feat(mother): cost dashboard — human gallery + agent JSON with screenshot proof
Three new files in packaging/mother/dashboard/:
index.html (460 lines) — Self-contained cost dashboard:
- Cost cards with cache-hit bars (green cache / grey fresh)
- Node-grouped rows with summary stats (task count, cost, success rate)
- ▸ proof badge on cards with linked tmux-screenshot PNGs
- Lightbox viewer for terminal screenshots at task completion time
- JSON toggle for agent-friendly structured data
- Filters: node, provider, success/failure
- Dark terminal theme, monospace, responsive
- Auto-refresh every 60s
export-costs.sh (75 lines) — PostgreSQL → JSON export:
- Denormalizes task_costs + hive_nodes into dashboard data file
- Computes summary (total cost, avg, success rate, cache-hit ratio)
- Groups by node with per-node stats
- Limits to 200 most recent tasks
deploy.sh (45 lines) — Idempotent mother deploy:
- Copies dashboard files to /usr/local/www/clawdie/dashboard/
- Installs cron job (every 60s)
- Runs initial export
Schema:
- task_costs.screenshot_uuid column (TEXT, nullable)
- report-task-cost SSH command updated: node_hostname→node_id lookup,
screenshot_uuid field, NULLIF for empty strings
Wiki:
- cost-dashboard.md — architecture, data sources, deploy flow,
agent-friendly JSON format, screenshot proof design
- Index updated (EN)
184 wiki refs, clean lint, cargo fmt pass.
