Keep private execution records out of the public tree

Ralph run state, the Codex RC work plan, and the superseded progress snapshot are now local-only artifacts. Exact ignore rules prevent agents from accidentally publishing them again while git rm --cached preserves each local copy.

Constraint: Removing files from the current tree does not erase their content from existing Git history

Rejected: Add archive banners to the tracked files | that keeps internal execution records public and lets stale plans continue to look repository-authoritative

Rejected: Use .git/info/exclude | local-only rules would not protect other clones or contributors

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Do not re-add local agent plans or progress logs without an explicit maintainer decision

Tested: git diff --cached --check; exact git check-ignore matches; local files retained; files absent from git ls-files

Not-tested: Git history rewrite, intentionally out of scope
