The two address fields were the same Shield spelled twice, and every bug in the
zeroconf/IP-change path came from keeping them in sync. One field now:
* const.CONF_HOST replaces CONF_ADB_HOST / CONF_PROTOCOL_HOST in the setup form,
the options page, the pairing forms, the reconfigure/reauth seeding and the
description copy. ADB port 5555 stays the only port field;
* helpers.entry_host(entry) is the single resolver (options first, then data);
resolve_adb_config and the protocol settings both go through it, so both
transports read the same value at call time (the t32 F1 factory re-read keeps
working: the NEXT built poller sees the new address);
* helpers.seed_host / seed_adb_enabled own the YAML seed's shape rule. A block
may use `host` or the legacy protocol_host/adb_host keys — t41 keeps the old
spelling working — and t32 F4's outcome is unchanged: a protocol-only block
leaves ADB off, an address (or an explicit adb_enabled) turns it on;
* the zeroconf IP-change path collapses the t21-F2 per-host dance into one rule:
the discovery address IS the entry's address, so the entry is updated when it
differs and left alone when it matches. The blank-self-heal and
deliberately-different-ADB-host cases are gone with the duplication — a
second address field cannot express them anymore, and the tests now pin that
(previously "an explicit override is never clobbered");
* the options page exposes the protocol toggle it never had (the page could turn
ADB off but not the protocol);
* button.py (granted to this task) reads the entry's own address instead of
another integration's entity.
The v3 entry migration that maps existing adb_host/protocol_host onto CONF_HOST
and drops the androidtv key lands in the next commit; HA runs migrations before
setup, so an existing entry is never read with the old shape.
Verified: 311 passed / 2 skipped, 312 / 1 with androidtvremote2, ruff clean,
drift engine exit 0 on HEAD. The UI-copy contract tests (every rendered field
has a label in strings.json AND translations/en.json, key trees identical, host
errors name the field) drove the string edits.
"Continue without protocol pairing" switched the transport off for good: the
options flow carries no protocol fields, so nothing in the UI could ever turn
it back on, and the skip copy promised nothing about it (t34 F1). The entry now
answers Home Assistant's Reconfigure action:
* async_step_reconfigure (audit G5) seeds the flow from the entry (title, adb
host/port/enabled, androidtv entity for the host fallback) and re-runs the
pairing step — the address is editable, the Shield shows a PIN, and
_finish_reconfigure persists protocol_enabled=True plus the address that just
paired (so the transport no longer depends on the ADB fallback), adopts the
paired MAC when it differs, and updates + reloads the entry. HA derives the
"reconfigure_successful" abort from the flow source. A Reconfigure visit that
clicks skip aborts honestly with "reconfigure_skipped" (entry untouched), and
an entry that is gone aborts with "reconfigure_entry_missing".
* the skip data_description now states the truth — the transport stays off
until you pair it — and names the later path (the integration's entry menu >
Reconfigure).
* a host corrected on the pairing form now DROPS the session started against the
old address and restarts pairing there, so the typed address is authoritative
instead of being paired against the stale one.
* the success path no longer runs _abort_if_unique_id_configured for a flow
that already owns an entry: core looks the domain up by unique_id, so
re-pairing an entry aborted on itself as "already_configured" (this also
unblocked reauth). The fresh-setup path is unchanged.
* adjacent fix while wiring the same call: _finish_reauth passed
`options_updates`, which core's async_update_reload_and_abort does not accept
(the kwarg is `options`, REPLACE) — the reauth path would have raised
TypeError in production. Both paths now pass `options` and the test stubs
mirror the real signature.
Tests: tests/test_config_flow_ux.py::TestProtocolReconfigure drives reconfigure
from a protocol-disabled entry through to updated options (transport on, host
persisted, other options kept, MAC adopted, reload recorded), a corrected host
reopening the PIN step against the new address, the skip abort, and the
missing-entry abort; TestCopyContract gained the F1b copy pin. Against HEAD's
config_flow.py all four reconfigure tests fail (no async_step_reconfigure).
