Contract 11.11.4

A verified player is its owner's alone: no other account may claim it as itself. A primary or alt on a tag another account has verified is refused, and when a tag is verified, every other account's primary or alt claim on it ends, with an account item on that account's timeline.

• elixir_track_player: add with relationship primary or alt (or a first player with no relationship) on a tag another account has verified fails not_entitled, with the Verify page's answer: if that player is yours, sign in to the account that verified it, or tell us. friend and watching are not refused, and a first player named either is added as that and not made the primary.
• elixir_timeline: account_claim_ended (facts player_tag, reason verified_elsewhere, was_primary, relationship) says a claim of yours ended because another account verified the player; account_claim_refused says a signup tag was not added for the same reason. Neither names the other account.
• The identity brief: a person who tracks players but has no primary (one ended this way) is told so, instead of being told they have no player.

A correction: shapes are unchanged. JSON API 3.2.0 is unchanged: POST /me/players runs the same tool and fails with the same Problem.
