Summary

The store half of per-attempt runtime upgrade finality: three sandbox-manager migrations and the store functions that record and read each attempt's outcome, keyed by (operation_id, attempt_id). Sandbox-manager now records the attempt every UpgradeRuntime runs as: the request's attempt_id, or an id it generates when the request names none. Nothing reads the records back on the wire until the next pull request, and no caller's behavior changes beyond the migrations.

Terms

• Attempt id: the opaque id an UpgradeRuntime call runs as (UpgradeRuntimeRequest.attempt_id). The caller keeps it across retries of one attempt and picks a new one for a replacement attempt; a Kubernetes substrate derives it from the pod UID. The node generates one when the request names none.
• Outcome: what an operation ended in, in sandbox_runtime_upgrade_outcomes: rolled back, already on target, or, new here, refused.
• Refused attempt: a started target's call that failed after the operation reached its target, for example because the sandbox runs another attempt's execution.

The problem

A caller retries a failed UpgradeRuntime under the same attempt id, and the store kept only the operation's latest outcome, with no attempt. Nothing could tell one attempt's rollback from another's, and nothing could answer an attempt's retry with that attempt's own outcome. The next pull request makes rollbacks and refusals final per attempt; it needs the store to record them per attempt first.

How this fixes it

• 20261112170001_sandbox_runtime_upgrade_attempt_id: a nullable attempt_id on sandbox_runtime_upgrades and sandbox_runtime_upgrade_outcomes. Only rows written before it read as naming no attempt.
• 20261112170002_sandbox_runtime_upgrade_refused_attempts: each attempt refused after its operation reached its target, keyed by operation and attempt id.
• 20261112170003_sandbox_runtime_upgrade_attempt_outcomes: each attempt's rollback or refusal, keyed by operation and attempt id, so a later attempt's outcome never erases an earlier attempt's.
• Store writers (crates/l30_storage/sbx/mgr/store/src/db/runtime_upgrades.rs), each taking the attempt id:
  • begin_runtime_upgrade and record_runtime_upgrade_already_on_target record the attempt, and the operation's outcome names its latest attempt.
  • finish_runtime_upgrade_rollback also adds the rollback to the attempt's history, keeping an attempt's first.
  • record_runtime_upgrade_refusal records a refused outcome. It replaces an earlier attempt's rollback or refusal under the same request, but never an already-on-target outcome, a live row, or another request's outcome.
  • record_runtime_upgrade_refused_attempt records a refused attempt only once the operation reached its target for that sandbox: its live row is retired, or it has no live row and an already-on-target outcome. An attempt's first refusal is kept; recording it again changes nothing.
  • new_runtime_upgrade_attempt_id generates a fresh id (a UUIDv7).
• Readers: read::runtime_upgrade_attempt_outcome and read::runtime_upgrade_refused_attempt read an attempt's own rows back. The report names the attempt of its outcome and the operation's latest refused attempt, ordered by insertion, since refused-attempt rows are never rewritten.
• Sandbox-manager (crates/l40_api/sbx/mgr/server/src/service/runtime_upgrade.rs): UpgradeRuntime runs as the request's attempt_id, or a generated one when it names none; an empty one is INVALID_ARGUMENT. A Wake names no attempt, so its upgrade runs as a fresh, generated one. The fence and the already-on-target record both write that id.
• Deleting a sandbox deletes its refused-attempt and attempt-outcome rows (delete_sandbox_child_rows). The eighth pull request of this stack keeps them instead.

