## Implementation Details
### Architectural Rules (from Advisory)
From advisory Section 2.5:
- **Lattice placement**: Lattice algorithms run in `scanner.webservice`, not in Concelier or Excititor
- **Preserve prune source**: Concelier and Excititor "preserve prune source" (do not evaluate lattice decisions)
- **Assembly boundaries**: Core libraries must not reference infrastructure; WebServices isolated from each other
### Architecture Test Example (NetArchTest.Rules)
```csharp
using NetArchTest.Rules;
using Xunit;
public sealed class LatticeEngineRulesTests
{
[Fact]
[UnitTest]
[ArchitectureTest]
public void ConcelierAssemblies_MustNotReference_ScannerLatticeEngine()
{
var result = Types.InAssemblies(GetConcelierAssemblies())
.ShouldNot()
.HaveDependencyOn("StellaOps.Scanner.Lattice")
.GetResult();
Assert.True(result.IsSuccessful,
$"Concelier must not reference Scanner lattice engine. Violations: {string.Join(", ", result.FailingTypeNames)}");
}
[Fact]
[UnitTest]
[ArchitectureTest]
public void ExcititorAssemblies_MustNotReference_ScannerLatticeEngine()
{
var result = Types.InAssemblies(GetExcititorAssemblies())
.ShouldNot()
.HaveDependencyOn("StellaOps.Scanner.Lattice")
.GetResult();
Assert.True(result.IsSuccessful,
$"Excititor must not reference Scanner lattice engine. Violations: {string.Join(", ", result.FailingTypeNames)}");
}
}
```
### Forbidden Package Rule Example
```csharp
[Fact]
[UnitTest]
[ArchitectureTest]
public void CoreLibraries_MustNotReference_Redis()
{
var result = Types.InAssemblies(GetCoreAssemblies())
.ShouldNot()
.HaveDependencyOn("StackExchange.Redis")
.GetResult();
Assert.True(result.IsSuccessful,
$"Core libraries must use Valkey-compatible clients only. Violations: {string.Join(", ", result.FailingTypeNames)}");
}
```
## Wave Coordination
- **Wave 1**: Test project setup and tooling
- **Wave 2**: Lattice placement rules (critical architectural constraint)
- **Wave 3**: Module dependency rules (layering enforcement)
- **Wave 4**: Forbidden package rules (compliance)
- **Wave 5**: Naming convention rules (consistency)
- **Wave 6**: CI integration and documentation
## Interlocks
- Architecture tests run in Unit lane (fast, PR-gating)
- Violations must be treated as build failures
- Exceptions require explicit architectural review and documentation
## Upcoming Checkpoints
- 2026-01-10: Architecture test project operational with lattice rules
- 2026-01-20: All dependency and forbidden package rules implemented
- 2026-01-25: CI integration complete (PR-gating)
## Action Tracker
| Date (UTC) | Action | Owner |
| --- | --- | --- |
| 2026-01-05 | Validate NetArchTest.Rules compatibility with .NET 10. | Platform Guild |
| 2026-01-10 | Review lattice placement rules with architecture team. | Platform Guild |
## Decisions & Risks
- **Decision**: Use NetArchTest.Rules for assembly dependency analysis.
- **Decision**: Architecture tests are PR-gating (Unit lane).
- **Decision**: Violations require architectural review; no "ignore" pragmas allowed.
- **Decision**: Lattice placement rule is the highest priority (prevents functional violations).
| Risk | Impact | Mitigation | Owner |
| --- | --- | --- | --- |
| False positives | Valid code blocked | Test rules thoroughly; allow explicit exceptions with documentation. | Platform Guild |
| Rules too restrictive | Development friction | Start with critical rules only; expand incrementally. | Platform Guild |
| NetArchTest.Rules compatibility | Tool doesn't support .NET 10 | Validate early; have fallback (custom Roslyn analyzer). | Platform Guild |

## Wave Coordination
- **Wave 1 (L0 Bundle + AN1 Analyzers):** Tasks 1-6.
- **Wave 2 (S1 Storage + W1 Controller):** Tasks 7-12.
- **Wave 3 (CLI1 Tools + Integration):** Tasks 13-17.
## Wave Detail Snapshots
- **Wave 1 evidence:** Bundle export/import tests passing; determinism tests passing; policy analyzer tests passing.
- **Wave 2 evidence:** Storage idempotency tests passing; controller API contract tests passing.
- **Wave 3 evidence:** CLI tool tests passing; integration tests (online → offline) passing.
## Interlocks
- Determinism tests depend on Sprint 5100.0007.0003 (Determinism gate).
- Storage tests depend on Sprint 5100.0007.0004 (Storage harness — PostgresFixture).
