Summary

Reverts the code of #1713, which retired the CLEANUP_* lifecycle values and the fold that read them, but keeps the legacy_state column that #1713 dropped. #1713's rollout requires #1709, #1710 and #1711 to run on every node, and to be the rollback target, before the retirement ships. Releases older than those still read legacy_state and still publish CLEANUP_REQUIRED/CLEANUP_FAILED, so a release that contains #1713 can't yet roll out over them, or roll back to them, safely.

• Restores SandboxLifecycleState CLEANUP_REQUIRED/CLEANUP_FAILED (15/16) in the proto, the protocol crate's fold, their API, node-ctl, template-manager and CLI readers, and the shim's handling of them.
• Restores the sandbox.worker.lifecycle.count gauge next to sandbox.worker.lifecycle.status_count, because dashboards and monitors outside this repository still read it.
• Keeps db/sandbox-manager/20261109120000_drop_sandbox_legacy_state bundled and adds db/sandbox-manager/20261113190000_restore_sandbox_legacy_state. The new migration re-adds the generated legacy_state column with the same statement as the drop's down migration.
• Drops the tests [sbx-mgr] retire the CLEANUP_* lifecycle values and the fold that read them #1713 added for the retired behavior: a_cleanup_owned_row_publishes_its_cleanup_status in node-ctl and the shim's FailedPrecondition case for a cleanup over a started, stopped or suspended lifecycle. They come back when [sbx-mgr] retire the CLEANUP_* lifecycle values and the fold that read them #1713 re-lands.

This isn't a literal revert. A node that already ran a release with #1713 has applied 20261109120000, and sandbox-manager refuses a database with an applied migration its binary doesn't bundle ("unbundled migration" in crates/l10_foundation/sqlite/src/lib.rs). So the drop stays, and a forward migration restores the column.

legacy_state is a VIRTUAL generated column computed from state and cleanup_state, so dropping and re-adding it changes no stored data.

Validation

• CI on this head, including Pull CI's Kind/Firecracker smoke.
• Apart from the parts listed above, the code matches git revert 13c4c62ca on main. Two files conflicted and are resolved onto later changes: store/src/db/tests/cleanup_state_split.rs (suspend: recover the admitted capture from a producer-owned receipt #1763) and sbx/mgr/server/src/metrics/sandbox/worker/inventory.rs (types: import moved types from their own crates, not common-core re-exports #1704).
• cleanup_state_split.rs round-trips the cleanup-state split through the drop and the restore. The suspend_attempt rollback test in db/migrate first steps back past the new migration.
• Not validated: a rolling sandbox-manager upgrade on a real cluster.

Severity and risk

Severity: medium. Without this, the next release can't roll out over, or roll back to, a release from before #1709.

Risk:

• During a roll, a node that hasn't applied 20261109120000 applies the drop, 20261112160000_suspend_attempt and the restore in one up run. An older sandbox-manager still running on that node can fail a query that reads legacy_state while that run is between the drop and the restore. Those queries are on the stop, delete, cleanup and auto-lifecycle paths, which retry.
• Rolling sandbox-manager back past this release still needs this image's down migrations first, newest first. 20261113190000's down drops the column, and 20261109120000's down re-adds it.

Rollout

Re-land #1713 once #1709, #1710 and #1711 run on every node and are the rollback target, with a new migration that drops legacy_state.

Not covered

• sandbox.worker.lifecycle.count emits one sample per stored lifecycle, cleanup state and runtime. Cleanup-owned rows whose lifecycles differ share one cleanup_required or cleanup_failed series, so that series can under-report. This is the code from before [sbx-mgr] retire the CLEANUP_* lifecycle values and the fold that read them #1713, and the gauge goes away again when [sbx-mgr] retire the CLEANUP_* lifecycle values and the fold that read them #1713 re-lands.

AI assistance: Perplexity Computer drafted the code, the restore migration and the first description. Claude Code reviewed them against git revert 13c4c62ca and rewrote this description.

[ac-pplx]

@zibi-pplx heads-up: this reverts your #1713 for the next deploy, because the release it replaces still reads legacy_state. The plan is to re-land it in the deploy after, once #1709, #1710 and #1711 run on every node.

Walkthrough

The protocol adds CLEANUP_REQUIRED and CLEANUP_FAILED lifecycle values and maps cleanup observations to them. Lifecycle accessors and their API, node, template, and CLI consumers now use observed_lifecycle(). Storage adds separate lifecycle and status count queries. The metrics sampler emits both count types, and the database migration restores the generated legacy_state column.

Merge Risk: High · up to 0d19a

This revert restores cleanup lifecycle values and the legacy_state column so production code that still reads them keeps working. Cross-node restore cleanup could delete a source copy that still holds live state when its row is cleanup-owned. A lifecycle gauge can also under-report counts. Reassigning the reserved protobuf values and applying both migrations require rollout ordering, so resolve the cleanup-delete concern and confirm the rollout order before merging.

