Phase 1 • Track 01

1. Data Pipelines & Sub-Generator Streaming (`yield` / `yield from`)

Decouple data production from consumption. Generators stream infinite series, paginate database records, and process multi-gigabyte logs without unbounded RAM allocation.

💡 Senior Engineering Architecture Principles

Lazy Evaluation: Computes items on-demand, holding O(1) memory state regardless of payload length.
Sub-generator Delegation: `yield from` establishes a bidirectional channel forwarding iterators and exception signals.
Memory Safety: Prevents system crash and OutOfMemoryError (OOM) during heavy log or DB ingestion.

⚡ 30-Second Code Quality & Automation Summary

Ruff, Pre-Commit & Strict Static Auditing

Unified Tooling (Ruff): Replaces flake8, black, isort, bandit, and pyupgrade in Rust, running linting and formatting across codebases in sub-millisecond execution times.
Multi-Tiered Safety Net: Combines IDE formatting (<50ms), pre-commit git hooks, and blocking CI pull-request checks.
Strict Static Auditing: Enforces zero-tolerance type safety (mypy --strict) and automated dependency vulnerability scans (pip-audit).

1. Unified Tooling with Ruff Configuration

Consolidate code formatting and linting into a single high-performance Rust engine via pyproject.toml:

# pyproject.toml configuration for Ruff
[tool.ruff]
target-version = "py312"
line-length = 88

[tool.ruff.lint]
select = [
    "E", "W",  # pycodestyle errors & warnings
    "F",       # Pyflakes
    "I",       # isort import ordering
    "B",       # flake8-bugbear (mutable defaults, traps)
    "UP",      # pyupgrade syntax modernization
    "S",       # flake8-bandit security auditing
    "C4",      # flake8-comprehensions efficiency
    "ASYNC",   # flake8-async event loop traps
]

2. The Multi-Tiered Safety Net

Enforce a three-tier quality architecture:

Tier 1: Local IDE Hooks — Instant formatting and lint feedback on save (<50ms).
Tier 2: Pre-Commit Hooks — Fast local scans before git history commits (`.pre-commit-config.yaml`).
Tier 3: CI Gateways — Mandatory GitHub Actions pipelines enforcing mypy --strict, pip-audit, and unit/integration test matrices before code merge.
