此 __init__.py 文件同时导出了 ToolExecutor (来自 worker_tools.py) 和 SandboxToolExecutor (来自 sandbox_tool_executor.py)。根据设计文档，ToolExecutor 是一个操作本地文件系统的旧版实现，而 SandboxToolExecutor 是新的、在 VM 中操作的实现。为了避免混淆并引导其他开发者使用新的执行器，建议将旧的 ToolExecutor 重命名为 LegacyToolExecutor 或在其文档字符串中明确标记为已弃用。

在 detect_entry_point 函数中，通过 if __name__ == '__main__' 保护块来检测入口点的逻辑会遍历所有 Python 文件。这可能会意外地匹配到非预期的文件。虽然这是最后的备用策略，但为了提高准确性，建议优先扫描项目根目录下的 .py 文件，只有在根目录找不到时，才回退到扫描所有子目录。

实际上这个建议意义不大：
- 这已经是第 5 层 fallback，触发概率本身就低
- all_files 来自 list_files_recursive，文件顺序通常是广度优先/字母序，根目录文件本来就排在前面
- 真正的风险不在扫描顺序，而在于可能匹配到 setup.py、conftest.py 这类不应作为入口的文件 — 但这些通常不包含 if
name guard

在 _build_prompt 方法中，指令部分硬编码了文件组织结构的最佳实践（例如 src/, tests/）。这是一个很好的指导，但如果能将其提取到一个可配置的模板或共享的常量中，会让系统更具灵活性，以便未来支持遵循不同项目结构（如 app/ 目录）的 Node.js 项目。

loadRuntimeStateFromStorage 函数中包含了对旧版 boardSessionId 的迁移逻辑，这对于向后兼容性是很好的考虑。但是，这种迁移逻辑在未来可能会成为技术债务。建议添加注释，说明此逻辑用于从旧版状态迁移，并可以在未来的某个版本中移除。
// LEGACY MIGRATION: Handle old `boardSessionId` stored at the root of the runtime state.
// This can be removed in a future version after users have migrated.

19-19:⚠️ Potential issue | 🟡 MinorUnrelated change: revert runtime state update.
This timestamp update appears unrelated to the PR's objectives (Agent Board multi-agent system). The
last_seen_atfield tracks runtime state from the scholar subscription checker and should not be committed to version control.Recommended actions:
- Revert this change from the PR.
- Consider adding this file (or the
last_seen_at/last_seen_cached_papersfields) to.gitignoreto prevent future accidental commits of runtime state.- Alternatively, split configuration (schema, keywords, settings) from runtime state (timestamps, counts) into separate files—only version-control the configuration.

Narrow the exception handling and add test coverage for invalid email rejection in auth endpoints.
Line 13 catches all exceptions instead of specifically ImportError, which can mask unrelated import or runtime errors. Line 14 silently downgrades EmailStr to str, weakening validation. Additionally, while test_newsletter.py includes test_subscribe_invalid_email to verify invalid emails are rejected, test_auth_api.py lacks similar test coverage for the auth endpoints (RegisterRequest, LoginRequest, ForgotPasswordRequest) that also use EmailStr.

def test_register_invalid_email_rejected(isolated_db):
client = TestClient(isolated_db)
r = client.post("/api/auth/register", json={"email": "not-an-email", "password": "password123"})

Treat verification output as untrusted prompt input.
verify_summary comes from executing generated code inside the sandbox, so it is attacker-controlled input. Inserting it raw into the repair turn lets failing tests/logs steer the next model step and can also bloat the prompt with unbounded output.

226, The repair prompt currently injects untrusted sandbox output via
verify_summary directly into the parts list (see verify_summary and the parts
construction around "## Repair Attempt" / "## Verification Failure Summary");
change this to treat verify_summary as untrusted by truncating it to a safe max
length (e.g., 8000 chars), escaping or wrapping it in a fenced code block, and
replacing the raw insertion with the truncated/fenced version so the prompt
cannot be steered or ballooned by unbounded sandbox output.

@CJBshuosi, fair point — since paper_slug is an internal utility with a fixed default of max_length=40 and no external callers passing arbitrary small values, the guard would be dead code and unnecessary complexity. I'll drop that suggestion. Thanks for the clarification!

Add tests for the workspace_read_only parameter and default readonly behavior.
The workspace_read_only parameter directly changes runtime behavior—controlling whether the workspace is mounted as read-only (ro) or read-write (rw) in the Docker container (line 76). Currently, no tests exist for DockerExecutor. At minimum, add tests asserting the readonly default behavior and writable override.

