fix(link): recover Home-initiated links after outages and make Retry reconnect (carry #6900) - #6915

Conversation
The Home ran its link tunnels without a retry policy, so a failed link stayed failed until a proxy restart. A retry that came back up was also promoted only by a catalog request from the Child, so an idle Child's healthy reconnect was killed at the five-minute outage limit: one network blip took the link down for good. - run the Home supervisor with HOME_TUNNEL_RETRY_POLICY, the same cadence as the Child's own tunnel (timeout/forward 60 s, auth 5 min, host key never) - promote a retry whose ssh child outlives a 15 s grace, longer than ssh's ConnectTimeout, as five seconds already promotes a first attempt - keep a retry running while the state reads failed, and let a retry that started just before the outage limit finish its grace - spawn on reload only for a fresh link or a due attempt - report an exit even when its stderr cannot be read - document the Home policy in structure/remote-link.md and the Remote Link guide (all locales) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A retry whose grace ended on the tick that reached FAILED_AFTER_MS, or one still running when a tick arrived late after a sleep, was first reduced to failed and then killed instead of promoted. Check promotion before the tick so a child that has outlived its grace is kept. Addresses the Codex review on #6900. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The exit handler drops the child before it awaits stderr. A tick in that window could fail the link on the outage clock with a one-minute retryAt, and the host-key exit that followed was then ignored, so a changed host key was retried. Skip the tick while an exit is still being classified. Addresses the second Codex review on #6900. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
In the failed state the dashboard's Retry only re-read /api/link/status,
so a link the supervisor had given up on stayed failed until a proxy
restart. Retry now restarts the tunnel of each failed or reconnecting
Home-initiated link, without restarting OpenCodex.
- LinkSupervisor.reconnect(linkId): wait for a running reload, stop the
link's child, forget its backoff or failed state and spawn a fresh attempt
- POST /api/link/{id}/reconnect for a dashboard session or the loopback
admin token; a Child-initiated link is refused (409
link_not_home_initiated) because the Child owns that tunnel
- ocx link reconnect --link-id <id> [--json]
- an exit that finishes after a reconnect started a fresh child no longer
overwrites the new attempt's state
- docs: Remote Link guide (all locales), structure docs, generated ocx
skill surface

ConnectTimeout covers the TCP connect, the SSH handshake and key exchange; authentication and the remote forward request come after it. Say so in the supervisor comment and structure/remote-link.md, and record that liveness promotion is the same heuristic the first attempt uses. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…nnect on the listener
- every spawn bumps a per-link generation; an exit still classifying its
stderr, or a stop still waiting for its child, applies only while its
generation is current, so a reconnect's new child keeps its own state
- the draining marker records its generation and is cleared by a newer spawn
- overlapping reconnects for one link share one restart
- POST /api/link/{id}/reconnect requires the link listener to be listening
(503 listener_unavailable), as apply does, before it starts a forward
- structure/remote-link.md lists ocx link reconnect in the CLI inventory
Addresses the CodeRabbit and Codex reviews of c0a377a on #6900.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Run reconnect, reload, stopLink and shutdown through one per-supervisor lifecycle queue. After the old child exits, re-resolve the current record and listener ownership, so a link removed, changed or made client-owned during the wait is never respawned (review R1, R1b, R1c; Codex P2). - DELETE holds its link through child stop, remote disconnect, key revocation and store removal, then reloads the supervisor store before releasing the hold. - Global stop now waits for a reconnect's draining child (review R2). - Retry stays disabled until the status refresh after reconnect completes (Codex P2).

📝 Walkthrough
Merge Risk: 🔵 Low · up to Home links now recover automatically, and Retry reconnects them. In two edge cases recovery can stall: Retry stops after the first link that fails to reconnect, and a link whose SSH error output never finishes stops retrying. Both are small follow-ups and are not merge-blocking. Pre-merge checks |

the reconnect loop after an individual request fails, then report the first
error after all rows have been attempted. Preserve the existing refreshStatus
and busy-state cleanup behavior.
Review comments at @src/link/supervisor.ts:
- Around line 260-270: Update the exit handling around `SshChild.stderr` so
stderr classification cannot hold up supervisor ticks after the SSH process
exits. Ensure the bounded path retains already-consumed stderr and preserves
host-key and authentication classifications; do not substitute an empty string
when stderr is still pending.

