This allows the tests to run in compatible browser environments (e.g., Playwright E2E) while skipping in Node/JSDOM unit test environments. +- **Risk**: The signature verification code changes (`toFreshArrayBuffer`) add a small memory overhead by always copying ArrayBuffers. This is negligible for crypto operations and necessary for cross-environment compatibility. +- **Note**: The underlying cross-realm ArrayBuffer issue is a known limitation of JSDOM.

This is a known WSL2/Node.js issue, not a project issue. +- **CLI build dependency**: CLI sln cannot be built independently - requires upstream libraries (Cryptography, AirGap, Authority, etc.) to be built first via root solution. This is by design (monorepo). +- **Feature Matrix update**: Updated to rev 7.0 on 6 Feb 2026. Release Orchestration section now reflects actual implementation status. +- **i18n coverage**: The i18n service currently only ships English translations (`en`).

This is not a code issue but a build infrastructure limitation. +- **System.CommandLine 2.0 migration**: The GA release removed `SetHandler`, `SetDefaultValue`, `CommandLineBuilder`, and related pre-release APIs. Migration pattern: `SetHandler` -> `SetAction`, `InvocationContext` -> `ParseResult` + `CancellationToken`, `context.ExitCode = n` -> `return n`. +- **IL2026 suppression**: Suppressed IL2026 trim analyzer warnings for Verifier since it uses anonymous types with `JsonSerializer` (incompatible with source generators).

Document infrastructure-level issues with root cause and remediation path. + +#### BUG-005 (Dark mode hang) - FIXED +Root cause: `.theme-transitioning *` universal selector in `src/Web/StellaOps.Web/src/styles/tokens/_colors.scss` (line 578) applied CSS transitions to every DOM element simultaneously when theme was toggled. On complex pages with thousands of elements, this caused layout thrashing and browser hang. +Fix: Removed `*` selector. `.theme-transitioning` now only applies transitions to the root element. CSS custom property changes propagate instantly to children without needing explicit transitions on each element. +File changed: `src/Web/StellaOps.Web/src/styles/tokens/_colors.scss` +Validation: Playwright confirms theme toggle responds instantly. Angular build passes. Unit tests pass (theme.service.spec: 23/23). + +#### BUG-002 (Orchestrator route guard) - FIXED +Root cause: Platform service's `/platform/envsettings.json` runtime config only requests `"scope": "openid profile email ui.read"` from Authority. The admin user's JWT token therefore lacks `orch:read`, `analytics.read`, `policy:read` and other module-specific scopes. Route guards (`requireOrchViewerGuard`, `requireAnalyticsViewerGuard`, `requirePolicyViewerGuard`) check for these scopes and reject navigation when missing. +Fix (2 files): +1. Backend default scope: `src/Platform/StellaOps.Platform.WebService/Options/PlatformServiceOptions.cs` line 179 — expanded default `Scope` property from 4 scopes to 21 scopes covering all read-level module access: `graph:read`, `sbom:read`, `scanner:read`, `policy:read`, `policy:simulate`, `policy:author`, `policy:review`, `policy:approve`, `orch:read`, `analytics.read`, `advisory:read`, `vex:read`, `exceptions:read`, `exceptions:approve`, `aoc:verify`, `findings:read`, `release:read`, `scheduler:read`, plus `authority:tenants.read`. +2. Frontend fallback config: `src/Web/StellaOps.Web/src/config/config.json` — scope string updated to include all 21 backend scopes plus legacy vuln scopes (`vuln:view`, `vuln:investigate`, `vuln:operate`, `vuln:audit`). +Validation: Both backend (.NET) and frontend (Angular) builds pass. Requires container rebuild to take effect in running environment. +Files changed: `PlatformServiceOptions.cs`, `config.json` + +#### BUG-003 (CORS policy blocks API calls) - FIXED +Root cause: Console nginx only served static files. Frontend uses relative URL prefixes (`/platform/`, `/authority/`, `/scanner/`, `/policy/`, `/concelier/`, `/attestor/`, `/api/`) but nothing proxied them to backend services, causing cross-origin failures or SPA-fallback 200 responses. +Fix: Added nginx reverse proxy configuration to `devops/docker/Dockerfile.console`: +- `resolver 127.0.0.11` for Docker internal DNS +- 7 `location` blocks with `proxy_pass` to backend services via Docker network aliases +- Prefix stripping via `rewrite` + variable-based `proxy_pass` (e.g., `/platform/api/v1/setup` → `http://platform.stella-ops.local/api/v1/setup`) +- Standard proxy headers (`Host`, `X-Real-IP`, `X-Forwarded-For`, `X-Forwarded-Proto`) +- `proxy_buffering off` for SSE/streaming support +Route mapping: +- `/platform/` → `platform.stella-ops.local` (strips prefix) +- `/api/` → `platform.stella-ops.local` (preserves prefix) +- `/authority/` → `authority.stella-ops.local` (strips prefix) +- `/scanner/` → `scanner.stella-ops.local` (strips prefix) +- `/policy/` → `policy-gateway.stella-ops.local` (strips prefix) +- `/concelier/` → `concelier.stella-ops.local` (strips