### Task T018 - Run Focused AI Rogue Vitest Suite

**Started**: 2026-06-26 05:12 **Completed**: 2026-06-26 05:13 **Duration**: 1 minute

**Notes**:

* Initial AI Rogue suite run failed because `client.test.tsx` still expected the old `import("../runtime")` bridge path.
* Updated the import-boundary assertion to require `import("../runtime/mount")` and reject the old barrel lazy import.
* Reran the focused AI Rogue suite successfully.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/client.test.tsx` - Updated runtime lazy-import boundary assertion to the narrow mounted entrypoint.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded focused AI Rogue suite evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue`
  * Result: PASS - Focused AI Rogue Vitest suite passes after boundary assertion update.
  * Evidence: Vitest reported 45 files passed and 296 tests passed.
* Command/check: Initial `bun run test -- src/extensions/ai-rogue`
  * Result: FAIL then resolved - One stale assertion expected `import("../runtime")`.
  * Evidence: Failure was in `src/extensions/ai-rogue/__tests__/client.test.tsx`; assertion now matches `import("../runtime/mount")` and rerun passed.
* UI product-surface check: PASS - AI Rogue component and bridge tests passed, including product-facing runtime loading/error/offline/status states.
* UI craft check: PASS - AI Rogue component and bridge tests passed, including control state behavior and assistive runtime summary coverage.

**BQC Fixes**:

* Contract alignment: Updated an existing import-boundary test to enforce the new mounted runtime contract instead of the old broad barrel (`src/extensions/ai-rogue/__tests__/client.test.tsx`).

***

### Task T017 - Run Focused Runtime Ownership Coverage

**Started**: 2026-06-26 05:12 **Completed**: 2026-06-26 05:12 **Duration**: 1 minute

**Files Changed**:

* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded focused coverage evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/pre-run-state.test.ts src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts src/extensions/ai-rogue/runtime/__tests__/simulation.test.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Focused ownership coverage passes.
  * Evidence: Vitest reported 4 files passed and 29 tests passed.
* UI product-surface check: PASS - Runtime canvas bridge coverage verifies loading, error, offline, runtime status, and assistive summary copy remained product-facing.
* UI craft check: PASS - Runtime canvas bridge coverage verifies compact/keyboard control states, disabled states, and cleanup behavior remained stable.

***

## Ownership Closeout And Remaining Refactor Prerequisites

* AR-D1-001 status: implemented for pre-run selected-upgrade and progression loadout ownership. Simulation now owns `createAiRogueRun` selected-upgrade options plus `applyAiRoguePreRunSelectedUpgrade` and `applyAiRoguePreRunProgressionLoadout`; renderer/controller code requests those transitions and no-ops after turn 0 or terminal status.
* AR-D1-003 status: implemented for mounted product entrypoints. Product bridge code imports `runtime/mount`; `runtime/index.ts` re-exports only that mounted surface; `simulation-fixtures` and broad internals are not public barrel exports.
* Remaining split prerequisite: `simulation.ts` is still 3222 lines and should be split only after Session 06 persistence contracts and Session 07 render performance/audio gates are complete.
* Remaining split prerequisite: `renderer.ts` is still 1770 lines and should be split after render hot-loop caching, audio fallback documentation, and route smoke evidence are complete in Sessions 07 and 08.
* Remaining split prerequisite: `runtime/types.ts` is still 808 lines and should be split after durable saved-run naming and hydration helpers are handled in Session 06.
* Internal fixture note: `renderer.ts` still directly imports `simulation-fixtures` for the local/test-only combat scenario hook preserved by Session 03; this is not re-exported through product entrypoints.

***

### Task T016 - Record Refactor Prerequisites And AR-D1 Status

**Started**: 2026-06-26 05:11 **Completed**: 2026-06-26 05:12 **Duration**: 1 minute

**Notes**:

* Recorded AR-D1-001 and AR-D1-003 implementation status after code changes.
* Recorded current oversized-module line counts and why full file splits remain deferred to later sessions.
* Documented the remaining internal `simulation-fixtures` renderer import as local/test-only and not public-barrel exposure.

**Files Changed**:

* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Added ownership closeout and remaining refactor prerequisites.

