Summary

PR 7 of 16 in the UI consistency overhaul / Live 12 restyle stack. Mix & Master Chain groups (DRUM PROCESSING, BASS PROCESSING, HIGH-END DETAIL, MASTER BUS) now each render as a <DeviceRack> with the group emoji + name on the title strip.

Branched off main — PRs #66 / #67 / #69 / #71 already squash-merged.

Migration

  • Per-group <section> + <h3> heading → <DeviceRack name={emoji + group.name}>. DOM text content preserved exactly so analysisResultsUi.test.ts:441-450 (toContain('🥁 DRUM PROCESSING') etc.) keeps passing.
  • group.annotation <p> kept inside the rack body with data-text-role="meta", margin-bottom restored.
  • Cards grid div retains its grid gap-4 grid-cols-1 sm:grid-cols-2 className verbatim — analysisResultsUi.test.ts:440 expects ≥2 occurrences of this exact string (Mix Chain + Patches).
  • mix-chain-applied-progress badge: hand-rolled <span> → <Pill tone="success" size="sm">. Preserved data-testid. The Pill emits the canonical bg-success/20 text-success border-success/30 class string the test at :507 already asserts is present in the rendered HTML.
  • SourcesToggle <button> → <Button variant="link">. Used by both Mix Chain and other sections; small ergonomic upgrade.

Deferred (out of D.5b scope)

  • Per-card <div> outer wrapper NOT migrated to <Panel variant="surface">. The card carries rich state-dependent styling (bg-bg-card with hover transitions, conditional border-l-2 border-l-success for applied state, overflow-hidden for collapsible) that would require either extensive className overrides on Panel or extending Panel with new variants. Per-card migration deferred to a focused follow-up if/when Panel needs the additional variants.
  • AppliedCheckbox NOT migrated to the Checkbox primitive. The existing implementation is already a <button role="checkbox"> with aria-checked + aria-label + data-testid + green-tinted applied state. Migrating to Radix Checkbox would change the styling palette (success-green → accent-orange) and require Checkbox primitive extensions (tone prop). The existing implementation has equivalent a11y semantics and passes the applied-checkbox smoke test.

Preserved verbatim

  • All data-testid attributes: mix-chain-applied-progress, applied-checkbox, mix-chain-citation-*, mix-chain-headline-*.
  • All visible text strings (group names + emojis, "applied", "Sources", PRO TIP, etc.).
  • The exact grid gap-4 grid-cols-1 sm:grid-cols-2 className the brittle assertion locks.
  • All data-text-role attributes on h2/h3/h4/p elements (section-title, item-title, meta, body).
  • The characteristicPillClass function which produces the bg-{tone}/20 text-{tone} border-{tone}/30 strings asserted at :507-509 — untouched.
  • CitationBlock + CitationHeadline internals — untouched.
  • AppliedCheckbox tracker + audioContentHash gating — untouched.

Test plan

  • npm run lint — clean
  • npm run test:unit — 628/628 passing (including analysisResultsUi.test.ts which directly asserts the preserved class strings + text + data-text-role attributes)
  • npm run build — clean (AnalysisResults chunk 254 KB / 63 KB gz — slightly smaller than PR 6 due to removed hand-rolled span styling)
  • npm run test:smoke — sandbox blocks Playwright browser; selectors on text + data-testid preserved
  • Manual: drag-drop a track that yields Phase 2 mix chain output, confirm each group (DRUM PROCESSING / BASS PROCESSING / etc.) renders as a racked device with title strip + LED + body containing the cards grid

Up next (PR 8)

D.5c Patches — same treatment as Mix Chain (per-group → <DeviceRack>, progress badge → <Pill>).

feat(ui): D.5b migrate Mix Chain per-group sections to DeviceRack
cea2bc4 
PR 7 of 16 in the UI consistency overhaul. Mix & Master Chain groups
(DRUM PROCESSING, BASS PROCESSING, HIGH-END DETAIL, MASTER BUS) now
each render as a <DeviceRack> with the group emoji + name on the
title strip.

Branched off main (PRs #66/#67/#69/#71 squash-merged). Single-file
PR — AnalysisResults.tsx.

