+# Sprint 20260403-001 — Integration E2E Coverage Gaps
+
+## Topic & Scope
+
+Close the remaining integration e2e test coverage gaps:
+- Add GitHubApp connector e2e tests (the only production provider without dedicated tests)
+- Build advisory source aggregation pipeline tests (initial sync, incremental, merge, dedup)
+- Add Rekor transparency log e2e tests (submit, verify, proof chain)
+- Document eBPF Agent test limitations (mock-only in CI, real kernel requires Linux host)
+
+Working directory: `src/Web/StellaOps.Web/tests/e2e/integrations/` (Playwright tests)
+Supporting directories:
+- `devops/compose/fixtures/integration-fixtures/advisory/` (fixture data)
+- `devops/compose/` (compose files for Rekor fixture)
+
+Expected evidence: All new tests passing in `npx playwright test --config=playwright.integrations.config.ts`
+
+## Dependencies & Concurrency
+
+- Requires main Stella Ops stack + integration fixtures running
+- Rekor tests require `--profile sigstore-local` (rekor-v2 container)
+- Advisory aggregation tests require fixture data files (KEV JSON, GHSA stubs)
+- Tasks 1-4 can run in parallel (no interdependencies)
+
+## Documentation Prerequisites
+
+- `src/Integrations/__Plugins/StellaOps.Integrations.Plugin.GitHubApp/` — plugin API
+- `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Kev/` — KEV pipeline
+- `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Ghsa/` — GHSA pipeline
+- `src/Concelier/__Libraries/StellaOps.Concelier.Core/Canonical/` — merge strategy
+- `src/Attestor/StellaOps.Attestor.Core/Rekor/` — Rekor interfaces

+
+## Delivery Tracker
+
+### TASK-1 — GitHubApp Connector E2E Tests
+Status: DONE
+Dependency: none
+Owners: Developer
+
+**Context:** GitHubApp (provider=200, type=SCM) has a plugin and nginx fixture (`stellaops-github-app-fixture` at `127.1.1.7`) but no dedicated e2e test file. The fixture mocks:
+- `GET /api/v3/app` → `{"id":424242,"name":"Stella QA GitHub App","slug":"stella-qa-app"}`
+- `GET /api/v3/rate_limit` → `{"resources":{"core":{"limit":5000,"remaining":4991,"reset":...}}}`
+
+**Create file:** `tests/e2e/integrations/github-app-integration.e2e.spec.ts`
+
+Tests to add:
+1. **Compose Health** — verify `stellaops-github-app-fixture` container is healthy
+2. **Direct Probe** — `GET http://127.1.1.7/api/v3/app` returns 200 with `Stella QA`
+3. **Connector Lifecycle** — full CRUD:
+   - POST create integration (type=2, provider=200, endpoint=github-app-fixture.stella-ops.local)
+   - POST test-connection → success, response includes appName/appId
+   - GET health-check → Healthy with rate limit details
+   - GET by ID → verify fields
+   - PUT update → change name, verify
+   - DELETE → verify 404 on subsequent GET
+4. **List in SCM tab** — verify integration appears in `/setup/integrations/scm` UI table
+5. **Cleanup** — afterAll deletes created integrations
+
+**Add to helpers.ts:**
+```typescript
+githubApp: {
+  name: 'E2E GitHub App',
+  type: 2,              // Scm
+  provider: 200,        // GitHubApp
+  endpoint: 'http://github-app-fixture.stella-ops.local',
+  authRefUri: null,
+  organizationId: 'e2e-github-test',
+  extendedConfig: { scheduleType: 'manual' },
+  tags: ['e2e'],
+}
+```
+
+Completion criteria:
+- [ ] `github-app-integration.e2e.spec.ts` exists with 8+ tests
+- [ ] `githubApp` config added to `helpers.ts` INTEGRATION_CONFIGS
+- [ ] All tests pass in full suite run
+- [ ] GitHubApp appears in SCM tab UI test
+
+---
+
+### TASK-2 — Advisory Source Aggregation Pipeline Tests
+Status: DONE
+Dependency: none
+Owners: Developer
+
+**Context:** The advisory fixture (`stellaops-advisory-fixture` at `127.1.1.8`) only returns health checks — no real advisory data. The "passed" aggregation smoke tests verify API shape, not pipeline execution. The fetch→parse→map pipeline is completely untested end-to-end.
+
+**Problem:** Real advisory sources (cisa.gov, api.first.org, github.com) are external — can't depend on them in CI. Need deterministic fixture data.
