Anchor: ⋯ in the chat header (44×44). Popover 256px, r14, raised + hairline.
The new row is the only one with a leading terracotta glyph; everything else
stays neutral. Scrim starts under the header so the session you're handing
off stays legible. NEW badge is temporary (2 releases).

The boundary card is the hero — it sits above the fold-adjacent brief and
uses the same two-list grammar as folder share. Mobile stacks the two
columns; the honest strip spans full width on a raised background.
Role is a two-up card segment, not a pill row, so the read-only sub-label
always reads. Continue is present-but-disabled to set the roadmap.
The @Frank remove glyph draws at 18px but takes a 44×44 hit slop.

Short code is the fallback for anyone who can't scan: 8 chars, mono, 27px,
0.1em tracking, ambiguous glyphs (0/O, 1/I) excluded from the alphabet.
Countdown is caption-weight — informational, never alarming, until <5 min
when it turns amber.

Waiting is neutral, not terracotta — nothing is running yet. The banner is a
pinned card above the composer (not a toast) because the lock persists.
Composer is dimmed to 45% and shows a lock glyph — it is visibly present,
not removed, so the return to normal is obvious. Recall is the only
danger-tinted control on the screen. Both banner buttons are 44pt tall.

Mirror of Frame 2, second person. Facts first (who / what / where), then the
same boundary grammar, then the brief. The cost note is a row, not fine
print — “runs on Panda's computer and model account” is the single
question every recipient asks.

Expired keeps the content visible at 32% so the recipient can still tell
what they missed — but every action collapses to a single Close.
Same shell serves DECLINED, CANCELLED and RECALLED with a swapped
banner string and chip.

Light swaps tokens only — no layout change. Accent darkens to #C75A38
for AA on warm white; primary button text goes white. Success/muted
marks keep their roles so the two lists stay distinguishable without
relying on colour alone (glyph shape carries it).

Terracotta means in progress — the ribbon is the only tinted surface.
Attribution appears only once a session has had more than one actor;
solo sessions keep the plain YOU / CLAUDE labels. The recipient's own
label carries a 5px accent tick. Tool rows are untouched — the actor of a
tool call is always the agent.

Same stream, different chrome. The initiator's ribbon is neutral — they are
not the actor, so no terracotta. The composer is replaced here (not dimmed):
during IN_PROGRESS there is no draft to preserve, and the bar carries the
one escape hatch. Streaming output keeps rendering live.

The result is structured, not prose — verdict + findings + verification +
next steps — so it can be rendered as a card, injected into the session as
context, and later diffed. Severity is a 7px dot: red / amber / secondary.
Every finding carries a mono file:line. Verdict chips use the status
palette (amber = attention, not failure).

RETURNED is green — the loop closed successfully; the verdict chip carries
its own (amber) severity independently. The card is an in-stream artefact,
not a modal, so it stays scrollable in history. Mark reviewed is the only
transition to COMPLETED. The system row is deliberately plain: the user
should know the result became context.

Rows are 60px, whole row tappable, chevron trailing. The status chip is
the row's only colour. In progress pulses (1.4s, opacity 1→.45) — it is
the one live state. Expired and Recalled share amber because both mean
“ended without a result”; Declined / Cancelled are grey — a non-event.

Desktop keeps the mobile information order but splits it across two columns: decisions left,
consequences right. The boundary card goes back to its native two-up form. The dialog footer
restates the cost of the action next to the primary button — desktop users click faster.
Sidebar: the active session row gains a status dot (neutral = waiting) and a lock glyph;
other rows are unaffected, so a handoff never disturbs the rest of the fleet.

The guest's sidebar shows exactly one session plus an explicit “not shared with you” row —
absence is stated, never implied. Finish & return is a pane-header button on desktop
(persistent, top-right) instead of the mobile pill above the composer.
The result card grows to 820px and findings go two-up; the card is capped so long results
scroll inside the stream rather than stretching the pane.
