| Task ID | Sprint | Status | Notes |
| --- | --- | --- | --- |

| `TRI-MASTER-0003` | `docs/implplan/SPRINT_3600_0001_0001_triage_unknowns_master.md` | DONE (2025-12-17) | Synced Signals AGENTS with Unknowns scoring/decay contracts and configuration sections. |
| `GATE-3405-011` | `docs/implplan/SPRINT_3405_0001_0001_gate_multipliers.md` | DONE (2025-12-18) | Applied gate multipliers in `ReachabilityScoringService` using path gate evidence from callgraph edges. |
| `GATE-3405-012` | `docs/implplan/SPRINT_3405_0001_0001_gate_multipliers.md` | DONE (2025-12-18) | Extended reachability fact evidence contract + digest to include `GateMultiplierBps` and `Gates`. |
| `GATE-3405-016` | `docs/implplan/SPRINT_3405_0001_0001_gate_multipliers.md` | DONE (2025-12-18) | Added deterministic parser/normalizer/scoring coverage for gate propagation + multiplier effect. |
| `SIG-CG-3104-001` | `docs/implplan/SPRINT_3104_0001_0001_signals_callgraph_projection_completion.md` | DONE (2025-12-18) | Defined `ICallGraphSyncService` contract for projecting callgraphs into relational tables. |
| `SIG-CG-3104-002` | `docs/implplan/SPRINT_3104_0001_0001_signals_callgraph_projection_completion.md` | DONE (2025-12-18) | Implemented `CallGraphSyncService` with idempotent, transactional batch projection. |
| `SIG-CG-3104-003` | `docs/implplan/SPRINT_3104_0001_0001_signals_callgraph_projection_completion.md` | DONE (2025-12-18) | Wired projection trigger in `CallgraphIngestionService` post-upsert. |
| `SIG-CG-3104-004` | `docs/implplan/SPRINT_3104_0001_0001_signals_callgraph_projection_completion.md` | DONE (2025-12-18) | Added unit tests (`CallGraphSyncServiceTests.cs`) and integration tests (`CallGraphProjectionIntegrationTests.cs`). |
