skill: switch 40250 parity skill to file-by-file 1:1 porting

Unit of work is a 40250 source unit; current-only logic is a defect;
unreachable code is not evidence. Adds per-function port-map schema,
priority by player-visible gameplay, parallel worktree rules, and a
corrected project map.

+- Root: `MT_40250_SOURCE`, else `reference_root` in `audit/manifest.json` — on this machine
+  `../40250/Server Client TMP4/ClientVS22/source` relative to the repo (quote it: the path has spaces).
+- Active sources: the `ClCompile`/`ClInclude` items in `../vs_files/*/*.vcxproj`; files not listed
+  there are not product code.
+- Many `UserInterface/` files contain CP949 bytes in comments: use `grep -a` / `grep -arn`, or plain
+  grep silently reports no match.
+- Python UI and game scripts are **not** in the source tree: they are in this repo at
+  `assets/root/*.py` (e.g. `uitarget.py`, `uitaskbar.py`) and `assets/uiscript/`.
+- Server source (for protocol questions only, not client behavior): `../40250/Server Client TMP4/Server`.
 
-Use the Visual Studio project and active preprocessor flags to distinguish reachable product code from disabled, obsolete, and third-party code.

+### Code that is not a counterpart
+
+About 100 of the 111 `project/*_system.gd` files are loaded only by their own
+`project/test_*_parity.gd` (never by the runtime). They are not implementations of 40250
+behavior and their tests are not evidence; delete them, or replace them by porting the real 40250
+code path when that path exists.
+
+## Existing evidence (historical)
+
+- `docs/CLIENT-GAP.md`, `docs/CLIENT-PARITY-AUDIT-AND-FIX-GUIDE.md`, `docs/CLIENT-40250-PORT.md`,
+  `docs/PARITY-GAP.md`: background only; trust the port-map, not their status text.
 - `oracle/run-diff-suite.sh`: Granny numerical comparison suite.
-- `project/test_*_parity.gd` and `project/*_test.gd`: existing tests; inspect assertions before treating them as evidence.
 
-## Typical verification commands
-
-Run a narrow Godot test with:
+## Verification commands
 
 ```bash
-godot --headless --path project --script project/test_name.gd
+godot --headless --path project --script <test>.gd          # most project tests
+cmake --build build-debug -j4 && ctest --test-dir build-debug --output-on-failure -j2
 ```
 
-Some scripts expect the path relative to `project/` instead:
-
-```bash
-godot --headless --path project --script test_name.gd
-```
-
-Follow the convention already used by the selected test. Always finish code changes with `git diff --check`.
+If `build-debug/CMakeCache.txt` points at another checkout path, reconfigure first:
+`cmake -S . -B build-debug -DCMAKE_BUILD_TYPE=Debug`. Always finish with `git diff --check`.
