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 configurable structured logging with request IDs, HTTP context, adapter details, masking, and output formats.
    • Improved correlation across API, database, migration, and service events.
    • Enhanced transaction handling for resource operations.
  • Documentation

    • Expanded logging, configuration, troubleshooting, tracing, masking, and database guidance.
    • Clarified that tracing.enabled is active and the legacy telemetry setting is deprecated.
  • Bug Fixes

    • Improved error reporting and stack-trace behavior.
    • Preserved request context during masking and status processing.

Walkthrough

The pull request replaces the local logging implementation with Go log/slog and shared hyperfleet-logger integration. It adds configurable API logger construction, shared request and adapter context fields, structured logging across commands and packages, and context-aware masking. It updates service transaction and context handling, removes obsolete logger APIs and tests, and expands logging and tracing documentation. New tests cover logger configuration, correlation fields, stack traces, and context propagation.

true. I've added the adapter name to the context. we can distinguish between adapters now by request_id + adapter
