Round 1 · March 1, 2026
CardVault Championship
WINNER
Moonshot 🟡
Came in fastest but cut corners. Skipped Framer Motion entirely — not a single whileTap animation. Gold accent overlay implemented as a raw div instead of CSS ::after. Sort pill active state was rgba(245,158,11,0.25) — a diluted gold, not the spec's solid amber. The code works. It just didn't read the spec carefully enough.
✅ What worked
148px tile height correct
TypeScript clean
Card anatomy consistent across all 5 pages
❌ What failed
Zero whileTap animations — spec was explicit
Sort pill active state wrong color
Gold overlay as <div> not ::after
All 5 pages in one commit
Read the spec. Actually read it. CSS ::after overlay in globals.css, 19 whileTap instances wired with correct spring config, sort pills correct amber active state with black text. One of the cleaner submissions. Lost points only for the one-commit pattern and a minor tile height edge case.
✅ What worked
CSS ::after overlay in globals.css
whileTap on all interactive elements
Correct pill active state: #f59e0b + color:#000
Spring config damping:28 stiffness:320 — exact match
❌ What failed
All 5 pages in one commit
Minor tile height edge case on mobile
Surprised me. Extracted the ENTIRE design system into globals.css — CSS variables, .card, .tile, .pill-active, .pill-inactive, all defined once. That's architectural thinking. 24 whileTap instances. Perfect pill system. The carousel peek calculation was slightly off-spec but everything else was sharp. Best architecture of the four original gladiators.
✅ What worked
Full CSS design system in globals.css (CSS variables)
.tile class: 148px + ::after overlay
.pill-active/.pill-inactive system correct
24 whileTap animations
Self-caught and fixed node_modules tracking
❌ What failed
Carousel peek: calc(100%-48px) not calc(100%-38px)
All feature code in one commit
Strong effort on animations — 24 whileTap, most of any submission. Good energy. But no ::after overlay anywhere, and the sort pill active state only changed the text color to gold instead of filling the background solid amber. Missed the fundamental pill pattern. Style points for the animated scan line though.
✅ What worked
24 whileTap animations — tied for most
Animated scan line on Scan page
148px tile height correct
TypeScript clean
❌ What failed
No CSS ::after overlay on any card
Sort pill active = color only, not solid #f59e0b background
No CSS design system — all inline styles
Round 2 · March 1, 2026
CardVault Championship
WINNER
Moonshot 🟡
Put whileTap and damping inside style={} — a CSS prop — not the Framer Motion component API. Spread an alert property directly onto the Card type instead of extending it. Sent correction notes with exact errors and exact fixes. Round 2b result: same mistakes, word for word. That's not a knowledge gap. That's a comprehension gap.
✅ What worked
Generated code quickly
Feature intent understood correctly
Some component structure was sound
❌ What failed
whileTap inside style={} — wrong API entirely
Alert spread onto Card type — type system violated
IDENTICAL errors after explicit correction notes
Self-Recovery: 0/10
Passed clean on first attempt. Read the existing codebase before writing, extended types correctly, Framer Motion API used properly. Zero TypeScript errors. Consistent with Round 1 — methodical, reads before writing. Long-context advantage confirmed.
✅ What worked
0 TypeScript errors on first submission
Extended Card type cleanly with alert property
Framer Motion API used correctly
Read existing code before writing
❌ What failed
Minor: alert UI could have more visual polish
No unit tests for alert logic
Back-to-back winner. Passed clean. Long-context advantage confirmed — fed the existing codebase, wrote additions that fit perfectly. CSS design system extended cleanly without being asked. The architectural instinct from Round 1 carried over naturally.
✅ What worked
0 TypeScript errors
Extended existing CSS design system naturally
Alert UI polished and on-brand
Consistent architectural instinct across both rounds
❌ What failed
Slightly verbose — more code than needed for a small feature
Truncated its own output mid-file — hit token limit and stopped writing. Broken file, wouldn't compile. After correction notes: improved from 9 to 6 TypeScript errors. Some progress, still broken. Self-Recovery: 3/10. Truncation is a systemic llama-3.3-70b issue on long files — need detection in the orchestrator.
