+### 8) Code Quality & Determinism Rules
+
+These rules were distilled from a comprehensive audit of 324+ projects. They address the most common recurring issues and must be followed by all implementers.
+
+#### 8.1) Compiler & Warning Discipline
+
+| Rule | Guidance |
+|------|----------|
+| **Enable TreatWarningsAsErrors** | All projects must set `<TreatWarningsAsErrors>true</TreatWarningsAsErrors>` in the `.csproj` or via `Directory.Build.props`. Relaxed warnings mask regressions and code quality drift. |
+
+```xml
+<!-- In .csproj or Directory.Build.props -->
+<PropertyGroup>
+  <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
+</PropertyGroup>
+```
+
+#### 8.2) Deterministic Time & ID Generation
+
+| Rule | Guidance |
+|------|----------|
+| **Inject TimeProvider / ID generators** | Never use `DateTime.UtcNow`, `DateTimeOffset.UtcNow`, `Guid.NewGuid()`, or `Random.Shared` directly in production code. Inject `TimeProvider` (or `ITimeProvider`) and `IGuidGenerator` abstractions. |
+
+```csharp
+// BAD - nondeterministic, hard to test
+public class BadService
+{
+    public Record CreateRecord() => new Record
+    {
+        Id = Guid.NewGuid(),
+        CreatedAt = DateTimeOffset.UtcNow
+    };
+}
+
+// GOOD - injectable, testable, deterministic
+public class GoodService(TimeProvider timeProvider, IGuidGenerator guidGenerator)
+{
+    public Record CreateRecord() => new Record
+    {
+        Id = guidGenerator.NewGuid(),
+        CreatedAt = timeProvider.GetUtcNow()
+    };
+}
+```
+
+#### 8.3) ASCII-Only Output
+
+| Rule | Guidance |
+|------|----------|
+| **No mojibake or non-ASCII glyphs** | Use ASCII-only characters in comments, output strings, and log messages. No `ƒ?`, `バ`, `→`, `✓`, `✗`, or box-drawing characters. When Unicode is truly required, use explicit escapes (`\uXXXX`) and document the rationale. |
+
+```csharp
+// BAD - non-ASCII glyphs
+Console.WriteLine("✓ Success → proceeding");
+// or mojibake comments like: // ƒ+ validation passed
+
+// GOOD - ASCII only
+Console.WriteLine("[OK] Success - proceeding");
+// Comment: validation passed
+```
+
+#### 8.4) Test Project Requirements
+
+| Rule | Guidance |
+|------|----------|
+| **Every library needs tests** | All production libraries/services must have a corresponding `*.Tests` project covering: (a) happy paths, (b) error/edge cases, (c) determinism, and (d) serialization round-trips. |
+
+```
+src/
+  Scanner/
+    __Libraries/
+      StellaOps.Scanner.Core/
+    __Tests/
+      StellaOps.Scanner.Core.Tests/   <-- Required
+```
+
+#### 8.5) Culture-Invariant Parsing
+
+| Rule | Guidance |
+|------|----------|
+| **Use InvariantCulture** | Always use `CultureInfo.InvariantCulture` for parsing and formatting dates, numbers, percentages, and any string that will be persisted, hashed, or compared. Current culture causes locale-dependent, nondeterministic behavior. |
+
+```csharp
+// BAD - culture-sensitive
+var value = double.Parse(input);
+var formatted = percentage.ToString("P2");
+
+// GOOD - invariant culture
+var value = double.Parse(input, CultureInfo.InvariantCulture);
+var formatted = percentage.ToString("P2", CultureInfo.InvariantCulture);
+```
+
+#### 8.6) DSSE PAE Consistency
+
+| Rule | Guidance |
+|------|----------|
+| **Single DSSE PAE implementation** | Use one spec-compliant DSSE PAE helper (`StellaOps.Attestation.DsseHelper` or equivalent) across the codebase. DSSE v1 requires ASCII decimal lengths and space separators. Never reimplement PAE encoding. |
+
+```csharp
+// BAD - custom PAE implementation
+var pae = $"DSSEv1 {payloadType.Length} {payloadType} {payload.Length} ";
+
+// GOOD - use shared helper
+var pae = DsseHelper.ComputePreAuthenticationEncoding(payloadType, payload);
+```
+
+#### 8.7) RFC 8785 JSON Canonicalization
+
+| Rule | Guidance |
+|------|----------|
+| **Use shared RFC 8785 canonicalizer** | For digest/signature inputs, use a shared RFC 8785-compliant JSON canonicalizer with: sorted keys, minimal escaping per spec, no exponent notation for numbers, no trailing/leading zeros. Do not use `UnsafeRelaxedJsonEscaping` or `CamelCase` naming for canonical outputs. |
+
+```csharp
+// BAD - non-canonical JSON
+var json = JsonSerializer.Serialize(obj, new JsonSerializerOptions
+{
+    Encoder = JavaScriptEncoder.UnsafeRelaxedJsonEscaping,
+    PropertyNamingPolicy = JsonNamingPolicy.CamelCase
+});
+
