` as newly introduced behavior-breaking changes when reviewing this PR.

Timestamp: 2026-03-11T22:04:20.529Z
Learning: In `apps/meteor/client/views/room/body/hooks/useHasNewMessages.ts`, the `msg.u._id === uid` early-return in the `streamNewMessage` handler is intentional: the "New messages" indicator is designed to notify about messages from other users only. Self-sent messages — including those sent from a different session/device — are always skipped, by design. Do not flag this as a multi-session regression.

Timestamp: 2026-01-17T01:51:47.764Z
Learning: In packages/core-typings/src/cloud/Announcement.ts, the AnnouncementSchema.createdBy field intentionally overrides IBannerSchema.createdBy (object with _id and optional username) with a string enum ['cloud', 'system'] to match existing runtime behavior. This is documented as technical debt with a FIXME comment at apps/meteor/app/cloud/server/functions/syncWorkspace/handleCommsSync.ts:53 and should not be flagged as an error until the runtime behavior is corrected.

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.

Description
Adds a database migration to remove the legacy unique index on
(roomId, userId, messageId)from theread_receiptscollection.Why
The unique index was removed from the model as part of changes where
uniqueness is now handled via the
_idfield. However, this index may stillexist in databases from older versions, causing conflicts and potential
duplicate key errors during operations like archiving.
