fix(databricks): support cancelling SQL Lab queries on SEA connections

Databricks queries run through the Python Connector previously had no "stop query" support. The connector's only cancellation mechanism is Cursor.cancel(), which needs a full command identifier from the same backend session; the default Thrift backend's identifier includes a secret that's never exposed via any public/documented accessor, so it can't be reconstructed on the fresh cursor Superset uses to issue cancellation. The newer, opt-in SEA (Statement Execution API) backend uses a plain statement id instead, which can be captured and reused safely, so cancellation is implemented for that case only.

+# Mirror the Docker Hub service-container images that CI relies on into the
+# repository's GitHub Container Registry (GHCR) namespace.
+#
+# WHY: CI jobs declare Postgres/MySQL/Redis/Presto as `services:` containers
+# pulled anonymously from Docker Hub. Anonymous pulls share the runner's IP
+# rate limit, which causes intermittent timeouts / 429s / 502s on `master`
+# and same-repo PRs. The obvious fix — adding `credentials:` to the service
+# blocks — breaks fork PRs hard: forks can't read secrets, so the templated
+# username/password resolve to '' and GitHub rejects the workflow at parse
+# time ("Unexpected value ''"), failing every fork job at "Set up job".
+#
+# Mirroring to GHCR sidesteps both problems: public GHCR images are pulled
+# without Docker Hub's anonymous rate limit AND without any credentials, so
+# the consuming workflows need no `credentials:` block and forks work
+# unchanged.
+#
+# ONE-TIME BOOTSTRAP (maintainer, after this lands on the default branch):
+#   1. Run this workflow once (Actions tab → "Mirror service images to GHCR"
+#      → Run workflow), or wait for the weekly schedule.
+#   2. In the org's Packages settings, set each mirrored package's visibility
+#      to **public** (apache/superset → ci/postgres, ci/mysql, ci/redis,
+#      ci/presto). Public visibility is what lets fork CI pull without auth.
+#   3. Only then merge the follow-up that repoints the `services.*.image`
+#      refs at these GHCR copies and drops the `credentials:` blocks.
+#
+# NOTE: this mirrors only the images declared as `services:` containers (the
+# ones that broke forks). The `bde2020` hive-metastore image pulled via
+# `docker compose` in the Presto/Hive job is a separate path and is left for
+# a follow-up.

