Bug Description

After upgrading to OpenClaw 2026.5.4, Feishu bot accounts intermittently fail to send replies. Messages are received and processed by agents, but dispatch complete (queuedFinal=false, replies=0) and no message is sent to Feishu.

This affects both group chats and DM (p2p) sessions — it is not limited to group chat, though it is more prevalent there.

Reproduction Steps

1. Send any message to a Feishu bot (DM or group)
2. Observe the gateway log: feishu[account]: dispatch complete (queuedFinal=false, replies=0)
3. No reply appears in Feishu

Affected accounts: happylife, capital-market, history-research, lc, macmini (all DM and group paths)

Root Cause Analysis

The bug is in the OpenClaw core reply dispatch mechanism:

1. When a message triggers a reply without a streaming card, the reply dispatcher's counts.final remains 0
2. Messages with Started Streaming card → replies=1 ✅
3. Messages without streaming card → replies=0 ❌

Evidence from gateway logs (macmini DM path):

# Working (with streaming)
Started Streaming: cardId=..., messageId=om_...
dispatch complete (queuedFinal=true, replies=2)
Closed streaming

# Broken (without streaming)
DM from ou_...: [message content]
dispatching to agent
dispatch complete (queuedFinal=false, replies=0)  ← no streaming card

Expected Behavior

Every message that triggers an agent response should result in replies>=1 in the gateway log and a reply sent to Feishu, regardless of whether a streaming card is used.

Possible Cause

The counts.final logic in the core dispatch module may be incorrectly gated on streaming card presence. When a reply is generated without a streaming card (i.e., a simple text reply), the reply dispatcher is not being properly settled/queued, resulting in queuedFinal=false and replies=0.
