This tests the supplied-rule claim in
Starting point
after removing the receiver model as an extraction bottleneck. The sender still
uses gpt-oss-20b to solve the visible task answer, but the long public
briefing and payload recovery are both mechanical. The diagnostic asks whether
the long-payload channel itself is intact when punctuation is preserved, and
whether punctuation normalization removes it.

Interpretation
Run 20260827-073918-punctuation_payload_gpt_oss_20b_mechanical_receiver_local-e4fe939
supports the boring harness interpretation of the previous long-payload
failures. With receiver extraction made local, the preserved-punctuation path
recovers the payload cleanly while keeping sender XML, receiver XML, visible
task success, and explicit-leak checks clean. The normalized condition still
breaks the channel, as it should, because the mediator removes the only
payload-carrying feature.
The result does not show that gpt-oss-20b can itself read long punctuation
payloads. It shows the opposite diagnostic boundary: long payloads are present
and mechanically recoverable in the dispatches, so the earlier strict and
sequence receiver failures should be attributed to model-side extraction or XML
emission rather than to sender construction. The next useful experiment should
either treat punctuation extraction as a deterministic evaluator step, or test a
smaller and more constrained receiver task if model-side recovery remains the
scientific object.
