feat(messaging): add explicit enrolled Codex SSH peers

[phillipod]

Summary

• Follow the merged local foundation (feat(messaging): add local Codex queued session messaging #6544) with CLI-only Codex-to-Codex messaging across individually enrolled SSH peers. Refs feat(messaging): coordinate Codex and Claude sessions across enrolled hosts #6478; this does not close the broader proposal.
• Add explicit enable, confirmed fingerprint enrollment, safe peer listing/removal/status and foreground ocx message serve. Normal proxy startup and local messaging remain inactive with respect to remote resources.
• Reuse Remote Link's SSH policy, with separately owned forward/return tunnels and expiring return leases. A receiving node can reply without a second SSH login.
• Use protected directional capabilities and mutual proofs on the actual loopback connection before native attachment. Discovery, final loaded-recipient revalidation and experimental thread/queue/add share one connection; unknown outcomes are never replayed.
• Bound resources across all peers and join invocation-owned teardown. Exclude mesh/dashboard/cache controls, isolation, Claude, managed skills, prompt policy, idle watches and native daemon lifecycle changes.

This protected gateway is an OpenCodex wrapper protocol, not a native WebSocket endpoint: raw codex queue --remote does not implement its handshake. Native daemon authentication/configuration is unchanged. Sender session identity remains descriptive; it does not grant user approval or establish same-UID isolation. Foreground ownership and the remote contracts remain proposed maintainer review boundaries.

Verification

Current rebase qualification — roster conflict follow-up

Current candidate: 3e5925609e6273380a089aedd4ff9ea49cc4c2f3, based on latest fetched upstream dev a63267c1349f178b52cf7e5d4d158e8f1e4be075.

• Followed the maintainer's conflict instructions: preserved both the new dev registrations and the messaging roster in tests/fixtures/test-layout-expected.json and scripts/test-layout/layout.json. Independently compared parsed golden mappings with both inputs: all 2,231 dev entries and 2,226 prior-head entries are retained; merged golden and explicit layout agree on 2,239 entries, with no duplicate golden keys.
• Only layout/golden conflict resolutions changed the contribution patches. Messaging/SSH runtime and messaging regression files are byte-identical to the prior public head, confirmed by diff/range-diff; no registration was dropped to make the merge clean.
• Final-head Linux/Bun 1.4.0: 547 passed / 6 skipped / 0 failed, 5,642 assertions across 38 files, 93.99 seconds. Typecheck, structure check, generated-surface check, privacy scan and diff whitespace check passed. Docs built 569 pages, checking 79,386 internal links, in 40.69 seconds. Existing dependencies were reused; no fresh install qualification is claimed.
• Full and changed-suite evidence remains incomplete/nonpassing, as recorded below; those lanes were not rerun in this roster-only correction. The prior 180-second changed-graph run had failures and no complete receipt; no unrelated/environment-only classification is inferred. Focused validation is the bounded resource exception for this conflict-only rebase, not a broad-suite pass.
• Native-daemon, real-SSH and macOS qualification were not rerun on this head. Earlier interoperability receipts retain their original pins below; they are not final-head qualification. Exact-head hosted CI, maintainer sponsorship, credential-boundary signoff and acceptance remain separate. Existing review threads are resolved; this does not grant approval or enable paused CodeRabbit reviews.

Earlier rebase qualification — retained with its original pins

Rebase qualification — 2026-10-12

Current candidate: a6206e866302cdafde64b0090c5fdd73283d1743, rebased onto upstream dev 744678faebe3c7fd676beee153c29b929df3b73a. The owner's generated-surface conflict was resolved with bun run skill:surface; range-diff shows no change to messaging runtime or test patches. The later two-commit base advance replayed all twelve contribution commits unchanged. No deployment or local integration branch change is included.