Validation

• Store runtime_upgrades::tests:
  • the_report_names_the_attempt_each_outcome_was_recorded_for: the attempt each outcome names, and that a refusal is refused for another target state, target, authorization or sandbox.
  • each_attempts_rollback_or_refusal_is_kept_for_that_attempt: each attempt keeps its first rollback or refusal, and a live row written before attempts were recorded adds none.
  • a_refused_attempt_is_recorded_only_for_an_operation_that_reached_its_target: a refused attempt is recorded only for a retired upgrade, or an already-on-target outcome of the same sandbox with no live row. An attempt's second refusal changes nothing, and each operation reports its own latest refused attempt.
• Sandbox-manager runtime_upgrade::tests:
  • requests_are_parsed_strictly: an UpgradeRuntime that names no attempt gets a node-generated id, unique per request; a named one is kept; an empty one, or one over 256 bytes, is INVALID_ARGUMENT.
  • an_upgrade_records_the_attempt_it_ran_as: the report names the attempt the upgrade ran as.
• pplx-space-db-migrate tests:
  • runtime_upgrade_migrations_follow_their_predecessors_and_round_trip: the three follow 20261112160000, the newest sandbox-manager migration before them, sit next to each other, revert newest first, and round-trip up, down and up twice.
  • runtime_upgrade_downs_refuse_while_a_row_an_older_release_misreads_is_recorded: each down refuses while its guarded row is recorded, stays applied, and goes through once the row is gone. A rolled_back outcome doesn't hold back the attempt id's down.
  • suspend_attempt_rollback_preserves_ownership_and_migration_history now steps back past newer migrations before it tests 20261112160000's own down.
• Each new guard and each attempt-id path was mutated, one at a time. Every mutant fails a test, with three exceptions:
  • INSERT OR REPLACE on refused attempts behaves the same as the original, because the upsert clause handles the key conflict first.
  • The two new deletes in delete_sandbox_child_rows are covered by ON DELETE CASCADE. They're registered there as the store's AGENTS.md requires.
• ci/scripts/run-rust-checks.sh clippy, tests-unprivileged and tests-privileged on a Linux build box:
  • Clippy, doctests, the M1 SDK check and feature isolation pass.
  • Nextest: 12853 of 12854 unprivileged and 72 of 78 privileged pass. All seven failures are in crates this doesn't touch, and all come from the box: three need fs-verity, which its kernel lacks; two reject the box's non-root-owned path ancestors; one needs a private cgroup namespace; and node-mgr stopped_unbound_snapshot_reaches_filesystem_without_allocating passes in CI's Rust tests job.

Not validated: a Kind smoke at this head before CI runs it.

Dependencies

PR #1753, the split below this one and its stacked base. This merges after it.

Rollout

A sandbox-manager from this release applies the three migrations at startup, and an older one refuses a database whose history holds a version it doesn't bundle, so a rollback build keeps them, as db/README.md requires.

The down migrations are guarded:

• 20261112170003's refuses while any attempt's outcome is recorded.
• 20261112170002's refuses while a refused attempt is recorded.
• 20261112170001's refuses while a refused outcome is recorded, since an older release can't parse one.

Every rollback now records its attempt's outcome, and those rows are deleted only with their sandbox, so once a node has rolled back an upgrade, a schema rollback waits until that sandbox is deleted. 20261112170001's down drops the attempt id of a live upgrade row without a guard; that upgrade then behaves as it does on a release without per-attempt finality.

Not covered

• Nothing answers a retry from an attempt's own records yet, and UpgradeRuntime and GetRuntimeUpgrade don't put the attempt fields on the wire. PR [sbx-mgr] make a runtime upgrade rollback or refusal final for its attempt #1755, the next split, adds both.
• record_runtime_upgrade_refusal still records a refused outcome for an attempt that already has its own rollback or refusal. The attempt's history keeps its first, so the operation's report can then name that attempt with another status and failure than its retries get. The writer's doc makes that the caller's precondition, and the stack's only caller answers a settled attempt before recording anything. The cost would be a misreported status, not lost data. The store fix is about 10 lines: in the same transaction, return false when sandbox_runtime_upgrade_attempt_outcomes already holds a row for the operation and attempt.

Severity and risk

Severity: does not apply on its own; it's the storage the next pull request needs.

