+Public report CLIs fall back to English. `BROWSER_EVAL_REPORT_LANGUAGE` changes the environment default; an explicit `--language` wins, and a rebuild preserves the saved primary language. For an agent-driven build, select the language from the current conversation. English builds retain the matching Chinese edition; a Chinese selection does not generate an English translation unless explicitly requested. Keep measured material in its source language. Historical Chinese-only renderers must disclose that limit and reject unsupported requests. Bind generated languages and the selected entry in report metadata. English navigation opens a not-generated notice when absent; never publish stale English pages. Validate each generated edition and retain route, value and evidence-link parity checks when both exist.
 
 1. Establish the decision being supported, the measured unit, cohort, versions, execution location, freshness policy, and intended deliverable. Inspect the actual dataset, runner, outputs, scorer, prior review evidence, and current report. Do not infer them from screenshots or prose.
 2. Freeze a machine-readable evaluation contract before expensive calls. It must identify the exact cases and methods, run count, timeout, concurrency policy, input and output contract, scoring provenance, reference state, and publication target when one exists. Existing compiled reference answers are frozen by default. Source metadata, capture dates, and absent newer acceptance-contract fields do not imply a live-reference task. Only tasks explicitly declaring `source_verification.reference_mode: live_exact` require live checks. For those tasks, fail closed: verify and freeze references immediately before calls, verify the same declared scope afterward, and certify the cohort only when both checks pass. An unchanged compiled acceptance-contract dataset is already the benchmark input: freeze its task and rule bytes for execution, without requiring historical source-qualification raw files or re-auditing cohort admission. Qualify sources when adding tasks or changing references/acceptance rules; do not turn an ordinary version rerun into dataset reconstruction. Partial or uncertified cohorts remain diagnostic evidence and cannot enter a release.
 3. Let each method use its strongest documented route to produce the required output. Equalize the task, inputs, output contract, call budget, and scoring. Do not require identical internals. For fixed-native cohorts, declare the input media type independently of URL patterns and expected answers, freeze the class-level route and transport parameters before calls, and verify the retained request receipts at aggregation and release. Record material asymmetries such as local versus remote execution, cold versus warm start, bundled conversion, network transit, account tier, and billable time.
 4. Preserve evidence as an append-only chain by default: task definition, reference, provider call, raw artifact, normalized artifact, score, review, revision, and release. If the user explicitly requests deletion of superseded history, validate the chain first and use the existing owner's current-only authority described in [audit and revision](references/audit-and-revision.md); remove obsolete full snapshots rather than storing reverse patches. Keep current provider outputs, call identities, real scoring sources and necessary review evidence immutable. Routine refresh and publication reuse current inputs without redundant historical snapshots. A presentation or scoring change must not masquerade as a new provider result. Declare the native answer fields and validate their structural projection before accepting a scored artifact. Adapters must not remove returned candidates by URL meaning or consult expected answers when selecting candidate fields. Apply privacy redaction only to separately identified public views after scoring, preserving the private originals and distinguishing original, scored and public-view hashes.
-5. Separate retrieval success, task acceptance, content quality, latency, cost, and freshness. A missing or partial reference makes the affected metric unavailable or scoped; it does not prove success or failure. Do not derive binary acceptance from an unrelated aggregate similarity score.
+5. Separate retrieval success, task acceptance, content quality, latency, cost, and freshness. Treat missing telemetry as unavailable. A request that received no first byte contributes to total latency, but not to first-byte or body-transfer stage means; show each stage’s observed population. A missing or partial reference makes the affected metric unavailable or scoped; it does not prove success or failure. Do not derive binary acceptance from an unrelated aggregate similarity score.
 6. For heterogeneous same-window latency evidence, preserve the full predeclared task-by-method matrix. Show all-call latency on that common denominator separately from successful-call latency on each method's conditional subset. Treat the all-method shared-pass intersection as a diagnostic, never as a post-outcome selector or ranking sample.
 7. At aggregate and publication boundaries, copy only explicit hash-bound evidence and public audit files. Reject symlinks and exclude worker trees, host paths, credentials, and internal run logs. Verify primary, auxiliary, delivered-file, and retained retry artifacts before release.
    When a saved-input handoff needs host-metadata redaction, use the shared publication privacy owner. Preserve private originals and distinguish original from public file hashes; rebind dependent metadata references and disclose auxiliary debug-log projections. Never rewrite original scored answers, references or response payloads as a privacy repair. When a scored answer or native envelope itself contains private values, create a separately identified post-score public view through the shared privacy owner, verify its native-field projection and unchanged task verdict, and disclose that omitted original bytes cannot be reconstructed from the public copy. A public frozen presentation must explicitly bind its complete view inventory, verify displayed bytes against those views, keep acquisition gates strict, and distinguish preserved original diagnostics from what redacted text can reproduce. Verify unchanged verdicts, timings and review decisions, and rebuild from the public inputs.

 12. Present one authoritative logical result per method and task. The frozen protocol chooses the score-bearing execution; a renderer must never silently replace that rule.

 Browser Eval owns execution adapters, evidence handling and report tooling. `lexmount/lexbench-webfetch` owns Web Fetch task populations, task models, deterministic acceptance scoring, compilation and frozen definition files. Import its pinned package directly; do not duplicate or re-export retired evaluator modules here.

WebMainBench, WCXB and WebArena retain their own upstream task authorities.

Preserve original-language source quotations and hash-bound acceptance/evidence artifacts. Report-generation languages follow the track contracts below.

