Refactor and enhance tests for call graph extractors and connection management

- Updated JavaScriptCallGraphExtractorTests to improve naming conventions and test cases for Azure Functions, CLI commands, and socket handling.
- Modified NodeCallGraphExtractorTests to correctly assert exceptions for null inputs.
- Enhanced WitnessModalComponent tests in Angular to use Jasmine spies and improved assertions for path visualization and signature verification.
- Added ConnectionState property for tracking connection establishment time in Router.Common.
- Implemented validation for HelloPayload in ConnectionManager to ensure required fields are present.
- Introduced RabbitMqContainerFixture method for restarting RabbitMQ container during tests.
- Added integration tests for RabbitMq to verify connection recovery after broker restarts.
- Created new BinaryCallGraphExtractorTests, GoCallGraphExtractorTests, and PythonCallGraphExtractorTests for comprehensive coverage of binary, Go, and Python call graph extraction functionalities.
- Developed ConnectionManagerTests to validate connection handling, including rejection of invalid hello messages and proper cleanup on client disconnects.

+# Determinism Benchmark Suite
+
+> **Purpose:** Verify that StellaOps produces bit-identical results across replays.
+> **Status:** Active
+> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
+
+## Overview
+
+Determinism is a core differentiator for StellaOps:
+- Same inputs → same outputs (bit-identical)
+- Replay manifests enable audit verification
+- No hidden state or environment leakage
+
+## What Gets Tested
+
+### Canonical JSON
+- Object key ordering (alphabetical)
+- Number formatting consistency
+- UTF-8 encoding without BOM
+- No whitespace variation
+
+### Scan Manifests
+- Same artifact + same feeds → same manifest hash
+- Seed values propagate correctly
+- Timestamp handling (fixed UTC)
+
+### Proof Bundles
+- Root hash computation
+- DSSE envelope determinism
+- ProofLedger node ordering
+
+### Score Computation
+- Same manifest → same score
+- Lattice merge is associative/commutative
+- Policy rule ordering doesn't affect outcome
+
+## Test Cases
+
+### TC-001: Canonical JSON Determinism
+
+```bash
+# Run same object through CanonJson 100 times
+# All hashes must match
+```
+
+### TC-002: Manifest Hash Stability
+
+```bash
+# Create manifest with identical inputs
+# Verify ComputeHash() returns same value
+```
+
+### TC-003: Cross-Platform Determinism
+
+```bash
+# Run on Linux, Windows, macOS
+# Compare output hashes
+```
+
+### TC-004: Feed Snapshot Determinism
+
+```bash
+# Same feed snapshot hash → same scan results
+```
+
+## Fixtures
+
+```

+```
+
+## Metrics
+
+| Metric | Target | Description |
+|--------|--------|-------------|
+| Hash stability | 100% | All runs produce identical hash |
+| Replay success | 100% | All replays match original |
+| Cross-platform parity | 100% | Same hash across OS/arch |

+# 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
+
+## Running Benchmarks
+
+### Prerequisites
+
+- .NET 10 SDK
+- PostgreSQL 16+ (for database benchmarks)
+- BenchmarkDotNet 0.14+
+
+### Quick Start
+
+```bash
+# Run all benchmarks
+cd bench/proof-chain
+dotnet run -c Release
+
+# Run specific benchmark class
+dotnet run -c Release -- --filter *IdGeneration*
+
+# Export results
+dotnet run -c Release -- --exporters json markdown
+```
+
+## Benchmark Categories
+
+### 1. ID Generation Benchmarks
+
+```csharp
+[MemoryDiagnoser]
+public class IdGenerationBenchmarks
+{
+    [Benchmark(Baseline = true)]
+    public string GenerateEvidenceId_Small() => GenerateEvidenceId(SmallPayload);

+
+    [Benchmark]
+    public ProofBundle AssembleSpine() => Assembler.AssembleSpine(
+        Evidence.Take(EvidenceCount),
+        Reasoning,
+        VexVerdict);
+
+    [Benchmark]
+    public byte[] MerkleTreeConstruction() => BuildMerkleTree(Leaves);
+}
+```
+
+**Target Metrics:**
+- Spine assembly (5 evidence items): < 5ms
+- Merkle tree (100 leaves): < 1ms
+- Deterministic output: 100% reproducibility
+
+### 3. Verification Pipeline Benchmarks
+
+```csharp

+    [Benchmark]
+    public VerificationResult VerifyRekorInclusion() => Pipeline.VerifyRekor(Bundle);
+
+    [Benchmark]
+    public VerificationResult FullVerification() => Pipeline.VerifyAsync(Bundle).Result;
+}
+```
+
+**Target Metrics:**
+- DSSE signature verification: < 5ms per envelope
+- ID recomputation: < 2ms per bundle
+- Rekor verification (cached): < 10ms
+- Full pipeline: < 50ms typical
+
+### 4. Key Rotation Benchmarks
+
+```csharp
+[MemoryDiagnoser]
+public class KeyRotationBenchmarks
+{
+    [Benchmark]
+    public TrustAnchor FindAnchorByPurl() => Manager.FindAnchorForPurlAsync(Purl).Result;
+
+    [Benchmark]

+
+## 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 |

+# Smart-Diff Benchmark Suite
+
+> **Purpose:** Prove deterministic smart-diff reduces noise compared to naive diff.
+> **Status:** Active
+> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
+
+## Overview
+
+The Smart-Diff feature enables incremental scanning by:
+1. Computing structural diffs of SBOMs/dependencies
+2. Identifying only changed components
+3. Avoiding redundant scanning of unchanged packages
+4. Producing deterministic, reproducible diff results
+
+## Test Cases
+
+### TC-001: Layer-Aware Diff
+
+Tests that Smart-Diff correctly handles container layer changes:
+- Adding a layer
+- Removing a layer
+- Modifying a layer (same hash, different content)
+
+### TC-002: Package Version Diff
+
+Tests accurate detection of package version changes:
+- Minor version bump
+- Major version bump
+- Pre-release version handling
+- Epoch handling (RPM)
+
+### TC-003: Noise Reduction
+
+Compares smart-diff output vs naive diff for real-world images:
+- Measure CVE count reduction
+- Measure scanning time reduction
+- Verify determinism (same inputs → same outputs)
+
+### TC-004: Deterministic Ordering
+
+Verifies that diff results are:
+- Sorted by component PURL
+- Ordered consistently across runs
+- Independent of filesystem ordering

