The PHP transfer replay (pre-push 13.3) spent its whole 7,200 s case in the head side's evidence pass. A probe on one PMPro graph named the cause: not compute -- context adds ~20% engine time -- but OUTPUT. Each evidence request listed every method its scope reached, up to 1,845 rows; 200 requests into the bundled Braintree SDK returned 52,831 rows, 9.4 MB, against 211 rows without context, over 22,125 requests in a 3 GB container. `affected_context` only ever attaches a location in a changed file, and every other row was checked (real file under the root, usable extent) and discarded. The scan now sends the changed files; the engine itemises those and folds the rest into one `context_elsewhere` row carrying exactly what that check reads. With no safe file list the engine itemises everything, as before. Equivalence: unit controls over valid, missing-file, no-extent and outside-root cases, with and without a changed-file row; a real-Joern control; and on PMPro itself, 2,440 relationships and zero gaps decided identically from both forms, 52,831 rows down to 3,241 with the most referenced file as the change.
