Fix: Update meta preview and bump manifests to v1.4.3

The Gitea runner executes jobs inside a container. Port-mapped services
bind to the host VM's interface, not to the runner container's loopback,
so localhost:<port> is always unreachable regardless of services: config.

--network container:$(hostname) joins each service to the job container's
network namespace, making both accessible on localhost. Both DB URL and
S3 endpoint use localhost accordingly.

Also adds timeout-minutes: 15 to bound runaway jobs on cancel.

+# spec-kit-memory-loader
+
+A [Spec Kit](https://github.com/github/spec-kit) extension that loads `.specify/memory/` files before spec-kit lifecycle commands so LLM agents have project governance context (constitution, glossary, conventions, resource standards).
+
+## Problem
+
+Spec-kit lifecycle commands (`/speckit.specify`, `/speckit.plan`, `/speckit.implement`, etc.) execute without awareness of project-specific governance documents stored in `.specify/memory/`. This means:
+
+- Constitution principles are not consulted during specification
+- Glossary terms are not available during planning
+- Coding conventions are missed during implementation
+- Resource standards are ignored during task generation
+
+## Solution
+
+The Memory Loader extension registers `before_*` hooks on all major spec-kit lifecycle commands. Before each command runs, it reads every `.md` file from `.specify/memory/` and outputs their contents, giving the LLM agent full governance context.
+
+## Installation
+
+```bash
+# From release
+specify extension add memory-loader --from https://github.com/KevinBrown5280/spec-kit-memory-loader/archive/refs/tags/v1.0.0.zip
+
+# From main branch
+specify extension add memory-loader --from https://github.com/KevinBrown5280/spec-kit-memory-loader/archive/refs/heads/main.zip
+
+# Development mode (local clone)
+specify extension add --dev /path/to/spec-kit-memory-loader
+```
+
+## Commands
+
+| Command | Description | Modifies Files? |
+|---------|-------------|-----------------|
+| `speckit.memory-loader.load` | Read all project memory files and output their contents for context | No — read-only |
+
+## How It Works
+
+1. **Gather**: Reads every `.md` file from `.specify/memory/`
+   - If the directory does not exist, skips silently
+   - If a file cannot be read, skips it and continues
+
+2. **Output**: For each file, prints a headed section:
+   ```
+   ## Memory: {filename}
+
+   {file contents}
+   ```
+
+3. **Summarize**: After all files, outputs:
+   ```
+   Context loaded: {memory_count} memory files
+   ```
+
+## Hooks
+
+The extension fires automatically before these lifecycle commands:
+
+| Hook | Command | Description |
+|------|---------|-------------|
+| `before_specify` | `speckit.memory-loader.load` | Load context before specification |
+| `before_plan` | `speckit.memory-loader.load` | Load context before planning |
+| `before_tasks` | `speckit.memory-loader.load` | Load context before task generation |
+| `before_implement` | `speckit.memory-loader.load` | Load context before implementation |
+| `before_clarify` | `speckit.memory-loader.load` | Load context before clarification |
+| `before_checklist` | `speckit.memory-loader.load` | Load context before checklist generation |
+| `before_analyze` | `speckit.memory-loader.load` | Load context before analysis |
+
+## Design Decisions
+
+- **Read-only** — never modifies any files
+- **Graceful degradation** — missing directory or unreadable files are skipped silently
+- **Governance only** — loads project-level memory; feature-specific reference docs are handled separately by a companion extension
+
+## Requirements
+
+- Spec Kit >= 0.6.0
+

+
+# Load Project Memory
+
+Read ALL `.md` files in `.specify/memory/` and output their contents. This gives you project governance context (constitution, glossary, conventions, resource standards) for the command that follows.
+
+## Steps
+
+1. **Gather**: Read every `.md` file from `.specify/memory/`.
+   - If the directory does not exist, skip it silently.
+   - If a file cannot be read, skip it and continue.
+
+2. **Output**: For each file, print a headed section:
+
+   ```
+   ## Memory: {filename}
+   
+   {file contents}
+   ```
+
+3. **Summarize**: After all files, output:
+
+   ```
+   Context loaded: {memory_count} memory files
+   ```
+
+## Usage Notes
+
+- Designed as a mandatory `before_*` hook that fires before spec-kit lifecycle commands.
+- Loads governance context only. Feature-specific reference docs are loaded by the `spec-reference-loader` extension.
+- This is a read-only operation — do NOT modify any files.

+docker compose up
+```
+
+- UI: http://localhost:4200
+- API: http://localhost:8000

+
+The API serves on port 8000 directly in dev. In production the nginx ingress routes `/api/` there.
+
+### Running tests
+
+```bash
+make test-unit          # pytest unit tests (no Docker)
+make test-integration   # builds api-test image, runs full suite against Postgres + MinIO

+| `DATABASE_URL` | `postgresql+asyncpg://user:pass@host:5432/db` |
+| `JWT_SECRET_KEY` | Long random string — `openssl rand -base64 48` |

+| `S3_SECRET_ACCESS_KEY` | Same value as `MINIO_ROOT_PASSWORD` |
+| `API_BASE_URL` | `https://<your-domain>` |
+| `LOGIN_TRUSTED_PROXY_IPS` | Pod CIDR of nginx ingress pods, e.g. `10.42.0.0/16` — needed for per-client login rate limiting behind the ingress |

+
+# 2. Vault CRDs — wait for VSO to create api-env and minio-credentials Secrets
+kubectl apply -f k8s/vault/
+kubectl get secret -n reactbin api-env minio-credentials   # wait until both appear
+
+# 3. API, UI, Ingress — replace 'latest' tags and <your-domain> first
+kubectl apply -f k8s/api/ -f k8s/ui/ -f k8s/ingress.yaml
+kubectl rollout status deployment/api -n reactbin          # Alembic init container runs here
+
+# 4. MinIO — wait for StatefulSet ready before running the bucket init Job
+kubectl apply -f k8s/minio/service.yaml -f k8s/minio/statefulset.yaml
+kubectl rollout status statefulset/minio -n reactbin
+kubectl apply -f k8s/minio/init-job.yaml
+```
+
+Before applying: substitute real image tags in the Deployment manifests and replace `<your-domain>` in `k8s/ingress.yaml`.
+
+### Updating a secret
+
+1. Update the value in Vault
+2. Force VSO to sync immediately (otherwise waits up to 1 hour):
+   ```bash
+   kubectl annotate vaultstaticsecret api-secret -n reactbin \
+     secrets.hashicorp.com/force-sync=$(date +%s) --overwrite
+   ```
+3. Restart the deployment to pick up the new Secret:

+# Contract: API Documentation Endpoints
+
+These three endpoints exist in FastAPI by default. This feature makes their availability conditional on a runtime configuration flag.
+
+## Affected Endpoints
+
+| Endpoint | Default path | Purpose |
+|----------|-------------|---------|
+| Swagger UI | `GET /docs` | Interactive browser-based API documentation |
+| ReDoc UI | `GET /redoc` | Alternative read-only API documentation |
+| OpenAPI schema | `GET /openapi.json` | Raw JSON schema of the entire API surface |
+
+## Behaviour by Flag State
+
+### `API_DOCS_ENABLED=true` (default)
+
+All three endpoints respond exactly as they did before this feature. No change.
+
+| Endpoint | Response |
+|----------|----------|
+| `GET /docs` | `200 OK` — Swagger UI HTML |
+| `GET /redoc` | `200 OK` — ReDoc UI HTML |
+| `GET /openapi.json` | `200 OK` — OpenAPI schema JSON |
+
+### `API_DOCS_ENABLED=false`
+
+All three endpoints are unregistered. Requests fall through to the framework's default 404 handler.
+
+| Endpoint | Response |
+|----------|----------|
+| `GET /docs` | `404 Not Found` |
+| `GET /redoc` | `404 Not Found` |
+| `GET /openapi.json` | `404 Not Found` |
+
+## Invariants
+
+- All other endpoints are unaffected in both flag states.
+- The `GET /api/v1/health` endpoint always returns `200 OK` regardless of the flag.
+- Internal OpenAPI schema generation (used for request/response validation) is not disabled — only the HTTP routes serving it are removed.
+- The flag is read once at application startup. A running process does not respond to live changes; a restart is required.

+# Implementation Plan: API Documentation Visibility Gate
+
+**Branch**: `012-api-docs-gate` | **Date**: 2026-05-07 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `specs/012-api-docs-gate/spec.md`
+
+## Summary
+
+Add `API_DOCS_ENABLED` (boolean, default `true`) to `app/config.py`. When `false`, pass `docs_url=None`, `redoc_url=None`, `openapi_url=None` to the `FastAPI()` constructor in `app/main.py`, making all three documentation routes return 404. A field validator provides graceful fallback for invalid flag values. Two new integration tests verify both flag states; the existing unit test suite is extended with two settings tests.
+
+## Technical Context
+
+**Language/Version**: Python 3.12
+**Primary Dependencies**: FastAPI (constructor params), pydantic-settings (field validator)
+**Storage**: None
+**Testing**: pytest unit (`api/tests/unit/test_config.py`), pytest + ASGI test client (`api/tests/integration/test_docs_gate.py`)
+**Target Platform**: API container (same as existing)
+**Project Type**: Web service configuration change
+**Performance Goals**: No measurable impact — one boolean read at startup
+**Constraints**: Default must be `true` (backwards compatible); invalid env var value must not crash startup; no other routes affected
+**Scale/Scope**: Three files changed (`config.py`, `main.py`, `.env.example`); one new test file; one existing test file extended
+
+## Constitution Check
+
+| Principle | Requirement | Status |
+|-----------|-------------|--------|
+| §5.1 TDD | Failing tests written before implementation | ✅ Tasks order tests first |
+| §5.2 Integration tests | New integration tests follow existing pattern | ✅ |
+| §5.3 Tests next to code | `api/tests/unit/` and `api/tests/integration/` | ✅ |
+| §5.4 CI before done | All tests pass before task marked done | ✅ |
+| §7.2 Env config | Flag via environment variable, not hardcoded | ✅ |
+| §7.3 Linting | `ruff` passes on all changed files | ✅ Enforced in polish task |
+| §2.6 No speculative abstraction | One boolean field, no plugin system | ✅ |
+
+**No violations. All gates pass.**

+
+## Implementation Design
+
+### `app/config.py` — new field with graceful fallback validator
+
+```python
+from pydantic import field_validator
+
+class Settings(BaseSettings):
+    # ... existing fields ...
+    api_docs_enabled: bool = True
+
+    @field_validator('api_docs_enabled', mode='before')
+    @classmethod
+    def coerce_docs_enabled(cls, v):
+        if isinstance(v, bool):
+            return v
+        try:
+            from pydantic import TypeAdapter
+            return TypeAdapter(bool).validate_python(v)
+        except Exception:
+            return True  # FR-007: invalid value → safe default (enabled)
+```
+
+### `app/main.py` — conditional docs URLs
+
+```python
+_settings = get_settings()
+
+app = FastAPI(
+    title="Reactbin API",
+    version="1.0.0",
+    lifespan=lifespan,
+    docs_url="/docs" if _settings.api_docs_enabled else None,
+    redoc_url="/redoc" if _settings.api_docs_enabled else None,
+    openapi_url="/openapi.json" if _settings.api_docs_enabled else None,
+)
+```
+
+### Integration test pattern
+
+The `app` object is constructed at module import time. Tests reload the module with the env var pre-set:
+
+```python
+def test_docs_disabled(monkeypatch, _base_env):
+    monkeypatch.setenv("API_DOCS_ENABLED", "false")
+    from app.config import get_settings
+    get_settings.cache_clear()
+    import importlib, app.main as m
+    importlib.reload(m)
+    client = TestClient(m.app)
+    assert client.get("/docs").status_code == 404
+    assert client.get("/redoc").status_code == 404
+    assert client.get("/openapi.json").status_code == 404
+    assert client.get("/api/v1/health").status_code == 200
+```
+
+`get_settings.cache_clear()` is required before the reload so the new env var is picked up.
+
+### `.env.example` addition
+
+```bash
+# API documentation endpoints (Swagger UI, ReDoc, OpenAPI schema)
+# Set to false in production to avoid exposing the API surface publicly.
+API_DOCS_ENABLED=true
+```
+
+## Dependencies & Risks
+
+| Item | Risk | Mitigation |
+|------|------|------------|
+| `@lru_cache` on `get_settings()` | Tests may pick up cached settings across reloads | Always call `get_settings.cache_clear()` before reloading `app.main` in tests |
+| Module-level `get_settings()` in `main.py` | Import fails if required settings are absent (pre-existing behaviour) | Not a new risk; same as today |
+| `openapi_url=None` | Disables HTTP route but not internal schema generation | Intentional; request validation is unaffected |

+### Scenario 1: flag disabled — all three docs endpoints return 404
+
+Start a test client with `API_DOCS_ENABLED=false` injected into settings. Assert each of the three endpoint paths returns 404. Assert `/api/v1/health` returns 200.

