Merge origin/master into misc-charts-examples

Life Expectancy Histogram had the same bug as the earlier Bubble chart
fix: its adhoc filter pointed at 2014, which has zero SP_DYN_LE00_IN data
in the world_health dataset, so the thumbnail showed an empty chart.
Moved it to 2011, which has real data.

Deck.gl GeoJson rendered as a single solid-colored blob: the global
fill_color_picker (alpha=1) always overrides any per-feature fill color,
and line_width defaulted to ~1 meter, invisible at city zoom, so none of
the 25 zip-code boundaries were visible. Baked a population-ranked
choropleth fill-color into each zip code's GeoJSON Feature, set
fill_color_picker's alpha to 0 so the per-feature colors show through,
switched the stroke to a visible white pixel-width line, and turned off
the extruded flag since there's no per-feature elevation data backing it.

+### OAuth2 database callback metrics include their outcome
+
+The unqualified `DatabaseRestApi.oauth2` StatsD counter has been replaced with
+`DatabaseRestApi.oauth2.success`, `DatabaseRestApi.oauth2.warning`, and
+`DatabaseRestApi.oauth2.error`. Update monitoring rules and dashboards that consume
+the old counter to use the outcome-specific replacements.
+
+- [42935](https://github.com/apache/superset/pull/42935): The MCP service now refuses to start (`MCPAuthConfigError`) when `MCP_JWT_ISSUER` trusts more than one issuer and no `MCP_USER_RESOLVER` is configured, instead of only logging a warning. This was already a documented misconfiguration (the default resolver isn't issuer-scoped, so distinct trusted issuers minting the same username/email would resolve to the same Superset user); deployments trusting multiple issuers must configure an `MCP_USER_RESOLVER` that derives its identity from the token's `iss` claim before upgrading. Single-issuer deployments are unaffected.
 - [42393](https://github.com/apache/superset/pull/42393): Exported dataset YAML now carries a `uuid` for each metric and column so that custom folder assignments (which reference metrics/columns by UUID) survive an import into another workspace. This affects any export bundle that contains datasets, not just a dataset export: chart, dashboard, database and full-asset exports all embed the same dataset YAML, so a dashboard exported from this release also fails to import into an older one even though no dataset was exported directly. As with `folders` and `currency_code_column`, the affected `datasets/` files fail schema validation (`Unknown field: uuid`) when imported into Superset releases that predate this change; regenerate or hand-edit exports for older targets in mixed-version fleets.
+- [42300](https://github.com/apache/superset/pull/42300): Timeseries charts (line/area/bar) with a Y-axis bound in effect — either an explicit `yAxisBounds` or one derived from `truncateYAxis` — now clamp out-of-range data points to that bound instead of letting ECharts drop the point (and the line segments around it) entirely. Any existing chart with a configured Y-axis bound and data outside it will look different after upgrading: a gap becomes a point pinned to the boundary. The clamp also rewrites the value ECharts reads for that point's tooltip and data label, so the displayed value is the bound rather than the true observation.
+- [42087](https://github.com/apache/superset/pull/42087): Stored calculated-column and metric expressions are validated when a query is built, under the same sub-query policy already applied to adhoc expressions. Previously only the dataset update path checked them on save, so expressions written by v1 import, by dataset duplication, or before that check existed were never validated. Since `ALLOW_ADHOC_SUBQUERY` defaults to `False` (see [19242](https://github.com/apache/superset/pull/19242)), a dataset whose stored expression contains a sub-query works before upgrading and afterwards fails at chart render with `Custom SQL fields cannot contain sub-queries.` There is no migration step, and the error does not name the offending dataset column, so audit stored expressions before upgrading: either rewrite them without the sub-query, or set `ALLOW_ADHOC_SUBQUERY = True` to keep the previous behaviour for both stored and adhoc expressions.

