# G62 -- Names and types are evidence-based, never guessed
|
|
|
|
A symbol is renamed only on a recorded basis (a string it prints, a cross-reference chain, a debug menu, a live-memory
|
|
datapoint, a community label with provenance). No evidence, no name — an address-named placeholder is honest and greppable.
|
|
A model may propose a name; it may never assert one. Types come from access patterns locked into the bytes; structure is
|
|
unified before any field is named. **At bank time:** a canonical type file exists from the first bank and grows one proven
|
|
field at a time; a draft may not bank a duplicate definition of a shape the file already has, nor a raw address cast (every
|
|
absolute address it touches is a declared, typed symbol); a width or signedness is proven by the bytes, never guessed — the one
|
|
place a type moves bytes, and the one the permuter cannot reach.
|
|
provenance: BFM gen3-standards rule 1 + the sotn-decomp style guide ("better to leave it unnamed than name it wrongly"); the bank-time clause from BFM decision-log "P33.5 S91-b" (types as a banking and width lever — 1,232 drafter-invented definitions at 100%)
