Summary

A suspended sandbox restores from one rule on every path. The rule never loads an older capture in place of a newer one when it can tell them apart, and refuses when it can't. The Kubernetes suspend selector, the Direct substrate's restore on another node, and GetSuspendSnapshotLocation (the fallback a node uses when it has no URI and no local copy) share it.

A pinned sandbox restores exactly its pinned artifact.
An unpinned one restores only from suspend captures. They're ordered by the generation of the execution that captured them (snapshots.generation), then by when each capture first registered, so a re-upload of an older capture never outranks the latest one.
Where nothing can order two captures, the restore refuses with an explicit reason instead of guessing. The refusal applies only where a restore source is chosen or a source copy is released. It never fails, unpins or strands a row, and an operator can resolve it by pinning a capture through a new admin route.

Node-local idle suspends now pin their capture: by its generation, or, for a capture without one, by the node's report that it holds it. A repair loop, off by default, backfills pins for suspended sandboxes from the artifact their node still holds.

Terms

Pin: sandboxes.current_local_artifact_id, _kind and _origin, the exact artifact a suspend published. A pinned restore loads only that artifact.
Registration time: snapshots.timestamp, set when BeginArtifactBackup inserts the attempt row. A later backup attempt of the same bytes gets a new row and a new timestamp.
Capture generation: snapshots.generation, the generation of the execution that captured the bytes, recorded when the node vouches for it. Every backup row of one artifact inherits the first recorded generation.
Re-upload: a fresh backup attempt of an artifact captured earlier, such as the node-drain reupload queue or a disk eviction's upload before delete.
Unordered history: an unpinned sandbox with a capture without a generation, registered after one with a generation, that no later execution's capture provably follows. Either could hold the latest state.

The problem

Every restore path picked "the newest backup" somewhere by registration time, and registration time isn't capture time. A re-upload of an older capture is the newest row, so it wins, and the restore silently rolls the sandbox back to that capture.

Three copies of the selection disagreed. The Direct remote candidate (direct_restore_candidates_for_mode) took the newest ready full row by timestamp, with no pin check and no origin filter. So a backup of a user's named snapshot or a re-upload of an older capture could be restored instead of the latest suspend. The node fallback returned the newest ready suspend row by timestamp. The Kubernetes selector honored the pin, but these all ranked by registration time:
- its retry window;
- its node-drain mode for unpinned rows;
- the no_newer_full_snapshot gate the drain and repair paths share.
None of them except the node fallback filtered by origin. A named snapshot is taken while the sandbox runs, so one that registers after the suspend capture of the same execution is older state, and it won by registration.
Few sandboxes were pinned. Only an API suspend pins its row. A node-local idle suspend is finalized by internal-api's projection (project_ready_suspend_snapshot, and the node census). That projection passed no artifact, and cleared a pin left from an earlier cycle. So an idle-suspended sandbox always restored by order, and order was registration time.
Ordering by generation alone leaves a gap. A capture the node can't vouch for registers without a generation. Take a re-upload of an older capture, registered without one after the latest capture with a generation: generation can't order the two, and falling back to registration time picks the re-upload. Captures from before generations were recorded are the same kind of row, and at rollout every sandbox has them.

How this fixes it

One selector in the store layer. pplx_space_sandbox_store::restore_source::select_restore_source holds the rule, and returns Selected, Unavailable or Unordered.
- A caller names one of four modes (RestoreSourceMode) and where the sandbox may be placed:
  - PlacementFresh for a user restore on the sandbox's own node;
  - NewestFull away from it;
  - Retry;
  - NodeLookup for GetSuspendSnapshotLocation.
- Each mode and placement is one statement, built once.
- A retry takes its pre-claim source window, or, when the pin has a backup registered before the claim, only the pinned artifact: that's the state the restore started from. Otherwise a pinned row takes only its pinned artifact, and an unpinned row takes only suspend captures (origin suspend or unrecorded), under its mode's rule.
- The Kubernetes selector, the Direct remote leg and GetSuspendSnapshotLocation call it. Direct gains the pin check, and its source-node leg reads its compatibility metadata from the same capture. latest_ready_suspend_location_placed_on is deleted.
Captures order by rank, then by first registration.
- Rank. capture_rank is a row's generation, or its artifact's, when another backup of the same artifact records one.
- Rank 0. A row without a generation ranks 0, below every generation, when a later execution's capture provably follows it: the sandbox's execution of that capture's generation started (sandbox_k8s_executions.created_at) after this capture first registered. Neither a pruned first backup nor a capture first uploaded long after it was taken can fake that. Direct keeps no execution history, so there a later-registered capture with a higher generation than every capture registered before this one still ranks it below.
- Within a rank. Among rows of one rank, capture_registered_at decides: the earliest registration of any backup of the row's artifact. So every re-upload of an artifact sorts with its first backup.
- Shared. no_newer_full_snapshot and the retry and outranking fragments use both, so the drain gates, the drained-node terminator, the repair paths and the admin runtime-environment population agree with the selector.
- Same-execution captures. A later capture of the same execution that's still uploading doesn't hold an earlier one, as before: only a later execution's capture outranks.
An unordered history refuses explicitly, where a source is chosen. restore_order_unordered holds for an unordered history, and an unpinned row's selection returns Unordered. A history where no capture has a generation keeps registration order, now by first registration, so legacy sandboxes still restore. A retry judges its history by its pre-claim window alone. Per path:
- On the sandbox's own node. The restore loads that node's local copy, the state the sandbox last suspended with there.
  - Kubernetes falls back to a node-only pod while that node is registered and ready, answering a retryable 503 while it's registered but not ready.
  - Direct keeps its source-node leg, answering a retryable 503 while the node is registered but not a candidate.
- A node without the copy. GetSuspendSnapshotLocation answers FAILED_PRECONDITION. Sandbox-manager maps that to a terminal RestoreError::RestoreSourceUnordered, and tags its own refusal with x-space-restore-refusal: source-unordered, which the Direct substrate maps to the terminal 412 instead of trying another candidate.
- An evacuation, or no source node. Both substrates answer 412 (RestoreContextUnavailable), which reconnect classifies as a terminal wake_failed.
- The other selectors that choose. The markerless quarantine recovery refuses it too.
Only choosing and releasing refuse. These keep the refusal for an unpinned unordered sandbox:
- the release gates (snapshot_durable_for_source_release and the gates built on it): its source node isn't released while its restore would refuse. An unpinned row's source is released only on a suspend capture that's newest among suspend captures, since a later capture's bytes may be only on that node. For an unmarked row only a later upload that hasn't failed holds it, which ends: the node's worker finalizes it or the stuck-snapshot reaper fails it. Nothing retries a failed one there, so a hold on it would park the drain for good. An evacuation-marked row is held by a failed one too, since the evacuating drain re-uploads it and fails the row once its bytes are gone;
- the markerless revert proofs that unplace a row;
- node drain's adopt give-ups.
These don't:
- Finalizing a node-local suspend uses started_suspend_finalize_eligibility, since it records the node's suspend and chooses nothing. The row reaches suspended instead of staying started.
- The drain's ArtifactMissing give-up and the drained-node terminator fail a row only without a durable copy (snapshot_durable_copy_exists). An unordered history keeps every ready durable copy, evacuation-marked or not, even one later failed uploads outrank, and any row keeps a copy the release gate would accept. It stays suspended, still holding the source until it's pinned.
- A failed restore's pod cleanup doesn't revert, and so doesn't unpin, a pinned row whose history is unordered. The sweeper's revert, which keeps the pin, handles it.
Eviction keeps a copy the cluster can't restore without. Before evicting a suspended copy, sandbox-manager asks DurablyRestorable, and skips the sandbox (no_backed_copy) when the cluster can't restore it without the copy. is_latest_ready_suspend, the unpinned eviction proof, is never true for an unpinned unordered history, so a node that predates this change doesn't evict such a copy through it either.
Retention keeps what the order rests on, and no more. snapshot_is_live_restore_source shields an unpinned sandbox's possible picks: every backup of the latest capture, and, while the history is unordered, the latest capture on each side. An outranked capture prunes by rank. Because the order is derived from the rows that exist, retention also keeps the rows it rests on:
- an artifact's first backup while later backups of it remain and nothing outranks it, or while it ranks 0;
- an artifact's first backup with a generation while a backup of it without one takes its rank from it;
- while the history is unordered, every row registered at or before a capture that makes it so, pinned or not, since a pin can be cleared later.
Placement freshness, in the selector and the release gates, compares the capture's first registration too.
Idle suspends pin their capture. suspend_snapshot_is_current_capture proves a ready full suspend backup is the capture of the execution being suspended:
- it records the active execution's generation;
- its capture first registered since the row's last lifecycle change;
- no full snapshot is newer by capture.
For a capture without a generation, the node's suspended report is the proof: node_held_capture_is_latest, shared with the repair, pins the artifact the node reports holding when all of these hold:
- its backup from that node registered since the suspend began;
- nothing outranks it;
- no other suspend capture registered at or after it.
A capture with another execution's generation isn't pinned.
A repair loop backfills pins. restore_pin_repair, in the cluster controller, runs for both substrates and is off unless SPACE_RESTORE_PIN_REPAIR_ENABLED is on. It pages through the running substrate's unpinned suspended rows that have a ready suspend backup.
- Asking the node. For each row, it asks the node the row is placed on which artifact it holds suspended (node-api SandboxState, reached through a new SubstrateAdapter::node_api_target), several nodes at a time.
- The write. repair_restore_pin pins it in one guarded statement, while the row is still in the same suspend and placed on that node, and the node's backup passes node_held_capture_is_latest.
- Refusals. A row it can't pin is logged with the reason.
- Shutdown. A tick stops at shutdown before its next node call or pin write.
An operator can pin a capture. GET /admin/api/v1/sandboxes/{id}/restore-pin lists a sandbox's restore state and the captures a pin accepts: in an unordered history, the latest capture of each side. POST first asks the sandbox's node what it holds, since a node holding the sandbox suspended restores its own local copy whatever the pin names. It refuses (409) while the node holds another capture or a copy with no recorded capture, and answers 503 while the node can't be asked. Then it pins through restore_pin::pin_restore_source, which accepts only a suspended, unpinned row unchanged since the read and a listed capture, and answers 409 otherwise. A capture outranked only by a failed upload is listed: that upload won't land. The admin CLI README has the runbook.
JIT is off for service sessions. pplx_space_postgres_pool's service pools set jit=off on their connections, and ci/scripts/lib/test-deps.sh starts the test Postgres with it. These are short, index-driven statements, and compiling them costs far more than running them.
The probes stay per sandbox. The fragments:
- check whether a sandbox has any capture with a generation before ranking its rows without one;
- evaluate the unordered check once per sandbox;
- skip the rank for a row that can't outrank anything.
So fleet-wide reads such as node occupancy and the drain gates read only the sandboxes' own histories.
One recording rule for snapshots.generation. The first backup of an artifact to record a generation fixes it, and every later backup of that artifact inherits it in snapshot_store::insert. An advisory lock per artifact serializes concurrent registrations.

