 ## Status
 See `docs/ROADMAP.md` for milestones and `docs/ARCHITECTURE.md` for the design.
 
-Current milestone: **M0 — playable single-player world skeleton** (scaffolding on disk; needs Godot 4 installed to open & run).
+**Emberwild 0.4.0** is released (download page and player guide:
+https://emberwild-95k.pages.dev, builds on the Gitea releases). Built so far:
+- M0-M1: the island, survival, crafting, building, weather, wildlife, hunting, fishing.
+- M2: self-hosted multiplayer (Host Game, dedicated servers, rules, chat, admin).
+- P1-P5 (`docs/PROGRESSION_DESIGN.md`): iron, stone building, the wolf moon and
+  alpha, the bear, crows and foxes, the barrow, hazards, the Old Stag. P6: a use
+  for every material, lights to place, dropping items, bag rows on the hotbar.
+- T1, T2, T4 (`docs/TUTORIAL_DESIGN.md`): the tutorial with Old Tam (spoken),
+  and his tips in normal worlds.
+- M4 so far: packaged builds, the update check, music, ambience, sound effects
+  and creature voices (`assets/audio/CREDITS.md`), the trailer and help pages,
+  the map (N) and compass.
+- W0-W3, J1 (`docs/WORLDLETS_DESIGN.md`): worldlets as data, the Cove (beach,
+  pier, sea fishing), and the cliff tunnel between them, with a save file per
+  worldlet (single-player).
+Next: J3, the journey on a server ("spread out"), then the Highlands.
+Running from the source, `godot --path . -- --dev-worldlets` lets New World
+start in any worldlet, to try one directly.
 
 ## Requirements
 - **Godot 4.3+** (standard build; no C# needed — this project uses GDScript).

 # Worldlets design
 
-Status: **proposal**. Nothing here is built yet, apart from the first piece
+Status: **W0-W3 and J1 built** (the Cove without its stream yet; the
-of groundwork (`world.water_at()` and `data/fish.json`, see §6).
+tunnel single-player only); the rest is planned.
+
+*As built in J1:*
+- `scripts/world/tunnel.gd`: the seam (an outcrop on the clifftop strip,
+  7 m in from the edge, its angle from the seed) and the tunnel space, out
+  of sight 260 m under the island: a CSG rock block with the landings and
+  six sloping stretches cut out (6 m on, 4 m down each, switching back on
+  two lanes: 24 m down), then a sea cave. Faces (`tunnel_face.gd`) answer
+  like boulders, so the pick works on them: tier 3 only ("Too hard: you
+  need a better pick"), 10 blows for the seam and 15 per stretch. Each
+  stretch must be propped (2 wood, [E] at its mouth) before the next face
+  takes a blow ("It's loose..."): 10 wood all the way down.
+- Underground: no sun, moon, sky reflections or sky-tinted fog
+  (`day_night.underground`), no weather, no lake water, sheltered. Candles
+  and torch stands place anywhere on its floor and save as ordinary pieces.
+- Walking out of the sea cave's mouth travels (`world.travel()`): the
+  worldlet you leave is saved, your character and the clock go with you,
+  and the other loads, arriving at its sea cave (`sea_cave.gd`, on the
+  Cove's beach where the headland starts). [E] at the cave goes back up the
+  same tunnel to its bottom, once it's dug through.
+- Saves: `world.json` is the home worldlet's state, as before;
+  others are `worldlets/<id>.json`; meta.json's `worldlet` is where you
+  are, `home` where you began, `arrive` where the next load puts you.
+- `tests/test_tunnel.gd`: dig through, walk every stretch down and back
+  up, light it, reload, out to the Cove, back up, out at the top, and the
+  chest at home is still there.
+- Not yet: Old Tam's tip about the seam, the Guide page, and travel on a
+  server (J3: the tunnel isn't built online). The journey between
+worldlets is §10, and the two ways to play (the journey, or one land) are in
+its decisions.
