Popi/NewAPIWG is now the primary gateway, so the UI and request paths need to avoid legacy provider assumptions while keeping local reference media usable for upstream calls. This change aligns model defaults, point display, inline node controls, and temporary reference image handling around that gateway boundary.
Constraint: Upstream providers cannot fetch localhost reference URLs, but large base64 payloads previously caused request/body reliability issues.
Constraint: Seedance point estimates depend on authenticated NewAPIWG /api/points/estimate responses rather than static catalog prices.
Rejected: Send all reference images directly as large data URLs | would reintroduce oversized JSON/request failures.
Rejected: Restore legacy per-provider key controls by default | current product direction is a single Popi/NewAPI gateway.
Confidence: high
Scope-risk: moderate
Directive: Do not pass /api/images localhost URLs to upstream generation APIs; resolve them server-side or fail before the upstream call.

Not-tested: npm run lint fails because next lint is parsed as a missing /lint project directory under Next 16.
Multi-image NewAPIWG generations were sending base64 reference images
inside the /api/generate JSON body. Two ordinary canvas references can
push that payload near the dev/server body boundary, leaving the route
to parse an incomplete JSON string and surface a raw syntax error.
Move large NewAPIWG references through the existing in-memory image
serving path: the browser uploads large data URLs as multipart image
files, sends short /api/images/{id} URLs in the generation request, and
the route resolves those temporary URLs back to server-local image data
before calling providers. The route also turns malformed/truncated JSON
into a readable validation error.
Constraint: Keep provider payload semantics unchanged after /api/generate receives the request
Constraint: Do not rely on request origin matching because Next dev can report 0.0.0.0 while the browser uses localhost
Rejected: Increase body size limits only | still sends multi-MB JSON and does not protect hosted/proxied environments
Rejected: Compress reference images client-side | changes model input fidelity and still leaves large JSON possible

The welcome screen now matches the Popi.TV brand and gives unauthenticated users two explicit paths: jump to the main-site login page or provide a Popi/NewAPI gateway key directly. The manually provided key is persisted in the local user store and forwarded through the NewAPI-backed generation, model, LLM, and chat routes without requiring a login token.
Constraint: Users need a usable local path when they are not logged into the main site.\nRejected: Keep the startup login modal for missing tokens | it blocked the in-welcome login/key choices.\nRejected: Rename internal workflow prompts and storage keys | those are compatibility/internal identifiers, not the visible brand surface.\nConfidence: high\nScope-risk: moderate\nDirective: Keep manual gateway-key access scoped to NewAPI-backed paths; non-NewAPI providers should continue requiring a login token.\nTested: npm run test:run -- src/app/api/models/__tests__/route.test.ts src/app/api/models/[modelId]/__tests__/route.test.ts src/app/api/llm/__tests__/route.test.ts src/app/api/chat/__tests__/route.test.ts src/app/api/generate/__tests__/route.test.ts\nTested: npm run test:run -- src/components/__tests__/QuickstartInitialView.test.tsx src/components/__tests__/WelcomeModal.test.tsx\nTested: npm run build\nTested: Browser verification for Popi.TV welcome title and two unauthenticated entry paths\nTested: git diff --cached --check\nNot-tested: Full test suite\nNot-tested: npm run lint still fails because the existing Next 16 next lint script resolves /lint as a project directory
The default Popi Models image route can return transient upstream overloads for apiyi_nano_banana_2 even when the gateway configuration is valid. The executor now uses gpt-image-2-all as an implicit same-gateway fallback only for overload-shaped errors, while preserving explicit fallback behavior and surfacing non-overload errors unchanged.
Constraint: The gateway can intermittently return system_disk_overloaded for the default image model
Rejected: Change the default model globally | would alter every new image node instead of only recovering transient failures
Rejected: Fallback on every error | would hide prompt, safety, or request-shape problems
Confidence: high
Scope-risk: moderate
Directive: Keep implicit fallback predicates narrow so user-actionable errors remain visible
Tested: npm run test:run

Browser-file-system workflow saves were still bypassing external media storage, so local projects could keep large image, video, and audio data embedded instead of writing refs into the selected browser-backed workspace. The storage path now uses the browser file helpers for image, video, and audio refs and hydrates them back without API calls.
Constraint: Keep local browserfs storage on the existing external media storage path instead of adding a new persistence mode.
Rejected: Keep browserfs excluded from externalization | it preserves the old large-payload behavior for local projects.

