Milestone "Cross-model authoring-form test" closed. Live IONOS run
against Qwen/Qwen3-Coder-Next executed at temperature=0, max-turns=5,
token-budget=500000. Raw dataset under runs/2026-05-12-df7531/:
RUN_STATUS=ok, scores.csv with 8 rows (4 tasks × 2 cohorts),
summary.md, plus 156 per-turn raw artefacts (request/response/program/
stderr/stdout) preserved for any future analysis.
Headline numbers:
- AILX cohort: 2/4 green, 1/4 first-attempt, ~95k prompt + ~2.6k completion
- JSON cohort: 1/4 green, 0/4 first-attempt, ~192k prompt + ~15k completion
- Only first-attempt success was AILX on t3_main_prints (~5 lines of
tagged s-expr vs ~23 lines of structured JSON for the JSON cohort's
turn-1 attempt that needed correction).
- Per spec, single subject + single deterministic run = data point,
not verdict.
DESIGN.md §"Decision 6: authoring surface" gains an "Empirical
addendum (2026-05-12)" subsection: 6-row metric table, illustrative
t3 contrast, explicit single-subject scope note pointing at the
roadmap follow-up entry for multi-subject expansion.
Roadmap: P2 entry "Cross-model authoring-form test" removed (this
journal is the convention's one-line mirror); P3 entry
"Multi-subject expansion (cross-model authoring-form follow-up)"
added with the run dir named as baseline.
Milestone artefacts span three iters (cma.1 master mini-spec +
renderer; cma.2 harness + tasks + reference solutions; cma.3 this
live run + DESIGN.md addendum + close).
