 ## 2026-08-03
 
+- **Complete workload phase ownership** — Added typed animation and retained-configuration hooks to all seven retained workload definitions using preallocated host scratch, eliminating the renderer's remaining create/layout/animate/apply dispatch switches without moving RAF, telemetry, or renderer lifecycle into workload code. Moved the Benchmark Ipsum corpus and Advanced Shaping timeline beside the other authored workloads, and moved the self-contained Advanced Shaping conformance target under `benchmark/targets/conformance` behind the same literal selected-target dynamic import. Coupled raster targets remain in place pending a session adapter that preserves their warm load/run/dispose lifecycle. The post-move Chromium run completed all 42 dual-backend Presentation workload cells with visible pixels and one renderer per lane; all 19 isolated headless conformance scenarios passed, including three exact 68-frame Advanced Shaping timelines with zero warm readiness waits.
 - **Workload controller boundary** — Made all seven retained workload definitions own typed app-private construction and layout hooks, so the renderer selects those behaviors only through the exhaustive registry. Moved Icon Grid layout, virtual-window calculation, assignment validation, recycled-entry positioning, pan integration, and frame-delta smoothing beside its canonical public `Text` example. Main and Presentation now derive descriptions, amount labels, fixed/selectable font behavior, preload grouping, and pan/zoom capability from the typed catalog instead of duplicating workload-ID policy. Renderer, canvas, RAF, GPU timer, telemetry, font transactions, active pool ownership, and teardown remain host infrastructure; no public package API was added. Chromium 149 completed all 42 Bitmap/MTSDF/Slug × WebGPU/WebGL2 × seven-workload Presentation cells with visible pixels, one renderer per lane, and no reported console failure.
 - **Workload scene and conformance locality** — Moved Text Ladder, Zoom Text, Off-axis / 3D, Dynamic Layout, Paragraph Stress, and Paint & Effects layout and animation behavior beside their public `Text` constructors, leaving the retained renderer as a dispatcher and Icon Grid virtualization as the next controller extraction. Extracted the conformance React hierarchy from the root application while preserving one host-owned renderer for retained comparisons and exclusive finite captures. A deterministic delayed-peer regression proved the realtime MSDF / Slug comparison could refresh one candidate generation early; the private scene now retains the last complete target pair, defers target resize, publishes both retained objects in one task, rolls both back on failure, and drains an in-flight pair before disposal. Seven focused lifecycle cases cover renderer-state restoration, success, failure, abort, partial readiness, rollback, and delayed resize without admitting a renderer-wide grouped-publication API.
 - **Benchmark workload policy and target ownership** — Added one typed catalog for all nine live benchmark workloads, including exact Main/Presentation reset defaults, font policy, controls, interaction, preload, and surface kind. Benchmark rail metadata and runtime resets project from that authority, and URL parsing normalizes unknown workload IDs inside the selected mode before downstream policy executes. Moved technique-invariant text styling and color motion below `workloads/shared` and added a static/dynamic source boundary that rejects workload dependencies on renderer implementation modules. Reclassified public loader/Worker parity as conformance, moved direct Wasm dependencies into one shared selected-ABI adapter, and retained boundary tests that reject raw Wasm imports elsewhere.