Comparisons of a snapshot against a sandbox clock (placement_changed_at, lifecycle_changed_at, the activity clocks) stay on the row's registration time. The node-side stale-copy check stays as the backstop.

Validation

Selector, in crates/l30_storage/sandbox/store/src/restore_source/tests.rs (Postgres). All of these tests are new in this PR.
- a_new_backup_of_an_older_capture_never_outranks_a_newer_capture: capture A, a newer capture B, then a new backup of A's artifact, with generations and without, through every mode. All restore B.
- a_capture_without_a_generation_after_one_with_is_refused_unless_ordered: unordered histories are Unordered on every mode, and the gates agree. A later execution's capture, or captures from before generations were recorded, order them. A pinned row restores its pin.
- a_capture_ranks_below_a_later_execution_only_when_that_execution_started_after_it: a later capture whose first backup was pruned, and one first uploaded after the capture without a generation, both refuse. They're ordered only when the execution started after that capture registered, or on a sandbox with no execution history.
- an_unpinned_restore_never_takes_a_named_snapshot: a named snapshot of the same execution registered after the suspend capture is never restored. One of a later execution holds the restore.
- a_retry_never_restores_a_named_snapshot, pinned and unpinned, plus the retry-window and pinned-retry tests.
- the_population_binds_the_capture_the_selector_restores: the admin population binds the selector's pick for every history above, or counts it unrecorded when the selector refuses.
Finalization: node_local_suspend_pins_only_its_executions_capture (internal API), through the ready backup and through the node's report.
- A capture of the active execution is pinned.
- A capture without a generation finalizes and is pinned on the node's report only, including after an earlier capture with a generation.
- A retired execution's capture isn't pinned.
Give-ups: mark_lost_fails_only_suspended_rows_without_a_durable_copy (node drain) and drained_node_mark_lost_keeps_an_unordered_history_with_durable_copies (terminator). Neither fails an unordered history that has durable copies.
Cleanup: forget_pod_tracking_keeps_the_pin_of_an_unordered_restoring_row (Kubernetes store): a failed restore's cleanup leaves a pinned unordered row restoring and pinned.
Quarantine: pre_quarantine_recovery_refuses_an_unordered_history (internal API).
Eviction:
- eviction_keeps_a_backed_up_copy_the_cluster_cannot_restore_without (sandbox-manager) skips a marker-proven copy when the cluster can't restore without it.
- the_unpinned_eviction_proof_refuses_an_unordered_history (snapshot store) checks the unpinned proof, unordered, ordered and pinned.
Operator pin: an_operator_pins_either_side_of_an_unordered_history_and_nothing_older (sandbox store). Either side of an unordered history pins. An outranked capture, a named snapshot's backup, a stale lifecycle_changed_at, a pinned row and a started row are refused. a_pin_is_refused_while_the_node_holds_another_copy (admin route) covers the node check.
Refusals reaching callers:
- an_unordered_history_restores_only_on_its_source_node (Kubernetes) and an_unordered_history_restores_only_from_its_source_node (Direct) cover the own-node restore, the retryable 503 while the source node is registered but not ready or not a candidate, and the 412 with no source node or for an evacuation.
- restore_retries_node_local_candidate_errors (Direct): a node's tagged refusal is terminal, not another candidate.
- get_location_refuses_an_unordered_history_unless_pinned (internal API) and an_ambiguous_restore_source_is_permanent_not_a_retry_response (sandbox-manager) cover the node lookup.
Retention: p14_markerless_latest_capture_is_shielded_from_later_re_uploads covers:
- the possible picks;
- the first-backup anchors, including a rank-0 capture's;
- an unordered history whose rows up to the capture without a generation stay, pinned or not;
- an ordered history where nothing is held for its order.
Repair: the_repair_pins_only_the_nodes_latest_capture covers each guard, including a later named snapshot that doesn't refuse. The loop's tests cover pinning, unrepairable reasons, paging, concurrency, cancellation, the node-report mapping, and the switch's vocabulary and batch ceiling.
JIT: service_pools_turn_jit_off connects with the service pools' session options and reads SHOW jit as off.
Mutation checks: each new guard was mutated, 24 in all, and a test above fails for each.
Full run, locally on a Linux devbox at this head: the full workspace run through ci/scripts/run-rust-checks.sh.
- Unprivileged: all 12961 pass.
- Privileged: 72 of 78 pass. The six failures are node-runtime and guest-worker tests this change doesn't touch, which need what the devbox lacks (fs-verity, root-owned ancestors for the runtime directories, a private cgroup namespace).
- Clippy passes.

