+### 6.7 Map visibility controls
+
+The map view (`ui/frontend/src/lib/active-view/map.svelte`)
+carries a gear-icon popover (`map-toggles.svelte`) in the
+canvas's top-right corner, providing the player with a per-game
+visibility surface. The popover lists three groups of controls;
+every change applies within one frame (no Pixi remount):
+
+- **Objects** — six independent checkboxes: hyperspace groups,
+  incoming groups, unidentified groups, cargo routes, battle
+  markers, bombing markers.
+- **Planets** — four rows: foreign / uninhabited / unidentified
+  planet kinds plus a "show unreachable planets" switch that, when
+  off, hides every non-LOCAL planet that sits beyond
+  `FlightDistance(localPlayerDrive)` of every LOCAL planet
+  (torus-aware metric).
+- **View** — "visible hyperspace" toggle (slightly lighter
+  overlay outside the union of
+  `VisibilityDistance(localPlayerDrive)` circles around LOCAL
+  planets; LOCAL planets are always exempt — the toggle is
+  named after the visible part of the map rather than the
+  obscured one) plus the torus / no-wrap radio that switches
+  the renderer mode while preserving the camera centre.
+
+LOCAL planets are always rendered — they have no toggle. Every
+other toggle defaults to ON. Hiding a planet cascades onto every
+primitive anchored on it: battle and bombing markers on the
+planet, in-space and incoming ship-group points plus their
+trajectory lines flying *to* the planet, and cargo-route arrows
+whose source or destination is that planet. The cascade keeps
+the map free of orphan glyphs pointing at empty space.
+
+Visibility state persists per game in the
+`game-map-toggles/{gameId}` cache namespace (see
+[`ui/docs/storage.md`](../ui/docs/storage.md)). Whenever a new
+server-side turn becomes the player's current turn — either via
+`setGame` opening the player on a server `currentTurn` greater
+than the last persisted `lastResetTurn`, or via the user
+explicitly clicking the pending-turn affordance — every toggle
+is force-reset to defaults so the new turn's content cannot be
+silently hidden by a stale preference. History-mode navigation
+(`viewTurn`) keeps the shared toggle state intact across past
+turns.

+### 6.7 Управление видимостью карты
+
+Карта (`ui/frontend/src/lib/active-view/map.svelte`) несёт
+попап-«шестерёнку» (`map-toggles.svelte`) в правом верхнем углу
+канваса — посекторный интерфейс видимости для конкретной игры.
+Попап содержит три группы элементов; любое изменение применяется
+в пределах одного кадра (без перемонтирования Pixi):
+
+- **Объекты** — шесть независимых чекбоксов: группы в
+  гиперпространстве, входящие группы, неопознанные группы,
+  грузовые маршруты, метки сражений, метки бомбардировок.
+- **Планеты** — четыре строки: чужие / необитаемые /
+  неопознанные виды планет плюс выключатель «показывать
+  недостижимые планеты», который при выключении прячет каждую
+  не-LOCAL планету, отстоящую дальше
+  `FlightDistance(localPlayerDrive)` от любой LOCAL-планеты
+  (метрика учитывает торическую развёртку).
+- **Вид** — переключатель «видимое гиперпространство» (чуть
+  более светлая заливка вне объединения окружностей
+  `VisibilityDistance(localPlayerDrive)` вокруг LOCAL-планет;
+  LOCAL-планеты всегда вне фильтра — тоггл назван по видимой
+  области карты, а не по затемнённой) плюс радиогруппа
+  «торус / без переноса», переключающая режим рендерера с
+  сохранением центра камеры.
+
+LOCAL-планеты отрисовываются всегда — для них тоггла нет.
+Остальные тогглы по умолчанию включены. Скрытие планеты
+каскадно прячет все привязанные к ней примитивы: метки сражений
+и бомбардировок на этой планете, точки in-space и incoming
+ship-групп вместе с траекториями, летящих *к* этой планете, и
+грузовые стрелки, чей источник или назначение — эта планета.
+Каскад не оставляет на карте «осиротевших» меток, указывающих
+в пустоту.
+
+Состояние видимости сохраняется по игре в namespace кеша
+`game-map-toggles/{gameId}` (см.
+[`ui/docs/storage.md`](../ui/docs/storage.md)). При каждом
+новом серверном ходе, ставшем текущим — либо через `setGame`,
+обнаруживший `currentTurn` сервера выше последнего сохранённого
+`lastResetTurn`, либо при явном клике пользователя по
+аффордансу «новый ход» — все тогглы принудительно
+сбрасываются в дефолт, чтобы новое содержимое хода не оказалось
+скрытым устаревшими настройками. Навигация по истории
+(`viewTurn`) общее состояние тогглов не сбрасывает.

