+- `SAMPLES_ROW_LIMIT` is now the default for `/datasource/samples` requests without a valid explicit `per_page`, rather than a hard per-request ceiling; explicit limits are honored up to the existing global row-limit ceiling, matching `/chart/data` SAMPLES requests.
+- The `cockroachdb` extra (`pip install apache-superset[cockroachdb]`) now installs `sqlalchemy-cockroachdb` instead of the abandoned `cockroachdb` package, whose SQLAlchemy dialect could not be imported under SQLAlchemy 2.0. Existing environments with the old package installed should `pip uninstall cockroachdb && pip install sqlalchemy-cockroachdb` (or simply reinstall the extra) to restore CockroachDB connectivity.

+### MCP tool results preserve stored string values
+
+Structured MCP tool results no longer add `<UNTRUSTED-CONTENT>` wrappers or
+rewrite delimiter-looking text inside string fields. Tool-result content remains
+user-controlled data, but clients must convey that trust boundary outside domain
+values instead of recognizing or removing marker strings.
+
+Clients that handled the former delimiter convention should stop stripping marker
+text: the same text can be legitimate stored content. Response models and content
+types are unchanged, and no metadata-database migration is required. Automated
+read-modify-write workflows should be paused or pinned away from older instances
+until every serving instance is upgraded; a mixed-version response has no reliable
+signal that tells a client whether its text is decorated. Redis-backed MCP response
+caches use a new internal namespace after the upgrade, so upgraded instances do not
+reuse older cached results.
+
+Values that a client already wrote back with presentation wrappers cannot be
+distinguished safely from intentional content. Operators should review possible
+`<UNTRUSTED-CONTENT>` / `</UNTRUSTED-CONTENT>` wrappers and
+`[ESCAPED-UNTRUSTED-CONTENT-OPEN]` /
+`[ESCAPED-UNTRUSTED-CONTENT-CLOSE]` substitutions rather than applying an automatic
+marker-removal migration.

+- [42930](https://github.com/apache/superset/pull/42930): Dataset import data-URI fetches no longer honor an HTTP(S) proxy when `DATASET_IMPORT_ALLOW_INTERNAL_DATA_URLS` is `False` (the default): the connection is now made directly to the destination so the peer-address check validates the real target instead of a proxy's. Deployments that require an egress proxy to reach legitimate external data URLs for dataset import should set `DATASET_IMPORT_ALLOW_INTERNAL_DATA_URLS = True` or otherwise ensure those URLs resolve without one.
 - [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.
+- [42429](https://github.com/apache/superset/pull/42429): The Country Map chart's Iran GeoJSON now gives Alborz province its own ISO 3166-2 code, `IR-32`, instead of `IR-30`. `ISO` is the join key used to color/filter provinces on this chart, so any existing dataset keyed on `IR-30` for Alborz will silently stop matching after upgrading; re-key that data to `IR-32`.
+- [43388](https://github.com/apache/superset/pull/43388): The MCP service now refuses to start (`MCPAuthConfigError`) if `MCP_DEV_USERNAME` and `MCP_AUTH_ENABLED = True` are both set, and separately if `MCP_AUTH_ENABLED = True` but no usable JWT key material is configured (RSA key/JWKS, or an explicit `MCP_JWT_SECRET` for HMAC) — both previously started with authentication silently weaker than configured. Deployments combining a dev-mode username with JWT auth enabled, or enabling JWT auth without key material, must pick one before upgrading: unset `MCP_DEV_USERNAME` for a real auth deployment, or unset `MCP_AUTH_ENABLED` (or configure the key material) for a dev-mode one. Response caching (`MCP_CACHE_CONFIG["enabled"] = True`) now also excludes every tool with a side effect by default, not only a partial list, so a previously-cached mutating tool call is no longer served from cache; no config change is needed to pick this up.
 - [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.