Not validated: a Kind or deployed restore, and the repair loop and the admin pin against a live node.

Rollout

There's no migration. Deploy, then enable SPACE_RESTORE_PIN_REPAIR_ENABLED on the cluster controller to backfill pins, and turn it off once the unpinned population stops shrinking.

While nodes roll out, an upgraded node records its captures' generations and an older one doesn't. A sandbox that suspends on an upgraded node and then on an older one gets a capture without a generation after one with a generation. What happens to that older node's suspend:

Finalizing. The control plane finalizes it, through the backup-ready projection or the node's census, so the row reaches suspended.
Pinning. The census pins its capture when the node's report names it as the artifact it holds suspended.
The remainder. A row that isn't pinned restores on its own node from the local copy. Off it, the restore refuses until the repair loop or an operator pins a capture, or a later execution's capture registers. The refusal is logged by sandbox-manager (restore_source_unordered) and answered as listed above.
Eviction. An older node still evicts a node-pinned copy on its backup marker alone, without asking whether the cluster can restore the sandbox without it. For such a sandbox, the admin pin is then the only way to restore.

Not covered

An unpinned re-upload mints a new artifact id, so a re-upload of an unpinned capture from before this change can't be tied to its first backup. In a history where no capture has a generation it still sorts by its own registration. The pins this change writes, and the repair, are what close that for existing sandboxes.
On Direct, which keeps no execution history, rank 0 still rests on registrations: a later-registered capture with a higher generation than every earlier one. A pruned first backup from before this change, or a capture first uploaded long after it was taken, can still order such a history wrongly there.
The admin population's count for a failed sandbox the repair loop could revert attributes it to the capture it would restore by order, without the unordered refusal: an unordered one is counted as recorded.
The repair asks only the node a sandbox is placed on. A sandbox whose node is gone, or no longer holds it suspended, stays unpinned for the admin pin.
A stored order key (snapshots.captured_at, set at insert) would let readers compare a column instead of deriving the order. It needs its own migration, so it's left for a follow-up. It would also close a race the derived order leaves open, in a history where no capture has a generation:
1. Retention claims an older capture's only backup.
2. That capture is re-uploaded before the prune finalizes.
3. The capture's first registration moves to the re-upload, after the newer capture's, so the restore would load the older capture.
Retention anchors a capture's first backup only while another backup of it exists when the claim is taken.

Severity and risk

Severity: high. A sandbox restored by order, which was almost every idle-suspended Kubernetes sandbox, could load an older capture than its latest, losing the user's work since then without an error.

Risk: medium.

Refusals. An unpinned sandbox whose history is unordered, and whose own node no longer holds its local copy, now refuses to restore (412, or a terminal refusal on the node) until it's pinned. Before, it restored something, possibly an older capture. During a mixed-version node rollout, that's a sandbox that suspended on an upgraded node and then on an older one, whose census or repair couldn't pin it.
An unbacked latest capture. An unpinned sandbox whose latest capture with a generation failed to upload still has no restore source until a backup of that capture or a later capture lands.
Named snapshots. An unpinned restore no longer loads a named snapshot's backup.
Drain holds. Compared with main, a drained node is held longer for unpinned rows. An evacuation-marked row holds it until its newest suspend capture is ready, or until the evacuating drain's re-upload and give-up resolve it. An unmarked row holds it only while a later upload is in flight, which ends when the node finalizes the upload or the stuck-snapshot reaper fails it. A failed upload never holds an unmarked row.
Query cost. The ordering adds correlated subqueries, scoped to one sandbox's snapshots, to the selector, the gates, the retention shield and the admin counts. Those plans cross jit_above_cost, so the service pools turn JIT off for their sessions, and the test Postgres runs with it off too.
Retention. Retention keeps the full snapshots registered up to a capture that makes a history unordered while it stays unordered, which costs storage for those sandboxes, and a rank-0 capture's first backup while its re-uploads remain.
Writes. The repair writes pins only when enabled, and the admin pin only on an operator's request, both under their guards.

Roll back by reverting this commit: the pins it writes name ready suspend captures, which the previous code restores as well.

Walkthrough

Snapshot registration now preserves each artifact’s first recorded capture generation. Restore selection uses capture rank, first registration order, and unordered-history checks across shared portability helpers and store queries. Direct, Kubernetes, and internal API restore paths consume the shared selector and map unordered outcomes to terminal refusals. The PR adds restore-pin state, admin endpoints, and an opt-in repair reconciler. PostgreSQL service sessions and test instances now disable JIT.

Merge Risk: Moderate · up to 26df0

The change restores sandboxes from pinned or capture-ordered sources and refuses ambiguous histories. Most earlier concerns are addressed with tests. Remaining gaps could, in narrow cases, restore an older capture or report a sandbox as durably restorable when it is not. These should be reviewed before merge or explicitly accepted.

Security architecture risk: Low · up to 26df0

The inspected restore-pin routes preserve administrator authorization and require an eligible artifact belonging to the selected sandbox. Repair is disabled by default and uses guarded writes. No security regression was established, but concurrency and upgrade or rollback behavior remain only partially verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

observed — The new capability uses existing managing-organization-administrator authority and can target sandboxes across organizations. Each write is bound to one resolved sandbox and an eligible capture of that same sandbox; the storage function does not independently enforce caller authorization.

Trust Boundaries and Controls

observed — The administrator controls the requested artifact ID, but SQL requires a ready full suspend capture with a live location belonging to the target sandbox and rejects provably superseded captures. The route also rejects conflicting, running, degraded, or unattributable local copies. Repair accepts only a usable suspended-node report and requires matching source-node backup provenance.

Resilience and Maintainability Implications

observed — Retention protects exact pinned artifact identity. Its prune claim locks the owning sandbox, then rechecks restore-source eligibility before moving a snapshot to deleting. This is concrete counterevidence against ordinary retention deleting an already committed pin's restore source; it does not establish every concurrent registration or pinning interleaving.

Explanation

The title does not match the required format. It starts with a bracketed area tag, [restore], which is allowed. The summary starts with the lowercase word 'order', which is allowed. The title describes the main change: ordering restore sources by capture rank, refusing unordered histories, pinning idle suspends, and adding pin repair. The raw summary and objectives confirm these changes. The title is 134 characters long, which is long but still specific. It contains no trailing period and no ticket IDs. It does not include a PR number, which is compliant.

Full details: Bug Fixes Name A Regression Test

Explanation

Applicability: This PR fixes a defect in application behavior under crates/. The contributor's "The problem" section says restore paths pick the newest backup by registration time, which can roll a sandbox back to an older capture. The check therefore applies. Validation section: It names specific regression tests that target the reported defect. I confirmed these test functions exist in the PR head: - a_new_backup_of_an_older_capture_never_outranks_a_newer_capture (crates/l30_storage/sandbox/store/src/restore_source/tests.rs). This matches the re-upload-of-older-capture rollback, and the scenario would select the wrong capture on the pre-fix ordering. - an_unpinned_restore_never_takes_a_named_snapshot (same file). - p14_markerless_latest_capture_is_shielded_from_later_re_uploads (crates/l40_api/snapshot/retention/src/tests.rs). - the_repair_pins_only_the_nodes_latest_capture (restore_pin_repair/tests.rs). - node_local_suspend_pins_only_its_executions_capture (published_state_tests/lifecycle_writers.rs). - service_pools_turn_jit_off (crates/l30_storage/postgres/pool/src/tests.rs). The Validation section also states that each new guard was mutated (24 mutations) and that a named test failed for each. I did not run the tests or the mutation checks, because the build toolchain is unavailable. The fail-without-fix claim rests on that statement and on the tests' scenarios matching the pre-fix behavior described in the PR. Verdict: The Validation section names regression tests for the defect, so the check passes.

