Scans yield cooperatively in bounded batches. Name-address retention and reverse-trie construction are each limited to65,536 entries/nodes and fallback module-array candidates to64 (`native-index-capacity`); exceeding capacity does not prove absence. Rendered type text has a64MiB UTF-8 cache-workspace guard, separate from the64MiB encoded-report admission, and64 nested rendering frames (`native-type-text-capacity` / `type-nesting-capacity`). Genuine cycles are malformed; unsupported type kinds are explicit coverage failures. Native row/text admission runs before allocation or retention. Unused generic parameter names are read on demand from the same stable metadata snapshot. There is no cross-inspection file cache; validated immutable Evidence is reused for session views.
ELF RELATIVE writes into zero-fill are kept as a private virtual-pointer overlay. Unresolved supported-width symbol relocations, including RELA PLT entries, remain unknown; stored zeros never establish no-body. COPY, TLS descriptor, REL, packed APS2 and other unsupported relocation encodings fail closed. Input bytes are unchanged.
ELF RELATIVE writes into zero-fill are kept as a private virtual-pointer overlay. Unresolved supported-width symbol relocations, including RELA PLT entries, remain unknown only for the bytes their ELF ABI relocation type covers; an adjacent 32-bit relocation does not make a separate 64-bit method slot unknown. Stored zeros never establish no-body. COPY, TLS descriptor, REL, packed APS2 and other unsupported relocation encodings fail closed. Input bytes are unchanged.
Native address queries batch exact64-bit hexadecimal `addresses` and `states` (`code`, `no-body`, `unknown`), intersecting indices and pagination. Numerically equal address spellings match; original row indices and every shared-body alternative survive:
