| Timestamp (UTC) | Task Slug | Task | Sandbox | Stage | Severity | Summary | Details |
|---|---|---|---|---|---|---|---|
| 2026-03-03 09:16:43 | Truncated cbox list names | M1-INFRA-018 | manager | dispatch | medium | Session names truncated in default list | Forced fallback to tmux for exact session identifiers. |
| 2026-03-03 09:16:43 | PR merge local delete warning | M1-INFRA-019 | manager | merge | low | gh merge reports branch-delete error with worktrees | Remote PR merged successfully; local cleanup warning looked like failure. |
| 2026-03-03 09:16:43 | Health check sequential delay | M1-INFRA-015 | sandbox | startup | medium | Sequential checks add avoidable latency | Four checks run serially with per-check timeout, inflating startup delay. |
| 2026-03-03 09:16:43 | Bootstrap command docs drift | M1-INFRA-016 | manager | review | medium | Docs not matching actual probe/bootstrap commands | Operator-facing docs lagged command changes in code. |
| 2026-03-03 09:16:43 | Bootstrap timeout hard-coded | M1-INFRA-017 | sandbox | startup | medium | Entrypoint timeout tuning unavailable | No env-level override for uv sync timeout behavior. |
| 2026-03-03 09:25:10 | Sandbox commit hook hang | M1-INFRA-020 | m1-infra-016-docs-sync | commit | high | Sandbox stalled during PATH-prefixed git commit | cbox send --interrupt did not unstick active bash tool call; required direct worktree takeover. |
| 2026-03-03T18:38:37Z | M1-INFRA-021 | tasks/workstreams/infra-tooling/tasks/master-plans-cli-ergonomics-and-command-wrappers.md | issue-m1-infra-021 | execute | high | Sandbox setup env copy failed and health checks missing python/pre-commit | During cbox new, .cursor/worktrees.json command cp /.env .env failed because ROOT_WORKTREE_PATH was unset; sandbox health checks then reported python/pre-commit not found, limiting automation reliability. |
| 2026-03-03T18:57:33Z | M1-INFRA-023 | tasks/workstreams/infra-tooling/tasks/cbox-task-execution-narrative-template-and-workflow-integration.md | issue-m1-infra-023 | execute | high | Sandbox startup had env copy, python/pre-commit, and git_auth failures | cbox new for issue-m1-infra-023 failed setup command cp /.env .env (unset ROOT_WORKTREE_PATH), then bootstrap checks reported python/pre-commit missing and git_auth failing because origin was not reachable inside sandbox. |
| 2026-03-03T19:44:00Z | M1-INFRA-024 | tasks/workstreams/infra-tooling/tasks/cbox-decoupled-task-workflow-command-surface.md | issue-m1-infra-024 | execute | high | Sandbox startup had env copy, python/pre-commit, and git_auth failures | cbox new for issue-m1-infra-024 failed setup command cp /.env .env (unset ROOT_WORKTREE_PATH), then bootstrap checks reported python/pre-commit missing and git_auth failing with github 500 during git ls-remote. |
| 2026-03-03T21:36:19Z | M1-INFRA-024 | tasks/workstreams/infra-tooling/tasks/cbox-decoupled-task-workflow-command-surface.md | issue-m1-infra-024 | review | medium | Sandbox parked at /pr-lite interactive prompt | issue-m1-infra-024 completed implementation summary but stopped at interactive /pr-lite prompt. Root causes observed: stale local pr-lite command in sandbox worktree and non-deterministic interactive handoff instead of deterministic /pr completion; earlier runs in sandbox also used python3 without venv and failed on ModuleNotFoundError: yaml. |
| 2026-03-03T21:36:59Z | M1-INFRA-006 | tasks/workstreams/infra-tooling/tasks/cbox-commit-review-gate.md | m1-infra-preflight-gates | review | high | Sandbox lacks container runtime for cbox review | m1-infra-preflight-gates output shows cbox review returning empty output and explicit docker/podman not found checks failing; flow halted at interactive blocker prompt, so task branch did not progress to PR. |
| 2026-03-03T21:49:46Z | M1-INFRA-025 | tasks/workstreams/infra-tooling/tasks/cbox-manager-default-parent-branch-policy.md | issue-m1-infra-025 | execute | high | New manager sandbox defaulted to main instead of manager branch | just cbox new issue-m1-infra-025 printed 'Using current branch as parent: main' despite manager work happening on codex/new-task-start; this confirms branch-context drift risk for newly created task files. |
| 2026-03-03T21:49:46Z | M1-INFRA-027 | tasks/workstreams/infra-tooling/tasks/cbox-manager-interactive-stall-detection-and-recovery.md | issue-m1-infra-027 | execute | high | New sandbox startup still missing python/pre-commit | issue-m1-infra-027 bootstrap health checks failed python and pre-commit immediately after setup-worktree commands; env still not reliably prepared for manager automation. |
