# OpenClaw v0.2.0 — Stage F Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. Each task is one TDD pass: write failing tests → run → implement → run → commit.

**Goal:** Land the `agentsec evaluate` command that orchestrates the existing remote-test pipeline (Stage A–C) and server-audit pipeline (Stage D–E), feeds them into the spec §9 normalized scorer, and emits the six-artifact report directory specified in spec §9.3 (`remote-report.md`, `server-audit-report.md`, `combined-report.md`, `findings.json`, `threat-intel-snapshot.yaml`, `audit-log.jsonl`). Adds the `OpenClawTargetConfig` Pydantic model for `openclaw-target.yaml` (spec §8.2) and closes the Stage C M4 carryover (`_UnreachableLLM` Judge ABC bypass) by introducing a real `NoOpJudge`.

**Architecture:**

- `src/agentsec/config.py` (new) — Pydantic v2 model `OpenClawTargetConfig` mirroring spec §8.2. Loads YAML via `OpenClawTargetConfig.from_yaml(path)`. Both `remote` and `server_audit` sub-sections are optional, so `agentsec evaluate` can run either half alone (the other half's score becomes `None` and the combined score reweights — spec §9.2). `extra="forbid"` at every level rejects typos before the orchestrator partially executes.
- `src/agentsec/scoring.py` (new) — pure data-in / data-out scoring per spec §9.1–9.3. Public surface:
  - `category_score(passed, failed, worst_failed_severity, *, aggregation) -> CategoryScore`
  - `remote_score(category_scores: list[CategoryScore], category_weights: dict[str, float]) -> float | None`
  - `dedupe_findings(findings: list[Finding]) -> list[Finding]` (server-side fingerprint dedupe — already in `run_server_audit`, lifted here as a pure function so the Stage F report can dedupe across both halves)
  - `server_score(findings: list[Finding]) -> int`
  - `coverage_triple(planned, executed, scored, error) -> CoverageTriple`
  - `combined_score(remote, server, *, w_r=0.5, w_s=0.5) -> CombinedScore`
  - `grade_letter(score, *, low_coverage) -> str`
  - `score_evaluation(remote_results, server_findings, *, planned_count, config) -> EvaluationScore` — top-level wiring used by the CLI.
- `src/agentsec/evaluator/no_op_judge.py` (new) — `NoOpJudge(Judge)` that raises a typed `NoOpJudgeInvoked` when `evaluate()` is called. Replaces the inline `_UnreachableLLM` sentinel in `cli.py` (Stage C M4). Used as the LLM slot in `JudgeRouter` for deterministic-only suites; the Router's dispatch invariant means `evaluate()` is unreachable for those suites, so the typed error is defensive only (fires only on a Router bug or hand-built `judge_type=llm` test in a deterministic-only suite).
- `src/agentsec/reports/json_report.py` (new) — two writers:
  - `write_findings_json(findings, path)` — pretty-printed, sorted-keys JSON dump of already-redacted findings.
  - `write_threat_intel_snapshot(referenced_refs, threat_intel_path, out_path)` — projects `threat_intel.yaml` rows whose `id` is in the union of all `Finding.threat_refs` and `TestCase.threat_refs` consumed during the run.
- `src/agentsec/reports/markdown.py` (rewritten) — three renderers replacing the current single `render_markdown_report`:
  - `render_remote_report(agent_name, results, evaluation_score) -> str` (extends today's content with a category-score table and a coverage triple)
  - `render_server_audit_report(report, *, profile_name, remote_home, low_assurance, server_score) -> str` (lifts the inline string-builder currently in `cli.py:server_audit`)
  - `render_combined_report(agent_name, evaluation_score, *, remote_present, server_present) -> str` (new — overall grade, links to the other two reports, surfaces LOW_COVERAGE banner)
  Each renderer emits the same `<!-- meta:... -->` HTML comment style Stage E introduced so downstream parsers (CI, the eventual web viewer) can keep using stable selectors.
- `src/agentsec/cli.py` (modified) — adds `agentsec evaluate --config <yaml> --output <dir>` orchestrator. Internally it reuses the building blocks from `agentsec run` and `agentsec server-audit` rather than shelling out to itself; the existing two commands stay (so `agentsec run` for one-shot suites and `agentsec server-audit` for one-shot audits keep working unchanged). The `_UnreachableLLM` block is replaced with `NoOpJudge`.

