-# Build UI Service Provider + Lit Custom Elements
-
-**Date**: 14 March 2026
-**Module**: `forge.lthn.ai/core/go-build`
-**Pattern**: Follows `go-scm/pkg/api/` provider + `go-scm/ui/` Lit elements
-
-## Overview
-
-Add a service provider (`BuildProvider`) that exposes the existing build, release, and SDK subsystems as REST endpoints, plus a set of Lit custom elements for GUI display within the Core IDE.
-
-The provider wraps existing functions — no business logic is reimplemented.
-
-## Architecture

-## REST Endpoints
-
-All under `/api/v1/build`:
-
-| Method | Path                | Handler          | Wraps                              |
-|--------|---------------------|------------------|------------------------------------|
-| GET    | /config             | getConfig        | `build.LoadConfig(io.Local, cwd)`  |
-| GET    | /discover           | discoverProject  | `build.Discover(io.Local, cwd)`    |
-| POST   | /build              | triggerBuild     | Full build pipeline                |
-| GET    | /artifacts          | listArtifacts    | Scan `dist/` directory             |
-| GET    | /release/version    | getVersion       | `release.DetermineVersion(cwd)`    |
-| GET    | /release/changelog  | getChangelog     | `release.Generate(cwd, "", "")`    |
-| POST   | /release            | triggerRelease   | `release.Run()` or `Publish()`     |
-| GET    | /sdk/diff           | getSdkDiff       | `sdk.Diff(base, revision)`         |
-| POST   | /sdk/generate       | generateSdk      | `sdk.SDK.Generate(ctx)`            |

-## WS Channels
-
-- `build.started` — Build commenced (includes project type, targets)
-- `build.complete` — Build finished (includes artifact list)
-- `build.failed` — Build error (includes error message)
-- `release.started` — Release pipeline started
-- `release.complete` — Release published
-- `sdk.generated` — SDK generation complete
-
-## Custom Elements
-
-### `<core-build-panel>` (build-panel.ts)
-Top-level tabbed container with tabs: Config, Build, Release, SDK.
-Follows HLCRF layout from go-scm.
-
-### `<core-build-config>` (build-config.ts)
-- Displays `.core/build.yaml` fields (project name, binary, targets, flags, signing)
-- Shows detected project type from discovery
-- Read-only display of current configuration
-
-### `<core-build-artifacts>` (build-artifacts.ts)
-- Lists files in `dist/` with size, checksum status
-- "Build" button with confirmation dialogue (POST /build is destructive)
-- Real-time progress via WS events
-
-### `<core-build-release>` (build-release.ts)
-- Current version from git tags
-- Changelog preview (rendered markdown)
-- Publisher targets from `.core/release.yaml`
-- "Release" button with confirmation dialogue
-
-### `<core-build-sdk>` (build-sdk.ts)
-- OpenAPI diff results (breaking/non-breaking changes)
-- SDK generation controls (language selection)
-- Generation status
-
-## Dependencies Added to go.mod
-
-```
-forge.lthn.ai/core/api v0.1.0
-forge.lthn.ai/core/go-ws v0.1.0
-github.com/gin-gonic/gin v1.11.0
-```
-
-## Safety Considerations
-
-- POST /build and POST /release are destructive operations
-- UI elements include confirmation dialogues before triggering
-- Provider accepts a `projectDir` parameter (defaults to CWD)
-- Build/release operations run synchronously; WS events provide progress
-
-## Implementation Tasks
-
-1. Create `pkg/api/provider.go` — BuildProvider struct + all handlers
-2. Create `pkg/api/provider_test.go` — Identity + config/discover tests
-3. Create `pkg/api/embed.go` — //go:embed directive
-4. Create `ui/` directory with full Lit element suite
-5. Update `go.mod` — add api, go-ws, gin dependencies
-6. Build UI (`cd ui && npm install && npm run build`)
-7. Verify Go compilation (`go build ./...`)
