Brings together: image ingestion +(PNG/JPG/HEIC/AVIF) with `gbrain import` materializing `image`-type pages, +`voyage-multimodal-3` embeddings into a new `embedding_image vector(1024)` column with +partial HNSW index, `gbrain query --image ` for image-to-image and image-to-text +search, OCR pass via the configured expansion model with prompt-injection mitigation, +and PGLite parity for the `files` table that v0.18 deferred. + +### To take advantage of v0.28.9 + +`gbrain upgrade` should do this automatically.

New `MultimodalInput` discriminated + union type. Voyage recipe declares `supports_multimodal: true` for + `voyage-multimodal-3`. +- **Schema migration v39** (`multimodal_dual_column_v0_27_1`) — adds + `content_chunks.modality TEXT NOT NULL DEFAULT 'text'`, `embedding_image + vector(1024)`, partial HNSW index `idx_chunks_embedding_image WHERE + embedding_image IS NOT NULL`, widens `pages.page_kind` CHECK to admit + `'image'`. PGLite gains the `files` table (parity catch-up). Pre-flight + refuses if pgvector < 0.5.0 with an actionable upgrade hint. +- **`PageType` gains `'image'`** plus `ALL_PAGE_TYPES` const + `assertNever` + exhaustiveness helper. CI guard `scripts/check-pagetype-exhaustive.sh` + prevents silent default-branch fall-through on union growth. +- **`gbrain query --image `** — new CLI flag for image-to-X search via + the multimodal vector index. New tests in `test/cli-query-image.test.ts` + + `test/query-image-flag.serial.test.ts` + `test/search-image-column.test.ts`. +- **OCR pass** — `gateway.generateOcrText()` extracts visible text from + ingested images via the configured expansion model, with explicit + system-prompt mitigation against OCR-as-prompt-injection. Opt-in via + `gbrain config set embedding_image_ocr true`. +- **Image decoder bundle** — `src/types/image-decoders.d.ts` types the + embedded decoder set. CI guard `scripts/check-image-decoders-embedded.sh` + enforces every supported format ships in the binary. +- **Test coverage** — 9 new test files covering import-image-file pipeline, + multimodal-postgres E2E, voyage-multimodal recipe, engine.upsertFile API, + loadConfig DB-plane merge, page-type exhaustiveness, schema-bootstrap + coverage extension. ~1.5K lines of new test code. + +### For contributors + +- `BrainEngine` gains `upsertFile`, `getFile`, `listFilesForPage`. `FileSpec` / + `FileRow` types exported from `src/core/engine.ts`. +- `src/core/embedding.ts` re-exports `embedMultimodal` and `MultimodalInput` + for callers that want to pull both text and image embedding APIs from the + same module. +- Multimodal migration is `v39` (renumbered from the original v34 / v36 + on the embedding-providers branch — master had claimed those slots for + `destructive_guard_columns` (v34), `auto_rls_event_trigger` (v35), and + `subagent_provider_neutral_persistence_v0_27` (v36)). + ## [0.28.7] - 2026-05-06 ## **Voyage backfill no longer infinite-loops on dense payloads.
