### Task T001 - Verify prerequisite evidence, source locations, and current storage caveats

**Started**: 2026-06-26 20:17 **Completed**: 2026-06-26 20:19 **Duration**: 2 minutes

**Notes**:

* Verified deterministic spec-system state before implementation.
* Confirmed current session is `phase35-session05-persistence-schema-contracts` and Sessions 01-04 are complete in analyzer output.
* Confirmed the phase stub routes AR-D5-001, AR-D5-002, and the AR-D8-002 storage coverage portion to this session.
* Confirmed the current storage caveat: blocked or quota IndexedDB browser behavior should be covered where feasible, with an explicit source-inspection caveat only if reliable browser simulation is unstable.
* Confirmed the generic prerequisite checker reports `vitest` and `tsc` as missing because it checks global binaries, while repo-local runners are present through Bun.

**Files Changed**:

* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Created the implementation evidence ledger and recorded prerequisite 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/skills/apex-spec/scripts/analyze-project.sh --json; fi`
  * Result: PASS - Analyzer returned current session `phase35-session05-persistence-schema-contracts`, `current_session_dir_exists: true`, and Sessions 01-04 complete for Phase 35.
  * Evidence: JSON output showed the active session files are `spec.md` and `tasks.md`.
* Command/check: `if [ -d .spec_system/scripts ]; then bash .spec_system/scripts/check-prereqs.sh --json --env; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/skills/apex-spec/scripts/check-prereqs.sh --json --env; fi`
  * Result: PASS - Environment prerequisites passed.
  * Evidence: JSON output reported `.spec_system`, `jq-1.7`, and `git version 2.43.0` available.

  * Result: PASS - Repo-local tool runners are available.
  * Evidence: Vitest 4.1.6, TypeScript 6.0.3, and Playwright 1.60.0 resolved through Bun.
* Command/check: `sed -n '1,260p' .spec_system/PRD/phase_35/session_05_persistence_schema_contracts.md`
  * Result: PASS - Phase stub source locations and caveats inspected.
  * Evidence: Stub lists AR-D5-001, AR-D5-002, AR-D8-002 storage portion, and source locations for `persistence.ts`, `save-schema.ts`, runtime types, and `runtime-canvas.tsx`.
* UI product-surface check: N/A - No user-facing UI changed for this setup task.
* UI craft check: N/A - No user-facing UI changed for this setup task.

### Task T002 - Create the Session 05 implementation evidence ledger scaffold

**Started**: 2026-06-26 20:19 **Completed**: 2026-06-26 20:20 **Duration**: 1 minute

**Notes**:

* Created the required Session 05 implementation notes ledger.
* Added session metadata, progress summary, environment verification, and the task log structure required for per-task evidence.
* Recorded the repo-local tool-runner caveat so later verification uses `bun run` and `bunx` consistently.

**Files Changed**:

* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Added the scaffold, session start evidence, and T001/T002 task logs.
* `.spec_system/specs/phase35-session05-persistence-schema-contracts/tasks.md` - Added the progress summary and marked T001 complete after evidence was recorded.

**Verification**:

* Command/check: `test -f .spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md`
  * Result: PASS - Implementation notes ledger exists.
  * Evidence: File contains the Session Progress table and task log entries.

### Task T003 - Record baseline references for persistence, schema, claim, runtime load, and browser specs

**Started**: 2026-06-26 20:20 **Completed**: 2026-06-26 20:21 **Duration**: 1 minute

**Notes**:

* Inspected `save-schema.ts` and confirmed the durable/live naming issue: `aiRogueRuntimeSnapshotSchema` is a direct alias of `aiRogueDurableRuntimeSnapshotSchema`, and `AiRogueRuntimeSnapshot` aliases the durable type.
* Inspected `persistence.ts` and confirmed direct claims enter through `normalizeAiRogueClaimEntry` before `transactClaim`, reset already snapshots scoped localStorage keys for compensation, and IndexedDB open maps `onblocked` to a generic blocked error string.
* Inspected `claim-store.ts` and confirmed durable writes update the legacy guard first, then rollback the guard if durable persistence fails.
* Inspected `runtime-canvas.tsx` and confirmed load uses `hydrateAiRogueRuntimeSavePayloadFromDurableSnapshot`, while the prop type still names the payload as `AiRogueDurableRuntimeSnapshot`.
* Inspected existing focused unit and browser specs. Current coverage already includes oversized direct claim rejection, duplicate claim idempotency, durable claim rollback, basic read failures, reset scope, and saved-run empty/malformed UI states.
* Recorded file-size pressure for later split recommendations: `save-schema.ts` has 1367 lines and `persistence.ts` has 1007 lines before this session's edits.

