 ### Fixes
 
+- Codex/Lossless: keep Codex explicit compaction on native app-server threads while allowing Lossless through the context-engine slot; `openclaw doctor --fix` now migrates legacy `compaction.provider: "lossless-claw"` config to `plugins.slots.contextEngine`.
 - Cron: load runtime plugins before isolated cron model and delivery resolution so external channels can be selected for scheduled runs. (#82111) Thanks @medns.
 - Twitch: keep gateway accounts running until shutdown instead of treating successful monitor startup as a clean channel exit, preventing immediate auto-restart loops. Fixes #60071. (#81853) Thanks @edenfunf.
 - Agents/auto-reply: honor `agents.defaults.silentReply` and per-surface group silent-reply policy when generic agent-run failure fallbacks decide whether to send visible fallback text. Fixes #82060. (#82086) Thanks @taozengabc.

 - macOS/screen snapshots: reject malformed `screen.snapshot` params before capture, bound base64 results against the projected `node.invoke.result` frame, and preserve stable caller-facing errors for oversized payloads and capture failures. Fixes #68181. Thanks @shaun0927 and @BunsDev.
 - Config/doctor: rotate capped `.clobbered.*` repair snapshots by artifact timestamp so repeated repairs keep the newest forensic copy instead of preserving only the first capped set. (#82012) Thanks @Kaspre.
 - Telegram: initialize the bot before isolated polling drains spooled updates so default isolated polling no longer retries every update with `Bot not initialized` and stalls replies. Fixes #81973. (#81975) Thanks @neeravmakwana.
+- Codex app-server: keep Codex-runtime compaction on native Codex threads, warn when stale OpenClaw compaction summarizer overrides are ignored, and let doctor remove those unsupported overrides, avoiding public OpenAI Responses summarization with Codex OAuth tokens. Fixes #82008. (#82027) Thanks @pashpashpash.
 - Telegram: apply method-aware Bot API request timeouts to direct message/action clients so `openclaw message delete --channel telegram` no longer waits on grammY's 500-second default when the API request wedges. Fixes #81908. Thanks @DashLabsDev.
 - Cron: treat attempt dispatch and assembled context as execution-start milestones so isolated agent jobs that have reached backend dispatch are governed by their configured job timeout instead of the 60s pre-execution watchdog. Fixes #81368. (#81871) Thanks @alexph-dev.
 - Doctor/auth: warn about stale per-agent OAuth auth profile shadows and let `openclaw doctor --fix` remove the local shadow so agents inherit the fresher main-agent credential.

+Do not set `compaction.model` or `compaction.provider` on Codex-backed agents.
+Codex owns compaction through its native app-server thread state, so OpenClaw
+ignores those local summarizer overrides at runtime and `openclaw doctor --fix`
+removes them when the agent uses Codex.

+Lossless remains supported as a context engine. Configure it through
+`plugins.slots.contextEngine: "lossless-claw"` and
+`plugins.entries.lossless-claw.config.summaryModel`, not through
+`agents.defaults.compaction.provider`. `openclaw doctor --fix` migrates the old
+`compaction.provider: "lossless-claw"` shape to the Lossless context-engine slot
+when Codex is the active runtime.
