-
-## Decisions & Risks
-- Decision needed: Can exceptions be self-approved for G1 level? Recommend: yes for G0-G1, no for G2+.
-- Decision needed: Evidence requirement strictness. Recommend: mandatory for G2+, optional for G0-G1.
-- Decision needed: Exception inheritance (repo -> image -> env). Recommend: explicit shadowing with conflict surfacing.
-- Risk: Approval bottleneck slowing releases. Mitigation: parallel approval paths, escalation timeouts.
-- Risk: Expired exceptions causing sudden build failures. Mitigation: 7d/1d expiry warnings, grace period option.

-## Decisions & Risks
-- ✅ Decision made: Java extractor uses pure .NET bytecode parsing (no external ASM dependency needed).
-- ✅ Decision made: Node.js extractor uses Babel via `stella-callgraph-node` external tool with JSON output.
-- ✅ Decision made: Python extractor uses regex-based AST parsing for 3.8+ compatibility.
-- ✅ Decision made: Go extractor uses external `stella-callgraph-go` tool with static fallback analysis.
-- Risk mitigated: Dynamic dispatch in Java/Python - conservative over-approximation implemented, unknowns flagged.
-- Risk mitigated: Node.js dynamic requires - marked as unknown, runtime evidence can supplement.
-- Risk mitigated: Memory for large codebases - streaming/chunked processing with configurable depth limits via `ReachabilityAnalysisOptions.MaxDepth`.

+## Executive Summary
+
+**CRITICAL:** 89% of test files are NOT running in the test-matrix.yml pipeline due to:
+1. Main solution `StellaOps.sln` only contains 16 of 293 test projects
+2. 1,963 test files lack Category traits required for filtering
+3. ~142 test projects are not in ANY solution file

+|--------|-------|------------|
+| Total test projects | 293 | 100% |
+| In main `StellaOps.sln` | 16 | 5.5% |
+| In module solutions (combined) | ~151 | 51.5% |
+| **NOT in any solution** | ~142 | **48.5%** |
+
+### Category Trait Coverage
+
+| Category | Files with Trait | % of 2,208 test files |
+|----------|------------------|----------------------|
+| Unit | 54 | 2.4% |
+| Integration | 66 | 3.0% |
+| Snapshot | 34 | 1.5% |
+| Security | 21 | 1.0% |

+| Architecture | 6 | 0.3% |
+| Performance | 5 | 0.2% |
+| Chaos | 3 | 0.1% |
+| Property | ~20 | 0.9% |
+| **Files WITH any trait** | ~245 | **11.1%** |
+| **Files WITHOUT traits** | ~1,963 | **88.9%** |
+
+### Test Category Mismatch
+
+`TestCategories.cs` defines:
+- Unit, Property, Snapshot, Integration, Contract, Security, Performance, Live
+
+`test-matrix.yml` filters by:

-# Sprint 20251226 · Determinism Advisory and Documentation Consolidation
-
-## Topic & Scope
-- Consolidate 6 overlapping product advisories into a single determinism architecture specification.
-- Create authoritative documentation for all determinism guarantees and digest algorithms.
-- Archive original advisories with cross-reference preservation.
-- **Working directory:** `docs/product-advisories/`, `docs/technical/`
-
-## Dependencies & Concurrency
-- No technical dependencies; documentation-only sprint.
-- Can run in parallel with: SPRINT_20251226_007_BE (determinism gap closure).
-- Should reference implementation status from gap closure sprint.
-
-## Documentation Prerequisites
-- All source advisories (listed in Delivery Tracker)
-- Existing determinism docs:
-  - `docs/modules/policy/design/deterministic-evaluator.md`
-  - `docs/modules/policy/design/policy-determinism-tests.md`

Created `CONSOLIDATED - Deterministic Evidence and Verdict Architecture.md` with 11 sections covering canonical serialization, keyless signing, delta verdicts, reachability proofs, and implementation status matrix (~85% complete). Created `docs/technical/architecture/determinism-specification.md` with complete digest algorithm specs (VerdictId, EvidenceId, GraphRevisionId, ManifestId, PolicyBundleId), canonicalization rules, troubleshooting guide. Updated cross-references in policy architecture and scanner AGENTS. Skipped archival tasks (DOC-DET-08/09) as source files already in appropriate archive locations. | Implementer |
-
-## Decisions & Risks
-- Decision: Keep "Hybrid Binary and Call-Graph Analysis" separate (different focus). Recommend: Yes, it's about analysis methods not determinism.
-- Decision: Archive location. Recommend: `archived/2025-12-26-determinism-advisories/` with README explaining consolidation.
-- Decision: **Archival skipped** — source advisories already reside in `archived/2025-12-25-foundation-advisories/` and `archived/2025-12-26-foundation-advisories/`. Moving them again would break existing cross-references. Added "supersedes" notes in consolidated document instead.
-- Risk: Broken cross-references after archival. Mitigation: grep all docs for advisory filenames before archiving.
-- Risk: Loss of nuance from individual advisories. Mitigation: preserve verbatim sections where noted.

-# Sprint 20251226 · Function-Level Proof Generation (FuncProof)
-
-## Topic & Scope
-- Implement function-level proof objects for binary-level reachability evidence.
-- Generate symbol digests, function-range hashes, and entry→sink trace serialization.
-- Publish FuncProof as DSSE-signed OCI referrer artifacts linked from SBOM.
-- **Working directory:** `src/Scanner/`, `src/BinaryIndex/`, `src/Attestor/`
-
-## Dependencies & Concurrency
-- Depends on: `BinaryIdentity` (complete), `NativeReachabilityGraphBuilder` (complete).

-## Decisions & Risks
-- **DECIDED**: Hash algorithm: Uses `StellaOps.Cryptography.ICryptoHash` with `HashPurpose.Graph` for regional compliance:
-  - `world` profile: BLAKE3-256 (default, fast)
-  - `fips/kcmvp/eidas` profile: SHA-256 (certified)
-  - `gost` profile: GOST3411-2012-256 (Russian)
-  - `sm` profile: SM3 (Chinese)
-  - Fallback: SHA-256 when no ICryptoHash provider is available (backward compatibility).
-  - Configuration: `config/crypto-profiles.sample.json` → `StellaOps.Crypto.Compliance.ProfileId`
-- **DECIDED**: Stripped binary handling: heuristic detection with confidence field (0.5 for heuristics, 0.8 for symbols, 1.0 for DWARF).
-- **DECIDED**: Trace depth limit: 10 hops max (FuncProofConstants.MaxTraceHops). Configurable via policy schema `hopBuckets.maxHops` and `FuncProofGenerationOptions.MaxTraceHops`.
-- **DECIDED**: Function ordering: sorted by offset for deterministic proof ID generation.
-- **DECIDED**: Configurable generation options via `FuncProofGenerationOptions` class:
-  - `MaxTraceHops`: Trace depth limit (default: 10)
-  - `MinConfidenceThreshold`: Filter low-confidence functions (default: 0.0)
-  - `DwarfConfidence`: DWARF detection confidence (default: 1.0)
-  - `SymbolConfidence`: Symbol table confidence (default: 0.8)
-  - `HeuristicConfidence`: Prolog/epilog detection confidence (default: 0.5)
-  - `InferredSizePenalty`: Multiplier for inferred sizes (default: 0.9)
-- **DECIDED**: SBOM evidence linking uses CycloneDX 1.6 `components.evidence.callflow` with `stellaops:funcproof:*` properties.
-- Risk: Function boundary detection may be imprecise for heavily optimized code. Mitigation: mark confidence per function.
-- Risk: Large binaries may produce huge FuncProof files. Mitigation: compress, limit to security-relevant functions.

 ## Decisions & Risks
+- **Decision (OFFLINE-07)**: Use HTTP API to llama.cpp server instead of native bindings. This avoids native dependency management and enables airgap deployment via container/systemd.
 - Decision needed: Primary model choice. Recommend: Llama 3 8B (Apache 2.0, good quality/size balance).
 - Decision needed: Quantization level. Recommend: Q4_K_M for CPU, FP16 for GPU.
 - Decision needed: Bundle distribution. Recommend: separate download, not in main installer.

+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2025-12-26 | Sprint created from product advisory analysis; implements auditable exceptions from diff-aware release gates advisory. | Project Mgmt |
+| 2025-12-26 | Added EXCEPT-16 through EXCEPT-21 from "Diff-Aware Releases and Auditable Exceptions" advisory (auto-revalidation, inheritance, OCI attestation). Advisory marked SUPERSEDED. | Project Mgmt |
+| 2025-12-26 | EXCEPT-01 DONE. Created migration 013_exception_approval.sql with exception_approval_requests, exception_approval_audit, and exception_approval_rules tables. Includes RLS policies, indexes, default approval rules per gate level, and helper functions (expire_pending_approval_requests, get_approval_requirements). | Impl |
+| 2025-12-26 | EXCEPT-02 DONE. Created ExceptionApprovalEntity.cs with entity models (ExceptionApprovalRequestEntity, ExceptionApprovalAuditEntity, ExceptionApprovalRuleEntity) and enums (ApprovalRequestStatus, GateLevel, ExceptionReasonCode). Created IExceptionApprovalRepository.cs interface and ExceptionApprovalRepository.cs implementation with full CRUD, approve/reject/cancel, audit trail, and optimistic concurrency. | Impl |
+| 2025-12-26 | EXCEPT-03 DONE. Created ExceptionApprovalRulesService.cs with IExceptionApprovalRulesService interface. Implements gate-level requirements (G0=auto-approve, G1=1 peer, G2=code owner, G3=DM+PM, G4=CISO+DM+PM), request validation, approval action validation, and required approver determination. Supports tenant-specific rules with fallback to defaults. | Impl |
+| 2025-12-26 | EXCEPT-04 DONE. Added ExceptionsRequest scope ("exceptions:request") to StellaOpsScopes.cs in Authority. ExceptionsApprove already existed. | Impl |
+| 2025-12-26 | EXCEPT-05 to EXCEPT-07 DONE. Created ExceptionApprovalEndpoints.cs with POST /request, POST /{requestId}/approve, POST /{requestId}/reject, POST /{requestId}/cancel, GET /request/{requestId}, GET /requests, GET /pending, GET /{requestId}/audit, GET /rules endpoints.

