Summary by CodeRabbit

Chores
- Standardized logging across federation and enterprise components to use structured messages with consistent fields.
- Unified error-variable naming and improved contextual details in error logs for better observability.
- Minor wording fixes in logged messages for consistency.
- Added a small validation that tightens room-creation checks to surface errors earlier.

Walkthrough

This PR standardizes logger usage across the codebase by converting plain string/positional logger calls to structured object logs (with msg and contextual fields) and renames catch variables from error to err for consistency; one assertion was added in federation DM room creation.

Changes

Cohort / File(s)	Summary
Livechat & priorities `apps/meteor/ee/app/livechat-enterprise/server/api/lib/priorities.ts`	Replaced string logger with structured object `{ msg, priorityId, result }` on Mongo update failure.
LDAP manager `apps/meteor/ee/server/lib/ldap/Manager.ts`	Converted multiple logger calls to structured `{ msg, ...context }` payloads (channel, username, roomIds, etc.).
Merge contacts & startup `apps/meteor/ee/server/patches/mergeContacts.ts`, `apps/meteor/ee/server/startup/federation.ts`	Switched debug/error logs to structured objects; renamed catch variable to `err`.
Email IMAP interceptor `apps/meteor/server/email/IMAPInterceptor.ts`	Replaced string template logs with structured `{ msg, user, inboxId, err }` across ready/error/retry paths.
Message hooks `apps/meteor/server/services/messages/hooks/BeforeSaveBadWords.ts`	Renamed catch var to `err`, fixed typo ("Erorr" → "Error"), and moved logs to structured `{ msg, err }`.
Settings / fingerprint `apps/meteor/server/settings/misc.ts`	Converted two-argument logger calls to single structured object with `msg` and `fingerprint`.
Federation — core & events `ee/packages/federation-matrix/src/FederationMatrix.ts`, `.../events/edu.ts`, `.../events/member.ts`, `.../events/message.ts`, `.../events/reaction.ts`	Standardized debug/warn/error logs to structured objects, renamed catch vars to `err`; added assertion in `createDirectMessageRoom` for creator presence.
Federation API & media service `ee/packages/federation-matrix/src/api/_matrix/invite.ts`, `ee/packages/federation-matrix/src/services/MatrixMediaService.ts`	Converted error logs to structured objects `{ msg, err }` and normalized catch variable naming.
License emitter `ee/packages/license/src/events/emitter.ts`	Renamed catch vars to `err` and enhanced error logs to include contextual fields (module, behavior, limit) in structured payloads.

Poem

🐰 I hopped through logs to make them bright,
Swapping strings for objects, tidy and light,
"msg" leads the chorus, context in tow,
Errors now whisper the things we should know.
Hooray — the rabbit leaves cleaner trails tonight! 🥕

🧹 Recent nitpick comments

apps/meteor/ee/server/lib/ldap/Manager.ts (1)
225-226: Optional: Consider converting remaining string-interpolated logs for consistency.

Several other log statements in this file still use string interpolation (e.g., lines 225, 267-269, 468) while this PR converts only some logs to structured format. For full consistency, these could be addressed in a follow-up.

Example for this line:
-			logger.debug(`Advanced Sync failed for user: ${dn}`);
+			logger.debug({ msg: 'Advanced Sync failed for user', dn });

Timestamp: 2025-10-28T16:53:42.761Z
Learning: In the Rocket.Chat federation-matrix integration (ee/packages/federation-matrix/), the createRoom method from rocket.chat/federation-sdk will support a 4-argument signature (userId, roomName, visibility, displayName) in newer versions. Code using this 4-argument call is forward-compatible with planned library updates and should not be flagged as an error.

apps/meteor/ee/server/lib/ldap/Manager.ts (4)

362-383: LGTM!

The structured logging changes in createRoomForSync are well-formed and include appropriate contextual properties (channel, roomOwner) for debugging LDAP channel synchronization issues.

440-450: LGTM!

The structured logging changes provide useful context for debugging channel sync operations, including roomId, username, and userChannelName where appropriate.

542-542: LGTM!

The structured log appropriately includes the unmappedLdapGroups array, which will be valuable for administrators troubleshooting LDAP group mapping issues.

703-703: LGTM!

The structured log includes the user count which provides useful metrics for LDAP synchronization monitoring.