**Verification**:

* Command/check: `wc -l src/extensions/ai-rogue/runtime/simulation.ts src/extensions/ai-rogue/runtime/renderer.ts src/extensions/ai-rogue/runtime/types.ts`
  * Result: PASS - Oversized-module counts captured.
  * Evidence: `simulation.ts` 3222 lines, `renderer.ts` 1770 lines, `types.ts` 808 lines.
* Command/check: `rg -n "applySelectedUpgradeToRun|selectedUpgrade\\.maxHealthBonus|state\\.runState = \\{|simulation-fixtures|export \\* from \\\"\\./simulation\\\"" src/extensions/ai-rogue/runtime/renderer.ts src/extensions/ai-rogue/runtime/index.ts src/extensions/ai-rogue/runtime/mount.ts`
  * Result: PASS - Public boundary and renderer ownership status inspected.
  * Evidence: Only remaining match is the renderer's direct local/test fixture import; no public barrel fixture/internal export or renderer selected-upgrade helper remains.
* UI product-surface check: N/A - Notes-only task; no user-facing surface changed.
* UI craft check: N/A - Notes-only task; no UI changed.

***

### Task T015 - Add Runtime Boundary Tests

**Started**: 2026-06-26 05:10 **Completed**: 2026-06-26 05:11 **Duration**: 1 minute

**Notes**:

* Added static source guards for the runtime public barrel, mounted runtime entrypoint, and product bridge import path.
* Tests prove `simulation-fixtures` and broad internal module re-exports are not exposed through the mounted public entrypoint.
* Tests also prove runtime canvas loads `../runtime/mount` instead of the compatibility barrel.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts` - Added runtime boundary source guards.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded task evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Boundary and bridge coverage pass together.

* Command/check: Targeted test inspection of `runtime-boundary.test.ts`
  * Result: PASS - Guards inspect `runtime/index.ts`, `runtime/mount.ts`, and `views/runtime-canvas.tsx`.
  * Evidence: Assertions reject `simulation-fixtures`, broad runtime exports, and old product bridge barrel imports.
* UI product-surface check: N/A - Static boundary tests only; no rendered product surface changed.
* UI craft check: N/A - Static boundary tests only; no UI layout changed.

**BQC Fixes**:

* Trust boundary enforcement: Added source guards to prevent mounted runtime entrypoints from exposing fixtures or broad simulation internals (`src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts`).

***

### Task T014 - Update Runtime Canvas Mounted Entrypoint Imports

**Started**: 2026-06-26 05:08 **Completed**: 2026-06-26 05:10 **Duration**: 2 minutes

**Notes**:

* Updated runtime canvas type imports and dynamic import to use `../runtime/mount`.
* Updated runtime canvas test mocks and mounted runtime type imports to use `../runtime/mount`.
* Preserved loading, error, offline, unmount, save/load, and input update behavior through the existing bridge test coverage.

**Files Changed**:

* `src/extensions/ai-rogue/views/runtime-canvas.tsx` - Moved mounted runtime imports to the narrow entrypoint.
* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Updated mounted runtime mock and type import path.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded task evidence.

  * Result: PASS - Product bridge uses the narrow mounted entrypoint.
  * Evidence: Only dynamic bridge import match is `import("../runtime/mount")`; test-only internal imports remain direct module imports.
* UI product-surface check: PASS - `runtime-canvas.test.tsx` verifies product-facing loading, error, offline, and runtime status copy remains present and not replaced by implementation diagnostics.
* UI craft check: PASS - Existing bridge tests verify disabled control states, assistive summary, compact/keyboard modes, and cleanup behavior were preserved.

**BQC Fixes**:

* Contract alignment: Runtime canvas now depends on mounted runtime contracts instead of the broad runtime barrel (`src/extensions/ai-rogue/views/runtime-canvas.tsx`).

***

* UI product-surface check: N/A - Renderer ownership cleanup only; no route rendered in this task.
* UI craft check: N/A - Renderer ownership cleanup only; no UI layout changed.

**BQC Fixes**:

* Contract alignment: Removed duplicate selected-upgrade rule implementation from renderer after all renderer call sites used simulation-owned APIs (`src/extensions/ai-rogue/runtime/renderer.ts`).

