# Checkpoint indicator catalog

**Status:** v0.1 (minimal, for setup runs). ASSEMBLY-WP-0010-T01 extends it to
full sensor bundles for all stocks (`metrics/MetricsCatalog.md`).

Jurisdictions: **US**, **EU** (with Germany where available), **Argentina**
(the owner's hypotheses: the EU lags, Argentina may thrive). Add others only
with a reason.

Mapping caveat: these indicators are *proxies*. None of them equals the model
quantity. Band positions are judged from several proxies together, never from
one.

## Light checkpoint: adoption, investment, sentiment, legislation

| # | Indicator | Jurisdiction | Primary source | Model quantity (proxy for) |

| L2 | Share of enterprises using AI technologies | EU, DE | Eurostat, ICT usage in enterprises (AI module) | K_Ω adoption breadth |
| L3 | AI use by firms or workers | AR | INDEC / national ICT surveys, or OECD / IDB regional data | K_Ω adoption breadth |
| L4 | Share of tasks or conversations by occupation; automation vs. augmentation | global, per country where published | Anthropic Economic Index; comparable usage indices | K_Ω task share, automation share |
| L5 | AI-related investment (data-center capex, information-processing equipment) as share of GDP or of GDP growth | US, EU | BEA; Fed / central bank notes; company capex guidance | organism investment `aO` |
