Outcome

Prevent arbitrary qualification refs from supplying the secret-bearing cleanroom verifier while preserving immutable candidate package testing and the complete Fleet board.

Scope

  • emit a bounded, no-secret qualification request artifact from the candidate/manual ref;
  • run the secret-bearing verifier and Fleet RelayFlow only from github.workflow_sha on the trusted default branch;
  • bind repository, workflow name/path, event, original actor, rerun actor, branch, SHA, run attempt, one complete artifact listing, artifact digest, producer payload, and manifest;
  • hydrate candidate packages as immutable product input without checking out candidate source;
  • normalize downloaded candidate metadata to private mode through no-follow descriptors before hydration;
  • scope provider credentials to the Fleet execution step and use the trusted default-branch CLI for fallback cleanup;
  • land the 94-operation/two-attempt Fleet verifier and its fail-closed evidence gates on the trusted branch.

No candidate or Fleet qualification is claimed by this prerequisite.

Validation

  • focused qualification suite: 114 passed, 3 skipped; mode-hardening subset: 52 passed, 3 skipped
  • exact-head full Vitest currently blocked by Relay's locked @relayfile/client@0.10.27: 2518 passed, 25 skipped, 1 stale-daemon/lsof failure reproduced; the published 0.10.54 consumer-floor prerequisite must land before this PR can be green
  • npm run build:core: passed
  • npm run typecheck: passed before the mode-only workflow/helper follow-up
  • Actionlint, Prettier, and git diff --check: passed
  • configured candidate Fleet graph: 23 steps / 19 waves, with candidate npm/source-broker preparation absent
  • source candidate Fleet graph: 25 steps / 21 waves
  • exact base RelayFlow arm: bug / trusted_cleanroom_runner_missing
  • exact head RelayFlow arm: fixed / trusted_cleanroom_rejects_unapproved_ref_execution

Part of #1682. #1665 will consume this trusted path before any live Fleet credit or merge.

RelayFlow Proof

  • Change type: bugfix
  • RelayFlow case: 1682-trusted-cleanroom-runner

Note

High Risk
Changes CI trust boundaries, secret scoping, and candidate execution isolation for release qualification; mistakes could leak credentials or run untrusted code with Fleet/Cloud access.

Overview
Moves release cleanroom qualification onto a trusted default-branch verifier so candidate refs can only submit a bounded, no-secret request while secrets, Fleet proof, and cleanup run from github.workflow_sha.

A new request workflow uploads an immutable qualification request artifact; a workflow_run consumer validates actor/ref/artifact binding, re-checks cross-repo producer digests, hydrates the packed candidate install (not candidate source), seals verifier vs candidate roots, and runs the Fleet RelayFlow with provider credentials scoped to that step. Fallback cleanup is a separate job that rediscovers run-scoped workspaces and deletes only create-step-owned IDs with cascade evidence.

Candidate CLI inventory is collected out-of-process via a permissioned Node worker, optional Linux mount/network namespace sandbox (read-only candidate root, masked verifier checkout), and a network-blocking preload so inventory work cannot reach the network.

Also exports and hardens signalProcessTree in process-runner.mjs (macOS EPERM/zombie cases, fail-closed termination). Minor repo hygiene: .gitignore for broker platform bins and tracking workflows/verify-fleet-daytona.ts. Completed agent trajectory metadata is added under .agentworkforce/.

📝 Walkthrough

Walkthrough

The PR adds trusted cleanroom request and consumer workflows, strict qualification and artifact validators, secure candidate installation and file handling, Fleet verification orchestration, runtime evidence checks, cleanup verification, and comprehensive tests.