| 2026-03-04T00:16:26Z | M1-INFRA-027 | tasks/workstreams/infra-tooling/tasks/cbox-manager-interactive-stall-detection-and-recovery.md | issue-m1-infra-027 | review | high | PR opened with cbox review skipped from sandbox blocker menu | Evidence: issue-m1-infra-027 output shows cbox review returned empty output due missing Docker/Podman, then interactive blocker menu offered 'Skip review, open PR'. Agent proceeded because 'do not pause' instruction was treated as implicit override. Resulted in PR #441 with unchecked review gate. Root cause: skip path existed and hard gate was not technically enforced in preflight. |
| 2026-03-04T00:16:36Z | M1-INFRA-027 | tasks/workstreams/infra-tooling/tasks/cbox-manager-interactive-stall-detection-and-recovery.md | issue-m1-infra-027 | review | high | RED FLAG: no-pause instruction incorrectly treated as review-skip approval | Evidence chain: 1) cbox review command returned empty output in sandbox due no Docker/Podman, 2) blocker menu exposed 'Skip review, open PR', 3) agent explicitly stated it would proceed because 'Do not pause at PR prompts' instruction existed, 4) PR #441 opened with unchecked review gate. Correct policy: no-pause only applies after gates pass; never implies skip approval. |
| 2026-03-04T00:18:31Z | M1-INFRA-027 | tasks/workstreams/infra-tooling/tasks/cbox-manager-interactive-stall-detection-and-recovery.md | issue-m1-infra-027 | review | high | Incorrect root-cause diagnosis: review path was tmux (CBOX_CONTAINER=1), not Docker-missing | Forensics in issue-m1-infra-027 shows CBOX_CONTAINER=1 before rerun; cbox review code in libs/cbox/cbox/cli.py routes to _run_review_in_tmux when CBOX_CONTAINER=1. Agent still concluded Docker/Podman missing after manual 'which docker' checks and proceeded with skip path. Root failure: gate enforcement + diagnosis logic allowed wrong inference and PR open despite required review. |
| 2026-03-04T03:32:44Z | GH-366 | tasks/workstreams/infra-tooling/tasks/add-cbox-test-command-for-running-visual-tests-locally-in-linux-container.md | issue-366 | review handoff | medium | Sandbox paused on host-only review handoff prompt | Output shows tests/lint/hooks all passed and branch pushed (6553422c), then paused at Run cbox review on host and create PR if approved. This is not /pr approval gating; it is a host-runtime handoff prompt requiring manager automation to continue. |
| 2026-03-04T03:32:44Z | GH-412 | tasks/workstreams/infra-tooling/tasks/smarter-cbox-cleanup-detect-squash-merged-prs-ignore-sandbox-artifacts-scan-all-worktrees.md | issue-412 | review handoff | medium | Sandbox paused at host review completion prompt | Output shows branch pushed (0dec5bb5) and explicit instruction Host review passed — proceed with /pr. Task is idle at interactive prompt, awaiting manager-issued next command. |
| 2026-03-04T03:32:44Z | M1-INFRA-027 | tasks/workstreams/infra-tooling/tasks/cbox-process-diagnose-and-hard-fail-silent-cbox-review-failures-in-sandboxes.md | task-diagnose-silent-review-failures | review loop | medium | Agent halted after REQUEST CHANGES review without auto-fix pass | Session produced review with 3 critical + 2 high findings and then stopped at Try "edit <filepath> to...". Blocker is missing deterministic "apply review feedback and continue" follow-on behavior after reviewer output. |
| 2026-03-04T03:32:44Z | M1-INFRA-028 | tasks/workstreams/infra-tooling/tasks/cbox-review-prompt-context-isolation-on-sandbox-restart.md | task-review-context-isolation | finalization | medium | Agent stopped at /pr command prompt |
Implementation/test work appears done, but session is parked at /pr interactive command instead of deterministic PR completion path. |
| 2026-03-04T03:32:44Z | M1-INFRA-029 | tasks/workstreams/infra-tooling/tasks/cbox-sandbox-session-liveness-drop-detection-and-recovery.md | task-session-liveness-recovery | execution gate | high | Agent blocked on internal plan approval menu | Session reached Claude has written up a plan and is ready to execute with options 1/2/3/4, then paused. This is a hard interactive gate caused by plan-approval mode in sandbox runtime. |
| 2026-03-04T03:32:44Z | M1-INFRA-030 | tasks/workstreams/infra-tooling/tasks/cbox-session-registry-stale-after-sandbox-kill.md | task-session-registry-stale-kill | execution | high | Agent idled at empty prompt after launching parallel sub-agents | Session shows Running 3 Agent agents... then returns to blank prompt with no deterministic continuation. Likely missed post-review continuation step after multi-agent output aggregation. |
| 2026-03-04T03:32:44Z | M1-INFRA-031 | tasks/workstreams/infra-tooling/tasks/cbox-sandbox-startup-timeout-diagnostics.md | task-startup-timeout-diagnostics | test | high | Session appears hung on long-running pytest command | Output shows background pytest launched and subsequent command in Waiting.../Fermenting... state for >20 minutes with no completion signal. Needs timeout/heartbeat guard and auto-recovery path. |
