Full history: [GitHub Releases](https://github.com/MakazhanAlpamys/Soup/releases). -**v0.59.0 — Governance & Provenance: every Soup run is procurement-ready.** ML-BOMs, SLSA-3 attestations, EU AI Act Annex XI/XII auto-docs, HIPAA/SOC2 audit log, SR 11-7 reproducibility receipts. The compliance story no SaaS can tell because the operator is the only one who sees weights, dataset, eval, and cost together. v0.59 is pure orchestration on top of v0.26 Registry + v0.34 cost tracker + v0.56 diagnose — no new training code, just structured exporters that emit the formats procurement demands. +**v0.60.0 — Supply Chain Security: tensors you can ship through procurement.** Six controls that hosted vendors structurally can't provide — adapter weight-space backdoor scanner, Merkle-root sign + verify, strict-safetensors mode (refuse pickle weights), trust-on-first-use namespace pinning (anti-AI-Jacking), closed license-compatibility matrix at merge, and a signed airgap-bundle for data-diode transfer. Every piece is opt-in for operators who want enforcement; CI pipelines and security-conscious enterprises get a "you can't ship an unaudited adapter through Soup" guarantee. -- **`soup bom emit --format cyclonedx|spdx|both`** — CycloneDX 1.6 ML-BOM + SPDX 2.3 + AI-profile dual emitter from any `RegistryEntry`. Includes base-model SHA, config SHA, data SHA, parent lineage, license-chain (SPDX id), and SLSA-style material list. Atomic write under cwd containment + `os.lstat` symlink rejection (TOCTOU-safe, mirrors v0.33.0 #22). -- **`soup attest emit --stage train --subject --sha <64hex>`** — in-toto v1 Statement wrapping a SLSA-3 provenance v1 predicate. Stage allowlist (`extract` / `train` / `eval` / `export` / `publish`). Sigstore + ed25519 signing live in v0.59.1; the schema + atomic-write surface ships now so CI can integrate. -- **`soup train --annex-xi `** — EU AI Act Annex XI Section 1+2 (technical documentation) + Annex XII (Article 53(1)(d) public training summary) markdown renderer. Top-10 domains, modality breakdown, FLOPs / kWh / CO₂ footprint. Markdown-active chars in operator-controlled fields (`model_name`, `base_model`, `dataset_summary`, domain names) escape `|[](){}!<>` plus newlines to defend against forged-heading / Markdown-link injection (mirrors v0.29.0 model-card v2 escape). -- **`soup audit-log tail / rotate`** — append-only JSONL audit at `~/.soup/audit.jsonl` (override via `SOUP_AUDIT_LOG_PATH`, containment-checked to `$HOME / $CWD / $TMPDIR`). Splunk/ELK ingestion-ready. PII redaction across every string field via the v0.40.3 `_SECRET_RE` policy (`hf_*` / `sk-*` / `Bearer …` → ``). POSIX `O_NOFOLLOW` + `0o600` perms; rotation at 100 MiB with symlink rejection at the backup path. -- **`soup train --repro-receipt `** — SR 11-7-style reproducibility receipt: seeds (torch / numpy / python), Python version, OS + arch, Soup version, kernel versions (CUDA / cuDNN / NCCL — best-effort from torch when available), GPU model + driver. Atomic write, cwd-contained. -- **CO₂ + energy schema (Part F).** `EnergyMeasurement` frozen dataclass with PUE adjustment, electricityMap SSRF-hardened endpoint validator (scheme allowlist + loopback-only HTTP + private-IP rejection — full parity with v0.51.0 `validate_hub_endpoint`). CodeCarbon hook lands in v0.59.1. -- **Shared `atomic_write_text` helper.** All four v0.59 atomic writes (BOM / attest / Annex / repro) and any future write that needs the TOCTOU defence now go through one `paths.atomic_write_text` — single-source-of-truth so a future contributor cannot accidentally drop the symlink check (mirrors v0.40.6 / v0.53.5 `peft_wiring` centralisation policy). -- **+99 new tests** (9193 → 9294).

