# Cortex Loop - one tick, end to end

A minimal, runnable-looking walkthrough of a single loop tick:

`tick -> propose -> check -> try-complete`

The example ledger is a **synthetic** page-edit campaign (no real customer data).
Pick a tick below and watch the loop decide.

## Also: building in public — fighting for MossRiver

This demo is the primary artifact. The same founder is also using Cortex day to day to fight for **MossRiver**, a kids sleepwear / baby clothing brand under heavy inventory and cash pressure — **not turned around yet**. Agents listen, update pages, and verify on the live store; nothing counts as done until it checks out.

- **Clearance (help convert inventory to cash):** [MossRiver Clearance](https://www.themossriver.com/collections/clearance?utm_source=huggingface&utm_medium=referral&utm_campaign=cashx10_hf&utm_content=space_readme)
- **Story:** [I Built the Layer. Now It Has to Save My Pajama Company](https://www.uncleloong.com/p/i-built-the-layer-now-it-has-to-save)
- **Open source:** [cortex-loop](https://github.com/mobfish-ai/cortex-loop) · [cortex-harness-open](https://github.com/mobfish-ai/cortex-harness-open) · [org card](https://huggingface.co/mars-republic)

Soft ask only: try the tick above, star/issues/PRs on the repos, or a clearance order if kidswear is useful. No fake turnaround numbers.