**Files Changed**:

* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Added baseline references and source observations.
* `.spec_system/specs/phase35-session05-persistence-schema-contracts/tasks.md` - Marked prior setup task progress before this baseline task.

**Verification**:

* Command/check: `wc -l src/extensions/ai-rogue/save-schema.ts src/extensions/ai-rogue/persistence.ts src/extensions/ai-rogue/claim-store.ts src/extensions/ai-rogue/views/runtime-canvas.tsx src/extensions/ai-rogue/__tests__/save-schema.test.ts src/extensions/ai-rogue/__tests__/persistence.test.ts src/extensions/ai-rogue/__tests__/claim-store.test.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts`
  * Result: PASS - Target file sizes captured.
  * Evidence: `save-schema.ts` 1367 lines, `persistence.ts` 1007 lines, and total inspected target/test files 6629 lines.
* Command/check: `rg -n "aiRogueRuntimeSnapshotSchema|DurableRuntimeSnapshot|hydrate|saved-run|savedRun|claim|quota|blocked|reset|legacy" src/extensions/ai-rogue/save-schema.ts src/extensions/ai-rogue/persistence.ts src/extensions/ai-rogue/claim-store.ts src/extensions/ai-rogue/views/runtime-canvas.tsx src/extensions/ai-rogue/__tests__/save-schema.test.ts src/extensions/ai-rogue/__tests__/persistence.test.ts src/extensions/ai-rogue/__tests__/claim-store.test.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts`
  * Result: PASS - Baseline references located.
  * Evidence: Search output included `save-schema.ts:685` alias export, `persistence.ts:997` claim normalization, `persistence.ts:926` reset helper, `claim-store.ts` durable rollback paths, runtime load helper usage, and existing focused tests.
* Command/check: `sed -n '667,1048p' src/extensions/ai-rogue/save-schema.ts`
  * Result: PASS - Durable schema and hydration helper inspected.
  * Evidence: Durable schema, alias export, save slot schema, durable type alias, and hydration helper were read.
* Command/check: `sed -n '418,1007p' src/extensions/ai-rogue/persistence.ts`
  * Result: PASS - Claim transaction and reset compensation inspected.
  * Evidence: `transactClaim`, `recordAiRogueClaim`, `resetAiRoguePersistence`, and `createClaimEntry` were read.
* UI product-surface check: N/A - No user-facing UI changed for this baseline task.
* UI craft check: N/A - No user-facing UI changed for this baseline task.

### Task T004 - Replace confusing durable/live runtime snapshot schema aliasing with explicit durable saved-run names

**Started**: 2026-06-26 20:20 **Completed**: 2026-06-26 20:22 **Duration**: 2 minutes

**Notes**:

* Renamed the durable persisted run schema owner to `aiRogueDurableSavedRunSnapshotSchema`.
* Kept `aiRogueDurableRuntimeSnapshotSchema` as a documented compatibility export for existing durable records and consumers.
* Removed the misleading `aiRogueRuntimeSnapshotSchema` export and removed the `AiRogueRuntimeSnapshot` durable alias from `save-schema.ts`, leaving live runtime snapshots owned by `runtime/types.ts`.
* Updated the existing save-schema unit test to assert durable compatibility naming instead of live/durable alias equality.

**Files Changed**:

* `src/extensions/ai-rogue/save-schema.ts` - Added explicit durable saved-run schema/type names, pointed save slots at the saved-run schema, and removed the live-style alias export.
* `src/extensions/ai-rogue/__tests__/save-schema.test.ts` - Updated the naming contract assertion to use the explicit durable saved-run schema.

**Verification**:

* Command/check: `rg -n "aiRogueRuntimeSnapshotSchema|type AiRogueRuntimeSnapshot =|AiRogueRuntimeSnapshot" src/extensions/ai-rogue/save-schema.ts src/extensions/ai-rogue/__tests__/save-schema.test.ts`
  * Result: PASS - No misleading durable/live runtime alias remains in `save-schema.ts` or its schema test.
  * Evidence: `rg` exited with no matches.
* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/save-schema.test.ts`
  * Result: PASS - Focused save-schema tests passed.
  * Evidence: Vitest reported 1 test file passed and 13 tests passed.
* UI product-surface check: N/A - No user-facing UI changed for this schema naming task.
* UI craft check: N/A - No user-facing UI changed for this schema naming task.

