fix(cli): preserve default bind identity for guarded stops - #8221
A desktop-approved stop could refuse an otherwise verified default-bind runtime because its legacy runtime record omitted the hostname. Preserve that absence, accept it only for the approved default loopback, and publish the actual bound hostname for new records. Present hostnames remain exact, so wildcard and loopback binds stay distinct.
Keep update restart compatible with the default bind by freezing diagnosed configuration, validating the child handoff before stop, and checking the replacement's bind and attestation. This extends the carry into src/cli/update-restart* and src/cli/system-restart-client.ts because those paths consume the same runtime record.
Refuse a present empty or whitespace-only runtime hostname before an update restart can stop the process; only an absent legacy hostname receives the default-loopback compatibility treatment.
Explain the refusal with a fixed, non-sensitive reason and a safety-qualified recovery path that requires independently checking ownership, supervisor and listener state before stopping or starting.
bun run typecheck — passed on Windows at afef9965f965c79af6acec520eb784c39902522c after rebase onto b19daa42a81632cfc5fd3ceb1f0c1647d7e51e29.

The composed blank-host tests cover attestation, candidate handoff, fixed output and refusal before stop.
At the preceding head, bun test tests/cli/cli-update-restart-transport.test.ts passed 44/0 both alone on that head and alone on its clean base fc6997df57800d17d2154c3aabfa79e02c2bafd1; a batch timeout was not reproduced alone and was classified as shared-host timeout noise. The batch now passes at a3199c79.
bun run test:changed — 1,007 passed, 8 skipped, 0 failed across 35 files on Windows at afef9965.
bun run structure:check — passed at afef9965.
bun test tests/ci-workflows/file-size-ratchet.test.ts — 9 passed before rebase; rebase touched no capped file in this change.
cd docs-site && bun install --frozen-lockfile && bun run build — passed at afef9965, 641 pages built; Vite and Astro emitted warnings.
The initial test:changed failed eight Desktop supervision cases due to a fixture missing the new handoff fields. bun test tests/cli/cli-restart-health.test.ts passed 54/0 on the corrected head and independently passed 54/0 on clean origin/dev at 708cd065ef1851fe6c3e0412f91f5d4b6714faa7; the fixture was fixed before push.
The full suite was not run locally because six lanes were running concurrently. CI covers the broader Ubuntu suite and POSIX launcher cases via ci:full; a complete POSIX update-restart end-to-end run was not performed.

Summary by CodeRabbit
Bug Fixes
Guarded stops accept older runtime records without a hostname only when the approved target uses the default loopback address. Mismatched hostnames, including wildcard-versus-loopback differences, are still refused.
Update restarts verify hostname and configuration consistency before stopping the current proxy or accepting its replacement. Requests are rejected if the update configuration changes during discovery.
New runtime records report the hostname used by the bound server. Restart attempts with a blank runtime hostname are refused with guidance to verify the process and listening address.
Documentation
Clarified hostname checks for older runtime records, loopback addresses, and wildcard binds, and added restart recovery guidance.
Runtime records now retain the listener’s bound hostname, and tracked-runtime inspection preserves a missing hostname as undefined. Guarded stops apply explicit approval rules to missing and present hostnames. Update restarts capture and validate hostname state, reject blank runtime hostnames, and verify replacement runtime records.
Changes: Runtime hostname handling
Layer / File(s)
Summary
Runtime records and guarded stop src/cli/index.ts, src/config/tracked-runtime-inspection.ts, src/cli/stop-approval.ts, tests/cli/cli-stop-json.test.ts, tests/service/process-state.test.ts, tests/service/shutdown-launcher.test.ts, docs-site/src/content/docs/reference/cli/lifecycle.md, structure/config.md, structure/runtime.md
Runtime records store the bound server hostname. Tracked-runtime inspection preserves an omitted hostname as undefined. Guarded-stop approval accepts an omitted hostname only for an approved 127.0.0.1 target; a present hostname must match exactly. Tests and documentation cover these rules.
Capture and validate the restart handoff src/cli/update-restart-home.ts, src/cli/update-restart-child.ts, src/cli/update-restart.ts, src/cli/system-restart-client.ts, src/cli/index.ts, tests/cli/cli-restart-health.test.ts, tests/cli/cli-update-restart-admission.test.ts, tests/cli/cli-update-restart-child.test.ts, tests/cli/cli-update-restart-home.test.ts, tests/cli/cli-update-restart.test.ts, tests/cli/system-restart-client.test.ts, structure/ops/service-and-sidecars.md, docs-site/src/content/docs/reference/cli/lifecycle.md, docs-site/src/content/docs/zh-tw/reference/cli/lifecycle.md
Home snapshots include the diagnosed hostname, and marker parsing validates bind-host forms. Restart checks accept an omitted configured hostname only for default loopback, reject blank runtime hostnames before stop, and detect changed home snapshots. Tests and documentation cover hostname validation, configuration drift, restart behavior, and recovery guidance.
Verify the replacement runtime src/cli/update-restart.ts, tests/cli/cli-update-restart.test.ts
Replacement verification checks the child PID, runtime record PID and port, normalized hostname, sibling-port status, and attestation. It then requires an exact runtime-record reread. Tests cover accepted and rejected replacement cases.

Checked head: 7af5899 (lane head af85e24 + merge of dev 553a621 for the 5-shard workflow; remerge-diff showed no manual resolution); all 34 PR checks passed (desktop shell rerun after a 45-minute job-limit cancellation); no unresolved review threads.
Review: carry of fix(stop): read an absent tracked-record hostname as unknown, and persist the bound scope #8182 — an absent tracked-record hostname is read as unknown instead of loopback; the same runtime record consumers (update-restart, system-restart-client) refuse an explicit blank hostname before stop with specific recovery guidance; zh-TW lifecycle docs corrected. Fresh independent correctness/security review PASS on the source head; a claimed localhost regression was withdrawn as pre-existing on base.
