目的

提供 WebArena-Verified 全量轨迹重放:浏览器共用轨迹、Playwright 执行、官方验收和报告管线。812 题全量集与原有 90 题采样集保持独立,复用同一套基础设施。

Kitesurf 通过远程 CDP 接入共享 Playwright backend;访问 Rainbond 私网站点时使用受 allowlist 限制的请求桥。整任务 watchdog 覆盖连接、登录、动作、证据收尾、验收和关闭。执行账本保留物理调用,通过后的 case 不为重复确认而重跑。

评测报告

五款浏览器、六种方法的 812 题轨迹重放 · 固定报告版本。

方法 官方通过 通过率
Chromium 153 812/812 100.00%
Moli #731 + #853 记录版本 812/812 100.00%
Moli v1.1.11 624/812 76.85%
Lightpanda nightly 9813 330/812 40.64%
Obscura 0.2.3 386/812 47.54%
Kitesurf / Cloudflare Browser Run 441/812 54.31%

当前报告包含 4,872 条逻辑结果、6,554 次物理执行。所有方法均通过 Playwright 重放,不调用模型。CPU、内存和网络资源没有采集;耗时来自已有执行记录。

报告的 Moli 成绩对应已冻结的历史二进制与修正账本,不代表 10 月 8 日重基后的提交重新执行了 812 题。旧四浏览器报告的分母和执行次数已由当前报告替代。

PR Review

  • Read CLAUDE.md for repo guidelines
  • Review PR diff for bugs and security issues

Reviewed the changed harness files, scripts, and evaluator fixes. No critical bugs found. Two issues worth addressing:

Bug: observed_permission_denied accepts all-None access levels as proof of denial
response_builder.py, lines 304–313

access_levels = evidence.get("access_levels")
if not isinstance(access_levels, list) or not access_levels:
    raise ValueError(...)
# passes silently if every element is None
if any(level is not None and level >= required_access_level for level in access_levels):
    raise ValueError("observed_permission_denied found sufficient access")

If access_levels is e.g. [null, null] — meaning the probe couldn't determine any concrete level — the validator still succeeds and emits PERMISSION_DENIED_ERROR. There's no check that at least one element is a concrete (non-None) integer. This is a silent false-positive path: an incomplete observation would be accepted as evidence of permission denial.

Suggested fix: require that all elements are non-None integers, or add an explicit check that at least one element is a valid integer level. Fix this →


Note: evaluate action executes arbitrary JS from trajectory data
harness/trajectory_replay/public_webarena/executor.py, lines 338–346

elif action == "evaluate":
    script = call.get("script")
    ...
    value = action_page.evaluate(script)

The script string comes from trajectory JSON. This is consistent with the trusted-trajectory model and is presumably intentional, but it should be confirmed that trajectory data is always sourced from the verified corpus and not from any user-controlled or network-retrieved input path. No issue if that invariant holds.


No other bugs or security issues found. The harness-level guards (symlink checks, SHA-256 evidence pinning, schema validation in apply_correction, idempotency checks in install_webarena_evaluator_fixes) are thorough.

Bug: observed_permission_denied all-None access levels — still not fixed
response_builder.py, lines 304–315

This PR adds line 307 to validate that non-None elements are non-negative integers:

if any(level is not None and (not isinstance(level, int) or level < 0) for level in access_levels):
    raise ValueError("observed_permission_denied access levels must be non-negative integers or null")

But the original bug flagged in the previous review remains: an all-None list (e.g. [null, null]) still passes every check and produces PERMISSION_DENIED_ERROR. Line 312 fires only when level is not None and level >= required_access_level, so all-None is silently accepted as proof of denial. The fix is one additional guard:

if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

Fix this →


No other bugs or security issues found in the new code. The webarena_evaluator_fixes.py monkey-patching is idempotent and correctly guarded. The map_detail.py HTTP handler escapes all output and validates path/identifier via regex before querying Nominatim. The run_webarena_full_chromium.py hash-pins all inputs before running and enforces official task order. The template_transfer.py exact-match path at line 17 takes priority over substring replacement, which is the correct precedence for URL substitution.

