- New sensory QA artifacts:

- Updated process chain:
- Verify every chemistry quest now has at least one setup artifact and one outcome artifact.
- Verify all new process outputs are referenced by quest gates (no orphan artifacts).
- Verify stevia path records solvent handling, thermal limits, and sensory protocol reproducibility.
Chemistry quests now require full bench protocol evidence: apparatus staging, solvent/reagent handling, and post-step records. Each quest now adds new process artifacts so QA can verify both setup and outcome.
Quest tree
Main path + branch notes
The chemistry tree remains linear in quest unlock order, but each quest now includes explicit multi-process lab phases (setup -> execution -> verification) with dedicated artifacts for each phase.
