 player walk, each "planned in detail before code". The org lead asked for all six in one plan (2026-09-27), so

 - **Not chosen:** the game's own `MonumentType` (§0.7), sent by the plugin. It is authoritative, but it is a
   wire change, and nothing yet shows that substations are a type of their own.
 
+### 4.1 As built (2026-09-29; Module-Rust only, no wire change)
+
+- **Storage.** One row per label, `on` or `off`: the fleet's in `rust_settings` as `map.marker.<key>`, a
+  server's in `rust_map_overrides` under the same setting name. No schema change. The key is the label
+  trimmed, single-spaced and lower case, because the game is not consistent: the rig's map says
+  `jungle swamp` for `ue_jungle_swamp_a`. Both columns are `VARCHAR(64)`, so a label longer than 53
+  characters cannot carry a switch and the write says so. A stored word that is neither `on` nor `off`
+  follows the default above it. Unlike a layer audience, this does not narrow, because a label switch is
+  clutter control and not a security boundary. The world layer's audience still decides whether a viewer
+  gets monuments at all.
+- **Precedence.** A server's switch wins over the fleet's, and the fleet's over the built-in list, label by
+  label. Setting the fleet back to what the built-in list says deletes the row instead of storing a copy,
+  so a later change to the list reaches that label.
+- **The built-in list** (`MINOR_LABELS`, off by default): Substation, Underground Cave, Train Tunnel, Water
+  Well, Wild Swamp, Jungle Swamp, Ice Lake, Jungle Ruin, Fishing Village, Large Barn, Abandoned
+  Supermarket, Oxum's Gas Station, Mining Outpost, Ranch, and (**D213**) Canyon B, Canyon C, Lake A, Oasis A,
+  Oasis C, Mountain, Train Tunnel Link, Abandoned Cabins. **All twenty-two were read from a rig**: the
+  Carbon rig regenerated at world 6000, seed 981448696 (2026-09-29), whose map has 144 markers under 51
+  labels, including every one on the list. Mining Outpost is the `warehouse` prefab and Ranch is
+  `stables_a`. The game spells one label two ways, "Jungle ruin" on that map and "Jungle Ruin" on the
+  3000 map, which the lower-case key absorbs. *Large* Fishing Village is a separate label and stays on.
+  A 6000 world needs more than 8 GB: the rig was killed at 8 GB after "Initialized … occlusion
+  sub-chunks", ran at 8.5 GB once up, and now has a 12 GB limit.
+- **Where it is applied.** `GET /public/rust/servers/:id/map` leaves out every monument whose label is
+  hidden on that server. The website and the Android app read the same answer, so both lose the markers
+  with no client change. `map.access()` carries the merged switches. Event steps that name a monument
+  (`world.monuments`) are untouched: an event can still be placed at a substation that the map hides.
+- **Admin → Rust visibility, the live map card.** Under the fleet layer switches, **Monuments on the map**
+  is a collapsed list with a checkbox for each label found on any server's current map plus the built-in
+  list (a minor label no map has yet is still listed, so it can be decided before a wipe brings it). Each
+  server row has its own collapsed **Monuments** list of the labels on its current map, each set to
+  *Default (drawn/hidden)*, *Drawn* or *Hidden*. The page's one `PUT` carries `map.fleet.markers` and
+  `map.servers.<id>.markers`, each `{ key: true | false | null }`. `null` clears the switch.
+- **Tests:** 7 server (`map.test.js`, one of them the rig map's 51 real labels) and 8 client (`mapMarkers.test.js`, the page's pure half) — 462 and
+  66 in all.
+- **Walked 2026-09-29** on the local walk core against the Carbon rig's 6000 map. Signed in as a test admin: the
+  fleet list read 51 labels, 22 hidden. Carbon read 51/22 and the Oxide rig's 3000 map 33/11. Ticking Substation
+  on the fleet dropped both server counts by one before saving. Carbon was then set to Hidden and the page saved.
+  The rows were `map.marker.substation` = `on` (fleet) and `off` (rust-carbon), with one activity row naming both.
+  The public answer then gave Oxide 55 markers (its 31 substations back) and Carbon 31 (none). Undoing both
+  through the page deleted both rows, logged as `default` and `inherit`. The public map tab on Carbon drew
+  its 31 monuments over the Rust+ picture with no console errors (144 before the filter). The walk found one
+  cosmetic flaw, now fixed: the fleet list printed the game's lower-case "jungle swamp". It now prefers a
+  capitalised spelling. The page remounts after a save, which collapses the open lists, as it does for the rest of the page.
