Postal mail

A letter is a file.

A send

Quoted, held, printed, posted.

The price is the provider's own. Credits are held before the provider is asked, and a refusal releases the hold.

The postal pane edits this code.

Each edit in the pane, an address, the mail class, a paragraph, is written back into the file. Its Python and Rust twins say the same letter.

Where it stands

Built and tested, no letter mailed yet.

The route tests run the real routes, keys, ledger and Drive with a fake only at each provider's API. A Click2Mail production account answers read-only calls; no job has been submitted (docs/postal.md).

Measured, not guessed

The three postcard sizes and their ink-free zones were measured in Lob's own templates. A 6 × 9 card quotes at $1.03.

A lost submit is unknown

A submit whose answer was lost is recorded unknown, keeps its job id, and the clock reads its real state later.

Paper in, later

Renting a mailbox that scans paper mail is modelled. It answers no_inbound_provider until one is set up.
