ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR spans relay persistence and cleanup semantics, a new status contract, and web/mobile presentation. Its durable marker and altered handling of an externally deleted tunnel create production runtime and user-facing behavior that warrants human review.

Once cleanup removes a legacy host's tunnel, an older web- or mobile-linked host stays offline until it updates. The relay only reported "offline", so the user had no way to know an update was the fix. Record on the allocation when cleanup deletes its tunnel, cleared when any tunnel is recorded again. The status response carries an optional offlineReason of "tunnel_released" for that case. Web and mobile show a message asking the user to update T3 Code on that computer. Older clients ignore the field. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
release also handles a host shutting down and recoverable cleanup. Both leave hosts that get a new tunnel on their own, but every release marked the allocation, so status could tell those users to update T3 Code. The reaper now asks for the marker only when it deletes a legacy host's tunnel. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
When Cloudflare applied a delete but its response timed out, the release rolled back, including the released marker. No later sweep can find a deleted tunnel to retry, so the host showed offline with no explanation. On a failed delete, check whether the tunnel still exists; if it is gone, commit the release.

Once #13565 removes a legacy host's tunnel, an older web- or mobile-linked host stays offline until it's updated. The relay only said "offline", so the user couldn't know an update was the fix.
Relay:
tunnel_released_atallocation column is set by the claim that deletes the tunnel, and cleared whenever a tunnel is recorded again. The migration was generated with drizzle-kit, chained aftermanaged_endpoint_recovery; it only adds that column.offlineReason: "tunnel_released".Clients: a shared message in
client-runtime, "Offline for a while, so its T3 Connect tunnel was removed. Start T3 Code on that computer and update it to the latest version to reconnect." It's shown in the web T3 Connect list (row text and dot tooltip) and on mobile in place of the raw relay error. Older clients ignore the new field.docs/user/remote-access.mdgets one paragraph on this.Verification: relay, contracts, client-runtime, web and mobile all typecheck. Tests: relay 158, web 16, mobile 27, client-runtime 37. New tests cover:
Not verified: how it looks in a real client. No screenshots.
Stack 5/6. Merging deploys the migration (one nullable column).
