• 🔴 (11:33) User stated that if the 'closed' pull_request event is missing, previews never clean up and gh-pages bloats until hitting GitHub Pages limits.
• 🔴 (11:33) User stated requirement: workflows must never run for fork PRs which lack write access.
• 🔴 (11:33) User stated requirement: gh-pages must never bloat past GitHub Pages' build limits again.
• 🔴 (11:33) User stated requirement: cleanup process must never download large preview artifacts (use blobless/no-checkout clone).
• 🔴 (11:33) User stated requirement: cleanup logic must never delete a live preview.
• 🟡 (11:33) Context: Running jj failed with "There is no jj repo in '.'"; repo at /home/byk/Code/getsentry/cli is currently a Git repo requiring jj git init to use jj.
• 🟡 (11:33) Context: Git status shows branch main behind origin/main by 16 commits with modified file .lore.md and multiple remotes (origin, elucid, raees).
• 🟡 (11:33) Context: Multiple local worktrees exist under ~/.local/share/opencode/worktree/... with branches including chore/preshape-monorepo, byk/fix/alias-common-prefix-strip, byk/refactor/debug-files-shared-walker.
• 🟡 (11:33) Context: Additional worktrees under /home/byk/Code/getsentry/cli-wt/ and /tmp/opencode/ with branches like byk/fix/agent-skills-atomic-write, byk/feat/snapshots-upload, chore/bump-binpatch-031 (prunable), byk/fix/delta-apply-progress-pct-only.
• 🟡 (11:33) Context: GitHub Actions workflow "Docs Preview" includes gating logic if { [ "$build" = "true" ] || [ "$ACTION" = "closed" ]; } && [ "$IS_FORK" != "true" ]; to allow builds or cleanup only for non-fork PRs.
• 🟡 (11:33) Context: Workflow uses dorny/paths-filter@v4, runs on ubuntu-latest, builds docs in apps/cli-docs, injects debug IDs, uploads sourcemaps, and pushes to gh-pages.
• 🟡 (11:33) Context: Cleanup job uses blobless, no-checkout clone strategy to avoid downloading large previews and iterates pr-<number> directories, removing only non-live previews.