(#11 OOM hint) `format_friendly_error` upgrades the CUDA-OOM and `OutOfMemoryError` patterns to point users at the explicit `--batch-size ` / `--grad-accum ` CLI flags before the legacy `quantization: 4bit` fallback — closes #11 with no functional change to the security surface. (#122 FlashAttention v3 incompatibility) New `soup_cli/utils/flash_attn.is_flash_attn_v3_available() -> bool` is a defensive probe (never raises, False on missing `flash_attn` / non-string `__version__` / unparseable / major < 3). `validate_longlora_compat` calls it AFTER the existing task / backend / architecture / ring-attention checks so the FA-v3 error only surfaces on otherwise-valid LongLoRA configs (avoids spurious confusion on unrelated misconfig). The check is loaded via a function-scoped import to keep `validate_longlora_compat` import-cheap and avoid CUDA-side effects at config load time on machines without `flash_attn` installed. (#120 LongLoRA arch allowlist) `soup_cli/utils/longlora.py` ships three new word-boundary regex helpers (`is_mistral_model`, `is_qwen_model`, `is_phi_model`) — same regex policy as v0.39.0 `is_gemma4_model` (rejects substring matches like `"my-mistralish-finetune"` or `"unmistral-7b"`). Shared `_check_model_name` input guard rejects `bool` BEFORE the `isinstance(str)` check (because bool is a subclass of int and would otherwise fall through silently — matches v0.53.3 `is_known_vlm_base` policy), rejects null bytes via explicit substring check, and returns `None` (→ helper returns False) for inputs >512 chars (avoids ReDoS-style overhead on adversarial input). New `is_supported_longlora_arch(model_name: object) -> bool` is the union accessor with defensive non-string surface (returns False rather than propagating TypeError, matches v0.53.3 / v0.52.0 model-detection policy). `validate_longlora_compat` also gained per-call null-byte rejection + bool/non-string TypeError on `task` and `backend` (matches v0.50.0 `validate_long_context_grpo_compat`); new `_truncate_for_message(value, limit=64)` helper bounds the `base` echo in error messages (security-review MEDIUM fix mirroring v0.53.3 `validate_vision_grpo_compat` redaction — defends against adversarial / long bases bloating stderr + log files). Mixtral is INTENTIONALLY excluded from the allowlist — regex matches `mistral` as a word-boundary token, NOT `mixtral`; documented at the docstring so a future contributor adding Mixtral support adds it explicitly. (#121 Llama 3.1 RoPE auto-detect) `apply_long_context_config` extended with `rope_scaling_type=None` auto-detect path — reads `model_config.rope_scaling` and runs `detect_llama3_rope_in_config` (v0.49.0 Part D helper) on it. If the existing block declares `llama3` (either via the legacy `type` key OR the newer `rope_type` alias), the auto-detect picks `"llama3"` + the upstream `LLAMA3_DEFAULT_*` constants; otherwise falls back to `"dynamic"`. Explicit caller pick still wins (any non-None value). Back-compat preserved by keeping the legacy default kwarg `rope_scaling_type="dynamic"`. The detect helper rejects non-Mapping config input via `TypeError` (no SSRF / file-read risk — the function is pure-Python data inspection). (#83 LLaMA Pro live block expansion) `soup_cli/utils/block_expansion.expand_model_blocks` lifts the v0.41.0 Part C `NotImplementedError` stub with a real implementation: clones the last `min(num_new_blocks, original_count)` decoder blocks via `copy.deepcopy` (full independent storage — no shared buffers), zero-inits each clone's residual projections (`mlp.down_proj.weight + bias` and `self_attn.o_proj.weight + bias`) so the appended block initially acts as identity per the LLaMA Pro paper §3.1, appends to `model.model.layers`, and updates `model.config.num_hidden_layers`. Validates `num_new_blocks` via `validate_expand_layers` (bool-guard + `[1, 64]`) BEFORE any model mutation. `_get_layers_module` uses explicit `is None` check (not falsy shortcut) to defend against `nn.Module.__bool__` overrides on subclasses (code-review HIGH fix). `_zero_init_block_residual` returns `bool` and the caller emits `warnings.warn` when neither standard projection path matches the cloned block (non-Llama-shaped arch — security-review LOW fix surfaces silent-degradation to operators training on Falcon-style models). Over-expansion silently clamps to `min(n, original_count)` rather than raising — matches the project's defensive-fallback policy for advisory operations. New `apply_llama_pro_freeze(model, num_new_blocks) -> int` is the canonical "train only new blocks" companion (global `requires_grad=False` pass, then unfreeze the tail N blocks; returns trainable parameter count). New shared helper `apply_block_expansion_if_configured(model, tcfg, console)` centralises the "if `expand_layers` is set, expand + optionally freeze + print" sequence — used identically by SFT and Pretrain trainers (matches v0.40.6 `peft_wiring` centralisation policy; defends against drift between trainer call sites which would otherwise produce subtle inconsistent behaviour). (#74 HF push surface QA) Manual QA of `soup push`, `soup train --push-as`, `soup data push`, `soup deploy hf-space` deferred to a contributor with private HF credentials — entry recorded in `tests/qa/v053_qa.md` with the full test plan + acceptance criteria. The HF push security surface (repo_id validation, token resolution, commit message sanitization, model card injection defence, Space template containment) is unchanged from v0.29.0 / v0.40.2 and remains covered by `test_hf_integration.py` + `test_v0402_part_a.py`. Test surface: 1 new test file (`tests/test_v0534.py`) carrying 49 new tests + 7 net updates to v0.49.0 / v0.41.0 / v0.10.x regression tests. Known limitations: (1) LongLoRA S² forward override still deferred to v0.49.1 — schema gate hardened, live monkeypatch is the next deliverable. (2) Mixtral excluded from LongLoRA allowlist (MoE attention forward signature differs). (3) Block-expansion zero-init covers Llama-shaped blocks only — non-standard arches still get appended + trainable, but lose the LLaMA Pro identity-init guarantee (and emit a runtime warning). (4) Llama 3.1 RoPE auto-detect only fires when caller passes `rope_scaling_type=None` (explicit pick wins). (5) #74 live QA against a private HF repo is the v0.53.5+ follow-up. (v0.53.4) - **v0.53.3 — GRPO Plus partial wiring (#128 grpo_fp16, #129 vision-VLM probe)**: lifts two surgical v0.50.0 GRPO Plus deferred stubs while keeping the project's hardening invariants; the four larger items (#127 stability callback, #123 6 GRPO variant loss kernels, #126 PRMTrainerWrapper, #68 multi-objective preference live combine) are scope-deferred to v0.53.4. (#128 grpo_fp16 routing) New `_validate_grpo_fp16_amp_exclusive` SoupConfig cross-validator rejects the silent-mutex combo `grpo_fp16=True + auto_mixed_precision=True` at config load — both flags pick the mixed-precision dtype via different codepaths; combining them is a footgun where downstream behaviour depends on validator execution order. Cross-validator short-circuits when `task != 'grpo'` so the v0.50.0 stability task-gate diagnosis fires first (keeps the most actionable error at the front; code-review HIGH fix). New `GRPOTrainerWrapper._build_precision_kwargs(self) -> dict[str, bool]` returns the `{fp16, bf16}` HF kwargs per `(device, grpo_fp16)` matrix: non-CUDA (CPU / MPS / XPU) → both False (HF Trainer's fp16/bf16 kwargs are CUDA-specific, MPS / XPU use their own mixed-precision paths), CUDA + `grpo_fp16=True` → `fp16=True, bf16=False` (unsloth parity), default CUDA → `fp16=False, bf16=True` (legacy v0.50.0 path). Direct attribute access on `self.config.training.grpo_fp16` (no `getattr` fallback — Pydantic-guaranteed field). (#129 vision-GRPO base probe) New `soup_cli/utils/prm.KNOWN_VLM_REGEX` compiled regex with 10 word-boundary alternatives covering Qwen2-VL / Qwen2.5-VL / QVQ / Pixtral / InternVL / InternVL2_5 / InternVL3 / Llama-3.2-Vision (any size via `[a-z0-9._-]*vision` glob) / LLaVA / MiniCPM-V / Idefics / ShareGPT4V / Fuyu. Word-boundary idiom `(?:^|[^a-z0-9])…(?:[^a-z0-9]|$)` mirrors v0.39.0 `is_gemma4_model` / v0.44.0 `is_llama4_model` / v0.49.0 `is_llama_model` policy — rejects substring noise like `"my-pixtralish"`. New `is_known_vlm_base(name: object) -> bool` is defensive — returns False (never raises) on non-string / bool / empty / null-byte / `>_MAX_BASE_NAME_LEN=512`. Extended `validate_vision_grpo_compat` with optional `base: str | None = None` kwarg — `None` / empty-string skips the probe (back-compat for legacy v0.50.0 Part E callers); non-empty-non-VLM raises `ValueError` with friendly message naming the expected families (Qwen2-VL / Pixtral / InternVL / Llama-3.2-Vision / LLaVA / MiniCPM-V). Error message **truncates the echoed `base` to 64 chars** before serialisation (security-review MEDIUM fix mirroring v0.34.0 `crash.py` `output_dir` basename policy — defends against adversarial / long bases bloating error logs and from leaking unredacted user input into operator-facing tracebacks). `_validate_vision_grpo` in SoupConfig threads `base=self.base` so a YAML pairing `vision_grpo: true` with a non-VLM checkpoint is rejected at schema-load instead of surfacing as a cryptic `"module has no attribute 'vision_tower'"` runtime error. Test surface: 1 new test file (`test_v0533.py`) carrying 37 new tests covering: every `_build_precision_kwargs` matrix cell (CUDA + grpo_fp16 / default CUDA / CPU / MPS), every cross-validator branch (mutex rejection / task-gate priority / both-off pass), every regex alternative (Qwen2-VL / Pixtral / QVQ / Llama-3.2-Vision variants / negative matches), every defensive guard (bool / non-string / null-byte / 512-byte boundary), error-message truncation (security-review M regression), and end-to-end YAML load (happy + reject). Known limitations: (1) Scope-deferred — 4 larger v0.53.3 items moved to v0.53.4 because each requires deep TRL subclassing and warrants its own focused release; the v0.40.x stub-then-live cadence shipped 5 patch releases over 6 weeks, mirroring that here. (2) VLM allowlist is static name-regex only; a legitimate VLM published under an org whose checkpoint name lacks any of those tokens (e.g. a custom internal fork) is rejected at schema-load and operators must omit `vision_grpo: true` until a future release adds a runtime `model.config.vision_config` probe. (3) `_build_precision_kwargs` is GRPO-only — other RL trainers (PPO / RewardModel) follow their existing mixed-precision conventions. (v0.53.3) +- **v0.60.0 — Supply Chain Security**: 6 parts ship `soup adapters scan / sign / verify / check-safetensors`, namespace-pin TOFU SQLite, license-conflict matrix at merge, and `soup airgap-bundle`. **Merkle-root manifest is recursive** (review-fix HIGH) — `_enumerate_files` walks subdirs so nested `tokenizer/` / `processor/` files are signed; symlinked subdirs and files refused loudly via `os.lstat + S_ISLNK`; per-file realpath+commonpath check defends against hardlinks pointing outside the adapter dir. **`adapter_sign._load_signature` TOCTOU-hardened** — direct `os.lstat` then-open (no `isfile`-then-`open` race); explicit `S_ISLNK` and `S_ISREG` checks. **16 MiB cap on `.soup-signature.json`** prevents OOM on a crafted multi-GiB JSON. **`NamespacePinStore` containment** — public constructor refuses paths outside `$HOME / $CWD / $TMPDIR` (review-fix HIGH); SQLite path symlink-rejected before `sqlite3.connect`; POSIX `0o600` perms; `SOUP_NAMESPACE_PIN_DB` env override containment-checked. **Datetime parsing for backward-jump detection** — uses `datetime.fromisoformat` rather than lexicographic compare so non-UTC offsets decide correctly (python-review MEDIUM fix). **`allow_namespace_shift` bool rejected** (security-review CRITICAL idiom) — prevents `--allow-namespace-shift true` from becoming a free-for-all bypass. **Author override case-insensitive** so legitimate operator typing mismatch case doesn't fail the gate, but the case sensitivity is bounded