Full history: [GitHub Releases](https://github.com/MakazhanAlpamys/Soup/releases). -**v0.64.0 — Pre-flight & Tooling: pick the right base, lock the env, refuse OOMs before launch.** Closes axis 1 + axis 11 of the roadmap. Six new top-level commands give operators the rest of the pre-flight surface that v0.54 `soup advise` started: which base model, which compute, which env, which licence. Hosted vendors push their own catalogs and skip CUDA-hell ownership — Soup is local + spans every base. +**v0.65.0 — Eval Depth: calibrated judges, behaviour batteries, capability auto-suite, CheckList DSL, IRT subset selector.** Five new commands close axis 4 of the roadmap — evals as a first-class surface, not an afterthought. SaaS evals (Galileo, Braintrust) ship judges but not calibration; lm-eval-harness is the closest to capability auto-suite but wiring is painful; CheckList for LLMs hasn't been revived. Soup ships all five locally. -- **`soup tunability --dataset [--candidates a,b,c] [--probe-steps N]`.** Probe-train 8 small candidate bases (Qwen3-0.6/1.7B, Llama-3.2-1/3B, Gemma-3-E2B, Phi-4-mini, SmolLM3, Qwen2.5-1.5B) against a held-out slice and report the (delta-from-base × cost × license) Pareto frontier. `--plan-only` dry-runs the sweep; `--list` shows the built-in catalogue. Live LoRA probe deferred to v0.64.1 — v0.64.0 ships the schema, Pareto math, default catalogue, and a `probe_fn` injection point. -- **`soup plan --config soup.yaml` / `soup apply --config soup.yaml`.** Terraform-shape lock-and-execute for training. `plan` writes `soup.tfstate` with the run's config SHA, dataset SHA, estimated cost, ETA, peak VRAM, and spot price. `apply` refuses if the YAML drifted from the state (exit 3) so you never silently re-spend $0.50 on a mutated config. `--dry-run` validates without running. -- **`soup env lock` / `soup env status` / `soup env check`.** Hermetic env lockfile via `importlib.metadata` — torch / transformers / peft / trl / accelerate / bitsandbytes / flash-attn / xformers / deepspeed / unsloth / vllm + Python + platform + CUDA versions. `check` compares the current env against the lock and exits 3 on ABI-sensitive drift (the "FT worked on Friday, broke on Monday" problem). -- **Hardware-fit calculator.** Static analytical predictor of peak VRAM by class (weights / optimizer / gradients / activations / overhead). Given (params, seq_len, batch_size, optimizer, quant, peft, gradient_checkpointing), it returns a 5-bucket breakdown + an OK/OOM verdict with 10% safety margin and an actionable hint (`--batch-size halve` / `--quantization 4bit` / `--gradient-checkpointing auto`). Composes with v0.40.3 live CUDA OOM probe. -- **`soup completions bash | zsh | fish`.** Sourceable shell completion scripts. `eval "$(soup completions bash)"` adds tab-completion for `soup` + every subcommand in the current shell. `--target-modules` falls back to canonical Llama-shape defaults; recipe names auto-complete from the 115+ catalogue. -- **`soup license-advisor --target b2c|defense|embedded [--license --mau N]`.** Per-deploy-target license matrix. B2C → permissive recommended, non-commercial forbidden. Defense → restricted-use community licenses (Llama / Gemma / Qwen-research / Mistral-research) forbidden because their acceptable-use clauses clash. Embedded → strong-copyleft (GPL/AGPL) forbidden because closed-source firmware redistribution. The per-license check flags the Llama community license + > 700M MAU rule (exit 3) so you don't ship a B2C product that needs a separate Meta licence after the fact. Composes with v0.60 `adapters merge` license-conflict gate. -- **+271 new tests** (10035 → 10306 net).