+
+Decisions:
+
+1. **"Reach zones" reinterpreted as `unreachablePlanets` filter.**
+   The original plan listed a "reach / visibility zones" category
+   rendered as concentric circles. The realised stage drops the
+   circle overlay and instead exposes an inverse
+   `unreachablePlanets` toggle that hides planets beyond the
+   player's `FlightDistance`. Reach is already implicit in the
+   reach-aware destination picker (Phase 16+), so the cleaner UX
+   is filtering, not adding extra rings.
+2. **Visible-hyperspace overlay**. A separate `visibleHyperspace`
+   toggle draws a slightly lighter fog over the world outside the
+   union of `VisibilityDistance` circles around LOCAL planets. The
+   fog is a renderer-level concept (layered overpaint — fog rect
+   then background-coloured circles on top — instead of Pixi's
+   `Graphics.cut()`, which produced incorrect unions of holes), not
+   a primitive: it never participates in hit-test.
+3. **Per-kind planet toggles + unidentified-group toggle**. The
+   spec's original "object visibility" list was extended:
+   foreign / uninhabited / unidentified planet kinds and
+   unidentified ship groups each get their own toggle.
+4. **Battle and bombing markers are independent toggles.** The
+   spec text grouped them as a single line item; on review the
+   player wanted finer control, so each kind gets its own
+   checkbox.
+5. **Single-blob persistence + new-turn reset.** Toggles persist
+   per game as one JSON blob `{toggles, lastResetTurn}` under
+   `game-map-toggles/{gameId}`. A new server-side turn force-
+   resets every flag to defaults so a hidden category cannot
+   silently swallow the next turn's news. History-mode
+   navigation (`viewTurn`) keeps the shared state.
+6. **Hide-by-id renderer extension.** The wrap-mode toggle keeps
+   the existing remount + camera-preserve path (it has to —
+   torus copies need different `.visible` flags). Every
+   visibility flip uses the new `setHiddenPrimitiveIds` / hide-
+   aware `hitTest` so it applies within one frame.
+7. **`pkg/calc/race.go` typo fixed**. The Go-side helper was
+   `FligthDistance`; the Phase 29 work renamed it to
+   `FlightDistance` (and the only TS call site duplicates the
+   formula directly, awaiting a future race-level WASM bridge).

+## Map visibility toggles
+
+Phase 29 adds a `mapToggles: MapToggles` rune that drives the
+gear popover in the map view. Every flag defaults to `true` —
+including `unreachablePlanets` (showing every planet by default)
+and `visibleHyperspace` (the fog overlay on by default). The
+exhaustive shape lives in `src/lib/game-state.svelte.ts`; the
+gear popover (`src/lib/active-view/map-toggles.svelte`) is a
+thin view of the rune.
+
+`setMapToggle(key, value)` flips one entry in place and
+persists the whole blob to `Cache` under the
+`game-map-toggles/{gameId}` key. The blob carries a companion
+`lastResetTurn` number — the turn at which the toggles were last
+reset to defaults — so the new-turn reset path (below) can detect
+a stale blob even across a cross-session gap.
+
+### New-turn reset
+
+A new server-side turn force-resets every toggle to defaults so a
+hidden category never makes the player miss what changed:
+
+- `setGame` reads the persisted `{toggles, lastResetTurn}` blob.
+  If `lastResetTurn < currentTurn`, the rune is overwritten with
+  `DEFAULT_MAP_TOGGLES` and the blob is rewritten with
+  `lastResetTurn = currentTurn` before the report load. Otherwise
+  the persisted overrides are restored.
+- `advanceToPending` (the user's explicit jump onto the new turn)
+  calls the same reset path after `loadTurn(currentTurn, …)`
+  succeeds, updating `lastResetTurn` to the freshly-loaded
+  current turn.
+- `viewTurn` (history mode) does NOT reset — toggles are a
+  single shared state per game, not per turn.
+- `refresh()` does not advance turns, so it does not reset.