to author normalization only. **`airgap_bundle` TOCTOU re-check** — `os.lstat + S_ISLNK` on parent dir AND final output path BEFORE `mkstemp` (review-fix HIGH); `os.path.realpath` (not `abspath`) for Windows 8.3 short-name safety; `os.path.lexists` (not `exists`) in tmpfile cleanup so a hostile symlink swap can't trick the unlink. **64 MiB manifest cap on inspect**; **`tarfile.data_filter`** set on the TarFile instance for any future `extractall` caller. **Deterministic dataset labeling** — sorted basename (not argv index) so reorderings produce identical manifests, fulfilling the "same inputs → same SHA-256 list" contract (review-fix HIGH). **License matrix**: closed allowlist of 33 SPDX-ish ids; conservative-by-design — when in doubt, flag; `--license-override ` requires 8-char minimum to defend against `--license-override y` style bypass; reason capped at 4096 chars; null-byte rejected; TypeError on non-string (review-fix LOW for consistency with project policy). **`UNSAFE_EXTENSIONS` frozenset (8 entries)** locks the pickle-rejection allowlist behind `MappingProxyType`-style immutability; static-extension check is intentional (operators wanting protection against `evil.safetensors` containing actual pickle bytes should also enable v0.60.x magic-byte check, deferred). **`adapter_scan` thresholds** tuned against synthetic rank-1 trojans (`_RANK1_DOMINANCE_FAIL=200x`, `_ENERGY_TOP1_FAIL=0.95`, `_FROB_OUTLIER_FAIL_SIGMA=8.0`) with conservative-by-design false-positive bias; bool-as-int rejection on `ScanFinding.value` / `threshold`; non-finite values rejected. **Test count**: 9294 → 9446 (+143 net in `tests/test_v0600_part_{a-f}.py`; ~140 pass + 6 POSIX-only symlink tests skipped on Windows). **Known limitations**: (1) **Sigstore + ed25519 signing deferred to v0.60.1** — `UNSIGNED` backend live (offline Merkle-root tamper detection); the live signers raise `NotImplementedError` with explicit v0.60.1 marker (stub-then-live pattern, same as v0.59.0 attest). (2) **Namespace-pin not wired into HF download path** — helpers ship live but the integration into `utils/hubs.download_repo` lands in v0.60.1; operators can call `verify_namespace` manually via Python API today. (3) **License gate is opt-in** — `--license ` flag required to invoke the gate; auto-extraction from `adapter_config.json` / HF model-card metadata lands in v0.60.1. (4) **Airgap bundle does NOT yet auto-attach v0.59 repro-receipt** — train→bundle handoff wiring is v0.60.1. (5) **Strict-safetensors is extension-based only** — a pickle stream renamed to `.safetensors` bypasses the static scan; the actual safetensors loader will surface that loudly at load time, but magic-byte check is a v0.60.1 follow-up (`PK\x03\x04` / `\x80` pickle opcode detection on first 16 bytes). (6) **License override is NOT yet auto-emitted to audit-log** — v0.59 `audit_log.append_audit_event` integration lands in v0.60.1. (7) **NamespacePinStore SQLite is single-process** — concurrent `soup train` runs racing on the TOFU write may serialise via SQLite locking; WAL + cross-process file-lock tracked for v0.60.1. (8) **Adapter scan false-negative on multi-vector trojans** — sophisticated attacks distributing energy across many singular vectors will pass; per-arch threshold profiles tracked for v0.60.x. (9) **5-agent review wave: python-reviewer + general-purpose security + general-purpose code-review + general-purpose tdd-guide + manual smoke** (verification-loop). Direct `code-reviewer` / `security-reviewer` agent invocations hit context-window thrash on the 800+ KB CLAUDE.md release-notes history; the `general-purpose` agent with focused "do not crawl, read only these N files" prompts produced equivalent findings (matches v0.58.0 / v0.59.0 wave-3 idiom). (v0.60.0) + - **v0.59.0 — Governance & Provenance**: 6 parts ship `soup bom emit` (CycloneDX 1.6 ML-BOM + SPDX 2.3 + AI profile dual emitter), `soup attest emit` (in-toto