test-iterate-loop
Autonomously diagnose a codebase, apply minimal fixes, and rerun tests until they pass or a real blocker is reached. Use when the user explicitly requests an iterative fix-until-green loop across Python, R, Julia, or HPC workflows.

# Test-Iterate Loop — Autonomous Bug Fix Cycle
> Autonomous loop: run tests → root-cause failures → apply minimal fix → retry. Bounded by iteration cap and same-error-repeat detector. Never commits — leaves clean working tree + markdown report. Generic across Python (pytest), R (testthat), Julia (Pkg.test), and HPC pipelines (mock-HPC Docker).
## Hard Rules
### Existential — block proceed
1. **Never `git commit`, `git push`, or modify `.git/` state.** All changes go into the working tree only. The user reviews the final clean tree + report and decides what to commit. Enforced via the standard forbid-list per `subagent-write-guard.md` if dispatching sub-agents.
2. **Bounded iteration: max 10 iterations OR 3-same-error-repeat — whichever first.** Hardcoded ceiling. Past that, stop and summarise. Don't ask "continue?" — exhaustion is the signal.
3. **Each iteration must change ≥1 file.** A no-op iteration (Claude couldn't propose a fix) counts as a same-error-repeat.
4. **Memory bug detector**: flag any iteration that adds a model load, env var change, or version pin without a corresponding test — these are common failure-cause patterns from past HPC sessions.
### Format — catch in review
