+## 2026-06-27 Momentum Telemetry Test Installed
+
+- Installed telemetry DLL at about `03:04` local while the game was cold.
+  Installed size: `16792931` bytes.
+- Source flags for the installed test:
+  `kEnableGpsNodeMultiplierInlinePatch = true`,
+  `kEnableGpsMomentumPenaltyInlinePatch = true`,
+  `kEnableGpsQueryResultTraceHooks = true`, and
+  `kEnableGpsQueryResultRecordDump = false`.
+- `solver_weights.bin` is vanilla `1.0`, so the highway multiplier hook should
+  be neutral. The behavioral change remains the fixed ordinary-edge additive
+  penalty only: `kGpsMomentumFixedEdgePenalty = 8.0f`.
+- New telemetry is a compact `gps-momentum-summary` line emitted once per
+  completed tracked map-route query. It logs `callsA`, `callsB`, `callsTotal`,
+  `penaltyTotal`, global call counters, plus light route/result counts. The
+  counters are incremented directly in the two patched ordinary expansion caves.
+- The raw route-record dump is disabled for this run to keep logs readable.
+- The installed RED4ext log was truncated to zero before handing the game back.
+- Next test routine: launch, load the fixed car save, open the map, plot the
+  usual sequence with a few seconds between each: side job, Sinnerman, Claire,
+  custom pin. More destinations are useful only after verifying the summary
+  lines are present.