+MySQL/Postgres, TimescaleDB) inherit the same support, on the same
+not-yet-independently-verified basis. Picking one of these aggregates on a
+database that has not opted in returns a clear "not supported on this
+database" error rather than a failed query. See

Every scheduled evaluation writes a provisional, content-free record to the new `purge_audit_log` table before the cascade starts. Meaningful retained outcomes survive the entity they name. Blocked audit records carry a stable machine-readable `reason` code (`report_schedule`, `user_attribute`, or `cascade_integrity_failure` for an unexpected cascade failure caused by a database integrity constraint) so the audit table alone answers why an entity was not purged; records finalized before the column existed keep a NULL reason. Apply the migration before rolling out the new code: the audit model declares the column, so a worker on the new code with an un-migrated table fails its write-ahead write and the scheduled purge fails closed until the migration lands. During a rolling deploy, workers still on the old code write reason-less blocked rows and suppress on status alone; both effects are self-healing, since a NULL-reason record never matches a reason code and the next all-new-code run re-anchors the entity. Consecutive scheduled evaluations blocked with the same status **and reason** suppress only the redundant current provisional record — a reason change writes one new blocked record carrying the new code; completed outcomes, outcome transitions, and every force-purge attempt remain independent and immutable. Retained transition records are not automatically expired, so entities whose block reason changes repeatedly can accumulate multiple audit rows.

+### Tool Result Value Contract
+
+Structured tool results preserve Superset domain values exactly. In particular,
+string fields are not wrapped in trust delimiters, and text that resembles a
+delimiter is returned as literal application data. This lets clients safely use a
+read result as the basis for an update without persisting presentation markup.
+
+All tool-result content should still be treated as user-controlled data with no
+instruction authority. MCP clients should communicate that trust boundary through
+their model instructions or presentation layer, outside the returned field values;
+fixed or generated marker strings inside a value are ambiguous and must not be used
+as a trust signal.
+
+For compatibility, clients that supported the former
+`<UNTRUSTED-CONTENT>` convention should stop recognizing or stripping those strings.
+The response schemas and content types have not changed. Because marker-looking text
+can be legitimate application data, a client cannot reliably distinguish a legacy
+decorated response from a clean one. Pause automated read-modify-write workflows, or
+route them only to upgraded instances, until every serving instance is upgraded.
+
+Redis-backed MCP response caches include an internal response-contract namespace, so
+an upgraded instance does not reuse responses cached by an older release. Older
+instances can still return legacy values while they remain in service. After the
+upgrade, review previously written values for wrapper text and both
+`[ESCAPED-UNTRUSTED-CONTENT-OPEN]` and
+`[ESCAPED-UNTRUSTED-CONTENT-CLOSE]`; do not remove these strings automatically,
+because they may be intentional content.

+
+Disabled chart types stay registered but are filtered out at lookup time: they're never listed in `generate_chart`'s supported chart types, and `generate_chart` calls for them are rejected. `get_chart_type_schema` consults its own static schema/example map rather than the registry filter, so a disabled chart type's schema remains queryable through that tool even though `generate_chart` will reject it.

+
+For per-request control (A/B tests, gradual rollout, entitlement checks), set `MCP_CHART_PLUGIN_ENABLED_FUNC` to a callable. It's evaluated as `enabled_func(chart_type: str) -> bool` on every registry lookup, and it takes precedence over `MCP_DISABLED_CHART_PLUGINS` when set:

+The callable must be cheap and in-process (consult already-loaded feature flags or request-local context) -- do not perform network I/O per call. If it raises, the registry fails closed (the plugin is hidden) and logs a warning.

