== Deadlines and money are set by the service, not by you ==

Two values decide whether a transaction survives, and neither is left to whoever generated the XDR:

* '''Timebounds.''' The service sets <code>max_time</code> from the signing-round SLA of the question class — 24h for MAJOR/REGULAR/FINANCIAL, 72h for CRITICAL. A window you supply is overwritten. The watchdog pings missing signers at 25%, 50% and 75% of the window, and past expiry it rebuilds the transaction automatically: new sequence, fresh deadline, and every previously collected signature explicitly invalidated with its signer notified. Silent expiry is not possible.
* '''Fee.''' Priced at the market from Horizon <code>fee_stats</code> at build time and again at every rebuild, because a rebuilt transaction flies into a later and possibly busier network. Per [[Assembly 0024]], a constant base fee is not acceptable. When the sanity cap binds, the record says so rather than pretending the number was a market rate.

An explicit no-timebounds mode exists for accounts whose policy accepts an open-ended envelope. It is a deliberate per-transaction choice, never a default.