+
+Selenium support has been removed. **Playwright is now required** for all
+report and thumbnail screenshot generation. Install it with:
+
+```bash
+pip install playwright && playwright install chromium
+```
+
+**Breaking config changes:**
+
+- `PLAYWRIGHT_REPORTS_AND_THUMBNAILS` feature flag removed (Playwright is the only backend now)
+- `WEBDRIVER_TYPE` config key removed (Playwright always uses Chromium)
+- `WEBDRIVER_CONFIGURATION` config key removed (Selenium-only)

+
+**What operators should do before upgrading:**
+
+1. Install Playwright: `pip install playwright && playwright install chromium`

+3. If you subclassed `MachineAuthProvider`, remove any `authenticate_webdriver` override and migrate auth logic to `authenticate_browser_context`
+
+### CSV/XLSX report exports of Table charts keep raw numeric values
+
+Table and Pivot Table charts sent as text in a report email now apply the
+chart's number and currency formatting so the values match what a user sees in
+Explore. As part of this, the CSV and XLSX result formats return early before
+formatting: previously the Table post-processor applied `d3NumberFormat` to
+every result format, so CSV/XLSX exports contained pre-formatted strings.
+CSV/XLSX exports now preserve numeric values and column types, which is better
+for downstream analysis but is a visible change for anyone who relied on the
+formatted text in those files. The rendered email body (the only place the
+formatting is intended for) is unaffected.
+
+### SQLAlchemy bumped to 2.0, flask-sqlalchemy to 3.1.1
+
+Superset's core ORM dependencies move from SQLAlchemy 1.4 to 2.0 and
+flask-sqlalchemy `<3.0` to 3.1.1, completing the migration tracked in
+[discussion #40273](https://github.com/apache/superset/discussions/40273).
+
+**Custom `db_engine_specs`, plugins, or extensions that import SQLAlchemy
+internals directly** should review the
+[SQLAlchemy 1.4-to-2.0 migration guide](https://docs.sqlalchemy.org/en/20/changelog/migration_20.html)
+for API changes that affect them — most 1.4 code already runs unmodified
+under 2.0's compatibility mode, but patterns like `Engine.execute()`,
+string-keyed `Row` access, and `MetaData(bind=)` are removed outright.
+
+**Several optional DB-connector extras remain capped below their
+SQLAlchemy-2.0-only releases**, either because that bump is a separate
+follow-up ([#42891](https://github.com/apache/superset/pull/42891): dremio,
+exasol, firebird, redshift, risingwave) or because the upstream dialect
+package has no SQLAlchemy 2.0 support yet at all (aurora-data-api, d1,
+kusto, solr; ocient's 2.0 compatibility is unverified). Installing one of
+these extras continues to pull a SQLAlchemy-1.4-line version of that
+dialect; each package's constraint in `pyproject.toml` documents why.
+
+No application-level configuration changes are required for deployments
+that don't touch SQLAlchemy directly.

+API responses served to a guest-token principal now carry a generic
+`An error occurred while fetching the data.` in place of the underlying error
+(`You don't have permission to access this resource.` on a 401/403), and drop
+the `stacktrace` and error `extra` payloads. Engine errors routinely quote

+
+### `UnsavedChangesModal` no longer accepts a `zIndex` prop
+
+`@superset-ui/core`'s `UnsavedChangesModal` dropped its `zIndex` prop (and the
+hardcoded default it fed) in favor of letting Ant Design's own stacking
+handle placement. Callers passing `zIndex` to override the modal's layering
+will now get a TypeScript error and must remove the prop; keeping a manual
+override was exactly the footgun this change removes (see #42510). No
+callers in the Superset frontend codebase itself passed this prop.
+
+### Row-level security now filters table reads a same-named CTE used to hide
+
+`extract_tables_from_statement()` decided whether a reference was a CTE by matching its
+bare name against the enclosing scope's CTE names; it now resolves the name through
+`Scope.cte_sources`. Three kinds of real table read whose bare name collided with a CTE's
+were mistaken for the CTE and dropped from a statement's tables, so they were neither
+RLS-filtered nor access-checked: a schema- or catalog-qualified reference, a non-recursive
+CTE's own name inside its body, and a forward reference to a later `WITH` item.
+
+```sql
+WITH orders AS (SELECT 1 AS d) SELECT * FROM (SELECT * FROM public.orders) AS z
+WITH orders AS (SELECT * FROM orders) SELECT * FROM orders
+WITH q1 AS (SELECT key FROM q2), q2 AS (SELECT 1 AS key) SELECT * FROM q1
+```
+
+Each read is now reported, so it is filtered when `RLS_IN_SQLLAB` is enabled, matched
+against `DISALLOWED_SQL_TABLES`, and requires dataset access under
+`raise_for_access(force_dataset_match=True)`. A query that previously ran, reading those
+rows unfiltered, may now be filtered or rejected. There is no opt-out — the previous
+behavior was a row-level-security bypass.
+
+### Table aliases keep their quoting through the row-level security rewrite
+
+Both RLS transformers took the table alias as a string with its quoting stripped and
+emitted it verbatim; they now carry the parsed identifier. Emitted SQL is unchanged for an
+unquoted identifier; a quoted one keeps its quoting, and a column-alias list
+(`FROM t AS x (c1, c2)`) survives the rewrite instead of being dropped. This repairs
+row-level security for any aliased table on Snowflake, and for at least one statement shape

