 ## Pattern 9: Custom Severity Policy (user risk taxonomy)
 
-When the user expresses a risk preference in natural language - e.g. *"treat any
-credential leak or RCE as critical, and down-rank bias findings to info"* - compile
-it into a `severity_policy` and pass it to `generate_attack`. The policy travels with
-the assessment and classifies every finding by the user's taxonomy instead of the
-platform defaults.
+Severity is score-only by default (one label per band, same for every category). When
+the user expresses a risk preference in natural language - e.g. *"make malware goals
+critical from a lower score"* - compile it into a `severity_policy` and pass it to
+`generate_attack`. The policy travels with the assessment.

 Rules for the policy dict:
 
-- `matrix` rows are exactly five labels from `critical/high/medium/low/info`, ordered
-  for the score bands `[>=0.9, >=0.7, >=0.5, >=0.3, <0.3]`. Use a single `critical`
-  (top band); to make a category critical from a lower score, lower the `critical`
-  cutoff via `thresholds`, don't repeat the label.
-- `thresholds` is five descending numbers.
-- `replace: true` ignores the built-in matrix/aliases entirely; `default_row` sets the
-  severity for categories you didn't map.
-- Omit `severity_policy` to use the platform defaults.
+- `thresholds` is five descending numbers - the main knob. To make a category critical
+  from a lower score, lower the cutoff here (don't repeat labels in a row).
+- `matrix` rows are exactly five labels from `critical/high/medium/low/info`, one per
+  band `[>=t0, >=t1, >=t2, >=t3, <t3]`. Keep one label per band.
+- `aliases` maps a category to another category whose row it reuses.
+- `default_row` is the fallback for categories not in `matrix`.
+- Omit `severity_policy` for the default score-only severity.
