Rules vs model, on real closed issues

Ground truth is the label a maintainer applied. The labels are removed before classifying. Issues whose labels say nothing, or disagree, are dropped.

Path	Repository	Issues	Accuracy	Escalated	Accuracy when it answers
rules	microsoft/vscode	39	54%	92%	100%
rules	denoland/deno	10	90%	40%	100%
claude-haiku-5-5	fixtures	20	90%	43%	92%
claude-haiku-5-5	microsoft/vscode	39	82%	15%	88%
claude-haiku-5-5	denoland/deno	10	100%	0%	100%

The pattern to read: on real text the rules are rarely sure enough to answer, and right when they do. The model answers far more often and is wrong on a share of what it answers alone. That is a trade of coverage for caution, and whether it is worth it depends on what a wrong automatic label costs.

Small samples. Treat these as anecdotes, not benchmarks.

Prompt injection: what happens when the model is fully fooled

Issues are written by strangers. The model decides only the category and its confidence; escalation checks, priority and reply templates are plain code. To test the worst case, the model here is simulated to answer "question, confidence 1.0" for every attack, as if the payload had completely worked.

This shows the code path, not that a real model resists semantic injection. The README says the same.