+### Scheduled report execution now enforces one application deadline
+
+Scheduled report (not alert) executions are now governed by a single
+end-to-end deadline shared by browser readiness, capture/PDF generation,
+notification delivery, and terminal-state persistence, configured via
+`ALERT_REPORTS_EXECUTION_BUDGET_SECONDS` (with per-phase reserve settings).
+Behavior changes to be aware of:
+
+- The effective budget for a schedule is
+  `min(ALERT_REPORTS_EXECUTION_BUDGET_SECONDS, working_timeout)`. The default
+  budget (one hour) matches the historical `working_timeout` model default,
+  so default installations see no change in how long a report may run —
+  but reports now fail cleanly (with an error notification) at the deadline
+  instead of being killed silently by Celery.
+- For REPORT schedules, the Celery `soft_time_limit`/`time_limit` are now
+  derived from that same effective budget plus
+  `ALERT_REPORTS_EXECUTION_HARD_TIMEOUT_GRACE_SECONDS`, replacing the
+  previous `working_timeout + ALERT_REPORTS_WORKING_TIME_OUT_LAG` /
+  `+ ALERT_REPORTS_WORKING_SOFT_TIME_OUT_LAG` derivation. Alert schedules
+  keep the previous behavior.
+- A `working_timeout` smaller than the summed phase reserves is floored at
+  the minimum viable budget (reserves + 30s) with a warning; such reports
+  fail fast at the first phase check rather than erroring at setup.
+- Dashboard reports whose charts have not mounted are no longer captured
+  blank: readiness is polled until the deadline, and the report fails loudly
+  if charts never mount. Thumbnails and non-report screenshots keep their
+  previous behavior.
+
+### Principal listing APIs now honour related-field filters
+
+Two authorization-related listing behaviors changed for API clients. Neither
+affects the Superset UI — `include_ids` and `security/subject` have no frontend
+callers — but external clients will notice:
+
+- `GET /api/v1/<resource>/related/<column>?include_ids=...` now applies the
+  endpoint's `base_related_field_filters`. Previously the forced IDs were fetched
+  with no filtering, so a caller could resolve principals the related-field
+  filters deliberately hide; those IDs are now omitted from the response.
+- `GET /api/v1/security/subject/` now honours `EXCLUDE_USERS_FROM_LISTS` and
+  `EXTRA_RELATED_QUERY_FILTERS`, matching every other principal-listing endpoint.
+  List counts may drop, and fetching an excluded principal via
+  `GET /api/v1/security/subject/<id>` now returns `404`.
+
+### v1 chart import no longer re-adds the importer as editor on overwrite
+
+Re-importing over an existing chart (an overwrite or a soft-delete restore) no
+longer appends the importing user to the chart's `editors`, matching the
+dashboard importer's behavior. This changes anything only for a user who was not
+already an editor of that chart — typically an admin overwriting a chart they do
+not own, who was previously added as an editor as a side effect of the import.
+Newly-created charts are unaffected.
+### ClickHouse: system sampling queries retry with a bounded read
+
+System-generated sampling queries — filter-value dropdowns, the Samples
+tab/dataset preview, and datetime format detection — that ClickHouse rejects
+with a `max_rows_to_read` error (`TOO_MANY_ROWS`, code 158) are now retried
+once with `SETTINGS read_overflow_mode='break'` appended, so they return a
+partial result bounded by the operator's row cap instead of failing. The retry
+applies only to statements Superset generates for physical-table datasets;
+virtual datasets and user-authored SQL remain fully governed by configured
+read limits, and queries that already succeed are never altered. Operators who
+rely on `max_rows_to_read` as a hard failure gate for these system queries can
+restore the previous behavior per database with
+`"disable_sampling_read_limit_override": true` in the database's Extra JSON.
+Note that a retried query returns partial data with no truncation indicator
+(e.g. a filter dropdown may list only a subset of values on tables above the
+row cap).

+The "Sum as Fraction of Total/Rows/Columns" display options are back as a
+new, standalone **"Show values as"** control (below "Combine metrics" in the
+Options panel), since those were mathematically correct even before this
+change and are unrelated to the totals-correctness fix. A DB migration
+derives the new field from any still-present `aggregateFunction` Sum-fraction
+value, so a chart that had one of those options configured picks the

+Fraction of ..." variants are **not** migrated: they divided a record count,
+while the new control divides the metric's own value, so translating them
+automatically would silently change what the chart displays rather than
+restore it; those charts need to be manually reconfigured if the value-based
+percentage is what's wanted. Charts that used any other non-fraction
+`aggregateFunction` value (Sum, Average, Count, ...) are unaffected, since