- WebService tests depend on Sprint 5100.0007.0006 (WebService fixture).
- Policy analyzer tests coordinate with Sprint 5100.0009.0004 (Policy tests).
## Upcoming Checkpoints
- 2026-09-17: Bundle and policy analyzer tests complete (Wave 1).
- 2026-10-01: Storage and controller API tests complete (Wave 2).
- 2026-10-15: CLI tool and integration tests complete (Wave 3).
## Action Tracker
| Date (UTC) | Action | Owner |
| --- | --- | --- |
| 2026-09-17 | Review bundle determinism tests and policy analyzer tests. | AirGap Guild + Policy Guild |
| 2026-10-01 | Review storage idempotency tests and controller API contract tests. | AirGap Guild |
| 2026-10-15 | Review CLI tool tests and online→offline integration tests. | AirGap Guild + Platform Guild |
## Decisions & Risks
- **Decision:** Bundle determinism is critical: same inputs → same bundle hash (SHA-256).
- **Decision:** Bundle export → import → re-export must produce identical bundle (roundtrip test).
- **Decision:** AirGap CLI tool follows same exit code conventions as main CLI (0=success, 1=user error, 2=system error).
- **Decision:** Integration tests verify full online→offline→online workflow.
| Risk | Impact | Mitigation | Owner |
| --- | --- | --- | --- |
| Bundle format changes break determinism | Tests fail unexpectedly | Explicit versioning for bundle format; deprecation warnings. | AirGap Guild |
| Policy analyzer compilation slow | Test suite timeout | Limit analyzer test scope; use caching. | Policy Guild |
| Integration tests require multiple environments | Test complexity | Use Docker Compose for multi-environment setup. | AirGap Guild |
| Bundle size too large | Import/export slow | Compression tests; size limit validation. | AirGap Guild |

# Sprint 8100.0011.0001 · Router SDK ASP.NET Endpoint Bridge
## Topic & Scope
Eliminate dual-route maintenance by treating **standard ASP.NET endpoint registration** (controllers/minimal APIs) as the single source of truth for Router endpoint registration. This sprint delivers:
1. **ASP.NET Endpoint Discovery**: Discover endpoints from `EndpointDataSource`, extract full metadata (authorization, parameters, responses, OpenAPI), and convert to Router `EndpointDescriptor`s.
2. **Router→ASP.NET Dispatch**: Execute incoming Router requests through the ASP.NET pipeline with full fidelity (filters, model binding, authorization).
3. **Authorization Mapping**: Convert ASP.NET authorization policies/roles to Router `ClaimRequirement`s automatically, with YAML override support.
4. **Program.cs Integration**: Provide opt-in extension methods (`AddStellaRouterBridge`, `UseStellaRouterBridge`) for seamless integration.
**Working directory:** `src/__Libraries/StellaOps.Microservice.AspNetCore/` (new), `src/__Libraries/__Tests/StellaOps.Microservice.AspNetCore.Tests/` (tests), plus one pilot service.
**Evidence:** Deterministic endpoint discovery with full ASP.NET metadata; Router requests execute ASP.NET endpoints with correct model binding, authorization, and filters; pilot service registers via bridge without `[StellaEndpoint]` duplicates.
---
## Dependencies & Concurrency
- **Depends on:** `docs/modules/router/aspnet-endpoint-bridge.md` (design), `StellaOps.Microservice` SDK, pilot service with maintained `AGENTS.md`.
- **Recommended to land before:** Sprint 8100.0011.0002 (Gateway identity header policy) and Sprint 8100.0011.0003 (Valkey messaging transport).
- **Safe to run in parallel with:** Transport wiring (0003) and header hardening (0002) as long as shared contracts remain stable.