**Tech stack:** Python 3.11+, Pydantic v2, `typer`, `rich`, `pyyaml`, pytest + pytest-asyncio. **No new runtime dependencies** — every primitive Stage F needs is already in the dependency tree.

**Branch strategy:** Already cut `phase-2/openclaw-eval-stage-f` from `origin/main` (`be97ca7` Stage E squash). PR targets `main`. Older `phase-2/openclaw-eval-stage-{b,c,d,e}` branches are preserved on origin (`--delete-branch=false`); leave alone.

**Exit criteria (parent plan §Stage F + spec §9.x + §10.1 prep):**

- `agentsec evaluate --config openclaw-target.yaml --output ./report-2026-04-28/` runs end-to-end against a stubbed adapter + stubbed SSH transport, exits 0, and produces all six artifacts in the output directory: `remote-report.md`, `server-audit-report.md`, `combined-report.md`, `findings.json`, `threat-intel-snapshot.yaml`, `audit-log.jsonl`.
- The `--config` file follows spec §8.2; `OpenClawTargetConfig` rejects unknown top-level keys with a typed Pydantic error.
- Coverage triple uses `planned` (load-time count) as denominator (closes OE-AUD3-006). `verdict_coverage` and `error_rate` are computed and surfaced; when `verdict_coverage < 0.7` or `error_rate > 0.1` the combined report carries a `LOW_COVERAGE` banner and `grade_letter` returns `INSUFFICIENT_COVERAGE` instead of A/B/C/D/F (closes OE-AUD-009).
- Identical server-side findings (same `fingerprint = sha256(check + title + canonical_evidence)`) collapse to one entry in `findings.json` and in `server-audit-report.md` (closes OE-AUD2-011).
- When one of `remote_score` / `server_score` is `None` (because that half was not configured or had `denom == 0`), the combined score reweights to give the other half full weight (`w_r=1.0` or `w_s=1.0`); when both are `None`, combined is `None` and the report says "no scorable evidence" rather than reporting `0`.
- The Stage C M4 carryover is closed: `git grep -n "_UnreachableLLM" src/` is empty after Stage F; `NoOpJudge` is the only judge that lives in the LLM slot of the Router for deterministic-only suites.
- Local gates green: `.venv/bin/pytest -q`, `.venv/bin/ruff check src/ tests/`, `.venv/bin/python scripts/check_threat_refs.py`, `.venv/bin/python scripts/build_cve_db.py --check`, hardcoded-path grep guard (`git grep -nE '/var/log/openclaw|~/.openclaw|/etc/systemd|/Library/' src/agentsec/audit/checks/` returns zero hits — Stage E invariant must stay green).
- `tests/integration/test_evaluate_smoke.py` runs the full pipeline against a mock OpenClaw HTTP server + stub SSH transport on Linux and macOS CI.

**Audit findings closed by Stage F:** OE-AUD-009 (scoring + low-coverage handling), OE-AUD2-011 (server-side fingerprint dedupe in scorer), OE-AUD3-006 (coverage denom = planned).

**Memory tech-debt items addressed:** M3 + M4 from the Stage C carryover list. M3 (`TestResult.verdict` / `observations` typing) becomes formally justified — Stage F doesn't tighten the field types because the runner already has typed `JudgeVerdict` in flight and only serializes to dict at TestResult-construction time; the typed-model migration is a Stage G+ refactor. M4 (`_UnreachableLLM`) is closed in Task F.0.b.

**Scope explicitly deferred (out of v0.2.0 / handled in Stage G):**

- **Mock OpenClaw end-to-end with full sample report directory committed** — Stage G (spec §10.1). Stage F's smoke test asserts on the artifact set; Stage G commits a "golden" sample.
- **`agentsec ioc-update` auto-feed** — vNext (spec §11; CHANGELOG already records this).
- **Web-rendered report viewer** — out of scope for v0.2.0 entirely.
- **`scoring.severity_aggregation: weighted_mean`** — implemented in `category_score`'s `aggregation` parameter so the config switch is honored, but the default stays `worst` per spec §9.2; CHANGELOG calls out the choice. (Switch toggles; not a deferral, but worth flagging here for clarity.)
- **Custom category weights from config** — implemented as `scoring.category_weights: dict[str, float] | None` in the config model; default is equal weight (1.0) for every category that produced a score. This is exposed for completeness; the v0.2.0 default sample config does **not** set weights.

