feat: add Attestation Chain and Triage Evidence API clients and models

- Implemented Attestation Chain API client with methods for verifying, fetching, and managing attestation chains.
- Created models for Attestation Chain, including DSSE envelope structures and verification results.
- Developed Triage Evidence API client for fetching finding evidence, including methods for evidence retrieval by CVE and component.
- Added models for Triage Evidence, encapsulating evidence responses, entry points, boundary proofs, and VEX evidence.
- Introduced mock implementations for both API clients to facilitate testing and development.

 This repository hosts the StellaOps Concelier service, its plug-in ecosystem, and the
 first-party CLI (`stellaops-cli`). Concelier ingests vulnerability advisories from
-authoritative sources, stores them in MongoDB, and exports deterministic JSON and
+authoritative sources, stores them in PostgreSQL, and exports deterministic JSON and
 Trivy DB artefacts. The CLI drives scanner distribution, scan execution, and job
 control against the Concelier API.
 
 ## Quickstart
 
-1. Prepare a MongoDB instance and (optionally) install `trivy-db`/`oras`.

+# Proof Chain Benchmark Suite
+
+This benchmark suite measures performance of proof chain operations as specified in the Proof and Evidence Chain Technical Reference advisory.
+
+## Overview
+
+The benchmarks focus on critical performance paths:
+
+1. **Content-Addressed ID Generation** - SHA-256 hashing and ID formatting
+2. **Proof Spine Assembly** - Merkle tree construction and deterministic bundling
+3. **Verification Pipeline** - End-to-end verification flow
+4. **Key Rotation Operations** - Trust anchor lookups and key validation
+

+## Regression Detection
+
+Benchmarks are run as part of CI with regression detection:
+
+```yaml
+# .gitea/workflows/benchmark.yaml
+name: Benchmark
+on:
+  pull_request:
+    paths:
+      - 'src/Attestor/**'
+      - 'src/Signer/**'
+
+jobs:
+  benchmark:
+    runs-on: self-hosted
+    steps:
+      - uses: actions/checkout@v4
+      - name: Run benchmarks
+        run: |
+          cd bench/proof-chain
+          dotnet run -c Release -- --exporters json
+      - name: Compare with baseline
+        run: |
+          python3 tools/compare-benchmarks.py \
+            --baseline baselines/proof-chain.json \
+            --current BenchmarkDotNet.Artifacts/results/*.json \
+            --threshold 10
+```
+
+Regressions > 10% will fail the PR check.
+
+## Adding New Benchmarks
+
+1. Create benchmark class in `bench/proof-chain/Benchmarks/`
+2. Follow naming convention: `{Feature}Benchmarks.cs`
+3. Add `[MemoryDiagnoser]` attribute for allocation tracking
+4. Include baseline expectations in XML comments
+5. Update baseline after significant changes:
+   ```bash
+   dotnet run -c Release -- --exporters json
+   cp BenchmarkDotNet.Artifacts/results/*.json baselines/
+   ```
+
+## Performance Guidelines
+
+From advisory §14.1:
+
+| Operation | P50 Target | P99 Target |
+|-----------|------------|------------|
+| Proof Bundle creation | 50ms | 200ms |
+| Proof Bundle verification | 100ms | 500ms |
+| SBOM verification (complete) | 500ms | 2s |
+| Key validity check | 1ms | 5ms |

+## 14 Plugin Version Compatibility (v2.0)
+
+**IMPORTANT:** All plugins **must** declare a `[StellaPluginVersion]` attribute. Plugins without this attribute will be rejected by the host loader.
+
+Declare your plugin's version and host compatibility requirements:
+
+```csharp
+using StellaOps.Plugin.Versioning;
+
+// In AssemblyInfo.cs or any file at assembly level
+[assembly: StellaPluginVersion("1.2.0", MinimumHostVersion = "1.0.0", MaximumHostVersion = "2.0.0")]
+```
+
+| Property | Purpose | Required |
+|----------|---------|----------|
+| `pluginVersion` (constructor) | Your plugin's semantic version | **Yes** |
+| `MinimumHostVersion` | Lowest host version that can load this plugin | Recommended |
+| `MaximumHostVersion` | Highest host version supported | Recommended for cross-major compatibility |
+| `RequiresSignature` | Whether signature verification is mandatory (default: true) | No |
+
+### Version Compatibility Rules
+
+1. **Attribute Required:** Plugins without `[StellaPluginVersion]` are rejected
+2. **Minimum Version:** Host version must be ≥ `MinimumHostVersion`
+3. **Maximum Version:** Host version must be ≤ `MaximumHostVersion` (if specified)
+4. **Strict Major Version:** If `MaximumHostVersion` is not specified, the plugin is assumed to only support the same major version as `MinimumHostVersion`
+
+### Examples
+
+```csharp
+// Plugin works with host 1.0.0 through 2.x (explicit range)
+[assembly: StellaPluginVersion("1.0.0", MinimumHostVersion = "1.0.0", MaximumHostVersion = "2.99.99")]
+
+// Plugin works with host 2.x only (strict - no MaximumHostVersion means same major version)
+[assembly: StellaPluginVersion("1.0.0", MinimumHostVersion = "2.0.0")]
+
+// Plugin version 3.0.0 with no host constraints (uses plugin major version as reference)
+[assembly: StellaPluginVersion("3.0.0")]
+```
+
+---
+
+## 15 Plugin Host Configuration (v2.0)
+
+Configure the plugin loader with security-first defaults in `PluginHostOptions`:
+
+```csharp
+var options = new PluginHostOptions
+{
+    // Version enforcement (all default to true for security)
+    HostVersion = new Version(2, 0, 0),
+    EnforceVersionCompatibility = true,     // Reject incompatible plugins
+    RequireVersionAttribute = true,         // Reject plugins without [StellaPluginVersion]
+    StrictMajorVersionCheck = true,         // Reject plugins crossing major version boundaries
+
+    // Signature verification (opt-in, requires infrastructure)
+    EnforceSignatureVerification = true,
+    SignatureVerifier = new CosignPluginVerifier(new CosignVerifierOptions
+    {
+        PublicKeyPath = "/keys/cosign.pub",
+        UseRekorTransparencyLog = true,
+        AllowUnsigned = false
+    })
+};
+
+var result = await PluginHost.LoadPluginsAsync(options, logger);
+
+// Check for failures
+if (result.HasFailures)
+{
+    foreach (var failure in result.Failures)
+    {
+        logger.LogError("Plugin {Path} failed: {Reason} - {Message}",
+            failure.AssemblyPath, failure.Reason, failure.Message);
+    }
+}
+```
+
+### Host Options Reference
+
+| Option | Default | Purpose |
+|--------|---------|---------|
+| `HostVersion` | null | The host application version for compatibility checking |
+| `EnforceVersionCompatibility` | **true** | Reject plugins that fail version checks |
+| `RequireVersionAttribute` | **true** | Reject plugins without `[StellaPluginVersion]` |
+| `StrictMajorVersionCheck` | **true** | Reject plugins that don't explicitly support the host's major version |
+| `EnforceSignatureVerification` | false | Reject plugins without valid signatures |
+| `SignatureVerifier` | null | The verifier implementation (e.g., `CosignPluginVerifier`) |
+
+### Failure Reasons
+
+| Reason | Description |
+|--------|-------------|
+| `LoadError` | Assembly could not be loaded (missing dependencies, corrupt file) |
+| `SignatureInvalid` | Signature verification failed |
+| `IncompatibleVersion` | Plugin version constraints not satisfied |
+| `MissingVersionAttribute` | Plugin lacks required `[StellaPluginVersion]` attribute |
+
+---
+
+## 16 Fail-Fast Options Validation (v2.0)
+
+Use the fail-fast validation pattern to catch configuration errors at startup:
+
+```csharp
+using StellaOps.DependencyInjection.Validation;
+
+// Register options with automatic startup validation
+services.AddOptionsWithValidation<MyPluginOptions, MyPluginOptionsValidator>(
+    MyPluginOptions.SectionName);
+
+// Or with data annotations
+services.AddOptionsWithDataAnnotations<MyPluginOptions>(
+    MyPluginOptions.SectionName);
+```
+
+Create validators using the base class:
+
+```csharp
+public sealed class MyPluginOptionsValidator : OptionsValidatorBase<MyPluginOptions>
+{
+    protected override string SectionPrefix => "Plugins:MyPlugin";
+
+    protected override void ValidateOptions(MyPluginOptions options, ValidationContext context)
+    {
+        context
+            .RequireNotEmpty(options.BaseUrl, nameof(options.BaseUrl))
+            .RequirePositive(options.TimeoutSeconds, nameof(options.TimeoutSeconds))
+            .RequireInRange(options.MaxRetries, nameof(options.MaxRetries), 0, 10);
+    }
+}
+```
+
+---
+
+## 17 Available Templates (v2.0)
+
+Install and use the official plugin templates:
+
+```bash
+# Install from local templates directory
+dotnet new install ./templates
+
+# Or install from NuGet
+dotnet new install StellaOps.Templates
+
+# Create a connector plugin
+dotnet new stellaops-plugin-connector -n MyCompany.AcmeConnector
+
+# Create a scheduled job plugin
+dotnet new stellaops-plugin-scheduler -n MyCompany.CleanupJob
+```
+
+Templates include:
+- Plugin entry point with version attribute
+- Options class with data annotations
+- Options validator with fail-fast pattern
+- DI routine registration
+- README with build/sign instructions
+
+---
+
+## 18 Migration Guide: v2.0 to v2.1
+
+### Breaking Change: Version Attribute Required
+
+As of v2.1, all plugins **must** include a `[StellaPluginVersion]` attribute. Plugins without this attribute will be rejected with `MissingVersionAttribute` failure.
+
+**Before (v2.0):** Optional, plugins without attribute loaded with warning.
+**After (v2.1):** Required, plugins without attribute are rejected.
+
+### Migration Steps
+
+1. Add the version attribute to your plugin's AssemblyInfo.cs:
+   ```csharp
+   [assembly: StellaPluginVersion("1.0.0", MinimumHostVersion = "2.0.0", MaximumHostVersion = "2.99.99")]
+   ```
+
+2. If your plugin must support multiple major host versions, explicitly set `MaximumHostVersion`:
+   ```csharp
+   // Supports host 1.x through 3.x
+   [assembly: StellaPluginVersion("1.0.0", MinimumHostVersion = "1.0.0", MaximumHostVersion = "3.99.99")]
+   ```
+
+3. Rebuild and re-sign your plugin.
+
+### Opt-out (Not Recommended)
+
+If you must load legacy plugins without version attributes:
+```csharp
+var options = new PluginHostOptions
+{
+    RequireVersionAttribute = false,  // Allow unversioned plugins (NOT recommended)
+    StrictMajorVersionCheck = false   // Allow cross-major version loading
+};
+```
+
+---
+
+## Change Log
+
+| Version | Date | Changes |
+|---------|------|---------|
+| v2.1 | 2025-12-14 | **Breaking:** `[StellaPluginVersion]` attribute now required by default. Added `RequireVersionAttribute`, `StrictMajorVersionCheck` options. Added `MissingVersionAttribute` failure reason. |
+| v2.0 | 2025-12-14 | Added StellaPluginVersion attribute, Cosign verification options, fail-fast validation, new templates |
+| v1.5 | 2025-07-11 | Template install, no hot-reload, IoC conventions |

-- **ABAC attributes** – Tenant roles can project attribute filters (`env`, `owner`, `business_tier`) via the `attributes` block in `authority.yaml` (see the sample `role/vuln-*` definitions). Authority now enforces the same filters on token issuance: client-credential requests must supply `vuln_env`, `vuln_owner`, and `vuln_business_tier` parameters when multiple values are configured, and the values must match the configured allow-list (or `*`). The accepted value pattern is `[a-z0-9:_-]{1,128}`. Issued tokens embed the resolved filters as `stellaops:vuln_env`, `stellaops:vuln_owner`, and `stellaops:vuln_business_tier` claims, and Authority persists the resulting actor chain plus service-account metadata in Mongo for auditability.

Authority enforces the supplied `attributes` during issuance and stores the selected values on the delegation token, making downstream revocation/audit exports aware of the effective ABAC envelope.
 - **Attachment tokens** – Evidence downloads require scoped tokens issued by Authority. `POST /vuln/attachments/tokens/issue` accepts ledger hashes plus optional metadata, signs the response with the primary Authority key, and records audit trails (`vuln.attachment.token.*`). `POST /vuln/attachments/tokens/verify` validates incoming tokens server-side.

