• The device where a player makes their login: everything on it becomes the login (and the keeper's copies from it, sent before logins were needed).
• Another device they played on as a guest: when they log in there, the game asks whether what that guest made is theirs. If it is, its islands, stickers, basket and what it did join the login, on that device and at the keeper (its copies there from before logins were needed, proved by that device's key and the new login's token), and the guest there starts afresh.
• A device that is gone, say a replaced tablet: on the admin page, Move into this login puts its copies into a player's login, and every device logged in as them gets its islands.
• Logins made in the days of secret pictures keep working on the devices logged in to them, which ask for a password the next time they reach the keeper; the admin page can set one too.
• Logins from before usernames went by the made-up name: the keeper makes it their username when it starts, so they log in as before. Two of one name keep it both, told apart by their passwords.

Doors: three woods in the Building tab, shut solid and open not, a swing turning one into the other; a friend opening and shutting one where only the owner builds, and the owner seeing it, but never turning it into another door; two of one wood stacked one above the other drawn and swung as one tall door — no lintel between the halves, the handle on the lower one, a bop on either half opening or shutting the whole, friends seeing it, and it coming away whole when picked up — while different woods or doors side by side never join.

Flying animals: where they start out; twenty minutes of flight on every kind of island without flying into a hill, a tree or a house; owls up at night and the others by day; bees at the flowers; seagulls up high; staying in when they are in a house; and a fed one following you onto your head.

Racing islands: the track flat asphalt all the way round with kerbs, a finish line and nothing standing on it, on every size of island, no other vehicles parked on its square and everyone arriving beside it; the karts on the grid just behind the line; a kart steered round flat out timing lap after lap; and the lap clock not fooled by a short cut, by going back and forth over the line, or by flying over it. Races: only from a go-kart, the computer's karts lined up on the grid, nobody moving till GO, three laps, a quick driver winning and a slow one beaten but waited for, everyone placed, the robots' karts back where they were afterwards; stopping a race, a race nobody lined up for, and a newcomer hearing of one.

Jewels: gem rocks and jewels as blocks of their own, kept in the basket and not in the toy box; a mine into a mountain on every island with them (a clear way in on a path, a wooden doorway, lamps, jewels to see in its walls and a diamond); jewels buried all over every kind of island, more on a bigger one, and none to be seen but in a mine or on a stony mountain top; any tool digging one out into the basket (the hills tool raising, lowering or flattening, a stamp put down over one) and none ever made from nothing, nor painted over; an island from before them given some, once, only where nobody can see; and the stickers and the treasures board counting them. Mining bomb: in the toy box's Building tab beside the rails, put down like a block; its fuse fizzing and sparking on the host until it pops, seen by everyone; the blast digging a small round hole in the natural ground only (never blocks, furniture, farmland or anything else players built, and never the magic floor), settling what was above it like any pick; gem rocks caught in it dropping their jewels into the basket of whoever laid it; and the boom seen and heard by friends on the island.

Shop: a price for everything in the basket, a jewel for more than a fruit; gear in levels, each dearer and better than the last; gear and coins tidied (no level or kind that does not exist, no silly sums); selling only what is in the basket; walking, running and swimming faster in running shoes and flying (up too) faster in flying gear, each leaving the other alone; roller skates slower to start than the best shoes but faster once going, rolling on and then stopping when let go, no help swimming, and worn in place of shoes (in the look, and put on one or the other), and as fast as anyone with it taken off; selling, buying and wearing through the profile, kept on the device; coins and gear kept at the keeper, from the device that changed them last, and added up when a guest's progress joins a login; and toy weapons in the look the island sees (only a real one, and only while worn), popping a blob in fewer bops at the host, from no further than each reaches (a sword and a blaster further than an arm, a blaster furthest, and none from across the meadow), King Grumble feeling a Star Hammer's bops twice, a Bomb Rod's pop bopping every monster in its blast (and none outside it) as the thrower's and taking only gem rocks' jewels, never the ground or anything built, planted or furnished, and new weapons going last so saved ones stay what they were, weapons wearing out with each swing that lands, a broken one never held (the next best instead) until fixed for less than it cost, and each drawn in the hand of every kind of player, swung with the arm; every swing (a punch, and one for each weapon) starting and ending in the pose the player had, with no jumps between, and landing when it says.

