+
+## CONVENTIONS
+- **Go**: Standard layout (`main.go` in root, `internal/`, `api/`)
+- **Vue 3**: Composition API + `<script setup lang="ts">` throughout
+- **State management**: Pinia stores in `src/stores/`
+- **API client**: Axios-based services in `src/api/` + base `src/services/`
+- **Styling**: TailwindCSS v4 (no PostCSS — `@tailwindcss/vite` plugin)
+- **DB**: GORM ORM, PostgreSQL, AutoMigrate in dev / `-migrate-prod` in prod
+- **Naming**: `UPPER_SNAKE_CASE` env vars, `camelCase` Go vars, `PascalCase` exported Go
+- **Auth**: JWT, admin-only enforced by middleware pattern
+- **Build tags**: `//go:build dev` for AutoMigrate
+- **Capabilities**: Server containers need `NET_ADMIN` + `NET_RAW`
+- **Ports**: API 8080, Dashboard 80 (Nginx), Postgres 5432, Redis 6379
+
+## ANTI-PATTERNS (THIS PROJECT)
+- **NEVER** `nft flush table` — only atomic add/remove
+- **NEVER** log plaintext or encryption keys
+- **NEVER** reopen completed phases/commits — fix forward only
+- **NEVER** rebuild `shared/crypto/encryptor.go` — copy identical file
+- **NEVER** commit build artifacts (binaries, `dist/`)
+- **NEVER** force push
+- **NEVER** create cross-phase workarounds
+
+## UNIQUE STYLES
+- **Zero-Attack Surface**: `/auth/register` locked; admin via `-create-admin` CLI only
+- **Stealth Agent**: No `/etc/wireguard/` — config in memory only
+- **Duplicate crypto**: `encryptor.go` copy-pasted in server-core + device-agent (known debt, do not deduplicate)
+- **nftables default Accept**: Contradicts Zero-Trust "Default DROP" — intentional gap
+
+## COMMANDS
+```bash
+make up              # Start all services
+make down            # Stop all services
+make dev             # Start with hot-reload (air)
+make logs            # Tail all logs
+make migrate         # Run DB migration (requires local Go)
+make reset-db        # Nuke PG volume + recreate + migrate
+
+cd apps/server-core && go run -tags dev .
+cd apps/dashboard-ui && npm run dev
+cd apps/device-agent && go run .
+
+go run -tags dev ./apps/server-core -create-admin -user admin -pass "..."
+```
+
+## NOTES
+- Submodules → private Gitea (`git.datadunia.com`); CI via Gitea Actions per submodule
+- Go versions diverge: server-core `1.25.7`, device-agent `1.25.1`
+- No root linter configs (`.golangci.yml`, `.eslintrc`, `.editorconfig`)
+- Shell scripts use deprecated `docker-compose` v1, Makefile uses `docker compose` v2
+- Root has stale artifacts: `connect_remote.txt`, `temp_section*.txt`
+- `package.json` name is `"temp-ui"` (stale scaffold remnant)

+- **Stack**: Go 1.25.7, Gin 1.12, GORM 1.31 (PostgreSQL), JWT v5, go-redis 9.x, google/nftables 0.3, wgctrl
+- **DB**: GORM AutoMigrate in dev (`-tags dev`); `-migrate-prod` for production
+- **Auth**: JWT middleware in `api/` — repeated admin-only checks (not centralized)
+- **API style**: Gin `c.JSON` responses, status codes, error message strings
+- **nftables**: Default Accept policy (`nftables_linux.go:35`) — known doc gap
+
+## ANTI-PATTERNS (THIS PROJECT)
+- **NEVER** `nft flush table` — destroys all peer isolation
+- **NEVER** log plaintext or encryption keys
+- **Admin-only authorization** is copy-pasted across 7+ handler files — refactoring opportunity
+
+## COMMANDS
+```bash
+go run -tags dev .                          # Dev server