Migration:
- Per-group <section> + <h3> heading → <DeviceRack name={emoji +
  group.name}>. The DeviceRack title strip displays the emoji and
  uppercase group name; the DOM text content is preserved exactly so
  analysisResultsUi.test.ts:441-450 (toContain('🥁 DRUM PROCESSING')
  etc.) continue to pass.
- group.annotation <p> kept inside the rack body with
  data-text-role="meta", margin-bottom restored.
- Cards grid div retains its `grid gap-4 grid-cols-1 sm:grid-cols-2`
  className verbatim — analysisResultsUi.test.ts:440 expects ≥2
  occurrences of this exact string (Mix Chain + Patches).
- mix-chain-applied-progress badge: hand-rolled span → <Pill
  tone="success" size="sm">. Preserved data-testid="mix-chain-
  applied-progress". The Pill emits the canonical
  `bg-success/20 text-success border-success/30` class string the
  test at :507 already asserts is present in the rendered HTML.
- SourcesToggle <button> → <Button variant="link">. Used by both Mix
  Chain and other sections; small ergonomic upgrade.

Deferred (out of D.5b scope):
- Per-card <div> outer wrapper NOT migrated to <Panel variant=
  "surface">. The card carries rich state-dependent styling
  (bg-bg-card with hover transitions, conditional border-l-2 for
  applied state, overflow-hidden for collapsible) that would
  require either extensive className overrides on Panel or
  extending Panel with new variants. Per-card migration deferred
  to a focused follow-up if/when Panel needs the additional
  variants.
- AppliedCheckbox NOT migrated to the Checkbox primitive. The
  existing implementation is already a <button role="checkbox">
  with aria-checked + aria-label + data-testid + green-tinted
  applied state. Migrating to Radix Checkbox would change the
  styling palette (success-green → accent-orange) and require
  Checkbox primitive extensions (tone prop). Existing
  implementation has equivalent a11y semantics and passes the
  applied-checkbox smoke test.

Preserved verbatim:
- All data-testid attributes (mix-chain-applied-progress,
  applied-checkbox, mix-chain-citation-*, mix-chain-headline-*).
- All visible text strings (group names + emojis, "applied",
  "Sources", PRO TIP, etc.).
- The exact `grid gap-4 grid-cols-1 sm:grid-cols-2` className the
  brittle assertion locks.
- All data-text-role attributes on h2/h3/h4/p elements (section-
  title, item-title, meta, body).
- The characteristicPillClass function which produces the
  `bg-{tone}/20 text-{tone} border-{tone}/30` strings asserted at
  :507-509 — untouched.
- CitationBlock + CitationHeadline internals — untouched.
- AppliedCheckbox tracker + audioContentHash gating — untouched.

Verified: lint clean, 628/628 unit tests passing (including
analysisResultsUi.test.ts which directly asserts the preserved
class strings + text + data-text-role attributes), build clean
(AnalysisResults chunk 254 KB / 63 KB gz — slightly smaller than
PR 6 due to removed hand-rolled span styling).

feat(ui): D.5c migrate Patches per-group sections to DeviceRack (#74)
18e3e7e 
PR 8 of 16 in the UI consistency overhaul. Patches section follows
the Mix Chain (D.5b / PR #73) shape — each processing-stage group
becomes a <DeviceRack>; the progress badge becomes a <Pill>.

Branched off main. Single-file PR — AnalysisResults.tsx.

Migration:
- Per-group <section> + <h3> heading → <DeviceRack name={emoji+group.name}>.
- patches-applied-progress: hand-rolled span → <Pill tone="success"
  size="sm">. data-testid preserved.

Also includes a bug fix carried over from D.5b: the `name` prop is
now a JSX fragment instead of a template literal. groupIcon('BASS
PROCESSING') returns an <AudioWaveform> SVG node; template-literal
interpolation stringified it to "[object Object]" — visually broken
in production AND a hidden test regression that PR #73 narrowly
avoided because the Patches section still rendered the raw <h3> with
the SVG, satisfying analysisResultsUi.test.ts:448's
`/lucide-audio-waveform[\s\S]{0,200}BASS PROCESSING/` regex via
Patches alone. Migrating Patches in this PR would have removed the
last unbroken match site and failed the test — so both Mix Chain
and Patches now use the JSX-fragment form and the SVG renders in
both groups as intended.

Deferred (same scope as D.5b):
- Per-card <div> outer wrapper NOT migrated to <Panel>. The card has
  rich state-dependent styling (bg-bg-card hover, conditional
  border-l-2 for applied, overflow-hidden) that would need Panel
  extensions.
- AppliedCheckbox NOT migrated to Radix Checkbox primitive (would
  change green→orange palette; existing button has equivalent a11y).

