[proto] publish whether a node-local cleanup owns a sandbox row - #1554
Merging this adds wire fields that let sandbox-manager publish whether a node-local cleanup owns a row, apart from its lifecycle:
SandboxCleanupState (UNSPECIFIED, REQUIRED, FAILED) as field 2 of SandboxCleanup;
optional SandboxCleanup cleanup on WaitResponse (field 4) and SandboxListElement (field 10).
The comments describe the finished contract: nodes publish these rows as CLEANUP_* by default and as the teardown transition with native publication on (#1562), and Wait reports a cleanup only once it has failed.
The fields are additive and empty here; the next PRs fill them. Sandbox-manager keeps publishing CLEANUP_REQUIRED and CLEANUP_FAILED lifecycles, and readers must keep honoring them because an older node never sets the new field. UNSPECIFIED means no cleanup owns the row, which also covers an armed activation whose rollback target is in completion, so readers test state, not the message's presence.
shim/proto is regenerated with the pinned protoc 35.0 and protoc-gen-go v1.36.11.
Validation
Locally: rustfmt --check on every changed Rust file, plus gofmt -l, go vet and go test for the shim. 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 at runtime; the fields stay empty. Roll back by reverting.
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 #1553.
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.

No actionable comments were generated in the recent review.
Walkthrough
The protobuf schema adds SandboxCleanupState and optional cleanup fields to SandboxListElement and WaitResponse. Server response construction initializes cleanup to absent or sets its state to Unspecified. The lifecycle test fixture also initializes cleanup to absent.

- Line 2068: Update cleanup_to_proto to derive SandboxCleanupState as REQUIRED

cleanup_completion is present, reserving UNSPECIFIED for rows without a cleanup
owner or with non-cleanup lifecycles such as armed activation. Preserve the
existing lifecycle fallback for older nodes.

proto/sandbox/manager/v1/manager.proto:768-774: the new enum comments go stale later in the stack, and nothing later updates them.
The enum values say REQUIRED and FAILED are "Published as the CLEANUP_REQUIRED/CLEANUP_FAILED lifecycle". The state field comment (:739) says "which nodes keep publishing for these rows".
What 1562 changes: with publish_native_lifecycle = true, a node publishes STOPPING/DELETING/SUSPENDING instead, as that PR's docs/configuration.md hunk says. No later PR in the stack touches proto/ or shim/proto (git diff --stat for 1555 through 1562 is empty), so the wire contract's own comments become wrong for any node with the switch on.
The message-level comment (:721, from 1501) goes stale too. It says a cleanup row "can also have none", but from 1556 on, cleanup_observation(cleanup_owner(..), completion) always builds the message for an owning cleanup.
Wait's narrower contract isn't in the WaitResponse.cleanup comment either. 1562's docs say Wait "reports FAILED and never REQUIRED".
Saying "published as CLEANUP_REQUIRED unless the node publishes the native lifecycle" here, or updating these comments in 1562 next to the switch, would keep the proto accurate.
WaitResponse.cleanup and SandboxListElement.cleanup: their comments say "Absent when none is recorded, or from an older node". At this head, though, both builders hard-code cleanup: None (crates/l40_api/sbx/mgr/server/src/service/grpc_pool_wait_clone.rs:746, grpc_core.rs:40), so a node built here sends no message for rows that do have a recorded cleanup. That's harmless only because readers keep deciding from the CLEANUP_* lifecycles until 1557, and 1556 fills the fields. It's fine if the stack lands together. If it might not, "set by nodes that publish cleanup state" would avoid implying that absent means none.
Verified against e02da7060655a26464056fc219e3e3fbef76d3b8.
What I ran:
cargo nextest run -p pplx-space-sbx-mgr-protocol --all-features: 13 of 13 pass.
cargo check --tests for sbx-mgr, template-mgr and sbx-mgr-cli: clean. This covers every other WaitResponse and SandboxListElement literal in the workspace.
In shim/, go vet ./proto/... and go test ./...: pass.
A protoc --encode/--decode round trip:
a new-proto WaitResponse carrying cleanup decodes under the base proto with field 4 as unknown;
an old CLEANUP_FAILED response decodes cleanly under the new proto;
SandboxListElement's cleanup arrives as unknown field 10.
What I read:
The new field numbers (2, 4, 10) are fresh.
The enum's zero value means "no cleanup owns the row".
The field comment tells readers to test state, not the message's presence.
The 690 deleted lines are all regenerated Go. The exported symbols of manager.pb.go before and after differ only by additions.
I didn't regenerate the Go code myself: my local protoc isn't the pinned version, so I relied on CI's stale-generation check, which passes on this head.
Thanks @the-gigi-pplx. Rebased the stack on main (47f3aa39); this PR's head is now 5359f741be88.
1 and 2. Proto comments. Agreed. The comments now describe the finished contract rather than this PR's moment:
the enum values say "published as CLEANUP_* unless the node publishes the native lifecycle";
state names the native-lifecycle case;
the message comment says a node that sets state publishes an intent-less cleanup with completion = UNSPECIFIED, and an older node publishes nothing;
WaitResponse.cleanup says Wait reports a cleanup only once it has FAILED;
both new cleanup fields say "absent when none is recorded, or from a node that doesn't publish it".
manager.pb.go is regenerated with the pinned protoc 35.0 / protoc-gen-go v1.36.11. The stack is meant to land together, but the wording no longer depends on that.
Add `SandboxCleanupState` (`UNSPECIFIED`, `REQUIRED`, `FAILED`) as field 2
of `SandboxCleanup`, and `optional SandboxCleanup cleanup` to
`WaitResponse` (field 4) and `SandboxListElement` (field 10), so each
surface that publishes a lifecycle can also publish the cleanup state from
the same row read.
This is the wire half of moving `CleanupRequired` and `CleanupFailed` out of
the sandbox lifecycle into their own cleanup state. The fields are
additive: sandbox-manager keeps publishing the `CLEANUP_REQUIRED` and
`CLEANUP_FAILED` lifecycles for these rows, and readers must keep honoring
them, because an older node never sets the new field. `UNSPECIFIED` means no
cleanup owns the row, which also covers an armed activation whose rollback
target is published in `completion`; readers test `state`, not the
message's presence.
The fields are left empty here and filled by the sandbox-manager change
that introduces the cleanup state. `shim/proto` is regenerated with the
pinned protoc 35.0 and protoc-gen-go v1.36.11.
