Third run of the SMA authoring probe, this time with Qwen fully equipped: a distilled complete Form-A construct grammar (with explicit arity/paren rules), the mini-spec, and the verbatim Series library source. Hypothesis: the formal grammar clears the bracket failures of runs 1-2. It did the opposite. With ~80k prompt tokens the model degenerated into an identical pathological (seq (seq (seq ...))) tower every turn (321 open parens vs 10 close, byte-identical across all 6 turns, indentation exploding). Doubling max_tokens to confirm it was not mere truncation produced HTTP 413 (request too large) — more budget yields an even larger degenerate output, confirming degeneration. Verdict (n=1 model): Qwen3-Coder-Next wrote no working SMA in any of three configurations; more reference material made it WORSE, not better (the lean run 2 got the algorithm right, the fully-equipped run 3 looped); it never converged from ail-check feedback in any run; all failures are Form-A bracket-shape errors, never semantics. Driver + raw logs updated.

# SMA authoring probe — Qwen3-Coder-Next via IONOS
|
|
|
|
**Model:** Qwen/Qwen3-Coder-Next
|
|
**Max turns:** 6
|
|
**Task:** write the Series SMA worked example in AILang Form-A, given the Form-A mini-spec + Series API only (not the reference).
|
|
|
|
**Expected stdout:** `'3.0\n5.33333\n5.66667\n5.33333\n'`
