# Progress Log

## Session: 2026-07-10

### Phase 1: Architecture Discovery
- **Status:** in_progress
- Read repository instructions and the applicable Go, frontend, planning, and browser verification skills.
- Captured the missing backend ownership, project binding, selector, and chat-context requirements.
- Confirmed the existing go-zero API, SQLC/PostgreSQL, memory-store, and code-generation toolchain.
- Located the project domain/repository and established the project object as the server-side Brand Kit context boundary for chat and generation.
- Traced Agent Chat through planning, research, conversation, and asynchronous generation; identified one project-hydration point plus shared prompt builders for complete coverage.
- Added the Home composer Brand Kit picker and empty create action to the implementation scope.
- Mapped the Home composer action row and frontend project hydration paths for `brandKitId` integration.
- Re-read the active plan after session recovery and confirmed the existing frontend edits are limited to the Brand Kit feature surface.
- Loaded the project go-zero workflow plus the applicable planning, Go, and frontend implementation guidance.
- Completed architecture discovery, including authentication enforcement, SQLC persistence, async job reloads, direct image prompts, and frontend project hydration.
- Chose a versioned JSON document API with server-side schema validation and prompt compilation; project responses expose only `brandKitId`, never compiled context.
- Added and validated the API-first contract for Brand Kit list/upsert/delete, project binding, optional project-creation selection, and project response hydration.
- Generated go-zero handlers, logic shells, routes, and types through the local `mcp-zero` stdio server.
- Added SQLC schema and queries for user-owned versioned Brand Kits and optional project bindings, then regenerated SQLC code.
- Implemented memory/PostgreSQL stores, document validation, single-default enforcement, server-side context compilation, project binding cleanup, and API logic.
- Hydrated the active Brand Kit for synchronous chat, asynchronous create/follow-up jobs, conversations, planner memory, creative prompts, and direct/fallback image prompts.
- Added focused ownership/default/binding/context-injection tests.
- Replaced browser-local Brand Kit persistence with authenticated APIs, including a one-time per-user migration.
- Added reusable Brand Kit selectors to the Home composer and canvas title bar; project creation and binding now send only the selected ID.
- Added server-side Brand Kit asset resolution so uploaded logos, covers, and references reach image generation after user references.
- Added Brand Kit API documentation and ownership/default/binding semantics to the server docs.

## Test Results
| Test | Result | Status |

| Targeted Go tests: application, PostgreSQL/memory repositories, logic, service context, error mapping, and prompt agents | all pass | pass |
| `go test ./...` | all packages pass | pass |
| `go build ./...` | build succeeds | pass |
| `npx tsc -b` | typecheck succeeds | pass |
| `npm run build` | Next.js and Vite production builds succeed; existing large-chunk warning only | pass |