+The task ships in the default `CeleryConfig` (both the `superset.tasks.version_history_retention` import and the beat entry). A deployment that overrides `CELERY_CONFIG` without the beat entry logs a startup warning. When the override explicitly defines `imports`, a missing retention module is also reported; an absent `imports` setting is not diagnosed because Celery may register tasks through `include`, autodiscovery, or worker startup imports. Retention only prunes whatever history exists — capture itself is gated separately by `ENABLE_VERSIONING_CAPTURE` (ships off).
+
+### Deletion retention (soft-deleted entities are eventually purged)
+
+Soft-deleted dashboards, charts, and datasets are now permanently removed after a retention window (default 30 days; `SOFT_DELETE_RETENTION_DAYS`, `0` disables; settable per workspace at runtime via the `deletion-retention set-window` CLI, which takes precedence). The `deletion_retention.purge_soft_deleted` Celery beat task runs daily and removes each aged-out entity together with its M:N join rows, owned children, datasource permission, and version-history shadow rows. After purge an entity is **unrecoverable** — its detail and `/restore` endpoints return 404 and its version history is gone.
+
+The introducing release **defaults to dry-run** (`SOFT_DELETE_PURGE_DRY_RUN=True`): the task logs `would_purge` counts but deletes nothing, so operators can validate against production before activating real purging by setting it to `False`. Note `would_purge` is an **upper bound** — it counts every entity past the retention window without evaluating deletion blockers, so a real run may purge fewer (entities referenced by report schedules or set as a user's welcome dashboard are blocked and reported separately). The task only acts while the temporary `SOFT_DELETE` rollout flag is on.
+
+Deployments that replace the default `CELERY_CONFIG` must ensure workers register `superset.tasks.deletion_retention` and schedule the `deletion_retention.purge_soft_deleted` task themselves. The shipped Docker development config uses `imports` and includes both entries. While `SOFT_DELETE` is statically enabled, a missing beat entry logs a startup warning; when the override explicitly defines `imports`, a missing purge module is also reported.
+
+Operators can immediately erase a specific entity for compliance (GDPR) via `superset deletion-retention force-purge --uuid <uuid>`; this applies legacy hard-delete semantics — a live chart referencing a force-purged dataset is left without a datasource until re-pointed (the chart is not modified), and it purges the named entity even when it was never soft-deleted. Every purge writes an immutable, content-free audit record to the new `purge_audit_log` table that survives the entity it names: the **scheduled** purge fails closed (an entity whose audit row cannot be written is skipped and retried next run), while **force-purge** proceeds even if the audit write fails — the operator is present and deletion outranks audit for a compliance erasure.
+
+### Recently Archived view and permanent delete (purge) endpoints
+
+Behind the same `SOFT_DELETE` flag, a **Recently Archived** page (Settings menu, `/archived/`) lists soft-deleted charts, dashboards, and datasets with their archive time and archiving user, and offers **Recover** and **Delete permanently** row actions. The page admits any viewer holding `can_read` on **any** of the three types and offers each viewer only the types they can read; a viewer with none of the three sees an explanatory empty state, and unauthenticated requests are redirected to login.
+
+**New endpoints** — `POST /api/v1/{chart,dashboard,dataset}/<uuid>/purge` permanently delete a single **soft-deleted** row, running the same cascade as the retention task. Irreversible. Requires `can_write` on the entity plus editorship of the row (or admin), mirroring `/restore`. The endpoints answer 404 while `SOFT_DELETE` is off (restore deliberately stays live so rows archived before a flag-off remain recoverable), 404 for rows that are not soft-deleted, and 422 with a reason when the purge is blocked (an alert/report references the entity, a user has the dashboard as their welcome page, or a restrictive foreign key intervenes). A purge that cannot write its audit record is refused with 422 rather than executed unrecorded — unlike the operator CLI, an end user's purge never outranks the audit.
+
+With the flag on, delete confirmations across the chart/dashboard/dataset list pages change shape: a recoverable archive is confirmed with a primary **Archive** button and no type-DELETE friction, and the copy states the retention window when one is configured. A bulk dataset selection that includes semantic views keeps the full danger treatment, because semantic views have no soft-delete — they are deleted permanently and the confirmation says so.
+
+This also resolves the limitation noted under *Soft delete and restore for datasets*: a database blocked by soft-deleted datasets can now be freed by purging those datasets (per-entity endpoint, retention task, or `force-purge` CLI) instead of hard-deleting `tables` rows out-of-band.
+
+The `purge_audit_log` table is **never pruned by design** — the audit must survive the entities it names; operators who need to age it out should prune manually.

+Custom time ranges that use the "Now" or "Today" anchor (for the Start, End, or the relative anchor itself) previously resolved that anchor in UTC before formatting it into a naive datetime string, which was then re-parsed elsewhere as local time.