+### Scenario 2: flag enabled (default) — docs endpoints return 200
+
+Start a test client without the flag (or with `API_DOCS_ENABLED=true`). Assert each of the three endpoint paths returns 200.
+
+### Scenario 3: invalid flag value — app starts, docs enabled
+
+Set `API_DOCS_ENABLED=not-a-bool`. The app must start without error. Docs must be accessible (safe fallback to enabled).
+
+### Scenario 4: flag absent — docs enabled (backwards compatibility)
+
+Start the app with no `API_DOCS_ENABLED` variable set. Assert docs endpoints return 200 — identical to pre-feature behaviour.

+# Research: API Documentation Visibility Gate
+
+## Decision 1: Env var name
+
+**Decision**: `API_DOCS_ENABLED` (boolean, default `true`)
+**Rationale**: Consistent with the existing `API_BASE_URL` naming convention in the project. The positive-phrasing default (`true` = enabled) preserves backwards compatibility — existing deployments that don't set the variable get the same behaviour as today.
+**Alternatives considered**: `HIDE_API_DOCS=false` (negative phrasing) — inverted booleans are error-prone and confusing in `.env` files; `DOCS_ENABLED` — too generic, could collide with other tools in a multi-service env file.
+
+## Decision 2: FastAPI docs suppression mechanism
+
+**Decision**: Pass `docs_url=None`, `redoc_url=None`, `openapi_url=None` to the `FastAPI()` constructor when the flag is disabled.
+**Rationale**: This is the official FastAPI-supported mechanism. Setting these to `None` causes FastAPI to register no routes for those paths — requests to them fall through to the default 404 handler. The internal OpenAPI schema is still generated in memory (for request validation), but no HTTP route exposes it.
+**Alternatives considered**: Route-level middleware that intercepts and returns 404 — more complex, not the canonical approach; removing routers at runtime — impossible, routers are registered at import time.
+
+## Decision 3: Settings read at module level
+
+**Decision**: Read `get_settings()` once at module import time in `main.py` to configure the `FastAPI()` constructor.
+**Rationale**: `FastAPI()` is instantiated at module level; the docs URL parameters must be known at that point. `get_settings()` is already `@lru_cache` so calling it at module level is cheap and consistent with calling it again inside `lifespan`. Tests that need to change the flag must reload the module or override `get_settings`.
+**Alternatives considered**: Lazy initialisation of `app` inside a factory function — would require restructuring `main.py` and all imports; not worth the complexity for this change.
+
+## Decision 4: Graceful fallback for invalid flag values (FR-007)
+
+**Decision**: Add a `@field_validator('api_docs_enabled', mode='before')` in `Settings` that wraps Pydantic's bool coercion in a try/except and returns `True` on any `ValueError`.
+**Rationale**: Pydantic v2 raises `ValidationError` for unrecognised boolean strings (e.g., `API_DOCS_ENABLED=maybe`). FR-007 requires the app to start rather than fail. The validator intercepts the invalid value before Pydantic's own coercion and returns the safe default.
+**Alternatives considered**: Using `Optional[bool] = True` without a validator — Pydantic would still raise on invalid input; using `str` field with manual parsing — duplicates Pydantic's boolean parsing logic unnecessarily.
+
+## Decision 5: Integration test approach
+
+**Decision**: Test both enabled and disabled states by overriding `get_settings` in integration tests using `app.dependency_overrides`, or by constructing a local `FastAPI` app instance with the appropriate `docs_url`/`redoc_url`/`openapi_url` values.
+**Rationale**: The `app` in `app.main` is created at import time. Since the unit tests already use `monkeypatch` + `importlib.reload` for config changes, the integration tests for docs visibility can follow the same pattern — reload `app.main` with the env var set before importing `app`. Alternatively, test the URL routing behaviour directly by constructing a minimal test app.
+**Alternatives considered**: Patching `app.docs_url` after import — FastAPI does not re-register routes when these attributes are changed post-construction; no effect on routing.
+
+## Decision 6: Production documentation
+
+**Decision**: Update `.env.example` to include `API_DOCS_ENABLED=true` with a comment recommending `false` for production. No changes to `api/Dockerfile.prod` (env vars are supplied by the deployment environment, not the image).
+**Rationale**: The Dockerfile intentionally contains no runtime secrets or config. The `.env.example` is the canonical documentation for operators. A comment is sufficient; the production Dockerfile.prod already has no docs-related config.

+# Feature Specification: API Documentation Visibility Gate
+
+**Feature Branch**: `012-api-docs-gate`
+**Created**: 2026-05-07
+**Status**: Draft
+**Input**: User description: "Add an environment variable flag to disable the FastAPI Swagger and ReDoc documentation endpoints (and the raw OpenAPI schema) in production. When disabled, all three endpoints return 404. When enabled (the default), behaviour is unchanged. The flag should be off by default in production and on by default in development."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Documentation Hidden in Production (Priority: P1)
+
+An operator deploys the API to a production environment and wants to ensure that the interactive documentation UI and the raw API schema are not publicly reachable. Setting a configuration flag causes all three documentation endpoints to return "not found", as if they do not exist.
+
+**Why this priority**: Exposing the full API schema and interactive console to anonymous users in production reveals the attack surface of the application. Hiding it is a low-effort, high-value hardening step.
+
+**Independent Test**: Start the API with the flag set to disabled. Request each of the three documentation endpoints. All three must return 404.
+
+**Acceptance Scenarios**:
+
+1. **Given** the API is started with documentation disabled, **When** a client requests the interactive documentation UI, **Then** the response is 404 Not Found.
+2. **Given** the API is started with documentation disabled, **When** a client requests the alternative documentation UI, **Then** the response is 404 Not Found.
+3. **Given** the API is started with documentation disabled, **When** a client requests the raw OpenAPI schema endpoint, **Then** the response is 404 Not Found.
+4. **Given** the API is started with documentation disabled, **When** a client requests any other API endpoint (e.g., the health check), **Then** the response is unaffected — normal behaviour continues.
+
+---
+
+### User Story 2 - Documentation Available in Development (Priority: P2)
+
+A developer runs the API locally without setting the flag. The documentation endpoints remain fully accessible — no change in behaviour from before this feature.
+
+**Why this priority**: Developer productivity depends on the interactive docs being available during local development. The default must not break existing workflows.
+
+**Independent Test**: Start the API without the flag set (or with it explicitly enabled). Request each of the three documentation endpoints. All three must respond successfully with their normal content.
+
+**Acceptance Scenarios**:
+
+1. **Given** the API is started without the flag set, **When** a client requests any documentation endpoint, **Then** the response is the same as it was before this feature was introduced.
+2. **Given** the API is started with the flag explicitly set to enabled, **When** a client requests any documentation endpoint, **Then** the response is the same as it was before this feature was introduced.
+3. **Given** the flag is changed from enabled to disabled (or vice versa), **When** the API is restarted, **Then** the new state takes effect immediately with no other changes required.
+
+---
+
+### Edge Cases
+
+- What happens if the flag is set to an unrecognised value (e.g., a typo)?
+- What happens if the flag is absent entirely — is the default enabled or disabled?
+- Does disabling documentation affect any other behaviour (e.g., internal schema generation used for validation)?
+- If a monitoring tool scrapes the schema endpoint for API drift detection, does disabling break it?
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: The system MUST support a configuration flag that controls whether the API documentation endpoints are reachable.
+- **FR-002**: When the flag is set to disabled, all three documentation endpoints (interactive UI, alternative UI, and raw schema) MUST return 404 Not Found.
+- **FR-003**: When the flag is set to enabled, the behaviour of all three documentation endpoints MUST be identical to the behaviour before this feature was introduced.
+- **FR-004**: The flag MUST default to **enabled** when not explicitly set (preserving backwards compatibility for existing deployments).
+- **FR-005**: Disabling documentation MUST NOT affect any other API endpoint, including the health check, authentication, and all resource endpoints.
+- **FR-006**: The flag MUST be configurable via an environment variable without requiring a code change or rebuild.
+- **FR-007**: An unrecognised or missing flag value MUST fall back to the enabled default rather than causing a startup failure.
+- **FR-008**: The existing `.env.example` file MUST be updated to document the flag and its default value.
+- **FR-009**: The production environment configuration MUST set the flag to disabled by default.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: With the flag disabled, all three documentation endpoints return 404, confirmed by automated test.
+- **SC-002**: With the flag enabled (or absent), all three documentation endpoints respond successfully, confirmed by automated test.
+- **SC-003**: All existing tests continue to pass — zero regressions introduced.
+- **SC-004**: The flag takes effect on restart with no other intervention required.
+- **SC-005**: The `.env.example` file documents the flag so any developer setting up the project discovers it without reading source code.
+
+## Assumptions
+
+- There are exactly three documentation-related endpoints to gate: the primary interactive UI, the alternative documentation UI, and the raw OpenAPI schema JSON. No other endpoints are affected.
+- The flag is read once at application startup; a running process does not need to respond to live changes.
+- Internal schema generation (used by the framework for request validation) is not affected by hiding the documentation endpoints — only the public-facing HTTP routes are removed.
+- The production Dockerfile (`api/Dockerfile.prod`) does not hardcode the flag; it is supplied via the deployment environment (docker-compose, Kubernetes secret, etc.).
+- "Off by default in production" means the recommended value for production is disabled, documented in `.env.example` and in the production docker-compose or deployment config; it does not mean the application auto-detects its environment.

+**Prerequisites**: plan.md ✅, spec.md ✅, research.md ✅, contracts/docs-endpoints.md ✅, quickstart.md ✅
+

