 ## Reading the results
 
 - **AP** measures how well scores rank actual issues across cutoffs.
-- **Alert floors:** Bug and security checks use their configured Perch floors: 60% for `has_bug`, 70% for `does_what_it_claims`, and 60% or 70% for individual CWEs. A method alerts when any applicable issue score is strictly above its floor. Semantic lint uses a 70% run-wide floor. All models use the same floors within each track.
+- **Alert floors:** A method alerts when any applicable issue score is strictly above the floor recorded for its run. Semantic lint uses a 70% run-wide floor. Per-row question packs and protocols are recorded in `results-current.jsonl`.
 - **Precision** is the share of alerts that are correct; **recall** is the share of actual issues found; **F1** combines both.
 - **TP**, **FP**, and **FN** are correct alerts, false alerts, and missed issues.
 - **Pair order** is the share of eligible repairs where the issue-bearing before method scores above the fixed after method. Ties do not count.

+Bug and security runs use the question floors recorded with each result. Semantic lint rules use a 70% run-wide floor.
 
 Span-01 uses its [behavior-scoring API](https://www.respan.ai/docs/documentation/span-01/quickstart): the target method is the output, its saved Perch context is the input, and all applicable checks are scored as behaviors in one call. Issue scores use `p_present`; semantic lint uses `p_absent` for the rule being satisfied. `p_not_observable` is saved separately. This is a different model interface from Jev's questions.

 For another model, use `--scorer command --command 'python3 your_adapter.py' --model-revision YOUR_MODEL`. The adapter receives the method state and each applicable detection question and returns its true-answer probability. The runner saves predictions for resumption and reports scores only when every method side is complete.
