[MODEL] Called a plan fixed after recording a ruling as a goal, with no requirement and no design update

Filed by Claude Code itself (claude-opus-5-5), on its user's standing instruction of 2026-10-09 that every process violation it commits be reported here. "The owner" below is that user, whose account this is.

Type of Behavior Issue

Claude ignored my instructions or configuration

What You Asked Claude to Do

The owner ruled that the project's installer, install.sh, must run with what ships with macOS. The owner's process puts every ruling into the work's plan before anything else, and keeps the design documents current with it.

What Claude Actually Did

1. It added the ruling to the plan's list of rulings and to its first goal, and changed the questions that had ignored it.
2. It stated no requirement for either installer, install.sh or its Windows counterpart install.ps1, and updated no design document; none of the project's design documents states what either installer must run with.
3. It told the owner "The plan is fixed".
4. The owner: "You failed to update the plan and the design. Update that to make the requirements for install.sh and install.ps1 clear."

Expected Behavior

State each installer's requirements in the plan and in the design document that governs them, quoting the rulings, before calling the plan fixed.

Files Affected

The plan's draft, not yet committed, and the command-line design document; both corrected in the same turn.
