### Task T005 - Add readiness-warning logic

**Started**: 2026-06-29 21:20 **Completed**: 2026-06-29 21:21 **Duration**: 1 minute

**Notes**:

* Added `evaluateDreamAuthReadiness()` to recognize Anthropic API key presence, valid Claude setup-token credential evidence, AI OS OpenAI API runtime readiness, AI OS mock runtime readiness, Codex account auth-path evidence, Hermes provider readiness, and loopback Codex app-server endpoint configuration.
* Warning output is bounded to provider/status labels and recovery commands. It does not print token values, bearer headers, credential file contents, raw scheduler logs, or private auth paths.
* Missing-auth guidance lists concrete ready options without claiming readiness from placeholder values.

**Files Changed**:

* `scripts/lib/scheduler/dream-install.ts` - Added readiness classification and safe warning-line generation.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - readiness helper compiles with existing AI runtime, Hermes, Claude credential, and Codex endpoint helpers.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* Command/check: targeted inspection of `evaluateDreamAuthReadiness()` in `scripts/lib/scheduler/dream-install.ts`
  * Result: PASS - warning copy is provider/status-only and uses existing placeholder filtering.
  * Evidence: Ready sources are labels such as "Claude setup-token credential" and "OpenAI API runtime"; missing-auth guidance prints commands only.
* UI product-surface check: N/A - setup/CLI copy only.
* UI craft check: N/A - no UI changed.

**BQC Fixes**:

* Error information boundaries: readiness warnings expose only readiness labels and recovery commands, not credential material or private auth contents (`scripts/lib/scheduler/dream-install.ts`).

***

### Task T004 - Create testable Dream install helper

**Started**: 2026-06-29 21:15 **Completed**: 2026-06-29 21:20 **Duration**: 5 minutes

**Notes**:

* Added `scripts/lib/scheduler/dream-install.ts` for argument parsing, platform context resolution, safe shell/XML/PowerShell/Windows command quoting, macOS plist rendering, Linux cron copy, Windows `.cmd` wrapper rendering, and Task Scheduler command construction.
* Kept the scheduled AI OS sequence centralized as aggregate refresh followed by `scripts/dashboard-dream-run.ts`.
* Added injectable filesystem/spawn dependencies so Windows scheduler behavior can be verified through a faithful harness on non-Windows hosts.

**Files Changed**:

* `scripts/lib/scheduler/dream-install.ts` - New helper for platform-specific Dream scheduler install behavior and command construction.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - scripts TypeScript project compiles after adding the helper.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0 after fixing the duplicate `platform` object field.
* Command/check: targeted inspection of `scripts/lib/scheduler/dream-install.ts`
  * Result: PASS - helper contains Task Scheduler argv, macOS plist, Linux cron, wrapper, and quoting functions.
  * Evidence: `buildWindowsSchedulerCommand`, `buildWindowsWrapperContent`, `buildMacLaunchdPlist`, `buildLinuxCronLine`, `shellSingleQuote`, `powerShellSingleQuote`, and `windowsCmdQuote` are present.
* UI product-surface check: N/A - script/backend helper only.
* UI craft check: N/A - no UI changed.

**BQC Fixes**:

* Failure path completeness: helper returns structured parse errors and scheduler failure descriptions instead of exiting inside parsing or command construction (`scripts/lib/scheduler/dream-install.ts`).

***

### Task T003 - Create evidence file and record selected runner sequence

**Started**: 2026-06-29 21:14 **Completed**: 2026-06-29 21:14 **Duration**: 1 minute

**Notes**:

* Selected scheduled command sequence: `cd <repo> && <bun> run scripts/aggregate.ts ; <bun> run scripts/dashboard-dream-run.ts`.
* The initial aggregate refresh gives Dream current host/local material. The semicolon preserves the existing AI OS recovery behavior where Dream can still attempt its material-first scheduler path after a flaky aggregate refresh.
* `scripts/dashboard-dream-run.ts` is the scheduled Dream runner boundary because it runs the AI OS Dream scheduler job and refreshes live data after new Dream output is written.