+go run -tags dev . -create-admin -user admin -pass "..."
+go test ./... -tags dev -cover              # Run all tests
+```
+
+## NOTES
+- API runs on port 8080 (configurable via `PORT`/`API_PORT`)
+- Docker needs `NET_ADMIN` + `NET_RAW` capabilities
+- Tests exist for auth, devices, provisioning, rules, share

+# Node Config Lifecycle Hooks & Documentation Infrastructure
+
+## TL;DR
+> **Quick Summary**: Complete the missing WireGuard lifecycle hooks (`PreDown`, `PostUp`) across the backend API and frontend UI. Simultaneously, establish standard documentation infrastructure using Swagger for the API and VitePress for static HTML documentation.
+>
+> **Deliverables**:
+> - Backend DB Model & API updated with `PreDown` and `PostUp`
+> - Dashboard UI updated with two new textareas for the hooks
+> - Swagger UI integrated at `server-core` (`/swagger/index.html`)
+> - Static HTML docs (VitePress) initialized in `apps/docs` with standard WireGuard guide structures
+>
+> **Estimated Effort**: Medium
+> **Parallel Execution**: YES (Frontend, Backend, and Docs can be built in parallel waves)
+> **Critical Path**: Backend API update -> Frontend UI update -> Swagger setup -> VitePress setup
+
+---
+
+## Context
+### Original Request
+The user noted that the Node (WgServer) configuration currently lacks inputs for `PreDown` and `PostUp` (only `PreUp` and `PostDown` were present). Additionally, the user requested a plan for establishing HTML documentation (referencing wgdashboard documentation structure) and Swagger API documentation.
+
+### Discussion & Findings
+- **Backend**: Found `PreUp` and `PostDown` in `apps/server-core/internal/models/models.go` and `apps/server-core/api/servers.go`.
+- **Frontend**: Found `PreUp` and `PostDown` in `apps/dashboard-ui/src/views/Servers.vue` and `apps/dashboard-ui/src/api/servers.ts`.
+- **Docs**: Neither `swag` nor `apps/docs` currently exists in the project.
+
+### Self-Review (Metis Simulation)
+- **Guardrail**: String fields in GORM should use `gorm:"type:text"` to accommodate long bash scripts.
+- **Guardrail**: Swagger requires running `swag init` to generate `docs/docs.go`, which must be anonymously imported in `main.go`.
+- **Guardrail**: VitePress should be isolated in `apps/docs` as an independent NPM project to prevent polluting `dashboard-ui`.
+
+---
+
+## Work Objectives
+
+### Core Objective
+Achieve full parity with WireGuard's standard lifecycle hooks in the database and UI, and lay down the foundation for professional developer and user documentation.
+
+### Must Have
+- `PreDown` and `PostUp` fields in `WgServer` model.
+- Swagger annotation for at least the `Servers` endpoints to serve as a template.
+- VitePress sidebar containing the requested links: Access Remote Server, Add WireGuard Config, Peers, Sign In, Email Service, WebHooks.
+
+### Must NOT Have
+- Do NOT merge VitePress into `apps/dashboard-ui/package.json`. It must be its own independent app in `apps/docs`.
+