---
## Documentation Prerequisites
- `docs/modules/router/architecture.md`
- `docs/modules/router/migration-guide.md`
- `docs/modules/router/aspnet-endpoint-bridge.md`
- `docs/modules/gateway/identity-header-policy.md`
---

| **OpenAPI** | `.WithDescription(...)` | ✓ Extract | N/A | `Description` |
| **OpenAPI** | `.WithTags(...)` | ✓ Extract | N/A | `Tags[]` |
| **Routing** | Route groups (`MapGroup`) | ✓ Compose paths | ✓ Match | Path prefix composition |
| **Routing** | Route constraints `{id:int}` | ✓ Normalize | ✓ Match | Stripped but semantics preserved |
| **Routing** | Catch-all `{**path}` | ✓ Normalize | ✓ Match | Explicit support |

## Decisions & Risks
### Decisions
| Decision | Rationale |
|----------|-----------|
| ASP.NET endpoint registration is single source of truth | Eliminates route drift, reduces maintenance |
| YAML overrides supplement (not replace) ASP.NET metadata | Allows security hardening without code changes |
| Use ASP.NET matcher for dispatch | Preserves constraint semantics, route precedence |
| Extract full OpenAPI metadata | Enables accurate Gateway OpenAPI aggregation |
| Require explicit authorization | Prevents accidental public exposure |
### Risks
| Risk | Impact | Mitigation | Owner |
|------|--------|------------|-------|
| Route matching drift vs ASP.NET | Incorrect routing | Use ASP.NET's own matcher; extensive tests | Router Guild |
| Missing authorization on bridged endpoints | Privilege escalation | `RequireExplicit` default; fail-fast | Platform Guild |
| Model binding failures | Request errors | Comprehensive parameter extraction; tests | Router Guild |
| Filter execution order | Incorrect behavior | Execute via standard `RequestDelegate`; tests | Router Guild |
| Performance overhead of synthetic HttpContext | Latency | Benchmark; pool contexts if needed | Platform Guild |
| Pilot selection blocked | Sprint stalls | Pre-identify pilot in Wave 0 | Project Mgmt |

# Sprint 8100.0012.0001 · Canonicalizer Versioning for Content-Addressed Identifiers
## Topic & Scope
Embed canonicalization version markers in content-addressed hashes to prevent future hash collisions when canonicalization logic evolves. This sprint delivers:
1. **Canonicalizer Version Constant**: Define `CanonVersion.V1 = "stella:canon:v1"` as a stable version identifier.
2. **Version-Prefixed Hashing**: Update `ContentAddressedIdGenerator` to include version marker in canonicalized payloads before hashing.
3. **Backward Compatibility**: Existing hashes remain valid; new hashes include version marker; verification can detect and handle both formats.
4. **Documentation**: Update architecture docs with canonicalization versioning rationale and upgrade path.
**Working directory:** `src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/`, `src/__Libraries/StellaOps.Canonical.Json/`, `src/__Libraries/__Tests/`.
**Evidence:** All content-addressed IDs include version marker; determinism tests pass; backward compatibility verified; no hash collisions between v0 (legacy) and v1 (versioned).
---
## Dependencies & Concurrency
- **Depends on:** None (foundational change).
- **Blocks:** Sprint 8100.0012.0002 (Unified Evidence Model), Sprint 8100.0012.0003 (Graph Root Attestation) — both depend on stable versioned hashing.
- **Safe to run in parallel with:** Unrelated module work.
---
## Documentation Prerequisites
- `docs/modules/attestor/README.md` (Attestor architecture)
- `docs/modules/attestor/proof-chain.md` (Proof chain design)
- Product Advisory: Merkle-Hash REG (this sprint's origin)
---
## Problem Statement
### Current State
The `ContentAddressedIdGenerator` computes hashes by:
1. Serializing predicates to JSON with `JsonSerializer`
2. Canonicalizing via `IJsonCanonicalizer` (RFC 8785)
3. Computing SHA-256 of canonical bytes
**Problem:** If the canonicalization algorithm ever changes (bug fix, spec update, optimization), existing hashes become invalid with no way to distinguish which version produced them.
### Target State
Include a version marker in the canonical representation:
```json
{
"_canonVersion": "stella:canon:v1",
"evidenceSource": "...",
"sbomEntryId": "...",
...
}
```
The version marker:
- Is sorted first (underscore prefix ensures lexicographic ordering)
- Identifies the exact canonicalization algorithm used
- Enables verifiers to select the correct algorithm
- Allows graceful migration to future versions
---
## Design Specification
### CanonVersion Constants
```csharp
// src/__Libraries/StellaOps.Canonical.Json/CanonVersion.cs
namespace StellaOps.Canonical.Json;
/// <summary>
/// Canonicalization version identifiers for content-addressed hashing.
/// </summary>
public static class CanonVersion
{
/// <summary>
/// Version 1: RFC 8785 JSON canonicalization with:
/// - Ordinal key sorting
/// - No whitespace
/// - UTF-8 encoding without BOM
/// - IEEE 754 number formatting
/// </summary>
public const string V1 = "stella:canon:v1";
/// <summary>
/// Field name for version marker in canonical JSON.
/// Underscore prefix ensures it sorts first.
/// </summary>
public const string VersionFieldName = "_canonVersion";
/// <summary>
/// Current default version for new hashes.
/// </summary>
public const string Current = V1;
}
```
### Updated CanonJson API
```csharp
// src/__Libraries/StellaOps.Canonical.Json/CanonJson.cs (additions)
/// <summary>
/// Canonicalizes an object with version marker for content-addressed hashing.
