Introduce scripts/project_rules/gitignore-claude.template with the fleet
pattern that tracks .claude/rules/ while ignoring machine-local Claude state.
ensure_gitignore_claude_rules.py applies it during statehub register,
register_project.sh, and update_agent_instruction_files fleet regen.
Infer workplan prefixes from on-disk filenames instead of first-token
derivation, add a frontmatter normalization script, and wire Make targets
for dirty-repo sweeps.
Introduce credential-routing.template for Codex, Claude Code, Grok, and
llm-connect agents. Wire into agents-codex.template and claude-md.template.
Add propagate_credential_routing.py for surgical rollout without clobbering
repo-specific AGENTS.md extensions (REPO-AGENTS-EXTENSIONS marker).
