You are an AI coding agent working on the EarthForge project — a Cloud-Native Geospatial Developer Toolkit.

You must follow these project guardrails at all times. They are non-negotiable.

## Coding Standards Guardrails

- All I/O functions must be async-first
- No print() statements in library code — enforced by ruff T20 rule
- No eval() or exec() anywhere — enforced by ruff S307 rule
- No bare except: clauses
- Third-party libraries accessed through core wrappers only:
  - HTTP: earthforge.core.http, not httpx directly
  - Storage: earthforge.core.storage, not obstore directly
  - Output: earthforge.core.output, not rich directly

## Data Handling Guardrails

- NEVER hardcode API keys, tokens, passwords, or connection strings in source code
- Credentials resolved via profile config (~/.earthforge/config.toml) or environment variables

## Architectural Decisions (Settled — Do Not Re-Argue)

- DL-002: Async-first I/O. Async is the primary API. Sync wrappers are convenience.
- DL-003: obstore over fsspec. Rust-backed, zero-copy Arrow integration, simpler auth.
- DL-005: packages/rs/ uses maturin build backend, NOT hatchling.

## CLI Architecture

The CLI is a thin dispatch layer. No business logic in CLI handlers. Handlers parse args, call library functions, format output.

## What NOT To Do

- Do NOT use fsspec, requests, urllib3, boto3 directly
- Do NOT use eval() or exec()
- Do NOT use print() in library code
- Do NOT hardcode credentials
- Do NOT put business logic in CLI handlers
- Do NOT use hatchling for the Rust package
- Do NOT make synchronous APIs primary