/// </summary>
/// <typeparam name="T">The type to serialize.</typeparam>
/// <param name="obj">The object to canonicalize.</param>
/// <param name="version">Canonicalization version (default: Current).</param>
/// <returns>UTF-8 encoded canonical JSON bytes with version marker.</returns>
public static byte[] CanonicalizeVersioned<T>(T obj, string version = CanonVersion.Current)
{
var json = JsonSerializer.SerializeToUtf8Bytes(obj, DefaultOptions);
using var doc = JsonDocument.Parse(json);
using var ms = new MemoryStream();
using var writer = new Utf8JsonWriter(ms, new JsonWriterOptions { Indented = false });
writer.WriteStartObject();
writer.WriteString(CanonVersion.VersionFieldName, version);
// Write sorted properties from original object
foreach (var prop in doc.RootElement.EnumerateObject()
.OrderBy(p => p.Name, StringComparer.Ordinal))
{
writer.WritePropertyName(prop.Name);
WriteElementSorted(prop.Value, writer);
}
writer.WriteEndObject();
writer.Flush();
return ms.ToArray();
}
/// <summary>
/// Computes SHA-256 hash with version marker.
/// </summary>
public static string HashVersioned<T>(T obj, string version = CanonVersion.Current)
{
var canonical = CanonicalizeVersioned(obj, version);
return Sha256Hex(canonical);
}
/// <summary>
/// Computes prefixed SHA-256 hash with version marker.
/// </summary>
public static string HashVersionedPrefixed<T>(T obj, string version = CanonVersion.Current)
{
var canonical = CanonicalizeVersioned(obj, version);
return Sha256Prefixed(canonical);
}
```
### Updated ContentAddressedIdGenerator
```csharp
// src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Identifiers/ContentAddressedIdGenerator.cs
public EvidenceId ComputeEvidenceId(EvidencePredicate predicate)
{
ArgumentNullException.ThrowIfNull(predicate);
// Clear self-referential field, add version marker
var toHash = predicate with { EvidenceId = null };
var canonical = CanonicalizeVersioned(toHash, CanonVersion.Current);
return new EvidenceId(HashSha256Hex(canonical));
}
// Similar updates for ComputeReasoningId, ComputeVexVerdictId, etc.
private byte[] CanonicalizeVersioned<T>(T value, string version)
{
var json = JsonSerializer.SerializeToUtf8Bytes(value, SerializerOptions);
return _canonicalizer.CanonicalizeWithVersion(json, version);
}
```
### IJsonCanonicalizer Extension
```csharp
// src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Json/IJsonCanonicalizer.cs
public interface IJsonCanonicalizer
{
/// <summary>
/// Canonicalizes JSON bytes per RFC 8785.
/// </summary>
byte[] Canonicalize(ReadOnlySpan<byte> json);
/// <summary>
/// Canonicalizes JSON bytes with version marker prepended.
/// </summary>
byte[] CanonicalizeWithVersion(ReadOnlySpan<byte> json, string version);
}
```
---
## Backward Compatibility Strategy
### Phase 1: Dual-Mode (This Sprint)
- **Generation:** Always emit versioned hashes (v1)
- **Verification:** Accept both legacy (unversioned) and v1 hashes
- **Detection:** Check if canonical JSON starts with `{"_canonVersion":` to determine format
```csharp
public static bool IsVersionedHash(ReadOnlySpan<byte> canonicalJson)
{
// Check for version field at start (after lexicographic sorting, _ comes first)
return canonicalJson.Length > 20 &&
canonicalJson.StartsWith("{\"_canonVersion\":"u8);
}
```
### Phase 2: Migration (Future Sprint)
- Emit migration warnings for legacy hashes in logs
- Provide tooling to rehash attestations with version marker
- Document upgrade path in `docs/operations/canon-version-migration.md`
### Phase 3: Deprecation (Future Sprint)
- Remove legacy hash acceptance
- Fail verification for unversioned hashes

## Test Cases
### TC-001: Versioned Hash Differs from Legacy
```csharp
[Fact]
public void VersionedHash_DiffersFromLegacy_ForSameInput()
{