…ement ingress (carry #6892) (#6913) * fix: restore remote hub browser pairing Carry of #6892 onto dev (the original targets main and is 26 commits behind dev). Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * fix(link): preserve loopback management access and harden pairing recovery - Resolve a loopback Host before the marked hub-management public-origin check, so ocx gui and local CLI calls to 127.0.0.1:<management port> keep working (Codex P1, review S1-01). - Offer pairing recovery only for 401/403 status failures, not offline, 5xx or malformed responses. - Move focus into the manual pairing form when recovery opens it. - Thread the pairing AbortController through session validation so an unmounted form cannot apply stale App state. - Translate the new pairing errors in every locale and update the owning structure docs. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * docs(structure): scope the management-listener pairing guarantee to what the runtime enforces Independent security review S2-02: the public listener with authentication on still redeems a grant presented with the canonical public Host/Origin, unchanged from dev. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * docs(structure): keep the pairing recovery note in its own paragraph Avoids an adjacent-line conflict with #6915's dashboard route list update; content unchanged. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * fix(gui): retain pairing validation retries and roll back rejected sessions Keep the consumed grant out of retry submissions and validate the installed candidate without automatic session renewal or admin-token fallback. Use an opaque in-memory handoff to restore the previous shared session on definitive rejection or cancellation while preserving newer logins. Cover transient retries, 401/403 rollback, cancellation, and App recovery. Add retry copy to all locales and document the handoff contract. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * fix(gui): preserve pairing rollback ownership after background 401 Carry opaque handoff ownership through automatic session invalidation so validation rejection and cancellation still restore the previous session. Keep newer login, explicit logout, and target replacement authoritative. Add concurrent recovery and supersession regressions, including malformed bootstrap recovery and Cloudflare challenge retry. Qualify the remote hub and structure documentation around definitive rejection and restoration. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * fix(gui): discard session recovery from superseded generations Bind recovery to the runtime and session generation that started it. Check that revision after bootstrap headers and body, before credential changes and admin-token fallback, and before authenticated retry and invalidation. Rollback, login, logout, and target replacement supersede older recovery; unchanged target refreshes retain current recovery and shared resolution. Cover deferred headers/body with valid and malformed HTML across rejection, cancellation, newer login, logout, target round trips, and current recovery. Document the scoped recovery and rollback guarantees. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * fix(gui): preserve explicit session authority across pairing and recovery Block automatic invalidation and recovery during and after logout until an explicit login or target replacement supersedes it. Track overlapping logout requests so a successful logout remains authoritative even if another fails. Capture the pairing revision before sending the exchange and attach handoff ownership before synchronous session events. Superseded exchanges cannot install credentials after delayed headers or body completion. Keep watchdog write cancellation separate from current-request notification so timeouts still report an unavailable session without admitting late writes. Cover deferred exchanges, both logout/recovery response orders, explicit login, overlapping logout, reentrant session events and watchdog ordering. Synchronize the pairing and recovery contracts in both documentation surfaces. Co-authored-by: Bướm Em <91105424+BuomEm@users.noreply.github.com> * fix(gui): guard discovery bootstrap and bound pairing requests Route App discovery bootstrap through automatic recovery authority captured before fetching, so delayed headers or bodies cannot supersede logout or a newer session. Share a deadline helper across bootstrap and pairing that also settles signal-dropping transports. Bound pairing exchange and validation through body consumption, preserve validation retry ownership on timeout, and roll back an unreturned exchange handoff on lifecycle cancellation. Cover App discovery/recovery/logout ordering, delayed valid and malformed bootstrap HTML, stalled exchange and validation headers/body, deadline fallbacks and cancellation. Synchronize the documented contracts.

Summary
Carry of #6900 by @WOULDU-pres onto
dev. The six original commits are preserved with their author. Maintainers could not push the review fixes to the fork branch, so they are added here.A Home-initiated Remote Link (the Home's
ssh -Rtunnel) never recovered after a network drop (#6899). A reconnect that came up while the link wasreconnectingwas killed five minutes later asfailed: timeout. On the Home,failedwas terminal, and the dashboard's Retry only re-read status.The original commits do four things:
Review fixes on top:
The host-key failure stays terminal and the auth retry bound is unchanged.
Closes #6899
