Loader buffers owned by this program's upgrade authority — not by the program itself. A failed or abandoned deploy leaves one behind, still holding its rent. If two programs on this network share an authority, both list the same buffers.
The interface every explorer and generated client resolves from chain to decode this program. Published through Program Metadata and signed by the program's upgrade authority — a deploy replaces bytecode and says nothing about the IDL, so the two drift unless this is published with it.
No open buffers.
Not published — No IDL has been published through Program Metadata, so nothing on chain describes this program's instructions.
Anchor's pre-Program-Metadata IDL account still holds 0.0796 SOL at 29T7B6tSYD49uVr9PfDs8cdyo8hBtjEagB1kff5fwAWb describing 0.1.0. It is frozen and its rent is unrecoverable: the program declares a plain #[program], so the instruction that would rewrite or close it was never compiled in.