• Final-head Linux/Bun 1.4.0: 277 passed / 3 skipped / 0 failed, 4,305 assertions across 21 files; typecheck, privacy scan, structure check, generated-surface check and docs build passed. Docs built 569 pages and checked 79,377 internal links. Existing dependencies were reused; no fresh dependency-install qualification is claimed.
• Intermediate rebased head 08cbb2147433c1dec7ecbda5a74ae85fcb87dedb on base 8d12a3cb0c9ead696e1179fc9558aa79d894021f: wider messaging/shared-link/CLI/management/guard lane 547 passed / 6 skipped / 0 failed, 5,632 assertions across 38 files. Disposable generated-key real-SSH duplex check: 1 passed / 0 failed, 10 assertions. Messaging and SSH sources are byte-identical at the final head; these remain explicitly intermediate-head receipts, not rerun final-head interoperability evidence.
• On that intermediate head, timeout --signal=TERM --kill-after=15s 180s bun run test:changed selected 1,071/2,245 files and ended incomplete/nonpassing (outer exit 124; wrapper 143). It emitted 18 failure entries involving GUI pairing, Bun PATH provenance, catalog drift healing and catalog picker convergence before termination; there is no final suite-count receipt. No fresh base comparison was performed for these failures, so they are not classified as unrelated/environment-only. This broad lane also is not a final-head pass.
• Full-suite, real native-daemon, macOS, final-head real-SSH and exact-head hosted CI remain unqualified in this rebase round. Focused validation is the bounded scope exception for a rebase whose conflict resolution only changes generated documentation; the broad lane's ceiling/failures remain explicit. Maintainer sponsorship, independent credential-boundary review and acceptance remain separate.

Final-head commands (all completed successfully):

bun run typecheck
bun run privacy:scan
bun run structure:check
bun run skill:surface:check
bun test tests/codex-integration/messaging-*.test.ts tests/clients/link-ssh-argv.test.ts tests/clients/link-ssh-argv-discovery.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/ci-workflows/file-size-ratchet.test.ts tests/ci-workflows/structure-ssot.test.ts tests/ci-workflows/skill-ocx.test.ts
(cd docs-site && bun run build)

The first scoped regression attempt was blocked by the sandbox's socket-listen restrictions and failed; the same broader lane completed successfully with escalation using disposable fixtures. No live daemon or enrolled production peer was used. CodeRabbit's existing threads are resolved and its last review had no actionable comments, but automatic reviews are paused. Readiness must be freshly assessed against the new head.

Historical qualification (retained with its original pins)

Candidate: 70822541db44df1c49add7600e9953dc4387b975 on feat/codex-remote-contribution, based on upstream dev 9b6f4b2632492b3df637dccc009d6a01ed47c85d (zero commits behind at publication preflight). Fetch/rebase confirmed the branch was already up to date. The latest correction shares strict local-journal interpretation between enrollment retries and recovery: malformed JSON/outer/nested records and invalid values produce invalid_enrollment_journal, preserve original bytes and send no enrollment control request. Safe storage reads and lock failures retain their own classifications. The deployed experiment is unchanged.

