Weekly routine 2026-05-30 — GPU compute duration port (New Idea mode)

[ford442]

Weekly routine — 2026-05-30

Updates weekly_plan.md for this week's run.

Mode: New Idea — last week's Web Worker module parse landed complete (typecheck + build green) and the Ideas section is exhausted.

Today's focus: GPU compute-shader port of the note-duration / sustain-span calculation (calculateNoteDurations, DURA-001 in utils/gpuPacking.ts) — move the per-load JS pattern scan onto a WebGPU compute pass, keeping the JS path as CPU fallback.

Plan changes in this commit

• Today's focus set to the compute-shader duration port.
• Marked done: Web Worker module parse, v0.55 oscilloscope registration (feat: register patternv0.55.wgsl (Oscilloscope) in shader selector #238), random-shader shuffle + v0.50 stepsLength (Add shader shuffle action and make v0.50 respect steps-length toggle #237).
• Appended two new Ideas: mobile/low-end "lite" render mode; dynamic per-instrument color palettes.
• Backlog reconciled.

⚠️ Note on branch state

This branch is ~98 commits ahead of main with no prior open PR — the Web Worker parse and other recent work live here un-merged. Flagged in the Backlog as MERGE STATE; main should be reconciled separately. This draft PR exists to make the working branch reviewable per process; it is not intended to be the vehicle that squashes 98 commits into main without review.

📝 Walkthrough

Walkthrough

Updated weekly_plan.md to reflect current development status: shifted focus to a GPU compute-shader port of note-duration calculation with CPU fallback, updated task checklists with new priorities and completion statuses, and refreshed the run log to document May 30, 2026 work outcomes.

Summary

Weekly plan status and focus update weekly_plan.md

Shifted "Today's focus" to GPU compute-shader duration port with CPU fallback and save-state behavior; reworked Ideas/Backlog/Done checklists to mark Web Worker parse as done-but-unmerged, add mobile lite and dynamic palette items, move compute-shader port to in-progress, and record pattern registration and shuffle-button completion; updated "Last run" record for 2026-05-30 with work confirmations and decoupled storage item notes.
