## Summary
- register the Go `DuckDuckGo` canvas component and restore its dynamic
input form metadata
- align the Go component input/output surface with the current canvas
usage for `query`, `channel`, and `top_n`
- fix DuckDuckGo news search in Go by fetching the required `vqd` token
before calling `news.js`, and add targeted regression tests
## Testing
Passed:
- `bash build.sh --test ./internal/agent/tool/... -run 'DuckDuckGo'`
- `bash build.sh --test ./internal/agent/component/... -run
'DuckDuckGo|TestVerifyRegistration_P1'`
- `bash build.sh --test ./internal/agent/component/... -run
'DuckDuckGo'`
Not run:
- frontend tests
- frontend build
- full Go test suite

### Summary
- Implemented googleComponent wrapper to bridge the canvas component
contract with Eino's SerpApi-backed GoogleTool.
- Added parameter alias mapping (query to q, max_results to num) and
content formatting logic to match Python search result representation.
- Registered the "Google" component and the "google" tool factory in the
Go agent runtime to support web search nodes.

### Summary
- TavilySearch now stores api_key from component params and injects it
into tool calls when runtime inputs omit it.
- TavilyExtract and BGPT now follow the same stored api_key behavior.
- Canvas decoding now recovers api_key from graph.nodes[].data.form when
components[].obj.params.api_key is empty, matching frontend payload
behavior without changing frontend data.
- Added regression tests for graph form key recovery and stored key
injection / caller key precedence.
Tests: build.sh --test ./internal/agent/component ./internal/service —
all pass.

## Summary
Adds the missing input form metadata for the Go BGPT canvas component.
## Root Cause
The standalone BGPT component was registered in Go, but it did not
implement GetInputForm(). During component trial run, the backend asks
the component for its input_form. Since BGPT had none, the API returned:
component has no input_form: BGPT:<node_id>
Python BGPT already exposes the query input form, so the Go component
needed the same contract.
## Change
Added GetInputForm() to the Go BGPT component with a single query line
input.
Added test coverage to ensure BGPT exposes the input form.
## Validation
Backend:
bash build.sh --test -run TestBGPT ./internal/agent/component

## Summary
Debugging YahooFinance component in agent canvas returns "unknown
component" and "no input_form".
YahooFinance was only registered as an eino tool, not as a runtime
component. The component factory only searches the runtime registry.
- `universe_a_wrappers.go`: add `yahooFinanceComponent` wrapper
delegating to `agenttool.YahooFinanceTool` with `GetInputForm()`
- `fixture_stubs.go`: register `"YahooFinance"` component
## TEST
`go build` and `go test ./internal/agent/component/...` all pass.
Replaces the Python agent canvas runtime with a Go implementation that
runs inside `cmd/server_main`.
The canvas compiles into an eino Workflow that pauses on wait-for-user
via native Interrupt/Resume (no sentinel flag) and resumes from a
Redis-backed CheckPointStore.
All 21 Python agent components and ~35 tools are ported with functional
parity.
Sandbox providers now read their JSON config from the admin-panel
system_settings table with env fallback.
234 files / +35,413 / -6,111. All Go files are gofmt-clean (CI gate
added); drops the v2 DSL E2E step and the gap-analysis plan (both
redundant after the port ships).