**BQC Fixes**:

* Contract alignment: Durable saved-run exports are distinct from live runtime snapshot types (`src/extensions/ai-rogue/save-schema.ts`).

***

### Task T005 - Update durable saved-run hydration helpers and exports with explicit malformed, empty, and ready-state error mapping

**Started**: 2026-06-26 20:22 **Completed**: 2026-06-26 20:24 **Duration**: 2 minutes

**Notes**:

* Added `hydrateAiRogueRuntimeSavePayloadFromDurableSavedRunSnapshot`, which returns a typed result instead of throwing.
* Mapped durable saved-run hydration outcomes to `ready`, `empty`, and `malformed`, with codes `empty` and `malformed`.
* Kept `hydrateAiRogueRuntimeSavePayloadFromDurableSnapshot` as a compatibility wrapper that throws the same stable product-facing messages for existing consumers.
* Moved payload assembly into a named internal helper so durable parsing and runtime hydration remain schema-owned.

**Files Changed**:

* `src/extensions/ai-rogue/save-schema.ts` - Added durable saved-run hydration result types, explicit result helper, and compatibility wrapper.
* `src/extensions/ai-rogue/__tests__/save-schema.test.ts` - Added assertions for ready, empty, and malformed hydration result mapping.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/save-schema.test.ts`
  * Result: PASS - Focused save-schema tests passed.
  * Evidence: Vitest reported 1 test file passed and 13 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the durable saved-run exports and compatibility wrapper.
  * Evidence: `tsc --noEmit` exited successfully.
* UI product-surface check: N/A - No user-facing UI changed for this schema helper task.
* UI craft check: N/A - No user-facing UI changed for this schema helper task.

**BQC Fixes**:

* Contract alignment: Durable saved-run hydration now exposes explicit result states and stable error codes (`src/extensions/ai-rogue/save-schema.ts`).
* Failure path completeness: Existing throwing behavior is backed by a non-throwing result helper for callers that need controlled error handling (`src/extensions/ai-rogue/save-schema.ts`).

***

### Task T006 - Update runtime load consumers to use durable saved-run types and helper names with product-facing load/reset states

**Started**: 2026-06-26 20:24 **Completed**: 2026-06-26 20:26 **Duration**: 2 minutes

**Notes**:

* Updated the runtime canvas load prop to consume `AiRogueDurableSavedRunSnapshot`.
* Updated runtime load handling to call the non-throwing durable saved-run hydration helper and then raise the same stable player-facing message for empty or malformed loads.
* Updated the save-state hook return type so Play route load consumers use durable saved-run names consistently.
* Renamed runtime-canvas test helper types from durable runtime wording to durable saved-run wording.
* Preserved visible load/reset copy. Failed durable loads still surface player-facing messages such as "AI Rogue save slot is empty." through the runtime error state.

**Files Changed**:

* `src/extensions/ai-rogue/views/runtime-canvas.tsx` - Switched runtime load props and helper use to durable saved-run naming and result mapping.
* `src/extensions/ai-rogue/use-save-state.ts` - Updated load snapshot result typing to `AiRogueDurableSavedRunSnapshot`.
* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Updated durable saved-run test types and helper names.

**Verification**:

* Command/check: `rg -n "DurableRuntimeSnapshot|hydrateAiRogueRuntimeSavePayloadFromDurableSnapshot|createDurableRuntimeSnapshot|createEmptyDurableRuntimeSnapshot" src/extensions/ai-rogue/views/runtime-canvas.tsx src/extensions/ai-rogue/use-save-state.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Runtime load consumer path no longer uses durable-runtime names or the throwing helper directly.
  * Evidence: `rg` exited with no matches.
* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Runtime canvas component tests passed.
  * Evidence: Vitest reported 1 test file passed and 13 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the durable saved-run consumer types.
  * Evidence: `tsc --noEmit` exited successfully.
* UI product-surface check: PASS - `runtime-canvas.test.tsx` renders the component and confirms failed durable saved-run loads show product-facing runtime error text, not implementation diagnostics.
* UI craft check: PASS - No layout or visual hierarchy changed; existing rendered component states for ready, empty, and malformed saved-run loads stayed covered by component tests.

**BQC Fixes**:

* Contract alignment: Runtime load consumers now use durable saved-run names instead of durable/live runtime aliases (`src/extensions/ai-rogue/views/runtime-canvas.tsx`, `src/extensions/ai-rogue/use-save-state.ts`).
* Failure path completeness: Empty and malformed durable saved-run loads use explicit helper results before surfacing stable player-facing messages (`src/extensions/ai-rogue/views/runtime-canvas.tsx`).

