+# N15 Selector Report Hardening Design
+
+日期：2026-07-09
+
+## 1. 背景
+
+N14 已在 `main` 上合并并推送，提供了离线 UIA selector 报告能力：
+
+- `internal/uiaselector/report.go`：报告模型、catalog report generator、JSON/Markdown renderer。
+- `cmd/uia-selector-report/main.go`：离线 CLI，只接受 dump 文件路径和输出报告路径。
+- `scripts/verify-n14-uia-selector-report.ps1`：运行测试、生成报告并做基础安全扫描。
+
+N14 最终 review 留下两个非阻塞建议：
+
+1. `StrictExitAmbiguous` 分支缺少显式单测。
+2. verifier 的输出安全检查仍以字符串扫描为主，并且运行 CLI 前没有清理旧输出文件。
+
+N15 的目标是把这些 review 建议收口为一个小型加固节点，不扩展产品能力，不接触 live UI，不新增 helper op，不新增 MCP tool，不扩展 live action surface。
+
+## 2. 目标
+
+N15 只做报告安全与验证加固：
+
+1. 增加 `StrictExitAmbiguous` 显式单测，锁定 `ambiguous_count > 0` 时严格模式返回 `3`。
+2. 加固 `scripts/verify-n14-uia-selector-report.ps1`，避免旧报告掩盖 CLI 输出回归。
+3. 增加输出文件检查：必须存在、必须是文件、大小必须大于 0。
+4. 增加 JSON 字段 allowlist 检查，确认 `selectors[].matches[]` 只包含允许的结构字段。
+5. 保持 N14 报告格式和 CLI 参数不变。
+
+## 3. 非目标
+
+N15 不做以下事项：
+
+```text
+新增 selector
+修改 selector catalog
+修改报告 JSON/Markdown 格式
+新增 CLI 参数
+新增 helper op
+新增 MCP tool
+连接内网 iSphere
+live dump 当前窗口
+使用 hwnd/process 参数
+点击控件
+输入文本
+打开会话
+搜索联系人
+发送消息
+发送文件
+接收文件
+读取聊天内容
+导出完整 visible text
+```
+
+N15 也不清理本地分支。分支清理可以在 N15 合并后单独执行。
+
+## 4. 推荐方案
+
+采用“小范围加固”方案，只修改两个文件：
+
+```text
+internal/uiaselector/report_test.go
+scripts/verify-n14-uia-selector-report.ps1
+```
+
+不修改：
+
+```text
+native/ISphereWinHelper/Program.cs
+internal/tools/winhelper.go
+cmd/isphere-mcp/main.go
+cmd/uia-selector-report/main.go
+internal/uiaselector/report.go
+```
+
+理由：N14 的实现逻辑已经通过最终验证和 review。N15 只需要补测试和 verifier 防回归能力，不需要改变生产代码路径。
+
+## 5. Ambiguous strict-mode 测试设计
+
+在 `internal/uiaselector/report_test.go` 中新增测试：
+
+```text
+TestStrictModeClassifiesAmbiguousMatches
+```
+
+测试构造一个最小 UIA tree：
+
+```text
+root Window frmMain
+  child Pane duplicate
+  child Pane duplicate
+```
+
+测试 catalog 只包含一个 read-only selector：
+
+```text
+id: duplicate_panel
+allowed_use: read_only_locate
+required:
+  automation_id: duplicate
+  control_type: Pane
+  framework_id: WinForm
+```
+
+期望：
+
+```text
+report.OK == true
+report.CatalogSize == 1
+report.MatchedCount == 1
+report.UnmatchedCount == 0
+report.AmbiguousCount == 1
+report.Selectors[0].MatchCount == 2
+StrictExitCode(report) == StrictExitAmbiguous
+```
+
+该测试只使用内存构造的 `Node`，不依赖 N12R fixture，也不涉及 visible text。
+
+## 6. Verifier 加固设计
+
+### 6.1 清理旧输出
+
+在 `go run ./cmd/uia-selector-report` 之前删除旧报告：
+
+```powershell
+Remove-Item -LiteralPath $jsonPath, $mdPath -Force -ErrorAction SilentlyContinue
+```
+
+目的：如果未来 CLI 回归为“退出 0 但未写新文件”，旧报告不会让后续存在性检查误通过。
+
+### 6.2 文件存在和非空检查
+
+替换当前 `Test-Path` 检查为更严格的文件检查：
+
+```powershell
+$jsonItem = Get-Item -LiteralPath $jsonPath -ErrorAction Stop
+if (-not $jsonItem.PSIsContainer -eq $false) { ... }
+if ($jsonItem.Length -le 0) { ... }
+```
+
+实际实现应避免 PowerShell 运算优先级歧义，推荐使用清晰表达：
+
+```powershell
+if ($jsonItem.PSIsContainer) { throw "JSON report path is not a file: $jsonPath" }
+if ($jsonItem.Length -le 0) { throw "JSON report is empty: $jsonPath" }
+```
+
+Markdown 报告同样检查。
+
+### 6.3 JSON match 字段 allowlist
+
+解析 JSON 后，对每个 `selectors[].matches[]` 对象检查字段集合，只允许：
+
+```text
+path
+control_type
+automation_id
+class_name
+framework_id
+has_name
+name_length
+```
+
+禁止出现：
+
+```text
+name
+value
+text
+visible_text
+```
+
+实现策略：
+
+1. 遍历 `$report.selectors`。
+2. 遍历 `$selector.matches`。
+3. 对每个 match 的 `$match.PSObject.Properties.Name` 做集合比较。
+4. 遇到不在 allowlist 中的字段立即失败。
+5. 如果字段名是 `name` 或 `value`，错误信息明确指出这是 visible text 字段泄漏。
+
+这比单纯扫描字符串更稳，因为它检查的是 JSON 对象结构。
+
+### 6.4 保留字符串扫描
+
+保留 N14 已有字符串扫描，用于发现：
+
+```text
+"name"
+"value"
+国网甘肃省电力公司
+send_after_approval
+send_file_after_approval
+receive_file_after_approval
+open_conversation
+InvokePattern
+ValuePattern.SetValue
+```
+
+字段 allowlist 和字符串扫描同时存在：
+
+- allowlist 负责结构化字段泄漏。
+- 字符串扫描负责已知敏感文本和动作词防线。
+
+## 7. 测试与验证策略
+
+N15 implementation plan 必须采用 TDD。
+
+最小验证命令：
+
+```powershell
+go test ./internal/uiaselector -run "TestStrictModeClassifiesAmbiguousMatches" -count=1
+powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-n14-uia-selector-report.ps1
+go test ./...
+```
+
+最终验证命令：
+
+```powershell
+go test ./internal/uiaselector ./cmd/uia-selector-report -count=1
+go test ./...
+powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-n14-uia-selector-report.ps1
+git diff --name-only main..HEAD -- native/ISphereWinHelper/Program.cs internal/tools/winhelper.go cmd/isphere-mcp/main.go
+```
+
+最后一条命令期望无输出。
+
+## 8. 风险与缓解
+
+### 风险 1：PowerShell 对单元素数组展开造成遍历差异
+
+缓解：实现遍历时使用 `@($report.selectors)` 和 `@($selector.matches)`，确保单元素和多元素都按数组处理。
+
+### 风险 2：allowlist 检查误报 PowerShell 内置属性
+
+缓解：只读取 `$match.PSObject.Properties.Name`，这返回 JSON 对象自身属性，不读取方法或扩展成员。
+
+### 风险 3：旧输出清理误删非目标文件
+
+缓解：只删除两个明确计算出的文件路径：
+
+```text
+runs/n14-selector-report/n12r-selector-report.json
+runs/n14-selector-report/n12r-selector-report.md
+```
+
+不递归删除目录。
+
+## 9. 验收条件
+
+N15 可接受条件：
+
+1. `StrictExitAmbiguous` 有显式单测。
+2. verifier 运行 CLI 前删除旧 JSON/Markdown 输出文件。
+3. verifier 检查 JSON/Markdown 输出存在、是文件、非空。
+4. verifier 对 JSON `matches[]` 执行字段 allowlist 检查。
+5. verifier 继续扫描 `"name"`、`"value"`、已知 visible text 和动作词。
+6. `go test ./...` 通过。
+7. `scripts\verify-n14-uia-selector-report.ps1` 通过。
+8. 不修改 helper/MCP/live action 文件。
+
+## 10. 推荐下一步
+
+下一步写 N15 implementation plan，拆分为两个小任务：
+
+1. TDD 增加 ambiguous strict-mode 单测。
+2. 加固 verifier 的旧输出清理、文件检查和 JSON 字段 allowlist。

+# N15 Selector Report Hardening Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Harden the N14 offline selector report tests and verifier so ambiguous strict-mode behavior and report-output safety regressions are caught before merge.
+
+**Architecture:** Keep N15 as a test/verifier-only change. Add an in-memory ambiguous-match test to `internal/uiaselector/report_test.go`, then strengthen `scripts/verify-n14-uia-selector-report.ps1` with stale-output cleanup, file/non-empty checks, and JSON match-field allowlist validation.
+
+**Tech Stack:** Go 1.23.x tests, existing `internal/uiaselector` package, Windows PowerShell 5.1-compatible verifier script, standard `go test` and repository Git workflow.
+
+---
+
+## Scope and boundary
+
+N15 changes only test and verifier coverage.
+
+Modify only:
+
+```text
+internal/uiaselector/report_test.go
+scripts/verify-n14-uia-selector-report.ps1
+```
+
+Do not modify:
+
+```text
+native/ISphereWinHelper/Program.cs
+internal/tools/winhelper.go
+cmd/isphere-mcp/main.go
+cmd/uia-selector-report/main.go
+internal/uiaselector/report.go
+internal/uiaselector/catalog.go
+internal/uiaselector/matcher.go
+```
+
+Do not add selectors, helper ops, MCP tools, CLI arguments, live hwnd/process handling, UI automation calls, clicks, keyboard input, clipboard operations, conversation actions, message sending, file transfer, or visible text export.
+
+## File structure
+
+```text
+internal/uiaselector/report_test.go
+  Add one explicit ambiguous strict-mode regression test using an in-memory UIA tree.
+
+scripts/verify-n14-uia-selector-report.ps1
+  Clean stale outputs before CLI execution, require fresh non-empty report files, and validate JSON match fields with an allowlist.
+```
+
+## Task 1: Cover ambiguous strict-mode classification
+
+**Files:**
+- Modify: `internal/uiaselector/report_test.go`
+
+- [ ] **Step 1: Add the ambiguous strict-mode regression test**
+
+Append this test to `internal/uiaselector/report_test.go`:
+
+```go
+func TestStrictModeClassifiesAmbiguousMatches(t *testing.T) {
+	root := &Node{
+		ControlType:  "Window",
+		AutomationID: "frmMain",
+		FrameworkID:  "WinForm",
+		Children: []Node{
+			{ControlType: "Pane", AutomationID: "duplicate", FrameworkID: "WinForm"},
+			{ControlType: "Pane", AutomationID: "duplicate", FrameworkID: "WinForm"},
+		},
+	}
+	catalog := []Selector{
+		{
+			ID:             "duplicate_panel",
+			Description:    "duplicate structural selector",
+			AllowedUse:     AllowedUseReadOnlyLocate,
+			Required:       Criteria{AutomationID: "duplicate", ControlType: "Pane", FrameworkID: "WinForm"},
+			StabilityScore: 80,
+			Evidence:       Evidence{CaptureID: "unit-test", UIAPath: "root/duplicate"},
+		},
+	}
+
+	report := RunCatalogReport("synthetic-ambiguous.json", root, catalog, fixedReportTime())
+	if !report.OK {
+		t.Fatalf("report OK=false: %#v", report.Error)
+	}
+	if report.CatalogSize != 1 {
+		t.Fatalf("catalog_size = %d, want 1", report.CatalogSize)
+	}
+	if report.MatchedCount != 1 {
+		t.Fatalf("matched_count = %d, want 1", report.MatchedCount)
+	}
+	if report.UnmatchedCount != 0 {
+		t.Fatalf("unmatched_count = %d, want 0", report.UnmatchedCount)
+	}
+	if report.AmbiguousCount != 1 {
+		t.Fatalf("ambiguous_count = %d, want 1", report.AmbiguousCount)
+	}
+	if len(report.Selectors) != 1 {
+		t.Fatalf("len(selectors) = %d, want 1", len(report.Selectors))
+	}
+	if got := report.Selectors[0].MatchCount; got != 2 {
+		t.Fatalf("selector match_count = %d, want 2", got)
+	}
+	if got := StrictExitCode(report); got != StrictExitAmbiguous {
+		t.Fatalf("StrictExitCode = %d, want %d", got, StrictExitAmbiguous)
+	}
+}
+```
+
+- [ ] **Step 2: Prove the test catches a broken ambiguous branch**
+
+Temporarily change `internal/uiaselector/report.go` in `StrictExitCode` from:
+
+```go
+	if report.AmbiguousCount > 0 {
+		return StrictExitAmbiguous
+	}
+```
+
+to:
+
+```go
+	if report.AmbiguousCount > 0 {
+		return StrictExitOK
+	}
+```
+
+Run:
+
+```powershell
+gofmt -w internal\uiaselector\report_test.go
+go test ./internal/uiaselector -run "TestStrictModeClassifiesAmbiguousMatches" -count=1
+```
+
+Expected: FAIL with:
+
+```text
+StrictExitCode = 0, want 3
+```
+
+Restore `internal/uiaselector/report.go` immediately after this command so production code again returns `StrictExitAmbiguous` for ambiguous reports. Do not commit the temporary mutation.
+
+- [ ] **Step 3: Run the ambiguous test with production code restored**
+
+Run:
+
+```powershell
+gofmt -w internal\uiaselector\report_test.go internal\uiaselector\report.go
+go test ./internal/uiaselector -run "TestStrictModeClassifiesAmbiguousMatches" -count=1
+```
+
+Expected: PASS.
+
+- [ ] **Step 4: Run package tests**
+
+Run:
+
+```powershell
+go test ./internal/uiaselector -count=1
+```
+
+Expected: PASS.
+
+- [ ] **Step 5: Commit ambiguous strict-mode test**
+
+Run:
+
+```powershell
+git add internal\uiaselector\report_test.go
+git diff --cached --name-only
+```
+
+Expected staged file list:
+
+```text
+internal/uiaselector/report_test.go
+```
+
+Then commit:
+
+```powershell
+git commit -m "test: cover N15 ambiguous strict exit"
+```
+
+## Task 2: Harden N14 selector report verifier
+
+**Files:**
+- Modify: `scripts/verify-n14-uia-selector-report.ps1`
+
+- [ ] **Step 1: Run a failing pre-change verifier hardening check**
+
+Run this PowerShell check before editing the verifier:
+
+```powershell
+$scriptPath = "scripts\verify-n14-uia-selector-report.ps1"
+$scriptText = Get-Content -LiteralPath $scriptPath -Raw -Encoding UTF8
+$requiredSnippets = @(
+    'Remove-Item -LiteralPath $jsonPath, $mdPath -Force -ErrorAction SilentlyContinue',
+    '$jsonItem = Get-Item -LiteralPath $jsonPath -ErrorAction Stop',
+    'if ($jsonItem.PSIsContainer)',
+    'if ($jsonItem.Length -le 0)',
+    '$mdItem = Get-Item -LiteralPath $mdPath -ErrorAction Stop',
+    '$allowedMatchFields = @(',
+    '$match.PSObject.Properties',
+    'JSON match leaks visible text field'

+foreach ($snippet in $requiredSnippets) {
+    if (-not $scriptText.Contains($snippet)) {
+        throw "missing verifier hardening snippet: $snippet"
+    }
+}
+```
+
+Expected: FAIL, with the first missing snippet indicating stale-output cleanup is not implemented yet.
