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.

+Cross-model measurement against two foreign LLMs via IONOS,
 temperature=0, top_p=1, max-turns=5. Two blind cohorts on the same
 four MVP tasks (`t1_add_three`, `t2_length`, `t3_main_prints`,
-`t4_count_zeros`); each cohort sees only its own form's
-mini-spec. Run directory:

+`t4_count_zeros`); each cohort sees only its own form's mini-spec.
+Subjects (both runs use the pipeline-error-formatting fix from ms.1
+so JSON-cohort feedback carries the full anyhow cause chain):

-|---|---|---|
-| reached green | 1/4 | 2/4 |
-| first-attempt green | 0/4 | 1/4 |
-| mean turns-to-green (green only) | 2.0 | 2.0 |
-| total prompt tokens | 191,768 | 95,417 |
-| total completion tokens | 15,376 | 2,587 |
-| top error class | check (×4) | parse (×3) |

-The AILX cohort reached green on more tasks at roughly half the
-prompt-token cost and one-sixth the completion-token cost. The
-only first-attempt success in the entire run was AILX on
-`t3_main_prints` (~5 lines of tagged s-expr; the JSON-cohort
-counterpart was ~23 lines of structured JSON and required a
-correction turn). JSON-cohort failures clustered in the
-typecheck-stage; AILX-cohort failures clustered in the parse stage,
-which is the symmetric front-of-pipeline check for that form.

-**Scope of this addendum:** single subject, single deterministic

-pending a multi-subject expansion — see the roadmap entry
-"Multi-subject expansion (cross-model authoring-form follow-up)"
-for the next-step queue.
+Both subjects show the same direction on every metric the table
+tracks. AILX is cheaper than JSON on prompt tokens (Qwen 61%,
+CodeLlama 80% of the JSON cohort's spend) and cheaper on completion
+tokens (Qwen 23%, CodeLlama 82%). AILX reached-green is greater than
+or equal to JSON reached-green for each subject (Qwen ties at 1/4;
+CodeLlama strictly dominates, 2/4 vs 0/4). The failure-class
+symmetry observed on the original Qwen baseline holds for both
+subjects: JSON cohorts fail at the typecheck stage, AILX cohorts at
+the parse stage — each form's front-of-pipeline check. Three of the
+four first-attempt-green cells observed across the two subjects are
+AILX (Qwen-AILX t3, CodeLlama-AILX t1, CodeLlama-AILX t3); the
+fourth is Qwen-JSON t3, the same task the original baseline already
+flagged as the JSON-form's only first-attempt success. Two CodeLlama
+JSON-cohort cells (`t2_length`, `t4_count_zeros`) terminated as
+`api_failure` on turn 1 with zero tokens consumed — a transient
+IONOS-side terminal error, not a model-output failure; CodeLlama
+JSON-cohort numbers therefore average over 2 informative cells, not
+4. The Qwen re-run also shifted by one cell against the cma.3
+baseline (AILX 2/4 → 1/4, JSON 1/4 → 1/4) despite identical
+temperature=0 inputs; this is IONOS-side state-of-day noise on a
+single deterministic re-run, not an effect of the ms.1
+feedback-formatting fix (which only changes JSON-cohort prompt
+content).
+
+**Scope of this addendum:** two subjects, n=1 each, deterministic.
+This is a second data point pointing in the same direction as the
+first, not a verdict. The universal claim of this Decision (".ailx
+is the AI authoring projection") would need ≥3 subjects with
+statistical robustness to ratify; both current points point the
+same way (AILX cohort cheaper and at-least-as-green) but neither
+the sample size nor the cross-call noise observed in the Qwen
+re-run is enough to close out the Decision.

+## Summary
+
+Two live IONOS harness invocations executed with the ms.1 fix in
+place: a Qwen3-Coder-Next retroactive re-run
+(`runs/2026-05-12-080864/`, RUN_STATUS=ok) and a first-ever
+CodeLlama-13b-Instruct run (`runs/2026-05-12-9197fd/`, RUN_STATUS=ok
+at the run level; 2 of 8 cells terminated as api_failure on turn 1
+with zero tokens — transient IONOS-side terminal error, disclosed
+in the addendum and below). DESIGN.md §"Decision 6 / Empirical
+addendum (2026-05-12)" replaced with a four-column per-cell table
+plus a framing paragraph; roadmap P3 "Multi-subject expansion"
+entry removed.
+
+Both subjects point the same way on every measured axis: AILX
+cohort is cheaper than JSON cohort on prompt tokens (Qwen 61%,
+CodeLlama 80%) and on completion tokens (Qwen 23%, CodeLlama 82%),
+and AILX reached-green ≥ JSON reached-green for each subject (Qwen
+ties at 1/4; CodeLlama strictly dominates 2/4 vs 0/4). Three of the
+four first-attempt-green cells across the two subjects are AILX.
+Decision 6 is not ratified — n=1 per subject across two subjects is
+not statistical robustness — but the second data point points
+consistently. The roadmap entry was removed because the brainstorm
+spec was scoped to two subjects, not because the universal claim is
+closed; a future ratification iteration would re-open it.
+
+Anomaly disclosure: the Qwen re-run shifted by one cell vs the cma.3
+baseline (AILX 2/4 → 1/4, JSON 1/4 → 1/4) at identical
+temperature=0; this is IONOS-side state-of-day noise, not an effect
+of the ms.1 feedback fix, which only changes JSON-cohort prompt
+content. The two CodeLlama JSON api_failure cells (`t2_length`,
+`t4_count_zeros`) were not re-run — the carrier constraint forbids
+exploratory token spend, and the addendum discloses the partial
+sample directly.
+
+Roadmap P3 "Multi-subject expansion" entry removed in this iter.

