- `woc` now emits `.wob` that `wovm` runs: emit.ml lowers the typed, owner-annotated AST (scope-stack registers with a >64 WO-E401 diagnostic, Lua-style call windows, ICALL by slot, dedup const pool, drop maps, line tables, implicit terminators); disasm.ml backs `--dump-bc` goldens. - Ownership lowering consumes the four owner tables verbatim; RESIDUAL is the only source of borrow ops, coalesced per operand. Review caught the emitter consuming only 2 of owner.ml's 4 residual producers — an assignment-anchored aliasing violation ran to exit 0 instead of trapping; fixed, plus a backstop raising WO-E404 for any residual region left unconsumed. - Conformance harness `scripts/oop-e2e.sh` (`just oop-e2e`): four fixture kinds with exact outcomes — byte-exact stdout, one WO-E### anchored on `error CODE:`, numeric trap code, gc trace. 25 fixtures incl. pricing-demo logic, the ownership suite, and DB_STUB's parse-but-trap. `tests/` un-ignored so the corpus is actually tracked. - `woc build` produces a self-contained binary: wovm copy + appended image + 20-byte trailer, self-exec via /proc/self/exe. Verified relocated outside the repo, argless, and against adversarial trailer corruption. - Milestone 1's five spec criteria all MET (`just oop-accept`). Criterion 3 closed by WO-E405 — the entry must return `Int`, since program mode already says its return value is the exit code — which deletes the leak class without adding return-type metadata to the format. `gc/held-cycle` retired: an externally-held cycle is not expressible in a post-exit pump. - New spec: inferred GC + incremental per-shard tri-color mark-sweep, retiring `@gc` and reference counting. Story gains iterations 7b (that work) and 9b (`@table`, relations, compiler-checked query); `.dev/reference` gains a sparse System.Linq checkout. Priority: 5→6→7 (log-watcher) then 7b, 8, 9, 9b.