+
+- [ ] **Step 2: Insert stale-output cleanup before CLI execution**
+
+In `scripts/verify-n14-uia-selector-report.ps1`, after:
+
+```powershell
+$jsonPath = Join-Path $outDir "n12r-selector-report.json"
+$mdPath = Join-Path $outDir "n12r-selector-report.md"
+```
+
+insert:
+
+```powershell
+Remove-Item -LiteralPath $jsonPath, $mdPath -Force -ErrorAction SilentlyContinue
+```
+
+- [ ] **Step 3: Replace output file existence checks with file and non-empty checks**
+
+Replace this block:
+
+```powershell
+if (-not (Test-Path -LiteralPath $jsonPath)) {
+    throw "JSON report was not created: $jsonPath"
+}
+if (-not (Test-Path -LiteralPath $mdPath)) {
+    throw "Markdown report was not created: $mdPath"
+}
+```
+
+with:

+    throw "Markdown report path is not a file: $mdPath"
+}
+if ($mdItem.Length -le 0) {
+    throw "Markdown report is empty: $mdPath"
+}
+```
+
+- [ ] **Step 4: Add JSON match-field allowlist validation after report summary checks**
+
+After this block:
+
+```powershell
+if ($report.ambiguous_count -ne 0) {
+    throw "ambiguous_count=$($report.ambiguous_count), want 0"
+}
+```
+
+insert:
+
+```powershell
+Write-Host "## JSON match field allowlist"
+$allowedMatchFields = @(
+    "path",
+    "control_type",
+    "automation_id",
+    "class_name",
+    "framework_id",
+    "has_name",
+    "name_length"
+)
+$allowedMatchFieldLookup = @{}
+foreach ($field in $allowedMatchFields) {
+    $allowedMatchFieldLookup[$field] = $true
+}
+foreach ($selector in @($report.selectors)) {
+    foreach ($match in @($selector.matches)) {
+        if ($null -eq $match) {
+            continue

+        foreach ($property in @($match.PSObject.Properties)) {
+            $fieldName = $property.Name
+            if ($fieldName -eq "name" -or $fieldName -eq "value") {
+                throw "JSON match leaks visible text field: $fieldName"
+            }
+            if (-not $allowedMatchFieldLookup.ContainsKey($fieldName)) {
+                throw "JSON match contains disallowed field: $fieldName"
+            }
+        }
+    }
+}
+```
+
+- [ ] **Step 5: Run the hardening check again**
+
+Run:
+
+```powershell
+$scriptPath = "scripts\verify-n14-uia-selector-report.ps1"
+$scriptText = Get-Content -LiteralPath $scriptPath -Raw -Encoding UTF8
+$requiredSnippets = @(
+    'Remove-Item -LiteralPath $jsonPath, $mdPath -Force -ErrorAction SilentlyContinue',
+    '$jsonItem = Get-Item -LiteralPath $jsonPath -ErrorAction Stop',

+    'if ($jsonItem.Length -le 0)',
+    '$mdItem = Get-Item -LiteralPath $mdPath -ErrorAction Stop',
+    '$allowedMatchFields = @(',
+    '$match.PSObject.Properties',
+    'JSON match leaks visible text field'
+)
+foreach ($snippet in $requiredSnippets) {
+    if (-not $scriptText.Contains($snippet)) {
+        throw "missing verifier hardening snippet: $snippet"
+    }
+}
+Write-Host "VERIFIER_HARDENING_SNIPPETS_OK"
+```
+
+Expected:
+
+```text
+VERIFIER_HARDENING_SNIPPETS_OK
+```
+
+- [ ] **Step 6: Run the hardened verifier**
+
+Run:
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-n14-uia-selector-report.ps1
+```
+
+Expected output includes:
+
+```text
+## go test ./internal/uiaselector ./cmd/uia-selector-report
+## go run ./cmd/uia-selector-report
+N14 selector report generated: catalog=10 matched=10 unmatched=0 ambiguous=0
+## JSON match field allowlist
+## output safety scan
+N14 UIA selector report verification passed.
