The server validates settings and enforces per-user rolling quotas with Redis. New status and reset actions expose quota state. The client adds configuration controls, countdown feedback, blocked send paths, error handling, and localized text. Group slow mode
SDK visibility and modal layout
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This change adds server-enforced slow mode, client countdowns, bot exemptions, and a status API, but the current implementation can leave settings or quotas inconsistent, show incorrect blocking state, throttle exempted bots, and accept invalid status requests. The PR is not merge-ready until these bounded correctness and integration issues are addressed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Use a server-derived remaining duration for the countdown.
Lines 80-84 subtract browser Date.now() from the server resetAt. Clock drift can clear blocked before the server accepts a message, or keep the input blocked after the quota resets.
Return retryAfterMs or a server timestamp from getSlowModeStatus. Base the local countdown on that value and refresh when it expires.
Based on learnings: “For time-window behavior, account for clock skew between nodes.”

Require both status lookup identifiers.
Line 821 defines the request body object, but it does not require converseId or groupId. Generated clients can send an incomplete body. The service uses both identifiers to authorize the request and locate the panel.

Align the plugin-bot slow-mode contract.
The server currently sets bypassSlowMode to false, so plugin bots consume quota, while the slow-mode settings and translations state that bots are exempt. Either bypass slow mode for plugin bots or update the administrator-facing description and both locale files to state that only system messages are exempt. The current mismatch gives administrators incorrect expectations about configured channel behavior.

Validate slow mode in every panel mutation path.
updateGroupField at Lines 424-485 still accepts fieldName === 'panels' and persists the supplied panels without calling validateSlowMode. A caller with panel-management permission can store invalid slow-mode metadata, which disables enforcement because getGroupPanelSlowMode returns undefined. This path also changes valid slow-mode settings without resetting existing counters.
Route panel replacement through the validated panel actions, or validate every panel and reset counters for each changed text panel before the update completes.

Background
Group text channels need a simple way to slow down repeated messages from the same member. This helps busy channels stay readable and prevents one person from flooding the conversation.
Changes
Testing
Patch includes focused tests for group panel form data, slow mode bypass behavior, and Redis slow mode counter behavior including rolling windows, release on failure, isolation, concurrency, policy reset, and Redis server time.
