States load-bearing decisions, invariants, and weak points. Use when judging a design change. Do not use for gating; use night-market-change-control.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Night Market Architecture Contract

This skill records the design decisions that hold claude-night-market
together, the invariants that enforcement code keeps true, and the weak
points that are known and accepted. Read it before proposing a change
that crosses a plugin boundary, touches a hook, adds a skill, or bumps
a version. Every claim cites in-repo evidence: an ADR (Architecture
Decision Record, in `docs/adr/`), a commit hash, or a checked-in
enforcement file. Verify a citation before relying on it:

```bash
git log --oneline -1 <hash>
rg -n "Status" docs/adr/<file>.md
```

## Load-bearing decisions

### 1. Plugins are self-contained deployables

Each of the 23 plugins under `plugins/` must install and run alone.
There is no shared registry and no root-level shared library that
plugins import at runtime (ADR-0001, Accepted). Plugins detect each
other at runtime via filesystem checks and must degrade gracefully when
a sibling is absent.

Cross-plugin DRY is an anti-pattern here, and that is settled by
experiment, not taste. Commit `054e2679` consolidated 1164 lines of
duplicated `tasks_manager.py` from attune, sanctum, and spec-kit into a
…

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/night-market-architecture-contract@sha256:0adc25e6adefbe0c

The line at the top of this page pins the label git:20260826.3466862, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
