# Sprint SPRINT_20260107_005_001_LB - CycloneDX 1.7 Evidence Models
> **Parent:** [SPRINT_20260107_005_000_INDEX](./SPRINT_20260107_005_000_INDEX_cyclonedx17_native_fields.md)
> **Status:** DONE
> **Last Updated:** 2026-01-09
## Objective
Implement native CycloneDX 1.7 evidence field population in the Scanner SBOM generation pipeline, replacing custom `stellaops:evidence[n]` properties with spec-compliant `component.evidence.*` structures.
## Working Directory
- `src/Scanner/__Libraries/StellaOps.Scanner.Emit/`
- `src/Scanner/__Tests/StellaOps.Scanner.Emit.Tests/`
## Prerequisites
- None (foundation sprint)
## Dependencies
| Dependency | Package | Usage |
|------------|---------|-------|
| CycloneDX | `CycloneDX.Models` | Evidence model classes |
| Scanner Core | `StellaOps.Scanner.Core` | Component evidence data |
---
## Current Implementation
Evidence is stored as custom properties in `CycloneDxComposer.cs`:
```csharp
// CURRENT: Custom property storage (lines 400-414)
for (var index = 0; index < component.Evidence.Length; index++)
{
var evidence = component.Evidence[index];
properties.Add(new Property
{
Name = $"stellaops:evidence[{index}]",
Value = $"{evidence.Kind}:{evidence.Value}@{evidence.Source}",
});
}
```
## Target Implementation
Use native CycloneDX 1.7 evidence fields:
```csharp
// TARGET: Native evidence field population
var cdxComponent = new Component
{
Evidence = new Evidence
{
Identity = BuildIdentityEvidence(component),
Occurrences = BuildOccurrences(component),
Licenses = BuildLicenseEvidence(component),
Copyright = BuildCopyrightEvidence(component),
}
};
```

## Decisions & Risks
| Decision/Risk | Notes |
|---------------|-------|
| Diff syntax highlighting | Use Prism.js or similar lightweight library |
| Runtime polling | WebSocket preferred; fallback to 5s interval |
| Large diffs | Truncate at 500 lines; link to full view |

# Sprint SPRINT_20260107_006_003_BE - AdvisoryAI Chat Interface
> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
> **Status:** DONE
> **Last Updated:** 2026-01-09
## Objective
Implement a conversational chat interface for AdvisoryAI, enabling multi-turn dialogue while maintaining grounded responses with object links. The model can propose actions, but execution is gated by policy-aware automation.
## Working Directory
- `src/AdvisoryAI/StellaOps.AdvisoryAI/Chat/`
- `src/AdvisoryAI/StellaOps.AdvisoryAI.WebService/Endpoints/`
- `src/Web/StellaOps.Web/src/app/features/advisory-ai/`
## Prerequisites
- Existing: AdvisoryAI grounded responses
- Existing: Guardrail pipeline
---
## Advisory Vision
> "**Grounded answers only**: model responses must cite **internal object links** (SBOM IDs, DSSE URIs, call-graph nodes).
> **Guardrails**: model can propose actions, but execution is gated by **Policy-aware Automation**."
## Example User Flows
**Flow 1: Integration Question**
```
User: "How do I integrate GitLab?"
AdvisoryAI:
Here's how to integrate GitLab with StellaOps:
**Steps:**
1. Create GitLab application (Admin → Applications)
2. Configure OIDC claims: `groups`, `email`
3. Add webhook secret to StellaOps Authority
**One-click setup:**
[Generate Integration Manifest] ← Button
**References:**
- Authority keys: [auth:keys/gitlab-oidc ↗]
- Webhook URL: `https://stellaops.example.com/webhooks/gitlab`
- Required scopes: [docs:scopes/ci-webhook ↗]
```
**Flow 2: Exploitability Question**
```
User: "Is CVE-2023-44487 exploitable here?"
AdvisoryAI:
**Verdict:** ⚠️ AFFECTED (reachable)
**Evidence:**
- Reachability: [reach:api-gateway:grpc.Server ↗] → 95% confident
- Runtime: 1,247 hits in last 24h [runtime:api-gateway:traces ↗]
- EPSS: 0.97 (top 1% exploitability)
**Recommendation:** Upgrade to patched version or apply WAF rule.
**Actions:**
[Approve] [Quarantine] [Defer with VEX]
```

## Decisions & Risks
| Decision/Risk | Notes |
|---------------|-------|
| Conversation TTL | 24 hours default; configurable per tenant |
| Streaming vs polling | SSE for real-time; polling fallback |
| Action execution | Always requires explicit user confirmation |
| Token budget | 8k context window; truncate oldest turns |

