Standalone Rust native/ocx-child runtime & Home discovery/relay base
Rust ocx-child wire/journal conformance & base enrollment
The #8237 base layer landed on dev as f14a2c104; this branch merged dev (805647519, plain merge, no rebase) and now targets dev. The diff against dev is exactly this layer (51 files).
Connecting a disposable SSH devbox, container, or cloud VM through #remote or ocx link add previously required pre-installing ocx or manually copying ocx-child onto the Child beforehand (502 remote_ocx_missing), offered no one-click or --purge option to remove a planted binary on disconnect, and surfaced generic preflight errors when port 10100 or ~/.codex/config.toml was already owned externally.
This layer completes end-to-end lightweight Ephemeral Child onboarding and lifecycle UX:
Zero-preinstall SSH host inspection & atomic stdin planting: POST /api/link/probe and POST /api/link/confirm-host (allowMissing: true) inspect remote targetTriple (darwin-arm64, darwin-x64, linux-x64, linux-arm64, windows-x64) and classify runtimeKind (full, ephemeral, or missing). src/link/child-binary-source.ts verifies non-symlink ocx-child artifacts (OPENCODEX_CHILD_BIN_DIR, sidecar directories, host-matching local native/ocx-child release build, or SHA256SUMS-verified $OPENCODEX_HOME/cache/ocx-child/<version>/). When plant: true is authorized on POST /api/link/apply, Home streams the verified binary over SSH stdin into ~/.cache/opencodex/bin/ocx-child (0700 atomic write on POSIX) or %LOCALAPPDATA%\opencodex\bin\ocx-child.exe (inside OcxJob<= 8000 encoded chars on Windows, refusing symlinks and reparse points) — working even on air-gapped Children — and automatically purges a newly planted binary if enrollment fails.
Two-tier disconnect (fast detach vs --purge) & durable childKind: native/ocx-child (detach / disconnect --purge), DELETE /api/link/:id ({ purge: true }), and ocx link revoke --link-id <id> --purge delete the binary after restoring ~/.codex and stopping ocx-child serveonly when the executable resides inside the managed plant path (refusing symlinks, ancestor symlinks/reparse points, and foreign/system paths; using rename-aside + detached cmd.exe cleanup on Windows), while default disconnect keeps the cached binary for instant re-attach. LinkRecord persists childKind ("full" | "ephemeral") and projects it on GET /api/link/status (alongside gui-sessionhomeCodexSettingsDigest).
Actionable conflict diagnostics & CLI flags: Foreign listeners on childPort and external model_provider / user openai_base_url / model_catalog_json ownership in ~/.codex/config.toml map deterministically to 409 child_port_busy and 409 child_external_provider_conflict while leaving Child files untouched. ocx link add <alias> [--plant] prompts once on interactive TTY for bare hosts and requires explicit --plant alongside --expect-fingerprint in non-TTY automation.
#remote Dashboard UX across all 11 locales: Modularized #remote (RemoteLink.tsx, RemoteLinkSheet.tsx, RemoteLinkDialogs.tsx) and updated all 11 locale catalogs (en, ko, ja, zh, zh-TW, de, fr, pt, ru, tr, vi) with the Ready to plant lightweight agent confirmation card, Lightweight / Full install and Home settings synced / Sync needed badges on connected Child rows, specific conflict notices, and the Disconnect --purge checkbox + ~/.cache/opencodex/bin/ocx-child detach offline recovery command.

Maintainer follow-up head 805647519 (merge of dev after feat(link): add lightweight Rust ocx-child ephemeral Child relay and offline journal #8237 landed; same layer diff as 88424a8ba; at 805647519 re-ran cargo fmt, clippy -D warnings, cargo test 50 pass / 0 fail, 5 changed Bun test files + conformance + layout/Lab/ratchet/structure guards 123 pass / 0 fail, gui/tests/remote-link.test.tsx 53 pass, typecheck, lint:gui, build:gui, privacy, structure): plain merges of feat(link): add lightweight Rust ocx-child ephemeral Child relay and offline journal #8237's current head (79e4a1824) into this branch (d83dc2bcb, 53d58b903; no rebase), keeping feat(link): add lightweight Rust ocx-child ephemeral Child relay and offline journal #8237's lock order (lifecycle → CODEX_HOME owner lock → start gate), restoration identity rechecks and daemon generation commit. Fixes for review findings, each with a regression that failed first: docs and probe/CLI/GUI messages now state where a plantable build must come from (npm and desktop packages ship none); POSIX plant fails closed without a hash tool (sha256sum, shasum or openssl), hint hash_tool_unavailable; purge runs the managed binary with --json and requires purged: true, reports managed_child_missing/purge_incomplete, and refuses a full install with purge_unsupported instead of silently skipping; taking the lifecycle lock never changes permissions of a pre-existing OPENCODEX_HOME (lock file still owner-only, opened without following links); empty OPENCODEX_HOME counts as unset; enrollment-rollback purge keeps the binary and reports residual while attach-rollback.json or .ocx-child-owner.json exists; purge_unsupported is mapped in the GUI for all 11 locales. childKind joining strict RECORD_KEYS means a downgraded Home rejects links.json (same trade-off as remotePlatform, noted in structure/remote-link.md).

