Merge Risk: 🟡 Moderate · up to Sponsorship requests can expose credentials, hang indefinitely, or violate the SDK's typed response and error contracts.

In `@docs/api-reference.md`:
- Line 74: Update the submit API documentation to describe streamTokenId as
nullable, noting that it may be unavailable until the backend confirms stream
creation. Replace the unconditional “confirmed NFT token ID” wording while
retaining the other documented return fields.
In `@docs/generated-bindings.md`:
- Around line 76-77: Add the Lockup contract release tag and the exact
generation command `pnpm generate:lockup -- /absolute/path/to/lockup.wasm` to
the provenance record, alongside the existing binding details, so the Lockup
artifact can be reproduced.
In `@README.md`:
- Line 50: Update the README capability availability statement so Flow, Router,
and Stream NFT depend on their corresponding contract IDs, while sponsorship
depends on a configured sponsorship.backendUrl; replace the existing wording
that incorrectly requires contract IDs for every capability.
In `@src/stellar/sponsorship-client.ts`:
- Line 159: Update the backendUrl validation in the sponsorship client
constructor or initialization flow to reject non-HTTPS URLs by default, while
permitting HTTP only when the explicit local-development option is enabled.
Preserve the existing trailing-slash normalization after validation and ensure
authenticated requests cannot use plaintext transport unless that option is
active.
- Line 204: Update the session response handling around the wallet network field
to validate the required value against the allowed “MAINNET” and “TESTNET”
strings before casting or returning it, throwing API_REQUEST_FAILED for any
other value. Add a malformed-response test covering invalid casing or
unsupported network values.
- Around line 310-321: Update StellarSponsorshipClient.request() to apply a
configurable bounded timeout to the fetcher request, aborting it when the
timeout expires and mapping the timeout outcome to
FUNDABLE_ERROR_CODES.API_REQUEST_FAILED. Preserve existing request options and
error handling for non-timeout responses.
- Line 310: Update the request method around the this.fetcher call to catch
transport rejections and throw FundableError with code API_REQUEST_FAILED, chain
"stellar", and the original error preserved as cause, while leaving successful
responses and existing mappings unchanged.

Document streamTokenId as nullable. StellarSponsorshipClient.submit maps a missing or non-empty streamId response to StellarSponsorSubmission.streamTokenId: string | null. State that the token ID may be unavailable until the backend confirms stream creation; do not describe it as unconditionally confirmed.

Complete the mainnet-readiness provenance record.
The section must include the contract release tag and the exact command for each binding. Add the release tag and pnpm generate:lockup -- /absolute/path/to/lockup.wasm; the current command list does not reproduce the Lockup artifact.

Correct the capability availability condition.
Sponsorship does not depend on a contract ID. It becomes available when sponsorship.backendUrl is configured.
Replace “when their contract IDs are configured” with “when their corresponding contract IDs or sponsorship backend URL are configured.”

Wrap transport failures in FundableError.
When this.fetcher(...) rejects, request bypasses the existing API_REQUEST_FAILED mapping and exposes the native error. Catch the rejection and throw FundableError with chain: "stellar" and the original error as cause.

Add a bounded request timeout.
If the backend does not complete the response, StellarSponsorshipClient.request() can wait indefinitely. This affects authentication, quoting, building, and submission. Add a configurable timeout, abort the request when it expires, and map the timeout to FUNDABLE_ERROR_CODES.API_REQUEST_FAILED.

Updates @fundable/sdk to the post-readiness Stellar contracts and sponsorship API. The release adds regenerated Flow, Lockup, Router, and Stream NFT bindings; canonical stream metadata and lifecycle queries; first-class Lockup and sponsorship clients; and migration deprecations for the legacy Paymaster API.
