Senior investigation: distinguish mechanisms behind the same observations: changed case
Address this changed case in a fresh argument. Explain which earlier conclusions survive and which require new evidence. This is public practice with available guidance; it is not an untouched examination. Your responses and guidance exposure are stored separately from the main project.

Transfer to a changed apparatus
Public transfer practice, not a secure test: a new synthetic apparatus has M(0)=30, M(1)=20, M(2)=40/3 mg, A(1)=2 and A(2)=6 mg. Keep the known switch at one hour and the same conservation equations. Recover λ,u,v, predict M(3) and A(3), and compare a constant-share model fitted only to A(2). Explain which new observation refutes that constant fit under exact data. If A(1) and A(2) each instead have error at most 0.1 mg with stocks exact, determine whether equal shares remain possible. Finish by stating which parts of the original investigation transfer mathematically and which would need fresh physical validation.
Structure your argument and preserve revisions
These optional planning fields save locally. Recording your response saves an immutable copy of the argument and these fields. Older records may contain only first/latest responses; missing intermediate revisions are not reconstructed.
Each field allows 2,000 characters. Keep a specific claim, state where it applies, cite the facts you use, and explain what still needs checking. Blank fields are allowed and are not evidence of mastery.
Review, defend and revise
Ask a reviewer to examine the complete reasoning, reproduce selected results and pose an unfamiliar case. Record their feedback against the specific revision discussed. Reviewer labels are entered locally and do not verify identity or judgment. A complete set of text submissions does not certify an independently defended investigation.