+#### Extending Editorship with EXTRA_EDITORS_RESOLVER
+
+Deployments that grant edit access to a dashboard or chart through a mechanism outside
+Superset's own Subject-based `editors` list — for example, a folder-permission system or an
+internal directory service — can plug that logic in with `EXTRA_EDITORS_RESOLVER`:
+
+```python
+def extra_editors_resolver(resource):
+    # `resource` is the Dashboard or Slice instance being checked.
+    # Return Subject instances, raw subject ids, or dicts with an `id` key.
+    return [...]
+
+
+EXTRA_EDITORS_RESOLVER = extra_editors_resolver
+```
+
+The resolver's result is unioned with the resource's own `editors` for editorship checks: it
+feeds `is_editor`, `raise_for_editorship`, save-as, and soft-delete restore. When
+`EXTRA_EDITORS_RESOLVER` is configured, the usual lockout-prevention behavior — automatically
+re-adding a non-admin who removes themselves from a resource's editors — is skipped, since the
+deployment has its own way of keeping the resource editable. This skip is global to the setting,
+not per-resource: it still applies on a resource where the resolver currently returns no
+subjects, so a resolver that can't guarantee an alternate editor for every resource can let the
+last editor remove themselves and leave it uneditable by non-admins.
+
+Resolved subject ids are also surfaced as `extra_editors` in the chart and dashboard `GET`
+responses, so API clients can distinguish resolver-granted editorship from the resource's own
+`editors` list. This field is attached after serialization and isn't part of the OpenAPI response
+schema, so generated API clients won't see it as a typed field.
+
+Because the resolver is arbitrary per-deployment Python rather than a SQL-expressible condition,
+editorship it grants cannot be reflected in list-view filtering (for example, the soft-deleted
+archive is scoped to editors via a SQL query). It does still run once per row on chart and
+dashboard list responses to populate `extra_editors`, so a slow or unavailable external resolver
+affects ordinary list requests, not just direct per-object checks.

+#### RLS Indicator in the Dataset List and Explore
+
+When a dataset has one or more RLS filters that apply to it, Superset shows a lock
+icon badge next to the dataset name in the **Datasets** list and next to the dataset
+selector in **Explore**. Hovering over the badge shows a tooltip listing each
+applicable filter's name, filter type (Regular or Base), group key (if any), assigned
+subjects (labeled "Roles" in the tooltip, but may include users and groups too), and
+clause.
+
+This badge also surfaces filters that are inherited from the physical tables
+referenced by a virtual (SQL-based) dataset, as described above. Inherited filters
+are marked "from underlying table" in the tooltip, and a summary note is shown
+whenever any of the listed filters are inherited rather than assigned directly to
+the dataset. Inherited-filter detection depends on Superset's SQL parser being able
+to identify the referenced tables and match them to a physical dataset by name,
+schema, and database, so it's best-effort: unparseable or unmatched references won't
+surface a filter on the badge even if one would apply at query time.
+
+The badge is a visibility aid only — it does not change which filters are applied to
+a query. Use the RLS REST API described below if you need to confirm exactly which
+filters affect a dataset.

+- **Export screenshot (jpeg)** — a single-click JPEG screenshot of the chart.
+- **Export screenshot (png)** — opens a submenu with **Transparent background** and **Solid background** options. The solid option uses the current theme's background color. PNG produces a higher-quality image than the JPEG export.
+- **Export as PDF** — downloads the chart as a PDF file.

When Superset is not embedded, it rewrites the origin of any permalink URL it generates to `window.location.origin` before showing it to the user, which keeps a proxied or subdirectory-deployed Superset from handing out a permalink that points at an internal hostname the user's browser can't reach.