Full details: Weakened Safeguards Are Justified

Explanation

No weakened safeguard found in the PR range refs/coderabbit/pre-merge-check/base..head (PR #1718, author the-gigi-pplx). Checks run: - Attributes: no #[allow], #[expect], #[ignore], #[should_panic] or lint-level changes were added or removed. - CI and config: no continue-on-error, SPACE_TEST_DEPS_OPTIONAL, nextest exclusions, allowlist or known-failure additions, or [lints] changes. ci/scripts/lib/test-deps.sh adds -c jit=off to the test Postgres. The only removed CI-file line is a comment that was extended. Cargo.toml adds a dev-dependency only. - Governance files: none of AGENTS.md, CLAUDE.md, CONTRIBUTING.md, docs/rust/ or .agents/ is in the changed-file list. The changed docs (docs/configuration.md, docs/execution-environments.md, admin CLI README) contain no review, merge-risk or approval guidance. - Removed test legacy_suspend_lookup_ignores_newer_non_suspend_full_artifacts (crates/l40_api/internal/api/server/src/tests.rs, ~line 6323): replaced in the same diff by suspend_lookup_returns_the_pinned_capture_over_newer_full_artifacts. It keeps the same assertion (the lookup returns the suspend capture, not a newer stop/snapshot-origin artifact) and adds a pin setup. This is an equivalent replacement. - Changed assertion in crates/l30_storage/sandbox/portability/src/drain_gate_differential_tests.rs (line ~29 of the hunk): the first expected value changes from true to false. That is a stricter release result, not a loosened one. The adjacent comment and the PR description state the new behavior, and the same test adds further assertions for the failed-upload and freshness cases. - Moved functions (fetch_restore_storage_uri, resolve_sandbox, with_target) are relocated or re-exported with pub(super)/pub(crate). They are not removed tests. No item meets a failure condition in the check.

Full details: Agent Tooling Runs No New Commands

Explanation

The check applies to agent plugin manifests, skills, and guideline files. The diff range (base to head, 74 changed paths) touches none of them. - Changed-file inventory: No path under .agents/, .claude/, or .codex/, and no AGENTS.md, CLAUDE.md, SKILL.md, plugin.json, or plugin.yaml appears in the diff. The changed files are Rust sources, SQL-backed tests, proto/node/api/v1/cluster.proto, Cargo.lock, ci/scripts/lib/test-deps.sh, and the docs/ and admin CLI README files. - Added-line scan: A search of all added lines for inline shell substitution (! followed by a backtick) and for agent-tool keys (hooks, mcp_servers, mcpServers, allowed-tools, lspServers) returned one hit. It is a Rust doc comment in crates/l30_storage/sandbox/store/src/restore_source.rs that mentions sql! in a code span. The check explicitly exempts this form. - Existing agent files: Agent plugin and skill files already exist in the head tree. The diff does not modify them. The test-deps.sh change adds -c jit=off to a Postgres start command. It is a CI script that the repository runs, not agent tooling, so it is outside this check's scope. No failing item was found.

Full details: Public-Safe Content

Explanation

I scanned every added line in the 74-file PR range (refs/coderabbit/pre-merge-check/base..head) and the PR title and description for the categories the check names. No finding. - Credentials, tokens, private keys: No password, secret, token or key literal values were added. The only password hit is a struct field binding in crates/l30_storage/postgres/pool/src/lib.rs around line 112, not a value. The token hits are local Rust variable names. A regex for quoted credential assignments returned nothing. - Internal hosts and URLs: No http(s):// URLs were added in the diff or the description. The IP-like values (127.0.0.1, 10.0.0.x, 100.64.0.12) appear only in test fixtures, and they are loopback or private-range placeholders. - Personal workstation paths: No /Users/ or /home/<name>/ paths were found. - Cloud account IDs and ARNs: No arn:aws or AWS key patterns were found. The 12-digit-number scan found only code and test UUID values. - Real cluster or environment names: No real cluster names were found. The description mentions "a Linux devbox", which is generic and not a sensitive identifier. - Private trackers, chats or documents: No links were found. - Production logs, measurements or incident details: The description reports local test counts (12961 unprivileged, 72 of 78 privileged). These are test results, not production data. The severity text describes a correctness defect that this PR fixes, which is not an undisclosed security vulnerability. The check does not fail on any of these categories.

[Should fix] The new unpinned arm of snapshot_is_live_restore_source shields every full snapshot that no restorable row outranks by generation. For any unpinned sandbox with at least one stamped row, that means every unstamped full snapshot, in every lifecycle, for as long as the row stays unpinned. full_snapshot_outranked_by_restorable(.., sn) is never TRUE when sn.generation IS NULL. Unstamped captures keep arriving after rollout too (inferred generations, startup recovery, re-uploads the node can't vouch for), so this is not only a one-time legacy backlog: on a long-lived unpinned sandbox retention can never prune them. The doc at 703-711 accepts this as "costs storage, not state", but nothing bounds it, and it can't be undone afterward without a cleanup pass.

The selector's pick is narrower than this set, and it is now deterministic. For every unpinned rule, select_restore_source loads the newest (timestamp, id) row among the ready, live-location full rows that nothing outranks. Under placement-fresh/newest-full it may also load nothing. Shielding just that row covers every selector. Suggested fix: add AND NOT EXISTS (SELECT 1 FROM snapshots later WHERE later.sandbox_id = {sandbox_alias}.id AND later.type = 'full' AND later.state = 'ready' AND EXISTS (<live location>) AND (later.timestamp, later.id) > ({snapshot_alias}.timestamp, {snapshot_alias}.id) AND NOT {full_snapshot_outranked_by_restorable(sandbox_alias, "later")}) to the arm. That holds the shield to about one row per sandbox, and the p14 cases still pass (in "mixed", gen 5 becomes prunable, which is correct because the unstamped row beats it). The old reason in the "Why neither arm narrows" section (no id tiebreak in the suspend selector) no longer holds now that select_restore_source orders by (timestamp, snapshot_id). If you keep the wide shield, add a test or metric that bounds it.

Agreed, fixed in 26df041. The unpinned arm now shields the selector's possible picks and no more. A full snapshot is shielded when no restorable suspend capture is newer than it by capture rank, then by its capture's first registration, ties broken as the selector breaks them. An outranked capture prunes by rank. Two arms keep what the order rests on, since it's derived from the rows that exist:

an artifact's first backup while its re-uploads remain and nothing outranks it, or while it ranks 0;

while a history is unordered, every row registered up to a capture that makes it so, so pruning can't turn a refused history into a chosen one.

An ordered history keeps nothing for its order. The doc comment describes each arm as it is.

[Question] A re-upload keeps its capture's place only while an earlier stamped backup of the same artifact still exists. Retention prunes old backups, and a disk eviction's upload-before-delete happens precisely when no backup is left. If the node can't vouch for the generation at that point, the re-upload of an old capture registers unstamped with the newest timestamp. Unstamped rows are never outranked, so for an unpinned row it beats the stamped latest capture in select_restore_source/no_newer_full_snapshot: the same rollback this PR is closing. Is the node guaranteed to keep the generation evidence for any artifact it re-uploads after its backup was pruned? If not, consider either (a) not counting an unstamped row registered after a stamped row as newer (treat it as outranked by any stamped row with a lower timestamp), or (b) keeping the artifact's generation somewhere that pruning doesn't delete (e.g. on the local-artifact record) so inheritance doesn't depend on a surviving snapshots row.

