# Specification: Strategic Technical Evolutions

- **Feature Name**: Strategic Technical Evolutions
- **Status**: Draft
- **Created Date**: 2026-06-23

## 🧠 Rationale

As MySQLTuner-perl matures, maintaining release integrity, documentation synchronization, and developer workflow stability becomes as critical as the advisor logic itself. The "Strategic Technical Evolutions" address the governance, automation, and localization of the project's ecosystem. By implementing strict validation gates, automated release scripts, and documentation sanity checks, we ensure that the single-file tool is backed by robust, industrial-grade quality assurance processes.

## 🛠️ User Scenarios

### Scenario 1: CI/CD & Documentation Integrity
A contributor submits a pull request introducing a new advisor warning. They update the `README.md` and `ROADMAP.md` but copy-paste a broken reference link. 
The CI/CD pipeline triggers the **Reference Link Availability Checker** and the **Roadmap Schema Validator**, identifies the exact file and line number of the broken link, and fails the build. The developer corrects the link, and the build passes.

### Scenario 2: Automated & Fail-Safe Release Lifecycle
The Release Manager decides to cut version `v2.9.1`. Instead of manually editing version strings in six separate locations and running python generator scripts, they execute the **Interactive Release Orchestrator**:
1. The tool prompts: `Select version bump type: [major, minor, micro]`.
2. The user chooses `micro`.
3. The orchestrator automatically bumps the version from `v2.9.0` to `v2.9.1`, updates the 6 reference locations, parses the Git commit history to generate the release note in `releases/v2.9.1.md`, and populates the `Executive Summary` in the `Changelog`.
4. Before tagging, the **Release Artifact Validator** scans the new release file to ensure the structure matches standard markdown syntax.

### Scenario 3: Pre-Commit Quality Guard
A developer edits `mysqltuner.pl` to add support for a new MySQL 9.x variable (a `feat` type commit). They attempt to run `git commit`. 
The **Automated Changelog Formatting Verification** hook intercepts the commit, notices that a `feat` modification in the script was staged, but `Changelog` was not modified. The commit is rejected with a message reminding the developer to document their changes in `Changelog`.

## 📋 User Stories

| Title | Priority | Description | Rationale | Test Case |
| :--- | :--- | :--- | :--- | :--- |
| **1. Reference Link Auditor** | P2 | As a developer, I want a pipeline command to scan documentation files | To automatically prevent dead or broken URLs/paths in help files. | **GIVEN** a markdown file contains a broken link, **WHEN** the auditor runs, **THEN** it outputs a list of broken URLs/files with line numbers and exits with code 1. |
| **2. Dynamic Help Anchors** | P2 | As a DBA, I want unique reference anchors displayed alongside advisor recommendations | To quickly navigate to detailed documentation in the official database KB. | **GIVEN** MySQLTuner suggests changing a parameter, **WHEN** it runs, **THEN** it outputs an anchor like `[REF: INNODB-BP]` mapping to official KBs. |
| **3. Localized References** | P3 | As a non-English speaker, I want references in my own language | To understand advice without translation overhead. | **GIVEN** localized output is selected (e.g. Italian), **WHEN** reference URLs are printed, **THEN** they point to localized KB paths where available. |
| **4. Pre-commit Changelog Hook** | P1 | As a maintainer, I want the pre-commit hook to verify `Changelog` edits on `feat`/`fix` changes | To ensure every functional change is properly documented before commit. | **GIVEN** `mysqltuner.pl` is changed with a `feat`/`fix` intent, **WHEN** committing, **THEN** block the commit if `Changelog` has no staged changes. |
| **5. Containerized Validation** | P1 | As a developer, I want local pre-flight checks to run inside a minimal Docker container | To avoid "works on my machine" issues due to environmental differences. | **GIVEN** local changes are made, **WHEN** running `make test-containerized`, **THEN** execute the unit test suite inside an isolated minimal container. |
| **6. Interactive Orchestrator** | P1 | As a Release Manager, I want a single script to bump versions and run release note generators | To prevent manual synchronization errors across the 6 version reference locations. | **GIVEN** a release is requested, **WHEN** selecting micro/minor/major, **THEN** update `CURRENT_VERSION.txt`, `mysqltuner.pl` (3 references), `Changelog`, and create the release note file. |
| **7. Release Summary Auto-Sync** | P2 | As a Release Manager, I want release summaries automatically extracted from commit logs | To save time and ensure no changes are omitted from release notes. | **GIVEN** commits exist since the last release tag, **WHEN** generating release notes, **THEN** parse and populate the Executive Summary automatically. |
| **8. Release Artifact Validator** | P2 | As a maintainer, I want validation of new release notes syntax and metadata | To prevent malformed or broken release documentation in `releases/`. | **GIVEN** a release file is generated, **WHEN** verified, **THEN** assert it contains mandatory headers, matching version, and valid issue links. |
| **9. Roadmap Syntax Linter** | P3 | As a maintainer, I want structured linting for `ROADMAP.md` | To keep the roadmap file syntactically clean and resolve all spec file paths. | **GIVEN** `ROADMAP.md` is modified, **WHEN** linted, **THEN** check syntax constraints, category mappings, and existence of all specification files. |
| **10. Roadmap Progress Auto-Sync** | P3 | As a developer, I want roadmap checklist items to be marked complete automatically on commit | To reduce manual housekeeping of the roadmap project status. | **GIVEN** a commit with scope `feat(auth):` is merged, **WHEN** roadmap sync is triggered, **THEN** check and mark related checklist items as completed `[x]`. |

## ✅ Verification Plan

### Automated Tests
- **Link Auditor Verification**:
  - Run the auditing script against test fixtures (e.g. `tests/fixtures/good_links.md` and `tests/fixtures/bad_links.md`) and verify the exit codes.
- **Git pre-commit Hook Verification**:
  - Simulate staging a `feat: add feature` commit without modifying `Changelog` and check if git blocks the commit.
- **Version Orchestration Verification**:
  - Run the orchestrator in dry-run mode (`--dry-run`) to verify that the version variables are correctly computed and replaced in a mock directory structure.
- **Docker Validation Runner**:
  - Run `make test-containerized` and confirm the suite successfully executes inside a temporary Docker container and tears down cleanly.
- **Linter & Schema Verification**:
  - Execute markdown schema validation scripts against `ROADMAP.md` and `releases/*.md` to confirm formatting compliance.

### Manual Verification
- Execute `--help` and verify that documentation references are listed and dynamically generated.
- Run the localized script (e.g., with environment configuration) to verify translation mapping of reference domains.