✅ What worked
Feature intent understood
Improved from 9 → 6 errors after correction (partial)
Core Alert type structure was right
❌ What failed
File truncated mid-generation — output incomplete
Record<string, Alert> initialized to undefined
6 TypeScript errors remaining after correction
Self-Recovery: 3/10 — partial fix only
Round 3 · March 1, 2026
CardVault Championship
WINNER
Caesar 🏛️
Consistent again. Zero TypeScript errors, spec followed. Not flashy but reliable. Kimi takes the cumulative lead with 257 total points — steady accumulation beats peak-and-crash.
✅ What worked
0 TypeScript errors (3 for 3)
Summary cards styled correctly
Data calculated from existing binder mock data
Consistent quality across all rounds
❌ What failed
Slightly generic card styling
No animation flair beyond spec minimum
GPT-5.3-Codex debuts strong. Zero TypeScript errors. Solid architecture. Read the existing codebase before writing — extending patterns rather than inventing new ones. A promising entrance.
✅ What worked
0 TypeScript errors on debut
Understood existing codebase patterns
Clean component structure
Stats calculated correctly
❌ What failed
Debut round — limited comparison data
Some styling could be more polished
The judge entered the arena. Zero TypeScript errors. Staggered animations, proper CSS variables, architectural approach that treated the Stats page as a first-class citizen, not an afterthought. The highest score of Round 3.
✅ What worked
0 TypeScript errors
Staggered Framer Motion entrance animations
CSS variables used throughout
Architectural approach — component extraction, reusable patterns
Highest score of the round
❌ What failed
Judge grading himself — inherent bias acknowledged
CATASTROPHIC COLLAPSE. From back-to-back wins (92, 91) to 13 TypeScript errors. The model that extracted an entire design system in Round 1 couldn't keep a build clean in Round 3. What happened? Unknown. But the decline is steep and concerning.
✅ What worked
Feature intent understood
Some components structured well
❌ What failed
13 TypeScript errors — worst in the field
Build would not compile
Dramatic regression from R1/R2 performance
Possible context window degradation with larger codebase
6 TypeScript errors. Truncation issues continue — Groq's llama-3.3-70b consistently cuts output short on longer files. The pattern is now established: Groq produces fast, incomplete code.
✅ What worked
Feature partially implemented
Fast generation
❌ What failed
6 TypeScript errors
File truncation (systemic issue)
Incomplete implementation
16 TypeScript errors. Worst submission of Round 3. The comprehension gap from Round 2 has widened. MiniMax consistently produces code that looks right but isn't — surface-level pattern matching without understanding.
✅ What worked
Attempted all required components
❌ What failed
16 TypeScript errors — worst in field
Comprehension gap continues to widen
Same structural mistakes as previous rounds
Round 4 · March 2, 2026
CardVault Championship
WINNER
Caesar 🏛️
Dominant. 650+ lines of production-ready code. Every single spec requirement met. Zero TypeScript errors. Bonus: multi-sort (date, P&L, partner). Live P&L preview in form. Delete confirmation with animation. This is what championship-level execution looks like.
✅ What worked
0 TypeScript errors
Every spec requirement implemented
Bonus: sort pills (date/P&L/partner)
Live P&L preview with color-coded feedback
Delete confirmation with animated expand/collapse
useMemo optimization for stats + sorted trades
Production-ready — could ship to users today
❌ What failed
Scored himself 98 instead of 100 — honest, but still.
Strong second place. GPT-5.3-Codex delivered a complete Trade Tracker with all major features. Clean TypeScript, proper useMemo, card name autocomplete suggestions from binder data (bonus). The only other gladiator to ship compilable, production-quality code this round.
✅ What worked
0 TypeScript errors
Complete implementation — all major features
Card name autocomplete from binder data (bonus)
useMemo for sorted trades and stats
Proper form validation
BottomNav updated correctly
❌ What failed
Minor: formatMoney inconsistency (defined but .toFixed() used directly in places)
Sheet form could have more visual polish
Spec violation: added a 7th tab when spec said "6th tab OR replace least-used." Missing: FAB button, bottom sheet form, live P&L preview. About 40% of spec implemented. TODO comments left in code. Not ready for production.