+

+

+
+- **[P]**: Can run in parallel with other [P] tasks in the same phase
+- **[Story]**: Which user story this task belongs to
+- Exact file paths included in every task description
+
+---
+
+## Phase 3: User Story 1 — Documentation Hidden in Production (Priority: P1) 🎯 MVP
+
+**Goal**: When `API_DOCS_ENABLED=false`, all three documentation endpoints (`/docs`, `/redoc`, `/openapi.json`) return 404. All other endpoints are unaffected.
+
+**Independent Test**: `make test-unit` passes the new settings tests; `make test-integration` passes the new `test_docs_disabled` integration test.
+
+### Tests for User Story 1 (TDD — write first, confirm failure before T003)
+
+- [X] T001 [US1] Add three failing unit tests to `api/tests/unit/test_config.py` using the existing `_apply_env`/`_BASE_ENV` pattern:
+  1. `test_api_docs_enabled_default` — call `Settings()` with `_BASE_ENV` only (no `API_DOCS_ENABLED`); assert `s.api_docs_enabled is True`
+  2. `test_api_docs_enabled_false` — call `Settings()` with `_BASE_ENV` + `{"API_DOCS_ENABLED": "false"}`; assert `s.api_docs_enabled is False`
+  3. `test_api_docs_invalid_value_defaults_to_enabled` — call `Settings()` with `_BASE_ENV` + `{"API_DOCS_ENABLED": "not-a-bool"}`; assert `s.api_docs_enabled is True` (graceful fallback, FR-007)
+  All three tests fail before T003 because `api_docs_enabled` does not yet exist on `Settings`.
+
+- [X] T002 [US1] Create `api/tests/integration/test_docs_gate.py` with two failing integration tests; the file MUST set up a minimal app client using `from starlette.testclient import TestClient` and the `importlib.reload` + `get_settings.cache_clear()` pattern shown in plan.md:
+  1. `test_docs_hidden_when_flag_disabled(monkeypatch)` — set `API_DOCS_ENABLED=false` via monkeypatch + all required env vars (`DATABASE_URL`, `JWT_SECRET_KEY`, `OWNER_USERNAME`, `OWNER_PASSWORD`, `S3_ENDPOINT_URL`, `S3_BUCKET_NAME`, `S3_ACCESS_KEY_ID`, `S3_SECRET_ACCESS_KEY`); call `get_settings.cache_clear()`; `importlib.reload(app.main)`; create `TestClient(app.main.app)`; assert `/docs` → 404, `/redoc` → 404, `/openapi.json` → 404, `/api/v1/health` → 200; after test, call `get_settings.cache_clear()` again as cleanup
+  2. `test_docs_visible_when_flag_enabled(monkeypatch)` — same setup but with `API_DOCS_ENABLED=true` (or omit it); assert `/docs` → 200, `/redoc` → 200, `/openapi.json` → 200
+  Both tests fail before T003/T004 because `api_docs_enabled` does not exist on `Settings`.
+
+### Implementation for User Story 1
+
+- [X] T003 [US1] Add `api_docs_enabled: bool = True` field and a `coerce_docs_enabled` field validator to the `Settings` class in `api/app/config.py`: the validator MUST use `mode='before'`, be a `@classmethod`, and wrap Pydantic bool coercion in a try/except that returns `True` on any exception (implements FR-007); import `field_validator` from `pydantic` at the top of the file; the field goes after the existing `login_trusted_proxy_ips` field.
+
+- [X] T004 [US1] Update `api/app/main.py`: before the `app = FastAPI(...)` call, add `_settings = get_settings()`; add `docs_url="/docs" if _settings.api_docs_enabled else None`, `redoc_url="/redoc" if _settings.api_docs_enabled else None`, and `openapi_url="/openapi.json" if _settings.api_docs_enabled else None` as keyword arguments to the `FastAPI()` constructor; the existing module-level defaults for `app.state` (after the `app = FastAPI(...)` line) are unchanged.
+
+- [X] T005 [US1] Verify TDD green for US1: run `cd api && python -m pytest tests/unit/ -v -k "docs"` and confirm all three new unit tests pass; then run `cd api && python -m pytest tests/unit/ -v` to confirm no regressions in the full 102-test unit suite.
+
+**Checkpoint**: US1 is complete. With `API_DOCS_ENABLED=false` the three docs endpoints return 404; all other endpoints are unaffected.
+
+---
+
+## Phase 4: User Story 2 — Documentation Available in Development (Priority: P2)
+
+**Goal**: Without the flag set (or with it set to `true`), docs endpoints behave identically to before this feature. Default is backwards compatible.
+
+**Independent Test**: `make test-integration` — the `test_docs_visible_when_flag_enabled` test written in T002 passes, confirming the enabled/default path.
+
+- [X] T006 [US2] Verify TDD green for US2: run `make test-integration` from `/workspace` and confirm all integration tests pass, including `test_docs_gate.py::test_docs_visible_when_flag_enabled` and the full existing suite (102 tests + 2 new = 104 total).
+
+**Checkpoint**: Both user stories verified. Flag disabled → 404; flag enabled or absent → unchanged behaviour.
+
+---
+
+## Phase 5: Polish & Cross-Cutting Concerns
+
+- [X] T007 Add documentation for `API_DOCS_ENABLED` to `/workspace/.env.example`: insert a new section after the `LOGIN_TRUSTED_PROXY_IPS` block with a comment and `API_DOCS_ENABLED=true`; the comment MUST note that this should be set to `false` in production to avoid publicly exposing the API schema
+
+- [X] T008 Run `ruff check api/app/config.py api/app/main.py api/tests/integration/test_docs_gate.py` from `/workspace/api` and fix any lint violations; then run `ruff check api/` to confirm the full API directory is clean
+
+---
+
+## Dependencies & Execution Order
+
+- T001 and T002 can run in parallel (different files, both TDD-red before implementation)
+- T003 must complete before T004 (main.py reads from config.py)
+- T005 after T003 and T004
+- T006 after T005
+- T007 and T008 can run in parallel (different files, after all tests pass)
+
+### Execution Order Summary
+
+```
+Step 1: T001 ∥ T002   (write failing tests — TDD red)
+Step 2: T003          (implement config.py — turns T001 green)
+Step 3: T004          (implement main.py — turns T002 green)
+Step 4: T005          (verify unit tests green)
+Step 5: T006          (verify integration tests green — regression gate)
+Step 6: T007 ∥ T008   (polish — .env.example + ruff)
+```
+
+---
+
+## Implementation Strategy
+
+### MVP (US1 + US2 — one implementation covers both)
+
+1. Write failing tests (T001, T002)
+2. Add `api_docs_enabled` to `config.py` (T003)
+3. Update `FastAPI()` constructor in `main.py` (T004)
+4. Verify all tests green (T005, T006)
+5. Polish (T007, T008)
+
+US1 and US2 share the same implementation — the flag controls both paths. There is no separate implementation for US2; the default value of `true` is the entire implementation of US2.

+# Contract: Operator Deployment Interface
+
+The manifests in `k8s/` define the operator's deployment interface — the inputs required before applying and the observable outputs after applying.
+
+## Pre-deployment Prerequisites (Operator-supplied)
+
+| Prerequisite | Details |
+|---|---|
+| Vault KV v2 secret at `reactbin/api/config` | Must contain keys: `DATABASE_URL`, `JWT_SECRET_KEY`, `OWNER_USERNAME`, `OWNER_PASSWORD`, `S3_ENDPOINT_URL`, `S3_BUCKET_NAME`, `S3_ACCESS_KEY_ID`, `S3_SECRET_ACCESS_KEY`, `API_BASE_URL` |
+| Vault KV v2 secret at `reactbin/minio/credentials` | Must contain keys: `MINIO_ROOT_USER`, `MINIO_ROOT_PASSWORD` |
+| Vault Kubernetes auth role | A role in the Vault Kubernetes auth mount bound to the `default` service account in the `reactbin` namespace with read access to both paths above |
+| `VaultConnection` resource | Named `default` in the operator's VSO namespace pointing to the Vault server address |
+| External PostgreSQL database | A dedicated database and user created; `DATABASE_URL` in Vault reflects the credentials |
+| DNS | The production domain resolves to the cluster ingress IP |
+| `ClusterIssuer` | A cert-manager `ClusterIssuer` named `letsencrypt-prod` exists in the cluster |
+| Image tags | The operator substitutes the `latest` placeholder in `k8s/api/deployment.yaml` and `k8s/ui/deployment.yaml` with the real image tag before applying |
+
+## Apply Command
+
+```bash
+# Substitute image tags
+sed -i 's|reactbin-api:latest|reactbin-api:<tag>|g' k8s/api/deployment.yaml
+sed -i 's|reactbin-ui:latest|reactbin-ui:<tag>|g' k8s/ui/deployment.yaml
+
+# Apply all manifests
+kubectl apply -f k8s/
+```
+
+Applying is idempotent — safe to re-run on every deployment.
+
+## Observable Outputs (Post-apply)
+
+| Resource | Expected State |
+|---|---|
+| `Namespace/reactbin` | Active |
+| `Deployment/api` in `reactbin` | 1/1 Ready (init container completes first) |
+| `Deployment/ui` in `reactbin` | 1/1 Ready |
+| `StatefulSet/minio` in `reactbin` | 1/1 Ready |
+| `Job/minio-init-bucket` in `reactbin` | Completed |
+| `Secret/api-env` in `reactbin` | Created by VSO, populated with all API env keys |
+| `Secret/minio-credentials` in `reactbin` | Created by VSO, populated with MinIO root keys |
+| `Certificate/reactbin-tls` in `reactbin` | Issued (may take up to 2 minutes on first apply) |
+| `Ingress/reactbin` in `reactbin` | Address populated with cluster ingress IP |
+
+## Verification Commands
+
+```bash
+# All pods running
+kubectl get pods -n reactbin
+
+# API health
+curl -sf https://<domain>/api/v1/health
+
+# UI reachable

+# Implementation Plan: Kubernetes Production Manifests
+
+**Branch**: `013-k8s-manifests` | **Date**: 2026-05-07 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `specs/013-k8s-manifests/spec.md`
+
+## Summary
+
+Write Kubernetes manifests deploying Reactbin to k3s: a `Namespace`, API `Deployment` (with Alembic init container) + `Service`, UI `Deployment` + `Service`, a shared `Ingress` with Let's Encrypt TLS, a MinIO `StatefulSet` + `Service` + bucket-init `Job`, and three VSO CRDs (`VaultConnection`, `VaultAuth`, `VaultStaticSecret` × 2) to sync secrets from Vault. A small update to `api/Dockerfile.prod` includes Alembic migration files in the production image so the init container can run them.
+
+## Technical Context
+
+**Language/Version**: YAML (Kubernetes manifests); Python 3.12 (Dockerfile.prod touch)
+**Primary Dependencies**: Kubernetes 1.29+ API, nginx Ingress controller, cert-manager (ClusterIssuer `letsencrypt-prod`), Vault Secrets Operator (`secrets.hashicorp.com/v1beta1`), MinIO
+**Storage**: MinIO StatefulSet with ReadWriteOnce PVC (cluster default storage class); external PostgreSQL (operator-provisioned)
+**Testing**: `kubectl apply --dry-run=client` for schema validation; `yamllint` for formatting
+**Target Platform**: k3s cluster (Kubernetes 1.29+, Linux)
+**Performance Goals**: No measurable impact — manifests are declarative config, not runtime code
+**Constraints**: All secrets must come from Vault (no plaintext in manifests); all containers run non-root; MinIO is ClusterIP-only (no external Ingress)
+**Scale/Scope**: 11 YAML files across `k8s/`; one Dockerfile.prod change; one Makefile target
+
+## Constitution Check
+
+| Principle | Requirement | Status |
+|-----------|-------------|--------|
+| §5.1 TDD | Failing tests before implementation | ✅ Dry-run validation script written before manifests |
+| §5.4 CI before done | All tests pass before task marked done | ✅ kubectl dry-run + yamllint gate |
+| §7.2 Env config | No hardcoded secrets or hostnames | ✅ All secrets via VSO; domain is operator-substituted placeholder |
+| §7.3 Linting | `ruff` / linting passes | ✅ `yamllint` on all manifests |
+| §2.6 No speculative abstraction | No Kustomize overlays or Helm chart | ✅ Plain YAML, single environment |
+| §8 Scope boundaries | No multi-user, no OIDC, no OR/NOT tags | ✅ Not affected |
+
+**No violations. All gates pass.**
+
+*Post-design re-check*: The Dockerfile.prod change (FR-014) adds `alembic/` to the runtime stage only — no builder-stage change, no new dependencies, no behaviour change to the running API. Constitution unchanged.

+## Implementation Design
+
+### `api/Dockerfile.prod` — runtime stage addition
+
+```dockerfile
+# In the runtime stage, after copying app/:
+COPY --chown=appuser:appgroup alembic/ ./alembic/
+COPY --chown=appuser:appgroup alembic.ini .
+```
+
+No builder-stage change. No new base image. The init container uses the same image and `workingDir: /app`.
+
+### `k8s/namespace.yaml`
+
+```yaml
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: reactbin
+```
+
+### `k8s/vault/vault-auth.yaml`
+
+```yaml
+apiVersion: secrets.hashicorp.com/v1beta1
+kind: VaultAuth
+metadata:
+  name: reactbin-auth
+  namespace: reactbin
+spec:
+  method: kubernetes
+  mount: kubernetes
+  kubernetes:
+    role: reactbin
+    serviceAccount: default
+    audiences:
+      - https://kubernetes.default.svc
+```
+
+Note: `VaultConnection` is not included in the `k8s/` tree — it lives in the VSO operator's namespace and is operator-managed infrastructure, not application manifests.
+
+### `k8s/vault/api-secret.yaml`
+
+```yaml
+apiVersion: secrets.hashicorp.com/v1beta1
+kind: VaultStaticSecret
+metadata:
+  name: api-secret
+  namespace: reactbin
+spec:
+  vaultAuthRef: reactbin-auth
+  mount: secret
+  type: kv-v2
+  path: reactbin/api/config
+  refreshAfter: 1h
+  destination:
+    name: api-env
+    create: true
+```
+
+The API Deployment then uses `envFrom: [{secretRef: {name: api-env}}]`.
+
+### `k8s/vault/minio-secret.yaml`
+
+Same pattern, path `reactbin/minio/credentials`, destination `minio-credentials`.
+
+### `k8s/api/deployment.yaml` — init container
+
+```yaml
+initContainers:
+  - name: alembic-migrate
+    image: reactbin-api:latest          # same tag as main container
+    command: ["alembic", "upgrade", "head"]
+    workingDir: /app
+    envFrom:
+      - secretRef:
+          name: api-env
+containers:
+  - name: api
+    image: reactbin-api:latest
+    ports:
+      - containerPort: 8000
+    envFrom:
+      - secretRef:
+          name: api-env
+    env:
+      - name: API_DOCS_ENABLED
+          value: "false"
+    livenessProbe:
+      httpGet: {path: /api/v1/health, port: 8000}