Predeclare the complete task scope, alternate call order within each task, run serially on a quiet host, bind both binary hashes and all physical calls, and select a round before seeing results. If an earlier timing is corrected, retain it privately, supersede every affected logical timing, and make the report table and detail agree. Release checks must reject an absent or partial timing receipt.
 - New or substantially rewritten report renderers must wire semantic presentation checks into their release gate, with negative controls for missing/wrong highlights, duplicate summaries, broken evidence targets and missing failure logs. Use `harness/reporting/presentation.py` or equivalent track-specific adapters. A written instruction or a route-count check is not proof that the UI requirement is enforced.

 - A reference, scoring or acceptance correction must fix the shared cause, not patch stored verdicts or one provider. Add paired executable controls to `evaluation/scoring-regressions.json` where both error directions are plausible, run them through the public `score_attempt` and task predicate, and bind the root cause plus regression IDs in every new reference/scoring revision receipt. A revision without this provenance fails before evidence is changed.
 - A heterogeneous same-window latency cohort keeps every predeclared method-task call. Report the common-denominator all-call distribution separately from each method's conditional successful-call distribution; an all-method common-pass intersection is diagnostic only and must never drive post-outcome task selection or a ranking.
 - Evaluation credentials come only from the repository `.env`. Artifact Site publishing is the sole user-scoped exception: read explicit `ARTIFACT_SITE_TOKEN`, then `~/.config/artifact-site/tokens/<target-host>`; the previous `ARTIFACT_HUB_TOKEN` and `~/.config/artifact-hub/` locations are read-only migration fallbacks. Never load `.env` for publishing. Save new authorizations per target host without overwriting another deployment's token. Keep `.env.example` current and publish only account requirements, official acquisition links and variable names.
-- Public report CLIs default to English where the owning renderer supports it; expose `--language en|zh` and preserve the saved primary language on rebuild. English builds retain the matching Chinese edition. Chinese-only historical renderers must state their limitation and reject an English request rather than relabel untranslated pages. Never infer language from host locale or translate measured evidence. Record generated editions and the selected entry in report metadata. When English is absent, its navigation opens a not-generated notice with a return link; never ship stale English pages. Check the generated languages and notice, and require matching route inventories, section order, tables, values, filters and evidence links when both editions exist.
+- Public report CLIs fall back to English. `BROWSER_EVAL_REPORT_LANGUAGE` changes the environment default; an explicit `--language` wins, and an existing report preserves its saved primary language.

English builds retain the matching Chinese edition; a Chinese selection generates no English translation unless explicitly requested. Keep measured material in its source language.

Task-specific requirements live in case configuration, not provider- or track-specific scoring branches. Binary acceptance and text diagnostics remain separate; missing reference coverage is unavailable, not zero or perfect.
 - Dynamic-content reference capture follows `harness/web_fetch/README.md`: retain paired initial HTTP bytes and independently rendered visible text, bound completion and the full declared scope. Distinguish embedded state from follow-up fetching; never require JavaScript as the only valid route.
 - Popular-site stable text must be independently observed and task-relevant. Do not freeze volatile ranks, prices, member counts or current list membership. Title diagnostics join returned entities to independent names by detail URL and never substitute for body quality, recall, freshness or task acceptance.

 - Browser Trajectory Replay canonical inputs must not contain run-local snapshot refs. Compile each ref to a hash-bound stable selector while preserving the original ref action semantics; do not silently replace a DOM ref click/fill/select with BrowserTool's Playwright selector fallback because that adds different viewport, overlay and navigation-wait behavior.
 - Browser Trajectory Replay reports keep the dataset separate from measured verdicts. Every task needs a contract-and-qualified-trajectory page; every result needs a same-task all-browser comparison, a reader-facing failure locator, the exact failed-action or evaluator error, reviewed cause, complete expandable tool responses, and on-demand public evidence. The result inventory stays compact, fixed-height, filterable and linked to a diagnosis dialog. The same-task explorer uses a registry-driven baseline, multi-select comparison browsers and explicit outcome relations; group pass/fail links instead of adding one result column per future browser. Keep Chinese and English task/result routes aligned.
 - A BrowserTool call that returns success does not prove its intended site mutation occurred. When the official evaluator rejects a completed trajectory for an absent required network event, locate the last plausible trigger action and publish the exact missing-event assertion, but do not mark that action as failed or change the official verdict. Repair asynchronous or position-dependent trajectory inputs only through new qualification evidence and a frozen full-scope comparison rerun.

Dataset routes contain only frozen task definitions and acceptance contracts; result routes own verdicts, timings and trajectories. Keep one filterable result inventory instead of adding duplicate success/failure tables.
 - Keep automatic evaluator failure location separate from reviewed root cause. A root-cause subtype and reason must come from a per-browser, per-task review bound to the current attempts hash; render both fields blank while that result is unverified, and require complete verified coverage before a formal release when the current profile enables the gate.
 - Generate browser rows and comparisons from the participant registry. The same-task explorer uses one baseline browser, multi-select comparison browsers and explicit outcome relations, with browser labels linking to full results; never add one fixed table column per future browser. List Agent, model, prompt/tool contract, resources, environment and evaluator as shared controls.

+Browser Eval is an extensible evaluation harness for browsers and web agents. It combines task contracts, adapters, saved evidence and scoring to produce inspectable reports.
 
-Browser Eval connects benchmark tasks to browser and service adapters, executes declared comparisons, calls the benchmark scorer on saved outputs and builds inspectable reports. It supports Web Fetch, Browser Trajectory Replay and Browser Use. Task populations and acceptance requirements come from the selected benchmark.
+## Evaluation tracks
 
-[LexBench Web Fetch](https://github.com/lexmount/lexbench-webfetch) owns the self-authored Web Fetch task suites. WebMainBench, WCXB and WebArena supply other benchmark inputs. Browser Eval provides the execution and reporting machinery; each benchmark retains its own scope, versions and attribution. See [repository boundaries and integration](docs/benchmarks.md).
+The following workflows have runnable guides; see [contributing](CONTRIBUTING.md) for the adapter and task-contract model.
 