No, the node isn't guaranteed to keep that evidence, so the restore no longer depends on it. In 26df041, a capture without a generation registered after one with a generation is unordered against it unless a later execution's capture provably follows it. On Kubernetes that holds when the execution that took the later capture started (sandbox_k8s_executions.created_at) after this capture first registered. Direct keeps no execution history, so there a later-registered capture with a higher generation than every capture registered before this one still orders it. Off the sandbox's own node, an unpinned restore of an unordered history refuses explicitly instead of loading either: 412 from the API when nothing can restore it, and a terminal FAILED_PRECONDITION from GetSuspendSnapshotLocation, which sandbox-manager no longer retries. A history where no capture has a generation keeps its order. Re-uploads of one artifact order by that artifact's first registration. Separately, idle suspends now pin their capture, and a repair loop and an operator pin backfill pins, so most restores go by pin.

[Consider] The PR makes select_restore_source the single authority, but the admin runtime population (and the Direct source-node candidate in direct.rs) still spells out the same pick by hand: the pin preference, NOT outranked, placement freshness and the (timestamp, id) order. Today they match. But the selector's CTE form (outrank among candidates, then filter fresh) and this LATERAL form (filter, then order) are different shapes of one rule, and this file has no test in the diff. A small Postgres differential test would lock the agreement in: run the generation fixtures from restore_source/tests.rs (re-upload, mixed, failed-later-upload, pinned) through sandbox_population and select_restore_source and assert they choose the same snapshot id. That catches drift the next time either side changes.

Added in 26df041: the_population_binds_the_capture_the_selector_restores runs the selector's histories (re-upload, unordered, ordered by a later capture, from before generations were recorded, no generation at all, each with a late re-upload of its first capture) through both sandbox_population and select_restore_source, and asserts the population binds the selector's pick, or counts the sandbox unrecorded when the selector refuses or finds nothing. The population refuses unordered histories outside the pin, as the selector does.

[Consider] Two comments use historical framing: "registration time decides as it always did" here, and "so they compete on timestamp as before" in the module docs (line 124). State the current rule instead, e.g. "registration time decides" / "so they compete on timestamp".

Fixed in 26df041. Both comments state the current rule.

[Consider] The comment says the node asks only once a restore has claimed the row. RestoreRetrySource::WhenRestoring and the proto docs also cover a node recovering a started sandbox whose runtime was lost, and the p14 "started" retention case shields for exactly that. Suggested wording: "The node asks on behalf of a restore the control plane already started (a claimed restore, or recovery of a started sandbox), so a restoring row selects from the claim's source window."

Fixed in 26df041, with your wording: the node asks on behalf of a restore the control plane already started, a claimed restore or the recovery of a started sandbox, so a restoring row selects from the claim's source window.

94-94: Trivial · Maintainability & Code Quality · Quick win

Spell out the unretired-upgrade phase list in each statement instead of interpolating UNRETIRED_UPGRADE_PHASES_SQL.

The data-store guideline says to keep every SQL statement whole and reviewable at its query site. It also forbids interpolating partial SQL strings, including comma-separated value lists. The listed exceptions are the portability predicate, the residency fragments, and the table column list. A phase-name list is not one of them.

The same interpolation is in these places:

Line 94 and line 207 of this file.

eviction_scan.rs, line 110.

runtime_upgrades.rs, lines 359-360 and 376.

Each site needs a format! only because of this constant. After the change, each &format!(...) wrapper becomes a plain &str, and the constant and its import can go.

Drift risk is already covered. a_suspended_eviction_claim_waits_for_an_unretired_upgrade checks the claims against unretired_runtime_upgrade. That test does not cover the eviction_scan.rs candidate scan. Add a scan case to it, or accept that the scan is the one unpinned copy.

The doc comment on that test says "The claim spells its phases out". That is wrong after this change. Update it when you make the edit.
Proposed change (apply at each site)
-               AND phase IN {UNRETIRED_UPGRADE_PHASES_SQL}
+               AND phase IN ('fenced', 'preserved', 'booting', 'verified')
The OpenGrep format! hints on lines 82-114 and 192-235 are false positives for injection. The interpolated value is a const, not external input. The guideline concern above still applies.

As per path instructions (crates/**, "Develop and inspect SPACE data stores"): "Keep every SQL statement syntactically whole and reviewable at its query site. Do not build a statement by factoring out or interpolating partial SQL strings".

SubstrateAdapter::node_api_target and keep it as a required method with the
existing signature. Preserve the implementations in DirectSubstrate and
KubernetesSubstrate and the forwarding behavior in Substrate so missing
implementations fail at compile time rather than returning Unsupported at
runtime.

The problem

When a suspended sandbox wakes, the control plane picks which full snapshot to restore. Every path picked "the newest" by snapshots.timestamp, which is when a backup attempt registered, not when its bytes were captured. A later re-upload of an older capture, such as the drain re-upload queue or an eviction's upload before delete, therefore won, and the sandbox silently rolled back. The three selectors also disagreed, and only API suspends pinned the exact artifact.

Example

sandbox S, unpinned (idle suspends), full + ready rows:
  S1  artifact A  generation 4  10:00   suspend #1
  S2  artifact B  generation 5  11:00   suspend #2, the latest work
  S3  artifact A  re-upload     12:00

main:      newest timestamp -> S3 -> A: the 10:00-11:00 work is lost, no error
this PR:   S3 inherits generation 4, S2 outranks it -> B
           an unstamped row after a stamped one, with no later stamped capture, is "unordered":
           an unpinned restore off the sandbox's own node now refuses (412 / FAILED_PRECONDITION)

Below, "stamped" means a row that records a capture generation, and "unstamped" means one that doesn't.

Verdict: request changes

The shared selector, generation inheritance under the per-artifact lock, idle-suspend pins and the repair loop are the right fix, in the right layer, and ordering by first registration is the right rule. CI is green at eb916ee: the jit=off amend cleared the duration-gate failure.

The problem is how the order is computed. Nothing stores it: every read rebuilds it from the sandbox's whole snapshot history.

capture_registered_at is a MIN(timestamp) over the artifact's backups.
capture_rank nests it inside EXISTS and NOT EXISTS over earlier and later stamped rows.
By our count, one no_newer_full_snapshot check expands to about 19 correlated subqueries, up to four levels deep, and about 20 files interpolate fragments that now carry them.

That's why the plans crossed jit_above_cost. It's also why retention now has to keep the rows the order is derived from (arms 4 and 5).

The unordered refusal sits on top of that. restore_order_unordered is ANDed into about ten shared portability fragments. Other components read those fragments for other questions: whether a suspend is finished, whether any durable copy exists, whether a row may be unpinned, whether a snapshot may be pruned. Unstamped captures after stamped ones keep arriving: from nodes without stamping during a rollout, from startup-recovery adoptions, and from re-uploads of unrecorded captures. On several paths the refusal then leaves a sandbox stuck (started, failed or refused), and the system has no supported way to unstick it. Items 1 to 6 below all come from that one choice.