## Self-review checklist (run before claiming the stage done — at Task F.4.b)

Before opening the PR, verify each:

- [ ] `agentsec evaluate --config <example> --output <dir>` produces exactly six artifacts; `ls <dir>` matches the spec §9.3 list.
- [ ] `git grep -n "_UnreachableLLM" src/ tests/` returns zero hits (Stage C M4 closed).
- [ ] `git grep -nE '/var/log/openclaw|~/.openclaw|/etc/systemd|/Library/' src/agentsec/audit/checks/` still returns zero (Stage E invariant intact).
- [ ] `.venv/bin/pytest -q` green on Linux locally; CI macOS job green on the PR.
- [ ] `.venv/bin/ruff check src/ tests/` green.
- [ ] `.venv/bin/python scripts/check_threat_refs.py` green.
- [ ] `.venv/bin/python scripts/build_cve_db.py --check` green.
- [ ] CHANGELOG has a Stage F entry summarizing the new command + scoring + report split + the `NoOpJudge` cleanup.
- [ ] ROADMAP.md `阶段 F` checkbox is `[x]`.
- [ ] Three-reviewer parallel pass on the final diff (Option D pattern that found 7 Important findings on Stage E) — apply each Important finding before opening the PR.

---

## Pre-flight (do once at start of stage)

The branch was already created when this plan was written. The first three pre-flight items confirm the baseline; PF-4 is the one-line ROADMAP fix that should land as the first commit on the branch (so the rest of Stage F can build on the pre-flight commit without churn at the end).

- [ ] **PF-1: Confirm clean baseline on `phase-2/openclaw-eval-stage-f`**

```bash
git status -sb
git log --oneline -3
.venv/bin/pytest -q
.venv/bin/ruff check src/ tests/
.venv/bin/python scripts/check_threat_refs.py
.venv/bin/python scripts/build_cve_db.py --check
```

Expected: branch tracks `origin/main`; HEAD is `be97ca7`; `pytest` reports `416 passed`; ruff/threat-refs/build_cve_db all green.

- [ ] **PF-2: Confirm Stage E invariants still hold**

```bash
git grep -nE '/var/log/openclaw|~/.openclaw|/etc/systemd|/Library/' src/agentsec/audit/checks/ || echo OK
git grep -n "Real SSH local-forward is not implemented" src/ || echo OK
```

Expected: both print `OK`. If anything else, stop and investigate before starting Stage F (the regression must come from the merged Stage E PR and is unrelated work).

- [ ] **PF-3: Commit this plan as the first commit on the branch**

```bash
git add docs/superpowers/plans/2026-04-28-stage-f.md
git commit -m "docs(plan): add Stage F sub-plan (evaluate command + scoring + reports)"
```

Expected: working tree clean; one new commit on `phase-2/openclaw-eval-stage-f`.

- [ ] **PF-4: Tick `阶段 F` to in-progress in ROADMAP**

ROADMAP.md still shows Stage F as `[ ] 阶段 F：…`. Leave the `[ ]` in place during Stage F implementation; flip to `[x]` in Task F.4.b alongside the CHANGELOG entry. (We only commit ROADMAP changes once per stage — that's the established Stage D / Stage E convention; flipping mid-stage churns the file unnecessarily.)

No commit needed for PF-4.

## Task F.0.a: `OpenClawTargetConfig` Pydantic model (spec §8.2)

**Files:**
- Create: `src/agentsec/config.py`
- Test: `tests/test_config_model.py`
- Reference fixture: `tests/fixtures/openclaw-target.example.yaml` (new — used by F.4.a too)

"""OpenClaw target configuration model (spec §8.2).

This is the only module that knows the shape of `openclaw-target.yaml`. The
CLI's `evaluate` command loads through `OpenClawTargetConfig.from_yaml(path)`;
every field is validated up front so partial-execution failures (server-audit
runs, then config is wrong, then SSH connections leak) are impossible.

Both `remote` and `server_audit` are optional; at least one must be present.
This lets the same config-driven flow handle "remote-only" and "audit-only"
deployments without a second config schema.

