feat(product): identify this crate's backend traffic as opencompany - #513
Conversation
OpenCompany, OpenHuman and Medulla share a single TinyHumans login, so the backend cannot attribute a request to a product from credentials alone. Every backend-bound request this process makes now carries `x-sdk-name: opencompany`, which the backend already parses. OpenCompany reaches the backend two ways, and they need separate treatment: - Through the embedded `openhuman_core`, whose `IntegrationClient` backs the media, Composio and web-search tools. One `install_into_embedded_core()` call during startup covers all of them. It has to run before any company runtime, agent harness or HTTP listener exists, because core reads the identity into a client's default headers at construction and would not retroactively re-tag a client that already exists. - Through this crate's own `reqwest` clients, which bypass `openhuman_core` entirely and inherit nothing from that call. These carry the majority of the traffic, including the sole production inference path, so each attaches the header itself: `HostedProvider`, `HostedEmbeddings`, the Medulla `HttpSocketTransport`, the feedback hub client, and the hub identity exchange. `request_plan` attaches the header only when the provider is `managed`. The other three `INFERENCE_PROVIDERS` are bring-your-own-key endpoints pointed at OpenAI, OpenRouter, DeepSeek or a self-hosted Ollama; sending them our product identity would disclose which TinyHumans product a tenant runs to a company with no relationship to us, and buy nothing. A test pins the negative case. `src/product.rs` is the single source of truth for the string, so `feedback::tinyhumans::PRODUCT` re-exports it rather than keeping a second literal. The module is deliberately ungated: `harness/` sits behind the `openhuman` feature but `brain/` and `feedback/` do not, and both need the constant. Only the core-interop function is feature-gated. `install_into_embedded_core` lives in the library rather than inline in the binary so a test can reach it — the binary's `serve` arm cannot be exercised from one, and an untested call is exactly where a product-attribution bug would sit unnoticed, since nothing misbehaves when the identity is wrong. Traffic is just silently counted as another product's. The submodule pin is intentionally not bumped here: the API this consumes lands in tinyhumansai/openhuman#5437, and pinning `vendor/openhuman` at an unmerged branch commit would dangle once that branch is rebased or squashed. Verified locally against that branch with the pin moved in the working tree only.

Important
Blocked on tinyhumansai/openhuman#5437 merging. That PR adds the
openhuman_core::api::product_identitysurface this consumes; until it lands andvendor/openhumanis bumped to include it, this branch does not compile. The pin bump is deliberately not part of this diff — see Submodule pin below.Summary
Attributes this process's TinyHumans backend traffic to
opencompanyvia thex-sdk-nameheader, so the backend can tell OpenCompany users apart from OpenHuman and Medulla users who share the same login.Two halves, because OpenCompany reaches the backend two different ways:
install_into_embedded_core()call during startup setsopenhuman_core's process-wide product identity, which tags everyIntegrationClientthe harness builds (media, Composio, web search).reqwestclients — five call sites that bypassopenhuman_coreentirely and therefore inherit nothing from that call. These are the majority of OpenCompany's backend traffic, including the sole production inference path.src/product.rsis the single source of truth for the string"opencompany";feedback::tinyhumans::PRODUCTnow re-exports it instead of holding a second literal.API Or Behavior Changes
No breaking changes. No public signature changes, no removals.
feedback::tinyhumans::PRODUCTkeeps its type and value — only its definition moved behindcrate::product::PRODUCT_IDENTITY.New public API (all additive):
opencompany::product::{PRODUCT_IDENTITY, PRODUCT_IDENTITY_HEADER, product_identity_header, install_into_embedded_core}. The module is ungated;install_into_embedded_coreis#[cfg(feature = "openhuman")].Behavior change: requests to the TinyHumans backend now carry one additional ~20-byte header. Nothing observable changes yet — the backend currently discards the value (
extractSdkSourceFromRequesthas no production caller, andtrackUsage.tsdestructuressdkSourceonly to drop it), so this is inert until tinyhumansai/backend#1214 lands.Where the header is and is not attached

The other three are bring-your-own-key endpoints an operator points at OpenAI, OpenRouter, DeepSeek or a self-hosted Ollama. Sending themx-sdk-namewould disclose which TinyHumans product a tenant runs to a company with no relationship to us, for no benefit to anyone. There is an explicit negative test for this; please don't "simplify" it into an unconditional attach.The call site list was derived by enumerating every consumer of
AppConfig::api_url(which defaults toDEFAULT_API_URL = "https://api.tinyhumans.ai") rather than by grepping the diff, which is howHttpHubIdentityExchangewas caught — it was missed on the first pass.Tests
cargo fmt --all -- --checkcargo clippy --all-targets -- -D warningscargo build --all-targetscargo testRun as
--features openhuman,tinycortex(the gated lane), since everything here is behind that feature set.Added:
tests/product_identity.rs— the acceptance criterion proper: asserts the identity is the inheritedopenhumandefault beforeinstall_into_embedded_core()andopencompanyafter. The before-assertion is the half that carries the weight; without it the test would still pass if the call were deleted outright. An integration target rather than a unit test because core's identity is process-global — an in-crate test would share it with parallel unit tests and the ordering assertion would surface as a flake. Gated onopenhumanalone soscripts/ci/assert-integration-targets-run.shsees a non-zero count rather than an empty binary.src/product.rs— drift guard asserting our header name equalsopenhuman_core::api::PRODUCT_IDENTITY_HEADERand our identity differs from its default, so the two crates cannot diverge silently; plus a pin thatfeedback::tinyhumans::PRODUCTstays wired to the shared constant, so the duplicate literal cannot come back.harness/provider.rs—request_planattaches the header formanaged, and does not foropenrouter(whose own attribution headers are asserted unaffected) oropenai_compatible.harness/embeddings.rs— wire-level proof: an axum stub on an ephemeral port captures a real request and assertsx-sdk-name: opencompanyarrives.HostedEmbeddingswas chosen of the direct clients becauseharness/already compiles under plain--features openhuman, whereas the feedback and Medulla clients sit behind thetinyhumans/medullafeatures.Documentation
src/product.rs's module doc is the reference for this: why the header exists, why the module is ungated, why each direct client must attach it itself, and why the value is defined exactly once. No separate doc page — the rule belongs next to the constant it governs.Submodule pin
vendor/openhumanis intentionally not bumped in this diff. Theopenhuman_core::api::product_identitysurface lands in tinyhumansai/openhuman#5437, which is not yet merged. Pinning a submodule at an unmerged branch commit would leave a dangling reference the moment that branch is rebased or squashed on merge.Verified locally against
0574d1ca9(the #5437 head) with the pin moved in the working tree only.tinyagentslockstep holds at that commit —vendor/openhuman's own pin and this repo's are both3e1dbea5, so the eventual bump should not need to movetinyagents.Sequence to land: merge #5437 → bump
