-## Existing Workflows
-
-### 1. build.yml
-- **Trigger**: Push to `main`
-- **Action**: Builds picoclaw using `make build-all`
-- **Platform**: Ubuntu latest
-
-### 2. release.yml
-- **Trigger**: Manual workflow dispatch
-- **Actions**:
-  - Creates git tag
-  - Runs GoReleaser to build for all platforms
-  - Uploads to GitHub Releases
-  - Optionally uploads to TOS
-- **Platforms**: Linux, Windows, Darwin, FreeBSD (amd64, arm64, riscv64, loong64, arm)
-- **Docker**: Multi-platform builds to GHCR and DockerHub
-
-### 3. pr.yml
-- **Trigger**: Pull requests
-- **Action**: PR validation (details not visible in current session)
-
-### 4. upload-tos.yml
-- **Trigger**: Called from release workflow
-- **Action**: Uploads artifacts to Volcengine TOS
-
-## Build System
-
-### Makefile Targets
-| Target | Description |
-|--------|-------------|
-| `build` | Build for current platform |
-| `build-all` | Build for all platforms (8 variants) |
-| `build-whatsapp-native` | Build with WhatsApp native support |
-| `build-linux-arm` | Build for Linux ARMv7 |
-| `build-linux-arm64` | Build for Linux ARM64 |
-| `build-pi-zero` | Build for Raspberry Pi Zero 2 W |
-| `install` | Install to `~/.local/bin` |
-| `test` | Run tests |
-| `lint` | Run golangci-lint |
-| `docker-build` | Build minimal Docker image (Alpine) |
-| `docker-build-full` | Build full Docker image (Node.js 24) |
-

-
-**Target Platforms:**
-- OS: Linux, Windows, Darwin, FreeBSD
-- Arch: amd64, arm64, riscv64, loong64, arm (v6, v7)
-
-**Docker Images:**
-- `ghcr.io/<owner>/picoclaw`
-- `docker.io/<repository>`
-- Platforms: linux/amd64, linux/arm64, linux/riscv64

-## Nightly Build Requirements
-
-### Goals
-1. Build daily snapshots of the `main` branch
-2. Upload artifacts to GitHub Releases (as pre-release)
-3. Optionally build and push Docker images
-4. Keep limited number of nightly builds (cleanup old ones)
-
-### Design Decisions
-
-| Decision | Rationale |
-|----------|-----------|
-| **Cron Schedule**: `0 2 * * *` (2 AM UTC) | Off-peak hours, allows testing during business day |
-| **Release Type**: Pre-release | Clearly distinguishes from stable releases |
-| **Tag Format**: `nightly-YYYYMMDD` | Easy to identify and sort by date |
-| **Artifact Retention**: 30 days | Balance between availability and storage |
-| **Docker Tags**: `nightly`, `nightly-YYYYMMDD` | Allow both latest and pinned versions |
-

-## Notes
-
-1. **Security**: No secrets required for basic nightly builds
-2. **Storage**: GitHub provides 2GB free storage; implement cleanup if needed
-3. **Testing**: Nightly builds serve as canary builds for testing
-4. **Docker**: Can optionally push `nightly` Docker tags
-5. **Notifications**: Could add Slack/discord notifications on failure