## Task F.0.b: `NoOpJudge` — close Stage C M4

**Files:**
- Create: `src/agentsec/evaluator/no_op_judge.py`
- Test: `tests/test_no_op_judge.py`

**Why:** Today's `cli.py:run` defines an inline `_UnreachableLLM` class with `# pragma: no cover` to populate the LLM slot of `JudgeRouter` for deterministic-only suites. It bypasses the `Judge` ABC contract (missing the `Judge` parent class) and lives outside the typed evaluator package — that's the M4 carryover from Stage C. Stage F replaces it with a proper `Judge` subclass that can be reused by the new `evaluate` orchestrator and unit-tested directly.

- [ ] **Step 1: Write the failing tests**

```python
# tests/test_no_op_judge.py
import pytest

from agentsec.evaluator.no_op_judge import NoOpJudge, NoOpJudgeInvoked
from agentsec.evaluator.base import Judge


def test_no_op_judge_is_a_judge_subclass():
    assert issubclass(NoOpJudge, Judge)


@pytest.mark.asyncio
async def test_no_op_judge_raises_when_invoked():
    judge = NoOpJudge()
    with pytest.raises(NoOpJudgeInvoked, match="LLM judge is not configured"):
        await judge.evaluate(test_case=None, observation=None)  # type: ignore[arg-type]


def test_no_op_judge_invoked_is_runtime_error_subclass():
    # Lets callers catch it as RuntimeError without importing the typed class.
    assert issubclass(NoOpJudgeInvoked, RuntimeError)
```

- [ ] **Step 2: Run tests to verify they fail**

```bash
.venv/bin/pytest tests/test_no_op_judge.py -v
```

Expected: `ModuleNotFoundError: No module named 'agentsec.evaluator.no_op_judge'`.

- [ ] **Step 3: Implement**

```python
# src/agentsec/evaluator/no_op_judge.py
"""No-op judge — populates the LLM slot of a JudgeRouter when no Anthropic
key is available because the suite is deterministic-only.

JudgeRouter dispatches per `TestCase.judge_type`: a deterministic-only suite
never reaches this branch. NoOpJudgeInvoked therefore fires only when:
  - a hand-built TestCase has `judge_type="llm"` in a deterministic-only run, or
  - JudgeRouter has a dispatch bug.

Both cases are programmer errors, so the typed RuntimeError subclass surfaces
the failure with a useful message instead of silently passing.

Closes Stage C M4 carryover (the `_UnreachableLLM` inline class in cli.py).

## Task F.0.c: Replace `_UnreachableLLM` in `cli.py:run` with `NoOpJudge`

**Files:**
- Modify: `src/agentsec/cli.py:127-136`
- Test: `tests/test_cli_judge_router.py` (extend if asserts on the literal class name)

- [ ] **Step 1: Read the current site**

```bash
grep -n "_UnreachableLLM\|NoOpJudge" src/agentsec/cli.py tests/
```

Expected: only matches in `cli.py` (the inline `_UnreachableLLM` block) and any tests that mention it. None of the existing tests assert on the literal class name (they all instantiate via `agentsec run`), so this is a pure refactor.

- [ ] **Step 2: Write a failing test that pins the new behavior**

```python
# tests/test_cli_judge_router.py — APPEND to the existing file

def test_deterministic_only_suite_uses_no_op_judge_in_llm_slot(monkeypatch, tmp_path):
    """If the suite is deterministic-only, AGENTSEC_JUDGE_API_KEY is not
    consulted and NoOpJudge fills the LLM slot. (Regression: pre-F.0.c the slot
    was an inline `_UnreachableLLM` outside the Judge ABC — Stage C M4.)"""

        # Call the real __init__ so the rest of `run` works.
        original_init(self, llm=llm, deterministic=deterministic, hybrid=hybrid)

    original_init = JudgeRouter.__init__
    monkeypatch.setattr(JudgeRouter, "__init__", _capture)

    monkeypatch.delenv("AGENTSEC_JUDGE_API_KEY", raising=False)
    monkeypatch.delenv("ANTHROPIC_API_KEY", raising=False)

    assert result.exit_code == 0, result.stdout

(Note: the helper accesses `registry._registry` to clean up; if the registry exposes a public `unregister`, prefer that.)