**Files Changed**:

* `.spec_system/specs/phase38-session04-dream-scheduling-and-setup/implementation-notes.md` - Added implementation evidence file and selected command sequence.

**Verification**:

* Command/check: `sed -n '1,240p' scripts/dashboard-dream-run.ts`
  * Result: PASS - AI OS Dream runner boundary inspected.
  * Evidence: Script runs `scheduler-runner --job dream` and refreshes aggregate data after successful new Dream output.
* Command/check: `sed -n '1,240p' scripts/scheduler-runner.ts`
  * Result: PASS - scheduler runner entry inspected.
  * Evidence: Dream execution remains inside existing scheduler job contracts and private scheduler state handling.
* UI product-surface check: N/A - script/backend evidence only.
* UI craft check: N/A - no UI changed.

***

### Task T020 - Validate ASCII/LF and record final platform evidence

**Started**: 2026-06-29 21:32 **Completed**: 2026-06-29 21:33 **Duration**: 1 minute

**Notes**:

* Validated ASCII-only and LF-only requirements across touched source, test, documentation, and session files.
* Recorded Windows faithful harness coverage through unit tests because the current host is Linux.
* Recorded macOS plist rendering, Linux cron guidance, and setup-readiness warning cases through targeted tests.

**Files Changed**:

* `.spec_system/specs/phase38-session04-dream-scheduling-and-setup/implementation-notes.md` - Recorded final validation evidence.

**Verification**:

* Command/check: `bunx prettier --check scripts/install-dream-cron.ts scripts/lib/scheduler/dream-install.ts scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts scripts/lib/__tests__/scheduler-operator-status.test.ts scripts/setup.ts scripts/lib/scheduler/operator-status.ts scripts/README_scripts.md`
  * Result: PASS - formatting clean.
  * Evidence: Prettier reported all matched files use Prettier code style.
* Command/check: `rg --pcre2 -n "[^\\x00-\\x7F]" <touched files>`
  * Result: PASS - no non-ASCII matches.
  * Evidence: `rg` exited 1 with no output, meaning no matches were found.
* Command/check: `rg -n "\\r" <touched files>`
  * Result: PASS - no CR line-ending matches.
  * Evidence: `rg` exited 1 with no output, meaning no carriage returns were found in files. Generated Windows `.cmd` content intentionally renders CRLF at runtime from escaped string content.
* Command/check: `git diff --check`
  * Result: PASS - no whitespace errors in tracked diffs.
  * Evidence: command exited 0 with no output.
* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/scheduler-operator-status.test.ts`
  * Result: PASS - Windows harness, macOS plist, Linux fallback, and setup-readiness cases covered.
  * Evidence: Vitest reported 2 files and 28 tests passed.
* Command/check: `bun run test -- scripts/lib/__tests__/scheduler-runner.test.ts scripts/lib/__tests__/dream-execution.test.ts`
  * Result: PASS - scheduler/Dream regressions covered.
  * Evidence: Vitest reported 2 files and 25 tests passed.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - scripts TypeScript project compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* UI product-surface check: N/A - no product-facing UI routes changed.
* UI craft check: N/A - no UI changed.

***

## Final Summary

* Implemented platform-aware AI OS Dream scheduling through macOS launchd, Windows Task Scheduler, and Linux manual cron guidance.
* Scheduled command sequence is aggregate refresh followed by `scripts/dashboard-dream-run.ts`; upstream `scripts/run-dream.ts` and raw `claude -p "/dream"` are not scheduled.
* Added readiness-based setup/auth guidance that recognizes setup-token and configured provider cases without printing credentials.
* Added focused tests for helper command construction, Windows harness actions, status copy safety, and platform CLI candidates.
* Remaining blockers: none.

* UI product-surface check: N/A - script helper tests only.
* UI craft check: N/A - no UI changed.

***

### Task T017 - Assert scheduler setup copy safety

**Started**: 2026-06-29 21:30 **Completed**: 2026-06-29 21:31 **Duration**: 1 minute

**Notes**:

* Scheduler operator-status tests now assert Dream setup copy advertises Windows/macOS/Linux support, includes AI OS runner commands, and omits upstream/raw Claude execution copy and unsafe credential strings.