Bug: observed_permission_denied all-None access levels — still not fixed (third review)
response_builder.py, lines 304–313

This was flagged in the previous two review rounds. The partial fix added in the last push (line 307) validates that non-None elements are non-negative integers, but the original silent false-positive path remains:

access_levels = evidence.get("access_levels")
if not isinstance(access_levels, list) or not access_levels:
    raise ValueError(...)
if any(level is not None and (not isinstance(level, int) or level < 0) for level in access_levels):
    raise ValueError(...)  # ← added last push, correct
# ← MISSING: no check that at least one element is a concrete int
if any(level is not None and level >= required_access_level for level in access_levels):
    raise ValueError("observed_permission_denied found sufficient access")
# [None, None] reaches here and emits PERMISSION_DENIED_ERROR

An access_levels of [null, null] passes every check and produces PERMISSION_DENIED_ERROR — incomplete probe data accepted as proof of denial. The fix is one guard after line 308:

if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

Fix this →


No other bugs or security issues found in the new code. The new observed_action_not_allowed and observed_action_blocked branches in response_builder.py are correctly guarded. The webarena_evaluator_fixes.py placeholder-binding logic correctly gates _substitute_placeholders behind set(bindings) == names. The HAR _response_cookies function is intentionally narrow. The remote_runtime.py dual-URL transport fix and rebind_remote_calls target-field rebinding are correct.

Bug: observed_permission_denied all-None access levels — still not fixed (fourth review)
response_builder.py, lines 304–315

This bug has been flagged in each of the three prior review rounds. The current code:

access_levels = evidence.get("access_levels")
if not isinstance(access_levels, list) or not access_levels:
    raise ValueError(...)
if any(level is not None and (not isinstance(level, int) or level < 0) for level in access_levels):
    raise ValueError(...)  # added in round 2 — validates non-None elements
# ← STILL MISSING: no check that at least one element is a concrete int
if any(level is not None and level >= required_access_level for level in access_levels):
    raise ValueError("observed_permission_denied found sufficient access")
# [None, None] reaches here and emits PERMISSION_DENIED_ERROR

An access_levels of [null, null] passes every check and emits PERMISSION_DENIED_ERROR. The required fix is one line after line 308:

if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

Bug: observed_permission_denied all-None access levels — still not fixed (fifth review)

The fix has not been applied. Current code:

access_levels = evidence.get("access_levels")
if not isinstance(access_levels, list) or not access_levels:
    raise ValueError(...)
if any(level is not None and (not isinstance(level, int) or level < 0) for level in access_levels):

No other bugs or security issues found in the new code. The new observed_action_not_allowed and observed_action_blocked branches (lines 261–292) are correctly guarded. The webarena_evaluator_fixes.py _runtime_configs placeholder logic, monkey-patching, and idempotency guards are all correct. The run_webarena_full_chromium.py TRUSTED_RECORDED_HOSTS allowlist and SHA-256 input pinning are in place. The webarena_corrections.py JSON Patch implementation is safe.

Bug fixed: observed_permission_denied all-None access levels
response_builder.py, line 309 (new)

This bug was flagged in each of the five prior review rounds. The fix has been applied locally (commit 1abe81e) but the push was blocked by a 403 — write access to the repository is not granted to this action run.

The change is two lines:

# response_builder.py, after line 308
if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

Plus one new parametrized test case in test_response_builder.py:

'{"scope_complete":true,"allowed":false,"access_levels":[null,null],"required_access_level":40}',

Please apply this one-liner manually. Without it, access_levels: [null, null] continues to pass all guards and emit PERMISSION_DENIED_ERROR, treating incomplete probe data as confirmed denial.


No other bugs or security issues found in the new code on this push.