+## Gap-to-Sprint Mapping
+
+### P0 - Critical (Must Implement First)
+
+| Gap ID | Description | Sprint | Rationale |
+|--------|-------------|--------|-----------|
+| **G6** | Monotonicity enforcement | 0338 | Rollback prevention is security-critical; prevents replay attacks |
+| **G7** | Quarantine directory handling | 0338 | Essential for forensic analysis of failed imports |
+
+### P1 - High Priority
+
+| Gap ID | Description | Sprint | Rationale |
+|--------|-------------|--------|-----------|
+| **G4** | CLI `offline` command group | 0339 | Primary operator interface; competitive parity |
+| **G11** | Prometheus metrics | 0341 | Operational visibility in air-gap environments |
+| **G13** | Error reason codes | 0341 | Automation and troubleshooting |
+
+### P2 - Important
+
+| Gap ID | Description | Sprint | Rationale |
+|--------|-------------|--------|-----------|
+| **G5** | Scanner offline config surface | 0340 | Enterprise trust anchor management |
+| **G12** | Structured logging fields | 0341 | Log aggregation and correlation |
+| **G14** | Audit schema enhancement | 0341 | Compliance and chain-of-custody |
+
+### P3 - Lower Priority
+
+| Gap ID | Description | Sprint | Rationale |
+|--------|-------------|--------|-----------|
+| **G10** | Evidence reconciliation algorithm | 0342 | Complex but valuable; VEX-first decisioning |
+
+### Deferred (Not Implementing)
+
+| Gap ID | Description | Rationale |
+|--------|-------------|-----------|
+| **G9** | YAML verification policy schema | Over-engineering; existing JSON/code config sufficient |

+
+## Implementation Sequence
+
+### Phase 1: Foundation (Sprint 0338)
+**Duration:** 1 sprint
+**Focus:** Security-critical infrastructure
+
+1. Implement `BundleVersion` model with semver parsing
+2. Create `IVersionMonotonicityChecker` and Postgres store
+3. Integrate monotonicity check into `ImportValidator`
+4. Implement `--force-activate` with audit trail
+5. Create `IQuarantineService` and file-system implementation
+6. Integrate quarantine into all import failure paths
+7. Write comprehensive tests

+- [ ] Failed bundles are preserved for investigation
+- [ ] Force activation requires justification
+
+### Phase 2: Operator Experience (Sprints 0339, 0341)
+**Duration:** 1-2 sprints (can parallelize)
+**Focus:** CLI and observability
+
+**Sprint 0339 (CLI):**
+1. Create `offline` command group

+2. Implement offline kit metrics
+3. Standardize structured logging fields
+4. Complete error reason codes
+5. Create audit schema migration
+6. Implement audit repository and emitter
+7. Create Grafana dashboard
+
+> Blockers: Prometheus `/metrics` endpoint hosting and audit emitter call-sites await an owning Offline Kit import/activation flow (`POST /api/offline-kit/import`).
+
+**Exit Criteria:**
+- [ ] Operators can import/verify kits via CLI
+- [ ] Metrics are visible in Prometheus/Grafana
+- [ ] All operations are auditable
+
+### Phase 3: Configuration (Sprint 0340)
+**Duration:** 1 sprint
+**Focus:** Trust anchor management
+
+1. Create `OfflineKitOptions` configuration class
+2. Implement PURL pattern matcher
+3. Create `TrustAnchorRegistry` with precedence resolution
+4. Add options validation
+5. Integrate trust anchors with DSSE verification
+6. Update Helm chart values
+7. Write configuration tests
+
+**Exit Criteria:**
+- [ ] Trust anchors configurable per ecosystem
+- [ ] DSSE verification uses configured anchors
+- [ ] Invalid configuration fails startup
+
+### Phase 4: Advanced Features (Sprint 0342)
+**Duration:** 1-2 sprints
+**Focus:** Evidence reconciliation
+
+1. Design artifact indexing
+2. Implement evidence collection
+3. Create document normalization
+4. Implement VEX precedence lattice
+5. Create evidence graph emitter
+6. Integrate with CLI `verify offline`
+7. Write golden-file determinism tests
+
+**Exit Criteria:**
+- [ ] Evidence reconciliation is deterministic
+- [ ] VEX conflicts resolved by precedence
+- [ ] Graph output is signed and verifiable
+
+---
+
+## Testing Strategy
+
+### Unit Tests
+- All new classes have corresponding test classes
+- Mock dependencies for isolation
+- Property-based tests for lattice operations
+
+### Integration Tests
+- Testcontainers for PostgreSQL
+- Full import → verification → audit flow
+- CLI command execution tests
+
+### Determinism Tests
+- Golden-file tests for evidence reconciliation
+- Cross-platform validation (Windows, Linux, macOS)
+- Reproducibility across runs
+
+### Security Tests
+- Monotonicity bypass attempts
+- Signature verification edge cases

+# EPSS Air-Gapped Bundles Guide
+
+## Overview
+
+This guide describes how to create, distribute, and import EPSS (Exploit Prediction Scoring System) data bundles for air-gapped StellaOps deployments. EPSS bundles enable offline vulnerability risk scoring with the same probabilistic threat intelligence available to online deployments.
+
+**Key Concepts**:
+- **Risk Bundle**: Aggregated security data (EPSS + KEV + advisories) for offline import
+- **EPSS Snapshot**: Single-day EPSS scores for all CVEs (~300k rows)
+- **Staleness Threshold**: How old EPSS data can be before fallback to CVSS-only
+- **Deterministic Import**: Same bundle imported twice yields identical database state
+

+## Creating EPSS Bundles
+
+### Prerequisites
+
+**Build System Requirements**:
+- Internet access (for fetching FIRST.org data)
+- StellaOps Bundler CLI: `stellaops-bundler`
+- ZSTD compression: `zstd` (v1.5+)
+- Python 3.10+ (for verification scripts)
+
+**Permissions**:
+- Read access to FIRST.org EPSS API/CSV endpoints
+- Write access to bundle staging directory
+- (Optional) Signing key for DSSE signatures
+
+### Daily Bundle Creation (Automated)
+
+**Recommended Schedule**: Daily at 01:00 UTC (after FIRST publishes at ~00:00 UTC)
+
+**Script**: `scripts/create-risk-bundle.sh`
+
+```bash
+#!/bin/bash
+set -euo pipefail
+

+```
+
+---
+
+## Distributing Bundles
+
+### Transfer Methods
+
+#### 1. Physical Media (Highest Security)
+
+```bash
+# Copy to USB drive
+cp /var/stellaops/bundles/risk-bundle-2025-12-17.tar.gz /media/usb/stellaops/
+
+# Verify checksum
+sha256sum /media/usb/stellaops/risk-bundle-2025-12-17.tar.gz
+```
+
+#### 2. Secure File Transfer (Network Isolation)
+
+```bash
+# SCP over dedicated management network
+scp /var/stellaops/bundles/risk-bundle-2025-12-17.tar.gz \
+  admin@airgap-gateway.internal:/incoming/
+
+# Verify after transfer
+ssh admin@airgap-gateway.internal \
+  "sha256sum /incoming/risk-bundle-2025-12-17.tar.gz"
+```
+
+#### 3. Offline Bundle Repository (CD/DVD)
+
+```bash
+# Burn to CD/DVD (for regulated industries)
+growisofs -Z /dev/sr0 \
+  -R -J -joliet-long \
+  -V "StellaOps Risk Bundle 2025-12-17" \
+  /var/stellaops/bundles/risk-bundle-2025-12-17.tar.gz
+
+# Verify disc
+md5sum /dev/sr0 > risk-bundle-2025-12-17.md5
+```
+
+### Storage Recommendations
+
+**Bundle Retention**:
+- **Online bundler**: Keep last 90 days (rolling cleanup)
+- **Air-gapped system**: Keep last 30 days minimum (for rollback)
+
+**Naming Convention**:
+- Pattern: `risk-bundle-YYYY-MM-DD.tar.gz`
+- Example: `risk-bundle-2025-12-17.tar.gz`
+
+**Directory Structure** (air-gapped system):
+```
+/opt/stellaops/bundles/
+├── incoming/               # Transfer staging area
+├── verified/               # Verified, ready to import
+├── imported/               # Successfully imported (archive)
+└── failed/                 # Failed verification/import (quarantine)
+```
+
+---
+
+## Importing Bundles (Air-Gapped System)
+
+### Pre-Import Verification
+
+**Step 1: Transfer to Verified Directory**
+
+```bash
+# Transfer from incoming to verified (manual approval gate)
+sudo mv /opt/stellaops/bundles/incoming/risk-bundle-2025-12-17.tar.gz \
+        /opt/stellaops/bundles/verified/
+```
+
+**Step 2: Verify Bundle Integrity**
+
+```bash
+# Extract bundle
+cd /opt/stellaops/bundles/verified
+tar -xzf risk-bundle-2025-12-17.tar.gz
+
+# Verify checksums
+cd risk-bundle-2025-12-17
+sha256sum -c signatures/bundle.sha256sums
+
+# Expected output:
+# epss/epss_scores-2025-12-17.csv.zst: OK
+# epss/epss_metadata.json: OK
+# kev/kev-catalog.json: OK
+# manifest.json: OK
+```
+
+**Step 3: Verify DSSE Signature (if signed)**
+
+```bash
+stellaops-bundler verify-signature \
+  --manifest manifest.json \
+  --signature signatures/bundle.dsse.json \
+  --trusted-keys /etc/stellaops/trusted-keys.json
+
+# Expected output:
+# ✓ Signature valid
+# ✓ Key ID: stellaops-bundler-2025
+# ✓ Signed at: 2025-12-17T01:05:00Z
+```
+
+### Import Procedure
+
+**Step 4: Import Bundle**
+
+```bash
+# Import using stellaops CLI
+stellaops offline import \
+  --bundle /opt/stellaops/bundles/verified/risk-bundle-2025-12-17.tar.gz \
+  --verify \
+  --dry-run
+
+# Review dry-run output, then execute
+stellaops offline import \
+  --bundle /opt/stellaops/bundles/verified/risk-bundle-2025-12-17.tar.gz \
+  --verify
+```
+
+**Import Output**:
+```
+Importing risk bundle: risk-bundle-2025-12-17
+  ✓ Manifest validated
+  ✓ Checksums verified
+  ✓ Signature verified
+
+Importing EPSS data...
+  Model Date: 2025-12-17

+  ✓ epss_current upserted (231,417 rows, 5.2s)
+  ✓ Event emitted: epss.updated
+
+Importing KEV catalog...
+  Known Exploited Count: 1,247
+  ✓ kev_catalog updated
+
+Import completed successfully in 41.2s
+```
+
+**Step 5: Verify Import**
+
+```bash
+# Check EPSS status
+stellaops epss status
+
+# Expected output:
+# EPSS Status:
+#   Latest Model Date: 2025-12-17
+#   Source: bundle://risk-bundle-2025-12-17
+#   CVE Count: 231,417
+#   Staleness: FRESH (0 days)
+#   Import Time: 2025-12-17T10:30:00Z
+
+# Query specific CVE to verify
+stellaops epss get CVE-2024-12345
+
+# Expected output:
+# CVE-2024-12345
+#   Score: 0.42357
+#   Percentile: 88.2th
+#   Model Date: 2025-12-17
+#   Source: bundle://risk-bundle-2025-12-17
+```
+
+**Step 6: Archive Imported Bundle**
+
+```bash
+# Move to imported archive
+sudo mv /opt/stellaops/bundles/verified/risk-bundle-2025-12-17.tar.gz \
+        /opt/stellaops/bundles/imported/

+## Staleness Handling
+
+### Staleness Thresholds
+
+| Days Since Model Date | Status | Action |
+|-----------------------|--------|--------|
+| 0-1 | FRESH | Normal operation |
+| 2-7 | ACCEPTABLE | Continue, low-priority alert |
+| 8-14 | STALE | Alert, plan bundle import |
+| 15+ | VERY_STALE | Fallback to CVSS-only, urgent alert |
+
+### Monitoring Staleness
+
+**SQL Query**:
+```sql
+SELECT * FROM concelier.epss_model_staleness;
+
+-- Output:
+-- latest_model_date | latest_import_at       | days_stale | staleness_status
+-- 2025-12-10        | 2025-12-10 10:30:00+00 | 7          | ACCEPTABLE
+```
+
+**Prometheus Metric**:
+```promql
+epss_model_staleness_days{instance="airgap-prod"}
+
+# Alert rule:
+- alert: EpssDataStale
+  expr: epss_model_staleness_days > 7
+  for: 1h
+  labels:
+    severity: warning
+  annotations:
+    summary: "EPSS data is stale ({{ $value }} days old)"
+```
+
+### Fallback Behavior
+
+When EPSS data is VERY_STALE (>14 days):
+
+**Automatic Fallback**:
+- Scanner: Skip EPSS evidence, log warning
+- Policy: Use CVSS-only scoring (no EPSS bonus)
+- Notifications: Disabled EPSS-based alerts
+- UI: Show staleness banner, disable EPSS filters
+
+**Manual Override** (force continue using stale data):
+```yaml
+# etc/scanner.yaml
+scanner:
+  epss:
+    staleness_policy: continue  # Options: fallback, continue, error
+    max_staleness_days: 30      # Override 14-day default
+```
+
+---
+
+## Troubleshooting
+
+### Bundle Import Failed: Checksum Mismatch
+
+**Symptom**:
+```
+ERROR: Checksum verification failed
+epss/epss_scores-2025-12-17.csv.zst: FAILED
+```
+
+**Diagnosis**:
+1. Verify bundle was not corrupted during transfer:
+   ```bash
+   # Compare with original
+   sha256sum risk-bundle-2025-12-17.tar.gz
+   ```
+
+2. Re-transfer bundle from source
+
+**Resolution**:
+- Delete corrupted bundle: `rm risk-bundle-2025-12-17.tar.gz`
+- Re-download/re-transfer from bundler system
+
+### Bundle Import Failed: Signature Invalid
+
+**Symptom**:
+```
+ERROR: Signature verification failed
+Invalid signature or untrusted key
+```
+
+**Diagnosis**:
+1. Check trusted keys configured:
+   ```bash
+   cat /etc/stellaops/trusted-keys.json
+   ```
+
+2. Verify key ID in bundle signature matches:
+   ```bash
+   jq '.signature.key_id' manifest.json
+   ```
+
+**Resolution**:
+- Update trusted keys file with current bundler public key
+- Or: Skip signature verification (if signatures optional):
+  ```bash
+  stellaops offline import --bundle risk-bundle-2025-12-17.tar.gz --skip-signature-verify
+  ```
+
+### No EPSS Data After Import
+
+**Symptom**:
+- Import succeeded, but `stellaops epss status` shows "No EPSS data"
+
+**Diagnosis**:
+```sql
+-- Check import runs
+SELECT * FROM concelier.epss_import_runs ORDER BY created_at DESC LIMIT 1;
+
+-- Check epss_current count
+SELECT COUNT(*) FROM concelier.epss_current;
+```
+
+**Resolution**:
+1. If import_runs shows FAILED status:
+   - Check error column: `SELECT error FROM concelier.epss_import_runs WHERE status = 'FAILED'`
+   - Re-run import with verbose logging
+
+2. If epss_current is empty:
+   - Manually trigger upsert:
+     ```sql
+     -- Re-run upsert for latest model_date
+     -- (This SQL is safe to re-run)
+     INSERT INTO concelier.epss_current (cve_id, epss_score, percentile, model_date, import_run_id, updated_at)
+     SELECT s.cve_id, s.epss_score, s.percentile, s.model_date, s.import_run_id, NOW()
+     FROM concelier.epss_scores s
+     WHERE s.model_date = (SELECT MAX(model_date) FROM concelier.epss_import_runs WHERE status = 'SUCCEEDED')
+     ON CONFLICT (cve_id) DO UPDATE SET
+       epss_score = EXCLUDED.epss_score,
+       percentile = EXCLUDED.percentile,
+       model_date = EXCLUDED.model_date,
+       import_run_id = EXCLUDED.import_run_id,
+       updated_at = NOW();
+     ```

