-
logging-observability
Structured JSON logging with correlation IDs, request context propagation across async boundaries, performance timing decorators, and worker metrics collection.

-
exception-taxonomy
Hierarchical exception system with HTTP status codes, machine-readable error codes, and structured responses for consistent API error handling across all endpoints.

-
error-sanitization
Production-safe error handling that logs full details server-side while exposing only generic, safe messages to users. Prevents information leakage of database strings, file paths, stack traces, and API keys.

-
validation-quarantine
Data validation with quality scoring and quarantine for suspicious records. Validates incoming data without blocking the pipeline, enabling manual review of edge cases.
dadbodgeoff/drift 770
-
error-handling
Implement consistent error handling with custom error classes, error boundaries, and structured error responses. Covers logging, monitoring, and user-friendly messages.

-
typescript-strict
Configure TypeScript strict mode with additional safety flags. Catch bugs at compile time instead of production. Includes branded types, exhaustive switches, and Result types.

-
caching-strategies
Implement multi-layer caching with Redis, in-memory, and HTTP caching. Covers cache invalidation, stampede prevention, and cache-aside patterns.

-
tier-entitlements
Implement subscription tier-based feature gating and usage limits. Centralized tier configuration, database usage tracking, and clean APIs for checking limits.

-
batch-processing
Collect-then-batch pattern for database operations achieving 30-40% throughput improvement. Includes graceful fallback to sequential processing when batch operations fail.

-
pwa-setup
Progressive Web App setup with manifest, mobile meta tags, safe area handling for notched devices, and install prompts for app-like browser experience.

-
backpressure
Manage data flow when producers outpace consumers. Bounded buffers, adaptive flushing, and graceful degradation prevent OOM crashes and data loss.
dadbodgeoff/drift 770
-
provenance-audit
AI generation provenance and audit trail tracking. Records decision factors, data lineage, reasoning chains, confidence scoring, and cost tracking for AI-generated content.
dadbodgeoff/drift 770
-
background-jobs
Implement robust background job processing with dead letter queues, retries, and state machines. Use when building async workflows, scheduled tasks, or any work that shouldn't block the request/response cycle.

-
prompt-engine
Template-based AI prompt engine with YAML templates, brand kit injection, input sanitization for security, and token-efficient context blocks.

-
health-checks
Implement health check endpoints for load balancers, Kubernetes, and monitoring. Covers liveness, readiness, and dependency checks.
dadbodgeoff/drift 770
-
graceful-shutdown
Clean shutdown with in-flight job tracking, signal handlers, and buffer draining. Prevent data loss and corrupted state on process termination.
dadbodgeoff/drift 770
-
graceful-degradation
Build resilient systems that degrade gracefully under failure. Implement fallbacks, feature flags, and partial responses when dependencies fail.
dadbodgeoff/drift 770
-
dead-letter-queue
Store failed jobs for replay or manual inspection. Track failure patterns, enable manual intervention, and prevent data loss from processing errors.
dadbodgeoff/drift 770
-
database-migrations
Safe database migration strategies for zero-downtime deployments. Covers backward-compatible changes, data migrations, and rollback procedures.
