***

### Task T004 - Inventory current AI Rogue test seams against audit findings

**Started**: 2026-06-26 01:40 **Completed**: 2026-06-26 01:43 **Duration**: 3 minutes

**Notes**:

* Inventoried target files for Session 01 characterization.
* Existing `status-expanded.test.ts` covers status mechanics but not lethal turn-start command-family behavior from AR-D2-001.
* Existing `render-model.test.ts` covers summary generation but not movement-driven summary deltas tied to mounted assistive surfaces from AR-D6-001.
* Existing `runtime-canvas.test.tsx` covers mount, compact actions, compile/terminal decisions, and input-mode updates; it does not expose render-model summary text through the mounted bridge.
* Existing `persistence.test.ts` covers idempotent claims and save slots but not direct oversized claim wallet/ledger drift from AR-D5-001.
* Existing `save-schema.test.ts` covers durable defaults, legacy snapshots, safe text rejection, and run summaries; it does not directly characterize durable saved-run conversion from AR-D5-002.
* Renderer `syncSprites` hides inactive sprites instead of destroying/removing them, giving AR-D4-001 a narrow lifecycle seam for mocked characterization.

**Files Changed**:

* `.spec_system/specs/phase34-session01-characterization-test-harness/implementation-notes.md` - Recorded target seam inventory and audit mapping.

**Verification**:

* Command/check: `sed -n '1,260p' src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts`
  * Result: PASS - Status test seam inspected.
  * Evidence: File has status mechanics tests but no lethal turn-start command-family matrix.

  * Result: PASS - Render-model test seam inspected.
  * Evidence: File has projection and summary assertions but no movement-driven summary delta test.
* Command/check: `sed -n '1,900p' src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Mounted bridge seam inspected.
  * Evidence: File covers mounted controller interactions but no assistive runtime summary propagation.
* Command/check: `sed -n '1,760p' src/extensions/ai-rogue/__tests__/persistence.test.ts && sed -n '1,760p' src/extensions/ai-rogue/__tests__/save-schema.test.ts`
  * Result: PASS - Persistence and schema seams inspected.
  * Evidence: Files cover existing durable writes but not direct oversized claims or durable-to-runtime conversion.
* Command/check: `rg -n "feedback:|spritePool|syncSprites" src/extensions/ai-rogue/runtime/render-model.ts src/extensions/ai-rogue/runtime/renderer.ts`
  * Result: PASS - Renderer feedback retention seam located.
  * Evidence: `projectFeedback` creates `feedback:*` ids and `syncSprites` hides inactive sprites without deletion.
* UI product-surface check: N/A - Inventory changed no user-facing route.
* UI craft check: N/A - Inventory changed no UI.

### Task T005 - Add deterministic lethal turn-start status fixture helpers for Movement, Strike, Surge, and Protocol command setup

**Started**: 2026-06-26 01:43 **Completed**: 2026-06-26 01:44 **Duration**: 1 minute

**Notes**:

* Added `createLethalTurnStartState` in the status-expanded suite.
* The helper uses a fixed row world, fixed seed, 1 player health, 10 shards, a burning status tick, right-facing player state, and one carried Patch Kit protocol.
* The setup supports Movement, Strike, Surge, and Protocol command-family characterization without random or browser-only setup.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts` - Added deterministic lethal turn-start fixture helper and command type imports.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts`
  * Result: PASS - Status-expanded suite passed with the new fixture helper.
  * Evidence: Vitest reported 1 test file passed and 8 tests passed in 285ms.
* Command/check: Targeted inspection of `createLethalTurnStartState`
  * Result: PASS - Helper uses deterministic rows, seed, status, shards, and protocol setup.
  * Evidence: Fixture creates a bounded local world through `createAiRogueWorldFromRows`.
* UI product-surface check: N/A - Unit test helper changed no user-facing route.
* UI craft check: N/A - Unit test helper changed no UI.

### Task T006 - Add runtime canvas snapshot helper support for movement-driven summary updates and assistive-surface assertions

**Started**: 2026-06-26 01:44 **Completed**: 2026-06-26 01:45 **Duration**: 1 minute

**Notes**:

* Added `createRuntimeRunSnapshot` so runtime-canvas tests can use complete simulation-shaped run snapshots.
* Updated `createRuntimeSnapshot` to compose real run snapshots with focused bridge overrides for compile, terminal, and movement/update cases.
* This avoids relying on partial run casts when later tests inspect mounted bridge state.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Added real simulation-backed runtime snapshot helper support.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Existing runtime-canvas bridge tests still pass with complete run-shaped snapshots.
  * Evidence: Vitest reported 1 test file passed and 5 tests passed in 795ms.
* Command/check: Targeted inspection of `createRuntimeRunSnapshot`
  * Result: PASS - Helper builds snapshots through `createAiRogueRun` and `createAiRogueWorldFromRows`.
  * Evidence: Runtime-canvas tests now use a deterministic `#####/#@.>#/#####` world snapshot.
* UI product-surface check: N/A - Test helper changed no user-facing route.
* UI craft check: N/A - Test helper changed no UI.