Risk: low. The migrations only add a nullable column and two tables, and nothing reads the new records on the wire until the next pull request. A binary rollback keeps the schema, and an older binary never reads the new tables. Roll back the code by reverting; the schema stays.

Walkthrough

Runtime-upgrade requests now use attempt IDs that are generated when omitted and validated when supplied. Storage associates attempt IDs with upgrade records and outcomes, retains per-attempt rollback and refusal history, and includes this information in reports. The RPC maps refused status to its response. Three migrations add the required columns and tables, with down-migration guards for recorded data.

Possibly related issues

• Gate automatic guest updates on immutable releases and rollout qualification #1726 — This change adds storage and reporting for runtime-upgrade outcomes and refusals, but does not implement the issue’s qualification matrix or release process.

Possibly related PRs

• perplexityai/SPACE#1380 — This change extends the outcome table and runtime-upgrade report contract introduced there with attempt IDs and per-attempt outcomes.
• perplexityai/SPACE#1756 — Both changes modify runtime-upgrade outcome writes, migrations, migration tests, and sandbox deletion handling.
• perplexityai/SPACE#1707 — Both changes define retention behavior for refusal records when a sandbox is deleted; this change uses cascading deletion for its new attempt-history tables.

Merge Risk: Moderate · previous review cc4a6

A runtime-upgrade retry that reuses an attempt ID after a rollback can fence and boot the sandbox again, even though the new schema comments say recorded attempts are final. Enforcement is planned for a follow-up PR, but the store or the migration comments should be aligned before merge, or the gap explicitly accepted.

Security architecture risk: Low · up to cc4a6

The change adds durable upgrade-attempt history while preserving existing caller permissions and sandbox identity checks. No introduced exploitable security defect was established. Downgrades deliberately become restricted once protected history exists, and operational rollback compatibility remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — History rows are sandbox-scoped, but downgrade guards count the entire relevant table. One protected row is therefore sufficient to block that database's corresponding schema downgrade, not merely a single sandbox's transition.

Trust Boundaries and Controls

• observed — UpgradeRuntime authorizes the peer before parsing the new field. Its unchanged allowlist includes root, the local operator role, and the node API service; staging requires additional start-context authority. GetRuntimeUpgrade uses the same upgrade authority and rejects a report naming another sandbox. Attempt IDs do not expand these permissions.

Resilience and Maintainability Implications

• observed — Rollback completion records the operation outcome, inserts attempt history, and deletes the rolled-back live row within one immediate transaction. Pre-fence refusal similarly commits operation and attempt records together. These transaction boundaries preserve recovery state rather than independently committing terminal history and live-row removal.

Hardening Proposals

• proposed — Validate that supported binary downgrades honor the guarded schema rollback path, or otherwise prevent older binaries from using databases containing history they cannot interpret. SQL guards alone should not be treated as proof of mixed-version rollback safety.

Full details: Title check

Explanation

The title uses the bracketed area prefix "[sbx-mgr]" as the title requirements allow, then a summary starting with the lowercase word "record". It states the main change: runtime upgrade outcomes and refused attempts are recorded per attempt ID in the store. The summary matches the changeset, which adds attempt-keyed outcome and refusal tables, writers, and readers. No trailing period, ticket ID, or internal link appears. Code identifiers keep their case.

Full details: Description Follows The Pr Template

Explanation

The PR description (perplexityai/SPACE #1754) has all four required items, each with real content. Checked against the contributor's prose as supplied, not a rewritten summary. 1. ## Summary: Present. It states the change: three sandbox-manager migrations and store functions that record and read each attempt's outcome, keyed by (operation_id, attempt_id). 2. ## Validation: Present. It lists the store and sandbox-manager tests run, the migration tests, the mutation checks, and the ci/scripts/run-rust-checks.sh results (clippy, doctests, nextest pass counts, and the seven failures attributed to the build box). It also states that a Kind smoke test was not validated. 3. ## Severity and risk: Present. It gives "Severity: does not apply on its own" and "Risk: low", with the reasons. 4. AI assistance: line: Present. It reads "AI assistance: Claude Code drafted the code, tests and this description.", which names the tool and the parts it drafted. No required item is missing or limited to template HTML comments. Presence is the only criterion here, so content quality was not judged.