 If you accidentally used `yarn docusaurus docs:version` instead of `yarn version:add`:

 1. **Problem**: The version files were created but `versions-config.json` wasn't updated
 2. **Solution**: Either:
   - Revert the changes: `git restore user_docs_versions.json && rm -rf user_docs_versioned_docs/ user_docs_versioned_sidebars/`
   - Then use the correct command: `yarn version:add:user_docs <version>`

+
 - **Cross-section links**: Links between sections (e.g., from developer_docs to docs) need to be version-aware
 - **Absolute vs relative paths**: Use relative paths within the same section
 - **Version-specific URLs**: Update hardcoded URLs to use version variables

+## Chart-data query timing
+
+Set `CHART_DATA_INCLUDE_TIMING = True` to add an optional versioned timing object
+to every successful JSON query result returned by the chart-data API. The setting
+is `False` by default, so enabling it is an explicit API-contract choice for an
+operator. File exports, streaming responses, and HTTP error responses do not
+include this object.
+
+```json
+{
+  "timing": {
+    "version": 1,
+    "query": {
+      "query_planning_ms": 1.23,
+      "cache_resolution_ms": 0.45,
+      "data_acquisition_ms": null,
+      "payload_assembly_ms": 0.67,
+      "total_ms": 2.98
+    }
+  }
+}
+```
+
+Durations are milliseconds rounded to two decimal places. A numeric `0.0`
+means that the corresponding stage ran but rounded below that precision;
+`null` means it did not apply. For example, `data_acquisition_ms` is null for
+a normal dataframe cache hit, while metadata-only results have null phase values
+and a numeric total.
+
+The phases have fixed ownership: `query_planning_ms` includes Jinja rendering,
+row-level-security transformation, and cache identity; `cache_resolution_ms`
+includes cache lookup, compatibility policy, deserialization, and rehydration;
+`data_acquisition_ms` includes database work and annotation dependencies; and
+`payload_assembly_ms` includes response shaping and AUTO-currency fallback.
+
+`total_ms` is measured over one continuous per-query execution interval. It
+contains the exposed stages and unattributed work such as query-result cache
+persistence, so it is not the sum of the phase values. Query-context cache
+persistence is excluded. The total also excludes request parsing,
+authorization, contribution-total work before the per-query loop, client
+post-processing, JSON serialization, network transfer, and background async
+producer execution. Additive optional fields can preserve version 1; a field
+rename, removal, or semantic change requires a new version.

+### Adding translations to a custom image
+
+The pattern above, a small Dockerfile that just extends `FROM apache/superset:...`, can't add
+translations after the fact. By the time an official tag is published, its frontend and backend
+layers have already had non-English translation files stripped out unless `BUILD_TRANSLATIONS`
+was set at build time (see below), and there's no `superset/translations` source tree left in the
+final image to compile from.
+
+To get translations into your own image, you need to build from the full Superset source (a
+clone or fork of this repo) rather than extend a published tag. The most efficient way to do this
+is to append your customizations as one more stage at the end of the repo's own `Dockerfile`, so
+Docker can reuse the cached upstream layers and only rebuild what your stage adds:
+
+```Dockerfile
+# Append this to the end of the repo's Dockerfile
+# Keep this tag in sync with the branch/tag of the repo you cloned, so the
+# translation files built from source match the keys the runtime expects:
+FROM apache/superset:5.0.0 AS my-custom-image
+USER root
+
+# Pull the translation files out of the earlier build stages (frontend
+# .json in `superset-node`, backend .mo in `python-translation-compiler`).
+# Those stages' own cleanup only matches single-character extensions, so
+# the source `.po` files can still be present here; strip them explicitly
+# so this stage only keeps the compiled translations.
+COPY --from=superset-node /app/superset/translations superset/translations
+COPY --from=python-translation-compiler /app/translations_mo superset/translations
+RUN find superset/translations -name '*.po' -delete
+
+USER superset
+```
+
+Then build with:
+
+```bash
+docker build --target=my-custom-image --build-arg=BUILD_TRANSLATIONS=true -t mysuperset:5.0.0 .
+```
+
+You can combine this with the database-driver/dependency pattern above by adding your own
+`RUN uv pip install ...` step before switching back to `USER superset`. See
+[issue #35959](https://github.com/apache/superset/issues/35959) for the discussion this pattern
+came out of, credit to the community for working it out.
+
 ## Key ARGs in Dockerfile

