Named evidence gapDoes drip rate or transfer duration change post-arrival outcomes?
A precise unanswered question is part of the source of truth. It prevents an absent study, indirect result or popular rule from becoming false certainty.
This is a current search boundary, not proof that no study exists. The dated searches below show what was checked, which candidates were included or excluded and what evidence would change the answer.
Current boundary
No direct Neocaridina comparison was located for drops per second, transfer duration or TDS-gap formulas.
What would answer it
Replicated transport and receiving-water comparisons with bag chemistry, matched transfer treatments and survival through delayed follow-up.
Answerability brief
A coordinated community study may answer part of it
A prospective shared protocol across independent systems may answer a bounded field question if allocation, denominators, exclusions and analysis are fixed before outcomes are known.
Decision at stake: Whether a defined transfer method improves delayed post-arrival outcomes for a measured package-to-receiving-water difference.
Primary endpoint: Survival and condition through delayed follow-up, with immediate behavior kept as a secondary endpoint.
Minimum design: Prospective matched shipments or simulated transport units assigned to clearly defined transfer methods, with package chemistry measured at opening and receiving water standardized.
Required reporting: Animal source, package unit, density, transit history, opening temperature, pH, ammonia and conductivity, receiving water, exact transfer trajectory, allocation, package-level denominators, delayed deaths and exclusions.
Community can contribute: A shared protocol across independent shipments can contribute if the package is the unit, methods are assigned prospectively and delayed outcomes include every animal.
Community observations cannot establish: Self-selected acclimation stories without package chemistry, comparison or delayed denominators cannot identify an ideal rate or duration.
Closure rule: The answer remains conditional on package chemistry and receiving-water contrast; no one clock time may be generalized beyond the tested protocol.

Current research allocation
Design before asking people to participate
Method, units, exclusions, welfare boundaries and analysis must be frozen before inviting participation or viewing outcomes.
Why this allocation: The question is common and could change receiving practice, but self-selected acclimation stories would add volume without identifying a better method.
Next permitted unit: Draft a prospective package-level protocol with assigned transfer methods, opening chemistry, a standardized receiving system and delayed follow-up.
Activation trigger: The shipping package has first passed its own release gate and an independent methods reviewer accepts the assignment, unit and welfare plan.
Stop decision: Stop at protocol review if package chemistry cannot be measured, methods cannot be assigned prospectively or delayed outcomes cannot include every animal.

Reproducible search trail
Do direct transport studies validate a package combination or an acclimation rate for Neocaridina?
Taxon names: Neocaridina davidi, Neocaridina heteropoda, Neocaridina denticulata sinensis, Neocaradina spelling variant, red cherry shrimp, udang red cherry.
Concepts: transport, shipping, closed system, dry transport, acclimation, survival.
Search surfaces: publisher and DOI records, scholarly web indexes, institutional and journal repositories.
Outcome: The package-evidence boundary is refined because two direct transport experiments were located. Neither tests the house package or any drip rate, duration or receiving-water formula, so both operational questions remain open.