+## Running the Suite
+
+```bash
+# Run all smart-diff tests
+dotnet test tests/StellaOps.Scanner.SmartDiff.Tests
+
+# Run benchmark comparison
+./run-benchmark.sh --baseline naive --compare smart
+
+# Generate metrics report
+./tools/analyze.py results/ --output metrics.csv
+```
+
+## Metrics Collected
+
+| Metric | Description |
+|--------|-------------|
+| `diff_time_ms` | Time to compute diff |
+| `changed_packages` | Number of packages marked as changed |
+| `false_positive_rate` | Packages incorrectly flagged as changed |
+| `determinism_score` | 1.0 if all runs produce identical output |
+| `noise_reduction_pct` | % reduction vs naive diff |
+
+## Expected Results
+
+For typical Alpine base image upgrades (3.18 → 3.19):
+- **Naive diff:** ~150 packages flagged as changed
+- **Smart diff:** ~12 packages actually changed
+- **Noise reduction:** ~92%

+# Unknowns Tracking Benchmark Suite
+
+> **Purpose:** Verify epistemic uncertainty tracking and unknown state management.
+> **Status:** Active
+> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
+
+## Overview
+
+StellaOps tracks "unknowns" - gaps in knowledge that affect confidence:
+- Missing SBOM components
+- Unmatched CVEs
+- Stale feed data
+- Zero-day windows
+- Analysis limitations
+
+## What Gets Tested
+
+### Unknown State Lifecycle
+1. Detection of unknown conditions
+2. Propagation to affected findings
+3. Score penalty application
+4. Resolution tracking
+
+### Unknown Categories
+- `SBOM_GAP`: Component not in SBOM
+- `CVE_UNMATCHED`: CVE without component mapping
+- `FEED_STALE`: Feed data older than threshold
+- `ZERO_DAY_WINDOW`: Time between disclosure and feed update
+- `ANALYSIS_LIMIT`: Depth/timeout constraints
+
+### Score Impact
+- Each unknown type has a penalty weight
+- Penalties reduce overall confidence
+- Resolved unknowns restore confidence
+
+## Test Cases

+# VEX Lattice Benchmark Suite
+
+> **Purpose:** Verify VEX lattice merge semantics and jurisdiction rules.
+> **Status:** Active
+> **Sprint:** SPRINT_3850_0001_0001 (Competitive Gap Closure)
+
+## Overview
+
+StellaOps implements VEX (Vulnerability Exploitability eXchange) with:
+- Lattice-based merge semantics (stable outcomes)
+- Jurisdiction-specific trust rules (US/EU/RU/CN)
+- Source precedence and confidence weighting
+- Deterministic conflict resolution
+
+## What Gets Tested
+
+### Lattice Properties
+- Idempotency: merge(a, a) = a
+- Commutativity: merge(a, b) = merge(b, a)
+- Associativity: merge(merge(a, b), c) = merge(a, merge(b, c))
+- Monotonicity: once "not_affected", never regresses
+
+### Status Precedence
+Order from most to least specific:
+1. `not_affected` (strongest)
+2. `affected` (with fix)
+3. `under_investigation`
+4. `affected` (no fix)
+
+### Jurisdiction Rules
+- US: FDA/NIST sources preferred
+- EU: ENISA/BSI sources preferred
+- RU: FSTEC sources preferred
+- CN: CNVD sources preferred
+
+## Test Cases
+
+### TC-001: Idempotency

