Interface + types + in-memory fake only. **No live Vertex calls, no GCP client construction, no I/O**; the real `VertexProvider` is a separate out-of-band slice.\n\n### `ImageProvider` interface\n- Single `Generate(ctx, Request) (Response, error)` method covering **both generate and edit** (an edit is just a generation with reference images present — mirrors the genai SDK, which has no separate edit endpoint).\n- `ctx` first and honored: a cancelled context returns promptly with a context error before any work.\n\n### Types (modeled 1:1 on genai `Part`/`Blob` for a lossless future mapping)\n- `RefImage{Data, MIMEType}` — an input reference image.\n- `Request{Prompt, RefImages, Options, ContinuationToken}`.\n- `Response{Parts, ContinuationToken}` — **ordered parts**, each text and/or an `ImageBlob` (not flattened, so interleaved narration+image survives).\n- `Part` with `TextPart`/`ImagePart` constructors and `IsText`/`IsImage`.\n- `ContinuationToken []byte` — opaque carrier for Gemini's multi-turn thought-signature. Field reserved, **no threading logic built** (keeps the seam stable for the later slice).\n\n### Guards\n- `MaxReferenceImages = 14` (Gemini 3 Pro Image), documented in code.\n- `Request.Validate()` returns the sentinel `ErrTooManyReferenceImages` when exceeded — shared by the fake and the future real impl.\n\n### `FakeProvider` (test vehicle)\n- Returns caller-configured canned `Response`/`Err`, records received requests for assertion.\n- Honors ctx cancellation **before** recording or touching canned work, and enforces the ref-count guard — documenting the contract the real impl must meet.\n\n## Tests (TDD, black-box)\n- fake returns a configured image response (ordered text + image parts, continuation token)\n- fake returns a configured error\n- fake records the requests it was called with (prompt + ref count)\n- cancelled context yields a context error without recording or invoking canned work\n- request over `MaxReferenceImages` rejected with the sentinel; exactly-max allowed\n- table-driven `Request.Validate` boundaries\n\n## Verification\n- `go vet ./...` clean\n- `CGO_ENABLED=1 go test -race -count=1 ./...` green (dispatch env now has gcc)\n- `gofmt` clean\n- `golangci-lint` not installed in-executor — CI is the gate.\n", "head": "feat/imageprovider-interface-fake", "owner": "mathias", "repo": "parallax", "title": "feat: ImageProvider interface + fake (perception/generation seam)"}, "name": "mcp__gitea__pr_create", "turn": 84, "type": "tool_use"}