| 2026-03-04T03:34:26Z | M1-INFRA-029 | tasks/workstreams/infra-tooling/tasks/cbox-sandbox-session-liveness-drop-detection-and-recovery.md | task-session-liveness-recovery | execute | high | sandbox blocked on interactive plan-approval gate | Sandbox reached Claude menu 'plan is ready to execute' with options 1/2/3/4 and paused, preventing deterministic completion. Applying manager strategy: diagnose -> wipe sandbox+worktree -> restart fresh with strict auto-continue instructions. |
| 2026-03-04T03:37:02Z | M1-INFRA-029 | tasks/workstreams/infra-tooling/tasks/cbox-sandbox-session-liveness-drop-detection-and-recovery.md | task-session-liveness-recovery | execute | high | root cause identified: claude bypass gate still surfaced | After full wipe+restart, sandbox still paused at bypass-permissions prompt. Root cause: cbox launched Claude with --dangerously-skip-permissions but not explicit --permission-mode bypassPermissions. Fixed in libs/cbox/cbox/container.py and libs/cbox/cbox/cli.py; added regression tests in libs/cbox/test_container_runtime.py. |

Resetting sandbox/worktree per blocker loop. |
| 2026-03-04T08:43:27Z | cbox-sandbox-bootstrap-health-parity-for-python-and-pre-commit | tasks/workstreams/infra-tooling/tasks/cbox-sandbox-bootstrap-health-parity-for-python-and-pre-commit.md | task-cbox-sandbox-bootstrap-health-parity-for-python-and-pre-commit | execute | high | Repeated sandbox analysis stall without implementation | Second clean restart also stayed in read/explore loop (>1m+) with no git changes in task worktree. Escalating to manager-direct implementation for this task. |
| 2026-03-04T08:55:54Z | cbox-setup-worktree-root-worktree-path-fallback | tasks/workstreams/infra-tooling/tasks/cbox-setup-worktree-root-worktree-path-fallback.md | task-cbox-setup-worktree-root-worktree-path-fallback | execute | medium | Sandbox stalled in analysis with no code edits | After >1m of repeated read/search steps in cbox output, task worktree still had no modified files. Escalating to manager-direct implementation for deterministic progress. |
| 2026-03-04T09:25:50Z | cbox-session-registry-stale-after-sandbox-kill | tasks/workstreams/infra-tooling/tasks/cbox-session-registry-stale-after-sandbox-kill.md | task-cbox-session-registry-stale-after-sandbox-kill | review | high | In-sandbox cbox review no-runtime dead end | Sandbox reported /bin/bash: docker|podman not found and cbox review produced '(No output)' during /pr flow, blocking completion despite CBOX_CONTAINER context expectation. |
| 2026-03-04T10:05:12Z | cbox-session-registry-stale-after-sandbox-kill | tasks/workstreams/infra-tooling/tasks/cbox-session-registry-stale-after-sandbox-kill.md | task-cbox-session-registry-stale-after-sandbox-kill | execute | high | Sandbox branch reused with stale unmerged commit | cbox new reused existing sandbox/task-cbox-session-registry-stale-after-sandbox-kill branch containing old commit 77a1745e, causing task status/diff contamination and non-fresh execution context. |
| 2026-03-04T12:19:37Z | issue-412-smarter-cbox-cleanup | tasks/workstreams/infra-tooling/tasks/issue-412-smarter-cbox-cleanup.md | task-issue-412-smarter-cbox-cleanup | review | high | In-sandbox cbox review repeatedly hangs with no output | Sandbox reached cbox review and cbox review changes multiple times with blank output/stall; manager had to run host-side uv run --project libs/cbox cbox review changes and continue PR flow externally. |
| 2026-03-04T12:19:37Z | task-master-plans-cli-ergonomics-and-command-wrappers | tasks/workstreams/infra-tooling/tasks/master-plans-cli-ergonomics-and-command-wrappers.md | task-master-plans-cli-ergonomics-and-command-wrappers | startup | medium | Bootstrap still reports uv sync failed warning in sandbox |
Sandbox boot log continues to emit [cbox-bootstrap] warning: uv sync failed despite startup proceeding; indicates flaky/non-deterministic bootstrap dependency sync path that should be hardened/diagnosed. |
| 2026-03-13T20:50:39Z | refactor-tableinspector-inspection-pipeline-for-maintainability | tasks/workstreams/inspect-profiler/tasks/refactor-tableinspector-inspection-pipeline-for-maintainability.md | dataface-review-dataface1 | review | high | cbox review stalled without output artifact after restart | Direct restart via 'just cbox review changes' launched a fresh review bootstrap, but after 420s the process was still emitting heartbeats waiting for .cbox/reviews output. .cbox/reviews is empty, the expected tmux pane name does not exist, and the generic cbox-review session is idle at the Claude prompt rather than running the review. |
