+# PR #18 Update Summary
+
+## Dispatch execution evidence
+
+The branch now fixes one place to record dispatch execution evidence, but the
+current reality is still `send_performed: no`.
+
+## Post-send state update
+
+The branch now fixes the post-send state update surface, but that state is not
+entered until the fixed outbound dispatch packet is actually sent.
+
+## Current label
+
+`continue_sharpening`
+
+## Next step
+
+Dispatch execution is next. Attach is still blocked.

+# TPI-019 Decision
+
+## Current bottleneck
+
+One returned filled provider block is still missing.
+
+## Decision label
+
+`continue_sharpening`
+
+## Exact next action
+
+Perform the fixed outbound dispatch packet and record concrete send evidence
+immediately after that send occurs.
+
+## Branch rule
+
+- returned filled block absent -> `continue_sharpening`
+- returned block accepted + landing verified -> `promote_to_execution_resume`
+- returned block accepted + attach/landing failure -> `move_to_failure_ledger`

+Use this note to record whether the fixed outbound dispatch packet was actually sent in this turn, and by whom, where, and with what reference.