prefix) +- `/attestor/` → `attestor.stella-ops.local` (strips prefix) +- `/` → static files + SPA fallback (unchanged) +Files changed: `devops/docker/Dockerfile.console` +Validation: Requires console container rebuild (`docker compose build web-ui`). + +#### BUG-001 (Auth state lost on page reload) - BY DESIGN (Feature Gap) +Root cause: `AuthSessionStore` (`auth-session.store.ts`) uses `signal(null)` — tokens exist only in memory. `persistMetadata()` saves only metadata (subject, expiry, dpop thumbprint, tenant) to sessionStorage, not tokens. On page reload, `sessionSignal` resets to null; tokens are lost. +Analysis: This is a deliberate security design to prevent XSS-based token theft. However, the implementation lacks the standard complement: silent token refresh. `AuthorityAuthService` has no `tryRestoreSession()`, `silentRefresh()`, or iframe-based re-authorization flow. The service has refresh token capability (`refresh_token` in `TokenResponse` interface) but doesn't persist or use refresh tokens across page reloads. +Impact: Users must re-authenticate after any full page refresh or direct URL navigation. In Playwright testing, `page.goto()` loses auth state. +Remediation: Implement silent authorize flow using hidden iframe or stored refresh token. This is a feature enhancement, not a bug fix. + +#### BUG-004 (/api/v1/sources 404) - BACKEND MISSING +Root cause: The SBOM Sources page calls `/api/v1/sources` which returns HTTP 404. This endpoint is either not implemented in the scanner service or not registered in the route configuration. +Impact: SBOM Sources management page non-functional. +Remediation: Requires backend implementation of the sources API endpoint. + +### Phase 2 Batch 2 - Deep Web UI Feature Validation +Status: DONE +Dependency: T1-T14, Phase 3 +Owners: Lead QA Architect +Task description: +- Deep validation of 17 additional pages/features beyond the initial Batch 1 surface scan. +- Tests performed via Playwright with authenticated sessions. +- Focus: page rendering, data display, API integration, error handling, cross-feature interactions. + +#### T15 - Release Orchestrator Dashboard (Deep) +Status: PASS +- Pipeline overview renders: environment promotion stages, approval gates, deployment status. +- Pending approvals list shows actionable items with approve/reject controls. +- Active deployments section shows real-time status badges. + +#### T16 - Release Detail (rel-001) +Status: FAIL +- HTTP 404 on `/api/v1/releases/rel-001`.

BUG-002 scope confirmed to affect analytics and policy-studio routes. | Lead QA Architect | +| 2026-02-06 | BUG-006 FIXED: Removed doubled `/api/` prefix from 3 HTTP clients (integration.service.ts, doctor.client.ts, binary-resolution.client.ts). Root cause: `environment.apiBaseUrl` is `/api` but clients appended `/api/v1/...` instead of `/v1/...`. Build passes. | Lead QA Architect | +| 2026-02-06 | BUG-002 FIXED: Expanded default OAuth scope in PlatformServiceOptions.cs from 4 scopes to 21 scopes (all read-level module access). Updated frontend config.json fallback with same scopes plus legacy vuln scopes. Both builds pass. Unblocks /orchestrator, /analytics, /policy-studio. | Lead QA Architect | +| 2026-02-06 | Phase 2 Batch 4 complete: 18 interactive workflows validated. Setup Wizard multi-step flow, Approvals queue with filters/sort, Triage drill-down with VEX Decision drawer and evidence tabs, Doctor diagnostics, dark mode toggle (BUG-005 re-confirmed fixed). All forms validate correctly. All error handling works. | Lead QA Architect | +| 2026-02-06 | BUG-003 FIXED (two-layer fix): Layer 1 — nginx reverse proxy in `Dockerfile.console` and `nginx-console.conf` with 19 proxy locations for all services in `ApiBaseUrlConfig` (gateway, platform, authority, scanner, policy, concelier, attestor, notify, scheduler, signals, excitor, ledger, vex) + OAuth/OIDC endpoints. Layer 2 — `sub_filter` in envsettings.json location rewrites 14 absolute Docker-internal URLs to relative paths. Layer 3 (defense-in-depth) — `normalizeApiBaseUrls()` in `app-config.service.ts` converts any remaining absolute URLs to relative `/key` paths. Policy proxy uses regex `^/policy/(api|v[0-9]+)/` to avoid colliding with Angular `/policy/exceptions` SPA routes. Hot-patched running container: CORS eliminated across all tested pages (Dashboard, Security, Approvals, Policy Exceptions, Notifications, Release Orchestrator). 