Problem

The manual developer-docs acceptance workflow verifies cleanly but WP Codebox correctly refuses publication because pnpm build adds eight untracked plugin outputs after the approved workspace snapshot.

Acceptance evidence: https://github.com/Automattic/build-with-wordpress/actions/runs/29643902298

Exact added paths reported by wp-codebox/runner-workspace-integrity-failure/v1:

• plugins/amp/AGENTS.md
• plugins/devin/AGENTS.md
• plugins/junie/.junie/AGENTS.md
• plugins/kilo-code/AGENTS.md
• plugins/opencode/AGENTS.md
• plugins/qodo/AGENTS.md
• plugins/roo-code/AGENTS.md
• plugins/zed/AGENTS.md

Root cause

scripts/build-plugins.mjs generates these files and scripts/verify-plugins.mjs requires them, while repository docs advertise them as package contents. They are not currently tracked. The configured drift check uses git diff, which does not report untracked files, but WP Codebox compares complete pre/post workspace snapshots and catches them.

Acceptance criteria

1. Track the eight canonical generated outputs.
2. pnpm build, pnpm verify, and producer contracts pass.
3. A clean build leaves no added, modified, or deleted workspace paths.
4. The manual PR-required developer-docs workflow reaches publication and opens the canonical documentation PR.
