New hardware-free module src/common/sports_live_fetch.py, copied from
ledmatrix-plugins claude/family9-reconcile once the nine scoreboards made
_fetch_todays_games (seven bodies when measured) and _fetch_odds (three) one
body each. Both live on the plugins' SportsCore, so one mixin,
SportsLiveFetchMixin, carries exactly those two plus the odds worker
_drain_odds_queue; no manager gains a method it lacks today.
Owner decisions (2026-10-12):
- Live scores are always fresh: every poll asks ESPN through
get_espn_scoreboard and leaves the answer under the shared
espn_scoreboard_cache_key for its dates (max_age=1: only a copy another
reader fetched within the last second is reused). The plugins' 30 s
<sport_key>_scoreboard_current cache is gone.
- College basketball is asked by date like every other league (ESPN
answered single dates for both college leagues on 2026-10-12).
- Odds never block update(): one daemon worker per manager answers a queue
and attaches each line in place under _games_lock; one batch in flight per
manager, games queued meanwhile join it, every dict queued for an id gets
the one answer. show_odds, the two odds intervals and a missing odds
manager (debug, not ERROR) are respected.
- An answer whose events is not a list is no games.
Fix: get_espn_scoreboard() no longer caches an answer whose events is not a
list ("events": null), which every reader of the shared key inherited; it is
still returned to the caller.
- test/test_sports_live_fetch.py: the plugins' pinned cases (requests,
dates and keys at 10:00 and 02:00 Eastern, freshness, malformed and failed
answers, odds that never block and land later, the intervals, one batch per
manager, a worker that cannot start, update and display on two threads),
plus the host contract. Mutation-checked (11 mutants, all caught).
- test/test_sports_live_fetch_parity.py: with LEDMATRIX_PLUGINS, compares
each body with every plugin copy. Passes against claude/family9-reconcile;
fails against the pre-reconcile tree.
- test/test_espn_scoreboard_cache.py: the null-events regression.
- mypy ratchet, src/common/README.md, CHANGELOG (Unreleased: New modules,
Fixes), docs/SPORTS_UNIFICATION.md family 9 status and decisions.

The disk cache's unchanged-payload skip now ignores a CacheManager.set() record's timestamp, so unchanged re-saves are skipped; a skip moves the file's mtime to the new timestamp instead, and readers take a record's age from the newer of the two (never more than an hour past the embedded timestamp). Per-plugin plugin_metrics:<id> records become one plugin_metrics_snapshot written at most once a minute, and CacheManager builds its ConfigManager on first use. On hdpi, cache file writes went from ~37 to 8.6 a minute.

Fetch service stage 2: one ESPN scoreboard cache key shared across the sports base classes (legacy keys still read), and a max-age response cache in the fetch service.