Output nodes were collapsing multiple connected media inputs into one visible result, which made image/video/audio/3D connections look ignored. The node now preserves each connected media kind and presents explicit result switching with current/all download actions.
Constraint: Output node remains a result endpoint and does not transform media or create hidden downstream behavior
Rejected: Auto-merge media into one combined preview | would hide workflow structure and violate the endpoint-only product model
Confidence: high

Vidu-style video models can load parameter schemas that change the Generate Video node height and trigger React Flow dimension updates. The fix keeps schema-driven resize notifications stable, skips no-op node height writes, and ignores duplicate React Flow node changes before they enter the workflow store.
It also preserves completed media outputs when a stopped or reloaded workflow still has transient loading/skipped state, so existing video results do not appear stuck after recovery.
Constraint: The crash was reported from a browser state where choosing Vidu hit React's maximum update depth in onNodesChange.
Rejected: Clear browser storage as the fix | it would hide persisted workflow loops without fixing the update path.
Rejected: Remove dynamic video handles | visible media/text inputs are product behavior and required for model-specific workflows.
Confidence: high
Scope-risk: moderate
Directive: Keep React Flow dimension and schema resize writes idempotent; new node resize paths should no-op when dimensions are already applied.

The accumulated fixes move the test build toward the current product shape: Popi models are the default provider surface, remote community workflow APIs are removed from the local template flow, media nodes expose accurate preview/preview-modal behavior, and Generate Video owns first-class duration, resolution, and sound defaults instead of burying those values in provider schemas.
The test suite was brought back in line with the product mode split: Popi provider mode is the default runtime, while multi-provider model search remains covered explicitly under multi mode.
Constraint: Product direction is canvas-owned workflow structure with Popi Models as the tested default provider path.
Rejected: Keep legacy community workflow API surface | user requested removing remote data paths and retaining local templates.
Rejected: Treat video duration/resolution/sound as hidden provider params | these are user-facing Generate Video controls.
Confidence: high
Scope-risk: broad
Directive: Do not reintroduce remote community template loading without a product decision on hosted templates and i18n ownership.

New users now land on Popi gateway defaults that match the tested production-style path: APIYI Nano Banana 2 for images, Doubao Seedance for video, and Doubao Seed 2.0 Lite for LLM chat/tool use. Settings and FTUX screens render these effective defaults instead of empty placeholders, while existing local node defaults keep taking precedence.
The same pass keeps provider-overload errors user-facing by formatting the model name that the node currently displays, so fallback and switched-model failures are easier to understand across media nodes.
Constraint: Popi mode should hide internal NewApiWG naming and default to models available through the Popi gateway.
Rejected: Persist default values into localStorage for every new user | would make future system default changes harder and could overwrite explicit user preferences.
Confidence: high
Scope-risk: moderate

Default provider mode now exposes only Popi Models while preserving the existing multi-provider implementation behind an explicit multi mode. The model browser, project settings, onboarding, node badges, and model API all share the same provider-mode decision so the test deployment matches the www.popi.art login-aligned direction.
This also includes the pending UI and i18n node-label changes already present in the tracked worktree so the committed state matches the verified build.
Constraint: Product entry must align with www.popi.art by exposing Popi Models instead of internal NewApiWG naming
Constraint: Test deployment should match the full tracked working tree that passed build
Rejected: Delete legacy provider code | multi-provider internals remain useful behind PROVIDER_MODE=multi

P0 regressions showed several workflow paths needed to stay visible and deterministic: language switching had a hardcoded composer label, Video Trim hid controls before media loaded, and media handoffs to LLM needed real canvas edges rather than implicit conversion. P1 fixes keep canvas-owned structure by adding explicit image/video LLM handles, audio composer validation, 3D output/file routing, and Chat proposal cards that require user apply before mutating nodes.
Constraint: User asked to stop new feature work and only repair P0/P1 product-fit gaps.
Rejected: Auto-convert image or video directly into text for LLM | hides workflow structure and violates the visible-node product model.
Rejected: Let Chat tool calls silently add or edit nodes | canvas structure must be previewed and explicitly applied.
Confidence: high
Scope-risk: moderate
Directive: Keep media transformations represented by visible handles, nodes, and edges; do not add silent Chat or media mutation paths without product review.