+| 2025-12-26 | EXCEPT-15 DONE. Sprint marked as done. Core approval workflow complete (EXCEPT-01 through EXCEPT-11). Deferred tasks (EXCEPT-12-14, EXCEPT-16-21) are enhancements requiring Notify Guild, Scheduler Guild, and Attestor Guild integration - can be done in follow-up sprints. | Impl |
+
+## Decisions & Risks
+- Decision: Self-approval allowed for G0-G1, not for G2+. Implemented in ApprovalRequirements.GetDefault().
+- Decision: Evidence required for G2+, optional for G0-G1. Implemented in rules validation.
+- Decision: Exception inheritance (repo -> image -> env) deferred to follow-up sprint (EXCEPT-18).
+- Risk: Approval bottleneck slowing releases. Mitigation: parallel approval paths via RequiredApproverIds array.
+- Risk: Expired exceptions causing sudden build failures. Mitigation: 7-day request expiry window, TTL enforcement.
+
+## Next Checkpoints
+- 2025-12-30 | EXCEPT-03 complete | Approval rules engine implemented | DONE
+- 2026-01-03 | EXCEPT-07 complete | All API endpoints functional | DONE
+- 2026-01-06 | EXCEPT-14 complete | Full workflow integration tested | DEFERRED

+# AI Attestations and Replay Semantics
+
+> **Sprint:** SPRINT_20251226_018_AI_attestations
+> **Task:** AIATTEST-23
+
+This guide documents the AI attestation schemas, authority classification, and deterministic replay semantics.
+
+## Overview
+
+AI-generated artifacts in StellaOps are wrapped in cryptographic attestations that:
+1. Capture the exact inputs (prompts, context, model parameters)
+2. Prove the generation chain (model ID, weights digest, configuration)
+3. Enable deterministic replay for compliance verification
+4. Support divergence detection across environments
+
+## Attestation Types
+
+### AI Artifact Predicate
+
+```json
+{
+  "_type": "https://stellaops.org/attestation/ai-artifact/v1",

+  },
+  "replayManifest": {
+    "manifestId": "replay-20251226-001",
+    "manifestHash": "sha256:manifest..."
+  }
+}
+```
+
+### Artifact Types
+
+| Type | Description | Authority |
+|------|-------------|-----------|
+| `explanation` | Vulnerability explanation for humans | `ai-generated` |
+| `remediation` | Fix plan with upgrade paths | `ai-generated` |
+| `vex_draft` | Draft VEX statement | `ai-draft-requires-review` |
+| `policy_draft` | Draft policy rules | `ai-draft-requires-review` |
+| `triage_suggestion` | Triage action suggestions | `ai-suggestion` |
+
+### Authority Classification
+
+AI outputs are classified by their authority level:
+
+```
+ai-generated           → Informational only, human review optional
+ai-draft-requires-review → Draft requires explicit human approval
+ai-suggestion          → Suggestion, user decides action
+ai-verified            → AI output verified against ground truth
+human-approved         → AI output approved by human reviewer
+```
+
+## Replay Manifest
+
+The replay manifest captures everything needed to reproduce an AI generation:
+
+```json
+{
+  "manifestVersion": "1.0",
+  "artifactId": "ai-artifact-20251226-001",
+  "artifactType": "explanation",
+
+  "model": {
+    "modelId": "llama3-8b-q4km",
+    "weightsDigest": "sha256:a1b2c3d4e5f6...",
+    "promptTemplateVersion": "v2.1.0"
+  },
+
+  "prompts": {
+    "systemPrompt": "You are a security analyst...",
+    "userPrompt": "Explain CVE-2024-1234 affecting lodash@4.17.20...",
+    "systemPromptHash": "sha256:abc123...",
+    "userPromptHash": "sha256:def456..."
+  },
+
+  "context": {
+    "contextPack": [...],
+    "contextHashes": ["sha256:111...", "sha256:222..."]
+  },
+
+  "parameters": {
+    "temperature": 0.0,
+    "seed": 42,
+    "maxTokens": 2048,
+    "topK": 1,
+    "topP": 1.0
+  },
+
+  "output": {
+    "content": "CVE-2024-1234 is a critical vulnerability...",
+    "contentHash": "sha256:789xyz...",
+    "tokenCount": 847
+  },
+
+  "metadata": {
+    "generatedAt": "2025-12-26T10:30:00Z",
+    "replayable": true,
+    "deterministicSettings": true
+  }
+}
+```
+
+## Deterministic Requirements
+
+For an AI artifact to be replayable:
+
+1. **Temperature must be 0**: No randomness in token selection
+2. **Seed must be fixed**: Same seed across replays (default: 42)
+3. **Model weights must match**: Verified by weights digest
+4. **Prompts must match**: Verified by prompt hashes
+5. **Context must match**: All input hashes must verify
+
+### Configuration for Determinism
+
+```yaml
+advisoryAi:
+  attestations:
+    requireDeterminism: true
+    defaultSeed: 42
+
+  inference:
+    local:
+      temperature: 0.0
+      seed: 42
+      topK: 1
+      topP: 1.0
+```
+
+## Replay Workflow
+
+### Replay Execution
+
+```csharp
+// Load replay manifest
+var manifest = await LoadManifestAsync("replay-20251226-001.json");
+
+// Create replayer with same model
+var replayer = replayerFactory.Create(manifest.Model.ModelId);
+
+// Execute replay
+var result = await replayer.ReplayAsync(manifest, cancellationToken);
+
+// Check if output is identical
+if (result.Identical)
+{
+    Console.WriteLine("Replay successful: output matches original");
+}
+else
+{
+    Console.WriteLine($"Divergence detected: similarity = {result.SimilarityScore:P2}");
+}
+```
+
+### Divergence Detection
+
+When replay produces different output:
+
+```json
+{
+  "diverged": true,
+  "similarityScore": 0.97,
+  "originalHash": "sha256:789xyz...",
+  "replayedHash": "sha256:different...",
+  "details": [
+    {
+      "type": "content_divergence",
+      "description": "Content differs at position",
+      "position": 1842,
+      "originalSnippet": "...vulnerability allows...",
+      "replayedSnippet": "...vulnerability permits..."
+    }
+  ]
+}
+```
+
+### Common Divergence Causes
+
+| Cause | Detection | Resolution |
+|-------|-----------|------------|
+| Different model weights | Weights digest mismatch | Use exact model version |
+| Non-zero temperature | Parameter check | Set temperature to 0 |
+| Different seed | Parameter check | Use same seed |
+| Prompt template change | Template version mismatch | Pin template version |
+| Context ordering | Context hash mismatch | Sort context deterministically |
+
+## Attestation Signing
+
+### DSSE Envelope Format
+
+AI attestations use DSSE (Dead Simple Signing Envelope):
+
+```json
+{
+  "payloadType": "application/vnd.stellaops.ai-attestation+json",
+  "payload": "<base64-encoded-attestation>",
+  "signatures": [
+    {
+      "keyId": "stellaops-ai-signer-2025",
+      "sig": "<base64-signature>"
+    }
+  ]
+}
+```
+
+### Signing Configuration
+
+```yaml
+advisoryAi:
+  attestations:
+    sign: true
+    keyId: "stellaops-ai-signer-2025"
+    cryptoScheme: ed25519  # ed25519 | ecdsa-p256 | gost3410 | sm2

+# Explanation API and Replay Semantics
+
+> **Sprint:** SPRINT_20251226_015_AI_zastava_companion
+> **Task:** ZASTAVA-21
+
+This guide documents the Zastava Companion explanation API, attestation format, and replay semantics for evidence-grounded AI explanations.
+
+## Overview
+
+The Explanation API provides evidence-anchored explanations answering:
+- **What** is this vulnerability?
+- **Why** does it matter in this context?
+- **Evidence**: What supports exploitability?
+- **Counterfactual**: What would change the verdict?
+
+All explanations are anchored to verifiable evidence nodes (SBOM, reachability, runtime, VEX, patches).
+
+## Explanation Types
+
+| Type | Purpose | Example Output |
+|------|---------|----------------|
+| `What` | Technical description | "CVE-2024-1234 is a remote code execution vulnerability in lodash's merge function..." |
+| `Why` | Contextual relevance | "This matters because your service uses lodash@4.17.20 in the request handler path..." |
+| `Evidence` | Exploitability proof | "Reachability analysis shows the vulnerable function is called from /api/users endpoint..." |
+| `Counterfactual` | Verdict change conditions | "The verdict would change to 'not affected' if the VEX statement confirmed non-exploitability..." |
+| `Full` | Comprehensive explanation | All of the above in a structured format |

+| `reachability` | Call graph analysis | Function reachability proof |
+| `runtime` | Signals service | Runtime observations (WAF, network) |
+| `vex` | VEX documents | Vendor exploitability statements |
+| `patch` | Package registry | Available fix information |
+
+## Authority Classification
+
+Explanations are classified by their evidence backing:
+
+| Authority | Criteria | Display |
+|-----------|----------|---------|
+| `EvidenceBacked` | ≥80% citation rate, all citations verified | Green badge: "Evidence-backed" |
+| `Suggestion` | <80% citation rate or unverified citations | Yellow badge: "AI suggestion" |
+
+```csharp
+public enum ExplanationAuthority
+{
+    EvidenceBacked,  // All claims anchored to verified evidence
+    Suggestion       // AI suggestion requiring human review
+}
+```
+
+## Attestation Format
+
+Explanations are wrapped in DSSE (Dead Simple Signing Envelope) attestations:
+
+### Predicate Type
+
+```
+https://stellaops.org/attestation/ai-explanation/v1
+```
+
+### Predicate Schema
+
+```json

+  "_type": "https://stellaops.org/attestation/ai-explanation/v1",
+  "explanationId": "expl-20251226-001",
+  "explanationType": "Full",

+    "inputHashes": ["sha256:abc123...", "sha256:def456..."],
+    "evidenceRefs": ["nvd:CVE-2024-1234", "sbom:..."]
+  },
+  "output": {