Changes

Trusted cleanroom qualification

Layer / File(s) Summary
Request trust and ref binding
.github/workflows/relay-cleanroom-qualification-request.yml, .github/workflows/relay-cleanroom-qualification-consumer.yml, scripts/verify-features/relay-cleanroom-qualification-request.mjs, tests/relayflows/cases/1682-trusted-cleanroom-runner/*
Requests use bounded artifacts. Validators bind approved actors, workflow runs, manifests, artifact digests, and trusted checkouts.
Qualification artifacts and candidate installation
scripts/verify-features/qualification-*.mjs, scripts/verify-features/relay-package-qualification.mjs, scripts/verify-features/relay-candidate-install.mjs, scripts/verify-features/safe-file.mjs
The PR validates producer artifacts, manifests, package payloads, candidate installs, hashes, semver, file identities, permissions, and symlink safety.
Fleet inventory, permissions, and execution
workflows/verify-fleet-daytona.ts, scripts/verify-features/fleet-*.mjs, scripts/verify-features/fleet-candidate-mount-sandbox.sh, tests/relayflows/cleanroom/*
The Fleet workflow validates the CLI inventory, restricts provider networking, runs Daytona attempts, collects evidence, reviews results, seals campaigns, and enforces a green verdict.
Consumer qualification and cleanup
.github/workflows/relay-cleanroom-qualification-consumer.yml, scripts/verify-features/qualification-capabilities.mjs, scripts/verify-features/qualification-effect-evidence.mjs, tests/fixtures/*
The consumer validates runtime capabilities, composes qualification effects, verifies workspace lifecycle evidence, and records independent cleanup results.
Supporting records and metadata
.agentworkforce/trajectories/completed/2026-09/*, .gitignore, tests/relayflows/cleanroom/snapshot-external-package-pins.json
The PR adds trajectory records, package pin snapshots, marker files, and repository ignore exceptions.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to 01406

A wildcard host could widen reviewer network access, and a permissive test may miss broken qualification wiring. These bounded issues should be addressed before relying on the cleanroom qualification.

The tarball label is a sentence fragment, so composed errors are garbled. readRegularFileNoFollow appends its own text to label. A symlinked tarball produces candidate tarball is not a regular file: @agent-relay/config must not be a symbolic link. Every other call site passes a noun phrase, such as candidate broker.

Make assertDeepEqual insensitive to key order.

assertDeepEqual compares JSON.stringify output. JSON.stringify preserves insertion order, so two objects with the same entries in a different order are reported as a mismatch. Two call sites depend on this behavior:

  • Line 192-202 compares checkout.with against an object literal whose keys are path, ref, persist-credentials. A benign key reorder in .github/workflows/relay-cleanroom-qualification-consumer.yml makes the proof case throw.
  • Line 140-144 compares Object.keys(requestWorkflow.on), which also binds YAML declaration order.

Use a structural comparison so the case fails only for a real contract change.

♻️ Proposed order-insensitive comparison
+function canonical(value) {
+  if (Array.isArray(value)) return value.map(canonical);
+  if (value && typeof value === 'object') {
+    return Object.fromEntries(
+      Object.keys(value)
+        .sort()
+        .map((key) => [key, canonical(value[key])])
+    );
+  }
+  return value;
+}
+
 function assertDeepEqual(actual, expected, label) {
-  const left = JSON.stringify(actual);
-  const right = JSON.stringify(expected);
+  const left = JSON.stringify(canonical(actual));
+  const right = JSON.stringify(canonical(expected));
   if (left !== right) throw new Error(`${label} mismatch: ${left} !== ${right}.`);
 }

If the trigger order in on must stay fixed, keep that one assertion on the raw key array.

Share the scale-corpus constants with the capability gate.

SCALE_FILES, SCALE_DIRECTORIES, SCALE_BYTES, and SCALE_MANIFEST_SHA256 are duplicated as literals in scripts/verify-features/qualification-capabilities.mjs (lines 80-83). Both modules must agree, or the gate accepts evidence that this validator rejects. Export the constants from one module and import them in the other.

Exact head 2094aa093563e786fcc63b420cf4008a9f975716 fixes both hosted failures without weakening the trust boundary:

  • RelayFlow case runners are dependency-hermetic again. The case no longer imports the repository-only yaml package from an isolated checkout; it uses a fail-closed workflow-YAML subset parser from the exact-head harness. Regressions cover structural mappings/sequences, block commands, comments/quoted lookalikes, duplicate keys, and unsupported flow mappings. Manual exact base/head observations produce the declared trusted_cleanroom_runner_missing / trusted_cleanroom_rejects_unapproved_ref_execution signatures.
  • The CodeQL TOCTOU annotation in safe-file.test.ts is removed by asserting content and mode through readRegularFileNoFollow's single verified descriptor instead of lstat(path) followed by readFile(path).
  • Focused: 17 passed, 3 platform skips. Typecheck, Prettier, actionlint, and diff check pass. Full suite with the required published @relayfile/client@0.10.54 staged: 163 files passed / 2 skipped; 2522 tests passed / 25 skipped.

The PR remains blocked from merge until Relay issue #1684 lands a reproducible 0.10.54 dependency floor/lock and the exact-lock full suite is rerun. No qualification or Fleet credit is claimed.

actions/download-artifact commit d3f86a106a0bac45b974a628896c90dbdf5c8093 artifact digest mismatch warning fail source code

Length of output: 8731


@khaliqgant I found one trust-boundary issue.