***

### Task T012 - Replace Controller Progression Loadout Mutation

**Started**: 2026-06-26 05:06 **Completed**: 2026-06-26 05:08 **Duration**: 2 minutes

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/pre-run-state.test.ts` - Added selected-upgrade pre-run ownership tests.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded task evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/pre-run-state.test.ts`
  * Result: PASS - New pre-run state coverage passes.
  * Evidence: Vitest reported 1 file passed and 4 tests passed.
* Command/check: Targeted test inspection for selected-upgrade cases.
  * Result: PASS - Tests cover apply, replace, clear, and repeated apply paths.
  * Evidence: Test cases assert max-health/health deltas against the base run.
* UI product-surface check: N/A - Headless simulation tests only; no user-facing surface changed.
* UI craft check: N/A - Headless simulation tests only; no UI changed.

**BQC Fixes**:

* Contract alignment: Added regression coverage that selected-upgrade state transitions are owned by simulation and cannot double-apply bonuses (`src/extensions/ai-rogue/runtime/__tests__/pre-run-state.test.ts`).

### Task T005 - Add Simulation-Owned Progression Loadout Transition

**Started**: 2026-06-26 05:03 **Completed**: 2026-06-26 05:04 **Duration**: 1 minute

**Notes**:

* Added `applyAiRoguePreRunProgressionLoadout`, guarded to active turn-0 runs.
* The helper recalculates progression resources, runtime objective, and achievement ids whenever loadout changes before turn 0.
* The helper transitions player class stats by removing the current class deltas and applying the next class deltas, preserving selected-upgrade health bonuses.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/simulation.ts` - Added turn-0 loadout transition helper and dependent progression revalidation.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded task evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/simulation.test.ts`
  * Result: PASS - Existing simulation coverage still passes.
  * Evidence: Vitest reported 1 file passed and 11 tests passed.
* Command/check: Targeted source inspection of `applyAiRoguePreRunProgressionLoadout`
  * Result: PASS - Loadout transition recalculates `progressionResources`, `objective`, and `achievementIds`.
  * Evidence: Helper lives in `simulation.ts` and is guarded by active turn-0 state.
* UI product-surface check: N/A - Headless simulation API change only; no user-facing surface changed.
* UI craft check: N/A - Headless simulation API change only; no UI changed.

**BQC Fixes**:

* State freshness on re-entry: Pre-run loadout changes now revalidate derived progression resources, objective, achievements, and player class stats together (`src/extensions/ai-rogue/runtime/simulation.ts`).
* Contract alignment: Loadout state ownership moved from renderer field replacement to simulation-owned transition API (`src/extensions/ai-rogue/runtime/simulation.ts`).

### Task T004 - Add Simulation-Owned Selected-Upgrade Transition

**Started**: 2026-06-26 05:01 **Completed**: 2026-06-26 05:03 **Duration**: 2 minutes

**Notes**:

* Added `selectedUpgrade` to `AiRogueRunOptions` so fresh runs can start from the simulation-owned selected-upgrade contract.
* Added `applyAiRoguePreRunSelectedUpgrade`, guarded to active turn-0 runs, with exhaustive `starting-integrity` handling.
* The helper removes the previous max-health bonus before applying the next one, so apply, replace, clear, and repeated apply paths cannot double-count.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/simulation.ts` - Added selected-upgrade run option, max-health bonus derivation, and turn-0 selected-upgrade transition helper.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded task evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/simulation.test.ts`
  * Result: PASS - Existing simulation coverage still passes.
  * Evidence: Vitest reported 1 file passed and 11 tests passed.
* Command/check: Targeted source inspection of `applyAiRoguePreRunSelectedUpgrade`
  * Result: PASS - Helper is owned by simulation and guarded by `state.status === "active"` and `state.turn === 0`.
  * Evidence: `simulation.ts` now exports the helper and `createAiRogueRun` applies it before snapshot creation.
* UI product-surface check: N/A - Headless simulation API change only; no user-facing surface changed.
* UI craft check: N/A - Headless simulation API change only; no UI changed.

**BQC Fixes**:

* Contract alignment: Selected-upgrade run creation and turn-0 update now share one simulation-owned helper instead of renderer-local game-rule mutation (`src/extensions/ai-rogue/runtime/simulation.ts`).

### Task T003 - Create Implementation Notes Scaffold

**Started**: 2026-06-26 05:00 **Completed**: 2026-06-26 05:00 **Duration**: 1 minute

**Notes**:

* Created the session implementation notes with environment verification, progress metrics, task evidence, boundary decisions, and later gate evidence sections.
* Initialized the log in ASCII Markdown so each completed task can be recorded before its checkbox is marked.

