Every account now lists standard Bitcoin addresses, so no one has to
derive them: Taproot (BIP-86, m/86'/1'/account'/0/0), which holds the
node's inscription, signs its acts and receives inscriptions, and
SegWit (BIP-84, m/84'/1'/account'/0/0) for payments, beside its npub
(NIP-06). An org is account 0 of its seed and its agents are accounts
1..n, so a wallet that opens an account finds the same addresses. The
lineage key tree page derives the same branches on mainnet paths and
lists the addresses in each agent's keyring.
The v1.2 tapkey (the npub's key, tweaked) is replaced by the standard
BIP-86 key; labs keyed by v1.1 or v1.2 keep their chain keys until
they are reset. Tests pin BIP-86 and BIP-84's own vectors.