+#### Slack delivery timeouts and retries
+
+Slack delivery uses a request timeout and an application retry budget:
+
+```python
+# Timeout for one Slack API request, in seconds
+SLACK_API_TIMEOUT = 30
+
+# Retry budget shared by every Slack destination and upload phase
+SLACK_SEND_RETRY_MAX_TIME = 150
+

+SLACK_API_RATE_LIMIT_RETRY_COUNT = 2
+
+# Cooldown after an on-demand channel-cache refresh
+SLACK_CHANNEL_REFRESH_COOLDOWN_SECONDS = 300
+```
+
+All channels and upload phases in one report execution share a single
+`SLACK_SEND_RETRY_MAX_TIME` budget. This prevents a large recipient list from
+multiplying the report's wall-clock retry time. The budget is also clamped to
+the report's remaining working timeout, leaving Celery's configured timeout lag
+available for final state persistence. The effective configured budget is at
+least one second longer than `SLACK_API_TIMEOUT`.
+
+To avoid posting the same report twice, Superset does not replay terminal
+`chat.postMessage` or `files.completeUploadExternal` operations after ambiguous
+server or transport failures. Explicit Slack HTTP 429 responses remain
+retryable. These delivery settings and semantics apply to Slack v2 reports and
+legacy text-only Slack delivery, independently of the

 Superset automatically retries webhook deliveries on `429 Too Many Requests` and `5xx` server errors using exponential backoff. Retries are bounded to roughly 120 seconds of cumulative wall-clock time (worst case ~210 seconds, because the bound is checked against the time elapsed before each attempt, so the final request can begin just under the limit and still run its full request timeout), after which the delivery is abandoned.