+
+#### Sub-task 2a — Seed Advisory Fixture with Real Data
+
+**Create fixture data files:**
+
+1. `devops/compose/fixtures/integration-fixtures/advisory/data/kev-catalog.json`
+   - Minimal KEV catalog with 5 CVEs (realistic structure, fake IDs)
+   - Fields: cveID, vendorProject, product, vulnerabilityName, dateAdded, shortDescription
+   - Include one CVE that overlaps with GHSA fixture (for merge testing)
+
+2. `devops/compose/fixtures/integration-fixtures/advisory/data/ghsa-list.json`
+   - 3 GHSA advisories in REST API format
+   - Include CVE aliases, severity, CVSS, affected packages
+   - One CVE overlaps with KEV fixture (CVE-2024-0001)
+
+3. `devops/compose/fixtures/integration-fixtures/advisory/data/epss-scores.csv`
+   - 10 EPSS rows (header + data): cve,epss,percentile
+   - Include CVEs from KEV and GHSA fixtures for join testing
+
+**Update nginx config** (`advisory/default.conf`):
+```nginx
+location = /kev/known_exploited_vulnerabilities.json {
+    alias /etc/nginx/data/kev-catalog.json;
+    add_header Content-Type "application/json";
+}
+location ~ ^/ghsa/security/advisories$ {
+    alias /etc/nginx/data/ghsa-list.json;
+    add_header Content-Type "application/json";
+}
+location = /epss/epss_scores-current.csv {
+    alias /etc/nginx/data/epss-scores.csv;
+    add_header Content-Type "text/csv";
+}
+```
+
+**Update docker-compose** to mount data directory into advisory-fixture.
+
+#### Sub-task 2b — Initial Sync Tests
+
+**Create file:** `tests/e2e/integrations/advisory-pipeline.e2e.spec.ts`
+
+Gate behind `E2E_ADVISORY_PIPELINE=1` (these tests trigger real sync jobs and take longer).
+
+**Test: Initial full sync (KEV)**
+1. Pre-check: GET `/api/v1/advisory-sources/kev/freshness` — note initial totalAdvisories
+2. Ensure KEV source is enabled: POST `/api/v1/advisory-sources/kev/enable`
+3. Trigger sync: POST `/api/v1/advisory-sources/kev/sync`
+4. Poll freshness endpoint every 5s for up to 120s until `totalAdvisories >= 5`
+5. Verify: `lastSuccessAt` is recent (< 5 minutes ago)
+6. Verify: `errorCount` did not increase
+7. Verify: GET `/api/v1/advisory-sources/summary` shows KEV as healthy
+
+**Test: Initial full sync (GHSA)**
+- Same pattern as KEV but for GHSA source
+- Verify totalAdvisories >= 3 after sync
+
+**Test: EPSS enrichment sync**
+- Trigger EPSS sync
+- Verify: EPSS observations exist (GET `/api/v1/scores/distribution` has data)
+- Verify: Advisory count did NOT increase (EPSS = metadata, not advisories)
+
+#### Sub-task 2c — Incremental Sync Tests
+
+**Test: Incremental KEV sync detects no changes**
+1. Sync KEV (initial — fixture returns 5 CVEs)
+2. Note totalAdvisories count
+3. Sync KEV again (same fixture data, no changes)
+4. Verify: totalAdvisories count unchanged
+5. Verify: `lastSuccessAt` updated (sync ran) but no new records
+
+**Test: Incremental KEV sync with new entries**
+- This requires the fixture to support a "v2" endpoint with more CVEs
+- Alternative: Use API to check that after initial sync, re-triggering doesn't create duplicates
+- Simpler approach: Verify `errorCount` doesn't increase on re-sync
+
+#### Sub-task 2d — Cross-Source Merge Tests
+
+**Test: Same CVE from KEV and GHSA creates canonical with 2 source edges**
+1. Fixture has CVE-2024-0001 in both KEV and GHSA data
+2. Sync KEV, then sync GHSA
+3. Query canonical: GET `/api/v1/canonical?cve=CVE-2024-0001`
+4. Verify: 1 canonical advisory returned
+5. Verify: `sourceEdges` array has entries from both "kev" and "ghsa"
+6. Verify: severity comes from GHSA (higher precedence than KEV null)
+
+**Test: Duplicate suppression — same source re-sync**
+1. Sync GHSA
+2. Note canonical count
+3. Re-sync GHSA (same data)
+4. Verify: canonical count unchanged
+5. Verify: no duplicate source edges
+
+#### Sub-task 2e — Query API Verification
+
+**Test: Paginated canonical query**
