admin b505ce4ba0 hub v0.159.0 (R-1154, after security review): the enroll reuse path re-issues nothing, it warns the operator
The first draft (5121536f, unpushed) re-issued the claim code and the off-site login on a
reuse whose old box was stale or switched off. A security review flagged it: the caller
holds only the household's retrieval passphrase, and both re-issues are operator
session-only actions (05 section 17.5, 09 decision 252, R-1055/R-1059). Now the reuse
path classifies the old box and re-issues nothing: gone -> host_reinstall_over_old_host
(warning, mailed to the operator: delete the old host and re-run, or re-issue by hand);
live -> host_reenroll_while_live (info). The mint path after the operator's delete is
unchanged and still re-issues. The once-per-silence record and the claim engine comment
edit are reverted. 05 section 8, README and CHANGELOG updated; tests red-proved.

// R-1154 (hub v0.159.0, brief 2026-10-19) — a reinstall while the customer's OLD host record still exists.
//
// POST /host-enroll is called by the installer (felhom-host-install.sh step 4) on EVERY pass, a --resume
// included, with the customer's retrieval passphrase. An existing host record is reused (same host id and
// key — a reinstalled box takes over the record). The clean-slate re-issues (reissueOnReenroll: a new claim
// code mailed to the household, the off-site provider password reset) run ONLY on the mint path, i.e. after
// the OPERATOR deleted the old host. Until v0.159.0 a reinstall that kept the old record skipped them IN
// SILENCE (demo-hp 2026-08-21; Tester4's standing reinstalls).
//
// THE RULE: the reuse path NEVER re-issues anything; it makes the reinstall LOUD instead.
//
// - The old box looks gone (no controller wait connection open now, AND either the household switched it
// off on purpose — deliberate_off_at inside its hold — or BOTH the agent's host report and the
// controller's report are older than staleThreshold or absent; the hostStatus threshold and comparison):
// the operator-only WARNING host_reinstall_over_old_host, mailed to the operator, saying what to do.
// - The box is live (a --resume after its agent started, a repair re-run, or a reinstall done within the
// threshold of the old box's last report): the operator-only INFO host_reenroll_while_live, recorded on
// the event list, never mailed.
//
// WHY NOT RE-ISSUE AUTOMATICALLY (security review of the first draft, 2026-10-19): the passphrase is a
// household-held secret typed into the installer. Re-issuing a household's off-site credential and
// (re)sending its claim code are operator SESSION-ONLY actions — not even an operator token may do them
// (`05` §17.5; `09` §3 decision 252, R-1055 / R-1059: a re-issue „stops its backup for a while"). An automatic
// re-issue here would hand those powers to anyone holding the passphrase whenever the box is off or silent
// (a household on holiday). The operator's delete stays the gate: delete the old host, run the installer
// again, and the mint path re-issues exactly as before.
//
// Not wired (staleThreshold 0) or a failed lookup: no verdict, a WARN log line only. Both event types are
// hub-origin only (not in allowedEventTypes) and operator-only. Pinned by r1154_reenroll_test.go.