+
+## Best Practices
+
+### 1. Weekly Bundle Import Cadence
+
+**Recommended Schedule**:
+- **Minimum**: Weekly (every Monday)
+- **Preferred**: Bi-weekly (Monday & Thursday)
+- **Ideal**: Daily (if transfer logistics allow)
+
+### 2. Bundle Verification Checklist
+
+Before importing:
+- [ ] Checksum verification passed
+- [ ] Signature verification passed (if signed)
+- [ ] Model date within acceptable staleness window
+- [ ] Disk space available (estimate: 500MB per bundle)
+- [ ] Backup current EPSS data (for rollback)
+
+### 3. Rollback Plan
+
+If new bundle causes issues:
+```bash
+# 1. Identify problematic import_run_id
+SELECT import_run_id, model_date, status
+FROM concelier.epss_import_runs
+ORDER BY created_at DESC LIMIT 5;
+
+# 2. Delete problematic import (cascades to epss_scores, epss_changes)
+DELETE FROM concelier.epss_import_runs
+WHERE import_run_id = '550e8400-...';
+
+# 3. Restore epss_current from previous day
+-- (Upsert from previous model_date as shown in troubleshooting)
+
+# 4. Verify rollback
+stellaops epss status
+```
+
+### 4. Audit Trail
+
+Log all bundle imports for compliance:
+
+**Audit Log Format** (`/var/log/stellaops/bundle-audit.log`):
+```json
+{
+  "timestamp": "2025-12-17T10:30:00Z",
+  "action": "import",
+  "bundle_id": "risk-bundle-2025-12-17",
+  "bundle_sha256": "abc123...",
+  "imported_by": "admin@example.com",
+  "import_run_id": "550e8400-e29b-41d4-a716-446655440000",
+  "result": "SUCCESS",
+  "row_count": 231417,
+  "duration_seconds": 41.2
+}
+```

+# Offline Bundle Format (.stella.bundle.tgz)
+
+> Sprint: SPRINT_3603_0001_0001  
+> Module: ExportCenter
+
+This document describes the `.stella.bundle.tgz` format for portable, signed, verifiable evidence packages.
+
+## Overview
+
+The offline bundle is a self-contained archive containing all evidence and artifacts needed for offline triage of security findings. Bundles are:
+
+- **Portable**: Single file that can be transferred to air-gapped environments
+- **Signed**: DSSE-signed manifest for authenticity verification
+- **Verifiable**: Content-addressable with SHA-256 hashes for integrity
+- **Complete**: Contains all data needed for offline decision-making
+

+  "content_type": "application/json",
+  "compression": null
+}
+```
+
+## DSSE Signing
+
+Bundles support DSSE (Dead Simple Signing Envelope) signing:

+    }
+  ]
+}
+```
+
+## Creation
+
+### API Endpoint
+
+```http
+GET /v1/alerts/{alertId}/bundle
+Authorization: Bearer <token>
+
+Response: application/gzip
+Content-Disposition: attachment; filename="alert-123.stella.bundle.tgz"
+```
+
+### Programmatic
+
+```csharp
+var packager = services.GetRequiredService<IOfflineBundlePackager>();
+
+var result = await packager.CreateBundleAsync(new BundleRequest
+{
+    AlertId = "alert-123",
+    ActorId = "user@example.com",
+    IncludeVexHistory = true,
+    IncludeSbomSlice = true
+});
+
+// result.Content contains the tarball stream
+// result.ManifestHash contains the verification hash
+```
+
+## Verification
+
+### API Endpoint
+
+```http
+POST /v1/alerts/{alertId}/bundle/verify
+Content-Type: application/json
+
+{
+  "bundle_hash": "sha256:abc123...",
+  "signature": "<optional DSSE signature>"
+}
+
+Response:
+{
+  "is_valid": true,
+  "hash_valid": true,
+  "chain_valid": true,
+  "signature_valid": true,
+  "verified_at": "2024-12-15T10:00:00Z"
+}
+```
+
+### Programmatic
+
+```csharp
+var verification = await packager.VerifyBundleAsync(
+    bundlePath: "/path/to/bundle.stella.bundle.tgz",
+    expectedHash: "sha256:abc123...");
+
+if (!verification.IsValid)
+{
+    Console.WriteLine($"Verification failed: {string.Join(", ", verification.Errors)}");
+}
+```
+
+## CLI Usage
+
+```bash
+# Export bundle
+stellaops alert bundle export --alert-id alert-123 --output ./bundles/
+
+# Verify bundle
+stellaops alert bundle verify --file ./bundles/alert-123.stella.bundle.tgz
+
+# Import bundle (air-gapped instance)
+stellaops alert bundle import --file ./bundles/alert-123.stella.bundle.tgz
+```
+
+## Security Considerations
+
+1. **Hash Verification**: Always verify bundle hash before processing
+2. **Signature Validation**: Verify DSSE signature if present
+3. **Content Validation**: Validate JSON schemas after extraction
+4. **Size Limits**: Enforce maximum bundle size limits (default: 100MB)
+5. **Path Traversal**: Tarball extraction must prevent path traversal attacks
+
+## Versioning

+# Offline Parity Verification
+
+**Last Updated:** 2025-12-14
+**Next Review:** 2026-03-14
+
+---
+
+## Overview
+
+This document defines the methodology for verifying that StellaOps scanner produces **identical results** in offline/air-gapped environments compared to connected deployments. Parity verification ensures that security decisions made in disconnected environments are equivalent to those made with full network access.
+
+---
+
+## 1. PARITY VERIFICATION OBJECTIVES
+
+### 1.1 Core Guarantees
+
+| Guarantee | Description | Target |
+|-----------|-------------|--------|
+| **Bitwise Fidelity** | Scan outputs are byte-identical offline vs online | 100% |
+| **Semantic Fidelity** | Same vulnerabilities, severities, and verdicts | 100% |
+| **Temporal Parity** | Same results given identical feed snapshots | 100% |
+| **Policy Parity** | Same pass/fail decisions with identical policies | 100% |
+
+### 1.2 What Parity Does NOT Cover
+
+- **Feed freshness**: Offline feeds may be hours/days behind live feeds (by design)
+- **Network-only enrichment**: EPSS lookups, live KEV checks (graceful degradation applies)
+- **Transparency log submission**: Rekor entries created only when connected
+
+---
+
+## 2. TEST METHODOLOGY
+
+### 2.1 Environment Configuration
+
+#### Connected Environment
+
+```yaml
+environment:
+  mode: connected
+  network: enabled
+  feeds:
+    sources: [osv, ghsa, nvd]
+    refresh: live
+  rekor: enabled
+  epss: enabled
+  timestamp_source: ntp
+```
+
+#### Offline Environment
+
+```yaml
+environment:
+  mode: offline
+  network: disabled
+  feeds:
+    sources: [local-bundle]
+    refresh: none
+  rekor: offline-snapshot
+  epss: bundled-cache
+  timestamp_source: frozen
+  timestamp_value: "2025-12-14T00:00:00Z"
+```
+
+### 2.2 Test Procedure
+
+```
+PARITY VERIFICATION PROCEDURE v1.0
+══════════════════════════════════
+
+PHASE 1: BUNDLE CAPTURE (Connected Environment)
+─────────────────────────────────────────────────
+1. Capture current feed state:
+   - Record feed version/digest
+   - Snapshot EPSS scores (top 1000 CVEs)
+   - Record KEV list state
+
+2. Run connected scan:
+   stellaops scan --image <test-image> \
+     --format json \
+     --output connected-scan.json \
+     --receipt connected-receipt.json
+
+3. Export offline bundle:
+   stellaops offline bundle export \
+     --feeds-snapshot \
+     --epss-cache \
+     --output parity-bundle-$(date +%Y%m%d).tar.zst
+
+PHASE 2: OFFLINE SCAN (Air-Gapped Environment)
+───────────────────────────────────────────────
+1. Import bundle:
+   stellaops offline bundle import parity-bundle-*.tar.zst
+
+2. Freeze clock to bundle timestamp:
+   export STELLAOPS_DETERMINISM_TIMESTAMP="2025-12-14T00:00:00Z"
+
+3. Run offline scan:
+   stellaops scan --image <test-image> \
+     --format json \
+     --output offline-scan.json \
+     --receipt offline-receipt.json \
+     --offline-mode
+
+PHASE 3: PARITY COMPARISON
+──────────────────────────
+1. Compare findings digests:
+   diff <(jq -S '.findings | sort_by(.id)' connected-scan.json) \
+        <(jq -S '.findings | sort_by(.id)' offline-scan.json)
+
+2. Compare policy decisions:
+   diff <(jq -S '.policyDecision' connected-scan.json) \
+        <(jq -S '.policyDecision' offline-scan.json)
+
+3. Compare receipt input hashes:
+   jq '.inputHash' connected-receipt.json
+   jq '.inputHash' offline-receipt.json
+   # MUST be identical if same bundle used
+
+PHASE 4: RECORD RESULTS
+───────────────────────
+1. Generate parity report:
+   stellaops parity report \
+     --connected connected-scan.json \
+     --offline offline-scan.json \
+     --output parity-report-$(date +%Y%m%d).json
+```
+
+### 2.3 Test Image Matrix
+
+Run parity tests against this representative image set:
+
+| Image | Category | Expected Vulns | Notes |
+|-------|----------|----------------|-------|
+| `alpine:3.19` | Minimal | ~5 | Fast baseline |
+| `debian:12-slim` | Standard | ~40 | OS package focus |
+| `node:20-alpine` | Application | ~100 | npm + OS packages |
+| `python:3.12` | Application | ~150 | pip + OS packages |
+| `dotnet/aspnet:8.0` | Application | ~75 | NuGet + OS packages |
+| `postgres:16-alpine` | Database | ~70 | Database + OS |
+
+---
+
+## 3. COMPARISON CRITERIA
+
+### 3.1 Bitwise Comparison
+
+Compare canonical JSON outputs after normalization:
+
+```bash
+# Canonical comparison script
+canonical_compare() {
+    local connected="$1"
+    local offline="$2"
+
+    # Normalize both outputs
+    jq -S . "$connected" > /tmp/connected-canonical.json
+    jq -S . "$offline" > /tmp/offline-canonical.json
+
+    # Compute hashes
+    CONNECTED_HASH=$(sha256sum /tmp/connected-canonical.json | cut -d' ' -f1)
+    OFFLINE_HASH=$(sha256sum /tmp/offline-canonical.json | cut -d' ' -f1)
+
+    if [[ "$CONNECTED_HASH" == "$OFFLINE_HASH" ]]; then
+        echo "PASS: Bitwise identical"
+        return 0
+    else
+        echo "FAIL: Hash mismatch"
+        echo "  Connected: $CONNECTED_HASH"
+        echo "  Offline:   $OFFLINE_HASH"
+        diff --color /tmp/connected-canonical.json /tmp/offline-canonical.json
+        return 1
+    fi
+}
+```
+
+### 3.2 Semantic Comparison
+
+When bitwise comparison fails, perform semantic comparison:
+
+| Field | Comparison Rule | Allowed Variance |
+|-------|-----------------|------------------|
+| `findings[].id` | Exact match | None |
+| `findings[].severity` | Exact match | None |
+| `findings[].cvss.score` | Exact match | None |
+| `findings[].cvss.vector` | Exact match | None |
+| `findings[].affected` | Exact match | None |
+| `findings[].reachability` | Exact match | None |
+| `sbom.components[].purl` | Exact match | None |
+| `sbom.components[].version` | Exact match | None |
+| `metadata.timestamp` | Ignored | Expected to differ |
+| `metadata.scanId` | Ignored | Expected to differ |
+| `metadata.environment` | Ignored | Expected to differ |
+
+### 3.3 Fields Excluded from Comparison
+
+These fields are expected to differ and are excluded from parity checks:
+
+```json
+{
+  "excludedFields": [
+    "$.metadata.scanId",
+    "$.metadata.timestamp",
+    "$.metadata.hostname",
+    "$.metadata.environment.network",
+    "$.attestations[*].rekorEntry",
+    "$.metadata.epssEnrichedAt"
+  ]
+}
+```
+
+### 3.4 Graceful Degradation Fields
+
+Fields that may be absent in offline mode (acceptable):
+
+| Field | Online | Offline | Parity Rule |
+|-------|--------|---------|-------------|
+| `epssScore` | Present | May be stale/absent | Check if bundled |
+| `kevStatus` | Live | Bundled snapshot | Compare against bundle date |
+| `rekorEntry` | Present | Absent | Exclude from comparison |
+| `fulcioChain` | Present | Absent | Exclude from comparison |

+
+## 6. KNOWN LIMITATIONS
+
+### 6.1 Acceptable Differences
+
+| Scenario | Expected Behavior | Parity Impact |
+|----------|-------------------|---------------|
+| **EPSS scores** | Use bundled cache (may be stale) | None if cache bundled |
+| **KEV status** | Use bundled snapshot | None if snapshot bundled |
+| **Rekor entries** | Not created offline | Excluded from comparison |
+| **Timestamp fields** | Differ by design | Excluded from comparison |
+| **Network-only advisories** | Not available offline | Feed drift (documented) |
+
+### 6.2 Known Edge Cases
+
+1. **Race conditions during bundle capture**: If feeds update during bundle export, connected scan may include newer data than bundle. Mitigation: Capture bundle first, then run connected scan.
+
+2. **Clock drift**: Offline environments with drifted clocks may compute different freshness scores. Mitigation: Always use frozen timestamps from bundle.
+
+3. **Locale differences**: String sorting may differ across locales. Mitigation: Force `LC_ALL=C` in both environments.
+
+4. **Floating point rounding**: CVSS v4 MacroVector interpolation may have micro-differences. Mitigation: Use integer basis points throughout.
+
+### 6.3 Out of Scope
+
+The following are intentionally NOT covered by parity verification:
+
+- Real-time threat intelligence (requires network)
+- Live vulnerability disclosure (requires network)
+- Transparency log inclusion proofs (requires Rekor)
+- OIDC/Fulcio certificate chains (requires network)
+

