# Arco modules

## Purpose

This is the simple map of Arco modules: what is live, what exists but is still developing, and what is coming next.

Detailed behaviour belongs in each module's canonical operating file. Universal module rules belong in [arco-module-manual.md](https://drive.google.com/file/d/1X3uzbh2_7cu_ZJGCwpcLSVyWihXHQxgZ/view). Core functions and foundational subsystems that are not modules are intentionally omitted from this catalogue.

## Status definitions

**Live** — in active use as a working Arco module.

**Early** — exists and is usable, but its operating model is still developing. It may not be enabled in every deployment.

**Draft** — confirmed architecturally as an Arco module, but its canonical operating model and implementation have not yet been built or promoted.

**Candidate** — a possible future module whose boundary is not mature enough for canonical Core promotion.

## Live

### Skills
Repeatable maintained capabilities. Core: [arco-skills.md](https://drive.google.com/file/d/1k5LCI4ElPgVN4wpkMmc39T3YIEq8X6E1/view).

### Context
Durable personal and organisational context. Core: [arco-context.md](https://drive.google.com/file/d/1cHuOYhziNB8Iv1BMs-iP-5r4YEnS1XZp/view).

## Early

### Notes
Private personal working memory for unfinished observations, thoughts and follow-ups, with private-by-default storage and deliberate promotion into more authoritative owners. The core boundary and lifecycle are established; deployment-specific intake and setup remain evidence-led. Core: [arco-notes.md](https://drive.google.com/file/d/1SFSwTQRm3tFTMDw2zDr--agLW0kjBrw3/view).

### Personas
Reusable perspectives or modes of thinking. Its conceptual boundary has been proven through initial deployment use, while the wider operating model and deployment evidence remain early. Core: [arco-personas.md](https://drive.google.com/file/d/1J7UIPd1YVF9ve4Au7kQCP3uZA-UHOrlD/view).

## Draft

### Decisions
Durable organisational decision memory and lifecycle management. Decisions consumes Governance for Roles, Permissions and Approvals rather than redefining those mechanics.


## Candidates

### Policies
Maintained organisational policy knowledge and operating guidance.

### People Management
Emerging manager-oriented people understanding, development and longitudinal behavioural context built from verified evidence over time.

## Maintenance

Keep this file synchronized whenever a module is created, promoted, retired or changes maturity. It should remain a lightweight map rather than becoming an architecture manual.
