[control-plane] drop cleanup_required from the stored lifecycle vocabulary - #1553
Merging this removes cleanup_required from the control plane's stored lifecycle vocabulary. It is a node-local sandbox-manager cleanup status, and no control-plane writer stores it in Postgres sandboxes.lifecycle: finalize_delete, which the placement crate's README (since deleted) said would produce it, was never implemented.
StoredSandboxLifecycle::CleanupRequired goes, leaving deleted as the only tombstone (crates/l30_storage/sandbox/store/src/lifecycle.rs).
The value leaves the SQL exclusion lists, the residency and orphan-sweep constants, the public API and ECW tombstone filters, the admin list filter, the E2B connect mapping, the auto-lifecycle delete-completion reason and the UI's stored-lifecycle filter.
Node-reported CLEANUP_REQUIRED/CLEANUP_FAILED are unchanged, and the UI status filter still offers them.
The admin sandbox list keeps accepting lifecycle=cleanup_required for one release, as a filter that matches no row, so an older console or a saved link gets an empty page rather than a 400. It goes with the cleanup-state retirement.
This is the control-plane part of moving CleanupRequired and CleanupFailed out of the sandbox lifecycle; the rest of the stack does the node side.
Validation
Tests: reads_answer_a_deleted_tombstone_as_not_found (the route-level 404 and list exclusion, kept for deleted), the_lifecycle_filter_takes_exactly_the_stored_lifecycles (with the retired filter value), each_surface_renders_stored_lifecycle_and_observed_status (24 regenerated shards), a_matrix_missing_a_stored_lifecycle_is_refused and the stored_lifecycle_matrix tables.
Tests drop the cleanup_required rows from the stored-lifecycle matrices and keep it where it stands in for a stray value (orphaned restore-pod classification, the termination gate's unmodelled values).
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; this removes a value no writer produces.
Risk: a deployment that does hold a cleanup_required row would now treat it as unknown text, counted as resident and woken rather than excluded as a tombstone. Roll back by reverting this PR.
Rollout
Do not merge until, on every deployment, SELECT count(*) FROM sandboxes WHERE lifecycle ~* '^\s*cleanup_required\s*$' returns 0. (The regex covers the tabs and newlines Rust's trim used to accept, which Postgres trim doesn't.)
Stack
Part of a stack that moves CleanupRequired and CleanupFailed out of the sandbox lifecycle into their own cleanup state. Merge in order; #1552 has merged, so this PR is next.
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.
Why: Lifecycle guards and public reads change. Existing cleanup_required rows would cause read errors, so verify the zero-row rollout precondition before merging.
Commit: 6accc8f0f17e.
No actionable comments were generated in the recent review.
Walkthrough
The changes remove cleanup_required from the stored lifecycle model and make deleted the sole stored tombstone. Storage writers, public and admin queries, lifecycle reporting, and controller policies now handle cleanup_required separately from stored lifecycle values. Admin lifecycle parsing retains compatibility with the retired value. Public reads and lists exclude only deleted.
perplexityai/SPACE#1416: Changes public-read, ECW, and connect handling for cleanup_required, which this PR revises.
perplexityai/SPACE#1420: Changes activation rollback handling for rows with unparseable stored lifecycles, which is connected to this PR admitting cleanup_required rows to activation rollback candidate selection.
Merge Risk: High · up to 6accc
Lifecycle guards and public reads change. Existing cleanup_required rows would cause read errors, so verify the zero-row rollout precondition before merging.
Security architecture risk: Low · up to 6accc
Organization boundaries remain enforced, and node-reported cleanup statuses do not create the retired stored value. The remaining risk is conditional: existing rows containing that value would behave differently during reads and lifecycle processing. Deployment data confirming their absence was not supplied.
Retained concerns
Low · architecture · inferred: Removing terminal-value fences depends on an unverified persisted-state precondition. If cleanup_required rows survive in a deployment or restored database, public reads can fail instead of hiding them, and matching activation receipts can project live target states onto rows previously excluded as terminal. This is a conditional compatibility and lifecycle-ownership concern, not evidence that such rows exist or that an attacker can create them.
Security review details
Security Blast Radius
inferred — The demonstrated conditional read failure is bounded to an affected sandbox and list pages containing it within the existing organization and ownership scope. The evidence does not establish cross-organization exposure, privilege gain or an ordinary API path for creating the retired stored value.
Security Findings and Attack Paths
inferred — If an otherwise eligible exact cleanup_required row exists, the changed SQL admits it where the base excluded it. Native projection then rejects its lifecycle, changing GET from not-found to an internal error and potentially failing an included list page. Production presence and an attacker-controlled source for such a row were not established, so this is not a verified exploit path.
