- Codex app-server: report Codex-native tool execution to diagnostics so long-running native `bash`, web, file, and MCP tools no longer look like stale embedded runs to the watchdog. (#80217)

- Codex app-server: refresh Codex account rate limits after subscription usage-limit failures so Discord and other channel replies can show the next reset time instead of saying Codex returned none. Thanks @pashpashpash.

- Agents/auth: let Codex-backed OpenAI agent turns use `auth.order.openai` entries for Codex-compatible OAuth and API-key profiles while keeping existing `openai-codex` profile ordering valid.

- Codex app-server: emit async `after_tool_call` observations for native tool completions not covered by the native hook relay so observability plugins can record Codex-native tools. (#80372) Thanks @VACInc.

- Tasks: route group and channel task completions through the requester session so the parent agent can send the visible summary instead of stopping at a generic task-status line. Fixes #77251. (#77365) Thanks @funmerlin.

- Telegram: preserve blank lines between manually indented bullet blocks and following numbered sections in rendered replies. Fixes #76998. Thanks @evgyur.

- Agents/sandbox: allow read-only sandbox sessions to read the `/agent` workspace mount while keeping write/edit/apply_patch workspace-only guarded, restoring `read /agent/...` for `workspaceAccess: "ro"`. Fixes #39497. Thanks @stainlu and @teosborne.
