fix(wake): bound wake requests and preserve HostPort handoffs - #840
Wake requests could exceed the join budget, hide a shared request’s failure from concurrent callers and stall UDP receives. HostPort sleep/wake could also start a replacement listener before the previous Pod released its port or move it away from the advertised node.
Bound the shared wake PATCH and total join attempt, propagate the actual shared result, and coalesce UDP wake work behind a bounded queue. Persist the HostPort endpoint node and UID, wait for actual Pod drain in both directions, and pin game and sentinel workloads through scheduler affinity.
Planning and mutation both check live endpoint identity. A temporarily NotReady node can retain its existing running listener; missing or replaced identities prevent a listener from starting. Eligible running games receive a bounded graceful stop when the original endpoint node is deleting, behind a durable fence that prevents replacement Pods from starting there. While that original Pod is fenced, active backup/recovery ownership takes precedence over save/stop RPCs.
The controller retires its temporary stop fence after endpoint recovery while preserving unrelated scheduling gates and valid saved update strategies. The stop path also synchronizes lifecycle ownership so admitted template rollouts can observe completed drainage without bypassing endpoint fencing. Before normal StatefulSet rendering, concurrent changes to the planned exposure mode, endpoint node or UID cause a retry; identity-loss stop and graceful-stop handling retain priority.
Implements the maintainer-approved scope of #729: a PATCH timeout within the join budget, a bounded, coalescing UDP wake worker, and shared failure reporting. The broader #729 remains open for application-level transient retry with jitter/backoff and a combined slow-cold-start TCP/UDP load scenario. Closes#730.
Supersedes #761. Prior review discussion remains on that PR.
This PR targets master.
Validation: Linux operator/sentinel builds and operator envtest, sentinel and E2E regression-source compilation passed. Coverage includes shared wake budgets, shared-call concurrency and separate TCP/UDP regressions and a two-node CI bucket for repeated HostPort handoffs, occupied ports, terminating sentinels, cordoned nodes and node deletion. Runtime tests and cluster checks run in CI under the repository’s compile-only local policy.
Current validation: all 110 main CI jobs passed on 4693c9ed (CI run); four external download/setup failures passed on a targeted retry. Visual regression and portable-path checks also passed. Operator unit tests, envtest and E2E passed on both architectures, including the endpoint-input regressions; the dedicated wake-hostport, recovery and backup-preparation suites passed. The report regression verifies that skipped or missing HostPort test steps are not counted as executed. Independent code review completed. CodeRabbit automatic reviews resumed, and its latest review accepted the follow-up fix with no further actionable findings. All review threads are resolved.
Summary by CodeRabbit
New Features
Hostport wake handoffs keep game servers pinned to their recorded endpoint node and coordinate game and sentinel shutdowns before waking or restarting workloads.
Added Hostport status messages for endpoint availability, scheduling, and listener readiness.
Wake requests are coalesced and time-bounded, while established gameplay sessions can continue beyond the wake deadline.
Bug Fixes
Improved handling of unavailable, changing, or deleting endpoint nodes to prevent unintended workload movement or premature restarts.
Documentation
Documented Hostport handoff behavior, status messages, and end-to-end test coverage.
The operator now records and validates Hostport endpoint identity, coordinates game and sentinel placement during sleep and wake, and reports handoff readiness. Sentinel wake requests use bounded, shared processing. A two-node end-to-end bucket tests the handoff and is integrated into CI.