Pushed with --no-verify (no pre-push hook is installed). Local full suite NOT RUN on the shared host; hosted CI is the broad gate. NOT RUN: Windows execution of the PowerShell plant/purge scripts (decoded-script assertions only).

Documentation
Updated Remote Link guides with setup, disconnect, and agent-removal instructions.
This change adds verified ocx-child planting for bare SSH hosts, records child runtime kind in Remote Link state, and supports optional purge during disconnect. It updates CLI and GUI workflows, lifecycle safeguards, tests, and Remote Link documentation.
Changes: Ephemeral Child Remote Link
Layer / File(s)
Summary
Child lifecycle and managed purge native/ocx-child/src/*, native/ocx-child/tests/*
Detach can optionally purge a managed executable. The lifecycle lock moves to child.lock, and lock setup leaves existing home-directory permissions unchanged. Port and configuration conflicts use structured markers.
Artifact discovery and remote runtime operations src/link/child-binary-source.ts, src/link/remote-plant.ts, src/link/remote-windows.ts, tests/clients/link-child-plant-foundations.test.ts
Adds target-specific binary resolution and checksum validation, remote runtime inspection and planting, and POSIX and Windows cleanup commands. Tests cover artifact verification, planting, and purge boundaries.
Enrollment, link state, and removal src/link/store.ts, src/link/status-projection.ts, src/server/management/*, tests/server/link-enrollment-ephemeral-child.test.ts, tests/clients/link-ocx-child-e2e.test.ts
Missing-runtime enrollment requires explicit planting. The server verifies and installs the artifact, records childKind, compensates after failures, and supports conditional purge on link removal. Status can include the Home settings digest for GUI sessions.
CLI and GUI workflows src/cli/link*.ts, gui/src/remote-link-api.ts, gui/src/pages/RemoteLink*, gui/src/i18n/*, gui/tests/remote-link.test.tsx, tests/cli/*link*.test.ts
Adds CLI --plant and --purge handling, setup and disconnect dialogs, runtime and settings-parity badges, purge controls, translated messages, and workflow tests.
Documentation and project records docs-site/src/content/docs/guides/remote-link.md, docs-site/src/content/docs/ko/guides/remote-link.md, structure/remote-link.md, devlog/_plan/261107_ocx_child_plant_ux/*, scripts/test-layout/layout-clients.json, tests/fixtures/test-layout-expected.json
Updates the Remote Link guides and structure reference. Adds the roadmap, phase plans, audit/status record, and test-layout registrations.
lidge-jun/opencodex#8237: Adds the ocx-child runtime and contracts extended by this change, including lifecycle, conflict, and enrollment behavior.

Merge Risk: Moderate · up to 80564
Resolve artifact trust and lifecycle ownership before merging: overlapping enrollment can detach another Home’s Child, and writable artifact locations can supply untrusted executables. Cleanup failures can also leave misleading recovery state, older clients can lose status access, and changing the selected host can still plant on the previously confirmed computer.

Explanation
The title "feat(link): zero-preinstall SSH ocx-child planting, --purge detach, and #remote UX" matches the main change in the changeset. The PR adds the ability to plant a verified ocx-child binary over SSH on bare hosts, adds --purge removal of the managed binary on detach or revoke, and redesigns the #remote UI. The title names all three main parts. It is concise and specific, and it follows a conventional commit style. It is long (82 characters) but still a single readable sentence.

