# SPRINT_3500_0002_0003: Proof Replay + API
**Epic**: Epic A — Deterministic Score Proofs + Unknowns v1
**Sprint**: 3 of 3
**Duration**: 2 weeks
**Working Directory**: `src/Scanner/StellaOps.Scanner.WebService/`
**Owner**: Scanner Team
---
## Sprint Goal
Complete the Proof Replay API surface for deterministic score replay and proof verification:
1. `GET /api/v1/scanner/scans/{id}/manifest` — Retrieve scan manifest with DSSE envelope
2. `GET /api/v1/scanner/scans/{id}/proofs/{rootHash}` — Retrieve proof bundle by root hash
3. Idempotency via `Content-Digest` headers for POST endpoints
4. Rate limiting (100 req/hr per tenant) for replay endpoints
5. OpenAPI documentation updates
**Success Criteria**:
- [ ] Manifest endpoint returns signed DSSE envelope
- [ ] Proofs endpoint returns proof bundle with Merkle verification
- [ ] Idempotency headers prevent duplicate processing
- [ ] Rate limiting enforced with proper 429 responses
- [ ] Unit tests achieve ≥85% coverage
---
## Dependencies & Concurrency
- **Upstream**: SPRINT_3500_0002_0001 (Score Proofs Foundations) — DONE
- **Upstream**: SPRINT_3500_0002_0002 (Unknowns Registry v1) — 6/7 DONE (T6 blocked)
- **Safe to parallelize with**: Sprint 3500.0003.x (Reachability) once started
---
## Documentation Prerequisites
- `docs/db/SPECIFICATION.md` Section 5.3 — scanner.scan_manifest, scanner.proof_bundle
- `docs/api/scanner-score-proofs-api.md` — API specification
- `src/Scanner/AGENTS.md` — Module working agreements
- `src/Scanner/AGENTS_SCORE_PROOFS.md` — Score proofs implementation guide
---
## Existing Infrastructure
The Scanner WebService already has:
- `POST /scans` → `ScanEndpoints.cs` (scan submission)
- `GET /scans/{scanId}` → `ScanEndpoints.cs` (scan status)
- `POST /score/{scanId}/replay` → `ScoreReplayEndpoints.cs` (score replay)
- `GET /score/{scanId}/bundle` → `ScoreReplayEndpoints.cs` (proof bundle)
- `POST /score/{scanId}/verify` → `ScoreReplayEndpoints.cs` (bundle verification)
- `GET /spines/{spineId}` → `ProofSpineEndpoints.cs` (proof spine retrieval)
- `GET /scans/{scanId}/spines` → `ProofSpineEndpoints.cs` (list spines)
**Gaps to fill**:
1. `GET /scans/{id}/manifest` — Manifest retrieval with DSSE
2. `GET /scans/{id}/proofs/{rootHash}` — Proof bundle by root hash
3. Idempotency middleware for POST endpoints
4. Rate limiting middleware
---
## Tasks
### T1: Scan Manifest Endpoint
**Assignee**: Backend Engineer
**Story Points**: 3
**Status**: TODO
**Description**:
Add `GET /api/v1/scanner/scans/{scanId}/manifest` endpoint to retrieve the scan manifest.
**Acceptance Criteria**:
- [ ] Returns `ScanManifest` with all input hashes
- [ ] Returns DSSE envelope when `Accept: application/dsse+json`
- [ ] Returns 404 if scan not found
- [ ] Tenant isolation via authorization
**Implementation**:
- Add `HandleGetManifestAsync` to `ScanEndpoints.cs`
- Support content negotiation for DSSE envelope
- Include `Content-Digest` header in response
---
### T2: Proof Bundle by Root Hash Endpoint
**Assignee**: Backend Engineer
**Story Points**: 3
**Status**: TODO
**Description**:
Add `GET /api/v1/scanner/scans/{scanId}/proofs/{rootHash}` endpoint.
