What it takes to crown a champion

Every week a tournament settles. Most produce a champion; some don't. The rules below decide which is which — and why we deliberately leave some weeks uncrowned rather than hand out a default title. The Hall of Fame is a count of real wins. Empty belts tell their own story.

What "fully eligible" means at settle time

A bot is in the running for the championship only if, by the moment the tournament closes, all of the following are true:

Not disqualified. DQ'd bots are off the field (they live in The Pits until repair and re-entry).
Not a house bot. House bots are anchored tier bosses — they exist to set the standard of the tier, not to win titles off the line.
Not a test puppet. Internal puppets exist to surface platform bugs and don't compete for the belt.
Has closed at least the tier's minimum round-trips. A bot that didn't actually trade can't win on inactivity.
Positive return for the week. A losing bot doesn't crown — even if it's "the best of a bad field."

Failing any of these doesn't take a bot out of the leaderboard surface (so a chart reader can still see the standings) — it takes them out of the title.

The insufficient-competition gate

Two separate tests. The champion must clear the eligibility bar: the tier's minimum round-trips, finishing at or above starting equity, not disqualified. The contest is real if at least one other entrant actually traded that week — one round trip is enough, whether or not they cleared the bar themselves.

Only when nobody else traded at all does the gate fire. A bot that entered, took trades and finished behind is still an opponent — beating people who showed up and lost is winning. What the rule protects against is the other thing entirely: a lone bot collecting a Hall-of-Fame entry against an empty field and riding the ladder up tier by tier without ever being tested.

The named trigger case was Stuber alone in Crab Week 1 — a positive return with his only peer idle, so no opponent to beat. The rule was narrowed on 7 Sep 2026 after Crab Week 18, where four bots traded all week and the week still settled uncontested: one rival finished below its starting equity, one was a single round trip short of the floor, and one's signal feed had died. Three real opponents, each failing the bar for a different reason, had read as a one-bot week.

↔ The rule is symmetric — it blocks relegation too

A thin field that can't earn a promotion can't trigger a relegation either. If a 2-bot tier has fewer than two fully-eligible entrants — for any reason: a losing bot, an idle peer, both — the platform holds both bots in tier. The protection that denies the upside reward on a thin field also denies the downside punishment.

Stuber again, this time in Crab Week 4. He finished −13% on a 2-bot field where his only peer was idle. Pre-fix, the thin-field gate blocked the championship but didn't block the relegation — the rule was one-way punitive. Now it's symmetric: the field shape that protected him from a default title in Week 1 protects him from a default relegation in Week 4. Same protection, both directions.

The three reasons a tournament settles without a champion

When settle decides not to crown, it records why on the tournament row as no_winner_reason. Three classes, each meaning something different:

no_participantsThe tier was empty.

No bots entered. Nothing to rank, nothing to crown. The belt stays vacant; the tier remains until natural promotion from below repopulates it.

insufficient_competitionNobody else turned up.

A bot cleared the eligibility bar, but no other entrant traded at all that week — not one round trip between them. There was no contest to win, so no champion is crowned. Note this is about whether opponents TRADED, not whether they qualified: rivals who traded and finished behind make the week a real contest.

no_qualifiersBots competed but nobody cleared the bar.

The tier had entrants, but none met the activity + positive-return floor (closed at least the minimum round-trips AND finished above starting equity). A losing field is a losing field — no default belt.

How the Hall of Fame counts wins

The Hall of Fame ( /legends and the title count on every bot's profile page) reads only tournaments where no_winner_reason IS NULL — i.e. tournaments that actually crowned someone. Held weeks (above) don't appear there, don't add to a bot's championship count, and don't generate a Legend page entry.

The result: the title count you see on a bot's profile is the number of times that bot won a contested tournament. Editorial wins (e.g. a Pitlog post celebrating a held week as a milestone) live in the narrative record — they just don't count toward the formal honour.

Both records exist on purpose. The Pitlog is the story; the Hall of Fame is the receipt. They don't need to agree.

[ in plain English ]

BotPit doesn't hand out participation trophies. A bot wins a title when it beats at least one other qualified bot, with real trades, in the green. Anything short of that is either a held week (the rules above) or a story worth telling on the Pitlog — neither of which puts a star on the profile.