…record
Attach rollback restarted the prior relay and committed it before it
removed the rollback record, so the relay could serve while recovery
might still restore files underneath it. The restart now commits only
after the record is removed; an uncommitted relay is dropped and exits
if the removal fails. The structure doc names this ordering.
A control connection, accepted while every worker is busy, had only a
1-second per-read timeout, so a sender writing one byte per second held
its slot indefinitely and 256 such senders kept the authenticated
shutdown from being handled. Control mode now reads through the
existing DeadlineStream with a 2-second deadline that covers the whole
exchange, including the shutdown proof frame. The code comment and
structure text now state the bound and the connection cap precisely.
The parity socket can be registered for cancellation only after it
connects, and that connect could take up to the 5-second auth timeout,
longer than the 3-second wait stop_owned_daemon gives a relay to exit.
A request that carries a CancelSlot now connects with a 1-second bound;
one-shot lifecycle fetches keep the 5-second bound.
…king the lifecycle lock
Moving the lifecycle lock to $OPENCODEX_HOME/child.lock made every
FileLock acquisition call ensure_private_dir on OPENCODEX_HOME: attach,
sync, restart, and detach chmodded a shared home to 0700 on POSIX and, on
Windows, applied a protected owner-only DACL with inheritable ACEs that
propagated into a co-installed full OpenCodex tree, all before the
full-ocx conflict check.
FileLock now decides through lock_parent_action: a missing parent is
created private by create_private_dir_if_missing (0700, or a hardened
DACL only on a directory this call created), an existing parent is used
as it is, and a symlink or non-directory is refused. The lock file itself
is still created 0600 / owner-only on the file alone. CODEX_HOME keeps
using #8237's acquire_in_existing_dir, which never touched its mode.
…hed ocx-child artifacts
OPENCODEX_HOME= made the cache lookup join(, cache, ...), a path
relative to the server's working directory. An empty or blank value now
falls back to ~/.opencodex, as ocx-child does. structure/remote-link.md
also records that childKind joined the strict link record keys, so a
downgraded Home rejects a links.json that carries it (the same trade-off
as remotePlatform).
sync replaced the catalog backup with the new catalog before it wrote
models_cache.json. An I/O error or crash between the two left a cache of
previous-catalog entries next to a backup naming only the new catalog,
so the next reconcile kept those previous Home entries as local ones and
detach restored them into the native cache.
Before the cache write the backup now names the slugs of both catalogs;
after it, the new catalog alone. The regression interrupts a sync with
JournalWriteFault::AfterCatalogWrite and checks detach, directly and
after a retried sync.
test_hooks::barrier read two environment variables on every lifecycle
path and the env names were linked into the release binary. The barrier,
its env constants, and the env stripping for a spawned relay now exist
only with debug_assertions, the profile cargo test builds the binary
with; a release build compiles them to no-ops.
The guide claimed a bare SSH host works out of the box, but
resolveChildBinarySource only finds a build in OPENCODEX_CHILD_BIN_DIR,
native-bin/ sidecars (no package ships them), a source checkout's own
cargo release build, or a SHA256SUMS-verified
$OPENCODEX_HOME/cache/ocx-child/<version>/ (nothing fills it). A packaged
npm or desktop Home therefore reports plantable:false with
artifact_not_found.
The English guide and structure now list those sources in order, state
that packaged installs need one of them, and describe the Child's hash
tool requirement. When the probe reports artifact_not_found, the CLI,
the remote_plant_unavailable message (plantUnavailableGuidance), and the