+    "citationCount": 6
+  },
+  "generatedAt": "2025-12-26T10:30:00Z"
+}
+```
+
+### DSSE Envelope
+
+```json
+{
+  "payloadType": "application/vnd.stellaops.ai-explanation+json",
+  "payload": "<base64-encoded-predicate>",
+  "signatures": [
+    {
+      "keyId": "stellaops-ai-signer-2025",
+      "sig": "<base64-signature>"
+    }
+  ]
+}
+```
+
+### OCI Attachment
+
+Attestations are pushed as OCI referrers:
+
+```
+Artifact: sha256:imagedigest
+  └── Referrer: application/vnd.stellaops.ai-explanation+json
+      └── expl-20251226-001.dsse.json
+```
+
+## Replay Semantics
+
+### Replay Manifest
+
+Every explanation includes a replay manifest enabling deterministic reproduction:
+
+```json
+{
+  "manifestVersion": "1.0",
+  "explanationId": "expl-20251226-001",
+  "model": {
+    "modelId": "claude-sonnet-4-20250514",
+    "weightsDigest": "sha256:modelweights...",
+    "promptTemplateVersion": "v2.1.0"
+  },
+  "inputs": {
+    "findingId": "finding-abc123",
+    "artifactDigest": "sha256:abcdef...",
+    "evidenceHashes": {
+      "advisory": "sha256:111...",
+      "sbom": "sha256:222...",
+      "reachability": "sha256:333..."
+    }
+  },
+  "parameters": {
+    "temperature": 0.0,
+    "seed": 42,
+    "maxTokens": 4096
+  },
+  "output": {
+    "contentHash": "sha256:789xyz...",
+    "generatedAt": "2025-12-26T10:30:00Z"
+  }
+}
+```
+
+### Determinism Requirements
+
+For replay to produce identical output:
+
+| Parameter | Required Value | Purpose |
+|-----------|---------------|---------|
+| `temperature` | `0.0` | No randomness in generation |
+| `seed` | `42` (fixed) | Reproducible sampling |
+| `maxTokens` | Same as original | Consistent truncation |
+| Model version | Exact match | Same weights |
+| Prompt template | Exact match | Same prompt structure |
+
+### Divergence Detection
+
+When replay produces different output:
+
+```json
+{
+  "diverged": true,
+  "similarity": 0.94,
+  "originalHash": "sha256:789xyz...",
+  "replayedHash": "sha256:different...",
+  "divergencePoints": [
+    {
+      "position": 1234,
+      "original": "...uses lodash@4.17.20...",
+      "replayed": "...uses lodash version 4.17.20..."
+    }
+  ],
+  "likelyCause": "model_update"
+}
+```
+
+### Divergence Causes
+
+| Cause | Detection | Resolution |
+|-------|-----------|------------|
+| Model update | Weights digest mismatch | Pin model version |
+| Non-zero temperature | Parameter check | Set temperature=0 |
+| Evidence change | Input hash mismatch | Re-generate explanation |
+| Prompt template change | Template version mismatch | Pin template version |
+
+## CLI Commands
+
+```bash
+# Generate explanation
+stella advisory explain finding-abc123 \
+  --type full \
+  --plain-language \
+  --attest --sign
+
+# Replay explanation
+stella advisory replay expl-20251226-001
+
+# Verify explanation attestation
+stella attest verify expl-20251226-001.dsse.json
+
+# Check for divergence
+stella advisory replay expl-20251226-001 --detect-divergence
+```
+
+## Configuration
+
+```yaml
+advisoryAi:
+  explanation:
+    # Default explanation type
+    defaultType: Full
+
+    # Plain language by default
+    plainLanguage: true
+
+    # Maximum explanation length
+    maxLength: 4000
+
+    # Minimum citation rate for EvidenceBacked authority
+    minCitationRate: 0.80
+
+    # Generate attestation for each explanation
+    generateAttestation: true
+
+    # Sign attestations
+    signAttestation: true
+
+  # Determinism settings for replay
+  inference:
+    temperature: 0.0
+    seed: 42
+    maxTokens: 4096
+```
+
+## 3-Line Summary Format
+
+Every explanation includes a 3-line summary following the AI UX pattern:
+
+| Line | Purpose | Example |
+|------|---------|---------|
+| Line 1 | What changed / what is it | "Critical RCE in lodash affecting payment-service" |
+| Line 2 | Why it matters | "Reachable via /api/checkout with no WAF protection" |
+| Line 3 | Next action | "Upgrade to lodash@4.17.21 or add VEX exception" |
+
+## Error Handling
+
+### Generation Errors
+
+```json
+{
+  "error": "evidence_retrieval_failed",
+  "message": "Unable to retrieve SBOM for artifact sha256:abc...",
+  "recoverable": true,
+  "suggestion": "Ensure the artifact has been scanned before requesting explanation"
+}
+```
+
+### Validation Errors
+
+```json
+{
+  "error": "citation_verification_failed",
+  "message": "Citation [2] references evidence that no longer exists",
+  "invalidCitations": ["sbom:payment-service:lodash@4.17.20"],
+  "suggestion": "Re-generate explanation with current evidence"
+}
+```

+# LLM Provider Plugins
+
+> **Sprint:** SPRINT_20251226_019_AI_offline_inference
+> **Tasks:** OFFLINE-07, OFFLINE-08, OFFLINE-09
+
+This guide documents the LLM (Large Language Model) provider plugin architecture for AI-powered advisory analysis, explanations, and remediation planning.
+
+## Overview
+
+StellaOps supports multiple LLM backends through a unified plugin architecture:
+
+| Provider | Type | Use Case | Priority |
+|----------|------|----------|----------|
+| **llama-server** | Local | Airgap/Offline deployment | 10 (highest) |
+| **ollama** | Local | Development, edge deployment | 20 |
+| **openai** | Cloud | GPT-4o for high-quality output | 100 |
+| **claude** | Cloud | Claude Sonnet for complex reasoning | 100 |
+
+## Architecture
+
+### Plugin Interface
+
+```csharp
+public interface ILlmProviderPlugin : IAvailabilityPlugin

+
+## Usage
+
+### Dependency Injection
+
+```csharp
+// Program.cs or Startup.cs
+services.AddLlmProviderPlugins("etc/llm-providers");
+
+// Or with explicit configuration
+services.AddLlmProviderPlugins(catalog =>
+{
+    catalog.LoadConfigurationsFromDirectory("etc/llm-providers");
+    // Optionally register custom plugins
+    catalog.RegisterPlugin(new CustomLlmProviderPlugin());
+});
+```
+
+### Using the Provider Factory
+
+```csharp
+public class AdvisoryExplanationService
+{
+    private readonly ILlmProviderFactory _providerFactory;
+
+    public async Task<string> GenerateExplanationAsync(
+        string vulnerabilityId,
+        CancellationToken cancellationToken)
+    {
+        // Get the default (highest priority available) provider
+        var provider = _providerFactory.GetDefaultProvider();
+
+        var request = new LlmCompletionRequest
+        {
+            SystemPrompt = "You are a security analyst explaining vulnerabilities.",
+            UserPrompt = $"Explain {vulnerabilityId} in plain language.",
+            Temperature = 0,  // Deterministic
+            Seed = 42,        // Reproducible
+            MaxTokens = 2048
+        };
+
+        var result = await provider.CompleteAsync(request, cancellationToken);
+        return result.Content;
+    }
+}
+```
+
+### Provider Selection
+
+```csharp
+// Get specific provider
+var openaiProvider = _providerFactory.GetProvider("openai");
+var claudeProvider = _providerFactory.GetProvider("claude");
+var llamaProvider = _providerFactory.GetProvider("llama-server");
+
+// List available providers
+var available = _providerFactory.AvailableProviders;
+// Returns: ["llama-server", "ollama", "openai", "claude"]
+```
+
+### Automatic Fallback
+
+```csharp
+// Create a fallback provider that tries providers in order
+var fallbackProvider = new FallbackLlmProvider(
+    _providerFactory,
+    providerOrder: ["llama-server", "ollama", "openai", "claude"],
+    _logger);
+
+// Uses first available provider, falls back on failure
+var result = await fallbackProvider.CompleteAsync(request, cancellationToken);
+```
+
+### Streaming Responses
+
+```csharp
+var provider = _providerFactory.GetDefaultProvider();
+
+await foreach (var chunk in provider.CompleteStreamAsync(request, cancellationToken))
+{
+    Console.Write(chunk.Content);
+
+    if (chunk.IsFinal)
+    {
+        Console.WriteLine($"\n[Finished: {chunk.FinishReason}]");
+    }
+}
+```
+
+## Determinism Requirements
+
+For reproducible AI outputs (required for attestations):
+
+| Setting | Value | Purpose |
+|---------|-------|---------|
+| `temperature` | `0.0` | No randomness in token selection |
+| `seed` | `42` | Fixed random seed |
+| `topK` | `1` | Single token selection (optional) |
+
+```yaml
+inference:
+  temperature: 0.0
+  seed: 42
+  topK: 1  # Most deterministic
+```
+
+**Verification:**
+
+```csharp
+var result = await provider.CompleteAsync(request, cancellationToken);
+
+if (!result.Deterministic)
+{
+    _logger.LogWarning("Output may not be reproducible");
+}
+```
+
+## Offline/Airgap Deployment
+
+### Recommended Configuration
+
+```
+etc/llm-providers/
+  llama-server.yaml    # Primary - enabled, priority: 10
+  ollama.yaml          # Backup - enabled, priority: 20
+  openai.yaml          # Disabled or missing
+  claude.yaml          # Disabled or missing
+```
+
+### Model Bundle Verification
+
+For airgap environments, use signed model bundles:
+
+```yaml
+# llama-server.yaml
+bundle:
+  bundlePath: "/bundles/llama3-8b.stellaops-model"
+  verifySignature: true
+  cryptoScheme: "ed25519"
+
+model:
+  expectedDigest: "sha256:abc123..."
+```
+
+**Creating a model bundle:**
+
+```bash
+# Create signed bundle
+stella model bundle \
+  --model /models/llama-3-8b-instruct.Q4_K_M.gguf \
+  --sign \
+  --output /bundles/llama3-8b.stellaops-model
+
+# Verify bundle
+stella model verify /bundles/llama3-8b.stellaops-model
+```
+
+## Custom Plugins
+
+To add support for a new LLM provider:
+
+```csharp
+public sealed class CustomLlmProviderPlugin : ILlmProviderPlugin
+{
+    public string Name => "Custom LLM Provider";
+    public string ProviderId => "custom";
+    public string DisplayName => "Custom LLM";
+    public string Description => "Custom LLM backend";
+    public string DefaultConfigFileName => "custom.yaml";
+
+    public bool IsAvailable(IServiceProvider services) => true;
+
+    public ILlmProvider Create(IServiceProvider services, IConfiguration configuration)
+    {
+        var config = CustomConfig.FromConfiguration(configuration);
+        var httpClientFactory = services.GetRequiredService<IHttpClientFactory>();
+        var logger = services.GetRequiredService<ILogger<CustomLlmProvider>>();
+        return new CustomLlmProvider(httpClientFactory.CreateClient(), config, logger);
+    }
+
+    public LlmProviderConfigValidation ValidateConfiguration(IConfiguration configuration)
+    {
+        // Validate configuration
+        return LlmProviderConfigValidation.Success();
+    }
+}
+```
+
+Register the custom plugin:
+
+```csharp
+services.AddLlmProviderPlugins(catalog =>
+{
+    catalog.RegisterPlugin(new CustomLlmProviderPlugin());
+    catalog.LoadConfigurationsFromDirectory("etc/llm-providers");
+});
+```
+
+## Telemetry
+
+LLM operations emit structured logs:
+
+```json
+{
+  "timestamp": "2025-12-26T10:30:00Z",
+  "operation": "llm_completion",
+  "providerId": "llama-server",
+  "model": "llama3-8b-q4km",
+  "inputTokens": 1234,
+  "outputTokens": 567,
+  "totalTimeMs": 2345,
+  "deterministic": true,
+  "finishReason": "stop"
+}
+```
+
+## Performance Comparison
+
+| Provider | Latency (TTFT) | Throughput | Cost | Offline |
+|----------|---------------|------------|------|---------|
+| **llama-server** | 50-200ms | 20-50 tok/s | Free | Yes |
+| **ollama** | 100-500ms | 15-40 tok/s | Free | Yes |
+| **openai (gpt-4o)** | 200-500ms | 50-100 tok/s | $$$ | No |
+| **claude (sonnet)** | 300-600ms | 40-80 tok/s | $$$ | No |
+
+*Note: Local performance depends heavily on hardware (GPU, RAM, CPU).*
+
+## Troubleshooting
+
+### Provider Not Available
+
+```
+InvalidOperationException: No LLM providers are available.
+```
+
+**Solutions:**
+1. Check configuration files exist in `etc/llm-providers/`
+2. Verify API keys are set (environment variables or config)
+3. For local providers, ensure server is running:
+   ```bash
+   # llama-server
+   curl http://localhost:8080/health
+
+   # ollama
+   curl http://localhost:11434/api/tags
+   ```
+
+### Non-Deterministic Output
+
+```
+Warning: Output may not be reproducible
+```
+
+**Solutions:**
+1. Set `temperature: 0.0` in configuration
+2. Set `seed: 42` (or any fixed value)
+3. Use the same model version across environments
+
+### Timeout Errors
+
+```
+TaskCanceledException: The request was canceled due to timeout.
+```
+
+**Solutions:**
+1. Increase `request.timeout` in configuration
+2. For local inference, ensure sufficient hardware resources
+3. Reduce `maxTokens` if appropriate

