- 16 tasks complete: arena, object model, borrow word, containers, RC + budgeted cycle collector, wob_build, validating loader, interpreter core (dual dispatch), object opcodes, drop-map unwinding, builtins + DB_STUB + TRAP, ICALL, wovm CLI + just recipes - 13 test suites × 2 dispatch flavors (ASan+UBSan) + CLI smoke, all green - .wob v1 format pinned in src/wob.h + docs/plan/oop-vm/00-wob-format.md - wo-rt.c reference event-loop preserved for sub-project 2 This is Iteration 2 of the OOP milestone; compiler front (Iteration 3) is in progress on this branch. They meet at Iteration 4 (emitter+e2e).

/* wob_build.h — in-memory .wob assembler for tests and fixture generation.

* Deliberately a SECOND, independent encoding of the format (the loader is
|
|
* the first): builder/loader disagreements surface as test failures,
|
|
* cross-checking docs/plan/oop-vm/00-wob-format.md. Test-side only — never
|
|
* linked into wovm itself. */
