The domains/ folder: one file and what it compiles to

What one domains/ file holds, what each key compiles to, and the checks that read it.

One domains/ file is one Domain and what it does: the site, or the email it sends from. SiteBuilder compiles it; the pages here read what it makes.

domains/leaseline.app.mdx

role: email
email: { mailboxes: [dana] }

Mail sends from dana@leaseline.app.

roleUsed forwhat the Domain serves; email adds its sending records (POST /{namespace}/domains/{domain}/authenticate)—

Checks

CheckIt holdsWhat dev prints
S2Every send passes a code-tier Check before it goes.sequences/cold-email-thread-founder.mdx:5 S2 steps.second sends with no code-tier Check. Add guards: [customer-collision].

Refusals

CodeFix, then the call that clears it
claimCut the line, or cite the Offer term that grants it. Then POST /{namespace}/conversations/{conversation}/answer.
customer-collisionSend it to their CSM instead: the Contact leaves the List. Then POST /{namespace}/leads/{lead}/assign.
domain-authenticatedAdd the 3 DNS records shown; it passes once they resolve, often within an hour. Then POST /{namespace}/domains/{domain}/authenticate.
mailbox-warmWait for the warm-up to finish, 14 days from day 0; warm intros keep running. Then POST /{namespace}/mailboxes/{mailbox}/warm.
owned-by-a-personLeave it to the person who owns it: the draft waits in their queue. Then POST /{namespace}/tasks/{task}/assign.
priceGet the discount approved, or quote at the floor. Then POST /{namespace}/approvals/{approval}/approve.
spam-brakeSend to a smaller List, or wait an hour for the rate to fall. Then POST /{namespace}/messages/{message}/broadcast.
visit-captureServe your Site from your Domain and publish the visitor notice; lookups start when both pass. Then POST /{namespace}/domains/connect.

sample
CallWhat it does
POST /{namespace}/domains/{domain}/authenticateAuthenticate writes a Domain’s SPF, DKIM and DMARC records and verifies them before its first send. Emits Domain.authenticated.
POST /{namespace}/domains/{domain}/verifyVerify checks a Domain’s DNS, ownership and certificate again and records each result, with the fix for any failure. Emits Domain.verified.
POST /{namespace}/domains/connectConnect attaches a hostname a Startup already holds and verifies ownership through DNS. Emits Domain.connected.
POST /{namespace}/mailboxes/{mailbox}/warmWarm ramps a new Mailbox from a few sends a day to its cap over two to four weeks. Emits Mailbox.warmed.

Compiled, not written: edit the records it reads (compile table; cap), then regenerate. Every step runs from a sentence or a line of code. In your words: the CRM words you know, and where each lives here.