+# Regulator-Grade Threat & Evidence Model
+
+## Supply-Chain Risk Decisioning Platform (Reference: “Stella Ops”)
+
+**Document version:** 1.0
+**Date:** 2025-12-19
+**Intended audience:** Regulators, third-party auditors, internal security/compliance, and engineering leadership
+**Scope:** Threat model + evidence model for a platform that ingests SBOM/VEX and other supply-chain signals, produces risk decisions, and preserves an audit-grade evidence trail.
+
+---
+
+## 1. Purpose and Objectives
+
+This document defines:
+
+1. A **threat model** for a supply-chain risk decisioning platform (“the Platform”) and its critical workflows.
+2. An **evidence model** describing what records must exist, how they must be protected, and how they must be presented to support regulator-grade auditability and non-repudiation.
+
+The model is designed to support the supply-chain transparency goals behind SBOM/VEX and secure software development expectations (e.g., SSDF), and to be compatible with supply-chain risk management (C‑SCRM) and control-based assessments (e.g., NIST control catalogs). 
+
+---
+
+## 2. Scope, System Boundary, and Assumptions
+
+### 2.1 In-scope system functions
+
+The Platform performs the following high-level functions:
+
+* **Ingest** software transparency artifacts (e.g., SBOMs, VEX documents), scan results, provenance attestations, and policy inputs.
+* **Normalize** to a canonical internal representation (component identity graph + vulnerability/impact graph).
+* **Evaluate** with a deterministic policy engine to produce decisions (e.g., allow/deny, risk tier, required remediation).
+* **Record** an audit-grade evidence package supporting each decision.
+* **Export** reports and attestations suitable for procurement, regulator review, and downstream consumption.
+
+### 2.2 Deployment models supported by this model
+
+This model is written to cover:
+
+* **On‑prem / air‑gapped** deployments (offline evidence and curated vulnerability feeds).
+* **Dedicated single-tenant hosted** deployments.
+* **Multi-tenant SaaS** deployments (requires stronger tenant isolation controls and evidence).
+
+### 2.3 Core assumptions
+
+* SBOM is treated as a **formal inventory and relationship record** for components used to build software. 
+* VEX is treated as a **machine-readable assertion** of vulnerability status for a product, including “not affected / affected / fixed / under investigation.” 
+* The Platform must be able to demonstrate **traceability** from decision → inputs → transformations → outputs, and preserve “known unknowns” (explicitly tracked uncertainty). 
+* If the Platform is used in US federal acquisition contexts, it must anticipate evolving SBOM minimum element guidance; CISA’s 2025 SBOM minimum elements draft guidance explicitly aims to update the 2021 NTIA baseline to reflect tooling and maturity improvements. ([Federal Register][1])
+
+---
+
+## 3. Normative and Informative References
+
+This model is aligned to the concepts and terminology used by the following:
+
+* **SBOM minimum elements baseline (2021 NTIA)** and the “data fields / automation support / practices and processes” structure. 
+* **CISA 2025 SBOM minimum elements draft guidance** (published for comment; successor guidance to NTIA baseline per the Federal Register notice). ([Federal Register][1])
+* **VEX overview and statuses** (NTIA one-page summary). 
+* **NIST SSDF** (SP 800‑218; includes recent Rev.1 IPD for SSDF v1.2). ([NIST Computer Security Resource Center][2])
+* **NIST C‑SCRM guidance** (SP 800‑161 Rev.1). ([NIST Computer Security Resource Center][3])
+* **NIST security and privacy controls catalog** (SP 800‑53 Rev.5, including its supply chain control family). ([NIST Computer Security Resource Center][4])
+* **SLSA supply-chain threat model and mitigations** (pipeline threat clustering A–I; verification threats). ([SLSA][5])
+* **Attestation and transparency building blocks**:
+
+  * in‑toto (supply-chain metadata standard). ([in-toto][6])
+  * DSSE (typed signing envelope to reduce confusion attacks). ([GitHub][7])
+  * Sigstore Rekor (signature transparency log). ([Sigstore][8])
+* **SBOM and VEX formats**:
+
+  * CycloneDX (ECMA‑424; SBOM/BOM standard). ([GitHub][9])
+  * SPDX (ISO/IEC 5962:2021; SBOM standard). ([ISO][10])
+  * CSAF v2.0 VEX profile (structured security advisories with VEX profile requirements). ([OASIS Documents][11])
+  * OpenVEX (minimal VEX implementation). ([GitHub][12])
+* **Vulnerability intelligence format**:
+
+  * OSV schema maps vulnerabilities to package versions/commit ranges. ([OSV.dev][13])
+
+---
+
+## 4. System Overview
+
+### 4.1 Logical architecture
+
+**Core components:**
+
+1. **Ingestion Gateway**
+
+   * Accepts SBOM, VEX, provenance attestations, scan outputs, and configuration inputs.
+   * Performs syntactic validation, content hashing, and initial authenticity checks.
+
+2. **Normalization & Identity Resolution**
+
+   * Converts formats (SPDX, CycloneDX, proprietary) into a canonical internal model.
+   * Resolves component IDs (purl/CPE/name+version), dependency graph, and artifact digests.
+
+3. **Evidence Store**
+
+   * Content-addressable object store for raw artifacts plus derived artifacts.
+   * Append-only metadata index (event log) referencing objects by hash.
+
+4. **Policy & Decision Engine**
+
+   * Deterministic evaluation engine for risk policy.
+   * Produces a decision plus a structured explanation and “unknowns.”
+
+5. **Attestation & Export Service**
+
+   * Packages decisions and evidence references as signed statements (DSSE/in‑toto compatible). ([GitHub][7])
+   * Optional transparency publication (e.g., Rekor or private transparency log). ([Sigstore][8])
+
+### 4.2 Trust boundaries
+
+**Primary trust boundaries:**
+
+* **TB‑1:** External submitter → Ingestion Gateway
+* **TB‑2:** Customer environment → Platform environment (for hosted)
+* **TB‑3:** Policy authoring plane → decision execution plane
+* **TB‑4:** Evidence Store (write path) → Evidence Store (read/audit path)
+* **TB‑5:** Platform signing keys / KMS / HSM boundary → application services
+* **TB‑6:** External intelligence feeds (vulnerability databases, advisories) → internal curated dataset
+
+---
+
+## 5. Threat Model
+
+### 5.1 Methodology
+
+This model combines:
+
+* **STRIDE** for platform/system threats (spoofing, tampering, repudiation, information disclosure, denial of service, elevation of privilege).
+* **SLSA threat clustering (A–I)** for supply-chain pipeline threats relevant to artifacts being evaluated and to the Platform’s own supply chain. ([SLSA][5])
+
+Threats are evaluated as: **Impact × Likelihood**, with controls grouped into **Prevent / Detect / Respond**.
+
+### 5.2 Assets (what must be protected)
+
+**A‑1: Decision integrity assets**
+
+* Final decision outputs (allow/deny, risk scores, exceptions).
+* Decision explanations and traces.
+* Policy rules and parameters (including weights/thresholds).
+
+**A‑2: Evidence integrity assets**
+
+* Original input artifacts (SBOM, VEX, provenance, scan outputs).
+* Derived artifacts (normalized graphs, reachability proofs, diff outputs).
+* Evidence index and chain-of-custody metadata.
+
+**A‑3: Confidentiality assets**
+
+* Customer source code and binaries (if ingested).
+* Private SBOMs/VEX that reveal internal dependencies.
+* Customer environment identifiers and incident details.
+
+**A‑4: Trust anchor assets**
+
+* Signing keys (decision attestations, evidence hashes, transparency submissions).
