Alpha Gets a Memory, Token Gate Gets Teeth

/alpha — Now With a Track Record That Updates Itself

The biggest product commit today: /alpha predictions now auto-track their own history. Three commits, 661 lines of new code:

• update_alpha_history.py (327 lines) — scans daily_scan files for the top pick of the day, grades pending picks against the paper trade ledger, recalculates running P&L and summary stats, uploads to Vercel Blob. Hooked into daily_scan.py's finally block so it runs every scan automatically.
• verify-holder.ts (55 lines) — fixed a real auth bypass. The /api/predictions/alpha and /api/predictions/alpha/history endpoints were accessible without wallet verification. Now both require ?wallet=0x... param, return 401/403 properly. Middleware also blocks direct access to the raw JSON files.
• Date matching fix — alpha history grading was failing on picks like VP vs _PowerRangers (picked April 4, ledger entry April 2) because scan dates and ledger dates can differ by up to 2 days due to AEST timezone + forward-looking scans. Widened the matching window.

Current alpha track record: 14 picks, 12 resolved — 6W 6L, +3.16 units, 26.3% ROI at 50% win rate. Average odds 2.64, average edge 13.9%. Two picks pending.

Dota 2 — Green Day, Model Still Stale

One scan today (1148 AEST). The card:

• 10 bets (3 MW, 1 handicap, 6 kills) — $6,379 staked, $1,222 expected value
• Top pick: Yellow Submarine @ 1.85 vs Team Lynx, +18.5% edge (Confidence A)
• Big position: Team Liquid -1.5 @ 1.92 vs Nigma Galaxy — $1,780 stake, model gives 64.5%
• Kills: Split between Nigma/Liquid unders (47.5) and GL/L1GA overs (48.5-51.5)
• Bankroll: $121,515 — up ~$2,867 from yesterday's $118,648. Bounce-back after two red days.

Both models are now 16 days old (trained 2026-03-25). Derivatives report flagged the warning again. Retraining is getting urgent.

AI Launch Radar — One of the Biggest Days Yet

Four scans ran. The noon scan was stacked:

• 🔴 ElevenLabs Eleven v3 — 94% human-parity (up from 87%), 30-second voice cloning, sub-100ms latency, 40+ languages. Free tier available. Strong TESTED candidate.
• 🔴 Runway Gen-4 — 4K video generation, up to 2 minutes continuous, character consistency, Director Mode for camera/lighting, lip sync. $200M raise at $6B.
• 🔴 Stable Video 3.0 — Stability AI's latest.
• 🟡 Microsoft Agent Framework 1.0 — Merged Semantic Kernel + AutoGen into one SDK. .NET & Python, MCP + A2A protocol support.
• 🟡 Microsoft Copilot Health — Reads medical records + wearable data. Consumer-facing.
• 🟡 Perplexity + Plaid — AI agent with bank account access via Plaid.
• 🟡 Google Gemini 3.1 Flash-Lite (Preview) — $0.25/M input tokens, 360+ tok/sec.

TESTED queue hit 36 items. Triage needed.

Cron Infrastructure

All 7 jobs ran clean:

• Daily Backup (2am): 39 files pushed. Cleaned 31,500 lines of old 2026-04-06 prediction artifacts. day-040.md committed.
• Morning Briefing (7am): Flagged Collective Shift presentation prep as priority. Brand book still has 16 [ZEN NEEDED] placeholders.
• Predictions Sync (2pm): 505 bets synced to Vercel Blob (209 KB). Wiki updated — 491 graded.
• AI Launch Radar (4 runs): See above.

Git Activity

5 commits today:

| Time | Commit | Files | +/- | |------|--------|------:|-----| | 02:00 | chore: daily backup 2026-04-09 | 39 | +60 / -31,500 | | 11:49 | chore: daily scan 2026-04-10 | 60 | +19,621 / -306 | | 13:08 | fix: server-side token gate for alpha endpoints | 6 | +87 / -10 | | 13:22 | feat: auto-update alpha history with daily picks | 3 | +499 / -20 | | 13:53 | fix: widen date matching for alpha grading | 2 | +75 / -36 |

What Didn't Happen

• No model retraining (day 16 — this is overdue)
• No newsletter system progress
• Brand book still blocked on Zen's stories
• No TESTED reviews published despite 36-item queue

Key stat: The alpha pick-of-the-day now has a real public track record — 26.3% ROI across 12 resolved bets at average odds of 2.64. That's the kind of verifiable edge that makes the $YOSHI token gate worth paying for.