### Task T007 - Audit claim write entry points so direct writes still normalize before wallet and ledger mutation with duplicate-trigger prevention while in-flight

**Started**: 2026-06-26 20:26 **Completed**: 2026-06-26 20:29 **Duration**: 3 minutes

**Notes**:

* Audited claim write callers and confirmed UI duplicate prevention already exists in `ledger-view.tsx` through `claimInFlightRef` and in `use-save-state.ts` through `runExclusive`.
* Added persistence-level duplicate prevention keyed by claim redemption key so direct `recordAiRogueClaim` calls cannot double-submit the same claim while the first transaction is in flight.
* Added adapter-side claim normalization in `createAiRogueIndexedDbAdapter().transactClaim` so even direct adapter use parses through the durable claim schema before wallet and ledger mutation.
* Added a focused persistence test that holds the first same-key transaction open, rejects the duplicate write, then verifies only one wallet/ledger mutation commits.

**Files Changed**:

* `src/extensions/ai-rogue/persistence.ts` - Added in-flight redemption-key guard and adapter-side normalization before claim transaction writes.
* `src/extensions/ai-rogue/__tests__/persistence.test.ts` - Added delayed transaction coverage for duplicate in-flight claim writes.

**Verification**:

* Command/check: `rg -n "recordClaim|recordAiRogueClaim|writeAiRogueClaimEntryDurable|Claim recorded|Claimed|Claim" src/extensions/ai-rogue -g '*.ts' -g '*.tsx'`
  * Result: PASS - Claim write entry points were traced.
  * Evidence: Output showed `recordAiRogueClaim`, durable claim bridge, `use-save-state.ts` `runExclusive`, and `ledger-view.tsx` `claimInFlightRef` paths.
* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/persistence.test.ts`
  * Result: PASS - Focused persistence tests passed.
  * Evidence: Vitest reported 1 test file passed and 17 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the in-flight guard and test changes.
  * Evidence: `tsc --noEmit` exited successfully after the test resolver narrowing fix.
* UI product-surface check: N/A - No user-facing UI changed for this persistence-boundary task.
* UI craft check: N/A - No user-facing UI changed for this persistence-boundary task.

**BQC Fixes**:

* Duplicate action prevention: Same-key claim writes now fail fast while a direct persistence write is already in flight (`src/extensions/ai-rogue/persistence.ts`).
* Trust boundary enforcement: The IndexedDB transaction adapter normalizes claims before wallet and ledger mutation (`src/extensions/ai-rogue/persistence.ts`).
* Concurrency safety: Direct same-key claim write races are guarded before transactional mutation begins (`src/extensions/ai-rogue/persistence.ts`).

***

### Task T008 - Preserve legacy claim guard rollback around durable write failures with compensation on failure

**Started**: 2026-06-26 20:29 **Completed**: 2026-06-26 20:30 **Duration**: 1 minute

**Notes**:

* Verified the existing durable claim bridge snapshots the previous legacy guard raw value before appending a new claim.
* Added coverage for the non-empty compensation path: when a new durable write fails after an existing legacy record, the original legacy record is restored exactly.
* No production code change was required for this task because the existing `restoreClaimRecord` path already satisfied the compensation requirement.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/claim-store.test.ts` - Added rollback coverage for restoring a previous legacy claim guard after durable write failure.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/claim-store.test.ts`
  * Result: PASS - Focused claim-store tests passed.
  * Evidence: Vitest reported 1 test file passed and 10 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the expanded claim-store coverage.
  * Evidence: `tsc --noEmit` exited successfully.
* UI product-surface check: N/A - No user-facing UI changed for this claim-store compensation task.
* UI craft check: N/A - No user-facing UI changed for this claim-store compensation task.

**BQC Fixes**:

* Failure path completeness: Durable claim write failure now has explicit non-empty legacy rollback coverage (`src/extensions/ai-rogue/__tests__/claim-store.test.ts`).
* Contract alignment: Legacy guard and durable wallet/ledger records remain aligned when durable persistence fails (`src/extensions/ai-rogue/__tests__/claim-store.test.ts`).