+* Root of trust configuration (certificate chains, allowed issuers).
+* Time source and timestamping configuration.
+
+**A‑5: Availability assets**
+
+* Evidence store accessibility.
+* Policy engine uptime.
+* Interface endpoints and batch processing capacity.
+
+### 5.3 Threat actors
+
+* **External attacker** seeking to:
+
+  * Push a malicious component into the supply chain,
+  * Falsify transparency artifacts,
+  * Or compromise the Platform to manipulate decisions/evidence.
+
+* **Malicious insider** (customer or Platform operator) seeking to:
+
+  * Hide vulnerable components,
+  * Suppress detections,
+  * Or retroactively alter records.
+
+* **Compromised CI/CD or registry** affecting provenance and artifact integrity (SLSA build/distribution threats). ([SLSA][5])
+
+* **Curious but non-malicious parties** who should not gain access to sensitive SBOM details (confidentiality and least privilege).
+
+### 5.4 Key threat scenarios and required mitigations
+
+Below are regulator-relevant threats that materially affect auditability and trust.
+
+---
+
+### T‑1: Spoofing of submitter identity (STRIDE: S)
+
+**Scenario:**
+An attacker submits forged SBOM/VEX/provenance claiming to be a trusted supplier.
+
+**Impact:**
+Decisions are based on untrusted artifacts; audit trail is misleading.
+
+**Controls (shall):**
+
+* Enforce strong authentication for ingestion (mTLS/OIDC + scoped tokens).
+* Require artifact signatures for “trusted supplier” classification; verify signature chain and allowed issuers.
+* Bind submitter identity to evidence record at ingestion time (AU-style accountability expectations). ([NIST Computer Security Resource Center][4])
+
+**Evidence required:**
+
+* Auth event logs (who/when/what).
+* Signature verification results (certificate chain, key ID).
+* Hash of submitted artifact (content-addressable ID).
+
+---
+
+### T‑2: Tampering with stored evidence (STRIDE: T)
+
+**Scenario:**
+An attacker modifies an SBOM, a reachability artifact, or an evaluation trace after the decision, to change what regulators/auditors see.
+
+**Impact:**
+Non-repudiation and auditability collapse; regulator confidence lost.
+
+**Controls (shall):**
+
+* Evidence objects stored as **content-addressed blobs** (hash = identifier).
+* **Append-only metadata log** referencing evidence hashes (no in-place edits).
+* Cryptographically sign the “evidence package manifest” for each decision.
+* Optional transparency log anchoring (public Rekor or private equivalent). ([Sigstore][8])
+
+**Evidence required:**
+
+* Object store digest list and integrity proofs.
+* Signed manifest (DSSE envelope recommended to bind payload type). ([GitHub][7])
+* Inclusion proof or anchor reference if using a transparency log. ([Sigstore][8])
+
+---
+
+### T‑3: Repudiation of decisions or approvals (STRIDE: R)
+
+**Scenario:**
+A policy author or approver claims they did not approve a policy change or a high-risk exception.
+
+**Impact:**
+Weak governance; cannot establish accountability.
+
+**Controls (shall):**
+
+* Two-person approval workflow for policy changes and exceptions.
+* Immutable audit logs capturing: identity, time, action, object, outcome (aligned with audit record content expectations). ([NIST Computer Security Resource Center][4])
+* Sign policy versions and exception artifacts.
+
+**Evidence required:**
+
+* Signed policy version artifacts.
+* Approval records linked to identity provider logs.
+* Change diff + rationale.
+
+---
+
+### T‑4: Information disclosure via SBOM/VEX outputs (STRIDE: I)
+
+**Scenario:**
+An auditor-facing export inadvertently reveals proprietary component lists, internal repo URLs, or sensitive dependency relationships.
+
+**Impact:**
+Confidentiality breach; contractual/regulatory exposure; risk of targeted exploitation.
+
+**Controls (shall):**
+
+* Role-based access control for evidence and exports.
+* Redaction profiles (“regulator view,” “customer view,” “internal view”) with deterministic transformation rules.
+* Separate encryption domains (tenant-specific keys).
+* Secure export channels; optional offline export bundles for air-gapped review.
+
+**Evidence required:**
+
+* Access-control policy snapshots and enforcement logs.
+* Export redaction policy version and redaction transformation log.
+
+---
+
+### T‑5: Denial of service against evaluation pipeline (STRIDE: D)
+
+**Scenario:**
+A malicious party floods ingestion endpoints or submits pathological SBOM graphs causing excessive compute and preventing timely decisions.
+
+**Impact:**
+Availability and timeliness failures; missed gates/releases.
+
+**Controls (shall):**
+
+* Input size limits, graph complexity limits, and bounded parsing.
+* Quotas and rate limiting (per tenant or per submitter).
+* Separate async pipeline for heavy analysis; protect decision critical path.
+
+**Evidence required:**
+
+* Rate limit logs and rejection metrics.
+* Capacity monitoring evidence (for availability obligations).
+
+---
+
+### T‑6: Elevation of privilege to policy/admin plane (STRIDE: E)
+
+**Scenario:**
+An attacker compromises a service account and gains ability to modify policy, disable controls, or access evidence across tenants.
+
+**Impact:**
+Complete compromise of decision integrity and confidentiality.
+
+**Controls (shall):**
+
+* Strict separation of duties: policy authoring vs execution vs auditing.
+* Least privilege IAM for services (scoped tokens; short-lived credentials).
+* Strong hardening of signing key boundary (KMS/HSM boundary; key usage constrained by attestation policy).
+
+**Evidence required:**
+
+* IAM policy snapshots and access review logs.
+* Key management logs (rotation, access, signing operations).
+
+---
+
+### T‑7: Supply-chain compromise of artifacts being evaluated (SLSA A–I)
+
+**Scenario:**
+The software under evaluation is compromised via source manipulation, build pipeline compromise, dependency compromise, or distribution channel compromise.
+
+**Impact:**
+Customer receives malicious/vulnerable software; Platform may miss it without sufficient provenance and identity proofs.
+
+**Controls (should / shall depending on assurance target):**
+
+* Require/provide provenance attestations and verify them against expectations (SLSA-style verification). ([SLSA][5])
+* Verify artifact identity by digest and signed provenance.
+* Enforce policy constraints for “minimum acceptable provenance” for high-criticality deployments.
+
+**Evidence required:**
+
+* Verified provenance statement(s) (in‑toto compatible) describing how artifacts were produced. ([in-toto][6])
+* Build and publication step attestations, with cryptographic binding to artifact digests.
+* Evidence of expectation configuration and verification outcomes (SLSA “verification threats” include tampering with expectations). ([SLSA][5])
+
+---
+
+### T‑8: Vulnerability intelligence poisoning / drift
+
+**Scenario:**
+The Platform’s vulnerability feed is manipulated or changes over time such that a past decision cannot be reproduced.
+
+**Impact:**
+Regulator cannot validate basis of decision at time-of-decision; inconsistent results over time.
+
+**Controls (shall):**
+
+* Snapshot all external intelligence inputs used in an evaluation (source + version + timestamp + digest).
+* In offline mode, use curated signed feed bundles and record their hashes.
+* Maintain deterministic evaluation by tying each decision to the exact dataset snapshot.
+
+**Evidence required:**
+
+* Feed snapshot manifest (hashes, source identifiers, effective date range).

