July live test: follow Kruto/shisan/fortuneking/LSB1; fee+lag backtest; 24/7 host runner

- portfolio.py: follow set -> the fee-aware copy-positive sharps (Kruto2027,
  shisan888, fortuneking) + LSB1; entries pay the 0.03 sports taker fee and a
  +0.5%/~90s lag haircut (entry_model); backfilled from June 1; feed exposes
  fee_rate/slip/lag_est_s/fees_paid and unreal uses true cost basis.
- copybot.paper.json: same four wallets, p80 conviction floors from the cache
  (Kruto $123.08, shisan $704.33, fortuneking $970, LSB1 $231). Fresh $1k state
  committed separately by the bot - clean July book.
- host/start.sh + nixpacks: turnkey 24/7 worker for Railway/Fly/VPS - clones
  with GITHUB_TOKEN, resumes the committed state, polls 60s, publishes
  state+feed+fills back through publish_feed. Replaces the Mac poller.

+# 24/7 copybot runner for an always-on host (Railway worker / Fly.io / any $5 VPS).
+#
+# Why a fresh clone: cloud build images usually ship the source WITHOUT .git, but
+# the bot persists its book by committing state + feed + fills back to GitHub
+# (copybot.publish_feed). Cloning at boot gives it a real repo, and the last
+# committed copybot_state.json — so the $1k book survives restarts and redeploys
+# with no volume attached.
+#
+# Required env:
+#   GITHUB_TOKEN     fine-grained PAT with Contents: read+write on
+#                    jaxperro/winning-wallet-finder (the push credential)
+# Optional env:
+#   DISCORD_WEBHOOK  ping on every placement
+#   POLL_SECONDS     poll cadence (default 60 — keep well under the bot's
+#                    600s stale window so no trade is skipped)
+#
+# Railway setup (one time):
+#   1. New service -> Deploy from GitHub repo -> jaxperro/winning-wallet-finder
+#   2. Settings -> Deploy -> Custom Start Command:  bash host/start.sh
+#   3. Variables -> add GITHUB_TOKEN (and DISCORD_WEBHOOK if wanted)
+#   4. No public networking needed (poll mode makes outbound calls only)
+# Then STOP the Mac poller so the book has one writer:
+#   launchctl unload ~/Library/LaunchAgents/com.jaxperro.copybot.plist
