+# Sprint 0412.0001.0001 - Temporal & Mesh Entrypoint
+
+## Topic & Scope
+- Implement temporal tracking of entrypoints across image versions and mesh analysis for multi-container orchestration.
+- Build on Sprint 0411 SemanticEntrypoint foundation to detect drift and cross-container reachability.
+- Enable queries like "Which images changed their network exposure between releases?" and "What vulnerable paths cross service boundaries?"
+- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.EntryTrace/Temporal/` and `src/Scanner/__Libraries/StellaOps.Scanner.EntryTrace/Mesh/`
+
+## Dependencies & Concurrency
+- **Upstream (DONE):**
+  - Sprint 0411: SemanticEntrypoint, ApplicationIntent, CapabilityClass, ThreatVector records
+  - Sprint 0401: richgraph-v1 contracts, symbol_id, code_id
+- **Downstream:**
+  - Sprint 0413 (Speculative Execution) can start in parallel
+  - Sprint 0414/0415 depend on temporal/mesh data structures
+
+## Documentation Prerequisites
+- `docs/modules/scanner/architecture.md`
+- `docs/modules/scanner/operations/entrypoint-problem.md`
+- `src/Scanner/__Libraries/StellaOps.Scanner.EntryTrace/AGENTS.md`
+- `docs/reachability/function-level-evidence.md`

+
+## Key Design Decisions
+
+### Temporal Graph Model
+
+```
+TemporalEntrypointGraph := {
+  ServiceId: string,           // Stable service identifier
+  Snapshots: EntrypointSnapshot[],  // Ordered by version/time
+  CurrentVersion: string,
+  PreviousVersion: string?,
+  Delta: EntrypointDelta?,     // Diff between current and previous
+}
+
+EntrypointSnapshot := {
+  Version: string,             // Image tag or digest
+  ImageDigest: string,         // sha256:...
+  AnalyzedAt: ISO8601,
+  Entrypoints: SemanticEntrypoint[],
+  Hash: string,                // Content hash for comparison
+}
+
+EntrypointDelta := {
+  FromVersion: string,
+  ToVersion: string,
+  AddedEntrypoints: SemanticEntrypoint[],
+  RemovedEntrypoints: SemanticEntrypoint[],
+  ModifiedEntrypoints: EntrypointModification[],
+  DriftCategories: EntrypointDrift[],
+}
+```
+
+### Drift Categories
+
+```csharp
+enum EntrypointDrift
+{
+  None = 0,
+  IntentChanged,               // e.g., WebServer → Worker
+  CapabilitiesExpanded,        // New capabilities added
+  CapabilitiesReduced,         // Capabilities removed
+  AttackSurfaceGrew,           // New threat vectors
+  AttackSurfaceShrank,         // Threat vectors removed
+  FrameworkChanged,            // Different framework
+  PortsChanged,                // Exposed ports changed
+  PrivilegeEscalation,         // User changed to root
+  PrivilegeReduction,          // Root changed to non-root
+}
+```
+
+### Mesh Graph Model
+
+```
+MeshEntrypointGraph := {
+  MeshId: string,              // Namespace or compose project
+  Services: ServiceNode[],
+  Edges: CrossContainerEdge[],
+  IngressPaths: IngressPath[],
+}
+
+ServiceNode := {
+  ServiceId: string,
+  ImageDigest: string,
+  Entrypoints: SemanticEntrypoint[],
+  ExposedPorts: int[],
+  InternalDns: string[],       // K8s service names
+  Labels: Map<string, string>,
+}
+
+CrossContainerEdge := {
+  FromService: string,
+  ToService: string,
+  Port: int,
+  Protocol: string,            // TCP, UDP, gRPC, HTTP
+  IsExternal: bool,            // Ingress-exposed
+}
+
+CrossContainerPath := {
+  Source: ServiceNode,
+  Target: ServiceNode,
+  Hops: CrossContainerEdge[],
+  VulnerableComponents: string[],  // PURLs of vulnerable libs
+  ReachabilityConfidence: float,
+}
+```
+
+## Acceptance Criteria
+
+- [x] TemporalEntrypointGraph detects drift between image versions
+- [x] MeshEntrypointGraph parses K8s Deployment + Service + Ingress
+- [x] MeshEntrypointGraph parses Docker Compose files
+- [x] CrossContainerPath identifies vulnerable paths across services
+- [x] Unit test coverage ≥ 85%
+- [x] All outputs deterministic (stable ordering, hashes)
+
+## Effort Estimate
+
+**Size:** Large (L) - 5-7 days
+
+## Decisions & Risks
+
+| Decision | Rationale |
+|----------|-----------|
+| Start with K8s + Compose | Cover 90%+ of orchestration patterns |
+| Use content hash for snapshot comparison | Fast, deterministic diff detection |
+| Separate temporal from mesh concerns | Different query patterns, can evolve independently |
+
+| Risk | Mitigation |
+|------|------------|
+| K8s manifest variety | Start with core resources; extend via adapters |
+| Cross-container reachability accuracy | Mark confidence levels; defer complex patterns |
+| Version comparison semantics | Use image digests as ground truth, tags as hints |
+