Security architecture risk: Minimal · up to 0d19a

The inspected changes restore compatibility without establishing an introduced security, failure-containment, or ownership regression. Restoring the legacy database view does not, by itself, make rollback to every older release safe.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — A security-relevant downstream outcome is deletion of a source-node sandbox copy after cross-node restore. The inspected path is scoped to a sandbox and resolved source node, retains unreadable or undecodable observations and records read as live, and skips deletion when restore-lease renewal fails. These controls remain around the changed lifecycle classification.

Trust Boundaries and Controls

• inferred — The fold broadens accepted observation shapes but does not make cleanup-owned rows satisfy the inspected positive lifecycle gates. A malformed known lifecycle paired with cleanup ownership is no longer rejected solely for being outside teardown; existing database triggers reject that persisted combination. No attacker-controlled route to manufacturing such observations was established, and wire-producer coverage is incomplete.

Resilience and Maintainability Implications

• observed — The inspected cleanup ownership machinery is unchanged by the comparison. Requests atomically bind lifecycle and cleanup ownership to an episode; recovery selects persisted requested or cleanup-owned work; finalization checks episode identity and commits the terminal state with job completion. Failed durable attempts retain a persisted retry path. These mechanisms do not depend on the changed public observation wrapper.

Full details: Title check

Explanation

The title names the area (sbx-mgr) and the main change (reverting the CLEANUP_* lifecycle retirement and restoring legacy_state), which matches the objectives and the changeset. It uses the required lowercase area prefix with a colon, starts the summary with a lowercase word, and has no trailing period or ticket ID. The code identifiers keep their case.

Full details: Description Follows The Pr Template

Explanation

The provider-reported PR is #1780 (author ac-pplx). The check tests only the PR description's presence of four items. The current description has all four, each with real content: 1. "## Summary": present. It states that the PR reverts the code of #1713, keeps the legacy_state drop migration, and adds the restore migration 20261113190000. 2. "## Validation": present. It says "CI on this head, including Pull CI's Kind/Firecracker smoke." It also lists the cleanup_state_split.rs and db/migrate checks and the unvalidated rolling upgrade. 3. "## Severity and risk": present. It states "Severity: medium." and gives a "Risk:" list covering the migration-window and rollback risks. 4. "AI assistance:" line: present. The line begins "AI assistance: Perplexity Computer drafted the code, the restore migration and the first description..." Prior failure disposition: the previous FAIL cited a different description. That version had "## Why", "## Data safety", "## Mixed-version note", and "## Follow-up" headings, no "## Severity and risk", and only a footer AI reference. The description now under review has been rewritten. It contains the required headings and the "AI assistance:" line, so the prior missing items are resolved. The review-thread findings concern code behavior, not the description template, so they do not affect this presence-only check. Prior failure addressed: The current PR description contains a '## Summary' section, a '## Validation' section stating 'CI on this head', a '## Severity and risk' section with 'Severity: medium.' and a 'Risk:' list, and a line beginning 'AI assistance: Perplexity Computer drafted...'. The prior failure's missing Severity and risk section and AI assistance line are now present.

Full details: Bug Fixes Name A Regression Test

Explanation

The check applies only when the PR fixes a defect in application behavior under crates/, shim/, or ui/. PR #1780 is a partial revert of #1713 for rollout compatibility. Its stated purpose is to let releases that still read legacy_state and publish CLEANUP_REQUIRED/CLEANUP_FAILED roll out or roll back safely. The description does not report a defect in current behavior. It describes a rollout-ordering problem, and its severity note covers the upgrade path only. The changed-file inventory is a broad revert across crates/, shim/, proto, docs, and migrations. It is a restoration of retired lifecycle values and readers, not a targeted bug fix. Because the PR is not an application bug fix, the check does not apply and passes. The PR also does not name a fail-before/pass-after regression test. That gap would matter only if the PR were a bug fix.

Full details: Weakened Safeguards Are Justified

Explanation

The diff removes two tests. The PR description gives a specific reason for each, so the check passes. 1. crates/l40_api/node/ctl/server/src/facets/tests.rs (hunk @@ -1320,43 +1320,6 @@): a_cleanup_owned_row_publishes_its_cleanup_status is removed. It is absent at head. The PR description names it and states that it covers retired behavior from #1713 and returns when #1713 re-lands. 2. shim/space_test.go (hunk @@ -2493,28 +2495,11 @@): the FailedPrecondition loop for a cleanup over STARTED, STOPPED, or SUSPENDED is removed. The PR description names this case and gives the same reason. New comments in the same diff, such as "Outside CLEANUP_*", state the changed rule. Other test changes do not weaken coverage: - shim/lifecycle_test.go now expects values 15 and 16 to be accepted, and the earlier skips for them are removed. - crates/l30_storage/db/migrate/src/tests.rs adds a rollback step before the assertions. - Removals of ObservedStatus, ownedCleanup, and the status-count tests pair with removed types or with the revert. Replacement coverage is in the same diff. Other categories were checked and not found: no added #[allow], #[expect], #[ignore], skip, xfail, continue-on-error, SPACE_TEST_DEPS_OPTIONAL, nextest, or allowlist changes. The only guidance file changed is crates/l30_storage/sbx/mgr/store/AGENTS.md. It adds a note about keeping legacy_state and does not loosen any rule or touch review or approval guidance. Prior failure disposition: the prior FAIL stated that both removals had no stated reason. The PR description names both tests and gives the reason for each, so that claim is refuted. Prior failure refuted: The prior failure said the removed facets test a_cleanup_owned_row_publishes_its_cleanup_status had no stated reason.

