pub fn resolve_account(
id_store: &Arc<Store>,
identity_store: &Arc<Store>,
account_id: &str,
) -> Result<Option<(IdentityAccount, Arc<Store>)>, StoreError>Expand description
Resolve an account by id, checking id_store first — the
authoritative, per-account-isolatable primary, which is what preserves
the disposable-test-account isolation guarantee — and falling
back to identity_store’s read-through mirror
(IDENTITY_STORE_SCHEMA_VERSION v2,
docs/specs/SPEC_IDENTITY_STORE_SPLIT_2026_08_17.md §3.1) only when the
primary lookup misses. Returns the account alongside WHICH store it
came from, so a caller that later writes a status update (the OAuth
expiry probe below) writes it back to the SAME store instead of always
assuming id_store — writing to the wrong store would silently create
a second, never-read copy.
reagentx P0 review on PR #2632: before this, the link resolved via
identity_store (always global) but the account it pointed at could
still only exist in id_store, which is empty on a fresh, isolated
channel — the reported continuity bug wasn’t actually fixed end to end
without this fallback.