+
+## 6. Evidence Model
+
+### 6.1 Evidence principles (regulator-grade properties)
+
+All evidence objects in the Platform **shall** satisfy:
+
+1. **Integrity:** Evidence cannot be modified without detection (hashing + immutability).
+2. **Authenticity:** Evidence is attributable to its source (signatures, verified identity). 
+3. **Traceability:** Decisions link to specific input artifacts and transformation steps.
+4. **Reproducibility:** A decision can be replayed deterministically given the same inputs and dataset snapshots.
+5. **Non‑repudiation:** Critical actions (policy updates, exceptions, decision signing) are attributable and auditable.
+6. **Confidentiality:** Sensitive evidence is access-controlled and export-redactable.
+7. **Completeness with “Known Unknowns”:** The Platform explicitly records unknown or unresolved data elements rather than silently dropping them. 
+
+### 6.2 Evidence object taxonomy
+
+The Platform should model evidence as a graph of typed objects.
+
+**E‑1: Input artifact evidence**
+
+* SBOM documents (SPDX/CycloneDX), including dependency relationships and identifiers. 
+* VEX documents (CSAF VEX, OpenVEX, CycloneDX VEX) with vulnerability status assertions. 
+* Provenance/attestations (SLSA-style provenance, in‑toto statements). ([SLSA][14])
+* Scan outputs (SCA, container/image scans, static/dynamic analysis outputs).
+
+**E‑2: Normalization and resolution evidence**
+
+* Parsing/validation logs (schema validation results; warnings).
+* Canonical “component graph” and “vulnerability mapping” artifacts.
+* Identity resolution records: how name/version/IDs were mapped.
+
+**E‑3: Analysis evidence**
+
+* Vulnerability match outputs (CVE/OSV IDs, version ranges, scoring).
+* Reachability artifacts (if supported): call graph results, dependency path proofs, or “not reachable” justification artifacts.
+* Diff artifacts: changes between SBOM versions (component added/removed/upgraded; license changes; vulnerability deltas).
+
+**E‑4: Policy and governance evidence**
+
+* Policy definitions and versions (rules, thresholds).
+* Exception records with approver identity and rationale.
+* Approval workflow records and change control logs.
+
+**E‑5: Decision evidence**
+
+* Decision outcome (e.g., pass/fail/risk tier).
+* Deterministic decision trace (which rules fired, which inputs were used).
+* Unknowns/assumptions list.
+* Signed decision statement + manifest of linked evidence objects.
+
+**E‑6: Operational security evidence**
+
+* Authentication/authorization logs.
+* Key management and signing logs.
+* Evidence store integrity monitoring logs.
+* Incident response records (if applicable).
+
+### 6.3 Common metadata schema (minimum required fields)
+
+Every evidence object **shall** include at least:
+
+* **EvidenceID:** content-addressable ID (e.g., SHA‑256 digest of canonical bytes).
+* **EvidenceType:** enumerated type (SBOM, VEX, Provenance, ScanResult, Policy, Decision, etc.).
+* **Producer:** tool/system identity that generated the evidence (name, version).
+* **Timestamp:** time created + time ingested (with time source information).
+* **Subject:** the software artifact(s) the evidence applies to (artifact digest(s), package IDs).
+* **Chain links:** parent EvidenceIDs (inputs/precedents).
+* **Tenant / confidentiality labels:** access classification and redaction profile applicability.
+
+This aligns with the SBOM minimum elements emphasis on baseline data, automation support, and practices/processes including known unknowns and access control. 
+
+### 6.4 Evidence integrity and signing
+
+**6.4.1 Hashing and immutability**
+
+* Raw evidence artifacts shall be stored as immutable blobs.
+* Derived evidence shall be stored as separate immutable blobs.
+* The evidence index shall be append-only and reference blobs by hash.
+
+**6.4.2 Signed envelopes and type binding**
+
+* For high-assurance use, the Platform shall sign:
+
+  * Decision statements,
+  * Per-decision evidence manifests,
+  * Policy versions and exception approvals.
+* Use a signing format that binds the **payload type** to the signature to reduce confusion attacks; DSSE is explicitly designed to authenticate both message and type. ([GitHub][7])
+
+**6.4.3 Attestation model**
+
+* Use in‑toto-compatible statements to standardize subjects (artifact digests) and predicates (decision, SBOM, provenance). ([in-toto][6])
+* CycloneDX explicitly recognizes an official predicate type for BOM attestations, which can be leveraged for standardized evidence typing. ([CycloneDX][15])
+
+**6.4.4 Transparency anchoring (optional but strong for regulators)**
+
+* Publish signed decision manifests to a transparency log to provide additional tamper-evidence and public verifiability (or use a private transparency log for sensitive contexts). Rekor is Sigstore’s signature transparency log service. ([Sigstore][8])
+
+### 6.5 Evidence for VEX and “not affected” assertions
+
+Because VEX is specifically intended to prevent wasted effort on non-exploitable upstream vulnerabilities and is machine-readable for automation, the Platform must treat VEX as first-class evidence. 
+
+Minimum required behaviors:
+
+* Maintain the original VEX document and signature (if present).
+* Track the VEX **status** (not affected / affected / fixed / under investigation) for each vulnerability–product association. 
+* If the Platform generates VEX-like conclusions (e.g., “not affected” based on reachability), it shall:
+
+  * Record the analytical basis as evidence (reachability proof, configuration assumptions),
+  * Mark the assertion as Platform-authored (not vendor-authored),
+  * Provide an explicit confidence level and unknowns.
+
+For CSAF-based VEX documents, the Platform should validate conformance to the CSAF VEX profile requirements. ([OASIS Documents][11])
+
+### 6.6 Reproducibility and determinism controls
+
+Each decision must be reproducible. Therefore each decision record **shall** include:
+
+* **Algorithm version** (policy engine + scoring logic version).
+* **Policy version** and policy hash.
+* **All inputs by digest** (SBOM/VEX/provenance/scan outputs).
+* **External dataset snapshot identifiers** (vulnerability DB snapshot digest(s), advisory feeds, scoring inputs).
+* **Execution environment ID** (runtime build of the Platform component that evaluated).
+* **Determinism proof fields** (e.g., “random seed = fixed/none”, stable sort order used, canonicalization rules used).
+
+This supports regulator expectations for traceability and for consistent evaluation in supply-chain risk management programs. ([NIST Computer Security Resource Center][3])
+
+### 6.7 Retention, legal hold, and audit packaging
+
+**Retention (shall):**
+
+* Evidence packages supporting released decisions must be retained for a defined minimum period (set by sector/regulator/contract), with:
+
+  * Immutable storage and integrity monitoring,
+  * Controlled deletion only through approved retention workflows,
+  * Legal hold support.
+
+**Audit package export (shall):**
+For any decision, the Platform must be able to export an “Audit Package” containing:
+
+1. **Decision statement** (signed)
+2. **Evidence manifest** (signed) listing all evidence objects by hash
+3. **Inputs** (SBOM/VEX/provenance/etc.) or references to controlled-access retrieval
+4. **Transformation chain** (normalization and mapping records)
+5. **Policy version and evaluation trace**
+6. **External dataset snapshot manifests**
+7. **Access-control and integrity verification records** (to prove custody)
+
+---
+
+## 7. Threat-to-Evidence Traceability (Minimal Regulator View)
+
+This section provides a compact mapping from key threat classes to the evidence that must exist to satisfy audit and non-repudiation expectations.
+
+| Threat Class                     | Primary Risk                    | “Must-have” Evidence Outputs                                                                      |
+| -------------------------------- | ------------------------------- | ------------------------------------------------------------------------------------------------- |
+| Spoofing submitter               | Untrusted artifacts used        | Auth logs + signature verification + artifact digests                                             |
+| Tampering with evidence          | Retroactive manipulation        | Content-addressed evidence + append-only index + signed manifest (+ optional transparency anchor) |
+| Repudiation                      | Denial of approval/changes      | Signed policy + approval workflow logs + immutable audit trail                                    |
+| Information disclosure           | Sensitive SBOM leakage          | Access-control evidence + redaction policy version + export logs                                  |
+| DoS                              | Missed gates / delayed response | Rate limiting logs + capacity metrics + bounded parsing evidence                                  |
+| Privilege escalation             | Policy/evidence compromise      | IAM snapshots + key access logs + segregation-of-duty records                                     |
+| Supply-chain pipeline compromise | Malicious artifact              | Provenance attestations + verification results + artifact digest binding                          |
+| Vulnerability feed drift         | Non-reproducible decisions      | Feed snapshot manifests + digests + authenticity verification                                     |
+
+(Where the threat concerns the wider software supply chain, SLSA’s threat taxonomy provides an established clustering for where pipeline threats occur and the role of verification. ([SLSA][5]))
+
+---
+
+## 8. Governance, Control Testing, and Continuous Compliance
+
+To be regulator-grade, the Platform’s security and evidence integrity controls must be governed and tested.
+
+### 8.1 Governance expectations
+
+* Maintain a control mapping to a recognized catalog (e.g., NIST SP 800‑53) for access control, auditing, integrity, and supply-chain risk management. ([NIST Computer Security Resource Center][4])
+* Maintain a supply-chain risk posture aligned with C‑SCRM guidance (e.g., NIST SP 800‑161 Rev.1). ([NIST Computer Security Resource Center][3])
+* Align secure development practices to SSDF expectations and terminology, noting SSDF has an active Rev.1 IPD (v1.2) publication process at NIST. ([NIST Computer Security Resource Center][2])
+
+### 8.2 Control testing (shall)
+
+At minimum, perform and retain evidence of:
+
+* Periodic integrity tests of evidence store immutability and hash verification.
+* Key management audits (signing operations, rotation, restricted usage).
+* Access review audits (especially multi-tenant isolation).
+* Reproducibility tests: re-run evaluation from historical evidence package and confirm identical results.
+
+---
+
+## Appendix A: Example Signed Decision Statement Structure (Conceptual)
+
+This is a conceptual structure (not a normative schema) showing the minimum linkage needed:
+
+* **Subject:** artifact digest(s) + identifiers
+* **Predicate type:** `.../decision` (Platform-defined)
+* **Predicate:** decision outcome + rationale + policy hash + dataset snapshot hashes
+* **Envelope:** DSSE signature with payload type binding ([GitHub][7])
+* **Optional transparency anchor:** Rekor entry UUID / inclusion proof ([Sigstore][8])
+
+---
+
+## Appendix B: Practical Notes for SBOM/VEX Interoperability
+
+* Support both SPDX and CycloneDX ingestion and preservation; both are referenced in SBOM minimum elements discussion and are widely used. 
+* Treat CSAF VEX and OpenVEX as acceptable VEX carriers; validate schema and preserve original artifacts. ([OASIS Documents][11])
+* Capture “known unknowns” explicitly rather than forcing false precision; this is part of SBOM minimum elements’ practices/processes framing and is directly relevant to regulator-grade audit transparency. 
+
+---
+
+## What you can do next with this model
+
+If you want, I can produce any of the following artifacts derived directly from this model (without changing its underlying assertions):
+
+1. A **control-to-evidence crosswalk** (NIST 800‑53 / SSDF / C‑SCRM oriented).
+2. A **test plan** (control testing, evidence integrity validation, reproducibility drills).
+3. A **formal evidence schema** (JSON schema for evidence objects + DSSE envelopes + manifest format).
+4. A **regulator-ready “Audit Package” template** you can hand to third parties (including redaction tiers).