+```
+
+---
+
+## TODOs
+
+- [x] 1. Update Backend Schema & API (`PreDown`, `PostUp`)
+
+  **What to do**:
+  - Edit `apps/server-core/internal/models/models.go`: Add `PreDown` and `PostUp` (type string, `gorm:"type:text"`) to the `WgServer` struct.
+  - Edit `apps/server-core/api/servers.go`:
+    - Add `PreDown` and `PostUp` to `CreateServerRequest` and `UpdateServerRequest`.
+    - Map these fields when creating/updating the model inside `CreateServer` and `UpdateServer` handlers.
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick`
+  - **Skills**: `[]`
+
+  **Parallelization**: Wave 1
+
+  **Acceptance Criteria**:
+  - [ ] `grep -q "PreDown" apps/server-core/internal/models/models.go` passes.
+  - [ ] `grep -q "PostUp" apps/server-core/internal/models/models.go` passes.
+
+  **QA Scenarios**:
+  ```text
+  Scenario: API accepts PreDown and PostUp
+    Tool: Bash (curl)
+    Preconditions: Server is running
+    Steps:
+      1. Send a POST or PUT request to `/api/v1/servers` with `pre_down` and `post_up` in JSON payload.
+    Expected Result: Payload is accepted and saved without error.
+    Evidence: .sisyphus/evidence/task-1-api-update.json
+  ```
+
+---
+
+- [x] 2. Initialize VitePress HTML Docs
+
+  **What to do**:
+  - Create directory `apps/docs`.
+  - Initialize a standard `package.json` for VitePress.
+  - Create `.vitepress/config.mts` with a sidebar structure matching the requested references:
+    - Guides: Sign In, Access Remote Server, Add WireGuard Configuration, Add WireGuard Configuration Peers, Email Service, WebHooks.
+  - Create markdown stubs for all the above pages inside `apps/docs/guides/`.
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick`
+  - **Skills**: `[]`
+
+  **Parallelization**: Wave 1
+
+  **Acceptance Criteria**:
+  - [ ] `apps/docs/package.json` exists with `vitepress` dependency.
+  - [ ] `apps/docs/.vitepress/config.mts` configures the sidebar properly.
+  - [ ] Markdown stubs exist for all guides.
+
+  **QA Scenarios**:
+  ```text
+  Scenario: VitePress builds successfully
+    Tool: Bash
+    Preconditions: npm is installed
+    Steps:
+      1. cd apps/docs && npm install && npm run docs:build
+    Expected Result: Build completes successfully producing static HTML in .vitepress/dist.
+    Evidence: .sisyphus/evidence/task-2-vitepress-build.txt
+  ```
+
+---
+
+- [x] 3. Update Frontend Dashboard UI (`PreDown`, `PostUp`)
+
+  **What to do**:
+  - Edit `apps/dashboard-ui/src/api/servers.ts`: Add `PreDown?: string` and `PostUp?: string` to the node interface.
+  - Edit `apps/dashboard-ui/src/views/Servers.vue`:
+    - Add two new textarea fields for `PostUp` and `PreDown` in the Add/Edit Node modal.
+    - Order should logically be: `PreUp`, `PostUp`, `PreDown`, `PostDown`.
+    - Ensure reactivity maps these inputs to the payload correctly.
+
+  **Recommended Agent Profile**:
+  - **Category**: `visual-engineering`
+  - **Skills**: `["vue-ui-futuristic/tailwind-futuristic"]`
+
+  **Parallelization**: Wave 2 (Depends on Task 1)
+
+  **Acceptance Criteria**:
+  - [ ] Types updated.
+  - [ ] Form UI contains 4 total textarea boxes for the WireGuard hooks.
+
+  **QA Scenarios**:
+  ```text
+  Scenario: UI renders new fields
+    Tool: Playwright
+    Preconditions: UI is running
+    Steps:
+      1. Navigate to Nodes page, click Register Node.
+    Expected Result: PreDown and PostUp textareas are visible.
+    Evidence: .sisyphus/evidence/task-3-ui-fields.png

+
+- [x] 4. Setup Swagger API Documentation
+
+  **What to do**:
+  - In `apps/server-core`, add `github.com/swaggo/swag/cmd/swag` and `github.com/swaggo/gin-swagger` via `go get`.
+  - Add standard `@title`, `@version`, `@description` in `main.go`.
+  - Add Swagger annotations (`@Summary`, `@Tags`, `@Accept`, `@Produce`, `@Success`) to the handlers in `api/servers.go`.
+  - Mount `/swagger/*any` using `ginSwagger.WrapHandler(swaggerFiles.Handler)` in the Gin router.
+  - Create a Makefile target `make swagger` inside `apps/server-core/Makefile` (or update existing) that runs `swag init`. Run it once so the `docs/` folder is generated.
+
+  **Recommended Agent Profile**:
+  - **Category**: `deep`
+  - **Skills**: `[]`
+
+  **Parallelization**: Wave 2
+
+  **Acceptance Criteria**:
+  - [ ] `go.mod` contains swaggo dependencies.
+  - [ ] `/swagger/index.html` serves the API documentation.
+  - [ ] `apps/server-core/docs/swagger.json` exists.
+
+  **QA Scenarios**:
+  ```text