- `BUILD_TRANSLATIONS`: whether to build the translations into the image. For the
-  frontend build this tells webpack to strip out all locales other than `en` from
-  the `moment-timezone` library. For the backendthis skips compiling the
-  `*.po` translation files
+- `BUILD_TRANSLATIONS`: whether to compile non-English translations into the image.
+  When `true`, the frontend build converts the `*.po` files to locale JSON and the
+  backend runs `pybabel compile` to produce `*.mo` files; both source `*.po` files
+  are stripped afterward either way. When `false` (the default), those compile
+  steps are skipped and only `en` ships. This only takes effect when building the image from source
+  (`docker build` against this repo's own `Dockerfile`); it has no effect on a downstream
+  Dockerfile that just extends an already-published tag, see
+  "Adding translations to a custom image" above. Note that the backend `pybabel compile`
+  step ignores its exit code, so a `.po` file with a compile error won't fail the build;
+  check the build logs for `pybabel` warnings if a locale's backend strings aren't showing up.
 - `DEV_MODE`: whether to skip the frontend build, this is used by our `docker-compose` dev setup
  where we mount the local volume and build using `webpack` in `--watch` mode, meaning as you
  alter the code in the local file system, webpack, from within a docker image used for this

 The default Apache Superset configuration is optimized for ease of use and development, not for security. For any production deployment, it is **critical** that you review and apply the following security configurations to harden your instance, protect user data, and prevent unauthorized access.

 Running Superset without HTTPS (TLS) is not secure. Without it, all network traffic—including user credentials, session tokens, and sensitive data—is sent in cleartext and can be easily intercepted.

-* **Use a Reverse Proxy:** Your Superset instance should always be deployed behind a reverse proxy (e.g., Nginx, Traefik) or a load balancer (e.g., AWS ALB, Google Cloud Load Balancer) that is configured to handle HTTPS termination.
-* **Enforce Modern TLS:** Configure your proxy to enforce TLS 1.2 or higher with strong, industry-standard cipher suites.
-* **Implement HSTS:** Use the HTTP Strict Transport Security (HSTS) header to ensure browsers only connect to your Superset instance over HTTPS. This can be configured in your reverse proxy or within Superset's Talisman settings.

 ### **`SUPERSET_SECRET_KEY` Management (CRITICAL)**

 This is the most critical security setting for your Superset instance. It is used to sign all session cookies and encrypt sensitive information in the metadata database, such as database connection credentials.

