 To provide continuous visibility into the firmware runtime without compromising acoustic deadlines, SOF decouples event generation from data transmission through a multi-tier observability stack:
 
-* **Compile-Time String Metadata Extraction (:ref:`dbg-traces`)**: Format strings and filenames are stripped from the firmware binary by the ``smex`` tool into an external dictionary file (``.ldc``), leaving compact 32-bit entry IDs and packed arguments in firmware text.
+* **Compile-Time String Metadata Extraction (:ref:`dbg-traces`)**: SOF uses the Zephyr logging dictionary
 * **Autonomous Hardware Trace DMA**: Log entries and performance metrics are written to high-speed internal SRAM circular buffers and transferred to host memory windows by background DMA engines without CPU intervention.
 * **Network-Accessible Telemetry Server (:ref:`dbg-probes`)**: High-throughput daemon (``sof_probe_server``) streaming live trace DMA packets over TCP port ``9999`` to remote development clients and the multi-pane ``dut-monitor`` dashboard.
 * **Zero-Allocation Fatal Crash Preservation (:ref:`dbg-coredump-reader`)**: Dedicated hardware memory window backends preserve CPU register windows, call stacks, and exception causes upon fatal CPU traps for GDB post-mortem backtrace analysis.