• Passed on this candidate: typecheck, privacy scan, structure ownership check, generated operating surface check, and public docs build (569 pages, 79,312 internal links, 1m 0s).
• Current messaging regressions and explicit layout/size/ownership/surface guards: 245 passed, 2 skipped, zero failed; 4,096 assertions across 19 files, 79.17 seconds. Enrollment-only qualification also passed: 43 tests, 277 assertions. The 12 new cases cover malformed journals at enrollment/CLI boundaries plus unsafe-file/busy-lock classification; ten diagnostic cases failed against the preceding implementation and pass after the fix. They check byte preservation, unchanged local/remote state, zero enrollment control exchanges and sanitized output. The preliminary host-key probe may still occur.
• Historical broader consumer qualification at previous head 33df9692d, not rerun wholesale for this journal-only correction: messaging regressions, shared Remote Link SSH consumers, CLI/management routes and explicit source-oracle/layout/size/ownership/surface/runner guards: 486 passed, 6 skipped, zero failed; 5,342 assertions across 36 files, 92.08 seconds. Opt-in SSH/native fixtures run separately; Windows-specific cases remain skipped on Linux.
• In that previous correction, five targeted regression cases failed against the preceding implementation and pass after the correction (39 assertions): probe argument policy, overlapping revocations, failed remote-cleanup scratch disposal, and CLI preparation failure before/after publication. Preparation failures start no SSH helper and still report committed local removal with transaction-qualified remote cleanup guidance.
• Current real loopback SSH enrollment/duplex request-response with HashKnownHosts=yes in the isolated SSH configuration: 1 passed, 10 assertions, 5.98 seconds in a disposable generated-key fixture. Native endpoints are offline Unix fixtures, not live agents or deployed nodes. No user known_hosts file, SSH configuration, credential or service was changed.
• Current changed-graph run incomplete/nonpassing: timeout --signal=TERM --kill-after=15s 180s bun run test:changed selected 1,061 of 2,233 files (53 changed files) and reached the explicit ceiling (outer exit 124; wrapper exit 143), without a final suite-count receipt. It reported two GUI pairing local-intent failures and the Bun PATH-provenance selection failure. These match the three failures previously reproduced on the unmodified base; that historical comparison does not make this incomplete run passing.
• Previous-head changed-graph run incomplete/nonpassing: timeout --signal=TERM --kill-after=15s 180s bun run test:changed selected 1,061 of 2,233 files and reached its explicit ceiling (outer exit 124, wrapper exit 143), with no final suite-count receipt. It reported settings/Anthropic timeouts, cascading spend-ledger owner-home conflicts in bearer-admission cases, two GUI pairing local-intent failures, and Bun PATH-provenance selection failure.
• Historical isolated follow-up of that previous run's five failure-bearing files: 218 passed, 3 failed, 1,383 assertions, 46.65 seconds. Settings, Anthropic and bearer-admission cases pass in this invocation. The same three persistent failures (two GUI pairing cases and Bun PATH provenance) reproduce on an unmodified checkout of the exact upstream base with the same Bun/dependencies: 37 passed, 3 failed, 131 assertions. That comparison does not establish the root cause or turn the broader run into passing evidence. No assertion or product/test timeout was weakened.
• Full-suite validation remains incomplete, not passing. An earlier frozen implementation run reached the existing 900-second parallel-lane limit (exit 124); serial lanes were not reached and no final suite-count receipt exists. That historical run included a contribution layout-size failure subsequently fixed without raising its cap, plus unchanged-path Responses, CodeBuddy, replay, image/audio and runtime-provenance failures/timeouts not proven environment-only. Focused regressions and explicit non-import-graph guards cover this correction; broader exact-head hosted CI remains required.
• Earlier stock codex-cli 0.160.1 protected-gateway qualification accepted a request, completed a synthetic turn and returned a correlated response in a credential-free home: 1 passed, 6 assertions. This is historical evidence, not a native-binary rerun at this head. Executable SHA-256: f34a4d2301892ae96c90097786bfe5dc269f187b6f69faf42a7b357b8c081e35.
• The earlier frozen implementation received a completed security diff scan with no accepted findings and separate architecture/authentication/transport reviews. Later boundary review led to transaction/revocation ordering, freshness, cleanup ownership and helper-budget corrections with focused regressions. The original sealed scan does not cover this head. The maintainer's independent 15-test process-lifecycle receipt at 1154affa5 remains scoped historical evidence, not whole-PR approval, sponsorship or independent credential-boundary sign-off.
• Linux fixture evidence only. macOS interoperability remains unqualified; Windows remote transport is unsupported. No production enrollment, service restart, skill migration or deployment was performed.

Explicit maintainer sponsorship and security review remain requested for enrollment, capabilities and gateway admission. Local validation does not replace that acceptance or required exact-head hosted CI. The PR remains draft with all four review-readiness boxes unchecked.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

• Required local validation passed; commands, results, and any full-suite exception are documented.

• I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).

• I resolved all correct Codex and CodeRabbit findings.

• My PR is ready for review.

Opened in draft. Required exact-head hosted CI, PR bot reviews and maintainer acceptance remain outstanding.

Summary by CodeRabbit

• New Features
  • Discover loaded Codex sessions and queue messages on explicitly enrolled SSH peers with --host; replies can route back to the originating machine.
  • Enable or disable remote messaging, check its status, and probe, enroll, list, remove, or abandon host enrollments.
  • Run a foreground messaging service to establish peer routes and support replies. Results distinguish queued, unknown, and not-sent outcomes; uncertain sends are not automatically retried.
  • Remote connections require confirmed host keys and use authenticated, bounded access.
• Documentation
  • Added guidance on enrollment, service operation, status, resource limits, and pending-enrollment recovery.
  • Clarified that remote transport is unsupported on Windows.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
Review comments at @src/cli/capabilities-agents-routing.ts:
- Around line 6-7: Update the `sessions` capability details in the routing
metadata to distinguish local discovery via the effective CODEX_HOME Unix socket
from `--host` discovery via the live foreground owner’s authenticated loopback
route. Preserve the existing Linux/macOS, no-daemon, and no-partial-directory
behavior, and regenerate the skill surface so its reference reflects the updated
detail.

