Summary

Before this PR, a SaaS user's chat turn never reached inference. A new end-to-end test caught it. There were two causes; each one alone was enough to block the turn.

  1. The agent-definition registry was never initialised in SaaS. Bootstrap initialises it only when the Agent domain is on, which SaaS leaves off. With no registry, every turn failed with hosted root invocation is unavailable because the session has no hosted authority. saas::build now seeds the registry with the built-in definitions only. The registry is process-wide and the first initialiser wins, so seeding it at boot also stops a lazy init (agent/registry/ops.rs, parent_context/builder.rs, agent/library/ops.rs) from loading one user's workspace definitions for every user.
  2. The scheduler gate's "signed out" flag was process-wide. The operator holds no credential, so boot set it to signed out. Every session-credential user's managed inference was then refused with SESSION_EXPIRED (openhuman_backend_model.rs), and one user's expiry would have signed out everyone. In SaaS, is_signed_out() is now always false and set_signed_out() does nothing. Each user's credential is checked against their own auth-profile store when it's used.
    • SessionExpiredSubscriber does no process-wide teardown in SaaS. The gateway owns refreshing a user's credential (user_agents.set_credential), and the failing call already reports the 401 to that user.

Also included: the merge of upstream/main brought in 7 new SaaS ambient-state sites. They are converted here: 6 bare spawns now go through spawn_scoped / spawn_blocking_scoped, and thread_delete uses load_config_with_timeout. The ratchet goes from 201 to 199.

Stacking

The chain below this has merged and main has been merged in, so this PR now carries only its own changes: saas.rs, scheduler_gate/gate.rs, credentials/bus.rs and the end-to-end test. Its ambient-state spawn conversions already reached main through the Phase 2 merge.

Test plan

  • New end-to-end test a_users_turn_reaches_inference_with_their_own_credential. Alice gets a session credential and a local listener stands in for the backend; the test asserts that a /chat/completions request arrives with Bearer alice-session-jwt. On failure it prints the core's log.
    • It fails without the registry fix.
    • With the registry fix but without the gate fix, it also fails.
    • It passes with both.
  • cargo test -p openhuman-cli --test saas_mode_e2e: 9 passed.
  • RUST_MIN_STACK=16777216 cargo test -p openhuman --lib -- memory:: cron::scheduler threads::ops: 515 passed.
  • cargo test -p openhuman --lib -- cron::scheduler_gate security::credentials core::runtime user_agents::: 423 passed.
  • cargo clippy -p openhuman -p openhuman-cli --all-targets and cargo fmt: clean. pnpm saas:ambient: holds at 199.

Summary by CodeRabbit

Add an end-to-end test asserting that a user's chat turn reaches the
inference backend carrying that user's own credential, even when the
operator holds none. A recording backend captures each request's path and
Authorization header so the test can verify the key that was sent.

The end-to-end test now sets a session credential instead of an API key and asserts that the session JWT reaches inference, matching the credential kind the flow actually uses.

Print the matched request path and drain any remaining requests after the
assertion so the test's observed traffic can be inspected when it fails.

The test now matches on the request path instead of the auth header when
waiting for a turn to reach inference, and the debug helper that drained
the channel after a fixed sleep has been removed. This makes the wait
condition explicit and drops the leftover debugging scaffolding.

The scheduler gate's signed-out flag and the session-expired subscriber now
no-op in SaaS mode, since signed-in state is per user and the gateway owns
credential refresh; a single process-wide flag would let one user's expiry
stop every user's model calls.

The spawned core process now runs with debug logging enabled and its stderr redirected to a log file instead of being discarded, so failures in this end-to-end test can be diagnosed from the captured output.

When alice's turn never reaches inference, the test now reads core.log and
appends the last 40 WARN/ERROR lines to the panic message, making failures
easier to diagnose without rerunning.

The failure diagnostic now collects all log lines except scheduler_gate noise instead of only WARN and ERROR entries, and shows more of the tail. This surfaces the request-handling context needed to debug why a user's turn never reached inference.

The spawned core process now writes stdout to core.log and discards stderr, swapping the two streams so the log captures the output the test actually inspects.