+# SIP: System-wide MEDIAN, Sample Standard Deviation, and Sample Variance metric aggregates
+
+## [DRAFT — proposal for discussion]
+
+This document now has an accompanying implementation in this PR, for the
+proposed mechanism plus a first, empirically-verified engine set (Postgres,
+MySQL, DuckDB, Redshift by inheritance). It is intended to seed discussion on
+whether this is the right shape and scope before it goes up for a formal SIP
+vote, not to pre-empt that discussion, the code exists so reviewers have a
+concrete design to react to rather than a description of one.
+
+## Motivation
+
+Before #41184 (SIP-216, the non-additive-totals fix), the Pivot Table chart
+exposed an "Aggregation function" control with 18 choices, including
+`Median`, `Sample Standard Deviation`, `Sample Variance`, `First`, `Last`,
+`Count Unique Values`, and `List Unique Values`. #41184 deleted that control
+wholesale, and deliberately so: it re-aggregated already-aggregated cell
+values to compute totals/subtotals, which is exactly the class of bug
+SIP-216 fixed (summing per-group averages, averaging per-group medians, etc.
+produces silently wrong totals). #42761 subsequently restored the one piece
+of that control's functionality that was cleanly separable from the
+correctness bug, the "show as % of row/column/total" display option,
+redesigned as a decoupled, post-hoc-only `showValuesAs` control.
+
+A user has since noticed that several of the other pre-#41184 options never
+came back. Checking today's metric aggregate list (`AVG, COUNT,
+COUNT_DISTINCT, MAX, MIN, SUM`, see
+`superset-frontend/packages/superset-ui-core/src/query/types/Metric.ts`),
+most of these have a reasonable equivalent already: `Count Unique Values`
+maps to `COUNT_DISTINCT`; `Count`/`Average`/`Max`/`Min` are already standard
+aggregates; the two "fraction of" variants are already covered by
+`showValuesAs`. But `Median`, `Sample Standard Deviation`, and `Sample
+Variance` have no equivalent today anywhere in Superset, not just in Pivot
+Table, in any chart type, since the aggregate list is shared across the
+whole app.
+
+This is a real, currently-live gap, not a hypothetical one:
+`superset/mcp_service/chart/chart_utils.py`, `schemas.py`, and
+`prompts/create_chart_guided.py` already treat `STDDEV`, `VAR`, `MEDIAN`,
+and `PERCENTILE` as valid aggregate values in their own validation and
+documentation, but those values are never recognized by
+`superset/connectors/sqla/models.py`'s `sqla_aggregations` dict (the actual
+mapping from aggregate name to SQL), so an AI agent using the MCP tool to
+build a chart with `"aggregate": "STDDEV"` today creates a chart that
+**errors at query time** with "Adhoc metric aggregate is invalid." This SIP
+proposes closing that gap for real, at the source, rather than patching
+around it in MCP.
+
+## Proposed change
+
+Add `MEDIAN`, `STDDEV_SAMP`, and `VAR_SAMP` as first-class, system-wide
+metric aggregates, available anywhere a metric aggregate is chosen (every
+chart type, SQL Lab metric picker, MCP), not as a Pivot-Table-specific
+control.
+
+**Why this is safe with respect to SIP-216, and needs no Pivot-Table-specific
+code at all:** Pivot Table's non-additive-totals machinery
+(`superset-frontend/plugins/plugin-chart-pivot-table/src/plugin/utilities.ts`)
+already classifies any metric aggregate not in `ADDITIVE_AGGREGATES = {SUM,
+COUNT, MIN, MAX}` as non-additive, which routes totals/subtotals through the
+correct DB-`GROUPING SETS`-rollup path rather than client-side
+re-aggregation (`AVG` and `COUNT_DISTINCT` already go through this path
+today). `MEDIAN`/`STDDEV_SAMP`/`VAR_SAMP` fall into that bucket
+automatically, with zero changes needed to the additivity logic. So once
+these are valid, buildable SQL aggregates, Pivot Table (and every other
+chart) gets correct behavior for free. This is the version of "restore the
+control" that does not reopen the bug that was just fixed.
+
+**Where the actual change needs to land, and what this PR does:**
+
+1. **Done.** `superset-frontend/packages/superset-ui-core/src/query/types/Metric.ts`,
+   extended the `Aggregate` type.
+2. **Done.** `superset-frontend/src/explore/constants.ts`, added to `AGGREGATES`
+   (drives `AGGREGATES_OPTIONS`, the dropdown in `AdhocMetricEditPopover`).
+3. **Done**, but not consolidated. `superset/connectors/sqla/models.py`