+- GET `/api/v1/canonical?offset=0&limit=2` → verify 2 items, has totalCount
+
+**Test: CVE-based query**
+- GET `/api/v1/canonical?cve=CVE-2024-0001` → verify match found
+
+**Test: Canonical by ID with source edges**
+- Get an ID from the paginated query
+- GET `/api/v1/canonical/{id}` → verify `sourceEdges`, `severity`, `affectedPackages`
+
+**Test: Score distribution**
+- GET `/api/v1/scores/distribution` → verify structure after EPSS sync
+
+Completion criteria:
+- [ ] Fixture data files created (kev-catalog.json, ghsa-list.json, epss-scores.csv)
+- [ ] Nginx config updated to serve fixture data
+- [ ] `advisory-pipeline.e2e.spec.ts` exists with 10+ tests
+- [ ] Initial sync verified for KEV, GHSA, EPSS
+- [ ] Cross-source merge verified (same CVE from 2 sources)
+- [ ] Duplicate suppression verified
+- [ ] Canonical query API verified
+- [ ] All tests pass when gated with E2E_ADVISORY_PIPELINE=1

+### TASK-3 — Rekor Transparency Log E2E Tests
+Status: DONE
+Dependency: none
+Owners: Developer
+
+**Context:** Rekor is deeply integrated as built-in infrastructure (not an Integrations plugin). It has:
+- `IRekorClient` with Submit, GetProof, VerifyInclusion
+- Docker fixture: `rekor-v2` container at `127.1.1.4:3322` (under `sigstore-local` profile)
+- API endpoints: POST `/api/v1/rekor/entries`, GET `/api/v1/rekor/entries/{uuid}`, POST `/api/v1/rekor/verify`
+- Healthcheck: `curl http://localhost:3322/api/v1/log`
+
+**Prerequisites:** Must start compose with `--profile sigstore-local`.
+
+**Create file:** `tests/e2e/integrations/rekor-transparency.e2e.spec.ts`
+
+Gate behind `E2E_REKOR=1` (requires sigstore-local profile).
+
+**Tests:**
+
+1. **Compose Health** — verify `stellaops-rekor` container is healthy
+2. **Direct Probe** — GET `http://127.1.1.4:3322/api/v1/log` returns 200 with tree state
+3. **Submit Entry** — POST `/api/v1/rekor/entries` with test attestation payload
+   - Verify: 201 response with uuid, logIndex
+4. **Get Entry** — GET `/api/v1/rekor/entries/{uuid}` returns entry details
+   - Verify: contains integratedTime, body, attestation data
+5. **Verify Inclusion** — POST `/api/v1/rekor/verify` with the submitted entry
+   - Verify: inclusion proof is valid
+6. **Log Consistency** — submit 2 entries, verify tree size increased
+7. **UI Evidence Check** — navigate to evidence/attestation page, verify Rekor proof references render
+
+Completion criteria:
+- [ ] `rekor-transparency.e2e.spec.ts` exists with 6+ tests
+- [ ] Tests gated behind E2E_REKOR=1
+- [ ] All tests pass when rekor-v2 container is running
+- [ ] Submit → Get → Verify full round-trip proven

+
+### TASK-4 — eBPF Agent Test Documentation and Hardening
+Status: DONE
+Dependency: none
+Owners: Developer
+
+**Context:** The eBPF Agent integration is tested against an nginx mock (`runtime-host-fixture` at `127.1.1.9`). It returns hardcoded JSON:
+- `/api/v1/health` → `{status:"healthy", probes_loaded:12, events_per_second:450}`
+- `/api/v1/info` → `{agent_type:"ebpf", probes:["syscall_open","syscall_exec",...]}`
+
+Tests verify API CRUD, not actual eBPF kernel tracing. This is correct for CI (no Linux kernel available in CI runner or Windows dev machine).
+
+**Tasks:**
+
+1. **Add edge case tests to existing `runtime-hosts.e2e.spec.ts`:**
+   - Create with invalid endpoint → test-connection fails gracefully
+   - Health-check on degraded agent (requires new fixture endpoint or 503 response)
+   - Multiple eBPF integrations can coexist (create 2, verify both in list)
+
+2. **Add fixture endpoint for degraded state:**
+   Update `runtime-host/default.conf` to add:
+   ```nginx
+   location = /api/v1/health-degraded {
+       return 200 '{"status":"degraded","agent":"ebpf","probes_loaded":3,"events_per_second":10}';
+   }
+   ```
+
+3. **Document mock limitation** in test file header:
+   ```
+   Note: These tests run against an nginx mock, NOT a real eBPF agent.