***

### Task T007 - Create a mocked renderer lifecycle test harness for sprite pool and transient feedback descriptor characterization

**Started**: 2026-06-26 01:45 **Completed**: 2026-06-26 01:46 **Duration**: 1 minute

**Notes**:

* Added a renderer lifecycle characterization file that uses render-model feedback descriptors and mocked sprite objects.
* Added a narrow internal renderer test seam, `__aiRogueHideInactiveSpritesForTest`, around the existing inactive-sprite hiding behavior.
* Current behavior is documented: active feedback descriptors are bounded to the latest five, but older `feedback:*` sprites remain retained in the pool and are hidden rather than destroyed.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/renderer.ts` - Extracted inactive sprite hiding into a pure helper and exported a direct test seam.
* `src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts` - Added mocked feedback sprite lifecycle characterization.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`
  * Result: PASS - Renderer lifecycle characterization passed.
  * Evidence: Vitest reported 1 test file passed and 1 test passed in 335ms.
* Command/check: Targeted inspection of renderer helper call path
  * Result: PASS - `syncSprites` still creates/updates active sprites and delegates only inactive visibility changes to the extracted helper.
  * Evidence: Runtime behavior remains hide-inactive, not destroy/remove.
* UI product-surface check: N/A - Renderer test seam changed no user-facing route or visible diagnostics.
* UI craft check: N/A - Unit test seam changed no UI.

**BQC Fixes**:

* Resource cleanup: Added characterization evidence for retained hidden `feedback:*` sprites so Session 04 can fix cleanup against a repeatable target (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`).

***

### Task T008 - Add or isolate durable claim and saved-run fixture helpers for oversized claim and runtime snapshot cases

**Started**: 2026-06-26 01:46 **Completed**: 2026-06-26 01:47 **Duration**: 1 minute

**Notes**:

* Added `createOversizedClaim` to centralize direct AR-D5-001 oversized claim setup.
* Added `createRuntimeSaveSnapshot` to replace the large inline saved-run fixture with a real simulation-backed run state.
* Existing persistence save-slot coverage still validates through `createAiRogueRuntimeSaveSlot`.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/persistence.test.ts` - Added oversized claim and runtime save snapshot helpers; replaced an inline saved-run fixture with the helper.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/persistence.test.ts`
  * Result: PASS - Persistence suite passed after helper isolation.
  * Evidence: Vitest reported 1 test file passed and 13 tests passed in 498ms.
* Command/check: Targeted inspection of `createRuntimeSaveSnapshot`
  * Result: PASS - Helper builds a deterministic run through `createAiRogueRun` and keeps save-slot schema validation in the existing test path.
  * Evidence: Save-slot test still writes a `ready` slot through `putAiRogueSaveSlot`.
* UI product-surface check: N/A - Test helper changed no user-facing route.
* UI craft check: N/A - Test helper changed no UI.

***

### Task T009 - Add lethal DOT command matrix assertions across Movement, Strike, Surge, and Protocol with exact event and status expectations

**Started**: 2026-06-26 01:43 **Completed**: 2026-06-26 01:48 **Duration**: 5 minutes

**Notes**:

* Added AR-D2-001 command-family assertions for lethal turn-start burning.
* Current behavior is explicit:
  * Movement and Strike return `lost` with only `status` and `loss` events.
  * Surge still spends shards, attacks, then returns `lost`.
  * Patch Kit Protocol still resolves after lethal status damage and returns `active`.
* These are current-behavior assertions for later Session 03 remediation.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts` - Added lethal DOT command matrix assertions for Movement, Strike, Surge, and Protocol.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts`
  * Result: PASS - Status-expanded suite passed with the new matrix assertions.
  * Evidence: Vitest reported 1 test file passed and 8 tests passed in 285ms.
* Command/check: Targeted assertion review for AR-D2-001
  * Result: PASS - Test checks status, player health, shard spend, enemy damage, protocol consumption, and event type order.
  * Evidence: Matrix distinguishes guarded Movement/Strike from currently unguarded Surge/Protocol behavior.
* UI product-surface check: N/A - Unit tests changed no user-facing route.
* UI craft check: N/A - Unit tests changed no UI.