+## Per-task notes
+
+- iter ms.2.1: Qwen retroactive re-run via harness — new run dir
+  `experiments/2026-05-12-cross-model-authoring/runs/2026-05-12-080864/`,
+  RUN_STATUS=ok, 8/8 cells populated. AIL_BIN set to
+  `target/release/ail` (no `~/.local/bin/ail`); harness picks it up
+  via env-var resolution at `pipeline.rs:42`.
+- iter ms.2.2: CodeLlama-13b-Instruct first run via harness — new
+  run dir
+  `experiments/2026-05-12-cross-model-authoring/runs/2026-05-12-9197fd/`,
+  model id `meta-llama/CodeLlama-13b-Instruct-hf` (Boss-pre-flighted
+  IONOS catalogue id), RUN_STATUS=ok. 6/8 cells informative; 2/8
+  json cells (`t2_length`, `t4_count_zeros`) `api_failure` on turn 1
+  zero tokens.
+- iter ms.2.3: Per-cell metrics computed via direct scores.csv
+  read — see addendum table. Total milestone token spend: prompt
+  501,985 + completion 23,391 = 525,376.
+- iter ms.2.4: DESIGN.md lines 604-636 replaced with new
+  four-column addendum block (~50 lines including the framing
+  paragraph). Subjects named with canonical IONOS model ids and
+  run-dir pointers; framing paragraph reports direction agreement,
+  failure-class symmetry, first-attempt tally, api_failure anomaly,
+  and Qwen-rerun noise. Scope paragraph extended to "two subjects,
+  n=1 each".
+- iter ms.2.5: roadmap.md lines 253-268 removed (P3 multi-subject
+  entry + context note); journal file written. INDEX.md is NOT
+  edited by this agent per the Iron Law; the Boss appends the
+  ms.2 line at commit time. Suggested INDEX line (per plan Task 5
+  Step 3):
+  `- 2026-05-12 — iter ms.2: Qwen retroactive re-run + first CodeLlama-13b-Instruct run; DESIGN.md §Decision-6 addendum extended to four cells; roadmap P3 removed → 2026-05-12-iter-ms.2.md`
+- iter ms.2.6: Spec acceptance criteria sweep (1-7 all green); 14
+  harness tests still pass.
+
+## Spec acceptance sweep
+
+1. ms.1 `pipeline.rs:118` reads `format!("check: {e:#}")` + RED→GREEN unit test → green (ms.1 working tree).
+2. ms.1 existing 14 harness tests still pass → green (verified Task 6 Step 2).
+3. CodeLlama-13b-Instruct-hf runs to completion against IONOS endpoint, RUN_STATUS=ok at run level → green; model id recorded above.
+4. Qwen3-Coder-Next re-run completes, RUN_STATUS=ok, 8 cells; distinct dir from cma.3 baseline → green.
+5. DESIGN.md §"Decision 6 / Empirical addendum" extended with follow-up paragraph + four-cell-shaped table → green.
+6. Roadmap P3 entry removed; one-line mirror above → green.
+7. Per-iter journal (this file) written → green. INDEX.md ms.2 entry is Boss-side per the Iron Law; suggested line is in the end-report.
+
+## Concerns
+
+- 2 of 4 CodeLlama JSON cells are `api_failure` (terminal IONOS
+  error on turn 1). Per the Plan's branch (c) and the carrier's
+  "no exploratory re-runs" constraint, not re-attempted. The
+  addendum and journal disclose this directly; the
+  CodeLlama-JSON column's prompt-token average is therefore over 2
+  informative cells, not 4. Effect on the AILX-cheaper conclusion:
+  none in direction; the prompt-token gap is preserved over the
+  two informative JSON cells. If a future iteration re-runs
+  CodeLlama at lower IONOS load, this should resolve.
+- Qwen-re-run vs cma.3-baseline drift (1 cell) at identical
+  temperature=0 is IONOS noise on a single deterministic call. A
+  future ratification iteration should add ≥3 repetitions per
+  subject to bound this noise, not rely on a single
+  temperature-zero call.
+
+## Known debt
+
+- The pre-existing 3 warnings in `harness/src/ionos.rs` lines 86,
+  125, 137 (`last_err` assigned but never read) survived ms.1
+  and ms.2. Not in scope here; cma.2 inheritance.
+- Decision 6 universal-claim status is still "second data point,
+  not verdict". A future ratification iteration would need ≥3
+  subjects with statistical robustness. Out of scope for ms.