***

### Task T009 - Harden IndexedDB open, blocked, quota-like, read, write, and transaction failure mapping without adding hosted storage

**Started**: 2026-06-26 20:30 **Completed**: 2026-06-26 20:32 **Duration**: 2 minutes

**Notes**:

* Added centralized IndexedDB error classification for blocked/open-like and quota-like failures.
* Added stable result codes `storage_blocked` and `quota_exceeded` while preserving existing read, write, and transaction failure categories for ordinary failures.
* Updated save-state status mapping so blocked storage is treated as a denied browser-state problem; quota-like failures remain controlled errors.
* Added focused persistence tests for blocked reads, quota-like save-slot writes, and quota-like claim transactions.
* Confirmed no hosted persistence, remote calls, analytics, collectors, or bridge requests were added.

**Files Changed**:

* `src/extensions/ai-rogue/persistence.ts` - Added IndexedDB error classification and applied it to read/write/claim/upgrade failure paths.
* `src/extensions/ai-rogue/use-save-state.ts` - Mapped `storage_blocked` to denied save-state status.
* `src/extensions/ai-rogue/__tests__/persistence.test.ts` - Added blocked and quota-like storage failure coverage.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/persistence.test.ts`
  * Result: PASS - Focused persistence tests passed.
  * Evidence: Vitest reported 1 test file passed and 20 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the new persistence result codes and status mapping.
  * Evidence: `tsc --noEmit` exited successfully.
* UI product-surface check: N/A - No rendered product layout changed for this storage error mapping task.
* UI craft check: N/A - No rendered product layout changed for this storage error mapping task.

**BQC Fixes**:

* Failure path completeness: Blocked/open-like and quota-like IndexedDB failures now return stable result codes and product-safe messages (`src/extensions/ai-rogue/persistence.ts`).
* Error information boundaries: User-facing persistence messages avoid raw exception text while preserving detail in warnings for tests and diagnostics (`src/extensions/ai-rogue/persistence.ts`).
* External dependency resilience: Browser storage failure categories are explicit without adding hosted fallback storage (`src/extensions/ai-rogue/persistence.ts`).

### Task T010 - Harden reset compensation so AI Rogue localStorage is restored when IndexedDB reset fails and unrelated keys are untouched

**Started**: 2026-06-26 20:32 **Completed**: 2026-06-26 20:34 **Duration**: 2 minutes

**Notes**:

* Preserved the existing reset snapshot-and-restore strategy for scoped AI Rogue localStorage keys.
* Updated the IndexedDB reset failure path to use the shared storage failure mapper while preserving localStorage compensation warnings.
* Added focused coverage proving preferences and legacy claim localStorage keys are restored when IndexedDB reset fails, unrelated localStorage keys remain untouched, and durable wallet/ledger records remain intact after the failed reset.

**Files Changed**:

* `src/extensions/ai-rogue/persistence.ts` - Allowed IndexedDB failure mapping to preserve prior warnings and applied it to reset failure handling.
* `src/extensions/ai-rogue/__tests__/persistence.test.ts` - Added reset-failure compensation coverage.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/persistence.test.ts`
  * Result: PASS - Focused persistence tests passed.
  * Evidence: Vitest reported 1 test file passed and 21 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted reset failure mapping and tests.
  * Evidence: `tsc --noEmit` exited successfully.
* UI product-surface check: N/A - No user-facing UI changed for this reset persistence task.
* UI craft check: N/A - No user-facing UI changed for this reset persistence task.

**BQC Fixes**:

* Failure path completeness: Reset failure now preserves compensation warnings through the shared IndexedDB failure mapper (`src/extensions/ai-rogue/persistence.ts`).
* Contract alignment: Scoped AI Rogue localStorage keys are restored when IndexedDB reset fails, and unrelated keys remain untouched (`src/extensions/ai-rogue/__tests__/persistence.test.ts`).

**Started**: 2026-06-26 20:35 **Completed**: 2026-06-26 20:36 **Duration**: 1 minute

**Notes**:

* Preserved existing claim parity coverage for normal claims, duplicate claims, and oversized direct claim rejection before wallet/ledger divergence.
* Added duplicate in-flight claim write coverage for direct `recordAiRogueClaim` calls.
* Preserved existing transaction rollback coverage and added quota-like transaction failure coverage.

**Started**: 2026-06-26 20:37 **Completed**: 2026-06-26 20:39 **Duration**: 2 minutes

**Notes**:

* Preserved existing ready durable saved-run load coverage.

* Added malformed durable saved-run coverage for schema-owned hydration failures.
* Added failed load-callback coverage and changed that branch to surface a visible product-facing runtime error instead of only updating hidden event state.

