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

+
 - [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.

+### 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

+formatting: previously the Table post-processor applied `d3NumberFormat` to
+every result format, so CSV/XLSX exports contained pre-formatted strings.

+### 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.

+### 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
+on MSSQL where the rewrite previously raised `AttributeError`.

Slack blocked new apps from `files.upload` in May 2024 and fully retired the method for all apps on November 12, 2025; because the v1 path sends files through `files.upload`, v1 file-bearing sends now fail at the API level — only text-only `chat_postMessage` still works via the legacy path. Grant your Slack bot the `channels:read` and `groups:read` scopes so existing `Slack` recipients can be auto-upgraded to `SlackV2` on next send. Operators who explicitly override the flag to `False`, or whose Slack bot is missing those scopes, will see deprecation warnings while text-only sends continue through the legacy path.

+#### 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
+
+# Number of explicit HTTP 429 responses retried using Slack's Retry-After value
+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
+`ALERT_REPORT_SLACK_V2` feature flag.
+
 ### Webhook integration
 
 Superset can send alert and report notifications to any HTTP endpoint — useful for chat platforms, incident management tools, or custom automation.

+
+# 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.

+
+# 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. |
+| **Dashboard list** | Card view with full-width cards; search and filters open in a drawer. |
+| **Home** | Recents (dashboards only) and dashboard cards; desktop-only sections are hidden. |
+| **Navigation** | A hamburger menu opens a drawer with links to dashboards, theme and language selection, and user info/logout. |

+
+## What doesn't work on mobile
+
+Everything not listed above shows a friendly "This view isn't available on
+mobile" screen with shortcuts back to dashboards and the home page. That
+includes:
+
+- Chart builder (Explore) and chart-level links — chart titles on
+  dashboards are plain text on mobile, and chart entries are filtered out
+  of the home page's Recents feed
+- SQL Lab and query history
+- Creating or editing dashboards, charts, datasets, and databases
+- List views other than dashboards (charts, datasets, saved queries, etc.)
+- Administrative and settings screens
+
+Editing controls are also removed from the screens that *are* supported:
+the dashboard header hides the edit, publish, and favorite controls, and
+dashboard/chart kebab menus are reduced to view-oriented actions.
+
+If a device crosses the 768px threshold — for example, rotating a tablet
+to landscape or resizing a window — the full desktop experience becomes
+available immediately.
+
+## Notes for operators
+
+- The flag is deployment-wide; there is no per-role or per-user targeting.
+- Dashboard permalinks and links shared from desktop resolve normally on
+  mobile as long as they point at dashboards.
+- Embedded dashboards are unaffected: the embedded SDK controls its own
+  layout, and the viewport meta tag is only interpreted by the top-level
+  page.
+- Dashboards loaded with a `standalone` URL param (used for iframe embeds
+  and kiosk-style displays) always render the desktop layout, regardless
+  of viewport width, since the standalone chrome doesn't expose the mobile
+  filter drawer's trigger.

+ * upgrade renamed `.ant-modal-content` to `.ant-modal-container`, the chain

+ * before collapsing to an empty body with only the header and pagination
+ * visible.

+ * Only a real browser sees layout, so this is pinned here rather than in the
+ * DOM-contract unit suite. Because the failure mode is
+ * render-then-collapse, a single "rows are visible" read could pass during
+ * the initial flash — the assertion therefore lets the height settle once,
+ * then requires it to hold across further spaced reads with no more
+ * retrying, so a later or partial collapse cannot be masked by an early-exit
+ * retry that stopped at the first passing sample.
+ *
+ * CI green => the drill modal's table renders rows at a stable, non-collapsed

+ * Crawls every dashboard on the target instance and refreshes viz-picker

+ *
+ * This is a maintenance tool, not a test: charts are DISCOVERED via the
+ * API (dashboards -> charts), so it keeps working as example dashboards
+ * evolve. Every distinct chart found for a viz type gets captured — the
+ * preferred (or alphabetically-first) chart becomes the 512x512
+ * `thumbnail.png`, and each additional distinct chart fills the next
+ * `exampleGallery` slot declared for that viz type, so the gallery shows
+ * real variety instead of the same chart resized. The two static pieces
+ * are the viz type -> image path maps below (VIZ_TYPE_THUMBNAILS,
+ * VIZ_TYPE_GALLERY), which change when a plugin's images or gallery
+ * shape change — never when examples change. Viz types found on
+ * dashboards but missing from both maps, and gallery slots left unfilled
+ * for lack of enough distinct example charts, are reported at the end
+ * without failing the run.
+ *
+ * It only runs when CAPTURE_THUMBNAILS=1 is set, so the regular
+ * Playwright suites never execute it.
+ *
+ * Usage (requires a running Superset with examples loaded):
+ *   npm run playwright:thumbnails

+ *
+ * Notes:
+ * - Dark variants (`thumbnail-dark.png`, `example-dark.jpg`) are captured
+ *   via prefers-color-scheme emulation whenever the sibling file exists;
+ *   if the app ignores the emulation (dark theming disabled) the dark
+ *   file is left untouched.
+ * - A brand-new gallery image (rather than an existing file being
+ *   refreshed) still needs to be registered in the plugin's metadata
+ *   before it renders in the gallery; the capture logs a reminder.
