Covers
Form handset rear cover from selected polymer; open discovery hypothesis, unknown caller demands and complete inventory.

Saved research and review
Bounded own-node research; physical completeness and acceptance not inferred.
Workers stopped after usage limit; user requested no process restarts while publishing shared project checkpoints. Saved evidence remains available; full research is not complete.
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.

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
- Retain provisional selected polymer molding with indirect fuel heat and circulating water-based die coolant; compatible solvent-clean mold/contacts then water rinse/dry is the single chosen provisional cleaning sequence.
- Preserve original five requirements and actual feed conditioning/protected transfer, sample/quantitative assay, gate/runner/vent/demold, actual fuel/coolant/cleaning/rinse and reject/runner quantities. No polymer family/grade/threshold is yet qualified.
- Mold, cool and demold the same advancing cover; capture actual trim/reject streams and accept geometry/attachment/chemical/seal/aging duty independently. Cabinet and grade-limited TVI remain separate unselected screening alternatives, not quantitative acceptance.
What remains unresolved
- Bounded making-page evidence is saved; a complete reviewed making method and qualified output are not established.
- Candidate method, complete inventory, caller demands and physical compatibility require research and review.
- Handset-interface geometry, compression/load, ingress/contact compatibility, creep/aging and accepted service life remain unfrozen/unqualified. Selected generic fiber-packing route does not establish this consumer duty; no different seal material is selected and generic seal construction stays unchanged.
- Feed conditioning method and quantitative assay technique are not selected; actual reagents/sample quantities and independent references remain open with analytical specialist ownership.
- Small-batch cabinet and grade-limited TVI are conditional alternatives only. No hotplate/slide screening apparatus is selected or assumed quantitatively adequate.
- Provisional selected coolant/cleaning sequence does not certify unknown polymer grade, moisture requirement, thermal capacity or solvent compatibility. Full material/grade/quantitative process research continues separately.