#remote sheet (link.plant.artifactHelp in all 11 locales) name the file
and the directories Home reads.
FileLock checked the path with reject_symlink and then opened it with
create(true), so a symlink swapped in between made the open follow it
and create the link target. The open now uses O_NOFOLLOW on Unix, with
the value libc defines for each target, and FILE_FLAG_OPEN_REPARSE_POINT
on Windows, and refuses anything that is not a plain file. On Windows an
existing lock file is verified to carry the owner-only DACL instead of
being accepted unchecked. A debug-only barrier between the check and the
open lets the regression swap in the symlink.
The shutdown secret was a plain String in ChildStateV1, so every state
read, clone, and drop left a copy in memory and Debug printed it. It is
now a SecretString that is wiped on drop, serialized as the same plain
string, and redacted from Debug; load_live_creds no longer hands out a
copy nobody used, and the rollback records no longer wipe it by hand.
The daemon start line and the relay and lifecycle request heads that
carry the link token are built once at their final size into
SecretBytes, and state.json bytes are wiped after a read or write.
…cisely
The lifecycle reference said a second ocx sync fails fast on any Child.
That holds for a full ocx Child; on ocx-child only the --expect-link form
the Home's fan-out runs exits 5 with pending_operation, and a plain
ocx-child sync waits for the first apply. The structure note now names
who can act in the restore window, and the ocx-child status ledger no
longer carries stale test counts or a stale wp5 summary.
The e2e test built ocx-child with cargo but always looked for the binary under native/ocx-child/target, so a run with CARGO_TARGET_DIR set failed with ENOENT. It now resolves the target directory the way cargo does.
The attach success line named the link key identifier. Keep identifiers out of console output, matching the repository privacy rule; the regression asserts attach output never contains the key id.
Brings in #8237's commits after e459d86 (slug-owned models_cache sync and
detach, rollback restart commit ordering, control-mode exchange deadline,
bounded parity connect, no-follow lock opens with Windows DACL verification,
SecretString/SecretBytes, CARGO_TARGET_DIR-aware e2e, quieter attach).
Conflict: structure/remote-link.md, resolved as the union of both sides:
this layer's child.lock location, managed-path purge, and lock-parent
permission text, plus #8237's slug ownership, no-follow lock open, rollback
restart commit, and control-mode deadline text.
Semantic fix: #8237's no-follow lock test swapped a symlink in at
child/lifecycle.lock, which this layer replaced with
$OPENCODEX_HOME/child.lock; point it at the lock detach actually opens.
…cord exists
The enrollment-rollback purge deletes a planted ocx-child that cannot run
unless recovery evidence remains, but it only looked for child/state.json
and codex-journal.json. An attach interrupted before state.json exists
leaves only attach-rollback.json and the CODEX_HOME ownership record
(.ocx-child-owner.json); the purge then deleted the one binary that could
roll that attach back and reported success.
Both the POSIX and the Windows purge now treat the attach rollback snapshot
and the ownership record (under CODEX_HOME, defaulting to ~/.codex like
ocx-child) as recovery evidence, keep the binary, name the record on
stderr, and exit non-zero so Home reports a residual.
…sheet
DELETE /api/link/:id with { "purge": true } answers 409 purge_unsupported
when the Child turns out to run a full OpenCodex install, but the GUI had
no mapping for that code and showed the generic "could not be completed"
text. Map it to a message in all eleven locales that says there is no
planted binary to delete and to disconnect without deleting it.
The route-owner scrape now also reads the codes purgeDisconnectRemote
returns, because the DELETE route forwards them as a variable.