- [ ] **Step 3: Run test to verify it fails**

```bash
.venv/bin/pytest tests/test_cli_judge_router.py::test_deterministic_only_suite_uses_no_op_judge_in_llm_slot -v
```

Expected: FAIL — `captured["llm"]` is the inline `_UnreachableLLM`, not `NoOpJudge`.

- [ ] **Step 4: Apply the refactor**

Replace `cli.py:127-136` (the `else: class _UnreachableLLM: ...; llm = _UnreachableLLM()` block):

```python
# in cli.py, near the top:
from .evaluator.no_op_judge import NoOpJudge

# at lines 116..142 (the existing if/else around llm construction):
needs_llm = any(tc.judge_type in {"llm", "hybrid"} for tc in test_cases)
if needs_llm:
    try:

    except Exception as exc:  # noqa: BLE001 — surface a friendly CLI error
        console.print(
            f"[red]error:[/red] suite includes llm/hybrid cases but "
            f"LLMJudge construction failed: {exc}. Set AGENTSEC_JUDGE_API_KEY "
            "or restrict the suite to judge_type=deterministic."
        )
        raise typer.Exit(code=2)
else:
    # Deterministic-only suite: NoOpJudge fills the LLM slot. JudgeRouter
    # never dispatches to it (closes Stage C M4 — was `_UnreachableLLM`).
    llm = NoOpJudge()

judge = JudgeRouter(
    llm=llm,
    deterministic=DeterministicJudge(),
    hybrid=HybridJudge(llm_judge=llm),

```

- [ ] **Step 5: Run tests to verify they pass + nothing regressed**

```bash
.venv/bin/pytest tests/test_cli_judge_router.py -v
.venv/bin/pytest -q
```

Expected: the new test passes; full suite still 416+ passed.

- [ ] **Step 6: Verify M4 closure**

```bash
git grep -n "_UnreachableLLM" src/ tests/
```

Expected: zero hits.

- [ ] **Step 7: Commit**

```bash
git add src/agentsec/cli.py tests/test_cli_judge_router.py
git commit -m "refactor(cli): replace _UnreachableLLM with NoOpJudge (closes Stage C M4)"

## Task F.2.b: `reports/markdown.py` — split into 3 renderers

**Files:**
- Modify: `src/agentsec/reports/markdown.py`
- Modify: `tests/test_markdown_report.py`
- Test: `tests/test_markdown_report.py` (extend with the two new renderers)

**Background:** today `markdown.py` exposes one `render_markdown_report(name, results) -> str`. The `agentsec server-audit` command builds its own server-audit Markdown inline in `cli.py:server_audit`. Stage F unifies both under `reports/markdown.py` and adds a third combined renderer.

- [ ] **Step 1: Write the failing tests**

Replace the body of `tests/test_markdown_report.py` with:

```python

```

- [ ] **Step 2: Run to verify they fail**

```bash
.venv/bin/pytest tests/test_markdown_report.py -v

Expected: ImportError on the new renderers.

- [ ] **Step 3: Rewrite `reports/markdown.py`**

```python
# src/agentsec/reports/markdown.py
"""Markdown report renderers (spec §9.3).

Three renderers, all read-only (no I/O):

  - render_remote_report — replaces v0.1.x's `render_markdown_report`; adds
    a "Score" section driven by `EvaluationScore`.
  - render_server_audit_report — lifts the inline string-builder out of
    `cli.py:server_audit` so it can be unit-tested.
  - render_combined_report — top-level grade + links into the two halves.

`<!-- meta:... -->` HTML comments give downstream consumers (the eventual

## Task F.3.a: `cli.py:evaluate` — orchestrator

**Files:**
- Modify: `src/agentsec/cli.py`
- Test: `tests/test_cli_evaluate.py` (new)

**Approach:** the new `evaluate` command is mostly a glue function. It loads `OpenClawTargetConfig`, runs the existing `run_suite` for the remote half, runs `run_server_audit` for the server-audit half (mirroring `cli.py:server_audit`), feeds both into `score_evaluation`, and writes the six artifacts. To keep `cli.py` readable, factor the per-half work into private helpers.

- [ ] **Step 1: Write the failing test**

```python
# tests/test_cli_evaluate.py
"""Smoke test for `agentsec evaluate` — feeds a 2-case fixture through a
stubbed adapter + stubbed SSH transport, asserts on artifact filenames."""

