An unreadable record, a Docker daemon that cannot answer in time, or a worker that does not report + at shutdown keeps Ask off. Allocations beyond the record's cap of 100 count as unidentified, never dropped; Ask + roots are never dropped, and recording one past the cap is refused. Any labelled resource that is not part of a + still-listed allocation keeps the unidentified marker until none remain. Removal goes through D only once D has + recovery handles (#51 item 4). +- Host copies are owned through one Ask root per worker, `/codeboost-ask-XXXXXX`. The bridge creates it and + 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 land inside it. The root is deleted, read-only directories included, + once the worker thread has stopped (clean shutdown, crash or abandon); if that fails, or the process is killed, + the next check deletes it. Ask stays off while an earlier root remains. The record accepts only direct children + of the real temp directory with that exact name. +- Each Ask root carries an `.owner` stamp naming its lock, written before the folder appears under its Ask name. The + first check of a process also looks for `codeboost-ask-*` folders the record does not list, for example after the + database was renamed and its record stayed behind. It deletes only folders this user owns whose stamp names a lock + in the private lock directory and whose owner lock is free. It leaves folders whose owner is still running, and + folders with a missing, malformed or foreign stamp, because Ask did not provably create those. +- If storage setup itself fails and D cannot confirm its own cleanup, D returns no handle and Ask cannot tell which + resources were left. Ask stays off for the rest of the session, and the record counts the failure. After a + restart, Ask stays off while any container, volume or network labelled `io.codeboost.allocation`, + `io.codeboost.invocation` or `io.codeboost.egress` exists. Caller-provided + allocation IDs (#51 item 3) would let Ask name these resources instead. +- One process at a time runs Ask for a review. The lock is an exclusive SQLite transaction on a lock file keyed by + the database file's identity (device and inode), in a private directory (`/codeboost-asklocks-`, mode + 0700, checked to be owned by you). A lock path that is a symlink is refused, never followed. It is an OS file lock that the operating + system releases when its process ends, so every spelling and every later name of the database, including an + atomic rename while a server runs, finds the same lock. It is taken before the scan and kept until the worker + and any startup scan still in flight have finished. Only the holder scans, starts a worker or writes the + record. The record itself is kept next to the database's canonical path (`realpath`), so relative, +absolute and symlinked spellings share them. A database with other hard links is refused. Separating different + reviews that share one Docker daemon needs runner identity labels (#51 item 3), and the general single-runner + lock is F1d (#59). +- The first question of each process runs that scan even without a record, because a process killed before it + could write one leaves no record. Until resources carry the runner's identity (#51 item 3), another codeboost + process running Ask at the same moment also keeps this one off. +- Lane D's settlement can retry cleanup without limit (#51 item 1). Abandonment happens once: a crash, a watchdog and shutdown all wait on + the same bounded termination. A question not settled 30 seconds after its + deadline, or still settling after the 20-second shutdown grace period, makes the bridge abandon the worker. It + records unknown leftovers, waits up to 15 seconds for the worker thread to stop (a synchronous Docker or Git call + finishes first), then rejects the waiting questions, so shutdown cannot hang on D. A worker that does not answer + the final release request at shutdown goes through the same bounded path. If the thread is still busy + after that wait, its ownership is already durable (unknown leftovers and the recorded root) and no new question is + admitted; the root is deleted as soon as the thread stops. After any abandonment the review lock is kept until the + process exits: Docker CLI children the thread started can outlive it and cannot be awaited until lane D exposes + process groups (#51 item 5). +- If the worker itself crashes, its containers and storage may still exist. The bridge does not start a + replacement worker, and it records the crash at once as unidentified leftovers. After a restart, Ask stays off + while any container, volume or network labelled `io.codeboost.allocation`, + `io.codeboost.invocation` or `io.codeboost.egress` exists. Reclaiming those leftovers after a crash or restart + needs lane D's labelled resources and scoped recovery (#51, item 4), which do not exist yet. + +`test/agent-question.test.ts` runs this path +against real Docker; its live case, like the vendor probes above, needs `CODEBOOST_RUN_AUTH_PROBES=1` and +`CLAUDE_CODE_OAUTH_TOKEN`. + ## Limits of this gate - CI does not run the live vendor probes.

It runs in the lane D container in the read-only "questions" phase, with a clone of the reviewed head at `/work`; Claude needs `CLAUDE_CODE_OAUTH_TOKEN` and Codex its `auth.json` (see `agent-isolation.md`, "First consumer: Ask"). The rest of this paragraph describes the original host adapter. + The CLI adapter runs without a shell in a fresh temporary directory. Claude uses safe mode with no tools and no session persistence. Codex uses an ephemeral, read-only session with user config/rules ignored, shell/apps/plugins/hooks/memory/delegation disabled, and web search disabled. These are restricted question adapters, not the future containerized code-running agent environment. Stdout and answer sizes are bounded; raw process logs and credentials are not returned to the browser.

Both installed providers passed live connection checks. A separate copy of PR #597's review database passed a real Settings → Ask → saved Claude answer browser test; the user's review state and source checkout were unchanged.
