 ## What a trace looks like
 
-Each trace is written as natural-language prose in four to seven steps that mirror how a careful reader would work. An orientation step identifies the chart type, the axes and the cohort. Two or more read steps extract concrete quantities from the plotted data, for example the position of a dashed end-of-life threshold, the endpoints of the steepest fade trajectory, or the per-bin midlines of a swarm plot, in which every cell appears as one point within its parameter bin. One or more reasoning steps then combine the reads through the materials-science operation the question requires, such as a cohort median, a least-squares slope converted to per-thousand-cycle units, a linear interpolation to a threshold crossing, a quartile boundary, or a count of strongly correlated metric pairs on a correlation matrix, at the magnitude threshold the question states. The final step states the graded answer exactly. Questions whose correct answer is an instructed refusal token, for example when an asked ageing mode is not among the plotted panels or when the cohort median never reaches the threshold inside the plotted window, receive traces that walk the presence or censoring check before concluding with the token.

Where a read locates a value against an axis, the trace first states the axis's drawn tick pitch, so the calibration a pixel reader needs is explicit. Where the answer admits a genuinely independent second route, such as a count split for a median, closure of a census against the plotted total, or a third point on a fitted line, a closing check verifies it before the answer is stated. The final step states the graded answer exactly. Questions whose correct answer is an instructed refusal token, for example when an asked ageing mode is not among the plotted panels or when the cohort median never reaches the threshold inside the plotted window, receive traces that walk the presence or censoring check before concluding with the token.
 
 Each question type is generated by at least one dedicated script, and most admit more than one genuinely different solution path. The library realises 56 template styles across the twelve families, and the styles differ in which reads they take and in what order, not merely in wording. For example, one quadrant-count style tallies all four quadrants and checks that they sum to the plotted total, while its sibling filters by sign along one axis first, and one fade-rate style works from the endpoints of the steepest curve while its sibling normalises the capacity drop before scaling. The style for each row is selected deterministically from the row identifier, so the library is exactly reproducible.
 
 ## A worked example
 
-The trace below ships in the `fade_trajectory_protocol_overlay` config and is reproduced verbatim. It shows the anatomy in miniature: the orientation states how this particular render is coloured, two reads pick the endpoints of the steepest trajectory off the pixels, the arithmetic converts the drop into the requested units, and the trace then openly distinguishes its own chord estimate from the least-squares convention that the graded answer follows.
