* refactor(highway): lift 79 per-instance closure vars into `hwState` (R3c H lift) Collapses createHighway()'s 79 mutable closure `let`s into one per-instance `hwState` object. Scope-resolved rewrite via acorn + eslint-scope: 1059 edits (1057 references + 79 defs - the deleted `let canvas, ctx, ws`), with the four names shadowed in inner scopes (chartTime/ctx/notes/chordTemplates) resolved correctly so only closure-bound refs move. Enables the later module split: extracted renderer/ws modules close over `hwState` as a factory arg, so multi-panel plugins (highway_3d, note_detect, splitscreen) don't share one highway's state. Container is `hwState`, NOT `H` — `H` is already canvas height (70 uses). The frame-time gate caught that collision instantly (0 draws, `H._drawHooks is not iterable` in the shared draw-hook path). PERF (the whole risk): identical to the pre-lift baseline. Draw p50 2.1-2.2 ms, p95 2.7-3.0 ms (pre-lift 2.7-3.2), measured on the Arcturus feedpak, headless. Each closure-slot read became a `hwState.<slot>` monomorphic property load; the hot loop pays nothing. On-device: Byron confirmed the 2D highway plays smoothly. Tests: the ~30 highway JS suites brace-extract functions/patterns from the source; their state references + the monotonic-clock vm sandbox now use `hwState.<slot>` (the const _CHART_MAX_INTERP_MS etc. stay top-level, not lifted). node --test: 1030/1030 green. Two self-inflicted over-replacements caught and reverted (`_lefty` is a prefix of the 3D-local `_leftyCached`; `STRING_COLORS` a suffix of `DEFAULT_STRING_COLORS`) — substring replaces on the brace-extract regexes need word care. Transformer saved at ~/.local/share/feedback-editor/highway-h-lift.mjs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(highway): pin the setNoteStateProvider assertion to hwState._noteStateProvider (CodeRabbit) The [^}]* form matched an unqualified _noteStateProvider =, so a regression to closure-level state could still pass. Require the hwState-qualified assignment. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
