internal/application/service/knowledge.go had grown to 9883 lines /
149 functions spanning CRUD, document processing, summary/question
generation, clone/move, FAQ (CRUD+import+index+export), wiki cleanup,
multimodal image, and file utilities. Navigating it, or diffing
changes in it, was increasingly painful.
Purely mechanical split into 8 files in the same package. No
signatures, behaviors, or types were modified. knowledgeService
struct, NewKnowledgeService, and package-level errors remain in
knowledge.go unchanged. Per-file imports were trimmed by goimports.
knowledge.go 497 struct + constructor + errs + CRUD reads + Search
knowledge_create.go 1144 CreateFrom{File,URL,Passage,Manual} + helpers
knowledge_delete.go 686 Delete + wiki cleanup + ProcessKnowledgeListDelete
knowledge_process.go 2407 ProcessDocument/Summary/Question + Reparse + UpdateImageInfo
knowledge_clone_move.go 1049 Clone* + Move* + progress persistence
knowledge_faq.go 1932 FAQ CRUD + Search + Export
knowledge_faq_import.go 1939 FAQ import/validate/index + runningFAQImportInfo
knowledge_util.go 352 file-type/url/hash + VLM+Storage config + resolveFileService
Verification: go build, go vet, gofmt on the 8 files, and
golangci-lint all clean (22 issues post-split matches 22 pre-split
in knowledge.go — no new issues introduced). The pre-existing
unused warnings on getVLMConfig / buildStorageConfig were left as-is
rather than removing dead code beyond the scope of this task.
