fix(ag-grid-table): reject null/empty IN_RANGE bounds and tighten tests

Number(null) and Number('') both coerce to 0, so a null/empty filterTo
would silently produce "BETWEEN x AND 0" instead of dropping the clause.
Explicitly reject non-coercible (null/empty) bounds before coercion.

Also strengthen the converter tests to assert the surviving sibling
condition and the full compound WHERE clause, so they fail if filter
composition or the upper bound regresses.

+# Security Policy
+
+This is a project of the [Apache Software Foundation](https://apache.org) and follows the
+ASF [vulnerability handling process](https://apache.org/security/#vulnerability-handling).
+
+## Reporting Vulnerabilities
+
+**⚠️ Please do not file GitHub issues for security vulnerabilities as they are public! ⚠️**
+
+
+Apache Software Foundation takes a rigorous standpoint in annihilating the security issues
+in its software projects. Apache Superset is highly sensitive and forthcoming to issues
+pertaining to its features and functionality.
+If you have any concern or believe you have found a vulnerability in Apache Superset,
+please get in touch with the Apache Superset Security Team privately at
+e-mail address [security@superset.apache.org](mailto:security@superset.apache.org).
+
+More details can be found on the ASF website at
+[ASF vulnerability reporting process](https://apache.org/security/#reporting-a-vulnerability)
+
+**Submission Standards & AI Policy**
+
+To ensure engineering focus remains on verified risks and to manage high reporting volumes, all reports must meet the following criteria:
+- Plain Text Format: In accordance with Apache guidelines, please provide all details in plain text within the email body. Avoid sending PDFs, Word documents, or password-protected archives.
+- Mandatory AI Disclosure: If you utilized Large Language Models (LLMs) or AI tools to identify a flaw or assist in writing a report, you must disclose this in your submission so our triage team can contextualize the findings.
+- Human-Verified PoC: All submissions must include a manual, step-by-step Proof of Concept (PoC) performed on a supported release. Raw AI outputs, hypothetical chat transcripts, or unverified scanner logs will be closed as Invalid.
+
+We kindly ask you to include the following information in your report to assist our developers in triaging and remediating issues efficiently:
+- Version/Commit: The specific version of Apache Superset or the Git commit hash you are using.
+- Configuration: A sanitized copy of your `superset_config.py` file or any config overrides.
+- Environment: Your deployment method (e.g., Docker Compose, Helm, or source) and relevant OS/Browser details.
+- Impacted Component: Identification of the affected area (e.g., Python backend, React frontend, or a specific database connector).
+- Expected vs. Actual Behavior: A clear description of the intended system behavior versus the observed vulnerability.
+- Detailed Reproduction Steps: Clear, manual steps to reproduce the vulnerability.
+
+**Out of Scope Vulnerabilities**
+
+To prioritize engineering efforts on genuine architectural risks, the following scenarios are explicitly out of scope and will not be issued a CVE:
+- Attacks requiring Admin privileges: (e.g., CSS injection, template manipulation, dashboard ownership overrides, or modifying global system settings). Per the CVE vulnerability definition in CNA Operational Rules 4.1, a qualifying vulnerability must allow violation of a security policy. The Admin role is a fully trusted operational boundary defined by Apache Superset's security policy; actions within this boundary do not violate that policy and are therefore considered intended capabilities 'by design,' not vulnerabilities.
+- Brute Force and Rate Limiting: Reports targeting a lack of resource exhaustion protections, generic rate-limiting, or volumetric Denial of Service (DoS) attempts.
+- Theoretical attack vectors: Issues without a demonstrable, reproducible exploit path.
+- Non-Exploitable Findings: Missing security headers, generic banner disclosures, or descriptive error messages that do not lead to a direct, documented exploit.
+
+**Outcome of Reports**
+
+Reports that are deemed out-of-scope for a CVE but represent valid security best practices or hardening opportunities may be converted into public GitHub issues. This allows the community to contribute to the general hardening of the platform even when a specific vulnerability threshold is not met.
+
+Note that Apache Superset is not responsible for any third-party dependencies that may
+have security issues. Any vulnerabilities found in third-party dependencies should be
+reported to the maintainers of those projects. Results from security scans of Apache
+Superset dependencies found on its official Docker image can be remediated at release time
+by extending the image itself.
+
+**Vulnerability Aggregation & CVE Attribution**
+
+In accordance with MITRE CNA Operational Rules (4.1.10, 4.1.11, and 4.2.13), Apache Superset issues CVEs based on the underlying architectural root cause rather than the number of affected endpoints or exploit payloads.
+- Aggregation: If multiple exploit vectors stem from the same programmatic failure or shared vulnerable code, they must be aggregated into a single, comprehensive report.
+- Independent Fixes: Separate CVEs will only be assigned if the vulnerabilities reside in decoupled architectural modules and can be fixed independently of one another.
+Reports that fail to aggregate related findings will be merged during triage to ensure an accurate and defensible CVE record.
+
+**Your responsible disclosure and collaboration are invaluable.**

-## Security and Threat Model
-
-Before evaluating any code path for security issues, read [`SECURITY.md`](SECURITY.md). It is the canonical, authoritative source for Apache Superset's security model and is referenced by both human reporters and automated scanners.
-
-In short, the test for whether a finding is in scope is one question:
-
-> *Does it let a principal perform an action the role and capability matrix in `SECURITY.md` does not entitle them to?*
-
-If yes, it is in scope. If no, it is not.
-
-The three trust boundaries are:
-
-1. **The Admin role** is a fully trusted operational principal. Anything an Admin can do through documented configuration, API, or UI is an intended capability, not a vulnerability.
-2. **The operator** owns deployment-time decisions (secrets, network exposure, feature-flag selection, connector and codec choices, notification destinations, third-party plugins). Misconfiguration at this layer is a deployment defect, not a Superset vulnerability.
-3. **The codebase** is responsible for enforcing the role and capability matrix wherever it exposes functionality to a principal: API routes, command and DAO layers, UI handlers, background jobs, and any other entry point. A missing or incorrect enforcement check is in scope no matter where it lives.
-
-The security model assumes that operator-controlled infrastructure, including the metadata database, cache backends, message brokers, secret stores, and deployment environment, remains within the operator's trust boundary. Vulnerabilities must demonstrate a security boundary violation by an attacker who does not already control those systems.
-
-Route-level authorization in this codebase uses one of three Flask-AppBuilder decorators depending on the route type:
-
-- `@protect()` for REST API routes (`ModelRestApi` / `BaseApi`)
-- `@has_access_api` for legacy view routes
-- `@has_access` for legacy HTML view routes
-
-Object-level authorization via `security_manager.raise_for_access(...)` applies to data-bearing resources: dashboards, charts, datasets and datasources, queries, database and table access, and query contexts. Other resources (annotations, tags, CSS templates, reports, RLS rules, and similar) rely on the route-level decorator plus DAO `base_filters` for ownership scoping; the absence of `raise_for_access` on these resources is by design, not a finding. Code that omits the per-object gate on a route that returns or mutates a specific data-bearing object is in scope; code that follows the correct pattern for its resource class can still contain injection, SSRF, XSS, or other classes of finding unrelated to authorization, which are evaluated separately.
-
-The full role and capability matrix, in-scope and out-of-scope class lists, and CVE aggregation rules are in [`SECURITY.md`](SECURITY.md). Defer to that document for any specifics.
-
-**Requirements for findings filed by automated tooling**
-
-Automated scanners (LLM-based code scanners, static analyzers, dependency tools) that file findings against this codebase must, in each finding, name:
-
-1. The specific role and capability matrix row in [`SECURITY.md`](SECURITY.md) the finding believes is violated.
-2. The principal the finding assumes the attacker holds (Public, Gamma, sql_lab, Alpha, Admin, Embedded guest token, or a custom role with explicit capability grants).
-
-Findings that cannot identify both should be filed as questions, not vulnerabilities. This requirement exists to ensure every reported issue is testable against the published security model and to keep speculative or pattern-match-only reports out of the triage queue.

