fix(saas): user turns reach inference — per-user sign-in state, built-in definitions at boot - #7161
Conversation
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
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. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Replaced bare tokio spawn and spawn_blocking calls in cron delivery, memory import and conversion, layout migration, and thread deletion with the scoped runtime helpers so spawned tasks inherit the ambient runtime context. Thread deletion now loads config through the timeout-aware RPC loader, and the SaaS ambient baseline was refreshed to match the shifted line numbers.

Tiny Sweeper reviewTiny Sweeper completed its review; deterministic results follow. State: Changes requested Review snapshot
Completeness: Complete What changedIn 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.

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.

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.

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.

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.

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.

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.
Agentdomain is on, which SaaS leaves off. With no registry, every turn failed withhosted root invocation is unavailable because the session has no hosted authority.saas::buildnow 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.SESSION_EXPIRED(openhuman_backend_model.rs), and one user's expiry would have signed out everyone. In SaaS,is_signed_out()is now alwaysfalseandset_signed_out()does nothing. Each user's credential is checked against their own auth-profile store when it's used.SessionExpiredSubscriberdoes 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, andthread_deleteusesload_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.rsand the end-to-end test. Its ambient-state spawn conversions already reached main through the Phase 2 merge.Test plan
