public grade
A
flagship triageraw 12/14 · raw 12–14 / 14
Awhat this grade means
real parser depth · 2+ exports with reason fields · honest limits · canonical UI shell
capability class · heuristic screener
rule-based scoring · statistical anomaly detection · gap analysis — flags worth checking, not verdicts
max grade for this class: B (A when honesty + output + UI all maxed)
- heuristic screeners flag leads, not verdicts — every hit needs corroboration
- threshold tuning affects false-positive and false-negative rates; uncommon baselines skew scores
- capability class H is capped at B unless honesty, output usefulness, and UI all score 2 and raw ≥ 12
known limitations
- even A-grade tools can be wrong on rare inputs, malformed files, or adversarial samples
- independent verification is required before consequential or evidentiary use
- the grade is not a court-admissibility score — jurisdiction and chain of custody still apply
B minimum ship bar
- newly added forensics tools must clear the public B minimum before merging
- minimum: letter grade B or A · raw score ≥ 9/14 · UI dimension = 2 · IF/OU/DQ/RB/HN ≥ 1 each · no critical red flags (missing engine, placeholder logic, no exports)
- the ship bar is enforced by quality.audit.json sidecars and npm run tools:grade-forensics --check