-* **Generate a Unique, Strong Key:** A unique key must be generated for every Superset instance. Use a cryptographically secure method to create it.
-    ```bash
-    # Example using openssl to generate a strong key
-    openssl rand -base64 42
-    ```
-* **Store the Key Securely:** The key must be kept confidential. The recommended approach is to store it as an environment variable or in a secrets management system (e.g., AWS Secrets Manager, HashiCorp Vault). **Do not hardcode the key in `superset_config.py` or commit it to version control.**
-    ```python
-    # In superset_config.py
-    import os
-    SECRET_KEY = os.environ.get('SUPERSET_SECRET_KEY')

-  * **Principle of Least Privilege:** Assign users to the most restrictive roles necessary for their jobs. Avoid over-provisioning users with Admin or Alpha roles, and ensure row-level security is applied where appropriate.

 > It is essential to understand that **Apache Superset is a data visualization and exploration platform, not a database firewall or a comprehensive security solution for your data warehouse.** While Superset provides features to help manage data access, the ultimate responsibility for securing your underlying databases lies with your database administrators (DBAs) and security teams. This includes managing network access, user privileges, and fine-grained permissions directly within the database. The configurations below are an important secondary layer of security but should not be your only line of defense.

-  * **Use a Dedicated Database User:** The database connection configured in Superset should use a dedicated, limited-privilege database user. This user should only have the minimum required permissions (e.g., `SELECT` on specific schemas) for the data sources it needs to query. It should **not** have `INSERT`, `UPDATE`, `DELETE`, or administrative privileges.
-  * **Restrict Dangerous SQL Functions:** To mitigate potential SQL injection risks, configure the `DISALLOWED_SQL_FUNCTIONS` list in your `superset_config.py`. Be aware that this is a defense-in-depth measure, not a substitute for proper database permissions.

-      * Changes to user roles or permissions.
-      * Creation or deletion of high-privilege users.
-      * Attempts to use disallowed SQL functions.

 - The dashboard must still be published to be visible

 This feature is particularly useful for:
+
 - Making specific dashboards public while keeping others private
 - Granting access to dashboards without exposing the underlying datasets for other uses
 - Creating dashboard-specific access patterns that don't align with dataset permissions

+#### Assigning the creator's groups automatically
+
+```python
+FEATURE_FLAGS = {
+    "ENABLE_VIEWERS": True,
+    "ASSIGN_CREATOR_GROUPS_AS_VIEWERS": True,
+}
+```
+
+This requires `ENABLE_VIEWERS` — it has no effect on its own, since it works by populating the
+`viewers` relationship that `ENABLE_VIEWERS` governs.
+
+With this enabled, a newly created dashboard or chart is shared read-only with every group its
+creator belongs to, unless the create payload names viewers explicitly. It applies to every path
+that creates an asset: the REST API, `/dashboard/new/`, save-as from Explore, dashboard copy,
+the import commands, and the MCP tools. Datasets are unaffected, as they have editors but no
+viewers.
+
+For dashboards, viewer access additionally requires the dashboard to be **published** — the same
+rule that governs every dashboard viewer. Until a new dashboard is published its creator's groups
+see nothing, and because it now has viewers the dataset-based fallback no longer applies to it
+either; group members gain access only once it is published. Charts have no such publish gate, so a
+new chart's viewer grant takes effect immediately. Note, though, that the viewer relationship
+governs access to the chart itself; rendering its **data** still runs the normal datasource
+permission check unless `VIEWER_PROMISCUOUS_MODE` is enabled — a group member without access to the
+underlying dataset can open the chart but won't load its data.
+
+Note that this **narrows** access rather than widening it. Because an asset with no viewers falls
+back to dataset-based access, giving new assets a viewer makes that fallback unreachable for them:
+a colleague who could previously open a new dashboard by virtue of dataset access can no longer do
+so unless they share one of the creator's groups. Existing assets are untouched — only assets
+created after the feature flag is enabled are affected.
+
+The same narrowing affects background execution as a fixed identity. Alerts, reports, and
+thumbnails that run as a `FixedExecutor` service account (via `ALERT_REPORTS_EXECUTE_AS` or
+`THUMBNAIL_EXECUTE_AS`) reach a chart or dashboard through the dataset fallback when that account
+is neither an editor nor a viewer. Once a new asset is scoped to the creator's groups that
+fallback is gone, so rendering fails `raise_for_access` unless the executor account is an admin,
+an editor, or shares one of those groups. If a fixed executor must render assets it does not own,
+grant it the needed access (make it an admin or add it to the relevant groups) — or leave the
+feature flag off.
+
+The setting assigns groups as *viewers*, not editors, so group members get read-only access and
+cannot modify or delete the asset.

 ### SQL Execution Security Considerations

 Apache Superset includes features designed to provide safeguards when interacting with connected databases, such as the `DISALLOWED_SQL_FUNCTIONS` configuration setting. This aims to prevent the execution of potentially harmful database functions or system variables directly from Superset interfaces like SQL Lab.
@@ -260,10 +308,11 @@ However, it is crucial to understand the following:
 **Database Security is Paramount**: The ultimate responsibility for securing database access, controlling permissions, and preventing unauthorized function execution lies with the database administrators (DBAs) and security teams managing the underlying database instance.

 **Recommended Database Practices**: We strongly recommend implementing security best practices at the database level, including:
-* **Least Privilege**: Connecting Superset using dedicated database user accounts with the minimum permissions required for Superset's operation (typically read-only access to necessary schemas/tables).
-* **Database Roles & Permissions**: Utilizing database-native roles and permissions to restrict access to sensitive functions, system variables (like `@@hostname`), schemas, or tables.
-* **Network Security**: Employing network-level controls like database firewalls or proxies to restrict connections.
-* **Auditing**: Enabling database-level auditing to monitor executed queries and access patterns.