**Files Changed**:

* `src/extensions/ai-rogue/views/runtime-canvas.tsx` - Surfaced failed load callbacks through the runtime error state with the stable player-facing message.
* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Added malformed durable saved-run and failed load-callback product-state tests.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Focused runtime canvas tests passed.
  * Evidence: Vitest reported 1 test file passed and 15 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted runtime canvas and test changes.
  * Evidence: `tsc --noEmit` exited successfully.
* UI product-surface check: PASS - Testing Library rendered the component and confirmed malformed and failed saved-run loads show product-facing "Runtime error" states with stable messages, not implementation diagnostics.
* UI craft check: PASS - No layout structure changed; existing controls and error overlay pattern were reused.

**BQC Fixes**:

* Failure path completeness: Failed saved-run load callbacks now have visible product-facing runtime error handling (`src/extensions/ai-rogue/views/runtime-canvas.tsx`).
* Product surface discipline: Tests assert player-facing error copy for malformed and failed saved-run loads (`src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`).

### Task T015 - Extend browser persistence and ledger flows for save/load readiness, reset scope, wallet/ledger parity, and private-field absence

**Started**: 2026-06-26 20:39 **Completed**: 2026-06-26 20:41 **Duration**: 2 minutes

**Notes**:

* Extended the AI Rogue persistence browser spec to assert wallet/ledger claim amount and balance parity after claim and refresh.
* Extended the Play route check to assert Save is enabled and Load is disabled while the primary slot is empty.
* Extended durable privacy checks to scan the IndexedDB-derived state after loadout purchase.
* Extended the AI Rogue ledger browser spec to assert wallet/ledger parity after claim and refresh.

**Files Changed**:

* `tests/e2e/ai-rogue-persistence.spec.ts` - Added save/load readiness, wallet/ledger parity, and durable privacy assertions.
* `tests/e2e/ai-rogue-ledger.spec.ts` - Added wallet/ledger parity assertions after claim and refresh.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript accepted the updated Playwright helper shapes.
  * Evidence: `tsc --noEmit` exited successfully.
* Command/check: `bunx playwright test tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts`
  * Result: PASS - Focused AI Rogue browser specs passed.
  * Evidence: Playwright reported 2 passed tests. The web server emitted transient startup `curl` connection retries before the tests ran, then both specs passed.
* UI product-surface check: PASS - Browser specs loaded `/extensions/ai-rogue/play`, `/extensions/ai-rogue/ledger`, `/extensions/ai-rogue/loadout`, and `/extensions/ai-rogue/settings` and asserted product-facing controls/copy.
* UI craft check: PASS - No layout or visual styling changed; browser checks confirmed controls remained discoverable and enabled/disabled states matched save-slot readiness.

**BQC Fixes**:

* Contract alignment: Browser tests now assert wallet balance and ledger amount/balanceAfter parity through IndexedDB (`tests/e2e/ai-rogue-persistence.spec.ts`, `tests/e2e/ai-rogue-ledger.spec.ts`).
* Product surface discipline: Browser tests continue to assert private strings are absent from visible body text and durable state snapshots (`tests/e2e/ai-rogue-persistence.spec.ts`).

### Task T016 - Run focused AI Rogue unit tests for schema, persistence, claim store, and runtime canvas

**Started**: 2026-06-26 20:41 **Completed**: 2026-06-26 20:42 **Duration**: 1 minute

**Notes**:

* Ran the exact focused unit-test command required by the session checklist.
* Verified schema, persistence, claim-store, and runtime-canvas coverage together after all implementation/test edits.

**Files Changed**:

* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Recorded aggregate unit-test evidence.

**Verification**:

* Command/check: `bun run test -- src/extensions/ai-rogue/__tests__/save-schema.test.ts src/extensions/ai-rogue/__tests__/persistence.test.ts src/extensions/ai-rogue/__tests__/claim-store.test.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx`
  * Result: PASS - Focused AI Rogue unit tests passed.
  * Evidence: Vitest reported 4 test files passed and 59 tests passed.
* UI product-surface check: PASS - Runtime canvas component tests in the aggregate command rendered product-facing saved-run states.
* UI craft check: PASS - No layout changes were introduced by the test gate; component tests reused existing controls and overlay patterns.

### Task T017 - Run focused AI Rogue browser persistence and ledger specs

**Started**: 2026-06-26 20:42 **Completed**: 2026-06-26 20:44 **Duration**: 2 minutes

**Notes**:

* Ran the required focused Playwright persistence and ledger specs.
* First T017 run found a flaky selector in `ai-rogue-persistence.spec.ts`: `getByText("Run tools").click()` did not reliably open the details summary before asserting the save/load panel.
* Fixed the spec to target `details` > `summary` directly, assert the `open` attribute, then assert the Save and load panel content inside that details element.
* Reran the focused browser specs successfully.

