From 68c9df354b03d82cb1f9891119edafbe3ea0b95c Mon Sep 17 00:00:00 2001 From: bastien Date: Thu, 24 Sep 2026 11:50:16 +0200 Subject: [PATCH] feat(gitflow): remove the origin copy of a branch once its merge is verified `gitflow_delete` now ends with `_gitflow_delete_remote`: after the local copy is gone, the remote tip is read with `ls-remote --exit-code`, checked against develop/main with the same ancestor test, and only then removed with `push origin --delete`. Same contract as the pushes (BDR-095): best effort, warn never fail. No origin, `GITFLOW_NO_PUSH=1` or `gitflow.autopush false` skip it; an unreachable origin or a remote tip holding commits the bases lack keeps the remote branch, loudly. A base is never targeted, by construction and by an explicit guard. The static deny on hand `git push --delete` stays: it matches the Bash tool's command string, the lib is the sanctioned path. Prose (hard_deny, environment), doctrine, gitflow SKILL (table, op, warning row), SETTINGS.md and CHANGELOG updated. T24: 9 checks (finish removes the copy, bases untouched, unmerged remote tip kept, never pushed silent, unreachable origin loud, autopush opt-out). 161/163, the 2 failures are the pre-existing T16a (gitleaks absent on this host). --- CHANGELOG.md | 5 +++- CLAUDE.global.md | 8 +++--- lib/gitflow-test.sh | 45 ++++++++++++++++++++++++++++++++++ lib/gitflow.sh | 43 ++++++++++++++++++++++++++++---- settings.json | 4 +-- skills/gitflow/SKILL.md | 13 ++++++---- templates/settings/SETTINGS.md | 4 ++- 7 files changed, 104 insertions(+), 18 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 276aa6e..aaad903 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -10,7 +10,10 @@ Format follows [Keep a Changelog](https://keepachangelog.com/). - **Branch deletion guard** — `gitflow_delete` (also `gitflow.sh delete `) is the only path that deletes a branch: it refuses `main` and `develop` (rc 6) and any branch not merged into develop or main (rc 5), - with an explicit ancestor check, and keeps the branch.
