+## D-WS6a — Danish fine-tuned Whisper models: our own ONNX + CTranslate2 conversions, unpublished until the owner says go
+**Status:** Proposed (2026-10-29, spec 001 Goal 6)
+**Candidates checked (licence + architecture, from each repo's model card, config and notices):**
+- `thorhojhus/whisper-small-danish` — MIT; plain `WhisperForConditionalGeneration`, whisper-small
+  shapes and tokenizer unchanged (80 mel bins, 12/12 layers, vocab 51865). **Kept.**
+- `thorhojhus/whisper-large-v3-turbo-danish` — MIT; plain large-v3-turbo (128 mel, 32/4 layers,
+  vocab 51866). **Kept.**
+- `danish-foundation-models/edda-v0.2` — **Apache-2.0 confirmed** (licensor: the Alexandra
+  Institute; base model MIT); plain large-v3-turbo architecture, so Transformers.js loads it like the
+  stock turbo. Its `generation_config.json` pins `language: "da"`, `task: "transcribe"` and
+  `num_beams: 5`. **Kept.**
+**Catalog:** three entries with `verified: false` everywhere, ids built from one exported constant
+`DANISH_MODELS_HF_OWNER` (placeholder `"PENDING-OWNER"`): `<owner>/<name>-ONNX` for the browser
+engine and `<owner>/<name>-ct2-int8` as `fasterWhisperModel` (a Hub repo id — faster-whisper accepts
+those as well as its aliases). Publishing under the owner's account is a one-line change.