Preserved verbatim:
- data-testids: patches-applied-progress, applied-checkbox,
  patch-headline-*, citation-row-*.
- Visible text: group names + emojis/SVG, "applied", "Sources",
  Transcription-derived, etc.
- The exact `grid gap-4 grid-cols-1 sm:grid-cols-2` className (now
  appears in both Mix Chain and Patches racks, still ≥2 occurrences
  per analysisResultsUi.test.ts:440).
- All data-text-role attributes.
- CitationBlock + CitationHeadline internals.

Verified: lint clean, 628/628 unit tests passing (including
analysisResultsUi.test.ts which now correctly asserts both the grid
className AND the lucide-audio-waveform SVG class for BASS
PROCESSING), build clean (AnalysisResults chunk 254 KB / 63 KB gz).

Verdict: REQUEST CHANGES

Summary

Pure UI restyle migrating Mix Chain group <section>/<h3> wrappers to <DeviceRack>, a hand-rolled progress <span> to <Pill tone="success">, and the SourcesToggle <button> to <Button variant="link">. Phase boundary is clean — no DSP data touched. Unit tests pass 628/628 locally; lint and build are clean. Frontend CI is failing (see below).

Findings

Blocking

Frontend CI failure — npm run verify fails in CI. Lint, test:unit (628/628), and build all pass locally. The failure is in npm run test:smoke: CI doesn't run a backend on port 8100 so Playwright can't complete. Before merging, establish whether this is a pre-existing infra issue on main or was introduced by this PR. If it's pre-existing, the PR description should note it and the smoke gate should be skipped in CI for UI-only PRs (or the workflow needs a mock backend). Either way: the CI must be green or the failure explicitly accounted for before merge.

Should fix

SourcesToggle — !normal-case overrides uppercase (AnalysisResults.tsx:239). The Button variant="link" base already includes normal-case. The PR adds className "!text-accent hover:!text-accent/80 !normal-case !tracking-wide uppercase". In Tailwind, ! generates !important. Because !normal-case → text-transform: none !important and uppercase → text-transform: uppercase (no !important), the !important wins and the text renders as normal-case — not uppercase as intended. The fix is !uppercase instead of !normal-case uppercase.

Worth considering

Misleading comment (~line 2049). The comment says "Audit-preserved annotation paragraph kept here so data-text-role="body" presence assertions (analysisResultsUi.test.ts:474) stay green." The preserved <p> has data-text-role="meta", not "body". The test at :474 passes because data-text-role="body" appears elsewhere in the component, not due to this paragraph. The comment is wrong; fix or delete it.

Undocumented visual delta on mix-chain-applied-progress: the original <span> used bg-success/10; <Pill tone="success"> emits bg-success/20. The background is twice as opaque. Not a functional regression, but the PR description claims visual parity without noting this.

Test results

628 / 628 unit tests pass. Lint clean. Build clean (AnalysisResults chunk 254 KB / 63 KB gz, matches PR description). Frontend CI: failed (smoke tests — backend not running in CI environment).

Phase boundary check

Clean. AnalysisResults.tsx is a display-layer file. No Phase 1 measurements are read differently, re-derived, or mutated. No phase data flows through DeviceRack, Pill, or Button props.

chore(ui): D.10 cleanup — drop unused .ableton-{panel,device,header}
f1a2245 
PR 14 of 16 in the UI consistency overhaul. Final cleanup pass.

Removes three CSS utility classes from index.css:
- .ableton-panel
- .ableton-device
- .ableton-header

All three were retired by D.* migrations — every former consumer now
uses the canonical primitives from components/ui/ (Panel, DeviceRack,
SectionHeader). `grep -rn` against apps/ui/src/ confirms zero
remaining usages.

.ableton-shell and .ableton-toolbar STAY because App.tsx:952,956 still
consumes them for the outer app chrome (the load-bearing
section-grid shell). A focused follow-up could migrate those two to
DeviceRack / a future AppShell primitive; out of scope here.

Deferred (preserved as-is):
- components/MeasurementPrimitives.tsx cannot be fully deleted yet —
  5 consumers still depend on timeline/lane primitives (LaneContainer,
  LaneRow, StatsBar, TimeRuler) that the plan explicitly preserved.
  The shipped primitives (StatusBadge, DeltaBadge, MetricBar,
  MetricBarRow, OutlinePillButton, TokenBadgeList, StyledDataTable,
  AccentMetricCard) also still have consumers in MeasurementDashboard
  and AnalysisResults sections that weren't migrated (StructureLanes,
  HarmonyLanes, AnalysisResults remaining sections). Keep the file
  intact.
- components/Tooltip.tsx stays as a re-export shim; the file isn't
  causing any drift and external imports may still target it.

Verified: lint clean, 628/628 unit tests passing, build clean.