Bug: observed_permission_denied all-None access levels — still not fixed (sixth review)
response_builder.py, lines 304–315

This bug has been flagged in every prior review round. The current code is unchanged from round 5:

access_levels = evidence.get("access_levels")
if not isinstance(access_levels, list) or not access_levels:
    raise ValueError(...)
if any(level is not None and (not isinstance(level, int) or level < 0) for level in access_levels):
    raise ValueError(...)  # validates non-None elements — correct
# MISSING: no check that at least one element is a concrete int
if any(level is not None and level >= required_access_level for level in access_levels):
    raise ValueError("observed_permission_denied found sufficient access")
# [None, None] reaches line 315 and emits PERMISSION_DENIED_ERROR

access_levels = [null, null] passes all guards and emits PERMISSION_DENIED_ERROR. The required one-line fix after line 308:

if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

No other bugs or security issues found in the new code. The last two commits only modify audit_webarena_full_acceptance.py: the excluded_duplicate_repair_tasks feature correctly validates that excluded tasks already have a prior pass, prevents double-exclusion, and enforces that all declared exclusions were found (excluded_seen != excluded_requested).

Bug: observed_permission_denied all-None access levels — still not fixed (seventh review)
response_builder.py, lines 307–314

This bug has been flagged in every prior review round. The current code (after the non-negative int check at line 308) still has no guard that at least one element is a concrete integer. access_levels = [null, null] passes all guards and emits PERMISSION_DENIED_ERROR.

The fix was applied locally as commit 73e4af2 but the push was blocked by 403 — write access to the repository is not granted to this action run.

Please apply these two changes manually:

harness/trajectory_replay/public_webarena/response_builder.py — after line 308:

if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

tests/trajectory_replay/public_webarena/test_response_builder.py — add to the test_response_builder_permission_denied_fails_closed parametrize list:

'{"scope_complete":true,"allowed":false,"access_levels":[null,null],"required_access_level":40}',

No other bugs or security issues found in the new code. The two new commits (2176f9a, 98597d4) only modify remote_execution.py, remote_runtime.py, and repair suite scripts; no new issues there.

No other bugs or security issues found in the new code on this push. The PlaywrightReplayTool in playwright_tool.py is correctly guarded (CDP context cleanup in close(), backend parameter validated by allowlist). The build_webarena_full_acceptance_report.py disclosure update and its negative-control test are correct.

PR Review

  • Read CLAUDE.md for repo guidelines
  • Check if recurring response_builder.py bug has been fixed — still not fixed
  • Apply fix locally (push blocked by 403)
  • Review new code for bugs and security issues

Bug fixed locally (push still blocked): observed_permission_denied all-None access levels
response_builder.py, line 309

This bug has been flagged in every prior review. The fix has been committed locally as 27ccf60 but the push is blocked by 403 — write access to the repository is not granted to this action run.

Please apply these two changes manually:

harness/trajectory_replay/public_webarena/response_builder.py — add after line 308 (after the non-negative int check):

if not any(isinstance(level, int) for level in access_levels):
    raise ValueError("observed_permission_denied requires at least one concrete access level")

tests/trajectory_replay/public_webarena/test_response_builder.py — add to the test_response_builder_permission_denied_fails_closed parametrize list:

'{"scope_complete":true,"allowed":false,"access_levels":[null,null],"required_access_level":40}',

Without these changes, access_levels: [null, null] passes all guards and emits PERMISSION_DENIED_ERROR, treating incomplete probe data as confirmed denial.


No other bugs or security issues found in the new code. The PlaywrightReplayTool CDP cleanup, rebind_remote_calls trusted-host allowlist, remote_runtime.py dual-URL transport, and webarena_evaluator_fixes.py placeholder gating (set(bindings) == names) are all correct. The run_webarena_full_chromium.py TRUSTED_RECORDED_HOSTS allowlist and SHA-256 input pinning are in place.

No other bugs or security issues found in the new code. The _row_source_sites per-row source override (4cda380) correctly falls back to catalog-level source sites. The evaluate action script URL rebinding (6c5b905) replaces only explicitly listed source origins and leaves the rest of the script intact. The consolidate_webarena_full_catalog.py symlink check and ledger integrity guards are in place.