The SaaS runtime now initialises the global agent definition registry with
built-ins only, so the process-wide registry is populated before any lazy
initialisation can load a single user's workspace definitions for all users.
A log line reports how many built-in definitions were registered.

Replaced bare tokio spawn and spawn_blocking calls in cron delivery, memory
import and conversion, layout migration, and thread deletion with the scoped

deletion now loads config through the timeout-aware RPC loader, and the SaaS
ambient baseline was refreshed to match the shifted line numbers.

📝 Walkthrough

Walkthrough

The SaaS runtime enables per-user threads, channels, and memory, initializes built-in agent definitions, and avoids process-wide sign-out and session teardown. End-to-end tests check user-facing method availability and forwarding a user’s stored session credential with a chat request.

Changes

SaaS Runtime Isolation

Layer / File(s) Summary
SaaS runtime setup
crates/openhuman-core/src/core/runtime/saas.rs, crates/openhuman-core/src/memory/engine.rs
The runtime documentation describes the enabled per-user families. Runtime construction initializes the agent registry with built-in definitions. SaaS memory binding excludes the process-wide host engine.
SaaS session state and credential handling
crates/openhuman-core/src/cron/scheduler_gate/gate.rs, crates/openhuman-core/src/security/credentials/bus.rs
In SaaS mode, sign-out queries return false, sign-out updates do not change the process-wide flag, and session-expiration handling returns without process-wide teardown.
SaaS end-to-end coverage
tests/saas_mode_e2e.rs
Tests check the operator plane’s user-family scope, an unknown method in a user request, and the authorization header on a provisioned user’s chat request.

What changed

In SaaS mode the per-user surface is now open for the threads, channels (web chat), and memory families alongside the operator plane: `DomainSet::saas` enables those user families whose per-user isolation has landed, so a SaaS core no longer refuses every user domain method as unknown. In `saas::build`, built-in agent definitions are seeded at boot via `AgentDefinitionRegistry::init_global_builtins` before the process serves requests, which also prevents a lazy init from loading one user's workspace definitions for everyone, since the registry is process-wide and the first initialiser wins. The scheduler gate becomes per-user aware: `is_signed_out` always returns `false` in SaaS mode (signed in is a fact about each user, checked against that user's own credential when it is used), and `set_signed_out` ignores process-wide signed-out writes in SaaS mode, so one user's expiry or the operator's lack of a credential can no longer park every user's model calls. The credential bus's SessionExpiredSubscriber does nothing process-wide in SaaS mode: it logs a warning and returns before standing down background workers, leaving the credential's refresh to the gateway via `user_agents.set_credential`; the failing call already reports the 401 to that user. In memory binding, `bind_with_root` no longer hands out the process-wide host engine in SaaS mode (treated as `None`), so a SaaS process never shares the host engine across users; the existing error that the host engine cannot be bound below a scope root, and the fallback to the host engine when no root is given, now use this SaaS-aware value.