+   Real eBPF testing requires Linux kernel 4.4+ with CAP_BPF.
+   The mock validates API contract compliance and UI integration only.
+   For kernel-level eBPF verification, see src/Scanner/.../LinuxEbpfCaptureAdapter.cs
+   ```
+
+4. **(Future, not this sprint):** Plan for real eBPF testing:
+   - Linux CI runner with privileged mode
+   - Tetragon agent container (Cilium's eBPF runtime)
+   - Event generation harness (trigger syscalls, verify capture)
+
+Completion criteria:
+- [ ] 3+ new edge case tests added to `runtime-hosts.e2e.spec.ts`
+- [ ] Degraded health fixture endpoint added
+- [ ] Mock limitation documented in test file header
+- [ ] All tests pass in full suite run

+
+### TASK-5 — Missing Source Connector Inventory and Roadmap
+Status: TODO
+Dependency: TASK-2
+Owners: Product Manager / Developer
+
+**Context:** 70 advisory sources are defined in `SourceDefinitions.cs` but only 27 have full fetch/parse/map connectors. Notable missing:
+- **NVD** (NIST National Vulnerability Database) — THE primary CVE source
+- **RHEL/CentOS/Fedora** — major Linux distro advisories
+- **npm/PyPI/Maven/RubyGems** — package ecosystem advisories
+- **AWS/Azure/GCP** — cloud platform advisories
+- **Juniper/Fortinet/PaloAlto** — network vendor advisories
+
+**Tasks:**
+
+1. Audit which 38 missing sources are:
+   - **Priority 1 (critical gap):** NVD, CVE
+   - **Priority 2 (high value):** RHEL, Fedora, npm, PyPI, Maven
+   - **Priority 3 (vendor-specific):** AWS, Azure, Juniper, Fortinet, etc.
+   - **Priority 4 (niche/regional):** CERT-AT, CERT-BE, CERT-CH, etc.
+
+2. For Priority 1 sources, create implementation tasks (separate sprints)
+
+3. Document the source coverage matrix in `docs/modules/concelier/source-coverage.md`
+
+Completion criteria:
+- [ ] Source coverage matrix documented with priorities
+- [ ] NVD/CVE implementation tasks created as separate sprints
+- [ ] Coverage gaps visible in documentation

+
+## Decisions & Risks
+
+- **D1:** Advisory pipeline tests gated behind `E2E_ADVISORY_PIPELINE=1` because they trigger real sync jobs (slow, require Concelier + fixture data)
+- **D2:** Rekor tests gated behind `E2E_REKOR=1` because they require `--profile sigstore-local` compose startup
+- **D3:** eBPF Agent remains mock-only in CI — real kernel testing deferred to dedicated Linux CI runner (future sprint)
+- **D4:** Advisory fixture serves deterministic data (not fetched from external sources) to maintain offline-first posture
+- **R1:** Advisory pipeline tests depend on Concelier job execution timing — may need generous polling timeouts (120s+)
+- **R2:** Canonical merge tests depend on both KEV and GHSA connectors pointing at fixture URLs — may require Concelier config override
+- **R3:** GHSA fixture needs to match the connector's expected REST API format exactly (pagination headers, rate limit headers)
+
+## Next Checkpoints
+
+- TASK-1 (GitHubApp): Quick win, can ship independently
+- TASK-2 (Advisory Pipeline): Largest task, most complex fixture setup
+- TASK-3 (Rekor): Requires sigstore-local profile — verify rekor-v2 container starts cleanly first
+- TASK-4 (eBPF Hardening): Small incremental improvement
+- TASK-5 (Source Roadmap): Documentation/planning task, no code

+ * Advisory Pipeline — End-to-End Tests
+ *
+ * Tests the full advisory source aggregation pipeline:
+ *   1. Fixture data serving (KEV JSON, GHSA list, EPSS CSV)
+ *   2. Initial sync: trigger source sync, verify advisory count increases
+ *   3. Incremental sync: re-sync same data, verify no duplicates
+ *   4. Cross-source merge: same CVE from KEV + GHSA → single canonical with 2 edges
+ *   5. Canonical query API: pagination, CVE lookup, score distribution
+ *
+ * Gate: E2E_ADVISORY_PIPELINE=1 (these trigger real sync jobs and take longer)
+ *
+ * Prerequisites:
+ *   - Main Stella Ops stack running
+ *   - docker-compose.integration-fixtures.yml (advisory-fixture with data/ mount)
+ *   - Concelier service running and connected to advisory-fixture