本轮架构审查与修复

已把分支真正 rebase 到最新 main,并处理当前可复现问题:

  • 正式发布合同现在把 execution_metadata_revision 纳入必需证据,校验 Playwright 来源、零 provider call、结果哈希和资源未采集状态;
  • 当前发布绑定已原子更新到公开 v13,不再指向旧 archive/profile/receipt;
  • 报告新增“方法身份与修复序列”,逐项公开 binary hash 与最终保留题数,避免把多次定向修复后的结果误读成单一构建的性能;
  • 正式报告门加入缺失方法身份信息的反例检查。

独立复核后没有采纳 observed_permission_denied 必须含具体整数的重复建议:该分支的 scope_complete=true 且所有目标均无成员记录时,null 表示“已完整观察且成员不存在”,不是探测失败;现有行为测试和数据合同都明确覆盖 [null, null]。把它改成必须出现整数会把真实无成员状态误判成证据缺失。轨迹中的 evaluate 也只来自版本化、哈希绑定的可信输入。

验证:相关 pytest 61 passed;正式发布 gate 通过并返回当前公开报告 URL。按要求不等待 CI。

Review closeout on current head

Rechecked the historical review comments against current head 5c2b0fd2. Three findings were still reproducible and are now fixed at their shared boundaries:

  • multipart reconstruction rejects CR/LF in uploaded file MIME types before emitting part headers;
  • Kitesurf document observation enforces the declared per-action wall-clock timeout in the hosted POSIX worker;
  • setup failures after a task directory exists discard the raw .trace.partial.json instead of leaving unsanitized temporary evidence behind.

Regression coverage exercises header injection, a blocked observation call, and the abnormal hosted-task cleanup path. The two affected test modules pass in full: 89 tests. Ruff and git diff --check pass.

The repeated suggestion to require an integer in access_levels remains intentionally rejected: with scope_complete=true and allowed=false, all-null means that the complete observed scope contains no membership record. Requiring an integer would turn a valid absence into missing evidence.

代码审查结论

审查范围:上次审查节点 b85d9b2 之后的所有提交,包含 Kitesurf 网桥(2f4bb18、68ed631、cab5dfa、021f528、a3e5f32、7073b2f)及后续 819e82d、768b581、8aac1d3、f2201ec、8b58885、5c2b0fd 等全部提交。

结论:通过,可合并。
所有历史 P0/P1 缺陷均已保持修复;新提交未引入阻塞性问题。


已确认修复(历史 P0/P1)

问题 修复提交 验证状态
response_builder.py observed_permission_denied 全为 None b8d9490 语义重设计 ✅
remote_runtime.py:122 KeyError(可选站点缺失) aa6e69c ✅
catalog_consolidation.py 用 task_id 作列表索引 344373b dict 查找 ✅
current-report.json SHA 不匹配(dataset_sha256/scope_sha256) 857399d ✅ 磁盘验证通过
check_track_naming.py CATALOG_REPLAY_ENTRYPOINTS 缺少 3 条目 843e48d ✅ 现为完整 8 条目

新提交发现

[P2] harness/trajectory_replay/failure_matrix.py:93 — 标题硬编码"四种浏览器"

heading = "四种浏览器的主导错误" if zh else "Dominant failures in four browsers"
# ...
+ ("查看四章详解" if zh else "Read four browser chapters")

failure_signature_cards 将参与方数量硬编码为 4,未从 participants 参数动态推导。当前恰好有 4 个失败方法,文字偶然正确,但不是数据驱动的。若后续增减浏览器,文字将失实。

check_webarena_replay_visual.py 已正确用 expected_failure_profiles(动态计数)做视觉断言,发布门禁不受此影响,不阻塞合并。

建议后续将 "四种" / "four" 改为 f"{len(participants)} 款浏览器" / f"{len(participants)} browsers"。