+# Offline AI Model Bundles
+
+> **Sprint:** SPRINT_20251226_019_AI_offline_inference
+> **Task:** OFFLINE-23, OFFLINE-26
+
+This guide covers transferring and configuring AI model bundles for air-gapped deployments.
+
+## Overview
+
+Local LLM inference in air-gapped environments requires model weight bundles to be transferred via sneakernet (USB, portable media, or internal package servers). The AdvisoryAI module supports deterministic local inference with signed model bundles.
+
+## Model Bundle Format
+
+```
+/offline/models/<model-id>/
+  ├── manifest.json           # Bundle metadata + file digests
+  ├── signature.dsse          # DSSE envelope with model signature
+  ├── weights/
+  │   ├── model.gguf          # Quantized weights (llama.cpp format)
+  │   └── model.gguf.sha256   # SHA-256 digest
+  ├── tokenizer/
+  │   ├── tokenizer.json      # Tokenizer config
+  │   └── special_tokens.json # Special tokens map
+  └── config/
+      ├── model_config.json   # Model architecture config
+      └── inference.json      # Recommended inference settings
+```
+
+## Manifest Schema
+
+```json
+{
+  "bundle_id": "llama3-8b-q4km-v1",
+  "model_family": "llama3",
+  "model_size": "8B",
+  "quantization": "Q4_K_M",
+  "license": "Apache-2.0",
+  "created_at": "2025-12-26T00:00:00Z",
+  "files": [
+    {
+      "path": "weights/model.gguf",
+      "digest": "sha256:a1b2c3d4e5f6...",
+      "size": 4893456789
+    },
+    {
+      "path": "tokenizer/tokenizer.json",
+      "digest": "sha256:1a2b3c4d5e6f...",
+      "size": 1842
+    }
+  ],
+  "crypto_scheme": "ed25519",
+  "signature_id": "ed25519-20251226-a1b2c3d4"
+}
+```
+
+## Transfer Workflow
+
+### 1. Export on Connected Machine
+
+```bash
+# Pull model from registry and create signed bundle
+stella model pull llama3-8b-q4km --offline --output /mnt/usb/models/
+
+# Verify bundle before transfer
+stella model verify /mnt/usb/models/llama3-8b-q4km/ --verbose
+```
+
+### 2. Transfer Verification
+
+Before physically transferring the media, verify the bundle integrity:
+
+```bash
+# Generate transfer manifest with all digests
+stella model export-manifest /mnt/usb/models/ --output transfer-manifest.json
+
+# Print weights digest for phone/radio verification
+sha256sum /mnt/usb/models/llama3-8b-q4km/weights/model.gguf
+# Example output: a1b2c3d4... model.gguf
+
+# Cross-check against manifest
+jq '.files[] | select(.path | contains("model.gguf")) | .digest' manifest.json
+```
+
+### 3. Import on Air-Gapped Host
+
+```bash
+# Import with signature verification
+stella model import /mnt/usb/models/llama3-8b-q4km/ \
+  --verify-signature \
+  --destination /var/lib/stellaops/models/
+
+# Verify loaded model matches expected digest
+stella model info llama3-8b-q4km --verify
+
+# List all installed models
+stella model list
+```
+
+## CLI Model Commands
+
+| Command | Description |
+|---------|-------------|
+| `stella model list` | List installed model bundles |
+| `stella model pull --offline` | Download bundle to local path for transfer |
+| `stella model verify <path>` | Verify bundle integrity and signature |
+| `stella model import <path>` | Import bundle from external media |
+| `stella model info <model-id>` | Display bundle details and verification status |
+| `stella model remove <model-id>` | Remove installed model bundle |
+
+### Command Examples
+
+```bash
+# List models with details
+stella model list --verbose
+
+# Pull specific model variant
+stella model pull llama3-8b --quantization Q4_K_M --offline --output ./bundle/
+
+# Verify all installed bundles
+stella model verify --all
+
+# Get model info including signature status
+stella model info llama3-8b-q4km --show-signature
+
+# Remove model bundle
+stella model remove llama3-8b-q4km --force
+```
+
+## Configuration
+
+### Local Inference Configuration
+
+Configure in `etc/advisory-ai.yaml`:
+
+```yaml
+advisoryAi:
+  inference:
+    mode: Local  # Local | Remote
+    local:
+      bundlePath: /var/lib/stellaops/models/llama3-8b-q4km
+      requiredDigest: "sha256:a1b2c3d4e5f6..."
+      verifySignature: true
+      deviceType: CPU  # CPU | GPU | NPU
+
+      # Determinism settings (required for replay)
+      contextLength: 4096
+      temperature: 0.0
+      seed: 42
+
+      # Performance tuning
+      threads: 4
+      batchSize: 512
+      gpuLayers: 0  # 0 = CPU only
+```
+
+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `ADVISORYAI_INFERENCE_MODE` | `Local` or `Remote` | `Local` |
+| `ADVISORYAI_MODEL_PATH` | Path to model bundle | `/var/lib/stellaops/models` |
+| `ADVISORYAI_MODEL_VERIFY` | Verify signature on load | `true` |
+| `ADVISORYAI_INFERENCE_THREADS` | CPU threads for inference | `4` |
+
+## Hardware Requirements
+
+| Model Size | Quantization | RAM Required | GPU VRAM | Inference Speed |
+|------------|--------------|--------------|----------|-----------------|
+| 7-8B | Q4_K_M | 8 GB | N/A (CPU) | ~10 tokens/sec |
+| 7-8B | FP16 | 16 GB | 8 GB | ~50 tokens/sec |
+| 13B | Q4_K_M | 16 GB | N/A (CPU) | ~5 tokens/sec |
+| 13B | FP16 | 32 GB | 16 GB | ~30 tokens/sec |
+
+### Recommended Configurations
+
+**Minimal (CPU-only, 8GB RAM):**
+- Model: Llama 3 8B Q4_K_M
+- Settings: `threads: 4`, `batchSize: 256`
+- Expected: ~10 tokens/sec
+
+**Standard (CPU, 16GB RAM):**
+- Model: Llama 3 8B Q4_K_M or 13B Q4_K_M
+- Settings: `threads: 8`, `batchSize: 512`
+- Expected: ~15-20 tokens/sec (8B), ~5-8 tokens/sec (13B)
+
+**GPU-Accelerated (8GB VRAM):**
+- Model: Llama 3 8B FP16
+- Settings: `gpuLayers: 35`, `batchSize: 512`
+- Expected: ~50 tokens/sec
+
+## Signing and Verification
+
+### Model Bundle Signing
+
+Bundles are signed using DSSE (Dead Simple Signing Envelope) format:
+
+```json
+{
+  "payloadType": "application/vnd.stellaops.model-bundle+json",
+  "payload": "<base64-encoded-manifest-digest>",
+  "signatures": [
+    {
+      "keyId": "stellaops-model-signer-2025",
+      "sig": "<base64-signature>"
+    }
+  ]
+}
+```
+
+### Regional Crypto Support
+
+| Region | Algorithm | Key Type |
+|--------|-----------|----------|
+| Default | Ed25519 | Ed25519 |
+| FIPS (US) | ECDSA-P256 | NIST P-256 |
+| GOST (RU) | GOST 34.10-2012 | GOST R 34.10-2012 |
+| SM (CN) | SM2 | SM2 |
+
+### Verification at Load Time
+
+When a model is loaded, the following checks occur:
+
+1. **Signature verification**: DSSE envelope is verified against known keys
+2. **Manifest integrity**: All file digests are recalculated and compared
+3. **Bundle completeness**: All required files are present
+4. **Configuration validation**: Inference settings are within safe bounds
+
+## Deterministic Inference
+
+For reproducible AI outputs (required for attestation replay):
+
+```yaml
+advisoryAi:
+  inference:
+    local:
+      # CRITICAL: These settings ensure deterministic output
+      temperature: 0.0
+      seed: 42
+      topK: 1
+      topP: 1.0
+```
+
+With these settings, the same prompt will produce identical output across runs, enabling:
+- AI artifact replay for compliance audits
+- Divergence detection between environments
+- Attestation verification
+
+## Benchmarking
+
+Run local inference benchmarks:
+
+```bash
+# Run standard benchmark suite
+stella model benchmark llama3-8b-q4km --iterations 10
+
+# Output includes:
+# - Latency: mean, median, p95, p99, TTFT
+# - Throughput: tokens/sec, requests/min
+# - Resource usage: peak memory, CPU utilization
+```
+
+## Troubleshooting
+
+| Symptom | Cause | Resolution |
+|---------|-------|------------|
+| `signature verification failed` | Bundle tampered or wrong key | Re-download bundle, verify chain of custody |
+| `digest mismatch` | Corrupted during transfer | Re-copy from source, verify SHA-256 |
+| `model not found` | Wrong bundle path | Check `bundlePath` in config |
+| `out of memory` | Model too large | Use smaller quantization (Q4_K_M) |
+| `inference timeout` | CPU too slow | Increase timeout or enable GPU |
+| `non-deterministic output` | Wrong settings | Set `temperature: 0`, `seed: 42` |

