[cr-test] api: render what callers see from the stored row for terminal sandboxes - #1639
When the control plane marks a sandbox failed (for example the lost-started reconciler) while its node's observed record still says started, ECW GET /sandboxes/{id} answered "state":"running" and connect went ahead. ECW read the observed status before the stored lifecycle and reads any status it doesn't name as running. ECW list reads the stored lifecycle, so the two disagreed: a failed row was hidden from GET /v2/sandboxes but running in GET. The tombstones deleted and cleanup_required read as running on every ECW surface, list included. Separately, native GET /v1/sandboxes/{id} answered 500 for a cleanup_required row.
ECW reads the stored row (SandboxStateInput::rendered_lifecycle, routes/e2b/translate.rs).
The stored lifecycle decides every terminal and at-rest row: failed, quarantined, stopped, suspended, deleting, deleted, cleanup_required.
The observed status refines a live row only when it was published by the row's active node (Sandbox.active_node_id, already the direct route's node when there is one). The observed record has no execution generation to compare.
ECW reads both tombstones as deleted: hidden from list, 404 from GET and from the gate that connect, timeout and refresh share.
Admin lifecycle/status and native state are unchanged.
Native GET answers cleanup_required exactly as deleted. The by-id read excludes both, so the answer is deleted's on main: 404 {"code":"not_found","message":"sandbox not found","retryable":false,"details":[]}.
Changed test expectations
Render table, commit 1: 203 existing rows change, all with stored failed, quarantined, stopped, suspended, deleting, deleted, cleanup_required or padded Stopped/Suspended.
Their ECW get, gate, wake, pod and touch-recovery cells now equal the no-observation row.
ECW list changes only for the tombstones (running → hidden).
No admin or native cell, and no live-lifecycle row, changes.
Render table, commit 1: 63 new rows, observations started/paused/failed from a node other than the active one.
Render table, commit 2: the native cell of all 31 cleanup_required rows goes from 500 to 404.
connect_route_never_bad_gateways_for_db_state_shapes: the cleanup_required row expects 404, as deleted does, not 409.
New: get_answers_a_cleanup_required_tombstone_as_deleted compares the two tombstones' status and body through the /v1 router.
Validation
Both table tests and the connect test fail on main's code (stored failed + observed started: get=running gate=pass). The native test fails on commit 1 (500 vs 404).
SPACE_CI_REQUIRE_TEST_DEPS=1 cargo nextest run --all-features -p pplx-space-api -p pplx-space-api-svc -p pplx-space-cluster-controller-server: 3475 passed, Postgres running. The only skip is an ignored benchmark.
Kind, fresh cluster from this head (SPACE_KIND_TELEMETRY_MODE=otel up.sh, 9.4 min). Created an ECW sandbox, then set its row to failed with SQL while its node still reported started:
ECW GET failed, list hid it, connect 500.
Set to cleanup_required: ECW GET and connect 404, native GET 404.
On main's API, rebuilt on the same cluster: ECW GET running for both, list running for cleanup_required, native GET 500.
SKIP_BOOTSTRAP=1 scripts/tests/smoke-kind-typed.sh all (admin token, SPACE_SMOKE_KIND_COLD_RECEIPTS): ECW 91 passed, native 42 passed, 0 failed or inconclusive, 66 min, no reruns. Console scenarios skipped without Playwright, as CI withholds them.
Severity and risk
Severity: medium. ECW clients polled and connected to a dead sandbox as running, and native GET returned 500.
Risk:
A live row no longer follows an observation from a node it has left.
Native :set_timeout reads the same gate after its own state check: a suspended row whose node still reports failed/stopped is no longer refused, and a cleanup_required row answers 404, not 500.
deleting keeps its stored ECW reading, running.
Rollback: revert either commit. There are no migrations.
Mixed versions: old and new replicas read the same rows. During a rollout, ECW GET for an affected row can differ by replica. No stored state changes.
Stack
Commit 1 is ac/lifecycle-ecw-render-from-row and can merge alone. Commit 2 builds on its render table.
Not covered
Native GET /v1/sandboxes (list) still answers 500 for any page holding a cleanup_required row (seen on Kind). It is left unchanged here.
AI assistance: Claude Code drafted the code, tests and this description.
Why: The native sandbox GET response changes for cleanup-required sandboxes. Confirm that this versioned API behavior is acceptable before merging.
Commit: 9f1436778304.
Walkthrough
Sandbox state rendering now distinguishes observations from the active node from observations reported by another node. ECW lifecycle mapping hides tombstone states and maps them to stopped terminal outcomes. Public by-ID reads now exclude both deleted and cleanup_required sandboxes. Tests cover other-node observations, ECW state mappings, connect-route behavior, and matching public responses for the two tombstone states.
Possibly related issues
SPACE issue 835 — The PR hides deleted and cleanup_required rows from ECW rendering, as described in the issue. It does not address the issue’s pagination behavior.
Possibly related PRs

Merge Risk: High · up to 9f143
The native sandbox GET response changes for cleanup-required sandboxes. Confirm that this versioned API behavior is acceptable before merging.
Security architecture risk: Low · up to 9f143
The change prevents stale observations from overriding stored terminal states and hides deleted sandboxes more consistently. Existing tenant ownership checks remain in place. The remaining uncertainty concerns observation freshness across repeated executions on the same node, rather than an identified new authorization bypass.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The inspected change affects visibility and permitted lifecycle actions for an already-authorized sandbox. It does not expand the tenant scope selected by ECW ownership checks or the native by-ID organization predicate.
Trust Boundaries and Controls
observed — ECW resolves authenticated local or federated ownership before scoped sandbox reads. Local access requires the local organization; federated access requires the matching upstream identity or the API key's legacy local organization. State translation remains downstream of this boundary.
Resilience and Maintainability Implications
inferred — Matching node IDs establish observation origin, not freshness across executions on that node. The rendering contract explicitly lacks an execution-generation comparison, so same-node retry or recovery freshness remains unproven. This limitation predates the PR's narrower rejection of different-node observations and is not an established introduced vulnerability.