+// GOOD - use shared canonicalizer
+var canonicalJson = CanonicalJsonSerializer.Serialize(obj);
+var digest = ComputeDigest(canonicalJson);
+```
+
+#### 8.8) CancellationToken Propagation
+
+| Rule | Guidance |
+|------|----------|
+| **Propagate CancellationToken** | Always propagate `CancellationToken` through async call chains. Never use `CancellationToken.None` in production code except at entry points where no token is available. |
+
+```csharp
+// BAD - ignores cancellation
+public async Task ProcessAsync(CancellationToken ct)
+{
+    await _repository.SaveAsync(data, CancellationToken.None);  // Wrong!
+    await Task.Delay(1000);  // Missing ct
+}
+
+// GOOD - propagates cancellation
+public async Task ProcessAsync(CancellationToken ct)
+{
+    await _repository.SaveAsync(data, ct);
+    await Task.Delay(1000, ct);
+}
+```
+
+#### 8.9) HttpClient via Factory
+
+| Rule | Guidance |
+|------|----------|
+| **Use IHttpClientFactory** | Never `new HttpClient()` directly. Use `IHttpClientFactory` with configured timeouts and retry policies via Polly or `Microsoft.Extensions.Http.Resilience`. Direct HttpClient creation risks socket exhaustion. |
+
+```csharp
+// BAD - direct instantiation
+public class BadService
+{
+    public async Task FetchAsync()
+    {
+        using var client = new HttpClient();  // Socket exhaustion risk
+        await client.GetAsync(url);
+    }
+}
+
+// GOOD - factory with resilience
+public class GoodService(IHttpClientFactory httpClientFactory)
+{
+    public async Task FetchAsync()
+    {
+        var client = httpClientFactory.CreateClient("MyApi");
+        await client.GetAsync(url);
+    }
+}
+
+// Registration with timeout/retry
+services.AddHttpClient("MyApi")
+    .ConfigureHttpClient(c => c.Timeout = TimeSpan.FromSeconds(30))
+    .AddStandardResilienceHandler();
+```
+
+#### 8.10) Path/Root Resolution
+
+| Rule | Guidance |
+|------|----------|
+| **Explicit CLI options for paths** | Do not derive repository root from `AppContext.BaseDirectory` with parent directory walks. Use explicit CLI options (`--repo-root`) or environment variables. Provide sensible defaults with clear error messages. |
+
+```csharp
+// BAD - fragile parent walks
+var repoRoot = Path.GetFullPath(Path.Combine(
+    AppContext.BaseDirectory, "..", "..", "..", ".."));
+
+// GOOD - explicit option with fallback
+[Option("--repo-root", Description = "Repository root path")]
+public string? RepoRoot { get; set; }
+
+public string GetRepoRoot() =>
+    RepoRoot ?? Environment.GetEnvironmentVariable("STELLAOPS_REPO_ROOT")
+    ?? throw new InvalidOperationException("Repository root not specified. Use --repo-root or set STELLAOPS_REPO_ROOT.");
+```
+
+#### 8.11) Test Categorization
+
+| Rule | Guidance |
+|------|----------|
+| **Correct test categories** | Tag tests correctly: `[Trait("Category", "Unit")]` for pure unit tests, `[Trait("Category", "Integration")]` for tests requiring databases, containers, or network. Don't mix DB/network tests into unit suites. |
+
+```csharp
+// BAD - integration test marked as unit
+public class UserRepositoryTests  // Uses Testcontainers/Postgres
+{
+    [Fact]  // Missing category, runs with unit tests
+    public async Task Save_PersistsUser() { ... }
+}
+
+// GOOD - correctly categorized
+[Trait("Category", "Integration")]
+public class UserRepositoryTests
+{
+    [Fact]
+    public async Task Save_PersistsUser() { ... }
+}
+
+[Trait("Category", "Unit")]
+public class UserValidatorTests
+{
+    [Fact]
+    public void Validate_EmptyEmail_ReturnsFalse() { ... }
+}
+```
+
+#### 8.12) No Silent Stubs
+
+| Rule | Guidance |
+|------|----------|
+| **Unimplemented code must throw** | Placeholder code must throw `NotImplementedException` or return an explicit error/unsupported status. Never return success (`null`, empty results, or success codes) from unimplemented paths. |
+
+```csharp
+// BAD - silent stub masks missing implementation
+public async Task<Result> ProcessAsync()
+{
+    // TODO: implement later
+    return Result.Success();  // Ships broken feature!
+}
+
+// GOOD - explicit failure
+public async Task<Result> ProcessAsync()
+{
+    throw new NotImplementedException("ProcessAsync not yet implemented. See SPRINT_XYZ.");
+}
+```
+
+#### 8.13) Immutable Collection Returns
+
+| Rule | Guidance |
+|------|----------|