+
+# Dashboard Performance
+
+A dashboard's perceived speed is determined by three independent things: how
+many charts have to render, how many queries the backend can execute
+concurrently, and how quickly the underlying data warehouse can return
+results. Superset gives you levers for the first two; the third belongs to
+your warehouse. This page covers the dashboard-side levers and the practical
+guidance around them.
+
+## Is there a maximum chart count per dashboard?
+
+**No hard limit is enforced** — Superset has no configuration key that
+caps the number of charts on a dashboard. In practice, dashboards behave
+well up to a few dozen charts. Beyond that, you'll typically feel friction
+on the initial load and during cross-filter / time-range updates, even with
+the lazy-loading optimizations described below.
+
+Rough thresholds to keep in mind:
+
+- **Under ~25 charts**: usually no perceptible problem.
+- **25–50 charts**: still fine, but you start to want tabs to break the
+  page into chunks the user actually looks at.
+- **Over ~50 charts**: split into multiple dashboards or use tabs
+  aggressively. The bottleneck is rarely Superset itself — it's the
+  warehouse executing dozens of queries in parallel and the browser
+  rendering dozens of chart frames.
+
+These are guidelines, not guarantees. A dashboard of 100 sparkline-style
+charts hitting a fast cache behaves very differently from a dashboard of
+20 heavy aggregations against a cold warehouse.
+
+## Lazy rendering — `DASHBOARD_VIRTUALIZATION`
+
+Superset's dashboard layout is virtualized at the row level. Charts that
+are far below the user's current scroll position render a placeholder
+instead of their visualization until the user scrolls them into view, and
+go back to a placeholder if scrolled well past. The chart component itself
+stays mounted throughout — only the visualization is swapped for a
+placeholder — so this alone does **not** reduce backend query load; see
+[Deferred data fetch](#deferred-data-fetch--dashboard_virtualization_defer_data)
+below for that. This is on by default.
+
+**Feature flag**: `DASHBOARD_VIRTUALIZATION` (default: `True`)
+
+The flag is `stable` and marked for path-to-deprecation — meaning the
+behavior will eventually be non-optional, but the flag still exists so
+operators can disable it if a specific layout misbehaves.
+
+**Behavior** (from `superset-frontend/src/dashboard/components/gridComponents/Row/Row.tsx`):
+
+- A chart's visualization is rendered when its row scrolls within **1
+  viewport height** of the visible area.
+- A chart's visualization is swapped back for a placeholder when its row
+  scrolls more than **4 viewport heights** away from the visible area.
+- Tabs that aren't currently selected don't render their content at all
+  (see below).
+- The placeholder-swap-back is skipped in **embedded** mode (so an
+  embedded dashboard keeps its charts rendered once they've been seen,
+  which avoids re-rendering on scroll-up). Both halves are skipped for
+  **headless / bot** rendering (so screenshot / report jobs load every
+  chart).
+
+## Deferred data fetch — `DASHBOARD_VIRTUALIZATION_DEFER_DATA`
+
+By default, `DASHBOARD_VIRTUALIZATION` only controls whether a chart's
+*visualization* is rendered — the chart component still mounts and issues
+its data request immediately, regardless of scroll position.
+`DASHBOARD_VIRTUALIZATION_DEFER_DATA` is a supplementary flag that skips
+the data request itself for charts that aren't currently in view, useful
+for backends where opening a connection or compiling a query is expensive
+even if the result would be thrown away. It only has an effect when
+`DASHBOARD_VIRTUALIZATION` is also enabled — with virtualization off,
+every chart is treated as in view, so there's nothing left to defer.
+
+**Feature flag**: `DASHBOARD_VIRTUALIZATION_DEFER_DATA` (default: `False`)
+
+Enable this if you see warehouse load spike on dashboard *open* even
+though most charts are off-screen.
+
+## Per-tab lazy loading
+
+**This is on by default and has no flag.** A tab's content is not rendered
+until the user activates that tab, so charts inside an unselected tab do
+not fetch data on dashboard open. When the user clicks the tab, that
+tab's charts mount and fetch in the normal way.
+
+Practically: tabs are the single most effective tool for a large
+dashboard. Splitting 60 charts across 4 tabs effectively turns dashboard
+open into "load ~15 charts," and the remaining ones lazy-load only if the
+user goes looking.
+
+## Is there a switch to cap concurrent chart queries?
+
+**No.** Superset does not implement a frontend-side concurrent-request
+limiter. Each chart issues its own data request when it mounts, and the
+browser handles parallelism — typically ~6 in-flight requests per origin
+under HTTP/1.1, though HTTP/2 or HTTP/3 (if your deployment terminates
+TLS that way) can multiplex considerably more over a single connection.
+Backend throughput is bounded by your
+Gunicorn worker count for synchronous query execution, or by your Celery
+worker pool when [async queries](./async-queries-celery.mdx) are enabled.
+
+If you need to throttle warehouse load, the right place is:
+
+1. The warehouse itself (connection pool / concurrency limits).
+2. Superset's Celery configuration (smaller worker pool when async
+   queries are on).
+3. Splitting heavy charts across tabs or separate dashboards (each
+   dashboard load only fetches what's visible).
+
+## Splitting strategies
+
+When a dashboard outgrows comfortable performance, the options in order
+of effort:
+
+**1. Move sections into tabs.** Same dashboard, but only the active tab's
+charts fetch. This is the cheapest change and often the only one needed.
+
+**2. Cache aggressively.** A Redis cache backend (see
+[Caching](./cache.mdx)) means repeat dashboard loads serve from cache
+rather than re-hitting the warehouse. This is especially impactful for
+dashboards opened by many users in close succession.
+
+**3. Enable async queries.** [Async query execution](./async-queries-celery.mdx)
+via Celery decouples query duration from request lifetime, so a slow
+chart doesn't block the page. The user sees other charts come in as
+their queries complete.
+
+**4. Split into multiple dashboards.** Group related charts into purpose-
+specific dashboards rather than one mega-dashboard. Link them from a
+landing dashboard or a navigation menu.
+
+**5. Pre-aggregate at the warehouse level.** If the same expensive
+aggregation appears across many charts, materialize it as a view or
+scheduled table in the warehouse so each chart query is a cheap lookup.
+
+## Operational notes
+
+- The feature flags above are set in `superset_config.py`, e.g.:
+
+  ```python
+  FEATURE_FLAGS = {
+      "DASHBOARD_VIRTUALIZATION": True,
+      "DASHBOARD_VIRTUALIZATION_DEFER_DATA": True,
+  }
+  ```
+
+- See [Feature Flags](./feature-flags.mdx) for the full list of supported
+  flags and their lifecycle stages.
+- Server-side screenshot jobs (alerts, scheduled reports, thumbnails)
+  render the dashboard in a headless, webdriver-controlled browser, which
+  intentionally bypasses row virtualization so the rendered artifact
+  includes every chart, not just the ones above the fold. User-triggered
+  "download as image/PDF" is different: it captures whatever's currently
+  rendered in the user's own browser, so it's still subject to
+  virtualization like any other page view. Metadata/YAML dashboard export
+  doesn't render the frontend at all, so virtualization doesn't apply to
+  it either.