+# Server Core Multi-stage Docker Build
+
+## TL;DR
+
+> **Quick Summary**: Convert `apps/server-core/Dockerfile` from single-stage (requires pre-built binary on host) to multi-stage (builds from source inside Docker). Also clean up orphan binaries, update `.gitignore`, and untrack the accidentally-tracked `server-core-linux` binary from the submodule.
+>
+> **Deliverables**:
+> - Multi-stage `apps/server-core/Dockerfile` (builder + production stages)
+> - `.dockerignore` in `apps/server-core/` to exclude build artifacts
+> - Updated `apps/server-core/.gitignore` (`server-core` → `server-core*`)
+> - `server-core-linux` removed from git tracking
+> - 3 orphan binary files deleted from disk
+> - Submodule commit + parent pointer update
+>
+> **Estimated Effort**: Short
+> **Parallel Execution**: NO — sequential (submodule operations must order correctly)
+> **Critical Path**: Update .gitignore → git rm → commit submodule → delete binaries → rewrite Dockerfile → add .dockerignore → update parent pointer → verify
+
+---
+
+## Context
+
+### Original Request
+The user noticed that `apps/server-core/` has compiled binaries (`server-core`, `server-core-linux`, `bin/server-core`) that are build artifacts and shouldn't be in the repo. After discussion, agreed on multi-stage Dockerfile approach so binaries never need to exist on the host.
+
+### Interview Summary
+**Key Discussions**:
+- `apps/server-core` is a git submodule (as are `apps/dashboard-ui` and `apps/device-agent`)
+- `docker-compose.dev.yml` already references `target: builder` — the dev compose was designed expecting multi-stage, but Dockerfile was never updated
+- Dashboard UI already uses proper multi-stage pattern (Node build → Nginx serve)
+- User wants buildable from anywhere: root via `docker compose up`, or directly from submodule via `docker build`
+
+### Metis Review
+**Identified Gaps** (addressed):
+- **`server-core-linux` is git-tracked**: Requires `git rm --cached` + `.gitignore` update in the submodule (not just root `.gitignore`)
+- **`WORKDIR /src` breaks dev compose**: Builder stage must use `WORKDIR /app` because dev compose volume-mounts source at `/app` and runs `air` there
+- **No layer caching**: Without `COPY go.mod go.sum → go mod download`, every build re-downloads all ~70 dependencies
+- **No `.dockerignore`**: 133MB orphan binaries inflate build context to Docker daemon
+- **Submodule workflow**: Changes must be committed to submodule remote first, then parent submodule pointer updated
+
+---
+
+## Work Objectives
+
+### Core Objective
+Eliminate need for pre-built Go binaries on the host by converting the Dockerfile to multi-stage build, while keeping all existing behavior (runtime deps, ports, CMD) identical.
+
+### Concrete Deliverables
+- `apps/server-core/Dockerfile` — rewritten to multi-stage
+- `apps/server-core/.dockerignore` — new file
+- `apps/server-core/.gitignore` — updated pattern
+- Git submodule commit + parent repo pointer update
+
+### Definition of Done
+- [x] `docker build -f Dockerfile .` succeeds from `apps/server-core/` (needs Docker host)
