fix(storage): fail closed when a background owner can't be resolved (review round 2 of #7207)

[senamakel]

Summary

Second review round for the storage scope work that landed in #7204 / #7207. #7207 merged before these fixes were pushed. Most of the changes make background work fail closed where it used to fall back to local:

• within_agent refuses rather than runs as local. When no context can act for the named agent, the work is skipped and returns None. The device bus drops the frame, and flow triggers, run digest, dedup and the notification bridge skip the event.
• find_owner returns a Result. A failed lookup (LookupFailed) is no longer read as "belongs to local"; one shared decide resolves the scope.
• Fallback contexts come from the process default context, and the local pass runs under it, not under whatever context the caller happened to hold.
• Device owners: revoked devices are excluded, and cached owners are re-validated.
• Flows: the run digest and dedup settlement use the owner's config (flows::bus::owner::config_for_scope). The boot sweep skips every shared backend.
• Task sources: the connection subscriber loads its config inside each scope.
• CI: pnpm rust:clippy fails on main with result_large_err in server/saas_gateway.rs. Fixed with the same #[allow] and reason http_host::auth uses for the same axum Response error type.

Problem

• Round-two review findings on feat(storage): event subscribers act as the agent whose record the event names #7207: several paths treated "couldn't determine the owner" as "the owner is local". On a multi-agent host that writes one agent's record into another scope.

Solution

• An explicit lookup error and a skip-on-unknown-agent rule at every call site, plus owner-config resolution for the flow settlement paths.

Submission Checklist

• Tests added or updated:
  • storage/agents_tests.rs: refusal when no context can act, lookup errors, fallback from the default context;
  • security/devices/owner_tests.rs: revoked devices, cache re-validation;
  • flows/bus/owner_tests.rs, flows/ops_tests.rs: owner config, shared-backend boot sweep;
  • tests/storage_scope_e2e.rs.
• Diff coverage ≥ 80%: CI Fast passed (diff-cover gate).
• Coverage matrix updated: N/A.
• Affected feature IDs: N/A.
• No new external network dependencies.
• Manual smoke checklist: N/A, desktop unchanged.
• Linked issue: N/A, follow-up to feat(storage): event subscribers act as the agent whose record the event names #7207.

Impact

• Embed hosts with a storage URL: background work no longer writes into the wrong scope when an owner can't be resolved; it skips and logs instead.
• Desktop: unchanged. SaaS: unchanged.
• CI: pnpm rust:clippy passes again.

Related

• Closes: N/A
• Follow-up to feat(storage): background work visits every agent's storage scope #7204 / feat(storage): event subscribers act as the agent whose record the event names #7207.
• Follow-up PR(s)/TODOs:
  • a distributed cron claim/lease on shared backends (separate design);
  • recorded-but-not-live agents' cron jobs wait until the agent is live again.

Summary by CodeRabbit

• Bug Fixes
  • Flow events and scheduled tasks now use the correct owner’s settings, and ownership lookup failures are no longer mistaken for missing owners.
  • Task-source notifications now use settings from each storage scope, preventing one scope’s configuration from affecting another.
  • Cron completion notifications use their recorded owner. If ownership can’t be verified, they still broadcast but aren’t saved under a potentially incorrect account.
  • Revoked devices are no longer associated with an owner, and device frames without a valid handling context are dropped with a warning. Pairing state is cleared when device details can’t be saved.
  • Startup cleanup skips shared storage and covers all scopes on non-shared storage.