-You get an HTML report with comparison tables, task details, responses and logs. Read it locally or publish it through [Artifact Site](https://github.com/lexmount/artifact-site) so others can explore the results online.

 ## Quickstart
 
-Clone the repository, open a terminal in its root, and install [uv](https://docs.astral.sh/uv/getting-started/installation/). The base CLI supports Python 3.11–3.14; repository development defaults to 3.11.
+Install [uv](https://docs.astral.sh/uv/getting-started/installation/), then run the offline example:
 
-```bash
+```sh
+git clone https://github.com/lexmount/browser-eval.git
+cd browser-eval
 uv sync --frozen
 uv run --frozen browser-harness-eval validate
 uv run --frozen browser-harness-eval run --delay 0
 ```
 
-Open the report path printed in the terminal. This offline example needs no browser, Docker or API key. It contains one expected pass and one expected failure so you can see both kinds of result. Installation needs network access.
-
-Next, [run HTTP, Moli or Chromium against a local article](examples/web_fetch/README.md). That guide covers browser installation, selecting several methods and choosing your own tasks. Remote services and Agent runs need their own accounts; their calls may incur charges.
-
-<details>
-<summary>Choose another Python version or install an optional adapter</summary>
-
-To use Python 3.12, add `--python 3.12` to both `uv sync --frozen` and subsequent `uv run --frozen` commands. Optional adapters and historical experiments have additional version constraints; the full development environment uses 3.11.
+Open the report path printed in the terminal. The example has one expected pass and one expected failure; it needs no browser, Docker or API key. Python 3.11–3.14 is supported; development uses 3.11.
 
-| Extra | Used for |
-| --- | --- |
-| `headless-eval` | Chromium, PDF parsing and container measurements |
-| `webmainbench-eval` | WebMainBench scoring |
-| `browser-use-eval` | WebArena and Agent execution; requires Git for the pinned evaluator |
-| `oss-eval` | Open-source extraction libraries |
+Next, [try HTTP, Moli or Chromium on a local article](examples/web_fetch/README.md). Optional adapters, service credentials and live evaluation commands are covered in the track guides above.
 
-Install an extra with `uv sync --frozen --extra NAME`. Browser binaries, Docker, site datasets and accounts are installed separately. See [dependencies](docs/dependencies.md).
+## Reports
 
-</details>
+Reports include comparisons, task results, full responses and failure evidence. Runs are saved under `~/.browser-eval/runs/`; use `--output /absolute/path/new-run` to choose another directory.
 
-## Read and share a report
+Rebuild from saved evidence without repeating calls:
 
-Reports retain the selected benchmark edition and exact dataset/scorer hashes.
-Package upgrades leave historical results unchanged. See
-[benchmark editions](docs/benchmarks.md#benchmark-editions) for patch, minor and
-major comparison rules.
-
-| Output | What you will find |
-| --- | --- |
-| `report/en/index.html` | English comparisons, task results and evidence links |
-| `report/index.html` | Report entry; opens the selected language |
-| `results.jsonl`, `summary.json` | Scores and aggregates for scripts or further analysis |
-| `manifest.json`, `dataset.json` | Methods, versions, settings and tasks used |
-| `artifacts/` | Saved responses and other evidence |
-
-Runs go to `~/.browser-eval/runs/` by default. Set `BROWSER_EVAL_DATA_HOME` to change the root, or `--output /absolute/path/new-run` for one run. Each run needs a new directory.
-
-Rebuild a report from saved evidence without repeating browser or API calls:
-
-```bash
+```sh
 uv run --frozen browser-harness-eval report /absolute/path/to/run
 ```
 
-The Web Fetch CLI opens English by default, with a switchable Chinese edition. Choose Chinese when starting a run, or change the language of a saved report:
-
-```bash
-uv run --frozen browser-harness-eval run --delay 0 --language zh
-uv run --frozen browser-harness-eval report /absolute/path/to/run --language en
-```
-
-Rebuilding without `--language` keeps the previous choice. Language changes do not repeat calls or change scores; task wording, responses and logs retain their original language. English (`en`) and Chinese (`zh`) are supported; other language codes are rejected. See [report language support](docs/report-hosting.md#report-languages) for the standalone builders and historical reports.
-
-Frozen local snapshots use their own external `presentation-binding.json`; keep report-specific profiles and publication targets with their saved evidence, outside Git. Follow the [frozen local report workflow](harness/web_fetch/README.md#frozen-local-report-inputs) to check or rebuild them without changing saved scores.
-
-To publish online:
+English is the default; add `--language zh` when running or rebuilding for Chinese. A rebuild without that option keeps the saved language.
 
-1. Sign in or create an account on the [China site](https://artifact-site.lexmount.cn/) or [global site](https://yours.lexmount.com/artifact-site).
-2. Publish the run's `report/` directory using the [CLI or MCP guide](docs/report-hosting.md).
-3. Choose who can open the report in its sharing settings.
+Each new report records its Browser Eval build and selected benchmark edition, with exact code and input hashes. See [versioning](docs/benchmarks.md#benchmark-editions) for comparison rules and [reference inputs](docs/reference-inputs.md) for historical data.
 
-[Artifact Site](https://github.com/lexmount/artifact-site) is open source and supports self-hosting, report versions and access controls. Local reports need no hosting account and never upload automatically.
-
-Example runs are diagnostic. For a formal benchmark release, follow the selected track's certification and release checks; uploading a report does not certify it.