What we'd like instead:

Pin first. Make the pin the normal restore path, so ordering is only a fallback for legacy rows.
- This PR's idle-suspend pins and repair loop go most of the way.
- Also pin when the node's census reports its suspended artifact, even for an unstamped capture. Use repair_restore_pin's guards: a ready backup of that artifact from that node, registered since the suspend began, and no other artifact's capture registered after it. Today such a capture is left unpinned, which is how a node-local suspend ends up unpinned and unordered.
- Cover Direct suspends too. Today's proof uses the Kubernetes execution's generation.
Store the order key when the row is written. Add a snapshots.captured_at column. snapshot_store::insert sets it under the advisory lock it already takes for generation: from the earliest existing backup of the same artifact, else the row's own registration time.
- Readers then compare a column instead of running MIN subqueries.
- Pruning a first backup no longer moves a capture, so retention arm 5's first-backup anchor goes away.
- Cost:
  - a nullable column;
  - a batched one-time backfill (MIN(timestamp) per artifact over the existing rows);
  - readers falling back to today's derivation while the column is still NULL during the rollout.
- Limits: it doesn't by itself order an unstamped capture against stamped ones. An artifact whose backups were all pruned still gets a fresh key when it is re-uploaded. generation keeps that role.
Resolve legacy ambiguity once, not on every read. Drop the unordered refusal from this PR.
- An unordered history then restores its newest capture by first registration. That's the rule this head already uses for a history with no stamped capture, and it's much like main, where the later registration wins.
- If a refusal is still needed after 1 and 2, put it in its own PR, in the selector only, with an operator way to pin a capture.

Items 1 to 6 below go away under this shape. The rest still apply, though item 8 shrinks once the refusal is gone. If you'd rather keep the refusal here, items 1 to 6 each need their own fix, and the next consumer of these fragments meets the same question.

Before merge (inline threads)

An idle suspend whose capture is unstamped after a stamped one never finalizes, so the row stays started
The drain's ArtifactMissing give-up and the drained-node terminator now fail unordered unpinned rows that have durable backups
A refused sandbox has no supported way out, and the message tells callers to "pin the capture"
Node eviction deletes the local copy that an unordered row's only restore path needs
Markerless quarantine recovery bypasses the refusal and picks one side of an unordered history
A failed restore's pod cleanup unpins a pinned row whose history is unordered
The rank-0 rule trusts first registrations that survive, so a history missing its anchor can be ordered wrongly
Retention arm 4 keeps rows permanently, in ordered and pinned histories too
The selector's unpinned rule silently drops GetSuspendSnapshotLocation's suspend-origin filter
The selector builds its SQL at run time from partial fragments
The description
The "latest capture" wording overstates placement-fresh
How a refusal reaches the caller depends on the substrate and the node's state
Tests that no longer prove their names
The repair treats a later named-snapshot backup as "the sandbox ran since"

Follow-ups

scripts/admin/prune_cluster_artifacts.py still keeps the newest row by timestamp (:1009). Its "must stay identical" docstring covers only the pin predicate.
The smoke harness's RESTORE_PORTABLE_SQL (space_smoke/adapters.py) mirrors the old placement-fresh rule.
JIT:
- The service pools now force jit=off. Mention it in docs/configuration.md's Database section.
- A role-level ALTER ROLE … SET jit = off would reach every connection path.
#1502 sets a backup's source_node_id to the pod's node. The repair requires that to equal the placed node, so those rows won't be repaired (it fails closed).
#1714 also adds a required adapter method, so whichever PR lands second adds the other's stubs.
Repair counters (pinned, unrepairable) would make "until the unpinned population stops shrinking" observable.

Nits

Stale or contradicting comments:
- Kubernetes "Terminal: no node-only fallback either" (kubernetes/store/restore_source.rs:184): its caller does fall back to the node.
- RestoreRetrySource says "ignoring the pin".
- The repair module docs call it Kubernetes-only.
- "used to finalize" narrates history.
- newest_full_snapshot_unambiguous says "by timestamp".
restore_pin_repair.rs:84's "one statement … serializes it" claim: the snapshots EXISTS reads the statement's snapshot after waiting on retention's row lock. This is harmless today, since the shield and the repair agree except on an exact tie of first-registration times. Say so, or re-check in a second statement as retention does.
Repair config and logging:
- SPACE_RESTORE_PIN_REPAIR_ENABLED accepts only 1/true, so on and yes read as off.
- The batch size has no ceiling.
- Ok(false) always logs "isn't the latest capture".
- A node whose node_direct row is deleted is retried as "unreachable" forever.
an_ambiguous_restore_source_is_permanent_not_a_retry_response iterates Some(uri), which never reaches GetSuspendSnapshotLocation.

The earlier review's five open threads look addressed at this head. The rank-0 question in item 7 is what's left of the second one. They still need resolving before the merge queue takes this.

An idle suspend whose capture is unstamped after a stamped one never finalizes, so the row stays started. crates/l30_storage/sandbox/portability/src/lib.rs:2061

What's wrong: the PR added NOT {unordered} to newest_suspend_snapshot_current_with_guards. That feeds started_suspend_revert_eligibility().eligible, which both node-local finalizations require: the backup-ready projection (published_state.rs:2726) and the census (sandbox_quarantine_store.rs:777).

Scenario: a stamped capture (generation 5) is followed by an idle suspend whose upload is unstamped. The row is unpinned, or its pin is the previous cycle's.

Neither path finalizes. The control-plane row keeps started and its execution while the node holds the sandbox suspended.

The repair loop never sees the row, because it only looks at suspended rows.

On main the row finalized suspended.

Test gap: node_local_suspend_pins_only_its_executions_capture misses this, because its earlier capture is unstamped or stamped higher (the history is ordered).

Fix: give the two projections an eligibility without the unordered clause. Finalizing a suspend doesn't choose a restore source. The orphan-recovery and missing-pod reverts, which unplace the row, can keep it. Then add a stamped-then-unstamped case through both by_report values.

Agreed, fixed in 26df041. Both node-local finalizations, the backup-ready projection and the census, now use started_suspend_finalize_eligibility, whose markerless arm doesn't refuse an unordered history. Finalizing records the node's suspend, so the row reaches suspended while the node holds the sandbox. The orphan-recovery and missing-pod reverts, which unplace the row, keep the refusal. The census also pins that capture from the node's report (the review body's point 1), so such a row restores by pin. node_local_suspend_pins_only_its_executions_capture gains a stamped-then-unstamped case through both by_report values. It finalizes either way, pins only from the report, and fails with either finalization reverted.

The drain's ArtifactMissing give-up and the drained-node terminator now fail unordered unpinned rows that have durable backups. crates/l30_storage/sandbox/portability/src/lib.rs:2154

What's wrong: mark_sandbox_lost_query (drain.rs:729) and mark_unrecoverable_sandboxes_lost_query (lost.rs:245) write lifecycle = 'failed' on NOT snapshot_durable_for_source_release. That predicate is now false for every unpinned unordered row.

On main such a row stayed suspended and restorable. Now it ends up failed:

out of the repair loop;

not revertible by the failed-repair path, because newest_suspend_snapshot_activity_current refuses it too.

Neither flip has a test.

Fix: give the give-ups an "any durable copy exists" rule, and keep the unordered clause on release gates only.

Agreed, fixed in 26df041. The two questions are now separate predicates. snapshot_durable_for_source_release keeps its refusal of an unpinned unordered history, and for an unpinned row it requires a suspend capture the restore would load. snapshot_durable_copy_exists asks only whether a durable copy remains: for an unordered history, any ready one. The drain's ArtifactMissing give-up and the drained-node terminator use the copy rule alone. Such a row stays suspended with its durable copies, and still blocks source release until it's pinned. The terminator's doc says so. New cases in mark_lost_fails_only_suspended_rows_without_a_durable_copy and drained_node_mark_lost_keeps_an_unordered_history_with_durable_copies fail with the old predicate restored.

