Update Spot Bundle

Fills the gap between the committed year JSON files and today's sqld data, then rebuilds data/spot-history-bundle.js — the offline fallback for file:// protocol where the app can't reach the API.

Replaces: seed-sync (retired — was repackaging stale static JSON files, never fetched live data)

---

When to Run

• Before every release PR (gate in CLAUDE.md Pre-flight)
• Any time you want to pull fresh spot history into the bundle

Prerequisites

SQLD_URL must be set and Tailscale must be connected:

export SQLD_URL=http://192.168.1.81:8080
# SQLD_AUTH_TOKEN is optional — local sqld runs without auth

Execution

SQLD_URL=http://192.168.1.81:8080 python3 .claude/skills/update-spot-bundle/update-spot-bundle.py

Run from the project root (script resolves paths relative to itself).

What It Does

1. Scans data/spot-history-{year}.json files to find the most recent date
2. Queries sqld for all spot prices after that date (fills the gap)
3. Appends new rows to the current year's JSON file (source: "sqld")
4. Rebuilds data/spot-history-bundle.js from all year JSON files

Both the bundle (offline use) and the year JSON files (fetchYearFile() in HTTP mode) stay current.

Verification

After running, output should show:

• Found N new day×metal entries from sqld
• Coverage: 1968 → <today>
• Bundle size 750 KB+

Then stage: git add data/spot-history-bundle.js data/spot-history-*.json