Features

• Modified — Fail-closed owner resolution: Background work that cannot determine which scope owns a record is skipped with a warning rather than run in the wrong scope; find_owner and flow_owner return LookupFailed when no scope reported the record and a probe failed. (crates/openhuman-core/src/storage/agents.rs#fn contexts_in(, crates/openhuman-core/src/flows/bus/owner.rs#async fn resolve(config: &Config, flow_id: &str) -> Option<String> {, crates/openhuman-core/src/security/devices/owner.rs#pub(super) async fn owner_of()
• Modified — Revoked device with live cipher fails closed: A device revoked or unpaired in another process leaves its session cipher here; its frames are dropped rather than handled as local, keeping the revoked device from gaining the operator's scope. (crates/openhuman-core/src/security/devices/owner.rs#pub(super) async fn owner_of(, crates/openhuman-core/src/security/devices/bus.rs#impl EventHandler<DomainEvent> for DeviceTunnelSubscriber {)
• Modified — Leftover pairing session does not outlive a revocation: A pending pairing session names its agent only until the handshake completes; once the process holds the channel's session cipher, the store decides liveness, so a stale session cannot vouch for a revoked device. (crates/openhuman-core/src/security/devices/owner.rs#pub(super) async fn owner_of()
• Modified — within_agent skips when no context can act: Callers named as an agent's owner but without a context to act under skip the work; the devices tunnel bus logs and drops such frames. (crates/openhuman-core/src/security/devices/bus.rs#impl EventHandler<DomainEvent> for DeviceTunnelSubscriber {, crates/openhuman-core/src/storage/agents.rs#fn recorded(backend: Arc<dyn StorageBackend>) -> Vec<String> {)
• Modified — Notification persistence skips on unknown owner: A notification whose cron-job owner lookup fails is not persisted while the live broadcast still goes out; a missing job is recognized by matching the message shape "Cron job '<id>' not found", which reviewers asked to be classified structurally. (crates/openhuman-core/src/desktop/notifications/bus.rs#impl EventHandler<DomainEvent> for NotificationBridgeSubscriber {, crates/openhuman-core/src/desktop/notifications/bus.rs#fn translate(event: &DomainEvent) -> Option<CoreNotificationEvent> {)
• Modified — Per-scope config loading and shared flow-owner helpers: Task-source and device probes load config inside each scope, so an agent whose own config disables task sources is skipped; flow subscribers share as_owner/config_for_scope so handlers run with the acting agent's own configuration. (crates/openhuman-core/src/integrations/task_sources/bus.rs#impl EventHandler<DomainEvent> for TaskSourcesConnectionSubscriber {, crates/openhuman-core/src/flows/bus/trigger.rs#impl FlowTriggerSubscriber {, crates/openhuman-core/src/flows/bus/run_digest.rs#impl FlowRunDigestSubscriber {, crates/openhuman-core/src/flows/bus/dedup_commit.rs#impl DedupCommitSubscriber {)
• Modified — Boot sweep skips all scopes on shared backends: On a shared storage backend nothing is swept at boot — including local — since a running row may belong to a run another replica is still driving; the LocalOnly plan was removed. (crates/openhuman-core/src/flows/ops/run_management.rs#pub async fn sweep_orphaned_running_runs_on_boot(config: &Config) -> usize {)