Features

  • Modified — Per-user SaaS domain surface: threads, channels (web chat), and memory served to users: A SaaS core now answers the user families whose per-user isolation has landed (threads, channels for web chat, memory) in addition to the operator plane (`user_agents.*`); the operator scope reaches only its own plane and a user only the reviewed `user_agents::surface::USER_METHODS`. Previously the presets were closed and every user domain method was refused as unknown. (crates/openhuman-core/src/core/runtime/saas.rs#pub async fn build()
  • Modified — Built-in agent definitions seeded at SaaS boot: `saas::build` seeds the process-wide built-in registry (`AgentDefinitionRegistry::init_global_builtins`) before serving, logging the count of built-ins and that there are no workspace or home overrides. Because the registry is process-wide and the first initialiser wins, seeding here also stops a lazy init from loading one user's workspace definitions for everyone. A review finding that the built-in registry must be initialised before the runtime is built was resolved by this change. (crates/openhuman-core/src/core/runtime/saas.rs#pub async fn build()
  • Modified — Per-user sign-in state: process-wide signed-out flag disabled in SaaS mode: `is_signed_out` always returns `false` in SaaS mode (a cheap atomic load remains safe for hot paths such as the per-LLM-call short-circuit in `OpenHumanBackendModel`), and `set_signed_out` ignores process-wide signed-out writes in SaaS mode with a debug log. Signed-in is now a per-user fact checked against that user's own credential when it is used, so one user's expiry (or the operator's lack of a credential) no longer stops every user's model calls or parks calls forever in the `paused_poll_ms` branch of `wait_for_capacity`. (crates/openhuman-core/src/cron/scheduler_gate/gate.rs#pub fn current_policy() -> Policy {, crates/openhuman-core/src/cron/scheduler_gate/gate.rs#pub fn is_signed_out() -> bool {)
  • Modified — SessionExpired handled per-user in SaaS mode (no process-wide teardown): In SaaS mode the SessionExpired subscriber logs a warning and returns before any process-wide teardown (no standing down of background workers), since each user's credential belongs to that user and the gateway owns its refresh via `user_agents.set_credential`; the failing call already reports the 401 to that user. Without this, a 401 from a background LLM call would be detected but never acted on in non-SaaS mode. (crates/openhuman-core/src/security/credentials/bus.rs#impl EventHandler<DomainEvent> for SessionExpiredSubscriber {)
  • Modified — Host memory engine excluded from per-user binding in SaaS mode: `bind_with_root` treats the process-wide host engine as `None` in SaaS mode, so a SaaS process never hands out the host engine that every user would share; the guard against binding the host engine below a scope root and the no-root fallback now consult this SaaS-aware value. (crates/openhuman-core/src/memory/engine.rs#pub fn bind_with_root(config: &Config, root: Option<&str>) -> MemoryResult<Bound)

Tests

  • e2e — `a_users_turn_reaches_inference_with_their_own_credential`: with an operator holding no credential, provisions user alice, sets alice's session credential via `openhuman.user_agents_set_credential`, sends a web chat message (`openhuman.channel_web_chat`), and waits on a recording backend (which answers every request `500` and reports each request's path and `Authorization` header) for a request whose path contains `/chat/completions`; on timeout it dumps the last 120 lines of the core log excluding `[scheduler_gate]` lines plus the count of other requests seen, and asserts the inference request's `Authorization` equals `Bearer alice-session-jwt`.: Covers the is_signed_out SaaS no-op end to end and matches the description. Note the recording backend answers 500, never 401, so nothing drives set_signed_out being ignored; the SessionExpired subscriber's SaaS no-op remains uncovered end to end. Waiting on end-to-end jobs: `Rust E2E (mock backend)`, `Build Playwright E2E Artifact`, `E2E (Playwright / web lane)`, `Desktop E2E (full suite, 3 OS)`. (tests/saas_mode_e2e.rs)
  • e2e — `a_safe_deployment_serves_core_and_the_operator_plane_behind_the_gateway_beare` now asserts, for each of `openhuman.threads_list` and `openhuman.config_get_config` and other listed methods, that the operator plane serves none of the user families.: Updated expectation for the new per-user surface; covered by this test as written. (tests/saas_mode_e2e.rs#fn a_safe_deployment_serves_core_and_the_operator_plane_behind_the_gateway_beare)
  • e2e — `each_user_sees_only_their_own_threads` replaces the threads_regenerate error assertion with `openhuman.config_get_config` called by alice, asserting the body contains "unknown method" because a method off the user surface is unknown, not a parameter error.: Updated expectation for the new per-user surface; covered by this test as written. (tests/saas_mode_e2e.rs#fn each_user_sees_only_their_own_threads() {)
  • e2e — `users_reach_their_memory_but_not_its_configuration` covers users reaching their memory but not its configuration.: Covered by this test as written. (tests/saas_mode_e2e.rs#fn users_reach_their_memory_but_not_its_configuration() {)

  • Positive: This revision adds a real end-to-end test that drives a SaaS core with a per-user credential through channel_web_chat to inference, which covers the is_signed_out SaaS no-op, and the global built-in registry is now seeded before the server serves requests, resolving the earlier initialization finding.

