Last walked. 2026-07-02 cleanup-lane console addendum — Playwright real-dev-infra coverage now proves signed-in render, route-map contract, quick-action href order, ready curve catalog, 44 px submit target, non-positive-parameter client guard with no POST, real BFF linear retiming samples, fail-closed loading/unauthorized/malformed-catalog states, mobile no-overflow, and direct BFF 401/403/400/200 gates. Spec: apps/oshun/web/e2e/studio-aja-cleanup-lane-consoles.spec.ts.' '2026-05-29 automated runtime walk (Playwright headless) — render, /v1 data (2xx), console/page-errors, expected content, screenshot verified; live screen-reader, touch, offline, and telemetry-delivery checks pending a manual AT pass. Evidence: WALKTHROUGH/results/runtime-sweep-2026-05-29.md ; body re-derived 2026-06-03 from current source (lane-console architecture)

Purpose#

Leaf lane console that wires the real @aja/motion-processing time-warp curve factories. The operator picks a warp curve and parameter and the lane samples the (t)->t' speed profile across normalized time — the remapping a MotionRetimer applies to resample a clip.

Entry points#

  • Direct URL / bookmark — /studio/aja/retiming.
  • Studio nav — Domain-bridge studios section of /studio.
  • Sibling quick-action — "Open Aja Physics Cleanup workspace" (/studio/aja/physics-cleanup).

Layout regions#

page.tsx renders inside <ShellLayout active="studio">:

  • Workspace <StudioAjaRetimingWorkspace />:
    • <h1> "Aja Retiming Workspace" + summary (data-aja-retiming-summary).
    • The catalog curve descriptor list (data-aja-rt-curves, rows data-aja-rt-curve=<curve>) + the sample form (states below).
  • Route Map panel (data-aja-retiming-route-map, <h2> "Route Map"): 5 STUDIO_AJA_RETIMING_ROUTE_MAP entries — primary, scenes, exports, revisions, governance.
  • Quick-action lane: two Link.quickAction anchors. No breadcrumb panel.

States#

The lane fetches GET /v1/admin/aja/retiming on mount.

  • Loading — data-aja-rt-loading "Loading retiming curves…".
  • Unauthorized — data-aja-rt-unauthorized (401/403; default "Aja workspace scope required to view retiming.").
  • Error — data-aja-rt-error.
  • Ready (form) — data-aja-rt-sample-form.
  • Result — data-aja-rt-result with data-aja-rt-result-curve and the sampled rows (data-aja-rt-sample-row).
  • Validation error — data-aja-rt-sample-error (e.g. "Parameter must be a positive number." / "Sample count must be an integer ≥ 2.").

Interactions#

Sample form (data-aja-rt-sample-form)#

  • Curve — select data-aja-rt-field-curve (catalog curves; default linear).
  • Parameter — input data-aja-rt-field-parameter (default 2).
  • Sample count — input data-aja-rt-field-samples (default 5).
  • Sample curve — submit data-aja-rt-sample-submit; fires POST /v1/admin/aja/retiming/sample with { curve, parameter, sampleCount }.

Route Map#

  • Route entries (5) — non-interactive listing.

Quick-action lane#

  • "Open Aja Physics Cleanup workspace" → /studio/aja/physics-cleanup
  • "Back to Studio workspace index" → /studio

E2E coverage#

  • apps/oshun/web/e2e/studio-aja-cleanup-lane-consoles.spec.ts covers signed-in shell render, four-curve catalog, non-positive-parameter client guard with no POST, real BFF linear sample output (0, 0.5, 1, 1.5, 2 warped times), route-map count, exact quick-action hrefs, 44 px submit target, loading / unauthorized / malformed-catalog fail-closed states, mobile no-overflow, and direct BFF auth/schema/happy-path gates.

Data & contracts#

  • Reads: GET /v1/admin/aja/retiming (catalog: curves — each { curve, parameter, defaultParameter, description }).
  • Writes: POST /v1/admin/aja/retiming/sample → { curve, parameter, sampleCount, samples }.
  • Realtime: none.
  • Caching: client fetch on mount (cache: 'no-store'); SSR shell.
  • Auth/role check: BFF endpoint admin-scoped + fail-closed; route gated signed-in + studio via proxy.

Cross-references#

  • Parent: ../../studio-overview.md
  • Sibling (quick-action): /studio/aja/physics-cleanup
  • Component sources:
    • apps/oshun/web/src/components/studio/StudioAjaRetimingWorkspace.tsx
    • apps/oshun/web/src/components/studio/StudioAjaRetimingRouteMap.ts

Known downstream boundaries#

  • Route-map sub-routes are descriptive contracts; implementation status of those child pages is tracked separately from this leaf console.
