Each ISA's hand-written ENCODING_TABLE (the single source of truth) now lives in a per-arch tablegen/ metaprogram that flattens it and serializes committed binary blobs; the library #loads those into @(rodata) at compile time rather than compiling a table body. No arch keeps encoding_table.odin or decoding_tables.odin -- only a generated tables.odin loader and tables/*.bin. * Two-stage, type-checked pipeline: tablegen Stage A emits human-readable generated Odin, which compiles and serializes the blobs in Stage B. * encode() goes through encoding_forms(m); decoders are unchanged apart from x86's flattened 2-D index. Decode tables are byte-identical to the old ones. * build.lua: a LuaJIT driver for the metaprograms, validations, and tests, with cross-platform gating and a clear report. * Docs refreshed; the obsolete forward-looking plan in cross_arch_design.md trimmed to what was actually built. * Attribution headers added to all rexcode source files; the generators emit them so generated files keep them.