+| **Return immutable collections** | Public APIs must return `IReadOnlyList<T>`, `ImmutableArray<T>`, or defensive copies. Never expose mutable backing stores that callers can mutate. |
+
+```csharp
+// BAD - exposes mutable backing store
+public class BadRegistry
+{
+    private readonly List<string> _scopes = new();
+    public List<string> Scopes => _scopes;  // Callers can mutate!
+}
+
+// GOOD - immutable return
+public class GoodRegistry
+{
+    private readonly List<string> _scopes = new();
+    public IReadOnlyList<string> Scopes => _scopes.AsReadOnly();
+    // or: public ImmutableArray<string> Scopes => _scopes.ToImmutableArray();
+}
+```
+
+#### 8.14) Options Validation at Startup
+
+| Rule | Guidance |
+|------|----------|
+| **ValidateOnStart for options** | Use `ValidateDataAnnotations()` and `ValidateOnStart()` for options. Implement `IValidateOptions<T>` for complex validation. All required config must be validated at startup, not at first use. |
+
+```csharp
+// BAD - no validation until runtime failure
+services.Configure<MyOptions>(config.GetSection("My"));
+
+// GOOD - validated at startup
+services.AddOptions<MyOptions>()
+    .Bind(config.GetSection("My"))
+    .ValidateDataAnnotations()
+    .ValidateOnStart();
+
+// With complex validation
+public class MyOptionsValidator : IValidateOptions<MyOptions>
+{
+    public ValidateOptionsResult Validate(string? name, MyOptions options)
+    {
+        if (options.Timeout <= TimeSpan.Zero)
+            return ValidateOptionsResult.Fail("Timeout must be positive");
+        return ValidateOptionsResult.Success;
+    }
+}
+```
+
+#### 8.15) No Backup Files in Source
+
+| Rule | Guidance |
+|------|----------|
+| **Exclude backup/temp artifacts** | Add backup patterns (`*.Backup.tmp`, `*.bak`, `*.orig`) to `.gitignore`. Regularly audit for and remove stray artifacts. Consolidate duplicate tools/harnesses. |
+
+```gitignore
+# .gitignore additions
+*.Backup.tmp
+*.bak
+*.orig
+*~
+```
+
+#### 8.16) Test Production Code, Not Reimplementations
+
+| Rule | Guidance |
+|------|----------|
+| **Helpers call production code** | Test helpers must call production code, not reimplement algorithms (Merkle trees, DSSE PAE, parsers, canonicalizers). Only mock I/O and network boundaries. Reimplementations cause test/production drift. |
+
+```csharp
+// BAD - test reimplements production logic
+[Fact]
+public void Merkle_ComputesCorrectRoot()
+{
+    // Custom Merkle implementation in test
+    var root = TestMerkleHelper.ComputeRoot(leaves);  // Drift risk!
+    Assert.Equal(expected, root);
+}
+
+// GOOD - test exercises production code
+[Fact]
+public void Merkle_ComputesCorrectRoot()
+{
+    // Uses production MerkleTreeBuilder
+    var root = MerkleTreeBuilder.ComputeRoot(leaves);
+    Assert.Equal(expected, root);
+}
+```
+
+#### 8.17) Bounded Caches with Eviction
+
+| Rule | Guidance |
+|------|----------|
+| **No unbounded Dictionary caches** | Do not use `ConcurrentDictionary` or `Dictionary` for caching without eviction policies. Use bounded caches with TTL/LRU eviction (`MemoryCache` with size limits, or external cache like Valkey). Document expected cardinality and eviction behavior. |
+
+```csharp
+// BAD - unbounded growth
+private readonly ConcurrentDictionary<string, CacheEntry> _cache = new();
+
+public void Add(string key, CacheEntry entry)
+{
+    _cache[key] = entry;  // Never evicts, memory grows forever
+}
+
+// GOOD - bounded with eviction
+private readonly MemoryCache _cache = new(new MemoryCacheOptions
+{
+    SizeLimit = 10_000
+});
+
+public void Add(string key, CacheEntry entry)
+{
+    _cache.Set(key, entry, new MemoryCacheEntryOptions
+    {
+        Size = 1,
+        SlidingExpiration = TimeSpan.FromMinutes(30)
+    });
+}
+```
+
+#### 8.18) DateTimeOffset for PostgreSQL timestamptz
+
+| Rule | Guidance |
+|------|----------|
+| **Use GetFieldValue&lt;DateTimeOffset&gt;** | PostgreSQL `timestamptz` columns must be read via `reader.GetFieldValue<DateTimeOffset>()`, not `reader.GetDateTime()`. `GetDateTime()` loses offset information and causes UTC/local confusion. Store and retrieve all timestamps as UTC `DateTimeOffset`. |
+
+```csharp
+// BAD - loses offset information
+var createdAt = reader.GetDateTime(reader.GetOrdinal("created_at"));
+
+// GOOD - preserves offset
+var createdAt = reader.GetFieldValue<DateTimeOffset>(reader.GetOrdinal("created_at"));
+```

+### 8.15) No Backup Files in Source
+
+| Rule | Guidance |
+|------|----------|
+| **Exclude backup/temp artifacts** | Add backup patterns (`*.Backup.tmp`, `*.bak`, `*.orig`) to `.gitignore`. Regularly audit for and remove stray artifacts. Consolidate duplicate tools/harnesses. |
+
+```gitignore
+# .gitignore additions
+*.Backup.tmp
+*.bak
+*.orig
+*~
+```
+
+### 8.16) Test Production Code, Not Reimplementations
+
+| Rule | Guidance |
+|------|----------|
+| **Helpers call production code** | Test helpers must call production code, not reimplement algorithms (Merkle trees, DSSE PAE, parsers, canonicalizers). Only mock I/O and network boundaries. Reimplementations cause test/production drift. |
+
+```csharp
+// BAD - test reimplements production logic
+[Fact]
+public void Merkle_ComputesCorrectRoot()
+{
+    // Custom Merkle implementation in test
+    var root = TestMerkleHelper.ComputeRoot(leaves);  // Drift risk!
+    Assert.Equal(expected, root);
+}
+
+// GOOD - test exercises production code
+[Fact]
+public void Merkle_ComputesCorrectRoot()
+{
+    // Uses production MerkleTreeBuilder
+    var root = MerkleTreeBuilder.ComputeRoot(leaves);
+    Assert.Equal(expected, root);
+}
+```
+
+### 8.17) Bounded Caches with Eviction
+
+| Rule | Guidance |
+|------|----------|
+| **No unbounded Dictionary caches** | Do not use `ConcurrentDictionary` or `Dictionary` for caching without eviction policies. Use bounded caches with TTL/LRU eviction (`MemoryCache` with size limits, or external cache like Valkey). Document expected cardinality and eviction behavior. |
+
+```csharp
+// BAD - unbounded growth
+private readonly ConcurrentDictionary<string, CacheEntry> _cache = new();
+
+public void Add(string key, CacheEntry entry)
+{
+    _cache[key] = entry;  // Never evicts, memory grows forever
+}
+
+// GOOD - bounded with eviction
+private readonly MemoryCache _cache = new(new MemoryCacheOptions
+{
+    SizeLimit = 10_000
+});
+
+public void Add(string key, CacheEntry entry)
+{
+    _cache.Set(key, entry, new MemoryCacheEntryOptions
+    {
+        Size = 1,
+        SlidingExpiration = TimeSpan.FromMinutes(30)
+    });
+}
+```
+
+### 8.18) DateTimeOffset for PostgreSQL timestamptz
+
+| Rule | Guidance |
+|------|----------|
+| **Use GetFieldValue&lt;DateTimeOffset&gt;** | PostgreSQL `timestamptz` columns must be read via `reader.GetFieldValue<DateTimeOffset>()`, not `reader.GetDateTime()`. `GetDateTime()` loses offset information and causes UTC/local confusion. Store and retrieve all timestamps as UTC `DateTimeOffset`. |
+
+```csharp
+// BAD - loses offset information
+var createdAt = reader.GetDateTime(reader.GetOrdinal("created_at"));
+
+// GOOD - preserves offset
+var createdAt = reader.GetFieldValue<DateTimeOffset>(reader.GetOrdinal("created_at"));
+```