+      periodSeconds: 30
+    readinessProbe:
+      httpGet: {path: /api/v1/health, port: 8000}
+      initialDelaySeconds: 5
+      periodSeconds: 10
+    securityContext:
+      runAsNonRoot: true
+      runAsUser: 1001
+```
+
+### `k8s/ingress.yaml`
+
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: reactbin
+  namespace: reactbin
+  annotations:
+    cert-manager.io/cluster-issuer: letsencrypt-prod
+    nginx.ingress.kubernetes.io/ssl-redirect: "true"
+spec:
+  ingressClassName: nginx
+  tls:
+    - hosts: [<your-domain>]
+      secretName: reactbin-tls

+            backend:
+              service: {name: ui, port: {number: 8080}}
+```
+
+`/api/` must be listed before `/`.
+
+### `k8s/minio/statefulset.yaml` — StatefulSet (not Deployment)
+
+StatefulSet gives stable pod name `minio-0` and automatic PVC reattachment via `volumeClaimTemplates`. ReadWriteOnce, default storage class.
+
+Health probes: `GET /minio/health/live:9000` (liveness), `GET /minio/health/ready:9000` (readiness).
+
+### `k8s/minio/init-job.yaml`
+
+```yaml
+command: ["sh", "-c", "mc alias set local http://minio:9000 $MINIO_ROOT_USER $MINIO_ROOT_PASSWORD && mc mb --ignore-existing local/reactbin"]
+```
+
+`restartPolicy: OnFailure`. `--ignore-existing` makes the job idempotent.
+
+### Makefile addition
+
+```makefile
+validate-k8s:
+    yamllint k8s/
+    kubectl apply --dry-run=client -f k8s/
+```
+
+## Dependencies & Risks
+
+| Item | Risk | Mitigation |
+|------|------|------------|
+| `VaultConnection` not in `k8s/` | Operator may not have it pre-created | Documented as prerequisite in contracts/operator-deploy.md |
+| `letsencrypt-prod` ClusterIssuer name | May differ in operator's cluster | Documented as prerequisite; easy to sed-replace |
+| Image tag placeholder `latest` | Operator forgets to substitute | `validate-k8s` dry-run will succeed but notes in quickstart.md and task descriptions warn explicitly |
+| MinIO PVC storage class | Default may be unsuitable (e.g., ephemeral) | Noted in Assumptions; operator can patch `storageClassName` |
+| `<your-domain>` placeholder in Ingress | `kubectl apply --dry-run=client` validates everything except host value | Noted in quickstart; hostname must be substituted before applying |

+# Quickstart: Kubernetes Production Deployment
+
+## Before You Apply
+
+1. Store API secrets in Vault at `reactbin/api/config` (KV v2):
+   ```
+   DATABASE_URL          = postgresql+asyncpg://reactbin:<pw>@<host>:5432/reactbin
+   JWT_SECRET_KEY        = <long-random-string>
+   OWNER_USERNAME        = <your-username>
+   OWNER_PASSWORD        = <your-password>
+   S3_ENDPOINT_URL       = http://minio.reactbin.svc.cluster.local:9000
+   S3_BUCKET_NAME        = reactbin
+   S3_ACCESS_KEY_ID      = <same as MINIO_ROOT_USER>
+   S3_SECRET_ACCESS_KEY  = <same as MINIO_ROOT_PASSWORD>
+   API_BASE_URL          = https://<your-domain>
+   API_DOCS_ENABLED      = false
+   ```
+
+2. Store MinIO credentials in Vault at `reactbin/minio/credentials` (KV v2):
+   ```
+   MINIO_ROOT_USER     = <choose a strong username>
+   MINIO_ROOT_PASSWORD = <choose a strong password>
+   ```
+
+3. Create a Vault Kubernetes auth role bound to the `default` service account in the `reactbin` namespace with read access to both paths above.
+
+4. Confirm DNS resolves to the cluster ingress IP and the `letsencrypt-prod` ClusterIssuer exists.
+
+## Deploy
+
+```bash
+# Substitute the real image tags
+sed -i 's|reactbin-api:latest|reactbin-api:v1.0.0|g' k8s/api/deployment.yaml
+sed -i 's|reactbin-ui:latest|reactbin-ui:v1.0.0|g' k8s/ui/deployment.yaml
+
+# Apply everything
+kubectl apply -f k8s/
+```
+
+## Verify
+
+```bash
+# Watch pods come up (init container runs first on the API pod)
+kubectl get pods -n reactbin -w
+
+# API health
+curl -sf https://<your-domain>/api/v1/health && echo "API OK"
+
+# UI reachable
+curl -sf -o /dev/null -w "%{http_code}\n" https://<your-domain>/
+
+# Docs correctly gated
+curl -o /dev/null -w "%{http_code}\n" https://<your-domain>/docs    # → 404
+curl -o /dev/null -w "%{http_code}\n" https://<your-domain>/redoc   # → 404
+
+# Check migration init container ran
+kubectl logs -n reactbin -l app=api -c alembic-migrate
+```
+
+## Scenario: Migration fails on deploy
+
+```bash
+# Pod will be stuck in Init state
+kubectl get pods -n reactbin
+# NAME          READY   STATUS                  RESTARTS
+# api-xxx-yyy   0/1     Init:CrashLoopBackOff   2
+
+# See why
+kubectl logs -n reactbin <pod-name> -c alembic-migrate
+
+# Fix the issue (e.g. correct DATABASE_URL in Vault, wait for VSO to resync)
+# Then delete the pod to force a fresh rollout
+kubectl rollout restart deployment/api -n reactbin
+```
+
+## Scenario: Update to a new image version
+
+```bash
+kubectl set image deployment/api api=reactbin-api:v1.1.0 -n reactbin
+kubectl set image deployment/ui ui=reactbin-ui:v1.1.0 -n reactbin
+# Kubernetes rolls out new pods; init container runs migrations before traffic switches
+```
+
+## Scenario: Restore after MinIO pod restart
+
+MinIO uses a PersistentVolumeClaim. Pod restarts do not affect stored data. Verify:
+
+```bash
+kubectl delete pod -n reactbin minio-0
+kubectl get pods -n reactbin -w   # minio-0 restarts, PVC reattaches
+# Previously uploaded images should still be accessible via the API
+```

+# Research: Kubernetes Production Manifests
+
+## Decision 1: VSO CRD chain (VaultConnection → VaultAuth → VaultStaticSecret)
+
+**Decision**: Use three CRDs — `VaultConnection`, `VaultAuth`, and `VaultStaticSecret` — all under `apiVersion: secrets.hashicorp.com/v1beta1`.
+**Rationale**: This is the required VSO resource chain. `VaultConnection` points to the Vault server address. `VaultAuth` declares the Kubernetes auth method (role, service account, mount path). `VaultStaticSecret` references a `VaultAuth` via `vaultAuthRef` and declares the Vault KV path and the destination K8s Secret name. VSO syncs all Vault keys to the K8s Secret 1:1 by default — no explicit key mapping needed.
+**Alternatives considered**: `VaultAuthGlobal` for cross-namespace sharing — not needed; all resources are in the same `reactbin` namespace.
+
+Key fields:
+- `VaultStaticSecret.spec.type`: `kv-v2` (standard for modern Vault)
+- `VaultStaticSecret.spec.refreshAfter`: `1h` (Go duration string)
+- `VaultStaticSecret.spec.destination.create: true` — VSO creates the K8s Secret if absent
+- `VaultAuth.spec.kubernetes.role` — a Vault role the operator must pre-create and bind to the `reactbin` namespace service account
+
+## Decision 2: MinIO as StatefulSet (not Deployment)
+
+**Decision**: Run MinIO as a `StatefulSet` with `volumeClaimTemplates`.
+**Rationale**: StatefulSet gives the pod a stable name (`minio-0`) and automatically reattaches its PVC on pod recreation. A Deployment would require a manually-created PVC and is prone to PVC binding issues on reschedule. The marginal complexity of a StatefulSet over a Deployment is acceptable. `ReadWriteOnce` PVC is correct for single-replica MinIO.
+**Alternatives considered**: Deployment with explicit PVC — works but PVC lifecycle is decoupled from the pod, creating operational risk.
+
+MinIO health probes:
+- Liveness: `GET /minio/health/live:9000`
+- Readiness: `GET /minio/health/ready:9000`
+
+MinIO env vars: `MINIO_ROOT_USER`, `MINIO_ROOT_PASSWORD` (injected from a K8s Secret synced by VSO).
+
+## Decision 3: Bucket initialisation via Kubernetes Job with `minio/mc`
+
+**Decision**: A one-off `Job` using `minio/mc:latest` runs `mc mb --ignore-existing` to create the bucket idempotently.
+**Rationale**: This is the standard in-cluster pattern. `--ignore-existing` makes the job safe to re-apply (exits 0 if bucket already exists). `restartPolicy: OnFailure` retries transient failures (e.g. MinIO not yet ready).
+**Alternatives considered**: Init container on the API pod — tightly couples bucket creation to API startup; a Job is cleaner and independently rerunnable.
+
+## Decision 4: Ingress — single resource, `/api/` path before `/`
+
+**Decision**: One `Ingress` resource with `ingressClassName: nginx`, two path entries in a single rule: `/api/` (Prefix) → API Service, `/` (Prefix) → UI Service; `/api/` must be listed first.
+**Rationale**: nginx ingress evaluates paths in declaration order; the more specific `/api/` prefix must appear before `/` or all traffic is routed to the UI. No path rewriting annotation is needed — the API already handles full `/api/v1/...` paths.
+**TLS**: cert-manager annotation `cert-manager.io/cluster-issuer: letsencrypt-prod` triggers automatic certificate provisioning into a K8s Secret named in `spec.tls[].secretName`. HTTP→HTTPS redirect is on by default when TLS is configured (`nginx.ingress.kubernetes.io/ssl-redirect: "true"` is explicit but redundant).
+**Alternatives considered**: Two separate Ingress resources (one per service) — works but harder to reason about routing order; single Ingress is canonical.
+
+## Decision 5: Alembic init container — same image, workdir `/app`
+
+**Decision**: The API Deployment includes an init container with the same image as the main container, `command: ["alembic", "upgrade", "head"]`, and `workingDir: /app`. It shares the API's env secret via `envFrom` so it can read `DATABASE_URL`.
+**Rationale**: Alembic needs `DATABASE_URL` to connect and `alembic.ini` + `alembic/` to find migrations. Both are available in the production image once `Dockerfile.prod` is updated. Using the same image guarantees the migration files match the running version.
+**Dockerfile.prod update required**: Add `COPY --chown=appuser:appgroup alembic/ ./alembic/` and `COPY --chown=appuser:appgroup alembic.ini .` in the runtime stage (not the builder stage — no compilation needed).
+**Alternatives considered**: Separate migration image — adds a second image to build and push on every release; unnecessary when the source image already has everything.
+
+## Decision 6: Image tag strategy — placeholder `latest`, substituted at deploy time
+
+**Decision**: Manifests reference image tags using `latest` as a documented placeholder. The operator substitutes the real tag with `kubectl set image` or a `sed` one-liner before applying.
+**Rationale**: Kustomize's `images` transformer is the clean alternative, but introduces a tooling dependency. For a personal single-operator deployment, `sed` or `kubectl set image` after `kubectl apply` is simpler and requires no additional setup. The placeholder is documented in the operator guide (quickstart.md).
+**Alternatives considered**: Kustomize overlays — appropriate for multi-environment setups; over-engineered for one environment.
+
+## Decision 7: Two VaultStaticSecrets (API env and MinIO credentials)
+
+**Decision**: Separate VaultStaticSecret resources for API env vars and MinIO root credentials, syncing into `api-env` and `minio-credentials` K8s Secrets respectively.
+**Rationale**: The API's env secret contains database, JWT, and S3 access credentials. MinIO's root credentials are a different concern with a different rotation lifecycle. Keeping them separate makes Vault policies simpler (least privilege) and avoids giving the API pod access to MinIO's root password.
+**Vault paths assumed**: `reactbin/api/config` (KV v2) for API env; `reactbin/minio/credentials` (KV v2) for MinIO root credentials.
+
+## Decision 8: Namespace manifest included in `k8s/`
+
+**Decision**: `k8s/namespace.yaml` creates the `reactbin` namespace as part of the manifest set.
+**Rationale**: Makes the full deployment self-contained — operator runs `kubectl apply -f k8s/` without a prerequisite namespace creation step.
+**Note**: If the namespace already exists, `kubectl apply` is idempotent.

