For a legacy saved +``OnlineManager``, explicitly reconfigure or recreate each strategy, its +``strategy.tool``, and any delayed trainer after reviewing their artifact sources. +Changing only the strategy's flag does not update an already-created tool. An +example constructor's ``trusted_artifacts`` flag does not override a manager +subsequently loaded from disk; there is no global grant. + +These options authorize the necessary executable model, dataset and task artifact +reads, not all artifacts in a run.

Supported reconstruction cases include pickle +protocols 4 and 5, NumPy masked arrays, pandas nullable integer/float/boolean and +Python-backed string arrays, categorical data, datetime/timedelta data, supported +timezone metadata (such as UTC and ``pytz``), period and interval data, and sparse +arrays. + +This is not a guarantee for every NumPy or pandas object. Object-dtype cells, +custom subclasses, extension arrays and metadata can introduce additional classes. +Arrow-backed pandas data and ``zoneinfo.ZoneInfo``-backed timezone representations +are not supported by default. Whether a particular representation is used depends +on Python, NumPy and pandas versions and dtype settings. Regenerate such data using +supported representations in a trusted producer environment rather than enabling +unrestricted loading just to read predictions. + +Pickle's existing cross-version limitations still apply. Protocol support does not +guarantee compatibility between Python, NumPy, pandas or model-library versions, +nor does ``trusted=True`` fix missing or renamed classes. Preserve the producing +environment for legacy executable artifacts and test representative artifacts +before upgrading a workflow. + +HIST stock-index mapping +------------------------ + +HIST's bundled stock-index mapping is now +``examples/benchmarks/HIST/qlib_csi300_stock_index.json``, containing the same +735 entries. Update custom YAML ``task.model.kwargs.stock_index`` paths from +``qlib_csi300_stock_index.npy`` to the JSON file. The bundled workflow already uses +JSON; the separate numeric ``stock2concept`` matrix remains a ``.npy`` file. + +For a known-trusted custom mapping, re-export from the original trusted metadata or +producer into a JSON object with instrument strings as keys and non-negative integer +row indices as values. Preserve the correspondence with the ``stock2concept`` +matrix and keep indices within its row bounds. Merely renaming an object ``.npy`` +file does not convert it. Object-pickled ``.npy`` mappings are deliberately not +supported, and recorder consent does not re-enable them. See the +`HIST migration instructions `_. + +Custom recorders and loaders +---------------------------- + +Custom ``Recorder`` implementations should adopt +``load_object(self, name, *, trusted=False)``, validate boolean consent, enforce +restricted loading by default and allow unrestricted deserialization only with +explicit ``trusted=True``. Never ignore the flag or add an unsafe retry path. + +For compatibility, ``R.load_object(name)`` (and ``trusted=False``) delegates to a +legacy recorder's ``load_object(name)`` without adding a keyword.

artifact trust and publish upgrade guidance Use trusted consistently across public APIs and CLI options. Migrate pre-release saved consent only at serialization boundaries, reject invalid or conflicting settings, and preserve restricted data reads. Add a canonical upgrade guide with README, installation, changelog and runtime-error entry points. BREAKING CHANGE: executable artifact restoration requires explicit trusted=True. HIST mappings use JSON and high-frequency cache paths must remain within artifact_root. See docs/start/artifact_migration.rst for upgrading existing workflows.

