Braille canvas averaging now tracks active vs. inactive sample counts separately to preserve background colors. Performance governance allows frozen-backdrop reuse during intro. Viewer-content rendering introduces caching and composition. Visual witness fixtures are updated accordingly.\\n\\n## Changes\\n\\n**Title-Scene Rendering and Startup Intro Optimization**\\n\\n| Layer / File(s) | Summary |\\n|---|---|\\n| **Braille cell color averaging by sample activity**
`src/ui/averaging-braille-canvas.ts`, `spec/title-screen.spec.mjs` | The braille cell accumulator now branches on `sample.on`, accumulating RGB into foreground when active and background when inactive. `activeCount` and `inactiveCount` track sample distribution separately. New `brailleCellForeground` and `brailleCellBackground` helpers compute averages using these counts with fallback paths. `averageRgb` is generalized to accept a count parameter. Test validates that active and inactive dot samples preserve their respective background colors within a cell. |\\n| **Performance governor intro-active frozen backdrop support**
`src/app/workspace/title-scene-performance-governor.ts`, `spec/workspace-title-performance-governor.spec.mjs` | Early-return for `introActive` is removed, allowing the frozen-backdrop-reuse logic to apply. `shouldReuseLowRateBackdrop` now permits reuse when either `idleTitleScreen` or `introActive` is true (previously only `idleTitleScreen`). Remaining checks for `frozenBackdropAvailable`, cache validity, and posture remain intact. Three test updates validate: introActive + lowRateFrozenBackdropActive produces frozen posture; startup intro compositing occurs without retracing; frozen backdrop persists across refresh windows without transitioning to live tracing. |\\n| **Title rendering with presentation surface caching**
`src/app/workspace/viewer-content.ts`, `src/ui/title-screen.ts` | Introduces `titlePresentationSurface` cache in renderer state and a new `titleFrameSurface(...)` composition function that blits backdrops onto a cached surface and conditionally applies `paintTitleScreenPresentation(...)` based on editor presence and startup intro completion. Frozen and retained backdrops now finalize via composition instead of raw/copied surfaces. Braille rendering hardcodes `suppressPresentation: true`. `cacheAgeSeconds` is removed from governor input; `shouldActivateLowRateBackdrop` no longer requires `model.startupIntroComplete`. Unused helpers `titleBackdropAgeSeconds(...)` and `copySurface(...)` are removed. `paintTitleScreenPresentation` is re-exported from title-screen.ts. |\\n| **Test infrastructure updates**
`spec/workspace-helpers.mjs`, `spec/workspace-title-braille-sampling.spec.mjs` | `mockJeditTheme()` adds a `variables: new Map()` field. Two adaptive-Braille-sampling tests initialize `mockTitleScreenModel` with `startupIntroComplete: true` and `startupFileModalOpen: true` instead of `false`. |\\n\\n**Bunny Scene Camera Configuration**\\n\\n| Layer / File(s) | Summary |\\n|---|---|\\n| **Bunny camera Z-position flip**
`scenes/bunny.jedit-scene`, `spec/title-scene-neon-dispersion.spec.mjs` | Camera `position[2]` changes from `2.55` to `-2.55`. Test assertion validates that `scene.camera.position[2]` is less than `scene.camera.target[2]`. |\\n\\n**Fixture Updates**\\n\\nVisual witness fixture digests for `graphite-braille-logo-visible`, `graphite-braille-logo-faded`, and `solarized-dark-braille-late-orbit` are updated in `spec/fixtures/title-scene-visual-witness.json` to reflect the new Braille averaging and rendering behavior.\\n\\n---\\n\\n## Estimated code review effort\\n\\n🎯 3 (Moderate) | ⏱️ ~25 minutes\\n\\nThe changes span three independent but tightly coupled subsystems (Braille averaging, performance governance, viewer-content rendering) with dense logic in averaging and composition functions. The heterogeneous nature of edits—mixing algorithm refactoring, control-flow logic, state caching, and test infrastructure—demands reasoning about interaction patterns across multiple domains. Fixture digest changes require validation against observable rendering behavior.\\n\\n---\\n\\n## Possibly related PRs\\n\\n- [flyingrobots/jedit#106](https://github.com/flyingrobots/jedit/pull/106): Directly related—continues the same title-scene performance pipeline, touching identical code paths in `viewer-content.ts`, `title-scene-performance-governor.ts`, `averaging-braille-canvas.ts`, and `title-screen.ts`.\\n- [flyingrobots/jedit#97](https://github.com/flyingrobots/jedit/pull/97): The startup title-scene performance governor introduced here is the foundation for this PR's frozen-backdrop reuse logic during intro scenes.\\n\\n---\\n\\n## Poem\\n\\n> 🎬 Braille cells now know their active souls, \\n> Frozen backdrops grace the intro's stroll, \\n> Presentation surfaces cache and compose, \\n> While bunny cameras flip their Z's— \\n> A symphony of rendering flows! ✨\\n\\n\\n\\n\\n

Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.\n### Available skills\n- imagegen: Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas. (file: /opt/codex/skills/.system/imagegen/SKILL.md)\n- openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains. (file: /opt/codex/skills/.system/openai-docs/SKILL.md)\n- plugin-creator: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata. (file: /opt/codex/skills/.system/plugin-creator/SKILL.md)\n- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /opt/codex/skills/.system/skill-creator/SKILL.md)\n- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /opt/codex/skills/.system/skill-installer/SKILL.md)\n### How to use skills\n- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.\n 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n 5) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.\n- Context hygiene:\n - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.\n - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.\n - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.\n- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.\n","\nFilesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted. Network access is enabled.\nApproval policy is currently never. Do not provide the `sandbox_permissions` for any reason, commands will be rejected.\n","turn/started",{"_439":440,"_85":920},{"_101":-5,"_41":446,"_447":921,"_449":450,"_451":922},[],"inProgress",{"_451":924,"_439":440},{"_925":926,"_90":927},"activeFlags",[],"active","thread/started",{"_930":931},"thread",{"_932":-5,"_933":-5,"_934":935,"_936":450,"_501":502,"_937":15,"_938":-5,"_939":-5,"_41":440,"_940":941,"_196":-5,"_167":942,"_943":224,"_506":944,"_451":945,"_75":946,"_947":450},"agentNickname","agentRole","cliVersion","0.124.0","createdAt","ephemeral","forkedFromId","gitInfo","modelProvider","openai","/opt/codex/sessions/2026/06/09/rollout-2026-06-09T04-24-34-019eaaa0-03ea-7201-8cf0-83923ed1f846.jsonl","preview","vscode",{"_90":455},[],"updatedAt",[],"messages",[951],{"_41":952,"_953":954,"_955":956,"_957":956,"_461":958,"_451":959,"_463":-5,"_960":31,"_961":962,"_963":964,"_965":-5},"a7984004-7256-4314-a13c-74dcc0d56f67","author",{"_94":338,"_196":-5,"_961":974},"create_time",1780979073.330897,"update_time",{"_970":45,"_971":972},"finished_successfully","weight","metadata",{"_966":967},"recipient","all","channel","l1239dk1",{"_968":969},"inline_comments",[],"content_type","parts",[973],"@codex enabled default runtime instrumentation for the current title performance investigation.\n\nUpdate: `9a43dca Perf: enable default session instrumentation`\n\nWhat changed:\n- jedit now starts with the perf HUD visible by default.

Braille canvas averaging now tracks active vs. inactive sample counts separately to preserve background colors. Performance governance allows frozen-backdrop reuse during intro. Viewer-content rendering introduces caching and composition. Visual witness fixtures are updated accordingly.\n\n## Changes\n\n**Title-Scene Rendering and Startup Intro Optimization**\n\n| Layer / File(s) | Summary |\n|---|---|\n| **Braille cell color averaging by sample activity**
`src/ui/averaging-braille-canvas.ts`, `spec/title-screen.spec.mjs` | The braille cell accumulator now branches on `sample.on`, accumulating RGB into foreground when active and background when inactive. `activeCount` and `inactiveCount` track sample distribution separately. New `brailleCellForeground` and `brailleCellBackground` helpers compute averages using these counts with fallback paths. `averageRgb` is generalized to accept a count parameter. Test validates that active and inactive dot samples preserve their respective background colors within a cell. |\n| **Performance governor intro-active frozen backdrop support**
