Add v79 (SM8750 / Hexagon v79) bundle
Adds a v79/ bundle (Hexagon v79 / SM8750, Galaxy S25, soc_model 69) alongside the existing arch dirs. Compiled with QAIRT 2.48. Nothing under v75/ or v81/ is touched.
Device validation — SM8750 / v79
⚠️ NOT accuracy-gated. Matches the HF fp32 oracle exactly on only 3 of 6 images (mean character similarity 0.876).
Run on a real Galaxy S25 via QHexRT Plane A (qhx_asr / qhx_embed / qhx_generate). Full record, build recipe and gotchas: forge/recipes/nvidia/*/results/device_v79.json.
Why this one is not gated
It runs, and on 3 of 6 images it reproduces the HF oracle exactly. On the rest it repeats a sentence, drops a leading word, and misreads 11 as 1.eq in a table. Worth knowing before anyone chases it: the missing-leading-word symptom is not a port defect — the HF fp32 oracle drops exactly the same words on the same pixels. The test images were synthetic renders, which are out-of-distribution for a document parser; a definitive gate needs real document scans with published ground truth. Review accordingly before merging.
Gate B (raw-I/O parity) has not been run for this model on this arch; the accuracy evidence above is end-to-end plus the offline export gates.