**Files Changed**:

* `tests/e2e/ai-rogue-persistence.spec.ts` - Hardened the Run tools details selector and open-state assertion.
* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Recorded browser gate evidence.

**Verification**:

* Command/check: `bunx playwright test tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts`
  * Result: FAIL then PASS after selector repair.
  * Evidence: Initial run passed ledger but failed persistence waiting for "Save and load"; rerun reported 2 passed tests.
* UI product-surface check: PASS - Browser specs loaded AI Rogue Ledger, Play, Loadout, and Settings surfaces and asserted product-facing controls/copy.
* UI craft check: PASS - No styling/layout change; test selector now follows the actual details/summary interaction.

**BQC Fixes**:

* State freshness on re-entry: Browser test now asserts the Run tools details element is open before checking nested save/load state (`tests/e2e/ai-rogue-persistence.spec.ts`).

### Task T018 - Run static quality gates for TypeScript, lint, and formatting

**Started**: 2026-06-26 20:44 **Completed**: 2026-06-26 20:49 **Duration**: 5 minutes

**Notes**:

* Ran the exact static gate command required by the session checklist.
* First run reached lint and failed on Prettier formatting in touched source/test files.
* Ran targeted Prettier on touched files and reran the gate.
* Second run reached `format:check` and found generated session `spec.md` formatting.
* Formatted the generated session spec and reran the exact gate successfully.

**Files Changed**:

* `src/extensions/ai-rogue/save-schema.ts` - Prettier formatting.
* `src/extensions/ai-rogue/persistence.ts` - Prettier formatting.
* `src/extensions/ai-rogue/views/runtime-canvas.tsx` - Prettier formatting.
* `src/extensions/ai-rogue/__tests__/save-schema.test.ts` - Prettier formatting.
* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - Prettier formatting.
* `tests/e2e/ai-rogue-ledger.spec.ts` - Prettier formatting.
* `.spec_system/specs/phase35-session05-persistence-schema-contracts/spec.md` - Prettier formatting for generated session artifact.
* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - T018 evidence.

**Verification**:

* Command/check: `bun run typecheck && bun run lint && bun run format:check`
  * Result: FAIL then PASS after targeted formatting.
  * Evidence: Final run completed `tsc --noEmit`, `eslint .`, and `prettier --check .`; final output reported all matched files use Prettier code style.
* UI product-surface check: N/A - Static gate only; no rendered product surface changed during formatting.
* UI craft check: N/A - Static gate only; no rendered product surface changed during formatting.

### Task T019 - Scan AI Rogue changes for hosted writes, remote calls, private fields, and public-demo bridge regressions

**Started**: 2026-06-26 20:49 **Completed**: 2026-06-26 20:51 **Duration**: 2 minutes

**Notes**:

* Scanned the AI Rogue source/test diff for remote calls, hosted persistence, bridge paths, analytics, collectors, credentials, and private-field strings.
* Diff scan found no added `fetch`, `XMLHttpRequest`, `sendBeacon`, analytics, collectors, public-demo bridge calls, hosted writes, or remote sync.
* Diff scan found one added test name saying "without adding hosted storage" and added negative privacy assertions for `/home/operator/private` and `secret prompt body`.
* Full-source scan found pre-existing local asset `fetch(url)` in runtime audio and pre-existing private-string test fixtures/assertions. No new remote persistence path was added.

**Files Changed**:

* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Recorded privacy/source scan evidence.

**Verification**:

* Command/check: `git diff -- src/extensions/ai-rogue tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts | rg -n "^\\+.*(fetch\\(|XMLHttpRequest|sendBeacon|https?://|analytics|collector|bridge|rawPrompt|secret prompt body|/home/operator/private|api key|credential|token|provider payload|Pages Functions|hosted|remote sync)"`
  * Result: PASS - No added remote calls or bridge paths.
  * Evidence: Only added hits were a test name containing "hosted storage" and negative privacy assertions checking private strings are absent.
* Command/check: `rg -n "fetch\\(|XMLHttpRequest|sendBeacon|analytics|collector|remote sync|hosted persistence|Pages Functions|public-demo bridge|provider payload|raw payload|secret prompt body|/home/operator/private" src/extensions/ai-rogue tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts`
  * Result: PASS - Source hits were pre-existing asset fetch/private-pattern and negative privacy test fixtures; no hosted persistence regression found.
  * Evidence: Output included `runtime/audio.ts` local asset fetch and multiple tests asserting private strings do not render or persist.
* Command/check: `git diff --stat -- src/extensions/ai-rogue tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts`
  * Result: PASS - AI Rogue source/test change scope inspected.
  * Evidence: Diff stat covered 10 AI Rogue source/test files with focused persistence/schema/test changes.
* UI product-surface check: PASS - Scan confirmed added browser assertions continue to check product surfaces for absence of private strings.
* UI craft check: N/A - Source/privacy scan did not change UI layout or styling.