Rendering maths without a GPU: faces wind outward and enclose the block, hidden faces are skipped, corner shadows, sunlight and lamp light, and relighting a region matching lighting everything.

Picture quality: where Auto starts on a computer, a tablet, a phone and a browser without a GPU, and a chosen quality kept on any of them; slow frames stepping Auto all the way down and a chosen quality only to fewer pixels and no studs; each quality giving up the costliest finishing first; the toy materials by part (wet jelly, the darkest parts shining, satin for the rest), one per colour, a copy keeping the shader. End to end, 🖼️ Picture switched from Best to Good, Fast and Auto, with the passes, the shadows and a real photo of the island at each (the other end-to-end tests play on Fast, to keep software rendering quick).

AI friend: invited to an island, coming in under its own name and look with its pet, saying hello and answering what a friend says in their language (with what the model is told about the island, them and the talk), building a stamp when asked, walking after its friend and flying to one far off, helping a dizzy friend up and bopping a monster that comes at one; going home on a goodbye (whatever the model says), when the model says to, when left alone, and staying away from an island whose owner sent it home; by itself to the loneliest open island, and never to the shared isle, Adventure Isle — invited or by itself, nor to a stage of it just conquered; on the keeper's players list as playing now while it can come, invitations passed on to it and a busy one saying so; noticing goodbyes; dialing an island a page hosts peer to peer; its own island, on the keeper's list of open islands and visited peer to peer from a page of another server, where it builds what the model picks a layer at a time (and what a friend asks for, while they talk with it), stays when a friend says bye, and is the same island with the same owner after a restart; the tokens its models take tallied a day at a time, priced, saved and shown on the admin page; and its settings on the admin page checked, saved and applied at once (a new name from its next visit on, and the saved ones winning over the environment after a restart), the islands it is on with what is said there, a line said there as its own words (without asking the model, and seen by the model as its own afterwards), and sent home from one; with a stand-in for the model.

Ideas: a logged-in player sending ideas within their limits (none without a login, and no problem told of without one either, nor below level 5 on Adventure Isle), the answers going to that player's pages alone and never saying on a page who sent one; each read in turn by the next worker, a yes filed as a short proposal crediting the player by their display name, and its pull request too (a name in plain text), a no kind and in the player's language, one the model failed on read next time; each scored, and the player told each step its issue takes after, once and only forward; and in a page, an idea sent from Help coming back answered as a toast and in the list. A problem told of read the same way, with what the page knew but never the island's name or code, and its picture described by a vision model, a picture alone too (one it fails on read next time), a real one filed as a bug crediting the player, and no idea limit counting it.

CTB: a worker's steps reading, searching, editing and testing only inside its worktree (no path out of it, through .., an absolute path or a symbolic link, and no file it must not change); a task becoming a branch, a commit by the worker and a pull request that closes it, on real git repositories, with the worktree gone after; failing unit tests going back to the worker, and a task given up marked stuck with why; a worker waiting longer each time while Z.ai is busy, and not when it is out of credit; a proposal as an issue that starts only once labelled approved, or is turned down; the office on the CTB island with the workers sitting at their desks, the one named answering a child, nobody building there, not even its owner, the island kept over a restart, and on the list as the one to watch without a login (never a page's island); the admin page's settings, new tasks, approvals and workers. GitHub and the model are stand-ins.

Players: every animal, every kid and every grown-up (each hair style under each hat, and each grown-up's face) drawn in every pose and emote, a flying friend on someone's head sitting on top of their hair or hat (higher on a grown-up), a kid's skin and hair kept as chosen through the room and the keeper (anything unknown as a kid starts out, and none for an animal), and a grown-up a head taller than a kid standing, with their hips where a kid's are riding or sitting dizzy, and their glasses, moustache or beard kept as chosen (and none for a kid).

Pets: a pet kept in a look (any name, a coat its kind comes in, or none for a kind there is not); ten minutes following a player about on every kind of island without getting into a block or falling far behind for long, and popping over only now and then; sitting beside you when you stop, looking up at you, lying down after a while and asleep at night; waiting under you while you fly, and popping over to you when you go a long way at once or up where it cannot follow; swimming after you and climbing out onto the bank after you; riding along and hopping down beside you; posing in front of you; tricks; a parrot on your head (beside you while a bird sits there) and a baby dragon landing beside you; a parrot repeating what you say a second later, while one asleep or far behind, and every other pet, says nothing; every pet drawn in every coat and pose in its owner's colour; and a pet riding along sitting right on top of each animal and vehicle, behind its rider.