The built-in registry is now initialised in `saas::build`.

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: This revision fixes the registry-initialisation finding by seeding built-in agent definitions in `saas::build`, and the new end-to-end test matches the description. The gate and SessionExpired SaaS no-ops still lack dedicated tests; those findings stand. Otherwise the change looks sound.

  • Conclusion: Neutral
  • Scope reviewed: all assigned evidence
  • Lane summary: This revision adds a real end-to-end test that drives a SaaS core with a per-user credential through channel_web_chat to inference, which covers the is_signed_out SaaS no-op, and the global built-in registry is now seeded before the server serves requests, resolving the earlier initialization finding. What remains uncovered end to end is the write side: the SessionExpired subscriber's SaaS no-op (the recording backend answers 500, never 401, so nothing drives set_signed_out being ignored). Waiting on end-to-end jobs: `Rust E2E (mock backend)`, `Build Playwright E2E Artifact`, `E2E (Playwright / web lane)`, `Desktop E2E (full suite, 3 OS)`. (3 earlier finding(s) still open)

Inline comments:
Review comments at @crates/openhuman-core/src/core/runtime/saas.rs:
- Around line 10-15: Update the SaaS preset documentation to reflect the enabled
operator plane and `threads`, `channels`, and `memory` families behind
`USER_METHODS`. In `crates/openhuman-core/src/core/runtime/saas.rs` lines 10-15,
remove claims that only the operator plane is enabled and all user domain
methods are refused; in `crates/openhuman-core/src/core/runtime/README.md` lines
173-177, list all three families and add `require_user_signature` to the
`SaasConfig` keys; in `crates/openhuman-core/src/user_agents/README.md` lines
91-98, replace “threads so far” with all three families. Also correct the
outdated “has no domain family … yet” rule in
`crates/openhuman-core/src/user_agents/README.md` lines 34-37.

Review comments at @crates/openhuman-core/src/memory/engine.rs:
- Around line 220-225: Update bind_with_root to apply the same SaaS gate used by
resolve when obtaining the host engine. Reuse that gated host value for both the
rooted-bind rejection and root-less binding, so SaaS mode ignores the host
engine in both cases.

Review comments at @crates/openhuman-core/src/user_agents/host.rs:
- Around line 234-236: Update the agent iteration in `list` to handle each
`self.summary(&id)` result independently: add successful summaries, ignore
missing agents, and log summary errors before continuing to the next agent
instead of propagating the error.

Review comments at @crates/openhuman-rpc/src/server/saas_gateway.rs:
- Around line 78-84: Update the user-header handling around USER_HEADER in the
gateway middleware to distinguish an absent header from one that cannot be
decoded by header_str. Preserve the operator-plane fallback only when the header
is absent; return 400 for a present but unreadable header before running the
request or resolving its scope.

Review comments at @scripts/ci/check-saas-ambient.mjs:
- Around line 91-95: Update the RULES scan in the source-checking function to
match calls across line boundaries in comment-filtered source, then map each
match back to its source line for reporting. Add a multiline-call test covering
tokio::spawn and Config::load_or_init split before the opening parenthesis.
- Around line 75-84: Update codeOf to exclude quoted strings and block comments
from the text scanned by the rules, while preserving its handling of line
comments. Add tests confirming tokio::spawn text in a string or block comment
does not produce a finding.

Review comments at @tests/saas_mode_e2e.rs:
- Around line 527-528: Update the surface-gating assertion in the test to call
an off-USER_METHODS method such as openhuman.config_get_config and verify the
response reports “unknown method”; the current threads_regenerate call only
tests parameter validation. Revise the nearby turn-starting-methods comment and
the outdated comment stating no domain family is isolated per user to match
current behavior.

The module docs now state that the SaaS preset serves the operator plane
alongside the user families whose per-user isolation has landed, and that
build seeds the built-in agent definitions. The e2e comments and the
unknown-method assertion were updated to match the current surface.

Reject a pre-existing workspace registry before SaaS boot.