+
+*As built in W3:*
+- `data/worldlets/cove.json`: low hills, mountains behind, a wide sandy
+  bay (a `beach` block) and a small pond. Not a start; its `next` is back
+  to the Valley (tunnel, J1) and on to the Highlands (sail).
+- The pier (`scripts/world/pier.gd`), a world "place" (`"places":
+  [{"type": "pier"}]`): planks on posts from where the sand is at deck
+  height to 24 m past the waterline. Worked out from the terrain, so it's
+  the same for everyone and never saved or dismantled; scenery keeps clear
+  of it. ~1.9 m of sea at its end, ~2.7 m a cast beyond.
+- Sea fish in `data/fish.json`: mackerel (common) and cod, which only bites
+  in water 2.2 m or deeper (a per-fish `min_depth`). Grilled at a campfire,
+  salted, or smoked, like the lake's.
+- New World has no "Where": the journey always begins in the Valley (the
+  Host page keeps it, for One land mode). Started with
+  `godot --path . -- --dev-worldlets`, New World and Host offer every
+  worldlet, the others marked "(testing)", to try one directly.
+- No sea stacks without a sea cliff.
+- Tests: `test_cove` (walk onto the pier, catch a mackerel off its end, cod
+  only in deep water), and the Cove in `test_terrain_edges` and
+  `test_boundary`.
+- Still to do: the stream (it needs water that runs downhill, which the
+  one flat water surface can't do: its own ribbon of water, planned with
+  the Cove's sea cave when the tunnel arrives).
+
+*As built in W2:*
+- `lake` blocks can repeat: every lake and pond is its own body
+  (`terrain.lakes`, `world.water_bodies()`), all at one surface
+  (`water_level`, set by the first). The first is still "the lake" to the
+  older code (ice, its fish, the tutorial).
+- A `beach` block (angle, width, `shore_offset`, `slope`, `current_out`,
+  `wall_out`): the land eases to a waterline and shelves gently into the
+  sea, which is then the same surface as the ponds (one ocean sheet, no
+  inland disc). The invisible wall stands well out in the water, and before
+  it a current (`terrain.current_at()`, `world._current()`) carries
+  swimmers back faster than they can swim, with a toast.
+- `water_at()` tells the sea off a beach from a pond.
+- Test-only worldlets live in `tests/worldlets/` (never listed or offered).
+  `testbay.json` (two ponds and a beach) runs through
+  `test_water_bodies`, `test_terrain_edges` (8 seeds) and `test_boundary`
+  (swimming out across the beach).
+
+*As built in W1:* a "Where" picker on the New World and Host Game pages
+(worldlets with `"start": true`; only the Valley, so it's greyed out), the
+worldlet in the Load list, and a hosted island keeps its worldlet like its
+seed.
+
+*As built in W0:*
+- `data/worldlets/valley.json`: the Valley as data, its terrain as five
+  building blocks in order (`hills`, `rim`, `sea_cliff`, `lake`,
+  `ocean_edge`) with every number that used to be hard-coded.
+- `terrain.gd` runs a worldlet's blocks (`use_worldlet()`); each block is
+  the old code's arithmetic, unchanged. `tests/test_worldlets.gd` checks
+  four seeds give exactly the same height grid as before (SHA-256 of the
+  grid, taken from the old code).
+- The worldlet is chosen like the seed: a server's (it sends its real one),
+  else the save's `meta.json` "worldlet", else the Valley (worlds from
+  before W0). New worlds and servers record it.
+- The WorldInfo API on the world: `worldlet_id()`, `water_bodies()`,
+  `climate()`, `crossings()` (the planned ways on), beside `water_at()`.
+  Systems still read the terrain's numbers directly; they move over to
+  these as each new worldlet needs them to differ (W1-W3).

    wolves sooner, or keep the same grace period everywhere?
 4. **Which second worldlet first:** Cove (sea fishing, the beach you
    mentioned) is my suggestion.