+- [x] `docker compose build server-core` succeeds from project root (needs Docker host)
+- [x] `docker run --rm <image> sh -c "test -f /app/server-core"` confirms binary exists (needs Docker host)
+- [x] `docker run --rm <image> sh -c "nft --version && wg --version && ip --version"` confirms runtime deps work (needs Docker host)
+- [x] `git -C apps/server-core ls-files server-core-linux` returns empty (untracked)
+- [x] No binary artifacts on disk in `apps/server-core/` root or `bin/`
+
+### Must Have
+- Multi-stage Dockerfile that builds from source inside Docker — no host binary required
+- Builder stage uses `WORKDIR /app` (compatible with dev compose mount)
+- Final stage identical runtime to current: same `apk add` packages, same EXPOSE, same CMD
+- `CGO_ENABLED=0` in `go build` for Alpine compatibility
+- Layer caching: `COPY go.mod go.sum ./` → `RUN go mod download` → `COPY . .` → `RUN go build`
+- `server-core*` pattern in submodule `.gitignore` (not just `server-core`)
+- `.dockerignore` to exclude binaries, `.git/`, `docs/`, `README.md` from build context
+
+### Must NOT Have (Guardrails)
+- No changes to Go source code (main.go, internal/, etc.)
+- No changes to `docker-compose.yml` or `docker-compose.dev.yml`
+- No changes to `Makefile`
+- No BuildKit cache mounts (keeps portability with older Docker / CI)
+- No linting, multi-arch, health checks, or other "nice-to-have" additions
+- No `WORKDIR /src` — would silently break dev compose
+
+---
+
+## Verification Strategy
+
+> **ZERO HUMAN INTERVENTION** — ALL verification is agent-executed.
+
+### Test Decision
+- **Infrastructure exists**: YES (Docker)
+- **Automated tests**: NONE — this is Dockerfile + config changes, not application code
+- **Agent-Executed QA**: Shell commands (docker build, docker run, git, file system checks)
+
+### QA Policy
+Every task includes agent-executed QA scenarios. Evidence saved to `.sisyphus/evidence/task-{N}/`.
+
+---
+
+## Execution Strategy
+
+### Sequential Execution (submodule workflow requires ordering)
+
+```
+Task 1: Update .gitignore pattern in submodule
+Task 2: git rm --cached server-core-linux (untrack binary)
+Task 3: Commit submodule changes (Dockerfile + .gitignore + binary removal)
+Task 4: Delete orphan binaries from disk
+Task 5: Write .dockerignore for submodule
+Task 6: Rewrite Dockerfile to multi-stage
+Task 7: Commit submodule remaining changes
+Task 8: Update parent repo submodule pointer
+Task 9: Verify builds
+```
+
+Tasks that can be parallelized: T4 + T5 + T6 (all file-level, no git deps between them once T3 is committed), T9 stand-alone.
+
+### Optimized Plan
+
+```
+Wave 1 (Sequential — git operations):
+├── T1: Update .gitignore (server-core → server-core*)
+├── T2: git rm --cached server-core-linux
+└── T3: Commit submodule
+
+Wave 2 (Parallel — file operations, T3 must complete first):
+├── T4: Delete orphan binaries from disk
+├── T5: Write .dockerignore
+└── T6: Rewrite Dockerfile multi-stage
+
+Wave 3 (Sequential — commit + verify):
+├── T7: Commit submodule remaining changes
+├── T8: Update parent submodule pointer
+└── T9: Verify builds