 ## Cite Browser Eval
 
-If you use the harness in published work, cite this repository and record the tag or commit used. Cite LexBench Web Fetch or other benchmark owners separately for their task definitions and methodology. GitHub's citation menu reads [CITATION.cff](CITATION.cff). For the initial release:
+Use this citation or [CITATION.cff](CITATION.cff), and record the commit used.
 
 ```bibtex
 @software{browser_eval_2026,
   author = {{Browser Eval contributors}},
   title = {Browser Eval},
   year = {2026},
-  version = {0.1.0},
+  version = {0.2.0},
   url = {https://github.com/lexmount/browser-eval}
 }
 ```
-
-Cite upstream benchmarks and evaluators separately when using their data or methods; this repository citation does not replace their attribution requirements.
-
-Update the pinned LexBench evaluator with `make bump-lexbench REV=<full merged commit>`. The command verifies upstream main ancestry, regenerates the lock and definition hashes, and prints changed bindings. Historical report certificates retain their original evaluator identities.
-
-Web Fetch method descriptions, interfaces, account requirements, capability sources, and their English/Chinese text share one registry: `harness/web_fetch/data/report-methods.json`. Register a new product there; executable versions and run parameters come from saved evidence. See [method metadata](harness/web_fetch/README.md#report-method-metadata) for the distinction between registered examples and measured calls.

+Browser Eval 是面向浏览器和 Web Agent 的可扩展评测框架，将任务规则、适配器、保存的证据和评分结果汇集为可查阅的报告。
 
-Browser Eval 把 benchmark 任务接到浏览器或服务适配器上，执行预先声明的比较，调用 benchmark 评分器检查保存的输出，并生成可查看证据的报告。它支持 Web Fetch、轨迹重放和 Browser Use；任务范围和验收要求由所选 benchmark 决定。
+## 评测流程
 
-自建的 Web Fetch 任务集由 [LexBench Web Fetch](https://github.com/lexmount/lexbench-webfetch) 维护。WebMainBench、WCXB 和 WebArena 提供其他评测输入。Browser Eval 负责执行与报告，各 benchmark 分别维护范围、版本和来源说明。详见[仓库分工与接入](benchmarks.md)。
+以下流程均有可运行的指南，适配器和任务规则见[贡献指南](../CONTRIBUTING.md)。
 
-运行后得到 HTML 报告，里面有比较表、任务详情、响应和日志。可以在本地查看，也可以通过 [Artifact Site](https://github.com/lexmount/artifact-site) 发布，让其他人在线查看结果。

 ## 快速开始
 
-克隆仓库，在根目录打开终端，安装 [uv](https://docs.astral.sh/uv/getting-started/installation/)。基础 CLI 支持 Python 3.11–3.14，仓库开发默认使用 3.11。
+安装 [uv](https://docs.astral.sh/uv/getting-started/installation/)，运行离线示例：
 
-```bash
+```sh
+git clone https://github.com/lexmount/browser-eval.git
+cd browser-eval
 uv sync --frozen
 uv run --frozen browser-harness-eval validate
 uv run --frozen browser-harness-eval run --delay 0
 ```
 
-打开终端打印的报告路径。这个离线示例无需浏览器、Docker 或 API Key，预设一个通过结果和一个失败结果，方便查看两种情况。安装依赖时需要联网。
-
-接下来，可以[用 HTTP、Moli 或 Chromium 抓取本地文章](../examples/web_fetch/README.md)。说明中包含浏览器安装、多方法比较和自选任务。远程服务和 Agent 运行需要相应账户，调用可能产生费用。
-
-<details>
-<summary>选择其他 Python 版本或安装可选适配器</summary>
-
-使用 Python 3.12 时，在 `uv sync --frozen` 和后续 `uv run --frozen` 命令中都加上 `--python 3.12`。可选适配器和历史实验另有版本要求，完整开发环境使用 3.11。
+打开终端打印的报告路径。示例包含一个预期通过和一个预期失败，无需浏览器、Docker 或 API 密钥。支持 Python 3.11–3.14，仓库开发使用 3.11。
 
-| 额外依赖 | 用途 |
-| --- | --- |
-| `headless-eval` | Chromium、PDF 解析和容器测量 |
-| `webmainbench-eval` | WebMainBench 评分 |
-| `browser-use-eval` | WebArena 和 Agent；安装固定提交的评估器需要 Git |
-| `oss-eval` | 开源提取库 |
+接下来可以[用 HTTP、Moli 或 Chromium 读取本地文章](../examples/web_fetch/README.md)。可选适配器、服务凭据和在线评测命令见上面的各流程指南。
 
-用 `uv sync --frozen --extra NAME` 安装。浏览器、Docker、网站数据和账户分别准备，见[依赖说明](../docs/dependencies.md)。
+## 报告
 
-</details>
+报告包含结果对比、逐题结果、完整响应和失败证据。运行结果默认保存在 `~/.browser-eval/runs/`，也可用 `--output /absolute/path/new-run` 指定新目录。
 
-## 查看与分享报告
+从保存的证据重建报告，无需重新调用浏览器或服务：
 
-报告固定绑定所选评测版本，以及题目和评分源码的精确哈希。升级软件包不会改变历史结果。
-补丁版可以直接比较；评分修正的小版本要统一重评；题目或任务要求改变的大版本分别展示。
-具体规则见[评测版本](benchmarks.md#benchmark-editions)。

-| 输出 | 内容 |
-| --- | --- |
-| `report/en/index.html` | 英文比较、任务结果和证据入口 |
-| `report/index.html` | 报告入口，打开所选语言 |
-| `results.jsonl`、`summary.json` | 供程序分析的评分和汇总 |
-| `manifest.json`、`dataset.json` | 使用的方法、版本、设置和任务 |
-| `artifacts/` | 保存的响应及其他证据 |
-
-默认保存在 `~/.browser-eval/runs/`。用 `BROWSER_EVAL_DATA_HOME` 改数据根目录，或用 `--output /absolute/path/new-run` 指定本次输出。每次运行需要一个新目录。
-
-从保存的证据重建报告，无需再次调用浏览器或 API：
-
-```bash
+```sh
 uv run --frozen browser-harness-eval report /absolute/path/to/run
 ```
 
