- 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,
web-app 46/0, fibers 10/0, db-actor 8/0

-- http/secure.wo — framework v1 slice 2: the security middlewares and the

|
|
|

-- The response headers every deployment wants and nobody remembers.

-- HSTS is deliberately absent: TLS terminates at the proxy (the
|
|

-- in the proxy config next to the certificates.