**BQC Fixes**:

* Contract alignment: The test records command-family status/event contracts so later simulation changes must align across Movement, Strike, Surge, and Protocol (`src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts`).

***

### Task T010 - Add render summary characterization proving rich summary text changes with runtime state

**Started**: 2026-06-26 01:48 **Completed**: 2026-06-26 01:48 **Duration**: 1 minute

**Notes**:

* Added AR-D6-001 source-layer characterization for `createAiRogueRenderModel`.
* The test proves summary text changes after a deterministic movement turn and runtime preference change.
* This isolates render-model summary generation from the mounted bridge exposure gap covered by T011.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` - Added summary delta characterization for turn, motion, contrast, and input-mode text.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts`
  * Result: PASS - Render-model suite passed with the new summary delta assertion.
  * Evidence: Vitest reported 1 test file passed and 6 tests passed in 287ms.
* Command/check: Targeted assertion review for summary content
  * Result: PASS - Test checks before/after text, `turn 0`, `turn 1`, standard/keyboard modes, and reduced/high-contrast/compact modes.
  * Evidence: Render-model rich summary changes independently of React bridge exposure.
* UI product-surface check: N/A - Unit tests changed no user-facing route.
* UI craft check: N/A - Unit tests changed no UI.

**BQC Fixes**:

* Contract alignment: The test locks summary content at the render-model boundary before accessibility bridge work changes how the summary is surfaced (`src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts`).

***

### Task T011 - Add mounted runtime summary propagation characterization with loading, ready, update, and unmount cleanup states

**Started**: 2026-06-26 01:48 **Completed**: 2026-06-26 01:49 **Duration**: 1 minute

**Notes**:

* Added AR-D6-001 mounted bridge characterization in `runtime-canvas.test.tsx`.
* The test verifies loading state, ready state, movement snapshot update, live status text, and unmount cleanup.
* Current behavior is explicit: the rich render-model summary for the moved snapshot is not present in the mounted DOM or assistive live text.
* This is a current-behavior assertion for Session 02 accessibility remediation.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Added simulation-backed mounted summary exposure and cleanup characterization.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Runtime-canvas bridge suite passed with the mounted summary characterization.
  * Evidence: Vitest reported 1 test file passed and 6 tests passed in 850ms.
* Command/check: Targeted assertion review for AR-D6-001
  * Result: PASS - Test checks loading, ready, running update, `Runtime running / saves empty`, absence of rich `turn 1` summary text, and `destroy` on unmount.
  * Evidence: Bridge updates coarse status but does not expose render-model summary text.
* UI product-surface check: PASS - Component rendered in happy-dom; no debug/runtime diagnostics or new product-visible text were added to implementation code.
* UI craft check: N/A - Test-only change; no rendered UI styling changed.

**BQC Fixes**:

* Resource cleanup: Added unmount assertion that the mocked runtime controller is destroyed (`src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`).
* Accessibility and platform compliance: Added characterization showing the current dynamic summary exposure gap before remediation (`src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`).

***

### Task T012 - Add transient feedback sprite retention characterization with bounded data, mocked Pixi objects, and cleanup expectations

**Started**: 2026-06-26 01:45 **Completed**: 2026-06-26 01:50 **Duration**: 5 minutes

**Notes**:

* Added AR-D4-001 transient sprite retention characterization.
* The test creates bounded feedback descriptors from render-model output and mocked sprite objects with destroy spies.
* Current behavior is explicit: after eight feedback events, only five descriptors are active, but eight `feedback:*` sprite ids remain retained and the inactive three are hidden without `destroy`.
* This is a current-behavior assertion for Session 04 renderer lifecycle remediation.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts` - Added transient feedback sprite retention characterization.
* `src/extensions/ai-rogue/runtime/renderer.ts` - Added the narrow inactive-sprite visibility test seam used by the characterization.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`
  * Result: PASS - Renderer lifecycle characterization passed.
  * Evidence: Vitest reported 1 test file passed and 1 test passed in 335ms.
* Command/check: Targeted assertion review for AR-D4-001
  * Result: PASS - Test checks five active feedback descriptors, eight retained feedback ids, hidden inactive ids, and no destroy calls for hidden feedback sprites.
  * Evidence: The current retention pressure is repeatable without WebGL.
* UI product-surface check: N/A - Unit tests changed no user-facing route.
* UI craft check: N/A - Unit tests changed no UI.