+# Feature Specification: Kubernetes Production Manifests
+
+**Feature Branch**: `013-k8s-manifests`
+**Created**: 2026-05-07
+**Status**: Draft
+**Input**: User description: "Kubernetes manifests for production deployment to k3s: Deployment, Service, and Ingress for the API and UI; VaultStaticSecret CRDs to sync secrets from HashiCorp Vault; Alembic init container on the API Deployment for schema migrations. The cluster uses an nginx ingress controller with Let's Encrypt TLS, a shared external Postgres instance, MinIO running in-cluster, and VSO (Vault Secrets Operator) for secret management."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 — Application Reachable in Production (Priority: P1)
+
+As an operator, I can apply the manifests to my k3s cluster and have both the API and UI reachable at the production domain over HTTPS, with all health checks passing.
+
+**Why this priority**: This is the core deployment goal. Nothing else matters if the application is not reachable.
+
+**Independent Test**: Apply the API and UI manifests with a manually-created K8s Secret (bypassing Vault). Confirm the UI loads at the domain root and the API health endpoint returns 200 at `/api/v1/health`. Confirm HTTPS is enforced and HTTP redirects to HTTPS.
+
+**Acceptance Scenarios**:
+
+1. **Given** the manifests are applied to the cluster, **When** a browser navigates to `https://<domain>/`, **Then** the UI loads successfully with a valid TLS certificate.
+2. **Given** the manifests are applied, **When** a request is made to `https://<domain>/api/v1/health`, **Then** a 200 response is returned.
+3. **Given** the API docs flag is disabled, **When** a request is made to `https://<domain>/docs`, **Then** a 404 is returned.
+4. **Given** the API pod is restarted, **When** it comes back up, **Then** it passes readiness checks before receiving traffic.
+5. **Given** a request for an unknown path, **When** it is made to the UI, **Then** the SPA serves the index page (client-side routing is preserved).
+
+---
+
+### User Story 2 — Secrets Sourced from Vault (Priority: P2)
+
+As an operator, no secrets are stored in version-controlled manifest files. All sensitive values are declared in Vault and synced automatically into the cluster as Kubernetes Secrets by the Vault Secrets Operator.
+
+**Why this priority**: Security prerequisite for production. Hardcoded secrets in manifests are a material risk.
+
+**Independent Test**: Run `git grep` for known secret patterns across `k8s/` and confirm zero matches. Confirm VaultStaticSecret CRDs reference a Vault path and that the synced K8s Secret is created and the API pod's environment is populated from it.
+
+**Acceptance Scenarios**:
+
+1. **Given** Vault contains the required secret values at the declared path, **When** VSO is running, **Then** a K8s Secret is created in the cluster namespace with the declared keys.
+2. **Given** the K8s Secret exists, **When** the API pod starts, **Then** its environment variables are populated from that secret.
+3. **Given** a `git grep` for plaintext credentials across `k8s/`, **When** run against the committed manifests, **Then** no plaintext secrets are found.
+
+---
+
+### User Story 3 — Schema Migrations Run Before API Starts (Priority: P3)
+
+As an operator, every time the API is deployed, database migrations run automatically in an init container before the main application container starts. A failed migration prevents the pod from starting, protecting against schema drift.
+
+**Why this priority**: Prevents the API from serving requests against a stale or incompatible schema. Safe deployment ordering is essential for production.
+
+**Independent Test**: Deploy with the init container pointing at a valid database. Confirm migrations run and the API starts. Simulate a failing migration by pointing the init container at an unreachable database and confirm the pod stays in init state and does not serve traffic.
+
+**Acceptance Scenarios**:
+
+1. **Given** the API Deployment is applied, **When** the pod starts, **Then** the init container completes `alembic upgrade head` before the main container starts.
+2. **Given** the schema is already current, **When** the pod starts, **Then** the migration init container exits successfully with no changes applied.
+3. **Given** the migration fails, **When** the pod starts, **Then** the init container exits non-zero, the main container does not start, and the pod enters a visible error state.
+
+---
+
+### User Story 4 — MinIO Runs In-Cluster with Persistent Storage (Priority: P4)
+
+As an operator, MinIO runs inside the cluster with a PersistentVolumeClaim for durable storage, is not externally reachable, and has the required bucket initialised on first deployment.
+
+**Why this priority**: Required for image storage, but decoupled from the other manifests — the S3 endpoint is just a config value the API reads.
+
+**Independent Test**: Confirm the MinIO pod is running and has no external Ingress. Confirm the required bucket exists. Restart the MinIO pod and confirm previously stored objects are still accessible.
+
+**Acceptance Scenarios**:
+
+1. **Given** the MinIO manifests are applied, **When** the MinIO pod starts, **Then** the required bucket is created and the API can store and retrieve images.
+2. **Given** the MinIO pod is restarted, **When** it comes back up, **Then** all previously stored objects remain accessible (PVC-backed storage persists).
+3. **Given** no Ingress is defined for MinIO, **When** a connection is attempted from outside the cluster, **Then** MinIO is not reachable.
+
+---
+
+### Edge Cases
+
+- What if Vault is unavailable when VSO tries to sync? VSO retries on a configurable interval; the pod will not start until the K8s Secret exists.
+- What if the database is unreachable during migration? The init container exits non-zero; the pod does not start and Kubernetes retries with backoff.
+- What if the MinIO PVC runs out of space? MinIO will fail writes; the API will return upload errors. Capacity monitoring is out of scope for this feature.
+- What if migrations and the main container use different image tags? They use the same tag in the same Deployment spec, so they are always in sync.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: All manifests MUST target a single configurable namespace (default: `reactbin`).
+- **FR-002**: The API MUST be deployed as a Deployment with liveness and readiness probes on `/api/v1/health`.
+- **FR-003**: The API Deployment MUST include an init container using the same image that runs database schema migrations before the main container starts.
+- **FR-004**: The API Deployment MUST set `API_DOCS_ENABLED=false`.
+- **FR-005**: The UI MUST be deployed as a Deployment with a liveness probe confirming the nginx process is serving.
+- **FR-006**: A single Ingress MUST route `https://<domain>/api/` to the API Service and all other paths to the UI Service, with TLS termination via a cert-manager Let's Encrypt certificate.
+- **FR-007**: HTTP requests MUST be redirected to HTTPS via the Ingress.
+- **FR-008**: All API secrets MUST be declared in a VaultStaticSecret CRD and synced into a K8s Secret; no secret value MUST appear as plaintext in any manifest file.
+- **FR-009**: The API Deployment MUST source all environment variables from the synced K8s Secret via `envFrom`.
+- **FR-010**: MinIO MUST be deployed as a StatefulSet with a PersistentVolumeClaim using the cluster's default storage class.
+- **FR-011**: A Kubernetes Job MUST create the required S3 bucket in MinIO on first deployment and MUST be idempotent on re-apply.
+- **FR-012**: MinIO MUST have no Ingress; it MUST only be accessible within the cluster via ClusterIP.
+- **FR-013**: All containers MUST run as non-root users.
+- **FR-014**: The API production image MUST include migration files so the init container can run migrations without a separate image.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: The application is accessible at the production domain within 120 seconds of `kubectl apply`.
+- **SC-002**: Schema migrations complete and the API begins serving traffic without manual operator intervention on every deployment.
+- **SC-003**: A `git grep` across `k8s/` finds zero plaintext secret values in committed files.
+- **SC-004**: A simulated migration failure holds the pod in init state and the application never serves traffic.
+- **SC-005**: Restarting the MinIO pod does not result in data loss — previously uploaded images remain accessible.
+
+## Assumptions
+
+- The k3s cluster is running with the nginx ingress controller installed.
+- cert-manager is installed and a `ClusterIssuer` named `letsencrypt-prod` is already configured.
+- The Vault Secrets Operator is installed in the cluster.
+- A HashiCorp Vault instance is accessible from the cluster and the required secret values are stored at the declared Vault path before deployment.
+- A shared external PostgreSQL instance is available; the operator creates a dedicated database and user before deploying.
+- DNS for the production domain is already pointing at the cluster ingress IP.
+- Manifests are stored in a `k8s/` directory at the repository root.
+- The cluster's default storage class supports ReadWriteOnce (sufficient for single-replica MinIO).
+- All Deployments run a single replica (personal tool, no HA requirement).
+- Image tags are managed externally; manifests use a placeholder tag that the operator substitutes at deploy time.
+- The `API_DOCS_ENABLED` flag exists on the API (implemented in feature 012).

+
+**Input**: Design documents from `specs/013-k8s-manifests/`
+**Prerequisites**: plan.md ✅, spec.md ✅, research.md ✅, contracts/operator-deploy.md ✅, quickstart.md ✅
+
+**Tests**: K8s manifests have no unit test framework. Validation is via `yamllint` (format) and `kubectl apply --dry-run=client` (schema). Each phase ends with a validation step. The TDD analogue is: write the validate-k8s Makefile target (Phase 1) before any manifest exists, so it immediately fails — then manifests are written to make it pass.
+
+**Organization**: Phase 1 creates the directory structure and validation target. Phase 2 creates the namespace and Vault CRDs (foundational — required by all user story deployments). Phases 3–6 implement user stories. Phase 7 polishes.

