133-137: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueRestore the module spies in the new describe block.
This describe block spies on
openshellRuntime.captureResolvedOpenshellandportableAgentLifecycle.recoverPortableAgentSandboxLifecycle. It has noafterEachrestore. The first describe block in this file restores its mocks at Lines 31-33.No current test fails, because the test at Line 180 re-establishes both spies. A test added after Line 222 would silently receive the leaked module spies instead of the real implementations.

853-862: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueAttribute the exec-ready currentness assertions to a currentness stage.
Inside the exec-ready loop,
assertLifecycleTransactionCurrentruns without ameasurewrapper. Its duration accumulates intoexecReadyMs. The equivalent assertions at Line 879 and Line 936 accumulate intohealthPollCurrentnessMs.The emitted evidence therefore attributes the same operation to different stages depending on the caller. This weakens the latency attribution that the timing evidence exists to provide. Consider wrapping these two calls in a currentness stage so
execReadyMsmeasures only the OpenShell exec probe.♻️ Proposed attribution fix
timing.increment("execReadyAttempt"); if (qualified.hasTransactionAuthority) { - assertLifecycleTransactionCurrent(qualified, timing, true); + timing.measure("preHealthCurrentness", () => + assertLifecycleTransactionCurrent(qualified, timing, true), + ); } const result = capture( openshellExecArgs(qualified.receipt, ["true"]), Math.min(COMMAND_TIMEOUT_MS, remainingMs), ); if (qualified.hasTransactionAuthority) { - assertLifecycleTransactionCurrent(qualified, timing, true); + timing.measure("preHealthCurrentness", () => + assertLifecycleTransactionCurrent(qualified, timing, true), + ); }🤖 Prompt for AI Agents

1917-1941: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winCollapse the duplicated recovery dispatch into one helper.
Lines 1917-1941 and Lines 2000-2016 repeat the same three-way dispatch over
recoverPortableDemoSandboxLifecycleForConnect. The arms differ only in the registry entry and gateway name. The middle arm passesundefinedpositionally forcommandAuthority.
recoverPortableDemoSandboxLifecycleForConnectnow takes five positional parameters. Positionalundefinedplaceholders in two duplicated blocks make a future argument insertion easy to get wrong silently. A single local helper removes both risks.♻️ Proposed helper
const recoverLifecycleForConnect = ( entry: SandboxEntry | null, gateway: string, ): PortableDemoLifecycleRecoveryResult => recoverPortableDemoSandboxLifecycleForConnect( sandboxName, entry, gateway, hermesPortableCommandAuthority, hermesPortable && probeTiming ? { onComplete: writeHermesPortableLifecycleRecoveryTiming } : undefined, );Then both sites reduce to
measure("lifecycle", () => recoverLifecycleForConnect(registered, gatewayName)). Confirm that passingundefinedforcommandAuthoritymatches the current behavior of the third arm before applying this.🤖 Prompt for AI Agents

198-198: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winUse distinct runtime authority spies.
assertRetainedCurrent,assertTransactionCurrent, andassertCurrentall use the sameassertRuntimemock. The harness cannot detect a regression that uses full authority revalidation instead of retained-currentness validation. The production contract distinguishes these checks.Create separate
vi.fncallbacks and assert the expected callback through the timing or failure outcome.Proposed test-harness fix
- const assertRuntime = vi.fn(() => events.push("runtime")); + const assertRetainedCurrent = vi.fn(() => events.push("runtime")); + const assertTransactionCurrent = vi.fn(() => events.push("runtime")); + const assertCurrent = vi.fn(() => events.push("runtime")); const createRuntimeAuthority = vi.fn(() => ({ ... - assertRetainedCurrent: assertRuntime, - assertTransactionCurrent: assertRuntime, - assertCurrent: assertRuntime, + assertRetainedCurrent, + assertTransactionCurrent, + assertCurrent, }));As per path instructions, tests must prefer observable outcomes through the public boundary and must flag broad mocks that bypass the behavior under test.

Outcome
This follow-up will reduce Hermes stopped-recovery lifecycle and inference currentness latency. It preserves the merged Slice 6 forward behavior, rollback, final semantic route, and readiness publication.
The initial commit establishes the review branch and scope. It does not change production or test bytes.
Reason
The exact Slice 6 Brev result reduced forward recovery from 62.775 seconds to 3.868 seconds. The remaining stopped-recovery owners are lifecycle at 35.173 seconds and inference excluding forward at about 32.559 seconds.
