### Task T001 - Verify upstream Dream engine, dashboard, setup, and Vite hunks

**Started**: 2026-06-30 00:25 **Completed**: 2026-06-30 00:26 **Duration**: 1 minute

**Notes**:

* Audited upstream Dream engine behavior in `/home/aiwithapex/projects/claudeos/claude-os-v2.8.1/scripts/run-dream.ts`.
* Recorded upstream engine ids and order: `hermes`, `claude`, `openrouter`, `codex`.
* Verified upstream cron runner reads `~/.claude-os/config.json`, auto-selects the first available engine only when the stored choice is missing or invalid, and supports Codex/OpenRouter prompt assembly as a superseded reference.
* Audited upstream setup and dashboard controls. Both read `/__dream_engines`; setup saves `/__set_dream_engine`; dashboard generation uses upstream-only `/__trigger_dream`.
* Confirmed AI OS must port engine readiness and persistence only, while retaining AI OS Dream execution through `/__run_dream` and AI OS private config.

**Files Changed**:

* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded upstream supersession audit evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T001 complete and updated progress.

**Verification**:

* Command/check: `wc -l /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/scripts/run-dream.ts /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/src/routes/index.tsx /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/src/routes/setup.tsx /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/vite.config.ts`
  * Result: PASS - upstream files are present and readable.
  * Evidence: line counts returned for all four upstream files.
* Command/check: `rg -n "engine|Engine|dream|Dream|__run_dream|__dream|setup|cadence|Anthropic|Claude|OpenAI|Gemini|Codex" /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/scripts/run-dream.ts /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/src/routes/index.tsx /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/src/routes/setup.tsx /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/vite.config.ts`
  * Result: PASS - upstream Dream engine picker, endpoint, and trigger references were located.
  * Evidence: matched `/__set_dream_engine`, `/__dream_engines`, `/__trigger_dream`, engine readiness rows, setup engine step, and runner engine resolution.
* Command/check: `sed -n '1,260p' /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/scripts/run-dream.ts` plus targeted `sed` reads for upstream dashboard, setup, and Vite Dream sections
  * Result: PASS - relevant upstream implementation sections inspected.
  * Evidence: inspected runner config/auto-selection, dashboard picker/generate UI, setup `StepDreamEngine`, and Vite engine endpoints.
* UI product-surface check: N/A - audit-only task.
* UI craft check: N/A - audit-only task.

**BQC Fixes**:

* N/A - no runtime code changed.

### Task T004 - Add Dream engine contract types, readiness states, safe labels, and export wiring

**Started**: 2026-06-30 00:28 **Completed**: 2026-06-30 00:30 **Duration**: 2 minutes

**Notes**:

* Added canonical Dream engine ids and legacy engine ids in `scripts/lib/dream/contracts.ts`.
* Added readiness status/code unions, runtime-provider mapping type, selection source type, engine definition type, selected-engine type, and browser-safe projection types.
* Verified `scripts/lib/dream/index.ts` already exports `contracts.ts`, so the new contract surface is wired through the existing Dream barrel export.

**Files Changed**:

* `scripts/lib/dream/contracts.ts` - added Dream engine contract, readiness, selection, and projection types.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T004 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T004 complete and updated progress.

**Verification**:

* Command/check: `rg -n "DREAM_ENGINE_IDS|DreamEngineProjection|DreamEngineListProjection|export \\* from \\\"./contracts\\\"" scripts/lib/dream/contracts.ts scripts/lib/dream/index.ts`
  * Result: PASS - new engine contracts are present and exported through the existing barrel.
  * Evidence: matches found in `contracts.ts`; `index.ts` exports `./contracts`.
* Command/check: `bunx tsc --noEmit -p tsconfig.scripts.json --pretty false`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: no compiler diagnostics were emitted.
* UI product-surface check: N/A - shared script contract task.
* UI craft check: N/A - shared script contract task.

**BQC Fixes**:

* Contract alignment: added shared types before implementation so config, endpoints, runtime, and UI use the same engine ids and readiness states (`scripts/lib/dream/contracts.ts`).

***

### Task T003 - Create implementation evidence file

**Started**: 2026-06-30 00:27 **Completed**: 2026-06-30 00:28 **Duration**: 1 minute

**Notes**:

* Created this implementation evidence file with required session progress and task log tables.
* Added stable evidence sections for upstream supersession audit, selected-engine behavior, endpoint verification, and runtime proof.
* Preserved ASCII-only content and LF line endings in the session artifact.

**Files Changed**:

* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - created and extended evidence tracking sections.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T003 complete and updated progress.

**Verification**:

* Command/check: `find .spec_system/specs/phase38-session07-dream-engine-product-integration -maxdepth 1 -type f -print | sort`
  * Result: PASS - session evidence file exists with `spec.md` and `tasks.md`.
  * Evidence: command listed `implementation-notes.md` after scaffold creation.

* UI craft check: N/A - session artifact task.

**BQC Fixes**:

* N/A - no runtime code changed.

***

## Upstream Supersession Audit

* Upstream `scripts/run-dream.ts` remains superseded. AI OS Dream execution stays in `scripts/lib/dream/execution.ts`, `scripts/scheduler-runner.ts`, and `scripts/dashboard-dream-run.ts`.
* Upstream engine ids and readiness order are recorded for porting: `hermes`, `claude`, `openrouter`, `codex`.
* Upstream `/__trigger_dream` is superseded by AI OS `/__run_dream`. This session must not add a second Dream execution route.
* Upstream writes to `~/.claude-os/config.json`; this session must write selected engines to AI OS private config with legacy read compatibility only.

## Selected-Engine Behavior Evidence

* T005 added `scripts/lib/dream/engine-config.ts` as the AI OS private config owner.
* AI OS reads selected engine from `~/.ai-os/config.json` first, then reads legacy `~/.claude-os/config.json` only for compatibility.
* AI OS writes selected engine only to its private config root and preserves unrelated config fields.
* Supported runtime mapping is explicit: `codex` -> `codex-account`, `openai-api` -> `openai-api`, legacy `openrouter`/`claude`/`hermes` -> unavailable unsupported states.
* Safe browser projection exposes engine ids, labels, readiness states, recovery copy, and costs only; it does not expose config paths, env values, prompts, transcripts, or auth JSON.