+
+- [x] 3. Commit submodule changes (gitignore + untrack)

+
+- [x] 7. Commit submodule remaining changes (Dockerfile + .dockerignore + binary deletions)
+
+- [x] 8. Update parent repo submodule pointer
+
+  **What to do**:
+  - Read `apps/server-core/.gitignore`
+  - Change line `server-core` to `server-core*` — this catches both `server-core` and `server-core-linux`
+
+  **Must NOT do**:
+  - Do NOT touch the root `.gitignore` — submodule has its own gitignore and submodule git ignores root gitignore
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick` — single-line change in one file
+  - **Skills**: none needed
+
+  **Parallelization**:
+  - **Can Run In Parallel**: NO (sequential — must be first)
+  - **Parallel Group**: Wave 1
+  - **Blocks**: Tasks 2, 3
+  - **Blocked By**: None
+
+  **References**:
+  - `apps/server-core/.gitignore:5` — Line to change: `server-core` → `server-core*`

+- [x] 2. Untrack `server-core-linux` from submodule git
+
+  **What to do**:
+  - Run: `git -C apps/server-core rm --cached server-core-linux`
+
+  **Must NOT do**:
+  - Do NOT physically delete the file yet (that's Task 4)
+  - Do NOT use `git rm` without `--cached` — that would also delete the file now
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick` — single git command
+  - **Skills**: none needed
+
+  **Parallelization**:
+  - **Can Run In Parallel**: NO (depends on T1)

+  - [ ] `git -C apps/server-core status --short` shows `server-core-linux` as untracked (not staged/deleted)
+
+  **QA Scenarios**:
+  ```
+  Scenario: Binary removed from git tracking
+    Tool: Bash (git)
+    Preconditions: Task 1 completed
+    Steps:
+      1. git -C apps/server-core ls-files --cached server-core-linux

+  ```
+
+  **Commit**: NO (batched with T3)
+

+
+- [x] 3. Commit submodule changes (gitignore + untrack binary)
+
+  **What to do**:
+  - Stage: `git -C apps/server-core add .gitignore`
+  - Stage: `git -C apps/server-core add server-core-linux` (the `--cached` removal shows as deletion when staged)
+  - Commit: `git -C apps/server-core commit -m "chore: ignore compiled binaries and remove tracked server-core-linux"`
+  - Push: if remote is accessible
+
+  **Must NOT do**:
+  - Do NOT commit the Dockerfile yet (that's Task 7 after rewriting)
+  - Do NOT force push
+
+  **Recommended Agent Profile**:
+  - **Skill**: `/git-master`
+  - **Category**: `quick`
+
+  **Parallelization**:

+
+  **QA Scenarios**:

+
+- [x] 4. Delete orphan binary files from disk
+
+  **What to do**:
+  - Delete these 3 files:

+    - `apps/server-core/server-core-linux` (44.7 MB)
+    - `apps/server-core/bin/server-core` (44.2 MB)
+  - Also remove `apps/server-core/bin/` if empty after deletion
+
+  **Must NOT do**:
+  - Do NOT delete anything in `apps/server-core/bin/` other than the binary (but `bin/` should only contain the binary)
+  - Do NOT delete any `.go` source files
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick` — simple file deletions
+  - **Skills**: none needed
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T5, T6)
+  - **Parallel Group**: Wave 2
+  - **Blocks**: Tasks 7, 9
+  - **Blocked By**: Task 3 (submodule committed)

+  **Acceptance Criteria**:
+  - [ ] `test ! -f apps/server-core/server-core` (file does not exist)
+  - [ ] `test ! -f apps/server-core/server-core-linux` (file does not exist)
+  - [ ] `test ! -f apps/server-core/bin/server-core` (file does not exist)

+
+  **QA Scenarios**:

+
+- [x] 5. Write `.dockerignore` for server-core submodule
+
+  **What to do**:
+  - Create `apps/server-core/.dockerignore` with content:
+    ```
+    .git/
+    .gitignore
+    .gitea/
+    .env
+    .env.*
+    !.env.example
+    docs/
+    README.md
+    bin/
+    server-core
+    server-core-linux
+    ```
+
+  **Must NOT do**:
+  - Do NOT include Go source files (they need to be in build context)
+  - Do NOT include `.dockerignore` itself (would exclude itself — harmless but pointless)
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick` — single new file
+  - **Skills**: none needed
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T4, T6)
+  - **Parallel Group**: Wave 2
+  - **Blocks**: Tasks 7, 9
+  - **Blocked By**: Task 3
+
+  **References**:
+  - None needed — standard `.dockerignore` for Go projects
+
+  **Acceptance Criteria**:
+  - [ ] `apps/server-core/.dockerignore` exists
+  - [ ] Contains `.git/`, `docs/`, `README.md`, `bin/`, `server-core*`, `.env.*`
+  - [ ] Does NOT contain `*.go` or `go.mod` or `go.sum`
+
+  **QA Scenarios**:
+  ```
+  Scenario: Dockerignore exists with correct entries
+    Tool: Bash (cat + grep)
+    Preconditions: Task 3 completed