Tests

• unit — A remembered device owner whose scope lost the device is forgotten and re-resolved; a revoked device is no longer its agent's and is not remembered.: Directly covers the new cached-owner revalidation and revoked-device semantics. (crates/openhuman-core/src/security/devices/owner_tests.rs#async fn a_pending_pairing_names_its_agent() {)
• unit — A device revoked in another process leaves its session cipher here; owner_of returns an error.: Pins the new fail-closed revoked-cipher behavior. (crates/openhuman-core/src/security/devices/owner_tests.rs#fn a_failed_lookup_without_a_match_fails_closed() {)
• unit — A pairing session left over after the handshake does not vouch for a device another process has since revoked: with the cipher live, the store decides.: Pins the new pairing-session/cipher precedence rule. (crates/openhuman-core/src/security/devices/owner_tests.rs#async fn a_pending_pairing_names_its_agent() {)
• unit — A cron completion noted by the scheduler resolves to the noted agent even when the job is already gone.: Covers the scheduler-note fast path in the notification owner probe. (crates/openhuman-core/src/desktop/notifications/bus_tests_2_tests.rs#fn the_announcement_rule_fails_closed_on_an_unknown_workspace() {)
• unit — A connection event is handled through each scope's own configuration; documented as a smoke test.: The test executes the paths but asserts nothing; reviewers still asked that outcomes be asserted. (crates/openhuman-core/src/integrations/task_sources/bus_tests.rs#async fn an_unreadable_scope_is_skipped() {)
• unit — decide verdicts, find_owner fail-closed error paths, flow-owner cache lifecycle, and boot_sweep_plan verdicts.: Covers the shared decision logic, the removed LocalOnly plan, and resolve/cache revalidation under the new Result contract. (crates/openhuman-core/src/storage/agents_tests.rs#async fn without_a_backend_only_the_local_scope_runs() {, crates/openhuman-core/src/storage/agents_tests.rs#async fn without_a_backend_the_live_pass_runs_only_local() {, crates/openhuman-core/src/flows/bus/owner_tests.rs#async fn a_cached_owner_is_dropped_once_its_scope_loses_the_flow() {, crates/openhuman-core/src/flows/bus/owner_tests.rs#async fn without_a_backend_every_flow_is_local() {, crates/openhuman-core/src/flows/ops_tests.rs#mod validate_warnings_and_connections_tests;)
• e2e — Background work visits every agent scope; find_owner resolves a live agent's job and returns Ok(None) for a missing one.: Exercises the happy and cleanly-missing owner paths; a failed lookup suppressing persistence is not covered end-to-end. (tests/storage_scope_e2e.rs#async fn background_work_visits_every_agent_scope() {)

Findings

• Conclusion: Success

• Lane summary: This increment fixes the earlier critical: the devices bus now consumes `within_agent`'s new optional result and warns on the dropped frame, and `abandon_unpersisted_pairing` is properly tested.

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Positive: The fail-closed semantics are applied consistently: every within_agent caller handles the new None (skip) case, and device owner resolution delegates to the shared decide helper.
• Lane summary: The round-two fail-closed work is largely sound: callers were updated for the new Result/Option shapes, cached owners are re-validated and forgotten when stale, and the unpersisted-pairing abandonment closes the leftover-cipher hole. Three concerns from earlier rounds remain: the cron not-found match is still by error text, the per-scope task-source smoke test still asserts nothing, and the fail-closed persistence skip and revoked-frame drop are still not exercised end to end. (18 earlier finding(s) still open) (1 observation(s) grouped into shared inline comments) _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

e2e

• Conclusion: Neutral
• Scope reviewed: all assigned evidence
• Positive: The new owner-lookup probes are exercised by tests/storage_scope_e2e.rs, which the Rust E2E job runs.
• Lane summary: This revision updates the storage-scope e2e test to the new Result/Option signatures and exercises find_owner's happy path across scopes, but the fail-closed behaviours it introduces (persistence skipped on a failed owner lookup, tunnel frames dropped for revoked devices, per-scope task-source firing) are still reached only by unit tests, and the cron not-found detection still matches error text.

📝 Walkthrough

Walkthrough

Owner lookup now distinguishes missing owners from lookup failures. Scope execution and configuration selection use the relevant agent or live-scope context. Device ownership checks cached associations and revocation. Boot-sweep selection now depends on shared storage.