A refused sandbox has no supported way out, and the message tells callers to "pin the capture". crates/l30_storage/sandbox/store/src/restore_source.rs:145

The message reaches users in the 412 body. snapshot_restore.rs:144, restore_pin_repair/mod.rs:229 and docs/configuration.md:58 say the same thing.

Nothing lets an operator pin. artifact_marker::set_current_local_artifact has one caller, the API suspend handoff.

The other two exits don't help:

The repair pins only while the placed node still holds the sandbox, which is exactly when the own-node restore already works.

"A later stamped capture" needs the sandbox to run.

Fix: add a guarded store verb, plus an admin route and a runbook entry, to pin a named ready suspend artifact. Guard it on suspended, unpinned, and an unchanged lifecycle_changed_at.

If that's out of scope: reword all four texts so they don't name an action nobody can take, and say in "Not covered" that such a sandbox has no exit. For example: "refusing to restore sandbox {id}: its captures can't be ordered (a capture with no recorded capture generation registered after one with a generation), so the control plane won't guess which is the latest."

Agreed, fixed in 26df041 with a guarded verb, an admin route and a runbook entry.

restore_pin::pin_restore_source pins only a suspended, unpinned row whose lifecycle_changed_at is unchanged since the read. It pins only a capture the selector could take: a ready full suspend backup with a live location that no capture still uploading or ready outranks, and that no later capture of the same rank follows, unless that later upload failed. In an unordered history that's the latest capture of each side.

GET /admin/api/v1/sandboxes/{id}/restore-pin lists those captures with the lifecycle_changed_at token, and POST pins one, or answers 409. Before pinning, it asks the sandbox's node what it holds: a node holding the sandbox suspended restores its own local copy whatever the pin names, so the pin is refused while the node holds another capture.

The runbook is "Restore refused: captures can't be ordered" in the admin CLI README.

The 412 body, sandbox-manager's error, the repair's log and docs/configuration.md now name that route. an_operator_pins_either_side_of_an_unordered_history_and_nothing_older covers the guards.

Node eviction deletes the local copy that an unordered row's only restore path needs. crates/l40_api/sbx/mgr/server/src/sandbox_eviction.rs:471

What's wrong:

decide evicts a node-pinned copy on its backup marker alone.

The unpinned proof is_latest_ready_suspend (snapshot/store/src/lib.rs:847) still orders by timestamp and doesn't know about unordered histories.

After an eviction, both substrates' own-node paths have nothing to load, and GetSuspendSnapshotLocation refuses. The sandbox can't be restored. On main, the off-node restore loaded the newest row.

Fix: require DurablyRestorable before evicting a suspended copy. That's a node change: older nodes keep evicting during a rollout, and those sandboxes keep their disk. Or remove the population, as in the suggested shape.

Agreed, fixed in 26df041, on both sides.

Node. Before evicting a suspended copy, eviction now also asks DurablyRestorable, on the tick's cluster connection. A sandbox the cluster can't restore without the copy is skipped as no_backed_copy. That covers a node-pinned copy with its backup marker, the case you named.

Server. is_latest_ready_suspend, the unpinned proof, is never true for an unpinned row whose history is unordered. That keeps nodes that predate this PR from evicting such a copy through the unpinned path.

An older node still evicts a node-pinned copy on its marker alone during the rollout. The rollout section says so. Tests: eviction_keeps_a_backed_up_copy_the_cluster_cannot_restore_without and the_unpinned_eviction_proof_refuses_an_unordered_history.

Markerless quarantine recovery bypasses the refusal and picks one side of an unordered history. crates/l30_storage/sandbox/portability/src/lib.rs:1183

What's wrong: PRE_QUARANTINE_SNAPSHOT_QUERY (sandbox_quarantine_store.rs:155, used at :291) builds on quarantine_recovery_suspend_snapshot_current. That fragment now ranks by capture but has no unordered check.

Example, with rows B1 (artifact b, gen 5, t10), A1 (artifact a, unstamped, t20) and B2 (artifact b, gen 5, t30):

A1 counts as current: it has no rank, nothing outranks it, and no capture registered later.

The shared selector refuses this history, and main picked B2.

So the body's "one rule on every path" doesn't hold here.

Fix: apply the same refusal to the markerless arm. The exact-artifact arm can stay as it is.

Agreed, fixed in 26df041. pre_quarantine_suspend_snapshot_current now refuses an unordered history. The exact-artifact arm is unchanged. pre_quarantine_recovery_refuses_an_unordered_history runs your B1/A1/B2 history and expects the plan refused.

The description.

Rollout says "Most sandboxes avoid it, because an idle suspend on an upgraded node pins its capture", and "its unpinned restore refuses until …". Both are false for the older-node suspend they describe (item 1).

"Answered 412 by the API" holds only on some paths (item 13).

The refusal's outcome is stated per path. The selector tests are described as new, and the counts are from the branch's latest full workspace run.

The "latest capture" wording overstates placement-fresh. crates/l30_storage/sandbox/store/src/restore_source.rs:38

Placement-fresh and the gates built like it aren't held back by a later capture of the same generation that is still uploading or has failed (full_snapshot_outranked_by_generation compares >).

That matches main. But it contradicts the docs here and the headline "never loads an older capture … when it can tell them apart".

A wording fix is enough: only a later execution's capture holds the restore.

Fixed in 26df041's wording. Only a later execution's capture holds the restore. A later capture of the same execution that's still uploading doesn't, as on main.

How a refusal reaches the caller depends on the substrate and the node's state. crates/l40_api/api/src/controllers/substrate/direct.rs:2940

Direct, when the source node is present but lacks the copy: sbx-mgr's FAILED_PRECONDITION passes should_try_next_restore_candidate (direct.rs:384). The restore ends in the retryable Unavailable (direct.rs:3527), not the terminal 412.

Kubernetes: restore_source_node_name falls back to the newest execution's node with no liveness check (kubernetes/store/restore_source.rs:44). An unordered sandbox whose node is gone gets a node-only pod that never becomes ready, so it sees 503s instead of the refusal (PLAUSIBLE).

Direct, when the source node is only cordoned or stale: there are no candidates, so the restore answers a terminal 412 for a transient condition (PLAUSIBLE).

Fix: carry a distinguishable refusal through the node RPC and map it before the candidate-retry check. Refuse when the named node isn't a live worker. Then state the per-path outcomes in the body and the proto comment.

Fixed in 26df041.

Direct, node lacks the copy. sandbox-manager tags its refusal with x-space-restore-refusal: source-unordered. should_try_next_restore_candidate and restore_status_error read it, so the restore ends in the terminal 412.

Kubernetes, source node gone or not ready. When the remote source is refused, the restore falls back to the source node only while that node is registered and ready. A registered node that isn't ready answers a retryable 503, and a missing one the 412.

Direct, source node only cordoned or stale. With no candidates, a node that's still registered answers a retryable 503. Only a sandbox with no source node gets the 412.

The body lists the outcome per path. Tests: restore_retries_node_local_candidate_errors, plus new cases in both an_unordered_history_restores_only_* tests.

Fixed in 26df041. The elsewhere guard, now in the shared node_held_capture_is_latest, counts only suspend and NULL-origin rows. It also refuses an exact tie of first registrations, so the repair and retention's shield can't disagree about which capture is the latest. The repair test gains a later named-snapshot case.

Minor · Functional Correctness · Quick win

Map unordered restore sources to the shared status on interrupted retries.

On an interrupted cross-node restore retry, run_cross_node_restore can receive no URI from either the request or the persisted row. It then calls restore_pull_metadata_scoped, which can return RestoreSourceUnordered. resume_interrupted_stage has no arm for that variant, so its other arm returns Status::unavailable. The initial restore handler returns the shared unordered-source status instead. The comment at crates/l40_api/sbx/mgr/server/src/service/recovery_cross_node.rs:1429-1431 says UNAVAILABLE makes callers retry a refused restore indefinitely, so this retry path can repeat a refusal that needs repair.