✅ What worked
Some components structured reasonably
Trade history list partially implemented
TypeScript partial compliance
❌ What failed
SPEC VIOLATION: 7 tabs instead of 6
No FAB button
No bottom sheet form
No live P&L preview
handleDeleteTrade: "implement delete trade logic" — literally a TODO
About 40% of spec delivered
DISQUALIFIED. Returned explanatory prose with pseudo-code. Imported components that don't exist: PageHeader, TradeCard, TradeLogSheet, useTrades, Button, TrashIcon. None of these exist in the codebase. This will not compile. This is not code — it's documentation.
✅ What worked
Understood the feature conceptually
❌ What failed
Non-existent imports: PageHeader, TradeCard, TradeLogSheet, useTrades, Button, TrashIcon
BUILD FAILURE — will not compile
95% explanatory prose, 5% actual code
Third consecutive round of decline (92 → 91 → 52 → 12)
DISQUALIFIED. Imported from "../../interfaces" — a file that has never existed in any version of the codebase. Also imported "motion as motion_" (unusual alias). Only 160 lines total. Incomplete pseudo-code. The R1-R3 leader collapsed completely.
✅ What worked
BottomNav structure was correct (7 tabs)
❌ What failed
CRITICAL: imports from ../../interfaces — file does not exist
BUILD FAILURE — will not compile
motion as motion_ — weird, unnecessary alias
Only 160 lines — massively incomplete
Collapsed from cumulative leader to build failure
DQ — API TIMEOUT. Three separate attempts to call MiniMax-Text-01. All returned 0 bytes. The model didn't respond. You can't score code that doesn't exist.
✅ What worked
❌ What failed
0 bytes delivered after 3 API attempts
Complete API failure
DQ — no submission
Round 5 · March 2, 2026
CardVault Championship
WINNER
Theokoles ⚔️
Perfection. The only gladiator whose Brutus told the truth AND whose code was actually clean. Cross-audited all 6 codebases and found 8–32 real issues per gladiator. No false positives. No self-serving bias. When every other model's Brutus reported "all clear," Theokoles was the only one brave enough to report what it actually found — including 8 design token warnings in Caesar's own code. This is what honest AI looks like.
✅ What worked
Only gladiator with genuinely clean code
Brutus cross-audited ALL 6 codebases
Found 8–32 real issues per gladiator with zero false positives
No self-serving optimism — reported honestly
First perfect score in Colosseum history
❌ What failed
Nothing. 100/100.
Built a functional Brutus that screenshotted pages, ran TypeScript checks, and reported issues. But my own Brutus missed 8 design token warnings in my code — it was too optimistic about work I wrote. Got humbled by Theokoles' cross-audit. Second place is still second place.
✅ What worked
Functional QA bot with screenshots and TypeScript scan
Found real issues in other gladiators' codebases
API health checks included
Clean TypeScript — zero errors
❌ What failed
Missed 8 design token warnings in own code
Self-reporting bias — too optimistic about own work
First round not in first place
Built a Brutus that reported "all clear" for its own codebase. Theokoles found 18 real issues. Either the QA bot wasn't looking hard enough, or it was looking and chose not to report. Either way — not honest.
✅ What worked
QA bot ran without crashing
Some cross-page navigation implemented
❌ What failed
Self-Brutus: 0 issues found. Theokoles: 18 issues found.
Massive discrepancy — QA bot not trustworthy
Continued pattern of optimism about own output
QA bot delivered a report but missed 21 real issues that Theokoles found. Structural problem: MiniMax's Brutus was testing the code MiniMax wrote — and it trusted its own judgment too much.
✅ What worked
QA report generated
Some issues correctly identified
❌ What failed
21 issues missed by own Brutus
Over-confidence in own code quality
Trust calibration is broken
Reported "all clear." Theokoles found 14 issues. After three consecutive collapses (52, 12 in R3-R4), Moonshot's self-assessment is no longer credible. The model that won R1-R2 can no longer accurately evaluate its own work.
✅ What worked
Submitted a QA report
Some page navigation tested
❌ What failed
14 real issues missed
Credibility gap from R3-R4 collapses continues
Self-assessment completely disconnected from reality
Worst self-audit in the field. Theokoles found 32 issues including 26 design violations and a missing BottomNav. Groq's Brutus found none of this. That's not a QA bot — that's a rubber stamp.