  • High — Fail closed on request-artifact digest mismatch. In .github/workflows/relay-cleanroom-qualification-consumer.yml, Line 73 downloads the selected request with actions/download-artifact@d3f86a106a0bac45b974a628896c90dbdf5c8093. This pinned v4 action reports a digest mismatch as a warning, not a step failure. scripts/verify-features/relay-cleanroom-qualification-request.mjs only validates the API digest format and copies it to requestArtifactDigest. It does not verify downloaded request bytes against that digest. As a result, the trusted consumer can accept request bytes that do not match the selected artifact digest. Download the artifact archive directly and verify its SHA-256 before extraction, or use an artifact action revision and configuration that fails on digest mismatch.

I verified the exact head. The local YAML parser removes the isolated-checkout dependency on yaml. The descriptor-based safe-file assertion also removes the reported test TOCTOU pattern.

Remount both candidate-install binds read-only.

The sandbox creates both binds inside its mapped user and mount namespaces, so it can remount them. Protect the staging bind as well as the final bind. Otherwise, the staging path remains writable if permission restrictions change. Keep $candidate_cwd writable.

Independent review blocks merge at exact head 67d60cb despite the expanded 120-op matrix and complete 29/29 CLI-leaf mapping. P1 gaps: final cleanup does not reject unexpected agent identities or re-list/reject unexpected Fleet nodes; node-down-timeout does not require its computed stopped result and node-down-force restores without proving stop; attach reconnect accepts repeated/cached worker-name output instead of unique first/second markers. P2: Fleet history does not require actual history evidence, and release-timeout has no dedicated operation. A repair agent is adding fail-closed regressions; live two-Daytona qualification remains pending after code signoff and Cloud prerequisites.

Hosted RelayFlow proof run https://github.com/AgentWorkforce/relay/actions/runs/34356743512 reached Cloud, created outer run d2952c71-9891-4891-acc7-8c0ba8cb4668, then failed before any sandbox dispatch with the typed error: Relaycast workspace key repair failed, HTTP 503 database temporarily overloaded. Cloud status confirms sandboxId is null. This is the production prerequisite addressed by merged Cloud #3483; its production deploy is still in progress. The next #1683 head will rerun only after that deploy is green.

Exact-head hosted proof update for 54dd081: Actions run 34364211839 failed outside the Fleet harness after its base arm completed. Cloud run 77b370d9-2d9e-48e6-9284-5377ad078077 hit Relayfile HTTP 410 cursor_expired on mount notify flush from the Cloud Daytona snapshot pinned to relayfile 0.10.55; WebSocket setup also returned 403 and the fallback reused the expired cursor. Relayfile issue #482 now carries the exact evidence. Both step sandboxes cleaned; the terminal outer sandbox leaked and was manually deleted after exact label verification. Separately, fresh exact-head code review found a P1 candidate credential-isolation gap; a red-first repair is in progress. This PR remains held pending both fixes and a new exact-head cleanroom proof.

A second exact-head blocker is confirmed in Package Validation run 34364116217: Standalone macOS Smoke failed during standalone up with Unable to connect while all non-live package checks were green. This is the recurring live-Relaycast merge-gate nondeterminism tracked by #1562, not a Fleet harness assertion. The repaired head will rerun it, but the PR remains held unless the exact check is green and the broader cleanroom proof completes.

Resolved the two current Cursor threads in 3c32ffb:\n\n- node-workflow-sync-changed now requires the exact run ID and hasChanges === true after the deliberate workflow mutation; the deterministic regression rejects false and mismatched results.\n- The no-board lifecycle branch now emits all 10 lifecycle/history records as blocked, including the five newer operations, rather than leaving the evidence matrix incomplete.\n\nValidation: focused qualification fixtures 103 passed / 4 platform skips; npm run typecheck; targeted Prettier; exact-head trusted-cleanroom proof reports trusted_cleanroom_rejects_unapproved_ref_execution. The Cloud RelayFlow proof is still intentionally unclaimed pending Cloud #3515 deployment.

Resolved the fresh Cursor workflow-run-ID thread in 79d112d. The missing-ID fallback now derives every remaining workflow operation using NODE_WORKFLOW_OPERATION_IDS.slice(1); a runtime FleetBoard.nodeWorkflows() regression drives that exact path. The same commit makes both exact-owned fallback workspace deletes use always(), with a parsed workflow contract test. Validation: 118 focused tests passed / 4 platform skips, typecheck, Prettier, diff check, trusted-default proof, and Veto triple scan pass.
