run

<objective> Sustained metric-improvement loop — reads `program.md`, iterates specialist ideation agents, commits atomically, auto-rolls back on regression. For long-running automated improvement campaigns. NOT for: methodology validation before run (use `/research:judge`); hypothesis generation (use `research:scientist` agent); one-off feature work (use `/develop:feature`). </objective> <constants> Campaign mode only: ```yaml MAX_ITERATIONS: 50 (hard cap); DEFAULT 20 when max_iterations unset in program.md; program.md may raise up to 50; values above 50 clamped to 50 with a warning MAX_CODEX_RUNS: 10 (cost ceiling for --codex Phase 2c — disable Codex once exceeded) STUCK_THRESHOLD: 5 consecutive discards → escalation GUARD_REWORK_MAX: 2 attempts before revert VERIFY_TIMEOUT_SEC: 120 (local), 300 (--colab) COLAB_KNOWN_HW: H100, L4, T4, A100 SUMMARY_INTERVAL: 10 iterations DIMINISHING_RETURNS_WINDOW: 5 iterations < 0.5% each → warn user and suggest stopping STATE_DIR: .experiments/state/<run-id>/ (timestamped dir per run — see .claude/rules/artifact-lifecycle.md) SENTINEL_SLUG_FORMULA: | eval "$(bash "${CLAUDE_PLUGIN_ROOT:-plugins/cc_research}/bin/git_slugs.sh")" # Sentinel path: ${TMPDIR:-/tmp}/claude-commit-auth-${REPO_SLUG}-${BRANCH_SLUG} # tmpdir-exempt: user-shell-boundary # Bash state is lost between tool calls — re-source git_slugs.sh at each use site; it is the only...