+
+## 10. The journey: tunnelling out (proposal, Nov 2026)
+
+A goal for the game, from Paul: once you have a good enough pick, you tunnel
+through the mountain rim into the next, slightly harder worldlet, and now and
+then go back to earlier ones for what only they have. This is option B
+(linked worldlets) from §2, reached by digging rather than a path.
+
+### The shape of it
+- **A chain of worldlets**, each a little harder: Valley (today's island) →
+  Cove (sea, salt, mackerel) → Highlands (cold, deep snow, bigger packs) →
+  Marsh (bog iron, sickness, mists) → the Ember, the volcanic heart the game
+  is named for: the end of the journey.
+- **The goal**, something to tell players on day 1: Old Tam talks of the
+  land beyond the mountains, where the fire in the earth still burns. Reach
+  the Ember and light the old beacon there. (Whether there's an ending or
+  it's open-ended is a question below.)
+- **Gates:** each tunnel needs the best tool from the worldlet you're in.
+  The antler pickaxe (from the Old Stag) opens the Valley's tunnel; the
+  Highlands need a pick made from something found in the Cove, and so on.
+  Each worldlet has its own boss or trial, like the Old Stag.
+
+### A different crossing each time (Paul, Nov 2026)
+Players have to work out how to get from each worldlet to the next, and
+it's a different way every time: tunnelling, climbing, burrowing, sailing.
+Each crossing is that worldlet's puzzle, and what it needs comes from what
+you've learned and gathered there:
+
+| From → to | Crossing | Needs (a first idea) |
+|---|---|---|
+| Valley → Cove | **Tunnel** through the rim at a seam | the antler pickaxe, timber props, light |
+| Cove → Highlands | **Sail** out of the bay and round the headland | a boat (planks, nails, a hide sail, rope), calm weather, food that keeps |
+| Highlands → Marsh | **Climb** a frozen cliff | climbing picks and rope, warmth to last the climb (bear cloak, pemmican) |
+| Marsh → Ember | **Burrow** under the old lava crust | a digging tool from bog iron, and a way through the heat and gas |
+
+- **The hint, not the answer:** each worldlet shows its way out without
+  explaining it: a seam in the rock with old pick marks, a wrecked boat on
+  the beach, rope frayed on a cliff ledge. Old Tam (and his tips) nudge,
+  and the guide can keep it vague.
+- **Coming back** uses the same crossing in reverse (the tunnel stays dug,
+  the boat stays moored, the rope stays fixed), so supply runs get easier
+  once you've made the way.
+- **New systems this needs, one per crossing:** digging into a rim seam
+  (tunnel and burrow share most of it), a boat you build and steer on the
+  water, and climbing a marked face. Each is a phase of its own (J1 tunnel;
+  later the sail, the climb, the burrow).
+
+### Tunnelling (the first crossing)
+- **Where:** each worldlet's rim has one or two **seams**: cracked, darker
+  rock faces with a few loose stones at the foot, findable by exploring
+  (and Old Tam's tips). The rim stays a wall everywhere else.
+- **How:** hit a seam with a good enough pick, many times. Each stretch dug
+  needs **timber props** (wood) or it falls back in, and it's dark in there:
+  candles, torch stands or a lantern. The tunnel is a short, built-for-it
+  cave (a few bends, maybe a side chamber with ore or a hazard), so it
+  stays hand-made rather than a hole through the terrain mesh, which the
+  heightmap can't do.
+- **Through:** the far end opens onto the next worldlet. Walking out loads
+  it (a short fade, "The Cove"), with your bag, cloak and stats as they are.
+
+### The first tunnel: down the sea cliff to the Cove
+The Valley's sea side ends at a sheer cliff, its top about level with the
+valley and the sea some 25 m below. The Cove is down there, so the first
+tunnel goes **down**, inside the cliff, from the clifftop to the shore.
+- **The seam:** a cracked outcrop on the clifftop strip near the edge (the
+  sea_cliff block marks where), with old pick marks and loose stones at its
+  foot. It can't be dug until you have the antler pickaxe (tier 3); a lesser
+  pick just chips it ("Too hard: you need a better pick").