Full details: Bug Fixes Name A Regression Test

Explanation

The check applies only when the PR fixes a defect in application behavior under crates/, shim/, or ui/. This PR does not fix a defect. The PR description calls it "the store half of per-attempt runtime upgrade finality." It adds three migrations, store writers and readers, and attempt ID generation. Its "Problem" section describes a missing capability: the store kept only the latest outcome per operation, with no attempt record. It does not describe a failing behavior that this change corrects. The PR also states "Severity: does not apply on its own; it's the storage the next pull request needs." The title and the objectives say the same. Because the PR is a feature and storage addition, the check does not apply. The PR's Validation section also names targeted tests, but those tests were not needed for this verdict.

Full details: Weakened Safeguards Are Justified

Explanation

The diff does not remove, disable, or weaken a test, assertion, lint, CI check, or repository guard. - Removed assertions: Four assert! lines were removed from crates/l30_storage/sbx/mgr/store/src/db/runtime_upgrades/tests.rs (old lines 903, 1229, 1245, 1261). Each is rewritten in the same hunk as an equivalent assertion with the same expected boolean. The only change is an added attempt_id argument (new_runtime_upgrade_attempt_id()) to record_runtime_upgrade_already_on_target. No expectation was loosened. - Migration test: crates/l30_storage/db/migrate/src/tests.rs has no removed lines. suspend_attempt_rollback_preserves_ownership_and_migration_history now rolls back newer migrations first, then runs the same assertions. The test count rose from 7 to 9 and assertions rose from 40 to 53. - Added suppressions: No #[allow], #[expect], skip, xfail, or continue-on-error was added. No allowlist, baseline, nextest exclusion, or SPACE_TEST_DEPS_OPTIONAL change appears. - Removed guards: The only removed production-code lines are functional SQL and signature edits that add attempt_id. None removes a WHERE or CHECK guard. The new down migrations add guards (CHECK (count = 0)), which strengthens them. - Protected files: No file under CI, AGENTS.md, CLAUDE.md, .agents/, CONTRIBUTING.md, or docs/rust/ changed. The changed non-Rust files are only the new .sql migrations and crates/l30_storage/sbx/mgr/store/Cargo.toml. The Cargo.toml change adds two feature names and removes nothing. - Review-steering text: Added comments describe retry and refusal semantics. None is written as review guidance or merge-risk rating text.

Full details: Agent Tooling Runs No New Commands

Explanation

The check covers agent plugin manifests (plugin.json, plugin.yaml), SKILL.md files, skill and command files, and guideline files. The changed-file inventory for PR #1754 (refs/coderabbit/pre-merge-check/base..head) has 18 entries. They are Rust sources and Cargo.toml under crates/, plus six sandbox-manager SQL migrations under db/sandbox-manager/. None of them is an agent plugin manifest, skill, command, or guideline file. A path filter for plugin, skill, command, hook, MCP, LSP, AGENTS.md, CLAUDE.md, and .md names matched nothing. A search of added diff lines for inline shell substitution (!`), hooks, allowed-tools, MCP/LSP server entries, and command keys found nothing. The PR adds no agent-run entries. The check is inapplicable, so it passes.