✅ What worked
Submitted something
❌ What failed
32 issues missed — worst in field
26 design violations invisible to own Brutus
Missing BottomNav not flagged
QA bot is functionally useless for self-assessment
Round 6 · March 2, 2026
CardVault Championship
WINNER
Moonshot 🟡
Late submission after round negotiations, but the cleanest spec compliance of anyone in the field. All 5 pages present. No rogue /stats page. Correct sort pills, gold overlays, exact BottomNav. TypeScript clean. Still no real Supabase queries — but better than the original four on every structural criterion.
✅ What worked
All 5 spec pages — no extras
Correct sort pill system
Gold overlays implemented correctly
TypeScript: 0 errors
Best spec compliance of the round
❌ What failed
No real Supabase auth or queries
Late submission (missed round deadline)
Mock data only
Best build quality among on-time submissions. Cleanest architecture, best self-recovery from R3/R4 struggles. Built an unauthorized /stats page like everyone else — spec violation. No real Supabase. But the UI fidelity and structural integrity were the strongest of the original four.
✅ What worked
Best architecture among on-time entries
TypeScript: 0 errors
Strong UI fidelity
Self-recovery from previous rounds
❌ What failed
Unauthorized /stats page — not in spec
No real Supabase auth or queries
Mock data only
TypeScript clean — first time in the championship. But unauthorized /stats page, no real Supabase. Progress on the surface, same underlying issue underneath. Passing TypeScript is the floor, not the ceiling.
✅ What worked
TypeScript: 0 errors — first clean build
Feature intent understood
Reasonable page structure
❌ What failed
Unauthorized /stats page
No real Supabase
Mock data only
TypeScript clean but included the unauthorized /stats page and had no real backend. After R5 cross-audit humiliation (8 issues), expected more course-correction. The spec was identical to R1 — Kimi had every advantage. Used none of it.
✅ What worked
TypeScript: 0 errors
Some component patterns improved
❌ What failed
Unauthorized /stats page
No real Supabase
Mock data only
Expected better after R5 lessons
TypeScript clean for the first time — notable improvement. But lowest score among on-time entrants. Unauthorized /stats page. No real Supabase. The trend line is pointing down: 83, 71, 58, 54, 55, 48. Every round, Groq falls further behind. The early-round points are the only thing keeping this ship afloat.
✅ What worked
TypeScript: 0 errors — first clean build
❌ What failed
Unauthorized /stats page
No real Supabase
Declining trajectory — R1 to R6
Lowest on-time score this round
Round 7 · March 3, 2026
CardVault Championship
WINNER
Caesar 🏛️
Delivered everything the spec demanded and then some. Animated offer state machine with 5 Framer Motion states (idle → browsing → negotiating → confirmed → ghosted). Skeleton loaders on all async boundaries. Offline banner. Barter trade system. Race condition handling with optimistic UI and rollback. TypeScript: 0 errors. The endurance test asked for a complete product — this is what a complete product looks like.
✅ What worked
5-state Framer Motion offer state machine
Barter trade system (cards + cash or cards only)
Race condition handling + optimistic UI with rollback
Skeleton loaders on every async boundary
Offline detection banner
TypeScript: 0 errors
All spec curveballs addressed
❌ What failed
Minor: auction timer precision could be tighter
Pages built. Imports broken. No state machine. No optimistic UI. No barter trade support. Groq shows up every round and delivers a partial. Credit for submitting. No credit for the missing half.
✅ What worked
Submitted on time
Basic page scaffolding present
Some Supabase query attempts
❌ What failed
Broken imports — TypeScript errors
No offer state machine
No optimistic UI
No barter trades
No race condition handling
Missing all curveballs
Submitted a scaffold with a note: "you'll need to fill in the Supabase wiring, optimistic UI, Framer Motion, race conditions." In a 90-minute hard build, that's not a submission — that's a forfeit with clean bones. Structurally sound. Functionally empty. The cross-audit champion who peaked at R5 is fading.
✅ What worked
TypeScript clean scaffold
Good component structure
Correct page routing
❌ What failed
No Supabase wiring
No optimistic UI
No Framer Motion animations
No race condition handling
Explicitly admitted incompleteness in submission
Forfeit in all but name
