Artifact and media metadata were previously reconstructed from job result
refs and JSON sidecar files. This change regularizes metadata into SQLite,
keeps filesystem blobs in place, and preserves backward compatibility via
lazy fallback and backfill from existing job refs and JSON metadata.
Constraint: Blob storage remains on the local filesystem in this phase
Rejected: Migrate blobs into SQLite | larger scope and worse operational profile for current media sizes
Rejected: Hard cutover without fallback | unsafe for historical data already on the test server
Confidence: medium
Scope-risk: moderate
Directive: Treat SQLite as the metadata source of truth; JSON sidecars are compatibility fallback only
Tested: go test ./...; deployed to test server 101.42.99.35; verified /v1/artifacts, /v1/artifacts/:id, signed media URL 200, unsigned content 401
Not-tested: Full historical backfill sweep over all existing artifact rows under production-sized data volume
The server now resolves source, identity, and style artifacts separately, emits role-labeled Gemini parts, and logs the effective request shape so deployed debugging can confirm which references reached upstream.
Constraint: The test deployment must stay on gemini-3.1-flash-image-preview while gaining better multi-image editing semantics
Rejected: Change the default model to gemini-3-pro-image-preview | test-server parity required keeping flash as default
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Preserve the source/identity/style logging until the upstream gateway exposes equivalent structured traces
Tested: go test ./internal/server
Tested: image img2img against http://101.42.99.35:18080/v1 (job_5af212df2c27)
Not-tested: Non-Gemini multi-image providers still fall back to the first reference only
The server now keeps portable image ratio normalization, enforces documented Seedream size presets, routes MiniMax img2img through generations-style payloads, and submits Hailuo video variants through the video generations API with proper reference-image handling.
Constraint: The deployed test chain relies on popiartServer as the lowest-risk place to adapt provider-specific routing without broad newapi changes
Rejected: Expand newapi relay modes for every MiniMax image/video branch | larger blast radius than needed for the verified server-managed flows
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep MiniMax-specific media routing in popiartServer unless upstream newapi adapters are upgraded to the same contract
Tested: go test ./internal/server -run TestInferRouteKeyForModelRecognizesViduAsVideo|TestGenerate|TestResolve|TestSubmitMiniMaxVideoTask|TestExecuteImageToImageJobUsesGenerationsPathForMiniMax|TestExecuteImageToVideoJob|TestResolveVideoReferencesSupportsImagesArray
Not-tested: Full PopiNewAPI unit suite (blocked earlier by external module checksum drift in local checkout)
Direct `models/infer` image requests were defaulting to `image.text2image`, which dropped reference inputs and produced unrelated generations. Route image-edit payloads to `image.img2img`, accept canonical `image` URLs during reference resolution, and preserve reference-aware prompt hints.
Constraint: The test server must continue accepting both canonical `image` and legacy alias fields from callers already in circulation
Rejected: Fix only reference URL parsing | direct overrides would still be misrouted as text2image before reference resolution runs
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Any future image-model route inference must inspect input shape before defaulting to text2image
Tested: `env GOCACHE=/tmp/popiartserver-gocache go test ./internal/server -run 'TestInferRouteKeyForModelRecognizesViduAsVideo|TestInferRouteKeyForModelRecognizesImageEditInputs|TestResolveImageToImageReferenceAcceptsCanonicalImageURL|TestGenerateEditedImageRefsUsesSeedreamImagesGenerationsEndpoint'`; deployed to `101.42.99.35` and verified Seedream gateway requests include `image`
Not-tested: Full manual validation against every non-Seedream image-edit provider