Review comments at @devlog/_plan/261107_ocx_child_plant_ux/000_roadmap.md:
- Line 88: Correct the `/api/link/issue` creation description in the roadmap:
state that client-initiated records omit `childKind`, rather than claiming it is
set to `"full"`. Keep the existing description of `link-enrollment.ts` and
hub-initiated `LinkRecord` creation unchanged.
Review comments at
@devlog/_plan/261107_ocx_child_plant_ux/030_wp3_cli_and_gui_remote_ux.md:
- Line 10: The capability registry and generated skill reference omit --plant
for link add. Update the registry and usage source so ocx capabilities --json
exposes the flag, while keeping src/cli/capabilities-base.ts untouched as
required by the diff; establish an allowed in-scope source for the registry
change, and regenerate the skill reference only if it is within writeScope.
Review comments at @docs-site/src/content/docs/guides/remote-link.md:
- Line 105: Update the lightweight Child detach instructions in the English and
Korean guides to use the installed executable’s recovery command for pre-placed
executables and Windows-managed paths, rather than assuming the POSIX cache path
exists. Preserve the existing `ocx disconnect` guidance and document the
appropriate installed-location and platform-specific command.
- Line 12: Update the Child requirements in the Japanese, Russian, and
Simplified Chinese remote-link guides to match the English exception: when Home
has a verified `ocx-child` build for the Child’s platform, it can install the
standalone binary on a bare SSH host without pre-installed OpenCodex, Node, or
Bun. Preserve each translation’s existing language and surrounding requirements.
- Line 12: Update the version requirement in the remote-link guide to
distinguish the minimum version for a full Child install or Child-initiated link
from the minimum Home version that supports planting `ocx-child` over SSH.
Verify the first Home release containing the planting command and state it
explicitly; if that release is not yet known, identify the required build by
feature rather than claiming Home 2.66.0 supports planting.
- Line 211: Update the `ocx link add` description to qualify rollback: state
that Home attempts to remove a newly planted binary after a conflict, but
cleanup may fail and require recovery on the Child. Do not imply rollback is
guaranteed or that Child files are always left untouched.
- Line 211: Update the `#remote` badge description to clarify that the Home
settings parity badge appears only after both Home and Child digests are
available; until then, a connected Child may show no parity badge.
- Line 200: Update the remote-link guidance around `ocx link add` to explain
that bare-host users must obtain the fingerprint from a trusted source before
running the non-interactive planting flow; clarify that interactive use displays
the offered fingerprint for approval.
Review comments at @docs-site/src/content/docs/ko/guides/remote-link.md:
- Line 86: Update the `ocx link revoke` usage syntax in the Korean guide to show
`--purge` and `--force --yes` as mutually exclusive alternatives, while keeping
`--json` optional; make the corresponding usage change in the CLI help so both
descriptions match.
Review comments at @gui/src/i18n/en.ts:
- Line 4357: Update the remoteLink.error.child_port_busy message in the English
and other locale catalogs to remove the hard-coded port number, so it does not
direct operators to free the wrong port.
Review comments at @gui/src/pages/RemoteLink.tsx:
- Line 137: Update linkActionError and the related error-view handling to
preserve residual and recovery state when rollback cannot purge a planted
binary, and show the existing localized cleanup guidance for that recovery
state. Ensure residual failures, including child_port_busy when cleanup remains,
do not display the inaccurate message that no Child files were modified or offer
retry as though nothing was changed.
- Around line 575-576: Update the alias-change handling around setAlias to clear
the current host probe and confirmation, and prevent in-flight probe or
confirmation responses for the previous alias from restoring either state.
Require a successful probe for the newly selected alias before enabling the
plant or connect action.
Review comments at @gui/src/pages/RemoteLinkDialogs.tsx:
- Line 44: Update the remote-link dialog’s purge-option visibility and selection
handling so Home-initiated links with an unknown child kind can offer purge and
forward the user’s selection through RemoteLink. Preserve existing behavior for
known kinds and rely on the backend’s Child inspection when purging.
- Around line 29-30: Update the force-removal guidance associated with
`forceCmd` in the `isEphemeral` flow so it does not assume every Child uses the
POSIX cache path. Show platform-specific guidance that explains how to locate a
pre-placed executable and how to address the still-attached Child configuration
and running relay after force removal.
- Line 30: Update the ephemeral recovery messages in the CLI enrollment rollback
and forced-revoke flows to give Windows operators the PowerShell detach command
for the planting path, including the USERPROFILE fallback when LOCALAPPDATA was
unset, while retaining the POSIX instructions. Update the corresponding
recovery-message assertion in the force-link test to match.
Review comments at @gui/src/pages/RemoteLinkSheet.tsx:
- Line 137: Update the localized `link.setup.requirements` text to reflect that
the Child may be bare and Windows x64 is supported alongside the existing
platforms. Describe the prerequisites for the planting flow, and keep the
requirements consistent across all locales.
- Around line 79-85: Update the unavailable-build guidance in the
RemoteLinkSheet flow to handle `plantUnavailableReason === "checksum_mismatch"`
with localized instructions covering manifest, symlink, and permission
requirements, and telling the operator to test the connection and confirm the
host again after repair. Preserve the existing `artifact_not_found` guidance and
generic unavailable message.
- Around line 83-85: Update the link.plant.artifactHelp translation in all
locales to instruct users to install the artifact, click Test connection, verify
the fingerprint, and then confirm the host. Keep the existing artifact filename
interpolation used by RemoteLinkSheet.
Review comments at @native/ocx-child/src/cli.rs:
- Around line 1678-1682: The detach flow releases `lock` before
`purge_after_detach`, allowing an attach to complete before purge removes the
