Each run writes one +Markdown report per vulnerability under `strix_runs//vulnerabilities/*.md`. +This system turns those reports into **per-finding GitHub issues** in the +`ContextualWisdomLab/appguardrail` tracker, deduplicated and lifecycle-managed +so the tracker always reflects the current state of each repository's findings. + +It **replaces** the previous approach, where `appguardrail` polled failed runs +and opened one coarse issue per failed run with no close-on-fix. That collector +also never worked because its GitHub App identity was never provisioned. + +## Components + +| File | Role | +| ---- | ---- | +| `scripts/ci/strix_emit_appguardrail_issues.py` | Parses reports, plans and applies issue operations. Pure parsing/planning + a thin `gh api` client. | +| `tests/test_strix_emit_appguardrail_issues.py` | Unit tests: parsing, dedup hashing, op planning, close-on-fix set difference, incomplete-scan guard, dry-run and live execution. | +| `.github/workflows/strix.yml` (final steps) | Runs the emitter after the scan/gate with a repository-scoped Noema App token. Missing credentials or failed issue reads/writes fail visibly. | + +## How it works + +### Parsing + +Each `vulnerabilities/*.md` report is parsed into a normalized `Finding`: +`title`, `severity` (CRITICAL/HIGH/MEDIUM/LOW/NONE), `cvss` + vector, `target`, +`endpoint`, `method`, `model`, `code_location` (`path:line[-range]`), +`description`, `impact`, `remediation`. Field lines tolerate plain +(`Severity: HIGH`) and Markdown-bold (`- **Severity:** HIGH`) styles, and code +locations are recovered from a `Code Locations` section, a labelled line, or a +prose reference. `/workspace//` and PR-scope sandbox prefixes are stripped +so a file hashes identically across runs. + +### Deduplication + +The stable identity of a finding is: + +``` +dedup_key = sha256(source_repo + "\n" + finding_title + "\n" + normalized_code_location) +``` + +Titles are whitespace-collapsed. The full hash is stored in a hidden issue-body +marker ``. Existing issues (open **or** closed) are +looked up by this hash before anything is created. Because the location is part +of the key, a finding that moves to a different line is a **new identity**: the +new location gets a fresh issue and the stale one is closed on fix. + +### Issue shape + +- **Title**: `[strix] : (<path>:<line>)` +- **Labels**: `strix`, `security`, `repo:<name>`, `severity:<level>` +- **Body**: full finding details, source repo/PR/head/run links, and three + hidden markers (`strix-finding`, `strix-severity`, `strix-location`) that drive + reconciliation. + +The full finding identity is kept in the hidden body marker instead of creating +one repository label per finding; this prevents unbounded label growth as the +organization-wide tracker accumulates findings. + +### Lifecycle + +| Situation | Action | +| --------- | ------ | +| Finding has no existing issue | **Create** an issue. | +| Finding matches an open issue | **Update** the body (refresh run/head/PR, CVSS, remediation). **Comment** only if severity changed. | +| Finding matches a closed issue | **Reopen** (update to `state: open`) and refresh. | +| Open issue's finding absent from a **complete** scan | **Close** with a `Resolved on <head_sha>` comment. | + +### Close-on-fix guard + +Close-on-fix runs **only when the scan completed cleanly**. In the workflow this +is gated on the explicit `steps.run_strix.outputs.scan_complete == 'true'` +signal, and only a whole-repository `push`, `schedule`, or non-PR manual scan +uses `--scope full`. A provider-neutral skip deliberately exits the required +step successfully but keeps `scan_complete=false`; a failed or incomplete scan +does the same. Those runs may create/update findings already present in their +reports, but **never close** an issue. PR scans always use `--scope pr` and never +close issues because absence from changed files is not proof of resolution. The +emitter defaults both guards to their safe values. + +### Authentication and DRY-RUN + +The emitter needs **Issues: write** on `appguardrail`; a required workflow's +ordinary `github.token` cannot write cross-repository issues. The workflow uses +the existing organization-owned **cwl-noema-review** GitHub App and mints an +installation token with `actions/create-github-app-token`, explicitly scoped to +the single `appguardrail` repository and `permission-issues: write`. The App +client ID and private key remain in the existing +`NOEMA_GITHUB_APP_CLIENT_ID` organization variable and +`NOEMA_GITHUB_APP_PRIVATE_KEY` organization secret. The short-lived token is +passed only as `STRIX_ISSUE_APP_TOKEN` and token-like output is redacted. + +This path is intentionally fail-closed. Missing credentials, token-mint +failure, issue-list failure, label bootstrap failure, and every rejected issue +mutation produce `::error::` output and a nonzero step result. There is no +implicit live-run fallback to dry-run, so a green workflow cannot silently lose +findings. `--dry-run` remains an explicit local/test-only mode. + +## One-time enablement + +The existing Noema App and organization credentials are reused. Complete these +permission checks once before merging the workflow change: + +1. **Grant cwl-noema-review `Issues: Read and write`.** + `github.com/organizations/ContextualWisdomLab/settings/apps` → open the + **cwl-noema-review** app → **Permissions & events** → **Repository + permissions** → set **Issues** to **Read and write** → **Save changes**. +2. **Ensure the App is installed on `appguardrail`.** + `github.com/organizations/ContextualWisdomLab/settings/installations` → open + the **cwl-noema-review** installation → **Repository access** → confirm + **appguardrail** is included → **Save**. Accept the pending permission change + on the installation if GitHub requests it. + +Until both hold, collection fails visibly with the exact configuration or API +reason in the run log. The next scan after the permission is accepted emits and +reconciles issues without another code deployment. + +## Retiring the old collector (do this after this lands) + +The previous per-failed-run collector in **`ContextualWisdomLab/appguardrail`**, +`.github/workflows/org-security-failure-collector.yml`, must be **disabled or +removed** once this source-side emitter is live, otherwise the two systems will +file duplicate/overlapping issues. That change lives in the `appguardrail` repo +and cannot be made from this repository — remove the workflow (or set it to +`workflow_dispatch`-only / delete it) as a follow-up PR there. The +`ORG_SECURITY_FAILURE_APP_ID` / `ORG_SECURITY_FAILURE_APP_PRIVATE_KEY` secrets it +depended on can also be retired. diff --git a/scripts/ci/strix_emit_appguardrail_issues.py b/scripts/ci/strix_emit_appguardrail_issues.py new file mode 100644 index 00000000..c2a35a0b --- /dev/null +++ b/scripts/ci/strix_emit_appguardrail_issues.py @@ -0,0 +1,1159 @@ +#!/usr/bin/env python3 +"""Emit per-finding Strix security issues into the appguardrail tracker. + +The central Strix workflow (``.github/workflows/strix.yml``) writes one Markdown +report per vulnerability under ``strix_runs/<run>/vulnerabilities/*.md``.