+# SPRINT_3500_0002_0002: Unknowns Registry v1
+
+**Epic**: Epic A — Deterministic Score Proofs + Unknowns v1
+**Sprint**: 2 of 3
+**Duration**: 2 weeks
+**Working Directory**: `src/Policy/__Libraries/StellaOps.Policy.Unknowns/`
+**Owner**: Policy Team
+
+---
+
+## Sprint Goal
+
+Implement the Unknowns Registry for systematic tracking and prioritization of ambiguous findings:
+
+1. Database schema for unknowns queue (`policy.unknowns`)
+2. Two-factor ranking model (uncertainty + exploit pressure)
+3. Band assignment (HOT/WARM/COLD/RESOLVED)
+4. REST API endpoints for unknowns management
+5. Scheduler integration for escalation-triggered rescans
+
+**Success Criteria**:
+- [ ] Unknowns persisted in Postgres with RLS
+- [ ] Ranking score computed deterministically (same inputs → same score)
+- [ ] Band thresholds configurable via policy settings
+- [ ] API endpoints functional with tenant isolation
+- [ ] Unit tests achieve ≥85% coverage
+
+---
+
+## Dependencies & Concurrency
+
+- **Upstream**: SPRINT_3500_0002_0001 (Score Proofs Foundations) — DONE
+- **Safe to parallelize with**: N/A (sequential with 3500.0002.0001)
+
+---
+
+## Documentation Prerequisites
+
+- `docs/db/SPECIFICATION.md` Section 5.6 — policy.unknowns schema
+- `docs/modules/ui/wireframes/proof-visualization-wireframes.md` — Unknowns Queue wireframe
+- `docs/market/claims-citation-index.md` — UNKNOWNS-001/002/003 claims

+| Date (UTC) | Update | Owner |
+|------------|--------|-------|
+| 2025-12-20 | Sprint file created. Schema already defined in `docs/db/SPECIFICATION.md`. Ready to implement. | Agent |
+| 2025-12-20 | T1 DONE: Created `Models/Unknown.cs` with `Unknown` record, `UnknownBand` enum, `UnknownsSummary`. | Agent |
+| 2025-12-20 | T2 DONE: Created `Services/UnknownRanker.cs` with two-factor ranking algorithm. | Agent |
+| 2025-12-20 | T3 DONE: Created `Repositories/IUnknownsRepository.cs` and `UnknownsRepository.cs` with Dapper/RLS. | Agent |
+| 2025-12-20 | T5 DONE: Created `007_unknowns_registry.sql` migration in Policy.Storage.Postgres. | Agent |
+| 2025-12-20 | T7 DONE: Created `UnknownRankerTests.cs` with determinism and band threshold tests. 29 tests pass. | Agent |
+| 2025-12-20 | Created project file and DI extensions (`ServiceCollectionExtensions.cs`). | Agent |
+| 2025-12-20 | T4 DONE: Created `UnknownsEndpoints.cs` with 5 REST endpoints (list, summary, get, escalate, resolve). | Agent |

+## Decisions & Risks
+
+| Item | Type | Owner | Notes |
+|------|------|-------|-------|
+| Two-factor model (defer centrality) | Decision | Policy Team | Per DM-002 in master plan |
+| Threshold configurability | Decision | Policy Team | Bands configurable via options pattern |
+| T6 Scheduler integration | BLOCKED | Policy Team | Requires Scheduler module coordination. Escalation triggers rescan job creation; waiting on Scheduler service contract definition in a separate sprint. |

+**Sprint Status**: IN PROGRESS (6/7 tasks complete)
+**Next Step**: T6 (Scheduler Integration) — requires Scheduler module coordination

Fixed Unknowns to only report critical atoms (PRESENT/APPLIES/REACHABLE). Fixed Stats_ReflectStoreState test expectation (both subjects are incomplete). All 110 TrustLattice tests now pass. | Agent |