The map: the ground seen from above (looking past flowers and fruit), deeper water darker, hill shading, edits repainted with the shadow they throw, the part of a big island it follows, and directions that match the 3D view instead of mirroring it.

Monsters: off unless the owner turns them on (in Make an island or the island rules, and kept when saved, the monsters themselves never); coming out round the players, out of their reach and the start's, more at night; one chasing you, bumping some HP off you, never twice in a moment, and with none left sending you home with all of it; HP coming back; more HP with a higher level, and a level up bringing the new HP at once; popping at once when landed on, and after three bops from right up close (as far as an arm reaches, a little more for one on the move, and no further, nor at one up on a ledge), each knocking it back and making it come after you quicker than you walk, never two from you in a moment, and all its hearts back when left alone; going round a wall and the safe place round the start to get at you, never into it, the water or a tent, and never after anyone in a tent, nor out on top of one; never bumping a rider; tougher ones among them, more at night: a Big Bruiser (six bops, twice the HP a bump, three for a landing), a Spiky (nobody lands on it, four bops), a giant mosquito (the size of a pony, never touching the ground: hanging in the air out of reach of arm and jump, darting down at you quicker than you walk but never as quick as you run, nobody lands on it, two bops, and it crosses the water where the others cannot, keeping out of the safe places as they do) and a giant spider (low and wide on eight legs, hardly ever out by day and oftener at night, scuttling as quick as the mosquito darts so it catches you walking but never running, four hearts with two off for each landing on it, or four bops, and it keeps to the ground out of the water and the safe places like the others), Mr. Mole (a mound of dirt under the ground, quicker than a walk and never as quick as a run, that nothing bops, lands on or is bumped by, the dragon's fire included, popping up beside whoever he is after with a burst of dirt everyone is told of, a bump for 20 HP, three bops or one landing while up, and back under after a moment; out of the water and the safe start like the others), and on volcano islands only a Lava Ghost (floating low over the ground and across a lava lake to get at you but never over water, bumping nobody, nobody landing on it, three bops; rearing back and breathing fire the way it faces, 30 HP off whoever is in it and 15 in a Fire Suit, its fire told apart from a dragon's and every breath told to everyone on the island, friends far off too); and all gone, with everyone's HP back, when turned off.

Adventure islands: three camps on a cozy island, five on a big one and seven on a huge one, on every kind of island, and King Grumble's castle, each well away from the start and the others, on gloomy ground round a flag with room over it; a fence of logs round every camp and stone walls round the castle, each with a way in from the start to its flag; everything else just as it would be without them, every vehicle kept and no animal in a camp; a camp's monsters coming out as someone comes near (one more than there are friends, up to five, one of them a giant mosquito hanging over the camp on the wing), keeping to their camp, chasing whoever goes into it and giving up once they are well out; a flag going up only with none of its monsters in the camp and someone on foot by it, faster with more friends, a monster popped coming back a while after (the mosquito too); a camp freed with everyone there, its monsters gone, its gloomy ground grass and flowers and the camp a safe place to come back to; out of HP with a friend about, dizzy, never bumped, and helped up by a friend beside you (not from far off), or back to the start after a while; King Grumble in his bubble while a camp is not free (no bump, no bop getting through), his bubble popping with the last camp, then each friend bopping him once a moment, helpers at two thirds and a third, and the island free when he pops; his stomp knocking over whoever is on the ground near him and missing whoever is jumping; the Queen Mosquito guarding the deepest camp (many hearts, a harder bump, nobody landing on her, heavy, sent on the wire as her own kind), getting a heart back every two seconds once nobody has been near her for a few seconds and none while someone is or a bop has just landed, up to her full hearts and no more; the camps' monsters staying when the monsters rule is turned off; and the adventure kept when saved, and on the list of open islands.

Monster Gashapon and tougher monsters: ten monster figures of the island's real monsters by rarity, a rare one likelier the higher the stage (up to a point), the machine out of the toy box and nobody's to put down, pick up (put back on the picker's screen) or build over; the island putting it down a while after someone comes, near them on open ground out of the camps and facing them, taking it away after a while and putting it down again later, nothing while nobody is about, and none kept when the island is put away; a turn costing more and giving a monster figure with its stickers, every figure the real monster about a unit tall; the Grumble Knight and the Stone Golem tougher than a Big Bruiser and never as quick as you run, among a camp's guards from the stages they come in at, stage 1 as before; end to end, Q by it opening its window with the odds, a turn giving a figure into the collection and the backpack, a pick putting it back, and the window turning no more once it has gone; only the shared isle getting it, never another adventure island; and the toys and figures in the collection, none in the backpack: the Build side's showing only the capsule toys, the isle's only the monster figures.