**Files Changed**:

* `scripts/lib/__tests__/scheduler-operator-status.test.ts` - Added Dream setup/status safety assertions.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/scheduler-operator-status.test.ts`
  * Result: PASS - scheduler setup copy stayed command-only and safe.
  * Evidence: Vitest reported 2 files and 28 tests passed.

***

### Task T019 - Run scheduler/Dream regressions and script typecheck

**Started**: 2026-06-29 21:31 **Completed**: 2026-06-29 21:31 **Duration**: 1 minute

**Notes**:

* Ran scheduler runner and Dream execution regression tests.
* Ran the script TypeScript project typecheck after all script changes.

***

### Task T015 - Align operator status and script documentation

**Started**: 2026-06-29 21:28 **Completed**: 2026-06-29 21:30 **Duration**: 2 minutes

**Notes**:

* Updated Dream scheduler operator copy to advertise macOS launchd, Windows Task Scheduler, and Linux manual cron support.
* Documented the scheduled AI OS runner sequence and Windows query/run actions in `scripts/README_scripts.md`.
* Added a Dream-specific scheduler status test to keep setup copy command-only and browser-safe.

**Files Changed**:

* `scripts/lib/scheduler/operator-status.ts` - Updated Dream install stance and AI OS runner boundary copy.
* `scripts/README_scripts.md` - Documented Dream schedule support and command sequence.
* `scripts/lib/__tests__/scheduler-operator-status.test.ts` - Added Dream setup/status safety assertions.

**Verification**:

***

### Task T014 - Add readiness-based headless-auth setup guidance

**Started**: 2026-06-29 21:26 **Completed**: 2026-06-29 21:28 **Duration**: 2 minutes

**Notes**:

* Setup now prints a dedicated "Dream headless auth readiness" section based on `evaluateDreamAuthReadiness()`.
* Ready cases include Claude setup-token credential evidence, Anthropic API key, AI OS OpenAI API runtime, mock runtime, Codex account auth-path evidence, Hermes provider readiness, and loopback Codex app-server endpoint configuration.
* Missing-auth copy lists setup-token/API/runtime/Codex account recovery options without exposing credential paths or token values.

**Files Changed**:

* `scripts/setup.ts` - Added Dream auth readiness section.
* `scripts/lib/scheduler/dream-install.ts` - Shared readiness helper used by setup and installer.
* `scripts/lib/__tests__/dream-install.test.ts` - Covers setup-token, ready-provider, and missing-auth warning states.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - readiness states covered.
  * Evidence: Tests assert Claude setup-token detection without token output, OpenAI provider readiness, and bounded missing-auth guidance.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - setup readiness integration compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* UI product-surface check: N/A - terminal setup copy only.
* UI craft check: N/A - no UI changed.

**BQC Fixes**:

* Error information boundaries: setup guidance prints readiness labels and commands only, not credential values or private credential file contents (`scripts/setup.ts`, `scripts/lib/scheduler/dream-install.ts`).

***

### Task T013 - Update setup auto-install behavior and copy

**Started**: 2026-06-29 21:26 **Completed**: 2026-06-29 21:28 **Duration**: 2 minutes

**Notes**:

* `scripts/setup.ts` now auto-installs the AI OS Dream schedule on both macOS and Windows.
* Linux remains a manual cron guidance path and points operators to scheduler guidance rather than claiming a failed setup.
* Setup copy now describes "AI OS Dream schedule" instead of macOS-only inherited cron compatibility.

**Files Changed**:

* `scripts/setup.ts` - Updated install branch, setup labels, and automation inventory copy for macOS launchd, Windows Task Scheduler, and Linux manual guidance.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - setup changes compile.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* Command/check: targeted inspection of `scripts/setup.ts`
  * Result: PASS - setup installer branch includes `darwin` and `win32`, with Linux manual skip copy.
  * Evidence: `installDreamCron()` returns "registered via Task Scheduler" for Windows and "loaded via launchctl" for macOS.
* UI product-surface check: N/A - terminal setup copy only.
* UI craft check: N/A - no UI changed.

