+## Inspur/Kaytus parser notes
+
+- Base hardware inventory comes from `asset.json` + `component.log` + `devicefrusdr.log`.
+- Additional runtime enrichment is applied from `redis-dump.rdb` (if present):
+  - GPU serial/firmware/UUID and selected runtime metrics;
+  - NIC firmware/serial/part fields where text logs are incomplete.
+- GPU/NIC enrichment from Redis is conservative (fills missing fields, avoids unsafe remapping).
+
+### External PCI IDs lookup (no hardcoded model mapping)
+
+`internal/parser/vendors/pciids` now loads IDs from a repo file
+(`internal/parser/vendors/pciids/pci.ids`, embedded at build time) plus optional external overrides.
+
+Lookup priority:
+1. embedded `internal/parser/vendors/pciids/pci.ids`,
+2. `./pci.ids`,
+3. `/usr/share/hwdata/pci.ids`,
+4. `/usr/share/misc/pci.ids`,
+5. `/opt/homebrew/share/pciids/pci.ids`,
+6. `LOGPILE_PCI_IDS_PATH` (highest priority overrides; supports path list).
+
+Implication:
+- for unknown device IDs (e.g. new NVIDIA GPU IDs), model naming can be updated via `pci.ids`
+  without changing parser code.
