Reviewed exact head fee5ee2d65e0b4a9a4f43f619c90c587e9440fcd. The regression passes by deriving heartbeat names from the already-incomplete reconnect inventory, which drops the live heartbeat-only-worker; it does not add that live/adopted worker to the authoritative inventory. In the measured #1602 incident, inventory omission was the defect and heartbeat was the independent live truth, so this change can leave attach broken while making both payloads consistently wrong. Require the live/adopted worker, with preserved/adopted immutable identity, to appear in both inventory.sync and heartbeat after repair/reconnect, or prove the independent worker was stale. Preserve multi-node mismatch guards. Fleet E2E remains skipped and the hosted-backend confirmation attempt is not a pass. No merge/runtime/remote-row action performed.

Exact-head review of 4a695b26e9022756f1729be31b929fa61535b0a4: the prior blocker remains.
The new assertions describe the desired final set, but they do not exercise the production path that failed:
- the runtime test manually constructs
LiveFleetInventoryCandidate; it bypassesWorkerRegistry::live_fleet_inventory_candidates(), including theparent.is_none()exclusion and real process-liveness/adoption state; - the node-control test manually sends an already-repaired
UpdateInventory; it does not connect the live registry throughreconcile_fleet_inventory_with_live_workers()to inventory and heartbeat; - no production repair changed in this amendment. The existing reconciler landed in #1555 before the measured #1602 incident, yet the live local PTYs remained absent through repeated syncs. Deriving heartbeat from the still-incomplete inventory therefore can still hide them.
Required before approval: add a production-path regression built from an actual live/adopted WorkerRegistry handle/generation that begins absent from fleet_inventory, passes candidate selection, resolves/preserves the immutable Relaycast identity under the real supported credential configuration, publishes the repaired inventory, and is then present in both initial/reconnect inventory.sync and heartbeat. If existing production logic truly already achieves that, the integrated regression must demonstrate it and explain why the deployed incident escaped it (for example candidate parent/adoption filtering or unavailable HTTP lookup). Otherwise amend the production repair without weakening workspace/provider and immutable-ID guards.
The hand-written repaired vector is a useful downstream arm but is not evidence that the missing live PTY enters that vector. CI running on this head does not resolve the gap. No merge/runtime/remote action performed.

The landed process-tree contract test's 100 ms trigger repeatedly killed Node before it printed the descendant PID on this host; this branch raises only that startup budget to 500 ms, preserving the process-group cleanup assertion. The full 45-test contract suite passes.
