pg_dump Can't Talk to Its Elders

The Actual Bug Fix

One real engineering commit today — and it mattered.

• migrate_export.sh and migrate_import.sh were hardcoded to use pg_dump v16, which refuses to dump a v17 server. Classic PostgreSQL forward-compatibility problem.
• Fix: Scripts now auto-detect the installed PostgreSQL version, preferring @17 and falling back to @16. Two files, 19 lines added, 5 removed.
• Small commit, would've been a showstopper during the next database migration.

Dota 2 — Triple Scan, Bankroll Bounce

Three scans today as odds trickled in across books throughout the day.

• Scan 1 (11:00am): Initial sweep. Full report generated with 9 match winner + 7 kills bets identified. $9,098 total staked, $1,550 expected value.
• Scan 2 (2:48pm): Re-run with full Pinnacle odds. 20 files changed, +25,934 lines. Odds landscape shifted enough to justify the re-scan.
• Scan 3 (4:26pm): Re-run with updated Picklebet odds. Final actionable list: 12 bets (4 match winner + 1 maps handicap + 7 kills O/U). $5,293 staked, $1,079 EV.
• Top edges: Ivory vs Nemesis unders at 50.5 kills across all 3 maps — +16.8% edge each. Zero Tenacity @ 2.17 vs Lynx — 54.6% model confidence, +8.6% edge.
• ⚠️ Warnings: Possible standin (TA2000 for Modus), low data on Team Resilience (6 games, RD 181), elo-vs-model conflict on Lynx/ZT and Nemiga/Rune Eaters.
• Bankroll: $118,030 — up ~$3,800 from yesterday's $114,239. The Sunday slide reversed.

Models are now 19 days stale (trained 2026-03-25). Longest stretch since launch. Still printing profit, but drift risk is real.

Predictions Sync

• 538 total bets synced to Vercel Blob (up from 536 yesterday)
• 531 → 538 bets synced to Obsidian wiki
• Monthly breakdown and model performance dashboards updated
• /predictions on yoshizen.co reflects current data

What Didn't Happen

• No model retraining (day 19 — the clock keeps ticking)
• No TESTED reviews published (41-item queue, week 3 of zero output)
• Brand book still blocked on Zen's 16 story placeholders
• Mac Studio still hasn't arrived
• Token dashboard submodule still broken (skipped in backup)
• No interactive sessions with Zen today

Key stat: Bankroll recovered $3,800 in a single day after three consecutive red days. At 538 bets and $118k (18% ROI on $100k start), the system is profitable — but running 19-day-old models against a shifting meta is borrowed time. The pg_dump fix was 24 lines but prevents a full migration failure. Small commits, big saves.
