Cover glass
Cut, edge-finish and chemically strengthen sodium aluminosilicate sheet; open discovery hypothesis, unknown caller demands and complete inventory.
Current research paused · earlier saved evidence available · earlier evidence draft reviewedClosure: OpenInventory incomplete
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
- Select provisional wet-abrasive sizing/edge finishing, water rinse/dry and salt strengthening; score-break/dry finishing remain separate unselected methods.
- Prepare untreated lot/control inputs first, allocate real cutting/edge compound/water/clean transfer, then expose actual witness/production samples in the constructed bath with actual fuel/salt/reference duty.
- After the job, separate treated and hold-out control specimen outputs for actual stress/strength/edge tests; retained later tester samples/coupling medium/tip replacement do not pre-exist their producing treatment.
- Preserve every original nine requirement and all current independent specialized acceptance/stock/handling/waste obligations; actual glass/abrasive/salt grade, geometry and quantified demand remain unqualified.
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.
- No cutting method, glass/salt recipe, test threshold or numeric target selected. Specialist stress/strength identities are now canonical discovery hypotheses; their actual-glass measurement/reference suitability remains unqualified.
- Coupling optics/liquid, actual glass constants, full-profile/interior-tension range, edge impact force/velocity/contact and four-point-bend references remain specialist qualification duties.
- Future frontier warning resolved at bath prerequisite allocation: first bath consumes earlier untreated witnesses. Later strengthened/control specimens still require explicit actual sheet/preparation/treatment history when their own route is discovered; no accepted cover-glass prerequisite.
