Coolant contact witness stock

Separate sacrificial samples of actual loop metals, glass and packing for water-coolant exposure, corrosion, leaching and aging comparison; no generic sample establishes caller acceptance.

Discovered · unresearchedClosure: OpenInventory incomplete

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

Cut separate actual candidate ferrous, copper, glass and cloth-packing contact specimens, retain untreated baselines and exposed/destructive allocations for caller-matched coolant comparison
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
