[sbx-mgr] add the per-attempt runtime upgrade fields and AbandonRuntimeUpgrade to the wire - #1753
The wire change alone for the per-attempt runtime upgrade work, with the regenerated shim Go. Nothing sets the new fields yet, and sandbox-manager answers the new RPC UNIMPLEMENTED, so merging changes no behavior.
Terms
Attempt: one try at an UpgradeRuntime operation, named by an opaque attempt_id the caller picks. Sandbox-manager records and reports outcomes per (operation_id, attempt_id) and knows nothing of what made the attempt: a Kubernetes substrate derives the ID from the pod UID, and a CLI or SDK generates one. A request that names no ID starts a fresh attempt, whose ID the node generates and returns.
Final for an attempt: a recorded outcome that every retry under the same attempt ID gets back unchanged, without fencing or booting again. Only a new attempt tries again.
Abandon: the control plane giving up one UpgradeRuntime operation on a node, so no later call for it fences or boots, under any attempt ID.
The problem
The pull requests after this one record and report runtime upgrade outcomes per attempt, and add AbandonRuntimeUpgrade. Their wire fields and the regenerated shim/proto/sandbox/manager/v1/manager.pb.go come to about 1,900 lines on their own, almost all generated. Carrying them inside the pull requests that change behavior would bury that behavior under generated code. They're here instead, so those pull requests stay reviewable.
How this fixes it
UpgradeRuntimeRequest gains an optional attempt_id (9), and UpgradeRuntimeResponse returns it (3). The same ID continues an attempt or replays its final outcome, and reusing it with a different sandbox, target or authorization is refused with INVALID_ARGUMENT. A new ID tries again while the operation hasn't started the sandbox; once its boot or an activation ran an execution, a later call gets it only by target_state's route-identity rule, and trying again takes a new operation_id. An omitted ID starts a fresh attempt, and the node generates, records and returns its ID.
GetRuntimeUpgradeResponse gains the per-attempt fields.attempt_id is the attempt the reported outcome ran for. refused_attempt_id and refused_attempt_failure name the latest attempt whose activation an upgraded or already-on-target operation refused. abandoned says the control plane abandoned the operation on this node. All are new field numbers (5 to 8); an older reader ignores them.
GetRuntimeUpgradeRequest gains an optional attempt_id (3), the attempt a caller waits on. When it's set, the node answers with that attempt's own rollback or refusal, and ABSENT in place of another attempt's, so a later attempt never changes what this one is told. An older node ignores the field and answers the latest outcome.
RuntimeUpgradeStatus gains REFUSED (6), for an attempt refused before it fenced anything for a reason no retry changes.
SandboxManager gains AbandonRuntimeUpgrade, documented with the answers a caller must handle: which unsettled operations it settles first, which ones answer ABORTED, INVALID_ARGUMENT or UNAVAILABLE, and that only OK proves the operation abandoned, so a caller retries on any error rather than capture the disk. Abandonment covers the whole operation, not one attempt. The sandbox-manager adapter answers it UNIMPLEMENTED until the pull request that implements it, and restart admission classifies it as a state writer, so a draining sandbox-manager refuses it with its usual retry-on-successor answer.
The UpgradeRuntime, GetRuntimeUpgrade and ABSENT comments describe the per-attempt contract the following pull requests implement.
The regenerated manager.pb.go and manager_grpc.pb.go.
Validation
The shim's Go regenerates byte-for-byte from manager.proto with the pinned protoc 35.0, protoc-gen-go v1.36.11 and protoc-gen-go-grpc 1.6.1, and go build ./... builds the shim.
cargo clippy --workspace --all-targets --locked -D warnings is clean.
The full workspace run through CI's entry points (run-rust-checks.sh tests-unprivileged, then tests-privileged under with-nocow-test-filesystem.sh) on a Linux build box:
Unprivileged: 12,797 of 12,798 passed. The one failure, node-mgrexecution_fence::tests::stopped_unbound_snapshot_reaches_filesystem_without_allocating, is intermittent on this build box: it passed there on an earlier head, it passes in CI, and this change doesn't touch node-mgr.
Privileged: 72 of 78 passed. The six failures need host features the build box lacks: fs-verity (three node-runtime-core tests), root-owned ancestors of the temporary directory (two contained_launcher tests) and a private cgroup namespace (spaced-guest-workerembedding). CI's privileged lane runs them.
every_served_rpc_has_explicit_restart_admission checks that restart admission's RPC table covers every rpc in manager.proto. With the new AbandonRuntimeUpgrade entry removed, it fails; with it, it passes.
Not validated: a Kind smoke on this change alone. It ran on the eight changes together.
No actionable comments were generated in the recent review.