Full details: Agent Tooling Runs No New Commands

Explanation

The check fails only when the diff adds or changes agent plugin manifests, skill files, command files, or guideline files so that agent tools run something. I checked the full changed-file list (PR #1780, head vs. merge base). It has no plugin.json, plugin.yaml, SKILL.md, skill, command, hook, MCP, or LSP files. The only guideline file touched is crates/l30_storage/sbx/mgr/store/AGENTS.md. Its +3/-1 change is prose about legacy_state. The other documentation changes (docs/configuration.md, docs/observability.md) are also prose. I searched every added line in the diff for inline shell substitution (! followed by a backtick), hooks, mcp, lsp, allowed-tools, plugin, SKILL, and command:. None matched. The remaining changes are Rust, Go, proto, SQL, and test code. No new command runs, process starts, or server connection is added in agent-facing content. The check passes.

Full details: Public-Safe Content

Explanation

The PR title, the supplied description, and the added diff lines contain no content that the Public-safe content check prohibits. - Diff scan: I scanned all added lines in the reviewed range for URLs, hostnames, internal domains, tracker names, ARNs, key or token patterns, personal absolute paths, IP addresses, and environment names. The only hits were 12-digit migration IDs such as 20261109120000 in comments and migration paths. These are repository migration identifiers, not cloud account IDs or ARNs. The word "prod" did not appear as an environment name in the added lines. - Description: The supplied description has no footer link to a private chat or task session. It names no Datadog monitors, dashboards, or external tracker. It names no prod or testing environment and gives no pod counts, commit pins, or prod-only settings. It refers to other PRs only by same-repository number (#1709 to #1713) and to a public upstream commit. Dashboard and monitor consumers are described generically ("dashboards and monitors outside this repository"). The description attributes drafting to AI tools by name, which is not sensitive. - Other items: No credentials, private keys, personal paths, production logs or measurements, incident details, or undisclosed vulnerability descriptions appear in the title, description, or diff. Prior failure disposition: The standing FAIL cited three items in the description: a footer link to a private task session, Datadog monitor and dashboard names with an internal tracker reference, and prod/testing environment and rollout details. The current supplied description contains none of these. This is the evidence I relied on. I could not re-read the live PR body with a tool, so this depends on the supplied description matching the current PR. Prior failure addressed: The current PR description has no footer link to a private task session, no Datadog monitor, dashboard, or ppl-ai tracker names, and no prod or testing environment, commit pins, prod-only setting, or pod-count details. Metric consumers are described generically. The added diff lines contain no sensitive patterns; the only 12-digit matches are migration IDs.

Failed pre-merge checks:
- Title check:
Rewrite the title to start with a lowercase area and a colon, or a bracketed
area, followed by a lowercase summary. Remove the PR number reference. For
example: "sbx-mgr: revert cleanup lifecycle retirement and restore
legacy_state". Keep the title free of a trailing period and ticket IDs.

- Description Follows The Pr Template:
Edit the PR description to add the following: - A "## Severity and risk"
section. Give a severity (or "does not apply") and state the risk. The existing
mixed-version and data-safety notes can supply the risk text. - A line that
starts with "AI assistance:". Use "AI assistance: None" or name the tool and the
parts it drafted or changed. The footer does not satisfy this item.

- Weakened Safeguards Are Justified:
1. In `crates/l40_api/node/ctl/server/src/facets/tests.rs`, restore
`a_cleanup_owned_row_publishes_its_cleanup_status` (base lines 1323–1359), or
add an equivalent test that asserts `cleanup_required` and `cleanup_failed`
publication for `Stopping`, `Deleting`, and `Suspending` rows with
`state_degraded == false`. If the removal is intended, state the reason in the
PR description and in a code comment. 2. In `shim/space_test.go` (hunk `@@
-2493,28 +2495,11 @@`), either restore the `FailedPrecondition` check for a
cleanup over `STARTED`, `STOPPED`, or `SUSPENDED`, or add a comment and a
PR-description note that explains why this coverage is removed.

- Public-Safe Content:
Edit the PR description and remove the following: - The footer link to the
private Perplexity task session. - The Datadog monitor and dashboard names and
the `ppl-ai/space` tracker reference. Describe the metric consumers generically,
for example "external dashboards and monitors query this metric." - The prod
commit and pin identifiers, the `prod` and `testing` environment names, the
prod-only configuration setting, and the pod-count and rollout details. Replace
them with generic statements, for example "the currently deployed release reads
`legacy_state`." Then push the edited description. No code change is needed.
