Two issues from live testing:
- Double-logged hand. The chat turn can execute TWICE — the SSE stream and the
blocking fallback both run server-side (two 'chat request' lines, 1s apart) — a
pre-existing double-execution (it also duplicated user messages) that the new
logging guarantee turned into duplicate HANDS. record_hand is now idempotent:
_recent_duplicate_hand returns an identical hand (same session, hole cards, board;
NULL-safe) recorded in the last few minutes, so the second run reuses it instead
of inserting. A system-of-record records an event once.
- Button straddle dropped. The parse prompt had no straddle logic. Added a STRADDLES
rule: record any straddle as a preflop `post` by the straddler with its amount and
respect the action order (button straddle acts last preflop, action opens in the
SB; UTG straddle opens to its left). Verified: a btn-straddle hand now parses the
straddle as {pos: BTN, action: post, amount: 6}.
Note: the underlying double turn-execution (stream + fallback) is a separate web-layer
bug worth fixing at the source — it wastes a full LLM turn and still double-persists
chat messages. Filed for a follow-up. 6 tests; suite 223 green.