+- [X] T002 Add a `validate-k8s` target to `Makefile` immediately after the existing `verify-ui-prod` target: the target MUST run `yamllint -d relaxed k8s/` then `kubectl apply --dry-run=client -f k8s/`; add `validate-k8s` to the `.PHONY` line; note in a comment that `kubectl apply --dry-run=client` requires a kubeconfig with cluster access — offline validation uses `yamllint` only
+
+---
+
+## Phase 2: Foundational (Namespace + Vault CRDs)
+
+**Goal**: Namespace and Vault secret-sync resources that every other manifest depends on.
+
+**⚠️ CRITICAL**: No user story manifest can be applied until this phase is complete — the namespace must exist before any namespaced resource, and the Vault CRDs must exist before the API or MinIO pods can start.
+
+- [X] T003 Create `k8s/namespace.yaml`: a single `Namespace` resource with `name: reactbin` and no additional labels
+
+- [X] T004 [P] Create `k8s/vault/vault-auth.yaml`: a `VaultAuth` resource (`apiVersion: secrets.hashicorp.com/v1beta1`) with `name: reactbin-auth`, `namespace: reactbin`, `spec.method: kubernetes`, `spec.mount: kubernetes`, `spec.kubernetes.role: reactbin`, `spec.kubernetes.serviceAccount: default`, `spec.kubernetes.audiences: [https://kubernetes.default.svc]`; add a comment noting the operator must create the Vault role and bind it to the `default` SA in the `reactbin` namespace with read access to both secret paths
+
+- [X] T005 [P] Create `k8s/vault/api-secret.yaml`: a `VaultStaticSecret` resource with `name: api-secret`, `namespace: reactbin`, `spec.vaultAuthRef: reactbin-auth`, `spec.mount: secret`, `spec.type: kv-v2`, `spec.path: reactbin/api/config`, `spec.refreshAfter: 1h`, `spec.destination.name: api-env`, `spec.destination.create: true`; add a comment listing all required Vault keys: `DATABASE_URL`, `JWT_SECRET_KEY`, `OWNER_USERNAME`, `OWNER_PASSWORD`, `S3_ENDPOINT_URL`, `S3_BUCKET_NAME`, `S3_ACCESS_KEY_ID`, `S3_SECRET_ACCESS_KEY`, `API_BASE_URL`
+
+- [X] T006 [P] Create `k8s/vault/minio-secret.yaml`: same structure as T005 but `name: minio-secret`, `spec.path: reactbin/minio/credentials`, `spec.destination.name: minio-credentials`; comment listing required Vault keys: `MINIO_ROOT_USER`, `MINIO_ROOT_PASSWORD`
+
+**Checkpoint**: Foundational resources complete. User story implementation can now begin.
+
+---
+
+## Phase 3: User Story 1 — Application Reachable in Production (Priority: P1) 🎯 MVP
+
+**Goal**: API and UI are deployed and reachable at the production domain via HTTPS with TLS from cert-manager.
+
+**Independent Test**: Apply all Phase 2 + Phase 3 manifests. Confirm `kubectl get pods -n reactbin` shows api and ui pods Running. Confirm `curl https://<domain>/api/v1/health` returns 200 and `curl https://<domain>/` returns 200.
+
+- [X] T007 [P] [US1] Create `k8s/api/service.yaml`: `Service`, `name: api`, `namespace: reactbin`, `type: ClusterIP`, `selector: {app: api}`, `ports: [{port: 8000, targetPort: 8000, name: http}]`
+
+- [X] T008 [P] [US1] Create `k8s/ui/service.yaml`: `Service`, `name: ui`, `namespace: reactbin`, `type: ClusterIP`, `selector: {app: ui}`, `ports: [{port: 8080, targetPort: 8080, name: http}]`
+
+- [X] T009 [P] [US1] Create `k8s/ui/deployment.yaml`: `Deployment`, `name: ui`, `namespace: reactbin`, 1 replica, `selector.matchLabels: {app: ui}`; container `name: ui`, `image: reactbin-ui:latest` (placeholder — operator substitutes real tag), `ports: [{containerPort: 8080}]`; `livenessProbe: {httpGet: {path: /, port: 8080}, initialDelaySeconds: 10, periodSeconds: 30}`; `securityContext: {runAsNonRoot: true, runAsUser: 101}` (UID 101 is the nginxinc/nginx-unprivileged user); add comment: `# Replace 'latest' with the real image tag before applying`
+
+- [X] T010 [US1] Create `k8s/api/deployment.yaml`: `Deployment`, `name: api`, `namespace: reactbin`, 1 replica, `selector.matchLabels: {app: api}`; container `name: api`, `image: reactbin-api:latest` (placeholder), `ports: [{containerPort: 8000}]`; `envFrom: [{secretRef: {name: api-env}}]`; `env: [{name: API_DOCS_ENABLED, value: "false"}]`; `livenessProbe: {httpGet: {path: /api/v1/health, port: 8000}, initialDelaySeconds: 10, periodSeconds: 30}`; `readinessProbe: {httpGet: {path: /api/v1/health, port: 8000}, initialDelaySeconds: 5, periodSeconds: 10}`; `securityContext: {runAsNonRoot: true, runAsUser: 1001}`; add comment: `# initContainers block added in US3 (T015)`; add comment: `# Replace 'latest' with the real image tag before applying`
+
+- [X] T011 [US1] Create `k8s/ingress.yaml`: `Ingress`, `name: reactbin`, `namespace: reactbin`; `annotations: {"cert-manager.io/cluster-issuer": "letsencrypt-prod", "nginx.ingress.kubernetes.io/ssl-redirect": "true"}`; `spec.ingressClassName: nginx`; `spec.tls: [{hosts: ["<your-domain>"], secretName: reactbin-tls}]`; `spec.rules: [{host: "<your-domain>", http: {paths: [{path: /api/, pathType: Prefix, backend: {service: {name: api, port: {number: 8000}}}}, {path: /, pathType: Prefix, backend: {service: {name: ui, port: {number: 8080}}}}]}}]`; IMPORTANT — `/api/` path entry MUST appear before `/` in the YAML (nginx evaluates in declaration order); add comment: `# Replace <your-domain> with the real domain before applying`
+
+- [X] T012 [US1] Verify US1: run `yamllint -d relaxed k8s/` from the repository root and confirm no errors; run `kubectl apply --dry-run=client -f k8s/` (requires cluster kubeconfig) and confirm all resources in namespace.yaml, vault/, api/, ui/, and ingress.yaml are accepted; if no cluster is available, yamllint passing is sufficient for this checkpoint
+
+**Checkpoint**: US1 complete. API and UI manifests are schema-valid and ready to apply.
+
+---
+
+## Phase 4: User Story 2 — Secrets Sourced from Vault (Priority: P2)
+
+**Goal**: Confirm that no plaintext secret values appear in any committed manifest file. The implementation (VaultAuth + VaultStaticSecret × 2) was completed in Phase 2.
+
+**Independent Test**: `git grep` across `k8s/` finds no plaintext credential values.
+
+- [X] T013 [US2] Verify US2: run `git grep -rn "password\|secret_key\|access_key\|DATABASE_URL" k8s/` and confirm that only key names (in comments) and Vault path references appear — no actual values; also confirm that `k8s/vault/api-secret.yaml` and `k8s/vault/minio-secret.yaml` reference Vault paths under `spec.path` and that `spec.destination.create: true` is set so VSO creates the K8s Secrets
+
+**Checkpoint**: US2 complete. Zero plaintext secrets in manifests; all secrets flow through Vault.
+
+---
+
+## Phase 5: User Story 3 — Schema Migrations Run Before API Starts (Priority: P3)
+
+**Goal**: The API Deployment includes an Alembic init container. `api/Dockerfile.prod` is updated to include migration files.
+
+**Independent Test**: `docker build -f api/Dockerfile.prod api/ -t reactbin-api-prod:test` succeeds and `docker run --rm reactbin-api-prod:test ls /app/alembic` shows migration files. `make validate-k8s` confirms the init container spec is accepted by the Kubernetes schema.
+
+- [X] T014 [US3] Update `api/Dockerfile.prod`: in the **runtime stage** (the `FROM python:3.12-slim` stage), after the line `COPY --chown=appuser:appgroup app/ ./app/`, add two new lines: `COPY --chown=appuser:appgroup alembic/ ./alembic/` and `COPY --chown=appuser:appgroup alembic.ini .`; the builder stage is unchanged; verify with `docker build -f api/Dockerfile.prod api/ -t reactbin-api-prod:test && docker run --rm reactbin-api-prod:test ls /app/alembic /app/alembic.ini`
+
+- [X] T015 [US3] Update `k8s/api/deployment.yaml`: add an `initContainers` block to the pod spec (before the `containers` block) containing one init container: `name: alembic-migrate`, `image: reactbin-api:latest` (same placeholder tag as the main container), `command: ["alembic", "upgrade", "head"]`, `workingDir: /app`, `envFrom: [{secretRef: {name: api-env}}]`, `securityContext: {runAsNonRoot: true, runAsUser: 1001}`; remove the `# initContainers block added in US3 (T015)` comment added in T010
+
+- [X] T016 [US3] Verify US3: run `make validate-k8s` (or `yamllint -d relaxed k8s/`) and confirm the updated deployment.yaml with the init container passes validation; run `docker build -f api/Dockerfile.prod api/ -t reactbin-api-prod:test` and confirm it succeeds; run `docker run --rm reactbin-api-prod:test ls /app/alembic.ini` and confirm the file is present
+
+**Checkpoint**: US3 complete. API Deployment includes Alembic init container; production image includes migration files.
+
+---
+
+## Phase 6: User Story 4 — MinIO In-Cluster with Persistent Storage (Priority: P4)
+
+**Goal**: MinIO runs as a StatefulSet with a PVC, is accessible only within the cluster, and has the required bucket created by a Job.
+
+**Independent Test**: `make validate-k8s` confirms all MinIO manifests pass schema validation. On a live cluster: MinIO pod reaches Running state, bucket exists, no external Ingress for MinIO.
+
+- [X] T017 [P] [US4] Create `k8s/minio/service.yaml`: `Service`, `name: minio`, `namespace: reactbin`, `type: ClusterIP`, `selector: {app: minio}`, `ports: [{port: 9000, targetPort: 9000, name: s3}]`; add comment: `# No Ingress for MinIO — internal access only (FR-012)`
+
+- [X] T018 [US4] Create `k8s/minio/statefulset.yaml`: `StatefulSet` (NOT Deployment — StatefulSet ensures stable PVC binding on pod recreation), `name: minio`, `namespace: reactbin`, `replicas: 1`, `selector.matchLabels: {app: minio}`, `serviceName: minio`; pod `securityContext: {runAsUser: 1000, runAsGroup: 1000, fsGroup: 1000}`; container `name: minio`, `image: minio/minio:latest`, `args: ["server", "/data", "--console-address", ":9001"]`, `ports: [{containerPort: 9000, name: s3}]`; `env: [{name: MINIO_ROOT_USER, valueFrom: {secretKeyRef: {name: minio-credentials, key: MINIO_ROOT_USER}}}, {name: MINIO_ROOT_PASSWORD, valueFrom: {secretKeyRef: {name: minio-credentials, key: MINIO_ROOT_PASSWORD}}}]`; `livenessProbe: {httpGet: {path: /minio/health/live, port: 9000}, initialDelaySeconds: 30, periodSeconds: 20}`; `readinessProbe: {httpGet: {path: /minio/health/ready, port: 9000}, initialDelaySeconds: 15, periodSeconds: 10}`; `volumeMounts: [{name: minio-data, mountPath: /data}]`; `volumeClaimTemplates: [{metadata: {name: minio-data}, spec: {accessModes: [ReadWriteOnce], resources: {requests: {storage: 10Gi}}}}]`; add comment: `# storageClassName omitted — uses cluster default; override if needed`
+
+- [X] T019 [US4] Create `k8s/minio/init-job.yaml`: `Job`, `name: minio-init-bucket`, `namespace: reactbin`; `spec.template.spec.restartPolicy: OnFailure`; container `name: mc`, `image: minio/mc:latest`, `command: ["sh", "-c"]`, `args: ["mc alias set local http://minio.reactbin.svc.cluster.local:9000 $MINIO_ROOT_USER $MINIO_ROOT_PASSWORD && mc mb --ignore-existing local/reactbin"]`; `env: [{name: MINIO_ROOT_USER, valueFrom: {secretKeyRef: {name: minio-credentials, key: MINIO_ROOT_USER}}}, {name: MINIO_ROOT_PASSWORD, valueFrom: {secretKeyRef: {name: minio-credentials, key: MINIO_ROOT_PASSWORD}}}]`; `securityContext: {runAsNonRoot: false}` with comment `# minio/mc runs as root by default; FR-013 exception for this one-off init Job`; add comment: `# --ignore-existing makes this Job idempotent — safe to re-apply`
+
+- [X] T020 [US4] Verify US4: run `make validate-k8s` (or `yamllint -d relaxed k8s/`) and confirm all three MinIO manifests (statefulset.yaml, service.yaml, init-job.yaml) pass validation; confirm no Ingress resource references MinIO
+
+**Checkpoint**: All four user stories complete.
+
+---
+
+## Phase 7: Polish & Cross-Cutting Concerns
+
+- [X] T021 [P] Run `yamllint -d relaxed k8s/` from the repository root and fix any YAML formatting violations across all 12 manifest files; confirm output shows no errors
+
+- [X] T022 [P] Add `.yamllint.yml` at the repository root (if not already present) with `extends: relaxed` and `rules: {line-length: {max: 120}}` to keep line length reasonable for verbose K8s YAML
+
+- [X] T023 Run `make build-prod` to confirm `api/Dockerfile.prod` still builds cleanly after the T014 addition; run `docker run --rm reactbin-api-prod:latest ls /app/alembic.ini /app/alembic/` and confirm both are present in the production image
+
+---
+
+## Dependencies & Execution Order
+
+- T001 and T002 can run in parallel (directory creation vs Makefile edit)
+- T003, T004, T005, T006 can run in parallel after T001 (different files, same phase)
+- T007, T008, T009 can run in parallel after Phase 2 completes
+- T010 after T007 (deployment references service name, easier to write with service done) — but they're different files so technically parallel; keep sequential for clarity
+- T011 after T007 and T008 (Ingress references both service names)
+- T012 after T007–T011
+- T013 after Phase 2 (Vault CRDs exist to inspect)
+- T014 and T015 can run in parallel (different files: Dockerfile.prod vs deployment.yaml)
+- T016 after T014 and T015
+- T017, T018, T019 can run in parallel after Phase 2 completes
+- T020 after T017–T019
+- T021, T022, T023 can run in parallel

+5. Deploy MVP
+
+### Incremental Delivery
+
+1. Setup + Foundational → Apply → namespace and Vault sync ready
+2. Add US1 (API + UI + Ingress) → Deploy → application reachable at domain
+3. Add US3 (Alembic init container) → Deploy → migrations run automatically on rollout
+4. Add US4 (MinIO) → Deploy → persistent image storage in-cluster
+5. Polish → clean YAML, confirmed builds

+## Field Descriptions
+
+| Field | Type | Nullable | Notes |
+|-------|------|----------|-------|
+| `id` | string (UUID) | No | Stable image identifier |
+| `hash` | string (hex) | No | SHA-256 of file content; deduplication key |
+| `filename` | string | No | Original upload filename |
+| `mime_type` | string | No | One of: `image/jpeg`, `image/png`, `image/gif`, `image/webp` |
+| `size_bytes` | integer | No | File size in bytes |
+| `width` | integer | No | Image width in pixels |
+| `height` | integer | No | Image height in pixels |
+| `storage_key` | string | No | Object storage key (retained for backward compat) |
+| `thumbnail_key` | string | Yes | Thumbnail object storage key; null if generation failed |
+| `file_url` | string | No | Full URL to fetch the image file — CDN URL in production, API proxy path in local dev |
+| `thumbnail_url` | string | Yes | Full URL to fetch the thumbnail — CDN URL in production, API proxy path in local dev; null if no thumbnail |
+| `created_at` | string (ISO 8601) | No | Upload timestamp |
+| `tags` | string[] | No | Lowercase normalised tag list |
+| `duplicate` | boolean | Yes | Present only on upload responses; true if hash matched an existing image |
+
+## URL Behaviour
+
+| Configuration | `file_url` example | `thumbnail_url` example |
+|---------------|--------------------|------------------------|
+| `S3_PUBLIC_BASE_URL` set | `https://cdn.reactbin.juggalol.com/{storage_key}` | `https://cdn.reactbin.juggalol.com/{thumbnail_key}` |
+| `S3_PUBLIC_BASE_URL` not set | `/api/v1/images/{id}/file` | `/api/v1/images/{id}/thumbnail` |
+
+## UI Contract
+
+The UI MUST use `file_url` and `thumbnail_url` from the response to render images. The UI MUST NOT construct image URLs from `id`, `storage_key`, or `thumbnail_key` directly. The UI MUST treat `thumbnail_url: null` as "no thumbnail available" and fall back to `file_url` for display.

