Mark 64daf49638 feat(showcase/mastra): v1 bridge alpha + reasoning/streaming out of not_supported (OSS-381) (#5798)
## Mastra Partner Refresh — showcase finalization (OSS-381)

Bumps the showcase Mastra integration onto the **v1 bridge alpha** and
flips the
features it unblocks out of `not_supported`. Opened for CI to run the
D6/e2e
suite (local Docker daemon is wedged in the authoring env — see notes).

### Landed
- **OSS-382 (gate):** `@ag-ui/mastra` `0.2.1-beta.2` →
**`1.1.0-alpha.0`**.
- Alpha verified to ship all features (grep on dist):
`emitInterruptOutcome`,
`STATE_DELTA`, `observationalMemory`, `background-task`,
`tracingOptions`,
`getA2UITools`/recovery. Peers satisfied (`@mastra/core` 1.41,
`client-js`
    1.23.2, runtime 1.61.2).
- `next build` passes (40 routes). Unit tests **identical to the beta.2
baseline** (13 pre-existing failures in `route.test.ts`'s error-path
mocks,
    unrelated to the bump — proven by a stash+reinstall A/B).
- **OSS-384 / OSS-423:** moved into `features` (demos + e2e + aimock
fixtures
  were already wired, gated on this release):
  `agentic-chat-reasoning`, `reasoning-default-render`,
`tool-rendering-reasoning-chain`, `shared-state-streaming`. Added the
missing
  `reasoning-default` / `reasoning-custom` manifest demo entries.
- **Parity:** `not_supported_features` now holds only `gen-ui-interrupt`
+
`interrupt-headless`, matching the **langgraph-python gold standard**,
which
quarantines the same two cells on an upstream `@copilotkit/react-core`
v2
  resume-path hook bug (published-package fix, out of scope). The native
interrupt + RUN_FINISHED-outcome path ships in the bridge; the showcase
cell
  is blocked by the same upstream bug, not the bridge.
- **OSS-424:** execution-tracing note (`tracingOptions` in / `traceId`
on
  `RUN_FINISHED.result` out) added to the Mastra Copilot Runtime doc.
- **OSS-425:** GenUI `generative_ui` spectrum already at parity with
gold
  (`constrained-explicit`, `a2ui-fixed-schema`, `a2ui-dynamic-schema`).

### Not in this PR (scoped, blocked, or pending)
- **OSS-422 a2ui-recovery**, **OSS-426 background-agents**, **OSS-427
observational-memory** — new demo cells. Reference material + build
plans
  ready. OM additionally needs `@mastra/memory` ≥1.21.2 (repo pins
`1.0.1-alpha.1`; the on-stream async-buffering path won't fire below
that).
- **OSS-91 browser-use** — Mastra-only, non-deterministic (no clean
aimock
  replay), needs a Browserbase key not present in the env. Blocked.
- **OSS-392 input.context** — owner exception; only if langgraph
showcases it.

### Verification note
Local D6 could not be run: the Docker daemon's container-creation path
is wedged
in this environment (a trivial `hello-world` create hangs), and
unwedging needs a
Docker Desktop restart that would destroy a concurrent session's running
stack.
Relying on CI for D6/e2e. Everything above is build-level verified +
committed.

Shell Docs

showcase/shell-docs is the Next.js app that builds and serves docs.copilotkit.ai. Author CopilotKit product documentation here, not in the retired top-level docs/ app.

Run Locally

Shell-docs is a standalone npm-based app. You do not need a root install just to run the docs app locally.

cd showcase/scripts
npm install

cd ../shell-docs
npm install
npm run dev

The local dev server runs on port 3003.

http://localhost:3003

The shell-docs npm lifecycle generates registry, demo-content, setup-content, and search data before dev, build, and typecheck.

Validate Changes

Run these from showcase/shell-docs:

npm run build
npm run typecheck
npm run test

For repo-level CI parity, prefer Nx when a shell-docs target is available in the current checkout and root dependencies are installed. For normal shell-docs local development, the npm commands above are the canonical path.

Authoring Recipes

Showcase-Driven Framework Docs

Showcase-driven frameworks use docs_mode: generated. The docs are assembled from showcase registry/generated data, demos, source regions, shared/root MDX, snippets, and sparse framework overrides.

To update showcase-driven docs:

  1. Edit the showcase source of truth: manifests, demos, feature coverage, source regions, or registry inputs.
  2. Edit shared/root MDX only when the change applies across generated frameworks.
  3. Add sparse framework overrides only for real framework-specific differences.
  4. Do not hand-edit generated files under src/data/frameworks/.
  5. Validate routes, sidebar state, search results, snippets, and framework switching.

Authored Framework Docs

Authored frameworks use docs_mode: authored. The framework owns an MDX tree under src/content/docs/integrations/<docsFolder>/ with a meta.json sidebar.

To update authored docs:

  1. Check getDocsFolder() in src/lib/registry.ts; the URL slug and folder name may differ.
  2. Edit the MDX page under src/content/docs/integrations/<docsFolder>/.
  3. Update that folder's meta.json when adding, removing, or moving pages.
  4. Reuse shared snippets from src/content/snippets/ when content should stay consistent across frameworks.
  5. Validate the framework route, sidebar, search result, and any shared snippet render.

Reference Docs

Edit API reference pages under src/content/reference/.

The v2 reference does not use meta.json; navigation is generated by walking the tree and reading each page's title and description frontmatter. Only the legacy reference/v1/ tree uses meta.json.

Snippets

Reusable snippets live under src/content/snippets/. Snippets may be rendered by root docs, authored framework pages, and showcase-driven framework pages, so keep them general unless the path is intentionally framework-specific.

Frontend Applicability

Frontend routes use page-level applicability metadata, independent from where the content is authored. A page can be authored MDX, showcase-generated content, mirrored protocol docs, or reference content and still be universal across frontends.

Use the frontend field in page frontmatter or meta.json when a root doc should appear in non-React frontend docs:

  • universal — render the same page under /<frontend>/....
  • frontend-variant — render only when a matching page exists under src/content/docs/frontends/<frontend>/....
  • hide — omit the page from frontend-scoped docs.

Do not use "showcase-driven" as a proxy for frontend availability. Showcase derivation is an authoring/source detail; frontend applicability controls routing and sidebar inclusion.

AG-UI Mirrored Docs

AG-UI protocol docs are authored upstream in ag-ui-protocol/ag-ui. The src/content/ag-ui/ tree is a downstream mirror rendered on the CopilotKit docs host. Change AG-UI docs upstream first, then sync the mirror back into shell-docs.

The repository's top-level docs/ path is a symlink to showcase/shell-docs/ for contributor muscle memory. It is not a separate docs app. Do not recreate the old docs/content/docs/ tree; author CopilotKit docs in showcase/shell-docs/src/content/.