- Around line 339-350: The fenced filesystem tree code block in the
agent-board-vs-manus-analysis.md proposal is missing a language tag (MD040);
update the fenced block that shows "/home/user/{paper_slug}/" so the opening
triple backticks specify a language (e.g., ```text) to satisfy markdownlint;
locate the fenced block with the directory tree and change the opening fence
accordingly.
In `@src/paperbot/infrastructure/swarm/codex_dispatcher.py`:
- Around line 201-203: The dispatch_with_sandbox_tools function currently
returns CodexResult without propagating the SandboxToolExecutor's
file_snapshots, causing replay data loss; update every return path inside
dispatch_with_sandbox_tools (both success and failure branches, including
exception/early-return paths between lines ~678-1026) to include
file_snapshots=dict(tool_executor.file_snapshots) when constructing CodexResult,
and ensure any existing returns that set error/diagnostics also pass this
file_snapshots value so snapshots tracked by SandboxToolExecutor are always
preserved.
In `@src/paperbot/infrastructure/swarm/persistent_sandbox.py`:
- Around line 37-77: existing executors that are present but unavailable are
being overwritten by self._executors[key] = created without cleaning them up,
leaking resources; modify the logic in the method that uses self._executors /
_create_executor (the block that checks existing.available() and then later sets
self._executors[key]) so that before assigning the new executor you acquire
self._lock, check if an existing executor is present and not available, call its
cleanup() if callable (and remove any stale lease from self._leases for that
user key), then replace the map entry and create the new lease via
self._new_lease; ensure cleanup and lease removal happen under the same lock to
avoid races and keep calls to _extract_sandbox_id/_new_lease unchanged.
In `@src/paperbot/infrastructure/swarm/worker_tools.py`:
- Around line 247-255: The code eagerly materializes the entire tree with
sorted(target.rglob("*")), which can load huge result sets before truncation;
update list_files and search_files to iterate the rglob generator lazily instead
of calling sorted(), stopping as soon as len(entries) >= MAX_LIST_ENTRIES; if
deterministic ordering is required, perform a directory-by-directory traversal
(e.g., os.walk/topdown=True) and sort each directory's immediate children before
yielding so you never build the full list in memory; update the loop that builds
entries (using p.relative_to(self.workspace).as_posix(), entries, and
MAX_LIST_ENTRIES) accordingly and apply the same change to the other occurrence
at the 310-327 range.
- Around line 337-338: The code currently sets done = bool(args.get("done",
False)), which treats the string "false" as True; update the parsing so done is
a real boolean by reading raw = args.get("done", False) and converting
explicitly: if raw is a bool keep it, if it's a string compare raw.lower()
against accepted true values ("true","1","yes","y") otherwise treat numeric
types nonzero as True; replace the existing assignment (the variable name done
in worker_tools.py where args is used) with this explicit conversion so "false"
and similar falsy strings result in False.
- Around line 393-443: The current _parse_pip_install_packages stops parsing at
shell operators (&&, ||, ;, |), letting a chained second "pip install" bypass
the allowlist; update _parse_pip_install_packages to treat chaining operators as
separators rather than terminators: when you encounter tokens like "&&", "||",
";", "|" skip the operator and continue scanning the remaining tokens, and if
you detect another pip install invocation pattern (e.g., "pip install" or
"python -m pip install") after the operator, parse and accumulate its package
names into the same packages list so the allowlist check (the parsed variable
used where parsed = _parse_pip_install_packages(command)) sees all packages from
chained installs and cannot be bypassed.
In `@tests/unit/repro/test_docker_executor.py`:
- Around line 7-8: Replace uses of unittest.mock's MagicMock and patch in tests
(references to MagicMock and patch in test_docker_executor.py) with explicit
local test doubles: create small _Fake* classes that implement the minimal
interface used by the tests (e.g., methods/attributes asserted in the tests) and
inject them via constructor parameters or use pytest's monkeypatch fixture
instead of patch. Update tests that currently call MagicMock to instantiate and
set state on the corresponding _Fake* instance and replace patch usages by
monkeypatching the target import to the fake object or by passing the fake into
the DockerExecutor/test helper constructors; assert against the fake's concrete
state instead of mock call assertions.
In `@web/src/lib/store/studio-store.ts`:
- Around line 821-838: In setContextPack, the early return when pack is null
leaves the selected paper's contextPackId stale; modify the branch in
setContextPack (function setContextPack) so that when pack is falsy and
state.selectedPaperId exists you update the selected paper(s) to set
contextPackId to null (and update updatedAt), call
savePapersToStorage(newPapers), and return { contextPack: pack, papers:
newPapers } instead of returning only { contextPack: pack } so persisted
metadata is cleared.
- Around line 403-426: Normalize the incoming id once at the start of
setBoardSessionId (e.g., const normalized = id && id.trim() ? id.trim() :
undefined) and use that normalized value everywhere: use normalized when
assigning boardSessionByPaper[selectedPaperId], when setting each
paper.boardSessionId in the papers map, when calling
savePapersToStorage(newPapers), and when returning boardSessionId in the final
state object; this keeps boardSessionId, boardSessionByPaper, and papers
consistent (refer to setBoardSessionId, boardSessionId, boardSessionByPaper,
papers, and savePapersToStorage).
- Around line 889-893: The current subscription created by
useStudioStore.subscribe (guarded by _runtimeSubscriptionAttached) calls
saveRuntimeStateToStorage(_snapshotRuntimeState(state)) on every mutation which
can cause main-thread jank; change this to a debounced/throttled persistence:
wrap the save call in a debounce or throttle (e.g., 250–1000ms) and use that
debounced function inside the subscription, ensuring you still call
_snapshotRuntimeState(state) when invoking the debounced saver; keep the
_runtimeSubscriptionAttached guard and ensure any pending debounced save is
flushed on page unload or before unmount if needed.
- Around line 281-283: parsed.pipelinePhase is currently cast to PipelinePhase
without validation, allowing invalid strings to leak into UI state; update the
assignment (the pipelinePhase field in studio-store where parsed and base are
used) to validate parsed.pipelinePhase against the allowed PipelinePhase values
(e.g., Object.values(PipelinePhase) or an isPipelinePhase(typeGuard) helper) and
only use the cast when it matches; otherwise fall back to base.pipelinePhase (or
a safe default). Ensure you add or reuse a type guard like isPipelinePhase and
replace the current typeof-then-cast logic with that validated check.
- Around line 243-299: Add regression tests that exercise the storage-layer
serialization/deserialization and migration logic: write tests that call
loadRuntimeStateFromStorage and saveRuntimeStateToStorage (mocking
window.localStorage), verifying (1) legacy boardSessionId at root migrates into
boardSessionByPaper for the selectedPaperId, (2) per-paper session restore
restores boardSessionByPaper entries, (3) session merge behavior when runtime
state and individual paper sessions conflict (exercising loadPapers which
consumes the persisted runtime), and (4) a full storage round-trip that
validates schema types (version, paperCache, agentTasks, pipelinePhase,
e2eState, sandboxFiles, timeEstimate) and falls back to _defaultRuntimeState on
invalid data; use realistic fixtures for parsed storage and assert resulting
PersistedRuntimeState values.