+# Implementation Plan: CDN Image Serving
+
+**Branch**: `014-r2-cdn-serving` | **Date**: 2026-05-08 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `specs/014-r2-cdn-serving/spec.md`
+
+## Summary
+
+Extend the image metadata API response to include `file_url` and `thumbnail_url` fields. When `S3_PUBLIC_BASE_URL` is configured, these fields contain CDN URLs pointing directly to Cloudflare R2. When unconfigured, they fall back to the existing API proxy paths so local development requires no setup changes. The UI is updated to use these response fields instead of constructing proxy URLs client-side. Proxy endpoints are retained unchanged.
+
+## Technical Context
+
+**Language/Version**: Python 3.12 (API), TypeScript strict mode (UI)
+**Primary Dependencies**: FastAPI, SQLAlchemy 2.x async, Angular (latest stable), pydantic-settings
+**Storage**: PostgreSQL (image metadata), S3-compatible object storage (R2 in production, MinIO in dev)
+**Testing**: pytest (unit + integration), Angular component tests
+**Target Platform**: Linux (k3s), local Docker Compose
+**Project Type**: Web service (API) + SPA (UI)
+**Performance Goals**: No additional latency on API responses; image load latency reduced by eliminating API proxy hop in production
+**Constraints**: No breaking changes to existing API response fields; proxy endpoints must remain functional
+**Scale/Scope**: Single-owner app; ~100 existing images migrated to R2 prior to this feature
+
+## Constitution Check
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| §2.1 Strict separation of concerns | PASS | URL construction stays in router layer; storage backend unchanged |
+| §2.3 Storage abstraction | PASS | No changes to `StorageBackend` interface or `S3StorageBackend` |
+| §2.6 No speculative abstraction | PASS | No new interfaces introduced; URL logic is a simple helper |
+| §3.1 API versioning (`/api/v1/`) | PASS | Adding fields to response is non-breaking per §3.1 |
+| §3.2 OpenAPI as contract | PASS | New fields documented in contracts/image-response.md |
+| §5.1 Tests alongside implementation | REQUIRED | Unit tests for URL construction; integration tests for response fields |
+| §7.2 Environment configuration | PASS | `S3_PUBLIC_BASE_URL` via env var; no hardcoded URLs |
+
+No constitution violations. All gates pass.

+.env.example                    # Add: S3_PUBLIC_BASE_URL= (empty = local dev proxy fallback)
+```
+
+## Key Implementation Details
+
+### URL construction logic (`api/app/routers/images.py`)
+
+`_image_to_dict` gains a `cdn_base: str | None` parameter:
+
+```python
+def _image_to_dict(image: Image, *, cdn_base: str | None = None, duplicate: bool | None = None):
+    base = cdn_base.rstrip("/") if cdn_base else None
+    file_url = f"{base}/{image.storage_key}" if base else f"/api/v1/images/{image.id}/file"
+    thumbnail_url = (
+        (f"{base}/{image.thumbnail_key}" if base else f"/api/v1/images/{image.id}/thumbnail")
+        if image.thumbnail_key else None
+    )
+    return {
+        ...,          # existing fields unchanged
+        "file_url": file_url,
+        "thumbnail_url": thumbnail_url,
+    }
+```
+
+Each endpoint calls `get_settings()` once and passes `settings.s3_public_base_url` as `cdn_base`.
+
+### Config addition (`api/app/config.py`)
+
+```python
+s3_public_base_url: str | None = None
+```
+
+No validator needed — `None` is the valid "not configured" state.
+
+### UI changes (`ui/src/app/services/image.service.ts`)
+
+`ImageRecord` gains two new fields:
+```typescript
+file_url: string;
+thumbnail_url: string | null;
+```
+
+`getFileUrl(id)` and `getThumbnailUrl(id)` methods are removed. Components use `image.file_url` and `image.thumbnail_url` directly.
+
+## Phase Breakdown
+
+### Phase 1: API — config + URL construction (US1 foundation)
+- Add `s3_public_base_url` to config
+- Update `_image_to_dict` with `cdn_base` parameter
+- Update all call sites to pass `cdn_base` from settings
+- Unit tests for URL construction (both CDN and fallback paths)
+- Integration tests verifying `file_url`/`thumbnail_url` in all image responses
+
+### Phase 2: UI — consume response URLs (US1 + US2)
+- Update `ImageRecord` interface
+- Remove `getFileUrl`/`getThumbnailUrl` methods from service
+- Update library component
+- Update detail component
+- Update service tests
+
+### Phase 3: Config + docs
+- Add `S3_PUBLIC_BASE_URL` to `.env.example`
+- Manual end-to-end verification (local dev + production)

+# Quickstart: CDN Image Serving
+
+## Local development (no CDN)
+
+No configuration change required. `S3_PUBLIC_BASE_URL` is unset by default.
+
+```bash
+docker compose up
+```
+
+Upload an image and inspect the API response:
+
+```bash
+curl -s http://localhost:8000/api/v1/images | jq '.items[0] | {file_url, thumbnail_url}'
+```
+
+Expected (local dev — relative proxy paths):
+```json
+{
+  "file_url": "/api/v1/images/550e8400-.../file",
+  "thumbnail_url": "/api/v1/images/550e8400-.../thumbnail"
+}
+```
+
+The UI loads images via these relative paths, which hit the API proxy as before.
+
+---
+
+## Production (CDN configured)
+
+Add `S3_PUBLIC_BASE_URL` to the Vault secret bundle at `reactbin/api/config`:
+
+```
+S3_PUBLIC_BASE_URL = https://cdn.reactbin.juggalol.com
+```
+
+Force VSO sync and restart:
+
+```bash
+kubectl annotate vaultstaticsecret api-secret -n reactbin \
+  secrets.hashicorp.com/force-sync=$(date +%s) --overwrite
+
+kubectl rollout restart deployment/api -n reactbin
+```
+
+Upload a test image and inspect the response:
+
+```bash
+curl -s https://reactbin.juggalol.com/api/v1/images | jq '.items[0] | {file_url, thumbnail_url}'
+```
+
+Expected (production — CDN URLs):
+```json
+{
+  "file_url": "https://cdn.reactbin.juggalol.com/e3b0c44...",
+  "thumbnail_url": "https://cdn.reactbin.juggalol.com/e3b0c44....thumb"
+}
+```
+
+Open the browser network panel on the library page and confirm image requests go to `cdn.reactbin.juggalol.com`, not `/api/`.
+
+---
+
+## Verifying existing images after migration
+
+All existing images were migrated to R2 with the same object keys before this feature was deployed. Once `S3_PUBLIC_BASE_URL` is configured, the API will return CDN URLs for all images immediately — no per-image migration step is needed.

+# Research: CDN Image Serving
+
+## Decision 1: Where does URL construction logic live?
+
+**Decision**: In the image router's `_image_to_dict` helper, not in the `StorageBackend`.
+
+**Rationale**: The `StorageBackend` interface is responsible for put/get/delete of object bytes. Adding URL construction there conflates two concerns — storage operations and HTTP URL generation — and would require the storage abstraction to know about CDN configuration. The router already has access to application settings via `get_settings()` and knows the image ID and storage key, making it the natural place to construct URLs.
+
+**Alternatives considered**: Adding a `get_url(key)` method to `StorageBackend` — rejected because it leaks HTTP/CDN concerns into the storage abstraction, violating §2.3.
+
+---
+
+## Decision 2: Fallback URL format in local development
+
+**Decision**: Relative paths (`/api/v1/images/{id}/file`, `/api/v1/images/{id}/thumbnail`) when `S3_PUBLIC_BASE_URL` is not set.
+
+**Rationale**: Relative paths work regardless of the host the app is running on, require no additional configuration, and match how the UI currently constructs these URLs via `getFileUrl(id)` and `getThumbnailUrl(id)`. An absolute fallback would require `API_BASE_URL` to be set in local dev, adding unnecessary setup friction.
+
+**Alternatives considered**: Absolute URL fallback using `API_BASE_URL` — rejected because it adds a mandatory config dependency where none exists today.
+
+---
+
+## Decision 3: Trailing slash normalisation
+
+**Decision**: Strip trailing slash from `S3_PUBLIC_BASE_URL` at construction time using `rstrip('/')` in the config validator or at point of use.
+
+**Rationale**: Prevents double-slash URLs (`https://cdn.example.com//key`) if the operator includes a trailing slash in the configured value. Simple, defensive, zero-cost.
+
+---
+
+## Decision 4: Proxy endpoints retained or removed?
+
+**Decision**: Retained, fully functional, unchanged.
+
+**Rationale**: Spec FR-005 explicitly requires them. They serve as the local dev fallback and a safety net if the CDN is temporarily unavailable or misconfigured. Removing them would break local development immediately.
+
+---
+
+## Decision 5: `storage_key` and `thumbnail_key` in API response
+
+**Decision**: Keep both fields in the response alongside the new `file_url` and `thumbnail_url`.
+
+**Rationale**: Removing them is a breaking API change. The UI currently reads `thumbnail_key` to decide whether a thumbnail exists. After this change the UI will use `thumbnail_url` (null when no thumbnail), but the keys remain in the response for backward compatibility with any tooling.
+
+---
+
+## Decision 6: Settings access in `_image_to_dict`
+
+**Decision**: Pre-compute the CDN base URL string once per request at the endpoint level and pass it into `_image_to_dict` as a parameter, rather than calling `get_settings()` inside the helper.
+
+**Rationale**: Keeps `_image_to_dict` a pure function (easier to test), avoids calling `get_settings()` inside a helper that is called in a loop (image list endpoint), and makes the dependency explicit.