var predicate = new EvidencePredicate { /* ... */ };
var legacyHash = CanonJson.Hash(predicate);
var versionedHash = CanonJson.HashVersioned(predicate, CanonVersion.V1);
Assert.NotEqual(legacyHash, versionedHash);
}
```
### TC-002: Determinism Across Environments
```csharp
[Fact]
public void VersionedHash_IsDeterministic()
{
var predicate = new EvidencePredicate { /* ... */ };
var hash1 = CanonJson.HashVersioned(predicate, CanonVersion.V1);
var hash2 = CanonJson.HashVersioned(predicate, CanonVersion.V1);
Assert.Equal(hash1, hash2);
}
```
### TC-003: Version Field Sorts First
```csharp
[Fact]
public void VersionedCanonical_HasVersionFieldFirst()
{
var predicate = new EvidencePredicate { Source = "test" };
var canonical = CanonJson.CanonicalizeVersioned(predicate, CanonVersion.V1);
var json = Encoding.UTF8.GetString(canonical);
Assert.StartsWith("{\"_canonVersion\":\"stella:canon:v1\"", json);
}
```
### TC-004: Golden File Stability
```csharp
[Fact]
public async Task VersionedCanonical_MatchesGoldenFile()
{
var predicate = CreateKnownPredicate();
var canonical = CanonJson.CanonicalizeVersioned(predicate, CanonVersion.V1);
await Verify(Encoding.UTF8.GetString(canonical))
.UseDirectory("Golden")
.UseFileName("EvidencePredicate_v1");
}
```
---
## Decisions & Risks
### Decisions
| Decision | Rationale |
|----------|-----------|
| Use underscore prefix for version field | Ensures lexicographic first position |
| Version string format `stella:canon:v1` | Namespaced, unambiguous, extensible |
| Dual-mode verification initially | Backward compatibility for existing attestations |
| Version field in payload, not hash prefix | Keeps hash format consistent (sha256:...) |
### Risks
| Risk | Impact | Mitigation | Owner |
|------|--------|------------|-------|
| Existing attestations invalidated | Verification failures | Dual-mode verification; migration tooling | Attestor Guild |
| Performance overhead of version injection | Latency | Minimal (~100 bytes); benchmark | Platform Guild |
| Version field conflicts with user data | Hash collision | Reserved `_` prefix; schema validation | Attestor Guild |

| GROOT-8100-010 | No dedicated Rekor client library exists. GraphRootAttestor line 129 states "Rekor publishing would be handled by a separate service". | Architect/PM to decide: (a) create IRekorClient library, or (b) defer Rekor to future sprint, or (c) mark optional and skip. |

### Blockers (Policy Engine Integration - Tasks 35-40)
The following architectural issues block Wave 5:
1. **Internal class visibility**: `PolicyEvaluator` in `StellaOps.Policy.Engine` is `internal sealed`. Injecting `IProvcacheService` requires either:
- Making it public with a DI-friendly constructor pattern
- Creating a wrapper service layer that orchestrates caching + evaluation
- Adding a caching layer at a higher level (e.g., at the API/orchestration layer)
2. **Integration point unclear**: The Policy Engine has multiple evaluation entry points:
- `PolicyEvaluator.Evaluate()` - internal, per-finding evaluation
- `EvaluationOrchestrationWorker` - batch evaluation orchestrator
- `PolicyRuntimeEvaluationService` - used by tests
- Needs architectural decision on which layer owns the cache read/write responsibility
3. **VeriKey construction from context**: `PolicyEvaluationContext` contains many inputs, but mapping them to `VeriKeyBuilder` inputs requires:
- Defining canonical serialization for SBOM, VEX statements, advisory metadata
- Ensuring all inputs that affect the decision are included in the VeriKey
- Excluding non-deterministic fields (timestamps, request IDs)
**Recommendation**: Create a separate sprint for Policy Engine integration after architectural review with Policy Guild. The Provcache core library is complete and can be used independently.