+# 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
+
+BUNDLE_DATE=$(date -u +%Y-%m-%d)
+BUNDLE_DIR="risk-bundle-${BUNDLE_DATE}"

+```
+
+---
+
+## 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_scores inserted (231,417 rows, 23.4s)
+  ✓ epss_changes computed (12,345 changes, 8.1s)
+  ✓ 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
+}
+```

 - Expanded tests for DSSE, TUF, Merkle helpers.
 - Added trust store + root rotation policy (dual approval) and import validator that coordinates DSSE/TUF/Merkle/rotation checks.
 
+## Updates (2025-12-15)
+- Added monotonicity enforcement primitives under `src/AirGap/StellaOps.AirGap.Importer/Versioning/` (`BundleVersion`, `IVersionMonotonicityChecker`, `IBundleVersionStore`).
+- Added file-based quarantine service under `src/AirGap/StellaOps.AirGap.Importer/Quarantine/` (`IQuarantineService`, `FileSystemQuarantineService`, `QuarantineOptions`).
+- Updated `ImportValidator` to include monotonicity checks, force-activate support (requires reason), and quarantine on validation failures.
+- Added Postgres-backed bundle version tracking in `src/AirGap/StellaOps.AirGap.Storage.Postgres/Repositories/PostgresBundleVersionStore.cs` and registration via `src/AirGap/StellaOps.AirGap.Storage.Postgres/ServiceCollectionExtensions.cs`.
+- Updated tests in `tests/AirGap/StellaOps.AirGap.Importer.Tests` to cover versioning/quarantine and the new import validator behavior.

 ## Next implementation hooks
 - Replace placeholder plan with actual DSSE + TUF verifiers; keep step ordering stable.
 - Feed trust roots from sealed-mode config and Evidence Locker bundles (once available) before allowing imports.
 - Record audit trail for each plan step (success/failure) and a Merkle root of staged content.
 
 ## Determinism/air-gap posture
-- No network dependencies; only BCL used.
+- No network dependencies; BCL + `Microsoft.Extensions.*` only.
 - Tests use cached local NuGet feed (`local-nugets/`).