+#### Looking Up Subjects via API
+
+Superset exposes a read-only REST API for resolving subjects:
+
+```
+GET /api/v1/security/subject/
+```
+
+The main use case is **id mapping** — given a user, role, or group id, callers (including
+extensions) can look up the corresponding subject entity, and vice versa. Access is gated by
+the `can_read` permission on the `Subject` resource, which is granted to **Admins only** by
+default, since subjects enumerate every user, role, and group on the instance. Callers without
+that permission receive a `403`. Only `GET` (list, get, info) is exposed — there is no create,
+update, or delete, because subjects are derived automatically from users, roles, and groups and
+kept in sync internally.
+
+**Resolve the subject for a given principal id** using [Rison](https://github.com/Nanonid/rison)
+query syntax:
+
+```
+GET /api/v1/security/subject/?q=(filters:!((col:user_id,opr:eq,value:5)))

+GET /api/v1/security/subject/?q=(filters:!((col:active,opr:eq,value:!t)))
+```
+
+The `type` column is an integer enum: `1` for User, `2` for Role, `3` for Group
+(`superset.subjects.types.SubjectType`).
+
+**Search by label:**
+
+```
+GET /api/v1/security/subject/?q=(filters:!((col:label,opr:subject_all_text,value:finance)))
+```
+
+Each subject in the response includes flat scalar ids (`user_id`, `role_id`, `group_id`) rather
+than a nested object, so callers can match directly on whichever id they already have — only the
+id field matching the subject's `type` is populated; the others are `null`.

+# Mobile Experience
+
+Superset ships an optional, consumption-only mobile experience for viewing
+dashboards on phones and other small screens. When enabled, screens below
+768px wide get a layout built for touch: dashboards render their charts
+stacked full-width, navigation collapses into a drawer, and dashboard
+filters open in a slide-out panel.
+
+The mobile experience is **read-only by design**. It is aimed at consumers
+of analytics — people checking a dashboard from a phone — not at dashboard
+authors. Authoring surfaces (chart builder, SQL Lab, dataset management,
+and administrative screens) remain desktop-only.
+
+## Enabling the mobile experience
+
+The mobile experience is gated behind the `MOBILE_CONSUMPTION_MODE` feature
+flag, which is off by default. Enable it in your `superset_config.py`:
+
+```python
+FEATURE_FLAGS = {
+    "MOBILE_CONSUMPTION_MODE": True,
+}
+```
+
+With the flag disabled, Superset renders identically at every screen size,
+and phones display the desktop layout scaled down (the pre-existing
+behavior). The flag also controls whether Superset serves a viewport meta
+tag, which is required for mobile browsers to apply the responsive layout
+at their native width.
+
+## What works on mobile
+
+| Area | Mobile behavior |
+| --- | --- |
+| **Dashboards** | Charts stack vertically at full width, sized to the screen. Tab bars are sticky and swipeable. Native filters open in a drawer via the filter icon in the header. |

+| **Home** | Recents (dashboards only) and dashboard cards; desktop-only sections are hidden. |

