Bug A: The agent sees an empty workspace because dockerHostPathPrefix translates the workspace mount source to a non-existent path. With sysroot-stage active, the Docker daemon can see all needed paths via: - Shared work volume (/home/runner/_work/) for workspace & RUNNER_TEMP - Sysroot named volume for system binaries - Kernel VFS for /dev, /sys Remove dockerHostPathPrefix from the AWF config — it's unnecessary and harmful when sysroot provides all system paths. Bug B: The agent artifact upload spans two path roots (/tmp/gh-aw/ and ${{ runner.temp }}/gh-aw/), causing upload-artifact to compute '/' as the common ancestor. This creates a nested directory layout that breaks downstream artifact downloads (detection job can't find agent_output.json). Fix by: 1. Rewriting all /tmp/gh-aw/ artifact paths to ${{ runner.temp }}/gh-aw/ 2. Adding a consolidation step that copies /tmp/gh-aw/ contents to the runner.temp location before upload Fixes: gh-aw#34896

...

Done. Found one lint failure (modernize: HasPrefix+TrimPrefix can be simplified to CutPrefix) in arc_dind_artifacts.go, fixed in commit fix(arc-dind): use strings.CutPrefix to satisfy modernize linter. No unresolved review threads. Local validation passes:

✅ Reviews — no unresolved review threads
✅ Checks (local) — make fmt, make lint (0 issues), make test-unit all pass
❓ Checks (CI) — stale after agent push; needs human re-trigger. Prior failures: fixed (lint was the root cause)
✅ Mergeable — branch is up to date with base, no conflicts

Hand-off: CI must be re-triggered by a maintainer (close/reopen PR, workflow_dispatch, or push) before merge.

...

Done. The branch had a merge conflict with origin/main in arc_dind_artifacts.go — both sides used strings.CutPrefix, so I resolved by taking the upstream variant (variable name after, rewritten++ increment for the first case). Local validation all passes: make fmt, make lint (0 issues), make test-unit.

✅ Reviews — no unresolved review threads
✅ Checks (local) — make fmt, make lint, make test-unit all pass
❓ Checks (CI) — stale after agent push; needs human re-trigger. Prior failures: fixed
✅ Mergeable — conflict resolved, branch updated from main

Hand-off: CI must be re-triggered by a maintainer before merge.

All clear. Branch is up to date with main, working tree clean, no unresolved review threads.

✅ Reviews — no unresolved review threads
✅ Checks (local) — make fmt, make lint (0 issues), make test-unit all pass
❓ Checks (CI) — stale after last agent push; needs human re-trigger
✅ Mergeable — no conflicts, branch is at origin/main tip

Hand-off: CI must be re-triggered by a maintainer before merge. Still needed: human approval.

✅ Reviews — no unresolved review threads
✅ Checks (local) — make fmt, make lint (0 issues), make test-unit all pass
❓ Checks (CI) — Smoke CI shows action_required (pending maintainer approval for PR workflow runs, not actual test failures); stale after agent push. Prior failures: none found at log level
✅ Mergeable — branch is up to date with main (merged at 098f5a6), no conflicts

Actions taken: no new changes needed — branch was already clean.
Hand-off: CI must be re-triggered by a maintainer (close/reopen PR, workflow_dispatch, or push) before merge.
Still needed: human approval and maintainer CI approval for workflow runs.

Fixed a pre-existing test failure introduced by main. TestPRSousChefWorkflowAddCommentTargetContract was still asserting the old "Process at most 5 PRs per run." text, but pr-sous-chef.md was updated in #43492 to "Process all eligible PRs per run." — updated the test to match in fix(test): update pr-sous-chef contract test to match current workflow.

✅ Reviews — no unresolved review threads (0 threads)
✅ Checks (local) — make fmt (clean), make lint (0 issues), make test-unit (all pass)
❓ Checks (CI) — stale after agent push; needs human re-trigger. Prior runs on HEAD c6fa00f all concluded success
✅ Mergeable — branch is up to date with main, no conflicts

Still needed: human approval.

Branch updated from main and pre-existing test failure fixed:

Merged conflict in pr_sous_chef_workflow_contract_test.go (same string both sides, took upstream message wording)
Fixed pr-sous-chef.md: updated "Process at most 5 PRs per run." → "Process all eligible PRs per run." to align the source with the compiled .lock.yml (changed in pr-sous-chef: process all PRs, treat marker-only comments as informational #43492) and the contract test (updated in b8641b2baf on main). Recompiled pr-sous-chef.lock.yml.