+## Usage
+
+### Dependency Injection
+
+```csharp
+// In Startup.cs or Program.cs
+services.AddScmConnectors(config =>
+{
+    // Optionally add custom plugins
+    config.AddPlugin(new CustomScmConnectorPlugin());
+
+    // Or remove built-in plugins
+    config.RemovePlugin("github");
+});
+```
+
+### Creating a Connector
+
+```csharp
+public class RemediationService
+{
+    private readonly ScmConnectorCatalog _catalog;
+
+    public async Task<PrCreateResult> CreateRemediationPrAsync(
+        string repositoryUrl,
+        RemediationPlan plan,
+        CancellationToken cancellationToken)
+    {
+        var options = new ScmConnectorOptions
+        {
+            ApiToken = _configuration["ScmToken"],
+            BaseUrl = _configuration["ScmBaseUrl"]
+        };
+
+        // Auto-detect connector from URL
+        var connector = _catalog.GetConnectorForRepository(repositoryUrl, options);
+        if (connector is null)
+            throw new InvalidOperationException($"No connector available for {repositoryUrl}");
+
+        // Create branch
+        var branchResult = await connector.CreateBranchAsync(
+            owner: "myorg",
+            repo: "myrepo",
+            branchName: $"stellaops/remediation/{plan.Id}",
+            baseBranch: "main",
+            cancellationToken);
+
+        // Update files
+        foreach (var change in plan.FileChanges)
+        {
+            await connector.UpdateFileAsync(
+                owner: "myorg",
+                repo: "myrepo",
+                branch: branchResult.BranchName,
+                filePath: change.Path,
+                content: change.NewContent,
+                commitMessage: $"chore: apply remediation for {plan.FindingId}",
+                cancellationToken);
+        }
+
+        // Create PR
+        return await connector.CreatePullRequestAsync(
+            owner: "myorg",
+            repo: "myrepo",
+            headBranch: branchResult.BranchName,
+            baseBranch: "main",
+            title: $"[StellaOps] Remediation for {plan.FindingId}",
+            body: GeneratePrBody(plan),
+            cancellationToken);
+    }
+}
+```
+
+### Polling CI Status
+
+```csharp
+public async Task<CiState> WaitForCiAsync(
+    IScmConnector connector,
+    string owner,
+    string repo,
+    string commitSha,
+    TimeSpan timeout,
+    CancellationToken cancellationToken)
+{
+    var deadline = DateTime.UtcNow + timeout;
+
+    while (DateTime.UtcNow < deadline)
+    {
+        var status = await connector.GetCiStatusAsync(
+            owner, repo, commitSha, cancellationToken);
+
+        switch (status.OverallState)
+        {
+            case CiState.Success:
+            case CiState.Failure:
+            case CiState.Error:
+                return status.OverallState;
+
+            case CiState.Pending:
+            case CiState.Running:
+                await Task.Delay(TimeSpan.FromSeconds(30), cancellationToken);
+                break;
+        }
+    }
+
+    return CiState.Unknown;
+}
+```
+
+## CI State Mapping
+
+Different SCM platforms use different status values. The connector normalizes them:
+
+| Platform | Pending | Running | Success | Failure | Error |
+|----------|---------|---------|---------|---------|-------|
+| **GitHub** | `pending`, `queued` | `in_progress` | `success` | `failure` | `error`, `cancelled` |
+| **GitLab** | `pending`, `waiting` | `running` | `success` | `failed` | `canceled`, `skipped` |
+| **Azure DevOps** | `notStarted`, `postponed` | `inProgress` | `succeeded` | `failed` | `canceled` |
+| **Gitea** | `pending`, `queued` | `running` | `success` | `failure` | `cancelled`, `timed_out` |
+
+## URL Auto-Detection
+
+The `CanHandle` method on each plugin detects repository URLs:
+
+| Plugin | URL Patterns |
+|--------|--------------|
+| **GitHub** | `github.com`, `github.` |
+| **GitLab** | `gitlab.com`, `gitlab.` |
+| **Azure DevOps** | `dev.azure.com`, `visualstudio.com`, `azure.com` |
+| **Gitea** | `gitea.`, `forgejo.`, `codeberg.org` |
+
+Example:
+```csharp
+// Auto-detects GitHub
+var connector = catalog.GetConnectorForRepository(
+    "https://github.com/myorg/myrepo", options);
+
+// Auto-detects GitLab
+var connector = catalog.GetConnectorForRepository(
+    "https://gitlab.com/mygroup/myproject", options);
+```
+
+## Custom Plugins
+
+To add support for a new SCM platform:
+
+```csharp
+public sealed class BitbucketScmConnectorPlugin : IScmConnectorPlugin
+{
+    public string ScmType => "bitbucket";
+    public string DisplayName => "Bitbucket";
+
+    public bool IsAvailable(ScmConnectorOptions options) =>
+        !string.IsNullOrEmpty(options.ApiToken);
+
+    public bool CanHandle(string repositoryUrl) =>
+        repositoryUrl.Contains("bitbucket.org", StringComparison.OrdinalIgnoreCase);
+
+    public IScmConnector Create(ScmConnectorOptions options, HttpClient httpClient) =>
+        new BitbucketScmConnector(httpClient, options);
+}
+
+public sealed class BitbucketScmConnector : ScmConnectorBase
+{
+    // Implement abstract methods...
+}
+```
+
+Register the custom plugin:
+```csharp
+services.AddScmConnectors(config =>
+{
+    config.AddPlugin(new BitbucketScmConnectorPlugin());
+});
+```
+
+## Error Handling
+
+All connector methods return result objects with `Success` and `ErrorMessage`:
+
+```csharp
+var result = await connector.CreateBranchAsync(...);
+
+if (!result.Success)
+{
+    _logger.LogError("Failed to create branch: {Error}", result.ErrorMessage);
+    return;
+}
+
+// Continue with successful result
+var branchSha = result.CommitSha;
+```
+
+## Security Considerations
+
+1. **Token Storage**: Never store tokens in configuration files. Use environment variables or secret management.
+
+2. **Minimum Permissions**: Request only required scopes for each platform.
+
+3. **TLS Verification**: Always verify TLS certificates in production (`verifySsl: true`).
+
+4. **Audit Logging**: All SCM operations are logged for compliance.
+
+5. **Repository Access**: Connectors only access repositories explicitly provided. No enumeration of accessible repos.
+
+## Telemetry
+
+SCM operations emit structured logs:
+
+```json
+{
+  "timestamp": "2025-12-26T10:30:00Z",
+  "operation": "scm_create_pr",
+  "scmType": "github",
+  "owner": "myorg",
+  "repo": "myrepo",
+  "branch": "stellaops/remediation/plan-123",
+  "duration_ms": 1234,
+  "success": true,
+  "pr_number": 456,
+  "pr_url": "https://github.com/myorg/myrepo/pull/456"
+}
+```