executable. Add a shared ownership fence that coordinates purge with attachment
on both detach paths, and ensure purge proceeds only when no newly attached link
owns the executable.
- Around line 1675-1677: Keep the startup gate file outside the removable child
directory so foreground relays and new starts synchronize on the same gate. In
the foreground relay startup flow, recheck the captured attachment identity
immediately before binding and reject stale starts; preserve the existing
cleanup behavior for the removable directory.
Review comments at @native/ocx-child/src/platform.rs:
- Around line 1405-1417: Check the `Command::new("cmd.exe")` spawn result before
returning `PurgeExecutableOutcome::Removed`; if launch fails, return an error
that identifies the retained `trashed` file instead of reporting successful
removal. Preserve the existing success outcome when the helper starts
successfully.
Review comments at @native/ocx-child/src/state.rs:
- Line 33: Add legacy lifecycle-lock retirement to the Child detach flow so an
upgraded Child can remove the stale child/lifecycle.lock without allowing older
processes to use that lock during removal. Preserve the existing lock safety
guarantees, and add a test covering detach of an upgraded Child with the legacy
lock present.
Review comments at @src/cli/link-enrollment.ts:
- Around line 206-207: Update the conflict handling around the child_port_busy
and child_external_provider_conflict checks to handle residual: true before
throwing either conflict-specific error. When rollback purge fails, include
fixed recovery guidance with detach --purge for a newly planted binary, and do
not claim that no Child files were modified.
Review comments at @src/link/child-binary-source.ts:
- Around line 70-74: Update the artifact validation flow around isSafeDirectory
so a writable artifact directory cannot establish its own binary’s trust through
a co-located SHA256SUMS file. Authenticate artifacts against a trusted digest or
signature, or establish race-safe trust for the directory and its ancestors
before accepting or executing them.
Review comments at @src/link/remote-plant.ts:
- Around line 193-198: Update the POSIX `recovery_pending()` scan to include
`child/link-key` and `child/last-catalog.json`, and add the corresponding files
to the Windows recovery scan. Ensure rollback reports a residual and keeps the
planted binary when either orphaned file remains; cover both cases in the
rollback tests.
- Around line 272-273: Before accepting a `NotAttached` result with `purged:
true` in the `childKind` handling path, verify that the current Child is still
the ephemeral runtime associated with the same link. Reuse the established
runtime and link identity checks; if the Child has been replaced by a full
runtime, do not revoke the link based on the stale `childKind` value.
- Around line 59-64: Align the inspection and enrollment PATH resolvers so both
apply the same candidate check when selecting an `ocx` executable, including
when it exits successfully without version output. Add a regression test
confirming that inspection and enrollment select the same PATH-only `ocx-child`
in this case.
Review comments at @src/link/remote-windows.ts:
- Around line 186-188: Update the promotion sequence around [OcxJob]::Run so the
temporary binary is verified before replacing $dst, then promote it with an
atomic same-directory replacement rather than [IO.File]::Copy. Preserve cleanup
and failure handling for the temporary file and destination.
Review comments at @src/link/status-projection.ts:
- Line 144: In the status projection, stop including record.childKind by default
and include it only when a separate status opt-in is present. Update the current
CLI and dashboard to request that opt-in, while preserving the existing
compatibility and diagnostics flags and ensuring older clients that omit it
receive responses without childKind.
Review comments at @src/server/management/link-enrollment.ts:
- Around line 257-265: Coordinate the remote planting flow in the `body.plant`
branch with the Child lifecycle so concurrent enrollments cannot replace a
binary while another Home is using it. Track whether this attempt created the
link, and restrict rollback detachment to that link; preserve any link owned by
another Home.
- Around line 267-278: Update the plantErr catch in the remote planting flow to
report an uncertain or residual outcome for SSH transport failures, with
platform-specific inspection and removal guidance; do not imply the remote
operation stopped. Preserve the existing timeout handling and establish which
errors indicate transport failure before applying the uncertain status.
Review comments at @src/server/management/link-routes.ts:
- Around line 215-216: Reject requests with purge enabled for client-initiated
links before any link stopping or revocation occurs, and return an error
explaining that Home cannot purge this direction. Locate the validation in the
route handling the `force` and `purge` payload flags, preserving existing
behavior for other requests.
- Around line 233-238: Update the `purge` flow around `purgeDisconnectRemote` so
a retry can resume Home cleanup after a successful purge when key revocation or
link-store removal previously failed. Accept a missing managed executable only
when a verified cleanup receipt establishes that purge already completed;
otherwise preserve the current failure behavior and do not treat a missing
executable alone as success.
Review comments at @structure/remote-link.md:
- Line 191: Update the remote planting contract around
remotePurgePlantedChildArgv to state that purge is attempted only when planting
returns success; also document that an SSH timeout after the POSIX atomic move
may leave the binary installed without a purge attempt or residual warning, so
the outcome is uncertain.
Review comments at @tests/clients/link-child-plant-foundations.test.ts:
- Line 49: Add a persisted record with childKind set to "full" to the test using
readLinkStore, then assert the loaded record retains "full". Preserve the
existing ephemeral and omitted-childKind cases and invalid-value checks.
- Around line 334-336: Replace the string-only checks around the generated purge
script with a Windows test that executes it using isolated homes. For each
recovery-record case, assert a nonzero exit and that the binary remains; with no
recovery record, assert a successful exit and deletion. Reuse the test’s
existing script-generation flow and avoid relying on platform-specific behavior
outside Windows.

