[sbx-mgr] retire the CLEANUP_* lifecycle values and the fold that read them - #1713
Merging this retires the CLEANUP_REQUIRED and CLEANUP_FAILED lifecycle values and everything that still read them. It finishes the cleanup-state work: the cleanup that owns a row is no longer a sandbox lifecycle anywhere, whether in storage (#1710), in sbx-mgr's types (#1711), on the wire, or in readers.
Protocol fold.observed_lifecycle() folded cleanup.state back into the combined values. It is replaced by observed_status(), which returns an ObservedStatus (crates/l20_domain/sbx/mgr/protocol/src/lifecycle.rs). Like sandbox manager's SandboxStatus ([sbx-mgr] keep CleanupRequired and CleanupFailed out of SandboxState #1711), it is Unowned(lifecycle) or Owned { teardown, cleanup }, and a cleanup over a lifecycle no cleanup can be over fails to decode. A status doesn't compare equal to a lifecycle: readers ask is_unowned() or match on unowned(), so the API, node-ctl, template-manager and the CLIs give a cleanup-owned row the same answer as before.
Control-plane label unchanged.ObservedStatus::label() still names a cleanup-owned row cleanup_required or cleanup_failed. The status node-ctl publishes, which the API renders and probes, doesn't change.
Shim. It decides cleanup ownership from cleanup.state alone (shim/space.go).
Metric.sandbox.worker.lifecycle.count, which folded cleanups into its state tag, is retired. sandbox.worker.lifecycle.status_count gains its runtime and runtime_version tags, and one store count (sandbox_status_counts) now serves it. docs/observability.md shows the per-version query against the new metric.
Admin list. It no longer accepts lifecycle=cleanup_required, which matched no row and was kept for one release. The console never sends it.
legacy_state.20261109120000_drop_sandbox_legacy_state drops the generated column. [sbx-mgr] decide from state and cleanup_state, and stop reading legacy_state #1710 stopped reading it and kept it one release so a predecessor could still read its database: the contract half of that expand/contract. The snapshot fixture and the store rule stop mentioning it.
Docs. The fold-era upgrade note in docs/configuration.md is replaced by the rollback constraint below.
Kept on purpose: the legacy label still appears where something outside sbx-mgr stores or reads it. That covers the entered_from_state a quarantine or cleanup episode records, the not-running error marker, the net-gateway inventory metric's lifecycle tag, and startup recovery's persisted reason text.
Validation
go test ./... in shim/ passes locally. The cleanup-owned teardown tests now publish the native form: a STOPPING, DELETING or SUSPENDING lifecycle with cleanup.state.
an_owning_cleanup_is_observed_beside_its_lifecycle_and_passes_no_lifecycle_check (protocol) and a_cleanup_owned_row_publishes_its_cleanup_status (node-ctl) pin the reader rule and the published label.
status_buckets_name_the_cleanup_state_and_runtime_and_zero_a_disappeared_series_once and the store's status-count tests cover the merged metric.
Locally on macOS at this tree (rebased onto main unchanged):
cargo test passes for the store (695), the server (1,759), template-manager (418), node-ctl (103), the sbx-mgr CLI (21), the node-API simulator (31) and the protocol crate (14).
Clippy with --all-targets --all-features -D warnings is clean for every crate this PR touches.
go test in shim/ passes.
Go protos regenerated with the pinned protoc.
the_migration_round_trips_every_cleanup_shape_and_keeps_historical_labels runs the new drop's down and up migrations around the others.
CI on this head is the Linux evidence.
Severity and risk
Severity: does not apply; this retires compatibility paths.
Risk:
Retired values. A sandbox manager that still publishes 15 or 16 would have its rows read as unknown: degraded in node-ctl's publication, refused by the shim, inconclusive in the API's probes. That is why this waits for [sbx-mgr] publish the lifecycle under a cleanup unconditionally #1709 to be the rollback floor.
Metric. Dashboards or monitors on sandbox.worker.lifecycle.count go blank and must move to status_count first.
Rollback. Sandbox manager refuses a database whose applied migrations it doesn't bundle (validate_public_history), so reverting this PR alone doesn't roll a node back. Run this image's down migration, which adds the generated legacy_state back and loses no data, before deploying the previous image.