+- **Digging down:** the tunnel is about six stretches, each a few metres on
+  and a few down: a sloping passage that turns back on itself like a
+  stair, so the 25 m drop fits inside the cliff. A stretch takes many pick
+  blows (stamina, and wear on the pick) to open.
+- **Props:** each new stretch needs a **timber prop** (2 wood) set at its
+  mouth before you can dig the next. Leave one out and the face won't take
+  another blow ("It's loose: prop it first"); nothing caves in on you, so
+  it's a cost, not a trap. That's 10 wood all the way down.
+- **Light:** the tunnel has no daylight at all. Every stretch is pitch dark
+  until you bring light: a torch in your hand works, but your hands are full
+  with the pick, so the way to do it is to set **candles and torch stands**
+  as you go (tallow candles from bear fat, torch stands from wood). Placed
+  lights stay, so the way is lit for the trip back and for friends.
+- **The bottom:** the last stretch breaks out into a sea cave, its mouth
+  opening on the Cove's shingle beach. Walking out of the mouth is the
+  crossing: a fade, then the Cove, arriving at the cave's Cove end. The way
+  back starts there and climbs the same tunnel.
+- **What's saved:** the tunnel belongs to the Valley's save: how far it's
+  dug, the props, the lights. On a server it's shared: anyone can dig on
+  from where someone stopped, and the lights are everyone's.
+- **How it's built:** the tunnel is its own small space (a "between" scene
+  next to the worldlet), made from a kit of rock pieces (straight, turn,
+  slope down, the cave mouth) laid out from the seed, with box-shaped
+  colliders. The heightmap can't have holes or overhangs, so the passage is
+  never cut into the terrain itself: you walk into the seam and you're in
+  the tunnel scene.
+
+### Why go back
+- **Each worldlet has things the others lack.** Clay and salt only in the
+  Valley and Cove; little wood in the Highlands; no bears outside the
+  Valley (so bear fat for candles and pemmican is a supply run); a fish or
+  herb only one place has. Food that keeps (pemmican, salted and smoked
+  meat, clay jars) becomes what you carry between them.
+- **Your bases stay** where you built them: each worldlet keeps its own
+  save file, so your Valley hut, chests and jars are waiting.
+- **Time:** a worldlet you're not in stands still (as a server does with
+  nobody on), so a base you left doesn't starve or get raided.
+
+### Building it (phases)
+| Phase | Delivers | Done when |
+|---|---|---|
+| **W0-W2** | the worldlet groundwork above (terrain pipeline, worldlet in the save, several water bodies) | as §8 |
+| **J1** | seams in the rim, digging with props and light, a tunnel scene, travel between two worldlets in single-player, per-worldlet save files | dig through from the Valley, walk to the Cove, walk back to your hut |
+| **W3** | the Cove (§5) as the second worldlet | its suites pass, and its tunnel back works |
+| **J2** | gates and supply needs: tool tiers per tunnel, resources only some worldlets have | a test bot can't open the second tunnel without the Cove's pick |
+| **J3** | multiplayer travel (see below) | two players in different worldlets on one server, or the rule we choose |
+| **J4** | Highlands, Marsh, the Ember and its ending | the journey can be finished |
+
+### Multiplayer: the hard part
+A server today runs one island. Options:
+- **Everyone together:** travel needs every player at the tunnel (like the
+  sleep rule). Simplest; one worldlet runs at a time.
+- **Spread out:** the server runs each worldlet that has someone in it.
+  The most freedom, and the most work and CPU.
+- **Party leader:** whoever goes through brings the others with a vote.
+
+### Decisions (Paul, Nov 2026)
+- **Extendable, not finished:** the Ember has a last boss, and after it you
+  keep playing. The chain is built so more worldlets (and crossings) can be
+  added after the Ember later: each worldlet names the next, nothing assumes
+  the Ember is the end.