Propagate sandbox file_snapshots into CodexResult.
CodexResult now has file_snapshots, and SandboxToolExecutor tracks snapshots, but sandbox tool-loop returns do not populate that field. This drops replay-critical data on both success and failure paths.

Clean up replaced stale executors before overwriting the map entry.

Avoid full-tree materialization before truncation.

The code eagerly materializes the entire tree with sorted(target.rglob("*")),
which can load huge result sets before truncation; update list_files and
search_files to iterate the rglob generator lazily instead of calling sorted(),
stopping as soon as len(entries) >= MAX_LIST_ENTRIES; if deterministic ordering
is required, perform a directory-by-directory traversal (e.g.,
os.walk/topdown=True) and sort each directory's immediate children before
yielding so you never build the full list in memory; update the loop that builds
entries (using p.relative_to(self.workspace).as_posix(), entries, and
MAX_LIST_ENTRIES) accordingly and apply the same change to the other occurrence
at the 310-327 range.

Require a real boolean for done.
done = bool(args.get("done", False)) will treat "false" as True, which can incorrectly mark subtasks done.

The code currently sets done = bool(args.get("done", False)), which treats the
string "false" as True; update the parsing so done is a real boolean by reading
raw = args.get("done", False) and converting explicitly: if raw is a bool keep
it, if it's a string compare raw.lower() against accepted true values
("true","1","yes","y") otherwise treat numeric types nonzero as True; replace
the existing assignment (the variable name done in worker_tools.py where args is
used) with this explicit conversion so "false" and similar falsy strings result
in False.

Add regression tests for runtime persistence, migration, and per-paper restore flows.
The code introduces persistent schema behavior including legacy boardSessionId migration to per-paper sessions, per-paper cache restoration from storage, and session merging from multiple sources. The test file covers in-memory state transitions but has no tests for the storage layer (loadRuntimeStateFromStorage, saveRuntimeStateToStorage) or the deserialization and merge logic in loadPapers.
Per coding guidelines, behavior changes require tests for files matching {src,web/src}/**/*.{py,ts,tsx}. Add tests covering:
- Legacy
boardSessionIdmigration path - Per-paper session restore on load
- Session merge from papers and runtime state
- Storage round-trip with schema validation

parsed.pipelinePhase is currently cast to PipelinePhase without validation,
allowing invalid strings to leak into UI state; update the assignment (the
pipelinePhase field in studio-store where parsed and base are used) to validate
parsed.pipelinePhase against the allowed PipelinePhase values (e.g.,
Object.values(PipelinePhase) or an isPipelinePhase(typeGuard) helper) and only
use the cast when it matches; otherwise fall back to base.pipelinePhase (or a
safe default). Ensure you add or reuse a type guard like isPipelinePhase and
replace the current typeof-then-cast logic with that validated check.

Normalize boardSessionId consistently before writing state.
