# Router-gate v4 — Stream C (Static content scan + MCP path-deny) 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:** Build five pure, dependency-injected scanner/classifier modules that the router-gate hooks consume to (a) statically scan multi-language test/boot files for code-execution payloads, (b) post-filter `Glob` results that touch `~/.claude/runtime/`, (c) classify MCP tool calls against a path-deny / URL-whitelist / SQL-statement overlay, and (d) scan commit messages for exfiltration payloads.

**Architecture:** Every module is a **pure library** — no `process.stdin`, no hook wiring, no `child_process`. File reads, glob expansion, path normalization, and LLM-judge calls are **injected as functions** (the codebase's established `decide({...})` pattern, e.g. `tools/enforce-semgrep-security.mjs`). Stream A's `pathNormalize`/`isProtectedPath` and Stream D's `llmJudgeCall` are NOT created here — they arrive as injected params with safe local **stubs** as defaults. This keeps Stream C's file scope disjoint from A/B/D/E/G (zero merge conflicts) and every function unit-testable in isolation. The consuming hooks (`enforce-router-gate.mjs` in Stream B, registration in Stream G) import these modules and supply the real I/O.

**Tech Stack:** Node.js ES modules (`.mjs`), vitest. No new npm dependencies — `glob` expansion is the consumer's job (we filter an already-expanded array), so the missing `glob` package is irrelevant to Stream C.

## File Structure

All files live in `tools/` (repo root, NOT `app/`). Tests sit beside each module per project convention (`tools/<name>.test.mjs`). The vitest tools config (`app/vitest.config.tools.mjs`) auto-includes `../tools/*.test.mjs`.

| File | Responsibility |
|---|---|
| `tools/static-content-scanner.mjs` | `TEST_RUNNERS`, `isTestRunner`, `detectLanguage`, `scanContent` (PHP/Ruby/Go/Java/Rust/.NET suspicious patterns), `scanFileWith` (injected reader). Owns the test-runner regex shared with framework-boot. |
| `tools/static-content-scanner.test.mjs` | Unit tests for the above. |
| `tools/framework-boot-scanner.mjs` | F7 — `detectProjectType` (injected `fileExists`), `bootPathSet`, `matchesBootPattern`, `intersectEditedBootFiles`, `extractPhpMethodBody` (model `boot()` scan), `decideBootScan`. Imports `isTestRunner` + `scanContent` from static-content-scanner. |
| `tools/framework-boot-scanner.test.mjs` | Unit tests. |
| `tools/glob-restricted-filter.mjs` | F8 — `globNeedsFilter(pattern)`, `filterRestrictedMatches(matches, deps)`. Pure: filters an already-expanded path array; no `glob` import. |
| `tools/glob-restricted-filter.test.mjs` | Unit tests. |
| `tools/mcp-tool-classifier.mjs` | §5.3 + G1 + G12 — `DEFAULT_MCP_CLASSIFICATION` (frozen), `matchClassificationKey` (glob→regex, most-specific wins), `classifyMcpTool` (read_only / hard_blacklist / conditional with `path_args`, `query_prefix_scan`, `query_full_statement_scan`, `url_whitelist`, WebSearch llm-judge flag). |
| `tools/mcp-tool-classifier.test.mjs` | Unit tests. |
| `tools/commit-message-scanner.mjs` | G11 — `SUSPICIOUS_MESSAGE_PATTERNS`, `scanCommitMessagePatterns` (sync regex), `scanCommitMessage` (async, injected `llmJudge`, default stub). |
| `tools/commit-message-scanner.test.mjs` | Unit tests. |

**Stub contract (defaults baked into each module, overridden by consumers/tests):**

| Injected dep | Provider stream | Stream C default stub |
|---|---|---|
| `normalize(target)` | A (`path-normalization.mjs`) | local `defaultNormalize` — backslash→slash + `.toLowerCase()` |
| `isProtectedPath(normalized)` | A / B (gate path-deny list) | `defaultIsProtectedPath` → `false` (tests inject a real predicate) |
| `isProtectedInode(path)` | A (`protectedInodes` Set) | `() => false` |
| `readFile(path)` | consumer hook (`fs.readFileSync`) | required arg — no default (caught by try/catch) |
| `fileExists(relPath)` | consumer hook (`fs.existsSync`) | required arg |
| `llmJudge({model, prompt})` | D (`llm-judge.mjs`) | `defaultLlmJudgeStub` → `{ verdict: 'NO', stub: true }` |

