# Admin Reseed Welcome

`POST /v1/admin/handles/{handle_id}/reseed-welcome`

## Request

- Base URL: `https://www.tandem-cc.com` (the document declares no server; this is the origin it was published from)
- URL: `https://www.tandem-cc.com/v1/admin/handles/{handle_id}/reseed-welcome`
- Auth: none declared

Wipe an existing handle's welcome thread(s) and re-seed with the
current template.

Brian m_b4372290-follow-up (Leslie session 2026-04-25). The welcome
template was retired mid-session — Leslie had already received the
old chatty version. This endpoint backfills: deletes any existing
welcome thread(s) that the well-known welcome address sent to this
handle, then runs the seed function again so the user sees the new
minimal welcome.

Why the matcher is conservative: only deletes threads where
from_handle is the known welcome sender AND the subject matches
a known welcome phrase (current OR previous). This intentionally
doesn't cascade to "any thread between Brian and the user" because
we don't want a future bug to wipe real conversation history.