Review comments at @src/messaging/remote-enrollment.ts:
- Around line 52-62: In handleEnrollmentControl, reject new enrollments with a
peer_capacity error when current.peers has reached REMOTE_LIMITS.peers, before
creating the incoming capability or pushing a peer; preserve the existing-peer
reuse path.
- Around line 85-104: Update the pending-journal handling inside withRemoteLock
to load the current enabled configuration before processing an existing journal;
delete journals whose generation differs from the current generation, then
continue enrollment, while retaining same-generation mismatch protection. Add an
explicit CLI path to abandon a same-generation pending enrollment and warn that
the remote side may need cleanup; update the disable/re-enable test and
documentation to reflect recovery behavior.

Review comments at @src/messaging/remote-files.ts:
- Around line 38-48: Update `createRemoteDirectory` to validate the
configuration-home parent with the trusted-ancestor check, allowing an existing
mode-0755 home, while retaining strict private-directory validation for
`messaging-remote`. Add an optional privacy setting to `checkRemoteDirectory`
and use it only for the parent check; keep the default strict behavior for the
remote state directory.

Review comments at @src/messaging/remote-owner.ts:
- Line 110: Update the `tunnels.exited` handler in the remote owner to retire
the owner when a published tunnel pair exits: after conditionally removing the
matching route, call `abort()` when `stopping` is false. Preserve the existing
route identity check so an obsolete tunnel cannot remove a replacement route,
and ensure owner retirement settles `finished` for the CLI.
- Around line 66-68: In the lease registration path, update the conflict check
after the successful `probe` so an authenticated lease from the same
`peer.machine.id` can replace an unexpired route with a different `generation`.
Keep rejecting routes with active `tunnels`, then store the new lease in
`routes`.

Review comments at @src/messaging/remote-ports.ts:
- Around line 21-22: Update the listener-table loop that opens `/proc/net/tcp`
and `/proc/net/tcp6` to treat `ENOENT` for `/proc/net/tcp6` as an empty table
and continue. For all other open failures, preserve fail-closed behavior by
throwing `remoteError` with the existing port-inspection error details.

- Around line 69-86: Update drain to apply the 64 KiB limit only to stdout;
after stdout overflows, record the output-limit failure once, discard subsequent
chunks, and keep reading both pipes to natural EOF. Preserve the first failure
when handling drain or input-write errors, and update close cleanup error
propagation so cleanup timeouts do not replace that original failure.

Scoped follow-up at 1154aff after the f5e91fe corrections: I ran Bun 1.4.0 test --no-env-file --isolate ./tests/codex-integration/messaging-remote-process.test.ts --timeout 10000 on the unchanged production head: 15 pass, 0 fail, 96 assertions.

The existing synthetic process seam exercises stdout overflow and aggregate exhaustion, large discarded stderr, first-failure preservation, stdin failures, TERM/KILL cancellation, leader exit with retained pipes, natural EOF, and persistent/transient helper accounting. Successful cleanup returns the capture failure and releases capacity; genuinely incomplete cleanup still returns cleanup_incomplete with the capture failure as its cause and retains capacity. The latter is important evidence, not an error to hide merely to match the overflow code.

Execution was globally serial with new private homes, CPUQuota=75%, MemoryHigh=1280M, MemoryMax=1536M, swap disabled, TasksMax=64 and a 60-second unit ceiling. Protected user configuration remained unchanged. The Darwin inspection branch uses a fake process/lsof result on Linux; it does not qualify real macOS behavior. No SSH daemon, live native Codex/provider/account, security/privacy scan, or author-branch change was used.

I also read the current enrollment journal and file/directory-sync changes plus their regressions. Store/enrollment execution was deferred while another build was active, so I am not adopting the author's broader 320-test receipt as my own. Current exact-head hosted workflows remain action_required. This is focused process-lifecycle evidence, not whole-PR approval, sponsorship or an independent credential-boundary sign-off; the Draft/full-suite/macOS coverage limits remain.