+```
+
+- [ ] **Step 7: Commit verifier hardening**
+
+Run:
+
+```powershell
+git add scripts\verify-n14-uia-selector-report.ps1
+git diff --cached --name-only
+```
+
+Expected staged file list:
+
+```text
+scripts/verify-n14-uia-selector-report.ps1
+```
+
+Then commit:
+
+```powershell
+git commit -m "test: harden N15 selector report verifier"
+```
+
+## Task 3: Final verification and boundary check
+
+**Files:**
+- No new files.
+- Verify: `internal/uiaselector/report_test.go`, `scripts/verify-n14-uia-selector-report.ps1`, and unchanged helper/MCP action surface.
+
+- [ ] **Step 1: Run targeted tests**
+
+Run:
+
+```powershell
+go test ./internal/uiaselector -run "TestStrictModeClassifiesAmbiguousMatches" -count=1
+go test ./internal/uiaselector ./cmd/uia-selector-report -count=1
+```
+
+Expected: both commands PASS.
+
+- [ ] **Step 2: Run repository tests**
+
+Run:
+
+```powershell
+go test ./...
+```
+
+Expected: all packages PASS.
+
+If dependency download fails with a transient proxy error, retry once with:
+
+```powershell
+$env:GOPROXY = "https://goproxy.cn,direct"
+go test ./...
+```
+
+- [ ] **Step 3: Run the hardened verifier**
+
+Run:
+
+```powershell
+powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-n14-uia-selector-report.ps1
+```
+
+Expected: verifier PASS and output includes `## JSON match field allowlist`.
+
+- [ ] **Step 4: Check helper/MCP/live action boundary**
+
+Run:
+
+```powershell
+git diff --name-only main..HEAD -- native/ISphereWinHelper/Program.cs internal/tools/winhelper.go cmd/isphere-mcp/main.go cmd/uia-selector-report/main.go internal/uiaselector/report.go internal/uiaselector/catalog.go internal/uiaselector/matcher.go
+```
+
+Expected: no output.
+
+If any file appears, stop and inspect because N15 is test/verifier-only.
+
+- [ ] **Step 5: Check changed files**
+
+Run:
+
+```powershell
+git diff --name-only main..HEAD
+```
+
+Expected changed files are limited to:
+

+- [ ] **Step 6: Final status**
+
+Run:
+
+```powershell
+git status --short --branch
+git log --oneline --max-count=6
+```
+
+Expected: working tree clean on `codex/n15-report-hardening`. Do not push unless the user explicitly requests pushing this branch or merging to main.
+
+## Self-review checklist
+
+- Spec coverage: ambiguous strict-mode test, stale-output cleanup, file/non-empty checks, JSON match-field allowlist, retained forbidden string scan, and helper/MCP boundary check are all covered.
+- Scope: only `internal/uiaselector/report_test.go` and `scripts/verify-n14-uia-selector-report.ps1` are implementation targets; design and plan docs are documentation targets.
+- Boundary: no helper op, no MCP tool, no live hwnd/process behavior, no UI action, no report format change, no CLI argument change.
+- Verification: final commands include targeted tests, all repository tests, hardened verifier, boundary diff check, and changed-file check.
+- Commit cadence: test and verifier hardening are separate commits.
