You are helping me build the following AI agent workflow.

## Goal
INSEE Company Data Enrichment for Agile CRM: Syncs Agile CRM companies with French INSEE OpenData to add SIREN IDs and addresses without overwriting existing info.

## Specification
- What it does: Get accurate French addresses and SIREN IDs for your Agile CRM companies by syncing with INSEE OpenData without losing existing information. This automation enriches your profiles using government data while keeping a read-only mode to protect current records from accidental overwrites.
- Trigger: Run manually (Manual · on demand)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Agile CRM: Source and destination for company records
  - INSEE OpenData: External database for French company address and SIREN lookup
  - Code: Logic to handle readonly checks and data mapping

## Known pitfalls, handle each one explicitly in your implementation
1. INSEE API responses can be inconsistent with address formatting so you must parse the nested JSON structure carefully to avoid null reference errors.
2. Company names in Agile CRM may differ slightly from official INSEE records so implement fuzzy matching logic rather than relying on exact string equality.
3. Accidental overwrites can corrupt existing customer data so always enable the read-only mode by default during initial testing phases.

## Reference implementation
https://n8n.io/workflows/2633 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
