Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline
- Generate separated hydrogen by alkaline water electrolysis then dry and purify the gas
- Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.
What remains unresolved
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
- Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
- Electrodes, diaphragm/separation, purity, power and first gas media manufacture unresolved; electrolysis selected instead of AND-ing reforming feedstocks.