Walkthrough
The API adds attempt-scoped runtime-upgrade outcomes, including attempt identifiers, refusal details, and the REFUSED status. It documents retry and replay rules for upgrade attempts and adds the AbandonRuntimeUpgrade RPC contract. The server classifies the RPC as a state writer. Its handler records the sandbox ID on the tracing span and returns UNIMPLEMENTED.
Merge Risk: Minimal · up to 0cb45
This PR adds attempt-aware runtime-upgrade fields and an abandon RPC to the wire contract without changing runtime behavior. The new RPC returns UNIMPLEMENTED, and no caller sets the new fields yet. The merge risk is minimal. The behavioral risk sits in the follow-up PRs that implement these semantics.
Security architecture risk: Minimal · up to 0cb45
The new contract warrants review, but the inspected changes do not enable new sandbox operations or weaken existing controls. Abandonment explicitly fails as unsupported, attempt support is not advertised, and the contract requires callers to recognize those limitations before relying on the new guarantees.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The added abandonment handler accepts caller-supplied sandbox and operation identifiers, records the sandbox identifier in the current tracing span, and returns a fixed UNIMPLEMENTED error. Its complete body contains no database mutation, fencing, activation, boot, or disk-capture call, so it does not grant abandonment authority in this revision.
Trust Boundaries and Controls
observed — Existing UpgradeRuntime and GetRuntimeUpgrade handlers retain peer authorization through ALLOW_SANDBOX_RUNTIME_UPGRADE. Staging additionally requires start-context authority, execution remains under the sandbox upgrade lock, and reporting rejects an operation recorded for another sandbox. The new stub has no corresponding authorization call, but also performs no sandbox action; restart classification is not an authorization control.
Resilience and Maintainability Implications
observed — The new RPC path is explicitly classified as StateWriter. The existing admission layer therefore acquires a writer guard before dispatch, rejects admission when that acquisition fails during drain, and retains admitted work under tracked task ownership. The route does not bypass restart-drain handling.

Explanation
The title names the sbx-mgr area and the main change: per-attempt runtime upgrade fields and the AbandonRuntimeUpgrade RPC added to the wire. The changeset adds these proto fields, the REFUSED enum value, and the RPC, with a stub adapter and restart-admission entry. The title does not match the required format. It uses a bracketed area, which is allowed, but the summary should start with a lowercase word. 'add' is lowercase, so the casing rule is met. Code identifiers keep their case, so 'AbandonRuntimeUpgrade' is valid. The title has no trailing period and no ticket ID. The title meets the format rules and describes the change accurately.

The PR description (PR #1753, the-gigi-pplx) contains all four required items with real content: 1. ## Summary: Present. It states that merging adds the wire change only (per-attempt fields, REFUSED, and AbandonRuntimeUpgrade) and that merging changes no behavior. 2. ## Validation: Present.

All four items are present, so there is no failing item to name. No repository inspection was needed because the check applies only to the description text.
Full details: Bug Fixes Name A Regression Test
Explanation
The check applies only when the pull request fixes a defect in application behavior under crates/, shim/, or ui/. This pull request is not a bug fix. The contributor describes it as a wire-only change. It adds optional attempt_id fields, adds the REFUSED enum value, and adds the AbandonRuntimeUpgrade RPC to manager.proto. It also regenerates the shim Go files and adds a restart-admission entry. The contributor states that "merging changes no behavior." The sandbox-manager adapter answers the new RPC with UNIMPLEMENTED, and no caller sets or reads the new fields. The raw summary lists the Rust changes as a new stub, a classification entry, and test fixtures that set attempt_id: None. None of these fixes a reported defect. Under the check text, this pull request passes. I did not run repository tools, because the pull request description and summary establish the change type.
Full details: Weakened Safeguards Are Justified
Explanation
The diff (base to head, 9 files) does not remove, disable, narrow, or weaken any test, assertion, lint, CI check, allowlist, or repository guard. - Rust changes are additive. Every hunk under crates/ is a + line. The additions are attempt_id: None fields in test fixtures and helpers (worker/tests.rs, runtime_upgrade/rpc/tests.rs, runtime_upgrade/tests.rs, runtime_upgrade/rpc.rs). They also add a new abandon_runtime_upgrade adapter method that returns Status::unimplemented, and one SandboxAbandonRuntimeUpgrade => (..., StateWriter) entry in restart_admission.rs. That entry adds coverage for the new RPC. The restart-admission test itself is unchanged. - No #[allow], #[expect], skip, xfail, or continue-on-error additions. A grep of added lines found none. - No test deletions or assertion removals. No Rust test or assertion line is removed. - No CI, lint, allowlist, nextest, or baseline edits.name-status lists no files of these kinds. - No edits to AGENTS.md, CLAUDE.md, CONTRIBUTING.md, .agents/, or docs/rust/. No review-guidance text changed. - The only removed lines are prose comments in proto/sandbox/manager/v1/manager.proto. These rewrite the UpgradeRuntime, GetRuntimeUpgrade, and ABSENT API documentation to describe the per-attempt contract. They are not tests, lints, CI checks, or guards in the check's list. - Generated Go files (manager.pb.go, manager_grpc.pb.go) change only as regenerated output of the proto. No failure condition in the custom check applies.