Manual CPU smokes for every Part A-F command incl. failure modes (drift exit 3, license block exit 3, completions unknown shell exit 2). +- **Judge calibration with conformal abstention** — `eval/calibrate.py` extended with SCOPE/CJE-style bidirectional pairwise judging. `PairwiseJudgement` carries the first-position + second-position + oracle verdicts for one prompt; `fit_position_bias` returns a coefficient ∈ [-1, 1] measuring slot-flipping; `conformal_threshold(scores, *, alpha)` emits the α-quantile abstention threshold; `run_pairwise_calibration` runs the full fit; `ensure_judge_calibrated(report)` is the production gate that **refuses** to score with an uncalibrated judge (`RuntimeError` on missing report / low agreement / extreme bias). v0.43.0 KL-divergence surface preserved. +- **`soup eval behavior --battery xstest|harmbench|jailbreakbench|elephant|syceval`.** Bundled behaviour battery with pre/post diff in one report. 5 tiny probe sets ship under `soup_cli/data/_fixtures/behavior/` (harmful prompts redacted — operators pull the real sets from upstream papers); word-boundary regex agreement (rejects `"safe" in "unsafe"` false positives; accepts `"safe."`). OK/MINOR/MAJOR thresholds match v0.26 / v0.56 taxonomy. Composes with `soup diagnose` for a fuller report card. +- **`soup eval capability --suite full|fast|math|code`.** Pre-bundled capability profile selector over MMLU-Pro / GPQA / BBEH / AIME / MATH-500 / HumanEval+ / SWE-bench-Verified with sane `lm-eval-harness` task ids. `fast` = (mmlu-pro, humaneval-plus); `math` = (aime, math-500); `code` = (humaneval-plus, swe-bench-verified). Emits the (benchmark, lm-eval task) manifest for downstream `soup eval benchmark` chaining. +- **`soup eval checklist [--evidence ]`.** Ribeiro et al. 2020 CheckList behavioural DSL. Three test kinds — `mft` (Minimum Functionality Test: response must contain a keyword as a whole WORD), `inv` (Invariance: all paraphrases get the same answer), `dir` (Directional Expectation: response shifts under a perturbation). YAML spec format; per-test OK/MINOR/MAJOR verdict; neutral OK when evidence absent (matches v0.56 / v0.61 policy). +- **`soup eval irt-subset --size full|small|tiny`.** Item Response Theory eval-cost optimizer. 1PL Rasch model closed-form fit (`β̂_i = -log(p̂_i / (1 - p̂_i))`); picks high-info items (`p̂(1-p̂)` is maximised at 50/50 questions); `tiny` keeps 10%, `small` keeps 30%, `full` keeps 100%. 5-10x cut in eval bills without losing ranking power.

(2) `soup apply` does NOT execute `soup train` in-process — prints the canonical invocation; Typer commands aren't safe to re-enter. (3) `soup env` does NOT recreate a venv — schema + drift detection ship; `--fix` action is v0.64.1. (4) Hardware-fit is analytical only — composes with v0.40.3 live CUDA probe but does NOT replace it. (5) `complete_target_modules` returns canonical Llama defaults — live HF-config introspection is v0.64.1. (6) License advisor takes the license id from the operator — no model-card scraping. (7) Deploy targets are a 3-entry allowlist (b2c/defense/embedded). (8) `compute_dataset_sha` returns zero-hash for outside-cwd paths rather than raising so `soup plan` runs before the dataset exists. (v0.64.0) - **v0.63.0 — Production Trace Ecosystem**: 5 LIVE parts ship `soup ingest` (Langfuse / LangSmith / Helicone / OpenPipe / OTel / OpenAI Stored Completions) + `soup prune-prompt` + `soup data active-sample` + `soup ab` (Wald sequential SPRT) + `soup drift-alarm` (rolling KL + SSRF-hardened webhook). **Soup never makes the SaaS network call** — `soup ingest` parses JSONL exports the operator pulls from their dashboard; zero credential-handling threat surface. **`validate_webhook_url` SSRF parity with v0.51.0 / v0.30.0 OTLP**: scheme allowlist `{http, https}`, null-byte + control-char rejection (CRLF-injection defence), `0.0.0.0` explicitly rejected, plain HTTP only for loopback hosts (`localhost` / `127.0.0.1` / `::1`), RFC1918 / link-local / reserved / multicast IPs rejected via `ipaddress.ip_address`. **`post_webhook` never crashes drift check** — broad `except Exception` (with `# noqa: BLE001`) so telemetry/alerting failure cannot mask a real drift verdict. **Closed-allowlist validators**: `SUPPORTED_INGEST_SOURCES = {langfuse, langsmith, helicone, openpipe, otel, openai-stored}`, `SUPPORTED_METRICS = {latency, judge_score, retry_rate}` (mSPRT) — both bool-first / null-byte / oversize (≤32-char) / case-insensitive normalisation. **`TraceRecord.metadata` is `MappingProxyType`-wrapped post-init** (`__post_init__` via `object.