| 2025-01-20 | Wave 0 complete: package reference exists, PolicyEvidenceWeightedScoreOptions created with feature flags (Enabled, DualEmitMode, UseAsPrimaryScore, EnableCaching, Weights, BucketThresholds). | Implementer |
| 2025-01-20 | Wave 1 Tasks 3,4,7 complete: Created IFindingScoreEnricher interface (IFindingScoreEnricher, ScoreEnrichmentResult, IScoreEnrichmentCache, NullFindingScoreEnricher), EvidenceWeightedScoreEnricher implementation, PolicyEvaluationContextEwsExtensions (evidence extraction from PolicyEvaluationContext), InMemoryScoreEnrichmentCache with telemetry. | Implementer |
| 2025-01-20 | Wave 1 Tasks 5,6 remaining: Enricher not yet injected into PolicyEvaluator pipeline; score result not yet added to PolicyEvaluationContext as consumable field. These require modifying internal classes PolicyEvaluator and PolicyEvaluationContext. | Implementer |
| 2025-01-20 | Wave 1 Task 8 BLOCKED: Test file created (EvidenceWeightedScoreEnricherTests.cs, ~20 tests) but cannot run due to pre-existing compilation errors in Policy.Engine.Tests project (VexClaimStatus.Unknown does not exist, DeltaMagnitude members missing, ILogger import missing). Need separate fix sprint. | Implementer |
| 2025-01-20 | Fixed pre-existing issues: Removed duplicate ConnectorSecurityTestBase from ConnectorResilienceTestBase.cs; Added Microsoft.Extensions.Logging import to VexLatticeMergePropertyTests.cs; Fixed PolicyEngineDeterminismTests.cs import. | Implementer |
| 2025-01-20 | Core EWS library (Signals) confirmed working: 1196 tests pass. Policy.Engine.dll compiles successfully with all Wave 0-1 code. | Implementer |
| 2025-12-24 | Wave 1 Tasks 5,6 COMPLETE: Integrated IFindingScoreEnricher into PolicyEvaluator constructor; Added ApplyEvidenceWeightedScore() method that runs after ApplyConfidence(); Added EvidenceWeightedScoreResult? field to PolicyEvaluationResult record; Enricher extracts evidence using PolicyEvaluationContextEwsExtensions and populates EWS annotations (ews.score, ews.bucket). Policy.Engine.dll compiles successfully. | Implementer || 2025-12-24 | Wave 2 Tasks 9-13 COMPLETE: Refactored PolicyEvaluator to pre-compute EWS BEFORE rule evaluation via PrecomputeEvidenceWeightedScore(); Added ScoreScope class to PolicyExpressionEvaluator; Score is accessible via "score" identifier; Added "score" case to ResolveIdentifier and EvaluateMember; ScoreScope provides: value, bucket, is_act_now/schedule_next/investigate/watchlist, rch/rts/bkp/xpl/src/mit dimensions, flags, has_flag(), between() methods. All standard comparison operators work on score.value. | Implementer |
| 2025-12-24 | Wave 3 Tasks 16-18 COMPLETE (implicit): DSL grammar extension is achieved via ScoreScope in the existing expression evaluator. The existing PolicyExpressionEvaluator already supports member access (score.bucket), method calls (score.has_flag("x")), and comparisons (score >= 80). No additional parser changes needed. Task 19 (autocomplete hints) remains TODO. | Implementer |
| 2025-12-24 | Wave 4 Tasks 22-23 COMPLETE (implicit): EvidenceWeightedScoreResult? field already added to PolicyEvaluationResult in Wave 1. ApplyEvidenceWeightedScore populates it from precomputed or freshly calculated score. | Implementer |
| 2025-12-31 | Task 19 (PINT-8200-019) COMPLETE: Added DSL autocomplete hints for score fields. Created DslCompletionProvider.cs in StellaOps.PolicyDsl with: DslCompletionCatalog (singleton with all completions by category), GetCompletionsForContext (context-aware completion filtering), score fields (value, bucket, is_act_now, flags, rch, rts, bkp, xpl, src, mit + aliases), score buckets (ActNow, ScheduleNext, Investigate, Watchlist), score flags (kev, live-signal, vendor-na, etc.). Also updated stella-dsl.completions.ts in frontend (Monaco editor) with score namespace completions and context detection for score.bucket and score.flags. Added unit tests in DslCompletionProviderTests.cs (~30 tests). | Implementer |
| 2025-12-31 | Task 24 (PINT-8200-024) COMPLETE: Created VerdictSummary.cs with: VerdictSummary record (status, severity, bucket, score, top 5 factors, flags, explanations, guardrails, warnings, exception, confidence), VerdictFactor record (dimension, symbol, contribution, weight, input value, subtractive flag), VerdictSummaryExtensions (ToSummary, ToMinimalSummary, GetPrimaryFactor, FormatTriageLine, GetBucketExplanation). Extension methods are internal since PolicyEvaluationResult is internal. Added unit tests in VerdictSummaryTests.cs (~30 tests). Policy.Engine.dll compiles successfully. | Implementer |
| 2025-12-31 | Task 25 (PINT-8200-025) COMPLETE: Created VerdictEvidenceWeightedScore.cs with: VerdictEvidenceWeightedScore, VerdictDimensionContribution, VerdictAppliedGuardrails records for serialization. Added EvidenceWeightedScore? field to PolicyExplainTrace. Updated VerdictPredicate to include EvidenceWeightedScore property. Updated VerdictPredicateBuilder to populate EWS from trace. Full EWS decomposition (score, bucket, breakdown, flags, explanations, policy digest, guardrails) now included in verdict JSON. | Implementer |
| 2025-12-31 | Tasks 27,28 (PINT-8200-027, PINT-8200-028) COMPLETE: Task 27 completed implicitly via Task 25 (EWS now in VerdictPredicate). Task 28: Added VerdictScoringProof record with inputs (VerdictEvidenceInputs), weights (VerdictEvidenceWeights), policy digest, calculator version, and timestamp. Proof enables deterministic recalculation for verification. VerdictEvidenceWeightedScore.Proof property contains full scoring proof. | Implementer |

# Sprint 5100.0007.0001 · Testing Strategy Models & Lanes
## Topic & Scope
- Establish a repo-wide testing model taxonomy and catalog that standardizes required test types per project.