+
+## 7. TROUBLESHOOTING
+
+### 7.1 Common Parity Failures
+
+| Symptom | Likely Cause | Resolution |
+|---------|--------------|------------|
+| Different vulnerability counts | Feed version mismatch | Verify bundle digest matches |
+| Different CVSS scores | CVSS v4 calculation issue | Check MacroVector lookup parity |
+| Different severity labels | Threshold configuration | Compare policy bundles |
+| Missing EPSS data | EPSS cache not bundled | Re-export with `--epss-cache` |
+| Different component counts | SBOM generation variance | Check analyzer versions |
+
+### 7.2 Debug Commands

+# Proof Chain Verification in Air-Gap Mode
+
+> **Version**: 1.0.0  
+> **Last Updated**: 2025-12-17  
+> **Related**: [Proof Chain API](../api/proofs.md), [Key Rotation Runbook](../operations/key-rotation-runbook.md)
+
+This document describes how to verify proof chains in air-gapped (offline) environments where Rekor transparency log access is unavailable.
+
+---
+
+## Overview
+
+Proof chains in StellaOps consist of cryptographically-linked attestations:
+1. **Evidence statements** - Raw vulnerability findings
+2. **Reasoning statements** - Policy evaluation traces
+3. **VEX verdict statements** - Final vulnerability status determinations
+4. **Proof spine** - Merkle tree aggregating all components
+
+In online mode, proof chains include Rekor inclusion proofs for transparency. In air-gap mode, verification proceeds without Rekor but maintains cryptographic integrity.
+
+---
+
+## Verification Levels
+
+### Level 1: Content-Addressed ID Verification
+Verifies that content-addressed IDs match payload hashes.
+
+```bash
+# Verify a proof bundle ID
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --level content-id
+
+# Expected output:
+# ✓ Content-addressed ID verified
+# ✓ Payload hash: sha256:1a2b3c4d...
+```
+
+### Level 2: DSSE Signature Verification
+Verifies DSSE envelope signatures against trust anchors.
+
+```bash
+# Verify signatures with local trust anchors
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --anchor-file /path/to/trust-anchors.json \
+  --level signature
+
+# Expected output:
+# ✓ DSSE signature valid
+# ✓ Signer: key-2025-prod
+# ✓ Trust anchor: 550e8400-e29b-41d4-a716-446655440000
+```
+
+### Level 3: Merkle Path Verification
+Verifies the proof spine merkle tree structure.
+
+```bash
+# Verify merkle paths
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --level merkle
+
+# Expected output:
+# ✓ Merkle root verified
+# ✓ Evidence paths: 3/3 valid
+# ✓ Reasoning path: valid
+# ✓ VEX verdict path: valid
+```
+
+### Level 4: Full Verification (Offline)
+Performs all verification steps except Rekor.
+
+```bash
+# Full offline verification
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --anchor-file /path/to/trust-anchors.json
+
+# Expected output:
+# Proof Chain Verification
+# ═══════════════════════
+# ✓ Content-addressed IDs verified
+# ✓ DSSE signatures verified (3 envelopes)
+# ✓ Merkle paths verified
+# ⊘ Rekor verification skipped (offline mode)
+# 
+# Overall: VERIFIED (offline)
+```
+
+---
+
+## Trust Anchor Distribution
+
+In air-gap environments, trust anchors must be distributed out-of-band.
+
+### Export Trust Anchors
+
+```bash
+# On the online system, export trust anchors
+stellaops anchor export --format json > trust-anchors.json
+
+# Verify export integrity
+sha256sum trust-anchors.json > trust-anchors.sha256
+```
+
+### Trust Anchor File Format
+
+```json
+{
+  "version": "1.0",
+  "exportedAt": "2025-12-17T00:00:00Z",
+  "anchors": [
+    {
+      "trustAnchorId": "550e8400-e29b-41d4-a716-446655440000",
+      "purlPattern": "pkg:*",

+      "allowedPredicateTypes": [
+        "evidence.stella/v1",
+        "reasoning.stella/v1",

+        },
+        "key-2025-prod": {
+          "algorithm": "ECDSA-P256",
+          "publicKey": "-----BEGIN PUBLIC KEY-----\n..."
+        }
+      }
+    }
+  ]
+}
+```
+
+### Import Trust Anchors
+
+```bash
+# On the air-gapped system
+stellaops anchor import --file trust-anchors.json
+
+# Verify import
+stellaops anchor list
+```
+
+---
+
+## Proof Bundle Distribution
+
+### Export Proof Bundles
+
+```bash
+# Export a proof bundle for offline transfer
+stellaops proof export \
+  --entry sha256:abc123:pkg:npm/lodash@4.17.21 \
+  --output proof-bundle.zip
+
+# Bundle contents:
+# proof-bundle.zip

+# └── VERIFY.md               # Verification instructions
+```
+
+### Verify Exported Bundle
+
+```bash
+# On the air-gapped system
+stellaops proof verify --offline \
+  --bundle-file proof-bundle.zip \
+  --anchor-file trust-anchors.json
+```
+
+---
+
+## Batch Verification
+
+For audits, verify multiple proof bundles efficiently:
+
+```bash
+# Create a verification manifest
+cat > verify-manifest.json << 'EOF'
+{
+  "bundles": [
+    "sha256:1a2b3c4d...",
+    "sha256:5e6f7g8h...",
+    "sha256:9i0j1k2l..."
+  ],
+  "options": {
+    "checkRekor": false,
+    "failFast": false
+  }
+}
+EOF
+
+# Run batch verification
+stellaops proof verify-batch \
+  --manifest verify-manifest.json \
+  --anchor-file trust-anchors.json \
+  --output verification-report.json
+```
+
+### Verification Report Format
+
+```json
+{
+  "verifiedAt": "2025-12-17T10:00:00Z",
+  "mode": "offline",
+  "anchorsUsed": ["550e8400..."],

+    "total": 3,
+    "verified": 3,
+    "failed": 0,
+    "skipped": 0
+  }
+}
+```
+
+---
+
+## Key Rotation in Air-Gap Mode
+
+When keys are rotated, trust anchor updates must be distributed:
+
+### 1. Export Updated Anchors
+
+```bash
+# On online system after key rotation
+stellaops anchor export --since 2025-01-01 > anchor-update.json
+sha256sum anchor-update.json > anchor-update.sha256
+```
+
+### 2. Verify and Import Update
+
+```bash
+# On air-gapped system
+sha256sum -c anchor-update.sha256
+stellaops anchor import --file anchor-update.json --merge
+
+# Verify key history
+stellaops anchor show --anchor-id 550e8400... --show-history
+```
+
+### 3. Temporal Verification
+
+When verifying old proofs after key rotation:
+
+```bash
+# Verify proof signed with now-revoked key
+stellaops proof verify --offline \
+  --proof-bundle sha256:old-proof... \
+  --anchor-file trust-anchors.json \
+  --at-time "2024-06-15T12:00:00Z"
+
+# The verification uses key validity at the specified time
+```
+
+---
+
+## Manual Verification (No CLI)
+
+For environments without the StellaOps CLI, manual verification is possible:
+
+### 1. Verify Content-Addressed ID
+
+```bash
+# Extract payload from DSSE envelope
+jq -r '.payload' proof-spine.dsse | base64 -d > payload.json
+
+# Compute hash
+sha256sum payload.json
+# Compare with proof bundle ID
+```
+
+### 2. Verify DSSE Signature
+
+```python
+#!/usr/bin/env python3
+import json
+import base64
+from cryptography.hazmat.primitives import hashes
+from cryptography.hazmat.primitives.asymmetric import ec
+from cryptography.hazmat.primitives.serialization import load_pem_public_key
+
+def verify_dsse(envelope_path, public_key_pem):
+    """Verify a DSSE envelope signature."""
+    with open(envelope_path) as f:
+        envelope = json.load(f)
+    
+    payload_type = envelope['payloadType']
+    payload = base64.b64decode(envelope['payload'])
+    
+    # Build PAE (Pre-Authentication Encoding)
+    pae = f"DSSEv1 {len(payload_type)} {payload_type} {len(payload)} ".encode() + payload
+    
+    public_key = load_pem_public_key(public_key_pem.encode())
+    
+    for sig in envelope['signatures']:
+        signature = base64.b64decode(sig['sig'])
+        try:
+            public_key.verify(signature, pae, ec.ECDSA(hashes.SHA256()))
+            print(f"✓ Signature valid for keyid: {sig['keyid']}")
+            return True
+        except Exception as e:
+            print(f"✗ Signature invalid: {e}")
+    
+    return False
+```
+
+### 3. Verify Merkle Path
+
+```python
+#!/usr/bin/env python3
+import json
+import hashlib
+
+def verify_merkle_path(leaf_hash, path, root_hash, leaf_index):
+    """Verify a Merkle inclusion path."""
+    current = bytes.fromhex(leaf_hash)
+    index = leaf_index
+    
+    for sibling in path:
+        sibling_bytes = bytes.fromhex(sibling)
+        if index % 2 == 0:
+            # Current is left child
+            combined = current + sibling_bytes
+        else:
+            # Current is right child
+            combined = sibling_bytes + current
+        current = hashlib.sha256(combined).digest()
+        index //= 2
+    
+    computed_root = current.hex()
+    if computed_root == root_hash:
+        print("✓ Merkle path verified")
+        return True
+    else:
+        print(f"✗ Merkle root mismatch: {computed_root} != {root_hash}")
+        return False
+```
+
+---
+
+## Exit Codes
+
+Offline verification uses the same exit codes as online:
+
+| Code | Meaning | CI/CD Action |
+|------|---------|--------------|
+| 0 | Verification passed | Proceed |
+| 1 | Verification failed | Block |
+| 2 | System error | Retry/investigate |
+
+---
+
+## Troubleshooting
+
+### Missing Trust Anchor
+
+```
+Error: No trust anchor found for keyid "key-2025-prod"
+```
+
+**Solution**: Import updated trust anchors from online system.
+
+### Key Not Valid at Time
+
+```
+Error: Key "key-2024-prod" was revoked at 2024-12-01, before proof signature at 2025-01-15
+```
+
+**Solution**: This indicates the proof was signed after key revocation. Investigate the signature timestamp.
+
+### Merkle Path Invalid
+
+```
+Error: Merkle path verification failed for evidence sha256:e1...
+```
+
+**Solution**: The proof bundle may be corrupted. Re-export from online system.

+# AirGap Quarantine Investigation Runbook
+
+## Purpose
+Quarantine preserves failed bundle imports for offline forensic analysis. It keeps the original bundle and the verification context (reason + logs) so operators can diagnose tampering, trust-root drift, or packaging issues without re-running in an online environment.
+
+## Location & Structure
+Default root: `/updates/quarantine`
+
+Per-tenant layout:
+`/updates/quarantine/<tenantId>/<timestamp>-<reason>-<id>/`
+
+Removal staging:
+`/updates/quarantine/<tenantId>/.removed/<quarantineId>/`
+
+## Files in a quarantine entry
+- `bundle.tar.zst` - the original bundle as provided
+- `manifest.json` - bundle manifest (when available)
+- `verification.log` - validation step output (TUF/DSSE/Merkle/rotation/monotonicity, etc.)
+- `failure-reason.txt` - human-readable failure summary (reason + timestamp + metadata)
+- `quarantine.json` - structured metadata for listing/automation
+
+## Investigation steps (offline)
+1. Identify the tenant and locate the quarantine root on the importer host.
+2. Pick the newest quarantine entry for the tenant (timestamp prefix).
+3. Read `failure-reason.txt` first to capture the top-level reason and metadata.
+4. Review `verification.log` for the precise failing step.
+5. If needed, extract and inspect `bundle.tar.zst` in an isolated workspace (no network).
+6. Decide whether the entry should be retained (for audit) or removed after investigation.
+
+## Removal & Retention
+- Removal requires a human-provided reason (audit trail). Implementations should use the quarantine service’s remove operation which moves entries under `.removed/`.
+- Retention and quota controls are configured via `AirGap:Quarantine` settings (root, TTL, max size); TTL cleanup can remove entries older than the retention period.
+
+## Common failure categories
+- `tuf:*` - invalid/expired metadata or snapshot hash mismatch
+- `dsse:*` - signature invalid or trust root mismatch
+- `merkle-*` - payload entry set invalid or empty
+- `rotation:*` - root rotation policy failure (dual approval, no-op rotation, etc.)
+- `version-non-monotonic:*` - rollback prevention triggered (force activation requires a justification)

+# Smart-Diff Air-Gap Workflows
+
+**Sprint:** SPRINT_3500_0001_0001  
+**Task:** SDIFF-MASTER-0006 - Document air-gap workflows for smart-diff
+
+## Overview
+
+Smart-Diff can operate in fully air-gapped environments using offline bundles. This document describes the workflows for running smart-diff analysis without network connectivity.
+
+## Prerequisites
+
+1. **Offline Kit** - Downloaded and verified (`stellaops offline kit download`)
+2. **Feed Snapshots** - Pre-staged vulnerability feeds
+3. **SBOM Cache** - Pre-generated SBOMs for target artifacts
+
+## Workflow 1: Offline Smart-Diff Analysis
+
+### Step 1: Prepare Offline Bundle
+
+On a connected machine:
+
+```bash
+# Download offline kit with feeds
+stellaops offline kit download \
+  --output /path/to/offline-bundle \
+  --include-feeds nvd,osv,epss \
+  --feed-date 2025-01-15
+
+# Include SBOMs for known artifacts
+stellaops offline sbom generate \
+  --artifact registry.example.com/app:v1 \
+  --artifact registry.example.com/app:v2 \
+  --output /path/to/offline-bundle/sboms
+
+# Package for transfer
+stellaops offline kit package \
+  --input /path/to/offline-bundle \
+  --output stellaops-offline-2025-01-15.tar.gz \
+  --sign
+```
+
+### Step 2: Transfer to Air-Gapped Environment
+
+Transfer the bundle using approved media:
+- USB drive (scanned and approved)
+- Optical media (DVD/Blu-ray)
+- Data diode
+
+### Step 3: Import Bundle
+
+On the air-gapped machine:
+
+```bash
+# Verify bundle signature
+stellaops offline kit verify \
+  --input stellaops-offline-2025-01-15.tar.gz \
+  --public-key /path/to/signing-key.pub
+
+# Extract and configure
+stellaops offline kit import \
+  --input stellaops-offline-2025-01-15.tar.gz \
+  --data-dir /opt/stellaops/data
+```
+
+### Step 4: Run Smart-Diff
+
+```bash
+# Set offline mode
+export STELLAOPS_OFFLINE=true
+export STELLAOPS_DATA_DIR=/opt/stellaops/data