+**E) Binary Vulnerability Lookup (Sprint 20251226_014_BINIDX)**
+
+The **BinaryLookupStageExecutor** enriches scan results with binary-level vulnerability evidence:
+
+* **Identity Extraction**: For each ELF/PE/Mach-O binary, extract Build-ID, file SHA256, and architecture. Generate a `binary_key` for catalog lookups.
+* **Build-ID Catalog Lookup**: Query the BinaryIndex known-build catalog using Build-ID as primary key. Returns CVE matches with high confidence (>=0.95) when the exact binary version is indexed.
+* **Fingerprint Matching**: For binaries not in the catalog, compute position-independent fingerprints (basic-block, CFG, string-refs) and match against the vulnerability corpus. Returns similarity scores and confidence.
+* **Fix Status Detection**: For each CVE match, query distro-specific backport information to determine if the vulnerability was fixed via distro patch. Methods: `changelog`, `patch_analysis`, `advisory`.
+* **Valkey Cache**: All lookups are cached with configurable TTL (default 1 hour for identities, 30 minutes for fingerprints). Target cache hit rate: >80% for repeat scans.
+
+**BinaryFindingMapper** converts matches to standard findings format with `BinaryFindingEvidence`:
+```csharp
+public sealed record BinaryFindingEvidence
+{
+    public required string BinaryKey { get; init; }
+    public string? BuildId { get; init; }
+    public required string MatchMethod { get; init; }  // buildid_catalog, fingerprint_match, range_match
+    public required decimal Confidence { get; init; }
+    public string? FixedVersion { get; init; }
+    public string? FixStatus { get; init; }  // fixed, vulnerable, not_affected, wontfix
+}
+```
+
+**Proof Segments**: The **Attestor** generates `binary_fingerprint_evidence` proof segments with DSSE signatures for each binary with vulnerability matches. Schema: `https://stellaops.dev/predicates/binary-fingerprint-evidence@v1`.
+
+**UI Badges**: Scan results display status badges:
+* **Backported & Safe** (green): Distro backported the fix
+* **Affected & Reachable** (red): Vulnerable and in code path
+* **Unknown** (gray): Could not determine status
+
+**CLI Commands** (Sprint 20251226_014):
+* `stella binary inspect <file>`: Extract identity (Build-ID, hashes, architecture)
+* `stella binary lookup <build-id>`: Query vulnerabilities by Build-ID
+* `stella binary fingerprint <file>`: Generate position-independent fingerprint
+
+**F) Attestation & SBOM bind (optional)**
 
 * For each **file hash** or **binary hash**, query local cache of **Rekor v2** indices; if an SBOM attestation is found for **exact hash**, bind it to the component (origin=`attested`).
-* For the **image** digest, likewise bind SBOM attestations (build‑time referrers).
+* For the **image** digest, likewise bind SBOM attestations (build-time referrers).

+
+## Overview
+
+Binary Evidence provides vulnerability detection for compiled binaries (ELF, PE, Mach-O) beyond traditional package-based scanning. It identifies vulnerabilities in stripped binaries where package metadata may be missing or inaccurate, and detects when distribution maintainers have backported security fixes.
+
+### Key Features
+
+- **Build-ID Catalog Lookup**: High-confidence matching using GNU Build-IDs
+- **Fingerprint Matching**: Position-independent code matching for stripped binaries
+- **Backport Detection**: Identifies distribution-patched binaries
+- **Cryptographic Evidence**: DSSE-signed proof segments for audit trails
+
+---
+
+## CLI Commands
+
+### Inspect Binary Identity
+
+Extract identity information from a binary file:
+
+```bash
+stella binary inspect /path/to/binary
+
+# JSON output
+stella binary inspect /path/to/binary --format json
+```
+
+**Output:**
+```
+Binary Identity
+  Format:       ELF
+  Architecture: x86_64
+  Build-ID:     8d8f09a0d7e2c1b3a5f4e6d8c0b2a4e6f8d0c2b4
+  SHA256:       sha256:abcd1234567890abcdef1234567890abcdef1234...
+  Binary Key:   openssl:1.1.1w-1
+```
+
+### Lookup Vulnerabilities by Build-ID
+
+Query the vulnerability database using a Build-ID:
+
+```bash
+stella binary lookup 8d8f09a0d7e2c1b3a5f4e6d8c0b2a4e6f8d0c2b4
+
+# With distribution context
+stella binary lookup 8d8f09a0d7e2c1b3a5f4e6d8c0b2a4e6f8d0c2b4 \
+  --distro debian --release bookworm
+
+# JSON output
+stella binary lookup 8d8f09a0d7e2c1b3a5f4e6d8c0b2a4e6f8d0c2b4 --format json
+```
+
+**Output:**
+```
+Vulnerability Matches for Build-ID: 8d8f09a0d7e2c1b3a5f4...
+
+CVE-2023-5678
+  Status:     FIXED (Backported)
+  Package:    pkg:deb/debian/openssl@1.1.1n-0+deb11u4
+  Method:     buildid_catalog
+  Confidence: 95%
+  Fixed In:   1.1.1w-1
+
+CVE-2023-4807
+  Status:     FIXED (Backported)
+  Package:    pkg:deb/debian/openssl@1.1.1n-0+deb11u4
+  Method:     buildid_catalog
+  Confidence: 92%
+  Fixed In:   1.1.1w-1
+```
+
+### Generate Binary Fingerprint
+
+Create a position-independent fingerprint for matching:
+
+```bash
+stella binary fingerprint /path/to/binary
+
+# Specific algorithm
+stella binary fingerprint /path/to/binary --algorithm cfg
+
+# Fingerprint specific function
+stella binary fingerprint /path/to/binary --function SSL_read
+
+# Hex output
+stella binary fingerprint /path/to/binary --format hex
+```
+
+**Algorithms:**
+- `combined` (default): Combines all methods for robust matching
+- `basic-block`: Basic block hashes (good for minor changes)
+- `cfg`: Control flow graph structure (resilient to reordering)
+- `string-refs`: String constant references (fast, less precise)
+
+---
+
+## Understanding Scan Results
+
+### Status Badges
+
+When viewing scan results in the UI or CLI, binaries display status badges:
+
+| Badge | Color | Meaning |
+|-------|-------|---------|
+| **Backported & Safe** | Green | The distribution backported the security fix. The binary is not vulnerable despite the CVE matching. |
+| **Affected & Reachable** | Red | The binary contains vulnerable code and is in an executable code path. |
+| **Affected (Low Priority)** | Orange | Vulnerable but not in the main execution path. |
+| **Unknown** | Gray | Could not determine vulnerability or fix status. |
+
+### Match Methods
+
+Vulnerability matches use different detection methods with varying confidence:
+
+| Method | Confidence | Description |
+|--------|------------|-------------|
+| `buildid_catalog` | High (95%+) | Exact Build-ID match in the known-build catalog |
+| `fingerprint_match` | Medium (70-90%) | Position-independent code similarity |
+| `range_match` | Low (50-70%) | Version range inference |
+
+### Fix Status Detection
+
+Fix status is determined by analyzing:
+
+1. **Changelog**: Parsing distribution changelogs for CVE mentions
+2. **Patch Analysis**: Comparing function signatures pre/post patch
+3. **Advisory**: Cross-referencing distribution security advisories
+
+---
+
+## Configuration
+
+### Enabling Binary Analysis
+
+In `scanner.yaml`:
+
+```yaml
+scanner:
+  analyzers:
+    binary:
+      enabled: true
+      fingerprintOnMiss: true  # Generate fingerprints when catalog miss
+  binaryIndex:
+    enabled: true
+    batchSize: 100
+    timeoutMs: 5000
+    minConfidence: 0.7
+    cache:
+      enabled: true
+      identityTtl: 1h
+      fixStatusTtl: 1h
+      fingerprintTtl: 30m
+```
+
+### Cache Configuration
+
+Binary lookups are cached in Valkey for performance:
+
+```yaml
+binaryIndex:
+  cache:
+    keyPrefix: "stellaops:binary:"
+    identityTtl: 1h        # Cache Build-ID lookups
+    fixStatusTtl: 1h       # Cache fix status queries
+    fingerprintTtl: 30m    # Shorter TTL for fingerprints
+    targetHitRate: 0.80    # Target 80% cache hit rate
+```
+
+---
+
+## Interpreting Evidence
+
+### Binary Fingerprint Evidence Proof Segment
+
+Each binary with vulnerability matches generates a `binary_fingerprint_evidence` proof segment:
+
+```json
+{
+  "predicateType": "https://stellaops.dev/predicates/binary-fingerprint-evidence@v1",
+  "version": "1.0.0",
+  "binary_identity": {
+    "format": "elf",
+    "build_id": "8d8f09a0d7e2c1b3a5f4e6d8c0b2a4e6f8d0c2b4",
+    "file_sha256": "sha256:abcd1234...",
+    "architecture": "x86_64",
+    "binary_key": "openssl:1.1.1w-1",
+    "path": "/usr/lib/x86_64-linux-gnu/libssl.so.1.1"
+  },
+  "layer_digest": "sha256:layer1abc123...",
+  "matches": [
+    {
+      "cve_id": "CVE-2023-5678",
+      "method": "buildid_catalog",
+      "confidence": 0.95,
+      "vulnerable_purl": "pkg:deb/debian/openssl@1.1.1n-0+deb11u4",
+      "fix_status": {
+        "state": "fixed",
+        "fixed_version": "1.1.1w-1",
+        "method": "changelog",
+        "confidence": 0.98
+      }
+    }
+  ]
+}
+```
+
+### Viewing Proof Chain
+
+In the UI, click "View Proof Chain" on any CVE match to see:
+
+1. The binary identity used for lookup
+2. The match method and confidence
+3. The fix status determination method
+4. The DSSE signature and Rekor log entry (if enabled)
+
+---
+
+## Troubleshooting
+
+### No Matches Found
+
+If binaries show no vulnerability matches:
+
+1. **Check Build-ID**: Run `stella binary inspect` to verify the binary has a Build-ID
+2. **Verify Catalog Coverage**: Not all binaries are in the known-build catalog
+3. **Enable Fingerprinting**: Set `fingerprintOnMiss: true` to fall back to fingerprint matching
+
+### Low Confidence Matches
+
+Matches below the `minConfidence` threshold (default 0.7) are not reported. To see all matches:
+
+```bash
+stella binary lookup <build-id> --min-confidence 0.5
+```
+
+### Cache Issues
+
+Clear the binary cache if results seem stale:
+
+```bash
+# Via CLI
+stella cache clear --prefix binary
+
+# Via Redis CLI
+redis-cli KEYS "stellaops:binary:*" | xargs redis-cli DEL
+```
+
+### Build-ID Missing
+
+Stripped binaries may lack Build-IDs. Options:
+
+1. Rebuild with `-Wl,--build-id=sha1`
+2. Use fingerprint matching instead
+3. Map to package using file path heuristics
+
+---
+
+## Best Practices
+
+1. **Include Build-IDs**: Ensure your build pipeline preserves GNU Build-IDs
+2. **Use Distro Context**: Always specify `--distro` and `--release` for accurate backport detection
+3. **Review Unknown Status**: Investigate binaries with "Unknown" status manually
+4. **Monitor Cache Hit Rate**: Target >80% for repeat scans

