Origin
Hard and fast is traditionally explained through nautical language for a ship held firmly aground, with hard describing the ground and fast meaning fixed. Merriam-Webster dates the modern fixed or inflexible sense to 1822. A surviving specialist definition in Admiral W. H. Smyth's Sailor's Word-Book is from 1867, later than that figurative evidence. The maritime derivation is therefore plausible and conventional but not proved by a printed nautical citation earlier than the figurative idiom, so it should not be presented as certain.
