chore(repo): one-shot debris sweep

[julianken]

WHY

Drift audit 2026-05-04, nodes/11-repo-cruft.json findings 1, 4, 5, 6, 7. Local-state-only debris that should not pollute the working tree:

• .vercel/ directory — leftover from pre-pivot CLI usage; obsolete.
• 44 untracked PNG screenshots at repo root (gitignored, but still on disk).
• 6 local debris branches: pr-115, pr-115-final, pr-134-review, pr-142-bot-review, pr-142-head, pr-143-head.
• creative-output/blog-articles/ v1 (superseded by v2 per Julian's voice memory; v1 is no longer canon).
• .playwright-mcp/ files older than 30 days.

Important: this is not a PR. It is a documented runbook the issue captures verbatim; the issue closes when Julian confirms each step ran and reports exit codes.

WHAT

Runbook (paste-ready):

cd /Users/j/repos/tech-blog

# 1. Remove pre-pivot Vercel CLI residue
rm -rf .vercel/

# 2. Clean root PNG debris (gitignored, just clutters working tree)
rm -f *.png

# 3. Delete local debris branches
git branch -D pr-115 pr-115-final pr-134-review pr-142-bot-review pr-142-head pr-143-head

# 4. Remove superseded blog-articles v1 (creative-output is gitignored)
rm -rf creative-output/blog-articles/

# 5. Prune old Playwright MCP files
find .playwright-mcp/ -type f -mtime +30 -delete

DONE WHEN

• Julian comments the issue with the exit codes of all 5 commands.
• Issue is closed by Julian.

OUT OF SCOPE

• Any PR. Any code change. This is local-state hygiene only.
• Adding .vercel/ to .gitignore (already gitignored or trivially so; verify only if a PR is desired separately).

PRE-REQS

• chore(docs): purge docs/ to 4 files (delete 24) #240 must merge first so the docs/ purge is final and the working-tree state is clean.

Verdict: APPROVED.

Runbook is precise, scoped, verifiable, and the "this is NOT a PR" framing is explicit in the body. All five commands map 1:1 to audit findings 1, 4, 5, 6, 7. Pre-req on #240 (still OPEN) is sound — purging docs/ first means the working-tree baseline is final before debris removal.

Verification ledger (in this turn):

• .vercel/project.json exists, dated Feb 16 (pre-GCP-migration) — confirmed.
• 44 PNGs at repo root via ls *.png | wc -l — confirmed.
• All 6 local debris branches present, no upstream — confirmed.
• creative-output/blog-articles/ and -v2/ both exist — confirmed v1 is superseded per audit.
• 35 files in .playwright-mcp/ older than 30 days — confirmed.
• Title is 34 chars, under the 70-char cap.
• Pre-req chore(docs): purge docs/ to 4 files (delete 24) #240 state: OPEN. Sequencing matters; do not run this sweep until chore(docs): purge docs/ to 4 files (delete 24) #240 merges.

SUGGESTION (1, non-blocking): DONE WHEN says "exit codes of all 5 commands," but the runbook as written makes that easy to forget. Append ; echo "step N: $?" to each command (or wrap in a set +e; ...; rc=$?; echo "step N: $rc" block). Without it, Julian has to remember echo $? after each, and a forgotten capture means re-running to recover the code. Trivial change, makes the closing comment mechanical.

Optional nit, take or leave: rm -f *.png is unconditional. If a tracked PNG ever lands at repo root in future (asset, OG image), this command would delete it. Today all 44 are untracked, so it's safe right now. A safer one-liner: git ls-files --others --exclude-standard -z -- '*.png' | xargs -0 rm -f. Not worth changing for a one-shot runbook.

Bottom line: ship it after #240 merges. The two notes above are polish, not blockers.

Pre-req #240 merged at 63926ce. Local debris-sweep runbook is ready to execute. This issue stays OPEN as a runbook reference; close manually after running the commands listed in the body.
