The sentence
On Declare, the review step runs the dry run, and where it refuses, the sentence beside the Declare button reads:
Refused, and nothing was written.
A compiled answer adds no sentence of its own: the compile table is the answer. While it runs:
Checking the declaration against your book.
Where the dry run itself could not be read, the page says so and adds that this is a failed read, not a refusal, and nothing is compiled. In the table each row's state is one word, Bound, Partial, Unavailable, Refused or Unbound, and the row's why is the compiler's own reason.
What it means
Before a declaration is committed, Tightly compiles it: a dry run that binds each declared number to the engine that will defend it, against your book as it stands. The dry run writes nothing, whatever it answers. A refused compile is a full answer with its status saying so: the compiler could not honestly bind the scope, and it says why, per refusal, rather than approximating. No such category; no live buy plan season over the window; a scope whose share basis cannot be measured; an envelope no category pool can fund. Only a compiled answer opens the commit. Pending, failed, unreadable and refused all leave the button closed, and so does a compiled answer whose category funding check does not pass; that one prints the check's own reason beside the button.
Refused is not the only word for a number that is not bound. An envelope that some categories can fund and others cannot is Partial: it reserves what it can and names the unbound legs, each with its reason and its amount. A number nobody declared is Unbound: nothing was asked of the engine, so it is an absence, not a refusal and not a zero envelope. A binding no engine can make is Unavailable, with its reason.
What to do next
Read the Refused row's why; it names the thing to change. Pick a category the book holds, or a window a live season covers, or declare the envelope against a plan that funds the categories the scope touches. Then the dry run answers again by itself whenever the declaration changes, and a compiled answer opens the commit. Nothing was written on the refused one. The same compiler answers Ask Tightly's Preview what signing arms over a declaration already on the book, and it too writes nothing.