+# 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
+
+## File Format

+    }
+  ]
+}
+```
+
+## 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
+

+# 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",

+      "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

+# │   ├── vex-verdict.dsse
+# │   └── proof-spine.dsse
+# └── 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..."],
+  "results": [
+    {
+      "proofBundleId": "sha256:1a2b3c4d...",
+      "verified": true,

+    "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.

+# Reachability Drift Air-Gap Workflows
+
+**Sprint:** SPRINT_3600_0001_0001  
+**Task:** RDRIFT-MASTER-0006 - Document air-gap workflows for reachability drift
+
+## Overview
+
+Reachability Drift Detection can operate in fully air-gapped environments using offline bundles. This document describes the workflows for running reachability drift analysis without network connectivity, building on the Smart-Diff air-gap patterns.
+
+## Prerequisites
+
+1. **Offline Kit** - Downloaded and verified (`stellaops offline kit download`)
+2. **Feed Snapshots** - Pre-staged vulnerability feeds and surfaces
+3. **Call Graph Cache** - Pre-extracted call graphs for target artifacts
+4. **Vulnerability Surface Bundles** - Pre-computed trigger method mappings
+
+## Key Differences from Online Mode
+
+| Aspect | Online Mode | Air-Gap Mode |
+|--------|-------------|--------------|
+| Surface Queries | Real-time API | Local bundle lookup |
+| Call Graph Extraction | On-demand | Pre-computed + cached |
+| Graph Diff | Direct comparison | Bundle-to-bundle |
+| Attestation | Online transparency log | Offline DSSE bundle |
+| Metrics | Telemetry enabled | Local-only metrics |
+
+---
+
+## Workflow 1: Offline Reachability Drift Analysis
+
+### Step 1: Prepare Offline Bundle with Call Graphs
+
+On a connected machine:
+
+```bash
+# Download offline kit with reachability bundles
+stellaops offline kit download \
+  --output /path/to/offline-bundle \
+  --include-feeds nvd,osv,epss \
+  --include-surfaces \
+  --feed-date 2025-01-15

+# Pre-extract call graphs for known artifacts
+stellaops callgraph extract \

+stellaops offline kit package \
+  --input /path/to/offline-bundle \
+  --output stellaops-reach-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-reach-offline-2025-01-15.tar.gz \
+  --public-key /path/to/signing-key.pub
+
+# Extract and configure
+stellaops offline kit import \
+  --input stellaops-reach-offline-2025-01-15.tar.gz \
+  --data-dir /opt/stellaops/data
+```
+
+### Step 4: Run Reachability Drift Analysis
+
+```bash
+# Set offline mode
+export STELLAOPS_OFFLINE=true
+export STELLAOPS_DATA_DIR=/opt/stellaops/data
+export STELLAOPS_SURFACES_DIR=/opt/stellaops/data/surfaces
+export STELLAOPS_CALLGRAPH_CACHE=/opt/stellaops/data/callgraphs
+
+# Run reachability drift
+stellaops reach-drift \
+  --base-scan scan-v1.json \
+  --current-scan scan-v2.json \
+  --base-callgraph callgraph-v1.json \
+  --current-callgraph callgraph-v2.json \
+  --output drift-report.json \
+  --format json
+```
+
+---
+
+## Workflow 2: Pre-Computed Drift Export
+
+For environments that cannot run the full analysis, pre-compute drift results on a connected machine and export them for review.
+
+### Step 1: Pre-Compute Drift Results
+
+```bash
+# On connected machine: compute drift
+stellaops reach-drift \
+  --base-scan scan-v1.json \
+  --current-scan scan-v2.json \
+  --output drift-results.json \
+  --include-witnesses \
+  --include-paths
+
+# Generate offline viewer bundle
+stellaops offline viewer export \
+  --drift-report drift-results.json \
+  --output drift-viewer-bundle.html \
+  --self-contained
+```
+
+### Step 2: Transfer and Review
+
+The self-contained HTML viewer can be opened in any browser on the air-gapped machine without additional dependencies.
+
+---
+
+## Workflow 3: Incremental Call Graph Updates
+
+For environments that need to update call graphs without full re-extraction.
+
+### Step 1: Export Graph Delta
+
+On connected machine after code changes:
+
+```bash
+# Extract delta since last snapshot
+stellaops callgraph delta \
+  --base-snapshot callgraph-v1.json \
+  --current-source /path/to/code \
+  --output graph-delta.json
+```
+
+### Step 2: Apply Delta in Air-Gap
+
+```bash
+# Merge delta into existing graph
+stellaops callgraph merge \
+  --base /opt/stellaops/data/callgraphs/app-v1.json \
+  --delta graph-delta.json \
+  --output /opt/stellaops/data/callgraphs/app-v2.json
+```

