Main board
Populate patterned board with selected active chips/passives and verify joints/interconnect; open discovery hypothesis, unknown caller demands and complete inventory.

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.

Making outline
- Populate patterned board with selected active chips/passives and verify joints/interconnect
- Research detailed preparation, operation and acceptance. Numerical limits and suitability are not specified.
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.