---

## Conventions (match existing `tools/*.mjs`)

- Pure functions take a single options object and `export` named for testing (see `tools/enforce-semgrep-security.mjs:68` `decide({...})`).
- Tests: `import { describe, it, expect } from 'vitest';` then `import { ... } from './<module>.mjs';`.
- **No catastrophic backtracking.** The project had a redos incident (`tools/adr-judge.py`, CLAUDE.md v2.31). Forbidden: nested quantifiers like `(?:.*?\n)*?`, unbounded `[\s\S]*` followed by a quantified group. For dynamic-dispatch co-occurrence (e.g. Go `reflect.ValueOf` … `.Call(`), use **two independent anchored regexes both tested against the source** (`all: [reA, reB]`), never one proximity regex.
- Brace/body extraction (PHP `boot()`) uses a **character-scan brace matcher**, not regex.
- Run a single test file during TDD (PowerShell, from repo root):
  `cd app; npx vitest run --config vitest.config.tools.mjs ../tools/<name>.test.mjs`
- Run the whole tools suite: `npm run test:tools` (from repo root).

## Task 9: Stream-wide verification + push

**Files:** none (verification + git).

- [ ] **Step 1: Run the full tools suite**

Run (from repo root): `npm run test:tools`
Expected: GREEN — all pre-existing tests PLUS the new Stream C tests (~90+ added across 5 modules). Note the exact `tests passed / tests total` line for the sentinel.

- [ ] **Step 2: Cross-module sanity check**

Confirm `framework-boot-scanner.mjs` correctly imports from `static-content-scanner.mjs` (no circular import, no duplicate `TEST_RUNNERS`). Verify with:

Run: `cd app; npx vitest run --config vitest.config.tools.mjs ../tools/static-content-scanner.test.mjs ../tools/framework-boot-scanner.test.mjs ../tools/glob-restricted-filter.test.mjs ../tools/mcp-tool-classifier.test.mjs ../tools/commit-message-scanner.test.mjs`
Expected: 5 files, all PASS.

- [ ] **Step 3: Self-review against spec (run the checklist below, fix inline)**

Re-read §5.2 / §5.3 / G1 / G11 / G12 and confirm each is covered (see Self-Review section). Fix any gap inline (new failing test → code → green → commit) before pushing.

- [ ] **Step 4: Write the verification sentinel (required by `enforce-verify-before-push`)**

The push gate (`tools/enforce-verify-before-push.mjs`) blocks `git push` unless a fresh (`< 30 min`) `verify-pass-<session>.json` sentinel with `result: "pass"` exists. Because this change is code (not docs-only), the sentinel is mandatory. Write it from the GREEN `npm run test:tools` run per the recipe in memory `feedback_vitest_sentinel_recipe.md` (sentinel path `~/.claude/runtime/verify-pass-<session-id>.json`, fields: `result`, `exit_code`, `tests_passed`, `tests_total`, `tests_failed`, `ts`).

If the sentinel mechanism is unavailable in this session, the fallback is a global override phrase in the push prompt: **`срочно`** or **`ремонт инфраструктуры`** (the latter requires a one-line justification on the next line).

- [ ] **Step 5: Push the branch**

```bash
git push origin feat/v4-stream-C
```

Expected: branch `feat/v4-stream-C` published to origin. Confirm with `git log origin/feat/v4-stream-C --oneline -1`.

- [ ] **Step 6: Update the session log**

Append to `docs/sessions/CURRENT.md` (Pravila §15.2) the Stream C entry status → `review` (ready for Checkpoint 1 merge by the master session).

