- lexer: backtick raw text literal — content verbatim, no escape
processing, common source margin removed at lex time; `${ }` raw and
`{{ }}` auto-escaping holes
- `{{ e }}` desugars to `esc(${e})` in parser.ml — a Call on the `esc`
in scope, so types/owner/emit/.wob/VM are untouched
- WO-E004 unterminated raw literal; WO-E005 newline inside "..." —
closes a hole where a missing quote silently ate the rest of the file
- wo-html: `Component` interface, `render_all`, `Layout`, README
- framework: `ok_html` joins ok_text/ok_json in http/types.wo
- site + shop restructured to one-feature-one-module MVC (view +
controller per directory, model at the root, bootstrap-only main)
- removed the filler `pad: Int` convention — verified unnecessary for
plain classes, interface dispatch, containers and actors
- corrected recorded claims: gap #1 blocks neither the build nor the
layout; a class crosses module lines, only a free fn is scoped
- docs/guides/language-surface.md — the full grammar inventory
- story 37 landed and moved to done/
Gates: oop-accept MET, oop-e2e 116/0, woc-test 556/0, site 11/0,

- language: `spawn Cls { fields }` expression (ctor semantics — fields
MOVE; result is the address); `actor M` parametric field type
(contextual like multi/map — actor stays a legal identifier); `send`
is a builtin free-fn name, not a keyword (shadowing rule applies)
- typing: M inferred from Cls's receive(msg: M); WO-E221 when receive
is missing, mis-armed, or M is not a class/record/union; send checks
addr is `actor M` and the message IS an M (silent when underivable);
ctor half of spawn delegates to the Ctor arm (completeness, ?T, E207)
- ownership: send's message TRANSFERS (sender's later use = WO-E301,
corpus-pinned); spawn's fields move via the ctor machinery; an
address is Copy
- emit: spawn lowers to ctor + LOADK receive's method index + BUILTIN
68; send is BUILTIN 69 with the message excluded from fresh-arg drops
(the runtime owns it now)
- runtime: wo_actor (moved-in instance, receive idx, growable FIFO
mailbox, one delivery fiber at a time); delivery reuses the fiber
context across messages and re-queues per message (fairness — an
actor never monopolizes); the runtime drops each message after its
receive returns; actor state/queued/in-flight messages are GC roots;
teardown drops everything (main-return reap included); loader knows
the two arities
- corpus: run/actor-echo (typed spawn/send, one-at-a-time delivery
interleaved with main by budget — output exact, ASan-clean),
compile-fail/spawn-no-receive (WO-E221), send-after-move (WO-E301)
- battery green: oop-e2e 92/0, woc-test, wovm-test, log-watcher 7/0,
employee 8/0, web-app 21/0, deps-accept 8/0
