+# Phase 29ad: Pattern6/7 naming SSOT (fixtures + smokes)
+
+Goal: remove ambiguous "firstfail" naming and make the variant explicit for every Pattern6/7 fixture and smoke.
+
+## Naming rules (SSOT)
+
+- Pattern6:
+  - `phase29ab_pattern6_<variant>_{ok|contract}_min.{hako,sh}`
+  - variants: `scan_with_init`, `reverse`, `matchscan`
+- Pattern7:
+  - `phase29ab_pattern7_splitscan_{ok|contract}_min.{hako,sh}`
+  - near-miss OK variant: `phase29ab_pattern7_splitscan_nearmiss_ok_min.{hako,sh}`
+
+## Current mapping
