Two layout changes to the block above the prompt.

Pinned message trailer

Baked for <duration> used to live at the bottom of the transcript, which put the todo panel between it and the input box and made it scroll away as soon as you moved back through history.

The trailer is extracted from AssistantMessage into an exported MessageTrailer (it owns the model/final/duration/suppressed/aborted memos, which moved with it). AssistantMessage renders it inline only for history; Session renders the last message's copy in the pinned block, between the todo panel and the prompt slot:

     All good.

     [✓] wire the resolver
     [•] backfill the tests
     ✺ 1 of 3 finished · ctrl+b to show full TODO

     Baked for 1.6s

Spacing moved with it: the todo panel takes over the blank row that used to come from the trailer's marginTop, and the pinned trailer adds its own top gap only when no panel precedes it (spaced prop, driven by a new todoActive predicate shared with TodoPanel). Verified in all four combinations — both visible, trailer only, panel only, neither.

Side effect worth flagging: the pinned trailer no longer scrolls away.

Width-tiered busy footer

While a turn runs the row carries the spinner, the interrupt hint, the modified-file count and context/cost. As the terminal narrows, flexbox first squeezes the gaps to single spaces, and below ~85 columns the row wraps to two lines and clips the cost:

   ▰▰▱▱▱▱▱  esc            ctrl+b 12 modified     1.2M (98%) · $123.4
            interrupt      files

It now sheds by value instead:

Width	Shed
≥ 108	nothing
88–107	ctrl+p commands
< 88	+ the modified-file count

The spinner and interrupt hint always stay. Measured at 120/100/90/80/70 — all render on one line (118, 98, 88, 78, 68 columns used).

Notes

• DIVERGENCES.md: two new rows, plus edits to the two existing rows this touches (the trailer-dedup row and the busy-arm hint row).
• CHANGELOG.md: an entry for each change.
• New footer-width.view.test.tsx (3 tests across widths) and a pinned-position test added to message-trailer.view.test.tsx.
• Full TUI suite: 262 pass, 1 fail. The failure (@ mention popup lists files before references and agents) is pre-existing and unrelated — it fails identically on a clean main checkout with ENOENT /tmp/opencode/state/kv.json.