-Chatbot extensions
-Author: Enzo Martellucci
-Team: Preset
-Status: Draft | Under Review | Completed
-Day: May, 2026
-
-1. Introduction
-   This SIP proposes a new extension point that enables third-party chatbot integrations to be embedded directly into the Superset user interface through the existing extension framework.
-   The goal is to provide a stable, supported mechanism for chatbot providers to integrate with Superset without requiring direct access to internal application state, Redux stores, or implementation-specific frontend modules. Chatbot extensions should interact with Superset through the same extension-oriented principles already established for other extension surfaces, such as SQL Lab.
-   The proposal focuses on three core concerns:
-   • Defining how chatbot extensions are registered and rendered.
-   • Defining how chatbot extensions receive contextual information about the currently active application surface.
-   • Defining how administrators manage chatbot availability and select the active chatbot when multiple chatbot extensions are installed.
-   This SIP intentionally does not prescribe any specific chatbot implementation, user experience, LLM provider, or backend architecture.
-   1.1 Motivation
-   AI-powered assistants are becoming a common way for users to interact with analytical applications. Superset should provide a standardized extension mechanism that allows community-built chatbot integrations to participate in the platform without depending on internal frontend implementation details.
-   Today, chatbot integrations must either be embedded through custom application modifications or rely on unsupported access to internal application state. Both approaches create maintenance challenges and make integrations fragile when frontend architecture evolves.
-
-This SIP introduces a stable extension contract that:
-• Enables chatbot integrations to be distributed as standard Superset extensions.
-• Preserves separation between host and extension responsibilities.
-• Allows chatbot implementations to access contextual information about the current page and entity being viewed.
-• Keeps authorization and permission enforcement aligned with existing Superset APIs.
-• Remains compatible with future frontend architecture changes.
-1.2 Goals
-The goals of this SIP are:
-Introduce a dedicated chatbot extension point within the Superset application shell.
-Provide chatbot extensions with host-managed, permission-aligned page context.
-Establish stable extension-facing APIs for dashboard, explore, dataset, and navigation context.
-Support deployment-wide administration of chatbot availability and selection.
-Maintain isolation between chatbot implementations and Superset internals.
-Preserve compatibility with future extension capabilities and AI-related initiatives.
-1.3 Out of Scope
-The following capabilities are explicitly out of scope for this SIP.
-Client Actions and Agentic UI Manipulation
-This SIP defines how chatbot extensions are mounted and how they receive context from the host application.
-It does not define how a chatbot performs actions within the user interface, such as:
-• Modifying chart configuration.
-• Updating dashboard layouts.
-• Editing SQL queries.
-• Triggering frontend workflows.
-These capabilities are deferred to the proposed Client Actions SIP.
-Chatbot User Experience
-The chatbot user interface remains entirely owned by the extension.
-This SIP does not prescribe:
-• Visual design.
-• Conversation experience.
-• Streaming behavior.
-• Message persistence.
-• Prompting strategy.
-• Accessibility implementation details.
-• Branding or styling.
-LLM and Backend Infrastructure
-The following concerns remain extension-specific:
-• Model providers.
-• MCP implementations.
-• Agent frameworks.
-• Tool execution systems.
-• Prompt orchestration.
-• Backend services.
-Superset acts only as the host application and context provider.
-
-2. Requirements
-
-  2.1 Functional Requirements
-  Registration and Rendering
-  The platform must allow extensions to register chatbot providers through the standard extension system.
-  The host must:
-    • Support registration of chatbot extensions.
-    • Render a chatbot UI contributed by an extension.
-    • Maintain a single active chatbot instance at any given time.
-    • Make the chatbot available across supported application surfaces.
-    • Support fully custom chatbot user interfaces.
-
-Context Sharing
-The platform must provide chatbot extensions with contextual information about the user's current application state.
-At minimum, the host must expose:
-• Current page type (`home`, `dashboard`, `explore`, `sqllab`, `dataset`, `other`).
-• Dashboard context.
-• Explore/chart context.
-• Dataset identity context.
-• SQL Lab context.
-• Navigation events.
-The chatbot must be notified of relevant context changes without polling.
-Examples include:
-• Route changes.
-• Dashboard changes.
-• Chart changes.
-• Dataset changes.
-• Title changes.
-• Filter changes.
-Host-Owned Context
-Context exposed to extensions must be computed by the host application.
-Extensions must not be required to:
-• Read Redux state.
-• Access internal application modules.
-• Depend on component-level implementation details.
-• Reconstruct semantic context from frontend internals.
-Instead, extensions consume stable namespace APIs provided by the host.
-Conversation State
-The conversation state remains entirely owned by the chatbot extension.
-This includes:
-• Message history.
-• Tool execution state.
-• Streaming buffers.
-• Conversation persistence.
-• Session management.
-The host is responsible only for exposing contextual information.
-2.2 Non-Functional Requirements
-Security and Authorization
-Context shared with chatbot extensions must remain aligned with Superset's existing authorization model.
-The host must not expose:
-• Entities the current user cannot access.
-• Metadata outside the user's permission scope.
-• Datasource-derived information unavailable through existing APIs.
-Authorization remains enforced by backend APIs. The extension-facing APIs defined by this SIP operate on data that has already been scoped to the current user.
-Stable Extension Contracts
-Extension-facing APIs must remain independent of frontend implementation details.
-Extensions should rely on documented namespace contracts rather than:
-• Redux slices.
-• Internal selectors.
-• Component state.
-• Routing implementation details.
-This allows frontend architecture to evolve without breaking extensions.
-Performance
-The architecture must minimize impact on existing application performance.
-In particular:
-• Context APIs must avoid unnecessary application re-renders.
-• Context change notifications must not rely on polling.
-• Chatbot integrations should not introduce additional work for unrelated surfaces.
-Fault Isolation
-Failures within chatbot extensions must not affect the stability of the host application.
-Errors originating from third-party chatbot implementations should be isolated to the chatbot mount boundary.
-Extensibility
-The architecture should support future:
-• Application surfaces.
-• AI-related capabilities.
-• Extension APIs.
-• Context providers.
-without requiring redesign of the chatbot extension model.
-Vendor Neutrality
-The architecture must remain independent of any specific:
-• LLM provider.
-• AI platform.
-• Agent framework.
-• Backend implementation.
-
-3. Administration
-   3.1 Overview
-   Administrators can manage chatbot availability and select the active chatbot when multiple chatbot extensions are installed.
-   Administration is exposed through the existing Extensions management interface.
-   For chatbot extensions, administrators can:
-   • Enable or disable individual chatbot extensions.
-   • Select the default chatbot when multiple chatbot providers are available.
-   Only one chatbot may be active at a time.
-   3.2 Default Chatbot Selection
-   Extensions that contribute a chatbot view participate in a deployment-wide chatbot selection process.
-   The host discovers available chatbot candidates from the chatbot contribution location and allows administrators to designate a single active chatbot.
-
-When multiple chatbot extensions are installed:
-Administrators select the preferred chatbot.
-The host resolves the active chatbot using the configured selection.
-Only the selected chatbot is rendered.
-Changes are applied dynamically without requiring a page reload.
-3.3 Scope of Administration
-The administration model introduced by this SIP is deployment-wide.
-Administrative settings answer the question:
-"Which chatbot integrations are available within this Superset deployment?"
-They do not answer:
-"Which chatbot integrations does a specific user prefer to use?"
-This distinction is intentional.
-Deployment administrators determine which integrations are available across the environment, while user-specific preferences remain a separate concern.
-3.4 Future User Preferences
-Per-user chatbot preferences are considered an important future capability but are intentionally out of scope for this SIP.
-This proposal does not introduce user-scoped extension availability.
-Instead, future user preferences should be layered on top of deployment availability using the following model:
-Effective Availability = Deployment Availability AND User Preference
-The recommended persistence layer for future user preferences is the Extension Storage API, which provides user-scoped extension storage and aligns with the architecture established by SIP-127 (User Preferences).
-This separation preserves a clear distinction between:
-• Deployment configuration.
-• User customization.
-and avoids introducing multiple ownership models for extension availability.
-Consequently, this SIP focuses exclusively on deployment-wide administration and active chatbot selection. 4. Proposed Extension Point
-4.1 Overview
-This SIP introduces a single extension point that allows chatbot providers to integrate directly into the Superset application shell.
-Extension Point
-Contribution Location
-Registration API
-Cardinality
-Chatbot Bubble
-superset.chatbot
-views.registerView()
-Singleton
-
-The chatbot contribution point is application-wide and persists across supported Superset surfaces, including dashboards, Explore, SQL Lab, and dataset-related pages.
-Unlike most contribution locations, which allow multiple contributions to be rendered simultaneously, the chatbot location is intentionally exclusive and renders a single active provider.
-
-4.2 Chatbot Contribution Location
-Contribution Area
-The contribution location introduced by this SIP is:
-superset.chatbot
-The host provides a fixed mount point within the application shell and renders the active chatbot provider at that location.
-The mount point persists across route changes, allowing chatbot conversations and UI state to remain available while users navigate between application surfaces.
-The chatbot extension contributes a single React component representing the entire chatbot experience.
-Manifest Support
-The current contribution manifest schema is focused on SQL Lab contribution locations and does not provide an application-shell-level contribution scope.
-To support chatbot integrations, the manifest schema must be extended with an application-level contribution scope capable of declaring:
-{
-"views": {
-"app": [
-{
-"location": "superset.chatbot"
-}
-]
-}
-}
-This is a schema-level change and requires updates to both:
-• Manifest validation.
-• Runtime registration infrastructure.
-The runtime registration API alone is not sufficient because chatbot contributions must also be discoverable through extension manifests.
-4.3 Singleton Rendering Model
-The chatbot location is intentionally exclusive.
-Only one chatbot may be active at a time.
-This differs from other contribution locations that allow multiple views to be rendered simultaneously.
-Motivation
-Chatbot interactions are inherently conversational and user-focused.
-Rendering multiple chatbot providers simultaneously would:
-• Create competing user experiences.
-• Introduce ambiguity regarding which chatbot should respond.
-• Increase UI complexity.
-• Reduce discoverability.
-For these reasons, chatbot rendering is treated as a deployment-level selection rather than a multi-provider composition model.
-Resolution Rules
-The host applies the following behavior:
-Installed Chatbots
-Behavior
-None
-No chatbot is rendered
-One
-The chatbot is rendered automatically
-Multiple
-The administrator-selected chatbot is rendered
-
-The singleton policy is implemented entirely by the host.
-Extensions continue to register normally through the existing view registry.
-4.4 Provider Isolation
-A key architectural principle of this SIP is that extensions may discover registrations but may not invoke another extension's rendering logic.
-Public View Discovery
-The existing registry exposes:
-getViews(location);
-This API returns metadata describing registered views:
-interface View {
-id: string;
-name: string;
-description?: string;
-icon?: string;
-}
-The returned descriptors are intentionally passive metadata.
-They allow extensions and host components to:
-• Discover available contributions.
-• Display contribution information.
-• Populate administration interfaces.
-They do not allow rendering.
-Why Providers Are Not Exposed
-The view provider is executable rendering logic.
-If providers were exposed through the public registry:
-• Extensions could render another extension's UI.
-• Extensions could bypass host lifecycle management.
-• Extensions could circumvent fault-isolation boundaries.
-• Rendering ownership would become ambiguous.
-This would violate the separation between extension discovery and extension execution.
-For this reason:
-"Extensions may discover registered views, but only the host may render registered views."
-Host-Managed Resolution
-The host uses internal APIs to resolve the active chatbot provider.
-These APIs are not exposed through the public extension surface.
-Conceptually:
-const provider = getViewProvider("superset.chatbot", selectedId);
-The active chatbot is determined through a host-managed resolution policy:
-const chatbot = getActiveChatbot(adminSelectedId, enabledMap);
-This policy considers:
-• Enabled state.
-• Administrative selection.
-• Runtime settings.
-• Registration state.
-
-before rendering any provider.
-As a result, chatbot selection is implemented as a host-side rendering policy rather than a new registration primitive.
-4.5 Chatbot Lifecycle
-Host Responsibilities
-The host is responsible for:
-• Providing the chatbot mount point.
-• Resolving the active chatbot provider.
-• Loading chatbot extensions.
-• Managing chatbot lifecycle integration.
-• Handling activation and deactivation.
-• Maintaining fault isolation boundaries.
-• Preserving chatbot availability across route changes.
-• Providing context APIs defined by this SIP.
-The host also provides fixed positioning and layering behavior to ensure chatbot visibility remains consistent throughout the application.
-Fault Isolation
-Chatbot providers execute within a host-managed boundary.
-Failures originating from a chatbot extension must not affect the rest of the application.
-Examples include:
-• Module Federation loading failures.
-• Runtime exceptions.
-• Provider initialization errors.
-If a chatbot fails to load, the host logs the failure, surfaces an appropriate notification, and continues operating normally.
-The application shell remains functional even when the chatbot provider is unavailable.
-
-4.6 Extension Responsibilities
-The registered chatbot component owns the complete chatbot experience.
-The extension is responsible for:
-User Interface
-• Collapsed bubble UI.
-• Expanded panel UI.
-• Branding.
-• Icons and badges.
-• Layout.
-• Responsiveness.
-Interaction Model
-• Open and close behavior.
-• Keyboard shortcuts.
-• Focus management.
-• Accessibility behavior.
-• Conversation navigation.
-Conversation Runtime
-• Message history.
-• Streaming state.
-• Tool execution.
-• Persistence.
-• Session management.
-Backend Integration
-• LLM communication.
-• MCP integration.
-• Agent orchestration.
-• Tool invocation.
-The host does not manage any chatbot-specific runtime state.
-
-4.7 Registration Example
-Chatbot extensions register a single provider through the existing view registration API.
-import { views, type ExtensionContext } from '@apache-superset/core';
-import { ChatbotApp } from './ChatbotApp';
-
-export function activate(context: ExtensionContext) {
-const disposable = views.registerView(
-{
-id: 'acme.chatbot',
-name: 'Acme Chatbot',
-icon: 'Bubble',
-},
-'superset.chatbot',
-() => <ChatbotApp />,
-);
-context.subscriptions.push(disposable);
-}
-The registration process remains consistent with existing extension contribution patterns.
-The only difference is that the host applies singleton resolution before selecting the provider to render.
-
-4.8 Chatbot Descriptor Metadata
-Chatbot registrations may include an optional icon descriptor.
-{
-id: 'acme.chatbot',
-name: 'Acme Chatbot',
-icon: 'Bubble',
-}
-This metadata is used by:
-• Extension administration interfaces.
-• Chatbot selection interfaces.
-• Extension discovery surfaces.
-Design Decision
-The icon descriptor is treated as static registration metadata.
-Runtime UI state such as:
-• Notification indicators.
-• Unread counts.
-• Loading states.
-• Thinking indicators.
-belongs to the chatbot component itself rather than the registration descriptor.
-This keeps the registry simple while allowing chatbot implementations complete control over their user experience.
-If future requirements emerge for host-visible dynamic icon updates, that capability can be introduced independently without expanding the registration model defined by this SIP. 5. Context and Namespace Model
-5.1 Overview
-Chatbot extensions require access to contextual information about the user's current activity within Superset. This SIP introduces a namespace-based context model that allows extensions to consume stable, host-managed APIs rather than depending on internal frontend implementation details.
-The host exposes context through a set of surface-specific namespaces. Each namespace owns the context for a particular application surface and provides:
-• Synchronous state getters.
-• Event-based change notifications.
-• Stable extension-facing contracts.
-• Context aligned with the current user's authorized application view.
-Extensions consume these namespaces and compose them into higher-level context models tailored to their own use cases.
-5.2 Design Principles
-The namespace model is guided by the following principles.
-Stable Extension Contracts
-Extensions must depend on documented APIs rather than frontend implementation details.
-In particular, extensions must not depend on:
-• Redux slices.
-• Store shape.
-• Selectors.
-• Component-local state.
-• Routing implementation details.
-This allows Superset to evolve its frontend architecture without breaking extension integrations.
-Host-Owned Context Normalization
-The host is responsible for transforming application state into semantic extension-facing contracts.
-Extensions consume normalized context rather than deriving it from raw frontend state.
-Backend-Authorized Context
-Authorization remains a backend responsibility.
-Namespaces expose context that has already been scoped by backend APIs according to the current user's permissions.
-Namespaces do not implement authorization logic themselves and should not be considered security boundaries.
-Event-Driven Updates
-Context changes are propagated through events rather than polling.
-Extensions can subscribe to context updates and react immediately when relevant application state changes.
-5.3 Available Namespaces
-The following namespaces are available to chatbot extensions.
-Namespace
-Status
-Purpose
-sqlLab
-Existing
-SQL Lab context and events
-authentication
-Existing
-Current user and session context
-commands
-Existing
-Host actions and commands
-dashboard
-New
-Dashboard context
-explore
-New
-Explore/chart context
-dataset
-New
-Dataset identity context
-navigation
-New
-Routing and page context
-
-The new namespaces introduced by this SIP follow the same high-level contract pattern established by the existing sqlLab namespace.
-5.4 Namespace API Shape
-Each namespace follows a common structure:
-const current = namespace.getCurrent();
-const disposable = namespace.onDidChange((next) => {
-// react to updates
-});
-The exact contracts differ by surface, but every namespace provides:
-• One or more synchronous getters.
-• Event-based change notifications.
-• Stable semantic contracts.
-This pattern allows extensions to remain synchronized with application state without polling.
-
-5.5 Dashboard Namespace
-The dashboard namespace provides contextual information about the currently active dashboard.
-API
-dashboard.getCurrentDashboard();
-Contract
-interface DashboardContext {
-dashboardId: number;
-title: string;
-filters: FilterValue[];
-charts: ChartSummary[];
-}
-
-interface ChartSummary {
-chartId: number;
-chartName: string;
-vizType: string;
-datasourceId: number | null;
-datasourceName: string | null;
-isVisible: boolean;}
-The context includes:
-• Dashboard identity.
-• Active filter state.
-• Dashboard charts.
-• Per-chart visibility information.
-Returning all charts while exposing visibility allows chatbot implementations to answer both:
-• "Which charts are currently visible?"
-• "Find the chart named Revenue by Region."
-without requiring additional lookups.
-Normalization Requirements
-The namespace must expose semantic dashboard context rather than raw application state.
-For example:
-dashboard.getCurrentDashboard();
-returns a normalized contract rather than Redux slices or internal entities.
-This abstraction layer preserves compatibility as frontend implementation details evolve.
-Page-Type Guarding
-The getter returns undefined when the current page is not a dashboard.
-Conceptually:
-if (navigation.getPageType() !== "dashboard") {
-return undefined;
-}
-This prevents stale dashboard state from leaking across application surfaces.
-5.6 Explore Namespace
-The explore namespace provides context for the currently active Explore session.
-API
-explore.getCurrentChart();
-Contract
-interface ChartContext {
-chartId: number | null;
-chartName: string | null;
-datasourceId: number | null;
-datasourceName: string | null;
-vizType: string;
-}
-
-The namespace exposes:
-• Chart identity. `chartId` and `chartName` are null for a new, unsaved chart that has not yet been persisted.
-• Saved chart metadata (name, datasource, viz type)
-• Current Explore context: `vizType` reflects the type currently selected in the editor, so the value tracks the live session rather than only the last saved state.
-The contract is intentionally focused on chart-specific information relevant to chatbot integrations.
-Reflecting the live editing session — rather than reconstructing chart state from
-the route alone — is the primary reason this SIP exposes frontend context
-directly (see §6.2, Option C).
-
-Page-Type Guarding
-The getter returns undefined when the current page is not an Explore surface.
-Conceptually:
-if (navigation.getPageType() !== "explore") {
-return undefined;
-}
-This ensures the namespace reflects only active Explore context.
-5.7 Dataset Namespace
-The dataset namespace exposes the dataset currently being viewed or edited.
-API
-dataset.getCurrentDataset();
-Contract
-interface DatasetContext {
-datasetId: number;
-datasetName: string;
-schema: string | null;
-catalog: string | null;
-databaseName: string | null;
-isVirtual: boolean;}
-This contract is intentionally identity-focused.
-It answers:
-• Which dataset is currently in focus?
-• Is the dataset virtual or physical?
-• Which database and schema does it belong to?
-It does not expose:
-• Column definitions.
-• Lineage information.
-• Dataset dependencies.
-Those concerns are expected to be resolved by backend services using the dataset identifier.
-Producer-Backed Context
-Unlike dashboard and explore namespaces, dataset pages do not currently expose a shared source of truth suitable for namespace consumption.
-For this reason, dataset context is published by dataset pages through a host-managed producer mechanism.
-Dataset pages publish the active dataset as it loads, and:
-dataset.getCurrentDataset();
-returns the most recently published value.
-Until dataset information has been published, the getter returns:
-undefined;
-This design keeps the public contract stable without requiring the introduction of a dedicated Redux slice.
-
-Example Use Cases
-The dataset namespace enables chatbot workflows such as:
-• Explain this dataset.
-• Summarize this dataset's purpose.
-• Show lineage for this dataset.
-• Which charts depend on this dataset?
-The namespace provides the identity required to perform those lookups while avoiding duplication of backend metadata.
-5.8 Navigation Namespace
-The navigation namespace provides routing-related context.
-API
-navigation.getPageType();
-Events
-navigation.onDidChangePage(...)
-
-Contract
-type PageType =
-| "home"
-| "dashboard"
-| "explore"
-| "sqllab"
-| "dataset"
-| "other";
-The namespace answers a single question:
-"Which application surface is currently active?"
-It intentionally does not expose entity-specific information.
-Entity context remains owned by the corresponding surface namespace.
-Examples:
-dashboard.getCurrentDashboard();
-explore.getCurrentChart();
-dataset.getCurrentDataset();
-This separation preserves clear ownership boundaries and prevents duplication across namespaces.
-
-5.9 Context Composition
-This SIP intentionally does not introduce a host-owned aggregate context object.
-Instead, extensions compose the context they require from individual namespaces.
-For example:
-const pageContext = {
-pageType: navigation.getPageType(),
-dashboard: dashboard.getCurrentDashboard(),
-chart: explore.getCurrentChart(),
-dataset: dataset.getCurrentDataset(),
-sqlLab: sqlLab.getCurrentTab(),
-};
-The extension assembles a higher-level context tailored to its own requirements.
-The host remains responsible for:
-• Context ownership.
-• Context normalization.
-• Authorization alignment.
-The extension remains responsible for:
-• Context composition.
-• Prompt construction.
-• Application-specific interpretation.
-This separation avoids introducing a centralized context abstraction while allowing new surfaces to be added incrementally over time.
-
-5.10 Compatibility and Evolution
-Namespace contracts are part of the public Superset extension API surface.
-Breaking changes require standard compatibility and deprecation processes.
-Extensions should depend only on documented namespace contracts and must not rely on implementation details behind those contracts.
-As new application surfaces become extension-aware, additional namespaces may be introduced without affecting existing integrations.
-This additive model allows the extension ecosystem to evolve while preserving backward compatibility.
-