    assert "remote-report.md" in combined
```

- [ ] **Step 2: Run to verify it fails**

```bash
.venv/bin/pytest tests/test_cli_evaluate.py -v
```

Expected: `Usage: cli evaluate [OPTIONS]` returns "no such command" (or the test fails because `evaluate` is not registered). The exact failure mode depends on Typer's behavior for missing subcommands.

- [ ] **Step 3: Add the `evaluate` command + helpers in `cli.py`**

Add these imports at the top of `cli.py` (next to the existing imports):

```python
from .config import OpenClawTargetConfig

from .reports.markdown import (
    render_combined_report,
    render_remote_report,

Then append the new command (below `server_audit`, above `if __name__ == "__main__":`):

## Task F.3.b: refactor `cli.py:server_audit` to use `render_server_audit_report`

**Files:**
- Modify: `src/agentsec/cli.py:266-301` (the inline `md = [...]` block in `server_audit`)
- Test: existing `tests/audit/test_cli_server_audit.py` covers this; we just need its existing assertions to still pass.

This is a pure refactor — `server_audit` already builds the same Markdown the new `render_server_audit_report` produces; replace the inline list-building with a call to the renderer.

- [ ] **Step 1: Apply the refactor**

In `cli.py:server_audit`, replace lines 266..301 (the `md = [...]; ... (output / "server-audit-report.md").write_text(...)` block) with:

```python
    (output / "server-audit-report.md").write_text(
        render_server_audit_report(
            report,
            profile_name=profile.name,
            remote_home=remote_home,
            low_assurance=auth.low_assurance,
            server_score=None,  # one-shot server-audit doesn't compute a score
        )
    )
```

- [ ] **Step 2: Run tests**

```bash
.venv/bin/pytest tests/audit/test_cli_server_audit.py tests/integration/test_openclaw_stage_e_smoke.py -v
```

Expected: all green. The Stage E smoke asserts on `<!-- meta:profile value:linux -->` etc., which are now produced by `render_server_audit_report` — the test should pass without modification.

- [ ] **Step 3: Commit**

```bash
git add src/agentsec/cli.py
git commit -m "refactor(cli): use render_server_audit_report in server-audit command"
```

---

## Task F.4.a: integration smoke — full evaluate against mock OpenClaw

**Files:**
- Create: `tests/integration/test_evaluate_smoke.py`

This is a heavier-weight smoke test that exercises every Stage F primitive together. It mirrors `tests/integration/test_openclaw_stage_e_smoke.py`'s pattern but layers a 3-case YAML suite on top so the scorer sees real category buckets.

- [ ] **Step 1: Write the failing test**

```python
# tests/integration/test_evaluate_smoke.py
"""Stage F smoke: agentsec evaluate end-to-end with a 3-case suite + a stubbed
SSH transport that emits 2 server findings (1 high, 1 low) plus 1 duplicate.

Verifies:
  - All six artifacts in spec §9.3 are written.
  - findings.json contains 2 entries (duplicate collapsed by fingerprint).
  - combined-report.md contains the LOW_COVERAGE banner when verdict_coverage<0.7.
  - threat-intel-snapshot.yaml contains rows referenced by server findings.

git commit -m "test(integration): add Stage F evaluate smoke (6 artifacts + dedupe)"

## Task F.4.b: ROADMAP + CHANGELOG

**Files:**
- Modify: `ROADMAP.md`
- Modify: `CHANGELOG.md`

- [ ] **Step 1: Tick `阶段 F` in ROADMAP**

```bash
sed -i.bak 's|- \[ \] 阶段 F：归一化评分.*|- [x] 阶段 F：归一化评分 + `agentsec evaluate` + 报告渲染|' ROADMAP.md && rm ROADMAP.md.bak
```

Verify with `grep -n '阶段 F' ROADMAP.md` — should now show `[x]`.

- [ ] **Step 2: Append a Stage F entry to CHANGELOG**

Insert after the Stage E section (around line 9 of `CHANGELOG.md`):

```markdown
### Stage F — `agentsec evaluate` + scoring + reports (2026-04-28)