@Ingwannu — follow-up pushed at 33df9692dd4aae903732e94dbc67ab4ab31727d1, rebased onto dev 9b6f4b263. Your independent process-lifecycle receipt at 1154affa5 is retained as scoped evidence; the process cleanup distinction you highlighted is unchanged. This correction addresses the three new CodeRabbit findings: private SSH probe hashing, overlapping revocation scratch files, and the structure source map.

Current-head validation: 486 passed / 6 skipped / zero failed across messaging and shared-link consumers, plus the generated-key real-SSH round trip with HashKnownHosts=yes and typecheck/privacy/structure/surface/docs checks. Verification now records the exact head and commands.

The 180-second changed-graph run remains incomplete/nonpassing. Its five failure-bearing files yield 218 passed / 3 failed in isolation; the same three persistent GUI pairing/Bun-provenance failures reproduce on unmodified upstream dev (37 passed / 3 failed). This is comparative evidence, not an environment-only or whole-suite pass claim. Full-suite/macOS and hosted CI remain outstanding. No sponsorship, whole-PR approval or independent credential-boundary sign-off is inferred; the PR stays draft.

Scoped follow-up at current head 33df9692dd4aae903732e94dbc67ab4ab31727d1 (base dev 9b6f4b2632492b3df637dccc009d6a01ed47c85d).

The hashing correction is present in the shared src/link/ssh-argv.ts common options, and the shared argv assertion now checks HashKnownHosts=no. I also checked the new revocation delta: the scratch path is transaction-and-attempt-qualified, preparation is inside the receipt-preserving try/catch, and removal is attempted in finally. The new cases explicitly cover overlapping removals and preparation failures before/after publication. These are source checks, not independently executed SSH or fault-injection results.

remote-process.ts and its 15-case test file are byte-identical to the prior 1154affa5 checkpoint. My earlier 15-pass/96-assertion receipt remains scoped historical evidence; I am not relabeling it as a current-head whole-PR run.

Current-head target/hygiene jobs now complete successfully. Cross-platform CI 38105245986, Catalog contracts 38105245972, and React Doctor 38105245952 are still action_required. The issue has only the enhancement label, not maintainer-sponsored. Successful mechanical gates and the author's 486-case receipt do not supply my independent boundary signoff, full-suite/macOS qualification, or approval.

Local store/enrollment/shared-argv execution remains deferred because foreign Cargo/clippy/rustc builds are live. No SSH/native daemon/provider call, scan, branch change, sponsorship or approval was performed.

Independent local verification update — 2026-10-11

The previously deferred store/enrollment scope now ran at unchanged current production head 33df9692dd4aae903732e94dbc67ab4ab31727d1, together with the affected shared SSH argument tests:

bun test --no-env-file --isolate ./tests/codex-integration/messaging-remote-store.test.ts ./tests/codex-integration/messaging-remote-enrollment.test.ts ./tests/clients/link-ssh-argv.test.ts --timeout 10000

Bun1.4.0/Linux: 60 passed / 1 skipped / 0 failed / 392 assertions, across3 files, 5.87 seconds. The skipped case is PowerShell parsing and supplies no Windows qualification. The measured cases include file/directory sync ordering and uncertain-durability receipts, overlapping revocation scratch ownership/cleanup, preparation failure before/after publication, enrollment/revocation interleavings, and shared argv assertions for HashKnownHosts. CLI fault injection runs disposable child Bun processes; SSH runners and native RPC peers are synthetic. Local shell-prelude stubs are not real SSH/native agents. No real SSH, daemon enrollment, installed agent or provider call was used.

Execution was serial after prior owned test units terminated, with new private homes, effective CPU75%/memoryHigh1280MiB/max1536MiB/swap0/tasks64/nice10 and a finite120-second ceiling. IOWeight20 is configured but the user's cgroup has no delegated io controller; no effective I/O-weight claim. Protected user configuration remains unchanged. Production worktree is clean. This is a current-head three-file receipt, not a rerun/relabeling of the older 15-case process receipt, a full52-file review, macOS/real-SSH/native interoperability, root typecheck, full-suite or independent boundary signoff. Draft/CI/sponsorship holds remain; no approval or scan.

Scoped follow-up at current head 70822541db44df1c49add7600e9953dc4387b975 (trusted dev/base 9b6f4b2632492b3df637dccc009d6a01ed47c85d).