***

### Task T012 - Correct Linux fallback guidance

**Started**: 2026-06-29 21:23 **Completed**: 2026-06-29 21:25 **Duration**: 2 minutes

**Notes**:

* Linux fallback now prints a manual cron line that changes into the AI OS repo, runs aggregate, then runs `scripts/dashboard-dream-run.ts`.
* Stale copy saying Windows requires manual Task Scheduler setup was removed; Linux guidance now states Windows is auto-installable with `bun run install-dream`.
* Linux `--uninstall` remains manual because the script does not own the user's crontab.

**Files Changed**:

* `scripts/lib/scheduler/dream-install.ts` - Added Linux cron line and fallback copy builder.
* `scripts/install-dream-cron.ts` - Uses Linux fallback copy on non-macOS/non-Windows install.
* `scripts/lib/__tests__/dream-install.test.ts` - Asserted Linux fallback copy.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - Linux fallback copy covered.
  * Evidence: Test asserts `15 8 * * *`, aggregate-before-Dream ordering, Windows auto-installable copy, and absence of `manual-only`/`claude -p`.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - Linux fallback path compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* UI product-surface check: N/A - scheduler CLI only.
* UI craft check: N/A - no UI changed.

***

### Task T011 - Update macOS plist command construction

**Started**: 2026-06-29 21:23 **Completed**: 2026-06-29 21:25 **Duration**: 2 minutes

**Notes**:

* macOS still writes the inherited `com.claude-os.dream` launchd plist, unloads the existing job best-effort, and loads the plist with `launchctl`.
* The plist command now runs `scripts/aggregate.ts` first and `scripts/dashboard-dream-run.ts` second, using the same shell quoting helper as the Linux command.
* Raw `claude -p "/dream"` and upstream `scripts/run-dream.ts` are no longer scheduled.

**Files Changed**:

* `scripts/lib/scheduler/dream-install.ts` - Added AI OS launchd plist rendering.
* `scripts/install-dream-cron.ts` - Preserved launchctl load/unload flow while using helper-rendered plist content.
* `scripts/lib/__tests__/dream-install.test.ts` - Asserted plist command content.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - macOS plist command covered.
  * Evidence: Test asserts `scripts/aggregate.ts ;`, `scripts/dashboard-dream-run.ts`, `com.claude-os.dream`, and absence of `scripts/run-dream.ts`/`claude -p`.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - macOS install path compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* UI product-surface check: N/A - scheduler CLI only.
* UI craft check: N/A - no UI changed.

***

### Task T010 - Implement Windows query, run, and uninstall actions

**Started**: 2026-06-29 21:23 **Completed**: 2026-06-29 21:25 **Duration**: 2 minutes

**Notes**:

* Added Windows `--query`, `--run`, and `--uninstall` action routing in `scripts/install-dream-cron.ts`.
* Query uses `Get-ScheduledTask`, run avoids duplicate starts by returning successfully when the task state is already `Running`, and uninstall exits successfully when the task is absent.
* PowerShell missing or scheduler-command failures map to explicit installer failure copy.

**Files Changed**:

* `scripts/lib/scheduler/dream-install.ts` - Added query/run/uninstall PowerShell command construction and failure descriptions.
* `scripts/install-dream-cron.ts` - Added Windows action dispatch and wrapper cleanup on uninstall.
* `scripts/lib/__tests__/dream-install.test.ts` - Asserted query/run/uninstall argv and missing PowerShell failure copy.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - Windows action harness covered.
  * Evidence: Tests assert `Get-ScheduledTask`, duplicate-running guard, `Start-ScheduledTask`, idempotent unregister copy, and missing PowerShell messaging.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - Windows action routing compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* UI product-surface check: N/A - scheduler CLI only.
* UI craft check: N/A - no UI changed.

**BQC Fixes**:

* Duplicate action prevention: Windows on-demand run checks for an already running task before starting another scheduler run (`scripts/lib/scheduler/dream-install.ts`).
* Failure path completeness: missing PowerShell and command failures produce actionable non-zero failures (`scripts/lib/scheduler/dream-install.ts`, `scripts/install-dream-cron.ts`).