- New CLI subcommand: `agentsec evaluate --config openclaw-target.yaml --output ./report-…/`. Orchestrates the remote suite + server-audit halves and writes the six artifacts from spec §9.3 (`remote-report.md`, `server-audit-report.md`, `combined-report.md`, `findings.json`, `threat-intel-snapshot.yaml`, `audit-log.jsonl`).
- Added `OpenClawTargetConfig` Pydantic model (`src/agentsec/config.py`) for `openclaw-target.yaml`. Both `remote` and `server_audit` sub-sections are optional; at least one must be set. `extra="forbid"` rejects unknown keys at every nesting level.
- Added `agentsec.scoring` module implementing spec §9.1–9.3: `category_score`, `remote_score`, `dedupe_findings`, `server_score`, `coverage_triple`, `is_low_coverage`, `combined_score`, `grade_letter`, top-level `score_evaluation`. Coverage triple uses `planned` (load-time count) as denominator, not `executed` — closes OE-AUD3-006.
- `combined_score` reweights to 100% when one of remote/server is unavailable; both unavailable yields `None` rather than a fake `0` — closes OE-AUD-009.
- Identical findings (matching `Finding.fingerprint`) collapse before scoring and before writing `findings.json` — closes OE-AUD2-011.
- `verdict_coverage < 0.7` or `error_rate > 0.1` → grade is `INSUFFICIENT_COVERAGE` (not A/B/C/D/F), and the combined report carries a `LOW_COVERAGE` banner.
- Split `agentsec/reports/markdown.py` into three renderers: `render_remote_report`, `render_server_audit_report` (lifted from inline `cli.py:server_audit` builder), `render_combined_report`. The legacy `render_markdown_report(name, results)` is kept as a deprecated shim for one minor version.
- Added `agentsec/reports/json_report.py` with `write_findings_json` (sorted-keys, stable diffs) and `write_threat_intel_snapshot` (projects only the TI rows referenced by this run).
- Closed Stage C M4 carryover: replaced the inline `_UnreachableLLM` sentinel in `cli.py:run` with a real `NoOpJudge` subclass under `agentsec/evaluator/no_op_judge.py`. `git grep _UnreachableLLM src/ tests/` now returns zero hits.

**Audit findings closed by Stage F:** OE-AUD-009, OE-AUD2-011, OE-AUD3-006.
```

- [ ] **Step 3: Verify both files**

```bash
grep -n "阶段 F" ROADMAP.md
head -50 CHANGELOG.md
```

Expected: `[x] 阶段 F` line present; CHANGELOG starts with the Stage F section under `[Unreleased]`.

- [ ] **Step 4: Commit**

```bash
git add ROADMAP.md CHANGELOG.md
git commit -m "docs(stage-f): tick ROADMAP + add CHANGELOG entry for evaluate/scoring/reports"
```

## Task F.4.c: pre-PR three-reviewer parallel pass (Option D)

**Procedural — not a code task. Documented here so the executor doesn't skip it.**

Pattern that worked on Stage E: dispatch 3 parallel reviewer subagents on the diff and collect their findings before opening the PR. The Stage E batch found 7 Important findings the per-task reviews missed (`bug_001..007`).

- [ ] **Step 1: Confirm local gates still green**

```bash
.venv/bin/pytest -q
.venv/bin/ruff check src/ tests/
.venv/bin/python scripts/check_threat_refs.py
.venv/bin/python scripts/build_cve_db.py --check
git grep -nE '/var/log/openclaw|~/.openclaw|/etc/systemd|/Library/' src/agentsec/audit/checks/ || echo OK
git grep -n "_UnreachableLLM" src/ tests/ || echo OK
```

Expected: pytest 416+N green; ruff clean; threat-refs green; build_cve_db clean diff; both grep guards print `OK`.

- [ ] **Step 2: Dispatch three parallel reviewer subagents**

Send a single message containing three `Agent` calls in parallel — angle-distinct prompts:

  - **Reviewer 1 — Spec compliance**: read `docs/specs/openclaw-evaluation.md` §8.2 / §9.x, then audit Stage F's diff (config model field shapes, scoring formulae, coverage denom, low-coverage thresholds, artifact set in spec §9.3) for any drift from the spec.
  - **Reviewer 2 — Code quality / typing**: focus on `agentsec.scoring`, `agentsec.config`, the new `cli.py:evaluate` orchestrator, and the renderer split. Flag dict-of-Any anywhere a typed model would be safer; flag duplicated logic between `cli.py:server_audit` and `cli.py:evaluate` that should be a private helper; flag any silent-except branches.
  - **Reviewer 3 — End-to-end correctness**: read `tests/integration/test_evaluate_smoke.py` and the orchestrator. Verify the artifact-set assertion is exhaustive, the dedupe assertion uses real fingerprints (not just titles), and the LOW_COVERAGE assertion is reachable from the smoke fixture. Flag any code path the smoke does not exercise.

Acceptance: each reviewer returns a list of findings tagged `Important` / `Minor` / `Nit`.

- [ ] **Step 3: Address every Important finding**

Same `bug_NNN` naming used in Stage E (`bug_001 ...` etc.) so `git log --oneline` reads cleanly. Each fix is its own TDD-style commit.

- [ ] **Step 4: Re-run gates after fixes**

