- Update all callers (worker/config.go, tui/config.go, tui/cli_config.go, tui/main.go)
- Update CHANGELOG.md with recent WebSocket handler improvements

[Unreleased]

Security

  • Native: fix buffer overflow vulnerabilities in dataset_hash (replaced strcpy with strncpy + null termination)
  • Native: fix unsafe memcpy in queue_index priority queue (added explicit null terminators for string fields)
  • Native: add path traversal protection in queue_index storage (rejects .. and null bytes in queue directory paths)
  • Native: add mmap size limits (100MB max) to prevent unbounded memory mapping exposure
  • Native: modularize C++ libraries with clean layering (common, queue_index, dataset_hash)

Added

  • API/WebSocket: add dataset handlers (list, register, info, search) with DB integration
  • API/WebSocket: add metrics persistence to handleLogMetric with websocket_metrics table
  • Storage: add db_metrics.go with RecordMetric, GetMetrics, GetMetricSummary methods
  • Tests: add payload parsing tests for WebSocket handlers

Changed

  • Config: replace panic() with error returns in smart_defaults.go for better error handling
  • Tests: move WebSocket handler tests to tests/unit/api/ws/

Fixed

  • Storage: remove duplicate db_datasets.go, consolidate with db_experiments.go

Deprecated

  • Config: ToTUIConfig() now returns (*Config, error) instead of *Config

Removed

  • Storage: deleted internal/storage/db_datasets.go (duplicate implementation)
