fix(readiness): measure the reuse window from collection completion

[laitingsheng]

Summary

A readiness collection stamped its start time, so a probe slower than the 30-second reuse window aged out the facts it had just gathered, and no retry could succeed. Rebuild then had no working path at all: a running gateway failed the readiness gate, and a stopped gateway failed the route check, because a gateway that could not answer was treated as a route mismatch. The window now starts when collection finishes, the preflight checkpoints collect gateway facts again instead of rescoring an old snapshot, and only a genuine provider or model mismatch stops a rebuild.

Related Issue

Fixes #9310

Changes

• Measure the host and gateway reuse window from collection completion. collectGatewayObservations and collectHostObservations record completedAt, and projectGatewayReadiness and projectHostReadiness measure age from it. An observation set held past the window while another collection runs is still rejected.

• Replace refreshGatewayReadinessProjection with a real collection at both preflight checkpoints in runReadinessGatedRuntimePreflight. The removed function rescored the original snapshot against a newer clock, so it could only ever downgrade a projection and never re-observe. This costs two extra gateway collections per onboarding or rebuild run.

• Separate a gateway that cannot answer the route query from one that answers with another provider and model. readInferenceRouteState returns matched, mismatched, or unanswered, and preflightAuthoritativeRebuildTarget stops only on mismatched. An unanswerable gateway defers to authoritative onboarding, which configures and verifies the recorded route before it recreates the sandbox.

• Remove the reusable snapshot flag from both collectors. No collector ever set it to true, so the staleness guard that read it was unconditional and its exemption was unreachable. Removing it changes no behavior.

• Record the measured age and the applied window on host.probe.stale and gateway.probe.stale, and the gateway collection duration as collectionMs on gateway.owner. The previous report stated only that the window was exceeded, which left the reported failure undiagnosable.

• Add src/lib/readiness/observation-age.ts. Its current consumers are src/lib/readiness/gateway.ts and src/lib/readiness/host.ts, which applied the same window rule and emitted the same evidence separately. src/lib/readiness/gateway.test.ts, src/lib/readiness/host.test.ts, and src/lib/readiness/system.test.ts protect the shared behavior.

• Synchronize the branch with current main and pass the messaging dependency object through recorded-channel reuse. This fixes the TypeScript failure from the merged fix(onboard): retire a messaging channel preset the host no longer configures #9296 interaction; the affected messaging tests protect the dependency contract.

• Retain raw host and gateway snapshots through runtime admission, project both against one final clock, recollect host facts that age out during gateway collection, and fail closed if the paired gateway facts then age out. The readiness-gated preflight tests cover both outcomes.

This reverses the slow-collection rejection introduced by #8738, which closed #7411. That issue converges onboarding, gateway diagnostics, and doctor on shared readiness checks; it requires revalidating non-resume-safe facts before effects, and does not require rejecting a collection for its own duration. Both of that issue's freshness requirements still hold. One property does change: a collection whose probes span longer than the window carries that much skew between its first and last fact, and no longer stops the run. collectionMs reports that duration instead.

Warnings

Warnings do not block.

PRA-1 Warning — Cover expiry after the paired-readiness retry

• Location: src/lib/onboard/fatal-runtime-preflight.test.ts:507
• Category: tests
• Problem: The paired-readiness tests cover one recollection cycle, but they do not cover a second gateway collection that ages the newly recollected host snapshot past the 30-second window.
• Impact: A later change can admit host and gateway facts that cannot form a fresh pair, then start GPU or bridge probes with stale host evidence.
• Recommendation: Add a readiness-gated preflight test where the retry gateway collection exceeds the reuse window after host recollection. Assert that admission exits and does not run GPU or bridge effects.
• Verification: Inspect collectAdmittedReadinessPair and run the focused fatal-runtime-preflight test with a clock that advances during the retry gateway collection.
• Test coverage: A deterministic clock-controlled test that makes the second gateway collection exceed 30 seconds after host recollection, then verifies fail-closed admission before GPU validation and bridge/DNS probes.
• Evidence: src/lib/onboard/fatal-runtime-preflight.ts:350-370 recollects the host and gateway once when the first paired projection has stale host evidence. src/lib/onboard/fatal-runtime-preflight.test.ts:507-556 tests host and gateway recollection, but neither test advances time during the retry gateway collection after host recollection.