-6.2 D1 — Page Context Model
-A central design question is how chatbot extensions obtain contextual information about the currently active application surface.
-Three approaches were considered.
-Option A — Host-Owned Aggregate Context
-The host exposes a single API:
-context.getPageContext();
-which returns a fully assembled context object containing dashboard, chart, dataset, navigation, and SQL Lab information.
-Rejected Because
-• The host becomes responsible for understanding every application surface.
-• The aggregate contract grows whenever a new surface is introduced.
-• Changes in any surface can trigger unnecessary recomputation.
-• The host becomes coupled to a single canonical context model.
-• Ownership boundaries become unclear over time.
-Option B — Surface Namespaces Composed by Extensions (Selected)
-The host exposes independent namespaces:
-• dashboard
-• explore
-• dataset
-• navigation
-• sqlLab
-Extensions compose these primitives into their own application-specific context.
-Advantages
-• Clear ownership boundaries.
-• Independent evolution of namespaces.
-• Additive extensibility.
-• Reduced coupling between surfaces.
-• Extensions subscribe only to the context they require.
-Option C — Route-Only Context
-The host exposes only routing information.
-Chatbot providers independently reconstruct context through APIs or backend services.
-Rejected Because
-This approach cannot reliably represent transient frontend state.
-Examples include:
-• Unsaved chart edits.
-• Temporary dashboard filters.
-• Active dashboard tabs.
-• SQL editor state.
-• Draft configuration changes.
-As a result, chatbot context would frequently drift from what the user is actually viewing.
-Decision
-Option B is selected.
-The host owns context normalization while extensions own context composition.
-This preserves separation of concerns, minimizes coupling, and provides a stable foundation for future extension capabilities.
-6.3 D2 — Singleton Chatbot Resolution
-When multiple chatbot extensions are installed, the host must determine which chatbot is rendered.
-This decision shapes both the rendering model and the extension isolation model.
-Option A — Expose Providers Through getViews()
-Allow:
-getViews(location);
-to return both metadata and rendering providers.
-Rejected Because
-Rendering providers are executable logic.
-Exposing providers would allow one extension to:
-• Render another extension.
-• Bypass host lifecycle management.
-• Circumvent fault isolation.
-• Assume ownership of another extension's UI.
-This violates a deliberate separation between extension discovery and extension execution.
-Option B — Host-Managed Provider Resolution (Selected)
-The host exposes only metadata publicly while retaining provider resolution internally.
-Conceptually:
-const provider = getViewProvider("superset.chatbot", selectedId);
-Chatbot selection is handled through a host-managed policy:
-const chatbot = getActiveChatbot(adminSelectedId, enabledMap);
-Advantages
-• Preserves extension isolation.
-• Preserves host ownership of rendering.
-• Supports administrative selection.
-• Supports enablement checks.
-• Supports future policy evolution.
-Option C — Reuse resolveView()
-Use the existing rendering helper:
-resolveView(id);
-to render chatbot providers.
-Rejected Because
-resolveView() assumes the caller already knows which view should be rendered.
-It does not account for:
-• Administrative selection.
-• Enablement state.
-• Settings synchronization.
-• Chatbot-specific resolution policy.
-Decision
-Option B is selected.
-The host owns chatbot selection and rendering.
-The registry remains a discovery mechanism rather than a rendering mechanism.
-Architectural Principle
-A core principle established by this SIP is:
-"Extensions may discover registered views, but only the host may render registered views."
-This preserves extension isolation and prevents cross-extension rendering dependencies.
-6.4 D3 — Descriptor Metadata Ownership
-Chatbot registrations may include metadata used by administrative and discovery interfaces.
-A key question is whether descriptor metadata should be static or runtime-updatable.
-
-Option A — Static Descriptor Metadata (Selected)
-Metadata is defined at registration time and remains unchanged for the lifetime of the registration.
-Example:
-{
-id: 'acme.chatbot',
-name: 'Acme Chatbot',
-icon: 'Bubble',
-}
-Advantages
-• Simpler registry implementation.
-• Clear ownership model.
-• Consistent administration UI.
-• No registry update lifecycle.
-Option B — Runtime-Updatable Metadata
-Extensions can update descriptor metadata after registration.
-Examples:
-• Notification badges.
-• Thinking indicators.
-• Dynamic branding.
-Rejected Because
-These states belong to the chatbot user interface rather than the registration descriptor.
-Supporting dynamic metadata would:
-• Increase registry complexity.
-• Introduce update synchronization concerns.
-• Provide limited benefit for current consumers.
-Decision
-Option A is selected.
-Descriptor metadata remains static.
-Dynamic UI state remains the responsibility of the chatbot component.
-Future requirements for dynamic metadata can be addressed independently if needed.
-6.5 D4 — Administration Scope
-This SIP introduces deployment-wide chatbot administration.
-A key question is whether availability should be deployment-scoped or user-scoped.
-Option A — Deployment-Wide Administration (Selected)
-Administrators manage:
-• Extension availability.
-• Default chatbot selection.
-These settings apply to the entire deployment.
-Advantages
-• Clear administrative ownership.
-• Simple operational model.
-• Consistent with existing extension administration patterns.
-• Avoids introducing multiple configuration layers.
-Option B — User-Scoped Availability
-Availability and chatbot selection become user-specific settings.
-Rejected Because
-Administrative availability and user preference represent different concerns.
-Administrators answer:
-"Which integrations are available in this deployment?"
-Users answer:
-"Which available integrations do I prefer?"
-Combining these concerns into a single model creates unclear ownership and duplicated configuration responsibilities.
-
-Decision
-Option A is selected.
-This SIP introduces only deployment-wide administration.
-Future user preferences should be layered on top using the following model:
-Effective Availability = Deployment Availability AND User Preference
-The recommended persistence mechanism for user-specific preferences is the Extension Storage API.
-This approach aligns with SIP-127 and preserves a clear separation between administrative configuration and user customization.
-
-7. Risks and Future Considerations
-The selected architecture introduces several tradeoffs.
-Namespace Maintenance
-As additional application surfaces become extension-aware, new namespaces may be required.
-This increases the maintenance burden of the extension API surface.
-Contract Evolution
-Namespace contracts are intended to be stable.
-Over time, extensions may require additional context that is not initially exposed.
-Future additions must preserve compatibility and avoid leaking implementation details.
-Context Growth
-Dashboard and chart context may become increasingly rich over time.
-Care must be taken to ensure context APIs remain focused and do not evolve into large aggregate objects.
-Extension Expectations
-Chatbot vendors may request direct access to internal application state for convenience.
-This SIP intentionally rejects that approach in favor of stable semantic contracts.
-Maintaining that boundary may require additional namespace evolution over time. 8. Open Questions
-D5 — Per-Page Visibility
-Should chatbot extensions be able to declare page visibility constraints?
-Two approaches remain possible.
-Extension-Controlled Visibility
-Extensions observe:
-navigation.onDidChangePage(...)
-and decide whether to render themselves.
-Host-Enforced Visibility
-Extensions declare supported page types through manifest metadata and the host enforces visibility.
-Recommendation
-Defer this decision.
-The current architecture already supports extension-controlled visibility without requiring additional platform capabilities.
-
-D6 — Generalized Floating Contribution Areas
-The current proposal introduces a chatbot-specific contribution location:
-superset.chatbot
-A future question is whether this should evolve into a more generic floating-widget framework.
-Examples might include:
-• Chatbots.
-• Guided tours.
-• Notification centers.
-• Productivity assistants.
-Recommendation
-Keep the contribution area chatbot-specific.
-If broader floating-widget requirements emerge, introduce a dedicated abstraction rather than expanding the scope of this SIP.
-

