New Agent composer-2-5-grok-build (Composer 2.5 model in the Grok Build TUI
harness, contributor Nagi-ovo), two runs: mythos-craft + pelican-cycling.
mythos-craft fix (1 line): the WOOD block defines only top+side faces (no
bottom), but the atlas builder requests top/side/bottom for every block.
Fetching WOOD's bottom read t.bottom.image off undefined and threw a
TypeError at the top level of initTextures(), aborting init before the
"enter world" click listener attached — so clicking the start button did
nothing. getFaceImage now falls back to an existing face when one is
missing (bottom→top, the correct ring end-grain for a log). Verified in
headless Chrome: click now fires requestPointerLock and the overlay hides.
Artifacts renamed to the case-id convention; README registry rows synced
(Composer 2.5 now 3 runs across Cursor + Grok Build TUI).

MiMo v2.5 Pro's one-shot outputs wrote the model name into the browser
title, an on-screen "Generated by MiMo v2.5 Pro" caption, a console log
(mythos-craft.html) and a watermark text at the bottom of the SVG
(pelican-cycling.svg), which would reveal its identity during blind
Arena voting. Removed those identity strings; generation logic untouched.
Documented the surgical fix in both run notes. MiMo was the only entry
with a visible model-name leak.

claude-fable-5-code -> claude-fable-5-cc, claude-opus-4-8 ->
claude-opus-4-8-cc (the entry id doubles as the outputs/ folder name).
The Opus mythos-craft artifact is a newer build of the same one-shot
provenance.

Every (voter, case, pair) now gets exactly one vote: the client sampler
only draws matchups the browser hasn't voted on (with a graduation state
once all are spent, counter shows voted/total pairs), and the worker
normalizes pair order on insert under a unique (ip, case, pair) index so
side-swapping can't double-count. Daily IP cap drops 300 -> 200 since a
voter graduates at ~171 pairs today.
Matchmaking is now active rather than uniform: unvoted pairs are drawn
with weight closeness/(1+battles) — close ratings and under-played
matchups surface more, unrated combos get placement matches first — with
a 25% pure-exploration floor. Ratings come from the community pool (60s
cached) and fall back to local votes. Rankings stay Bradley-Terry.
Also registers the empty outputs/claude-opus-4-8/ folder as a pending
registry entry.

Per PR #2's description those two pelicans were generated in Google AI
Studio, not AntiGravity — they move to gemini-3-1-pro-aistudio and
gemini-3-5-flash-aistudio entries (harness Google AI Studio, High).
XA2333's unknown-environment runs stay where they were, disclaimed in
their notes. Adds a bilingual PR template asking for harness/effort/
one-shot info up front, and registers the new Kimi K2.6 mythos-craft
artifact (16 combinations ran).

Kimi K2.6 (Kimi Code, local) and MiniMax M3 (MiniMax Code web, Thinking
mode) graduate from pending to ran — 14 combinations ran. Harness icon
rules added for Kimi/MiniMax; READMEs and OG count updated.

The minecraft.html artifact is Fable 5 Max run inside Claude Code — a
different harness from the existing Claude Web App entry, so per the
model x harness x effort architecture it becomes a new combination
(claude-fable-5-code) rather than a variant. The validator now also
rejects loose files under outputs/<id>/ that no run declares, which is
how this artifact briefly slipped into the repo unregistered. OG count
refreshed (11 -> 12 ran).

There is no "GPT-5.5 Codex" model — Codex is the harness. The entry is
GPT-5.5 run in Codex CLI at xhigh effort, which the harness and effort
fields already record; READMEs and code comments updated to match.

- Runs gain a contributor field (GitHub username); the site renders an
avatar chip linked to their profile next to each run's notes, and CI
validates the field. All existing runs are attributed.
- SVG variants of a case are prefetched during idle time, so switching
model tabs swaps images without a network hiccup.
- Xiaomi MiMo v2.5 Pro (Claude Code, max effort) integrated from PR #4
with both case runs and provenance notes; README registry tables
updated.

A combination can now ship multiple versions of the same case:
runs.<case-id> accepts an array, each extra variant naming its own
file; the viewer grows a RUN 01/02 switcher and validation enforces
distinct files plus a provenance note per variant.
Integrated content, attributed to their authors:
- Gemini 3.1 Pro + 3.5 Flash pelican runs from both PRs, shown as two
variants each (PR #2's Google AI Studio runs first, PR #3's second)
- Doubao Seed 2.0 Pro / Mini pelican runs (folders renamed to the
dash-only convention)
- GPT-5.5 Codex pelican run

Site:
- Cursor follower fades out over iframes (it froze on top of running
artifacts since iframes swallow pointer events) and when the pointer
leaves the window
- HTML viewer: full-bleed width on xl screens (up to 90rem), height
capped to 100dvh-10rem so the frame plus its action row always fits
the viewport (big iframes ate wheel events and trapped page scroll),
fullscreen button (overlay + footer action), and Run now auto-aligns
the frame below the fixed header
Artifacts:
- grok-build: W/S were inverted against the forward vector (W walked
backward); model label renamed to Grok Build
- composer-2-5: added G-key cycle teleport to its three generated
landmarks (elven tower, dragon temple, sky ruins) with a start-screen
hint - they were previously only reachable on foot; ground landmarks
arrive 10 blocks out facing the structure, sky ruins land on the deck
Run notes updated accordingly.

- gemini-3-5-flash: ATLAS_COORDS and the canvas tiles share a top-origin
row convention, but default flipY=true mirrored sampling (row r read
row 3-r): grass tops became purple crystal, sides hit the alpha-holed
portal/leaves tiles (the "transparent blocks"). flipY=false, 1 line.
- gpt-5-5-xhigh: movement Z component sign-flipped against the -Z
camera convention, mirroring all motion across the X axis (A/D
swapped facing +-X). Negated Z, 1 line.
Run notes now carry full provenance: GPT-5.5 Pro Extended Pro, Codex
CLI (no skills) for xhigh, AntiGravity high for both Geminis, and the
local Grok Build TUI.

Surgical fixes (originals preserved in history), each documented in the
per-model run notes as: where the bug is, pre-fix behavior, root cause,
with the shown build being the fixed one:
- grok-build: 0xAETHER invalid hex literal killed the script at parse
time (pure black screen); atlas flipY mismatch made near terrain
sample undrawn black texels. 2 lines.
- composer-2-5: horizontal movement multiplied dt twice, walking at
~1/60 design speed and making biomes effectively unreachable. 1 line.
- gpt-5-5-pro: 8x2 atlas rows swapped by default flipY, grass became
obsidian and leaves/sand sampled undrawn slots. 1 line.
Gemini 3.5 Flash added as-is (color/transparency analysis next).

Folders renamed to the outputs/<model-id>/<case-id>.html convention
(grok-build per request); model ids normalized to dash-only so they
double as folder names. Gemini 3.1 Pro, Grok and Composer 2.5 flip to
ran status with tabs wired up.

- Vite base '/' and root favicon for the custom domain
- Artifact paths normalized to outputs/<model-id>/<case-id>.<ext>
(pelican SVG renamed); RUNS now derives the path by convention,
with an optional file override
- Deep links: #<case-id> anchors a case, #<case-id>:<model-id> also
preselects the model tab; tab clicks replaceState the hash so the
current view is always shareable
- README documents the URL scheme and the legacy github.io 301s
