From f5b2f099d9a25aa91a10ee28f120f033ee096e72 Mon Sep 17 00:00:00 2001 From: mchwang Date: Sat, 26 Sep 2026 01:20:32 -0700 Subject: [PATCH 01/11] Run Ask in the lane D agent container Ask used to run the claude/codex CLI on the host with each CLI's own restrictions, an interim exception to R1. It now uses lane D's invocation boundary in the read-only "questions" phase: a clone of the reviewed snapshot head at /work, no commands, vendor-only network, and no other host files. There is no host fallback. - runner/question-container.ts: build image, clone, allocate bounded storage, capture, start the Claude/Codex adapter; release storage only after the invocation settles. Deps are injectable for unit tests. - runner/question-worker.ts: lane D setup is synchronous, so a worker thread owns it and the review server stays responsive. - runner/question-agent.ts: QuestionWorker bridge; a question settles only when the worker reports the container and storage are gone. - Credentials come from the environment only: CLAUDE_CODE_OAUTH_TOKEN for Claude, CODEBOOST_CODEX_AUTH_FILE or CODEX_HOME/auth.json for Codex. - Provider failures include the vendor's short message (e.g. a 401). - test/agent-question.test.ts runs the path on real Docker (Agent isolation workflow); its live case needs the auth-probe credentials. - Plan, README, Settings copy and implementation docs updated; the R1 exception is closed.

none are dropped. - Removal commands list only resources that still exist, so a missing keeper no longer blocks volume removal.

fix CI env dependency - The bridge creates one Ask root per worker (/codeboost-ask-*), records it before the worker starts, and runs the worker with it as TMPDIR, so the reviewed clone, lane D's input directory and its Codex auth copy all live inside it. The root is deleted after the thread stops (clean shutdown, crash or abandon); otherwise the next check deletes it, and Ask stays off while an earlier root remains. - The record accepts only direct children of the real temp directory named codeboost-ask-XXXXXX, so a lookalike path elsewhere is refused instead of deleted. - Test fix: the bridge checks sign-in before asking, so the stub worker now gets its own Codex auth file instead of depending on ~/.codex.
