[sbx-mgr] publish the lifecycle under a cleanup behind a switch - #1562
Merging this adds publish_native_lifecycle to /space/etc/sandbox.toml, default false. On, State, Wait, List and ListBuildReferencingSandboxes publish a cleanup-owned row's stored lifecycle (STOPPING, DELETING or SUSPENDING) beside the unchanged cleanup.state, instead of CLEANUP_REQUIRED/CLEANUP_FAILED. Off, they publish what they do today.
Row reads carry the stored lifecycle next to the combined status, from the same statement.
A List row whose other fields don't decode keeps its status and stored lifecycle and publishes its cleanup, as State's degraded rows do.
Sandbox events keep the folded labels; they already carry the cleanup fields.
SPACE_SBXMGR_PUBLISH_NATIVE_LIFECYCLE overrides the file, and the sandbox-manager chart sets it when nativeLifecyclePublication.enabled is on, so turning the switch on or off is a chart change and a restart, not a node image.
With the switch off the published lifecycles are today's. One addition: a List row whose other fields don't decode now also carries its cleanup, as State's degraded rows do.
Wait's timeout message names the status as the response would have published it.
docs/configuration.md documents the key, and that Wait reports a cleanup only once it has failed.
Validation
Tests: native_publication_reaches_wait_list_and_build_references, degraded_state_publishes_the_lifecycle_under_a_cleanup_by_the_switch, native_lifecycle_publication_reports_the_lifecycle_under_a_cleanup, only_native_publication_reports_a_cleanup_row_by_its_stored_lifecycle, an_undecodable_list_row_keeps_its_cleanup_and_lifecycle and only_an_absent_config_uses_defaults, the_environment_overrides_native_lifecycle_publication_only_with_a_flag. The State builder for a row whose fields fail to publish shares published_lifecycle with the others and is covered through it.
Tests cover the published lifecycle with the switch off and on, for normal and degraded rows.
Locally: rustfmt --check on every changed Rust file. Rust was not compiled locally, so CI on this head is the build and test evidence.
Severity and risk
Severity: does not apply.
Risk: none with the switch off. Turning it on changes what every reader of those RPCs sees, so do it only once every running reader decides from cleanup.state; turning it off and restarting sandbox-manager restores today's answers without a binary change. The setting is read at startup.
Rollout
The switch stays off until every reader of State, Wait, List and ListBuildReferencingSandboxes is on this release, including running shim processes, which a binary upgrade alone doesn't replace.
Stack
Part of a stack that moves CleanupRequired and CleanupFailed out of the sandbox lifecycle into their own cleanup state. Merge in order; this PR depends on #1561.
Each PR keeps today's published behaviour; only the last adds a switch, off by default, that publishes the lifecycle under a cleanup.
AI assistance: an AI coding agent drafted the code, tests and this description; the author reviewed them, and a second AI agent reviewed the change. Perplexity Computer rebased the stack, repaired integration conflicts, restored a test assertion in #1553, and updated this disclosure.

Walkthrough
Sandbox storage now keeps combined status separate from stored lifecycle. A default-off setting controls whether cleanup-owned rows publish the stored lifecycle across State, Wait, List, and ListBuildReferencingSandboxes. Cleanup ownership remains reported separately. Undecodable rows can retain and publish separately readable status and lifecycle values.

Merge Risk: Low · previous review 68464
The new lifecycle publication is off by default, so existing behavior is unchanged. Enabling it requires every reader to use cleanup.state first, so owners should follow the documented rollout order.

Derive the expected cleanup ownership without calling cleanup_owner.
The test iterates all SandboxState values, which is good. But owned comes from cleanup_owner, and published_lifecycle uses the same function. If cleanup_owner mapped a state wrongly, for example CleanupFailed to Unspecified, both sides would change together and the test would still pass.
Use an independent oracle instead. For example, set owned = matches!(status, SandboxState::CleanupRequired | SandboxState::CleanupFailed).
As per path instructions: "Flag assertions that cannot fail".

Derive the expected ownership independently in the test loop instead of calling
cleanup_owner: set owned based on whether status is CleanupRequired or
CleanupFailed, while leaving published_lifecycle and the existing assertions
unchanged.
Extend the existing handoff test instead of adding a test with a partial case list.
a_cleanup_row_decodes_its_status_and_the_lifecycle_under_it covers 2 of the CleanupCompletion cases. a_cleanup_handoff_stores_the_teardown_transition_its_intent_names already loops over 5 cases and asserts the stored lifecycle string. MarkCreated, Quarantine, and MarkSuspended therefore have no decoder assertion for row.lifecycle.
Add one assertion inside the existing loop. Compare get_sandbox(...).lifecycle.as_str() with the loop's lifecycle string. Then delete the new test, except for the ordinary Started row check. If you keep the Started check, move it into an existing test.
This follows the policy to prefer extension over addition and to avoid hand-picked subsets of a variant set.
As per path instructions: "Flag ... tests that cover a hand-picked subset of an enum instead of every variant".