### Task T020 - Validate ASCII/LF requirements and complete split recommendations for oversized persistence files

**Started**: 2026-06-26 20:51 **Completed**: 2026-06-26 20:53 **Duration**: 2 minutes

**Notes**:

* Added split recommendations for the oversized `save-schema.ts` and `persistence.ts` files.
* Confirmed `save-schema.ts` is 1419 lines and `persistence.ts` is 1088 lines after this session, so later Phase 35 refactor sessions should split them.
* Verified changed source, test, and session files are ASCII-only and have LF line endings.
* Verified diff whitespace checks pass.
* Verified session artifacts remain Prettier-formatted after the final notes/checklist updates.

**Files Changed**:

* `.spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md` - Added split recommendations and T020 evidence.

**Verification**:

* Command/check: `wc -l src/extensions/ai-rogue/save-schema.ts src/extensions/ai-rogue/persistence.ts`
  * Result: PASS - Oversized file sizes captured for split recommendations.
  * Evidence: `save-schema.ts` 1419 lines; `persistence.ts` 1088 lines.
* Command/check: `bash -lc 'files=$(git diff --name-only -- src/extensions/ai-rogue tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts .spec_system/specs/phase35-session05-persistence-schema-contracts); if [ -n "$files" ]; then perl -ne '\''if (/[^\\x00-\\x7F]/) { print "$ARGV:$.:$_"; $bad=1 } END { exit($bad // 0) }'\'' $files; fi'`
  * Result: PASS - No non-ASCII characters found.
  * Evidence: Command exited successfully with no output.

  * Result: PASS - No CRLF line endings found.
  * Evidence: Command exited successfully with no output.
* Command/check: `git diff --check -- src/extensions/ai-rogue tests/e2e/ai-rogue-persistence.spec.ts tests/e2e/ai-rogue-ledger.spec.ts .spec_system/specs/phase35-session05-persistence-schema-contracts`
  * Result: PASS - No diff whitespace errors.
  * Evidence: Command exited successfully with no output.
* Command/check: `bunx prettier --check .spec_system/specs/phase35-session05-persistence-schema-contracts/spec.md .spec_system/specs/phase35-session05-persistence-schema-contracts/tasks.md .spec_system/specs/phase35-session05-persistence-schema-contracts/implementation-notes.md`
  * Result: PASS - Session artifacts are formatted.
  * Evidence: Prettier reported all matched files use Prettier code style.
* UI product-surface check: N/A - Encoding, line-ending, and split-note task only.
* UI craft check: N/A - Encoding, line-ending, and split-note task only.

## Split Recommendations

### `src/extensions/ai-rogue/save-schema.ts`

* Keep current behavior stable until Phase 35 module-split sessions; this file is still oversized and owns multiple durable boundaries.
* Recommended first split: move durable saved-run schemas, hydration result types, and hydration helpers into `save-schema/saved-run.ts` or a similarly local module.
* Recommended second split: move wallet, ledger, and upgrade purchase helpers into `save-schema/wallet-ledger.ts` so claim/economy persistence can depend on a smaller contract surface.
* Recommended third split: move progression/loadout/objective schemas into a progression-focused schema module once Phase 35 world/type cleanup is ready.
* Preserve the compatibility export `aiRogueDurableRuntimeSnapshotSchema` until all durable consumers have moved to durable saved-run naming.

### `src/extensions/ai-rogue/persistence.ts`

* Keep this session's behavior in one file until Session 06/07 refactors can move callers safely; this file remains oversized and mixes adapter, localStorage, result mapping, and reset ownership.
* Recommended first split: move the IndexedDB adapter, store constants, request/transaction helpers, and open/blocked/quota error mapping into `persistence/indexed-db.ts`.
* Recommended second split: move localStorage preference and legacy claim migration helpers into `persistence/local-storage.ts`.
* Recommended third split: move reset compensation and shared result/error helpers into `persistence/results.ts` or `persistence/reset.ts`.
* Preserve `recordAiRogueClaim` as the public durable claim write boundary unless a later session replaces it with an explicit persistence service object.
