& Mission + +The **MySQLTuner Autonomous Issue Triage System** provides an automated, reproducible, and verifiable engineering pipeline for triaging, diagnosing, reproducing, and resolving GitHub issues submitted to the `jmrenouard/MySQLTuner-perl` repository. + +### Key Tenets +1. **Maintainer Shield**: Tickets authored by maintainer `@jmrenouard` are strictly held (`triage:maintainer-review`) and never auto-closed with canned responses. +2. **Deterministic Verification**: Every resolution must generate a real, standalone Perl `Test::More` test file (`tests/test_issue_XXX.t`) executing structured subtests. +3. **Traceability**: All comments, closures, and diagnostic reports reference exact commit SHAs, reproducible shell scripts, and official DBMS documentation. +4. **Resilient Ingestion**: Cascading multi-transport architecture (GraphQL v4 $\rightarrow$ REST v3 $\rightarrow$ `gh` CLI $\rightarrow$ Offline Replay). +5. **Zero-Dependency Core**: All client code adheres to standard Python 3.10+ library modules and Perl Core modules. + +--- + +## 2. 🧩 6-Module Subsystem Architecture + +```mermaid +graph TD + A["GitHub Issue Webhook /

Safety & Governance"] + F --> G["Module 6: Orchestrator & CLI"] + G --> H["GitHub API / CI Artifacts"] +``` + +### Module 1: Ingestion & Sanitizer (`build/issue_triage/github_ingest.py`, `sanitizer.py`) +- Sanitizes ANSI escape sequences and dangerous HTML. +- Redacts sensitive secrets (AWS keys, GitHub tokens, MySQL credentials, private keys). +- Manages rate-limiting with exponential jitter backoff and checkpoint pagination. + +### Module 2: Analysis & Diagnostic Engine (`build/issue_triage/diagnostic_engine.py`) +- **Taxonomy Resolver**: Disambiguates MySQL, MariaDB (including `5.5.5-` prefix), Percona, Aurora, RDS, and Cloud SQL. +- **Expert Diagnostics**: + - Memory Footprint & OOM Risk Calculator (`memory_footprint_calculator.py`) + - InnoDB Buffer Pool & Instances Sizing (`innodb_expert_diagnostics.py`) + - Table Cache & System File Descriptors (`table_cache_diagnostics.py`) + - HA & Replication Topologies (Galera, Async, Semi-Sync) (`ha_replication_diagnostics.py`) + - Security, TLS & Authentication (`security_auth_diagnostics.py`) + - Performance Schema & Query Profiling (`pfs_query_diagnostics.py`) + - Variable Deprecation Lifecycle Matrix (`deprecation_matrix.py`) + +### Module 3: Test Generation & Proof Validation (`build/issue_triage/test_generator.py`) +- Synthesizes compliant Perl `Test::More` scripts with structured `subtest` blocks. +- Validates syntax via `perl -c` and execution via `Test::Harness` / `prove`. +- Generates reproducible Docker multi-DB scenarios (`docker_scenario_generator.py`). + +### Module 4: Contextual Synthesis & Formatter (`build/issue_triage/response_synthesizer.py`) +- Formats structured Markdown replies with warm community gratitude for third-party developers. +- Generates copy-pasteable `my.cnf` / `mariadb.conf.d` configuration snippets with rationale comments. +- Embeds verifiable test links anchored to specific Git commit SHAs. + +### Module 5: Governance & Invariant Safety Checklist (`build/issue_triage/pre_closing_checklist.py`, `closing_governance.py`) +- Audits 7 hard invariants before any mutation or closure: + 1. `INVARIANT_AUTHOR_NON_MAINTAINER` + 2. `INVARIANT_SYNTAX_VALID` + 3. `INVARIANT_TEST_PASSING` + 4. `INVARIANT_DOC_LINK_PRESENT` + 5. `INVARIANT_RESPONSE_NON_EMPTY` + 6. `INVARIANT_COMMIT_PINNED` + 7. `INVARIANT_SANITIZATION_PASSED` + +### Module 6: CLI & Workflow Orchestrator (`build/issue_triage/triage_orchestrator.py`, `.github/workflows/issue_triage.yml`) +- Provides unified CLI with `--dry-run`, `--issue`, `--offline`, `--repo`, and `--sync-upstream`. +- Seamlessly integrates with GitHub Actions for automated event-driven triage. + +--- + +## 3. 🔄 Upstream Synchronization (`major/MySQLTuner-perl`) + +Per project governance rules, every modification and new feature developed for `jmrenouard/MySQLTuner-perl` can be cross-synchronized with the upstream `major/MySQLTuner-perl` repository: +- **Assignee Rule**: All synchronized upstream issues are automatically assigned to `@jmrenouard`. +- **Classification & Tags**: Commits and pull requests are mapped to upstream labels (`bug`, `enhancement`, `documentation`, `performance`, `db:mysql84`, `db:mariadb114`). +- **Cross-Referenced Proofs**: Upstream responses link directly to verifiable test proof artifacts (`tests/test_issue_XXX.t`) and Git commit SHAs in `jmrenouard/MySQLTuner-perl`. +- **Maintainer Shield**: Issues created by `@jmrenouard` in `major/MySQLTuner-perl` maintain the maintainer shield (`triage:maintainer-review`) and are protected against automated closing. + +--- + +## 4. 💻 Developer Commands & Usage + +```bash +# Run all Python and Perl issue triage unit tests +make test-triage + +# Run issue triage in dry-run mode on downstream
