Task 12 recorded which model each launch rode, but it surfaced only at
the tail of the session-detail metadata line, where nobody's eye lands.
With work and review models diverging per intent, "which brain did this"
is a routine review question, so the answer now sits beside the name that
did it.
One component, modelChip(), rendered wherever a name identifies a run:
the sessions list row, the session-detail header, the Focus header and
the working card's agent line. It borrows the session-id hash's register
— small, mono, dim — and takes no colour, because a model is not a state.
The vendor prefix a name repeats is dropped for the chip (claude-opus-4-8
→ opus-4-8, anthropic/x → x) with the whole string on hover; an
unfamiliar name is shown as recorded rather than guessed at.
A launch that never knew its model wears no chip at all — an inherited
default, or a session replayed from disk after a restart. The two
metadata lines that used to carry the model keep only what the chip
cannot say: "model inherited", and only when it genuinely is.
Tests lift the two functions out of the page and run them in node (skipped
where node is absent) for the shortening, escaping and silence; placement
and register stay source-level invariants, as board.html has no frontend
test runner.
