Mythic Masters: friends walk the open world together, cheap by design, hill climb to 8/10, rounds 16+ (from #3785) #3792
Description
Score: 4.25/10 (target 8, on the owner's scale: agent judges halve their number, per the 2026-11-05 reset)
Carries the climb on from #3785 (round 15, PR #3789: the speed check from a trusted anchor, a second tab keeps the flag, vouch retells contracts), #3764 (round 14, PRs #3776, #3778, #3782: a pose speed check, stones and arenas by distance, trailheads and trail dens over the clock), #3722 (round 13, PR #3761: dens checked against the world seed), #3707 (round 12, PR #3716: the room under workerd), #3703 (round 11) and rounds 3 to 10 (#3699, #3698, #3696, #3695, #3690, #3684, #3679, #3674), all in PR #3676, and rounds 1 and 2 (#3670, #3663, PR #3669, merged); their score comments have the judges' tables. Open: MANUAL RUN #3697, #3790 (vouch retells dens; trust returns when a trusted friend walks up), #3791 (a jump believed only at a landing spot you could reach), #3706 (the lobby end to end), #3704 (full-party frame time).
The owner's brief (2026-11-05): make Mythic Masters' open world multiplayer, and make it awesome, performant and cheap. Today the whole game runs in the page on an assets-only Worker (apps/mythic-masters/rustybuns.config.ts); nothing online but eqosys sign-in (src/account.ts). The 77 × 51 km continent, its regions, trails, dens and hunts are in src/world/ and docs/WORLD-EXPANSION.md. The sibling climb for frame time is #3664.
What awesome means here
You see your friends walking the same land with their bound beasts beside them, you meet them at a den, a mythic you both chase is the same mythic, the Book heckles the party as one, and joining takes one code. Not an MMO: a party of up to six on one region at a time, like a hunting trip.
Goalpost: 8/10 from the owner
- Walk together. Through an eqosys party code (
partyin@rustybuns/util/eqosys, Qollab is the connecting layer, eqosys the account) friends land in the same region and see each other move, with their lead beast beside them, at a smooth 60 fps: interpolation and dead reckoning on the page, a low send rate (5 Hz or less, deltas, quantised positions), never a per-frame message. - One world. Dens, wild food, flocks and the region's mythic are the same for everyone there: seeded by the room, not by each page, so a hunt one player starts the others can join; a fight is still the page's own sim, its result reported and checked for plausibility.
- Cheap by design, priced before it ships. One Durable Object per occupied region (never per player) using
Socketsfrom@rustybuns/util/roomwith WebSocket hibernation, token-checked joins (@rustybuns/util/token),TokenBucket,RoomMintGateandoriginAllowedfrom@rustybuns/util/limits, no storage writes per tick (the room keeps state in memory, a save is the player's own page). A cost model in the repo (apps/mythic-masters/scripts/cost.ts) that runs the stress script, counts messages, wake time and storage ops, and prints a price per player-hour from Cloudflare's published Durable Object rates. Target: under $0.005 per player-hour at a full party, printed in every round's comment. No deploy by a worker: the owner runsbun run deployafter a plan (DEPLOYS=1 AGENTS=1 CHECKS=1). - Honest offline. Alone, nothing changes: no socket, no cost, the save stays local. A dropped connection degrades to solo play and rejoins without losing the trip.
- Tested the way people play. One journey test through the running app (
local()fromtest/app-kit.ts) with two pages in one room: both see each other, one leaves and rejoins, a hunt stays shared. A stress script (scripts/stress.ts) that runs six bots walking a region for a minute and prints messages per second and the price.
The loop
Each round is one PR against main that says "Part of #N". Shots and numbers: bun run probe mythic-masters with the mythicMasters handle, two headless pages in one room, frame time and bytes per second per player in the comment. A fresh judge scores the five points, halves it, and the comment starts Score: x/10 (target 8) and ends Next: ...; then open "rounds N+ (from #N)", close this one with "Moved up to #new". At the target, a MANUAL RUN: for the owner's own play with a friend. No Vectorize, no third-party realtime service, no new paid binding without an issue for the owner first.

Round 15: PR #3789 (open, CI green on its first commit). It closes the three holes in #3784:
vouchand the page tells its contracts again.A fresh judge gave 8.5/10, against 8.75 last round. So the score is 4.375 + (8.5 − 8.75) / 2 = 4.25. The judge's top gap was one this round made: a network stall followed by a burst of poses flagged an honest fast runner. It is fixed in the same PR (time banked during a stall carries through the burst, with a test row), after the judging, so the score doesn't count the fix.

Round 16. Round 15's two Next items merged without a score of their own: #3797 (a jump is believed only at a landing spot in a region the save has opened, #3791) and #3801 (trust coming back retells the den, and a trusted friend walking up brings it back, #3790). The lobby end to end landed too, in #3806. This round scores main with all three, then builds the judge's second gap in PR #3860. The top gap, a full party's frame cost (#3704), is the frame-budget climb's (#3796), so it stays there.
A fresh judge gave 8.0/10, against 8.5 last round. So the score is 4.25 + (8.0 − 8.5) / 2 = 4.0. The judge looked harder at "one world" this time: the room relayed

A full party still misses 60 fps, and the test only asserts under 50 ms.plausible. But the room only relays page claims.

Issue-runner check (2026-11-06). Rounds since the last score: #3790 (#3801, trust coming back retells the den, and a trusted friend walking up brings it back) and #3791 (#3797, a jump is believed only at a landing spot in an opened region) both merged.
Found while measuring: the two-page Chrome journey (
test/together.test.ts, skipped on CI) failed on main at #3801's step. B met a wild one on its walk to A, lost, and the Book's talk held its poses back, so the room never vouched for A. The trust code was fine. PR #3861 has both pages walk in peace, and the journey passes again (65 s).Price, unchanged:
bun scripts/cost.ts 6 60is $0.00125 per player-hour; 89.2 B/s up and 1168.4 B/s down per player with six together.No new judge score this pass (the last is 4.25/10). Next: a fresh judge on the five points with #3801, #3797 and #3861 in. The judge's "Tested the way people play" gap still holds: the Chrome journey never runs on CI.