+
+# Number Formatting
+
+Most chart types expose a **Number format** control (labeled **D3 Format**, **Y Axis Format**, or similar depending on the chart) wherever a metric or numeric axis can be formatted. This is available from the **Customize** tab, or from the metric's popover editor, depending on the chart type. Selecting one of the built-in presets below applies that formatting to the values Superset renders in the chart.
+
+When an axis format control's chart has **Comparison display** set to **Percentage** (e.g. period-over-period comparisons), that control's choices are narrowed to percentage-only presets, hiding `SMART_NUMBER`, `~g`, and the duration/memory/length presets.
+
+You can also type a custom [D3 format string](https://github.com/d3/d3-format) directly into the control if none of the presets fit your needs.
+
+## Built-in presets
+
+### General
+
+| Key | Description |
+| --- | --- |
+| `SMART_NUMBER` | Adaptive formatting — automatically picks a reasonable precision based on the value |
+| `~g` | Original value, using D3's general-format specifier (trims trailing zeros; may switch to exponential notation for very large or small values) |
+
+### D3 format strings
+
+These are raw [D3 format specifiers](https://github.com/d3/d3-format#locale_format). The dropdown shows a live preview of each one against a sample value.
+
+| Format spec | What it does |
+| --- | --- |
+| `,d` | Integer, comma-grouped thousands |
+| `.1s` | SI-prefix notation, 1 significant digit |
+| `.3s` | SI-prefix notation, 3 significant digits |
+| `,.1%` | Percentage, 1 decimal place, comma-grouped |
+| `.2%` | Percentage, 2 decimal places |
+| `.3%` | Percentage, 3 decimal places |
+| `.4r` | Rounded to 4 significant digits |
+| `,.1f` | Fixed-point, 1 decimal place, comma-grouped |
+| `,.2f` | Fixed-point, 2 decimal places, comma-grouped |
+| `,.3f` | Fixed-point, 3 decimal places, comma-grouped |
+| `+,` | Comma-grouped, always shows the sign |
+| `$,.2f` | Currency, 2 decimal places, comma-grouped |
+
+### Duration
+
+| Key | Description |
+| --- | --- |
+| `DURATION` | Duration in ms (`66000` => `1m 6s`) |
+| `DURATION_SUB` | Duration in ms, with sub-second precision (`1.40008` => `1ms 400µs 80ns`) |
+| `DURATION_COL` | Duration in ms, colon-separated (`10500` => `0:00:10.5`) |
+
+### Memory
+
+| Key | Description |
+| --- | --- |
+| `MEMORY_DECIMAL` | Memory in bytes, decimal (`1024B` => `1.024kB`) |
+| `MEMORY_BINARY` | Memory in bytes, binary (`1024B` => `1KiB`) |
+| `MEMORY_TRANSFER_RATE_DECIMAL` | Memory transfer rate in bytes, decimal (`1024B` => `1.024kB/s`) |
+| `MEMORY_TRANSFER_RATE_BINARY` | Memory transfer rate in bytes, binary (`1024B` => `1KiB/s`) |
+
+### Distance / length
+
+| Key | Description |
+| --- | --- |
+| `LENGTH` | Length in meters, converted to kilometers (`12345m` => `12.35km`) |
+| `LENGTH_CM_KM` | Length in centimeters, converted to kilometers (`12345678cm` => `123.46km`) |
+| `LENGTH_CM_M` | Length in centimeters, converted to meters (`12345cm` => `123.45m`) |
+
+Use these when a metric's underlying values are stored in meters or centimeters but are easier to read at a coarser unit — for example, distances traveled, cable/pipe lengths, or elevation changes.
+
+## Currency
+
+Some chart types also expose currency-specific formatting, including a dynamic mode that reads the currency from a column value. See [Dynamic Currency Formatting](./creating-your-first-dashboard#dynamic-currency-formatting) for details.

+# (docker.yml's docker-build job only runs when the change detector's
+# docker/python/frontend outputs are true, and the PR build matrix never
+# includes py311/py312 at all, so a regression here would otherwise go
+# unnoticed until the fix actually runs on master) without duplicating -
+# and risking drift from - the logic used by the real build step.
+#
+# supersetbot's "py311"/"py312" presets pin their own --build-arg PY_VER,
+# which lands ahead of --extra-flags on the assembled buildx command line;
+# docker/buildx keeps the last value for a repeated --build-arg key, so
+# appending PY_VER here would override supersetbot's pin and silently make