Full details: Agent Tooling Runs No New Commands
Explanation
This check covers agent plugin manifests (plugin.json, plugin.yaml), skills (SKILL.md), command files, and guideline files. The PR does not change any of them. The changed-file inventory has 9 files: Rust sources under crates/l40_api (adapter.rs, restart_admission.rs, runtime_upgrade/rpc.rs, and three test files), proto/sandbox/manager/v1/manager.proto, and the regenerated shim Go files manager.pb.go and manager_grpc.pb.go. A path filter for plugin manifests, SKILL.md, skills/commands directories, .claude/, CLAUDE.md, AGENTS.md, guideline files, hooks, MCP, LSP, and .md files returned no matches. No agent-tool content is added, so no hook, MCP/LSP server, frontmatter key, or inline shell substitution can be introduced. The check does not apply.
Full details: Public-Safe Content
Explanation
The public-safe content check passes. I scanned all added lines in the 9 changed files (about 1,527 lines, including the regenerated shim Go and the manager.proto comments) for personal absolute paths (/Users/, /home/), URLs and http(s):// links, internal hostnames (.internal, .corp, .local), AWS ARNs and 12-digit account IDs, private key blocks, AKIA and ghp_ style tokens, password/secret/token assignments, IPv4 addresses, and references to trackers or chats (Slack, Jira, Confluence). None matched. The PR title and description contain no URLs, credentials, cluster or environment names, or incident or production data. They name only sibling PR numbers (#1752, #1754 to #1756), crate names, a pinned toolchain, and test counts. These are not sensitive. The proto comments describe the attempt and abandon contracts in general terms, and they contain no vulnerability details.

Could we keep pod terminology out of sandbox-manager's upgrade contract and use an opaque attempt_id instead (attempt_id, refused_attempt_id, and refused_attempt_failure in these messages)?
The ID should stay stable across retries and change for each replacement attempt. The Kubernetes substrate can derive it from the pod UID, with the cluster/shim owning that mapping. Sandbox-manager would only record and report outcomes by (operation_id, attempt_id), without needing to understand pods or their lifecycle. Other substrates could supply their own IDs under the same contract; abandonment would remain scoped to the whole operation.
Building on my attempt-ID comment, could we define this contract for standalone nodes too? A local caller should be able to use sbxmgr without manually managing attempt IDs or needing a cluster.
For upgrades, could attempt_id be optional, with explicit semantics?
Omitted: start a fresh attempt; sbxmgr generates, persists, and returns its ID.
Same ID: continue/query the existing attempt or replay its terminal outcome, without executing it again. Reusing the ID with different request parameters is rejected.
New ID: intentionally try again, subject to the normal lifecycle and concurrency checks.
operation_id would still identify the logical upgrade; attempt_id distinguishes attempts within it. This is useful even on one node, because RPC retries and lost responses happen without placement changes.
The caveat is losing the first response containing a node-generated ID: another anonymous request cannot reliably be recognized as the same attempt. I'd therefore have the CLI/SDK generate IDs automatically before sending and reuse them on transport retries, while allowing advanced callers to supply their own. That keeps the simple standalone interface and gives retrying clients a stable identity.
Kubernetes can derive its attempt ID from the pod UID at the cluster/shim boundary. Sbxmgr should only understand attempts and their outcomes, regardless of substrate.

[sbx-mgr] add the per-attempt runtime upgrade fields and AbandonRuntimeUpgrade to the wire
Nov 12, 2026
GetRuntimeUpgradeResponse reports attempt_id (5), refused_attempt_id (6) and refused_attempt_failure (7). These replace pod_uid, refused_pod_uid and refused_pod_failure, on the same field numbers, none of them merged yet.
GetRuntimeUpgradeRequest filters on attempt_id (3) instead of pod_uid.
Sandbox-manager records and reports outcomes per (operation_id, attempt_id). The ID is opaque to it. The UpgradeRuntime, ROLLED_BACK, REFUSED and ABSENT comments say "final for that attempt" and "a new attempt starts over", and finality no longer keys on start.route_identity.pod_uid.
Kubernetes appears only as an example: its substrate derives the ID from the pod UID at the cluster and shim boundary.
Abandonment stays scoped to the whole operation: under any attempt ID, no later call fences, boots or activates the sandbox in place.