**BQC Fixes**:

* Resource cleanup: Added explicit retained-hidden-sprite evidence for future cleanup remediation (`src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts`).

***

### Task T013 - Add direct oversized claim characterization for wallet, ledger amount, and balanceAfter behavior

**Started**: 2026-06-26 01:50 **Completed**: 2026-06-26 01:50 **Duration**: 1 minute

**Notes**:

* Added AR-D5-001 direct claim characterization for an oversized 250-shard claim.
* Current behavior is explicit: wallet balance and ledger `balanceAfter` cap at 100, while the ledger entry amount remains 250.
* This is a current-behavior assertion for Session 06 schema/persistence remediation.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/persistence.test.ts` - Added oversized direct claim characterization using the shared helper.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/persistence.test.ts`
  * Result: PASS - Persistence suite passed with the oversized claim characterization.
  * Evidence: Vitest reported 1 test file passed and 14 tests passed in 526ms.
* Command/check: Targeted assertion review for AR-D5-001
  * Result: PASS - Test checks result wallet balance 100, entry amount 250, entry balanceAfter 100, persisted ledger amount 250, and adapter wallet balance 100.
  * Evidence: Wallet and ledger amount drift is now explicitly visible.
* UI product-surface check: N/A - Unit tests changed no user-facing route.
* UI craft check: N/A - Unit tests changed no UI.

**BQC Fixes**:

* Trust boundary enforcement: Added direct exported-helper input characterization for oversized claim validation drift (`src/extensions/ai-rogue/__tests__/persistence.test.ts`).
* Contract alignment: Added wallet/ledger amount assertions for direct claim writes (`src/extensions/ai-rogue/__tests__/persistence.test.ts`).

***

### Task T014 - Add durable snapshot and saved-run conversion characterization with schema-validated input and browser-safe text rejection

**Started**: 2026-06-26 01:50 **Completed**: 2026-06-26 01:51 **Duration**: 1 minute

**Notes**:

* Added AR-D5-002 durable saved-run schema characterization.
* The test parses a schema-valid ready runtime snapshot with real simulation state.
* The test also rejects unsafe persisted summary text before it can become a saved-run record.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/save-schema.test.ts` - Added durable runtime snapshot validation and unsafe text rejection characterization.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/save-schema.test.ts`
  * Result: PASS - Save-schema suite passed with the durable saved-run characterization.
  * Evidence: Vitest reported 1 test file passed and 13 tests passed in 368ms.
* Command/check: Targeted assertion review for AR-D5-002

**Started**: 2026-06-26 01:51 **Completed**: 2026-06-26 01:52 **Duration**: 1 minute

**Notes**:

* Added AR-D5-002 runtime bridge save/load characterization through the component Load control.
* The test feeds a durable runtime snapshot through `onLoadRuntimeSnapshot` and asserts the payload passed to `controller.load`.
* Current behavior is explicit: the bridge derives live payload fields from durable `runState` and metadata while relying on the current private conversion/cast seam.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Added durable saved-run load bridge characterization and durable snapshot fixture helper.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Runtime-canvas bridge suite passed with the save/load conversion characterization.

### Task T018 - Identify Playwright AI Rogue scenarios for later sessions

**Started**: 2026-06-26 01:53 **Completed**: 2026-06-26 01:54 **Duration**: 1 minute

**Notes**:

* Reviewed existing AI Rogue Playwright coverage and recorded later-session mapping.
* No e2e files were changed in this characterization session.
* Later e2e mapping:
  * AR-D6-001 / Session 02: extend `tests/e2e/ai-rogue-runtime.spec.ts` to assert a dynamic assistive runtime summary after movement once the DOM/live-region behavior exists.
  * AR-D6-002 / Session 02: extend `tests/e2e/ai-rogue-mobile.spec.ts` for compact Inspect and Next target controls once those controls are implemented.
  * AR-D1-002 and AR-D2-001 / Session 03: update the scripted combat e2e hook in `tests/e2e/ai-rogue-runtime.spec.ts` if `scenario=combat` is removed or gated behind a test-only route.
  * AR-D4-001 / Session 04: keep unit lifecycle coverage primary; add a long-run browser retention smoke only if renderer cleanup changes need canvas-level proof.
  * AR-D5-002 / Session 06: existing `AI Rogue runtime saves, resets, and loads deterministic runs` e2e should remain the browser-level save/load proof after schema helper remediation.
  * Public demo / closeout: keep `tests/e2e/pages-demo-mobile.spec.ts` route matrix coverage for no local bridge requests and mobile no-overflow.

