experiment: test model_class= fix for FSA 3.x break (DO NOT MERGE)

Investigation-only commit for discussion #40273 / PR #42542's revert. Passes model_class=flask_appbuilder.models.sqla.Model explicitly when constructing SQLA() in superset/extensions/__init__.py, testing the theory that FAB's FSA-3.x shim (base.py) leaves Superset's models and db.session looking at two disconnected declarative registries, since unlike the FSA-2.x shim (base_legacy.py) it never wires model_class through. Local pytest runs against sqlite reproduce neither the break nor a fix signal (matches PR #42542's original finding that this only surfaced under real CI). This commit exists to get a real CI signal on test-sqlite/test-mysql before deciding whether to pursue this as an actual fix (and whether it needs an upstream flask-appbuilder change too, or is fixable entirely on Superset's side as this attempts).
fix(reports): use zip extension for bundled CSV attachments (#42640 )

+# 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.

 ## Next

+### 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).
+
+### Dashboard "Export Data to Excel" requires a Celery worker and S3 bucket
+
+A new dashboard action exports every chart's data to a single multi-sheet
+`.xlsx` asynchronously. It is disabled by default and turns on only when
+`EXCEL_EXPORT_S3_BUCKET` is set (the endpoint returns `501` otherwise). It also
+requires a running Celery worker and a configured SMTP transport, since the task
+emails the requesting user a pre-signed download link. New config keys:
+`EXCEL_EXPORT_S3_BUCKET`, `EXCEL_EXPORT_S3_KEY_PREFIX`,
+`EXCEL_EXPORT_LINK_TTL_SECONDS`, `EXCEL_EXPORT_S3_CLIENT_KWARGS`, and
+`EXCEL_EXPORT_TABLE_VIZ_TYPES`.
+
+The feature depends on `boto3`, which is **not** installed by default; install it
+with `pip install apache-superset[excel-export]`.
+
+A second mode, **Export Images to Excel**, embeds non-table charts as rendered
+images (which viz types stay tabular is controlled by
+`EXCEL_EXPORT_TABLE_VIZ_TYPES`). It renders through the headless webdriver, so the
+menu option only appears when the webdriver screenshot feature flags
+(`ENABLE_DASHBOARD_SCREENSHOT_ENDPOINTS`,
+`ENABLE_DASHBOARD_DOWNLOAD_WEBDRIVER_SCREENSHOT`) are enabled.
+
+Deployments that override `CELERY_CONFIG` must add
+`"superset.tasks.export_dashboard_excel"` to their `imports` tuple, or the task
+will not register and exports will silently never run.
+
+### SQL_QUERY_MUTATOR now honors MUTATE_AFTER_SPLIT in SQL Lab
+
+SQL Lab now applies `SQL_QUERY_MUTATOR` according to `MUTATE_AFTER_SPLIT`, matching the documented semantics and the chart/query path. This only affects deployments that define `SQL_QUERY_MUTATOR` in `superset_config.py`:
+
+- With `MUTATE_AFTER_SPLIT = True`, the mutator previously never ran in SQL Lab; it now runs on each individual statement (including on engines like BigQuery and Kusto that execute multiple statements as one block, where each statement is mutated before the statements are joined).
+- With `MUTATE_AFTER_SPLIT = False` (the default), multi-statement SQL Lab queries previously applied the mutator to each statement separately; the mutator now runs once on the whole un-split query, as documented. Single-statement queries are unaffected.
+- With `MUTATE_AFTER_SPLIT = False` on engines that execute statements individually, the mutator's output is re-parsed to split it into statements. A mutator that emits SQL Superset's parser cannot parse will now fail with a clear parse error before execution, and one that strips a query down to nothing raises an invalid-SQL error instead of executing an empty query.
+
+### Python 3.10 support removed
+
+Python 3.10 is no longer supported. Superset now requires **Python 3.11 or higher**.
+Update your environment (virtualenv, Docker base image, CI configuration, etc.) to
+Python 3.11+ before upgrading. The `apache/superset-cache:3.10-slim-trixie` and
+`py310` Docker image variants are no longer published.
+
+### `from_dttm` and `to_dttm` Jinja template variables removed
+
+The `{{ from_dttm }}` and `{{ to_dttm }}` Jinja template variables, deprecated since
+v5.0, have been removed from the Jinja context and are no longer available in virtual
+dataset SQL or custom SQL expressions.
+
+Replace usages with the `get_time_filter()` function. For example:
+
+```sql
+-- Before
+SELECT * FROM tbl
+WHERE dttm_col > '{{ from_dttm }}' AND dttm_col < '{{ to_dttm }}'
+
+-- After
+{% set tf = get_time_filter("dttm_col") %}
+SELECT * FROM tbl
+WHERE dttm_col > {{ tf.from_expr }} AND dttm_col <= {{ tf.to_expr }}
+```
+
+Note that `from_expr` and `to_expr` are already fully-formatted SQL expressions (e.g.
+`TO_TIMESTAMP('2024-01-01', ...)`) — do not wrap them in single quotes.
+
+### Removed deck.gl JavaScript tooltip/data-mutator controls and ENABLE_JAVASCRIPT_CONTROLS
+
+The `ENABLE_JAVASCRIPT_CONTROLS` feature flag and the deck.gl chart controls it gated
+(`js_tooltip`, `js_onclick_href`, `js_data_mutator`, and the GeoJSON layer's label/icon
+JavaScript-mode generators) have been removed. These controls let users write arbitrary
+JavaScript, sandboxed via Node's `vm` module, to customize deck.gl tooltips, click
+behavior, and data transforms; the flag defaulted off and the feature saw negligible use.
+
+The deck.gl "Extra data for JS" control (`js_columns`) has also been removed. It only
+ever existed to feed extra columns into the JavaScript controls above; deck.gl's
+built-in field-based tooltips and cross-filtering already pull in any columns they need
+via `tooltip_contents`/`cross_filter_column`, so this control had no remaining purpose.
+Any chart layer whose "Advanced" control panel section only contained this control no
+longer has an "Advanced" section.
+
+Any saved charts with these fields set will simply ignore them going forward and fall back
+to deck.gl's built-in field-based tooltips (`tooltip_contents`/`tooltip_template`) and
+native click/cross-filter behavior. No migration is required; the fields are dropped
+silently on next save.