The operator reads and validates the recorded endpoint Node, plans Hostport listener handoffs, pins workloads to the endpoint, and reports Hostport conditions. Tests and specifications cover endpoint identity, readiness, and placement.
Graceful stop fencing on deleting Nodes operator/internal/controller/gameserver_hostport_stop.go, operator/internal/controller/gameserver_hostport_stop_test.go, operator/internal/controller/gameserver_hostport_lifecycle_test.go, operator/internal/controller/gameserver_hostport_inputs_test.go
The controller fences replacement scheduling before stopping the original game Pod on a deleting endpoint Node. Tests cover identity checks, lifecycle ownership, fence validation, and cleanup.
Sentinel placement and reverse handoff operator/internal/controller/gameserver_sentinel.go, operator/internal/controller/gameserver_sentinel_envtest_test.go, operator/internal/controller/gameserver_hostport_identity_test.go
Sentinel reconciliation validates the endpoint and GameServer, applies Hostport scheduling constraints, and coordinates drain and deletion. Tests cover stale plans, readiness, and handoff ordering.
Bounded sentinel wake requests sentinel/main.go, sentinel/udp_wake.go, sentinel/wake_budget_test.go, sentinel/specs.md, operator/specs.md
Wake PATCH attempts share in-flight results and use a timeout. The join deadline covers the wake request and upstream polling. UDP wake requests use a one-slot worker, with tests for cancellation, coalescing, and session lifetime.
Two-node acceptance test and CI selection test/e2e/hostport_wake_e2e_test.go, test/e2e/buckets.sh, test/e2e/ci_selection_e2e_test.go, test/e2e/specs.md, test/e2e/suite-components.json, .github/workflows/ci.yaml, deploy/kind/e2e.sh, hack/ci_scope.py, hack/test_ci_scope.py, hack/test-check-ci-report-coverage.sh
The new e2e bucket checks Hostport handoff across two nodes and endpoint loss. CI uses the two-node profile, selects and reports the bucket, and maps it to the affected components.
GameplanePanel/Gameplane#761: PR #840 supersedes it and extends the Hostport handoff and sentinel wake changes with cancellation retries, UDP worker coalescing, and graceful-stop fencing.
The previously identified risk of pinning a workload to a stale Hostport endpoint is addressed. No actionable merge-blocking issue remains after normal checks.

Explanation
The title "fix(wake): bound wake requests and preserve HostPort handoffs" matches the main changes. The sentinel wake path now bounds PATCH and join budgets, shares in-flight PATCH results, and queues UDP wake work. The operator now persists HostPort endpoint node identity and drains pods across sleep/wake handoffs. The title is concise, specific, and follows the conventional-commit style. It does not cover the stop fence or RBAC changes, which is acceptable for a summary.
Full details: Linked Issues check
Explanation
[#730] Only #730 is a directly linked issue. #729 appears only in the PR description and objectives, so its requirements are not assessed here.
Whole-PR evidence, merge base 4f5f5aa to head 4693c9e, from the summary and focused checks:
Stable endpoint through repeated sleep/wake: the controller records the endpoint node name and UID (gameserver_hostport.go, gameserver_sentinel.go). Hostport affinity pins the game and the sentinel to the recorded node. test/e2e/hostport_wake_e2e_test.go (TestGameServer_HostportWakeStableEndpoint) runs two sleep/wake cycles on a two-node cluster.
Listener handoff while the old port is occupied, with no false Ready: the e2e test checks reachability while the terminating Pod still holds the port, and checks that the waker is not created until the port is released. Sleep waits for game drain before the sentinel is requested. Wake waits for sentinel removal before the listener is marked ready (ListenerPending, GameDraining, SentinelDraining). The envtest sentinel test checks that the sentinel does not overlap a live game Pod.
Dedicated game-node taints: sentinel Pods inherit the GameServer scheduling constraints and affinity. The e2e test dedicates a worker endpoint. The summary does not state explicitly that tolerations are copied. This is a residual uncertainty.
Node failure: a missing, deleting, or replaced recorded node scales the game to zero and sets EndpointNodeUnavailable. The e2e test checks that deleting the endpoint node yields this condition without moving Pods. The PR uses the explicit unavailable-condition option that the issue allows.
Service-backed exposure and session draining: the summary states that Service-backed modes keep the readiness-based sentinel path. handleJoin cancels the wake deadline after upstream connect, so proxying continues under the session context.
Residual uncertainties: (a) The e2e, envtest, and CI results are reported for commit c51bd33 in the PR description. They were not independently run at head 4693c9e. (b) The .github diff could not be read because changed blobs are missing from the checkout. The ci.yaml bucket changes rely on the AI-generated summary. Source evidence for the controller and sentinel logic supports compliance.
Full details: Out of Scope Changes check
Explanation
Changes that serve #730 are connected to its requirements. These include the Hostport controller and sentinel logic, node-identity checks, the stop fence for a deleting endpoint node, RBAC get on nodes (operator/config/rbac/role.yaml, chart operator.yaml), the wake-hostport e2e bucket and CI selection (ci.yaml, hack/ci_scope.py, test/e2e/*), condition messages (i18n/locales/en/app.json, hack/condition-ids/main.go), and the Hostport handoff specifications (operator/specs.md, test/e2e/specs.md).
Sentinel wake changes (sentinel/main.go, sentinel/udp_wake.go, sentinel/wake_budget_test.go, wake sections of sentinel/specs.md) do not map to a #730 requirement. The PR description declares them as the scope of #729, which the PR cites as a maintainer-approved comment. #729 is not a linked issue, and that comment was not readable from the available tools. The changes are therefore declared scope, not demonstrated unrelated work. Maintainers should confirm that this wake scope belongs in this PR.
The objectives cite CI security dependency updates (GO-2026-6865, GO-2026-6860) and a shared Trivy installer change. The diffs of sentinel/go.mod and operator/go.mod against the merge base are empty. The .github diff could not be read because changed blobs are missing from the checkout. The whole-PR summary lists no Trivy or dependency change in .github. These objective claims therefore cannot be confirmed or excluded. They are not described in the PR description, so no demonstrated out-of-scope change is established.
House-rule documents (CLAUDE.md, Constitution) were not read in this assessment. No house-rule violation is assessed.

