| 1 | `2026-08-03-em-planner-foundation-implementation.md` | Task 2 — Configuration, Diagnostics, and Request Validation | `b326431` | RED: `foundation` failed with missing configuration/validation types; GREEN: `foundation` printed `PASS foundation` twice with byte-identical stdout and exit 0. |
| 1 | `2026-08-03-em-planner-foundation-implementation.md` | Task 3 — Direction Segmentation and Exact Boundary Anchors | `e492e16` | RED: `segmentation` failed with missing `ReferencePathSegmenter`; GREEN: `foundation` and `segmentation` each printed their PASS line with exit 0. |
| 4 | `2026-08-03-em-planner-osqp-backend-implementation.md` | Task 4 — OSQP Solve Lifecycle and Status Mapping | `a957fda` | RED: `osqp-loader` failed with missing `OsqpNativeSolver`; GREEN: fixed bounded, equality, infeasible and one-tick time-limit QPs pass inside a copied clean-plugin process. Status values 1–11 map to the planner-neutral contract, with finite metrics and captured native status. Twenty exact `osqp` solve/cleanup cycles printed `PASS osqp-solve` and `PASS osqp-loader` on every iteration. |
| 4 | `2026-08-03-em-planner-osqp-backend-implementation.md` | Task 5 — Backend Completion Gate | `61dfa79` | RED: `osqp` was rejected by the verification-host command parser; GREEN: it runs the full solver/loader group. README now records the pinned package, deployment layout, absolute-load rule, ownership and status mapping. `dumpbin /dependents` found only Windows/runtime DLLs; an externally located working directory still loaded a copied clean plugin bundle and solved the micro QPs. |
| 5 | `2026-08-03-em-planner-lateral-ls-implementation.md` | Task 1 — Variable Layout and Exact Discrete Lateral Dynamics | `c225b17` | RED: `lateral-model` failed to build with missing `LateralVariableLayout`; GREEN: `PASS lateral-model` covered contiguous `4N-1` indices, range checks, unequal-S exact integration, station/corridor/start validation, defensive copies, and the lateral result publication contract. |
| 5 | `2026-08-03-em-planner-lateral-ls-implementation.md` | Task 2 — Normalized Objective and Linear Hard Constraints | `f703d41` | RED: `lateral-model` failed to build with missing `LateralObjectiveBuilder`; GREEN: `PASS lateral-model` inspected normalized P/q coefficients with `1e-12` comparisons, exact integration equalities, finite hard bounds, goal/gear versus rolling terminal behavior, empty-intersection early failure, and the solver-neutral fake-QP boundary. |
| 5 | `2026-08-03-em-planner-lateral-ls-implementation.md` | Task 3 — Nonlinear Geometry Evaluation and Independent Validation | `0c48a7d` | RED: `lateral-model` failed to build with missing `LateralGeometryEvaluator`; GREEN: `PASS lateral-model` covered straight and constant-curvature references in forward/reverse, full Frenet curvature, actual strictly increasing PathS, curvature/yaw-rate signs, and rejection of denominator, curvature, non-finite, and independently recomputed world-geometry violations. |
- Result: The Stage 5 `lateral-model` gate exited 0 after all three Task commits. It proves the `4N-1` layout, exact unequal-station dynamics, immutable lateral inputs/results, normalized OSQP-convention P/q assembly, finite hard corridor/derivative/trust/denominator bounds, terminal distinction, full forward/reverse world reconstruction, actual PathS, and independent validation. `optimization`, `osqp`, and all four `all-foundation` groups exited 0. The dependency list remains `KERNEL32.dll`, `VCRUNTIME140.dll`, and API-set CRT DLLs only—no MKL, CUDA or external QDLDL. `git diff --check` had no whitespace diagnostics; immediately before this checkpoint update the staging area was empty and no Stage 5 scope files were uncommitted.
- Normal-project baseline: `dotnet build ClumsyPilot/ClumsyPilot.csproj --no-restore` exits 1 only for the legacy `auto_avoidance/MultiWheelAutoAvoidance.cs` missing `NetTopologySuite` (3) and `OpenCvSharp` (1) references, plus that legacy file's duplicate-using warning. There are no EM Planner errors.
- The workspace continues to contain many unrelated Map, CoarsePath, PathSmoothing, project-file, report, and documentation changes. They belong to the user and remain untouched and unstaged.
- The existing user hunk in `ClumsyPilot/ClumsyPilot.csproj` remains preserved. Do not clean, rewrite, or stage it.
- The normal `ClumsyPilot.csproj` build remains blocked by legacy `auto_avoidance/MultiWheelAutoAvoidance.cs` references to `NetTopologySuite` and `OpenCvSharp`; do not delete or bypass legacy functionality to change this baseline.
- Confirm branch `trajplanner`, `a957fda`, `61dfa79`, `c225b17`, `f703d41`, and `0c48a7d` are ancestors of `HEAD`, and the Stage 5 progress checkpoint is present.
- Tasks 4–5 each have an independent commit and their prescribed RED/GREEN evidence.
- SQP trust-region/last-feasible fallback tests and fixed real-OSQP lateral scenarios pass; the output uses actual PathS.
-`lateral-integration`, `lateral-all`, `optimization`, `osqp`, `all-foundation`, and `git diff --check` pass; the staging area is empty; a Stage 6 progress checkpoint is committed alone.
