The news list API now takes page and limit and returns the total count
instead of a cursor, and the news page uses el-pagination with a
persisted page size.
Let the crawler console set a backfill target per source. Each scheduled
run pages backwards from a checkpoint for at most 20s so real-time
crawling is not blocked. The checkpoint is saved only after a successful
run and is also kept in process memory, because the next trigger may be
queued before the database write lands. cls_depth is excluded since its
list API cannot page into history.
- crawler manager: retry transient errors inside each loop, never let
log writes break supervision, run tasks in a TaskGroup so any escaped
error restarts the container instead of leaving a half-dead process
- market worker: tolerate symbols deleted mid-backfill, retry task
selection and symbol queries, run loops in a TaskGroup
- market WS: validate subscription messages and close the connection
when either the receive or forward side ends
- news pipeline: make first insert concurrency-safe with ON CONFLICT
- market API: only proxy ticker/1s klines for added symbols, map Binance
rate limits to 503 and upstream errors to 502 without blocking
- news API: escape LIKE wildcards in search, return 422 for bad cursors
- market page: cancel pending reconnect timer on unmount