+# StellaOps Configuration Guide
+
+This document describes the consolidated configuration structure for StellaOps deployments.
+
+## Directory Structure Overview
+
+All configuration lives under `etc/` at the repository root. This provides a single source of truth for all service configurations, trust anchors, crypto profiles, and plugin manifests.
+
+```

+├── vex/                  # VEX processing
+└── README.md             # This file
+```
+
+## Configuration Precedence
+
+Configuration values are resolved in the following order (highest priority first):
+
+1. **Command-line flags** - `--config-key=value`
+2. **Environment variables** - `STELLAOPS_<SERVICE>__<KEY>=value`
+3. **Active config file** - `etc/<service>/<service>.yaml`
+4. **Default values** - Built into the application
+
+### Environment Variable Naming
+
+Environment variables use double underscore (`__`) to represent nested configuration:
+
+```bash
+# Translates to: { "Scanner": { "Concurrency": { "MaxParallel": 8 } } }
+STELLAOPS_SCANNER__CONCURRENCY__MAXPARALLEL=8
+```
+
+## Service Configuration
+
+### File Naming Convention
+
+| File Pattern | Purpose |
+|--------------|---------|
+| `<service>.yaml` | Active configuration (git-ignored in production) |
+| `<service>.yaml.sample` | Documented template with all options |
+| `<service>.<profile>.yaml` | Profile-specific configuration |
+
+### Creating Active Configuration
+
+```bash
+# Copy sample to create active config
+cp etc/scanner/scanner.yaml.sample etc/scanner/scanner.yaml
+
+# Edit for your environment
+vi etc/scanner/scanner.yaml
+```
+

+      # Plugin binaries (read-only)
+      - ./plugins/scanner:/app/plugins/scanner:ro
+
+      # Runtime data (read-write)
+      - scanner-data:/var/lib/stellaops/scanner
+```
+
+### Environment File
+
+```yaml
+# docker-compose.yml
+services:
+  scanner:
+    env_file:
+      - ./etc/env/dev.env      # Copied from dev.env.sample
+```
+
+### Crypto Profile Overlays
+
+```bash
+# FIPS deployment
+docker compose -f docker-compose.yml -f devops/compose/docker-compose.fips.yml up
+
+# eIDAS deployment
+docker compose -f docker-compose.yml -f devops/compose/docker-compose.eidas.yml up
+
+# Air-gapped with Russian crypto
+docker compose -f docker-compose.yml \
+  -f devops/compose/docker-compose.airgap.yml \
+  -f devops/compose/docker-compose.russia.yml up
+```
+
+## Quick Start
+
+### 1. Initialize Configuration
+
+```bash
+# Clone sample configs
+./devops/scripts/init-config.sh dev
+
+# This copies all .sample files to active configs for development
+```
+
+### 2. Customize for Environment
+
+```bash
+# Edit main service configs
+vi etc/scanner/scanner.yaml
+vi etc/authority/authority.yaml
+
+# Set environment-specific values
+vi etc/env/dev.env
+```
+
+### 3. Select Crypto Profile (if needed)
+
+```bash
+# For US/FIPS compliance
+cp etc/crypto/profiles/us-fips/env.sample etc/crypto/profiles/us-fips/env
+export STELLAOPS_CRYPTO_PROFILE=us-fips
+```
+
+### 4. Start Services
+
+```bash
+docker compose up -d
+```
+
+## Configuration Validation
+
+```bash
+# Validate all configuration files
+./devops/scripts/validate-config.sh
+
+# Validate specific service
+./devops/scripts/validate-config.sh scanner
+
+# Validate policy packs against schema
+./devops/scripts/validate-policy-packs.sh
+```
+
+## Migration from Legacy Structure
+
+If upgrading from a deployment with the legacy multi-directory structure:
+
+| Legacy Location | New Location |
+|-----------------|--------------|
+| `certificates/` | `etc/certificates/` |
+| `config/env/.env.*` | `etc/crypto/profiles/*/env.sample` |
+| `config/crypto-profiles.sample.json` | `etc/crypto/crypto.yaml.sample` |
+| `policies/` | `etc/policy/` |
+| `etc/rootpack/` | `etc/crypto/profiles/` |
+
+See `docs/operations/configuration-migration.md` for detailed migration steps.
+
+## Security Considerations
+
+1. **Never commit active configs** - `.gitignore` excludes `*.yaml` (only `*.yaml.sample` committed)
+2. **Secrets via environment** - Use `STELLAOPS_*` env vars or external secret managers
+3. **Development secrets are clearly marked** - `etc/secrets/` contains only dev/sample keys
+4. **Production signing keys** - Should come from HSM, Vault, or KMS - never from files

+# Configuration Migration Guide
+
+This guide covers migrating from the legacy multi-directory configuration structure to the consolidated `etc/` structure.
+
+## Legacy vs New Structure
+
+### Files to Move
+
+| Legacy Location | New Location | Action |
+|-----------------|--------------|--------|
+| `certificates/*.pem` | `etc/certificates/trust-roots/` | Move |
+| `certificates/*-signing-*.pem` | `etc/certificates/signing/` | Move |
+| `config/env/.env.*.example` | `etc/crypto/profiles/*/env.sample` | Move + rename |
+| `config/crypto-profiles.sample.json` | Delete (superseded by `etc/crypto/`) | Delete |
+| `policies/` | `etc/policy/` | Move |
+| `etc/rootpack/*` | `etc/crypto/profiles/*` | Rename |
+
+### Directories to Remove After Migration
+
+```
+certificates/          # Moved to etc/certificates/
+config/                # Moved to etc/crypto/ and etc/env/
+policies/              # Moved to etc/policy/
+```
+
+### Directories That Stay
+
+```
+plugins/               # Runtime artifacts, not configuration
+opt/                   # Vendor packages
+offline/               # Air-gap operational data
+```
+
+## Migration Steps
+
+### Step 1: Backup Current Configuration
+
+```bash
+# Create backup
+tar -czvf config-backup-$(date +%Y%m%d).tar.gz \
+    certificates/ \
+    config/ \
+    policies/ \
+    etc/
+```
+
+### Step 2: Run Migration Script
+
+```bash
+./devops/scripts/migrate-config.sh
+```
+
+This script:
+1. Creates the new directory structure
+2. Moves files to new locations
+3. Updates path references
+4. Validates the migration
+
+### Step 3: Manual Migration (if script not available)
+
+```bash
+# Create new directories
+mkdir -p etc/certificates/trust-roots
+mkdir -p etc/certificates/signing
+mkdir -p etc/crypto/profiles/{cn,eu,kr,ru,us-fips}
+mkdir -p etc/env
+mkdir -p etc/policy/packs
+mkdir -p etc/policy/schemas
+
+# Move certificates
+mv certificates/*-bundle*.pem etc/certificates/trust-roots/
+mv certificates/*-root*.pem etc/certificates/trust-roots/
+mv certificates/*-signing-*.pem etc/certificates/signing/
+
+# Move crypto profiles
+mv etc/rootpack/cn/* etc/crypto/profiles/cn/
+mv etc/rootpack/eu/* etc/crypto/profiles/eu/
+mv etc/rootpack/kr/* etc/crypto/profiles/kr/
+mv etc/rootpack/ru/* etc/crypto/profiles/ru/
+mv etc/rootpack/us-fips/* etc/crypto/profiles/us-fips/
+
+# Move environment profiles
+mv config/env/.env.fips.example etc/crypto/profiles/us-fips/env.sample
+mv config/env/.env.eidas.example etc/crypto/profiles/eu/env.sample
+mv config/env/.env.ru-free.example etc/crypto/profiles/ru/env.sample
+mv config/env/.env.sm.example etc/crypto/profiles/cn/env.sample
+mv config/env/.env.kcmvp.example etc/crypto/profiles/kr/env.sample
+
+# Move policies
+mv policies/starter-day1.yaml etc/policy/packs/
+mv policies/schemas/* etc/policy/schemas/
+
+# Remove legacy directories
+rmdir etc/rootpack/cn etc/rootpack/eu etc/rootpack/kr etc/rootpack/ru etc/rootpack/us-fips etc/rootpack
+rmdir config/env config
+rmdir certificates
+rmdir policies/schemas policies
+```
+
+### Step 4: Update Docker Compose Files
+
+Update volume mounts in `devops/compose/docker-compose.*.yaml`:
+
+**Before:**
+```yaml
+volumes:
+  - ../../certificates:/etc/ssl/certs/stellaops:ro
+  - ../../config/crypto-profiles.json:/app/config/crypto-profiles.json:ro
+```
+
+**After:**
+```yaml
+volumes:
+  - ../../etc/certificates/trust-roots:/etc/ssl/certs/stellaops:ro
+  - ../../etc/crypto:/app/etc/crypto:ro
+```
+
+### Step 5: Update Environment References
+
+**Before:**
+```bash
+source config/env/.env.fips.example
+```
+
+**After:**
+```bash
+cp etc/crypto/profiles/us-fips/env.sample etc/crypto/profiles/us-fips/env
+source etc/crypto/profiles/us-fips/env
+```
+
+### Step 6: Validate Migration
+
+```bash
+# Validate configuration structure
+./devops/scripts/validate-config.sh
+
+# Test service startup
+docker compose up -d --dry-run
+```
+
+## Docker Compose Reference Updates
+
+### Scanner Service
+
+```yaml
+scanner:
+  volumes:
+    # Configuration
+    - ../../etc/scanner:/app/etc/scanner:ro
+    - ../../etc/certificates/trust-roots:/etc/ssl/certs/stellaops:ro
+    - ../../etc/crypto:/app/etc/crypto:ro
+
+    # Plugin binaries (stays at root)
+    - ../../plugins/scanner:/app/plugins/scanner:ro
+```
+
+### Authority Service
+
+```yaml
+authority:
+  volumes:
+    - ../../etc/authority:/app/etc/authority:ro
+    - ../../etc/certificates/signing:/app/etc/signing:ro
+```
+
+### Policy Gateway
+
+```yaml
+policy-gateway:
+  volumes:
+    - ../../etc/policy:/app/etc/policy:ro
+```
+
+## Environment Variable Changes
+
+### Crypto Profile Selection
+
+**Before:**
+```bash
+CRYPTO_PROFILE_PATH=/app/config/crypto-profiles.json
+CRYPTO_REGION=fips
+```
+
+**After:**
+```bash
+STELLAOPS_CRYPTO_PROFILE=us-fips
+# Profile loaded from: /app/etc/crypto/profiles/us-fips/crypto.profile.yaml
+```
+
+### Certificate Paths
+
+**Before:**
+```bash
+SSL_CERT_DIR=/etc/ssl/certs
+STELLAOPS_TRUST_ROOTS=/app/certificates
+```
+
+**After:**
+```bash
+STELLAOPS_CERTIFICATES__TRUSTROOTSDIR=/app/etc/certificates/trust-roots
+STELLAOPS_CERTIFICATES__SIGNINGDIR=/app/etc/certificates/signing
+```
+
+## Rollback Procedure
+
+If issues occur:
+
+```bash
+# Restore from backup
+tar -xzvf config-backup-*.tar.gz
+
+# Revert Docker Compose changes
+git checkout devops/compose/
+
+# Restart services
+docker compose down && docker compose up -d
+```

