charset=UTF-8 Content-Transfer-Encoding: 8bit - Add owner_id context plumbing and per-user RAG filtering (prevent poisoning) - Add ownerFilter with UUID validation and pre-computed SQL filters - Reduce MaxKnowledgeContentSize 50KB→10KB, add MaxKnowledgeTitleLength 500 - Add owner_id column to documents table (migration 000003) - Enhance system prompt with thinking partner, emotional awareness, current_date - Add prompt verification integration test (49 scenarios) - Consolidate CI: remove standalone gofmt/gosec, add cross-platform build, fuzz, dependabot - Downgrade expected-failure logs from Error→Warn - Add proposals 014 (pgvector memory R2), 015, 016 and architecture docs --- .github/dependabot.yml | 13 + .github/workflows/ci.yml | 167 +-- .github/workflows/fuzz.yml | 31 + .../000003_add_document_owner.down.sql | 2 + .../000003_add_document_owner.up.sql | 6 + internal/api/chat.go | 5 + internal/chat/chat.go | 3 +- internal/chat/prompt_verification_test.go | 1197 +++++++++++++++++ internal/rag/constants.go | 2 +- internal/tools/context.go | 23 + internal/tools/knowledge.go | 82 +- internal/tools/knowledge_test.go | 104 ++ internal/tools/system.go | 9 +- prompts/koopa.prompt | 172 ++- 14 files changed, 1675 insertions(+), 141 deletions(-) create mode 100644 .github/dependabot.yml create mode 100644 .github/workflows/fuzz.yml create mode 100644 db/migrations/000003_add_document_owner.down.sql create mode 100644 db/migrations/000003_add_document_owner.up.sql create mode 100644 internal/chat/prompt_verification_test.go create mode 100644 internal/tools/context.go diff --git a/.github/dependabot.yml b/.github/dependabot.yml new file mode 100644 index 0000000..22e9ef9 --- /dev/null +++ b/.github/dependabot.yml @@ -0,0 +1,13 @@ +version: 2 +updates: + - package-ecosystem: gomod + directory: / + schedule: + interval: weekly + open-pull-requests-limit: 5 + + - package-ecosystem: github-actions + directory: / + schedule: + interval: weekly + open-pull-requests-limit: 5 diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index d80971e..eff57aa 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -19,23 +19,8 @@ jobs: with: go-version: "1.25" - - name: Run gofmt - run: | - if [ "$(gofmt -l . | wc -l)" -gt 0 ];