-Web Fetch 命令默认打开英文报告，并保留可切换的中文版。开始评测时可以选中文，也可以更改已有报告的语言：
-
-```bash
-uv run --frozen browser-harness-eval run --delay 0 --language zh
-uv run --frozen browser-harness-eval report /absolute/path/to/run --language en
-```
-
-重建时不传 `--language`，会沿用上次的选择。切换语言不重新调用浏览器或服务，也不改变评分；任务原文、响应和日志保留原来的语言。目前支持英文（`en`）和中文（`zh`），其他语言代码会报错。独立构建器和历史报告的支持范围见[报告语言说明](report-hosting.md#report-languages)。
-
-冻结的本地报告使用随证据保存的 `presentation-binding.json`。报告专用配置和发布目标保存在 Git 之外，与该报告的证据放在一起。按照[冻结本地报告流程](../harness/web_fetch/README.md#frozen-local-report-inputs)检查或重建，不改变保存的评分。
-
-在线发布：
+默认生成英文；运行或重建时加 `--language zh` 可选中文。重建时不传该选项，会沿用已保存的语言。
 
-1. 在[中国站](https://artifact-site.lexmount.cn/)或[全球站](https://yours.lexmount.com/artifact-site)登录或创建账户。
-2. 按 [CLI 或 MCP 说明](../docs/report-hosting.md)发布本次运行的 `report/` 目录。
-3. 在分享设置中选择谁能访问报告。
+新报告记录 Browser Eval 构建版本和选定的评测版本，并保留代码与输入哈希。结果比较规则见[版本说明](../docs/benchmarks.md#benchmark-editions)，历史数据见[参考输入](../docs/reference-inputs.md)。
 
-[Artifact Site](https://github.com/lexmount/artifact-site) 已开源，支持自行部署、报告版本管理和访问权限。本地报告无需托管账户，也不会自动上传。
-
-示例运行生成诊断报告。正式 benchmark 发布需要通过所选轨道的认证和发布检查；上传报告本身不代表结果已通过认证。

+## Web Search integration
+
+LexBench Web Search is installed from the immutable commit in `pyproject.toml` and `uv.lock`. Its task files and scoring code have one owner in that repository. Browser Eval provides providers, model/human annotation collection, latency/billing collection, audits and report publication. Report-specific execution profiles and receipts live with external evidence, selected explicitly by the caller. No sibling checkout is required.
+
+`uv run --frozen lexbench-websearch validate scenarios-v1` checks the installed definitions. The harness resolves explicit dataset/field/hash references before freezing a run.