Completion-based readiness freshness src/lib/readiness/gateway.ts, src/lib/readiness/host.ts, src/lib/readiness/observation-age.ts, src/lib/readiness/index.ts, src/lib/readiness/*.test.ts, docs/reference/system-readiness.mdx	Gateway and host snapshots now use completedAt. Shared age utilities report stale evidence with windowMs and ageMs. Slow collections remain admissible when completed observations are fresh.
Tri-state inference-route rebuild validation src/lib/onboard/inference-route.ts, src/lib/onboard/authoritative-rebuild-target.ts, src/lib/onboard.ts, src/lib/onboard/*inference-route*.test.ts, docs/manage-sandboxes/recover-rebuild-sandboxes.mdx	Route checks now distinguish matched, mismatched, and unanswered states. Rebuild preflight rejects mismatches but permits unanswered routes for deferred recovery.
Collected runtime preflight readiness src/lib/onboard/fatal-runtime-preflight.ts, src/lib/onboard/machine/preflight-gateway-authority.ts, src/lib/onboard/fatal-runtime-preflight.test.ts, src/lib/onboard/machine/preflight-gateway-authority.test.ts, test/onboard-inference-reconciliation.test.ts	Runtime preflight carries gateway and host snapshots with projections, recollects stale paired facts, and repeats admission after GPU proof.
Supporting test wiring src/lib/onboard/machine/handlers/sandbox-messaging.test.ts, test/e2e/support/e2e-collaborator-permission-retry.test.ts	Test dependencies and authorization messages use the updated fixture and operation names.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to dc2ae

The readiness-gated preflight still receives a gateway projection where the updated path requires collected gateway facts, so production onboarding or rebuild flows may fail or make an incorrect admission decision. This is a concrete integration correctness risk that should be resolved or explicitly accepted before merge.

Reviewed exact head 544da174a8937fff6b5de471cea3591e082777ae.

The completion-based reuse window fixes the impossible slow-probe retry loop while retaining a bounded hold-time check between collections. The rebuild route-state change is also safe in the reviewed flow: a live, contradictory provider/model remains a hard failure; an unanswered gateway proceeds only into authoritative onboarding, which configures and verifies the recorded route before sandbox recreation.

Security review:

1. Secrets/credentials: PASS — no credential material or new secret flow.
2. Input validation/sanitization: PASS — invalid and future completion timestamps fail closed with unknown age; readiness report text remains bounded and sanitized.
3. Authentication/authorization: PASS — gateway authority is still resolved and bound before readiness and route checks.
4. Dependencies: PASS — no dependency changes.
5. Error handling/logging: PASS — mismatched and unanswered route states are kept distinct, errors remain bounded, and no private gateway state is newly exposed.
6. Cryptography/data protection: PASS — no cryptographic or persisted sensitive-data change.
7. Configuration/security headers: PASS — no header change; the exact recorded provider/model remains the authoritative route target.
8. Security testing: PASS — focused tests cover slow collections, stale held facts, route mismatch, unanswered route handling, and prepared recovery deferral. The advisor's invalid/future timestamp coverage suggestion is non-blocking because the fail-closed implementation is direct and documented.
9. System security: PASS — no destructive sandbox effect is admitted by a contradictory live route, and authoritative onboarding repairs and verifies an unanswered route before recreation.

Cross-issue sweep: no related open issue requiring a link or new filing was found.

The repository validation, static checks, TypeScript build, CLI shards, and focused author verification are green. The reported code-growth and hardware/self-hosted E2E failures do not expose a defect in this change.

461-472: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Consider dropping the redundant gateway collection at Line 468.

runReadinessGatedRuntimePreflight now performs four gateway collections per run: Lines 461 and 468, plus one inside each collectAdmittedReadinessPair call at Lines 472 and 510. Each collection runs live owner, port, and attachment probes. The projection from Line 468 is used only to derive managedGatewayReadiness for the first host collection, and the pair admission at Line 472 immediately collects again and replaces both values.

Reuse gatewayBeforePreparation for that first host collection, or let collectAdmittedReadinessPair own the post-preparation collection.

Return the complete gateway collection from the production adapter.

This code now requires both collectedGateway.projection and collectedGateway.snapshot. The supplied src/lib/onboard/machine/preflight-gateway-authority.ts:77 adapter still returns only (await collectGateway()).projection. Update that adapter to return the full CollectedGatewayReadiness value. Add a wiring test through runReadinessGatedRuntimePreflight.

Suggested contract fix

-const collectGatewayReadiness = async () => (await collectGateway()).projection;
+const collectGatewayReadiness = async () => await collectGateway();

Also applies to: 368-373

Retire the direct runFatalOnboardRuntimePreflight path or document its contract.

runReadinessGatedRuntimePreflight is the production entrypoint. It calls runFatalOnboardRuntimePreflight only with deferEffectfulChecks: true, so refreshOnboardHostReadiness is not a production compatibility path. Keep the shared host-admission logic, but remove the direct exported path and its effectful refresh branch if no external contract requires them. Otherwise, document the bounded compatibility window, retirement issue, exit criteria, and public-boundary coverage.
