Detect
Define the smallest relevant unit or mass that can be located and measured.

Small does not mean low risk

FUURAA thesis
Risk changes with scale; it does not monotonically decrease.
Engineering map
Turn the title into engineering objects that can be observed, measured and reviewed.
Each layer states the boundary to establish and the evidence needed for the next decision.
Interact
Assess surface-area effects, field response, transport and biological or ecological contact.
Resolve
Plan retrieval, neutralisation, monitoring and response when direct handling is impossible.
Verification questions
Write the questions first, then decide whether a demo, test, pilot or operating record can answer them.
Each question needs an object, conditions, denominator, threshold and accountable decision owner.
- 01
Which hazard becomes harder to observe at this scale?
- 02
Can one missing unit matter biologically or operationally?
- 03
What unique material behaviour appears?
- 04
How long and where must residual effects be monitored?
Evidence to preserve
Enable the next reader to reconstruct conditions, results, failures and the decision.
A conclusion alone loses reviewability; raw records, configuration and exclusions matter too.

Scope boundary
State what this evidence still cannot be generalised to.
- 01
Neither nanoscale dimensions, low individual energy nor soft material is a general safety claim.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
