Two gaps stopped the unrooted path working end to end. The phone had no way to read the focus policy, and the blocklist was only reachable as a hosts file or over plain UDP/53 on the LAN -- while the rooted enforcer actively rejected every DoT connection, so a self-hosted resolver could not have worked even if one existed. focus_owner now loads a generated policy.json instead of hardcoding anything, so config.sh stays the single source of truth across Python, shell and Kotlin. The committed asset is rendered with --redact-home and a test fails if home coordinates ever appear in it. An unknown schema_version is rejected outright: silently accepting a newer schema means enforcing a policy the app has misread, and a misread allowlist is one that blocks the dialer. dns_enforcer.sh rejected ALL port 853 traffic and pinned Private DNS off, every 20 seconds. That is right when DoT is a bypass channel and exactly wrong when DoT is the enforcement channel, which is what an unrooted phone needs -- it has no hosts file to fall back to. With DNS_TRUSTED_DOT_HOST set it now ACCEPTs the trusted resolver before the blanket REJECT, and pins Private DNS to that hostname so the user cannot pick an unfiltered one. Rule order is load-bearing: iptables takes the first match, so an ACCEPT appended after the REJECT would never be reached. expected_rule_count() counts the new rules, because a mismatch there makes chain_intact() rebuild the chain every 20s -- a silent fork storm that also drops the connection each time. With the variable empty the behaviour is byte-identical, so the rooted phone is untouched until this is deployed. setup_dot_resolver.sh terminates DoT with stunnel rather than Caddy: DoT is a raw TLS stream and stock caddy:2.8 has no layer4 module, so using Caddy would have meant an xcaddy rebuild of a container serving five live sites. It reuses the certificate Caddy already renews, so nothing competes for port 80. It binds to the WireGuard address, not 0.0.0.0 -- a public DoT endpoint is an open resolver, and over the existing tunnel it needs no port-forward, no firewall rule and no rate limiting. Verified: example.com resolves, pornhub.com returns 0.0.0.0, TLS 1.3 against the LE cert, and both the LAN and public addresses refuse. The Device Owner checklist is planning only. Checking the device rather than the config settled the one open risk: Google Wallet is not installed and no NFC payment default is set, so the unconfirmable tap-to-pay question does not apply here. The same check found that Aegis, MS Authenticator, Oracle IDM and PKO IKO are absent -- they are in config.sh's whitelist, which describes the rooted phone, not this one.