`src/app/workspace/title-scene-performance-governor.ts`, `spec/workspace-title-performance-governor.spec.mjs` | Early-return for `introActive` is removed, allowing the frozen-backdrop-reuse logic to apply. `shouldReuseLowRateBackdrop` now permits reuse when either `idleTitleScreen` or `introActive` is true (previously only `idleTitleScreen`). Remaining checks for `frozenBackdropAvailable`, cache validity, and posture remain intact. Three test updates validate: introActive + lowRateFrozenBackdropActive produces frozen posture; startup intro compositing occurs without retracing; frozen backdrop persists across refresh windows without transitioning to live tracing. |\n| **Title rendering with presentation surface caching**
`src/app/workspace/viewer-content.ts`, `src/ui/title-screen.ts` | Introduces `titlePresentationSurface` cache in renderer state and a new `titleFrameSurface(...)` composition function that blits backdrops onto a cached surface and conditionally applies `paintTitleScreenPresentation(...)` based on editor presence and startup intro completion. Frozen and retained backdrops now finalize via composition instead of raw/copied surfaces. Braille rendering hardcodes `suppressPresentation: true`. `cacheAgeSeconds` is removed from governor input; `shouldActivateLowRateBackdrop` no longer requires `model.startupIntroComplete`. Unused helpers `titleBackdropAgeSeconds(...)` and `copySurface(...)` are removed. `paintTitleScreenPresentation` is re-exported from title-screen.ts. |\n| **Test infrastructure updates**
`spec/workspace-helpers.mjs`, `spec/workspace-title-braille-sampling.spec.mjs` | `mockJeditTheme()` adds a `variables: new Map()` field. Two adaptive-Braille-sampling tests initialize `mockTitleScreenModel` with `startupIntroComplete: true` and `startupFileModalOpen: true` instead of `false`. |\n\n**Bunny Scene Camera Configuration**\n\n| Layer / File(s) | Summary |\n|---|---|\n| **Bunny camera Z-position flip**
`scenes/bunny.jedit-scene`, `spec/title-scene-neon-dispersion.spec.mjs` | Camera `position[2]` changes from `2.55` to `-2.55`. Test assertion validates that `scene.camera.position[2]` is less than `scene.camera.target[2]`. |\n\n**Fixture Updates**\n\nVisual witness fixture digests for `graphite-braille-logo-visible`, `graphite-braille-logo-faded`, and `solarized-dark-braille-late-orbit` are updated in `spec/fixtures/title-scene-visual-witness.json` to reflect the new Braille averaging and rendering behavior.\n\n---\n\n## Estimated code review effort\n\n🎯 3 (Moderate) | ⏱️ ~25 minutes\n\nThe changes span three independent but tightly coupled subsystems (Braille averaging, performance governance, viewer-content rendering) with dense logic in averaging and composition functions. The heterogeneous nature of edits—mixing algorithm refactoring, control-flow logic, state caching, and test infrastructure—demands reasoning about interaction patterns across multiple domains. Fixture digest changes require validation against observable rendering behavior.\n\n---\n\n## Possibly related PRs\n\n- [flyingrobots/jedit#106](https://github.com/flyingrobots/jedit/pull/106): Directly related—continues the same title-scene performance pipeline, touching identical code paths in `viewer-content.ts`, `title-scene-performance-governor.ts`, `averaging-braille-canvas.ts`, and `title-screen.ts`.\n- [flyingrobots/jedit#97](https://github.com/flyingrobots/jedit/pull/97): The startup title-scene performance governor introduced here is the foundation for this PR's frozen-backdrop reuse logic during intro scenes.\n\n---\n\n## Poem\n\n> 🎬 Braille cells now know their active souls, \n> Frozen backdrops grace the intro's stroll, \n> Presentation surfaces cache and compose, \n> While bunny cameras flip their Z's— \n> A symphony of rendering flows! ✨\n\n\n\n\n

\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Force a live trace after leaving the intro**\n\nWhen the intro frame has already been retained and the first post-intro idle frame is still over budget, this branch now reuses that frozen intro surface indefinitely because the cache age no longer forces a live retrace. That cached surface was rendered with `suppressPresentation: false` in `renderLiveTitleBackdrop`, while idle title frames need `suppressPresentation: true`, so the title/presentation overlay can remain stuck until another cache identity input such as camera, theme, or size changes.\n\nUseful? React with 👍 / 👎.\nUpdate after title intro FPS observation:\\n\\n- Decoupled startup presentation logos from the ray-traced title backdrop. The app now renders backdrop-only content for the title cache and paints the animated intro logos onto a reusable frame surface.\\n- Allowed intro-logo frames to reuse a frozen low-rate backdrop once a slow live trace establishes the backdrop is over budget.\\n- Added regression coverage proving the intro logo animation does not retrace the backdrop and does not mutate the cached backdrop surface.