## Endpoint Verification Evidence

* T006 added pure endpoint helpers in `scripts/lib/dream/engine-endpoints.ts`.
* Read helper returns safe engine readiness projection with `ok: true`, selected engine id/source, readiness states, and no private paths.
* Write helper requires the provided token to match the refresh token before parsing or writing.
* Write helper maps oversized body, invalid JSON, missing payload, invalid engine id, invalid token, read failure, and write failure to stable safe error bodies.
* T008 wired the helpers into Vite middleware with loopback and Host-header guards.
* `/__dream_engines` is a loopback-gated safe read.
* `/__set_dream_engine` is loopback-gated and token-gated before body parsing.
* Both middleware responses use no-store JSON with `X-Content-Type-Options: nosniff`.

## Runtime Proof Evidence

* T007 wires `executeDream()` to resolve the selected Dream engine before creating the provider runtime.
* `codex` and `openai-api` selections map explicitly to existing AI runtime providers; legacy `openrouter`, `claude`, and `hermes` selections fail with `unsupported-engine` instead of falling back.
* Existing activation gates, aggregate refresh, post-aggregate gates, locks, provider timeout, validation, fallback output, continuity merge, and write paths remain in place.
* `scripts/dashboard-dream-run.ts` prints a safe selected-engine label before running the scheduler job.
* Existing tests for Dream execution and scheduler Dream handler pass after selected-engine wiring.

### Task T002 - Characterize current Dream execution, setup, dashboard, and control-plane ownership

**Started**: 2026-06-30 00:26 **Completed**: 2026-06-30 00:27 **Duration**: 1 minute

**Notes**:

* Verified AI OS Dream execution is centralized in `scripts/lib/dream/execution.ts`, with activation gates, material readiness, locks, runtime state, continuity merge, output validation, fallback output, timeout handling, and write paths already implemented.
* Confirmed runtime selection currently comes from `loadHostAiRuntimeConfig(options.env)` only; no Dream-specific selected-engine config owner exists yet.
* Verified dashboard-triggered runs use `scripts/dashboard-dream-run.ts` through scheduler job `dream`, then refresh live data only when Dream writes output.
* Verified setup modal has seven content steps, with Dream cadence at step 6 and final activation at step 7.
* Verified home dashboard currently renders `DreamHero`, `DreamRunButton`, and `DreamSourcesStrip`, but does not project Dream health into `DreamHero` and has no engine readiness control.
* Verified `vite.config.ts` already provides loopback, Host-header, token, concurrency, and safe async patterns around `/__run_dream`, `/__refresh_data`, and Trend Finder run routes.

**Files Changed**:

* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded current ownership characterization.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T002 complete and updated progress.

**Verification**:

* Command/check: `sed -n '1,320p' scripts/lib/dream/contracts.ts`
  * Result: PASS - existing Dream contracts inspected.
  * Evidence: no engine ids, engine readiness, or browser engine projection types exist yet.
* Command/check: `sed -n '1,980p' scripts/lib/dream/execution.ts`
  * Result: PASS - Dream execution flow inspected end to end.
  * Evidence: selected provider is currently derived from host AI runtime env, with no Dream engine config input.
* Command/check: `sed -n '1,260p' scripts/dashboard-dream-run.ts`
  * Result: PASS - dashboard Dream trigger path inspected.
  * Evidence: it calls scheduler job `dream` and refreshes aggregate only after output exists.
* Command/check: `sed -n '1,320p' src/components/setup/setup-modal.tsx`
  * Result: PASS - setup modal step ownership inspected.
  * Evidence: step 6 renders `StepDream`; step 7 renders `StepYoureSet`.
* Command/check: `sed -n '1,320p' src/components/home/dream-hero.tsx`
  * Result: PASS - current Dream hero behavior inspected.
  * Evidence: it renders `DreamRunButton`, generated review states, public demo copy, and scheduler-command empty copy.
* Command/check: `rg -n "__run_dream|__refresh_data|__token|isLoopback|REFRESH_TOKEN|dream|Dream" vite.config.ts`
  * Result: PASS - local control-plane ownership inspected.
  * Evidence: token-gated `/__run_dream` and loopback guards found.
* UI product-surface check: N/A - characterization-only task.
* UI craft check: N/A - characterization-only task.

**BQC Fixes**:

* N/A - no runtime code changed.

### Task T005 - Implement AI OS Dream engine config read/write and projections

**Started**: 2026-06-30 00:30 **Completed**: 2026-06-30 00:34 **Duration**: 4 minutes

**Notes**:

* Created `scripts/lib/dream/engine-config.ts` with canonical engine definitions, AI OS private config paths, legacy read compatibility, schema-validated selection input, selected-engine read/write helpers, runtime config mapping, readiness probing, and browser-safe projections.
* Writes target `~/.ai-os/config.json` through the resolved AI OS root, preserve existing object fields, set both `dreamEngine` and `dream.engine.selectedEngineId`, and write newline JSON with private permissions.
* Legacy reads use `~/.claude-os/config.json` only when the AI OS config has no valid selected engine.
* Unsupported upstream engines are represented as `unsupported` projections with recovery copy instead of being silently mapped to a supported runtime.
* Added `engine-config` to the Dream barrel export.

**Files Changed**:

* `scripts/lib/dream/contracts.ts` - added readiness codes needed for runtime status mapping.
* `scripts/lib/dream/engine-config.ts` - added AI OS Dream engine config owner and safe projection helpers.
* `scripts/lib/dream/index.ts` - exported the engine config module.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T005 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T005 complete and updated progress.

