Three related extraction bugs surfaced in the EAC session all rooted in the line-based state machine: 1. `<style ... />` (JSX self-closing) had no separate `</style>` for the "skip until close" mode to exit on, so the state machine stuck and every `data-impeccable-variant` marker after it got missed. Accept reported `handled: false, error: "Variant N not found"`. 2. A variant whose entire `<div ...>...</div>` sits on one line had its body silently discarded — the marker line was `continue`d past, and the extractor started capturing from the next line, which usually belonged to a different variant or the wrapper close. 3. `extractCss` kept scanning for `</style>` after a self-closing opener, greedily swallowing every subsequent variant div as "CSS". Result: a mangled carbonize block stuffed with HTML and a duplicate variant rendered below. ## Fix Replaced the line-based state machine with a string-based flow: - `stripStyleAndJoin(lines, block)` returns the wrapper text with `<style>` elements fully removed. Handles self-closing, same-line open+close, and multi-line open/close. Markers inside CSS strings (e.g. `@scope ([data-impeccable-variant="1"])`) are gone by the time extraction runs — no false positives. - `extractInnerByAttr(text, attrMatch)` is a balanced-tag matcher that walks the joined text finding `<TAG ...attrMatch...>…</TAG>` with proper depth tracking for nested same-tag elements. Handles single-line, multi-line, and deeply nested variants. - `extractOriginal` and `extractVariant` are thin wrappers over the above. - `extractCss` gets explicit same-line handling: returns null for self-closing (nothing to carbonize), extracts inner content via regex for same-line `<style>…</style>`, falls through to the existing multi-line path otherwise. ## Tests New tests/live-accept.test.mjs with four cases — all failing before, all passing after: - Self-closing `<style />` with dangerouslySetInnerHTML - Single-line `<style>…</style>` - Multi-line `<style>...</style>` (regression baseline) - Discard restores the original element after self-closing style Wired into `bun run test`. Full suite passes. Credit: precise repro + root-cause trace from the other agent in the EAC session. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