 - Decision: APPLY tasks only proceed after audit report review and explicit approval.
+- Note: Authority service Program.cs decomposition deferred for a dedicated refactor task; audit remediation focused on determinism, replay tracking, and test coverage.

+- MAINT: TreatWarningsAsErrors is set to false in the project file; warning discipline is relaxed.
+- MAINT: VexDelta defaults to Guid.NewGuid and DateTimeOffset.UtcNow (`src/Excititor/__Libraries/StellaOps.Excititor.Persistence/Repositories/IVexDeltaRepository.cs`), making IDs/timestamps nondeterministic; require explicit values or inject providers.
+- MAINT: PostgresConnectorStateRepository.SaveAsync falls back to DateTimeOffset.UtcNow when LastUpdated is missing (`src/Excititor/__Libraries/StellaOps.Excititor.Persistence/Postgres/Repositories/PostgresConnectorStateRepository.cs`); prefer explicit timestamps or a TimeProvider for deterministic persistence.

+- TEST: Parity test uses placeholder findings parsing (always empty) and therefore does not validate parity in practice. `src/__Tests/interop/StellaOps.Interop.Tests/InteropTestHarness.cs`, `src/__Tests/interop/StellaOps.Interop.Tests/CycloneDx/CycloneDxRoundTripTests.cs`
+- TEST: Schema validation tests only check string presence; TODOs remain for real SPDX/CycloneDX schema validation and consumer compatibility. `src/__Tests/interop/StellaOps.Interop.Tests/CycloneDx/CycloneDxRoundTripTests.cs`, `src/__Tests/interop/StellaOps.Interop.Tests/Spdx/SpdxRoundTripTests.cs`
+- Proposed changes (optional): add test SDK and xUnit packages; reference the production interop library; add explicit skips for missing tools and offline mode; implement Grype parsing and parity assertions; replace TODOs with real schema validation using local schema files.
+- Disposition: waived (test project; no apply changes).
+### src/__Libraries/StellaOps.IssuerDirectory.Client/StellaOps.IssuerDirectory.Client.csproj
+- MAINT: TreatWarningsAsErrors is disabled, reducing warning discipline in a shared client library. `src/__Libraries/StellaOps.IssuerDirectory.Client/StellaOps.IssuerDirectory.Client.csproj`
+- MAINT: GetIssuer* trims tenant/issuer, but Set/Delete do not trim issuerId; this can send whitespace and fail cache invalidation for trimmed keys. `src/__Libraries/StellaOps.IssuerDirectory.Client/IssuerDirectoryClient.cs`
+- MAINT: CacheKey concatenates raw segments with `|` without escaping; tenant/issuer values containing `|` can collide. `src/__Libraries/StellaOps.IssuerDirectory.Client/IssuerDirectoryClient.cs`
+- MAINT: Cache TTL options are not validated (zero/negative values accepted) and validation failures are swallowed without context in options registration. `src/__Libraries/StellaOps.IssuerDirectory.Client/IssuerDirectoryClientOptions.cs`, `src/__Libraries/StellaOps.IssuerDirectory.Client/ServiceCollectionExtensions.cs`
+- TEST: No unit tests for options validation, header injection, cache behavior, or HTTP failure handling.
+- Proposed changes (pending approval): enable TreatWarningsAsErrors; normalize issuerId in Set/Delete; escape cache key segments; validate cache TTLs and surface validation errors; add unit tests with stubbed HttpMessageHandler and MemoryCache.
+- Disposition: pending implementation (non-test project; apply recommendations remain open).
+### src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core/StellaOps.IssuerDirectory.Core.csproj
+- MAINT: TreatWarningsAsErrors is disabled, reducing warning discipline in a core library. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core/StellaOps.IssuerDirectory.Core.csproj`
+- MAINT: CreateAsync uses repository Upsert without an existence check; “create” can overwrite existing issuers without a clear conflict path. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core/Services/IssuerDirectoryService.cs`
+- MAINT: Key IDs are generated with Guid.NewGuid in service methods; tests and replay tooling cannot pin deterministic IDs without additional indirection. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core/Services/IssuerKeyService.cs`
+- MAINT: Seed refresh updates existing system seeds without writing audit entries or metrics, which can violate auditability expectations. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core/Services/IssuerDirectoryService.cs`
+- TEST: No unit tests in this project; coverage depends on Core.Tests (not assessed here) for validator, service, and audit behaviors.
+- Proposed changes (pending approval): enable TreatWarningsAsErrors; add create conflict checks or rename to Upsert semantics; inject a key ID generator for determinism; add audit/metrics for seed refresh; add unit tests covering validator error paths, rotate/revoke flows, and audit metadata.
+- Disposition: pending implementation (non-test project; apply recommendations remain open).
+### src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/StellaOps.IssuerDirectory.Core.Tests.csproj
+- MAINT: Test project lacks Microsoft.NET.Test.Sdk and xUnit packages; discovery/running may rely on transitive TestKit behavior and is brittle. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/StellaOps.IssuerDirectory.Core.Tests.csproj`
+- MAINT: IssuerDirectoryClient tests live in Core.Tests and use reflection to instantiate internal client types, which couples tests to internal implementation details. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/IssuerDirectoryClientTests.cs`
+- MAINT: Some fake repositories throw NotImplementedException for list methods; untested paths can mask regressions when list endpoints are exercised. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerKeyServiceTests.cs`, `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerTrustServiceTests.cs`
+- TEST: Coverage exists for create/update/delete flows, key add/rotate/revoke, trust set/get/delete, and client header/cache behavior. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerDirectoryServiceTests.cs`, `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerKeyServiceTests.cs`, `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerTrustServiceTests.cs`, `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/IssuerDirectoryClientTests.cs`
+- TEST: Missing coverage for list ordering/dedup, key validation failure paths (invalid material/expired keys), and audit metadata contents for seed refresh. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerDirectoryServiceTests.cs`, `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Core.Tests/Services/IssuerKeyServiceTests.cs`
+- Proposed changes (optional): add test SDK/xUnit packages explicitly; move client tests to the client test project and expose internals via InternalsVisibleTo or a factory; implement fake list methods or add coverage for list semantics; add validator and audit metadata tests.
+- Disposition: waived (test project; no apply changes).
+### src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Infrastructure/StellaOps.IssuerDirectory.Infrastructure.csproj
+- MAINT: TreatWarningsAsErrors is disabled, reducing warning discipline in a core infrastructure library. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Infrastructure/StellaOps.IssuerDirectory.Infrastructure.csproj`
+- MAINT: InMemory key/trust repositories build cache keys as `${tenant}|${issuer}` without escaping; tenant/issuer values containing `|` can collide. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Infrastructure/InMemory/InMemoryIssuerKeyRepository.cs`, `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Infrastructure/InMemory/InMemoryIssuerTrustRepository.cs`
+- MAINT: InMemoryIssuerAuditSink discards entries silently once MaxEntries is exceeded; no metrics or visibility when truncation occurs. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Infrastructure/InMemory/InMemoryIssuerAuditSink.cs`
+- MAINT: Seed loader accepts data without validating required URL fields beyond Uri construction; bad inputs surface as UriFormatException without field context. `src/IssuerDirectory/StellaOps.IssuerDirectory/StellaOps.IssuerDirectory.Infrastructure/Seed/CsafPublisherSeedLoader.cs`
+- TEST: No test project for Infrastructure; seed loader and in-memory repositories lack coverage for ordering, collision, and parsing failures.
+- Proposed changes (pending approval): enable TreatWarningsAsErrors; escape key segments in in-memory stores; emit a counter or log when audit entries are dropped; add explicit validation errors for seed fields; add tests for seed parsing and in-memory ordering/collisions.
+- Disposition: pending implementation (non-test project; apply recommendations remain open).