+   (`sqla_aggregations`) and `superset/models/helpers.py`
+   (`ExploreMixin.sqla_aggregations`) are both wired to consult the new
+   `BaseEngineSpec.get_extended_aggregation_func`, in addition to their
+   existing 6-aggregate dict, so neither's original, already-tested behavior
+   changed. They remain two separate dicts, consolidating them into one
+   source of truth is left as a follow-up (see Open questions).
+4. **Done**, and it surfaced a second, smaller bug on top of the one this SIP
+   opened with: MCP's own aggregate names (`STDDEV`, `VAR`) never matched any
+   real Superset aggregate, before or after this PR, they were always going
+   to error regardless of what this SIP does. `superset/mcp_service/chart/*`
+   now accepts the old shorthand as an alias, normalized to the real,
+   unambiguous names (`STDDEV_SAMP`, `VAR_SAMP`) this PR ships, and the guided
+   prompt text points at the correct names going forward. `MEDIAN`/
+   `PERCENTILE` were already spelled correctly in MCP; `PERCENTILE` remains
+   unimplemented (it needs a parameter this schema has no field for) and is
+   unchanged by this PR, out of scope here.
+
+**The part that needs real engineering care, this must not be a blind
+`sa.func.MEDIAN` / `sa.func.STDDEV_SAMP` / `sa.func.VAR_SAMP`:**
+
+`sqla_aggregations` today is a flat, engine-unaware dict (`sa.func.AVG`,
+etc., SQLAlchemy emits whatever function name it is given, with zero
+validation that the target dialect actually has it). Superset already has
+precedent for exactly this class of per-engine capability difference:
+`BaseEngineSpec.supports_grouping_sets` and `_time_grain_expressions`, both
+introduced by #41184 itself. This SIP proposes the same shape, a new
+per-engine-overridable mechanism (for example
+`BaseEngineSpec.get_aggregate_sql(aggregate, column)` with a sensible
+default, overridden per engine spec where the default does not hold),
+rather than a single hardcoded dict.
+
+Verified findings so far (via `sqlglot.transpile`, cross-checked against
+known engine docs; **not** exhaustively tested against live databases, that
+is necessary follow-up work this SIP alone cannot complete):
+
+| Engine | `MEDIAN(x)` | `STDDEV_SAMP(x)` | `VAR_SAMP(x)` |
+|---|---|---|---|
+| Postgres | `PERCENTILE_CONT(0.5) WITHIN GROUP (ORDER BY x)` | native | native |
+| MySQL | no native equivalent, needs explicit "unsupported" handling, not a blind emit | native | MySQL's `VARIANCE()` is an alias for `VAR_POP` (population), not `VAR_SAMP` (sample); a naive dialect-name substitution would silently compute the wrong statistic and needs an explicit, verified expression instead |
+| SQLite | only if the specific build was compiled with the (non-default) `SQLITE_ENABLE_PERCENTILE` extension (added in SQLite 3.43, 2023), cannot be assumed available | not available in core SQLite | not available in core SQLite |
+| BigQuery / Snowflake / DuckDB / Redshift / Oracle / T-SQL / Databricks / Spark | native `MEDIAN(x)` | native | native on BigQuery/Snowflake/Databricks/Spark, where `VARIANCE` is correctly sample variance; T-SQL has no function named `VARIANCE` at all and needs `VAR(x)` instead |
+| Trino / Presto / Hive | `PERCENTILE_CONT` / `approx_percentile` (dialect- and exactness-dependent) | native | `variance` is correctly sample variance per Trino/Presto docs |
+
+This table is deliberately not exhaustive, Superset has roughly 75
+`db_engine_specs` files. The proposed default (`BaseEngineSpec`) should be
+the safe choice (mark unsupported, surface a clear user-facing error) rather
+than an optimistic one, with individual engine specs opting in once
+verified. Ship for the handful of engines above first, extend
+opportunistically.
+
+**`Count Unique Values`, `First`, `Last`, `List Unique Values`, explicitly
+out of scope for this SIP:**
+
+- `Count Unique Values` needs no work, it is already `COUNT_DISTINCT`.
+- `First`/`Last` have no well-defined, unambiguous meaning as a plain
+  `GROUP BY` aggregate without an explicit ordering; most engines only
+  support this via window functions (`FIRST_VALUE`/`LAST_VALUE` `OVER
+  (ORDER BY ...)`) or do not support it as a simple aggregate at all
+  (Postgres has neither built in). Restoring this properly would mean
+  designing an "order by" sub-control on the metric, a real, separate
+  feature, not a one-line aggregate addition. Proposed as a follow-up SIP if
