[v1] - 2026-04-28

Initial cookbook published the day of the Polymarket V1 → V2 cutover.
Working code: examples/before-v1.py, examples/after-v2.py, examples/diff.md.
Hour-by-hour docs/timeline.md of the cutover (11:00 UTC – 17:00 UTC).
docs/allowances.md — V1 vs V2 contract addresses and the only working wallet-migration method (manual UI trade ≥5 shares).
docs/cancel-only.md — detection, retry-storm avoidance, when it lifts.
docs/troubleshooting.md — 12 specific errors I personally hit + the exact fix for each.
tests/test_v2_imports.py — smoke test verifying V2 SDK is installed AND wallet has V2 contract allowances.

This cookbook is documentation-only — no PyPI distribution.
Author: solo operator running polymarket-crash-bot (308 closed trades, 80.2% WR).
Bot was migrated live during the April 28, 2026 cutover. Total wall time: ~4 hours.