Changes

Scope-aware ownership and event handling

Layer / File(s)	Summary
Agent context and owner lookup crates/openhuman-core/src/storage/agents.rs, crates/openhuman-core/src/storage/agents_tests.rs, crates/openhuman-rpc/src/server/saas_gateway.rs, tests/storage_scope_e2e.rs	Agent context helpers use the process default context for local scope work. Owner searches return Result values and report lookup failures when no scope matches. Tests cover result selection and context behavior.
Flow owner resolution and execution crates/openhuman-core/src/flows/bus/owner.rs, crates/openhuman-core/src/flows/bus/owner_tests.rs, crates/openhuman-core/src/flows/bus/dedup_commit.rs, crates/openhuman-core/src/flows/bus/run_digest.rs, crates/openhuman-core/src/flows/bus/trigger.rs	Flow owner lookup propagates errors and revalidates cached owners. Flow subscribers use owner-scoped configuration and execution.
Task-source scope configuration crates/openhuman-core/src/integrations/task_sources/bus.rs, crates/openhuman-core/src/integrations/task_sources/bus_tests.rs	Task-source handling loads configuration for each live scope and skips scopes with failed configuration loads or disabled task sources. A smoke test covers connection events.
Device and notification owner handling crates/openhuman-core/src/security/devices/owner.rs, crates/openhuman-core/src/security/devices/owner_tests.rs, crates/openhuman-core/src/security/devices/bus.rs, crates/openhuman-core/src/desktop/notifications/bus.rs, crates/openhuman-core/src/desktop/notifications/bus_tests_2_tests.rs	Device ownership revalidates cached owners and excludes revoked devices. Failed device persistence abandons the pairing. Notification persistence is skipped when owner lookup fails; live broadcast continues.

Boot-sweep scope selection

Layer / File(s)	Summary
Boot-sweep plan and validation crates/openhuman-core/src/flows/ops/run_management.rs, crates/openhuman-core/src/flows/ops_tests.rs	The boot-sweep plan no longer accepts SaaS mode or includes a local-only option. Shared storage selects no sweep; non-shared storage selects every scope.

Merge Risk: ⚪ Minimal · up to 9ab8c

The change makes background work skip events when an owner cannot be resolved, instead of falling back to local. No merge-blocking risk was identified in the supplied context.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 2106d

The change strengthens agent isolation and rejects work when ownership cannot be established. An existing device-enrollment failure can still leave a device authorized before its pairing record is saved. That condition predates this PR; the reviewed changes did not demonstrate increased cross-agent exposure.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The retained path requires an established pairing channel and frames decryptable by its active cipher. Device-controlled method names and parameters then reach core RPC invocation under the pairing owner's context: a named agent or the local owner. The inspected path does not demonstrate an arbitrary cross-agent fallback, but it also does not prove that every downstream method is confined to agent-local assets.

Security Findings and Attack Paths

• observed — The retained authorization finding describes a pre-existing incomplete enrollment transition. The cipher is installed and acknowledged before durable device persistence. Persistence failures leave the active cipher and pending session in place; subsequent owner resolution treats a missing row as not revoked and accepts that session's owner. The base already accepted pending ownership without a durable-row check, and enrollment ordering and RPC dispatch are unchanged. The head narrows other ownership paths, so this finding is recorded as an existing security condition rather than an active PR architecture concern.

Trust Boundaries and Controls

• observed — Failed device-owner lookups and unavailable named-agent contexts drop frames. Cached owners require a live non-revoked row, and fresh resolution refuses an ownerless channel that still has an active cipher. Explicit local revocation removes pending sessions and active ciphers. These controls limit the retained path but do not remove the missing-row exception for active pending sessions.

Resilience and Maintainability Implications

• observed — Owner resolution and context refusal occur before flow settlement executes, containing lookup failures by leaving work unhandled rather than writing under a substitute identity. Shared-storage boot recovery also refrains from terminal transitions that could invalidate another process's live run. Neither behavior establishes a durable replay or recovery guarantee for skipped work.

Hardening Proposals

• proposed — Model enrollment as an explicit bounded transition: retain only handshake authority until durable ownership is established, promote to RPC authority after persistence succeeds, and clear provisional session and cipher state on persistence failure or expiry. This would distinguish a legitimate first-frame race from permanently incomplete enrollment.

Exercise and assert per-scope connection handling.

This test runs without an installed backend, so for_each_live_scope visits only the local scope. It also creates no task-source fixtures and has no assertions. Set up distinct live scopes with enabled and disabled configurations, invoke the subscriber, and assert that only the enabled scope dispatches its source. Synchronize the spawned fetches before checking the result.