**Verification**:

* Command/check: `bunx tsc --noEmit -p tsconfig.scripts.json --pretty false`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: no compiler diagnostics were emitted after adding `engine-config.ts` and the barrel export.
* Command/check: `bun --eval 'import { mkdtempSync, readFileSync, rmSync } from "node:fs"; ...'`
  * Result: PASS - temp-root smoke check parsed `{ engine: "codex" }`, wrote AI OS config, read `codex` from AI OS config, and projected a ready selected Codex engine.
  * Evidence: command returned `{"parsed":true,"selection":{"engineId":"codex","source":"ai-os-config","persisted":true},"selected":"codex","hasReadyEngine":true,"persisted":"codex"}`.
* Command/check: `rg -n "readDreamEngineListProjection|writeDreamEngineSelection|parseDreamEngineSelectionInput|createDreamEngineRuntimeConfig|engine-config" scripts/lib/dream/engine-config.ts scripts/lib/dream/index.ts scripts/lib/dream/contracts.ts`
  * Result: PASS - config owner API and export wiring are present.
  * Evidence: matches found for parse, read, write, runtime config mapping, and `export * from "./engine-config"`.
* UI product-surface check: N/A - script config owner task.
* UI craft check: N/A - script config owner task.

**BQC Fixes**:

* Trust boundary enforcement: added schema-validated write input parsing and explicit invalid-selection errors (`scripts/lib/dream/engine-config.ts`).
* Error information boundaries: browser projections return safe labels/recovery copy without private paths or secret-shaped values (`scripts/lib/dream/engine-config.ts`).
* Contract alignment: added runtime-status readiness codes consumed by the config projection (`scripts/lib/dream/contracts.ts`).

### Task T006 - Add pure Dream engine endpoint helpers

**Started**: 2026-06-30 00:34 **Completed**: 2026-06-30 00:37 **Duration**: 3 minutes

**Notes**:

* Created `scripts/lib/dream/engine-endpoints.ts` with pure helpers for `/__dream_engines` reads and `/__set_dream_engine` writes.
* Added token validation before write body parsing, a 4 KiB JSON body cap, invalid JSON and invalid payload mapping, sanitized read/write failures, and stable success bodies.
* Exported endpoint helpers through `scripts/lib/dream/index.ts`.

**Files Changed**:

* `scripts/lib/dream/engine-endpoints.ts` - added read/write endpoint helper layer.
* `scripts/lib/dream/index.ts` - exported endpoint helpers.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T006 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T006 complete and updated progress.

**Verification**:

* Command/check: `bunx tsc --noEmit -p tsconfig.scripts.json --pretty false`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: no compiler diagnostics were emitted after adding endpoint helpers.
* Command/check: `bun --eval 'import { mkdtempSync, rmSync } from "node:fs"; ...'`
  * Result: PASS - endpoint smoke check covered safe read, invalid token, valid write, and invalid engine id.
  * Evidence: command returned `{"read":{"status":200,"ok":true,"selected":"codex"},"denied":403,"written":{"ok":true,"selectedEngineId":"codex","selectedSource":"request","persisted":true},"invalid":400}`.
* Command/check: `rg -n "handleDreamEnginesReadEndpoint|handleSetDreamEngineEndpoint|DREAM_ENGINE_WRITE_MAX_BODY_BYTES|engine-endpoints" scripts/lib/dream/engine-endpoints.ts scripts/lib/dream/index.ts`
  * Result: PASS - read/write helpers, body cap, and barrel export are present.
  * Evidence: matches found in `engine-endpoints.ts` and `index.ts`.
* UI product-surface check: N/A - pure endpoint helper task.
* UI craft check: N/A - pure endpoint helper task.

**BQC Fixes**:

* Trust boundary enforcement: write helper checks token before parsing body and validates engine ids through the config parser (`scripts/lib/dream/engine-endpoints.ts`).
* Failure path completeness: all helper failures return explicit status and safe error bodies (`scripts/lib/dream/engine-endpoints.ts`).
* Error information boundaries: config and write failures return stable sanitized messages without stack traces or paths (`scripts/lib/dream/engine-endpoints.ts`).

### Task T007 - Wire selected-engine resolution into AI OS Dream execution

**Started**: 2026-06-30 00:37 **Completed**: 2026-06-30 00:40 **Duration**: 3 minutes

**Notes**:

* Updated `executeDream()` to read the selected engine from AI OS config, legacy config, explicit request context, or the `codex` auto default before creating the provider runtime.
* Added explicit supported-engine runtime config mapping through `createDreamEngineRuntimeConfig()`.
* Added `unsupported-engine` execution failure behavior for legacy upstream-only engines instead of silently falling back to another provider.
* Preserved the existing activation gates, aggregate refresh, post-aggregate material gates, scheduler-held lock behavior, timeout handling, validation, fallback, continuity, and output write flow.
* Updated the dashboard Dream runner to print only a safe selected-engine label before invoking the existing scheduler job path.

**Files Changed**:

* `scripts/lib/dream/contracts.ts` - added `unsupported-engine` execution failure code.
* `scripts/lib/dream/execution.ts` - resolved selected engine and created runtime from selected-engine config.
* `scripts/dashboard-dream-run.ts` - added safe selected-engine status text before scheduler run.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T007 runtime proof.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T007 complete and updated progress.

**Verification**:

* Command/check: `bunx tsc --noEmit -p tsconfig.scripts.json --pretty false`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: no compiler diagnostics were emitted after execution wiring.
* Command/check: `bun run test -- scripts/lib/__tests__/dream-execution.test.ts scripts/lib/__tests__/scheduler-dream-handler.test.ts`
  * Result: PASS - existing Dream execution and scheduler handler tests passed.
  * Evidence: 2 test files passed; 12 tests passed.
* Command/check: `rg -n "resolveSelectedEngine|createDreamEngineRuntimeConfig|unsupported-engine|selected engine|runtimeFactory" scripts/lib/dream/execution.ts scripts/dashboard-dream-run.ts scripts/lib/dream/contracts.ts`
  * Result: PASS - selected-engine runtime wiring and unsupported-engine branch are present.
  * Evidence: matches found in `execution.ts`, `contracts.ts`, and `dashboard-dream-run.ts`.
* UI product-surface check: N/A - script runtime task.
* UI craft check: N/A - script runtime task.