***

### Task T009 - Implement Windows wrapper install/replace behavior

**Started**: 2026-06-29 21:23 **Completed**: 2026-06-29 21:25 **Duration**: 2 minutes

**Notes**:

* Windows install now writes the `.cmd` wrapper to the private inherited Dream state location and registers the `AI OS Dream` scheduled task through PowerShell ScheduledTasks.
* Reinstall is idempotent because the registration command uses `Register-ScheduledTask ... -Force`.
* The wrapper uses CRLF content, changes into the AI OS repo, runs aggregate first, then runs `scripts/dashboard-dream-run.ts`.

**Files Changed**:

* `scripts/lib/scheduler/dream-install.ts` - Added Windows wrapper rendering and install command construction.
* `scripts/install-dream-cron.ts` - Writes wrapper content and executes the Windows install command.
* `scripts/lib/__tests__/dream-install.test.ts` - Asserts wrapper content and install argv.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - Windows wrapper/install harness covered.
  * Evidence: Assertions verify `.cmd` content, `Register-ScheduledTask`, `-Force`, aggregate-first ordering, dashboard Dream runner, and absence of `scripts/run-dream.ts`/`claude -p`.
* Command/check: `bun run typecheck:scripts`
  * Result: PASS - Windows install path compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* UI product-surface check: N/A - scheduler CLI only.
* UI craft check: N/A - no UI changed.

**BQC Fixes**:

* Duplicate action prevention: Windows install uses task replacement rather than creating duplicate scheduled tasks (`scripts/lib/scheduler/dream-install.ts`).

***

### Task T008 - Wire install-dream-cron to helper

**Started**: 2026-06-29 21:23 **Completed**: 2026-06-29 21:25 **Duration**: 2 minutes

**Notes**:

* Replaced the installer entry point with a thin CLI over `scripts/lib/scheduler/dream-install.ts`.
* Preserved exit code 2 for invalid args and exit code 0 for help output.
* Added `--query` and `--run` actions while keeping `--uninstall` and `--time`.

**Files Changed**:

* `scripts/install-dream-cron.ts` - Delegates parsing, platform command rendering, readiness checks, plist/wrapper content, and scheduler command construction to the helper.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - CLI wiring compiles.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` exited 0.
* Command/check: `bun run scripts/install-dream-cron.ts --help`
  * Result: PASS - help output printed supported options and exited 0.
  * Evidence: Output listed `--time`, `--query`, `--run`, `--uninstall`, and `--help`.
* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - helper contract stayed green after CLI wiring.
  * Evidence: Vitest reported 2 files and 20 tests passed.
* UI product-surface check: N/A - CLI/script entry point only.
* UI craft check: N/A - no UI changed.

**BQC Fixes**:

* Failure path completeness: invalid/unsupported CLI actions now fail explicitly with controlled exit codes and copy (`scripts/install-dream-cron.ts`).

***

### Task T006 - Add Dream install unit tests

**Started**: 2026-06-29 21:21 **Completed**: 2026-06-29 21:22 **Duration**: 1 minute

**Notes**:

* Added `scripts/lib/__tests__/dream-install.test.ts` covering strict argument parsing, Windows wrapper content, Task Scheduler install/query/run/uninstall argv, missing PowerShell failure copy, macOS plist command, Linux cron copy, and readiness states.
* Tests assert AI OS scheduled commands use `scripts/aggregate.ts` and `scripts/dashboard-dream-run.ts`, and never schedule upstream `scripts/run-dream.ts` or raw `claude -p`.

**Files Changed**:

* `scripts/lib/__tests__/dream-install.test.ts` - New focused helper tests for Dream scheduler install behavior.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - 2 test files passed.
  * Evidence: Vitest reported 20 tests passed in 204 ms.
* UI product-surface check: N/A - script/helper tests only.
* UI craft check: N/A - no UI changed.

***

### Task T007 - Preserve platform helper expectations

**Started**: 2026-06-29 21:21 **Completed**: 2026-06-29 21:22 **Duration**: 1 minute

**Notes**:

* Added a Windows scheduled-task CLI candidate regression to keep `.bun\\bin`, `%APPDATA%\\npm`, `%LOCALAPPDATA%\\Programs`, and PATHEXT-derived `.cmd` executable resolution stable.
* This protects the Dream scheduler wrapper from accidentally choosing extensionless npm shims on Windows.

