Persist user_data (PicklePersistence) so an in-flight /addgamer username
prompt survives a bot restart instead of being silently swallowed by
handle_username when the in-memory awaiting flag is gone.
Collapse periodic-check backlog into a single request spanning the whole
missed gap instead of replaying it one period_minutes window at a time —
with enough tracked gamers sharing one RequestQueue, per-window replay
could never catch up and the checkpoint fell further behind indefinitely.
Notification period label now reflects the actual queried span (minutes/
hours/days) instead of the configured interval, so a weeks-old catch-up
no longer gets mislabeled as "for 15 minutes".
- /getgamers: column-aligned monospace table (username, ratings, period).
- Per-mode stats (rating/wins/losses/draws): column-aligned block, dropped
the meaningless multi-game average accuracy row.
- format_stats_response/format_period_notification now wrap the whole
message in a single markdown code block instead of alternating
plain-text headers and separately-fenced tables.
- Rating row gets an emoji prefix to match the other three rows, so
Telegram's monospace rendering keeps all values in the same column.
Set awaiting_addgamer_username as soon as the menu is shown so typing a
username directly (without tapping the button) is handled instead of
being silently ignored. Also stop reporting a valid username as "not
found" when Lichess returns a non-404 error (rate limit/timeout), and
surface an error message if the addgamer menu itself fails to send.
Games-of-period responses can now include a per-game breakdown
(include_games) with Lichess post-analysis accuracy, plus which side
the tracked player was on and their rating change for that game.
- lichess_client.py requests accuracy=true from Lichess; stats_service
computes per-mode average accuracy and builds GameRow entries
(tracked_is_white, tracked_rating_diff) for blitz/rapid/classical
- /games/{username}/period gained an include_games query param
- formatters.py renders a column-aligned monospace table per game:
outcome circle (win/loss/draw relative to the tracked player),
rating change, accuracy, names/ratings, result — for today/yesterday
and periodic notifications; week keeps an aggregate accuracy line
- usernames are Markdown-escaped before formatting since messages are
now sent with parse_mode='Markdown'