- Align CI lanes and documentation with the model taxonomy to keep determinism and offline guarantees enforceable.
- **Working directory:** `docs/testing`.
- **Evidence:** `docs/testing/testing-strategy-models.md`, `docs/testing/TEST_CATALOG.yml`, `docs/benchmarks/testing/better-testing-strategy-samples.md`, plus updated links in `docs/19_TEST_SUITE_OVERVIEW.md`, `docs/07_HIGH_LEVEL_ARCHITECTURE.md`, `docs/key-features.md`, `docs/modules/platform/architecture-overview.md`, and `docs/modules/ci/architecture.md`.
## Dependencies & Concurrency
- Builds on archived testing strategy guidance: `docs/product-advisories/archived/2025-12-21-testing-strategy/20-Dec-2025 - Testing strategy.md`.
- Complements Testing Quality Guardrails sprints (0350-0353); no direct code overlap expected.
- Safe to run in parallel with UI sprints (4000 series) and module-specific delivery as long as CI lane names remain stable.
## Documentation Prerequisites
- `docs/product-advisories/22-Dec-2026 - Better testing strategy.md`
- `docs/19_TEST_SUITE_OVERVIEW.md`
- `docs/testing/testing-quality-guardrails-implementation.md`
- `docs/modules/platform/architecture-overview.md`
- `docs/modules/ci/architecture.md`

## Wave Coordination
- **Wave 1 (Docs + Catalog):** Tasks 1-3 — COMPLETE.
- **Wave 2 (Quick Wins - Week 1 Priorities):** Tasks 4-7 — High-impact, low-friction wins from advisory Section 7.
- **Wave 3 (CI Infrastructure):** Tasks 8-10 — Root test scripts, trait standardization, CI workflow updates.
- **Wave 4 (Follow-up Epic Sprints):** Tasks 11-18 — Create detailed implementation sprints for Epics A-F, Competitor Parity, and module-specific work.
## Wave Detail Snapshots
- **Wave 1 evidence:** Strategy doc, test catalog, benchmark samples, and updated cross-links (DONE).
- **Wave 2 evidence:** Property tests added, Pact contract test, flaky E2E tests converted, OTel assertions in integration suite.
- **Wave 3 evidence:** Test runner scripts in `build/`, trait standardization PR, CI workflow updates.
- **Wave 4 evidence:** New sprint files created under `docs/implplan/` for each epic and module.
## Interlocks
- CI lane updates require coordination with `docs/modules/ci/AGENTS.md` and CI workflow owners.
- TestKit delivery requires `src/__Libraries` architecture review and module AGENTS alignment.
- Module-specific test gaps must be tracked in their own sprint files under `docs/implplan/`.
## Upcoming Checkpoints
- 2025-12-30: Docs + catalog review (Docs Guild).
- 2026-01-15: CI lane filter alignment plan (CI Guild).
## Action Tracker
| Date (UTC) | Action | Owner |
| --- | --- | --- |
| 2025-12-30 | Confirm lane category names with CI workflow owners. | CI Guild |
| 2026-01-15 | Draft TestKit architecture stub for review. | Platform Guild |
## Decisions & Risks
- **Decision:** Adopt a model-driven testing taxonomy and treat `docs/testing/TEST_CATALOG.yml` as the source of truth for required test types and module coverage.
- **Decision:** Maintain lane filters as Unit, Contract, Integration, Security, Performance, Live (opt-in only).
- **Decision:** Keep offline/determinism defaults mandatory for all non-Live lanes.
- **Docs updated:** `docs/testing/testing-strategy-models.md`, `docs/testing/TEST_CATALOG.yml`, `docs/benchmarks/testing/better-testing-strategy-samples.md`, `docs/19_TEST_SUITE_OVERVIEW.md`, `docs/07_HIGH_LEVEL_ARCHITECTURE.md`, `docs/key-features.md`, `docs/modules/platform/architecture-overview.md`, `docs/modules/ci/architecture.md`.
| Risk | Impact | Mitigation | Owner |
| --- | --- | --- | --- |
| Lane name drift across workflows | CI filters mis-route tests | Pin category names in Test Catalog and update workflows together. | CI Guild |
| TestKit scope creep | Delays adoption | Keep v1 to deterministic time/random + canonical JSON + fixtures. | Platform Guild |
| Live connector tests gated in PRs | Unstable CI | Keep `Live` opt-in only; schedule nightly/weekly runs. | QA Guild |

# Budget Threshold Attestation
This document describes how unknown budget thresholds are attested in verdict bundles for reproducibility and audit purposes.
