🔐 DevSecOps

TaipanStack integrates security and quality at every level:

Category	Tools	Purpose
SAST	Bandit, Semgrep + custom rules	Static Application Security Testing
SCA	Safety, pip-audit	Dependency vulnerability scanning
SBOM	Syft (CycloneDX)	Software Bill of Materials
SLSA	Cosign (Sigstore)	Artifact signing & attestation
Types	Mypy (strict)	Compile-time type checking
Lint	Ruff	Lightning-fast linting & formatting
Arch	Import Linter	Dependency rule enforcement
Test	Pytest, Hypothesis, mutmut	Property-based & mutation testing
Perf	pytest-benchmark	Performance regression detection
Containers	Docker (Alpine, rootless)	Hardened-by-default images

CI Pipeline

# Runs on every push/PR
✓ Test Matrix     → Python 3.11-3.14 × (Ubuntu, macOS, Windows)
✓ Linux Distros   → Ubuntu, Debian, Fedora, openSUSE, Arch, Alpine
✓ Code Quality    → Ruff check & format
✓ Type Check      → Mypy strict mode
✓ Security        → Bandit + Semgrep (custom rules)
✓ Architecture    → Import Linter contracts
✓ Benchmarks      → Performance regression (>5% = fail)
✓ SBOM + SLSA     → Supply-chain attestation on release

📚 API Highlights

Result Types (Rust-Style Error Handling)

from taipanstack.core.result import Result, Ok, Err, safe

@safe
def divide(a: int, b: int) -> float:
    return a / b

# Explicit error handling with pattern matching
match divide(10, 0):
    case Ok(value):
        print(f"Result: {value}")
    case Err(error):
        print(f"Error: {error}")

Security Guards

from taipanstack.security.guards import guard_path_traversal, guard_command_injection

# Prevent path traversal attacks
safe_path = guard_path_traversal(user_input, base_dir="/app/data")

# Prevent command injection
safe_cmd = guard_command_injection(
    ["git", "clone", repo_url],
    allowed_commands=["git"]
)

Retry with Exponential Backoff

from taipanstack.utils.retry import retry

@retry(max_attempts=3, on=(ConnectionError, TimeoutError))
async def fetch_data(url: str) -> dict:
    return await http_client.get(url)

Circuit Breaker

from taipanstack.utils.circuit_breaker import circuit_breaker

@circuit_breaker(failure_threshold=5, timeout=30)
def call_external_service() -> Response:
    return service.call()

🔗 Combining Result + Circuit Breaker

from taipanstack.core.result import safe, Ok, Err
from taipanstack.utils.circuit_breaker import CircuitBreaker

breaker = CircuitBreaker(failure_threshold=3, timeout=60, name="payments")

@breaker
@safe
def charge_customer(customer_id: str, amount: float) -> dict:
    return payment_gateway.charge(customer_id, amount)

# Both circuit protection AND explicit error handling
result = charge_customer("cust_123", 49.99)
match result:
    case Ok(receipt):
        print(f"Payment successful: {receipt}")
    case Err(error):
        print(f"Payment failed safely: {error}")

🔗 Combining Result + Retry with Monitoring

from taipanstack.core.result import safe, unwrap_or
from taipanstack.utils.retry import retry

@retry(
    max_attempts=3,
    on=(ConnectionError, TimeoutError),
    on_retry=lambda attempt, max_a, exc, delay: print(
        f"⚠️  Attempt {attempt}/{max_a} failed, retrying in {delay:.1f}s..."
    ),
)
@safe
def fetch_user_profile(user_id: str) -> dict:
    return api_client.get(f"/users/{user_id}")

# Retry handles transient failures, Result handles business errors
profile = unwrap_or(fetch_user_profile("usr_456"), {"name": "Unknown"})

🔗 Adaptive Resilience Pipeline

from taipanstack.core.result import Result, Ok, Err
from taipanstack.resilience.adaptive import ResilienceOrchestrator, AdaptiveCircuitBreaker
from taipanstack.resilience.retry import RetryConfig

# Compose an intelligent pipeline: Bulkhead -> Breaker -> Retry -> Timeout -> Fallback
orch = (
    ResilienceOrchestrator("billing_api")
    .with_bulkhead(max_concurrent=10, max_queue=50) # Prevent resource exhaustion
    .with_circuit_breaker(AdaptiveCircuitBreaker("billing", target_error_rate=0.1)) # Auto-tunes thresholds
    .with_retry(RetryConfig(max_attempts=3, initial_delay=0.1))
    .with_timeout(5.0)
    .with_fallback({"status": "unavailable"})
)

async def process_billing() -> Result[dict, Exception]:
    # The orchestrator handles all concurrency, retry, circuit breaking, and fallbacks
    return await orch.execute(stripe_gateway.charge)

Intelligent Caching

from taipanstack.utils.cache import cached
from taipanstack.core.result import Result

@cached(ttl=60)
async def get_user_data(user_id: int) -> Result[dict, Exception]:
    return await db.fetch(user_id) # Only Ok() results are cached

Fallbacks & Timeouts

from taipanstack.utils.resilience import fallback, timeout
from taipanstack.core.result import Result

@fallback(fallback_value={"status": "offline"}, exceptions=(TimeoutError,))
@timeout(seconds=5.0)
async def fetch_remote_status() -> Result[dict, Exception]:
    return await api.get_status()