The inspected workflow supports no unsafe entry path or action-pinning violation. The repository comment describes the environment policy, but does not establish the live settings.
The production reconciler sets APIReader, so the claimed fallback to the cache-backed client does not occur on that path.
99-123: Functional Correctness
The reported block is consistent with the endpoint identity policy. The annotations can be cleared through the documented migration procedure; the state is not permanent. Skipping the record could remove the identity fence without proving that the later node is the original endpoint.
The status combination is possible, but the inspected consumers do not establish the claimed incorrect report or blocked action. Preserving a running Pod also does not establish that its endpoint is reachable.
Apply reviewed canonical checksum normalization 0cc80c1 after the x/net image security update. Keep the isolated frpc module and all dependency selections unchanged.

Source excerpt: **Operator authority:** business logic lives in reconcilers (`operator/internal/controller/`); the API is a UX gateway and never bypasses reconciliation.
The inspected code does not establish a path that produces invalid fence metadata without an external change. The fallback is documented, and no requirement establishes that it must emit a log or event.
The proposed mismatch is not supported by the inspected reconciliation path. The GameServer is refreshed before planning, and endpoint recording updates the snapshot passed to reconcileStatefulSet.
Clarified #729's scope in the PR description and removed its automatic closing reference. The maintainer's three requested fixes are implemented: a PATCH timeout inside the join budget, a bounded/coalescing UDP worker, and shared actual failure results. Application-level transient retry with jitter/backoff and combined slow-cold-start TCP/UDP load evidence remain follow-up work in #729.
Existing tests cover delayed upstream availability, deadline responses, shared failure/cancellation, and a 101-datagram UDP burst. That is component evidence; it does not establish mixed-protocol load capacity or a real game's cold-start capacity.
The security dependency updates address GO-2026-6865 and GO-2026-6860 found by CI. The shared Trivy installer retains checksum verification, bounded retries, and the existing vulnerability failure gates. Those prerequisites are retained so the feature branches can pass the required checks.