The no-timeout default can now be overridden via two new config keys, `CACHE_REDIS_SOCKET_TIMEOUT` / `CACHE_REDIS_SOCKET_CONNECT_TIMEOUT`, on any `CacheConfig` dict using `CACHE_TYPE: RedisCache` or `RedisSentinelCache`. Separately, redis-py 6+ changed the default for `ssl_check_hostname` from `False` to `True` for SSL connections using `ssl_cert_reqs="required"` (the default) — this is a security improvement, so it has **not** been reverted; deployments with `CACHE_REDIS_SSL=True` whose certificates lack a hostname matching the connection address should set `CACHE_REDIS_SSL_CERT_REQS="none"` (disables cert verification entirely, matching hostname-check bypass) or replace the certificate. General-purpose cache/results backends configured via `CACHE_CONFIG` / `DATA_CACHE_CONFIG` / `RESULTS_BACKEND` with `CACHE_TYPE: RedisCache` go through `flask-caching`'s own Redis backend (outside Superset's code) and are subject to the same new defaults; pass `socket_timeout` / `protocol` via `CACHE_OPTIONS` there if needed. Celery broker and result-backend connections (built by `kombu`, also outside Superset's code) keep their no-socket-timeout behavior (`kombu` passes `socket_timeout=None` explicitly) but do **not** pin the wire protocol, so they follow redis-py's RESP3 default — which requires a Redis server new enough to speak `HELLO` (Redis 6+). Deployments using a pre-6.0 Redis server (EOL) as a Celery broker should upgrade the server before taking this bump.

 - [39925](https://github.com/apache/superset/pull/39925): URL prefixing for `SUPERSET_APP_ROOT` subdirectory deployments is now handled automatically by helpers in `src/utils/navigationUtils` (`openInNewTab`, `redirect`, `getShareableUrl`, `<AppLink>`). Direct imports of `ensureAppRoot` / `makeUrl` from `src/utils/pathUtils` are forbidden outside `navigationUtils.ts` (enforced by a static-invariant test); contributors writing new code should use the focused helpers instead. No runtime behaviour change for existing callers — all 19 prior call sites have been migrated and four pre-existing double-prefix and missing-prefix bugs are fixed as part of the migration.