The shared isle: each stage a little harder and none ever hopeless (camps, guards, hearts and flag times by stage, each only up to a point); one public adventure island at a time, with its own way in on the title screen, on the list with nobody on it and heading it, owned by nobody (no owner, no rules to change, anyone in); conquered, the next stage up at once with the conquered one waiting for its players and told where the next one is, then going once everyone has left it; the beginning of a day back at stage 1 however the last one was going; the island of a stage the same one all day, and the stage kept over a restart that day; each island as it comes and goes told to whoever hosts it peer to peer; over the real server, anyone joining it by WebSocket and the next stage on its list within a moment of the win; and end to end, the title screen's way in on the dedicated server, and each stage hosted peer to peer on the keeper's list for a page playing peer to peer; and end to end its world of its own: on it the isle's own profile — the level that shows there, the XP of what you do, its key kept on the device — while yours everywhere else stays as it was, and is yours again back at the title; and that world kept at the keeper as yours is, ranked live on the isle's own boards (which the ranking opens on there, and switches away from with one tap) beside the other world's, logged in.

Tower defense islands: on every kind and size of island, a road from the monsters' gate, far from the start, to the Star Stone by it, a step at a time and never more than a block up or down, on pebbles with room over them and off the start, and at least eight pads beside it within a tower's reach; everything else just as it would be without, and no road on an adventure island; a wave only on Start, out of the gate, all the way along the road bumping nobody, a heart off the Star Stone for each one there, two back for the wave and the wave tried again once it has none, with a few giant mosquitos flying among the blobs from the second wave on, more of them each wave up to five, spread through the wave and quicker along the road, each with the wave's hearts and costing the Star Stone a heart; towers built only from beside their pad and with bricks enough, their blocks set and sent, bubbles at the monsters and bricks for each one popped, by a tower or a friend (three hearts for landing on one); the road, the pads and the Star Stone never built on or dug up, the rest of the island as ever; a wave going home with nobody left on the island; towers, wave, bricks and hearts kept when saved, nonsense in a save no defense, and the wave on the list of open islands; and a whole game: a player who builds with every brick (marginally, where it adds most) sees off all ten waves with the Star Stone never running out, on cozy, big and huge islands, one who keeps half back wins too, after a few tries, and one who builds nothing never does.

Island song: named after its file, tidied; sent in pieces that each fit a message and come back whole in any order, and a piece that is not one turned away; the owner's passed on to everyone here and to whoever comes later (after the welcome, a piece sent twice passed on once), only from the owner, a new one taking the place of the old, Island music bringing the island music back for everyone, one only half sent going when the owner changes, and never in a save. End to end: picked in Settings, heard by a friend there and one who comes later, stopped for all, and played again when the island is opened again.

Room: a pet coming along in its owner's look, and petting one or giving it a fruit passed on to everyone (and nothing for a player without a pet, nor for something that is not a fruit); joining and coming back, a passcode (asked of new visitors only, guessed slowly, heard only by the owner, passed on to a new owner and kept when saved), the island on the list while it is open to new visitors, names as typed (tidied; empty, invisible or overlong ones replaced) and changed while there, island names as typed (tidied, and kept when opened again), islands of every size (a bigger one with room for more animals, and its size kept when saved), checked edits, undo, the owner's rules, phrases, stickers and typed talk (tidied, never empty or overlong, a few at once and then about one a second), animals (flying ones invited over water come in above it, sea creatures at the nearest water they can live in, big ones where there is room for them), riding (one rider at a time, nobody sending a ridden animal home, the animal going where its rider goes and staying where they get off or go home, the elephant's and the whale's tricks passed on), growing trees and fruit, weather, saving and loading (an island from before the flying animals, the sea creatures, the penguins and seals, the big animals, the jewels or the vehicles gets them, once), rate limiting.