-# Security Policy
-
-This is a project of the [Apache Software Foundation](https://apache.org) and follows the
-ASF [vulnerability handling process](https://apache.org/security/#vulnerability-handling).
-
-## Reporting Vulnerabilities
-
-**⚠️ Please do not file GitHub issues for security vulnerabilities as they are public! ⚠️**
-
-
-Apache Software Foundation takes a rigorous standpoint in resolving the security issues
-in its software projects. Apache Superset is highly sensitive and forthcoming to issues
-pertaining to its features and functionality.
-If you have any concern or believe you have found a vulnerability in Apache Superset,
-please get in touch with the Apache Superset Security Team privately at
-e-mail address [security@superset.apache.org](mailto:security@superset.apache.org).
-
-More details can be found on the ASF website at
-[ASF vulnerability reporting process](https://apache.org/security/#reporting-a-vulnerability)
-
-**Submission Standards & AI Policy**
-
-To ensure engineering focus remains on verified risks and to manage high reporting volumes, all reports must meet the following criteria:
-- Plain Text Format: In accordance with Apache guidelines, please provide all details in plain text within the email body. Avoid sending PDFs, Word documents, or password-protected archives.
-- Mandatory AI Disclosure: If you utilized Large Language Models (LLMs) or AI tools to identify a flaw or assist in writing a report, you must disclose this in your submission so our triage team can contextualize the findings.
-- Human-Verified PoC: All submissions must include a manual, step-by-step Proof of Concept (PoC) performed on a supported release. Raw AI outputs, hypothetical chat transcripts, or unverified scanner logs will be closed as Invalid.
-
-We kindly ask you to include the following information in your report to assist our developers in triaging and remediating issues efficiently:
-- Version/Commit: The specific version of Apache Superset or the Git commit hash you are using.
-- Configuration: A sanitized copy of your `superset_config.py` file or any config overrides.
-- Environment: Your deployment method (e.g., Docker Compose, Helm, or source) and relevant OS/Browser details.
-- Impacted Component: Identification of the affected area (e.g., Python backend, React frontend, or a specific database connector).
-- Expected vs. Actual Behavior: A clear description of the intended system behavior versus the observed vulnerability.
-- Detailed Reproduction Steps: Clear, manual steps to reproduce the vulnerability.
-
-## Security Model
-
-This section defines what Apache Superset considers a security issue and what it does not. It is the canonical reference for reporters, the Apache Superset Security Team, and any automated tool (LLM-based scanner, static analyzer, dependency tool) that needs to constrain its hypotheses to behaviors that genuinely violate the project's security policy.
-
-The model is intentionally written in terms of principals, trust boundaries, and capability surface rather than in terms of specific files, functions, or libraries. New code paths inherit the model automatically.
-
-### Trust Boundaries
-
-Apache Superset's threat model assumes three trust boundaries.
-
-1. *The Admin role* is a fully trusted operational principal. Anything an Admin can do through the documented user interface, REST API, or configuration system is an intended capability, not a vulnerability, even if individually powerful or destructive. The Admin role is, by policy, equivalent to operating-system-level trust over the Apache Superset application. This is unavoidable rather than aspirational: an Admin can, for example, register new database connections of arbitrary type, execute arbitrary SQL through SQL Lab, render Jinja templates that resolve to SQL or rendered HTML, and override application configuration. Granting Admin is functionally equivalent to granting shell access on the host, which is the reasoning behind treating it as a trust boundary in the sense of MITRE CNA Operational Rules 4.1.
-
-2. *The operator* is whoever deploys, configures, and runs Apache Superset. Behaviors that depend on deployment-time decisions are the operator's responsibility, not Apache Superset's. This includes the values of secrets, the network reachability of the application and its data sources, the choice of database connectors and cache backends, the selection of feature flags, the destinations of notifications, and the trust placed in third-party plugins. Defaults that fail closed are the responsibility of the Apache Superset codebase. Defaults that fail open must be accompanied by a documented hardening requirement; applying that hardening is the operator's responsibility, while shipping an undocumented or unflagged fail-open default is a codebase issue.
-
-3. *The Apache Superset codebase* is responsible for enforcing the role and capability matrix below across its product surface. A failure to enforce, anywhere in that surface, is in scope. The codebase's commitments are limited to the role and capability matrix and to controls Apache Superset's own documentation (this file and the linked Security documentation) explicitly positions as security boundaries; configurable hardening that operators can layer on top is treated separately under *Vulnerability Scope* below.
-
-### Roles and Capabilities
-
-Apache Superset ships with the following first-class principals. Detailed permission definitions live in the [Security documentation](https://superset.apache.org/docs/security).
-
-| Principal | Read data | Write objects | Execute SQL | Manage databases | Manage users, roles, RLS |
-|---|---|---|---|---|---|
-| Public (anonymous) | none by default | no | no | no | no |
-| Gamma | only granted datasets | own charts and dashboards on granted datasets | no by default (requires the `sql_lab` role) | no | no |
-| Alpha | all data sources | own charts, dashboards, and datasets | no by default (requires the `sql_lab` role) | data upload to existing databases only | no |
-| Admin | all | all | yes | yes | yes |
-| Embedded guest token | data sources reachable through the embedded dashboards the token authorizes | no | no | no | no |
-
-The `sql_lab` role is *additive*: it grants the SQL Lab permission set on top of the base role above, and is the only path by which Gamma or Alpha gain SQL execution capability. Database access is still scoped per the base role's grants. Admin includes SQL Lab access by default.
-
-Deployments may grant or revoke individual view-menu permissions, which shifts the boundary for that deployment but does not redefine the model. Any custom role created by an operator inherits the same principle: its capabilities are whatever the operator has explicitly granted it. The Public principal follows the same rule: operators may grant the Public role read access to specific datasets or dashboards (typically for anonymous reporting use cases), which shifts the boundary for that deployment without redefining the model.
-
-### Vulnerability Scope
-
-The test for whether a finding is in scope is a single question:
-
-> *Does this finding let a principal perform an action the role and capability matrix above does not entitle them to?*
-
-If yes, it is in scope. If no, it is out of scope. The lists below apply that test to the classes Apache Superset most commonly receives reports about; they are illustrative, not exhaustive.
-
-*In Scope*
-
-- A user, embedded guest, or anonymous visitor reads, modifies, or deletes data outside their granted set. Includes object-level access bypass on charts, dashboards, datasets, saved queries, tags, annotations, and similar per-object endpoints, and row-level-security rule bypass.
-- A user supplies input that the codebase should sanitize or parameterize but does not, causing arbitrary SQL, template code, or scripts to execute. Includes injection through Jinja templates, SQL-construction paths, and any field the codebase passes to a query engine or template engine.
-- A user bypasses authentication, fixates or reuses another user's session, or reaches an authenticated endpoint without logging in.
-- An embedded guest token authorizes actions outside the dashboard it was issued for, or can be forged, replayed, or escalated to a higher principal.
-- Apache Superset, acting on behalf of an unprivileged user, fetches an outbound URL the user controls in a feature where Apache Superset itself, not the operator, controls the outbound destination set (server-side request forgery).
-- An Apache Superset default fails open without an accompanying documented hardening requirement. The codebase is responsible for shipping fail-closed defaults or for documenting the hardening required when a default fails open; failures of that responsibility are in scope (see *Trust Boundaries*).
-- A user bypasses a control Apache Superset documents specifically as a security boundary. This includes row-level security, the access checks tied to the role and capability matrix above, and any feature whose documentation positions it as security-relevant. The codebase commits to enforcing those controls; bypasses are in scope regardless of which principal triggers them.
-- A user causes a script to execute in another user's browser through a field the codebase renders to that other user (cross-site scripting), or causes cross-origin leakage of authenticated session state or data.
-- A user reaches a route, page, or API endpoint that requires a role they do not have.
-
-*Out of Scope*
-
-- Any action an Admin role can perform through documented configuration, API, or UI. The Admin role is a trusted operational principal by policy. Per MITRE CNA Operational Rules 4.1, a qualifying vulnerability must violate a security policy; behavior within a documented trust boundary does not.
-- Deployment or operator decisions: the values of secrets and tokens, whether internal networks are reachable from the server, which database connectors or cache backends are enabled, which feature flags are set, where notifications are delivered, and which third-party plugins are loaded.
-- Compromise, modification, or malicious control of trusted backend infrastructure. Apache Superset assumes the integrity of its metastore, cache backends (for example Redis or Memcached), message brokers, secret stores, and other operator-managed infrastructure. Findings that require an attacker to read from, write to, or otherwise tamper with these systems, including injecting malicious state, serialized objects, cache entries, task metadata, configuration, or database records, are post-compromise scenarios and do not constitute vulnerabilities in Apache Superset itself. A finding remains in scope only if an unprivileged user can cause such modification through a vulnerability in Apache Superset.
-- Code paths whose intended purpose is example data, demos, fixtures, local development, or documentation, rather than the production runtime.
-- How a downstream application (spreadsheet program, email client, browser handling user-downloaded files) interprets output Apache Superset produced for it.
-- Findings without a reproducible proof of concept against a supported release. The burden of demonstrating exploitability rests with the reporter; findings closed for lack of a proof of concept may be refiled if one is later produced.
-- Brute force, rate limiting, denial of service, or resource exhaustion that does not bypass a documented control.
-- Missing security headers, banner or version disclosure, user or object enumeration through error messages or timing, and similar low-impact information disclosure that does not enable a further concrete exploit.
-- Bypasses of configurable defense-in-depth hardening that Apache Superset does not document as a security boundary. Apache Superset is not a SQL or database firewall: operator-deployable filters such as SQL function or table denylists, URI restrictions on already-authorized database connectors, and similar belt-and-braces controls are provided to let operators layer hardening on top of the role and capability matrix, not as firewall-grade guarantees the codebase commits to. Findings against such hardening are improvements, not vulnerabilities, unless the documentation positions the specific control as security-relevant.
-- Hardening suggestions that improve defense in depth but do not violate the security model.
-
-Findings in third-party dependencies fall into two cases. A finding in a transitive dependency, or in an operator-selected dependency that Apache Superset does not ship, is out of scope and should be reported to the dependency's maintainers. A finding caused by Apache Superset pinning a known-vulnerable version of a direct dependency it ships, or using a dependency in a way that creates a vulnerability the dependency itself does not have, remains in scope. Dependency findings in the official Apache Superset Docker image that fall into the first case can be remediated by extending the image at release time.
-
-When uncertain whether a finding falls in scope, please file it through the reporting process above. The triage team will classify it and explain the reasoning if it is closed as out of scope.
-
-**Outcome of Reports**
-
-Reports that are deemed out of scope for a CVE but represent valid security best practices or hardening opportunities are typically converted into public GitHub issues, where the community can contribute fixes alongside the maintainers. The triage decision and reasoning are communicated back to the reporter in either case.
-
-**Vulnerability Aggregation & CVE Attribution**
-
-In accordance with MITRE CNA Operational Rules (4.1.10, 4.1.11, and 4.2.13), Apache Superset issues CVEs based on the underlying architectural root cause rather than the number of affected endpoints or exploit payloads.
-- Aggregation: If multiple exploit vectors stem from the same programmatic failure or shared vulnerable code, they must be aggregated into a single, comprehensive report.
-- Independent Fixes: Separate CVEs will only be assigned if the vulnerabilities reside in decoupled architectural modules and can be fixed independently of one another.
-Reports that fail to aggregate related findings will be merged during triage to ensure an accurate and defensible CVE record.
-
-**Your responsible disclosure and collaboration are invaluable.**

