fix(sandbox): carry module config explicitly, recheck a retired slot after cleanup - #8669
Rechecks a retired slot after awaiting an owner's cleanup, so a command that waited while release() or shutdown() retired its slot no longer starts a create.
Makes CleanupTicketpub(super), fixing a private_interfaces clippy error in sandbox/boxes/cleanup.rs that failed clippy-product, embed-clippy and tinyhumans-clippy.
Drops the now-stale CALL_CONFIG record from scripts/ci/process-statics.json.
ModuleConfig(Option<Arc<Config>>) is carried by BoxSettings (create) and BoxExec (exec). BoxBackend::settings(config) fills it; the registry copies it into each BoxExec. BusBoxDriver::config(&ModuleConfig) returns the call's own configuration, and records it as the latest only when its modules are enabled. Close and forget keep using the configuration a box was created under (created_with, from fix(sandbox): scope retained boxes per workspace and deployment, and make the box registry cancellation-safe #8664), falling back to the latest. BusBoxDriver::serve is removed.
resource_for rechecks slot.current()? after settle(); a retired slot returns Released before any create.
Invariants unchanged: the retention key holds only hashes, agent37 boxes are never deleted by the host, OpenShell close behaviour is unchanged, and a failed retained create never falls back to a disposable box.
Submission Checklist
If a section does not apply to this change, mark the item as N/A with a one-line reason. Do not delete items.
Tests added or updated (happy path + at least one failure / edge case): each_call_reaches_the_module_with_its_own_configuration (interleaved calls, fallback to latest), module_config_compares_by_identity_and_never_prints_the_configuration, the agent37 settings test asserting the call's configuration rides with its settings, and a_command_waiting_on_a_cleanup_creates_nothing_once_the_slot_is_retired (failed before the fix with 2 creates).
Diff coverage ≥ 80%: not measured locally; to be ticked once CI's diff-cover reports a figure.
Coverage matrix updated: N/A, behaviour-only change to the sandbox box registry, which has no matrix row.
All affected feature IDs from the matrix are listed in the PR description under ## Related: N/A, no matrix row covers the sandbox box registry.
No new external network dependencies introduced: N/A, tests use the scripted driver only.
Manual smoke checklist updated if this touches release-cut surfaces: N/A, server-side sandbox backend.
Server-side sandbox box registry only. No change to the wire or config surface; BoxSettings and BoxExec gain a module field, and BusBoxDriver::serve is removed (crate-internal use only).
Fixes the agent-runtime-boundary ratchet; the process-statics ratchet drops one record.

Behavior Changes
Intended behavior change: a command whose slot is retired while it waits on an owner's cleanup returns Released instead of creating a box.
User-visible effect: none beyond teardown no longer leaving a fresh allocation behind.
Parity Contract
Legacy behavior preserved: per-call module configuration semantics are unchanged; only how it is carried changes.
Guard/fallback/dispatch parity checks: the existing registry, retention, cleanup and bus-driver tests pass unchanged apart from the two tests adapted from serve to the explicit configuration.
Sandbox operations use the module configuration associated with each call, including its workspace settings. Operations without an explicit configuration use the most recent applicable configuration.
Bug Fixes
Commands waiting for resource cleanup no longer create a replacement resource if the original resource was released or the sandbox shut down.
Resource cleanup continues to use the configuration associated with the resource when it was created.
CI on 891d095 (the later 8e7c9b0 changes one test only), compared with the baseline runs of main
Fixed by this PR: Lanes (checks) (agent-runtime-boundary, process-statics, saas-ambient) and the three clippy steps of rust-lint.
Pre-existing, same as baseline: embed-offline-examples; rust-cov-core (4 of the baseline's 5); rust-cov-facades (6 of 9); rust-cov-product (60 of 61, plus embed::turn_cancellation::cancellation_is_awaited_and_scoped_to_one_turn, which also fails on a clean origin/main checkout locally with the same panic at turn_cancellation.rs:69).
Diff coverage: no diff-cover report was produced because the lanes failed; box left unticked.
…local
Replace the task-local CALL_CONFIG scope with a ModuleConfig handle stored on BoxSettings and BoxExec, so each driver step reads the configuration of the call it belongs to directly rather than relying on the ambient task context. The driver still records the most recent call's config for work outside any call.