**Files Changed**:

* `scripts/lib/__tests__/platform.test.ts` - Added Windows scheduled-task CLI candidate coverage.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/dream-install.test.ts scripts/lib/__tests__/platform.test.ts`
  * Result: PASS - 2 test files passed.
  * Evidence: Vitest reported 20 tests passed in 204 ms.
* UI product-surface check: N/A - platform helper tests only.
* UI craft check: N/A - no UI changed.

### Task T001 - Verify upstream scheduler and setup hunk behavior

**Started**: 2026-06-29 21:13 **Completed**: 2026-06-29 21:13 **Duration**: 1 minute

**Notes**:

* Compared current AI OS `scripts/install-dream-cron.ts` with upstream v2.8.1 `scripts/install-dream-cron.ts` and `scripts/setup.ts`.
* Upstream v2.8.1 adds Windows Task Scheduler install/uninstall through PowerShell and `.cmd` wrapper generation, plus setup auto-install on Windows.
* Upstream scheduled command targets `scripts/run-dream.ts`, which this session must not port directly. AI OS must schedule aggregate refresh followed by `scripts/dashboard-dream-run.ts`.
* Current AI OS installer is still macOS launchd plus Linux guidance and invokes raw `claude -p "/dream"` after aggregate.

**Files Changed**:

* `.spec_system/specs/phase38-session04-dream-scheduling-and-setup/implementation-notes.md` - Created implementation evidence and recorded upstream/current characterization.

**Verification**:

* Command/check: `sed -n '1,620p' /home/aiwithapex/projects/claudeos/claude-os-v2.8.1/scripts/install-dream-cron.ts`
  * Result: PASS - upstream behavior inspected.
  * Evidence: Found Windows Task Scheduler PowerShell registration, `.cmd` wrapper rendering, setup-token warning copy, and upstream `scripts/run-dream.ts` scheduling target.
* Command/check: `sed -n '1,620p' scripts/install-dream-cron.ts`
  * Result: PASS - current AI OS behavior inspected.
  * Evidence: Found macOS-only launchd install, Linux fallback copy, raw `claude -p "/dream"` scheduled command, and stale manual Windows guidance.
* UI product-surface check: N/A - script/backend characterization only.
* UI craft check: N/A - no UI changed.

### Task T002 - Characterize current scheduler setup surfaces

**Started**: 2026-06-29 21:13 **Completed**: 2026-06-29 21:14 **Duration**: 1 minute

**Notes**:

* Current macOS launchd flow writes `~/Library/LaunchAgents/com.claude-os.dream.plist`, unloads existing launchd state best-effort, then loads the plist.
* Current Linux fallback prints a crontab line for raw `claude -p "/dream"` and still says Windows is manual-only.
* Current setup only auto-installs on macOS and labels Dream cron as a macOS launchd compatibility path.
* Current Dream operator status copy says status/setup commands do not install or manage Dream timers.

**Files Changed**:

* `.spec_system/specs/phase38-session04-dream-scheduling-and-setup/implementation-notes.md` - Recorded pre-edit scheduler/setup baseline.

**Verification**:

* Command/check: `sed -n '1,620p' scripts/setup.ts`
  * Result: PASS - setup baseline inspected.
  * Evidence: Found macOS-only `installDreamCron()` branch and setup copy for inherited Dream cron compatibility.
* Command/check: `sed -n '1,620p' scripts/lib/scheduler/operator-status.ts`
  * Result: PASS - Dream operator copy inspected.
  * Evidence: Found Dream install stance and command hints for scheduler run/status with no timer install support.
* Command/check: `sed -n '1,620p' scripts/lib/__tests__/scheduler-operator-status.test.ts`
  * Result: PASS - current status coverage inspected.
  * Evidence: Existing tests cover aggregate and Trend Finder setup safety; Dream-specific setup copy needs additional assertions.
* UI product-surface check: N/A - script/status copy only.
* UI craft check: N/A - no UI changed.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase38-session04-dream-scheduling-and-setup/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