Trust Boundaries and Controls
observed — The lifecycle-filter changes preserve organization and owner predicates. Retired rows would also count toward organization and subject quotas rather than bypass them; the relevant quota exclusions now contain failed, quarantined and deleted.
Resilience and Maintainability Implications
observed — Activation completion retains a single-statement execution release and lifecycle projection. It requires the publisher's assigned node, an active execution, matching generation and activation attempt, matching receipt target and a valid execution condition. Suspend, quarantine and delete fences remain, but cleanup_required is no longer excluded. Matching execution state is therefore an important limit on the conditional terminal-state concern.
Hardening Proposals
proposed — Before deployment, verify that supported databases and restore sources contain no cleanup_required lifecycle values, including normalized case and whitespace variants. If any exist, reconcile their cleanup and ownership state or retain compatibility handling before removing their terminal protections.

crates/l40_api/api/src/controllers/sandbox/list_page/admin.rs:35: the admin list now answers lifecycle=cleanup_required with a 400. The plan's D3 says to keep accepting it, returning nothing, for one release.
Mechanism: with TOMBSTONE_LIFECYCLES = [DELETED_LIFECYCLE], AdminStoredLifecycle::from_str("cleanup_required") now fails, and parse_lifecycles in routes/admin/sandbox_list.rs turns that into 400 unknown lifecycle. The console offered and sent this value as a stored-lifecycle filter before this PR (ui/src/lib/sandbox-lifecycle.ts:30 at the base). So while the API and UI deploy at different times, an old console tab, a saved filter link or a script gets a 400 where it used to get an empty page.
The gap: the PR body says the rejection is deliberate, but not why D3 was dropped.
Choices:
Follow D3: accept the value in AdminStoredLifecycle::from_str as a filter that matches no rows, with a test, and refuse it a release later. That costs a short-lived special case.
Keep the refusal: that costs one release of 400s for old clients. If that's the choice, update the plan and give the reason in the body.
Low
The read-only precondition (SELECT count(*) … WHERE lower(trim(lifecycle)) = 'cleanup_required') can miss rows that the removed Rust code treated as cleanup_required. Postgres trim strips only spaces. Rust's str::trim(), used by StoredSandboxLifecycle::from_str and is_tombstone, also strips tabs and newlines. In a postgres:16 instance, ' Cleanup_Required ' matched but E'cleanup_required\n' and E'\tcleanup_required' didn't. lifecycle ~* '^\s*cleanup_required\s*$' covers what the old parse covered. This is very unlikely to matter, since nothing ever wrote the value.
crates/l40_api/api/src/routes/public/sandboxes/tests.rs: deleting reads_answer_a_cleanup_required_tombstone_as_deleted also removed the only route-level test of deleted, which still exists. That test also sent GET /v1/sandboxes/{id} and GET /v1/sandboxes for a deleted row, asserting 404 and exclusion from the list. The surviving sandbox_reads_exclude_deleted_tombstones_before_pagination checks only the store read (fetch_public_sandbox returns None). Keeping the test with just the deleted row would retain that coverage.
Verified against 6be8f33dd6f93f73bc13b1bb8286c41aaf919d40.
What I ran:
nextest on placement, the sandbox store and common-svc: 237 of 237 pass.
nextest on pplx-space-api, filtered to every touched module: 412 of 412 pass.
The UI's sandbox-lifecycle.test.mjs: 9 of 9.
Probe tests at this head for a stray cleanup_required row:
ECW renders it as running;
E2B connect no longer refuses it;
the wake compare-and-set lets it move to started;
auto-lifecycle delete completion acknowledges it as unknown_lifecycle;
quota and residency count it as live;
orphan GC still doesn't select it, because its candidate scan uses include-lists.
That matches the body's description of an unexpected value. With no writer, the count before deploy is the protection.
What I read:
No control-plane writer outside sbx-mgr can produce the value. Each binds a typed lifecycle or a literal.
Removing one element from each exclusion list changes the answer only for that element.
Not run: the cluster-controller, internal-api and metrics tests. Their changes are table rows, one constant and comments.
Thanks @the-gigi-pplx. Rebased the stack on main (47f3aa39); this PR's head is now d3f2b9c631a7.
Admin lifecycle=cleanup_required. You're right that I dropped the plan's D3 without saying so. AdminStoredLifecycle now also takes a short RETIRED_LIFECYCLES list (cleanup_required) for one release. Nothing stores the value, so the filter matches no row, and old consoles and saved links get an empty page instead of a 400. the_lifecycle_filter_takes_exactly_the_stored_lifecycles pins it, and the admin API docs say so. It goes with the retirement.