 Main and Presentation are exclusive URL-selected root presentations. Presentation owns the scene and floating chrome directly: it does not render Main's header, workload rail, control aside, compact sheets, navigation, or hidden Conformance Activity. Each route owns one persistent render host, canvas, animation loop, GPU timer, and telemetry ring for its backend generation. Workload and technique changes activate a replacement scene while the committed scene continues rendering, then atomically swap and dispose the old scene resources; compatible font changes update retained `Text` objects in place. React Suspense owns genuinely cold asset loading, while scene selections are committed with `useTransition` after preloading so warm transitions do not replace the visible scene or reset the graphs. Runtime diagnostics and the live workload probe require one active renderer, one active canvas, and a peak concurrency of one through rapid presentation, workload, and technique changes. Main enters Presentation through one accessible expand-corners icon rather than a text label. Presentation's workload, font, and shaping-case selectors use the official shadcn Base UI `Select`; Base UI owns portal placement, outside-press dismissal, Escape handling, focus restoration, and keyboard listbox behavior, while the application renders selected human labels explicitly instead of exposing stored keys. A fixed left-edge viewport slot top-aligns one compact shadcn `ButtonGroup`, so workload-specific controls grow downward or scroll without moving the dock anchor. Each dynamic value owns a shadcn `Popover`: global GPU/GL and DPR selectors, workload sliders and toggles, Advanced Shaping selection/text/timeline panels, and MTSDF-only stroke/shadow controls. Informational descriptions and controls unavailable to the selected technique do not enter the Presentation dock. MTSDF paint starts with zero stroke and shadow disabled. One 1.5× presentation-scale boundary enlarges the top controls, telemetry, dock, and payload labels; inverse-scale viewport constraints, group-specific transform origins, and a 32 CSS px safe area keep every floating group clear of host-frame corners and on-screen without overlap at 1,280×1,280. Presentation surfaces use restrained shadcn-radius corners, plain 80%-black composition without a backdrop filter, and opaque borders. The graph rail owns one continuous background with opaque dividers instead of exposing translucent seams between child charts. Canvas render captions and navigation status remain Main-only. No visible exit action competes with the compact top-right telemetry stack, and Escape returns to Main. The comparison workloads retain framework-neutral `Text` objects behind the active presentation. Paint & Effects advances one circular per-word chromatic sequence directly on the renderer RAF through the synchronous paint-only batch path; shaping, paragraph layout, geometry, and React do not drive individual color frames. Its source span topology and update object are retained across animation frames, while `Text` retains the glyph-to-paint index plan. Animate, speed, hue, opacity, shadow, stroke, and layout-bounds controls mutate retained scene state and never enter the scene-rebuild path. Ordinary font-size and paragraph-volume changes may replace a generation because they alter glyph geometry or authored text. Resident layout-width, compatible viewport-width, font-size, font-fixture, and Dynamic Layout changes stage every affected `Text`, publish through Three.js matrix traversal, and reposition only after the complete synchronous lifecycle publication; `ready` remains a cold/error observation channel rather than warm control flow. Rapid controls pass through a latest-value serialized drain so obsolete intermediate values are never staged.[^comparison-workload] Live controls invalidate only an explicit capture, not the continuously updated typed-array telemetry, so metric labels and graphs do not disappear while a slider moves. Font selection retains the active benchmark shell and its last telemetry rather than showing an intermediate empty metric frame; comparison workloads additionally retain their canvas while the next font prepares. The live probe observes causal, monotonically increasing paint revisions, rejects layout work or batch replacement during paint updates, and proves comparison-workload font switching preserves canvas identity and never empties the CPU metric. Dynamic Layout stages all three paragraph reflows as one batch and positions the complete trio after lifecycle publication; it never recenters a mixture of old and new layouts. Neutral inspection frames remain default-on and share the same typed configuration boundary.
 
-Every live benchmark identity resolves through one typed catalog under `apps/benchmarks/src/workloads/`. The catalog owns labels, descriptions, exact Main and Presentation defaults, font policy, controls and ranges, pan/zoom capability, preload policy, and surface kind; URL parsing normalizes an unknown workload inside its selected mode before font or control policy executes. Main and Presentation derive scene descriptions, amount labels, font selection, preload grouping, and pan/zoom capability from that authority rather than repeating workload-ID switches. Text Ladder, Zoom Text, Icon Grid, Off-axis / 3D, Dynamic Layout, Paragraph Stress, and Paint & Effects each own their authored content and public `Text` construction. Their typed definition objects also own scene construction and layout; Text Ladder, Zoom Text, Off-axis / 3D, Dynamic Layout, Paragraph Stress, and Paint & Effects own animation behavior. Icon Grid owns its layout, virtual-window calculation, assignment validation, recycled-entry positioning, pan integration, and frame-delta smoothing, while the host still owns the active pool and telemetry until the instance-controller slice. Their technique-invariant content-width, text-style, and color-cycle utilities live below `workloads/shared`; a source-boundary test rejects static or dynamic imports from any workload module back into renderer implementation files. The route-owned renderer, RAF, telemetry, font delivery, transactional publication, and disposal remain benchmark infrastructure. Conformance React composition lives under `surfaces/conformance`: both the retained comparison and finite captures can receive only the host-owned renderer, while finite low-level dispatch stays below `benchmark/targets/conformance` and `benchmark/targets/measurement`. Those targets share the explicitly named `targets/shared/direct-wasm.ts` dependency adapter only after target selection. The public missing-sibling loader Worker is conformance because it proves authenticated Worker bytes and loader fallback behavior; it is not a rendering product target. Boundary tests reject workload imports back into renderer implementation and reject direct font-baker or Wasm URL imports outside the shared adapter, preventing raw tooling from leaking into the normal Presentation module graph.

 Timed playback compares each frame with the latest requested location rather than the last committed scene, so an in-flight preload receives exactly one request and cannot be superseded by a duplicate transition that skips workload-default initialization. Presentation captures Space at the window capture boundary to start or stop timed playback even while a button, switch, slider, select, or combobox owns focus; matching key-up activation is suppressed, while inputs, textareas, and editable text retain ordinary space entry. Arrow navigation remains disabled on interactive controls.
