2026-07-09	HW: cascade re-pricing under the reuse doctrine — depth becomes a memory ↵	Yuren Hao
	line-item (time-mux one trainable block), nudged duty drops ~50x, leash instrumentation deleted, SRAM-CIM alone suffices for Demo-1 (device fab optional) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-09	HW economics retraction: doctrine currency restored (COTS-stitch + FPGA + ↵	Yuren Hao
	UIUC collab, $5-20k Demo-1 BOM); optimizer state digital-side by design => Adam ~free, Muon unblocked at demo scale, choice is algorithmic Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-09	HW BoM correction: Lion/SGD ruled out for EP training (empirical, abl_lion2 ↵	Yuren Hao
	blew @600 + prior tests) — factored-Adam is the MANDATORY analog baseline, not premium tier Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-09	HW: optimizer BoM audit per cascade block — Adam analog-compatible via ↵	Yuren Hao
	factored-AGC (+2x memory, zero ADC), Muon priced out of analog (matrix-matrix NS + full-gradient ADC tax), Lion native baseline Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
2026-07-09	HW dossier: analog softmax/attention (12 verified claims) — Elfadel-Wyatt ↵	Yuren Hao
	1993 reciprocal 'entropic resistor' softmax (EP-composable, PAR escape realized), charge-domain KV gain-cells (Leroux 2025), the analog-training gap confirmed unclaimed; +-1% mismatch->+-1% softmax linear tolerance coeff Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014FAPDWQ49M5Ye3NpTndTpn