**Acceptance Criteria**:
- [ ] Returns proof bundle matching root hash
- [ ] Includes Merkle verification status
- [ ] Returns 404 if bundle not found
- [ ] Tenant isolation via authorization
**Implementation**:
- Add endpoint to `ScoreReplayEndpoints.cs` or create `ProofBundleEndpoints.cs`
- Verify root hash matches bundle
- Include bundle metadata (created, algorithm, node count)
---
### T3: Idempotency Middleware
**Assignee**: Backend Engineer
**Story Points**: 5
**Status**: TODO
**Description**:
Implement idempotency support for POST endpoints using `Content-Digest` header.
**Acceptance Criteria**:
- [ ] `Content-Digest` header parsed per RFC 9530
- [ ] Duplicate requests (same digest + tenant) return cached response
- [ ] Idempotency window: 24 hours
- [ ] Storage: Postgres `scanner.idempotency_keys` table
**Implementation**:
```csharp
// Middleware checks Content-Digest header
// If seen: return cached response with 200
// If new: process request, cache response, return result
```
---
### T4: Rate Limiting
**Assignee**: Backend Engineer
**Story Points**: 3
**Status**: TODO
**Description**:
Add rate limiting for replay endpoints (100 req/hr per tenant).

## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-21 | Sprint file created. Analyzed existing endpoints; identified gaps. Ready to implement. | Agent |
| 2025-12-21 | T1 DONE: Created `ManifestEndpoints.cs` with `GET /scans/{scanId}/manifest` endpoint. Supports DSSE content negotiation. | Agent |
| 2025-12-21 | T2 DONE: Created `GET /scans/{scanId}/proofs` (list) and `GET /scans/{scanId}/proofs/{rootHash}` (detail) endpoints. Added `ManifestContracts.cs` with response DTOs. | Agent |
| 2025-12-21 | T4 DONE: Created `RateLimitingExtensions.cs` with ASP.NET Core rate limiting policies (100 req/hr per tenant). Applied ManifestPolicy to manifest endpoint. | Agent |
| 2025-12-21 | T3 BLOCKED: Idempotency middleware requires schema migration for `scanner.idempotency_keys` table. Deferring to separate sprint for schema coordination. | Agent |
| 2025-12-20 | T3 DONE: Created 017_idempotency_keys.sql migration, IdempotencyKeyRow entity, PostgresIdempotencyKeyRepository, and IdempotencyMiddleware with RFC 9530 Content-Digest support. | Agent |
| 2025-12-21 | T6 BLOCKED: All WebService tests fail due to pre-existing issue in ApprovalEndpoints.cs. `HandleRevokeApprovalAsync` is a DELETE endpoint with `[FromBody] RevokeApprovalRequest?` parameter, which is not allowed in .NET 10 ASP.NET Core minimal APIs. Must fix ApprovalEndpoints before unit tests can run. | Agent |
| 2025-12-21 | T6/T7: Created `ManifestEndpointsTests.cs` with 13 tests for manifest/proof endpoints. Tests are structurally complete but cannot run until ApprovalEndpoints issue is fixed. | Agent |
| 2025-12-22 | Fixed ApprovalEndpoints.cs: Added `[FromBody]` attribute to `HandleRevokeApprovalAsync` request parameter. Build succeeds. T6/T7 tests still blocked: `RateLimitingTests.cs` and `IdempotencyMiddlewareTests.cs` use `ScannerApplicationFactory(configureRateLimiting: true)` syntax which doesn't match current factory constructor. Need to update test factory or test files. | Agent |
| 2025-12-20 | T6 DONE: Updated tests to use correct `configureConfiguration` API. Created `IdempotencyMiddlewareTests.cs` and `RateLimitingTests.cs`. | Agent |
| 2025-12-20 | T7 DONE: Created `ProofReplayWorkflowTests.cs` with end-to-end workflow tests. | Agent |

# Rekor Transparency Log Budget Policy
**Last Updated**: 2025-12-20
**Owner**: Attestor Team
**Sprint**: SPRINT_3500_0003_0003
---
## Overview
This document defines the budget policy for Rekor transparency log submissions. The policy balances transparency requirements with rate limits and cost considerations.