Until the + first tagged release containing these changes, treat them as unreleased. + That release's versioned upgrade notes should link to this guide. + +What changes when upgrading +=========================== + +The built-in MLflow recorder now uses a restricted unpickler by default. Fresh +training and prediction using in-memory objects need no opt-in. Supported data-only +reads, including predictions, labels and numerical reports, also remain available +without consent. + +Saved models, datasets, meta-models and tasks containing executable objects such as +reweighters require explicit ``trusted=True`` when reloaded. Backtest artifacts +containing ``Position`` instances or indicator objects require the same decision; +they are not data-only reports. A ``.pkl`` suffix, a familiar artifact name or a +successful run does not establish safety. + +Before updating an existing workflow: + +1. Identify which loads read data and which restore executable objects. Leave + supported data-only reads restricted. +2. Verify both the artifact producer and storage write permissions before setting + ``trusted=True`` at each relevant workflow entry point (CLI: ``--trusted=True``). +3. Review separately saved workflow components, local caches and custom loaders + using the sections below. Update HIST mappings and high-frequency cache paths + where applicable. +4. Test representative artifacts in a compatible environment before deployment. + +Ordinary trusted model/dataset artifacts do not need deletion, conversion or a +full retrain merely to adopt explicit consent. Example ``main``/``first_run`` +methods can reset experiments and task pools; do not use them as migration +commands. Preserve existing results and use dedicated stores when trying examples. + +Single-object loads and trust boundaries +======================================== + +Keep data-only reads in the default mode: + +.. code-block:: python + + from qlib.workflow import R + + rec = R.get_recorder() # Select the intended run in your experiment. + predictions = rec.load_object("pred.pkl") + labels = R.load_object("label.pkl") + report = rec.load_object("portfolio_analysis/report_normal_1day.pkl") + +After verifying the writer and store, explicitly authorize executable objects: + +.. code-block:: python + + model = rec.load_object("params.pkl", trusted=True) + dataset = R.load_object("dataset", trusted=True) + positions = rec.load_object( + "portfolio_analysis/positions_normal_1day.pkl", trusted=True + ) + +``Recorder.load_object`` and ``R.load_object`` expose keyword-only +``trusted=False``. All public trust options use this single name and require an +actual Python ``bool``, not strings, integers or other truthy values. The example +CLIs accept ``--trusted=True`` as boolean consent. Unrestricted artifact loads +emit an unsafe-loading warning and may execute code with the loading process's +permissions. The flag does not validate, sanitize or authenticate the contents. + +``MLflowRecorder.load_object(name, unpickler=None, *, trusted=False)`` also accepts +a custom unpickler. That is trusted code, emits an unsafe-loading warning, and is +not a sandbox or a way to make unknown artifacts safe. A custom ``unpickler`` and +``trusted=True`` are mutually exclusive and raise ``ValueError`` together; choose +one deliberate loading policy, not both. + +Verify **both source and store**: who produced the artifact, how it reached the +run, and who can replace it. Restrict write access to MLflow artifact directories, +shared filesystems and remote object stores. Creating a run yourself is not +enough if another user or job can overwrite its artifacts. Prefer dedicated, +access-controlled storage. + +There is no automatic fallback to ordinary pickle. Do not catch a restricted-load +failure and retry with ``trusted=True``. A refusal may indicate an unsupported +representation, a missing dependency or executable content; it does not establish +trust. Inspect the reported type and provenance. Do not expand the global class +allowlist simply to suppress a model-loading error. + +Workflow-level entry points +=========================== + +These public entry points use default-off ``trusted=False`` so callers need not +patch internal recorder loads: + +* ``RMDLoader``, ``DSBasedUpdater``, ``PredUpdater`` and ``LabelUpdater``: + model/dataset loads needed for updating. +* ``OnlineToolR`` and ``RollingStrategy``: executable task/model/dataset reads. + A strategy forwards its setting to the online tool it creates, then through the + updater to the loader. +* ``DelayTrainerR`` and ``DelayTrainerRM``: saved task reads when finishing delayed + training. Constructor consent reaches ``end_train`` and the ``DelayTrainerRM`` + worker. Direct callers can use ``end_task_train(..., trusted=True)`` or pass an + explicit ``trusted`` override to ``end_train``/``worker`` for that call. +* ``DDGDA``: recorder-backed meta-model/task reads and the local handler and + ``InternalData`` caches needed by that workflow, described below. +* ``MetaDatasetDS`` and ``InternalData.setup``: lower-level recorder task reads. + Their recorder consent alone does not authorize unrelated local pickle caches. + +For example, after checking this workflow's artifact sources: + +.. code-block:: python + + from qlib.model.trainer import DelayTrainerR + from qlib.workflow.online.manager import OnlineManager + from qlib.workflow.online.strategy import RollingStrategy + + strategy = RollingStrategy( + "my_strategy", + task_template=task_template, + rolling_gen=rolling_gen, + trusted=True, + ) + trainer = DelayTrainerR(trusted=True) + manager = OnlineManager(strategy, trainer=trainer) + +Ordinary ``TrainerR``/``TrainerRM`` and ``OnlineManager`` have no ``trusted`` +constructor option. Configure each strategy, including ones added later, and +configure a caller-supplied delayed trainer separately. A workflow does not +silently change that trainer's policy. + +Consent covers the necessary executable objects, not every artifact in a run. +Prediction, label and numerical-report reads in these workflows remain restricted +even when ``trusted=True``. See :ref:`online_serving` and the +`example commands `_. + +Restored managers and components +--------------------------------- + +Only restore a local serialized ``OnlineManager`` from an independently trusted +source. Its strategies, tools and delayed trainer retain their own saved settings; +previously released objects without a trust field default to ``False``. + +After reviewing each source, explicitly reconfigure or recreate every affected +strategy, its ``strategy.tool``, and any delayed trainer. Changing only +``strategy.trusted`` does not update an already-created tool. A new example +constructor or CLI flag does not overwrite a manager subsequently restored from +disk. ``add_strategy`` applies the current flag to new strategies only. There is +no manager-wide permission or revocation. + +Pre-release trial artifact compatibility +----------------------------------------- + +The earlier PR trial spelling ``trusted_artifacts`` was not a released API. New +public constructor keywords and CLI flags must use ``trusted``; there is no +public alias and ``--trusted_artifacts`` is not supported. + +A narrow compatibility path supports saved workflow objects from those trials: +boolean ``trusted_artifacts`` state migrates to ``trusted`` with a visible +``FutureWarning`` linking to this guide. Missing fields default to ``False``; +non-booleans and conflicting old/new values are rejected rather than guessed. +Saving those workflow objects again writes only ``trusted`` in their trust state. +The private DDG-DA cache-loader factory also interprets the old keyword in saved +configurations with a warning at that boundary only. It does not rewrite the +caller's plain dictionary or saved file: simply re-saving an old task dictionary +does not rename its keys. Cache-loader configurations generated or regenerated +through the workflow use ``trusted``. + +This support is for trial artifacts, not a reason to keep using the old spelling +or to trust an unknown pickle. Previously released objects without either flag +remain fail closed. + +DDG-DA caches and exported tasks +================================ + +``DDGDA(..., trusted=True)`` (CLI: ``--trusted=True``) authorizes the necessary +recorder objects and DDG-DA's local handler/``InternalData`` pickle cache reads. +Check ``working_dir``, the configuration directory used for handler caches, any +explicit ``h_path``, and the MLflow store, including all write permissions. +Restricted cache loads refuse executable handlers and ``InternalData`` objects. +Explicit consent uses ordinary pickle with a warning; it neither authenticates +files nor relaxes the global restricted loader. + +Generated tasks keep a lightweight handler-cache **configuration reference**, +including its path and selected ``trusted`` setting, instead of embedding all +market data. Code consuming ``task["dataset"]["kwargs"]["handler"]`` must not +assume it is a ``file://`` string. Treat exported tasks as executable +configurations: their selected cache consent persists when saved and reused, +independently of a newly created workflow's default setting. + +An old exported task may need regeneration using its matching meta-model and +workflow configuration to obtain the current cache-loader reference and policy. +Reloading a recorder task containing a reweighter still requires recorder consent; +that flag alone does not globally permit local caches referenced by the task. +Do not delete experiments or retrain everything just to migrate normal trusted +artifacts. See the +`DDG-DA example `_ +for workflow commands and existing full-flow regression coverage. + +HIST stock-index mapping +======================== + +The bundled mapping is now +``examples/benchmarks/HIST/qlib_csi300_stock_index.json``, preserving all **735 +entries** and their concept-matrix row assignments. Update +``task.model.kwargs.stock_index`` in custom YAML from the old object ``.npy`` path +to this JSON file. The bundled workflow already uses JSON. + +An old saved HIST model also retains its own ``stock_index`` path. After +independently trusting and restoring that model, update ``model.stock_index`` to +the corresponding JSON path before prediction or further fitting; changing YAML +alone does not update a restored instance. Preserve the matching ``stock2concept`` +matrix. It remains a numeric, two-dimensional ``.npy`` file loaded without pickle, +not JSON, and must contain the unknown-stock row **733** (at least **734 rows**). +Every mapped index must also be within the matrix's row bounds. + +For a known-trusted custom mapping, re-export from the original trusted metadata +or producer into a JSON object with instrument strings as keys and non-negative +integer row indices as values (not booleans, floats or strings). Preserve each +instrument's