BoxSettings and BoxExec now include a module configuration field, and the boxes module re-exports ModuleConfig so callers can build these values. Test fixtures were updated to populate the new field with defaults, and the module docs now point at BoxSettings::module instead of the driver's serve method.

The box driver now takes the module configuration as an explicit argument instead of reading it from shared state, so concurrent calls can no longer observe each other's settings. Tests were reworked to exercise this directly and to cover ModuleConfig identity comparison and redacted debug output.

The process-statics inventory no longer lists the CALL_CONFIG task-local from the sandbox box bus driver, since that entry no longer reflects a static in the codebase.

Add a regression test asserting that a command waiting on an in-flight cleanup fails with Released and never starts a create once shutdown retires its slot.
Auto-committed-on: cuttlefish
Co-authored-by: Medulla <medulla@tinyhumans.ai>
After waiting for pending cleanups to settle, the registry now re-reads the slot and returns the existing resource if one is still present. A release or shutdown could retire the slot during that wait, so this avoids starting a create for a slot that nothing will clean up.

Completeness: Complete Test assessment: Test coverage is assessed from changed tests and lane evidence; execution is not claimed without trusted check data.
What changed
Per-call module configuration no longer lives in ambient task state. `ModuleConfig(Option<Arc<Config>>)` is attached to `BoxSettings` (create path) and `BoxExec` (exec path); `BoxBackend::settings(config)` fills it, and the registry clones it into each `BoxExec`. `BusBoxDriver::config(&ModuleConfig)` returns the call's own configuration, recording it as the latest only when its modules are enabled, and falls back to the latest otherwise; `BusBoxDriver::serve` is removed along with its `CALL_CONFIG` task-local and the process-statics record for it. Close and forget continue to use the configuration a box was created under, falling back to the latest. Separately, `resource_for` rechecks `slot.current()?` after `cleanups.settle(owner).await` and returns `Released` before any create when the slot was retired while waiting. `CleanupTicket` moves from private to `pub(super)` with its fields and `Drop` impl unchanged. The regression test for the retired-slot guard now waits with paused-time sleeps instead of fixed `yield_now` iteration counts.
Features
Added — ModuleConfig carried explicitly on box settings and execs: Each box call reaches the TinyBox module with the configuration of the call it belongs to, without relying on task-local state; concurrent calls keep their own configuration, and work outside any call uses the most recent module-enabled call's. The configuration holds credentials, so its `Debug` prints a placeholder rather than the contents, and equality is by `Arc` identity. (crates/openhuman-core/src/sandbox/boxes/types.rspub struct BoxSettings {, crates/openhuman-core/src/sandbox/boxes/types.rspub struct BoxExec {, crates/openhuman-core/src/sandbox/boxes/types.rsimpl BoxSettings {, crates/openhuman-core/src/sandbox/boxes/mod.rsimpl BoxBackend {, crates/openhuman-core/src/sandbox/boxes/registry.rsimpl<D: BoxDriver> BoxRegistry<D> {)
Internal refactor — BusBoxDriver config lookup by explicit ModuleConfig: `config` selects the call's own configuration when one is supplied and otherwise the latest module-enabled one, updating the latest only for module-enabled calls so a modules-disabled call cannot become the configuration later cleanups use. Create and exec steps pass their settings'/exec's configuration; close and forget keep the created-under configuration. (crates/openhuman-core/src/sandbox/boxes/bus_driver.rsimpl BusBoxDriver {, crates/openhuman-core/src/sandbox/boxes/bus_driver.rsimpl BoxDriver for BusBoxDriver {, crates/openhuman-core/src/sandbox/boxes/bus_driver.rspub(crate) const BUS_REPLY_GRACE: Duration = Duration::from_secs(5);)
Modified — Retired-slot recheck after owner cleanup settles: A command that waited on an owner's in-flight cleanup while `release()` or `shutdown()` retired its slot now gets `Released` before any create, so teardown cannot return with a fresh allocation outstanding. (crates/openhuman-core/src/sandbox/boxes/registry.rsimpl<D: BoxDriver> BoxRegistry<D> {)
