Command: `python -m pytest -q tests --tb=short`. +- The first full Python run: **10,743 passed, 12 failed, 16 skipped**, plus + 340 passing subtests. Failures exposed a None-context plan permission check, + lightweight monitor contexts, and outdated lifecycle test doubles. These + were fixed; the affected regression group then passed **413 tests**. +- After the workflow startup fix, **197 workflow/runtime/server tests passed**. +- After the descendant-worktree fix, **38 worktree/supervisor tests passed**. +- PR CI additionally runs the full Python suite on Linux and Windows, + desktop checks on both platforms, web typecheck/tests/build, and the Harbor + adapter suite. The PR's checks are the authority for those platform results. +- Black and isort were applied to changed Python code. The four new runtime + modules pass targeted mypy. Full-project mypy reports **395 diagnostics** + versus **397 on the starting commit**, with **zero added diagnostics** after + normalizing line numbers. The environment lacks some third-party stubs; + this is a baseline comparison, not a claim that full-project mypy is green. +- The TUI typecheck and **65 agent-tree/task-output tests pass**. Its full + suite returned **1,896 passed, 8 failed, 4 skipped**. Seven failures reproduce + on an untouched archive of the starting commit (inline-diff formatting, + status-bar fields, indicator defaults, and height estimates). The eighth is + a cursor-layout timeout under the full concurrent run; all four cursor tests + pass when rerun alone, as on the baseline. No TUI source is changed by this patch. + +## Operational boundaries + +- **In-process collaboration:** remote-control workers, tmux/iTerm panes, and + UDS permission relay backends from the reference are not implemented here. + A filesystem mailbox is a persistence/delivery format, not a supported + cross-process team backend. Control records are checked against the live + runtime that issued them. +- **Same-session worker resumption:** completed local workers can resume after + HUD eviction because their executable continuation remains in the session. + A transcript alone does not recreate an executable worker after a process + restart. Workflow journals can replay successes when a new run is explicitly + launched with the matching script and prior run ID. +- **One team per workspace:** an existing `.clawcodex/team.json` is never + overwritten by another session. Normal shutdown removes an exited team. + A process crash may leave a stale roster; automatic crash recovery is not + provided. Confirm the prior process has stopped before manually removing it. +- **Task-board locking:** shared threads use a common RLock and atomic file + replacement. External processes editing the same JSON board do not join + that transaction. Direct owner reassignment remains allowed, matching the + reference; automatic pickup separately enforces owner/dependency eligibility. +- **Budget semantics:** the observed token budget prevents subsequent work + from starting after usage reaches the threshold. Already-running requests + can finish above it; this is not a provider-side hard spending cap. +- **Cancellation:** signals stop work at cooperative boundaries. A provider + blocked inside a synchronous call may finish that call before its thread + exits. Session cleanup has a bounded wait and retains a team still stopping. +- **Worktree retention:** changed or committed work is preserved. A clean + checkout still used by a background descendant is also preserved and its path + returned; it is not later deleted automatically. Isolation setup failure + never silently redirects edits to the parent checkout. diff --git a/src/agent/resume_agent.py b/src/agent/resume_agent.py index 1c07e6530..7328cc69a 100644 --- a/src/agent/resume_agent.py +++ b/src/agent/resume_agent.py @@ -1,74 +1,41 @@ -"""Auto-resume for terminal local_agent tasks — Chunk F / WI-7.4. - -Mirrors ``typescript/src/tools/AgentTool/resumeAgent.ts``.