# Sprint SPRINT_20260107_006_005_BE - Reproduce Button Implementation
> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
> **Status:** DONE
> **Last Updated:** 2026-01-09
## Objective
Complete the Reproduce button implementation, enabling auditors to trigger deterministic replay using the same feed hashes, rules, and seeds to recreate any verdict. This is the key differentiator: "auditors rerun your exact decision graph; rivals hand over PDFs."
## Working Directory
- `src/Timeline/StellaOps.Timeline.WebService/Endpoints/`
- `src/Replay/StellaOps.Replay.Core/`
- `src/Web/StellaOps.Web/src/app/shared/components/reproduce/`
## Prerequisites
- Existing: `ITimelineReplayOrchestrator` interface (defined)
- Existing: `ReplayEndpoints.cs` (stubbed)
- Existing: Timeline module with HLC ordering
---
## Advisory Vision
> "**Reproduce** button: spins deterministic replay using the same feed hashes, rules, and seeds to recreate the verdict."
## Current State
The replay interface is defined but endpoints are stubbed:
- `ITimelineReplayOrchestrator` - interface exists
- `ReplayOperation` model - defined
- `ReplayEndpoints` - has TODO markers
## Target State
Fully functional Reproduce button:
1. User clicks "Reproduce" on any verdict
2. System queues replay job with input manifests
3. Replay engine recreates verdict with same inputs
4. UI shows progress and comparison result
5. Determinism verification: original digest vs replay digest

POST /api/v1/timeline/{correlationId}/replay
Content-Type: application/json
{
"mode": "verify",

"correlationId": "corr-xyz",
"status": "initiated",
"progress": 0.0,
"statusUrl": "/api/v1/timeline/replay/rpl-abc123"
}
```
### Get Replay Status
```http
GET /api/v1/timeline/replay/rpl-abc123
Response: 200 OK
{
"replayId": "rpl-abc123",
"correlationId": "corr-xyz",

"deterministicMatch": false,
"diff": {
"missingInputs": ["vexDocumentHashes[2]"],
"changedFields": [
{
"path": "verdict.score",
"original": 0.85,
"replay": 0.82,
"reason": "Missing VEX statement"
}
]
}
}
```
---
## Determinism Requirements
For replay to match original:
| Input | Requirement |
|-------|-------------|
| Feed snapshot | Exact same advisory data |
| Policy bundle | Exact same rules version |
| Base image | Same digest (immutable) |
| VEX documents | All referenced VEX available |
| Toolchain | Same scanner/policy engine version |
| Timestamp | Override to original execution time |
| Random seed | Override to original seed |
---
## Decisions & Risks
| Decision/Risk | Notes |
|---------------|-------|
| Async replay | Jobs queued; no blocking UI |
| Input availability | Old inputs may be garbage-collected |
| Mismatch investigation | Provide detailed diff for debugging |

# Sprint 20260107_007_SIGNER_test_stabilization · Signer Test Stabilization
## Topic & Scope
- Stabilize Signer module tests by fixing failing KeyManagement, Fulcio, and negative-request cases.
- Preserve deterministic validation behavior for PoE, DSSE payloads, and certificate time parsing.
- Owning directory: `src/Signer`; evidence: passing `StellaOps.Signer.Tests` and updated test fixtures.
- **Working directory:** `src/Signer`.
## Dependencies & Concurrency
- No upstream sprints required.
- Parallel work in other modules is safe; no shared contracts modified.
## Documentation Prerequisites
- `docs/modules/signer/architecture.md`
- `docs/modules/signer/guides/keyless-signing.md`
- `docs/modules/platform/architecture-overview.md`
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
| --- | --- | --- | --- | --- | --- |
| 1 | SIGNER-TEST-001 | DONE | None | Signer Guild | Fix KeyManagement EF Core JSON mapping to keep tests and in-memory providers stable. |
| 2 | SIGNER-TEST-002 | DONE | SIGNER-TEST-001 | Signer Guild | Correct Fulcio certificate time parsing to avoid DateTimeOffset offset errors. |
| 3 | SIGNER-TEST-003 | DONE | SIGNER-TEST-001 | Signer Guild | Update Signer negative request tests to include PoE where required and keep deep predicate handling deterministic. |
| 4 | SIGNER-TEST-004 | DONE | SIGNER-TEST-002, SIGNER-TEST-003 | Signer Guild | Run Signer tests and record remaining failures. |
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2026-01-08 | Sprint created; tests failing in Signer module. | Planning |
| 2026-01-08 | Completed SIGNER-TEST-001/002/003; started SIGNER-TEST-004. | Codex |
| 2026-01-08 | Completed SIGNER-TEST-004; Signer tests pass after key rotation and chain validation fixes. | Codex |
## Decisions & Risks
- Validate PoE before payload validation; negative tests must include PoE to reach deeper validation paths.
## Next Checkpoints
- 2026-01-09 · Signer test stabilization check-in (Signer Guild).
