The counters said how MUCH and never which file, so a run that was working normally and one that had
wedged produced the same screen: `done` stops moving either way. A photograph is around thirty encodes
and a video is three plus a poster ladder, and none of that was visible from outside.
So the run keeps a transcript and the button opens it.
Every rung reports itself by CONSTRUCTION. Ten `variants.push` call sites became one `add`, which is
the point — a rung added later is described without anybody remembering to describe it. The slow
stages that produce nothing until they finish say so BEFORE they start instead: the HEIC decode, each
video rung, the poster frame. Those are the pauses that read as a hang.
`?since=<n>` is what keeps it cheap. The transcript is thousands of lines and polls once a second, so
sending all of it every tick would be the same megabyte over and over; the client keeps what it has
and asks for the rest. No `since` means everything, which is what a modal opened mid-run wants.
The transcript lives in the shared slot, not the modal, so closing it does not throw away the run —
somebody who looks, closes, and looks again is watching one run rather than two. `startedAt` is what
identifies a run, because `n` restarts at 1 and appending across a boundary would interleave two.
Polling, not a socket. Each line transfers once and the events are seconds apart, so a second
transport to open, authenticate and reconnect would buy nothing.

It sat under the two folders it acts on, which was right while it was a detail of setting fofos up. It
is not one: a stale `derived/` is why a picture is missing from a page somebody is looking at, and the
fix was three sections away in a card about where the site lives. Beside Build and Publish it reads as
what it is — the third thing you do to a site, and the one that has to happen first.
The card keeps what needs room: the progress bar, the failures, the run history.
Shared through `useGlobal`, keyed `['fofos-admin','media-sync']` — a slot in the app-wide query cache,
so no provider has to wrap the bar and the panel together and a third reader is one line. Not a
context: this codebase has one for Save because a SECTION owns that state and announces it upward.
Nobody owns this one; it is a fact about a folder, which is what a keyed slot is for.
`useGlobal` shares the value and not the work, so the fetching is a separate hook with exactly one
caller — the button. The bar is mounted whenever the plugin is open and the Administration card is
mounted only sometimes, so the thing that is always there is the thing that asks. Two callers would
poll the same endpoint twice a second.
Gated on `rootSet`, not `ready`: sync reads a folder on this machine and never speaks to fofos.