+# Attestor Infrastructure Tests AGENTS
+
+## Purpose & Scope
+- Working directory: `src/Attestor/__Tests/StellaOps.Attestor.Infrastructure.Tests/`.
+- Roles: QA automation, backend engineer.
+- Focus: deterministic unit tests for infrastructure services (repositories, canonicalization, Rekor clients).
+
+## Required Reading (treat as read before DOING)
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/attestor/architecture.md`
+- `docs/modules/attestor/rekor-verification-design.md`
+- `docs/modules/platform/architecture-overview.md`
+- Relevant sprint files.
+
+## Working Agreements
+- Keep tests deterministic (fixed time/IDs) and offline by default.
+- Avoid network or external services unless explicitly mocked.
+- Update `docs/implplan/SPRINT_*.md` and the local `TASKS.md` when starting or completing work.
+
+## Testing
+- Use xUnit + FluentAssertions + Moq with deterministic fixtures.
+- Cover pagination/continuation tokens, canonicalization ordering, and client proof handling.

+# Attestor Verify Tests AGENTS
+
+## Purpose & Scope
+- Working directory: `src/Attestor/__Tests/StellaOps.Attestor.Verify.Tests/`.
+- Roles: QA automation, backend engineer.
+- Focus: signature verification, issuer trust, transparency proof evaluation, and policy aggregation for Attestor.Verify.
+
+## Required Reading (treat as read before DOING)
+- `docs/modules/attestor/architecture.md`
+- `docs/modules/platform/architecture-overview.md`
+- Relevant sprint files.
+
+## Working Agreements
+- Determinism is mandatory: fixed timestamps, stable IDs, deterministic ordering.
+- Keep tests offline-friendly and avoid wall-clock delays.
+- Update `docs/implplan/SPRINT_*.md` and local `TASKS.md` when starting or completing work.
+
+## Testing
+- Use xUnit + FluentAssertions + TestKit; prefer deterministic fixtures.