Add the same mapping before the other arm:
Suggested fix
             error if error.is_stopped_materialization_refusal() => {
                 Status::failed_precondition(error.to_string())
             }
+            error @ crate::snapshot_restore::RestoreError::RestoreSourceUnordered(..) => {
+                pplx_space_sbx_mgr_client::restore_source_unordered_status(error.to_string())
+            }
             other => Status::unavailable(format!(
                 "resume interrupted cross-node restore staging failed: {other}"
             )),
Cover this retry path with a regression test at the owning layer.

rather than planning a restore on the selected node; preserve the current

- Line 125: Update the CAPTURES projection in restore_pin_state to report the
same per-artifact generation used by capture_rank when sn.generation is absent.
Match sibling snapshots by sandbox, type, local artifact ID, and null-safe
artifact kind, while preserving the existing eligibility and newest-backup
selection behavior.

Review comments at @crates/l40_api/api/src/controllers/sandbox/mod.rs:
- Around line 1202-1205: Bound the complete admin pin node-check flow—including
endpoint resolution and the call to sandbox_state_with_node_api—to the API
handler’s roughly 10-second latency target; the existing 30-second RPC timeout
alone does not bound the sequential work. Ensure a timeout across either step
lets the handler return its existing 503 response.

Review comments at @crates/l50_app/admin/cli/README.md:
- Around line 318-319: Update the Direct restore documentation to include the
case where the source node remains registered but cannot take the restore:
Direct returns Unavailable, mapped to HTTP 503, with the unordered-capture
message. Preserve the documented 412 case and distinguish the two refusal
conditions.
- Around line 322-323: Update the restore-pin repair section around
SPACE_RESTORE_PIN_REPAIR_ENABLED to state that automatic pinning occurs only
when node_held_capture_is_latest holds, and that a later capture of another
artifact or a higher-generation full snapshot leaves the row unpinned. Extend
the manual pin guidance to cover both this repair outcome and when the node no
longer holds the capture.

snapshot row, evaluate eligibility only after both locks are held, and perform

- Line 2281: Update the source-release eligibility check around
snapshot_durable_copy_exists to require a selectable suspend-origin capture that
satisfies the restore selector’s capture-order rules; keep broader durable-copy
preservation separate for give-up decisions. Extend
an_unpinned_restore_never_takes_a_named_snapshot with a source-release assertion
in its later-execution case, testing at the lowest layer that catches the
regression.
- Line 2329: Update the unmarked-row ordering condition around `{outranked}` to
apply unordered-history preservation before freshness and generation
restrictions, so a ready durable capture is not rejected when later captures
failed. Preserve the outer release guard, and extend the ordering-history table
at the lowest layer that exercises this condition to cover the described
failed-later-captures case.

Major · Data Integrity & Integration · Quick win

Restrict the retry durability check to the pinned source when a pin predates the claim.

Before a restore claim, a pinned artifact limits the retry source to that pinned backup. restore_retry_source_snapshot_exists still accepts a different ready capture through its source_is_current arm. Its durably_restorable result is then true, while Retry and NodeLookup return no source. A pinned sandbox whose pinned backup failed, with a ready newer capture in the window, is reported as durably restorable even though the restore refuses it.

Apply the same pin_pre_claim restriction to the predicate. Build the fragment as restore_source.rs does at line 276. Then the source_is_current arm applies only when no pre-claim pin exists:
Suggested fix
-                AND (({source_is_current} AND ({pinned} OR NOT {unordered}))\n\
+                AND (({source_is_current} AND NOT {pin_pre_claim} AND ({pinned} OR NOT {unordered}))\n\
                      OR ({pinned} AND {window}))\n\
Define pin_pre_claim in this function from the same claimed_pin expression that restore_source.rs uses at line 276. The pinned-and-window arm keeps the pinned artifact as the only source in that case.
Add a negative assertion to the restore-source test for this scenario. It should check that durably_restorable returns false when the pinned backup failed and only another capture is ready.

- Line 1138: Update the Direct-sandbox ranking logic in capture_rank_where so
registration order alone cannot rank a no-generation capture as newer or older
than a generated capture when first uploads may be delayed. Establish an
ordering signal independent of registration time, or add an explicit refusal
rule that prevents unsafe unpinned restores while keeping valid legacy
pre-generation histories restorable; add regression coverage for both histories.

…n, refuse unordered histories, pin idle suspends, and repair pins

CodeRabbit: Dismissed by CodeRabbit

the-gigi-pplx · 2026-11-13T20:18:25Z

Thanks, this is a careful review. We kept the unordered refusal, and fixed items 1 to 6 each in place, with a test for each. The refusal is what keeps a restore from loading an older capture when nothing can order the two, and data loss is the one outcome we rank above a stuck sandbox. What made the refusal costly was where it applied: it reached fragments that finalize a suspend, give up on a node, or unpin a row. In 26df041 it stays only where a restore source is chosen, a source copy is released, or a pin would be cleared. Finalizing and the give-ups now use variants without it, and a refused sandbox now has an exit. Taking your three points in turn:

Pin first. Done, with your guards. A node-local suspend's census now pins a capture without a generation that the node reports holding, when its backup from that node registered since the suspend began, nothing outranks it, and no other suspend capture registered at or after it (node_held_capture_is_latest, shared with repair_restore_pin). The repair loop covers Direct as well as Kubernetes, and the operator pin in item 3 covers the rest.
A stored order key. Not in this PR. A new snapshots column needs its own migration PR, and the repo requires migrations to land on their own. The column also wouldn't remove the rank-0 problem in item 7, which we've fixed differently (see there). I'd like to take captured_at as a follow-up once this lands, and I'll ask before opening it.
Drop the refusal. We'd rather keep it. With it dropped, an unordered history restores its newest capture by first registration, which can be the older state: the case this PR exists to stop. The cost you describe is real, and the fixes for items 1 to 6, answered on their threads, remove it. A refused sandbox now has a supported exit, and its row is never failed or unpinned because of the refusal.

Follow-ups and nits from the review body

Nits. All fixed in 26df041:
- the Kubernetes "no node-only fallback" comment;
- RestoreRetrySource's "ignoring the pin" (the type is gone);
- the repair docs, which now cover both substrates;
- "used to finalize";
- newest_full_snapshot_unambiguous's ordering;
- the repair's "one statement serializes it" claim, which now says what the snapshot reads see and why it's still safe;
- SPACE_RESTORE_PIN_REPAIR_ENABLED, which takes the shared flag vocabulary;
- the batch, which is capped at 1000;
- the refused pin's log, which now names both causes;
- a Direct node with no node-api endpoint, which is now reported unrepairable rather than retried.
JIT. docs/configuration.md's Database section now describes jit = off. A role-level setting is a deployment choice, so it isn't in this PR.
[teardown-backup] attribute a cross-node restore pod's teardown backup to its pod node and re-ask a refused source node #1502 and [api] upgrade a stopped sandbox's runtime in place without starting it, and owe its disk backup #1714. Noted: the repair fails closed on [teardown-backup] attribute a cross-node restore pod's teardown backup to its pod node and re-ask a refused source node #1502's rows, and whichever of [api] upgrade a stopped sandbox's runtime in place without starting it, and owe its disk backup #1714 and this PR lands second adds the other's adapter stubs.
Not in this PR: prune_cluster_artifacts.py, the smoke harness's RESTORE_PORTABLE_SQL, and repair counters. Each changes another surface; I'll ask before filing them.
