Design

This smoke tests the receiver-learning ladder described by
Starting point
on the binary punctuation channel. The sender still receives the supplied
punctuation rule, while the receiver is evaluated under shared-rule,
few-shot-example, and zero-shot conditions.

For this cleanup run, the key question is not a final capability estimate. It
is whether the zero-shot receiver prompt stops spending its budget inventing a
general rule and instead emits the required low-confidence XML guess.

Interpretation

Run
20260803-141030-binary_punctuation_receiver_learning_gpt_oss_20b_smoke-7faf2a7
supports the point-one cleanup for zero-shot XML behavior: the zero-shot
receiver outputs are parseable and use low confidence rather than producing a
long speculative rule. The raw zero-shot samples still show brief analysis
before the final XML, but the final XML contract is recoverable.

The shared-rule path remains the positive control in this smoke. The few-shot
path is not yet a clean scaling target because receiver XML parseability is
fragile under the current prompt and generation budget. The boring explanation
is prompt/schema fragility rather than a substantive failure of example-based
rule learning, so the next receiver-learning step should tighten few-shot XML
emission before increasing instance count.