Rollout
Merge once #1709, #1710 and #1711 are deployed everywhere and are the rollback floor, and dashboards and monitors query sandbox.worker.lifecycle.status_count. Readers and sandbox manager can then deploy in any order. After that, sandbox manager must not roll back to a release before #1709.
Stack

Walkthrough
The change separates cleanup ownership from sandbox lifecycle states. It adds structured observed statuses and updates lifecycle readers, action checks, and shim cleanup handling to use them. Storage counts and worker metrics now group by cleanup state alongside lifecycle and runtime identity. The change retires cleanup-specific lifecycle values in the protocol and admin filter, and updates related tests, migrations, and documentation.
Possibly related issues
perplexityai/SPACE#835: The issue describes lifecycle cleanup_required being treated as running in the ECW list. This change retires that lifecycle value and updates cleanup-aware readers, but the reviewed changes do not include the ECW list paging path.
Possibly related PRs

docs/configuration.md:144 — The new rollback note doesn't say that rolling sandbox manager back past this image needs the down migration first.
It says not to roll back to a release that can publish 15 or 16, but the previous image (which can't) still refuses the database: validate_public_history (crates/l10_foundation/sqlite/src/lib.rs:211) rejects the applied, unbundled 20261109120000_drop_sandbox_legacy_state. The PR body's Risk section covers this; the maintained doc doesn't. One sentence there, saying to run this image's down migration before deploying the previous one, would cover it.
docs/observability.md:1247 — The doc doesn't say how to translate a query on the retired metric. status_count{state:stopping|deleting|suspending} also counts cleanup-owned rows, which lifecycle.count reported as state:cleanup_required / state:cleanup_failed. A monitor moved by renaming the metric alone starts counting failed cleanups as in-flight stops, and a state:cleanup_failed filter matches nothing. Two example mappings would close it: lifecycle.count{state:stopping} → status_count{state:stopping,cleanup_state:none}, and {state:cleanup_failed} → {cleanup_state:failed}.
crates/l20_domain/sbx/mgr/protocol/src/lifecycle.rs:92 — Teardown and ObservedStatus mirror the store's Teardown and SandboxStatus (crates/l30_storage/sbx/mgr/store/src/state.rs:498, :543), and ObservedStatus::label repeats SandboxStatus::legacy_label (state.rs:738).
The two sit at different layers (wire enum vs stored lifecycle), so the split is defensible. But no test pins the writer's teardown set to the reader's: if a teardown transition is added to the store's Teardown and not the protocol's, sandbox manager publishes a shape its own readers reject with CleanupOutsideTeardown. A small test in the sbx-mgr server that maps each store Teardown through publication and decodes it with observed_status() would catch that drift.
shim/space.go:1144 — cleanupOwned still treats any known cleanup state as ownership whatever the lifecycle, while the Rust readers now fail closed on a cleanup over a non-teardown lifecycle.
This was the case on main too, and the store's SandboxStatus type means sandbox manager can't publish that shape, so it's unreachable today. It's only a parity gap with the rule this PR adds: on such a row the shim's MARK_SUSPENDED path releases the task without Stop/Delete, while node-ctl marks the row degraded. Returning FailedPrecondition there when the lifecycle isn't STOPPING, DELETING or SUSPENDING would match the Rust readers.
Verified against 3e6f823633a625ee336dba3b1954fcb4f6af8d9f. What I ran: the protocol crate's tests (14 pass), and a mutation that made decode_status accept a cleanup over STARTED, which an_owning_cleanup_is_observed_beside_its_lifecycle_and_passes_no_lifecycle_check caught. I also ran go test ./... in shim/ (passes) and an in-memory SQLite apply of every migration with a down/up round trip of the new drop (legacy_state comes back and goes away again). I checked the repository for other consumers of sandbox.worker.lifecycle.count; only OTLP sink tests use the name, as a fixture string. I read the rest without running it: the reader call sites in the API, node-ctl, template-manager and the CLIs. I didn't run the full workspace tests (CI's Rust tests and Kind smoke were still running when I posted this).
@the-gigi-pplx thanks, all four are fixed in 3d3a31495a8a.
Rollback note.docs/configuration.md now says that rolling sandbox manager back past this release needs this image's down migrations run first, because a release refuses a database whose applied migrations it doesn't bundle.
Query translation.docs/observability.md now warns that renaming the metric alone doesn't translate a query, and gives your two mappings: lifecycle.count{state:stopping} → status_count{state:stopping,cleanup_state:none}, and {state:cleanup_failed} → {cleanup_state:failed}.