Modified — CleanupTicket visibility widened to pub(super): Sibling modules in `sandbox::boxes` can now name the cleanup ticket type; its fields stay private and its pending-count bookkeeping and `Notify` wakeup are unchanged. (crates/openhuman-core/src/sandbox/boxes/cleanup.rsimpl Cleanups {)
Tests
unit — A command waiting on an owner's cleanup during reaping, whose slot is retired by shutdown, returns Released and the driver records no additional create.: Updated so the wait for the spawned tasks relies on paused-time sleep semantics rather than a guessed yield count; it is a test change in the diff, not an execution result. (crates/openhuman-core/src/sandbox/boxes/registry_retain_tests.rsasync fn shutdown_waits_for_a_cleanup_already_in_flight() {, crates/openhuman-core/src/sandbox/boxes/registry_retain_tests.rsfn settings() -> BoxSettings {)
unit — A modules-disabled call keeps its own configuration for its own work while a later cleanup outside any call still uses the enabled configuration.: Covers the guard that only module-enabled calls update the latest configuration. (crates/openhuman-core/src/sandbox/boxes/bus_driver_tests.rsfn a_reservation_kept_after_create_answers_is_not_abandoned() {, crates/openhuman-core/src/sandbox/boxes/bus_driver_tests.rsfn settings() -> BoxSettings {)
unit — ModuleConfig equality is by Arc identity, distinct instances of equal content compare unequal, and Debug output does not contain the configuration's path.: Backs the never-print-the-configuration property for a type that holds credentials. (crates/openhuman-core/src/sandbox/boxes/bus_driver_tests.rsfn an_exec_carries_argv_workdir_and_only_the_given_env() {, crates/openhuman-core/src/sandbox/boxes/types.rsimpl std::fmt::Debug for OwnerScope {)
unit — Agent37 settings carry the call's own configuration alongside the expected limits, workdir and owner scope.: Asserts the call configuration rides with settings on the agent37 path. (crates/openhuman-core/src/sandbox/agent37_tests.rsfn box_settings_come_from_the_agent37_runtime_config() {)
test_fixture_update — Settings fixtures in the box test modules gained a `module: ModuleConfig::default()` field to satisfy the new structure.: Mechanical adaptation for the new field; no behavioral assertion of its own. (crates/openhuman-core/src/sandbox/boxes/mod_tests.rsfn settings_come_from_the_runtime_table() {, crates/openhuman-core/src/sandbox/boxes/registry_tests.rsfn settings() -> BoxSettings {)

Agent review details
critique
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The change adds a `ModuleConfig::default()` field to the test's `BoxSettings` builder and a new paused-time test asserting that a command waiting on a cleanup returns `BoxError::Released` and does not create a box after shutdown retires its slot. The new test's synchronization (a `yield_now` loop on `driver.forgotten()` plus paused-time sleeps) is sound, and the assertion on `driver.created() == 1` matches the fixture's create accounting. I found no defect in this file. _The code index is behind this pull request (indexed at `4f72a19b3f18`), so retrieved context may be out of date._
security
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: The security lane answered with no findings; notably, the new configuration carrier redacts the configuration (which holds credentials) from its Debug output, and the new test uses the scripted driver only.
Lane summary: This is a test-only change: it adds a `ModuleConfig::default()` field to the test's `BoxSettings` fixture and one new tokio test exercising the registry's shutdown/cleanup race. No production code, no untrusted input, no new network or subprocess calls. The new test follows the repository's sibling-test-file convention and uses the scripted driver, so it makes no real backend calls. Nothing reportable. _The code index is behind this pull request (indexed at `4f72a19b3f18`), so retrieved context may be out of date._
tests
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The new test `a_command_waiting_on_a_cleanup_creates_nothing_once_the_slot_is_retired` pins the new `slot.current()?` guard in `resource_for` (it asserts `BoxError::Released` and `driver.created() == 1`), and the rewritten `each_call_reaches_the_module_with_its_own_configuration` plus the new `module_config_compares_by_identity_and_never_prints_the_configuration` cover the `ModuleConfig` identity/Debug contract. I found no defect in the changed code or its tests. _The code index is behind this pull request (indexed at `4f72a19b3f18`), so retrieved context may be out of date._