Allow purge for unknown-kind Home-initiated links.
Legacy lightweight links omit childKind, so the dialog hides the purge option and RemoteLink.tsx:424 would discard it. Users cannot delete the planted binary through the dashboard. Offer purge for these links and forward the selection; the backend already inspects the Child before purging.

In the status projection, stop including record.childKind by default and include
it only when a separate status opt-in is present. Update the current CLI and
dashboard to request that opt-in, while preserving the existing compatibility
and diagnostics flags and ensuring older clients that omit it receive responses
without childKind.

Fence planting and rollback by Child lifecycle ownership.
If two Homes confirm the same bare account, the second can overwrite the first Home’s binary after enrollment. Its preflight then rejects the connected Child, but rollback detaches the first Home’s link. Coordinate planting with the Child lifecycle and detach only a link created by this attempt.

Coordinate the remote planting flow in the `body.plant` branch with the Child
lifecycle so concurrent enrollments cannot replace a binary while another Home
is using it. Track whether this attempt created the link, and restrict rollback
detachment to that link; preserve any link owned by another Home.

Make a completed purge recoverable on retry.
If key revocation or link-store removal fails after a successful purge, retrying purge: true fails because the managed executable is gone. On a bare Child, the operator must force removal or restore an executable. Use a verified cleanup receipt to resume Home cleanup without treating every missing executable as a successful purge.

- OpenCodex 2.66.0 or later is installed on the Child computer, and on Home for a Child-initiated link.
- OpenCodex 2.66.0 or later on Home (and on the Child for a Child-initiated link or full Child install). When adding a Child from Home, a bare SSH host needs no pre-installed Node, Bun, or OpenCodex if Home has a verified `ocx-child` build for the Child's platform: Home can then plant that standalone binary over SSH during onboarding. The npm package and the desktop app do not include `ocx-child` builds; see [Ephemeral Child machines](#ephemeral-child-machines-ocx-child) for where Home looks for one.
The Japanese, Russian, and Simplified Chinese guides each require OpenCodex on every Child. If Home has a verified matching ocx-child build, it can instead plant the binary on a bare host. Update line 12 in each translated guide to describe that exception.

For disposable SSH devboxes, containers and lightweight cloud VMs where installing the full Bun OpenCodex runtime is unnecessary, place the standalone Rust `ocx-child` binary (`cargo build --release --locked --manifest-path native/ocx-child/Cargo.toml`) in `~/.local/bin/ocx-child`, `~/.cache/opencodex/bin/ocx-child` (or `%LOCALAPPDATA%\opencodex\bin\ocx-child.exe` on Windows) or on `PATH`. Before enrollment, Home probes every full `ocx` candidate first and falls back to `ocx-child` when no runnable full `ocx` is present; once `$OPENCODEX_HOME/child/state.json` exists, remote commands keep targeting `ocx-child` until it detaches.
For disposable SSH devboxes, containers and lightweight cloud VMs where installing the full Bun OpenCodex runtime is unnecessary, Home can stream a SHA-256-verified standalone `ocx-child` binary (no Node or Bun required on the Child) over SSH `stdin` into `~/.cache/opencodex/bin/ocx-child` (`%LOCALAPPDATA%\opencodex\bin\ocx-child.exe` on Windows) when you choose **Plant lightweight agent & connect** in `#remote` or run `ocx link add <alias> --plant --expect-fingerprint SHA256:…` (an interactive `ocx link add <alias>` asks once before planting). The Child downloads nothing, so it needs no outbound internet access, but a POSIX Child must have `sha256sum`, `shasum`, or `openssl`: the binary is checked against its SHA-256 before it is installed or run, and without one of those tools the plant is refused (`hash_tool_unavailable`). You can also pre-place `ocx-child` in `~/.local/bin/ocx-child`, `~/.cache/opencodex/bin/ocx-child`, or `PATH`. Before enrollment, Home probes every full `ocx` candidate first and falls back to `ocx-child` when no runnable full `ocx` is present; once `$OPENCODEX_HOME/child/state.json` exists, remote commands keep targeting `ocx-child` until it detaches.
For a bare host, the ocx link probe step at line 194 fails before it prints the fingerprint. Document obtaining the fingerprint from a trusted source for --plant --expect-fingerprint. For interactive use, ocx link add displays the offered fingerprint before asking for approval.