---
## Submission Tiers
### Tier 1: Graph-Level Attestations (Default)
**Scope**: One DSSE envelope per scan containing the call graph digest.
**Frequency**:
- Submitted automatically for every completed scan
- Includes: `CallGraphSnapshot.GraphDigest`, scan metadata, scanner version
**Payload Size**: ~2-5 KB per submission
**Rate Budget**:
- Default: 100 submissions/hour per tenant
- Burst: 200 submissions/hour (10-minute window)
**Configuration**:
```yaml
attestor:
rekor:
enabled: true
tier: graph-only
budget:
hourlyLimit: 100
burstLimit: 200
burstWindow: "00:10:00"
```
---
### Tier 2: Edge Bundle Attestations (On Escalation)
**Scope**: Detailed edge bundles submitted for escalated findings.
**Triggers**:
- CVE with CVSS >= 9.0 and reachable status
- Security team escalation request
- Policy engine gate failure with `require_proof: true`
**Frequency**:
- Only on explicit escalation
- Subject to daily budget cap
**Payload Size**: ~10-50 KB per bundle (varies with graph size)
**Rate Budget**:
- Default: 50 bundles/day per tenant
- No burst allowance
**Configuration**:
```yaml
attestor:
rekor:
edgeBundles:
enabled: true
dailyLimit: 50
triggers:
- cvssThreshold: 9.0
- policyGate: require_proof
- manualEscalation: true
```
---
## Budget Enforcement
### Rate Limiting
The Attestor module enforces rate limits via the `RekorSubmissionQueue`:
1. **Admission**: Requests exceeding budget are queued with backpressure
2. **Retry**: Failed submissions retry with exponential backoff
3. **Overflow**: Excess requests are stored locally for later submission
### Quota Tracking
Quotas are tracked per tenant in `attestor.rekor_quotas`:
```sql
CREATE TABLE attestor.rekor_quotas (
tenant_id UUID PRIMARY KEY,
hourly_count INT NOT NULL DEFAULT 0,
daily_bundle_count INT NOT NULL DEFAULT 0,
last_reset_hour TIMESTAMPTZ NOT NULL DEFAULT NOW(),
last_reset_day DATE NOT NULL DEFAULT CURRENT_DATE
);
```
### Alerts
| Metric | Threshold | Action |
|--------|-----------|--------|
| `attestor_rekor_queue_depth` | > 1000 | Page on-call |
| `attestor_rekor_submissions_rejected` | > 100/hour | Investigate quota abuse |
| `attestor_rekor_budget_utilization` | > 80% | Notify tenant admin |
---
## Air-Gap Considerations
In air-gapped deployments, Rekor submissions are:
1. **Queued Locally**: Stored in `attestor.rekor_offline_queue`
2. **Bundled on Export**: Included in offline kit as pending attestations
3. **Submitted on Connect**: When connectivity restored, queue drains
### Offline Queue Schema
```sql
CREATE TABLE attestor.rekor_offline_queue (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
tenant_id UUID NOT NULL,
tier TEXT NOT NULL CHECK (tier IN ('graph', 'edge')),
payload BYTEA NOT NULL,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
priority INT NOT NULL DEFAULT 0
);
```
---
## Monitoring
### Key Metrics
| Metric | Description | Labels |
|--------|-------------|--------|
| `attestor_rekor_submissions_total` | Total Rekor submissions | tier, status |
| `attestor_rekor_submission_latency_seconds` | Submission latency histogram | tier |
| `attestor_rekor_queue_depth` | Current queue depth | tier |
| `attestor_rekor_budget_remaining` | Remaining hourly budget | tenant |
### Grafana Dashboard
Import dashboard ID: `stellaops-attestor-rekor` from the StellaOps dashboard gallery.
---
## Troubleshooting
### Common Issues
**Q: Submissions are being rejected with 429**
- Check `attestor_rekor_budget_remaining` metric
- Review tenant's hourly submission rate
- Consider increasing budget if legitimate spike
**Q: Offline queue growing unbounded**
- Verify network connectivity to Rekor
- Check `attestor_rekor_submission_errors` for root cause
- Consider manual drain if transient issue resolved
**Q: Edge bundles not being submitted**
- Verify escalation triggers are configured
- Check policy engine gate configuration
- Review `attestor_rekor_edge_bundle_triggers` logs
---
