+Resolve dataset audit (#365) and discontinued backlog (#362) findings.
+
+**Duplicate-name groups (#365):**
+
+- Merged true duplicates onto canonical manufacturer-slug filenames, keeping the
+  richer entry and pulling in `formats`/`categories` from the thin twin: 10 uJAM
+  Beatmaker instruments (`ujam-beatmaker-*` → `ujam-instruments-beatmaker-*`),
+  WA Production Babylon 2 and BassShaper (`w-a-production-*` → `wa-production-*`),
+  Airwindows Average (two blog-post imports of one plugin), and the DW
+  Satin-Black-over-Brass snare and 4-Piece Performance Series kit (duplicate SKU
+  codes).
+- Folded the three Taylor T5z Pro colorways (Cayenne Red, Harbor Blue, Tobacco
+  Sunburst) into one entry with a cosmetic `variants` array.
+- Renamed `fostex-t50rpmk4g-2` → `fostex-t50rpmk4g-plus` to match its product
+  name (T50RPmk4g+); it is a distinct SKU, not a duplicate.
+- Fixed the audit's `normalizeName` to treat a trailing `+` as a significant
+  `plus` token so distinct SKUs (ProFX10v3 vs ProFX10v3+, Prime 4 vs Prime 4+,
+  etc.) no longer false-collide. This clears ~12 false-positive groups whose
+  members were already correctly modeled as separate entries.
+
+**Discontinued backlog (#362):**
+
+- Auto-tagged 14 Tier-1 (superseded, missing `discontinued`) entries.
+- Reviewed and tagged 34 Tier-2 entries with explicit discontinuation language
+  (13 Audeze legacy headphones, 14 dbx Professional Audio units, Krotos and
+  Synchro Arts software, and others). Excluded `dubreq-ltd-stylophone-s2` — its
+  "discontinued in 1975" refers to the original Stylophone; the S2 is current.
