Per-person photo commands, where the mechanism is public and the album is not. Nothing identifying is in this repository: who the people are, what fires their photos and which file shows whom all live in one directory outside it, and the tests, the docs and the offline e2e run use three invented people instead. Several names in one message intersect -- "!alfa beta" is a photo with both -- and where an entry offers a choice the bot picks among the readings that actually have a photo, so a question the album could answer is not refused. A combination nobody photographed gets one line rather than silence, which from the group's side is indistinguishable from a broken bot. Scoping is enforced in the dispatcher, not in the handler: a command the group is not allowed resolves to nothing, so it is not answered, not counted as a command, and never named in a log line outside its own groups. A handler that quietly returned would leak all three. Commands are named by pseudonym (pack:p1), so the journal and command_uses say somebody asked for a photo and nothing about whose. Video works: the attachment goes out as data:video/mp4;filename=...;base64, which is the container's own spelling, read off its /swagger/doc.json. Told it is a photo, Signal renders a clip as an unplayable file. tool/tagger.py serves one page on loopback to fill the album in -- names are typed into the page, never as arguments, and it prints how many photos each command would have when it stops, because a command with zero is dead on arrival. Also renames the real people who were still sitting in the stats test fixtures. They remain in the history; the point is that nothing new is added to it.

"""A synthetic photo pack, built in a temp directory.

shapes, and a builder says which shape a test needs in the test itself. The

people are alfa, beta and gamma -- the real album's names are private and

must never appear in this repository, which is the whole reason the pack