+  ```
+
+  **Commit**: NO (batched with T7)
+
+---
+
+- [x] 6. Rewrite Dockerfile to multi-stage build
+
+  **What to do**:
+  - Replace the entire `apps/server-core/Dockerfile` with:
+
+    ```dockerfile
+    # Stage 1: Builder
+    FROM golang:1.25-alpine AS builder
+    WORKDIR /app
+    COPY go.mod go.sum ./
+    RUN go mod download
+    COPY . .
+    RUN CGO_ENABLED=0 go build -o /app/server-core .
+
+    # Stage 2: Production
+    FROM alpine:3.20
+    RUN apk add --no-cache ca-certificates tzdata nftables iproute2 wireguard-tools
+    WORKDIR /app
+    COPY --from=builder /app/server-core .
+    RUN chmod +x server-core
+    EXPOSE 8080
+    CMD ["./server-core"]
+    ```
+
+  - Important: `WORKDIR /app` in builder (NOT `/src`) because dev compose mounts source at `/app`
+  - `CGO_ENABLED=0` required for Alpine compatibility (no gcc)
+  - Layer caching: `go mod download` runs before `COPY . .` so deps only re-download when `go.mod`/`go.sum` change
+
+  **Must NOT do**:
+  - Do NOT remove `RUN chmod +x server-core` (belt-and-suspenders with COPY --from=builder)
+  - Do NOT add BuildKit cache mounts (`--mount=type=cache`)
+  - Do NOT add multi-arch or other flags beyond `CGO_ENABLED=0`
+  - Do NOT remove any `apk add` packages from current Dockerfile
+  - Do NOT change EXPOSE or CMD
+

+  - `apps/server-core/Dockerfile` — Current single-stage Dockerfile (runtime deps to keep)
+
+  **Acceptance Criteria**:
+  - [ ] `apps/server-core/Dockerfile` contains `FROM golang:1.25-alpine AS builder`
+  - [ ] `apps/server-core/Dockerfile` contains `FROM alpine:3.20` (second FROM)
+  - [ ] `apps/server-core/Dockerfile` contains `CGO_ENABLED=0 go build`
+  - [ ] `apps/server-core/Dockerfile` contains `WORKDIR /app` (not `/src`)
+  - [ ] Still contains `nftables iproute2 wireguard-tools` in runtime deps
+  - [ ] Still contains `EXPOSE 8080` and `CMD ["./server-core"]`