 - [39925](https://github.com/apache/superset/pull/39925): `SupersetClient.getUrl()` now strips a single leading application-root segment from the supplied `endpoint` before building the request URL, so a caller that accidentally pre-prefixes its endpoint (for example by wrapping it with `ensureAppRoot` before passing it to the client) no longer produces a doubled `/superset/superset/...` URL under subdirectory deployment. The strip is **single-pass** — a genuine `/superset/superset/<slug>` route is preserved, not collapsed — and **silent** (no console warning); the static-invariant test remains the primary signal for pre-prefixing at the call site, and this runtime strip is a safety net beneath it. Code that intentionally targeted a literal `/<app_root>/<app_root>/...` endpoint through `getUrl` (a configuration that has no legitimate use under the prefixing model) would have its first redundant segment removed.

 ### Guest-token RLS rules reject unknown fields

 The `rls` rules passed to `POST /api/v1/security/guest_token/` are now validated strictly: a rule may only contain `dataset` and `clause`. Previously unknown fields were silently dropped, so a mistyped or legacy scope key (most commonly `datasource` instead of `dataset`) produced a rule with no `dataset`, which is treated as a *global* rule applied to every dataset the embedded resource can reach. Such a request now returns HTTP 400 identifying the offending field instead of issuing a token with an unintended global rule. Integrators that were sending extra fields in RLS rules must remove them; valid dataset-scoped (`{"dataset": 41, "clause": "..."}`) and global (`{"clause": "..."}`) rules are unaffected.

Tooltips read grain-appropriate labels such as `Jan 2021` (month), `2021 Q1` (quarter), `2021` (year), and weekly date ranges, becoming grain-aware like the x-axis, though the two are formatted independently and their labels may not always match exactly. Only a custom, explicitly-set tooltip time format (a d3 format string) is unaffected — that always wins over the grain.

 ### Pivot table First/Last aggregations follow data order

 The pivot table chart's `First` and `Last` aggregations now return the first and last value in data (query result) order, instead of effectively returning the minimum and maximum. Existing pivot tables that use these aggregations for totals/subtotals may show different values after upgrading. For deterministic results, ensure the underlying query has a stable sort order.

Widen your callback signatures to accept `Error | null` / `Response | null`.

+### Pivot Table totals are now computed by the database (per-metric "Aggregation function" control removed)
+
+Pivot Table subtotals and grand totals are now computed by the database at each
+rollup level instead of re-aggregating the already-aggregated cell values on the
+client. This fixes long-standing incorrect totals for non-additive metrics
+(ratios such as `SUM(a)/SUM(b)`, `COUNT_DISTINCT`, `AVG`, percentiles, etc.),
+which previously summed the displayed cell values.
+
+As a result the per-table **"Aggregation function"** control (which let you pick
+how totals were aggregated client-side, e.g. Sum/Average/Count) has been
+removed: totals now always reflect the metric's own definition evaluated at the
+total's granularity. For additive metrics (`SUM`/`COUNT`/`MIN`/`MAX`) the result
+is unchanged. Saved charts that set `aggregateFunction` will ignore it; no
+migration is required. If you previously relied on a plain sum-of-cells total
+for a non-additive metric, that specific behavior is no longer available.

+### Dashboard import can overwrite related charts, datasets, and databases
+
+Re-importing an existing dashboard previously overwrote only the dashboard itself; its related charts, datasets, and databases were never updated (the importer hardcoded `overwrite=False` for them). They can now be overwritten as part of the import.
+
+A new `overwrite_all` form field controls this, and defaults to `false` everywhere, so existing behavior is preserved: passing `overwrite=true` alone still overwrites only the dashboard, exactly as before. To also overwrite the related charts, datasets, and databases on the `/api/v1/dashboard/import/` endpoint, pass `overwrite_all=true` explicitly. The import modal in the UI exposes this as an "also overwrite all assets" checkbox, and the CLI `superset import-dashboards` and the `ImportDashboardsCommand` likewise default `overwrite_all` to `false`.