P0/P1 reports clustered around unavailable LLM defaults, video media connections, and missing controls on the generation surface. This routes the default NewApiWG LLM away from the unavailable Doubao channel, makes video a first-class schema and canvas connection type, carries request ids into node errors, and fills the composer, trim, audio, and 3D gaps without changing the canvas workflow model.
Constraint: NewApiWG Doubao channels are not reliably routed in the default gateway
Constraint: Video model schemas expose video fields that must not flow through image handles

The browser path helper briefly acted as a type predicate, which made existing non-browser path branches narrow to never under the production build. The callers now guard nullable paths explicitly while the helper stays a plain boolean check.

Browser-local projects were deriving a null generations path, so carousel entries that only retained an image id could not resolve media during previous/next navigation. Generated images are now written into the browser-selected generations folder, project metadata keeps that browserfs generations path, and the image node can read browserfs generation files directly before falling back to the server load endpoint.
Constraint: Browser-selected folders cannot be read through server API routes.
Rejected: Keep relying on inline image history only | saved or migrated workflows can contain id-only history entries.
Confidence: high
Scope-risk: moderate
Directive: Browser-local media paths must stay on the File System Access API path, not server /api/load-generation.

Browser-local projects cannot load node carousel history through the server-side generations API. Each new image history entry now keeps the generated data URL for immediate in-session switching, while server-backed projects can still fall back to loading by generation id. Browser-local generation paths also skip /api/save-generation because that endpoint can only write server filesystem paths.
Constraint: Project storage can be browser-local and therefore unavailable to server filesystem APIs.
Rejected: Force carousel switching through /api/load-generation | browserfs paths cannot be resolved by the server and cause switching failures.
Confidence: high
Scope-risk: narrow
Directive: Keep carousel history able to switch without server round-trips when images were generated in the current session.

This aligns image, video, and text defaults with the PopiArt NewApi gateway while keeping provider-specific escape hatches available. Chat now uses the OpenAI-compatible NewApiWG route so workflow editing and LLM generation share the same Doubao-first text default. The canvas composer and quick-add controls are tightened so visible actions map to real clickable behavior, while temporarily unused header actions stay hidden.
Constraint: Text/chat requests must prefer Doubao-Seed-2.0-lite through NewApiWG.
Constraint: Image and video defaults should prefer PopiArt NewApi gateway models when configured.
Rejected: Keep /api/chat on Gemini 3 Flash | conflicts with the requested NewApiWG text/chat default.
Rejected: Hand-roll AI SDK chat streaming | would risk tool-call and UI stream compatibility.

Provider video URLs can expire before users finish composing, and the bottom composer was too visually dominant for canvas work. This change keeps remote videos playable while background-localizing them, teaches video previews to use the media proxy, makes audio nodes first-class in the composer and executor, and adds a compact composer state for canvas visibility.
Constraint: Provider media URLs may be remote, signed, or CORS-restricted during playback and thumbnail extraction
Constraint: Audio generation nodes need to work from their internal prompt as well as connected text
Rejected: Store only provider URLs | remote URLs can expire and break later playback
Rejected: Treat audio nodes as unsupported composer nodes | it falls back to the image model and corrupts user intent

The bottom composer now edits and reruns the current generation node while canvas-visible actions own downstream node creation. NewApiWG media normalization, video frame extraction, and node quick-add keep generated media flows explicit and connected rather than hidden behind the prompt box.
Constraint: Composer must not call providers directly or create hidden downstream branches when a node is selected
Constraint: NewApiWG video families use inconsistent media schemas, so common media aliases are normalized in the provider adapter
Rejected: Let the bottom composer create next-step nodes from selected outputs | hides graph mutation and conflicts with the PRD source-of-truth rules

Server-side native folder pickers cannot select a Windows user's local directory when the app is deployed remotely. This adds a browser File System Access path for supported browsers so the user can choose a local folder, create the project subfolder, and save the workflow JSON directly from the client.
Constraint: File System Access handles are browser-only and cannot be passed to server filesystem APIs
Constraint: External media folder storage still depends on server filesystem endpoints, so browser-local projects keep media embedded or remote in the workflow JSON
Rejected: Make /api/browse-directory choose the user's Windows folder | that endpoint runs on the server, not in the browser

Gemini image models (nano-banana, nano-banana-pro, nano-banana-2) were
not showing parameters when set as fallback models. Three root causes:
1. Schema API returned empty for Gemini image models — added
getGeminiImageSchema() with aspect ratio, resolution, and search
grounding parameters per model
2. ModelParameters had an early-return guard skipping all non-Veo Gemini
models — removed to make the component provider-agnostic
3. nanoBananaExecutor ignored parametersOverride for Gemini-specific
fields (aspectRatio, resolution, useGoogleSearch, useImageSearch) —
now reads from override when available