+            └── surfaces.ndjson
+```
+
+---
+
+## Offline Surface Query
+
+When running in air-gap mode, the surface query service automatically uses local bundles:
+
+```csharp
+// Configuration for air-gap mode
+services.AddSingleton<ISurfaceQueryService>(sp =>
+{
+    var options = sp.GetRequiredService<IOptions<AirGapOptions>>().Value;
+    
+    if (options.Enabled)
+    {
+        return new OfflineSurfaceQueryService(
+            options.SurfacesBundlePath,
+            sp.GetRequiredService<ILogger<OfflineSurfaceQueryService>>());
+    }
+    
+    return sp.GetRequiredService<OnlineSurfaceQueryService>();
+});
+```
+
+---
+
+## Attestation in Air-Gap Mode
+
+Reachability drift results can be attested even in offline mode using pre-provisioned signing keys:
+
+```bash
+# Sign drift results with offline key
+stellaops attest sign \
+  --input drift-results.json \
+  --predicate-type https://stellaops.io/attestation/reachability-drift/v1 \
+  --key /opt/stellaops/keys/signing-key.pem \
+  --output drift-attestation.dsse.json
+
+# Verify attestation (offline)
+stellaops attest verify \
+  --input drift-attestation.dsse.json \
+  --trust-root /opt/stellaops/keys/trust-root.json
+```
+
+---
+
+## Staleness Considerations
+
+### Call Graph Freshness
+
+Call graphs should be re-extracted when:
+- Source code changes significantly
+- Dependencies are updated
+- Framework versions change
+
+Maximum recommended staleness: **7 days** for active development, **30 days** for stable releases.
+
+### Surface Bundle Freshness
+
+Surface bundles should be updated when:
+- New CVEs are published
+- Vulnerability details are refined
+- Trigger methods are updated
+
+Maximum recommended staleness: **24 hours** for high-security environments, **7 days** for standard environments.
+
+### Staleness Indicators
+
+```bash
+# Check bundle freshness
+stellaops offline status \
+  --data-dir /opt/stellaops/data
+
+# Output:
+# Bundle Type      | Last Updated        | Age    | Status
+# -----------------|---------------------|--------|--------
+# NVD Feed         | 2025-01-15T00:00:00 | 3 days | OK
+# OSV Feed         | 2025-01-15T00:00:00 | 3 days | OK
+# Surfaces         | 2025-01-14T12:00:00 | 4 days | WARNING
+# Call Graphs (v1) | 2025-01-10T08:00:00 | 8 days | STALE
+```
+
+---
+
+## Determinism Requirements
+
+All offline workflows must produce deterministic results:
+
+1. **Call Graph Extraction** - Same source produces identical graph hash
+2. **Drift Detection** - Same inputs produce identical drift report
+3. **Path Witnesses** - Same reachability query produces identical paths
+4. **Attestation** - Signature over canonical JSON (sorted keys, no whitespace)
+
+Verification:
+
+```bash
+# Verify determinism
+stellaops reach-drift \
+  --base-scan scan-v1.json \
+  --current-scan scan-v2.json \
+  --output drift-1.json
+
+stellaops reach-drift \
+  --base-scan scan-v1.json \
+  --current-scan scan-v2.json \
+  --output drift-2.json
+
+# Must be identical
+diff drift-1.json drift-2.json
+# (no output = identical)
+```
+
+---
+
+## Troubleshooting
+
+### Missing Surface Data
+
+```
+Error: No surface found for CVE-2024-1234 in package pkg:nuget/Newtonsoft.Json@12.0.1
+```
+
+**Resolution:** Update surface bundle or fall back to package-API-level reachability:
+
+```bash
+stellaops reach-drift \
+  --fallback-mode package-api \
+  ...
+```
+
+### Call Graph Extraction Failure
+
+```
+Error: Failed to extract call graph - missing language support for 'rust'
+```
+
+**Resolution:** Pre-extract call graphs on a machine with required tooling, or skip unsupported languages:
+
+```bash
+stellaops callgraph extract \
+  --skip-unsupported \
+  ...
+```
+
+### Bundle Signature Verification Failure
+
+```
+Error: Bundle signature invalid - public key mismatch
+```
+
+**Resolution:** Ensure correct public key is used, or re-download bundle:
+
+```bash
+# List available trust roots
+stellaops offline trust-roots list
+
+# Import new trust root (requires approval)
+stellaops offline trust-roots import \
+  --key new-signing-key.pub \
+  --fingerprint <expected-fingerprint>
+```

+# 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

+
+### 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 \

+```
+
+## 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:
+# ═══════════════════════════════════════════

+## Bundle Format Specification
+
+### manifest.json
+
+```json
+{
+  "version": "1.0",
+  "type": "triage-bundle",
+  "created_at": "2025-01-15T10:00:00Z",
+  "scan_id": "scan-12345678",
+  "finding_count": 25,
+  "feed_snapshot": "sha256:abc123...",
+  "graph_revision": "sha256:def456...",
+  "signatures": {
+    "manifest": "sha256:ghi789...",
+    "dsse_envelope": "signature.dsse"
+  }
+}
+```
+
+### Decision Format
+
+```json
+{
+  "finding_id": "finding-12345678",
+  "vuln_key": "CVE-2024-1234:pkg:npm/lodash@4.17.20",
+  "status": "not_affected",
+  "justification": "Code path gated by feature flag",
+  "reviewer": "security-team",

+  "replay_token": "rt_abc123...",
+  "evidence_refs": [
+    "evidence/reachability/CVE-2024-1234.json"
+  ]
+}
+```
+
+## 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`:
+```json
+{
+  "FirstSignal": {
+    "Cache": {
+      "Backend": "inmemory",
+      "TtlSeconds": 86400,

+# 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
+
+---

+
+---
+
+## 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

+# 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...",
+  "policyVersion": "1.0.0",
+  "dryRun": false
+}
+```
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `scanId` | string | Yes | Original scan ID to replay |
+| `feedSnapshotHash` | string | No | Feed snapshot to use (defaults to current) |
+| `policyVersion` | string | No | Policy version (defaults to original) |
+| `dryRun` | boolean | No | If true, calculates but doesn't persist |

+```
+
+### Get Proof Bundle
+
+```http
+GET /api/v1/scans/{scanId}/proof-bundle
+```
+
+Downloads the proof bundle (ZIP archive) for a scan.
+
+#### Response
+
+Returns `application/zip` with the proof bundle containing:
+- `manifest.json` - Signed scan manifest
+- `ledger.json` - Proof ledger nodes
+- `sbom.json` - Input SBOM (hash-verified)
+- `findings.json` - Scored findings
+- `signature.dsse` - DSSE envelope
+
+## 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`
+
+Query params:
+
+* `showMuted` (bool, default false)
+* `lane` (optional, enum)
+* `search` (optional string; searches asset, purl, cveId)
+* `page` (int, default 1)
+* `pageSize` (int, default 50; max 200)
+* `sort` (optional: `updatedAt`, `score`, `lane`)
+* `order` (optional: `asc|desc`)
+
+Response 200:
+
+```json
+{
+  "page": 1,
+  "pageSize": 50,
+  "total": 12345,

+# Unknowns API Reference
+
+**Sprint:** SPRINT_3600_0002_0001  
+**Task:** UNK-RANK-011 - Update unknowns API documentation
+
+## Overview
+
+The Unknowns API provides access to items that could not be fully classified due to missing evidence, ambiguous data, or incomplete intelligence. Unknowns are ranked by blast radius, exploit pressure, and containment signals.
+
+## Base URL
+
+```
+/api/v1/unknowns
+```
+
+## Authentication
+
+All endpoints require Bearer token authentication:
+
+```http
+Authorization: Bearer <token>
+```
+
+Required scope: `scanner:unknowns:read`
+
+## Endpoints
+
+### List Unknowns
+
+```http
+GET /api/v1/unknowns
+```
+
+Returns paginated list of unknowns, optionally sorted by score.

+
+## 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)
+```
+