-# Chatbot Extensions — Tickets
-
-Lightweight, pre-implementation tickets. Each says what to build and where the
-boundaries are; it does not prescribe the final code. Stack order (bottom → top):
-contribution point → frontend API mount → eager loading → admin UI → backend
-settings/permissions → context sharing → import/delete.
-
----
-
-## 1. Define the contribution point
-
-**Goal:** Introduce the `superset.chatbot` contribution area and the host plumbing
-needed to mount a single chatbot at the application-shell level, persistent across
-routes. This is the keystone everything else builds on.
-
-**Build:**
-
-- Register `superset.chatbot` as a recognized contribution location in the view
-  registry.
-- Add an app-shell / app-root contribution scope to the extension manifest schema
-  so the location can be declared in `extension.json` (the current schema is
-  SQL-Lab-only). Teach both manifest validation and runtime registration about it.
-- Provide an exclusive-location resolver that selects exactly one renderable
-  chatbot for the slot, with a deterministic first-to-register fallback and a seam
-  for an externally supplied "active chatbot id" (so admin/runtime policy can plug
-  in later without touching the resolver).
-- Host-managed mount layout: fixed bottom-right, 24px margin, z-index above content
-  and toasts, below modals.
-
-**Out of scope:** fault isolation, admin selection UI, the lifecycle/teardown
-contract, eager loading, streaming, context namespaces, authoring docs.
-
-**Depends on:** nothing — this unblocks the rest.
-
-**Done when:** an extension can register at `superset.chatbot` and render at the
-app shell across routes; the resolver returns one provider (admin-id seam +
-first-to-register fallback); unregistering removes the mount cleanly with no
-duplicate bubbles.
-
-Base branch: `enxdev/chat-prototype`
-
-**External Links:** https://github.com/apache/superset/pull/40439
-
----
-
-## 2. Host resolution & mount (frontend API entry point)
-
-**Goal:** Turn a registered `superset.chatbot` view into a rendered, fault-isolated
-bubble — the host-internal provider accessor, the selection policy, and the
-fixed-position mount.
-
-**Build:**
-
-- Host-internal accessors on the views registry: `getViewProvider(location, id)`
-  and `getRegisteredViewIds(location)`. Keep the public `getViews` descriptor-only —
-  do not expose providers on the public surface.
-- A registry change subscription so a mount can re-resolve without polling (fired
-  on register/unregister).
-- The `getActiveChatbot(adminSelectedId?, enabledMap?)` resolver implementing the
-  selection policy: empty → none; drop disabled ids; admin-selected-and-enabled
-  wins; else first enabled in registration order.
-- A `ChatbotMount` component at the app shell that renders the active provider
-  inside the host `ErrorBoundary`, re-resolves on registry change, and renders
-  nothing when no chatbot is active.
-
-**Out of scope:** the contribution location itself (#40439); eager-loading the
-bundle (#40441); the settings endpoint (#40443, consumed here with silent
-fallback); admin UI; the lifecycle/teardown contract.
-
-**Depends on:** #40439 (imports `CHATBOT_LOCATION`). The settings endpoint is a soft
-forward-dependency — the mount falls back to first-registered-enabled if it 404s.
-
-**Done when:** the provider accessor and resolver behave per the policy; the mount
-renders/clears correctly and survives a throwing provider via `ErrorBoundary`;
-`getViews` stays descriptor-only.