Optional attempt_id on UpgradeRuntime, for standalone nodes (second comment)
UpgradeRuntimeRequest.attempt_id (9) is optional, with the semantics you proposed:
Omitted: a fresh attempt. The node generates its ID, records it and returns it in the new UpgradeRuntimeResponse.attempt_id (3). A retry that omits it again is another fresh attempt, so a caller that may retry supplies one.
Same ID: continues that attempt, or answers with its final outcome without running it again. Reusing it with different request parameters (defined below) is refused with INVALID_ARGUMENT.
New ID: tries again, subject to the usual lifecycle and concurrency checks. Once the operation's boot or an activation has run an execution, a later call gets that execution only through the existing route-identity rule in target_state; otherwise it's refused, and trying again takes a new operation_id. That keeps "one operation starts the sandbox at most once" intact.
Two more points the comments now pin down. "Different request parameters" means a different sandbox_id, target_environment, target_state or authorization; start's per-launch fields aren't compared. And a refused request carries no response, so it can't return a node-generated ID.
The field comment says a CLI or SDK should generate the ID before sending and reuse it on transport retries, which covers the lost-first-response caveat you raised.
What this PR does and doesn't do
This PR is still wire-only. Sandbox-manager doesn't generate, record or answer attempt IDs yet. The pull requests stacked on it do that and adapt to the new names: PR #1754, PR #1755 and PR #1756, and on top PR #1707. The Kubernetes shim's change to send its pod UID as attempt_id comes with them.
The change is in the force-pushed single commit, [sbx-mgr] add the per-attempt runtime upgrade fields and AbandonRuntimeUpgrade to the wire.
The reason will be displayed to describe this comment to others. Learn more.
[Should fix] The contract doesn't say which attempt_id values are valid. The two RPCs that take it will disagree. In #1756, UpgradeRuntime refuses an empty or whitespace-only id with INVALID_ARGUMENT and caps it at 256 bytes (parse_attempt_id, MAX_ATTEMPT_ID_BYTES). GetRuntimeUpgrade instead treats an empty id as unset and answers the latest outcome. The value is opaque, caller-chosen and persisted, and the Kubernetes shim and a CLI/SDK will each generate it, so the rules belong in the proto. Otherwise a Go caller that sets proto.String("") gets a refusal from one RPC and the operation's latest outcome from the other, and could settle on another attempt's answer. Fix: document the rules here and on GetRuntimeUpgradeRequest.attempt_id, and make the two RPCs agree (refuse an empty id in both, or treat it as omitted in both).
Suggested change
optional string attempt_id = 9;
// Set means non-empty and at most 256 bytes; an empty or longer id is
The reason will be displayed to describe this comment to others. Learn more.
[Should fix] With attempt_id set, the comment doesn't say which answer wins when the named attempt has its own rollback or refusal but the operation later moved on. Example: attempt A rolled back, then attempt B was UPGRADED. Under "IN_PROGRESS, UPGRADED and ALREADY_ON_TARGET describe the operation whichever attempt began them ... and are answered as they are unfiltered", a query for A could get UPGRADED. #1756 instead returns A's own ROLLED_BACK first (runtime_upgrade_attempt_outcome runs before the operation's report is read). A caller waiting on A needs this order to decide whether A is final, so state it explicitly. Fix: add one sentence, for example: "The named attempt's own rollback or refusal, when recorded, is answered first, whatever the operation reached since; otherwise the answer is as below."
The reason will be displayed to describe this comment to others. Learn more.
[Should fix] Three comments each list which refusals are recorded and final and which are left unrecorded: this UpgradeRuntime comment, RUNTIME_UPGRADE_STATUS_ABSENT (lines 1459-1466) and RUNTIME_UPGRADE_STATUS_REFUSED. Their wording already differs. For example, ABSENT adds "one whose refusal the node failed to write" and "before it could take the sandbox's upgrade lock", which this comment omits. Every refusal path #1755 adds or reclassifies then needs three matching edits, and a reader can't tell which list is the authoritative one. Fix: keep the list in one place (the REFUSED value is the natural home: recorded, final for the attempt, retried only by a new attempt). Have UpgradeRuntime and ABSENT point to it instead of repeating it.
The reason will be displayed to describe this comment to others. Learn more.
[Question] This contract makes abandonment a permanent record. It "outlives the sandbox's row" (ABSENT comment), and abandoning an operation the node "never saw records it abandoned and succeeds". So each abandon, including retries for operations that never reached this node, adds a tombstone that nothing removes (#1756's sandbox_runtime_upgrade_abandoned has no GC path). How long must a node keep it? If the answer is "as long as a late UpgradeRuntime for that operation can arrive", put that bound in the contract (for example, kept for N days after the abandon). Callers then know when the guarantee lapses, and #1756 can prune the table.
The reason will be displayed to describe this comment to others. Learn more.
[Consider] "as before" describes history rather than current behavior. Once the field exists, a reader has no "before" to compare against.
