Two routes, one output -- week 4 pack
Authored teaching scenario. Every observation, prediction and record below was written for this exercise. None was produced by running image software or by examining an image, and nothing here supports a claim about how any real tool or forensic technique behaves.

observations.csv lists what was observed about Output 7 and what
each proposed route predicts. tolerance.txt gives the scenario rule for how
close counts as indistinguishable.

route-cards.txt gives the two proposed processing histories as written steps.

evidence-menu.csv lists further evidence you could request. Two of the five
items do not exist, and their absence is marked with a reason. The three that
do exist are in evidence/, one file each. Choose one, write down what result
would favour which route, and only then open that file.

Not every available item separates the routes. That is not a flaw in the pack,
and an unresolved report that says what it asked for and what it learned is a
correct answer.

reveal/ holds what actually happened. Open it after your report.