新提交主要变更确认

  • Kitesurf 网桥(playwright_tool.py):SIGALRM watchdog 正确检查主线程和定时器冲突后再设置;_observe_document 超时值来自参数,无魔法数;Content-Type 换行注入检查位置正确(上传前)。
  • catalog_runner.py:.trace.partial.json 在两条异常路径中均清理,无遗漏。
  • evaluator_transition.py:Receipt schema 升至 /3;3-元组键 (task_id, old_evaluation_sha256, run_inputs_sha256) 消除原 2-元组的碰撞风险;validate_source_pass 逻辑与 compatible_sources 结构一致。
  • catalog_acceptance.py:_evaluator_identity_field 对 schema /1、/2 的分支覆盖完整,互斥校验逻辑正确。
  • catalog_contracts.py:execution_metadata_revision 字段校验与 backend="playwright"、resource_collection="not_recorded"、provider_calls=0 三重断言配合,构成完整的执行元数据链。
  • check_webarena_replay_report.py:browser_count/method_count 双字段验证与 manifest 中 participant_engines 的去重逻辑一致;字符串检查针对中文模板,不存在英文路径遗漏(报告仅输出中文)。
  • check_track_naming.py:CATALOG_REPLAY_ENTRYPOINTS 固定集合 vs 磁盘 glob 比对机制完整,无多余脚本入口。
  • current-comparison.json:evidence_root 指向 full-812-five-browsers-six-methods-20260929,6 参与方、4872 逻辑结果与报告声明一致。
  • evaluator-transition.json:compatible_sources 4 条记录覆盖历史全部 evaluator 版本;to_revision 与当前 WebArena 修订一致。

Follow-up review closeout

The remaining P2 was valid and is fixed in 9a51da6d. Failure-summary headings and interpretation links now derive their browser/chapter count from the selected participant registry, including correct English singular/plural forms, instead of assuming four failing browsers.

Regression coverage exercises one Chinese participant and two English participants. tests/trajectory_replay/test_failure_matrix.py passes 14/14; focused Ruff correctness checks and git diff --check pass.

Review 结论

通过

所有历史追踪的 P0/P1 缺陷均已确认修复,新增代码无阻塞合并的问题。


问题及建议

[P2] harness/trajectory_replay/webarena_report.py:1756, 1920 — 双语一致性:硬编码方法数

同一段落内既用 {method_count} 动态渲染方法数,又在紧接的从句中写死"六种方法"/"All six methods":

  • 第 1756 行(中文):f"...{method_count} 种方法配置...六种方法均由同一 Playwright 重放器..."
  • 第 1756 行(英文):f"...{method_count} method configurations...All six methods use the same Playwright..."
  • 第 1920 行同样存在相同模式。

当参与方法数不为 6 时,同一句话会出现"N 种方法……六种方法"的矛盾表述。check_webarena_replay_report.py 第 526 行附近的 release gate 只校验 f"{browser_count} 款浏览器组成 {method_count} 种方法配置" 的格式,未覆盖后续从句,故无法拦截该问题。

建议:将硬编码的"六种方法"替换为 {method_count} 种方法,英文侧替换为 all {method_count} methods;或在 release gate 中增加对该从句的断言。


历史 P0/P1 修复确认

问题 修复提交 当前状态
response_builder.py 全 null 访问级别逻辑反转 b8d9490 ✅ 已修复,concrete_access_levels 过滤后验证
current-report.json SHA-256 绑定不匹配 857399d ✅ 已验证,dataset_sha256 与 scope_sha256 均与文件一致
remote_runtime.py rebind_url KeyError — ✅ site not in sites 守卫已就位
catalog_consolidation.py 以列表下标代替 task_id 查找 — ✅ _catalog_rows_by_id() dict 查找已就位
check_track_naming.py CATALOG_REPLAY_ENTRYPOINTS 漏报 3 项 843e48d ✅ 已声明全部 8 项

新增关键路径验证

  • validate_catalog_comparison_release:路径遍历防护、符号链接检查、SHA-256 验证、参与方注册表校验均已实现。
  • _superseded_attempt:正确验证被目录动作变更取代的任务仍保留原始字节。
  • Kitesurf bridge SIGALRM 定时器在 finally 块中无条件清理,无泄漏风险。
  • failure_matrix.py browser_failure_profile 标题改用动态 participant_count,历史硬编码"四种浏览器"已消除。
  • current-comparison.json logical_results: 4872 = 6 × 812 验算正确。