+# Web Search API evaluation
+
+This track compares native search responses before an answering model is added. An explicit external profile selects participants, output options, result budget and datasets. Shared titles and snippets support retrieval relevance comparisons; optional summaries and page bodies are evaluated separately.
+
+[LexBench Web Search](https://github.com/lexmount/lexbench-websearch) owns task populations, provenance, reference qualifications and deterministic scoring. Browser Eval imports its pinned package directly. Store the instance selector, execution profiles, publication target and any hash-bound historical evidence authority beside external evidence. Pass the selector with `--profile`; there is no repository default or implicit published report. The collector resolves benchmark references before freezing run inputs. Historical standalone profiles keep their original bytes.
+
+## Run a comparison
+
+Put `LEXMOUNT_SEARCH_API_KEY`, `DEEPSEEK_API_KEY`, and `BOCHA_API_KEY` in the repository `.env`. Obtain a DeepSeek key from [its console](https://platform.deepseek.com/api_keys), a Bocha key from [its platform](https://open.bochaai.com/), and a Lexmount key from the service administrator. Never put credentials in profiles or evidence.
+
+```sh
+uv run --frozen python scripts/run_certified_benchmark.py web-search \
+  --profile /absolute/instance/current.json \
+  --output "$HOME/.browser-eval/web-search/new-run"
+uv run --frozen python scripts/build_search_report.py \
+  --source "$HOME/.browser-eval/web-search/new-run" \
+  --content /absolute/path/content.json \
+  --output /absolute/path/report --language zh
+```
+
+Use a new output directory for every collection. The frozen profile declares every query, method, result count, timeout, retry rule and price before calls. New cohorts use `protocol.order="complete provider batches"` (the default when omitted): all cases and rounds for one provider finish before the next provider starts. Explicit rotation remains supported only to continue or reproduce frozen historical cohorts. When the profile enables retries, a transport, HTTP or invalid-response failure receives one retry; a valid empty response does not. The final response is the one logical result, while every physical call is retained. A missing credential fails before calls or output creation.
+
+## SERP providers and finite quotas
+
+SERP profiles select providers through the same collector and renderer. Supported adapters include Lexmount, Browserbase Parallel Advanced, Bright Data Google Light JSON and Serper Google. Keep each report's profile, selected participants and publication target alongside its external evidence. These services use different upstream indexes; the comparison measures their delivered rankings.
+
+Configure `LEXMOUNT_SEARCH_API_KEY`, `BROWSERBASE_API_KEY`, `BRIGHTDATA_API_KEY` and `SERPER_API_KEY` in the repository `.env`. Browserbase Search does not require a browser session. Bright Data requires a SERP zone in the profile's `output_options.zone`; its account key alone does not identify the product configuration. Acquire keys from the [Browserbase dashboard](https://www.browserbase.com/overview), [Bright Data console](https://brightdata.com/cp/start), [Serper](https://serper.dev/) and the Lexmount deployment administrator.
+
+The profile requests five results and evaluates the first five native organic entries, preserving their order. Complete native responses remain bound evidence, including any extra results. Lexmount's public configuration selects `output_options.interface=public` and sends only `query` and `limit`; historical profiles retain their original request contract. Source-specific tasks express their domain restrictions through equivalent `site:` operators on the public interfaces. Native titles and snippets stay separate from page bodies and generated answers; a provider's missing snippet remains empty.
+
+Use the certified entry above with an explicit external `--profile /absolute/path/serp-profile.json`. Set rounds and retries to fit the smallest account allowance. `max_calls_per_method` accepts a shared integer or a complete method-to-limit map. It rejects an unaffordable full matrix before network calls and counts retained calls, including resume archives, before further spending. Record earlier configuration probes and the remaining reserve in the profile. Check the remaining balance before another collection.
+
+For a proven native-interface change during an interrupted collection, use `--resume --execution-revision /absolute/revision.json`. The `web-search-execution-revision/1` contract binds the previous and replacement profile hashes, root cause, complete superseded method scope and relative hash-bound evidence files. Only endpoint, native output options and budget metadata may change; tasks and measurement controls stay fixed. The collector preserves every unaffected result, archives displaced calls and their original contract, and recollects the complete changed method. Later resumes retain complete logical calls so another interruption does not spend unaffected providers' quotas again. The receipt distinguishes current physical calls from the total retained historical calls.
+
+Reference responses are captured before and after collection, with immutable hashes. The identity-scoped contract requires complete successful responses containing predeclared publisher or document identifiers. Volatile page chrome may change; missing identities prevent certification. `--diagnostic` preserves the full matrix for investigation and cannot certify a release. Anchor hits test only supplied known-page URLs. Dataset composition and source attribution come from the selected benchmark version.
+
+## Metrics and limits
+
+- Known-page Hit@5 and reciprocal rank use declared anchors. They are not full-web recall or overall answer accuracy.
+- Domain fraction tests host boundaries, excluding suffix lookalikes. Empty responses have no domain fraction; list fill and error counts remain visible.
+- Duplicate fraction uses conservative URL normalization. Semantic query parameters are preserved.
+- Factual probes match published supporting URLs and reference-answer cues. A versioned assessment revision interprets explicit accepted ranges and alternatives from the published answer; historical literal metrics remain reproducible from unchanged collection profiles. Preview fields and all delivered text are evaluated separately. Source matching is not whole-web recall; phrase presence is not semantic correctness. A separate diagnostic excludes explicitly named benchmark mirrors without promoting later results.
+- Full scenario relevance uses complete named human annotations, or an explicitly selected frozen model through `scripts/judge_search_relevance.py`. Both produce nDCG@5, Precision@5 and Success@5 through the same scorer. Model inputs omit provider identities and original ranks; retained requests, responses and quoted fields bind every label. Empty and all-zero pools remain in the population. Pass the resulting evidence with `--relevance`; label model judgments clearly.
+- Snippet, summary and content lengths count Unicode characters. Text quantity does not establish correctness or source faithfulness.
+- Client wall time includes request setup, network transfer, response bytes and any declared retry. Mean, median and nearest-rank P95 share each declared cohort's complete query population. Successful nonempty calls are reported separately. Serial latency does not measure throughput or an SLA.
+- Prices remain in their native currencies. Empty DeepSeek successes are free under its published rule. Transport failures have unknown billing. Lexmount cost stays unavailable until pricing is supplied. Estimates are not invoices and exclude downstream models and extra fetches.
+
+Raw response bodies, declared requests, transport errors, timings, cache metadata and source captures stay outside Git. Public result receipts reference raw responses by hash instead of duplicating their full text; checks reconstruct normalized results and verify both their count and content hash. The build verifies the complete matrix, hashes and derived metrics. Both report languages share the same evidence. The performance page separates client duration, reported server duration, transfer time and overlapping upstream attempts; overlapping durations must not be added. Publication uses this track's own target binding and never borrows another report's site. Independent review is opt-in.
