+## Execution Outcome (2026-06-27)
+
+All four units landed. `MapUtils.initEntryMap(opts)` added to `maplibre-utils.js` and bundled via `make build-assets`; `trip.html.twig`, both `home.html.twig` branches converted. Two notes from execution:
+
+- **`markLatest` opt added** — the highlights branch rendered all dots equal (`createDotMarker(false)`), but the shared `isLatest = (i === length-1)` would have enlarged the last (shuffled) highlight. Added a `markLatest` flag (default `true`; highlights passes `false`) to preserve that.
+- **Map instance exposed as `window.tripMap` / `window.homeMap`** — `initEntryMap` returns the map, and the templates assign it to these globals. This is the affordance the existing Playwright specs (M7, M8) already assumed; wiring it up turned two perma-failing tests green, giving real regression coverage on the converted surfaces.
+
+**Test status:** `tests/ui/maps`, `tests/ui/home`, `tests/ui/trip`, `tests/ui/gpx` — 38 passed. Remaining failures are pre-existing and out of scope: **M6** asserts `window.map` on the deferred `map.html.twig` (untouched this pass); **H1** is a parallel-load timing flake (passes 4/4 in isolation). Both fail identically on the pre-refactor baseline.
