iter ms.2: Qwen retroactive re-run + first CodeLlama-13b-Instruct run + DESIGN.md §Decision-6 addendum extended to two subjects

Two live IONOS harness invocations with the ms.1 fix in place:

  - Qwen/Qwen3-Coder-Next   → runs/2026-05-12-080864/  (RUN_STATUS=ok)
  - meta-llama/CodeLlama-13b-Instruct-hf
                            → runs/2026-05-12-9197fd/  (RUN_STATUS=ok;
                              2/8 JSON cells terminated as api_failure
                              on turn 1 zero-token — transient IONOS
                              terminal error, disclosed in addendum)

Per-cell results (reached/4, prompt tokens, completion tokens):

  Qwen      JSON     1/4   182,378   14,972
  Qwen      AILX     1/4   110,575    3,474
  CodeLlama JSON     0/4   116,015    2,711   [2 cells api_failure]
  CodeLlama AILX     2/4    93,017    2,234

Both subjects agree on direction: AILX cohort cheaper on prompt
tokens (Qwen 61%, CodeLlama 80% of JSON-cohort spend) and on
completion tokens (Qwen 23%, CodeLlama 82%); AILX reached-green
≥ JSON reached-green for each subject. Three of four
first-attempt-green cells across the two subjects are AILX.
Failure classes split symmetric to form: JSON cohorts fail at
typecheck, AILX cohorts at parse — each form's
front-of-pipeline check.

DESIGN.md §"Decision 6 / Empirical addendum (2026-05-12)"
replaced: 2-column single-subject view → 4-column two-subject
view, framing paragraph reports direction agreement and the
api_failure / Qwen-rerun-noise anomalies, scope paragraph
updated to 'two subjects, n=1 each, deterministic; not a
verdict — a universal claim would need ≥3 subjects with
statistical robustness'.

Roadmap P3 'Multi-subject expansion' entry removed; scoped
goal met for two subjects.

Milestone token spend: prompt 501,985 + completion 23,391
= 525,376.