The SaaS builder does not initialize the registry because the Agent domain is disabled. However, the RPC-bound handle_list_definitions path can call AgentDefinitionRegistry::init_global() before saas::build(). The later init_global_builtins() call then keeps that workspace registry because GLOBAL is a process-wide OnceLock.

Make SaaS boot reject a pre-existing non-builtins registry instead of silently ignoring the failed GLOBAL.set.

Initialize the built-in registry before building the runtime

The spawned SaaS core still reaches runtime construction without initializing the built-in registry, so this test process can fail during startup before it reaches the credential assertion. Initialize the registry before constructing the runtime; otherwise the newly added end-to-end test cannot provide coverage and the SaaS binary remains unusable on this path.

Reject an existing registry that is not builtins-only

init_global_builtins() always returns Ok(()) even when GLOBAL was already initialized, so this call does not guarantee the registry contains only built-ins. For example, if another host first calls init_global(&workspace), this SaaS boot continues using that workspace's custom definitions despite the comment and log claiming “no workspace or home overrides.” The SaaS path should detect and reject a pre-existing non-builtins registry, or use an initialization API that enforces the required contents.

Cover the SaaS no-op in set_signed_out

This test covers per-user credential propagation, but it does not exercise the SaaS set_signed_out path. The previously identified no-op can regress without any assertion in this file detecting it; add a test that invokes the operation in SaaS mode and verifies the expected no-op behavior.

Cover the SaaS no-op in the SessionExpired subscriber

The new test only drives a successful user turn and never emits or handles SessionExpired, so it does not cover the SaaS subscriber's intended no-op behavior. Add a regression test that triggers this event in SaaS mode and asserts that it neither mutates state nor causes an error.

Add an end-to-end test for SessionExpired in SaaS mode

This end-to-end flow reaches channel_web_chat but never exercises the SessionExpired event path. Consequently, the SaaS-specific no-op behavior of that subscriber remains unverified at the system boundary. Add a separate end-to-end scenario that causes session expiration and checks the resulting SaaS behavior.

Cover the SessionExpired SaaS no-op end to end

The documented SaaS isolation boundary is changing, but there is still no end-to-end test exercising SessionExpired through the SaaS runtime. Add an E2E case that verifies the event is accepted without performing the user-domain side effects.

Cover the SaaS no-op in set_signed_out with a test

Still no test exercises this branch: dropping the guard would silently reintroduce the process-wide stand-down in SaaS mode, and nothing in the diff would fail. A unit test in the sibling gate_tests.rs (mode forced to SaaS, call set_signed_out(true), assert SIGNED_OUT stays false / is_signed_out() stays false) would pin it.

// SaaS: the credential belongs to one user and the gateway owns its

Cover the SaaS no-op in the SessionExpired subscriber

The early return that skips process-wide teardown on SessionExpired in SaaS mode still has no test: no unit test feeds a SessionExpired event in SaaS mode and asserts the scheduler was not stood down, and no e2e test shows that a 401 from one user's call does not stop other users' calls. Removing these lines would not fail anything in this diff. The repo rule that tests accompany behaviour applies.

Add a test for the SaaS host-engine exclusion in memory binding

This new branch (SaaS binding never falls back to the process-wide host engine) has no coverage: no test installs a host engine, boots SaaS, and asserts the bound engine is not the host one. If the guard were removed, per-user memory would silently share the host engine and nothing would fail. A test asserting that in SaaS mode the resolved engine's id is not HOST_ENGINE_ENDPOINT-based would pin it.

Drive a 401 in SaaS mode to cover the SessionExpired no-op

The new test a_users_turn_reaches_inference_with_their_own_credential covers the reader side of the scheduler gate (is_signed_out returning false in SaaS), but the write side — set_signed_out ignoring the flag in SaaS — is reached only via the SessionExpired subscriber in crates/openhuman-core/src/security/credentials/bus.rs, and no end-to-end test triggers it: the fake backend answers 500 to everything, never 401. A test would have to answer a model call with 401, then assert the process keeps serving other turns (no process-wide teardown / signed-out parking) — exactly the scenario the PR's own comment claims is handled by the gateway. This remains uncovered from the earlier round.