**Files Changed**:

* `.spec_system/specs/phase34-session01-characterization-test-harness/implementation-notes.md` - Recorded e2e follow-up mapping.

**Verification**:

* Command/check: `sed -n '1,260p' tests/e2e/ai-rogue-runtime.spec.ts`
  * Result: PASS - Runtime e2e scenarios inspected.
  * Evidence: Existing coverage includes canvas mount, resize/input, movement/pause, seed replay, save/reset/load, scripted combat, and route cleanup.
* Command/check: `sed -n '1,260p' tests/e2e/ai-rogue-mobile.spec.ts && sed -n '1,260p' tests/e2e/ai-rogue-persistence.spec.ts`
  * Result: PASS - Mobile and persistence e2e scenarios inspected.
  * Evidence: Existing coverage includes compact controls, mobile layout, reduced-motion route cleanup, preferences, claims, save readiness, loadout, purchases, and reset.
* Command/check: `rg -n "AI Rogue|runtime|compact|save|load|scenario|aria|access|canvas|mobile" tests/e2e/ai-rogue-*.spec.ts tests/e2e/pages-demo-mobile.spec.ts`
  * Result: PASS - Relevant browser coverage surfaces identified.
  * Evidence: Mapping above is based on current e2e spec coverage.
* UI product-surface check: N/A - E2E mapping changed no user-facing route.
* UI craft check: N/A - E2E mapping changed no UI.

### Task T019 - Run TypeScript validation for production test seam and type imports

**Started**: 2026-06-26 01:54 **Completed**: 2026-06-26 01:55 **Duration**: 1 minute

**Notes**:

* Ran project TypeScript validation because this session added a production renderer test seam and several typed test fixtures.

**Files Changed**:

* `.spec_system/specs/phase34-session01-characterization-test-harness/implementation-notes.md` - Recorded TypeScript gate evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript project validation passed.
  * Evidence: `tsc --noEmit` exited 0.
* UI product-surface check: N/A - Typecheck changed no user-facing route.
* UI craft check: N/A - Typecheck changed no UI.

### Task T020 - Validate ASCII/LF requirements, update coverage notes, and confirm no product-facing diagnostics were added

**Started**: 2026-06-26 01:55 **Completed**: 2026-06-26 01:55 **Duration**: 1 minute

**Notes**:

* Ran ASCII and CRLF checks on all files changed by this session.
* Ran whitespace validation on the session diff for changed files.
* Confirmed no user-facing route or view files under `src/extensions/ai-rogue/views`, `src/routes`, or `src/components` were changed.
* Added the final finding-to-test coverage map and handoff caveats below.

**Files Changed**:

* `.spec_system/specs/phase34-session01-characterization-test-harness/implementation-notes.md` - Added final checks, coverage map, and handoff notes.
* `.spec_system/specs/phase34-session01-characterization-test-harness/tasks.md` - Marked final task and completion checklist complete.

**Verification**:

* Command/check: `perl -ne 'print "$ARGV:$.:$_" if /[^\x00-\x7F]/' [changed files]`
  * Result: PASS - No non-ASCII output reported.
  * Evidence: Command exited 0 with no output.
* Command/check: `perl -ne 'print "$ARGV:$.:CRLF\n" if /\r/' [changed files]`
  * Result: PASS - No CRLF output reported.
  * Evidence: Command exited 0 with no output.
* Command/check: `git diff --check -- [changed files]`
  * Result: PASS - No whitespace errors reported.
  * Evidence: Command exited 0 with no output.
* Command/check: `git diff --name-only -- src/extensions/ai-rogue/views src/routes src/components`
  * Result: PASS - No product route/view/component files changed.
  * Evidence: Command exited 0 with no output.
* UI product-surface check: PASS - No user-facing route, component, or view implementation changed; no diagnostics were added to normal product surfaces.
* UI craft check: N/A - No rendered product UI styling changed.

| AR-D5-002 | `src/extensions/ai-rogue/__tests__/save-schema.test.ts` durable snapshot validation and `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` load bridge conversion     | Durable snapshots parse and load through the bridge, but the private conversion still relies on the current durable-to-live cast seam. |

## Handoff Notes

* No external blockers remain.
* No dependencies, remote services, hosted storage, collectors, or public-demo runtime bridge calls were added.
* AI Rogue remains disabled-first and browser-local.
* User-facing AI Rogue product surfaces were not changed.
* Later sessions should update these characterization assertions when they intentionally fix AR-D2-001, AR-D6-001, AR-D4-001, AR-D5-001, or AR-D5-002.