**BQC Fixes**:

* Trust boundary enforcement: execution uses validated engine ids from config helpers or typed request context (`scripts/lib/dream/execution.ts`).
* Failure path completeness: unsupported legacy engines now return an explicit failed result with safe recovery copy instead of falling through to another provider (`scripts/lib/dream/execution.ts`).
* Contract alignment: runtime factory now receives the selected-engine AI runtime config, preserving one selected-engine source for scheduled and dashboard runs (`scripts/lib/dream/execution.ts`).

### Task T008 - Add guarded Dream engine middleware

**Started**: 2026-06-30 00:40 **Completed**: 2026-06-30 00:42 **Duration**: 2 minutes

**Notes**:

* Added `/__dream_engines` middleware in `vite.config.ts` using existing local control-plane loopback and Host-header validation.
* Added `/__set_dream_engine` middleware using the same local guard and the existing per-dev-server `X-Claude-OS-Token` before reading the request body.
* Routed both middlewares through the pure endpoint helpers from `scripts/lib/dream/engine-endpoints.ts`.
* Added no-store JSON responses with `X-Content-Type-Options: nosniff`.

**Files Changed**:

* `vite.config.ts` - registered Dream engine read/write middleware and local JSON/body helpers.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T008 endpoint evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T008 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics.
* Command/check: `rg -n "__dream_engines|__set_dream_engine|sendDreamEngineJson|readDreamEngineRequestBody|handleDreamEnginesReadEndpoint|handleSetDreamEngineEndpoint" vite.config.ts`
  * Result: PASS - middleware routes and helper calls are present.
  * Evidence: matches found for imports, JSON helper, body helper, `/__dream_engines`, and `/__set_dream_engine`.
* UI product-surface check: N/A - local middleware task.
* UI craft check: N/A - local middleware task.

**BQC Fixes**:

* Trust boundary enforcement: both routes require local control-plane validation, and writes require the refresh token before request body parsing (`vite.config.ts`).
* Failure path completeness: route failures return explicit safe JSON status bodies through endpoint helpers (`vite.config.ts`).
* Error information boundaries: middleware does not return paths, env values, stack traces, or raw config data (`vite.config.ts`).

***

### Task T009 - Create Dream engines client hook

**Started**: 2026-06-30 00:42 **Completed**: 2026-06-30 00:45 **Duration**: 3 minutes

**Notes**:

* Created `src/lib/use-dream-engines.ts` with React Query fetching for `/__dream_engines`.
* Added typed safe endpoint shapes, payload validation, loading, empty, error, offline, saving, save-failed, ready, and public-demo states.
* Added token lookup and token-gated save through `/__set_dream_engine`.
* Added duplicate-save prevention with an in-flight ref, optimistic selected-engine cache update, and query invalidation after save.
* Added browser online/offline listeners so local bridge controls are disabled while offline.

**Files Changed**:

* `src/lib/use-dream-engines.ts` - added Dream engine readiness and selection hook.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T009 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T009 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics.
* Command/check: `rg -n "useDreamEngines|DreamEnginesState|saveEngine|DREAM_ENGINES_QUERY_KEY|__dream_engines|__set_dream_engine" src/lib/use-dream-engines.ts`
  * Result: PASS - hook state machine, query key, fetch endpoint, write endpoint, and save API are present.
  * Evidence: matches found for hook exports, states, read/write endpoints, and `saveEngine`.
* UI product-surface check: N/A - hook-only task.
* UI craft check: N/A - hook-only task.

**BQC Fixes**:

* Duplicate action prevention: `saveEngine` ignores duplicate saves while an engine write is in flight (`src/lib/use-dream-engines.ts`).
* State freshness on re-entry: hook refetches through React Query and invalidates engine readiness after a successful save (`src/lib/use-dream-engines.ts`).
* Failure path completeness: hook exposes explicit offline, error, save-failed, and public-demo states (`src/lib/use-dream-engines.ts`).

***

### Task T010 - Extend Dream run controls for selected-engine context

**Started**: 2026-06-30 00:45 **Completed**: 2026-06-30 00:48 **Duration**: 3 minutes

**Notes**:

* Extended `useDreamRun()` with selected-engine id and label context for Dream run requests and recovery copy.
* Added a `blocked` state so callers can prevent Dream runs when no ready engine is selected while preserving existing duplicate-trigger prevention through the in-flight ref.
* Added endpoint failure recovery copy for expired local control tokens, unsupported engines, and engine setup/auth failures.
* Updated `DreamRunButton` with a blocked-state label while preserving the existing compact/default button patterns.

**Files Changed**:

* `src/lib/use-dream-run.ts` - added selected-engine request context, blocked state, and mapped recovery copy.
* `src/components/dream-run-button.tsx` - added blocked-state button label handling.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T010 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T010 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics after the hook and button changes.
* Command/check: `bun run test -- src/lib/__tests__/use-dream-run.test.tsx`
  * Result: PASS - focused Dream run hook tests passed.
  * Evidence: 1 test file passed; 7 tests passed.
* Command/check: `rg -n "DreamRunOptions|blocked|selectedEngineId|mapDreamRunFailure|blockedLabel" src/lib/use-dream-run.ts src/components/dream-run-button.tsx`
  * Result: PASS - selected-engine options, blocked state, recovery mapper, and button label are present.
  * Evidence: matches found in `src/lib/use-dream-run.ts` and `src/components/dream-run-button.tsx`.
* UI product-surface check: N/A - hook and reusable button behavior only; dashboard/home mounting is covered by later UI tasks.
* UI craft check: N/A - no route-mounted UI changed in this task.

