# Conformance Milestone vi — Feature migrations

**Goal:** Backfill manifests + self-asserting `bind-production` for the remaining four features (`blog`, `media`, `navigation`, `marketing-pages`). After this milestone, every feature is conformance-compliant; `feature-must-have-manifest` flips from WARN to ERROR.

**Architecture:** For each feature: create `src/feature.manifest.ts` declaring its use cases (with `mutates: true` for state-changing ops like createArticle / deleteMedia; rest read-only; all with empty audits/publishes/consumes — none of the current use-case bodies have literal-string `bus.publish(...)` or `auditLog.record({type: "..."})` calls, so empty arrays are correct). Re-export from feature `index.ts`. Update each `bind-production.ts` to import `assertFeatureConformance` + `<name>Manifest` and call the assertion at the tail with the appropriate symbol map.

**Inventory:**
- `blog` — useCases: `getArticles` (read), `createArticle` (mutate), `getArticleBySlug` (read)
- `media` — useCases: `getMedia` (read), `listMedia` (read), `deleteMedia` (mutate)
- `navigation` — useCases: `getHeader` (read)
- `marketing-pages` — useCases: `getPageBySlug` (read), `getSiteSettings` (read)

## Tasks

### Task 1: Story 06 scaffold

Create `docs/work/conformance-system-v1/06-feature-migrations/_story.md`:

```markdown
---
id: 06-feature-migrations
epic: conformance-system-v1
title: Migrate blog/media/navigation/marketing-pages to conformance pattern
type: technical-story
status: in-progress
feature: <cross-feature>
depends-on: [05-generator-updates]
blocks: []
---

## Goal
Every feature in the repo has a manifest + a self-asserting bindProduction.
After this milestone, `feature-must-have-manifest` flips from WARN to ERROR.

## Why
Three of the four enforcement layers already exist; the only thing keeping
them from being fully effective is that 4 of 5 features still don't have
manifests. This story closes that gap.

## In scope
- `feature.manifest.ts` for blog / media / navigation / marketing-pages
- Manifest re-export from each feature's `src/index.ts`
- `bind-production.ts` update for each: imports + tail `assertFeatureConformance` call
- Flip `feature-must-have-manifest` from `warn` to `error` in base.js

## Out of scope
- Adding publishes/audits to existing use cases (declared empty for now — the
  existing `auth.signUp` `bus.publish(userSignedUpEvent, ...)` uses a non-literal
  event name so the rule doesn't fire; other features have no publish/record calls)
- Cross-feature event wiring (blog→marketing welcome flows, etc.)
- Migrating realtime channels or jobs into manifests

## Tasks
- [ ] Story scaffold
- [ ] blog manifest + binding + re-export
- [ ] media manifest + binding + re-export
- [ ] navigation manifest + binding + re-export
- [ ] marketing-pages manifest + binding + re-export
- [ ] Flip feature-must-have-manifest to error
- [ ] Final verification + closeout
```

### Task 2: Migrate blog

Create `packages/blog/src/feature.manifest.ts`:

```ts
import { defineFeature } from "@repo/core-shared/conformance";

/**
 * The blog feature's conformance manifest.
 */
export const blogManifest = defineFeature({
  name: "blog",
  requiredCores: [],
  useCases: {
    getArticles: {
      mutates: false,
      audits: [],
      publishes: [],
      consumes: [],
    },
    getArticleBySlug: {
      mutates: false,
      audits: [],
      publishes: [],
      consumes: [],
    },
    createArticle: {
      mutates: true,
      audits: [],
      publishes: [],
      consumes: [],
    },
  },
  realtimeChannels: [],
  jobs: [],
} as const);

export type BlogManifest = typeof blogManifest;
```

Re-export from `packages/blog/src/index.ts` — append at the bottom:

```ts
export { blogManifest, type BlogManifest } from "./feature.manifest";
```

Update `packages/blog/src/di/bind-production.ts`. Read the file. Add these two imports near the existing imports:

```ts
import { assertFeatureConformance } from "@repo/core-shared/conformance";
import { blogManifest } from "../feature.manifest";
```

At the end of the `bindProductionBlog(ctx)` function body — after the existing `// <gen:*>` anchors, before the closing `}` — add:

```ts
  // Boot-time conformance check.
  assertFeatureConformance(
    blogContainer,
    blogManifest,
    {
      getArticles: BLOG_SYMBOLS.IGetArticlesUseCase,
      getArticleBySlug: BLOG_SYMBOLS.IGetArticleBySlugUseCase,
      createArticle: BLOG_SYMBOLS.ICreateArticleUseCase,
    },
    ctx,
  );
```

(The container variable name might be `blogContainer` — verify by reading the existing file; if it's named differently, use the actual name.)