\\n\\nValidation:\\n\\n- `npm run build`\\n- `JEDIT_DIST_PREBUILT=1 node --test spec/workspace-title-performance-governor.spec.mjs spec/title-scene-neon-dispersion.spec.mjs`\\n- `JEDIT_DIST_PREBUILT=1 node --test spec/title-screen.spec.mjs spec/workspace-title-screen.spec.mjs`\\n- `npm run quality`\\n- `git diff --check`\nUpdate after object halo observation:\\n\\n- Root cause: Braille cell collapse averaged active object sample backgrounds into the whole cell background. Title object samples use a near-black surface background, so silhouette cells with mixed object/background subpixels produced dark rectangular halos.\\n- Fix: Braille collapse now averages foreground from active dots and background from inactive dots, with a full-cell fallback for all-active cells.\\n- Added a regression where one active red dot with black active background and seven bright inactive samples must render on the bright inactive background.\\n- Updated the compact visual witness color digests; glyph rows are unchanged, only intended colors changed.\\n\\nValidation:\\n\\n- `npm run build`\\n- `JEDIT_DIST_PREBUILT=1 node --test spec/title-screen.spec.mjs spec/title-scene-render.spec.mjs spec/title-scene-neon-dispersion.spec.mjs`\\n- `JEDIT_DIST_PREBUILT=1 node --test spec/workspace-title-performance-governor.spec.mjs spec/workspace-title-screen.spec.mjs`\\n- `JEDIT_DIST_PREBUILT=1 npm run ci:shard -- title-rendering`\\n- `npm run quality`\\n- `git diff --check`\n_⚠️ Potential issue_ | _🟠 Major_ | _⚡ Quick win_\n\n**Replace inline numeric literals with named constants in this new test block.**\n\nLine 81, Line 82, Line 87, and Line 92 introduce magic numbers directly in core assertions/fixtures.

\n\n\n@codex follow-up for the visual regression James spotted after the no-halo fix.\n\nThe prior change fixed dark mixed-cell silhouettes, but all-active Braille cells fell back to foreground color for their background. That made object interiors render as solid blocks next to textured edge cells, which showed up as strange cube corners.\n\nUpdate: `076f8e4 Fix: preserve Braille fill texture` keeps mixed-cell backgrounds sourced from inactive samples while fully covered cells preserve the active samples' authored backgrounds.\n\nValidation:\n- `npm run build && JEDIT_DIST_PREBUILT=1 node --test spec/title-screen.spec.mjs spec/title-scene-render.spec.mjs spec/title-scene-neon-dispersion.spec.mjs`\n- `JEDIT_DIST_PREBUILT=1 npm run ci:shard -- title-rendering`\n- `npm run quality && git diff --check`\n**Summary**\n* Hoisted the Braille visual-regression sample colors and glyph into named constants, then reused them in both the mixed-cell and all-active-cell assertions so the review fixture intent is explicit without inline literals. [spec/title-screen.spec.mjsL40-L45](https://github.com/flyingrobots/jedit/blob/076f8e455ce087f64c0b395165be0f7634e57645/spec/title-screen.spec.mjs#L40-L45) [spec/title-screen.spec.mjsL77-L108](https://github.com/flyingrobots/jedit/blob/076f8e455ce087f64c0b395165be0f7634e57645/spec/title-screen.spec.mjs#L77-L108)\n* Renamed the startup title-scene governor spec so the test name now matches the asserted low-rate frozen-backdrop posture with ray tracing disabled. [spec/workspace-title-performance-governor.spec.mjsL15-L38](https://github.com/flyingrobots/jedit/blob/076f8e455ce087f64c0b395165be0f7634e57645/spec/workspace-title-performance-governor.spec.mjs#L15-L38)\n* Committed the follow-up as `81d8458 Fix: address title rendering review nits` and created the follow-up PR record.\n\n**Testing**\n* ⚠️ `npm run build && JEDIT_DIST_PREBUILT=1 node --test spec/title-screen.spec.mjs spec/title-scene-render.spec.mjs spec/title-scene-neon-dispersion.spec.mjs` — blocked because the build tried to install `wesley-cli` and the environment could not download from crates.io (`CONNECT tunnel failed, response 403`), leaving `dist/main.js` unavailable.\n* ⚠️ `JEDIT_DIST_PREBUILT=1 node --test spec/title-screen.spec.mjs spec/title-scene-render.spec.mjs spec/title-scene-neon-dispersion.spec.mjs` — blocked because `dist/main.js` is missing after the build limitation.\n* ⚠️ `JEDIT_DIST_PREBUILT=1 npm run ci:shard -- title-rendering` — blocked because

That cached surface was rendered with `suppressPresentation: false` in `renderLiveTitleBackdrop`, while idle title frames need `suppressPresentation: true`, so the title/presentation overlay can remain stuck until another cache identity input such as camera, theme, or size changes.\n\nUseful?