```bash
.venv/bin/pytest -q
.venv/bin/ruff check src/ tests/
```

Expected: still all green.

- [ ] **Step 5: Carry the Minor / Nit findings to the v0.2.1 sweep routine**

If any `Minor` or `Nit` findings turn up that don't block merge, add them to the existing v0.2.1 sweep routine (`trig_01X7svKoq56A5jkVkaLTdfKT`) by running `RemoteTrigger { action: "show", trigger_id: "..." }` to read its current punch list, then `RemoteTrigger { action: "update", ... }` to append. **Do NOT fix them on this branch** — they conflict with the pre-scheduled sweep PR.

---

## Task F.4.d: open the PR

- [ ] **Step 1: Push the branch**

```bash
git push -u origin phase-2/openclaw-eval-stage-f
```

- [ ] **Step 2: Open the PR**

```bash
gh pr create --title "Stage F: agentsec evaluate + scoring + report split" --body "$(cat <<'EOF'
## Summary

- New `agentsec evaluate --config openclaw-target.yaml --output ./report-…/` orchestrator: runs the remote suite + server-audit halves and writes the six spec §9.3 artifacts.
- New `agentsec.scoring` module — category aggregation, server-side fingerprint dedupe, coverage triple (denominator = `planned`), LOW_COVERAGE thresholds, combined-score reweighting, A–F grade ladder.
- New `OpenClawTargetConfig` Pydantic model for `openclaw-target.yaml` (spec §8.2).
- Split `reports/markdown.py` into three renderers (`remote`, `server-audit`, `combined`); added `reports/json_report.py` (findings.json + threat-intel-snapshot.yaml).
- Closed Stage C M4 carryover: `_UnreachableLLM` is gone; `NoOpJudge` is a proper `Judge` subclass.

**Audit findings closed:** OE-AUD-009 (scoring + low-coverage), OE-AUD2-011 (server-side fingerprint dedupe), OE-AUD3-006 (coverage denom).

## Test plan

- [x] `.venv/bin/pytest -q` — 416+N tests green
- [x] `.venv/bin/ruff check src/ tests/` — clean
- [x] `.venv/bin/python scripts/check_threat_refs.py` — green
- [x] `.venv/bin/python scripts/build_cve_db.py --check` — clean
- [x] `git grep -nE '/var/log/openclaw|~/.openclaw|/etc/systemd|/Library/' src/agentsec/audit/checks/` — zero
- [x] `git grep -n "_UnreachableLLM" src/ tests/` — zero
- [x] `tests/integration/test_evaluate_smoke.py` — six artifacts present, fingerprint dedupe verified, LOW_COVERAGE banner reachable
- [ ] Three-reviewer parallel pass on the diff — all Important findings addressed

## End-of-stage handoff to next session (Stage G)

Once Stage F merges:

- The next session should pick **Stage G** (parent plan §"Stage G", lines 2076–2092):
  - mock OpenClaw end-to-end test (`tests/integration/test_openclaw_mock.py`)
  - sample report directory committed at `docs/samples/report-2026-04-28/`
  - ROADMAP / CLAUDE.md / CHANGELOG / writing-test-cases.md / writing-adapters.md doc sync (OE-AUD-014)
- Stage G unlocks v0.2.0 release (`pyproject.toml` version bump + `CHANGELOG.md` final v0.2.0 entry).
- The v0.2.1 sweep routine (`trig_01X7svKoq56A5jkVkaLTdfKT`) is unaffected by Stage F — it self-fires 2026-05-12, regardless of whether Stage G has landed.