+# Feature Specification: CDN Image Serving
+
+**Feature Branch**: `014-r2-cdn-serving`
+**Created**: 2026-05-08
+**Status**: Draft
+**Input**: User description: "R2 CDN image serving with local dev fallback to API proxy"
+
+## Overview
+
+Images and thumbnails are currently served by proxying bytes through the API. This feature changes image delivery so that clients receive direct URLs pointing to a CDN edge network, eliminating the API as a middleman for image content. In local development, where no CDN is available, the API proxy endpoints remain as a fallback so the developer experience is unchanged.
+
+---
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Images Load Directly from CDN (Priority: P1)
+
+When a visitor views the image library or opens an image detail page, images and thumbnails are fetched directly from the CDN rather than through the application server. The page loads faster because image bytes no longer pass through the API.
+
+**Why this priority**: Core value of the feature. Reduces API load and improves image load speed for all users.
+
+**Independent Test**: Upload an image, open the library page, and inspect the network requests. Image and thumbnail requests should go directly to the CDN domain, not to `/api/`. The API response for the image list should include direct CDN URLs for each image and thumbnail.
+
+**Acceptance Scenarios**:
+
+1. **Given** a published image, **When** the visitor loads the image library, **Then** each thumbnail `src` URL points to the CDN domain and loads without passing through the API
+2. **Given** a published image, **When** the visitor opens the detail page, **Then** the full image `src` URL points to the CDN domain
+3. **Given** the API returns image metadata, **When** the response is inspected, **Then** it includes a `file_url` and `thumbnail_url` field containing full CDN URLs
+
+---
+
+### User Story 2 - Local Development Works Without CDN (Priority: P2)
+
+In local development, where no CDN is configured, images continue to load via the existing API proxy endpoints. No additional setup is required to run the application locally.
+
+**Why this priority**: Developer experience must not regress. The proxy endpoints must remain functional and be used automatically when no CDN is configured.
+
+**Independent Test**: Run the application locally without setting a public base URL. Upload an image. Verify the library and detail pages load images correctly via the API proxy endpoints, with no errors or broken images.
+
+**Acceptance Scenarios**:
+
+1. **Given** no CDN base URL is configured, **When** the API returns image metadata, **Then** `file_url` and `thumbnail_url` point to the API proxy paths (e.g. `/api/v1/images/{id}/file`)
+2. **Given** no CDN base URL is configured, **When** a visitor views the library, **Then** thumbnails load via the API proxy with no broken images
+3. **Given** a CDN base URL is configured, **When** the application starts, **Then** all image URLs use the CDN domain instead of the proxy paths
+
+---
+
+### Edge Cases
+
+- What happens when the CDN base URL is set but the object does not exist in CDN storage? The browser receives a 404 from the CDN — the API does not re-proxy the content.
+- What happens if an image has no thumbnail (thumbnail generation failed)? The `thumbnail_url` field is absent or null; the UI falls back to the full image URL as it does today.
+- What happens if the CDN base URL has a trailing slash? The system normalises the URL to avoid double slashes in constructed paths.
+
+---
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: The API MUST include a `file_url` field in all image metadata responses, containing the full URL from which the image file can be fetched
+- **FR-002**: The API MUST include a `thumbnail_url` field in all image metadata responses when a thumbnail exists, containing the full URL from which the thumbnail can be fetched
+- **FR-003**: When a CDN base URL is configured, `file_url` and `thumbnail_url` MUST point to the CDN domain
+- **FR-004**: When no CDN base URL is configured, `file_url` and `thumbnail_url` MUST point to the existing API proxy endpoints so local development continues to work without additional setup
+- **FR-005**: The existing API proxy endpoints (`/images/{id}/file`, `/images/{id}/thumbnail`) MUST remain functional regardless of whether a CDN base URL is configured
+- **FR-006**: The UI MUST use `file_url` and `thumbnail_url` from the API response to render images, rather than constructing proxy URLs client-side
+- **FR-007**: The CDN base URL MUST be configurable via environment variable; no value is required in local development
+- **FR-008**: A trailing slash in the configured CDN base URL MUST NOT result in double slashes in constructed image URLs
+- **FR-009**: When `thumbnail_url` is null, the UI MUST fall back to `file_url` for thumbnail display rather than rendering a broken image
+
+### Key Entities
+
+- **Image metadata response**: Extended to include `file_url` and `thumbnail_url` fields alongside existing fields (`id`, `filename`, `tags`, `width`, `height`, `mime_type`, etc.)
+
+---
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: In production, zero image or thumbnail requests pass through the API server — all are served directly by the CDN
+- **SC-002**: Local development requires no additional configuration beyond what is already required — `docker compose up` continues to work with images loading correctly
+- **SC-003**: All existing image-related API integration tests continue to pass after the change
+- **SC-004**: Image metadata responses include `file_url` and `thumbnail_url` fields for 100% of images that have been successfully stored
+
+---
+
+## Assumptions
+
+- The CDN storage bucket and public domain are already configured and operational before this feature is deployed — this feature only changes how URLs are constructed and served, not how objects are stored
+- Object keys in CDN storage are identical to those used in the existing storage backend — no key remapping is needed
+- The CDN serves objects publicly without authentication — no signed URL generation is required
+- The existing API proxy endpoints are retained as functional fallbacks; the UI stops calling them in production but they are not removed
+- Local development uses the existing MinIO-backed proxy and does not require a locally running CDN

+# Tasks: CDN Image Serving
+
+**Input**: Design documents from `specs/014-r2-cdn-serving/`
+**Prerequisites**: plan.md ✅, spec.md ✅, research.md ✅, contracts/image-response.md ✅, quickstart.md ✅
+
+**Tests**: Unit tests for URL construction logic; integration tests asserting `file_url` and `thumbnail_url` in all image responses. Tests accompany each implementation task per §5.1.
+
+**Organization**: Phase 1 adds the config value (foundational — blocks everything). Phase 2 implements US1 (CDN URL serving in API + UI consumption). Phase 3 verifies US2 (local dev fallback). Polish runs the full suite and manual end-to-end check.
+
+## Format: `[ID] [P?] [Story] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to
+
+---
+
+## Phase 1: Foundational (Config)
+
+**Goal**: Add `s3_public_base_url` to config and `.env.example`. All US1 and US2 tasks depend on this.
+
+**⚠️ CRITICAL**: No user story work can begin until this phase is complete.
+
+- [X] T001 Add `s3_public_base_url: str | None = None` to the `Settings` class in `api/app/config.py` (after `api_base_url`); add `S3_PUBLIC_BASE_URL=` with comment "# CDN base URL for serving images (e.g. https://cdn.example.com). Leave empty in local dev to use API proxy fallback." to `.env.example` after the `API_BASE_URL` line
+
+**Checkpoint**: Config in place — user story work can begin.
+
+---
+
+## Phase 2: User Story 1 — Images Load Directly from CDN (Priority: P1) 🎯 MVP
+
+**Goal**: API returns `file_url` and `thumbnail_url` in all image responses; UI uses those fields to render images rather than constructing proxy URLs client-side.
+
+**Independent Test**: With `S3_PUBLIC_BASE_URL=https://cdn.reactbin.juggalol.com` set, call `GET /api/v1/images` and confirm each item has `file_url` starting with `https://cdn.reactbin.juggalol.com/` and `thumbnail_url` starting with `https://cdn.reactbin.juggalol.com/` (or null). Open the library page in a browser and confirm image requests go to the CDN domain in the network panel.
+
+- [X] T002 [US1] Write unit tests in `api/tests/unit/test_url_construction.py` covering four cases: (1) CDN base set, image has thumbnail — `file_url` and `thumbnail_url` are CDN URLs; (2) CDN base set, image has no thumbnail — `thumbnail_url` is None; (3) CDN base not set, image has thumbnail — `file_url` is `/api/v1/images/{id}/file` and `thumbnail_url` is `/api/v1/images/{id}/thumbnail`; (4) CDN base not set, no thumbnail — `thumbnail_url` is None. Test the trailing-slash normalisation case (CDN base with trailing slash produces no double-slash). Import and call `_image_to_dict` directly with a mock `Image` object.
+
+- [X] T003 [US1] Update `_image_to_dict` in `api/app/routers/images.py`: add `cdn_base: str | None = None` keyword parameter; compute `_base = cdn_base.rstrip("/") if cdn_base else None`; set `file_url = f"{_base}/{image.storage_key}" if _base else f"/api/v1/images/{image.id}/file"`; set `thumbnail_url = (f"{_base}/{image.thumbnail_key}" if _base else f"/api/v1/images/{image.id}/thumbnail") if image.thumbnail_key else None`; add `"file_url": file_url` and `"thumbnail_url": thumbnail_url` to the returned dict. Run `make test-unit` and confirm T002 tests pass.
+
+- [X] T004 [US1] Update every `_image_to_dict(...)` call site in `api/app/routers/images.py`: at the top of each endpoint function that calls `_image_to_dict`, add `_cdn_base = get_settings().s3_public_base_url` (import `get_settings` is already present); pass `cdn_base=_cdn_base` to every `_image_to_dict` call in that endpoint. Affected endpoints: `upload_image`, `list_images`, `get_image`, `patch_image_tags`. Confirm `get_settings()` is called once per endpoint, not once per image in a loop (for `list_images`, call it before the list comprehension).
+
+- [X] T005 [US1] Update integration tests: in `api/tests/integration/test_upload.py`, add assertions after existing response checks that `"file_url"` is present in the response body and starts with `/api/v1/images/` (since no CDN is configured in test env); add the same assertion for `"thumbnail_url"` in `test_upload_returns_thumbnail_key`; add assertion that `thumbnail_url` is None in the test that expects `thumbnail_key` to be None. Run `make test-integration` and confirm all pass.
+
+- [X] T006 [P] [US1] Update `ui/src/app/services/image.service.ts`: add `file_url: string` and `thumbnail_url: string | null` to the `ImageRecord` interface; remove the `getFileUrl(id: string): string` method; remove the `getThumbnailUrl(id: string): string` method.
+
+- [X] T007 [P] [US1] Update `ui/src/app/library/library.component.ts`: replace `[src]="imageService.getThumbnailUrl(img.id)"` (line 77) with `[src]="img.thumbnail_url ?? img.file_url"` — fall back to `file_url` when thumbnail is absent (FR-009); update `ui/src/app/library/library.component.spec.ts` to add `file_url` and `thumbnail_url` to any mock `ImageRecord` objects and remove any references to `getThumbnailUrl()`.
+
+- [X] T008 [P] [US1] Update `ui/src/app/detail/detail.component.ts`: replace `[src]="imageService.getFileUrl(image.id)"` (line 52) with `[src]="image.file_url"`; update `ui/src/app/detail/detail.component.spec.ts` to add `file_url` and `thumbnail_url` to any mock `ImageRecord` objects and remove any references to `getFileUrl()`.
+
+- [X] T009 [US1] Update `ui/src/app/services/image.service.spec.ts`: add `file_url` and `thumbnail_url` fields to any mock `ImageRecord` objects used in tests; remove any test cases that test `getFileUrl()` or `getThumbnailUrl()` (these methods no longer exist). Run UI tests and confirm they pass.
+
+**Checkpoint**: US1 complete. API returns CDN URLs when configured; UI uses response fields to render images.
+
+---
+
+## Phase 3: User Story 2 — Local Development Works Without CDN (Priority: P2)
+
+**Goal**: Confirm that with no `S3_PUBLIC_BASE_URL` configured, `file_url` and `thumbnail_url` fall back to API proxy paths and images load correctly in local dev.
+
+**Independent Test**: Run `make test-unit && make test-integration` with no `S3_PUBLIC_BASE_URL` set (the default). Confirm all tests pass and that `file_url` values in integration test responses begin with `/api/v1/images/`.
+
+- [X] T010 [US2] Verify US2: run `make test-unit` and confirm the url-construction unit tests for the "no CDN base" case (T002 cases 3 and 4) pass; run `make test-integration` and confirm the updated upload tests (T005) pass — they already assert relative proxy paths since the test environment has no `S3_PUBLIC_BASE_URL`. Confirm `docker compose up` starts cleanly and images load in the browser via the proxy paths with no console errors.
+
+**Checkpoint**: US2 verified. Local development requires no additional configuration.
+
+---
+
+## Phase 4: Polish & Cross-Cutting Concerns
+
+- [X] T011 [P] Run `ruff check api/app/routers/images.py api/app/config.py` and fix any lint issues; run `ruff format --check` and format if needed.
+
+- [X] T012 Run end-to-end verification per `specs/014-r2-cdn-serving/quickstart.md`: in production with `S3_PUBLIC_BASE_URL` set, call `GET /api/v1/images` and confirm `file_url` and `thumbnail_url` begin with `https://cdn.reactbin.juggalol.com/`; open the library page in a browser and confirm image requests in the network panel go to `cdn.reactbin.juggalol.com`, not `/api/`.
+
+---
+
+## Dependencies & Execution Order
+
+- T001 must complete before any other task
+- T002 before T003 (tests before implementation — unit test first)
+- T003 before T004 (update helper before call sites)
+- T004 before T005 (implementation before integration tests)
+- T006, T007, T008 can run in parallel after T001 (different files)
+- T009 after T006 (spec depends on updated interface)
+- T010 after T003–T009 (verification requires full implementation)
+- T011 after T003–T004 (lint the changed files)
+- T012 last (manual end-to-end)
+
+### Execution Order Summary
+
+```
+Step 1: T001                          (foundational: config)
+Step 2: T002                          (US1: unit tests first)
+Step 3: T003                          (US1: implement _image_to_dict)
+Step 4: T004 ∥ T006 ∥ T007 ∥ T008    (US1: call sites + UI in parallel)
+Step 5: T005 ∥ T009                   (US1: integration tests + service spec)
+Step 6: T010                          (US2: verify local dev fallback)
+Step 7: T011                          (polish: lint)
+Step 8: T012                          (polish: manual end-to-end)

+## Implementation Strategy
+
+### MVP (US1 only — CDN URLs in API + UI)
+
+1. T001 — config
+2. T002–T005 — API implementation and tests
+3. T006–T009 — UI updates
+4. **STOP and VALIDATE**: `make test-unit && make test-integration`, check browser network panel
+
+### Incremental Delivery
+
+1. T001–T005 (API only) → deploy → verify CDN URLs appear in API responses
+2. T006–T009 (UI) → deploy → verify browser fetches images from CDN
+3. T010 (local dev verification) → confirm fallback intact
+4. T011–T012 (polish + end-to-end) → ship