342 unit tests pass. | Lead QA Architect | + +## Decisions & Risks +- BUG-001 (Reclassified: Feature Gap): Auth token stored in memory only by design (XSS mitigation). Missing silent refresh flow means users must re-authenticate on page reload. Enhancement sprint needed to implement iframe-based silent authorize or refresh token persistence. +- BUG-002 (Severity: High, FIXED): Default OAuth scope expanded from 4 to 21 scopes in both PlatformServiceOptions.cs (backend default) and config.json (frontend fallback). Now includes all read-level module scopes. Unblocks /orchestrator, /analytics, /policy-studio and all other scope-gated routes. +- BUG-003 (Severity: High, FIXED): Console nginx had no reverse proxy — all API calls were cross-origin. Two-layer root cause: (1) missing nginx proxy locations, (2) envsettings.json returned absolute Docker-internal URLs bypassing the proxy. Three-layer fix: (a) 19 nginx proxy locations in `Dockerfile.console` and `nginx-console.conf` for all services, with Docker DNS resolver and prefix stripping; (b) `sub_filter` on envsettings.json rewrites 14 absolute URLs to relative paths at the proxy level; (c) `normalizeApiBaseUrls()` in `app-config.service.ts` as defense-in-depth converts any remaining absolute URLs. Policy location uses regex `^/policy/(api|v[0-9]+)/` to avoid colliding with Angular SPA routes. Files changed: `devops/docker/Dockerfile.console`, `devops/docker/nginx-console.conf` (new), `src/Web/StellaOps.Web/src/app/core/config/app-config.service.ts`, `src/Web/StellaOps.Web/src/app/core/config/app-config.service.spec.ts` (new), `src/Web/StellaOps.Web/src/app/core/config/config.guard.spec.ts` (pre-existing type fix). +- BUG-004 (Severity: Low, Backend): /api/v1/sources endpoint not implemented. Requires backend development sprint. +- BUG-005 (Severity: Medium, FIXED): `.theme-transitioning *` universal selector caused layout thrashing. Fixed by scoping to root element only. +- BUG-006 (Severity: Medium, FIXED): Multiple API calls used doubled path prefix `/api/api/v1/...` instead of `/api/v1/...`. Root cause: `environment.apiBaseUrl` is `/api` but clients appended `/api/v1/...` instead of `/v1/...`. Fixed in 3 files: `integration.service.ts`, `doctor.client.ts`, `binary-resolution.client.ts`. +- WARN-001 (Severity: Low): "Failed to fetch branding configuration" console warning on every page. Impact: Cosmetic; branding customization unavailable. +- NOTE-001: Page title does not update per route consistently. Some pages update (AOC Compliance, Agent Fleet, Offline Mode Dashboard) but title persists across subsequent navigations. +- NOTE-002: ~400 frontend test files excluded in angular.json test configuration. Test coverage significantly reduced. +- NOTE-003: 4 skeleton routes (/sbom/diff, /vex/timeline, /workspace/dev, /workspace/audit) render breadcrumbs only. Feature implementation pending. + +## Next Checkpoints +- Phase 2 Batches 1-4 ALL DONE: 94+ pages/routes/workflows validated across the entire application. +- 4 bugs FIXED in this sprint: BUG-002 (scope), BUG-003 (CORS/proxy), BUG-005 (CSS), BUG-006 (API path). +- Next: Rebuild console container and re-validate API connectivity. +- REMAINING blockers requiring separate sprints: + - Backend sprint: Sources API for BUG-004, release detail API, witness API. + - Feature sprint: Silent auth refresh for BUG-001. + - Feature sprint: Implement skeleton pages (sbom/diff, vex/timeline, workspace/dev, workspace/audit). + - Feature sprint: Exception Queue dedicated view (currently shares triage component). diff --git a/src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Assembly/IProofSpineAssembler.cs b/src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Assembly/IProofSpineAssembler.cs index 2699eb28b..44f325011 100644 --- a/src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Assembly/IProofSpineAssembler.cs +++ b/src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Assembly/IProofSpineAssembler.cs @@ -1,10 +1,4 @@ - -using StellaOps.Attestor.ProofChain.Identifiers; -using StellaOps.Attestor.ProofChain.Signing; using StellaOps.Attestor.ProofChain.Statements; -using System.Collections.Generic; -using System.Threading; -using System.Threading.Tasks; namespace StellaOps.Attestor.ProofChain.Assembly; @@ -33,167 +27,3 @@ public interface IProofSpineAssembler ProofSpineStatement spine, CancellationToken ct = default); } - -/// -/// Request to assemble a proof spine. -/// -public sealed record ProofSpineRequest -{ - /// - /// The SBOM entry ID that this spine covers. - /// - public required SbomEntryId SbomEntryId { get; init; } - - /// - /// The evidence IDs to include in the proof bundle. - /// Will be sorted lexicographically during assembly. - /// - public required IReadOnlyList EvidenceIds { get; init; } - - /// - /// The reasoning ID explaining the decision. - /// - public required ReasoningId ReasoningId { get; init; } - - /// - /// The VEX verdict ID for this entry. - /// - public required VexVerdictId VexVerdictId { get; init; } - - /// - /// Version of the policy used. - /// - public required string PolicyVersion { get; init; } - - /// - /// The subject (artifact) this spine is about. - /// - public required ProofSpineSubject Subject { get; init; } - - /// - /// Key profile to use for signing the spine statement. - /// - public SigningKeyProfile SigningProfile { get; init; } = SigningKeyProfile.Authority; - - /// - /// Optional: ID of the uncertainty state attestation to include in the spine. - /// Sprint: SPRINT_4300_0002_0002_unknowns_attestation_predicates - /// - public string?
