Run against TirSystem-BashScript/RepoFoundry (39 shell files): shellcheck passes with the project's .shellcheckrc, shfmt fails on 10 files only because of the case indentation and passes after one .editorconfig line; the pull request itself passes. Record the findings for the guide, review the change (RC-039) and update TM-001. The adoption is complete when RepoFoundry PR 76 is merged. Task: MIL-003#4
