* Environment prereqs passed for `.spec_system`, `jq`, and `git`; monorepo package checks were skipped by the analyzer because this repo is not currently classified as a monorepo.
* Session source evidence was read from the phase stub and active spec. Required prior Sessions 03, 04, and 06 are marked complete in analyzer output.
* Current source evidence shows the main refactor targets are broad: `renderer.ts` is 1792 lines, `effects.ts` is 1057 lines, `render-model.ts` is 1081 lines, and `runtime-canvas.tsx` is 1177 lines.

**Files Changed**:

* Command/check: `sed -n '1,260p' .spec_system/specs/phase35-session07-renderer-and-react-bridge-refactor/spec.md`
  * Result: PASS - Active spec was readable and matched Session 07 refactor scope.
  * Evidence: Spec listed renderer, effects, render-model, audio adapter, and React bridge extraction as the MVP.
* Command/check: `sed -n '1,260p' .spec_system/PRD/phase_35/session_07_renderer_and_react_bridge_refactor.md`
  * Result: PASS - Phase stub was readable and aligned with the active spec.
  * Evidence: Stub scoped renderer/controller, runtime canvas, effects, and render-model ownership rows to this session.

### Task T019 - Create RuntimeCanvas persistence actions hook

**Started**: 2026-06-26 23:10 **Completed**: 2026-06-26 23:12 **Duration**: 2 minutes

**Notes**:

* Added `use-runtime-persistence-actions.ts` for reset, save, load, restart, completion refs, duplicate reset prevention, in-flight save/load state, durable save hydration, and error mapping.
* Updated `runtime-canvas.tsx` to delegate persistence actions to the hook.
* RuntimeCanvas durable load, invalid load, failed load, reset, and status tests remain green.

**Files Changed**:

* `src/extensions/ai-rogue/views/runtime/use-runtime-persistence-actions.ts` - Added persistence action hook.
* `src/extensions/ai-rogue/views/runtime-canvas.tsx` - Removed inline persistence action implementations and used the hook.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - RuntimeCanvas behavior passed after persistence hook extraction.
  * Evidence: 1 test file passed, 16 tests passed.
* UI product-surface check: PASS - Product-facing runtime error and hidden diagnostics tests remain green.
* UI craft check: N/A - Persistence logic extraction did not change visible layout.

**BQC Fixes**:

* Duplicate action prevention: Reset still guards on `resetPromiseRef`; save/load remain guarded by busy and persistence flags in the extracted hook.
* Failure path completeness: Save/load/reset errors still map to product-facing runtime status or event summary messages.

### Task T020 - Extract RuntimeCanvas controls, panels, compact controls, and assistive helpers

**Started**: 2026-06-26 23:12 **Completed**: 2026-06-26 23:17 **Duration**: 5 minutes

**Notes**:

* Added focused RuntimeCanvas UI modules for primary controls, compile/terminal decision panels, and compact touch controls.
* Kept event summary, render summary, error formatting, and assistive summary helpers in `runtime-assistive-summary.ts`.
* Updated `runtime-canvas.tsx` to delegate control and panel rendering to the extracted modules while preserving product-facing labels and hidden diagnostics.

**Files Changed**:

* `src/extensions/ai-rogue/views/runtime/runtime-controls.tsx` - Added primary runtime controls component.
* `src/extensions/ai-rogue/views/runtime/runtime-decision-panels.tsx` - Added compile and terminal decision panel component.
* `src/extensions/ai-rogue/views/runtime/compact-runtime-controls.tsx` - Added compact directional/action control component.
* `src/extensions/ai-rogue/views/runtime/runtime-assistive-summary.ts` - Used as the shared assistive summary helper owner.
* `src/extensions/ai-rogue/views/runtime-canvas.tsx` - Replaced inline control and panel JSX with extracted components.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - RuntimeCanvas behavior passed after UI component extraction.
  * Evidence: 1 test file passed, 16 tests passed.
* UI product-surface check: PASS - RuntimeCanvas hidden diagnostics and assistive summary tests remain green.
* UI craft check: PASS - Existing compact controls and decision controls remain covered without exposing implementation-only text.

**BQC Fixes**:

* Product surface discipline: Control and decision copy stayed product-facing while internal diagnostics remain hidden.
* Interaction preservation: Extracted controls still route through the existing busy/in-flight guards and controller actions.

**Notes**:

* Ran the required AI Rogue runtime package and client test command.
* Updated import-boundary characterization to reflect the intended React bridge extraction: the mounted runtime lazy import now belongs to `views/runtime/use-runtime-controller.ts`, while `runtime-canvas.tsx` remains the exported view component.
* Updated fixture-boundary characterization to reflect that local combat scenario fixture access moved with renderer state ownership into `renderer-state.ts`.

