The ticket assumed the API was already fully slog-native. It still used a local logging abstraction, unlike Sentinel, Adapter, and Broker. This PR removes that layer and aligns the API with the shared direct-slog approach.

Summary

  • Replace the local logging handlers and fluent API with context-aware log/slog backed by hyperfleet-logger.
  • Centralize component=api, version/hostname enrichment, correlation fields, text sanitization, and stack-trace policy.
  • Apply loaded logging configuration to bootstrap, serve, and migrate while retaining the HYPERFLEET_LOGGING_* contract.
  • Keep API-specific request ID, HTTP attributes, request-header/body masking, and GORM adapters.
  • Update logging/configuration documentation, contract tests, and generated Helm documentation.

Verification

  • make verify-all — static checks, lint, build, and 1,631 unit tests passed.
  • Helm chart suite — all 27 scenarios passed.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added shared structured logging with request IDs, HTTP context, configurable output, sanitization, and stack-trace handling.
    • Improved logging consistency across API requests, database operations, authentication, migrations, telemetry, and service lifecycle events.
  • Documentation

    • Expanded logging guidance, configuration precedence, masking, tracing, OpenTelemetry setup, troubleshooting, and testing documentation.
    • Clarified that tracing.enabled is preferred while logging.otel.enabled remains deprecated for compatibility.
  • Bug Fixes

    • Preserved error context and structured fields across warnings and failures, improving diagnostics without changing request or shutdown behavior.

Walkthrough

The pull request migrates application logging from the local logger implementation to shared hyperfleet-logger handlers and Go log/slog. Command startup now parses shared logging settings. Context fields use shared request, trace, span, and resource helpers. API, database, middleware, service, telemetry, and test paths emit structured slog records. The old logger and text handler implementations are removed. Documentation covers configuration precedence, masking, request IDs, HTTP fields, GORM logging, tracing, and testing.

Users relying on the deprecated tracing setting may configure the wrong environment variable, but the implementation remains operational and the correction is localized.

Does this context have the previous adapter attribute? I am just wondering how we can distinguish between concurrent adapter reports