Server: static files and path traversal, what it takes over WebSocket (frames that arrive with the handshake, nothing binary or over 4 MB, no malformed handshakes or other paths, and a path that cannot be parsed refused without taking the server down), islands of every size shared by real WebSocket clients, and its list of open islands (those with someone on them and not closed, a passcode marked, and only the right one letting a new visitor in).

Islands open now: listings tidied and sorted (the busiest first, full ones last, the one public island first), passcodes of four numbers, and the keeper's list without WebRTC (an island on it while its host's page is connected, updated, the newest word about a code winning, and off it once closed or the page goes).

Keeper: islands filed by device with one copy a day, profiles without tokens, the isle's own world of a player kept beside their profile (sent as its own kind of copy, coming back with the list, and a device's copies moved into a login bringing it along with the most of each), the IP address a page's connection uses (from its ICE candidates or the selected pair; a local one only on the keeper's own network) kept with its device and located on the admin pages, what it refuses (other games' files, damaged islands, too much, and any copy from a page with no login), the visitors' log (one entry a device, the latest first, its address noted before or after the visit, read back after a restart, shown, placed and cleared on the admin pages), its signatures, problem reports (tidied, only a real JPEG kept as the picture, a few an hour from a device, shown, marked done and deleted on the admin pages), and admin pages only the computer itself can use.

Ranking: the most first, a place shared on a tie and nobody who did none of it; the top ten and the asking player's own place further down; made-up stickers, silly counts and nameless players not counted; only players with a login, never their usernames, and leaving it holding through a new profile, a new password and a device's copies moved in; the isle's own boards (monsters popped, camps freed, King Grumbles popped, stickers, steps and XP there, nothing done elsewhere leading them) ranked apart from the other world's, from the isle's own world of each player as the keeper keeps it, with the isle's level in the rows, and a keeper from before it caught by the one board only the isle has; the protocol without WebRTC (anyone sees it, only a logged-in page leaves or joins it, the isle's world of you goes up and comes back with the list, and its ranking is asked for and watched apart); news for a page watching it of every change it would see, many changes at once as one, none for what it does not show (a watcher of one world told nothing by the other's changes), and none once it stops; a keeper older than the page saying so in its terminal, once for each kind of message it does not know; and the admin pages taking a player out and back in, and showing each one's other world.

Screen time: the lock checked, a minute after it is asked for; the keeper telling only pages that know of it, as they connect (with what is left of the minute) and as it changes, and keeping it over a restart; the admin pages locking and unlocking, with the admin header; end to end, a countdown called off by unlocking in time, then the admin page locking a page playing once it has counted down (no toy box with E), still locked after a reload, and free again once unlocked.

Players and invitations: invitations tidied, the list with who is playing now first; the keeper's list without WebRTC (only for logged-in pages, never yourself, a username or a folder, playing now while a page on screen is connected, leaving it and coming back); invitations reaching every page of the player on screen and no other, from who the keeper knows the sender is, not too often, and never to a player off the list or not playing; and an island owner's pass letting one invited friend in without the passcode, once and for half an hour, never from a visitor and never into a closed island.

Logins: making one, logging another device in with the username (in any case) and password (the same from any keyboard's spelling of it), usernames in any language taken once in any case or width and never with something invisible in them, logins from before usernames named after their made-up names, what makes a password too weak, the wait after wrong passwords, two players with one name, tokens, new passwords and logging out; a player's islands coming back to each device (newer copies win, goodbyes reach the other devices unless changed there since); merging two devices' profiles, and a guest's progress added to a login once; a device's copies from before joining a login, from the page and from the admin pages; logins from the days of secret pictures getting a password; the protocol without WebRTC (nothing secret before the keeper's signature, and pages from before logins or passwords still answered); and the admin pages' new passwords and removing a login.

Full screen: the standard calls, Safari's older prefixed ones, and iPhones and iPads, which can only get it (or keep it, on an iPad, where any swipe down ends the page's full screen) from the Home Screen.

