Sibling standalone Cargo crate `harness/` under experiments/2026-05-12-cross-model-authoring/ (out-of-workspace idiom carried forward from cma.1 verbatim). Six modules: strip_locations (regex pass for form-asymmetric location info, calibrated against five real `ail check`/`ail parse` stderr captures), pipeline (subprocess wrapper for parse|check|build + 5s-timeout exec; preflight on ail+clang), ionos (blocking reqwest client + retry policy per spec), mock (canned-response loader), scoring (CSV + summary.md), tasks (definition struct + loader). main.rs ties them into the per-(cohort,task) loop with budget accounting and per-turn artefact recording. Four MVP tasks land with reference solutions that compile, build, and execute green through the actual ail+clang pipeline: t1_add_three (chained `+` + io/print_int), t2_length (polymorphic List + recursion), t3_main_prints (minimal IO module), t4_count_zeros (prelude Eq Int + branched if). Reference solutions stay in canonical AILang form — param_modes is omitted when every parameter is the Implicit default, consistent with the existing examples/ corpus. 13/13 tests green: 5 lib unit (strip_locations) + 5 integration (strip_locations against verbatim captured fixtures) + 1 verify_references (drives every reference through the real ail+clang pipeline) + 1 mock_full_run (full eight-row sweep with mixed green-on-turn-2 + turn-limit cycles) + 1 budget_abort (synthetic budget exhaustion with budget_abort rows + run_status). Two implementer-phase repairs beyond the plan, both small and surfaced in the iter journal Concerns: 1. pipeline.rs renames the program file to `<module-name>.ail.json` between parse and check because `ail check` enforces filename stem == module name (compiler contract the plan did not anticipate). 2. main.rs fills synthetic budget_abort rows for tasks the outer loop never reached so scores.csv preserves the expected eight-row shape on budget exhaustion. One plan/text mismatch carried over: README "Total 8 passed" reflects the plan's four-suite count; actual sweep produces 13. Doc-fix candidate for cma.3. cma.3 (live IONOS run + DESIGN.md addendum + roadmap edits) remains out of scope.
Cross-model authoring-form test
Empirical measurement of whether .ail.json or .ailx is the form a
foreign LLM author reaches for and succeeds with. Single subject for
v1: Qwen3-Coder-Next via IONOS. Two blind cohorts; same four tasks.
Parent spec: docs/specs/2026-05-12-cross-model-authoring-form-test.md.
Layout
master/spec.md— canonical mini-spec source (form-agnostic prose +{form-only: X}blocks +{example: id}markers).master/examples/*.ail.json— AST source-of-truth; each example prints to either form via the existing roundtrip machinery.master/tasks/*.task.json— task definitions consumed by the harness. Authored in cma.2, not cma.1.render/— standalone Cargo crate, outside the root workspace, builds the renderer binary.rendered/json.md,rendered/ailx.md— projected mini-specs, checked into the repo for review.harness/— Authored in cma.2.runs/<date>-<hash>/— populated byharnessduring a live run.
Running the renderer
cargo run --manifest-path experiments/2026-05-12-cross-model-authoring/render/Cargo.toml -- \
--master experiments/2026-05-12-cross-model-authoring/master \
--rendered experiments/2026-05-12-cross-model-authoring/rendered
Running the tests
cargo test --manifest-path experiments/2026-05-12-cross-model-authoring/render/Cargo.toml
Three integration tests: example_roundtrip (each example loads,
prints to AILX, reparses to the same canonical bytes), spec_completeness
(every AST variant in ailang_core::ast is exercised by at least
one example), token_balance (form-only blocks balanced within ±5%
across the two rendered files).
Running the harness
Live mode (one full eight-run sweep, ~480k tokens budget by default):
export IONOS_API_TOKEN="<token>" # see roadmap entry for token provenance
cargo run --manifest-path experiments/2026-05-12-cross-model-authoring/harness/Cargo.toml -- \
--rendered experiments/2026-05-12-cross-model-authoring/rendered \
--tasks experiments/2026-05-12-cross-model-authoring/master/tasks \
--out experiments/2026-05-12-cross-model-authoring/runs \
--model Qwen/Qwen3-Coder-Next
The harness pre-flights ail --version and clang --version before
the first API call. Set AIL_BIN if ail is not on PATH.
Mock mode (offline; CI-friendly; bypasses the IONOS API):
cargo run --manifest-path experiments/2026-05-12-cross-model-authoring/harness/Cargo.toml -- \
--rendered experiments/2026-05-12-cross-model-authoring/rendered \
--tasks experiments/2026-05-12-cross-model-authoring/master/tasks \
--out /tmp/mock-runs \
--model mock \
--mock experiments/2026-05-12-cross-model-authoring/harness/tests/fixtures/mock_full_run.json
Tests:
cargo test --manifest-path experiments/2026-05-12-cross-model-authoring/harness/Cargo.toml
Four test suites: strip_locations (5), verify_references (1),
mock_full_run (1), budget_abort (1). Total 8 passed.