description
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: The description lane answered with no findings, finding the new regression test, the `module` fixture field and the dropped `CALL_CONFIG` record consistent with the description.
Lane summary: The new commits add a regression test for the retired-slot recheck, a `module` field to the retain-test settings fixture, and drop the stale `CALL_CONFIG` record from process-statics.json — all consistent with the PR description.

Walkthrough
Sandbox calls now carry module configuration through box settings and execution requests. The driver selects configuration per operation without task-local state. The registry rechecks slots after pending cleanup and returns a release error when shutdown retires a waiting slot.

Summary
Module configuration contract and wiring crates/openhuman-core/src/sandbox/boxes/types.rs, crates/openhuman-core/src/sandbox/boxes/mod.rs, crates/openhuman-core/src/sandbox/boxes/mod_tests.rs, crates/openhuman-core/src/sandbox/agent37_tests.rs
Adds ModuleConfig to BoxSettings and BoxExec. Settings construction and command, read, and write operations use the new configuration field. The Agent37 test checks that its workspace directory matches the call configuration.
The driver selects configuration from BoxSettings::module or BoxExec::module. Calls without configuration use the latest module-enabled configuration; cleanup uses the creation configuration. Tests replace serve checks with direct configuration assertions. The CI statics entry for CALL_CONFIG is removed.
Registry execution and cleanup race crates/openhuman-core/src/sandbox/boxes/registry.rs, crates/openhuman-core/src/sandbox/boxes/registry_retain_tests.rs, crates/openhuman-core/src/sandbox/boxes/registry_tests.rs, crates/openhuman-core/src/sandbox/boxes/cleanup.rs
The registry copies settings.module into BoxExec and rechecks a slot after owner cleanup. A test verifies that shutdown retires a waiting slot and prevents creation of a replacement box. CleanupTicket is now visible to its parent module.
tinyhumansai/openhuman#8545: Introduced the Agent37 sandbox backend and its BoxSettings construction, which this change extends with ModuleConfig.
tinyhumansai/openhuman#8664: Changed BusBoxDriver and BoxRegistry for per-call configuration and cleanup; this change adds explicit module configuration and a retired-slot recheck.

What changed in this PR
This follow-up to #8664 replaces task-local sandbox configuration with explicit per-call configuration and prevents commands waiting on cleanup from creating a box after their slot is retired.
Changes:
Carries module configuration through BoxSettings and BoxExec, preserving configuration-safe cleanup and redacted debug output.
Rechecks slot retirement after cleanup completes, with a regression test for shutdown during the wait.
Updates configuration tests and removes the obsolete CALL_CONFIG process-statics record.
207-207: Trivial · Maintainability & Code Quality · Heavy lift
Cover configuration selection through create and exec.
This test calls driver.config directly. It can pass if BusBoxDriver::create or BusBoxDriver::exec selects the wrong module configuration. Add an operation-level test with mocked TinyBox calls or a recording transport in BusBoxDriver. Interleave calls with distinct configurations and assert the configuration each operation uses.

… test
The test now waits for spawned tasks by sleeping under paused time instead of yielding a fixed number of times, since the clock only advances once every other task is blocked. This removes the guesswork around yield counts and makes the synchronization deterministic.
