[sbx-mgr-protocol] decode an owning cleanup to its combined status - #1558
Merging this makes observed_lifecycle() on SandboxInfo, SandboxListElement and WaitResponse fold cleanup.state into the status a reader decides from: a REQUIRED or FAILED cleanup decodes to CleanupRequired or CleanupFailed whatever lifecycle is reported. An unknown cleanup state fails closed, as an unknown lifecycle does; an armed activation keeps its reported lifecycle.
The Rust readers whose answers depend on a cleanup go through this method: Direct's adoption and source cleanup, the API's substrate probes and responses, template-manager, and node-ctl, whose publication feeds internal-api ingest and the UI. So they keep their answers when a node later reports the teardown transition instead. Two Direct helpers, resident_is_dormant and refuse_wake_denied_by_local_override, still decode lifecycle themselves; they match only Created, Stopped, Paused and Suspended, which no cleanup-owned row reports, so their answers don't change.
Every combination of owning cleanup state and reported lifecycle decodes to the combined status on all three messages; an armed completion leaves the lifecycle alone; an unknown cleanup state is an error.
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 while nodes publish CLEANUP_*. 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 #1557.
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
SandboxInfo, SandboxListElement, and WaitResponse now decode lifecycle observations with optional cleanup state. Required and failed cleanup map to CleanupRequired and CleanupFailed. Absent or unspecified cleanup preserves the decoded lifecycle. Unknown cleanup values return UnknownCleanupState. Tests cover these cases.

Merge Risk: Low · up to 8c078
This changes how cleanup status is decoded for several Rust services and is covered by tests. No defects were found in the review, so owners should simply be aware that shared decoding behavior changed.

Sweep every valid lifecycle in the owning-cleanup test.
The loop at lines 57-62 checks only four reported lifecycles. It omits the other valid values, including Started, and it omits CleanupFailed as a reported lifecycle for a Required owner. A change that applies the owning-cleanup override only to some lifecycles would still pass.
Build the lifecycle list from an exhaustive match over SandboxLifecycleState, as label() does in lifecycle.rs. Adding a variant then fails the build until the sweep covers it. Assert the combined status for every valid variant.
Keep Unspecified out of that sweep. decode_lifecycle rejects it before cleanup is read, so an owning cleanup on an Unspecified lifecycle returns UnknownValue(0). Assert that result in a separate check.

crates/l40_api/api/src/controllers/substrate/direct.rs:541-552 and :597-609: resident_is_dormant and refuse_wake_denied_by_local_override still decode record.lifecycle themselves with SandboxLifecycleState::try_from, which contradicts "every Rust reader goes through this method". Their answers don't change: they match only Created, Stopped, Paused and Suspended, and the I1 triggers allow a cleanup state only on stopping, deleting or suspending. Moving both to observed_lifecycle() would keep the claim true, or the claim could be narrowed.
Verified against bf44013d1c423bb9e2e1745222f06178fe18adeb.
What I ran:
cargo nextest run -p pplx-space-sbx-mgr-protocol --all-features: 14 of 14 pass.
Mutations, each caught by a test:
an unknown cleanup value treated as no cleanup;
UNSPECIFIED treated as owning;
FAILED mapped to CleanupRequired;
WaitResponse and SandboxListElement each reverted to the old decode;
an absent message treated as an error.
What I read:
Every (lifecycle, cleanup state) combination decodes to today's answer on all three messages. No message, or UNSPECIFIED with a completion, keeps the lifecycle. An unknown value is an error.
The Direct callers' answers are unchanged for today's rows: lifecycle_holds_live_runtime, the adoption gate, the source-deletion arm (where an Err keeps the copy) and route catch-up. node-ctl's readers still treat an Err as unknown.
Note: the Go shim reader in 1557 treats an unknown cleanup value as owning, the opposite of this decode. That's the finding on 1557.
Thanks @the-gigi-pplx. Rebased the stack on main (47f3aa39); this PR's head is now 31365e1701d8.
Agreed. I narrowed the claim in the description and the commit message rather than moving the two helpers. They now say the readers whose answers depend on a cleanup go through observed_lifecycle(), and name resident_is_dormant and refuse_wake_denied_by_local_override as decoding lifecycle themselves, with unchanged answers because no cleanup-owned row reports Created, Stopped, Paused or Suspended.
`observed_lifecycle()` on `SandboxInfo`, `SandboxListElement` and
`WaitResponse` now folds `cleanup.state` into the status a reader decides
from: a `REQUIRED` or `FAILED` cleanup decodes to `CleanupRequired` or
`CleanupFailed` whatever teardown transition the lifecycle reports. A
cleanup state this build doesn't know fails closed, as an unknown lifecycle
does. An armed activation, whose cleanup carries only a completion, keeps
its reported lifecycle.
Nodes still publish these rows as `CLEANUP_REQUIRED`/`CLEANUP_FAILED`, so
nothing changes yet. The Rust readers whose answers depend on a cleanup go
through this method: Direct's adoption and source cleanup, the API's substrate probes and
responses, template-manager, and node-ctl, whose publication feeds
internal-api ingest and the UI. A later node that reports the transition
instead therefore gets the same answers from all of them.
Tests: every combination of owning cleanup state and reported lifecycle
decodes to the combined status on all three messages; an armed completion
leaves the lifecycle alone, and an unknown cleanup state is an error.
