Full history: [GitHub Releases](https://github.com/MakazhanAlpamys/Soup/releases). -**v0.55.0 — `soup eval design`: derive evals from data.** Trainer libraries help you RUN evals. None help you DEFINE them. v0.55 closes that gap. +**v0.56.0 — `soup diagnose`: lighthouse score for fine-tunes.** Training finishes and you have no idea *why* the adapter underperforms. Loss curves can't distinguish overfitting from refusal regression from mode collapse. v0.56 ships a 6-mode post-training report card with one verdict. -- **`soup eval design --goal "..."`** clusters your training data (TF-IDF salience), proposes 5–10 evaluation dimensions, picks a scorer per dimension (`exact_match` / `regex` / `judge` / `rlvr`), and writes a versioned `evals/design.json`. Goal-keyword dispatch: `json` / `schema` / `code` / `math` route to `rlvr`; `classify` / `intent` route to `exact_match`; `extract` routes to `regex`; everything else defaults to LLM-judge with a deterministic rubric. -- **`soup eval discover `** runs farthest-first Jaccard clustering and emits a `CanarySet` with three groups: `held_out` (cluster representatives — tests generalisation), `adjacent_skills` (rare clusters — catches catastrophic forgetting), and `memorization_probes` (25 %-prefix truncations — catches verbatim regurgitation). -- **`soup eval lock `** canonicalises the suite (sorted-key JSON, no whitespace), computes a SHA-256 over the bytes that hit disk, and optionally attaches the artifact to a Registry entry as `eval_suite`. Two designs hash identically iff their semantic content matches. -- **`soup eval coverage --task `** does a heuristic gap analysis against the v0.54.0 task taxonomy: `reasoning` benefits from a `rlvr` dimension, `format_conversion` benefits from both `regex` and `rlvr`, etc. Missing scorers surface as named recommendations. -- **`soup eval gate-install --baseline `** writes a portable pre-push git hook that calls `soup eval --against ` and blocks the push when any of `{task accuracy, refusal rate, format validity, p95 latency}` regresses past its tolerance. Threshold checks use paired-bootstrap 95 % CI so a single outlier row doesn't flip the gate. Shell quoting via `shlex.quote` — no injection surface from a crafted run id or suite path. -- **Why blue-ocean.** Eval-authoring is conspicuously absent across Unsloth / LF / Axolotl — they're adding more benchmarks, going the opposite direction. Braintrust's golden-set pattern is SaaS-only because their economics need seat lock-in. TRL ships `compute_metrics` and stops; eval CI is "the user's problem" per torchtune's stated design. -- **+105 net new tests** (8571 → 8676) across `test_v0550.py` + `test_v0550_followups.py` covering all 4 Parts plus a `soup eval against` run-vs-run paired-bootstrap path AND 4-agent review-fix coverage (python / security / code / tdd): `MappingProxyType` immutability on every registry, `frozenset` for `SCORER_TYPES`, `FrozenInstanceError` on every public dataclass, `os.lstat + S_ISLNK` symlink reject on every atomic-write + read surface, `shlex.quote` for shell-script generation, exact-boundary tests on `n_samples` / `ci_level` / `per_cluster`, paired-bootstrap CI for regression decisions, and quadratic-DoS subsample cap inside the clustering hot path. +- **`soup diagnose `** scores six failure modes — `forgetting` (Δ accuracy vs base), `refusal` (advbench / xstest delta), `format` (JSON / regex / tool-call validity), `mode_collapse` (pairwise diversity at T=0 and T=1), `memorization` (training-prefix echo on partial-prompt probes), `contamination` (training-row overlap with public benchmarks) — and emits an overall OK / MINOR / MAJOR verdict using the same taxonomy as v0.26 Quant-Lobotomy. +- **`soup diagnose --badge diag.svg`** renders a self-contained 6-cell SVG report card with the overall verdict pill — embeddable in HF model cards and Twitter posts. Every user-controlled string passes through `html.escape`; no JS, no external deps. +- **`soup diagnose --evidence ev.json --output diag.json --attach-to-registry `** persists the report as a `diagnose_report` artifact on the v0.26 Model Registry — the first-class kind alongside `eval_suite` / `canaries` / `tensorrt`. +- **`soup train --diagnose-gate `** refuses to mark a run successful when any mode comes back MAJOR. Composes with v0.26 `--gate` and v0.55 `eval gate-install` for a three-layer safety net: training process anomalies (v0.34 `soup why`) → eval regression vs baseline (v0.55 gate) → model-behaviour failure modes (v0.56 diagnose). +- **Why blue-ocean.** Trainer libs ship code, not interpretability. TRL's v1 RFC narrows public surface — failure analysis falls below the cut. Eval SaaS (Braintrust, LangSmith) treat fine-tuning as <5 % of workload. The failure-mode taxonomy lives in academic papers with no implementation owner.