+
+## Checks and example
+
+Building validates the frozen evidence and scoring bindings. Use `--check` for a
+standalone page check, or run `--release-check` once before publication to validate
+pages, evidence and the focused reader receipt together. Scoring-input reuse skips
+HTML inspection. Packaging and uploading verify the accepted files rather than
+repeating the full report check. Combine `--release-check RECEIPT` with
+`--export-delivery DESTINATION` to validate and export in one pass.
+
+API capability research belongs in the main report’s bound `--content` input. The measured report owns interface tables, request specimens and supporting sources.
+
+```sh
+uv run --frozen python -m unittest discover -s tests/web_search
+uv run --frozen python -m harness.web_search.example --output /tmp/search-example
+uv run --frozen python scripts/build_search_report.py --output /tmp/search-example/report --check
+```
+
+The example is synthetic and labels its numbers accordingly. Report checks reject broken links, altered evidence, duplicate summaries, missing error details and incorrect winner markers. Before delivery, inspect each generated top-level tab once at the normal desktop layout. Responsive and theme behavior belongs to reusable renderer tests instead of every report release. A local report is not a certified public release.
+
+The separate full gate is `scripts/build_search_report.py --output /absolute/report --release-check /absolute/visual-receipt.json`. It binds the report manifest to one reviewed capture of each top-level tab. Link, evidence, filter and pagination structure is checked during generation. Keep this receipt and screenshots outside Git.
+
+Supplemental cohorts use the same collector with another explicitly selected frozen profile. Present completed cohorts in one report with `--source /absolute/primary-run --cohort social=/absolute/social-run`. Repeat `--cohort NAME=RUN` for additional non-overlapping cohorts. The builder verifies each source independently, rejects duplicate cases and incompatible execution protocols, and renders one query inventory and one result inventory with group filters. The overall table describes saved calls across the fixed query mix; per-cohort timing remains visible and does not become a new same-window measurement. Optional external content supplies bilingual `cohort_labels`. Collection profiles and receipts remain immutable. `--site-prefix` is available when a separately requested nested report is needed. Qualified equivalent-page corrections use `--identity-correction /absolute/path/to/qualified-correction.json`: the report retains the collection profile, original evidence and an explicit before/after scoring receipt. This changes neither calls nor latency. A source observation must prove each alias and the correction must name its cause and regression controls.
+Each report has its own external publication authority. It binds the frozen collection profile, report manifest, scoring evidence, archive and exact remote version. Update this binding after a successful upload; preserve the collection profile and use the expected remote version for subsequent updates.
+
+
+Reader-oriented content can select `reading_model` and supply `reading_sections`
+with stable keys, bilingual titles and navigation labels. Sections target those
+keys through `page`; `lead` and `summary` surround the measured opening table.
+Use `specimens` to select a saved case, provider, result position and text fields
+rather than transcribing provider output. Provenance filters are separate from
+collection-group filters: an original community query can belong to any batch.
+The inventory calls URL anchors “predeclared target pages” because identity
+captures are not complete reference answers or relevance judgments.
+
+Supplementary research files use `assets` entries with a relative `source`, public
+`path` and `sha256`. Authored source links can set `evidence: true` to open a bound
+response in the shared dialog. The same asset path works in both generated
+languages. These examples do not enter the measured cohort merely by being
+included in the report. Release checks bind the authored explanation, actual
+specimens, source-filter populations and chapter visibility to the public build.
+
+For hosts with a file-count limit, export a checked report with
+`--output /absolute/report --export-delivery /absolute/new-delivery-directory`.
+This preserves the renderer's pages and raw responses in one compressed file per
+case, with shared detail and evidence viewers. The export verifies every original
+page and response against its source hash. It changes storage and navigation only;
+it does not rescore results. Run the full release gate on the canonical report and
+exercise the exported viewers on the target host before delivery.
+
+Collection stops after the declared retry if a participant returns HTTP 401 or
+402. Resolve the account problem before continuing with the same certified entry
+point and `--resume`. Resume requires the unchanged frozen profile and reference
+inputs. Complete unaffected cases remain unchanged; all configurations of an
+account-failed or incomplete case are collected again. The prior result stream,
+displaced responses and implementation snapshot remain hash-bound in the run's
+resume archive. A complete receipt is issued only after the entire original
+matrix and final reference checks pass. Record the interruption when interpreting
+collection windows; the pause is not API latency.
+
+## Three-provider presentation and annotation revisions
+
+External report content selects `presentation: comparison-report`, `comparison_methods`, optional `comparison_labels`, and explicit `metric_populations`. With `independent_benchmarks`, benchmark-root populations partition all cases; auxiliary diagnostic groups may overlap. The builder validates complete original runs before projecting the selected methods. Missing method-query cells fail closed. An `assessment_revision` adds independently qualified reference pages and versions answer matching without new provider calls. It retains original profiles, changed metrics and source observations. Added references must be identified independently of provider outputs; describe their observation date and scope accurately.
+
+The original SimpleQA Verified task measures closed-book model answers using a model grader. This report's source-hit, reciprocal-rank and lexical-cue checks are retrieval adaptations, not official benchmark accuracy. The frozen source version, input-length selection and adapted metrics belong on the dataset and methodology pages.
+
+Results analysis provides a same-query outcome explorer and paginated output columns generated from the method registry. Unknown judgments remain separate from misses. The delivery exporter rewrites dynamic detail links as well as ordinary HTML links, preserving language and exact case evidence. Release acceptance operates filters, pagination and dynamic evidence navigation in addition to the standard success/failure workflows.
+
+## Full in-house relevance annotation
+
+Export the candidate pool from an existing checked report:
+
+```sh
+uv run --frozen python scripts/build_search_report.py --output /absolute/report --export-annotations /absolute/new-annotation-directory
+```
+
+Open `index.html` in the exported directory. It covers every in-house query and
+pools all participants' top-five URLs without displaying provider names or ranks.
+Annotators assign 0–3 relevance grades, inspect source pages when needed, and
+confirm every query, including queries with no candidates. The page saves progress
+in that browser and exports a complete JSON file. It does not call a model or
+pre-fill grades.
+
+Pass the completed file to the normal build with `--relevance`. Import verifies
+the frozen packet, every query and candidate, and the named annotator. Explicitly
+authorized model runs bind exact prompts, requests, responses and quoted evidence.