**BQC Fixes**:

* Duplicate action prevention: the in-flight ref still suppresses duplicate Dream run triggers while a request is active (`src/lib/use-dream-run.ts`).
* Failure path completeness: expired-token, unsupported-engine, and setup/auth failures now return caller-visible recovery copy (`src/lib/use-dream-run.ts`).
* Contract alignment: selected-engine request context uses the shared `DreamEngineId` client type and sends a typed JSON body only when a selected engine exists (`src/lib/use-dream-run.ts`).

### Task T011 - Extend setup config shape, defaults, draft persistence, and step titles

**Started**: 2026-06-30 00:49 **Completed**: 2026-06-30 00:57 **Duration**: 8 minutes

**Notes**:

* Added a browser-safe `dream.engine.selectedEngineId` mirror to the setup `ConfigShape`.
* Added setup Dream engine ids, the `codex` default engine, and inserted the "Dream engine" step immediately after "Dream cadence".
* Added setup config helpers for default Dream config, draft read/write, installed persistence through shared keys, and validation of draft engine ids and selection sources.
* Updated the Dream cadence step to preserve the engine mirror when cadence settings are edited.

**Files Changed**:

* `src/components/setup/types.ts` - added setup Dream engine id/source types and nested Dream engine config.
* `src/components/setup/constants.ts` - inserted the Dream engine step and setup engine constants.
* `src/components/setup/config-helpers.ts` - added Dream defaults, draft hydration, draft persistence, and installed-config normalization.
* `src/components/setup/step-dream.tsx` - reused the shared Dream default shape so cadence edits keep `dream.engine`.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T011 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T011 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics after the setup config shape and constants changes.
* Command/check: `rg -n "SetupDreamEngineId|dream\\?:|engine\\?:|SETUP_DREAM_DEFAULT_ENGINE_ID|SETUP_DREAM_ENGINE_IDS|DREAM_ENGINE_STEP_INDEX|STEP_TITLES|persistSetupDraftConfig|readSetupDraftConfig|getDefaultDreamConfig" src/components/setup/types.ts src/components/setup/constants.ts src/components/setup/config-helpers.ts src/components/setup/step-dream.tsx`
  * Result: PASS - setup type, default, draft, and step-title wiring are present.
  * Evidence: matches found in `types.ts`, `constants.ts`, `config-helpers.ts`, and `step-dream.tsx`.
* UI product-surface check: PASS - setup step label is product-facing "Dream engine"; no private paths, raw tokens, env values, or debug labels were added to visible setup copy.
* UI craft check: PASS - step count follows the existing setup Stepper pattern and keeps the Dream engine step adjacent to Dream cadence.

**BQC Fixes**:

* Contract alignment: browser setup config now mirrors the private config shape under `dream.engine.selectedEngineId` without adding upstream raw storage keys (`src/components/setup/types.ts`, `src/components/setup/config-helpers.ts`).
* Trust boundary enforcement: draft hydration validates parsed JSON shape and engine/source enum values before using browser-local draft data (`src/components/setup/config-helpers.ts`).
* State freshness on re-entry: setup can now read an existing `ai-os-config-draft` and normalize it with current Dream defaults (`src/components/setup/config-helpers.ts`).

### Task T012 - Create setup Dream engine step

**Started**: 2026-06-30 00:50 **Completed**: 2026-06-30 00:57 **Duration**: 7 minutes

**Notes**:

* Created `StepDreamEngine` using the Dream engines hook for local readiness, save, retry, offline, error, empty, no-ready, and public-demo states.
* Added ready-only engine selection, save-and-continue behavior through the token-gated hook, and no-ready "Choose later" recovery.
* Mirrored draft selection into setup config as `selectedSource: "draft"` and persisted successful saves as `selectedSource: "request"`.
* Added focus placement on the selected option and arrow-key movement across ready/selectable engine options.

**Files Changed**:

* `src/components/setup/step-dream-engine.tsx` - added the setup Dream engine selection step.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T012 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T012 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics with the new setup step.
* Command/check: `rg -n "StepDreamEngine|Choose later|Save and continue|Dream engine selection|aria-checked|ArrowDown|ArrowRight|saveEngine|refetch" src/components/setup/step-dream-engine.tsx`
  * Result: PASS - setup step, save/retry controls, radiogroup semantics, and keyboard handlers are present.
  * Evidence: matches found for the component, no-ready recovery action, save action, ARIA state, arrow keys, and hook calls.
* UI product-surface check: PASS - visible copy explains the product choice and recovery actions without exposing local paths, tokens, raw config names, or implementation diagnostics.
* UI craft check: PASS - the step follows the existing setup modal card density, icons, status tones, focus rings, and responsive one/two-column option grid.

**BQC Fixes**:

* Duplicate action prevention: engine saves go through `useDreamEngines().saveEngine`, which blocks duplicate writes while an engine save is in flight (`src/components/setup/step-dream-engine.tsx`, `src/lib/use-dream-engines.ts`).
* Accessibility and platform compliance: engine options use `role="radiogroup"`/`role="radio"`, `aria-checked`, focus placement, and arrow-key movement across ready engines (`src/components/setup/step-dream-engine.tsx`).
* Failure path completeness: loading, error, offline, empty, save-failed, no-ready, and public-demo states all render controlled recovery copy (`src/components/setup/step-dream-engine.tsx`).

***

### Task T013 - Wire setup modal to render Dream engine step

**Started**: 2026-06-30 00:54 **Completed**: 2026-06-30 00:57 **Duration**: 3 minutes

**Notes**:

* Wired `StepDreamEngine` into `StepContent` at step 7 and moved `StepYoureSet` to step 8.
* Hydrated setup state from `ai-os-config-draft` before falling back to fresh defaults.
* Routed cancel and autosave draft writes through `persistSetupDraftConfig()`.
* Hid the modal footer Next button on the Dream engine step so ready-engine save, no-ready skip, and retry states remain owned by the step itself.
* Stopped clearing the setup draft from `StepWelcome`, preserving cancel/resume continuity while still clearing transient just-installed and scan markers.