----
-
-## 3. Eager loading & extension lifecycle/teardown
-
-> Merged: this ticket also covers the **lifecycle & teardown contract** — both are
-> implemented in the same PR (#40441), so they are tracked together.
-
-**Goal:** Boot extension bundles at app-shell startup so contributions register
-before the first route, and define the host contract for tearing those
-contributions down on uninstall.
-
-**Build — eager loading:**
-
-- An `ExtensionsStartup` component that, once the session is confirmed and behind
-  `FeatureFlag.EnableExtensions`, kicks off `initializeExtensions()` in the
-  background. The host renders immediately; the mount re-resolves reactively when
-  registrations land.
-- Wire `window.superset` so Module-Federation remotes can consume host namespaces.
-- Mount `<ChatbotMount />` as a sibling of the route switch, inside
-  `ExtensionsStartup`.
-- On bundle-load failure: a danger toast, host stays interactive, corner stays
-  empty. Add a global `unhandledrejection` logger (log only; do not suppress the
-  browser default).
-
-**Build — lifecycle/teardown contract (Model A1, per-contribution dispose):**
-
-- During the `./index` factory call, intercept the public registrars and collect
-  the returned `Disposable`s keyed by extension id.
-- `deactivateExtension(id)` is the single teardown entrypoint: it fires every
-  collected `Disposable` and removes the extension from the index. A throwing
-  `Disposable` must not block the others (catch per-disposable). Idempotent;
-  unknown id is a no-op.
-- Trigger semantics to document: **uninstall** → `deactivateExtension(id)`;
-  **disable** → mount filters by `enabledMap`, does NOT fire disposables, re-enable
-  needs no reload; **replace** (singleton) → resolver re-selects, the losing
-  extension is not deactivated. Disposal order is best-effort (registration order),
-  not a contract — consumers must be order-independent.
-
-**Out of scope:** selective per-type eager loading (not feasible without running the
-factory); the mount-boundary `ErrorBoundary` (#40440); the settings endpoint and
-its subscription primitive (#40443); context namespaces (#40444); an async-aware
-`deactivate(): Promise<void>` — file separately only if a graceful-flush
-requirement appears.
-
-**Depends on:** #40440 (`ChatbotMount`, resolver, registry-subscription hook). Soft
-build-time deps on #40443 (settings subscription) and #40444 (namespaces) — land
-those first or stub the imports.
-
-**Done when:** enabled extensions init once at startup behind the flag without
-gating initial render; the bubble appears reactively on registration;
-`deactivateExtension(id)` disposes all of an extension's contributions (per-disposable
-catch, idempotent); load failure toasts without throwing; teardown is verified
-end-to-end on the reference chatbot (including an abort-registry controller that must
-still abort on deactivate).

-
-## 4. Admin configuration UI
-
-**Goal:** Let an admin enable/disable the chatbot and, when more than one chatbot is
-installed, choose which is active.
-
-**Resolve before building:**
-
-- Is "disable the chatbot" the existing generic extension-disable, or a
-  chatbot-specific toggle? (Determines the ticket's size — prefer reusing the
-  existing flag.)
-- Where does the UI live? Default: the existing extensions management surface, not a
-  new page.
-- How does the "default chatbot" selection persist? Reuse existing extension-state
-  storage or a config value — do not invent a table.
-- Which permission gates it? Default: the existing Extensions-API write permission.
-
-**Build:**
-
-- Enable/disable control that empties the `superset.chatbot` slot when off (no broken
-  placeholder).
-- (Gated on the singleton-policy decision) A selection control listing candidates via
-  `getViews('superset.chatbot')`, activating the choice through the resolver, falling
-  back to first-to-register when unset.
-- Switching the active chatbot or disabling it at runtime must dispose the previously
-  active chatbot via its `Disposable` and release its in-flight stream readers (via
-  `AbortController`) — no two bubbles, no leaked readers.
-
-**Out of scope:** the singleton-policy decision itself; per-page visibility; the
-resolver implementation (consumed here).
-
-**Depends on:** #40440 (resolver) for selection; enable/disable does not wait on the
-policy decision.
-
-**Done when:** admin can enable/disable (gated by the chosen permission) and the slot
-empties when off; selection picks the active chatbot with first-to-register fallback;
-the persistence-mechanism and permission decisions are recorded in the ticket.

