# Requirements Document

## Introduction

The PyPI publishing workflow is failing when triggered by GitHub releases, preventing automated package publishing. Manual publishing works, but automated release-triggered publishing does not. This spec addresses the root cause analysis and resolution of the publishing pipeline failure.

## Glossary

- **GitHub Actions Workflow**: Automated CI/CD pipeline that runs on GitHub events
- **PyPI Publishing**: Process of uploading Python packages to the Python Package Index
- **Release Trigger**: GitHub release event that should automatically trigger package publishing
- **Quality Gates**: Automated code quality checks (linting, formatting, type checking, tests)
- **Trusted Publisher**: PyPI's secure authentication method using GitHub Actions OIDC tokens

## Requirements

### Requirement 1

**User Story:** As a maintainer, I want to understand why PyPI publishing fails when triggered by releases, so that I can fix the automated publishing pipeline.

#### Acceptance Criteria

1. WHEN investigating the publishing failure, THE System SHALL identify the exact step where the workflow fails
2. WHEN analyzing workflow logs, THE System SHALL determine if the failure occurs before or during the PyPI publishing step
3. WHEN examining the failure, THE System SHALL document the specific error messages and exit codes
4. THE System SHALL verify whether the PyPI trusted publisher configuration is correct
5. THE System SHALL determine if manual publishing bypasses certain workflow steps that automated publishing does not

### Requirement 2

**User Story:** As a maintainer, I want the automated PyPI publishing to work reliably when I create GitHub releases, so that package distribution is seamless.

#### Acceptance Criteria

1. WHEN a GitHub release is published, THE Publishing_Workflow SHALL execute all quality checks successfully
2. WHEN quality checks pass, THE Publishing_Workflow SHALL authenticate with PyPI using trusted publisher credentials
3. WHEN authentication succeeds, THE Publishing_Workflow SHALL build and upload the package to PyPI
4. THE Publishing_Workflow SHALL complete without errors for release-triggered events
5. THE Publishing_Workflow SHALL produce the same result whether triggered manually or by release events

### Requirement 3

**User Story:** As a maintainer, I want to identify and fix any code quality issues that prevent publishing, so that the quality gates don't block legitimate releases.

#### Acceptance Criteria

1. THE System SHALL identify all linting, formatting, and type checking errors in the codebase
2. WHEN quality issues are found, THE System SHALL fix them according to project standards
3. THE System SHALL ensure all tests pass after quality fixes are applied
4. THE System SHALL verify that quality fixes don't break existing functionality
5. THE System SHALL maintain code quality standards while enabling successful publishing

### Requirement 4

**User Story:** As a maintainer, I want to prevent releases with failing quality checks from being created, so that all published releases are guaranteed to have passing quality gates.

#### Acceptance Criteria

1. THE Release_System SHALL block tag creation when quality checks fail on the target commit
2. WHEN attempting to create a release, THE Release_System SHALL run the same quality checks as the publishing workflow
3. THE Release_System SHALL prevent GitHub release creation unless all required checks pass
4. WHEN quality checks fail during release creation, THE Release_System SHALL provide clear error messages indicating which checks failed
5. THE Release_System SHALL ensure only commits that pass all quality gates can be tagged for release

### Requirement 5

**User Story:** As a maintainer, I want version numbers to be synchronized between git tags and package metadata, so that PyPI publishing never fails due to version conflicts.

#### Acceptance Criteria

1. WHEN creating a release, THE Version_System SHALL validate that the git tag version matches the package version in pyproject.toml
2. WHEN version mismatch is detected, THE Publishing_Workflow SHALL fail fast with a clear error message
3. THE Version_System SHALL prevent duplicate version uploads to PyPI by ensuring version uniqueness
4. WHEN a version already exists on PyPI, THE Publishing_Workflow SHALL provide actionable guidance for version resolution
5. THE Version_System SHALL maintain a single source of truth for version management to prevent synchronization issues
