Named evidence gapWhich package combinations protect Neocaridina during real transport?
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
One wet closed-transport duration experiment and one atypical dry chilled experiment measured direct Neocaridina outcomes, but neither compared or validated the Molt & Moss breather-bag package, density, weather gate and receiving protocol.
What would answer it
Versioned package trials with internal temperature, bag chemistry, density, transit history and survival through at least seven days.
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: Which exact packaging, density and weather histories support a bounded shipping release gate.
Primary endpoint: Live arrival plus survival and condition through at least seven days, with temperature and bag chemistry treated as exposures.
Minimum design: Versioned package trials across independent shipments or validated transport simulations with prospective package comparisons and delayed follow-up.
Required reporting: Package version, film and water volume, oxygen method where used, animal source and density, fasting, insulation, heat or cold pack, complete internal temperature trace, duration, carrier events, opening chemistry, receiving protocol and package-level outcomes.
Community can contribute: Consenting recipients can return logger, opening-chemistry and delayed-outcome records under one frozen package protocol.
Community observations cannot establish: A delivered package, carrier scan or immediate live-arrival count alone cannot validate a weather gate or long-term animal outcome.
Closure rule: Each conclusion applies only to the versioned package, density, route and temperature history tested; material packaging changes reopen the gap.

Current research allocation
One active bounded validation
Only the declared protocol and endpoint receive active validation time. A result cannot be generalized beyond the tested system.
Why this allocation: Versioned test shipments are already part of the operating release gate, so the project can generate package-level evidence without inventing a separate animal exposure.
Next permitted unit: Complete the declared P3 test-shipment record for one unchanged package version, including temperature trace, opening chemistry, receiving protocol and seven-day outcomes.
Activation trigger: A planned non-customer test shipment meets the existing animal source, package, logger, receiving-system and follow-up requirements.
Stop decision: Pause after the declared matrix is complete, after any material package change, or after an adverse event. Review the bounded result before scheduling another unit.

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.
