-## Open Questions
+## Open Questions (RESOLVED)
 
-1. **Real NetBox API token**
-   - What we know: The `.env` file has a placeholder string `homelab-netbox-api-token-2024`
-   - What's unclear: The real token value; whether the current user account has admin permissions to create custom fields
-   - Recommendation: Wave 0 first task — generate real token via NetBox UI, update `.env`
+1. **Real NetBox API token** — RESOLVED: Integration tests use `t.Skip()` when placeholder token detected. Operator generates real token via NetBox UI before running provisioning (Plan 03).
 
-2. **netbox-inventory plugin installation (NB-03)**
-   - What we know: Plugin exists at github.com/ArnesSI/netbox-inventory; requires SSH to LXC 130
-   - What's unclear: Whether the LXC 130 has internet access for pip install, or if the plugin must be transferred manually
-   - Recommendation: Treat as a manual pre-phase step with a Makefile verification target
+2. **netbox-inventory plugin installation (NB-03)** — RESOLVED: Plan 03 implements runtime check via `/api/plugins/` endpoint with CLI warning if absent. Installation is a manual pre-requisite (SSH to LXC 130).
 
-3. **photo_urls field type**
-   - What we know: The requirement lists `photo_urls` as a custom field
-   - What's unclear: NetBox doesn't have a native array-of-URLs field type. Options: JSON field (store as JSON array string), multiline-text (one URL per line), or multiple object attachments
-   - Recommendation: Use `json` field type and store as a JSON array string; parse in Go
+3. **photo_urls field type** — RESOLVED: Plan 03 Task 1 uses `text` type with comma-separated URLs (simpler than JSON, sufficient for Phase 1).
 
-4. **PRD vs. REQUIREMENTS.md design system discrepancy**
-   - What we know: PRD says "Tokyo Night theme"; CONTEXT.md and PROJECT.md say "ClickHouse design system (pure black + neon volt)"
-   - Recommendation: CONTEXT.md wins — use ClickHouse design system. The stub Phase 1 frontend needs no real styling.
+4. **PRD vs. REQUIREMENTS.md design system discrepancy** — RESOLVED: CONTEXT.md and PROJECT.md specify ClickHouse design system. Plan 01 stub SPA uses ClickHouse colors.
