Add the hosting domain: deploy a workspace to a real hosting provider - #5578
Conversation
Introduce a new `hosting` feature that wires the `tinyhosts` crate as an optional dependency, adds a `HostingConfig` struct to the configuration schema, and conditionally compiles the `openhuman::hosting` module. This provides a unified hosting API for deploying workspaces to providers like Vercel, gated behind a default-off feature flag so that the agent tools are only available when a hosting credential is configured.

Vendors tinyhosts and exposes six hosting_* tools behind a default-OFF `hosting` feature. Credentials come from [hosting].api_key or the provider's environment variables, and the tools are registered only once one resolves. Co-authored-by: Medulla <medulla@tinyhumans.ai>

envvalue coercion turns a JSONnullinto the string"null". Both sites use the same fallback,value.as_str().map(ToOwned::to_owned).unwrap_or_else(|| value.to_string()). The inline comment justifies the fallback for a number or a bool, which is reasonable. It also catchesnull, an array, and an object:nullbecomes the four-character variable value"null", and a container becomes its JSON text. A build-time variable set to"null"is a silent wrong value rather than an unset one. The declared schema isadditionalProperties: {"type": "string"}, so a compliant model never reaches this, but the two copies can also drift apart.Extract one helper that rejects
nulland containers, and call it from both sites.

- Around line 651-675: Update the breakdown handling in the AnalyticsQuery
construction to report an unrecognized breakdown value instead of silently
omitting it and running an aggregate query. Preserve the existing mappings for
the seven supported names, and return the tool’s established error result for
any other provided value.

excluded when Integrations is disabled instead of defaulting to
DomainGroup::Platform.

…e handling The HostingConfig debug implementation now redacts the api_key field to prevent credential leakage through nested debug formatting. Environment variable parsing in LaunchSiteTool and SetEnvTool is extracted into a dedicated `env_value` function that rejects null and container values with a clear error, replacing the previous silent conversion. The AnalyticsTool breakdown parameter now returns an explicit error for invalid dimension names instead of silently ignoring them, and the tool group classification in ops.rs ensures hosting tools are correctly gated under the Integrations domain group.

The `hosting` family has never been compiled in any configuration. Its gate in
the root Cargo.toml declares its own intent:
# ... Default-OFF, product-ON: a host with no hosting credential has no use
# for the tools, and an agent that can deploy to the internet is authority a
# headless embedding should have to ask for.
but `hosting` appears in neither `scripts/ci/product-features.txt` nor the
shell's forwarding list in `app/src-tauri/Cargo.toml`, and it is not in
`default`. So 1,643 lines - including a 511-line test file and nine `hosting_*`
agent tools - are compiled by nothing, tested by nothing, and shipped in
nothing.
This is the same shape as #4901, where `voice` shipped missing to 56 users. The
feature-forwarding gate built to prevent a recurrence passes here, because it
asserts set equality between two lists and `hosting` is absent from both. A gate
cannot catch a feature nobody told it about.
It also explains the CI observation in #5593: `Rust Core Coverage` reported
success having run `0 tests; 12202 filtered out`, because the feature under test
was in no CI command.
Everything else is already wired correctly - `src/openhuman/mod.rs:29` declares
the module behind the gate, and `tools/ops.rs:1031` registers the tools. That
registration is credential-gated on `Account::from_config`, so enabling the
feature adds no tools for a host without `[hosting].api_key` or the provider's
environment variable. Users who have not configured hosting see no change.
Verified `scripts/ci/check-feature-forwarding.mjs` passes with both lists moved
together (19 shell forwards).