+Sampled in-house label sets are rejected. Fixed labels produce nDCG@5
+and Precision@5 deterministically. Duplicate URLs earn no additional credit;
+missing slots count toward the five-slot denominator. A query with no relevant
+pooled candidate receives zero nDCG and precision and stays in the population.
+Known-URL discovery and site constraints remain separate diagnostics.
+
+For explicitly authorized model annotations, run `scripts/judge_search_relevance.py`
+with `--report`, `--output`, `--model` and `--base-url`. Supply the credential through
+`SEARCH_JUDGE_API_KEY`; do not put credentials in CLI arguments. The runner freezes
+its contract, retains each response, resumes completed queries and refuses changed
+inputs. Import its `relevance.json` through the existing report `--relevance` option.
+Model annotations are labeled separately from human annotations. The rubric uses
+0–3 grades, with nDCG@5, Precision@5 (grade ≥2), and Success@5 (at least one grade 3).
+
+Site-family domain lists and explicit native-source routes are mandatory judge constraints. Domain lists on
+ordinary searches remain source diagnostics; explicit constraints in the query
+still apply under the common rubric.
+Bind official-source alternatives with `--source-requirements` when judging a
+report, or embed them in a frozen packet. The program checks URL eligibility;
+the model receives titles, snippets and eligibility flags without source URLs.
+Ineligible candidates score zero while their original model grades remain in
+the evidence. A changed frozen rubric requires an explicit zero-search-call
+`relevance_revision` in report content; build and check verify its input bindings.
+Retrieval reports also use supporting-source hits as the default factual check
+in same-task comparisons. Answer text remains an optional diagnostic.
+
+When correcting source requirements, preserve the original relevance evidence
+and pass it to the judge with `--reuse-evidence /absolute/relevance.json`.
+The runner inherits calls whose judge requests are unchanged and judges only
+changed requests. Report content records `relevance_revision.source_rule_correction`
+with schema `web-search-source-rule-correction/1`, a `root_cause`, `provider_calls: 0`,
+and the paired `regression_ids` listed by `SOURCE_RULE_REGRESSIONS` in the relevance
+module. Set `before_relevance_sha256` to the SHA256 of the predecessor serialized
+with `json.dumps(predecessor, ensure_ascii=False, sort_keys=True).encode()`.
+`changed_case_ids` lists exactly the queries with changed candidate eligibility
+flags; `new_judge_case_ids` lists the current plan minus `inherited_case_ids`.
+Metadata changes that leave judge inputs unchanged reuse their original calls.
+Build and check verify the predecessor, original physical receipts, case lists
+and regression controls before accepting the correction.
+
+
+## Independent result audit
+
+Independent audit is a separate, explicitly requested stage. Freeze the requested scope before reviewers see prior scores:
+
+```sh
+uv run --frozen python scripts/review_search_results.py freeze \
+  --report /absolute/report --output /absolute/new-review --model MODEL_ID
+```
+
+Freeze requires an explicit model ID. Failure-only review is the default; a full
+review requires `--scope all --authorization` with the user authorization record.
+Run frozen packets through the maintained CLI backend and collect its completed
+results:
+
+```sh
+uv run --frozen python scripts/review_search_results.py run --review /absolute/review --workers 4
+uv run --frozen python scripts/review_search_results.py collect --review /absolute/review --require-complete
+```
+
+An unavailable model or failed job earns no coverage. Successful packets are
+reused on resume, and changed inputs are rejected. Execution records are
+operator-attested and hash-bound; they are not third-party signed attestations.
+
+Coverage counts questions, method outputs and pooled relevance candidates
+separately. Every selected output, including empties and errors, requires a review
+record. Unreviewed successful outputs are counted explicitly. A factual reference
+can be accepted only with an independent frozen source excerpt; tested provider
+outputs cannot substitute for it.
+Long document checks cover delivered structure and the query-relevant passages
+in complete saved bodies; review coverage is not a claim that every unrelated
+sentence in every returned document has been fact-checked. Provider limitations,
+dataset defects and scoring defects remain distinct findings. Completed review
+and successful provider output are different states; findings require explicit
+disposition before the final audited report is released.
+
+A formal reviewed release passes `--review /absolute/review-evidence.json` to
+`build_search_report.py`. It must contain all opinions in the declared scope and
+an adjudication for every dataset issue, output issue and finding. Each decision
+binds the original opinion hash, its resolution, reason and evidence. Provider
+limitations are recorded separately from corrected evaluation defects. The build
+rejects incomplete declared coverage, changed reviewer opinions, unmatched outputs and open
+findings; the release check also verifies rendered summary and detail evidence.
+
+A source-rule correction can pass `--reuse-evidence /absolute/relevance.json` to
+the judge entry point. It revalidates the predecessor and reuses a call only when
+its complete request is unchanged. Changed inputs receive new physical receipts;
+the resulting evidence retains the predecessor and identifies every inherited
+case. Transport or model configuration changes cannot silently reuse old calls.
+
+A completed independent reference review may quarantine a defective factual query
+from every participant’s quality denominator. The original task, response and
+metrics remain inspectable; all-call latency and cost retain the entire cohort.
+Each exclusion must bind a dataset finding and an explicit adjudication.
+
+### Comparison report reading layout
+
+The comparison home owns the compact quality/latency/price summary and same-scope
+page/site discovery comparison. Detailed relevance and same-query specimens belong
+to the quality page; collection-specific timing, server diagnosis and billing share
+one performance page. The dataset page owns current inputs and provenance; the result
+explorer shows one query per output page without truncating full summaries or dropping
+providers. Methodology and independent review remain linked appendices. Redundant
+standalone cost and interpretation routes are not generated in this layout.
+
+## Publish a replacement
+
+`scripts/publish_search_report.py` freezes the checked report, source receipts,
+content, visual evidence and lossless delivery archive before any upload. Pass
+`--report`, `--visual-receipt`, `--content`, each `--source COHORT=RUN` and a new
+`--output` directory inside `BROWSER_EVAL_DATA_HOME`. The next release is checked
+against its own frozen inputs while the existing site identity and remote version
+remain locked. `--resume` reuses the same plan and idempotent upload operation.
+The command records the activated version in this track’s publication target.
+
+Review CLI jobs use the signed-in Codex account in an isolated configuration,
+copying only its authentication file. Search-provider and model-judge API keys
+continue to come from the repository `.env`; they are not passed to review jobs.
+
+Publication also requires `--profile /absolute/instance/current.json` for a new plan. The plan pins that selector; resume reuses it and rejects changed inputs. Publishing updates only the selected external target receipt. New report builds with legacy evidence must explicitly bind `assessment_authority` by relative path and SHA-256 in the selector. The checked report carries that authority as a hash-bound asset; no report-specific exception list is compiled into the package.
+
+Interface text is maintained in `messages.json`. Source-language policy checks reject inline Chinese in the Search renderers and report-instance schemas in `evaluation/`, including renamed files. Synthetic examples and benchmark task definitions remain versioned.
