侧边对话隔离检查失败

Error message

侧边对话隔离检查失败

What it means

After native.Q1 creates the side conversation, remember(sideId) validates that the returned conversation is genuinely a new ephemeral side thread: it must have a truthy id, differ from the parent threadId, and be flagged sideConversation===true and ephemeral===true. Any violation means isolation from the parent thread cannot be guaranteed, so the script throws to prevent writing organizer output into the main thread.

Solutions

1. Update canvas.user.js to a version compatible with the installed Codex build's side-conversation semantics.
2. Verify in devtools what conversation Q1 actually returned (check sideConversation/ephemeral flags) and adapt the validation or the creation call.
3. Roll back Codex to a build where sideConversation/ephemeral flags are set as expected.
4. Abort the organizer flow cleanly and reset session.phase so the parent thread is not polluted; retry after the script/app is fixed.

Example fix

// before
if(!sideId||sideId===threadId||side?.sideConversation!==true||side?.ephemeral!==true)throw Error('侧边对话隔离检查失败');
// after
if(!sideId||sideId===threadId||side?.sideConversation!==true||side?.ephemeral!==true){console.warn('side isolation check failed',{sideId,side});await cleanup(session);throw Error('侧边对话隔离检查失败');}

const side=manager.getConversation(resultId);
const isolated=!!sideId&&sideId!==threadId&&side?.sideConversation===true&&side?.ephemeral===true;
if(!isolated)await cleanupSide(resultId);

const isIsolatedSide=(side,sideId,threadId)=>!!sideId&&sideId!==threadId&&side?.sideConversation===true&&side?.ephemeral===true;

try{await remember(resultId);}catch(e){if(e.message==='侧边对话隔离检查失败'){await resetSession(session);notify('side thread isolation failed; parent thread untouched');return null;}throw e;}

When it happens

Trigger: The Q1 callback/creation result yields a conversation that is missing, shares the parent thread's id, or lacks sideConversation/ephemeral flags — e.g. the Codex build's composer callback forked parent history into a normal conversation instead of creating a blank side task (the documented failure mode in the source comment).

Common situations: Codex version where thread/start ignores the sideConversation option and falls back to forking all parent history; flags renamed in a client update; creation returned the parent conversation itself.