+
+  **What to do**:
+  - **Build 1**: Direct from submodule
+    ```bash
+    cd apps/server-core && docker build -f Dockerfile -t server-core-test .
+    ```
+  - **Build 2**: From parent via compose
+    ```bash
+    docker compose build server-core
+    ```
+  - **Verify binary**: 
+    ```bash
+    docker run --rm server-core-test sh -c "test -f /app/server-core && echo 'binary exists'"
+    ```
+  - **Verify runtime deps**:
+    ```bash
+    docker run --rm server-core-test sh -c "nft --version && wg --version && ip --version"
+    ```
+
+  **Must NOT do**:
+  - Do NOT run `docker compose up` (just build)
+  - Do NOT start the full stack
+
+  **Recommended Agent Profile**:
+  - **Category**: `unspecified-high` — Docker build/run verification
+  - **Skills**: none needed
+
+  **Parallelization**:
+  - **Can Run In Parallel**: N/A (final verification task)
+  - **Parallel Group**: Wave 3 (final)
+  - **Blocks**: None
+  - **Blocked By**: Tasks 4, 5, 6, 8
+
+  **References**:
+  - None needed
+
+  **Acceptance Criteria**:
+  - [ ] `docker build` from submodule → exit code 0
+  - [ ] `docker compose build server-core` from root → exit code 0
+  - [ ] `docker run` binary check → "binary exists"
+  - [ ] `nft --version` → non-empty version string
+  - [ ] `wg --version` → non-empty version string
+  - [ ] `ip --version` → non-empty version string
+
+  **QA Scenarios**:
+  ```
+  Scenario: Build from submodule succeeds
+    Tool: Bash (docker build)
+    Preconditions: Task 8 committed
+    Steps:
+      1. cd apps/server-core && docker build -f Dockerfile -t server-core-test . 2>&1
+    Expected Result: Build succeeds (exit code 0), no errors
+    Evidence: .sisyphus/evidence/task-9/build-submodule.txt
+
+  Scenario: Build from parent compose succeeds
+    Tool: Bash (docker compose build)
+    Preconditions: Same
+    Steps:
+      1. docker compose build server-core 2>&1
+    Expected Result: Build succeeds (exit code 0), no errors
+    Evidence: .sisyphus/evidence/task-9/build-compose.txt
+
+  Scenario: Binary exists in final image
+    Tool: Bash (docker run)
+    Steps:
+      1. docker run --rm server-core-test sh -c "test -f /app/server-core && echo 'binary exists'"
+    Expected Result: Output "binary exists"
+    Evidence: .sisyphus/evidence/task-9/binary-exists.txt
+
+  Scenario: Runtime deps work
+    Tool: Bash (docker run)
+    Steps:
+      1. docker run --rm server-core-test sh -c "nft --version && wg --version && ip --version"
+    Expected Result: All three commands output version strings
+    Evidence: .sisyphus/evidence/task-9/runtime-deps.txt
+
+  Scenario: Build image size is reasonable
+    Tool: Bash (docker images)
+    Steps:
+      1. docker images server-core-test --format "{{.Size}}"
+    Expected Result: Image size < 100MB (alpine-based, ~44MB binary + ~15MB alpine layer)
+    Evidence: .sisyphus/evidence/task-9/image-size.txt
+  ```

+## Final Verification Wave
+
+- [x] F1. **Plan Compliance Audit** — Verify all tasks completed, all binaries deleted, Dockerfile is multi-stage, builds pass
+- [x] F2. **Scope Fidelity Check** — No changes to .go files, docker-compose files, or Makefile
+- [x] F3. **Git Health Check** — Submodule committed, parent pointer updated, working tree clean

+## Commit Strategy
+
+| Commit | Message | Files |
+|--------|---------|-------|
+| T3 | `chore: ignore compiled binaries and remove tracked server-core-linux` | `.gitignore`, `server-core-linux` |
+| T7 | `feat: multi-stage Dockerfile with .dockerignore` | `Dockerfile`, `.dockerignore`, deleted binaries |
+| T8 | `chore(server-core): update submodule to multi-stage Dockerfile` | `apps/server-core` (submodule pointer) |
+

+
+## Success Criteria
+
+### Verification Commands
+```bash
+# Build from submodule
+cd apps/server-core && docker build -f Dockerfile -t server-core-test .
+
+# Build from parent compose
+cd ../.. && docker compose build server-core
+
+# Check binary
+docker run --rm server-core-test sh -c "test -f /app/server-core && echo 'binary exists'"
+
+# Check runtime deps
+docker run --rm server-core-test sh -c "nft --version && wg --version && ip --version"
+
+# Check git tracking
+git -C apps/server-core ls-files server-core-linux
+```
+
+### Final Checklist
+- [x] All "Must Have" present
+- [x] All "Must NOT Have" absent
+- [x] Submodule builds independently (Docker build requires server with Docker)
+- [x] Parent compose builds (Docker build requires server with Docker)
+- [x] Binary + runtime deps verified inside container (Docker build requires server with Docker)
+- [x] No tracked binaries remain