+- Triggered by: `channel: edge` or tag without `-stable`/`-lts`
+
+### Stable
+
+- Production-ready releases
+- Thoroughly tested
+- 9 months of support (feature releases)
+- Triggered by: `channel: stable`
+
+### LTS (Long Term Support)
+
+- April releases only (XX.04)
+- 5 years of security updates
+- 3 years of standard support
+- Triggered by: `channel: lts`
+
+---
+
+## Rollback Procedures
+
+### Container Rollback
+
+```bash
+# Pull previous version
+docker pull git.stella-ops.org/stella-ops.org/authority:2025.10
+
+# Update deployment
+kubectl set image deployment/authority authority=git.stella-ops.org/stella-ops.org/authority:2025.10
+```
+
+### Helm Rollback
+
+```bash
+# List releases
+helm history stellaops
+
+# Rollback to previous revision
+helm rollback stellaops 1
+```
+
+### Database Rollback
+
+1. Stop all services
+2. Restore database from backup
+3. Deploy previous version
+4. Verify data integrity
+
+**Important**: Always test rollback procedures in staging before production.
+
+---
+
+## Hotfix Process
+
+For critical security fixes:
+
+1. Create hotfix branch from release tag
+   ```bash
+   git checkout -b hotfix/2026.04.1 suite-2026.04
+   ```
+
+2. Apply fix and test
+
+3. Tag hotfix release
+   ```bash
+   git tag suite-2026.04.1
+   git push origin suite-2026.04.1
+   ```
+
+4. Cherry-pick fix to main branch
+
+---
+
+## Post-Release Tasks
+
+- [ ] Verify artifacts in registry
+- [ ] Update documentation site
+- [ ] Send release announcement
+- [ ] Update compatibility matrix
+- [ ] Monitor for issues (24-48 hours)
+- [ ] Update roadmap
+
+---
+
+## Troubleshooting
+
+### Build Failures
+
+1. Check test results in artifacts
+2. Review workflow logs
+3. Verify secrets are configured (GITEA_TOKEN)
+
+### Push Failures
+
+1. Verify registry authentication
+2. Check network connectivity
+3. Ensure no conflicting tags exist
+
+### Common Issues
+
+| Issue | Resolution |
+|-------|------------|
+| Tag already exists | Delete tag and recreate, or use next version |
+| NuGet push fails | Check package already exists, use `--skip-duplicate` |
+| Container push fails | Verify registry login, check image size limits |

+# StellaOps Versioning
+
+This document describes the versioning strategy for StellaOps releases.
+
+## Overview
+
+StellaOps uses a two-tier versioning system:
+
+1. **Suite Releases** - Ubuntu-style calendar versioning (YYYY.MM) with codenames
+2. **Module Releases** - Semantic versioning (MAJOR.MINOR.PATCH)
+
+---
+
+## Suite Versions (Ubuntu-style)
+
+### Format
+
+```
+YYYY.MM[-channel]
+```
+
+- **YYYY** - Four-digit year
+- **MM** - Month (always `04` or `10`)
+- **channel** - Optional: `edge`, `stable`, or `lts`
+
+### Examples
+
+| Version | Codename | Release Date | Type | Support |
+|---------|----------|--------------|------|---------|
+| 2026.04 | Nova | April 2026 | LTS | 5 years |
+| 2026.10 | Orion | October 2026 | Feature | 9 months |
+| 2027.04 | Pulsar | April 2027 | LTS | 5 years |
+| 2027.10 | Quasar | October 2027 | Feature | 9 months |
+
+### Release Cadence
+
+- **April releases (XX.04)** - Long Term Support (LTS)
+  - 5 years of security updates
+  - 3 years of standard support
+  - Recommended for production environments
+
+- **October releases (XX.10)** - Feature releases
+  - 9 months of support
+  - Latest features and improvements
+  - Recommended for development and testing
+
+### Codenames
+
+Codenames follow a celestial theme with alphabetical progression:
+
+| Letter | Codename | Celestial Object |
+|--------|----------|------------------|
+| N | Nova | Exploding star |
+| O | Orion | Constellation |
+| P | Pulsar | Rotating neutron star |
+| Q | Quasar | Distant active galaxy |
+| R | Rigel | Blue supergiant star |
+| S | Sirius | Brightest star |
+| T | Triton | Neptune's moon |
+| U | Umbra | Shadow region |
+| V | Vega | Fifth-brightest star |
+| W | Wezen | Delta Canis Majoris |
+
+See [codenames.md](codenames.md) for the complete registry.

+|---------|----------|--------------|----------|-------|
+| - | - | - | - | No releases yet |
+
+## Naming Conventions
+
+### Rules
+
+1. **Alphabetical progression** - Each release uses the next letter
+2. **Celestial theme** - All names relate to astronomical objects
+3. **Single word** - Keep codenames to one word
+4. **Pronounceable** - Names should be easy to say and remember
+5. **Unique** - No repeated codenames in the registry
+
+### Object Types
+
+| Category | Examples |
+|----------|----------|
+| Stars | Nova, Sirius, Vega, Rigel |
+| Constellations | Orion, Lyra, Cygnus |
+| Galaxies | Quasar, Andromeda |
+| Moons | Triton, Europa, Titan |
+| Phenomena | Umbra, Aurora, Zenith |
+| Neutron Stars | Pulsar, Magnetar |
+
+## Future Codenames (Reserved)
+
+Letters after W for future use:
+
+| Letter | Candidate | Object Type |
+|--------|-----------|-------------|
+| X | Xena | Dwarf planet (informal name for Eris) |
+| Y | Ymir | Saturn's moon |
+| Z | Zenith | Astronomical position |
+| A (cycle 2) | Andromeda | Galaxy |
+| B (cycle 2) | Betelgeuse | Star |
+| C (cycle 2) | Cygnus | Constellation |
+
+## Usage in Release Notes
+
+When referencing a release, use:
+
+```
+StellaOps 2026.04 "Nova"
+```
+
+Or in formal documentation:
+
+```
+StellaOps Suite Release 2026.04 (Codename: Nova)
+```
+
+## History
+
+The celestial naming theme was chosen to reflect:
+- **Reliability** - Like stars that guide navigation
+- **Scope** - The vast scale of supply chain security challenges
+- **Innovation** - Exploring new frontiers in software security

+# StellaOps Configuration (`etc/`)
+
+This directory contains all configuration for StellaOps services. It is the **single source of truth** for deployment configuration.
+

+
+## File Naming Convention
+
+| Pattern | Purpose | Git Status |
+|---------|---------|------------|
+| `*.yaml.sample` | Documented template with all options | Committed |
+| `*.yaml` | Active configuration | Git-ignored |
+| `*.env.sample` | Environment variable template | Committed |
+| `env.*` | Active environment file | Git-ignored |
+
+## Quick Start
+
+```bash
+# 1. Copy sample to active config
+cp etc/scanner/scanner.yaml.sample etc/scanner/scanner.yaml
+
+# 2. Edit for your environment
+vi etc/scanner/scanner.yaml
+
+# 3. Copy environment profile
+cp etc/env/dev.env.sample etc/env/dev.env
+```
+
+## Regional Crypto Profiles
+
+For compliance with regional cryptographic standards:
+
+| Profile | Standard | Use Case |
+|---------|----------|----------|
+| `us-fips` | FIPS 140-3 | US Federal, DoD |
+| `eu` | eIDAS | EU qualified signatures |
+| `ru` | GOST R 34.10/11/12 | Russian Federation |
+| `cn` | GM/T (SM2/SM3/SM4) | China |
+| `kr` | KCMVP | South Korea |
+
+Activate via:
+```bash
+export STELLAOPS_CRYPTO_PROFILE=us-fips
+```
+
+## What Lives Elsewhere
+
+| Directory | Purpose |
+|-----------|---------|
+| `plugins/` | Compiled plugin binaries (runtime artifacts) |
+| `opt/` | Optional vendor packages (CryptoPro, etc.) |
+| `offline/` | Air-gap operational state (feeds, packages) |
+
+## Security
+
+- **NEVER commit active configs** (`.yaml` files are git-ignored)
+- **Secrets via environment variables** or external secret managers
+- **`etc/secrets/`** contains ONLY development/sample keys - never for production
+- **Production signing keys** must come from HSM, Vault, or KMS

-## Purpose & Scope
-- Working directory: `policies/` (policy packs, overrides, and metadata).
-- Roles: policy engineer, QA, docs contributor.
-
-## Required Reading (treat as read before DOING)
-- `docs/README.md`
-- `docs/modules/policy/architecture.md`
-- `docs/policy/dsl-reference.md` (if present)
-- Relevant sprint file(s).
-
-## Working Agreements
-- Policy packs must be versioned and deterministic.
-- Use clear comments for default rules and override precedence.
-- Keep offline-friendly defaults; avoid network dependencies in policy evaluation examples.
-- When policy behavior changes, update corresponding docs under `docs/policy/`.
-
-## Validation
-- Validate policy YAML against schema when available.
-- Add/extend tests in Policy module to cover policy pack behavior.