+### Cross-entity version activity stream
+
+A read-only companion to the version-history endpoints: each entity type gains a `GET /api/v1/{chart,dashboard,dataset}/<uuid>/activity/` endpoint returning a chronological, access-filtered stream of edits — the entity's own edits plus, for charts and dashboards, transitive edits to related entities during their association windows. Datasets have no related layer in V2, so `include=related` returns an empty stream for a dataset and `include=all` reduces to the dataset's own edits.
+
+| Param | Type | Default | Purpose |
+|---|---|---|---|
+| `since` / `until` | ISO 8601 | — | Bound `issued_at` |
+| `include` | `self` \| `related` \| `all` | `all` | Own edits, related edits, or both |
+| `q` | string | — | Case-insensitive search over the full history, applied before pagination (so `count` reflects matches) |
+| `page` / `page_size` | integer | `0` / `25` | Pagination (`page_size` clamped to 200) |
+
+Authorization reuses the resource's `can_read` permission and per-object `raise_for_access`; related-entity rows are visibility-filtered to what the caller may see. The stream is empty unless version capture is on (`ENABLE_VERSIONING_CAPTURE`).
+
+### Version-history retention (pruning)
+
+Entity version history (the `version_transaction` / `*_version` shadow tables that back version capture) is aged out by a nightly Celery beat task, `version_history.prune_old_versions` (`superset.tasks.version_history_retention`).
+
+| Key | Default | Purpose |
+|---|---|---|
+| `SUPERSET_VERSION_HISTORY_RETENTION_DAYS` | `30` | Version rows whose owning `version_transaction.issued_at` is older than this many days are pruned. Each entity's live row (`end_transaction_id IS NULL`) is always preserved, as are the live rows of its children and associations; closed historical rows (including the baseline) age out. Set to `0` or a negative value to disable pruning. |
+
+The task ships in the default `CeleryConfig.beat_schedule`; a deployment that overrides `CELERY_CONFIG` without inheriting the default will log a startup warning that the prune task is absent (so it never silently stops running). 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 add `superset.tasks.deletion_retention` to the Celery `imports` and schedule the `deletion_retention.purge_soft_deleted` task themselves. The shipped Docker development config includes both entries.
+
+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.

 **Importer behavior:** importing a dashboard YAML whose UUID matches an existing **soft-deleted** dashboard is treated as an implicit restore-with-update — **and this happens even when `overwrite` is not set**. This is a deliberate asymmetry with active rows: an active dashboard imported without `overwrite=true` is returned unchanged (the import never mutates it), but a soft-deleted UUID match is restored *and* has the upload's contents applied regardless of the `overwrite` argument, on the reasoning that re-importing a deleted dashboard's exact UUID is an explicit request to bring it back. The restore preserves the original PK and all pre-deletion relationship rows (`dashboard_slices` junctions, editor/viewer subjects, tags). Callers whose imports must never mutate existing state should treat bundles that may contain previously deleted UUIDs accordingly. The operation is permission-gated: it requires `can_write` and editorship of the deleted row (or admin) — non-editors get `ImportFailedError`, and callers without `can_write` get `ImportFailedError` instead of silently receiving the soft-deleted row.

+### Engine spec capability flag: `supports_offset`
+
+A new `BaseEngineSpec.supports_offset` attribute (default `True`) indicates whether a database engine supports the SQL `OFFSET` clause. Engines that do not support `OFFSET` — such as Elasticsearch SQL and OpenDistro — opt out by setting it to `False`, and Superset uses each engine's cursor API to paginate drill-to-detail samples instead of emitting `OFFSET`. Downstream forks maintaining custom engine specs may set the flag to `False` (and implement `fetch_data_with_cursor`) to avoid crashes when paginated drill-to-detail queries are run against engines without `OFFSET` support.
+
+**Note on deep-pagination cost:** Cursor-based engines (including Elasticsearch and OpenDistro) are forward-only, so reaching page `N` of a drill-to-detail view issues `N` round trips to the cluster. Deep pagination is therefore linear in page number; users paginating into the hundreds or thousands will notice added latency compared to `OFFSET`-capable engines.

+### Custom time range "Now"/"Today" anchors resolve in local time
+
+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. For users outside UTC, this made the resolved anchor drift by their browser's UTC offset. "Now"/"Today" now resolve directly in local time, matching the later local re-parse.

   - Then use the correct command: `yarn version:add:user_docs <version>`

 - **Absolute vs relative paths**: Use relative paths within the same section
 - **Version-specific URLs**: Update hardcoded URLs to use version variables

+The worker may be unable to reach the report. It will use the value of `WEBDRIVER_BASEURL` to browse to the report. If that route is invalid, or presents an authentication challenge that the worker can't pass, the report screenshot will fail.

 Check this by attempting to `curl` the URL of a report that you see in the error logs of your worker. For instance, from the worker environment, run `curl http://superset_app:8088/superset/dashboard/1/`. You may get different responses depending on whether the dashboard exists - for example, you may need to change the `1` in that URL. If there's a URL in your logs from a failed report screenshot, that's a good place to start. The goal is to determine a valid value for `WEBDRIVER_BASEURL` and determine if an issue like HTTPS or authentication is redirecting your worker.

+
+Very large chart or SQL query results can flood the cache backend (Redis/Memcached), evicting many

+## 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
