"I started a second amendment and now things look wrong"
Clozo allows one draft + one in-flight amendment per proposal. Trying to create a second hits a guard, but if you've somehow ended up with two competing change-orders (e.g., via parallel browser tabs), the wizard surfaces a `Resolve conflicting amendments` action.
Amendments stack chronologically — once one is signed, you can create the next. Concurrent amendments aren't allowed, both for legal clarity (client signs against a clear baseline) and for the renderer (the post-sign hook can only process one at a time).
Step by step
Open the Amendments tab
on the proposal detail page.
Look for two drafts.
If only one exists, you're fine — continue editing it.
If two
: discard the older one (date in the list). The newer one is canonical.
Send the canonical one
as normal.
Why this works this way
The "one in-flight" guard applies at create time. Two browser tabs both clicking Create amendment race; the second one's POST is rejected with a 409 Conflict and the wizard shows "draft amendment already exists". If you somehow get two drafts (rare; usually requires interleaved race conditions), the most recently saved one is canonical.

Creating an amendment (the 4-step wizard)
The amendment wizard at `/proposals/{id}/amend` walks you through line items, reason, preview, and email — in that order. Five minutes for a simple change, ten minutes for a complex one. The client doesn't see anything until you click Send on Step 4.
Troubleshooting & Reference
"The amendment wizard won't let me click Send"
The Send button is disabled or click does nothing. Three causes: a required field is empty, a duplicate draft amendment is open, or the parent proposal isn't in a state that allows amendments.

The 4 delta branches: Δ+, Δ−, Δ=0, Δ_REFUND
Every signed amendment falls into one of four branches based on (a) the sign of the cost change and (b) whether the proposal was already paid. Each branch fires a different document chain. This is the central conceptual map for the entire amendment system.