Teardown drift.build_sandbox_info_publishes_the_failed_cleanup_completion already publishes every SandboxStatus through build_sandbox_info. It now also decodes each published row with observed_status(), which must succeed with label() == legacy_label() and the same cleanup ownership. An exhaustive match over the store's Teardown stops compiling when a variant is added. As a mutation check, dropping Suspending from the protocol's Teardown::of fails it with "sandbox cleanup over lifecycle Suspending, which no cleanup can be over".
Shim parity.cleanupOwned now takes the lifecycle and returns FailedPrecondition for a cleanup over anything but STOPPING, DELETING or SUSPENDING. TestLegacyTeardownDecidesAnOwnedCleanupByItsCleanupStateNotItsLifecycle covers started, stopped and suspended rows with a failed MARK_SUSPENDED cleanup, for both Kill and Delete.
Locally on macOS: the shim's go test passes, the changed server test passes, and clippy on sbx-mgr is clean.
16303-16303: Trivial · Maintainability & Code Quality · Low value
Strengthen the teardown coverage check.
If a new Teardown variant is added, updating the match does not add it to the array. The test can then miss an omitted cleanup-owned status. The guard also does not check Required.
Use an enum-derived iterator over Teardown and check both cleanup states. SandboxState::all() and Teardown::of do not guarantee that the sweep includes a new teardown.

…d them
Sandbox manager publishes a cleanup-owned row under the teardown transition
it is over (STOPPING, DELETING or SUSPENDING) with `cleanup.state` beside
it. Readers still accepted the retired CLEANUP_REQUIRED and CLEANUP_FAILED
lifecycle values, and the protocol crate folded `cleanup.state` back into
them, so every reader still decided from a combined status. Once no
sandbox manager in service or in the rollback window publishes those
values, both can go.
- Reserve SandboxLifecycleState 15 and 16. A reader now treats them as
unknown and fails closed, the shim included.
- Replace the fold with `ObservedStatus`, `Unowned(lifecycle)` or
`Owned { teardown, cleanup }`, as sandbox manager's `SandboxStatus` is.
`observed_lifecycle()` becomes `observed_status()`, and a cleanup over a
lifecycle no cleanup can be over fails to decode. A status doesn't
compare equal to a lifecycle: readers ask `is_unowned()` or match on
`unowned()`, so every decision is unchanged. `label()` still names a
cleanup-owned row `cleanup_required` or `cleanup_failed`, so the status
node-ctl publishes to the control plane doesn't change.
- The shim decides cleanup ownership from `cleanup.state` alone.
- Retire `sandbox.worker.lifecycle.count`, which folded cleanups into its
`state` tag. `sandbox.worker.lifecycle.status_count` gains its
`runtime` and `runtime_version` tags, and one store count serves it.
- The admin sandbox list no longer accepts `lifecycle=cleanup_required`.
- Drop the generated `legacy_state` column, which nothing has read since
#1710, in a migration of its own (expand/contract).
- Drop the upgrade-order note for fold-era publishers, and record that
sandbox manager must not roll back to a release that can publish the
retired values.
Merge once #1709, #1710 and #1711 are deployed everywhere and are the
rollback floor, and dashboards and monitors query `status_count`.
AI assistance: an AI coding agent drafted this change; I reviewed it.
On the teardown-coverage nitpick in build_sandbox_info_publishes_the_failed_cleanup_completion: the guard now checks both Required and Failed for each teardown (318a5d96f9fb). I kept the explicit list. A new Teardown variant fails the exhaustive match at compile time, which sends whoever adds it to this list. The workspace has no enum-iteration derive (see SandboxLifecycle::all()), so a derived iterator would mean adding one for this test.
…that read them (perplexityai#1713)" (perplexityai#1780)
This reverts commit 13c4c62, except for its
migration. 20261109120000_drop_sandbox_legacy_state stays bundled because
testing has applied it, and a release refuses a database with an applied
migration it doesn't bundle. A new migration,
20261113190000_restore_sandbox_legacy_state, re-adds the generated
legacy_state column with the definition from the drop's down migration.
Prod still runs a release that reads legacy_state, and perplexityai#1713's rollout
contract requires perplexityai#1709/perplexityai#1710/perplexityai#1711 everywhere first. Re-land the
retirement once they are.