+# AGENTS
+## Role
+PostgreSQL persistence layer for Excititor VEX statements, linksets, providers, and raw documents.
+## Scope
+- Repository implementations for VEX statements, deltas, observations, providers, attestations, raw documents, and connector state.
+- Append-only linkset and checkpoint storage for deterministic replay and reconciliation.
+- Data source configuration and migration resources for the Excititor schema.
+## Participants
+- Excititor WebService and Worker for CRUD and reconciliation operations.
+- Connector ingestion and export flows for raw document storage and provider state.
+- Tests in `../StellaOps.Excititor.Persistence.Tests`.
+## Interfaces & contracts
+- `IVexStatementRepository`, `IVexDeltaRepository`, `IVexRawStore`, `IVexProviderStore`, `IVexObservationStore`, `IVexAttestationStore`, `IVexTimelineEventStore`.
+- `IAppendOnlyLinksetStore`, `IAppendOnlyCheckpointStore`, `IVexConnectorStateRepository`.
+- Database schema and migrations in `Migrations/*.sql`.
+## In/Out of scope
+In: persistence models, SQL schema/migrations, deterministic ordering guarantees.
+Out: connector ingestion logic, policy evaluation, and HTTP workflows.
+## Observability & security expectations
+- Log persistence failures with tenant/source identifiers; do not log raw document payloads.
+## Tests
+- Integration tests live in `../StellaOps.Excititor.Persistence.Tests` and must be deterministic and offline-friendly.
+
+## Required Reading
+- `docs/modules/excititor/architecture.md`
+- `docs/modules/platform/architecture-overview.md`
+
+## Working Agreement
+- 1. Update task status to `DOING`/`DONE` in both correspoding sprint file `/docs/implplan/SPRINT_*.md` and the local `TASKS.md` when you start or finish work.
+- 2. Review this charter and the Required Reading documents before coding; confirm prerequisites are met.
+- 3. Keep changes deterministic (stable ordering, timestamps, hashes) and align with offline/air-gap expectations.
+- 4. Coordinate doc updates, tests, and cross-guild communication whenever contracts or workflows change.
+- 5. Revert to `TODO` if you pause the task without shipping changes; leave notes in commit/PR descriptions for context.

+# ExportCenter Tests Agent Charter
+
+## Mission
+Validate ExportCenter behaviors with deterministic, offline-friendly tests across core, infrastructure, and adapters.
+
+## Responsibilities
+- Cover planners, adapters, bundles, retention, scheduling, and verification flows.
+- Enforce deterministic fixtures (fixed time, stable IDs, stable ordering).
+- Keep tests isolated from network and external services.
+
+## Required Reading
+- docs/modules/export-center/architecture.md
+- docs/modules/export-center/provenance-and-signing.md
+- docs/modules/export-center/mirror-bundles.md
+- docs/airgap/offline-bundle-format.md
+- docs/modules/platform/architecture-overview.md
+
+## Definition of Done
+- Tests include success and error paths for core services and adapters.
+- Fixtures avoid Guid.NewGuid/DateTimeOffset.UtcNow unless fixed.
+
+## Working Agreement
+- 1. Update task status to DOING/DONE in the sprint file and local TASKS.md.
+- 2. Review this charter and required docs before coding.
+- 3. Keep tests deterministic; clean up temp files and directories.
+- 4. Keep outputs offline-friendly (no network).
+- 5. Revert to TODO if paused; capture context in PR notes.

+
+## Definition of Done
+- Endpoints and background job handlers are deterministic and testable.
+- In-memory or sample handlers are behind explicit dev/test gates.
+- Tests cover endpoint behavior, SSE streaming, and job lifecycle flows.
+
+## Working Agreement
+- 1. Update task status to DOING/DONE in the sprint file and local TASKS.md.
+- 2. Review this charter and required docs before coding.
+- 3. Prefer TimeProvider and deterministic ID generators over DateTimeOffset.UtcNow/Guid.NewGuid.
+- 4. Keep outputs stable (sorted lists, stable timestamps) and offline-friendly.

+# Feedser Core Tests Agent Charter
+
+## Mission
+Validate Feedser patch signature and function extraction behavior with deterministic unit tests.
+
+## Responsibilities
+- Maintain test coverage for HunkSig extraction and function signature matching.
+- Ensure tests are deterministic and avoid time-sensitive assertions.
+- Keep fixtures minimal and offline-safe.
+
+## Required Reading
+- docs/modules/feedser/architecture.md
+- docs/modules/platform/architecture-overview.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+
+## Definition of Done
+- Tests cover parsing, normalization, and matching behavior.
+- Tests remain deterministic across runs and environments.
+- Failures provide actionable diagnostics.
+
+## Working Agreement
+- 1. Update task status to DOING/DONE in the sprint file and local TASKS.md.
+- 2. Review this charter and required docs before coding.
+- 3. Avoid DateTimeOffset.UtcNow/Guid.NewGuid in tests unless explicitly controlled.
+- 4. Keep outputs stable (ordering, timestamps, hashes).
+- 5. Revert to TODO if paused; capture context in PR notes.

 ## Token format
 
-`replay:v<version>:<algorithm>:<sha256_hex>`
+v1 (no expiration):
+
+`replay:v1.0:<algorithm>:<sha256_hex>`
 
 Example:
 
 `replay:v1.0:SHA-256:0123abcd...`
 
+v2 (includes expiration):
+
+`replay:v2.0:<algorithm>:<sha256_hex>:<expires_unix_seconds>`
+
 ## Usage
 
 - Create a `ReplayTokenRequest` with feed/rules/policy/input digests.
 - Call `IReplayTokenGenerator.Generate(request)` to get a stable token value.
-- Store the token’s `Canonical` string alongside immutable decision events.
-
+- Store the token's `Canonical` string alongside immutable decision events.
+- `ReplayToken.Parse` uses `DateTimeOffset.UnixEpoch` for `GeneratedAt` because the canonical format does not include generation time.

