# ── local weekly harvest — the no-GitHub-App autonomy path ──────────────────────
# Runs a headless Claude Code session (your subscription, your machine) through
# the /harvest skill. PROPOSE-ONLY BY CONSTRUCTION: this script creates the
# harvest/<date> branch BEFORE the agent starts and the agent never pushes —
# review with `git diff main...harvest/<date>`, merge with --ff-only when happy.
# Installed by tools/install-local-harvest.sh (launchd, Thu 09:00 local; launchd
# catches up after sleep — a closed laptop delays the run, never silently skips
# the week). Logs append to tools/harvest.log.

# Tier-1 deterministic health (consolidated 2026-07-16 — was a separate Monday cron):
# pulse (dead links/staleness/drift) + signals (recs vs live npm) + census (cohort
# adoption). Zero LLM; baseline updates land on this branch for review like everything
# else. Failures never block the harvest — the agent reads the logs either way.

PROMPT="Run the weekly react-brain harvest pass. Follow .claude/skills/harvest/SKILL.md EXACTLY — read it first, then tools/harvest-state.json and tools/upkeep-routine.md step 2. Tier-1 (pulse/signals/census) already ran — read the tails of tools/pulse.log, tools/signals.log and tools/census.log and fold dead links / drift / adoption deltas into the pass. You are ALREADY on branch $BRANCH: commit everything here, NEVER switch to or commit on main, NEVER push, never force anything. All gates must pass before your final commit (coverage, verify-diff --base=main, npm test); the advocate pass over your own skips is mandatory. This is a headless run: skip the maintainer-memory ledger steps — put the full narrative (issues processed, keeps with receipts, notable skips, counts before/after) in the final commit message instead. If there are no new issues AND no firsthand events, print a one-line summary and stop (an empty branch is fine)."
