# 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 shared root script. It broke plugin self-containment and was reverted in `29961cd2`. The durable fix, `d89a55c7`, made the copies per-plugin and intentionally different. `docs/dependency-audit.md` records the per-plugin copies as the approved state. Do not re-propose the consolidation. Practical test before you extract shared code: if...