End to end in headless Chrome: playing alone with real clicks, a bird invited from the toy box, petted with a click and fed until it sits on your head, a fish petted through the water, a pony got on with the Ride button, ridden about and got off with Q, a digger driven with the Drive button through a wall of stone (a tunnel, and the ruby in it in the basket), a kick scooter driven with the Drive button (standing on its deck, quicker than you run, its bell rung with a jump and out with Q), a gem rock dug out with a click into the basket (and kept through Undo) and its jewel put down and picked up again, a carrot from the basket planted with a click on grass (turned over into farmland), watered with the watering can from the toy box's Farm tab, and once ripe picked with a click (two carrots in the basket, and the farmland bare), a trampoline bounced on higher and higher with Space held and stopped with a press of Shift, a pet picked in My pet on the title (a brown puppy named with an emoji, which sits at your feet there) coming along to an island on the dedicated server, keeping up as you walk and sitting beside you once you stop, petted with a click, begging when you wave, and seen and petted with a click by a friend who comes, who gets a sticker for it while you are told, a huge circus tent put down from the toy box with a click and walked into through its way in, where a night is a camp out with its sticker, a thump and a puff of dust for every fall from a height, monsters turned on in Make an island (the hearts on screen, one aimed at through the tree crown the camera is in and the grass in front of it, where a click only says to bop it, and X swings at nothing from three steps off and pops it from right up close, one taking a heart and knocking you back, and all gone when turned off in Settings), the little map (a brick you build shows on it, the big map, the switch in Settings) and where it fits on screens of every shape, with the 👊 button and without, full screen and the iPhone guide to the Home Screen, two friends peer to peer through a local PeerServer (one seeing the name the other typed, the new one it changes to there and the kid with pink pigtails it turns into, and what the other types), two friends on the dedicated server, a huge island named in Korean, saved and opened again after a reload, a page that only comes by in the keeper's visitors' log until it logs in, then sends copies to it peer to peer (and nothing to an impostor under its peer id), a login made on one device logging in another (where the guest's island comes along, then the same name, look and islands both ways, owned there too, a display name of its own and the username again, until it logs out), a page nobody is logged in on showing only the way to log in (with a note while the keeper is away, and an invitation link waiting) until a login is made there, and again once it logs out, the ranking seen by a guest from the title screen, then by a player who logged in there, from ⭐ Stickers, marked as them, leaving it and coming back, and a friend logged in on another device building until they pass them, all while it stays open, the ranking from a keeper running code from before it (it needs an update, and is never live), the keeper's admin page (islands folded away until opened, and moving a gone device's copies into a login too), and an island open to friends showing up on another page's list of open islands through the keeper, given a passcode there (a wrong one asked again, the right one letting the friend in, who comes back without it), and gone from the list once closed to friends, and two logged-in players seeing each other playing now on the players list, one inviting the other to an island with a passcode from its island card and the other going from the card that pops up, without the passcode, then leaving the list, and an adventure island made with ⚔️ Adventure in Make an island, with a friend peer to peer: its camps' flags and the tally beside the hearts, a camp's monster popped with X from up close (a click only saying how, and the friend seeing the swing), its flag raised by both of them together until the camp is free for both, and the friend out of hearts sitting dizzy until the other clicks them to help them up, and a tower defense island made with 🗼 Tower defense in Make an island (Adventure turned off by it): the wave, the Star Stone's hearts and the bricks on screen, a tower built with V by a pad, the wave started with the Start button away from the pads, and the tower blowing bubbles at its monsters; a 🐞 problem told of from How to play, with a picture of the island and the hotbar over it, reaching the keeper, then one with a picture picked from the device in its place, and one told of while the keeper is away waiting in the page over a reload and going when it is back. Set CHROME_PATH if Chrome is not installed in a standard location; without Chrome these are skipped.

On a computer with a mouse the game is not in touch mode; on a touch screen, or a machine with no mouse, it is, with the thumbstick and the touch buttons on screen. To run the end-to-end tests that way, which matters for anything that moves the buttons or words a hint for touch (npm run check does both):

E2E_NO_MOUSE=1 npm test

A machine with no GPU, like a CI runner, draws in software on a slow CPU, and a frame can take seconds, so anything the tests wait for that is timed on the wall clock can run out between two frames there and never on a fast computer. On a Mac, keeping Chrome to the efficiency cores comes close to that:

CI=1 E2E_NO_MOUSE=1 taskpolicy -c background npm test

Every page a test opened is closed after it, passed or failed. A page left open keeps drawing its island in software, and the tests after it would take about three times as long, long enough to time out. An error in a page fails the test it came in, and only that one.

The pages the end-to-end tests open are in a hurry (window.kidsWorldHurry, public/js/hurry.js): the waits a player never notices, before the keeper is first called, between saves of the island and between asking for a list again, are a tenth as long. A dialog popping in is finished at once before a click, instead of waited for.