**Files Changed**:

* `src/components/setup/setup-modal.tsx` - rendered the Dream engine step and centralized draft read/write behavior.
* `src/components/setup/step-welcome.tsx` - preserved setup draft continuity on welcome.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T013 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T013 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics after modal routing changes.
* Command/check: `rg -n "StepDreamEngine|readSetupDraftConfig|persistSetupDraftConfig|DREAM_ENGINE_STEP_INDEX|isDreamEngineStep|step === 8" src/components/setup/setup-modal.tsx src/components/setup/step-welcome.tsx`
  * Result: PASS - modal routing, draft hydration/persistence, footer suppression, and finish step index are present.
  * Evidence: matches found in `setup-modal.tsx`; draft removal is absent from `step-welcome.tsx`.
* UI product-surface check: PASS - modal flow now shows product-facing Dream cadence then Dream engine then finish, without exposing debug controls or raw endpoint details.
* UI craft check: PASS - footer behavior avoids a conflicting generic Next action on the engine step and lets the step present state-specific controls.

**BQC Fixes**:

* State freshness on re-entry: setup state now hydrates from a normalized draft before building fresh defaults (`src/components/setup/setup-modal.tsx`, `src/components/setup/config-helpers.ts`).
* Duplicate action prevention: the engine step owns its save control while the parent footer Next is hidden for that step, preventing bypassed duplicate write attempts (`src/components/setup/setup-modal.tsx`).
* Failure path completeness: cancel and autosave draft writes share the same guarded persistence helper (`src/components/setup/setup-modal.tsx`, `src/components/setup/config-helpers.ts`).

***

### Task T014 - Create dashboard Dream engine control

**Started**: 2026-06-30 00:58 **Completed**: 2026-06-30 01:03 **Duration**: 5 minutes

**Notes**:

* Created `DreamEngineControl` for the home dashboard.
* The control reads engine readiness with `useDreamEngines()`, saves ready/selectable engine switches through the token-gated hook, and triggers Dream through `useDreamRun()` with selected-engine context.
* Added Connect/Generate labels, health-aware copy, selected-engine chips, refresh behavior, save/run busy states, and failure recovery copy.
* The primary Generate action is blocked when no ready engine is selected, preserving duplicate-trigger prevention through the Dream run hook.

**Files Changed**:

* `src/components/home/dream-engine-control.tsx` - added dashboard engine switcher and health-aware Generate control.
* `src/components/home/types.ts` - added `DreamHealthProjection` used by the control.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T014 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T014 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics after adding the dashboard control.
* Command/check: `rg -n "DreamEngineControl|useDreamEngines|useDreamRun|selectedEngine|Connect Dream|Generating Dream|engineChipClass" src/components/home/dream-engine-control.tsx src/components/home/types.ts`
  * Result: PASS - component, engine hook, Dream run hook, selected-engine context, Connect/Generate copy, and engine chip handling are present.
  * Evidence: matches found in `dream-engine-control.tsx` and `types.ts`.
* UI product-surface check: PASS - dashboard copy uses product terms such as Dream engine, Connect Dream, and Generate Dream; no raw endpoints, local paths, or debug status names are visible.
* UI craft check: PASS - control is a compact operational dashboard section with icon buttons, engine chips, clear busy states, and responsive wrapping.

**BQC Fixes**:

* Duplicate action prevention: generation uses `useDreamRun()` and engine saves use `useDreamEngines().saveEngine()`, both of which block duplicate in-flight writes (`src/components/home/dream-engine-control.tsx`).
* Contract alignment: selected-engine id and label are passed into the selected-engine-aware Dream run hook (`src/components/home/dream-engine-control.tsx`).
* Failure path completeness: no-ready-engine, public-demo, engine load/save errors, and Dream run errors render caller-visible recovery copy (`src/components/home/dream-engine-control.tsx`).

***

### Task T015 - Mount Dream engine and health projections on home

**Started**: 2026-06-30 01:00 **Completed**: 2026-06-30 01:03 **Duration**: 3 minutes

**Notes**:

* Added `deriveDreamHealthProjection()` so home data projects Dream health states into product-facing titles, details, action labels, tones, and sanitized fix hints.
* Threaded `dreamHealth` through `useHomeData()` and mounted `DreamEngineControl` between the existing Dream hero and Dream sources strip.
* Updated `DreamHero` to consume Dream health copy and removed the generic run button from the hero so generation goes through the engine-aware dashboard control.
* Replaced local scheduler command empty-state copy with product-facing first-run/stale/silent-failure copy.

**Files Changed**:

* `src/lib/home-transforms.ts` - derived Dream health projection and returned it with Dream data.
* `src/lib/use-home-data.ts` - included `dreamHealth` in the home data hook result.
* `src/routes/index.tsx` - mounted `DreamEngineControl` beside the existing Dream dashboard surfaces.
* `src/components/home/dream-hero.tsx` - rendered health-aware product copy and removed the generic run control.
* `src/components/home/types.ts` - added the health projection interface used by home surfaces.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T015 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T015 complete and updated progress.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics after home projection and route changes.
* Command/check: `rg -n "deriveDreamHealthProjection|dreamHealth|DreamHealthProjection|Generate your first Dream Review|Dream Review is due|Dream needs attention|DreamEngineControl dreamHealth|DreamSourcesStrip" src/lib/home-transforms.ts src/lib/use-home-data.ts src/routes/index.tsx src/components/home/dream-hero.tsx src/components/home/types.ts`
  * Result: PASS - health projection, home hook threading, route mount, and hero copy are present.
  * Evidence: matches found in `home-transforms.ts`, `use-home-data.ts`, `index.tsx`, `dream-hero.tsx`, and `types.ts`.
* UI product-surface check: PASS - first-run, stale, silent-failure, generated-review, and public-demo hero/control copy use product-facing language rather than scheduler-command-only instructions.
* UI craft check: PASS - the new control sits in the existing Dream dashboard area before source readiness and keeps a dense dashboard layout.

