It supports two execution modes: **auto** (fully programmatic, no LLM cost) and **assisted** (Claude steers mid-scan, adds follow-up tools, and analyzes results). + +### Key Design Decisions + +| Decision | Choice | Rationale | +|----------|--------|-----------| +| Surface model | Hybrid — CLI, web API, Claude skill share one engine | Follows existing RecipeRunner pattern; depth lives in the engine, each surface provides UX | +| Relationship to RecipeRunner | Sibling engines, shared infrastructure | Different concerns — scan-runner is a scan orchestrator, RecipeRunner is a generic step executor; forcing one to wrap the other would fight the abstraction | +| Tool selection | Auto-detect + named profiles + Claude analysis | Auto-detection covers common cases, profiles give repeatability, Claude adds intelligent steering | +| Execution model | Task graph (DAG) with reactive edges | Combines pipeline clarity with event-driven flexibility; DAG is auditable and visualizable | +| Engagement binding | Auto-create engagement, ephemeral option with importable output | Findings always have a home; ephemeral mode outputs structured JSON/SARIF for import later | +| Scan entity | First-class Scan model | Enables scan history, diffing, re-run, and audit trail | +| MCP execution | Built-in MCP client from day one | Uniform tool execution — auto mode gets full depth including CodeBadger, Arkana, GhydraMCP without Claude in the loop | + +--- + +## 1.

From: Emperiusm Date: Sun, 12 Apr 2026 03:10:01 -0400 Subject: [PATCH 14/64] =?UTF-8?q?fix(shared):=20run=5Fstreaming=20?= =?UTF-8?q?=E2=80=94=20watchdog=20pattern=20fixes=20cancel-task=20hang?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The original implementation placed the cancellation-wait task inside asyncio.wait(ALL_COMPLETED), causing the wait to block for the full timeout when a CancellationToken was provided but never triggered. Replace with a background watchdog coroutine that kills the process when cancellation fires, which unblocks the I/O reader tasks naturally. asyncio.wait now only tracks the two I/O tasks.

=?UTF-8?q?feat(scanner):=20ScanAPI=20=E2=80=94=20un?= =?UTF-8?q?ified=20scan=20entry=20point?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements plan(), execute(), pause(), resume(), cancel() as the unified public interface for scan orchestration; plan() creates a Scan record and calls ScanPlanner to produce the task DAG, lifecycle methods

Apr 2026 20:34:09 -0400 Subject: [PATCH 32/64] feat(scanner): parsers for gitleaks, nmap, trivy, generic JSON Adds GitleaksParser (JSON array, CWE-798 hardcoded), NmapParser (XML -oX, open ports only, HOST precision), TrivyParser (schema v2 Results array with CWE extraction), and GenericJsonParser (fallback for dict/list JSON with findings/results/vulnerabilities key detection).

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Build the full finding processing pipeline: parser protocol and router with builtin parsers (semgrep, gitleaks, nmap, trivy, generic JSON), normalization engine (paths, CWEs, severities, titles), multi-pass dedup engine, engagement-level cross-scan dedup, corroboration scoring, suppression engine, finding lifecycle with confidence decay, finding correlation and remediation grouping, scan diff (baseline comparison), and multi-format export (JSON, SARIF, CSV, Markdown). + +**Architecture:** Bottom-up — parser protocol and router first (takes raw bytes, yields `RawFinding`), then normalization (standardizes fields using data files from Plan 1), then dedup (strict fingerprint + fuzzy match), then higher-order pipeline stages (corroboration, suppression, lifecycle, correlation, remediation grouping), then scan diff, and finally export. Each stage is a standalone class with a simple interface: takes findings in, returns findings out. The full pipeline is assembled by the caller. Integration test at the end verifies the complete chain. + +**Tech Stack:** Python 3.12, Pydantic v2, asyncio, pytest + pytest-asyncio, `xml.etree.ElementTree` (nmap XML), `hashlib` (fingerprinting), `csv` (CSV export), `json` (JSON/SARIF export), `difflib` (fuzzy matching), `re` (title normalization) + +**Spec Reference:** `docs/superpowers/specs/2026-04-12-scan-runner-design.md` sections 5.1-5.12 + +**Decomposition Note:** Plan 4 of 5.

=?UTF-8?q?=20engine-to-pipeline=20wiring?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements ScanPipeline that assembles ParserRouter -> NormalizationEngine -> DedupEngine -> CorroborationScorer -> SuppressionEngine -> FindingLifecycle -> Store. Extends ScanEngine with optional pipeline param; completed task outputs are queued and processed asynchronously via _process_pipeline_results.