-
-## 5. Permissions
-
-**Goal:** Guarantee the new page-context surface cannot expose anything the current
-user can't already access through Superset's standard security model. Chatbot
-extensions fetch data as any other frontend surface and inherit only the current
-user's privileges; this ticket covers only the new host → extension context-sharing
-path.
-
-**Build:**
-
-- The page-context namespaces (#40444) must derive entity metadata from the same
-  permission checks that gate the underlying page — not a raw Redux pass-through.
-- Canonical threat (SIP §2.1): a dashboard the user can view that contains a chart
-  whose dataset they cannot query — that chart's metadata (id, name, datasource,
-  viz type, form_data) must be dropped from the context payload.
-- Context carries only lightweight semantic data + identifiers that resolve through
-  already-protected APIs; never inline dataset rows or query results.
-- Filtering applies equally to the initial read and every change-notification
-  payload. A chatbot an admin has disabled receives no context at all.
-
-**Out of scope:** REST API authorization, RBAC, RLS (already enforced by Superset);
-LLM/backend auth; the singleton selection policy. The chatbot authenticates via the
-user's existing session (cookie + CSRF) — no separate credential is issued.
-
-**Depends on:** the Spike sizing the new namespaces (the per-getter filtering lands
-with those getters); the Context-sharing ticket consumes the filtered getters this
-one specifies.
-
-**Done when:** context never exposes entities/ids/metadata the user can't access
-(even via a manually-entered URL); the dashboard payload omits charts whose dataset
-the user can't query; no inline privileged payloads; filtering covers change events
-as well as the initial read; a disabled chatbot gets nothing.
-
-Base branch: `enxdev/chat-prototype`
-
-**External Links:** https://github.com/apache/superset/pull/40443
-
----
-
-## 6. Context sharing
-
-**Goal:** Let the chatbot read semantic page context and subscribe to changes through
-public per-surface core namespaces only — never the host Redux store.
-
-**Approach:** Deliver context through per-surface namespaces — the existing `sqlLab`
-namespace plus new `dashboard` / `explore` / `navigation` namespaces that mirror its
-shape (a state getter + an `Event<T>` change subscription). No new aggregate context
-API. The new namespaces copy `sqlLab`'s shape but must filter the Redux state they
-read (the permission filtering itself is specified by #40443).
-
-**Build:**
-
-- Route all chatbot page-context reads through one narrow adapter module with a fixed
-  interface — the adapter is the deliverable, not scattered call sites — so swapping
-  to core namespaces is a one-line change.
-- Back the adapter with `sqlLab` immediately; back the dashboard/explore/navigation
-  portions and wire change notifications through `navigation`'s page-change event once
-  those namespaces ship.
-
-**Out of scope:** the permission-filtering logic (#40443 + upstream namespace work);
-designing the namespace API surface (upstream OSS work, sized by the Spike).
-
-**Depends on:** a Spike to size the new namespaces (state getters + events + the
-per-getter permission filtering). The namespace _shape_ is settled by the `sqlLab`
-precedent; the filtering is real design work.
-
-**Done when:** all context reads go through the single adapter (zero direct Redux
-imports, greppable); SQL Lab context works today; dashboard/explore context is either
-delivered or explicitly tracked as OSS-blocked (not faked); change notifications need
-no polling; no extra host re-renders.

-
-**External Links:** https://github.com/apache/superset/pull/40444
-
----
-
-## 7. Import / delete UI
-
-**Goal:** Add an actions column to the extensions list with buttons to delete an
-extension, set-as-default (chatbot extensions only), and import a new extension.
-
-**Build:**
-
-- Import an extension bundle, refreshing the list on success.
-- Delete an installed extension.
-- A "set as default chatbot" control, shown only for chatbot extensions.
-
-**Out of scope:** the settings endpoint itself (#40443); the resolver (#40440).
-
-**Depends on:** #40442/#40443 for the settings + chatbot-selection plumbing.
-
-**Done when:** an admin can import, delete, and set a default chatbot from the
-actions column, with the list reflecting changes.
-
-Base branch: `enxdev/chat-prototype`
-
-**External Links:** https://github.com/apache/superset/pull/40450
-
----
-
-## ~~8. Fault isolation & error boundaries~~ — CLOSED (no ticket needed)
-
-The protective fault-isolation mechanisms are **already implemented** across the
-mount and eager-loading PRs, so no standalone ticket is required:
-
-- Render/lifecycle throw → host `ErrorBoundary` around the `superset.chatbot` slot
-  (#40440, reinforced by the `ChatbotRenderer` wrapper in #40441).
-- Bundle-load failure → `.catch()` + danger toast in `ExtensionsLoader` (#40441).
-- `activate()` throw → host try/catch in `ExtensionsLoader` (#40441).
-- Escaped async rejection → `unhandledrejection` hook in `ExtensionsStartup` (#40441).
-- Failed-activation cleanup → driven by `deactivateExtension` (ticket 3 / #40441).
-
-The host stays safe under every failure class today. The only unbuilt pieces were the
-**optional** "chatbot failed — Reload page" notification and structured
-failure-class/telemetry logging — both judged not worth a ticket (the original spec
-itself marked the reload notification "optional"). File a fresh ticket only if that
-UX is later wanted.
-
-(Original link, for reference only: PR #40433 `feat(extensions): adds chatbot P1-P2` —
-closed/superseded; never a dedicated fault-isolation PR.)
-
----
-
-## Notes on consolidation
-
-- **Lifecycle/teardown** was a separate ticket pointing at the same PR as **Eager
-  loading** (#40441) — merged into ticket 3 above. (This is the only true duplicate.)
-- The **Permissions** ticket (#40443) is kept as-is. Note its PR also contains
-  backend settings-persistence code, but the original ticket only ever scoped the
-  permission-safe context surface — so the ticket stays "Permissions" and no
-  persistence ticket is invented.
-- The **Permissions** ticket previously had a truncated base branch
-  (`enxdev/chat-protot`) — corrected to `enxdev/chat-prototype`.
-- **Fault isolation** was **closed without a ticket** (see the struck-through section
-  above): its protective mechanisms already shipped in #40440/#40441, and the only
-  unbuilt pieces (the optional "Reload page" notification + structured telemetry
-  logging) were judged not worth a ticket.

-### Dataset import validates catalog against the target connection
-
-Importing a dataset now validates the `catalog` field against the target database connection. When the connection has multi-catalog disabled (`allow_multi_catalog` off) and the dataset's catalog is not the connection's default catalog, the import fails instead of silently persisting the non-default catalog. This matches the validation already enforced on the dataset update path and prevents imported datasets from querying an unintended database.

-If you relied on importing datasets with a non-default catalog, enable "Allow changing catalogs" on the target connection, or set the dataset's catalog to the connection's default before importing.

-### Backfilling missing translations with AI
-
-For languages with many untranslated strings, the repo includes a script that
-uses Claude AI to generate draft translations for any missing entries. All
-AI-generated strings are marked `#, fuzzy` and tagged with an attribution
-comment so that human reviewers know they need to be checked before merging.
-
-#### Prerequisites
-
-```bash
-pip install -r superset/translations/requirements.txt
-```
-
-Claude Code must be installed and authenticated (`claude --version` should
-work). The script calls `claude -p` internally — no separate API key is needed.
-
-#### Step 1 — Build the translation index
-
-The index captures every already-translated string in every language and
-serves as cross-language context for the AI. Rebuild it whenever `.po` files
-change significantly:
-
-```bash
-python scripts/translations/build_translation_index.py
-# Writes: superset/translations/translation_index.json
-```
-
-#### Step 2 — Preview with a dry run
-
-Check what would be translated without writing anything:
-
-```bash
-python scripts/translations/backfill_po.py --lang fr --limit 20 --dry-run
-```
-
-Output shows each string, its translation, and a context tag:
-- No tag — 3+ reference languages available (high confidence)
-- `[ctx:N]` — only N other languages have this string (lower confidence)
-- `[ctx:0]` — no other language has this string yet; English alone used
-
-#### Step 3 — Run the backfill
-
-```bash
-python scripts/translations/backfill_po.py --lang fr
-```
-
-Options:
-
-| Flag | Default | Description |
-|------|---------|-------------|
-| `--lang LANG` | required | ISO language code (`fr`, `de`, `ja`, …) |
-| `--batch-size N` | 50 | Strings per Claude request |
-| `--limit N` | unlimited | Stop after N entries |
-| `--min-context N` | 0 | Skip entries with fewer than N reference translations |
-| `--model MODEL` | `claude-sonnet-4-6` | Claude model to use |
-| `--dry-run` | off | Print without writing |
-| `--no-fuzzy` | off | Don't mark entries as fuzzy |
-
-Use `--min-context 2` to skip strings that have fewer than 2 reference
-translations in other languages. Those strings are more likely to be ambiguous
-(short labels, UI fragments) where the correct meaning can't be inferred
-without additional context.
-
-#### Step 4 — Review and commit
-
-Open the target `.po` file and search for `fuzzy`. For each generated entry:
-
-1. Verify the translation is correct for the UI context.
-2. Remove the `# Machine-translated via backfill_po.py` comment and the
-   `#, fuzzy` flag line once you are satisfied.
-3. If the translation is wrong, correct the `msgstr` before removing the flag.
-4. Commit the `.po` file — do **not** commit `translation_index.json` (it is
-   gitignored and regenerated locally).
-
-#### Running via npm
-
-From `superset-frontend/`:
-
-```bash
-# Rebuild index
-npm run translations:build-index
-
-# Backfill (pass arguments after --)
-npm run translations:backfill -- --lang fr --dry-run
-```

-# Reference Chatbot Extension
-
-Canonical environment-validation extension for the `superset.chatbot`
-contribution area. **Not** a product chatbot — there is no LLM, no backend,
-no persistence. Its purpose is to exercise the extension platform end-to-end:
-
-- `views.registerView` at `superset.chatbot` (singleton resolution)
-- Lifecycle activation + a master disposable that tears down everything
-- `commands.registerCommand` for `core.chatbot__open|close|toggle`
-- Mock streaming with `AbortController` cancellation on dispose
-- Defense-in-depth React error boundary inside the panel
-- A single P3 page-context seam that lights up automatically as the
-  `dashboard` / `explore` / `dataset` / `navigation` namespaces become
-  available at runtime on the host
-
-It is intended as the reference implementation third-party chatbot extension
-authors copy. Anything that ships as host-internal (the mount point, the
-admin picker, the `getActiveChatbot` resolver) is **not** here — see the
-host side at `superset-frontend/src/components/ChatbotMount/` and
-`superset-frontend/src/core/chatbot/`.

