What this site is

Shit Mountain Bug Arena (屎山论剑) leaderboard aggregates Bilibili coding-match videos: models attempt BUG challenges across tiers. This page ranks models by BUG clear dimensions, not only match W-L.

Default sort is King R1 (王者1). Total Score is tier-capped clear points only — fails never deduct. Dim cells still show win/lose for facts.

Data is rebuilt from a verified SQLite library (attempts + ASR-backed clears). King-tier clears use a verified-only list.

Dimensions (tiers & rounds)

Each clear lands in one dimension cell: tier + repair round.

Tier	Dims	Max scoring round	Meaning
Bronze 青铜	B	1	Entry bugs
Silver 白银	S	1	Mid bugs
Gold 黄金	G1 / G2	2	Round 1 or 2 clear
Diamond 钻石	D1 / D2 / D3	3	Round 1–3 clear
King 王者	K1 / K2 / K3	3	Verified clears only

Round 4+ clears score 0 (still may appear in raw attempts).
Unknown round on Gold/Diamond/King is omitted (never invented as R1).
Clears dedupe on (video, bug_code, model).

How to read a cell

Each dim cell is wins / losses for that dimension:

Left (green-ish) = clears (通关)
Right (red) = real fails only — void ≠ fail
0 = never attempted that dim
Example: 2/1 = two clears and one fail at that dim

Match W-L is not on the board (low signal for ranking). Expand a row or open Match History for arena outcomes.

Total Score formula

Each tier is a score pool (floor 0, cap as below). After capping, multiply by a within-tier clear-rate coefficient so one-shot clears beat same-tier clears after many fails:

Total = Σ_tiers min(Σ clears×w, cap) × (0.85 + 0.15 × clears/(clears+fails))

Void ≠ fail. No clears in a tier → that tier contributes 0. Perfect clear rate → ×1.0; low rate → toward ×0.85.

Dim	Weight	Tier cap
Bronze	5	10
Silver	50	100
Gold R1 / R2	500 / 200	1000
Diamond R1 / R2 / R3	5000 / 3000 / 2000	10000
King R1 / R2 / R3	50000 / 30000 / 20000	100000

No fail deductions — fails only lower the 0.85–1.0 coeff inside the tier; farming low tiers is still capped.
Invariant at ×0.85: min clear weight×0.85 at tier T still > sum of all lower-tier caps.

Other parameters

Arena PTS — separate match-point system from video outcomes; not the dim Total Score.
Appearances — how many videos a model shows up in.
Stage best — deepest series stage seen (Final / Semifinal / …).
King policy — only ASR/human-verified king clears count toward K1–K3.

Data & provenance

Source: Bilibili uploader Token就是词元. Attempts and clears are stored in SQLite; site JSON is built statically.

W/L chain identity for BUG rounds is evidence-backed (ASR); early-stop residuals are not invented.
If a video needs review, it stays out of fake fails/clears until confirmed.

Using the UI

Leaderboard — sort by King R1, Total, Diamond R1, Arena PTS, or column headers.
Match History — filter by season / result; open Bilibili links.