+# Run smart-diff
+stellaops smart-diff \
+  --base sbom:app-v1.json \
+  --target sbom:app-v2.json \
+  --output smart-diff-report.json
+```
+
+## Workflow 2: Pre-Computed Smart-Diff Export
+
+For environments where even running analysis tools is restricted.
+
+### Step 1: Prepare Artifacts (Connected Machine)
+
+```bash
+# Generate SBOMs
+stellaops sbom generate --artifact app:v1 --output app-v1-sbom.json
+stellaops sbom generate --artifact app:v2 --output app-v2-sbom.json
+
+# Run smart-diff with full proof bundle
+stellaops smart-diff \
+  --base app-v1-sbom.json \
+  --target app-v2-sbom.json \
+  --output-dir ./smart-diff-export \
+  --include-proofs \
+  --include-evidence \
+  --format bundle
+```
+
+### Step 2: Verify Export Contents
+
+The export bundle contains:
+```
+smart-diff-export/
+├── manifest.json           # Signed manifest
+├── base-sbom.json          # Base SBOM (hash verified)
+├── target-sbom.json        # Target SBOM (hash verified)
+├── diff-results.json       # Smart-diff findings
+├── sarif-report.json       # SARIF formatted output
+├── proofs/
+│   ├── ledger.json         # Proof ledger
+│   └── nodes/              # Individual proof nodes
+├── evidence/
+│   ├── reachability.json   # Reachability evidence
+│   ├── vex-statements.json # VEX statements
+│   └── hardening.json      # Binary hardening data
+└── signature.dsse          # DSSE envelope
+```
+
+### Step 3: Import and Verify (Air-Gapped Machine)
+
+```bash
+# Verify bundle integrity
+stellaops verify-bundle \
+  --input smart-diff-export \
+  --public-key /path/to/trusted-key.pub
+
+# View results
+stellaops smart-diff show \
+  --bundle smart-diff-export \
+  --format table
+```
+
+## Workflow 3: Incremental Feed Updates
+
+### Step 1: Generate Delta Feed
+
+On connected machine:
+
+```bash
+# Generate delta since last sync
+stellaops offline feed delta \
+  --since 2025-01-10 \
+  --output feed-delta-2025-01-15.tar.gz \
+  --sign
+```
+
+### Step 2: Apply Delta (Air-Gapped)
+
+```bash
+# Import delta
+stellaops offline feed apply \
+  --input feed-delta-2025-01-15.tar.gz \
+  --verify
+
+# Trigger score replay for affected scans
+stellaops score replay-all \
+  --trigger feed-update \
+  --dry-run
+```
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `STELLAOPS_OFFLINE` | Enable offline mode | `false` |
+| `STELLAOPS_DATA_DIR` | Local data directory | `~/.stellaops` |
+| `STELLAOPS_FEED_DIR` | Feed snapshot directory | `$DATA_DIR/feeds` |
+| `STELLAOPS_SBOM_CACHE` | SBOM cache directory | `$DATA_DIR/sboms` |
+| `STELLAOPS_SKIP_NETWORK` | Block network requests | `false` |
+| `STELLAOPS_REQUIRE_SIGNATURES` | Require signed data | `true` |
+
+### Config File
+
+```yaml
+# ~/.stellaops/config.yaml
+offline:
+  enabled: true
+  data_dir: /opt/stellaops/data
+  require_signatures: true
+  
+feeds:
+  source: local
+  path: /opt/stellaops/data/feeds
+  
+sbom:
+  cache_dir: /opt/stellaops/data/sboms
+  
+network:
+  allow_list: []  # Empty = no network
+```
+
+## Verification
+
+### Verify Feed Freshness
+
+```bash
+# Check feed dates
+stellaops offline status
+
+# Output:
+# Feed Status (Offline Mode)
+# ─────────────────────────────
+# NVD:  2025-01-15 (2 days old)
+# OSV:  2025-01-15 (2 days old)
+# EPSS: 2025-01-14 (3 days old)
+# KEV:  2025-01-15 (2 days old)
+```
+
+### Verify Proof Integrity
+
+```bash
+# Verify smart-diff proofs
+stellaops smart-diff verify \
+  --input smart-diff-report.json \
+  --proof-bundle ./proofs
+
+# Output:
+# ✓ Manifest hash verified
+# ✓ All proof nodes valid
+# ✓ Root hash matches: sha256:abc123...
+```
+
+## Determinism Guarantees
+
+Offline smart-diff maintains determinism by:
+
+1. **Content-addressed feeds** - Same feed hash = same results
+2. **Frozen timestamps** - All timestamps use manifest creation time
+3. **No network randomness** - No external API calls
+4. **Stable sorting** - Deterministic output ordering
+
+### Reproducibility Test
+
+```bash
+# Run twice and compare
+stellaops smart-diff --base a.json --target b.json --output run1.json
+stellaops smart-diff --base a.json --target b.json --output run2.json
+
+# Compare hashes
+sha256sum run1.json run2.json
+# abc123...  run1.json
+# abc123...  run2.json  (identical)
+```
+
+## Troubleshooting
+
+### Error: Feed not found
+
+```
+Error: Feed 'nvd' not found in offline data directory
+```
+
+**Solution:** Ensure feed was included in offline kit:
+```bash
+stellaops offline kit status
+ls $STELLAOPS_FEED_DIR/nvd/
+```
+
+### Error: Network request blocked
+
+```
+Error: Network request blocked in offline mode: api.osv.dev
+```
+
+**Solution:** This is expected behavior. Ensure all required data is in offline bundle.
+
+### Error: Signature verification failed
+
+```
+Error: Bundle signature verification failed
+```
+
+**Solution:** Ensure correct public key is configured:
+```bash
+stellaops offline kit verify \
+  --input bundle.tar.gz \
+  --public-key /path/to/correct-key.pub
+```

+# Triage Air-Gap Workflows
+
+**Sprint:** SPRINT_3600_0001_0001  
+**Task:** TRI-MASTER-0006 - Document air-gap triage workflows
+
+## Overview
+
+This document describes how to perform vulnerability triage in fully air-gapped environments. The triage workflow supports offline evidence bundles, decision capture, and replay token generation.
+
+## Workflow 1: Offline Triage with Evidence Bundles
+
+### Step 1: Export Evidence Bundle (Connected Machine)
+
+```bash
+# Export triage bundle for specific findings
+stellaops triage export \
+  --scan-id scan-12345678 \
+  --findings CVE-2024-1234,CVE-2024-5678 \
+  --include-evidence \
+  --include-graph \
+  --output triage-bundle.stella.bundle.tgz
+
+# Export entire scan for offline review
+stellaops triage export \
+  --scan-id scan-12345678 \
+  --all-findings \
+  --output full-triage-bundle.stella.bundle.tgz
+```
+
+### Step 2: Bundle Contents
+
+The `.stella.bundle.tgz` archive contains:
+
+```
+triage-bundle.stella.bundle.tgz/
+├── manifest.json           # Signed bundle manifest
+├── findings/
+│   ├── index.json          # Finding list with IDs
+│   ├── CVE-2024-1234.json  # Finding details
+│   └── CVE-2024-5678.json
+├── evidence/
+│   ├── reachability/       # Reachability proofs
+│   ├── callstack/          # Call stack snippets
+│   ├── vex/                # VEX/CSAF statements
+│   └── provenance/         # Provenance data
+├── graph/
+│   ├── nodes.ndjson        # Dependency graph nodes
+│   └── edges.ndjson        # Graph edges
+├── feeds/
+│   └── snapshot.json       # Feed snapshot metadata
+└── signature.dsse          # DSSE envelope
+```
+
+### Step 3: Transfer to Air-Gapped Environment
+
+Transfer using approved methods:
+- USB media (security scanned)
+- Optical media
+- Data diode
+
+### Step 4: Import and Verify
+
+On the air-gapped machine:
+
+```bash
+# Verify bundle integrity
+stellaops triage verify-bundle \
+  --input triage-bundle.stella.bundle.tgz \
+  --public-key /path/to/signing-key.pub
+
+# Import for offline triage
+stellaops triage import \
+  --input triage-bundle.stella.bundle.tgz \
+  --workspace /opt/stellaops/triage
+```
+
+### Step 5: Perform Offline Triage
+
+```bash
+# List findings in bundle
+stellaops triage list \
+  --workspace /opt/stellaops/triage
+
+# View finding with evidence
+stellaops triage show CVE-2024-1234 \
+  --workspace /opt/stellaops/triage \
+  --show-evidence
+
+# Make triage decision
+stellaops triage decide CVE-2024-1234 \
+  --workspace /opt/stellaops/triage \
+  --status not_affected \
+  --justification "Code path is unreachable due to config gating" \
+  --reviewer "security-team"
+```
+
+### Step 6: Export Decisions
+
+```bash
+# Export decisions for sync back
+stellaops triage export-decisions \
+  --workspace /opt/stellaops/triage \
+  --output decisions-2025-01-15.json \
+  --sign
+```
+
+### Step 7: Sync Decisions (Connected Machine)
+
+```bash
+# Import and apply decisions
+stellaops triage import-decisions \
+  --input decisions-2025-01-15.json \
+  --verify \
+  --apply
+```
+
+## Workflow 2: Batch Offline Triage
+
+For high-volume environments.
+
+### Step 1: Export Batch Bundle
+
+```bash
+# Export all untriaged findings
+stellaops triage export-batch \
+  --query "status=untriaged AND priority>=0.7" \
+  --limit 100 \
+  --output batch-triage-2025-01-15.stella.bundle.tgz
+```
+
+### Step 2: Offline Batch Processing
+
+```bash
+# Interactive batch triage
+stellaops triage batch \
+  --workspace /opt/stellaops/triage \
+  --input batch-triage-2025-01-15.stella.bundle.tgz
+
+# Keyboard shortcuts enabled:
+# j/k - Next/Previous finding
+# a   - Accept (affected)
+# n   - Not affected
+# w   - Will not fix
+# f   - False positive
+# u   - Undo last decision
+# q   - Quit (saves progress)
+```
+
+### Step 3: Export and Sync
+
+```bash
+# Export batch decisions
+stellaops triage export-decisions \
+  --workspace /opt/stellaops/triage \
+  --format json \
+  --sign \
+  --output batch-decisions.json
+```
+
+## Workflow 3: Evidence-First Offline Review
+
+### Step 1: Pre-compute Evidence
+
+On connected machine:
+
+```bash
+# Generate evidence for all high-priority findings
+stellaops evidence generate \
+  --scan-id scan-12345678 \
+  --priority-min 0.7 \
+  --output-dir ./evidence-pack
+
+# Include:
+# - Reachability analysis
+# - Call stack traces
+# - VEX lookups
+# - Dependency graph snippets
+```
+
+### Step 2: Package with Findings
+
+```bash
+stellaops triage package \
+  --scan-id scan-12345678 \
+  --evidence-dir ./evidence-pack \
+  --output evidence-triage.stella.bundle.tgz
+```
+
+### Step 3: Offline Review with Evidence
+
+```bash
+# Evidence-first view
+stellaops triage show CVE-2024-1234 \
+  --workspace /opt/stellaops/triage \
+  --evidence-first
+
+# Output:
+# ═══════════════════════════════════════════
+# CVE-2024-1234 · lodash@4.17.20
+# ═══════════════════════════════════════════
+#
+# EVIDENCE SUMMARY
+# ────────────────
+# Reachability: EXECUTED (tier 2/3)
+#   └─ main.js:42 → utils.js:15 → lodash/merge
+#
+# Call Stack:
+#   1. main.js:42    handleRequest()
+#   2. utils.js:15   mergeConfig()
+#   3. lodash:merge  <vulnerable>
+#
+# VEX Status: No statement found
+# EPSS: 0.45 (Medium)
+# KEV: No
+#
+# ─────────────────────────────────────────────
+# Press [a]ffected, [n]ot affected, [s]kip...