  * Result: PASS - AI Rogue runtime package and client tests passed.
  * Evidence: 37 test files passed, 257 tests passed.
* UI product-surface check: PASS - RuntimeCanvas and client tests preserved product-facing runtime route behavior.
* UI craft check: PASS - RuntimeCanvas accessibility and compact-control behavior remained covered in the package/client suite.

**BQC Fixes**:

* Contract alignment: Boundary tests now verify the hook-owned mounted runtime import without allowing the broad runtime barrel.

**Verification**:

* Command/check: `bun run typecheck && bun run lint && bun run format:check`
  * Result: PASS - TypeScript, ESLint, and Prettier checks passed.
  * Evidence: `tsc --noEmit` completed, `eslint .` completed, and `prettier --check .` reported all matched files use Prettier code style.
* UI product-surface check: N/A - Static quality gate task only.

### Task T003 - Capture baseline file sizes, import graph, hidden diagnostics, and route cleanup evidence

**Started**: 2026-06-26 22:35 **Completed**: 2026-06-26 22:36 **Duration**: 1 minute

**Notes**:

* Captured baseline line counts for renderer, effects, render-model, runtime bridge, relevant unit tests, and browser specs before extraction.
* Captured import graph evidence showing the public runtime barrel remains narrow through `runtime/mount.ts`, while tests and view code import concrete owners directly.
* Confirmed runtime diagnostics are rendered inside a hidden `dl` with `aria-hidden="true"` and `hidden`, preserving product-surface discipline.
* Confirmed route-cleanup evidence exists in runtime and mobile e2e specs: leaving Play removes `[data-ai-rogue-runtime-canvas]`, and returning remounts a single painted canvas.

**Files Changed**:

* `.spec_system/specs/phase35-session07-renderer-and-react-bridge-refactor/implementation-notes.md` - Added baseline source, import, hidden diagnostics, and route cleanup evidence.

**Verification**:

* Command/check: `wc -l src/extensions/ai-rogue/runtime/renderer.ts src/extensions/ai-rogue/runtime/effects.ts src/extensions/ai-rogue/runtime/render-model.ts src/extensions/ai-rogue/views/runtime-canvas.tsx src/extensions/ai-rogue/runtime/audio.ts src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts src/extensions/ai-rogue/runtime/__tests__/audio.test.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx tests/e2e/ai-rogue-runtime.spec.ts tests/e2e/ai-rogue-mobile.spec.ts`
  * Result: PASS - Baseline sizes captured.
  * Evidence: Runtime target sizes were renderer 1792, effects 1057, render-model 1081, runtime-canvas 1177, and audio 476 lines.
* Command/check: `rg -n "from \"\\./renderer|from \"\\./effects|from \"\\./render-model|from \"../runtime/mount|runtime-canvas|mountAiRogueRenderer|createAiRogueEffects|createAiRogueRenderModel|createAiRogueRenderProjectionCache" src/extensions/ai-rogue tests/e2e | head -200`
  * Result: PASS - Import graph captured.
  * Evidence: `runtime/mount.ts` lazy-imports `./renderer`, `runtime/index.ts` remains the public boundary, and tests import concrete render-model/renderer owners.
* Command/check: `sed -n '910,938p' src/extensions/ai-rogue/views/runtime-canvas.tsx`
  * Result: PASS - Runtime event diagnostics remain hidden from normal product UI.
  * Evidence: `data-ai-rogue-runtime-events` has both `aria-hidden="true"` and `hidden`.
* Command/check: `sed -n '217,232p' tests/e2e/ai-rogue-runtime.spec.ts && sed -n '141,149p' tests/e2e/ai-rogue-mobile.spec.ts`
  * Result: PASS - Browser cleanup evidence exists.
  * Evidence: Runtime spec asserts canvas count becomes 0 on Ledger route and returns to 1 after remount; mobile spec asserts route exit removes the canvas.
* UI product-surface check: PASS - Inspected hidden diagnostics markup in `runtime-canvas.tsx`; event telemetry remains hidden from normal Play UI.
* UI craft check: N/A - Evidence-only task; no UI changed.

**BQC Fixes**:

* None.

* The ledger is ASCII-only Markdown and uses LF line endings through the repository patch workflow.

**Files Changed**:

* `.spec_system/specs/phase35-session07-renderer-and-react-bridge-refactor/implementation-notes.md` - Added the implementation evidence ledger and T002 evidence.

**Verification**:

* Command/check: `test -f .spec_system/specs/phase35-session07-renderer-and-react-bridge-refactor/implementation-notes.md`
  * Result: PASS - Implementation notes file exists.
  * Evidence: File was created at the active session path.