Verify:
```
pnpm --filter @repo/blog typecheck
pnpm --filter @repo/blog test
```

Commit:
```bash
git add packages/blog/src/feature.manifest.ts packages/blog/src/index.ts packages/blog/src/di/bind-production.ts
git commit -m "feat(blog): conformance manifest + self-asserting bind-production"
```

### Task 3: Migrate media

Same shape. Create `packages/media/src/feature.manifest.ts`:

```ts
import { defineFeature } from "@repo/core-shared/conformance";

export const mediaManifest = defineFeature({
  name: "media",
  requiredCores: [],
  useCases: {
    getMedia: { mutates: false, audits: [], publishes: [], consumes: [] },
    listMedia: { mutates: false, audits: [], publishes: [], consumes: [] },
    deleteMedia: { mutates: true, audits: [], publishes: [], consumes: [] },
  },
  realtimeChannels: [],
  jobs: [],
} as const);

export type MediaManifest = typeof mediaManifest;
```

Append to `packages/media/src/index.ts`:
```ts
export { mediaManifest, type MediaManifest } from "./feature.manifest";
```

Update `packages/media/src/di/bind-production.ts` — add imports and tail call:

```ts
import { assertFeatureConformance } from "@repo/core-shared/conformance";
import { mediaManifest } from "../feature.manifest";
```

End of function body:
```ts
  assertFeatureConformance(
    mediaContainer,
    mediaManifest,
    {
      getMedia: MEDIA_SYMBOLS.IGetMediaUseCase,
      listMedia: MEDIA_SYMBOLS.IListMediaUseCase,
      deleteMedia: MEDIA_SYMBOLS.IDeleteMediaUseCase,
    },
    ctx,
  );
```

Verify + commit:
```bash
pnpm --filter @repo/media typecheck && pnpm --filter @repo/media test
git add packages/media/src/feature.manifest.ts packages/media/src/index.ts packages/media/src/di/bind-production.ts
git commit -m "feat(media): conformance manifest + self-asserting bind-production"
```

### Task 4: Migrate navigation

`packages/navigation/src/feature.manifest.ts`:

```ts
import { defineFeature } from "@repo/core-shared/conformance";

export const navigationManifest = defineFeature({
  name: "navigation",
  requiredCores: [],
  useCases: {
    getHeader: { mutates: false, audits: [], publishes: [], consumes: [] },
  },
  realtimeChannels: [],
  jobs: [],
} as const);

export type NavigationManifest = typeof navigationManifest;
```

Append to `packages/navigation/src/index.ts`:
```ts
export { navigationManifest, type NavigationManifest } from "./feature.manifest";
```

Update `packages/navigation/src/di/bind-production.ts`. Imports:
```ts
import { assertFeatureConformance } from "@repo/core-shared/conformance";
import { navigationManifest } from "../feature.manifest";
```

Tail of function:
```ts
  assertFeatureConformance(
    navigationContainer,
    navigationManifest,
    { getHeader: NAVIGATION_SYMBOLS.IGetHeaderUseCase },
    ctx,
  );
```

Verify + commit.

### Task 5: Migrate marketing-pages

`packages/marketing-pages/src/feature.manifest.ts`:

```ts
import { defineFeature } from "@repo/core-shared/conformance";

export const marketingPagesManifest = defineFeature({
  name: "marketing-pages",
  requiredCores: [],
  useCases: {
    getPageBySlug: { mutates: false, audits: [], publishes: [], consumes: [] },
    getSiteSettings: { mutates: false, audits: [], publishes: [], consumes: [] },
  },
  realtimeChannels: [],
  jobs: [],
} as const);

export type MarketingPagesManifest = typeof marketingPagesManifest;
```

Append to `packages/marketing-pages/src/index.ts`:
```ts
export { marketingPagesManifest, type MarketingPagesManifest } from "./feature.manifest";
```

Update `packages/marketing-pages/src/di/bind-production.ts`:
```ts
import { assertFeatureConformance } from "@repo/core-shared/conformance";
import { marketingPagesManifest } from "../feature.manifest";
```

Tail:
```ts
  assertFeatureConformance(
    marketingPagesContainer,
    marketingPagesManifest,
    {
      getPageBySlug: MARKETING_PAGES_SYMBOLS.IGetPageBySlugUseCase,
      getSiteSettings: MARKETING_PAGES_SYMBOLS.IGetSiteSettingsUseCase,
    },
    ctx,
  );
```

Note: `MARKETING_PAGES_SYMBOLS` might be a different name in this package — verify by reading the existing `symbols.ts` first and use the actual exported constant name.

Verify + commit.

### Task 6: Flip `feature-must-have-manifest` from WARN to ERROR

Now that all features have manifests, the rule should hard-fail.

Modify `packages/core-eslint/base.js`. Find:

```js
"conformance/feature-must-have-manifest": [
  "warn",
  { repoRoot },
],
```

Change `"warn"` to `"error"`. Other rule severities stay as they are.

Run `pnpm lint` to verify still passes (now 0 warnings from feature-must-have-manifest because all features have manifests).

Commit:
```bash
git add packages/core-eslint/base.js
git commit -m "feat(core-eslint): flip feature-must-have-manifest from warn to error"
```

### Task 7: Final verification + closeout

```
pnpm typecheck
pnpm test
pnpm lint
pnpm conformance
pnpm turbo boundaries
```

All pass.

Update `docs/work/conformance-system-v1/06-feature-migrations/_story.md`:
- frontmatter `status: in-progress` → `done`
- All `- [ ]` → `- [x]`

Update `docs/work/conformance-system-v1/_epic.md`. Find:
```markdown
- [ ] 07 — Migrate auth feature reference (later plan)
```

Replace with:
```markdown
- [x] [06 — Migrate blog / media / navigation / marketing-pages](06-feature-migrations/_story.md)
- [x] 07 — Migrate auth feature reference (completed inline in milestone i; signIn through ProductionUseCase slot)
```

Also: since this completes the conformance-system-v1 epic's planned stories, flip the epic frontmatter `status: in-progress` → `status: done`.

Commit: `docs(work): close story 06 + conformance-system-v1 epic`.
