CLAUDE.md claudeA

This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.

CLAUDE.md is agent-read markdown (claude) from lucasuiii/modeling-workbench.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# CLAUDE.md

Choose the entry point from the user's task:

- **Solve or resume a contest problem:** read [.agents/skills/cumcm-workflow/SKILL.md](.agents/skills/cumcm-workflow/SKILL.md) and follow it. The engineering instructions below do not apply to solving the contest problem. Resolve this link from the directory containing this file, not the contest workspace.
- **Edit this workflow repository:** follow the engineering instructions below. Do not start a contest run unless requested.

The Claude Code Skill at `.claude/skills/cumcm-workflow/SKILL.md` routes to the same canonical workflow.

## Layout

`.agents/skills/cumcm-workflow/` is the single canonical tree: `SKILL.md`, `references/`, `schemas/`, `scripts/`, `assets/`. `.claude/skills/cumcm-workflow/SKILL.md` is a thin router into it and deliberately restates no rules — if you add a rule, it goes in the canonical tree only.

## Invariants to preserve when editing

- **Machine facts are recorded, never hand-written.** If a change would make an agent type a SHA-256, an exit code, a page count or a result value into a contract, the change is wrong; extend a recorder instead.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