v1 + SLSA-3 provenance v1), `soup train --annex-xi` (EU AI Act Annex XI/XII markdown auto-doc), `soup audit-log tail/rotate` (HIPAA/SOC2 JSONL with PII redaction), `soup train --repro-receipt` (SR 11-7 receipt), CodeCarbon hook schema + electricityMap SSRF validator. **TOCTOU lstat-before-write** on every atomic-write surface — `paths.atomic_write_text` shared helper centralises the v0.33.0 #22 / v0.43.0 / v0.55.0 / v0.56.0 / v0.57.0 / v0.58.0 TOCTOU defence so a future contributor cannot accidentally drop the symlink check. **Audit log POSIX `O_NOFOLLOW`** on `os.open` + `0o600` perms + symlink rejection at the rotation backup path. **PII redaction across every string field** (command / args / host_id / operator_id) via the v0.40.3 `_SECRET_RE` policy. **`SOUP_AUDIT_LOG_PATH` env containment** to `$HOME / $CWD / $TMPDIR` (mirrors v0.36.0 `SOUP_BATCH_CACHE_PATH` policy). **`validate_electricity_map_endpoint` SSRF parity** with v0.51.0 `validate_hub_endpoint` — scheme allowlist, loopback-only HTTP, RFC1918 / link-local / reserved / multicast IP rejection via `ipaddress.ip_address`, control-char + null-byte rejection, `0.0.0.0` explicitly rejected, IPv6 brackets handled by `urlsplit.hostname` (no manual `strip("[]")`). **Markdown injection defence** — `_md_escape` in Annex XI/XII renderers neutralises `|[](){}!<>` plus newline / CR / tab in every operator-controlled field (model_name / base_model / dataset_summary / top-domain names / modalities), defending against forged-heading + Markdown-link injection in downstream PDF/HTML renderers (mirrors v0.29.0 model-card v2 escape policy). **In-toto subject SHA-256 locked to 64-hex** via regex; **stage allowlist** `extract / train / eval / export / publish`; **builder_id capped at 256 chars** + null-byte rejected; **invocation_id capped at 256 chars** before JSON serialisation. **Test count**: 9193 → 9294 (+99 net in `tests/test_v0590.py`; 93 pass + 6 POSIX-only symlink tests skipped on Windows). **Known limitations**: (1) **Sigstore + ed25519 signing deferred to v0.59.1** — `UNSIGNED` backend live, `sigstore`/`ed25519` raise NotImplementedError with explicit v0.59.1 marker (stub-then-live pattern). (2) **Live CodeCarbon hook deferred to v0.59.1** — `measure_run_energy` returns None even with codecarbon installed; live `EmissionsTracker` lifecycle wiring inside trainer wrappers is the v0.59.1 deliverable. The SSRF-hardened endpoint validator ships now so v0.59.1 is purely additive. (3) **PDF rendering deferred to v0.59.1** — markdown body now; `reportlab` PDF integration later. (4) **Audit-log auto-instrumentation NOT shipped** — every command does NOT yet auto-emit one line via the Typer top-level callback; only the reader + write API ship live. (5) **Top-10 domain analysis NOT auto-populated** — `AnnexXIData.top_domains` accepts an operator-supplied tuple but the train-flag wiring currently passes empty. (6) **Annex XI / repro-receipt flags only fire on `LOCAL_RANK=0`** — single-node multi-GPU correct; multi-node `RANK`-aware guard tracked separately. (7) **Three review waves: python-reviewer + general-purpose security + general-purpose code-review + general-purpose tdd-guide.** verification-loop done manually via CPU smoke (`soup bom emit` / `soup attest emit` / `soup audit-log tail` / `soup train --help` shows `--annex-xi` + `--repro-receipt`; happy + failure modes all exercised). The direct `code-reviewer` / `security-reviewer` agent invocations hit context-window thrash on the full repo; the `general-purpose` agent with focused "do not crawl, read only these 9 files" prompts produced equivalent findings (matches the v0.58.0 wave-3 idiom). (v0.59.0) - **v0.58.0 — `soup loop` data flywheel capstone**: 4 Parts ship `loop init / status / pause / resume / watch / canary / replay`. Three review waves fixed 1 CRITICAL + 7 HIGH + 9 MEDIUM + 2 LOW total before tag (python-review wave 1: BucketStats lock scope + TOCTOU + NUL-byte; code-review wave 2: watch-preserves-paused / budget-skip-no-manifest / canary-autoroll-persisted / `route()` math.ceil / `parse_budget("usd")` friendly error / `list_iterations` OSError swallow / module-top `replace`; security + tdd wave 3: `_check_dir` TOCTOU + boundary tests at `_MAX_STR_FIELD=512` and `_MAX_FILE_BYTES=1 MiB` + bool-rejection on `iteration_count` / `runs_today` / `monthly_budget_usd` / `spent_this_month_usd` + empty-string rejection on `canary_active` / `last_iteration_id` / `last_run_date`). **TOCTOU lstat-before-write** — `_check_path` and `init_state` use direct `os.lstat` (catching `FileNotFoundError` for the missing-file branch) instead of the `lexists` + `lstat` two-step that opens a race window; matches v0.33.0 #22 / v0.43.0 / v0.55.0 policy. **NUL-byte rejection on `_bucket_for_key`** — defence-in-depth on the SHA-256 input even though the request_key is internally-derived. **`BucketStats._lock` `compare=False`** — `threading.Lock` instances have no value-equality so the auto-`__eq__` would never return True; flag added per python-review MEDIUM. **`canary` command reloads after write** so the in-memory `LoopState` reflects the persisted `updated_at` (matches every other persist-then-read CLI in the project). **Atomic state-file writes via `tempfile.mkstemp + os.replace`** with POSIX `0o600` perms after rename (mirrors v0.26.0 registry.db policy). **1 MiB cap on the loop.yaml state file**; bool-as-int rejection on every numeric (matches v0.30.0 `Candidate` / v0.34.0 `estimate_run_cost_usd` policy); NUL-byte + oversize rejection on every string. **`subprocess.Popen` argv-list (no shell)** for `loop watch --detach`; `# noqa: S603` annotation documents the bandit suppression. **`CanaryPolicy` cross-field validation**: empty stable rejected, `canary == stable` rejected, traffic_pct ∈ [0, 100] with `math.isfinite` (NaN/Inf rejected), traffic without canary rejected, `sticky_on_rollback` must be `bool`. **Sticky-on-rollback policy** — a flaky verdict cannot ping-pong traffic between adapters; the operator must explicitly re-promote a canary after rollback (matches the v0.26.0 Quant-Lobotomy "no silent recovery" surface). **Test count**: 8998 → 9193 (+195 net in `tests/test_v0580.py`; 188 pass + 1 POSIX-only symlink test skipped on Windows). **Known limitations**: (1) **Stage callbacks ship as no-op stubs** — production wiring (v0.26 trace-to-pref + eval-gate + v0.30 multi-adapter deploy) is operator-driven via `WatchConfig` to keep the import graph one-directional; pre-wired versions tracked for v0.58.1. (2) **Soup Can per-iteration packaging deferred to v0.58.1** — iteration manifests under `.soup-loops//iteration.json` are laid out so a v0.26 Soup Can wrapper hook can ship without re-shaping files, but the Registry-DAG append is the v0.58.1 deliverable. (3) **`--detach` is a single-process subprocess** — no `setsid` / nohup-style daemonization. Operators on Linux should pair with `systemd` or `tmux`; on Windows the subprocess survives the parent CLI exit. (4) **No automatic budget refill on UTC month rollover** — `spent_this_month_usd` is reset by the operator (or by writing a fresh `loop.yaml`); the daemon does not auto-detect month boundaries. (5) **Full 5-agent review wave completed across 3 sequential rounds.** The direct `code-reviewer` / `security-reviewer` agent invocations hit context-window thrash on the full repo (the 800+ KB release-notes history blew their context); the `general-purpose` agent with focused "do not crawl, read only these 7 files" prompts produced equivalent findings. verification-loop completed via manual CPU smoke covering init / status / pause / resume / watch --max-iterations / canary / replay end-to-end. All 188 of 189 tests pass (1 POSIX-only symlink test skipped on Windows); subprocess uses argv list, all paths cwd-contained + symlink-rejected, no top-level torch imports in any loop module.
