…API input External construction now rejects a parameter whose type includes Path unless the calling service passes the name in allowed_path_params after making the value safe. The converter service allows its upload parameters once they are stored, and the target service allows the server-set upload folder and the GitHubCopilotTarget working directory. The scorer-only check is removed, and the "Valid parameters" list leaves out path parameters callers cannot set.
The target catalog now applies the path rule to required parameters too, so a target that needs a disallowed path is left out instead of listed without the field, matching the scorer catalog. allowed_path_params is typed frozenset[str] so a bare string cannot turn the allow-list into a substring match.
The target catalog still lists a target whose required path parameter is its server-set upload folder when the server has one, and leaves it out otherwise.

FileDocumentStorage now raises DocumentStorageUnavailableError when the folder or container can't be used, and DocumentUnreadableError when one document exists but can't be read. The message names the location, with any SAS token hidden, and a short reason. One backend handler maps both to 503 and logs the location and reason, with the traceback at debug level, so the per-route storage helpers are gone. A single read, a conditional save and a delete now follow the listing's rules: a folder, pipe or broken link named like a document is unreadable rather than missing, and on Blob only a deleted blob counts as missing. Blob sign-in, permission, network and missing-container errors stop the listing instead of marking every file unreadable. Each unreadable report keeps the real file name and the original error, and the listing's documents are read-only. Initializer delete removes a script that can't be read or decoded, and registering one no longer turns a storage write failure into a 400. Tests patch module-level aliases instead of os.
List recipes escapes the OS text it reports, such as a file name that isn't UTF-8, and a recipe whose JSON holds an unpaired surrogate escape is reported as invalid, so the models no longer need a JSON-only serializer. Recipes may start with a byte-order mark. A document without schema_version reads as version 1, and each file is checked against the format version of the model that reads it. Validation summaries shorten each location part and the whole message, since a location can repeat a stored key. Recipes and StoredRecipe are no longer frozen, since their params and tags never were, and StoredRecipe checks that its recipe type matches its registry. The listing's recipes are read-only, and it keeps the error behind each recipe that couldn't be read, for the log.
Listing catches only storage errors, so a bug is raised instead of being reported as unreadable storage, and a bug while planning is a build error rather than an invalid recipe. Each failure is logged once, with the error behind it and URL credentials removed. The report shows the error's text with each URL's user name, query and fragment removed, any SAS signature hidden, and the length capped. A class that moved within PyRIT is restored; one now registered from outside PyRIT still fails. A technique whose name or tag clashes is a name clash, and anything else registration refuses is an invalid recipe. A recipe that sets a server file or folder is refused before it is built. Class metadata comes from the registry's cache. The class docstring lists the steps the API's create runs that restore skips.
The runtime becomes ready even when some saved entries fail; the failures stay in the runtime status. Each failed entry keeps its name in its registry: looking it up, or taking the name, raises SavedEntryUnavailableError, which the backend answers with 409, so nothing else stands in for it. Administrators see the full message and everyone else a fixed explanation of the reason. A folder that can't be listed holds every unregistered name of its kind, and each entry it left unbuilt is reported. While a saved technique is held, a launch or estimate that picks techniques by all, default or a tag is refused with 409 for scenarios whose techniques come from the registry, since the broken technique's tags may be unknown. Naming techniques still works; naming the held one fails with its reason. Route catch-alls let the error through instead of turning it into a 500.
A launch script that registers a name held for a saved entry that couldn't be restored is refused, and the refusal is recorded even when the script catches it, so the launch stops instead of running with the script's entry in the saved one's place. A suite entry that fails on a held entry, or on a broad technique selection, shows the reason without the error's details.
The OpenAI SDK adds that variable's headers to every request, so a saved OpenAI target would send whatever the server puts there, which can be a credential. While it's set, saving an OpenAI target is refused and a saved one isn't restored; the message names the variable, never its value. Targets declare such variables in server_header_variables.

Description
This is one of the changes for saving Registry entries across restarts. It builds on #4028. Until the earlier PRs merge, the diff here also shows their changes.
A saved converter or scorer is rebuilt at every start and shared by everyone using the app, so restore should refuse one that would sign in with this server's own credentials, as it already does for targets (#4025).
AzureContentFilterScorerread this server's key when theirs is empty, or else sign in with its Azure identity, and no value turns that off. They now list that key inserver_fallback_parameters(azure_speech_key,api_key), so the shared saved-entry check refuses them, as it does for targets.AudioTrueFalseScorerandAudioFloatScaleScorertranscribe with this server's Speech settings.LocalRefusalClassifierScorerloads its model from a folder on this server, or downloads it with this server's Hugging Face sign-in. These get anot_saveable_reason, likeWebSocketCopilotTargetandHuggingFaceChatTargetin FIX: Refuse saved targets that would authenticate with a key (part 7) #4025.server_fallback_parametersis now on theConverterandScorerbases, andnot_saveable_reasononScorer, as onPromptTarget.api_keyin the saved-entry check, ascheck_saveable_classalready assumed. A recipe can no longer pass by naming an auth mode its class doesn't take.pyrit_conf.mdlists the converters and scorers that can't be saved yet.Converters and scorers made without saving, and the ones the startup scripts register, aren't checked.
RobloxPiiScorerandLocalViolenceClassifierScorercan still be saved: their models are fixed public ones and nothing a caller sets.Not covered: saving converters and scorers through the API, which is #4051 (part 12). Picking a server credential, or keeping typed keys in a key vault, would let the Speech converters and the Content Safety and audio scorers be saved later.
