- Modules: `use`/`pub`, directory-as-module, per-module symbol resolution (a
flat first-wins merge silently ran the wrong `pub fn` body), six reserved
stdlib namespaces typed UNKNOWN-BUT-RESERVED.
- Surface: `and`/`or` (own precedence tier, short-circuit, Bool-only), `${}`
interpolation desugared at parse time, `const`, break/continue with
drop-correct exits, do-while, inline-fn rejection.
- switch expr/stmt: required `default` over scalars/Text, arm unification,
EQ/EQS+JZ lowering, per-arm drop scopes with N-way JOIN-DROP; `default`
sorted last by a shared lowering order (textual order made arms dead).
- typedef records: structural, same shape = one class entry; `?name: T`
nullable-by-shape; emit_ctor fills omitted defaults; `type` as field name.
- Enum variants: all-bare unions = int ordinals; any-payload = one class
entry per variant, tag IS the header class_id (no header field, no format
bump); exhaustive switch without `default`; arity checked both directions.
- Payload escape modeled as move-out (pointer-kind fields only — a scalar
escape is a copy); caller reaps owned heap temps passed by borrow: two
unbounded LSan-blind leaks, 10.5 MB -> 1.5 MB flat over 300k iterations.
- Fixed en route, each with a RED repro: dead E209 builtin-arg check and
`int_to_text` missing from both types.ml builtin tables (both segfaulted
wovm), multi-file phantom double-report, emit_ctor's field temp clobbering
dst in tail position (pre-existing), warnings swallowed without an error.
- Two fenced VM builtins: `int_to_text` (13), `variant_tag` (14).
- 14+565 unit (was 14+401), corpus 71 (was 32) plain and under wovm_asan,
wovm-test + cli_smoke green. Log-watcher 307 -> 93 diagnostics (85 E101 /
4 E207 / 1 E208 / 3 W202); the 5 non-E101 residuals await Task 7 grammar.
Completes plan 2 Tasks 7-8. owner.ml: mutable-value-semantics flow analysis
producing the four plan-3 emitter tables (moves, drops incl. LIVE-MASK for trap
unwinding, rc with elision, residual borrow sites) plus WO-E301-304 two-site
diagnostics. Alias questions run over canonicalized places, so a double-mut
reached through let-bound aliases lands in the residual table like the direct
form; dump.ml's contract notes the emitter must coalesce guards per operand.
main.ml: directory discovery, cross-file programs (symbols merge before bodies
check), diagnostics ordered by (file,line,col), new WO-E214 for a name declared
in two files. New docs/plan/oop-vm/01-error-catalog.md (14 emitted + 10 reserved
codes), un-ignored so both plan tracks can cite it; justfile regains woc-*.
builtin_scalars is now the five that work: Int, Bool, Text, Timestamp, Id.
Money/SKU/Float and the abstract_types allowlist are gone — `abstract` never
lexed, and Float had no literal syntax and no wob kind, so no value could exist.
Fixtures and samples retype Money->Int, SKU->Text. The abstract newtype feature
is rejected outright (verdict row adopt->reject); haxe-parity Task 7 keeps `is`.
nullable-types-implementation.md corrected: ?T is plumbed but UNENFORCED
(E211-213 declared, never emitted; probe exits 0), handed to haxe-parity Task 6
as next work item. Records all 10 dead codes incl. E205 — interface satisfaction
is unchecked. crates/rt keeps its Money/SKU fixtures (opaque strings, Stage 2).
Gate: build warning-clean, 14 + 264 checks 0 failures, pricing golden exit 0,
docs/examples histograms unchanged (13/70, zero WO-E225).