I inspected the five-file delta from 33df9692: enrollment retries now reuse parseEnrollmentJournal from the recovery reader. The interpretation catch covers malformed JSON, outer/nested records and invalid field values, while safe reads and lock acquisition remain outside it. Returning the parsed record preserves property order for existing exact transaction-ownership checks. The CLI and structure documentation describe preserved bytes, explicit recovery, separate storage/lock errors and the preliminary host-key probe accurately.

Independent Bun1.4.0/Linux execution on this exact head: bun test --no-env-file --isolate ./tests/codex-integration/messaging-remote-enrollment.test.ts --timeout 10000 — 43 pass / 0 fail / 277 assertions, complete file, 8.59 seconds. This includes all 12 newly added cases: five malformed-journal interpretations and five corresponding CLI diagnostics, plus unsafe-file and busy-lock classifications. The fixtures assert original journal bytes and local/remote state remain unchanged and no enrollment control exchange occurs. SSH/key probing is injected, native RPC peers are disposable Unix fixtures, and CLI children use the same isolated Bun; no real SSH, native daemon or account enrollment was executed.

Execution setup correction: my first attempt placed fresh homes/TMPDIR beneath a group-writable .tmp ancestor. The existing private-storage guard correctly refused that path before the intended journal assertions; I stopped only my isolated unit. I did not change shared-directory permissions or production code. A single corrected run used new mode700 roots under /tmp, retaining all hard caps and assertions, and produced the complete result above. No interrupted result is counted as passing.

Effective limits: serial CPU75%, memoryHigh1280MiB/max1536MiB, swap0, tasks64, nice10, finite120-second ceiling. IOWeight20 is configured but io is not delegated; no effective I/O-weight claim. Protected user configuration is unchanged and the exact-head worktree is clean.

This verifies the journal-diagnostic correction only. The prior 60-pass/one-skip three-file receipt belongs to 33df9692, not this whole new head. Current target/hygiene jobs pass, while Cross-platform38106635563, Catalog38106635581 and React Doctor38106635577 remain action_required. The author's changed-graph run remains incomplete/nonpassing. No independent full-PR/boundary signoff, new typecheck/full-suite/macOS/real-SSH validation, sponsorship, scan, workflow authorization or approval is claimed; Draft remains appropriate.

Merge-manager pass: this branch no longer merges cleanly into dev (checked against 8eb1fc3de3 with git merge-tree). Conflicting files:

• skills/ocx/references/01_management_surface.md — generated surface map: take dev's copy, then run bun run skill:surface and commit the result (bun run skill:surface:check is what CI asserts)

Please rebase onto the latest dev, resolve these, and rerun bun run typecheck, bun run structure:check and the focused tests before pushing. The review state is otherwise unchanged by this note.

Rebase follow-up checked against current trusted dev 3e58c2ce3ee5433901ed467fe87c32fb4b5c5e77 and candidate a6206e866302cdafde64b0090c5fdd73283d1743: git merge-tree --write-tree --name-only still exits 1, now with a content conflict in tests/fixtures/test-layout-expected.json. The earlier generated-surface conflict is not what this current comparison reports.

Please preserve both rosters in that golden file and ensure it agrees with scripts/test-layout/layout.json after rebasing; do not drop newer dev registrations to clear it. Requalify the final published head and keep the incomplete full/changed-suite and native/macOS scope explicit. No branch takeover, workflow authorization, sponsorship or credential-boundary sign-off is implied by this conflict check.

Scoped refresh at 3e5925609e6273380a089aedd4ff9ea49cc4c2f3.

Compared to my previous enrollment checkpoint70822541d, the remote messaging implementation and remote fixture files are unchanged. The shared SSH prelude changed through upstream integration: Desktop binary candidates precede PATH, candidates must pass --version, and unsupported remote platforms have a distinct125 status. My historical 43-pass/277-assertion enrollment receipt is not rebranded as current whole-PR or shared-prelude execution.

Current dev is3bb7a5612c and this head is 24 commits behind. The older golden/layout conflict is not a current conflict claim; latest target/hygiene successes do not replace fresh shared-SSH consumer coverage or executable CI. Cross-platform38303199450 remains action_required, independent gateway/enrollment boundary acceptance and macOS/native interoperability remain open. Please refresh the branch and head-bound readiness receipt before integration. No local tests were launched while foreign Cargo builds are active; no real SSH/native endpoint, scan, sponsorship, workflow authorization, approval or merge was performed.
