- Discord/voice: leave Discord voice off for text-only configs unless `channels.discord.voice` is explicitly configured, avoiding default `GuildVoiceStates` traffic and idle gateway CPU pressure for bots that do not use `/vc`. Fixes #73753; refs #74044. Thanks @sanchezm86 and @SecureCloudProjO.

- Discord/voice: rerun configured voice auto-join after Discord gateway RESUMED events and ignore already-destroyed stale voice connections during reconnect cleanup, so health-monitor account restarts can rejoin configured channels. Fixes #40665. Thanks @liz709.

- Plugins/CLI: reuse the cold manifest registry while building plugin status and inspect reports, so large configured plugin sets no longer rediscover the bundled/plugin registry once per inspect row. Thanks @vincentkoc.

- Gateway/install: drop stale version-manager and package-manager PATH entries preserved from old service files during `gateway install --force` and doctor repair, so the repair path no longer recreates `gateway-path-nonminimal` warnings. Fixes #75220. Thanks @renaudcerrato and @aaajiao.

- Discord/voice: lengthen the default voice join Ready wait, add configurable `voice.connectTimeoutMs`/`voice.reconnectGraceMs`, and warn before destroying unrecovered disconnected sessions so slow Discord voice handshakes and reconnects no longer fail silently. Fixes #63098; refs #39825 and #65039. Thanks @darealgege, @kzicherman, and @ayochim.

- Gateway/health: refresh cached health RPC snapshots when channel runtime state diverges, so Discord and other channel status reads no longer report stale running or connected values until the cache TTL expires. (#75423)

- Gateway/sessions: keep session-store reads from running stale prune and entry-count cap maintenance during startup, so oversized stores no longer block chat history readiness after updates while writes and `sessions cleanup --enforce` still preserve the cleanup safeguards. Fixes #70050. Thanks @tangda18.

- Context Engine: treat assembled prompt as the default authority for preemptive overflow prechecks so engines that return a windowed, self-contained context no longer trigger false hard-fail compactions on huge raw history. Engines whose assembled view can hide overflow risk can opt back into the legacy behavior with `AssembleResult.promptAuthority: "preassembly_may_overflow"`. (#74255) Thanks @100yenadmin.

- Mattermost: refresh current native slash command registrations before accepting callbacks so stale tokens from deleted or regenerated commands stop being accepted without a gateway restart while failed validations stay briefly cached and lookup starts are rate-limited per command, gate each callback against the resolved command's own startup token so a token leaked for one slash command cannot poison another command's failure cache, redact slash validation lookup errors, and add a body read timeout to the multi-account routing path so slow callback senders cannot tie up the dispatcher. Thanks @feynman-hou and @eleqtrizit.

- Security/dotenv: block `COMSPEC` in workspace `.env` so a malicious repo cannot redirect Windows `cmd.exe` resolution, and lock in case-insensitive workspace-`.env` regression coverage for the full Windows shell trust-root family (`COMSPEC`, `PROGRAMFILES`, `PROGRAMW6432`, `SYSTEMROOT`, `WINDIR`). (#74460) Thanks @mmaps.

- Gateway/install: drop stale version-manager and package-manager PATH entries preserved from old service files during `gateway install --force` and doctor repair, so the repair path no longer recreates `gateway-path-nonminimal` warnings. Fixes #75220. (#75440) Thanks @leonaIee, @renaudcerrato, and @aaajiao.