Full details: Public-Safe Content

Explanation

The public-safety scan found no failing content in the PR diff, title, or description. - Credentials and keys: No private-key blocks, access-key patterns, bearer tokens, or secret-like literals in added lines. Matches for "token", "secret", and "password" were absent. - Hostnames, URLs, and links: No scheme:// URLs, internal domains (.internal, .corp, .svc, .cluster, .k8s), or tracker/chat/document links in added lines. The PR description contains no URLs. It cites only PR numbers (#1753, #1755) and repo-relative paths (db/README.md, AGENTS.md, ci/scripts/run-rust-checks.sh). - Cloud IDs and ARNs: No 12-digit account numbers, arn: strings, or cloud-provider endpoints. - Personal absolute paths: No /Users/ or /home/ paths in added lines. - Emails and IPs: No email addresses or IP addresses in added lines. The commit author's email is not part of the diff, title, or description. - Production data and incidents: The description reports test counts (for example, 12853/12854 unprivileged). These are CI test results, not production logs or measurements. It has no incident details. - Security: The change adds storage for refused and rolled-back upgrade attempts. The description does not describe an unfixed vulnerability. - Fixtures: Test values such as attempt-a are obviously fake. The only uncertainty is that I scanned added lines with pattern matching and did not read every hunk. No failing content surfaced in any of the scans.

Persist the pod named by UpgradeRuntime.

If request.start.route_identity names a pod, this call still stores pod_uid: None. The already-on-target call at Line 603 also passes None. A later rollback therefore creates no per-pod outcome, and neither stored result can identify the requesting pod. Pass the request’s pod UID to both writers and cover a pod-bearing RPC request.

Include pod identity in the runtime-upgrade response.

If the store reports Refused for pod A, this branch returns the failure without report.pod_uid. The response also omits report.refused_pod when an upgraded or already-on-target operation refused a pod’s create. A caller cannot match either failure to the pod it is waiting for. Copy pod_uid, refused_pod_uid, and refused_pod_failure from the report, and test a response backed by a named-pod record. The PR description acknowledges that the pod-field mapping is deferred to #1755. (raw.githubusercontent.com)

Do not fence a pod with a final outcome.

If (operation_id, pod_uid) already has a rollback or refusal, begin_runtime_upgrade still inserts a new fence for that pod. The new each_pods_rollback_or_refusal_is_kept_for_that_pod test demonstrates a second rollback for pod-a; retaining its first history row does not prevent the second upgrade attempt. Check the per-pod final outcome before inserting the fence, and return it without booting. Ensure the service performs that check before staging work. (raw.githubusercontent.com)

Thanks. All three additional comments describe the next split, PR #1755, which this one is the storage for. No change here:

• Persist the pod named by UpgradeRuntime (runtime_upgrade.rs): this pull request adds the columns and writers but passes no pod yet, as its Summary says. PR [sbx-mgr] make a runtime upgrade rollback or refusal final for its attempt #1755 passes request.pod_uid() to begin_runtime_upgrade and record_runtime_upgrade_already_on_target.
• Include pod identity in the GetRuntimeUpgrade response (rpc.rs): listed under Not covered. PR [sbx-mgr] make a runtime upgrade rollback or refusal final for its attempt #1755 copies pod_uid, refused_pod_uid and refused_pod_failure from the report.
• Do not fence a pod with a final outcome (runtime_upgrades.rs): PR [sbx-mgr] make a runtime upgrade rollback or refusal final for its attempt #1755 enforces per-pod finality in the service. refuse_settled_for_pod answers a pod with its own recorded rollback or refusal before anything stages or fences, under the sandbox's upgrade guard. The store test's second rollback for pod-a drives the store directly to show the pod's history keeps its first outcome.

[zibi-pplx]

Following my comment on #1753, could we carry an opaque attempt_id through the storage layer too, including the columns, tables, and store APIs?

Sandbox-manager needs to retain outcomes by (operation_id, attempt_id), with the same ID across retries and a new ID for a replacement attempt. The Kubernetes substrate can derive that ID from the pod UID and own the mapping in the cluster/shim. Keeping the stored contract about attempts would let sbxmgr enforce finality without knowing about pods or their lifecycle.
