Read-side cutover for the binary scores store and a companion
cleanup that removes the biggest remaining DB write from the hot
path.
Propagation.scores_at/3, available_valid_times/1, latest_valid_time/0,
latest_valid_time/1, earliest_valid_time/1, point_detail/4, and
point_forecast/3 all now prefer ScoresFile and fall back to the
propagation_scores table when a file is missing. The map render
path reads from /data/scores first; Postgres stays as a safety
net while dual-write is on. point_detail still pulls factors from
Postgres (analysis-hour rows only) and coalesces nil to an empty
map so the JS popup iterates cleanly.
replace_scores/2 is now gated by a postgres_writes_enabled? flag
(runtime env MICROWAVEPROP_SCORES_POSTGRES=false, or the
:propagation_scores_postgres app env key) so the binary-only path
can be benchmarked locally without the DB insert. Default stays
true.
PropagationGridWorker no longer calls store_hrrr_profiles —
persisting 92k grid rows × 19 forecast hours of JSONB profiles
was ~12 min of wall time per chain for a table only
AsosAdjustmentWorker read from. Per-contact HRRR enrichment
through HrrrFetchWorker still writes its own (is_grid_point:
false) rows. AsosAdjustmentWorker is disabled in all three cron
configs since its data source is gone.
DataCase resets the scores tree between tests so per-test
ScoresFile writes don't leak across cases, and ScoresFileTest
switches to async: false because it mutates the global
:propagation_scores_dir env.
