+# 24 — A model chip beside every agent name
+
+**Status:** Backlog
+**Priority:** Low — the data is already there; this is putting it where eyes are
+**Type:** Feature
+
+Task 12 made the board record the model each launch used, but it
+surfaces only at the tail of the session-detail metadata line —
+"… · task/04-… · claude-opus-4-8" — where nobody's eye lands. With
+per-intent models configured, which brain did the work becomes a real
+question ("was that review sonnet or opus?"), and the answer should
+sit beside the name that did it: a small chip, everywhere an agent
+wears its name.
+
+## Context
+
+- Task 12 (landed) records the resolved model (or inherited) on the
+  session record; the Sessions detail line proves the data flows.
+- Where agent names appear today: the sessions list entries
+  ("Olive · a83fae45"), the session-detail header, the Focus view's
+  header, the card face's agent line while working ("Cleo · 7m"),
+  and header session chips on the Board view.
+- Design system: machine-produced text is Plex Mono; the session-id
+  hash beside the name ("a83fae45") is exactly the visual register
+  this chip belongs in — dim, mono, small. Colour means state, and a
+  model is not a state: the chip must stay neutral.
+
+**Affected areas:** `board.html` only; possibly the state payload if
+any of the name-bearing views lacks the model field today.
+
+## What to build
+
+- One chip component: the model string in small mono on the dim
+  neutral used by the id hash, rendered immediately after the agent's
+  name wherever that name identifies a run — sessions list, session
+  header, Focus header, the card's live agent line.
+- Display the resolved model as recorded, shortened for the chip by
+  dropping the redundant vendor prefix (`claude-opus-4-8` → chip
+  `opus-4-8`, full string on hover/title). Inherited runs wear the
+  resolved name too if known; if the launch genuinely didn't know
+  (pre-12 sessions replayed from disk), the chip is absent, not a
+  guess.
+- Old persisted sessions without the field render exactly as today —
+  no chip, no placeholder.
+
+**Out of scope** — tempting neighbours left alone:
+
+- Recording anything new (12 did that); no per-event model tracking.
+- The ticker line — one-line narration stays terse; the chip lives
+  where names are headings, not prose.
+- Any colour-coding of models.
+
+## Acceptance
+
+- [ ] Sessions list, session-detail header, Focus header and the
+      working card's agent line all show the chip beside the name for
+      a fresh launch; hover reveals the full model string.
+- [ ] A pre-existing session file without the model field renders
+      chip-less and un-broken.
+- [ ] The chip is visually the id-hash register (mono, dim), adds no
+      new colour meaning, and doesn't shift the layouts it joins —
+      names and timestamps stay aligned.
+
+## Open questions
+
+- None.
+
+## Notes
+
+Prompted (2026-07-30) by reading a session where the model sat at the
+end of the metadata line: with work/review models diverging per task
+12's intent split, "which model did this" is now a routine review
+question, and the answer was hiding.
