t48 F1: source_list stringified the app map's values without filtering, so a
hand-edited map with a blank name ("com.x=") put an empty string in the dropdown.
That entry is worse than useless — it is a dropdown item whose only possible outcome
is an error, because select_source has to reject an empty name as an unknown source.
source_list now drops blank and whitespace-only names. The values themselves are
untouched: no name is rewritten or trimmed here, because the reverse lookup matches on
them, so for a well-formed map the list stays byte-equal to the Browse tree's child
titles (same _app_directory accessor, same order) — pinned by comparing the two
directly, for the user's map and for the curated default. The reverse lookup is
unchanged.
Tests (tests/test_media_sources.py, 3 new; tests/test_standalone_setup.py, 1 new):
a hand-edited map with "" and " " entries offers only the real names; the offered
list equals the Browse tree titles for well-formed maps (both map and curated
default); the surviving entries still resolve AND launch through select_source, and a
blank name still resolves to nothing; and the editor keeps rejecting "com.x="
(_app_map_from_text returns None, the page answers invalid_app_map and stores nothing
half-way), so a blank name cannot get in that way either.
RED PROOF: with the filter removed, exactly the two blank-name tests fail — the blank
appears in the list, and the entry has no package to resolve to (1 passed / 2 failed;
the byte-equality test passes either way, which is the "well-formed list unchanged"
half of the claim) — while the rest of the file is green; restored, 20 pass.
Verified: 458 passed / 2 skipped, 459 / 1 with androidtvremote2, ruff clean, drift
engine exit 0 under real HA (23 modules, 58 imports, 164 relative imports, 36 call
arguments, 7 awaited HA calls).
Residual, deliberately NOT touched here (out of this repair's scope, and pre-existing):
a blank map entry still reaches the Browse tree as an empty child title, and a PADDED
name (" TiviMate ", hand-edited only — the editor strips) still fails the reverse
lookup because the map value is matched unstripped. Both are hand-edited-map edges;
say the word and either can be a follow-up.
The last piece a universal-media-player replacement needs: a dropdown of the apps,
an answer to what is on screen, and a way to pick one — all reading ONE app directory
(the user's Apps map, else DEFAULT_APP_DIRECTORY), so the dropdown can never offer a
name the launch path cannot resolve. That invariant is pinned by a test that walks
source_list and resolves every entry.
* `source_list` — friendly names in directory order (the user's map order, or the
curated list), from a new `_app_directory` accessor that the browse tree now shares.
* `source` — the foreground app's resolved name via the existing `resolve_app_name`
chain (map → cached device-manifest label → raw package), i.e. exactly `app_name`,
so the media player and the Current App sensor cannot disagree.
* `select_source(name)` — a configured select_source script still takes precedence
(t44, unchanged: selecting a source can be more than launching an app); without one
the name is resolved back to its package and launched over the shared
`play_media("app", …)` path, so the native semantics are the ones play_media already
had. Accepts a raw package id (what the browse tree publishes) and matches names
case-insensitively; an unknown or empty name raises
ServiceValidationError(translation_domain="nvidia_shield",
translation_key="unknown_source", translation_placeholders={"source": …}) — a
translated error, never a silent no-op — with new copy in BOTH strings files.
* SELECT_SOURCE is advertised when EITHER a select_source script is configured OR
source_list is non-empty; VOLUME_SET stays script-only (the protocol has no
absolute-volume key), and the two flags are pinned as independent.
Two t44 tests were updated because this is a deliberate behaviour change: "no native
path" is now only true of volume_set, and SELECT_SOURCE is advertised by default
because the curated directory always offers something.
Also: rewriting the strings files re-indented the seven script labels added in t44
(they were valid JSON but sat two levels shallow); the diff there is that fix plus
the new key.
Verified: 441 passed / 2 skipped, ruff clean, drift engine exit 0 under real HA
(23 modules, 59 imports, 157 relative imports, 36 call arguments, 7 awaited HA calls).