+
+## Replay Tokens
+
+Each decision generates a replay token for audit trail:
+
+```bash
+# View replay token
+stellaops triage show-token rt_abc123...
+
+# Output:
+# Replay Token: rt_abc123...
+# ─────────────────────────────
+# Finding: CVE-2024-1234
+# Decision: not_affected
+# Evidence Hash: sha256:xyz789...
+# Feed Snapshot: sha256:abc123...
+# Decided: 2025-01-15T14:30:00Z
+# Reviewer: security-team
+```
+
+### Verify Token
+
+```bash
+stellaops triage verify-token rt_abc123... \
+  --public-key /path/to/key.pub
+
+# ✓ Token signature valid
+# ✓ Evidence hash matches
+# ✓ Feed snapshot verified
+```
+
+## Troubleshooting
+
+### Error: Bundle signature invalid
+
+```
+Error: Bundle signature verification failed
+```
+
+**Solution:** Ensure the correct public key is used:
+```bash
+stellaops triage verify-bundle \
+  --input bundle.tgz \
+  --public-key /path/to/correct-key.pub \
+  --verbose
+```
+
+### Error: Evidence not found
+
+```
+Error: Evidence for CVE-2024-1234 not included in bundle
+```
+
+**Solution:** Re-export with evidence:
+```bash
+stellaops triage export \
+  --scan-id scan-12345678 \
+  --findings CVE-2024-1234 \
+  --include-evidence \
+  --output bundle.tgz
+```
+
+### Error: Decision sync conflict
+
+```
+Error: Finding CVE-2024-1234 has newer decision on server
+```
+
+**Solution:** Review and resolve:
+```bash
+stellaops triage import-decisions \
+  --input decisions.json \
+  --conflict-mode review
+
+# Options: keep-local, keep-server, newest, review
+```

+# Orchestrator · First Signal API
+
+Provides a fast “first meaningful signal” for a run (TTFS), with caching and ETag-based conditional requests.
+
+## Endpoint
+
+`GET /api/v1/orchestrator/runs/{runId}/first-signal`
+
+### Required headers
+- `X-Tenant-Id`: tenant identifier (string)
+
+### Optional headers
+- `If-None-Match`: weak ETag from a previous 200 response (supports multiple values)
+
+## Responses
+
+### 200 OK
+Returns the first signal payload and a weak ETag.
+
+Response headers:
+- `ETag`: weak ETag (for `If-None-Match`)
+- `Cache-Control: private, max-age=60`
+- `Cache-Status: hit|miss`
+- `X-FirstSignal-Source: snapshot|cold_start` (best-effort diagnostics)
+
+Body (`application/json`):
+```json
+{
+  "runId": "aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa",
+  "firstSignal": {
+    "type": "started",
+    "stage": "unknown",
+    "step": null,
+    "message": "Run started",
+    "at": "2025-12-15T12:00:10+00:00",
+    "artifact": { "kind": "run", "range": null }
+  },
+  "summaryEtag": "W/\"...\""
+}
+```
+
+### 204 No Content
+Run exists but no signal is available yet (e.g., run has no jobs).
+
+### 304 Not Modified
+Returned when `If-None-Match` matches the current ETag.
+
+### 404 Not Found
+Run does not exist for the resolved tenant.
+
+### 400 Bad Request
+Missing/invalid tenant header or invalid parameters.
+
+## ETag semantics
+- Weak ETags are computed from a deterministic, canonical hash of the stable signal content.
+- Per-request diagnostics (e.g., cache hit/miss) are intentionally excluded from the ETag material.
+
+## Streaming (SSE)
+The run stream emits `first_signal` events when the signal changes:
+
+`GET /api/v1/orchestrator/stream/runs/{runId}`
+
+Event type:
+- `first_signal`
+
+Payload shape:
+```json
+{
+  "runId": "aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa",
+  "etag": "W/\"...\"",
+  "signal": { "version": "1.0", "signalId": "...", "jobId": "...", "timestamp": "...", "kind": 1, "phase": 6, "scope": { "type": "run", "id": "..." }, "summary": "...", "etaSeconds": null, "lastKnownOutcome": null, "nextActions": null, "diagnostics": { "cacheHit": false, "source": "cold_start", "correlationId": "" } }
+}
+```
+
+## Configuration
+
+`appsettings.json`:

+# Proof Chain API Reference
+
+> **Version**: 1.0.0  
+> **OpenAPI Spec**: [`proofs-openapi.yaml`](./proofs-openapi.yaml)
+
+The Proof Chain API provides endpoints for creating and verifying cryptographic proof bundles that link SBOM entries to vulnerability assessments through attestable DSSE envelopes.
+
+---
+
+## Overview
+
+The proof chain creates an auditable, cryptographically-verifiable trail from vulnerability evidence through policy reasoning to VEX verdicts. Each component is signed with DSSE envelopes and aggregated into a merkle-rooted proof spine.
+
+### Proof Chain Components
+
+| Component | Predicate Type | Purpose |
+|-----------|----------------|---------|
+| **Evidence** | `evidence.stella/v1` | Raw findings from scanners/feeds |
+| **Reasoning** | `reasoning.stella/v1` | Policy evaluation trace |
+| **VEX Verdict** | `cdx-vex.stella/v1` | Final VEX status determination |
+| **Proof Spine** | `proofspine.stella/v1` | Merkle aggregation of all components |
+| **Verdict Receipt** | `verdict.stella/v1` | Human-readable verification receipt |
+
+### Content-Addressed IDs
+
+All proof chain components use content-addressed identifiers:
+
+```
+Format: sha256:<64-hex-chars>
+Example: sha256:e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6...
+```
+
+IDs are computed by:
+1. Canonicalizing the JSON payload (RFC 8785/JCS)
+2. Computing SHA-256 hash
+3. Prefixing with `sha256:`
+
+---
+
+## Authentication
+
+All endpoints require authentication via:
+
+- **Bearer Token**: Authority-issued OpToken with appropriate scopes
+- **mTLS**: Mutual TLS with client certificate (service-to-service)
+
+Required scopes:
+- `proofs.read` - Read proof bundles and receipts
+- `proofs.write` - Create proof spines
+- `anchors.manage` - Manage trust anchors
+- `proofs.verify` - Perform verification
+
+---
+
+## Endpoints

+```
+
+---
+
+## Error Handling
+
+All errors follow RFC 7807 Problem Details format:
+
+```json
+{
+  "title": "Validation Error",
+  "detail": "Evidence ID sha256:abc... not found",
+  "status": 422,
+  "errors": {
+    "evidenceIds[0]": ["Evidence not found"]
+  }
+}
+```
+
+### Common Error Codes
+
+| Status | Meaning |
+|--------|---------|
+| 400 | Invalid request format or parameters |
+| 401 | Authentication required |
+| 403 | Insufficient permissions |
+| 404 | Resource not found |
+| 409 | Conflict (e.g., anchor already exists) |
+| 422 | Validation error |
+| 500 | Internal server error |
+
+---
+
+## Offline Verification
+
+For air-gapped environments, verification can be performed without Rekor:
+
+```json
+{
+  "proofBundleId": "sha256:1a2b3c4d...",
+  "checkRekor": false
+}
+```
+
+This skips Rekor inclusion proof verification but still performs:
+- DSSE signature verification
+- Content-addressed ID recomputation
+- Merkle path verification

+# Scanner WebService API — Score Proofs & Reachability Extensions
+
+**Version**: 2.0
+**Base URL**: `/api/v1/scanner`
+**Authentication**: Bearer token (OpTok with DPoP/mTLS)
+**Sprint**: SPRINT_3500_0002_0003, SPRINT_3500_0003_0003
+
+---
+
+## Overview
+
+This document specifies API extensions to `Scanner.WebService` for:
+1. Scan manifests and deterministic replay
+2. Proof bundles (score proofs + reachability evidence)
+3. Call-graph ingestion and reachability analysis
+4. Unknowns management
+
+**Design Principles**:
+- All endpoints return canonical JSON (deterministic serialization)
+- Idempotency via `Content-Digest` headers (SHA-256)
+- DSSE signatures returned for all proof artifacts
+- Offline-first (bundles downloadable for air-gap verification)
+
+---

+# Score Replay API Reference
+
+**Sprint:** SPRINT_3401_0002_0001  
+**Task:** SCORE-REPLAY-014 - Update scanner API docs with replay endpoint
+
+## Overview
+
+The Score Replay API enables deterministic re-scoring of scans using historical manifests. This is essential for auditing, compliance verification, and investigating how scores change with updated advisory feeds.
+
+## Base URL
+
+```
+/api/v1/score
+```
+
+## Authentication
+
+All endpoints require Bearer token authentication:
+
+```http
+Authorization: Bearer <token>
+```
+
+Required scope: `scanner:replay:read` for GET, `scanner:replay:write` for POST
+
+## Endpoints
+
+### Replay Score
+
+```http
+POST /api/v1/score/replay
+```
+
+Re-scores a scan using the original manifest with an optionally different feed snapshot.
+
+#### Request Body
+
+```json
+{
+  "scanId": "scan-12345678-abcd",
+  "feedSnapshotHash": "sha256:abc123...",

+  "dryRun": false
+}
+```
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `scanId` | string | Yes | Original scan ID to replay |
+| `feedSnapshotHash` | string | No | Feed snapshot to use (defaults to current) |

+
+## Scheduled Replay
+
+Scans can be automatically replayed when feed snapshots change.
+
+### Configuration
+
+```yaml
+# config/scanner.yaml
+score_replay:
+  enabled: true
+  schedule: "0 4 * * *"  # Daily at 4 AM UTC
+  max_age_days: 30       # Only replay scans from last 30 days
+  notify_on_delta: true  # Send notification if scores change
+  delta_threshold: 0.5   # Only notify if delta > threshold
+```
+
+### Trigger Types
+
+| Type | Description |
+|------|-------------|
+| `manual` | User-initiated via API |
+| `feed_update` | Triggered by new feed snapshot |
+| `policy_change` | Triggered by policy version change |
+| `scheduled` | Triggered by scheduled job |
+
+## Determinism Guarantees
+
+Score replay guarantees deterministic results when:
+
+1. **Same manifest hash** - All inputs are identical
+2. **Same scanner version** - Scoring algorithm unchanged
+3. **Same policy version** - Policy rules unchanged
+
+### Manifest Contents
+
+The manifest captures:
+- SBOM content hash
+- Rules snapshot hash
+- Advisory feed snapshot hash
+- Policy configuration hash
+- Scanner version
+
+### Verification
+
+```bash
+# Verify replay determinism
+curl -H "Authorization: Bearer $TOKEN" \
+  "https://scanner.example.com/api/v1/scans/{scanId}/manifest" \
+  | jq '.manifestHash'
+
+# Compare with replay
+curl -H "Authorization: Bearer $TOKEN" \
+  "https://scanner.example.com/api/v1/score/replays/{replayId}" \
+  | jq '.replayedManifestHash'
+```
+
+## Error Responses
+
+| Status | Code | Description |
+|--------|------|-------------|
+| 400 | `INVALID_SCAN_ID` | Scan ID not found |
+| 400 | `INVALID_FEED_SNAPSHOT` | Feed snapshot not found |
+| 400 | `MANIFEST_NOT_FOUND` | Scan manifest missing |
+| 401 | `UNAUTHORIZED` | Invalid token |
+| 403 | `FORBIDDEN` | Insufficient permissions |
+| 409 | `REPLAY_IN_PROGRESS` | Replay already running for scan |
+| 429 | `RATE_LIMITED` | Too many requests |
+
+## Rate Limits
+
+- POST replay: 10 requests/minute
+- GET replays: 100 requests/minute
+- GET manifest: 100 requests/minute

+# Stella Ops Triage API Contract v1
+
+Base path: `/api/triage/v1`
+
+This contract is served by `scanner.webservice` (or a dedicated triage facade that reads scanner-owned tables).
+All risk/lattice outputs originate from `scanner.webservice`.
+
+Key requirements:
+- Deterministic outputs (policyId + policyVersion + inputsHash).
+- Proof-linking (chips reference evidenceIds).
+- `concelier` and `excititor` preserve prune source: API surfaces source chains via `sourceRefs`.
+
+## 0. Conventions
+
+### 0.1 Identifiers
+- `caseId` == `findingId` (UUID). A case is a finding scoped to an asset/environment.
+- Hashes are hex strings.
+
+### 0.2 Caching
+- GET endpoints SHOULD return `ETag`.
+- Clients SHOULD send `If-None-Match`.
+
+### 0.3 Errors
+Standard error envelope:
+
+```json
+{
+  "error": {
+    "code": "string",
+    "message": "string",
+    "details": { "any": "json" },
+    "traceId": "string"
+  }
+}
+```
+
+Common codes:
+
+* `not_found`
+* `validation_error`
+* `conflict`
+* `unauthorized`
+* `forbidden`
+* `rate_limited`
+
+## 1. Findings Table
+
+### 1.1 List findings
+
+`GET /findings`

+* `pageSize` (int, default 50; max 200)
+* `sort` (optional: `updatedAt`, `score`, `lane`)
+* `order` (optional: `asc|desc`)
+
+Response 200:
+
+```json

+
+## Reason Codes
+
+| Code | Description |
+|------|-------------|
+| `missing_vex` | No VEX statement for vulnerability |
+| `ambiguous_indirect_call` | Indirect call target unresolved |
+| `incomplete_sbom` | SBOM missing component data |
+| `unknown_platform` | Platform not recognized |
+| `missing_advisory` | No advisory data for CVE |
+| `conflicting_evidence` | Multiple conflicting data sources |
+| `stale_data` | Data exceeds freshness threshold |
+
+## Score Calculation
+
+The unknown score is calculated as:
+
+```
+score = 0.60 × blast + 0.30 × scarcity + 0.30 × pressure + containment_deduction
+```
+
+Where:
+- `blast` = normalized blast radius (0-1)
+- `scarcity` = evidence scarcity factor (0-1)  
+- `pressure` = exploit pressure (EPSS + KEV factor)
+- `containment_deduction` = -0.10 for enforced seccomp, -0.10 for read-only FS
+
+### Blast Radius Normalization
+
+```
+dependents_normalized = min(dependents / 50, 1.0)
+net_factor = 0.5 if net_facing else 0.0
+priv_factor = 0.5 if privilege == "root" else 0.0
+blast = min((dependents_normalized + net_factor + priv_factor) / 2, 1.0)
+```
+
+### Exploit Pressure
+
+```
+epss_normalized = epss ?? 0.35  // Default if unknown
+kev_factor = 0.30 if kev else 0.0
+pressure = min(epss_normalized + kev_factor, 1.0)
+```

+# Accuracy Metrics Framework
+
+## Overview
+
+This document defines the accuracy metrics framework used to measure and track StellaOps scanner performance. All metrics are computed against ground truth datasets and published quarterly.
+
+## Metric Definitions
+
+### Confusion Matrix
+
+For binary classification tasks (e.g., reachable vs unreachable):
+
+|  | Predicted Positive | Predicted Negative |
+|--|-------------------|-------------------|
+| **Actual Positive** | True Positive (TP) | False Negative (FN) |
+| **Actual Negative** | False Positive (FP) | True Negative (TN) |
+
+### Core Metrics
+
+| Metric | Formula | Description | Target |
+|--------|---------|-------------|--------|
+| **Precision** | TP / (TP + FP) | Of items flagged, how many were correct | >= 90% |
+| **Recall** | TP / (TP + FN) | Of actual positives, how many were found | >= 85% |
+| **F1 Score** | 2 * (P * R) / (P + R) | Harmonic mean of precision and recall | >= 87% |
+| **False Positive Rate** | FP / (FP + TN) | Rate of incorrect positive flags | <= 10% |
+| **Accuracy** | (TP + TN) / Total | Overall correctness | >= 90% |
+
+---
+
+## Reachability Analysis Accuracy
+
+### Definitions
+
+- **True Positive (TP)**: Correctly identified as reachable (code path actually exists)
+- **False Positive (FP)**: Incorrectly identified as reachable (no real code path)
+- **True Negative (TN)**: Correctly identified as unreachable (no code path exists)
+- **False Negative (FN)**: Incorrectly identified as unreachable (code path exists but missed)
+
+### Target Metrics
+
+| Metric | Target | Stretch Goal |
+|--------|--------|--------------|
+| Precision | >= 90% | >= 95% |
+| Recall | >= 85% | >= 90% |
+| F1 Score | >= 87% | >= 92% |
+| False Positive Rate | <= 10% | <= 5% |
+
+### Per-Language Targets
+
+| Language | Precision | Recall | F1 | Notes |
+|----------|-----------|--------|-----|-------|