+# Infrastructure EfCore Agent Charter
+
+## Mission
+- Provide deterministic, tenant-safe EF Core infrastructure shared across modules.
+
+## Responsibilities
+- Keep DbContext wiring secure and consistent (schema, tenancy, UTC session).
+- Validate configuration inputs and avoid production-only diagnostics in common paths.
+- Maintain tests for interceptors, context options, and tenant accessors.
+
+## Required Reading
+- docs/modules/platform/architecture-overview.md
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+
+## Definition of Done
+- Connection/session configuration is deterministic and safe.
+- Configuration validation is explicit and tested.
+- Tests cover tenant context, session settings, and schema wiring.
+
+## Working Agreement
+- 1. Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- 2. Review required docs before changes.
+- 3. Keep session configuration deterministic (UTC, schema, tenant).
+- 4. Avoid enabling detailed errors in production by default.

+# Auth Security Tests AGENTS
+
+## Purpose & Scope
+- Working directory: `src/__Libraries/__Tests/StellaOps.Auth.Security.Tests/`.
+- Roles: QA automation, backend engineer.
+- Focus: DPoP proof validation, nonce/replay caches, and edge-case coverage.
+
+## Required Reading (treat as read before DOING)
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/modules/authority/architecture.md`
+- Relevant sprint files.
+
+## Working Agreements
+- Keep tests deterministic (fixed time/IDs, stable ordering).
+- Avoid live network calls and nondeterministic RNG.
+- Update `docs/implplan/SPRINT_*.md` and local `TASKS.md` when starting or completing work.
+
+## Testing
+- Use xUnit + FluentAssertions + TestKit.
+- Cover validator error paths, nonce stores, and replay cache semantics.

+## Definition of Done
+- Tests are deterministic and do not require network access.
+- Fixtures remain stable and are copied to output reliably.
+- Test metadata accurately reflects scope (unit vs integration).
+
+## Working Agreement
+- 1. Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- 2. Review required docs before changes.
+- 3. Prefer fixed IDs/timestamps and isolated temp directories.
+- 4. Avoid process-wide env var mutations unless isolated.

+# Reachability Integration Tests Agent Charter
+
+## Mission
+- Validate reachability corpus parsing and reachability evidence semantics.
+
+## Responsibilities
+- Keep corpus-driven tests deterministic and fixtures validated.
+- Ensure missing corpus data produces explicit skips or failures as intended.
+
+## Required Reading
+- docs/07_HIGH_LEVEL_ARCHITECTURE.md
+- docs/modules/scanner/architecture.md
+- docs/reachability/README.md
+
+## Working Directory & Scope
+- Primary: src/__Tests/Integration/StellaOps.Integration.Reachability
+- Allowed shared projects: src/__Tests/reachability
+
+## Testing Expectations
+- Avoid silent returns; use explicit skip messages if corpus missing.
+- Ensure ground-truth assertions validate both reachable and unreachable cases.
+
+## Working Agreement
+- Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- Keep fixture paths deterministic and avoid environment-specific behavior.

+# Infrastructure Postgres Testing Agent Charter
+
+## Mission
+- Provide deterministic PostgreSQL integration test fixtures and helpers for module tests.
+
+## Responsibilities
+- Maintain Testcontainers setup, schema isolation, and migration helpers.
+- Keep skip behavior safe when Docker/Testcontainers are unavailable.
+- Align defaults with StellaOps.Infrastructure.Postgres and devops Postgres settings.
+
+## Required Reading
+- docs/modules/platform/architecture-overview.md
+- docs/db/README.md
+- src/__Libraries/StellaOps.Infrastructure.Postgres/AGENTS.md
+
+## Working Directory & Scope
+- Primary: src/__Tests/__Libraries/StellaOps.Infrastructure.Postgres.Testing
+- Allowed shared libs/tests: src/__Libraries/StellaOps.Infrastructure.Postgres, src/__Libraries/__Tests/StellaOps.Infrastructure.Postgres.Tests
+
+## Determinism & Guardrails
+- Use fixed schema naming or deterministic suffixes for repeatable logs.
+- Keep SQL and fixture behavior deterministic (UTC, stable ordering, no random defaults in assertions).
+- Pin or allow override of the Postgres container image; avoid network calls beyond container startup.
+
+## Testing Expectations
+- Provide smoke tests or usage samples for fixtures where feasible.
+- Test collections must serialize when sharing a database.
+
+## Working Agreement
+- Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
+- Avoid non-ASCII log output and keep error messages actionable.
