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
- Assemble moving-coil audio output and MEMS audio input with hardware codec/amplifier
- Characterize against caller requirements; quantitative process settings and tests remain unknown.
What remains unresolved
- Making route and target-level requirements not researched.
- Caller demands, compatible first production route, quantities, losses and acceptance not established.
