LEDMatrix/src/common/sports_shared.py

"""The sports.py surface that is byte-identical in every scoreboard.

Nine plugins ship their own ``sports.py`` -- 41,326 lines in total. Comparing
executable ASTs across the eight that share a lineage, 48 method bodies are
byte-identical in all eight: 1,007 lines carried in eight copies, so 8,056
duplicated lines that must be edited eight times to fix once.

They are the parts with no sport in them. The selection and rotation engine
(``_round_robin_favorites``, ``_favorites_first``, ``_compose_selection``,
``_check_ranking_coverage``, ``_game_divisions``, ``_normalise_quality``), the
font/colour/date subsystem (``_scale_headline_fonts``, ``_scorebug_font``,
``_resolve_font_size``, ``_format_game_date``, ``_font_color``), and the
switch-mode upcoming card (``_draw_upcoming_center_switch``). Nothing here knows
what an inning or a possession is.

Mixins rather than free functions, because every one of these reads host state
-- ``self.config``, ``self.fonts``, ``self.logger``, ``self.display_width``.
Rewriting 48 bodies into free functions would be a rewrite, not a move; as
mixins the bodies move verbatim, which is what keeps the renders identical.

THREE OF THE 48 ARE DELIBERATELY LEFT BEHIND
--------------------------------------------
Byte-identical bodies are not automatically safe to move: a body can bind a
module-level name that differs per plugin, and then it only *looks* the same.

- ``_get_timezone`` calls ``resolve_timezone``, imported from a per-plugin
  module (``hockey_timezone``, ``soccer_timezone``, ...). All eight of those
  differ -- each carries its own ``_WRITEBACK_FIXED_IN`` version -- so moving
  the caller here would silently bind every scoreboard to one plugin's copy.
- ``_extract_game_details`` and ``_fetch_data`` are ``@abstractmethod`` stubs.
  They are the sport-specific contract; satisfying them from a mixin would let a
  plugin instantiate without implementing its own sport.

``_resolve_font_path`` went the other way: it is a module-level function in
sports.py rather than a method, identical in all eight, and ``_scale_headline_fonts``
needs it -- so it is inlined below rather than left behind.

WHAT A HOST MUST PROVIDE
------------------------
Enumerated by walking every ``self.<attr>`` the mixins read and subtracting what
they define, so this list is derived rather than remembered. Everything below is
supplied by all eight scoreboards today.

State: ``config``, ``fonts``, ``logger``, ``display_width``, ``display_height``,
``display_manager``, ``league``, ``sport``, ``mode_config``, ``session``,
``headers``, ``favorite_teams``, ``games_list``, ``current_game_index``,
``last_game_switch``, ``last_update``, ``update_interval``,
``no_data_interval``, ``game_display_duration``, ``stale_game_timeout``,
``other_games_min_quality``, ``schedule_lookback_days``,
``schedule_lookahead_days``, ``game_update_timestamps``,
``_zero_clock_timestamps``, ``_logo_cache``, ``_selection_pools``,
``_ranking_coverage_logged_at``, ``_empty_live_streak``, ``_last_warning_time``,
``_score_grew``.

Methods that stay per-plugin, because they are not identical across the eight
(or, for ``_get_timezone``, because they bind per-plugin modules):
``_get_layout_offset``, ``_by_importance``, ``_other_games_window``,
``_upcoming_date_and_time_text``, ``_extract_game_details_common``,
``_load_division_team_ids``, ``_get_timezone``, ``_is_favorite_game``,
``_is_game_really_over``, ``_is_ranked_game``, ``_passes_other_filters``.

Of the fourteen shared class constants, thirteen are identical everywhere and
live here. Only ``_SCORE_PROBE_TEXT`` varies -- afl and basketball reach three digits
a side and override it, the same two that override ``_SCORE_PROBE`` on
``SportsGameRendererMixin``.

TWINS IN sports_card
--------------------
Many of these have same-named twins in ``src/common/sports_card.py``, which the
scoreboards' ``game_renderer.py`` uses. ``test/test_sports_twins.py`` calls
each pair with the same inputs (the plugins' fixture games in every payload
shape, plus edge cases) and splits them in two:

- Identical: ``_card_option``, ``_vs_text``, ``_format_game_time``,
  ``_coerce_rgb``, ``_crisp_size``, ``_unshare_element_fonts`` (given the same
  element map) and the constant tables. These are now thin wrappers over the
  ``sports_card`` function; ``_format_game_date`` and ``_schema_font_size``
  share its body/parser while keeping their own setting, zone and cache.
  ``_resolve_font_size`` agrees too but keeps its body, because it dispatches
  through the overridable ``_schema_font_size``/``_crisp_size``.
- Different, and pinned as they are: ``_side_is_favorite`` /
  ``_favorite_result`` / ``_recent_score_color`` (flat keys and the host's
  favourites only), ``_weekday_for`` (the plugin's resolved zone, not
  ``config["timezone"]``), ``_font_color`` / ``_ELEMENT_FOR_FONT`` (another
  element vocabulary), ``_element_color`` (passes ``SKIN_MODE``). Each shows
  up in one display mode only, so which side is right is a product decision;
  the test that pins it names the difference.

        It is TOLD, not deduced. The first version walked the MRO for a class
        whose module sits beside a config_schema.json. That works when a test
        imports the plugin itself, and returns None under the real loader, for
        a specific reason worth recording:

            PluginLoader._namespace_plugin_modules renames every bare module a
            plugin brought in (sports, game_renderer, ...) to
            "_plg_<plugin_id>_<module>" and REMOVES the bare entry, so two
            plugins owning a module of the same name cannot collide.

        The class still reports ``__module__ == "sports"``, but
        ``sys.modules["sports"]`` no longer exists, so the walk finds no
        __file__ and falls off the end. The failure was silent and expensive:

            _plugin_dir()       -> None
            _schema_font_size() -> None for every element
            -> a configured size equal to the schema default stops looking
               like a default and is treated as a deliberate user choice
            -> the snap to the font's pixel grid is skipped
            -> 4x6-font.ttf renders at 6 instead of 7: 3px-wide glyphs
               instead of 4px

        On a 256x64 panel that made the odds, the team records and the date row
        hard to read. It was found by a user counting pixels on the panel. No
        gate here caught it: the tests imported plugins directly and the
        safety harness loads them its own way, so neither reproduced the
        loader's renaming.

        The MRO walk stays as a fallback for hosts that declare no
        _PLUGIN_DIR -- the plugins' own probe harnesses build classes with
        ``type()`` -- but it is no longer the primary answer.
