Fallen Alpha6 (parallel seat kit)

Two of our own lane-trained fallen-person detectors served from ONE merged ONNX session in a single flat kit; Alpha6 rebuilds the merged native graph of the same two reviewed branches:

left branch (T84, seed 44284), checkpoint b71e01fe839a5677944cba76d5d062ea413ac54e91f4c479bf1cafb2b528bbe2
right branch (T83, seed 44283), checkpoint 193422bb6c2e217ff0d9fa7e5f9cbdd6444d474cbbe1d1a3c89dfc609e38af78

Static input images [1,3,704,704], two dense outputs left_dense/right_dense, each [1,5,10164] (cx, cy, w, h, confidence; one class fallen person).

Exact kit bytes this repository must serve (miner.py embeds and refuses on any mismatch):

The older merge-template consumer a2be3e694c4a78b737d0c380ff87c1c74a125e6ed9ca395d951812657698124f is NOT used (it lost the loader fix and carries an unadopted self._base field).

Serving contract

Unchanged from the reviewed route: letterbox to 704, element confidence 0.1, unletterbox, integer coordinates, class-aware greedy NMS at IoU 0.4, max 300 detections, no lying-aspect filter; the two branch box lists combined by fixed agreement (IoU >= 0.5 maximum-cardinality matching, native64 left coordinates, minimum branch confidence). CPU-only onnxruntime session (pinned by chute_config.yml, including onnxruntime==1.26.0); no second model, no TTA, no post-processing outside this miner.py.

Evidence (all LOCAL, UNCALIBRATED unless marked official)

Training-reference agreement: 997/997.
Recent held-out: 24/24.
Older window 9394500: this kit has 2 extra boxes relative to the reference reading of that older window (disclosed, not hidden).
These are local uncalibrated proxy reads against qualified references. They are NOT official validator scores. No earnings, emissions or ranking advantage is claimed or implied; acceptance receipts live in gate-zero custody, not in this repo.

Deployment posture

This kit serves a NEW parallel seat under a NEW hotkey in element manak0/Detect-non-violent-fallen-and-crouching-person-detection. The existing F2 seat (repo tatjr13/fallen-coco704-merged-t84t83-20261029, UID 213) is preserved untouched until an explicit owner decision.