+# Fidelity Metrics Framework
+
+> Sprint: SPRINT_3403_0001_0001_fidelity_metrics
+
+This document describes the three-tier fidelity metrics framework for measuring deterministic reproducibility in StellaOps scanner outputs.
+
+## Overview
+
+Fidelity metrics quantify how consistently the scanner produces outputs across replay runs. The framework provides three tiers of measurement, each capturing different aspects of reproducibility:
+
+| Metric | Abbrev. | Description | Target |
+|--------|---------|-------------|--------|
+| Bitwise Fidelity | BF | Byte-for-byte identical outputs | ≥ 0.98 |
+| Semantic Fidelity | SF | Normalized object equivalence | ≥ 0.99 |
+| Policy Fidelity | PF | Policy decision consistency | ≈ 1.0 |
+
+## Metric Definitions
+
+### Bitwise Fidelity (BF)
+
+Measures the proportion of replay runs that produce byte-for-byte identical outputs.
+
+```
+BF = identical_outputs / total_replays
+```
+
+**What it captures:**
+- SHA-256 hash equivalence of all output artifacts
+- Timestamp consistency
+- JSON formatting consistency
+- Field ordering consistency
+
+**When BF < 1.0:**
+- Timestamps embedded in outputs
+- Non-deterministic field ordering
+- Floating-point rounding differences
+- Random identifiers (UUIDs)
+
+### Semantic Fidelity (SF)
+
+Measures the proportion of replay runs that produce semantically equivalent outputs, ignoring formatting differences.
+
+```
+SF = semantic_matches / total_replays
+```
+
+**What it compares:**
+- Package PURLs and versions
+- CVE identifiers
+- Severity levels (normalized to uppercase)
+- VEX verdicts
+- Reason codes
+
+**When SF < 1.0 but BF = SF:**
+- No actual content differences
+- Only formatting differences
+
+**When SF < 1.0:**
+- Different packages detected
+- Different CVEs matched
+- Different severity assignments
+
+### Policy Fidelity (PF)
+
+Measures the proportion of replay runs that produce matching policy decisions.
+
+```
+PF = policy_matches / total_replays
+```
+
+**What it compares:**
+- Final pass/fail decision
+- Reason codes (sorted for comparison)
+- Policy rule triggering
+
+**When PF < 1.0:**
+- Policy outcome differs between runs
+- Indicates a non-determinism bug that affects user-visible decisions
+
+## Prometheus Metrics
+
+The fidelity framework exports the following metrics:
+
+| Metric Name | Type | Labels | Description |
+|-------------|------|--------|-------------|
+| `fidelity_bitwise_ratio` | Gauge | tenant_id, surface_id | Bitwise fidelity ratio |
+| `fidelity_semantic_ratio` | Gauge | tenant_id, surface_id | Semantic fidelity ratio |
+| `fidelity_policy_ratio` | Gauge | tenant_id, surface_id | Policy fidelity ratio |
+| `fidelity_total_replays` | Gauge | tenant_id, surface_id | Number of replays |
+| `fidelity_slo_breach_total` | Counter | breach_type, tenant_id | SLO breach count |
+
+## SLO Thresholds
+
+Default SLO thresholds (configurable):
+
+| Metric | Warning | Critical |
+|--------|---------|----------|
+| Bitwise Fidelity | < 0.98 | < 0.90 |
+| Semantic Fidelity | < 0.99 | < 0.95 |
+| Policy Fidelity | < 1.0 | < 0.99 |
+
+## Integration with DeterminismReport
+
+Fidelity metrics are integrated into the `DeterminismReport` record:
+
+```csharp
+public sealed record DeterminismReport(
+    // ... existing fields ...
+    FidelityMetrics? Fidelity = null);
+
+public sealed record DeterminismImageReport(
+    // ... existing fields ...
+    FidelityMetrics? Fidelity = null);
+```
+
+## Usage Example
+
+```csharp
+// Create fidelity metrics service
+var service = new FidelityMetricsService(
+    new BitwiseFidelityCalculator(),
+    new SemanticFidelityCalculator(),
+    new PolicyFidelityCalculator());
+
+// Compute fidelity from baseline and replays
+var baseline = LoadScanResult("scan-baseline.json");
+var replays = LoadReplayScanResults();
+var fidelity = service.Compute(baseline, replays);
+
+// Check thresholds
+if (fidelity.BitwiseFidelity < 0.98)
+{
+    logger.LogWarning("BF below threshold: {BF}", fidelity.BitwiseFidelity);
+}
+
+// Include in determinism report
+var report = new DeterminismReport(
+    // ... other fields ...
+    Fidelity: fidelity);
+```
+
+## Mismatch Diagnostics
+
+When fidelity is below threshold, the framework provides diagnostic information:
+
+```csharp
+public sealed record FidelityMismatch
+{
+    public required int RunIndex { get; init; }
+    public required FidelityMismatchType Type { get; init; }
+    public required string Description { get; init; }
+    public IReadOnlyList<string>? AffectedArtifacts { get; init; }
+}
+
+public enum FidelityMismatchType
+{
+    BitwiseOnly,    // Hash differs but content equivalent
+    SemanticOnly,   // Content differs but policy matches
+    PolicyDrift     // Policy decision differs
+}
+```
+
+## Configuration
+
+Configure fidelity options via `FidelityThresholds`:
+
+```json
+{
+  "Fidelity": {
+    "BitwiseThreshold": 0.98,
+    "SemanticThreshold": 0.99,
+    "PolicyThreshold": 1.0,
+    "EnableDiagnostics": true,
+    "MaxMismatchesRecorded": 100
+  }
+}
+```

+## Corpus Maintenance
+
+### Adding New Samples
+
+1. Create sample binary with known sink reachability
+2. Write `sample.manifest.json` with ground-truth annotations
+3. Place in `datasets/reachability/ground-truth/{category}/`
+4. Update corpus version in `datasets/reachability/corpus.json`
+5. Run baseline update: `stellaops bench baseline update`
+
+### Updating Baselines
+

+
+### Regression Detection Rules
+
+1. **Warning**: Alert engineering team, add to release notes
+2. **Blocking**: Cannot merge/release until resolved or waived
+3. **Waiver**: Requires documented justification and SME approval

+```
+
+### Scan Performance
+
+```bash
+# Cold start measurement
+time stellaops scan --image alpine:3.19 --format json > /dev/null
+
+# Warm cache measurement (run 3x, take average)
+for i in {1..3}; do

+  grep "Maximum resident set size"
+
+# CPU profiling
+perf stat stellaops scan --image alpine:3.19 --format json > /dev/null
+```
+
+### Reachability Analysis
+
+```bash
+# Time measurement
+time stellaops reach --project ./src --language csharp --out reach.json
+
+# Memory profiling
+/usr/bin/time -v stellaops reach --project ./src --language csharp --out reach.json 2>&1
+
+# With detailed timing
+stellaops reach --project ./src --language csharp --out reach.json --timing
+```

+
+## Optimization Guidelines
+
+### For Scan Performance
+
+1. **Pre-pull images** for consistent timing
+2. **Use layered caching** for repeat scans
+3. **Enable parallel analysis** for multi-ecosystem images
+4. **Consider selective scanning** for known-safe layers
+
+### For Reachability
+
+1. **Incremental analysis** for unchanged files
+2. **Cache resolved dependencies**
+3. **Use language-specific optimizations** (e.g., Roslyn for C#)
+4. **Limit call graph depth** for very large codebases
+
+### For Memory
+
+1. **Stream large SBOMs** instead of loading fully
+2. **Use batched database operations**
+3. **Release intermediate data structures early**
+4. **Configure GC appropriately for workload**

 ## TL;DR
 - StellaOps runs as a multi-service platform with deterministic SBOM generation, attestation (DSSE + Rekor), and tenant-aware controls, whereas Grype is a single Go CLI that leans on Syft to build SBOMs before vulnerability matching.[1](#sources)[g1](#grype-sources)
 - Grype covers a broad OS and language matrix via Syft catalogers and Anchore’s aggregated vulnerability database, but it lacks attestation, runtime usage context, and secret management features found in StellaOps’ Surface/Policy ecosystem.[1](#sources)[g2](#grype-sources)[g3](#grype-sources)

 ## TL;DR
 - StellaOps delivers a self-hosted, multi-service scanning plane with deterministic SBOMs, attestation (DSSE + Rekor), and tenant-aware Surface controls, while the Snyk CLI is a Node.js tool that authenticates against Snyk’s SaaS to analyse dependency graphs, containers, IaC, and code.[1](#sources)[s1](#snyk-sources)
 - Snyk’s plugin ecosystem covers many package managers (npm, yarn, pnpm, Maven, Gradle, NuGet, Go modules, Composer, etc.) and routes scans through Snyk’s cloud for policy, reporting, and fix advice; however it lacks offline operation, deterministic evidence, and attestation workflows that StellaOps provides out of the box.[1](#sources)[s1](#snyk-sources)[s2](#snyk-sources)

 ## TL;DR
 - StellaOps Scanner stays focused on deterministic, tenant-scoped SBOM production with signed evidence, policy hand-offs, and Surface primitives that keep offline deployments first-class.[1](#sources)
 - Trivy delivers broad, single-binary coverage (images, filesystems, repos, VMs, Kubernetes, SBOM input) with multiple scanners (vuln, misconfig, secret, license) and a rich plugin ecosystem, but it leaves provenance, signing, and multi-tenant controls to downstream tooling.[8](#sources)

+# Smart-Diff Weighted Impact Index (WII)
+
+**Source Advisory:** `docs/product-advisories/unprocessed/16-Dec-2025 - Smart‑Diff Meets Call‑Stack Reachability.md`  
+**Status:** Processed 2025-12-17
+
+## Overview
+
+The Weighted Impact Index (WII) is a composite score (0-100) that combines Smart-Diff semantic analysis with call-stack reachability to measure the runtime risk of code changes. It proves not just "what changed" but "how risky the change is in reachable code."
+
+## Core Concepts
+
+### Inputs
+
+1. **Smart-Diff Output** - Semantic differences between artifact states
+2. **Call Graph** - Symbol nodes with call edges
+3. **Entrypoints** - HTTP routes, jobs, message handlers
+4. **Runtime Heat** - pprof, APM, or eBPF execution frequency data
+5. **Advisory Data** - CVSS v4, EPSS v4 scores
+
+### WII Scoring Model
+
+The WII uses 8 weighted features per diff unit:
+
+| Feature | Weight | Description |
+|---------|--------|-------------|
+| `Δreach_len` | 0.25 | Change in shortest reachable path length |
+| `Δlib_depth` | 0.10 | Change in library call depth |
+| `exposure` | 0.15 | Public/external-facing API |
+| `privilege` | 0.15 | Path crosses privileged sinks |
+| `hot_path` | 0.15 | Frequently executed (runtime evidence) |
+| `cvss_v4` | 0.10 | Normalized CVSS v4 severity |
+| `epss_v4` | 0.10 | Exploit probability |
+| `guard_coverage` | -0.10 | Sanitizers/validations reduce score |
+
+### Determinism Bonus
+
+When `reachability == true` AND (`cvss_v4 > 0.7` OR `epss_v4 > 0.5`), add +5 bonus for "evidence-linked determinism."
+
+### Formula
+
+```
+WII = clamp(0, 1, Σ(w_i × feature_i_normalized)) × 100
+```
+
+## Data Structures
+
+### DiffUnit
+
+```json
+{
+  "unitId": "pkg:npm/lodash@4.17.21#function:merge",
+  "change": "modified",
+  "before": {"hash": "sha256:abc...", "attrs": {}},
+  "after": {"hash": "sha256:def...", "attrs": {}},
+  "features": {
+    "reachable": true,
+    "reachLen": 3,
+    "libDepth": 2,
+    "exposure": true,
+    "privilege": false,
+    "hotPath": true,
+    "cvssV4": 0.75,
+    "epssV4": 0.45,
+    "guardCoverage": false
+  },
+  "wii": 68
+}
+```
+
+### Artifact-Level WII
+
+Two metrics for artifact-level impact:
+- `max(WII_unit)` - Spike impact (single highest risk change)
+- `p95(WII_unit)` - Broad impact (distribution of risk)
+
+## DSSE Attestation
+
+The WII is emitted as a DSSE-signed attestation:
+
+```json
+{
+  "_type": "https://in-toto.io/Statement/v1",
+  "subject": [{"name": "ghcr.io/acme/app:1.9.3", "digest": {"sha256": "..."}}],
+  "predicateType": "https://stella-ops.org/attestations/smart-diff-wii@v1",
+  "predicate": {
+    "artifactBefore": {"digest": {"sha256": "..."}},
+    "artifactAfter": {"digest": {"sha256": "..."}},
+    "evidence": {
+      "sbomBefore": {"digest": {"sha256": "..."}},
+      "sbomAfter": {"digest": {"sha256": "..."}},
+      "callGraph": {"digest": {"sha256": "..."}},
+      "runtimeHeat": {"optional": true, "digest": {"sha256": "..."}}
+    },
+    "units": [...],
+    "aggregateWII": {
+      "max": 85,
+      "p95": 62,
+      "mean": 45
+    }
+  }
+}
+```
+
+## Pipeline Integration
+
+1. **Collect** - Build call graph, import SBOMs, CVE/EPSS data
+2. **Diff** - Run Smart-Diff to generate `DiffUnit[]`
+3. **Enrich** - Query reachability engine per unit
+4. **Score** - Compute per-unit and aggregate WII
+5. **Attest** - Emit DSSE statement with evidence URIs
+6. **Store** - Proof-Market Ledger (Rekor) + PostgreSQL
+
+## Use Cases
+
+### CI/CD Gates
+
+```yaml
+# .github/workflows/security.yml
+- name: Smart-Diff WII Check
+  run: |
+    stellaops smart-diff \