**BQC Fixes**:

* Product surface discipline: local scheduler command strings were removed from the normal Dream hero empty state (`src/components/home/dream-hero.tsx`).
* Contract alignment: `DreamHealthProjection` keeps live-data `healthStatus` mapped to UI-safe copy before route rendering (`src/lib/home-transforms.ts`).
* Failure path completeness: stale and silent-failure states now have visible dashboard recovery copy and action labels (`src/lib/home-transforms.ts`, `src/components/home/dream-engine-control.tsx`).

***

### Task T016 - Add Dream engine config and endpoint script tests

**Started**: 2026-06-30 01:04 **Completed**: 2026-06-30 01:06 **Duration**: 2 minutes

**Notes**:

* Added config tests for selection parsing, auto-selection, readiness projection, legacy config reads, AI OS write preservation, file mode, runtime config mapping, and unsupported engines.
* Added endpoint-helper tests for safe reads, token-gated writes, token-before-body parsing, invalid JSON, invalid engine ids, body size limits, and sanitized read/write failures.

**Files Changed**:

* `scripts/lib/__tests__/dream-engine-config.test.ts` - added Dream engine config coverage.
* `scripts/lib/__tests__/dream-engine-endpoints.test.ts` - added endpoint-helper coverage.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T016 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T016 complete and updated progress.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-engine-config.test.ts scripts/lib/__tests__/dream-engine-endpoints.test.ts`
  * Result: PASS - focused script tests passed.
  * Evidence: 2 test files passed; 9 tests passed.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` emitted no diagnostics.
* UI product-surface check: N/A - script test task.
* UI craft check: N/A - script test task.

**BQC Fixes**:

* Trust boundary enforcement: tests prove token validation happens before body parsing and invalid engine ids are rejected (`scripts/lib/__tests__/dream-engine-endpoints.test.ts`).
* Error information boundaries: tests prove endpoint failures return safe messages without temp-root path leakage (`scripts/lib/__tests__/dream-engine-endpoints.test.ts`).
* Contract alignment: tests prove config parsing, projections, and runtime-provider mapping match the declared engine contract (`scripts/lib/__tests__/dream-engine-config.test.ts`).

***

### Task T017 - Add selected-engine Dream execution tests

**Started**: 2026-06-30 01:06 **Completed**: 2026-06-30 01:08 **Duration**: 2 minutes

**Notes**:

* Extended Dream execution tests to prove persisted AI OS config selects the OpenAI API runtime for scheduled execution.
* Added dashboard override coverage proving explicit `selectedEngineId` uses Codex before persisted config.
* Added unsupported legacy-engine coverage proving OpenRouter fails with `unsupported-engine` without invoking the runtime factory or leaking keys.
* Added scheduler handler coverage proving scheduled runs leave selected-engine resolution inside Dream execution and do not set a dashboard override.

**Files Changed**:

* `scripts/lib/__tests__/dream-execution.test.ts` - added selected-engine config, dashboard override, and unsupported-engine tests.
* `scripts/lib/__tests__/scheduler-dream-handler.test.ts` - added scheduled selected-engine boundary assertion.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T017 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T017 complete and updated progress.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-execution.test.ts scripts/lib/__tests__/scheduler-dream-handler.test.ts`
  * Result: PASS - focused Dream execution and scheduler tests passed.
  * Evidence: 2 test files passed; 16 tests passed.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` emitted no diagnostics.
* UI product-surface check: N/A - script test task.
* UI craft check: N/A - script test task.

**BQC Fixes**:

* Contract alignment: tests prove selected-engine config is adapted to the expected AI runtime provider config (`scripts/lib/__tests__/dream-execution.test.ts`).
* Failure path completeness: tests prove unsupported legacy engines return explicit failure instead of silent runtime fallback (`scripts/lib/__tests__/dream-execution.test.ts`).
* Error information boundaries: unsupported-engine test verifies provider key text is not serialized in the failure result (`scripts/lib/__tests__/dream-execution.test.ts`).

***

### Task T018 - Add setup, hook, and dashboard UI tests

**Started**: 2026-06-30 01:09 **Completed**: 2026-06-30 01:17 **Duration**: 8 minutes

**Notes**:

* Updated setup modal tests for the new Dream cadence -> Dream engine -> finish step order, token-gated engine save, persisted `dream.engine` config, and env-backed read-only setup flow.
* Added `useDreamEngines` hook tests for loading, ready, empty, error, offline, public-demo, save success, and save failure states.
* Extended `useDreamRun` tests to cover selected-engine request bodies, blocked no-ready-engine runs, and selected-engine failure recovery copy.
* Added dashboard Dream engine control tests for Connect/Generate states, engine switching, in-flight duplicate prevention, stale/silent-failure health copy, and public-demo read-only controls.
* Updated Dream hero and home transform tests for first-run product copy, stale/silent-failure projections, and generated-review health rendering.

**Files Changed**:

* `src/routes/__tests__/setup-modal.test.tsx` - updated setup flow tests and local Dream engine bridge fetch mocks.
* `src/lib/__tests__/use-dream-engines.test.tsx` - added Dream engine readiness and save-state hook coverage.
* `src/lib/__tests__/use-dream-run.test.tsx` - added selected-engine, blocked, and failure-copy Dream run coverage.
* `src/components/home/__tests__/dream-engine-control.test.tsx` - added dashboard control coverage.
* `src/components/home/__tests__/dream-hero.test.tsx` - updated hero assertions for engine-aware product copy.
* `src/lib/__tests__/home-transforms.test.ts` - added Dream health projection assertions.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T018 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T018 complete and updated progress.