# Gameplane Constitution
## Core Principles
### I. E2E-Tested Delivery (NON-NEGOTIABLE)
Every feature MUST be verifiable end-to-end before it is considered done. A change is
incomplete — regardless of unit or integration coverage — until it has a corresponding
E2E test exercising the real user- or operator-facing path (dashboard flow, API contract,
CRD reconciliation loop, or agent behavior) in `test/e2e/`, added to a bucket in
`test/e2e/buckets.sh` per the project's e2e conventions. Unit tests (`make test-go`,
`make test-web`) and envtest integration tests (`make test-integration`) are required
supporting layers, not substitutes. New E2E tests MUST call `t.Parallel()`, use
per-test unique resource names, and respect existing shared-state guards
(`ociPushMu`, `ensureResticRepo`, per-bucket login budgets).
339-348: Sentinel shares the game's NodeSelector and Tolerations by reference.
gs.Spec.NodeSelector and gs.Spec.Tolerations are assigned directly to the Deployment template. The mutate function runs on the reconciler's own gs copy, so aliasing is low risk. The game StatefulSet code uses the same pattern. No action is needed unless the template is mutated later. This note records the shared pattern only.

## Core Principles
### IV. Spec-Driven Development
Every module folder (each Go module directory such as `netguard/`, `gameaction/`,
`gameproto/`, `operator/`, `api/`, `agent/`, `audit-syslog-bridge/`,
`telemetry-receiver/`, `sentinel/`, `mcp-server/`; the `web/` tree; and each game
directory under `modules/<name>/`) MUST maintain a `specs.md` describing in detail how
that module actually works: its responsibilities and boundaries, the protocols or
contracts it implements (e.g. the wire-protocol handshake a `modules/<game>/` directory
speaks, or the CRDs a controller reconciles), its inputs/outputs, and the invariants
other modules depend on. `specs.md` MUST be updated in the same change that alters the
behavior it documents — a behavior change without a matching `specs.md` update is
incomplete.

Wake requests could exceed the join budget, hide a shared request’s failure from concurrent callers and stall UDP receives. HostPort sleep/wake could also start a replacement listener before the previous Pod released its port or move it away from the advertised node.
Bound the shared wake PATCH and total join attempt, propagate the actual shared result, and coalesce UDP wake work behind a bounded queue. Persist the HostPort endpoint node and UID, wait for actual Pod drain in both directions, and pin game and sentinel workloads through scheduler affinity.
Planning and mutation both check live endpoint identity. A temporarily NotReady node can retain its existing running listener; missing or replaced identities prevent a listener from starting. Eligible running games receive a bounded graceful stop when the original endpoint node is deleting, behind a durable fence that prevents replacement Pods from starting there. While that original Pod is fenced, active backup/recovery ownership takes precedence over save/stop RPCs.
The controller retires its temporary stop fence after endpoint recovery while preserving unrelated scheduling gates and valid saved update strategies. The stop path also synchronizes lifecycle ownership so admitted template rollouts can observe completed drainage without bypassing endpoint fencing. Before normal StatefulSet rendering, concurrent changes to the planned exposure mode, endpoint node or UID cause a retry; identity-loss stop and graceful-stop handling retain priority.
Implements the maintainer-approved scope of #729: a PATCH timeout within the join budget, a bounded, coalescing UDP wake worker, and shared failure reporting. The broader #729 remains open for application-level transient retry with jitter/backoff and a combined slow-cold-start TCP/UDP load scenario. Closes #730.
Supersedes #761. Prior review discussion remains on that PR.
This PR targets master.
Validation: Linux operator/sentinel builds and operator envtest, sentinel and E2E regression-source compilation passed. Coverage includes shared wake budgets, shared-call concurrency and separate TCP/UDP regressions and a two-node CI bucket for repeated HostPort handoffs, occupied ports, terminating sentinels, cordoned nodes and node deletion. Runtime tests and cluster checks run in CI under the repository’s compile-only local policy.
Current validation: all 110 main CI jobs passed on
4693c9ed(CI run); four external download/setup failures passed on a targeted retry. Visual regression and portable-path checks also passed. Operator unit tests, envtest and E2E passed on both architectures, including the endpoint-input regressions; the dedicated wake-hostport, recovery and backup-preparation suites passed. The report regression verifies that skipped or missing HostPort test steps are not counted as executed. Independent code review completed. CodeRabbit automatic reviews resumed, and its latest review accepted the follow-up fix with no further actionable findings. All review threads are resolved.Summary by CodeRabbit
