Dirty-main narrow fix promotion with stash recovery

Use when:

• a single verified fix commit must be promoted to main
• /mnt/local-analysis/workspace-hub main is dirty
• you also need to create GitHub issues from generated scripts without trusting assumed labels

Core lessons

1. Do not cherry-pick onto dirty main.
2. Before gh issue create, verify exact repo labels; do not assume generic labels like tests, parsing, or releases exist.
3. git stash push -u may be the right move for a quick narrow promotion, but stash apply can fail after the cherry-pick/push if the restored work overlaps files changed by ongoing local work.
4. If restore fails, keep the stash; do not drop it. Prefer recovery in isolation rather than forcing restore on dirty main.

Issue-creation preflight

Run before creating issues:

gh auth status
gh label list --repo <owner/repo>
gh issue list --repo <owner/repo> --state all --search '"<exact proposed title>"' --limit 10

Rules:

• use only labels that actually exist in the target repo
• exact-title search is cheap and catches obvious duplicates
• if a label is missing, patch the local issue-generation scripts before creation

Narrow promotion flow from dirty main

1. Inspect dirty state:

cd /mnt/local-analysis/workspace-hub
git status --short --branch

2. Stash tracked + untracked state:

git stash push -u -m "pre-<commit>-promotion-YYYY-MM-DD"

3. Verify clean enough to proceed:

git status --short --branch
git stash list | head

4. Update main and verify fix absent:

git fetch origin --prune
git pull --ff-only origin main
if git merge-base --is-ancestor <commit> HEAD; then echo already-present; else echo absent; fi

5. Cherry-pick and validate:

git cherry-pick <commit>
bash tests/hooks/test-require-plan-approval.sh
git push origin main

6. Restore the stash conservatively:

git stash apply stash^{/pre-<commit>-promotion-YYYY-MM-DD}

Use apply, not pop, so the stash survives failed or partial restore.

If stash apply fails

Symptoms:

• Your local changes to the following files would be overwritten by merge
• promotion already succeeded and pushed

Response:

1. stop immediately
2. confirm the promoted fix is on main and pushed
3. confirm the stash still exists with git stash list
4. do not drop the stash
5. do not continue unrelated work from this dirty main
6. recover in isolation:
   • preferred: create a recovery branch/worktree from the stash and inspect/merge deliberately
   • avoid repeatedly stacking more stash/apply operations on dirty main

Why this matters

This pattern preserves the narrow promotion audit trail while protecting the original dirty local state. It also avoids GH issue creation failures caused by repo-taxonomy drift between assumed labels and real labels.

Verification checklist

• gh auth status healthy
• exact labels verified in target repo
• duplicate-title search returns no exact matches
• fix commit not already on main
• targeted regression test passes after cherry-pick
• push succeeds
• if restore fails, stash still exists and is preserved for isolated recovery
