 "title": "Stop PSSA training when the loss blows up",
 "page_title": "How to stop PSSA training when the loss blows up with Pssa",
 "summary": "Use the loss guard flags to abort a run before a bad loss overwrites a good checkpoint.",
 "who": "A researcher running an unattended training job who wants to avoid losing a good checkpoint to a loss spike.",
 "problem": "A loss blow-up can silently replace a good checkpoint with a broken one during a long unattended run.",
 "outcome": "A training run that aborts after three consecutive suspect loss groups without writing or replacing a checkpoint, plus a halt reason in the monitor.",
 "steps": [
  "Build the Pssa binary from the repository. (inferred, check the README)",
  "Run `pssa train corpus.txt --loss-guard-high-factor 4 --loss-guard-jump-factor 8 --loss-guard-patience 3` to start training with explicit guard settings.",
  "If you resume a run, repeat the same custom guard values on the resume command, since they are runtime only.",
  "Open `pssa tui` to see the configured guard and any halt reason in the monitor.",
  "Keep the last good checkpoint and compare any new checkpoint before using it."
 ],
 "agent_prompt": "In the Sparticle62ops/pssa repository, run `pssa train <corpus-path> --loss-guard-high-factor 4 --loss-guard-jump-factor 8 --loss-guard-patience 3`. Report whether the run finished or halted, and the halt reason if it halted. Verify that no checkpoint was replaced after a halt.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The README says this is not a held-out validation monitor and a resumed run starts a fresh loss history, so the guard does not measure generalization.",
 "category": "Research",
 "tags": [
  "Research"
 ],
 "lang": "rust",
 "requirements": [
  "A Rust toolchain (inferred from the Rust implementation and the cargo commands in the README)",
  "The pssa binary built from the Sparticle62ops/pssa repository",
  "A plain UTF-8 text file to train on",
  "A terminal that supports the TUI, or use --no-tui for plain logs"
