Brummel 577bb6be43 experiment(cma): SMA authoring probe against Qwen3-Coder-Next (refs #68 )

Probe whether a foreign model can write the Series SMA worked example in
AILang Form-A from the mini-spec + Series API alone. Two live runs, neither
reached green, but a clean progression:

- Run 1 (stock API doc): 6 byte-identical turns, blocked on (app new ...) —
  Qwen treats the  term head as an ordinary function.
- Run 2 (new clarified as a term head): clears that; ownership threading
  comes out idiomatically right (nested let s = Series.push s v), but
  S-expression bracketing breaks (push sees 4 args, not 2).

Cross-cutting: Qwen clears a hurdle only with per-quirk guidance and never
converges from the ail check diagnostic (same failure repeated all 6 turns
in both runs); the failures are Form-A bracket-shape errors, not semantic.
n=1 model, single session. Driver: sma_probe.py; raw logs sma-probe-run{1,2}.md.
Live IONOS run, with consent.

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'

Turn 1 — `check` ❌
