## 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.
