@@ -85,6 +85,7 @@ Docs: https://docs.openclaw.ai
 - Channels/allowlists: remove stale matcher caching so same-array allowlist edits and wildcard replacements take effect immediately, with regression coverage for in-place mutation cases.
 - Gateway/auth: fail closed when local `gateway.auth.*` SecretRefs are configured but unavailable, instead of silently falling back to `gateway.remote.*` credentials in local mode. Thanks @tdjackey.
 - Sandbox/fs bridge: pin staged writes to verified parent directories so temporary write files cannot materialize outside the allowed mount before atomic replace. Thanks @tdjackey.
+- Commands/config writes: enforce `configWrites` against both the originating account and the targeted account scope for `/config` and config-backed `/allowlist` edits, blocking sibling-account mutations while preserving gateway `operator.admin` flows. Thanks @tdjackey for reporting.

 - `bash: true` enables `! <cmd>` for host shell. Requires `tools.elevated.enabled` and sender in `tools.elevated.allowFrom.<channel>`.
 - `config: true` enables `/config` (reads/writes `openclaw.json`). For gateway `chat.send` clients, persistent `/config set|unset` writes also require `operator.admin`; read-only `/config show` stays available to normal write-scoped operator clients.
 - `channels.<provider>.configWrites` gates config mutations per channel (default: true).
+- For multi-account channels, `channels.<provider>.accounts.<id>.configWrites` also gates writes that target that account (for example `/allowlist --config --account <id>` or `/config set channels.<provider>.accounts.<id>...`).
 - `allowFrom` is per-provider. When set, it is the **only** authorization source (channel allowlists/pairing and `useAccessGroups` are ignored).
 - `useAccessGroups: false` allows commands to bypass access-group policies when `allowFrom` is not set.

 - `/new <model>` accepts a model alias, `provider/model`, or a provider name (fuzzy match); if no match, the text is treated as the message body.
 - For full provider usage breakdown, use `openclaw status --usage`.
 - `/allowlist add|remove` requires `commands.config=true` and honors channel `configWrites`.
+- In multi-account channels, config-targeted `/allowlist --account <id>` and `/config set channels.<provider>.accounts.<id>...` also honor the target account's `configWrites`.
 - `/usage` controls the per-response usage footer; `/usage cost` prints a local cost summary from OpenClaw session logs.
 - `/restart` is enabled by default; set `commands.restart: false` to disable it.
 - Discord-only native command: `/vc join|leave|status` controls voice channels (requires `channels.discord.voice` and native commands; not available as text).