`native/ocx-child/Cargo.toml` and `native/ocx-child/src/lib.rs` build a standalone lightweight Rust binary (`ocx-child`) for disposable SSH devboxes, containers and VMs that do not run a persistent Bun OpenCodex install. Remote candidate discovery in `src/link/ssh-argv.ts` and `src/link/remote-windows.ts` tries `ocx-child` first when `$OPENCODEX_HOME/child/state.json` is present (preserving an active `ocx-child` enrollment even if full `ocx` is installed later), and otherwise tries every full `ocx` path before falling back to `ocx-child` in `~/.local/bin`, `~/.cache/opencodex/bin` (plus `%LOCALAPPDATA%\opencodex\bin` on Windows) and `PATH`, keeping Windows encoded PowerShell below `POWERSHELL_ENCODED_MAX` (`8000`).
When detached, `ocx-child config show --json` reports `{"port": <listenPort>, "runtimeRole": "standalone", "ephemeralChild": true}`, recognized by `isDetachedEphemeralChildConfig` in `src/link/ephemeral-child.ts`. During `POST /api/link/apply`, `src/server/management/link-enrollment.ts` accepts that clean detached state without a pre-running standalone daemon, refuses `409 child_restart_unsupported` before key issuance if the `/healthz` HTTP probe returns `200` on `<listenPort>` (`502 child_preflight_failed` on an SSH transport drop; non-200 foreign listeners are rejected by `ocx-child connect`'s `TcpListener::bind` port check and compensated by Home), enrolls through `connect --link --key-stdin`, starts `ocx-child serve` via `restart`, and verifies `role: "client"` `/healthz` plus an authenticated `/v1/catalog` callback.
When `allowMissing: true` is passed to `POST /api/link/probe` (with `includeVersion: true`) or `POST /api/link/confirm-host`, `src/link/remote-plant.ts` inspects the remote target triple (`darwin-arm64`, `darwin-x64`, `linux-x64`, `linux-arm64`, `windows-x64`) and classifies `runtimeKind` as `"full"`, `"ephemeral"`, or `"missing"`, while `src/link/child-binary-source.ts` resolves a non-symlink `ocx-child` artifact (`OPENCODEX_CHILD_BIN_DIR`, `native-bin/` sidecars next to the sources or the executable, host-matching local Cargo release builds of `native/ocx-child` in a source checkout, or `SHA256SUMS`-verified `$OPENCODEX_HOME/cache/ocx-child/<version>/`; an empty `OPENCODEX_HOME` counts as unset). No package ships `native-bin/` sidecars and nothing populates the cache, so a packaged npm or desktop Home answers `plantable: false` with `plantUnavailableReason: "artifact_not_found"` until an operator provides a build; the CLI, the `remote_plant_unavailable` message (`plantUnavailableGuidance`) and the `#remote` sheet name those locations. On a bare host (`runtimeKind: "missing"`), `POST /api/link/apply` requires explicit `plant: true`, streams the verified binary over SSH `stdin` into `$HOME/.cache/opencodex/bin/ocx-child` (`0700` atomic write on POSIX, only after the size and the SHA-256 match; the digest is checked with `sha256sum`, `shasum` or `openssl dgst`, and with none of them the plant exits before installing or running anything and Home answers `502 remote_plant_failed` with hint `hash_tool_unavailable`) or `%LOCALAPPDATA%\opencodex\bin\ocx-child.exe` (inside `OcxJob` on Windows, refusing symlinks and reparse points), and purges any freshly planted binary via `remotePurgePlantedChildArgv` if enrollment fails. When the planted binary cannot run, that purge deletes it only if no recovery record remains (`$OPENCODEX_HOME/child/state.json`, `codex-journal.json`, `attach-rollback.json`, or `$CODEX_HOME/.ocx-child-owner.json`); otherwise it keeps the binary so `detach` can finish, names the record on stderr, and exits non-zero, and Home answers with `residual: true` and the `detach --purge` recovery step.

Document the uncertain plant-timeout outcome.
If SSH times out after the POSIX mv, the binary can remain without a purge attempt or residual warning. Update structure/remote-link.md:191 to limit the purge statement to plants that returned success and describe this timeout outcome.
As per coding guidelines, “A doc in this folder states the contract that holds right now.”

Review comment at @structure/remote-link.md at line 191:
Update the remote planting contract around remotePurgePlantedChildArgv to state
that purge is attempted only when planting returns success; also document that
an SSH timeout after the POSIX atomic move may leave the binary installed
without a purge attempt or residual warning, so the outcome is uncertain.

Add a full-install record to the persistence test.
The test writes only ephemeral and legacy records. Add a full record and assert that readLinkStore returns "full". The current test can pass if the parser rejects or drops that value.

Add a persisted record with childKind set to "full" to the test using
readLinkStore, then assert the loaded record retains "full". Preserve the
existing ephemeral and omitted-childKind cases and invalid-value checks.

Test the Windows recovery gate by executing the purge script.
In tests/clients/link-child-plant-foundations.test.ts:328-336, the assertions can pass even if purge deletes an unrunnable binary when a recovery record exists.
Add a Windows test that runs the generated PowerShell with isolated homes. For each recovery record, assert a nonzero exit and that the binary remains. With no record, assert a successful exit and deletion.

Replace the string-only checks around the generated purge script with a Windows
test that executes it using isolated homes. For each recovery-record case,
assert a nonzero exit and that the binary remains; with no recovery record,
assert a successful exit and deletion. Reuse the test’s existing
script-generation flow and avoid relying on platform-specific behavior outside
Windows.
