Inbox thread disambiguation — Option A

Source: CASE-2026-000045 — "same contact split into two threads." Reality: the two threads are different clients (Hussam agency vs Manuel Collazo) reaching the same prospect from the same shared Nexus number, so they're correctly separate — the list just gives no clue why. Option A = a never-truncating client chip + muted, truncating campaign subtext on every row in the unified view.

Real prod data baked in: list pane is 320px default (260–520). Client names ≤18 chars (fit a chip). Campaign names up to 55 chars (always truncate). Drag the width + flip density below and watch nothing overflow.

Left = today. Right = Option A. Both panes obey the width slider + density toggle.

▲ BEFORE — two identical "Wilburn Wallace" rows

● AFTER — client chip + campaign subtext

In compact density the campaign subtext is dropped (too long for one line) and the client chip rides inline after the name — the disambiguator survives, the long campaign is one click away in the header.

Open-thread header

BEFOREAFTER

Header is always wide, so both client + campaign fit. Adds the client chip next to the existing campaign name.

BEFORE — campaign only; you must know which client owns this campaign.

AFTER — client named explicitly, campaign demoted to muted detail.

Why Option A holds at every width

Client chip (flex:0 0 auto, ≤18 chars) never truncates — it's the thing that answers "why two threads."
Campaign (flex:1; text-overflow:ellipsis) absorbs all the squeeze; full name on title= hover. Even the 55-char "Hispanics/FL Residents/…" row stays on one line.
Shown only in the unified view (no campaign filter). When you filter to one campaign, every row is the same client+campaign, so the labels hide as redundant.
Drag the slider to 260px (min) — the chip holds, the campaign just shows fewer chars. Nothing wraps or clips.