-```
-
-## Run the unit tests
-
-```bash
-cd extensions/chat
-npm install            # first time only
-npx jest
-```
-
-The tests mock `@apache-superset/core` via `src/__tests__/sdkMock.ts` so they
-do not depend on host runtime wiring.
-
-## Build / bundle for deployment
-
-```bash
-# from the extension folder
-npm install
-npm run build
-
-# packaging into a .supx is handled by the Superset extensions CLI
-pip install apache-superset-extensions-cli
-superset-extensions bundle    # produces apache-superset.reference-chatbot-0.1.0.supx
-```
-
-Drop the `.supx` into the `EXTENSIONS_PATH` of a Superset instance that has
-`FEATURE_FLAGS = { "ENABLE_EXTENSIONS": True }`.
-
-## Selecting it as the active chatbot
-
-The host's singleton picker reads `active_chatbot_id` from the admin
-settings endpoint (`/api/v1/extensions/settings`). Set it to:
-
-```
-apache-superset.reference-chatbot
-```
-
-If no admin selection exists, the host falls back to the first-to-register
-chatbot — installing this extension alone is enough for the bubble to appear.
-
-## P3 integration seams
-
-All page-context derivation lives in [`src/context/pageContext.ts`](src/context/pageContext.ts).
-Each namespace branch (`dashboard`, `explore`, `dataset`, `navigation`) is
-called defensively — when the host implementation lands, the returned value
-becomes non-undefined automatically with no other change in the extension.
-
-The panel re-reads context on `popstate`. Once `navigation.onDidChangePage`
-is live on the host, the panel's `useEffect` should subscribe to it instead;
-that is the only file in the extension that needs to change for full P3
-context sync.
-
-## Known intentional non-features
-
-- No conversation persistence — by design (extension scope per SIP §2).
-- No real network. The mock stream is a `setTimeout` token emitter so the
-  cancellation contract is exercised without external dependencies.
-- No keyboard shortcut binding (Cmd+K). Extensions own that, but it adds
-  surface area not needed for platform validation.
-- No notification badge / icon mutation. SIP §3.2 recommends static icons;
-  the bubble re-renders freely already.
-
-## TODOs
-
-- **P1**: if/when the host gains `deactivate(): Promise<void>`, wrap the
-  master disposer in `activate.ts` to flush async work before returning.
-- **P3**: replace the `popstate` listener in `Panel.tsx` with
-  `navigation.onDidChangePage` once that event is wired up host-side.
-- **P4**: if the host pre-registers `core.chatbot__*` as host-owned intents,
-  swap `commands.registerCommand` for the implementation hook in
-  `commands.ts`. Command IDs do not change.

-# Reference Chatbot Extension
-
-Canonical environment-validation extension for the `superset.chatbot`
-contribution area. **Not** a product chatbot — there is no LLM, no backend,
-no persistence. Its purpose is to exercise the extension platform end-to-end:
-
-- `views.registerView` at `superset.chatbot` (singleton resolution)
-- Lifecycle activation + a master disposable that tears down everything
-- `commands.registerCommand` for `core.chatbot__open|close|toggle`
-- Mock streaming with `AbortController` cancellation on dispose
-- Defense-in-depth React error boundary inside the panel
-- A single P3 page-context seam that lights up automatically as the
-  `dashboard` / `explore` / `dataset` / `navigation` namespaces become
-  available at runtime on the host
-
-It is intended as the reference implementation third-party chatbot extension
-authors copy. Anything that ships as host-internal (the mount point, the
-admin picker, the `getActiveChatbot` resolver) is **not** here — see the
-host side at `superset-frontend/src/components/ChatbotMount/` and
-`superset-frontend/src/core/chatbot/`.

-```
-
-## Run the unit tests
-
-```bash
-cd extensions/chat
-npm install            # first time only
-npx jest
-```
-
-The tests mock `@apache-superset/core` via `src/__tests__/sdkMock.ts` so they
-do not depend on host runtime wiring.
-
-## Build / bundle for deployment
-
-```bash
-# from the extension folder
-npm install
-npm run build
-
-# packaging into a .supx is handled by the Superset extensions CLI
-pip install apache-superset-extensions-cli
-superset-extensions bundle    # produces apache-superset.reference-chatbot-0.1.0.supx
-```
-
-Drop the `.supx` into the `EXTENSIONS_PATH` of a Superset instance that has
-`FEATURE_FLAGS = { "ENABLE_EXTENSIONS": True }`.
-
-## Selecting it as the active chatbot
-
-The host's singleton picker reads `active_chatbot_id` from the admin
-settings endpoint (`/api/v1/extensions/settings`). Set it to:
-
-```
-apache-superset.reference-chatbot
-```
-
-If no admin selection exists, the host falls back to the first-to-register
-chatbot — installing this extension alone is enough for the bubble to appear.
-
-## P3 integration seams
-
-All page-context derivation lives in [`src/context/pageContext.ts`](src/context/pageContext.ts).
-Each namespace branch (`dashboard`, `explore`, `dataset`, `navigation`) is
-called defensively — when the host implementation lands, the returned value
-becomes non-undefined automatically with no other change in the extension.
-
-The panel re-reads context on `popstate`. Once `navigation.onDidChangePage`
-is live on the host, the panel's `useEffect` should subscribe to it instead;
-that is the only file in the extension that needs to change for full P3
-context sync.
-
-## Known intentional non-features
-
-- No conversation persistence — by design (extension scope per SIP §2).
-- No real network. The mock stream is a `setTimeout` token emitter so the
-  cancellation contract is exercised without external dependencies.
-- No keyboard shortcut binding (Cmd+K). Extensions own that, but it adds
-  surface area not needed for platform validation.
-- No notification badge / icon mutation. SIP §3.2 recommends static icons;
-  the bubble re-renders freely already.
-
-## TODOs
-
-- **P1**: if/when the host gains `deactivate(): Promise<void>`, wrap the
-  master disposer in `activate.ts` to flush async work before returning.
-- **P3**: replace the `popstate` listener in `Panel.tsx` with
-  `navigation.onDidChangePage` once that event is wired up host-side.
-- **P4**: if the host pre-registers `core.chatbot__*` as host-owned intents,
-  swap `commands.registerCommand` for the implementation hook in
-  `commands.ts`. Command IDs do not change.

-"""Backfill missing translations in a .po file using Claude AI.
-
-For each untranslated (empty msgstr) entry in the target language, the script
-sends the English source string along with all available translations in other
-languages to Claude as context, then writes the AI-generated translation back
-into the .po file marked as #, fuzzy for human review.
-
-Usage:
-  # Build the translation index first (one-time or when .po files change)
-  python scripts/translations/build_translation_index.py
-
-  # Backfill French translations
-  python scripts/translations/backfill_po.py --lang fr
-
-  # Dry run (print what would be translated without writing)
-  python scripts/translations/backfill_po.py --lang de --dry-run
-
-  # Limit to 100 entries and use a specific model
-  python scripts/translations/backfill_po.py --lang es --limit 100 \
-    --model claude-opus-4-6
-
-Options:
-  --lang LANG        ISO language code to backfill (required)
-  --batch-size N     Number of strings per Claude request (default: 50)
-  --limit N          Stop after translating N entries (default: unlimited)
-  --min-context N    Skip entries with fewer than N existing translations across
-                     reference languages (default: 0 — translate everything)
-  --model MODEL      Claude model ID (default: claude-sonnet-4-6)
-  --index PATH       Path to translation_index.json (default: auto-detect)
-  --dry-run          Print translations without writing to .po file
-  --no-fuzzy         Do not mark generated translations as fuzzy (default: mark fuzzy)

-Check that source-code changes don't cause translation regressions.
-
-Usage
------
-Count non-fuzzy translated entries in all .po files and write JSON to stdout:
-
-    python check_translation_regression.py --count
-
-Compare the current .po state against a previously-recorded baseline and fail
-if any language lost translations:
-
-    python check_translation_regression.py --compare /path/to/before.json
-
-Optionally write a markdown report to a file (used by CI to post a PR comment):
-
-    python check_translation_regression.py --compare before.json --report report.md
-
-Use a translations directory other than the repo default (used by CI to count
-against a separate base-branch worktree):
-
-    python check_translation_regression.py --count \\
-        --translations-dir /tmp/base-worktree/superset/translations
-
-Typical CI workflow
--------------------
-1. Create a base-branch worktree alongside the PR worktree
-2. Run babel_update.sh in the base worktree (extract from BASE source)
-3. Record baseline:  python ... --count --translations-dir BASE_TREE > before.json
-4. Run babel_update.sh in the PR worktree (extract from PR source and keep
-   any committed PR .po updates)
-5. Compare:  python ... --compare before.json [--report report.md]
-
-Running babel_update on the base branch first isolates regressions caused by
-the PR's source diff from any pre-existing drift on the base branch, while the
-PR worktree run still allows committed .po updates to restore lost
-translations.
