Changes touching this path

• the pathspec option group gets its first production consumer, and being inert turns out to have been invisible by construction: all five .groups attachments sat inside cfg(test), so Pathspec::keep returned at its is_active guard on every production call and no test could see it, because a filter that never runs changes no output - which is why delta.rs claimed in the present tense that diff, status and show were all served by that line while none of them attached the group. diff and status now attach it, diff narrowing at #1541's seam so rows, --stat and --content inherit one filter rather than each applying its own, and a -- separator arrives with it because a pathspec needs a way to say the rest are paths. Two states the ticket did not name are where the real bugs were. status builds its delta lazily, gated on the human format, so --porcelain and --json never reached the seam at all and attaching the group alone would have left both machine formats printing an unfiltered listing at exit 0 - the format an agent reads, which is the caller this class is dangerous to; and with no working change status returns before reading the tree, so loot status zzz would still have exited 0 in the primary checkout while passing every test on a seeded temp repo, since a seeded repo is never empty. Both are now answered from the seam, the second gated on is_active so pathless callers pay nothing. status also stops silently dropping its argument, which removes it from OPEN_BUT_TAKES_NONE and leaves 23 - by the other route, taking paths properly rather than declaring NO_ARGS, and the list's prose implies the latter is the fix for the names still on it, which would foreclose the better answer for surface, converge and ferry. The false sentence is narrowed rather than deleted and carries why it was written a ticket early, in delta.rs, flags.rs, the census doc and CONTEXT.md. Eight breakages proved the tests non-vacuous, planned before they were written, and dropping both attachments - the exact pre-ticket inert state - turns six of six process tests red plus the census pin (#1493) 35ed624c · dbf3dbe6…

Renames are not followed. loot's tree maps a path to an address, so a rename is a delete and an add. This list is the history of the name, not of the bytes.