__setattr__` because the dataclass is frozen) so a returned record cannot be mutated by callers (code-review MEDIUM fix v0.63.0). **DoS caps**: `_MAX_INGEST_LINES=1_000_000` on JSONL ingest, `_MAX_SCAN_ROWS=100_000` + `_MAX_ROW_CHARS=1_000_000` on `prune-prompt`, `_MAX_BUDGET=100_000` on `active-sample`, `_MAX_SAMPLES_PER_ARM=1_000_000` on mSPRT, `_MAX_WEBHOOK_URL_LEN=4096` + `_MAX_TEXT_LEN=1_000_000` on drift. **Path containment** via shared `is_under_cwd` (project-standard `os.path.realpath + commonpath`, NOT `Path.resolve + relative_to`) — `ingest_traces` / `prune_traces` / `sample_uncertain_rows` / `run_msprt` / `run_drift_check` all enforce cwd + null-byte rejection BEFORE any open. **Rich markup escape** on every user-controlled string surfaced through `rich.markup.escape` (`--source` / `--metric` / `--logs` / error messages). **`detect_common_prefix` never early-exits on the 100% match** (code-review HIGH fix v0.63.0) — binary-search-over-templates finds the longest threshold-meeting prefix even when a 100% prefix exists shorter than a threshold-majority prefix. **`prune_traces` row-cap uses `break` not `pass`** (code-review HIGH fix v0.63.0 — earlier draft left the DoS cap unenforced). **mSPRT decision math is Wald's classic SPRT for the point alternative**: LLR is a martingale under H0 (E[exp(LLR_n)] = 1) so Type-I error is controlled at every stopping time per the optional stopping theorem. Earlier draft used a malformed mixture-prior LLR with the wrong sign on the log term — drove LLR positive under H0 as n grew, producing unbounded false-positive rate (code-review CRITICAL fix v0.63.0). **`_is_private_or_link_local` precedence parens** (code-review MEDIUM fix v0.63.0) — safety-critical SSRF gate, future edits should not need to re-derive Python operator precedence to verify the logic. **Auth env-var resolution is read-only** — `resolve_auth_env` looks up `LANGFUSE_KEY` / `LANGSMITH_API_KEY` / `HELICONE_API_KEY` / `OPENPIPE_API_KEY` / `OPENAI_API_KEY` / `OTEL_EXPORTER_OTLP_HEADERS` from `os.environ`; Soup itself never makes the network call. **Test count**: 9816 → 10035 (+219 net in `tests/test_v0630_part_{a-e}.py` + `tests/test_v0630_followups.py`). **Review-fix coverage across 2 reviewer waves** (code-reviewer + tdd-guide; python-reviewer + security-reviewer agents context-thrashed on the 800+ KB CLAUDE.md release-notes history — matches v0.58.0 / v0.59.0 / v0.60.0 / v0.61.0 / v0.62.0 idiom; verified manually): 1 CRITICAL (mSPRT sign error) + 2 HIGH (detect_common_prefix early-exit + `pass`→`break` DoS cap) + 3 MEDIUM (TraceRecord MappingProxyType + `_AUTH_ENV` dedup + drift_alarm precedence parens) + 2 LOW (pooled_se dead-branch + mean_uncertainty NaN guard) + 8 follow-up tests (boundaries + source-grep regression guards for no-heavy-top-level-imports across all 5 new util modules). **Known limitations**: (1) No live SaaS API pull — operators export from the vendor dashboard / SDK first, Soup parses the JSONL. (2) `prune-prompt` operates on raw characters not tokens — UTF-8 multi-byte sequences may be cut mid-codepoint at the threshold boundary. (3) Active-learning K>2 RMs deferred to v0.63.1 — 3+ RM scores fall back to `max - min` range. (4) mSPRT single-metric per pass — operators monitoring (latency, judge_score, retry_rate) jointly should adjust alpha via Bonferroni and run three passes. (5) mSPRT assumes Gaussian-like data — binary metrics must be pre-aggregated to per-prompt rates. (6) drift-alarm uses whitespace tokeniser — sub-word BPE-level drift invisible (tokenizer-aware variant tracked for v0.63.1). (7) `post_webhook` swallows every exception so telemetry can NEVER crash the drift run. (8) Zero-variance arms in mSPRT → `continue` forever (proper SPRT behaviour: with no observed noise the test cannot bound Type-I error honestly).