Precondition query. Switched it to lifecycle ~* '^\s*cleanup_required\s*$' in the Rollout section and the commit message.
Route-level deleted coverage. Restored as reads_answer_a_deleted_tombstone_as_not_found: GET /v1/sandboxes/{id} is 404 and GET /v1/sandboxes leaves the row out.
The rebase also brought in main's published_status (#1411), which parsed a node's cleanup_required as a stored tombstone. It now reads as Unrecognized, like cleanup_failed. No ingest decision compares either, and its test says so.

…ulary
`cleanup_required` is a node-local sandbox-manager cleanup status. No
control-plane writer stores it in Postgres `sandboxes.lifecycle`:
`finalize_delete`, which the placement crate's README (since deleted) said
would produce it, was never implemented. Yet every lifecycle guard and residency list carried it, and
three comments disagreed about whether it was a planned tombstone, a value
that "reaches this column from nowhere", or one kept for older schemas.
Remove `StoredSandboxLifecycle::CleanupRequired`, leaving `deleted` as the
only tombstone, and drop the value from the SQL exclusion lists, the
residency and orphan-sweep constants, the admin list filter, the E2B
connect mapping, the auto-lifecycle delete-completion reason and the UI's
stored-lifecycle filter. Node-reported `CLEANUP_REQUIRED`/`CLEANUP_FAILED`
are unchanged; the UI status filter still offers them.
The admin sandbox list keeps accepting `lifecycle=cleanup_required` for one
release, as a filter that matches no row, so an older console or a saved
link gets an empty page rather than a 400.
Precondition before merge: on every deployment,
`SELECT count(*) FROM sandboxes WHERE lifecycle ~* '^\s*cleanup_required\s*$'`
returns 0. A stray row would now be treated like any unknown text: counted
as resident and woken rather than excluded.
Tests drop the `cleanup_required` rows from the stored-lifecycle matrices
and keep it where it stands in for a stray value (orphaned restore-pod
classification, the termination gate's unmodelled values).
Restored the request_id assertion in reads_answer_a_deleted_tombstone_as_not_found and rebased the ten-PR stack onto current main. The deleted-sandbox response retains its original assertion coverage.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.
The admin sandbox list kept its own copy of the stored lifecycle
vocabulary, `AdminStoredLifecycle`, for `?lifecycle=` filters. It trimmed
and lowercased the input, accepted the tombstone `deleted` and otherwise
parsed `SandboxLifecycle`, which is what `StoredSandboxLifecycle` does,
and also took the retired `cleanup_required`, which no row stores. The
copy existed because that type lived in a crate the api used only in its
tests, and a test pinned the two parses together.
`StoredSandboxLifecycle` now lives in `pplx-space-sandbox-store`, which
the api already depends on, so the filter and `parse_lifecycles` use it
directly and the copy goes, with its tombstone list and the test that
pinned the two parses. The retired list moves to `parse_lifecycles`, and
that test's check that `cleanup_required` is still taken moves with it.
The SQL still binds `as_str()` of each value.
Behaviour-free for every stored value: the accepted inputs, their
normalization, the binds, and the error for an unknown value are
unchanged. `cleanup_required` is still accepted, normalized the same way,
for the release #1553 promised, but `StoredSandboxLifecycle` has no such
value, so `parse_lifecycles` drops it instead of binding it: a filter
naming only it binds an empty list and matches no row. That error is
still built at the route, so its status and message stay as they were.
The route's tests checked only that the message contains `unknown
lifecycle`, not the item it names. A new test pins the whole body and
checks that mixed-case, space-padded stored values are accepted, now that
no copy is there to compare with. It also seeds rows in matching and
non-matching lifecycles, a `deleted` tombstone and a stray
`cleanup_required` row among them, and checks that the unpaged and the
cursor lists return exactly the matching ones, and that a filter naming
only `Cleanup_Required` returns none.

Summary
Merging this removes
cleanup_requiredfrom the control plane's stored lifecycle vocabulary. It is a node-local sandbox-manager cleanup status, and no control-plane writer stores it in Postgressandboxes.lifecycle:finalize_delete, which the placement crate's README (since deleted) said would produce it, was never implemented.StoredSandboxLifecycle::CleanupRequiredgoes, leavingdeletedas the only tombstone (crates/l30_storage/sandbox/store/src/lifecycle.rs).CLEANUP_REQUIRED/CLEANUP_FAILEDare unchanged, and the UI status filter still offers them.lifecycle=cleanup_requiredfor one release, as a filter that matches no row, so an older console or a saved link gets an empty page rather than a 400. It goes with the cleanup-state retirement.This is the control-plane part of moving

Severity: does not apply; this removes a value no writer produces.
Risk: a deployment that does hold a