row assignment. Merely renaming a file does not convert it. +Object-pickled ``.npy`` mappings remain refused even with recorder/workflow +``trusted=True``. Do not load an unknown object file to convert it; recover or +regenerate trusted source metadata instead. See the +`HIST example `_. + +High-frequency provider artifact paths +====================================== + +``HighFreqProvider`` confines artifact paths to ``artifact_root``, which defaults +to the current working directory at construction. Choose a dedicated, +access-controlled root and update feature, label and backtest configuration paths +accordingly. Relative paths resolve against this root, not an arbitrary later +working directory. + +All configured and derived paths, including split, per-day and per-stock files, +must remain inside the root after canonical resolution (including symlinks and +``..``). Returned artifact paths are canonical absolute paths; callers should use +them rather than assuming the original relative spelling is preserved. A trust +flag does not bypass path containment. Do not use ``artifact_root="/"`` as a +workaround; move/reconfigure artifacts within the intended dedicated root. + +Containment does not make cache contents safe: these dataset caches still contain +Python pickles and must be independently trusted. Re-create an old serialized +provider that lacks ``artifact_root`` using reviewed configuration and an explicit +root rather than relying on a missing-field fallback. + +Supported data and version compatibility +======================================== + +The restricted loader supports common built-in containers, NumPy arrays/scalars +and pandas ``Series``/``DataFrame`` objects, including typical prediction/label +``MultiIndex`` layouts. Supported reconstruction cases include pickle protocols +4 and 5, NumPy masked arrays, pandas nullable integer/float/boolean and +Python-backed string arrays, categorical data, datetime/timedelta data, supported +timezone metadata (such as UTC and ``pytz``), period/interval data and sparse arrays. + +Not every dtype or object is supported. Object-dtype cells, custom subclasses, +extension arrays and metadata can introduce executable classes. Arrow-backed +pandas data and ``zoneinfo.ZoneInfo``-backed timezones are not supported by default. +The representation depends on Python, NumPy and pandas versions and dtype +settings. Regenerate supported data in a trusted producer environment rather than +enabling unrestricted loading simply to read predictions or numerical reports. + +Pickle's cross-version limitations still apply. Protocol support does not +guarantee compatibility across Python, NumPy, pandas or model-library versions, +and ``trusted=True`` does not fix missing or renamed classes. Preserve the +producing environment for legacy executable artifacts and test representative +loads before upgrading. + +Custom recorders, loaders and completion callbacks +================================================== + +Custom recorders should implement ``load_object(self, name, *, trusted=False)``, +validate actual boolean consent and enforce restricted loading by default. +Unrestricted loading requires explicit ``trusted=True``. Never ignore the flag or +add an unsafe retry. + +For compatibility, ``R.load_object(name)`` and ``R.load_object(name, trusted=False)`` +call a legacy recorder's ``load_object(name)`` without a new keyword; explicit +``trusted=True`` is forwarded. This preserves default call signatures, **not a +custom backend's security**. A legacy backend using ordinary pickle must implement +the restricted default itself. Adapt its signature before using explicit consent +through ``R``; do not rely on this facade accommodation for direct backend calls. + +An updater's default construction of a custom ``loader_cls`` likewise omits the +new keyword when consent is ``False``. Opted-in construction forwards +``trusted=True``; adapt the loader's constructor, for example +``__init__(self, rec, *, trusted=False)``, and enforce its policy on executable +artifact loads. Data-only reads must remain restricted. + +Custom delayed-training completion callbacks should accept +``end_train_func(rec, experiment_name, *, trusted=False)`` (plus any existing +workflow arguments), validate the boolean, and pass consent only to necessary +executable task reads. Default delayed completion preserves legacy callback calls +without adding the keyword when no consent/override is requested. Opted-in trainers +and explicit per-call overrides forward ``trusted`` to the callback, including in +``DelayTrainerRM`` workers; accepting it without enforcing the policy is not enough. + +Other executable inputs are independent +======================================= + +.. warning:: + + This is a scoped artifact policy, not an all-Qlib sandbox or global + authorization. Apart from DDG-DA's explicitly covered caches, existing local + pickle/model loaders, serialized manager files, handler caches and MongoDB + task stores retain their own trust requirements.

Mon, 21 Sep 2026 15:30:11 +0000 Subject: [PATCH 25/26] ci: avoid failed dataset probes and space download retries Download the same existing v2 archives used by successful jobs without probing nonexistent package-version assets. Allow five download attempts 60 seconds apart; preserve the full matrix, datasets, noninteractive setup and failure propagation. Cover the exact archives and retry policy in offline CI tests.