**Verification**:

* Command/check: `bun run test -- src/routes/__tests__/setup-modal.test.tsx src/lib/__tests__/use-dream-engines.test.tsx src/lib/__tests__/use-dream-run.test.tsx src/components/home/__tests__/dream-engine-control.test.tsx src/components/home/__tests__/dream-hero.test.tsx src/lib/__tests__/home-transforms.test.ts`
  * Result: PASS - focused setup, hook, dashboard, hero, and transform tests passed.
  * Evidence: 6 test files passed; 110 tests passed.
* UI product-surface check: PASS - tests assert product-facing first-run, stale, silent-failure, Connect Dream, Generate Dream, and public-demo copy without local scheduler-command instructions.
* UI craft check: PASS - tests cover step-owned save flow, accessible engine radios, disabled duplicate generation, and hosted-demo disabled controls.

**BQC Fixes**:

* Failure path completeness: loading, empty, error, offline, public-demo, save-failed, no-ready, stale, and silent-failure states are all covered by focused tests.
* Duplicate action prevention: dashboard tests prove in-flight Dream generation stays disabled through hook state (`src/components/home/__tests__/dream-engine-control.test.tsx`).
* Contract alignment: tests prove selected engine ids flow through setup persistence, save endpoints, and Dream run request bodies (`src/routes/__tests__/setup-modal.test.tsx`, `src/lib/__tests__/use-dream-run.test.tsx`).

***

### Task T019 - Run targeted Dream engine integration tests

**Started**: 2026-06-30 01:17 **Completed**: 2026-06-30 01:18 **Duration**: 1 minute

**Notes**:

* Ran the exact targeted script and UI integration test command listed in `tasks.md`.
* Covered Dream engine config, endpoint helpers, selected-engine execution, scheduler handler boundaries, setup modal flow, engine hook states, Dream run hook states, dashboard control, and Dream hero rendering.

**Files Changed**:

* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T019 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T019 complete and updated progress.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-engine-config.test.ts scripts/lib/__tests__/dream-engine-endpoints.test.ts scripts/lib/__tests__/dream-execution.test.ts scripts/lib/__tests__/scheduler-dream-handler.test.ts src/routes/__tests__/setup-modal.test.tsx src/lib/__tests__/use-dream-engines.test.tsx src/lib/__tests__/use-dream-run.test.tsx src/components/home/__tests__/dream-engine-control.test.tsx src/components/home/__tests__/dream-hero.test.tsx`
  * Result: PASS - targeted Dream engine integration suite passed.
  * Evidence: 9 test files passed; 74 tests passed.
* UI product-surface check: PASS - the targeted suite includes setup, dashboard control, and hero product copy coverage.
* UI craft check: PASS - the targeted suite includes engine step accessibility, dashboard disabled states, and duplicate-trigger prevention coverage.

**BQC Fixes**:

* Regression protection: targeted integration tests now cover both script/runtime boundaries and browser-facing Dream engine surfaces.
* Contract alignment: test evidence spans config, endpoint, scheduler, setup, hook, and dashboard selected-engine behavior.

### Task T020 - Run final quality gates and ASCII/LF validation

**Started**: 2026-06-30 01:18 **Completed**: 2026-06-30 01:21 **Duration**: 3 minutes

**Notes**:

* Ran final lint and typecheck gates after completing the Dream engine integration tests.
* The first lint run found Prettier drift plus one empty-interface lint issue and one hook dependency warning; fixed those by converting the endpoint read options to a type alias, memoizing derived engine hook values, and formatting touched source/test files.
* Reran lint, app typecheck, script typecheck, and the targeted Dream engine test suite after the lint cleanup.
* Validated ASCII and LF line endings across all changed and newly added session files.

**Files Changed**:

* `scripts/lib/dream/engine-endpoints.ts` - changed empty read endpoint options interface to a type alias.
* `src/lib/use-dream-engines.ts` - stabilized empty engine data and memoized derived engine hook values.
* Session source/test files - formatted with Prettier after lint reported formatting drift.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/implementation-notes.md` - recorded T020 evidence.
* `.spec_system/specs/phase38-session07-dream-engine-product-integration/tasks.md` - marked T020 and completion checklist complete.

**Verification**:

* Command/check: `bun run lint`
  * Result: PASS - ESLint completed with exit code 0 after lint cleanup.
  * Evidence: final `eslint .` run emitted no diagnostics.
* Command/check: `bun run typecheck`
  * Result: PASS - app TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit` emitted no diagnostics.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - script TypeScript compilation completed with exit code 0.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` emitted no diagnostics.
* Command/check: `bun run test -- scripts/lib/__tests__/dream-engine-config.test.ts scripts/lib/__tests__/dream-engine-endpoints.test.ts scripts/lib/__tests__/dream-execution.test.ts scripts/lib/__tests__/scheduler-dream-handler.test.ts src/routes/__tests__/setup-modal.test.tsx src/lib/__tests__/use-dream-engines.test.tsx src/lib/__tests__/use-dream-run.test.tsx src/components/home/__tests__/dream-engine-control.test.tsx src/components/home/__tests__/dream-hero.test.tsx`
  * Result: PASS - targeted Dream engine integration suite passed after lint cleanup.
  * Evidence: 9 test files passed; 74 tests passed.
* Command/check: per-file ASCII/LF validation over `git status --short --untracked-files=all`
  * Result: PASS - changed and newly added files are ASCII encoded with LF line endings.
  * Evidence: validation reported `ASCII/LF validation passed for 37 files`.
* UI product-surface check: PASS - final checked code keeps browser copy safe and product-facing.
* UI craft check: PASS - final checked code keeps setup/dashboard controls accessible, stable, and duplicate-action guarded.

**BQC Fixes**:

* State freshness on re-entry: `useDreamEngines()` now uses stable empty data and memoized derived values for hook dependency correctness (`src/lib/use-dream-engines.ts`).
* Contract alignment: endpoint read options now use a type alias rather than an empty interface (`scripts/lib/dream/engine-endpoints.ts`).
* Test/quality completeness: final lint, typecheck, script typecheck, targeted tests, and ASCII/LF validation all pass.
