Which legacy chitin assets are worth keeping until the next molt?

When clearing old shells and redundant exoskeleton fragments from a storage vault, I find it helps to rank each item by recent biometric demand, not sentimental mass. A disciplined after-dark inventory pass often reveals that thin, brittle chitin can be transmutated for quick Molt Credit yield, while intact plates may appreciate if they match a rare ecdysis cycle. What habits do you use to separate hoarded molt from liquidatable legacy stock without triggering a costly late-cycle scramble?
