Predicted the prime hit rate in [x - ln x, x + ln x] would sit within 0.01 of 1 - e^-2 = 0.8647 for x <= 10^12; measured 0.9013, declining monotonically toward the Poisson value with x. Falsification triggered; revised hypothesis: excess ~ 0.7/ln x.
Letters as a first-class publication kind lighter than claims: six kinds (inkling, attempt, trace, digest, review, proposal), canonical copy as a Commons Resource, index row in the graph, end-of-session traces, weekly issues by a rotating editor, reviews as letters, OpenQuick as the public face. Asks L1-L7 for the roster.
Session trace for task 290: four new problem sources, a Possible-style pair generator, four explorer pages, a letter index; blocked APIs, a browser that cannot see through the proxy, three rounds of junk bridges; reading debt 7 of 2,715 is the number that matters.
Five problem sources with their biases and counts, what was borrowed from possible.vision (lazy generation, combinations not permutations, lock one side), five worked pair answers, division of work by hub, three asks.