+- **The crossings:** tunnel, sail, climb, burrow, in that order.
+- **Harder by biome, not just by numbers:** each worldlet has its own,
+  stronger animals and its own hazards. The Marsh, for one: mosquitoes whose
+  bites can make you sick, and bog, mist and the like. Others in the same
+  spirit per biome (to design with each worldlet).
+- **Multiplayer: spread out.** Each player goes where they like; the server
+  runs every worldlet someone is in, and the rest stand still. Built in J3,
+  after single-player travel works. What that means for the code:
+  - one server process holds several worldlet scenes, each with its own
+    clock, weather, creatures and save file;
+  - every player belongs to one worldlet at a time, and the server only
+    sends them that worldlet's world, creatures, sounds and chat-free events
+    (chat and the player list stay server-wide);
+  - a crossing moves a player from one worldlet to another (save their
+    place, load or wake the other worldlet, send them its world);
+  - sleep: "everyone in bed" counts the players in that worldlet only;
+  - the Old Stag and other bosses scale with the players in their worldlet.
+- **Boats: one each, no passengers.** A boat belongs to whoever built it
+  (like a bed): only the owner, and their friends under the server's locks
+  rule, can sail it, and nobody else can dismantle it. It stays moored where
+  it was last left (the Cove end or the Highlands end), so nobody is
+  stranded by someone else taking the only boat. Lose or wreck it and you
+  build another, which is harder where wood is scarce (the Highlands), so
+  plan the trip back. Each player has to earn their own crossing by boat.
+- **The other crossings are shared:** a dug tunnel, a fixed climbing rope
+  and a dug burrow are changes to the world, there for everyone once one
+  player has made them (like a door or a bridge).
+- **Two ways to play (Paul, Nov 2026).**
+  - **The journey** (the standard game), single-player and multiplayer
+    alike: every new world starts in the Valley and the worldlets come in
+    their fixed order (Valley, Cove, Highlands, Marsh, Ember). Each
+    worldlet's shape is set by its definition; the seed only changes the
+    detail (hills, trees, where the den is), so the journey is the same
+    adventure for everyone.
+  - **One land** (a hosting choice): no journey, no crossings, the server
+    is locked to one worldlet, and the host picks which, from all of them.
+    Co-op or PvP as now (the rules preset). In code: a `mode` in
+    `server.json` ("journey" / "one_land"); in one-land mode the Host
+    page's "Where" lists every worldlet rather than only the starts, and
+    the crossings (`world.crossings()`) answer none, so a tunnel seam
+    can't be dug. Kept, like the seed and the worldlet, once the island
+    exists. Worth building once the Cove exists (until then there's only
+    the Valley to pick).
+
+### Server cost, measured (0.3.1)
+One worldlet, a dedicated server on the M5 Pro, never pausing: about
+**12% of one CPU core and 270 MB of memory**, with nobody on. Players add
+creatures, weather and pickups around them. So with *spread out*, the worst
+case of 8 players in all 5 worldlets is about five of today's servers in
+one process: roughly 1.4 GB and a little over half a core before players,
+and worldlets with nobody in them stand still and cost next to nothing.
+Comfortable on the home Mac; a small cloud server (2 GB) would be tight.
+
+### (Answered) questions
+1. **The ending:** a real ending at the Ember (light the beacon, a last
+   boss, the credits) or open-ended (the journey is the goal, keep living)?
+2. **The crossings:** do the four above fit (tunnel, sail, climb, burrow),
+   and in that order? Should a worldlet have more than one way out (a hard
+   one and a long one)? And for the tunnel: only at marked seams, or
+   anywhere in the rim (more freedom, harder to make good tunnels)?
+3. **Multiplayer:** everyone together, spread out, or a party vote?
+4. **How much harder** each worldlet: stronger animals and weather only, or
+   new rules too (thirst in the Ember, sickness in the Marsh)?
+5. **Order:** Cove second (sea fishing, gentle) as planned, or straight
+   into the Highlands for a harder step?