+      --target ${{ env.TARGET_IMAGE }} \
+      --wii-threshold 70 \
+      --fail-on-threshold
+```
+
+### Risk Prioritization
+
+Sort changes by WII for review prioritization:
+
+```bash
+stellaops smart-diff show \
+  --sort wii \
+  --format table
+```
+

+# Tiered Precision Curves for Scanner Accuracy
+
+**Advisory:** 16-Dec-2025 - Measuring Progress with Tiered Precision Curves  
+**Status:** Processing  
+**Related Sprints:** SPRINT_3500_0003_0001 (Ground-Truth Corpus)
+
+## Executive Summary
+
+This advisory introduces a tiered approach to measuring scanner accuracy that prevents metric gaming. By tracking precision/recall separately for three evidence tiers (Imported, Executed, Tainted→Sink), we ensure improvements in one tier don't hide regressions in another.
+
+## Key Concepts
+
+### Evidence Tiers
+
+| Tier | Description | Risk Level | Typical Volume |
+|------|-------------|------------|----------------|
+| **Imported** | Vuln exists in dependency | Lowest | High |
+| **Executed** | Code/deps actually run | Medium | Medium |
+| **Tainted→Sink** | User data reaches sink | Highest | Low |
+
+### Tier Precedence
+
+Highest tier wins when a finding has multiple evidence types:
+1. `tainted_sink` (highest)
+2. `executed`
+3. `imported`
+
+## Implementation Components
+
+### 1. Evidence Schema (`eval` schema)
+
+```sql
+-- Ground truth samples
+eval.sample(sample_id, name, repo_path, commit_sha, language, scenario, entrypoints)
+
+-- Expected findings
+eval.expected_finding(expected_id, sample_id, vuln_key, tier, rule_key, sink_class)
+
+-- Evaluation runs
+eval.run(eval_run_id, scanner_version, rules_hash, concelier_snapshot_hash)
+
+-- Observed results
+eval.observed_finding(observed_id, eval_run_id, sample_id, vuln_key, tier, score, rule_key, evidence)
+
+-- Computed metrics
+eval.metrics(eval_run_id, tier, op_point, precision, recall, f1, pr_auc, latency_p50_ms)
+```
+
+### 2. Scanner Worker Changes
+
+Workers emit evidence primitives:
+- `DependencyEvidence { purl, version, lockfile_path }`
+- `ReachabilityEvidence { entrypoint, call_path[], confidence }`
+- `TaintEvidence { source, sink, sanitizers[], dataflow_path[], confidence }`
+
+### 3. Scanner WebService Changes
+
+WebService performs tiering:
+- Merge evidence for same `vuln_key`
+- Run reachability/taint algorithms
+- Assign `evidence_tier` deterministically
+- Persist normalized findings
+
+### 4. Evaluator CLI
+
+New tool `StellaOps.Scanner.Evaluation.Cli`:
+- `import-corpus` - Load samples and expected findings
+- `run` - Trigger scans using replay manifest
+- `compute` - Calculate per-tier PR curves
+- `report` - Generate markdown artifacts
+
+### 5. CI Gates
+
+Fail builds when:
+- PR-AUC(imported) drops > 2%
+- PR-AUC(executed/tainted_sink) drops > 1%
+- FP rate in `tainted_sink` > 5% at Recall ≥ 0.7
+
+## Operating Points
+
+| Tier | Target Recall | Purpose |
+|------|--------------|---------|
+| `imported` | ≥ 0.60 | Broad coverage |
+| `executed` | ≥ 0.70 | Material risk |
+| `tainted_sink` | ≥ 0.80 | Actionable findings |
+
+## Integration with Existing Systems
+
+### Concelier
+- Stores advisory data, does not tier
+- Tag advisories with sink classes when available
+
+### Excititor (VEX)
+- Include `tier` in VEX statements
+- Allow policy per-tier thresholds
+- Preserve pruning provenance
+
+### Notify
+- Gate alerts on tiered thresholds
+- Page only on `tainted_sink` at operating point
+
+### UI
+- Show tier badge on findings
+- Default sort: tainted_sink > executed > imported
+- Display evidence summary (entrypoint, path length, sink class)
+
+## Success Criteria
+
+1. Can demonstrate release where overall precision stayed flat but tainted→sink PR-AUC improved
+2. On-call noise reduced via tier-gated paging
+3. TTFS p95 for tainted→sink within budget

+# Only tainted_sink findings
+stellaops scan image:tag --output-format sarif --tier tainted_sink
+
+# Executed and tainted_sink
+stellaops scan image:tag --output-format sarif --tier executed,tainted_sink
+```
+
+### By Priority
+
+```bash
+# Only high priority changes
+stellaops smart-diff --output-format sarif --min-priority 0.7
+```
+
+## Troubleshooting
+
+### SARIF Validation Errors
+
+If your CI platform rejects the SARIF output:
+
+1. Validate against schema:
+   ```bash
+   stellaops validate-sarif results.sarif
+   ```
+
+2. Check for required fields:
+   - `$schema` must be present
+   - `version` must be `"2.1.0"`
+   - Each result must have `ruleId` and `message`
+
+### Empty Results
+
+If SARIF contains no results:
+- Check scan completed successfully
+- Verify image has vulnerability data
+- Ensure feed snapshots are current

+# Smart-Diff Scoring Configuration Guide
+
+**Sprint:** SPRINT_3500_0004_0001  
+**Task:** SDIFF-BIN-031 - Documentation for scoring configuration
+
+## Overview
+
+Smart-Diff uses configurable scoring weights to prioritize material risk changes. This guide explains how to customize scoring for your organization's risk appetite.
+
+## Configuration Location
+
+Smart-Diff scoring can be configured via:
+1. **PolicyScoringConfig** - Integrated with policy engine
+2. **SmartDiffScoringConfig** - Standalone configuration
+3. **Environment variables** - Runtime overrides
+4. **API** - Dynamic configuration
+
+## Default Configuration
+
+```json
+{
+  "name": "default",
+  "version": "1.0",
+  "reachabilityFlipUpWeight": 1.0,
+  "reachabilityFlipDownWeight": 0.8,
+  "vexFlipToAffectedWeight": 0.9,
+  "vexFlipToNotAffectedWeight": 0.7,
+  "vexFlipToFixedWeight": 0.6,
+  "vexFlipToUnderInvestigationWeight": 0.3,
+  "rangeEntryWeight": 0.8,
+  "rangeExitWeight": 0.6,
+  "kevAddedWeight": 1.0,
+  "epssThreshold": 0.1,
+  "epssThresholdCrossWeight": 0.5,
+  "hardeningRegressionWeight": 0.7,
+  "hardeningImprovementWeight": 0.3,
+  "hardeningRegressionThreshold": 0.1
+}
+```
+
+## Weight Categories
+
+### Reachability Weights (R1)
+
+Controls scoring for reachability status changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `reachabilityFlipUpWeight` | 1.0 | Unreachable → Reachable (risk increase) |
+| `reachabilityFlipDownWeight` | 0.8 | Reachable → Unreachable (risk decrease) |
+| `useLatticeConfidence` | true | Factor in reachability confidence |
+
+**Example scenarios:**
+- Vulnerability becomes reachable after code refactoring → weight = 1.0
+- Dependency removed, vulnerability no longer reachable → weight = 0.8
+
+### VEX Status Weights (R2)
+
+Controls scoring for VEX statement changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `vexFlipToAffectedWeight` | 0.9 | Status changed to "affected" |
+| `vexFlipToNotAffectedWeight` | 0.7 | Status changed to "not_affected" |
+| `vexFlipToFixedWeight` | 0.6 | Status changed to "fixed" |
+| `vexFlipToUnderInvestigationWeight` | 0.3 | Status changed to "under_investigation" |
+
+**Rationale:**
+- "affected" is highest weight as it confirms exploitability
+- "fixed" is lower as it indicates remediation
+- "under_investigation" is lowest as status is uncertain
+
+### Version Range Weights (R3)
+
+Controls scoring for affected version range changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `rangeEntryWeight` | 0.8 | Version entered affected range |
+| `rangeExitWeight` | 0.6 | Version exited affected range |
+
+### Intelligence Signal Weights (R4)
+
+Controls scoring for external intelligence changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `kevAddedWeight` | 1.0 | Vulnerability added to CISA KEV |
+| `epssThreshold` | 0.1 | EPSS score threshold for significance |
+| `epssThresholdCrossWeight` | 0.5 | Weight when EPSS crosses threshold |
+
+### Binary Hardening Weights (R5)
+
+Controls scoring for binary hardening flag changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `hardeningRegressionWeight` | 0.7 | Security flag disabled (e.g., NX removed) |
+| `hardeningImprovementWeight` | 0.3 | Security flag enabled (e.g., PIE added) |
+| `hardeningRegressionThreshold` | 0.1 | Minimum score drop to flag regression |
+
+## Presets
+
+### Default Preset
+
+Balanced configuration suitable for most organizations.
+
+```csharp
+SmartDiffScoringConfig.Default
+```
+
+### Strict Preset
+
+Higher weights for regressions, recommended for security-critical applications.
+
+```csharp
+SmartDiffScoringConfig.Strict
+```
+
+Configuration:
+```json
+{
+  "name": "strict",
+  "reachabilityFlipUpWeight": 1.2,
+  "vexFlipToAffectedWeight": 1.1,
+  "kevAddedWeight": 1.5,
+  "hardeningRegressionWeight": 1.0,
+  "hardeningRegressionThreshold": 0.05
+}
+```
+
+### Lenient Preset
+
+Lower weights for alerts, suitable for development/staging environments.
+
+```json
+{
+  "name": "lenient",
+  "reachabilityFlipUpWeight": 0.7,
+  "vexFlipToAffectedWeight": 0.6,
+  "kevAddedWeight": 0.8,
+  "hardeningRegressionWeight": 0.4,
+  "epssThreshold": 0.2
+}
+```
+
+## Policy Integration
+
+Smart-Diff scoring integrates with `PolicyScoringConfig`:
+
+```csharp
+var config = new PolicyScoringConfig(
+    Version: "1.0",
+    SeverityWeights: severityWeights,
+    QuietPenalty: 0.1,
+    WarnPenalty: 0.5,
+    IgnorePenalty: 0.0,
+    TrustOverrides: trustOverrides,
+    ReachabilityBuckets: reachabilityBuckets,
+    UnknownConfidence: unknownConfig,
+    SmartDiff: new SmartDiffPolicyScoringConfig(
+        ReachabilityFlipUpWeight: 1.0,
+        VexFlipToAffectedWeight: 0.9,
+        KevAddedWeight: 1.2
+    )
+);
+```
+
+## Environment Variable Overrides
+
+```bash
+# Override reachability weights
+export STELLAOPS_SMARTDIFF_REACHABILITY_FLIP_UP_WEIGHT=1.2
+export STELLAOPS_SMARTDIFF_REACHABILITY_FLIP_DOWN_WEIGHT=0.7
+
+# Override KEV weight
+export STELLAOPS_SMARTDIFF_KEV_ADDED_WEIGHT=1.5
+
+# Override hardening threshold
+export STELLAOPS_SMARTDIFF_HARDENING_REGRESSION_THRESHOLD=0.05
+```
+
+## API Configuration
+
+### Get Current Configuration
+
+```bash
+GET /api/v1/config/smart-diff/scoring
+
+Response:
+{
+  "name": "default",
+  "version": "1.0",
+  "weights": { ... }
+}
+```
+
+### Update Configuration
+
+```bash
+PUT /api/v1/config/smart-diff/scoring
+Content-Type: application/json
+
+{
+  "reachabilityFlipUpWeight": 1.2,
+  "kevAddedWeight": 1.5
+}
+```
+
+## Score Calculation Formula
+
+The final priority score is calculated as:
+
+```
+priority_score = base_severity × Σ(change_weight × rule_match)
+```
+
+Where:
+- `base_severity` is the CVSS/severity normalized to 0-1
+- `change_weight` is the configured weight for the change type
+- `rule_match` is 1 if the rule triggered, 0 otherwise
+
+### Example Calculation
+
+Given:
+- CVE-2024-1234 with CVSS 7.5 (base_severity = 0.75)
+- Became reachable (reachabilityFlipUpWeight = 1.0)
+- Added to KEV (kevAddedWeight = 1.0)
+
+```
+priority_score = 0.75 × (1.0 + 1.0) = 1.5 → capped at 1.0
+```
+
+## Tuning Recommendations
+
+### For CI/CD Pipelines
+
+```json
+{
+  "kevAddedWeight": 1.5,
+  "hardeningRegressionWeight": 1.2,
+  "epssThreshold": 0.05
+}
+```
+
+Focus on blocking builds for known exploited vulnerabilities and hardening regressions.
+
+### For Alert Fatigue Reduction
+
+```json
+{
+  "reachabilityFlipDownWeight": 0.3,
+  "vexFlipToNotAffectedWeight": 0.2,
+  "rangeExitWeight": 0.2
+}
+```
+
+Lower weights for positive changes to reduce noise.
+
+### For Compliance Focus
+
+```json
+{
+  "kevAddedWeight": 2.0,
+  "vexFlipToAffectedWeight": 1.2,
+  "hardeningRegressionThreshold": 0.02
+}
+```
+
+Higher weights for regulatory-relevant changes.
+
+## Monitoring and Metrics
+
+Track scoring effectiveness with:
+
+```sql
+-- Average priority score by rule type
+SELECT 
+  change_type,
+  AVG(priority_score) as avg_score,
+  COUNT(*) as count
