Matches docs/implementation/guarded-merge.md. - Tick T1, T2, T4, T5, T10, T13, T14 with test evidence; point Files lines at core/linking.ts and core/approvals.ts instead of never-created modules. - Mark increment 1 merged; add a lane status table (C, D, K done; E, F, H progress); record decided open questions (issue ranking, AgentDiff). - Add a verified status note for design tasks DT2-DT15; none newly ticked.

Compare both SHAs with the base/head used for attribution, approvals, and validation. If the head changed even when the base did not, reload the history and ledger, recompute links and approval staleness, and return changed or unplanned items to review. Re-run all `cmd:` checks for any head without current passing results. Continue only after the current head satisfies review and validation; do not skip the rule refresh in step 4 even when both SHAs match. 3. If the base has moved, codeboost rebases the PR branch (see below) and pushes it. After every rebase, recompute attribution, segment choices, approval staleness, and all merge blockers for the resulting head. If any item is stale or any foreign/ambiguous segment is new, changed, or still unaccepted/unassigned, stop and return to review even when no owned item's code changed. Only after those blockers are cleared, re-run every plan item's `cmd:` checks on the rebased code, in the container. If the base did not move, keep the current head and the validation requirements from step 2. If any check fails, merging stops and you go back to review (engineering review, O3). Test results are tied to the commit they ran on. Results for any other commit are shown as out of date. 4. codeboost waits for GitHub's required checks on the new code. It reads which checks are required from the branch's rules at that moment (the union of all applicable active rulesets and classic branch protection, preserving check context and required app identity). Only a successfully read, explicitly empty union passes at once; an unreadable or ambiguous source blocks merging as unknown. Code reviews, such as Copilot code review, are not checks and do not count. The screen shows the checks' progress. If they take longer than 30 minutes, the task moves to **approved, merge blocked** (engineering review, R6). -5. Immediately before merging, re-fetch both head and base; if either differs from the validated pair, restart attribution/rebase/checks instead of merging. Run the "already fixed" check again.

A final client-side fetch alone cannot close the race. If the repository/backend cannot provide that guarantee, automatic merging is blocked and the person must use GitHub's manual workflow; "Merge anyway" does not bypass this guard. Zero required checks still passes step 4, but does not waive this merge requirement. For a backend that provides the base guard, also pin the head with `gh pr merge --match-head-commit `.

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.

The authenticated `gh` account must be able to read the pull request, issue timeline, applicable rulesets, and classic branch protection, and to merge the PR. Codeboost unions required checks from both rule sources, requires strict server-enforced current-base checks, rechecks the base and head immediately before merging, and passes the reviewed head to `gh pr merge --match-head-commit`. Missing permissions and ambiguous rule responses block the merge. When the branch uses a merge queue, codeboost adds the exact reviewed head to the queue and treats the merge as done only when GitHub confirms it merged; a queued pull request is not merged, and removal or a changed head sends it back to review.

Those controls must be implemented before running code-writing agents. Question answering uses bounded supplied context in a separate temporary working directory, with command tools disabled. **Known limit:** Ask still runs the Claude Code or Codex CLI on your computer, not in the agent container, with your normal environment and your agent sign-in. A flaw in the CLI or a missed flag would therefore run with your account's access.

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.

After a restart, Ask stays off while any container, volume or network labelled `io.codeboost.allocation`, From 64ac02843118a86c282a6e791486e0906f97c4a6 Mon Sep 17 00:00:00 2001 From: mchwang Date: Sat, 26 Sep 2026 20:41:37 -0700 Subject: [PATCH 41/41] Read the Ask record and owner stamps without following links The leftover record and each folder's .owner stamp are now read through O_NOFOLLOW and accepted only as regular, single-link files within a size limit. A linked record makes the ledger unreadable (Ask fails closed and never acts on the record it points to); a linked stamp leaves the folder alone.
