## What
Adds the design spec for the next version of the `twenty-last-contact`
public app, extending it from a single `lastContactAt` date column to
the three-column experience in the app's cover image on the All People
view:
1. **Last contact by** — the team member who last interacted with the
person (`ACTOR` field).
2. **Last contact** — the existing `lastContactAt` field, unchanged.
3. **Last contact item** — the email or meeting that was the last
contact, as a clickable record (`MORPH_RELATION` → message |
calendarEvent).
All three columns always describe the same single most-recent
interaction (atomic "newer wins" update).
This PR contains the **design doc only** —
`docs/superpowers/specs/2026-06-29-last-contact-by-and-item-design.md`.
Implementation follows.
## Why
The app today only answers *when* you last talked to someone. These
fields also answer *who* on your team and *through which* email/meeting,
matching the product vision in the cover.
## Key design decisions
- **`lastContactBy` is an ACTOR**, with the team member resolved from
the interaction's participants (`messageParticipant` /
`calendarEventParticipant` both carry `workspaceMemberId` +
`workspaceMember`).
- **No provider (Gmail/Outlook) logo.** That data lived on
`connectedAccount`, which v2.7
(`drop-connected-account-standard-object`) removed from the
app-queryable workspace schema. Confirmed acceptable; the actor still
shows the member + an email/calendar source.
- **`lastContactItem` is a MORPH_RELATION** following the SDK pattern
used by `attachment` / `noteTarget` / `taskTarget` (shared `morphId`,
one field per target, reverse relation on each target object).
## Reviewer notes
- **Load-bearing open risk** documented in the spec: how to *write* a
morph relation through the app's GraphQL API — no app in the repo writes
morph yet. The plan starts with a spike on this; if morph writes aren't
supported from an app, the fallback is two nullable `RELATION` fields
(`lastContactMessage` / `lastContactCalendarEvent`).
- No code/behavior change yet — safe to merge or hold as the design of
record.
