# V1 Block 01 — Project Foundation

Status: Completed

Purpose: Establish a clean Dart package foundation, repository conventions, and starter test loop. This block should leave the repository easy for Codex to modify safely.

## Chunk 1.1 — Verify project scaffold

Recommended Codex level: low

Status: Completed with environment blocker noted

Tasks:

- Inspect `pubspec.yaml`, `analysis_options.yaml`, `README.md`, and `.gitignore`.
- Confirm the repo is a pure Dart package, not a Flutter app yet.
- Confirm `lib/scheduler_core.dart` exports only stable public entry points.
- Confirm `lib/src/` contains implementation files.
- Confirm `test/` contains at least one starter test.

Acceptance criteria:

- `dart pub get` succeeds, or any dependency issue is documented.
- `dart analyze` succeeds, or initial scaffold issues are fixed.
- `dart test` succeeds, or the failure is fixed.

Execution notes:

- Verified `pubspec.yaml`, `analysis_options.yaml`, `README.md`, and `.gitignore`.
- Confirmed the repository is currently structured as a pure Dart package, not a Flutter app.
- Confirmed `lib/scheduler_core.dart` exports the starter public entry points from `lib/src/`.
- Confirmed `lib/src/` contains implementation files and `test/` contains a starter scheduling engine test.
- Could not run `dart pub get`, `dart analyze`, or `dart test` because neither `dart` nor `flutter` is installed on `PATH` in this environment.
- Commit was deferred until the repository was initialized and repaired.

## Chunk 1.2 — Stabilize public API boundaries

Recommended Codex level: medium

Status: Completed with environment blocker noted

Tasks:

- Keep public exports in `lib/scheduler_core.dart` minimal.
- Ensure internal helpers remain under `lib/src/`.
- Add comments that identify which APIs are starter placeholders.
- Do not add Flutter UI code in this block.

Acceptance criteria:

- Public API is small and understandable.
- Internal implementation is not accidentally exported beyond current needs.
- Analyzer and tests pass.

Execution notes:

- Kept `lib/scheduler_core.dart` exports limited to the existing starter model, scheduling engine, and statistics surfaces.
- Confirmed implementation remains under `lib/src/`.
- Added public documentation comments that identify the starter placeholder APIs without changing scheduling behavior.
- Did not add Flutter UI code.
- Could not run `dart analyze` or `dart test` because neither `dart` nor `flutter` is installed on `PATH` in this environment.
- Commit was deferred until the repository was initialized and repaired.

BREAKPOINT: Stop here if the next requested chunk changes Codex level.

## Chunk 1.3 — Document local development commands

Recommended Codex level: low

Status: Completed with environment blocker noted

Tasks:

- Update `README.md` with setup, analyze, test, and project layout notes if missing.
- Do not duplicate the full product spec in README.
- Keep human/product detail in `Human Documentation/`.
- Keep execution detail in `Codex Documentation/`.

Acceptance criteria:

- README tells a new contributor how to run checks.
- README points Codex/humans to the correct documentation folders.

Execution notes:

- Updated `README.md` with the Dart SDK prerequisite, local setup/check commands, and when to run them.
- Added documentation boundary notes for `Human Documentation/`, `Codex Documentation/Current Software Plan/`, and `Codex Documentation/Archived plans/`.
- Did not duplicate the full product spec in `README.md`.
- Could not run `dart analyze` or `dart test` because neither `dart` nor `flutter` is installed on `PATH` in this environment.
- Commit was deferred until the repository was initialized and repaired.