+## Hidden primitives

+`RendererHandle.setHiddenPrimitiveIds(ids)` replaces the current
+hide-by-id set. Every primitive whose id sits in `ids` has its
+per-copy `Graphics.visible` flipped to `false` and is skipped by
+`hitAt`, so a click on its former area falls through to the next
+visible primitive. An empty set restores everything. Repeated
+calls are diff-free idempotent — `g.visible` assignments are

+
+The hide set is propagated to `hitTest` through a new optional

+## Visible-hyperspace overlay (the "fog")
+
+`RendererHandle.setVisibilityFog(circles)` draws (or removes) the
+Phase 29 fog overlay used to highlight the player's visible
+hyperspace. Each entry describes a circle around a LOCAL planet
+where the player has scanner / visibility coverage:
+
+- An empty list destroys the existing fog Graphics.
+- A non-empty list creates one fog `Graphics` per torus copy.
+  Each draws a world-sized rectangle filled with `FOG_COLOR` (two
+  shades lighter than the dark theme background), then paints an
+  opaque background-coloured circle on top for every visibility
+  circle. The overpaint order naturally unions overlapping circles
+  — earlier iterations used Pixi v8's `Graphics.cut()` to subtract
+  holes, but `cut()` produces incorrect unions for multiple
+  overlapping holes; layered repainting trades one extra fill per
+  circle for a predictable, geometry-free union.
+- The fog is inserted at the bottom of each copy's z-order so
+  primitives paint on top.
+- The fog never participates in hit-test. Planet glyphs sit on
+  top of fog, so clicks on visible planets work unchanged.
+- Wrap mode is honoured for free — `applyMode` hides every
+  non-origin copy in `no-wrap`, so the fog inherits the same
+  behaviour because the fog Graphics is a child of each copy.
+
+The map view recomputes the fog input only when the report or the
+`visibleHyperspace` toggle changes — per-frame cost stays at zero.

+ * fogPaintOps returns the ordered sequence of paint operations that
+ * draw the Phase 29 visible-hyperspace overlay. The renderer
+ * dispatches each op onto its own Pixi `Graphics` inside a single
+ * `fogLayer` that sits below every primitive copy, so the natural
+ * rendering order paints fog underneath the world.
+ *
+ * Coordinates are in world space (the `fogLayer` has no transform),
+ * which means the wrap offsets are baked directly into the
+ * positions — there is no per-tile dispatch on the renderer side.
+ *
+ * `mode` controls the torus-wrap behaviour:
+ *
+ *   - `"torus"`: every fog rect AND every visibility circle is
+ *     emitted at the nine offsets (`(dx, dy) ∈ {-1, 0, 1}²`), so
+ *     the fog covers all nine torus tiles and a planet near a seam
+ *     keeps a continuous visibility hole across it.
+ *   - `"no-wrap"`: only the central tile is emitted. The user can
+ *     never pan past the boundary in no-wrap mode, so the
+ *     additional wraps would just be wasted paint — worse, a
+ *     wrapped circle from a planet near an edge would leak into
+ *     the visible world rectangle as an unwanted hole.
+ *
+ * Empty `circles` returns an empty list — the caller skips fog
+ * rendering entirely. Width/height ≤ 0 also returns empty so a
+ * degenerate world cannot produce a non-empty op set.