Three of the six places that read publish_native_lifecycle have no test:grpc_core.rs:1115 (ListBuildReferencingSandboxes), and both degraded State builders (grpc_state_snapshot.rs:683-694 and :821).
The only tests that turn the switch on cover build_sandbox_info and one undecodable List row.
Forcing the switch to false at each read site, then running the PR's tests: only the build_sandbox_info mutation fails a test. Wait and decoded List fail only a test I added locally. The three sites above fail nothing.
Suggested fix: on/off cases for Wait, decoded List, ListBuildReferencingSandboxes and both degraded State builders. That's the plan's step-4 check that each surface's payload matches §5.
The switch has no shipped way to be set.
sandbox.toml is generated by the image build (infra/space/packer/scripts/base/07-sysctl.sh, which writes only max_memory_mib and hugepages) and by the Kind node layout. The chart mounts /space/etc read-only and says the node image provides it.
Nothing else reads the switch, such as an environment override. So turning it on, or back off, means a new node image and a node roll, or editing files on each host.
That undercuts the plan's promise that "rolling one back doesn't need a binary downgrade". It doesn't block Phase 1 (the switch ships off), but the gate between the phases depends on it.
Suggested fix: an image-build variable, an environment override or a chart value.
Low
proto/sandbox/manager/v1/manager.proto is now partly wrong, and no later PR touches proto:
:769-773 "Published as the CLEANUP_REQUIRED/CLEANUP_FAILED lifecycle" and :738-739 "which nodes keep publishing for these rows" are false with the switch on;
:848-849, SandboxListElement.cleanup "Absent … when the row can't be decoded", is false even with it off, as finding 4 explains.
"Off, they publish what they do today" isn't quite true. With the switch off, an undecodable List row now also carries cleanup (grpc_core.rs:129-134), as an_undecodable_list_row_keeps_its_cleanup_and_lifecycle asserts. It's additive and matches State's degraded rows, but the commit and description should say so.
grpc_pool_wait_clone.rs:765: Wait's timeout message prints state.as_str(), so with the switch on a required row still times out with "(current: cleanup_required)".
Verified against 059d6bb4e5131259449859b2a8468c3ba1f59848.
What I ran:
Wait under both settings:
a deleting + failed row returns CLEANUP_FAILED off and DELETING on, with cleanup FAILED in both, and observed_lifecycle() still decodes it to CleanupFailed;
a required row never completes: with a timeout it returns DeadlineExceeded, and without one it was still waiting after 30 s. So "reports FAILED and never REQUIRED" holds.
List under both settings: CLEANUP_FAILED off, DELETING on, cleanup FAILED in both.
With the switch on and a status label that doesn't parse, both degraded State builders still publish UNSPECIFIED with no cleanup.
The touched store and server tests: 25 of 25 pass.
What I read:
Off by default everywhere: a #[serde(default)] bool, derived Default, a missing file falls back to defaults, test fixtures use ..Default, and there's no deny_unknown_fields, so an older binary ignores the key.
Off is identical:published_lifecycle(false, …) returns the combined status, and every SELECT feeding row_to_sandbox or row_to_list_sandbox now includes state.
Toggling back: the tests flip the switch on one service and get the folded projection back. In production the setting is read at startup, so a flip needs a sandbox-manager restart.
Not run: the shim and API readers with the switch on, or the kind smoke.
State, Wait and List publish a cleanup-owned row's lifecycle as
CLEANUP_REQUIRED or CLEANUP_FAILED, folding the cleanup into it, although
cleanup.state already names the cleanup.
Add publish_native_lifecycle to sandbox.toml, default false, and
SPACE_SBXMGR_PUBLISH_NATIVE_LIFECYCLE to override it, which the
sandbox-manager chart sets when nativeLifecyclePublication.enabled is on.
Both are read at startup. On, those
RPCs publish the lifecycle the cleanup is over (STOPPING, DELETING or
SUSPENDING) beside the unchanged cleanup.state; off, they publish what
they do today. The row reads now carry the stored lifecycle next to the
combined status, from the same statement.
A List row whose other fields don't decode keeps its status and stored
lifecycle, read apart from them, and now also publishes the cleanup that
owns it, as State's degraded rows do. A degraded row whose stored
lifecycle wasn't read publishes UNSPECIFIED rather than a folded label
when the switch is on.
Turn it on only once every reader of those RPCs decides from
cleanup.state; the Rust readers and the shim already do.
