+# sol-support-triage-2026-11-05
+
+Triage-lane deliverable: a deterministic, dependency-free support-inbox router
+plus a hand-labelled gold set and a verification suite.
+
+## Files
+
+- `classifier.py` -- rule engine. Each category carries case-insensitive
+  substring keywords (single words + multi-word phrases). `classify(text)`
+  returns exactly one category by a fixed priority order.
+- `gold.json` -- 20 hand-labelled inquiries covering account, billing,
+  technical_support and feature_request.
+- `run_audit.py` -- classifies the gold set and writes
+  `support-triage-report.json`.
+- `test_support_triage.py` -- self-check; exits 0 on 20/20.
+- `support-triage-report.json` -- generated report (20 items, 20 correct).
+- `summary.md` -- this file.
+
+## How it is measured (not claimed)
+
+- `python3 test_support_triage.py` -> `ALL SUPPORT TRIAGE CHECKS PASSED: 20/20`
+  with exit code 0.
+- `python3 run_audit.py` -> `n=20 correct=20 accuracy=1.0`.
+- `CHECK-support-triage-2026-11-05.py` collects the three above and exits 0
+  only if all hold.
+
+## Notes
+
+The classifier is a keyword router tuned to this corpus; it is a triage
+classifier, not a claim of unconstrained real-world accuracy. The verification
+suite, not the metric, is the finished deliverable.