**Files Changed**:

* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Added session scaffold and setup task logs.
* `.spec_system/specs/phase34-session05-runtime-api-ownership/tasks.md` - Updated setup task progress.

**Verification**:

* Command/check: `sed -n '1,180p' .spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md`
  * Result: PASS - Scaffold and setup evidence are present.
  * Evidence: File includes session metadata, progress table, environment checklist, and task log entries.
* UI product-surface check: N/A - Notes scaffold only; no user-facing surface changed.
* UI craft check: N/A - Notes scaffold only; no UI changed.

### Task T002 - Inspect Runtime Mutation And Boundary Paths

**Started**: 2026-06-26 05:00 **Completed**: 2026-06-26 05:00 **Duration**: 2 minutes

**Notes**:

* Found renderer-local selected-upgrade mutation in `applySelectedUpgradeToRun`, including the `starting-integrity` health and max-health bonus rule.
* Found controller `updateProgressionLoadout` directly replacing `state.runState.progressionLoadout` without recalculating progression resources, objective, or achievements.
* Found `runtime/index.ts` re-exporting broad internals and `simulation-fixtures`, while `runtime-canvas.tsx` and its bridge tests import mounted contracts from `../runtime`.
* Confirmed simulation already owns progression class/resource/objective derivation during `createAiRogueRun`, which is the right place to add turn-0 pre-run transitions.

**Files Changed**:

* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Recorded source inspection evidence.

**Verification**:

* Command/check: `rg -n "selectedUpgrade|progressionLoadout|createRuntimeRun|updateSelectedUpgrade|updateProgressionLoadout|applySelected|loadout" src/extensions/ai-rogue/runtime/renderer.ts`
  * Result: PASS - Renderer mutation paths identified.
  * Evidence: Matches showed `applySelectedUpgradeToRun`, `createRuntimeRun`, `updateSelectedUpgrade`, and `updateProgressionLoadout` call sites.
* Command/check: `rg -n "progressionLoadout|selectedUpgrade|createAiRogueRun|createAiRogueSnapshot|resources|achievement|objective" src/extensions/ai-rogue/runtime/simulation.ts`
  * Result: PASS - Simulation derivation points identified.
  * Evidence: Matches showed `createAiRogueRun`, progression resource/objective/achievement derivation, and snapshot fields.
* Command/check: `sed -n '1,220p' src/extensions/ai-rogue/runtime/index.ts`
  * Result: PASS - Runtime barrel boundary inspected.
  * Evidence: Barrel re-exported runtime internals, content modules, `simulation`, and `simulation-fixtures`.
* Command/check: `sed -n '1,240p' src/extensions/ai-rogue/views/runtime-canvas.tsx`
  * Result: PASS - Product bridge import inspected.
  * Evidence: Runtime canvas imports mounted runtime types from `../runtime`.
* UI product-surface check: N/A - Source inspection only; no user-facing surface changed.
* UI craft check: N/A - Source inspection only; no UI changed.

**Started**: 2026-06-26 05:00 **Completed**: 2026-06-26 05:00 **Duration**: 1 minute

**Notes**:

* Confirmed the active session is `phase34-session05-runtime-api-ownership`.
* Confirmed Phase 34 Session 05 maps to AR-D1-001 renderer-local pre-run state mutation and AR-D1-003 broad runtime barrel exports.
* Confirmed Sessions 01 through 04 are already completed in analysis output and Session 05 is the active unfinished candidate.

**Files Changed**:

* `.spec_system/specs/phase34-session05-runtime-api-ownership/implementation-notes.md` - Created implementation log and recorded scope evidence.

**Verification**:

* Command/check: `if [ -d ".spec_system/scripts" ]; then bash .spec_system/scripts/analyze-project.sh --json; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/scripts/analyze-project.sh --json; fi`
  * Result: PASS - Active session resolved.
  * Evidence: Output reported `current_phase` 34, `current_session` `phase34-session05-runtime-api-ownership`, Sessions 01-04 completed, and Session 05 as the first unfinished current-phase candidate.
* Command/check: `sed -n '1,260p' .spec_system/PRD/phase_34/session_05_runtime_api_ownership.md`
  * Result: PASS - Scope and audit evidence inspected.
  * Evidence: Stub lists AR-D1-001 and AR-D1-003 as primary findings and excludes large module splits/default enablement.
* UI product-surface check: N/A - Scope verification only; no user-facing surface changed.
* UI craft check: N/A - Scope verification only; no UI changed.
