Saved research and review
Paused earlier five-item batch: three authored drafts pending independent review, two remaining assigned items without completed reports.
Earlier interruption preserved. Author is now assigned comprehensive first-five research; this older batch remains paused rather than currently running.
Evidence review is separate from immediate-record completeness, current recipe qualification and manufacturing closure. Reports retain their original scope; later engineering changes require their own review.
Saved report scope revision 90 · independent review revision pending · current graph revision 138. Earlier claims about preserved inventories apply to their saved scope, not automatically to later enlarged selected routes.

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.

Inventory is a hypothesis; handling, waste, protection, calibration, quantities, losses and suitability are not completely identified.
Making outline
- Assemble selected pouch stack, weld tabs, seal/fill, wet, form under pressure, degas/reseal and verify cell
- Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.
What remains unresolved
- Bounded making-page evidence is saved; the complete immediate method, target specification, inventory and actual caller qualification still require comprehensive research and independent review.
- Candidate method, complete inventory, caller demands and physical compatibility require research and review.
- Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
- Electronics-owned formation-cycler has a selected discovery inventory for source/load/meters/cutoffs/controller/loading hardware; its physical suitability and first-making capability remain unqualified. No sealed cell is accepted before leakage, formation and safety/target tests.
Unselected discovery proposals