## Overview
Budget attestation captures the budget configuration applied during policy evaluation, enabling:
- **Auditability**: Verify what thresholds were enforced at decision time
- **Reproducibility**: Include all inputs for deterministic verification
- **Compliance**: Demonstrate policy enforcement for regulatory requirements
## Budget Check Predicate
The budget check is included in the verdict predicate:
```json
{
"_type": "https://stellaops.dev/predicates/policy-verdict@v1",
"tenantId": "tenant-1",
"policyId": "default-policy",
"policyVersion": 1,
"verdict": { ... },
"budgetCheck": {
"environment": "production",
"config": {
"maxUnknownCount": 10,
"maxCumulativeUncertainty": 2.5,
"action": "warn",
"reasonLimits": {
"Reachability": 5,
"Identity": 3
}
},
"actualCounts": {
"total": 3,
"cumulativeUncertainty": 1.2,
"byReason": {
"Reachability": 2,
"Identity": 1
}
},
"result": "pass",
"configHash": "sha256:abc123...",
"evaluatedAt": "2025-12-25T12:00:00Z",
"violations": []
}
}
```
## Fields
### budgetCheck.config
| Field | Type | Description |
|-------|------|-------------|
| `maxUnknownCount` | int | Maximum total unknowns allowed |
| `maxCumulativeUncertainty` | double | Maximum uncertainty score |
| `action` | string | Action when exceeded: warn, block |
| `reasonLimits` | object | Per-reason code limits |
### budgetCheck.actualCounts
| Field | Type | Description |
|-------|------|-------------|
| `total` | int | Total unknowns observed |
| `cumulativeUncertainty` | double | Sum of uncertainty factors |
| `byReason` | object | Breakdown by reason code |
### budgetCheck.result
Possible values:
- `pass` - All limits satisfied
- `warn` - Limits exceeded but action is warn
- `fail` - Limits exceeded and action is block
### budgetCheck.configHash
SHA-256 hash of the budget configuration for determinism verification. Format: `sha256:{64 hex characters}`
### budgetCheck.violations
List of violations when limits are exceeded:
```json
{
"violations": [
{
"type": "total",
"limit": 10,
"actual": 15
},
{
"type": "reason",
"limit": 5,
"actual": 8,
"reason": "Reachability"
}
]
}
```
## Usage
### Extracting Budget Check from Verdict
```csharp
using StellaOps.Policy.Engine.Attestation;
// Parse verdict predicate from DSSE envelope
var predicate = VerdictPredicate.Parse(dssePayload);
// Access budget check
if (predicate.BudgetCheck is not null)
{
var check = predicate.BudgetCheck;
Console.WriteLine($"Environment: {check.Environment}");
Console.WriteLine($"Result: {check.Result}");
Console.WriteLine($"Total: {check.ActualCounts.Total}/{check.Config.MaxUnknownCount}");
Console.WriteLine($"Config Hash: {check.ConfigHash}");
}
```
### Verifying Configuration Hash
```csharp
// Compute expected hash from current configuration
var currentConfig = new VerdictBudgetConfig(
maxUnknownCount: 10,
maxCumulativeUncertainty: 2.5,
action: "warn");
var expectedHash = VerdictBudgetCheck.ComputeConfigHash(currentConfig);
// Compare with attested hash
if (predicate.BudgetCheck?.ConfigHash != expectedHash)
{
Console.WriteLine("Warning: Budget configuration has changed since attestation");
}
```
## Determinism
The config hash ensures reproducibility:
1. Configuration is serialized to JSON with canonical ordering
2. SHA-256 is computed over the UTF-8 bytes
3. Hash is prefixed with `sha256:` algorithm identifier
This allows verification that the same budget configuration was used across runs.
## Integration Points
### VerdictPredicateBuilder
Budget check is added when building verdict predicates:
```csharp
var budgetCheck = new VerdictBudgetCheck(
environment: context.Environment,

### UnknownBudgetService
The enhanced `BudgetCheckResult` includes all data needed for attestation:
```csharp
var result = await budgetService.CheckBudget(environment, unknowns);
// result.Budget - the configuration applied
// result.CountsByReason - breakdown for attestation
// result.CumulativeUncertainty - total uncertainty score
```