## Self-Review

**1. Spec coverage** — each requirement maps to a task:

| Spec item | Task |
|---|---|
| §5.2 `TEST_RUNNERS` + test-runner detection | Task 1 (`isTestRunner`) |
| §5.2 language detection | Task 1 (`detectLanguage`) |
| §5.2 PHP/Ruby/Go/Java/Rust/.NET suspicious patterns | Task 2 (`scanContent`) |
| §5.2 protected-sensitive (delete/write "if protected") | Task 2 (`protected_sensitive` category) |
| §5.2 F7 project-type detection | Task 3 (`detectProjectType`) |
| §5.2 F7 boot-path file sets (Laravel/Rails/Express/Django/Spring) | Task 3 (`bootPathSet`) |
| §5.2 F7 edited-files intersection → hard-block | Task 4 (`decideBootScan`, `intersectEditedBootFiles`) |
| §5.2 F7 model `boot()`-only scan | Task 4 (`extractPhpMethodBody` + `BOOT_BODY_ONLY`) |
| §5.2 F8 Glob post-execution filter (runtime/ + `/restricted/` + protectedInodes) | Task 5 (`globNeedsFilter`, `filterRestrictedMatches`) |
| §5.3 classification map + read_only/hard_blacklist/conditional/default | Task 6 + 7 |
| §5.3 `path_args` protected check | Task 7 |
| §5.3 `query_prefix_scan` (browser/db prefix) | Task 7 |
| §5.3 URL whitelist (browser_navigate) | Task 7 |
| §5.3 unknown MCP tool → default block | Task 7 |
| G1 WebSearch/WebFetch classification + URL whitelist + content-scan flag | Task 6 (map) + Task 7 (logic) |
| G11 commit message content scan + LLM-judge | Task 8 |
| G12 database-query full-statement scan | Task 6 (map) + Task 7 (`query_full_statement_scan`) |

**Gaps acknowledged (out of Stream C scope, by design):**
- Real `pathNormalize` / `isProtectedPath` → Stream A (injected; default stub here).
- Real `llmJudgeCall` → Stream D (injected; NO-stub here).
- WebFetch **fetched-content** post-execution scan (the actual content erase + AskUser) → consumer hook (Stream B/G); Stream C only emits the `needsContentScan` flag.
- Actual glob expansion (`glob.sync`) → consumer hook (Stream B/G); Stream C filters the expanded array.
- Hook wiring / `.claude/settings.json` registration → Stream G.

**2. Placeholder scan** — no "TODO", "implement later", or "similar to Task N". Every code step contains complete source. Every test step contains real `it()` assertions.

**3. Type consistency** — names verified across tasks:
- `scanContent(source, lang, opts)` defined Task 2, consumed in `decideBootScan` Task 4 and `scanFileWith` Task 2. ✔
- `isTestRunner` defined Task 1, consumed in `decideBootScan` Task 4. ✔
- `detectLanguage` defined Task 1, consumed in `scanFileWith` (Task 2) + `decideBootScan` (Task 4). ✔
- `matchesBootPattern` / `bootPathSet` defined Task 3, consumed in `intersectEditedBootFiles` Task 4. ✔
- `matchClassificationKey` defined Task 6, consumed in `classifyMcpTool` Task 7. ✔
- `DEFAULT_MCP_CLASSIFICATION` defined Task 6, default in `classifyMcpTool` Task 7. ✔
- `scanCommitMessagePatterns` defined + consumed within Task 8; `defaultLlmJudgeStub` consistent. ✔
- Finding shape `{ name, category, lang }` (Task 2) → `decideBootScan` spreads `{ ...fnd, file }` (Task 4). ✔
- Decision shape `{ decision: 'allow'|'block'|'ask', ... }` consistent across `classifyMcpTool`. ✔

## Execution Handoff

**Plan complete and saved to `docs/superpowers/plans/2026-05-29-router-gate-v4-stream-C-static-mcp.md`. Two execution options:**

**1. Subagent-Driven (recommended)** — I dispatch a fresh subagent per task, review between tasks, fast iteration. (Project wrapper: `subagent-driven-development` skill with the git-safety verify-protocol per Pravila §15.1.)

**2. Inline Execution** — Execute tasks in this session using executing-plans, batch execution with checkpoints.

**Which approach?**