+  there is demand.
+- `List Unique Values` maps to the `STRING_AGG`/`GROUP_CONCAT`/`LISTAGG`/
+  `ARRAY_AGG(DISTINCT ...)` family, real dialect differences, plus an open
+  UX question (unbounded cell content for high-cardinality columns).
+  Proposed as a follow-up SIP.
+
+## New or changed public interfaces
+
+- New `Aggregate` values (`MEDIAN`, `STDDEV_SAMP`, `VAR_SAMP`) selectable
+  anywhere the standard metric control appears, every chart type, not just
+  Pivot Table.
+- New `BaseEngineSpec` extensibility point for per-engine aggregate SQL
+  generation (exact shape TBD in implementation, likely mirrors
+  `_time_grain_expressions`).
+- No REST API surface changes beyond the existing metric aggregate field
+  accepting new values.
+
+## Migration plan and compatibility
+
+No new tables/columns needed for the aggregate addition itself.
+
+Restoring prior chart settings, the way #42761 restored `show_values_as` for
+charts that had it before #41184, is murkier here than it was for that PR
+and needs its own design pass: the old `aggregate_function` was a single
+Pivot-Table-level setting applied uniformly to every metric on the chart,
+not a per-metric property. A chart that had `aggregate_function: Median`
+before #41184, with a metric of `SUM(sales)`, was already silently wrong
+under the old architecture (that is the bug that was fixed); mechanically
+rewriting its metric to `MEDIAN(sales)` on upgrade would change what the
+chart's leaf cells display, not just its totals, which may not match user
+intent. This SIP proposes a best-effort, flagged-for-review migration
+(surface affected charts to admins rather than silently rewriting them)
+rather than a fully automatic one-to-one restoration.
+
+## Rejected alternatives
+
+- **Restoring the old `aggregateFunction` Pivot-Table control as-is.**
+  Rejected: this is the literal mechanism SIP-216 removed because it
+  reintroduces incorrect totals for non-additive metrics. Any fix has to go
+  through the metric's own aggregate, not a separate pivot-level override.
+- **Routing all metric SQL generation through `sqlglot` expression-building
+  instead of SQLAlchemy's `sa.func`.** More architecturally thorough (would
+  give correct dialect syntax for free across more of the roughly 75 engine
+  specs), but a much larger, more invasive change to a hot path used by
+  every chart query. Noted as a possible future direction, not this SIP's
+  scope; this SIP proposes the smaller, `supports_grouping_sets`-shaped
+  extensibility point instead.
+
+## Open questions
+
+- **Resolved for this PR, worth confirming as the community's preferred
+  shape:** implemented as `BaseEngineSpec._extended_aggregations` (a
+  `{aggregate_name: sqla_column -> sqla_column}` dict) plus a
+  `get_extended_aggregation_func` accessor, set on the concrete or shared
+  base engine spec class per engine (e.g. on `PostgresBaseEngineSpec` so
+  Redshift inherits it, but *not* on `PrestoBaseEngineSpec` so Hive/Spark/
+  Databricks don't silently inherit unverified behavior, mirroring how
+  `supports_grouping_sets` is opted into per-concrete-engine there today).
+  Did not route through the `superset/sql/dialects/` sqlglot-based layer;
+  that layer is for SQL Lab parsing, wiring it into chart-metric query
+  building felt like a separate, larger change from this SIP's scope.
+- **Still open, not addressed in this PR:** how aggressively should
+  `MEDIAN` degrade on engines without a native or exact equivalent?
+  Trino/Presto/Hive were left unimplemented (unsupported) specifically to
+  avoid silently answering this with an approximate function
+  (`approx_percentile`) that changes the semantics of what a user asked
+  for. If someone wants `MEDIAN` on those engines, this needs a real
+  decision: require explicit opt-in, show a UI warning, or keep it
+  disallowed.
+- **Resolved for this PR:** left the two `sqla_aggregations` dicts
+  (`connectors/sqla/models.py` and `models/helpers.py`) unconsolidated,
+  both now separately wired to the same new `get_extended_aggregation_func`
+  hook. Consolidating them into one source of truth is real but unrelated
+  cleanup, not bundled here to keep the diff reviewable.
+- **New, from implementation:** only Postgres, MySQL (partial), DuckDB, and
+  Redshift (by inheritance, unverified) ship enabled. BigQuery, Snowflake,
+  Trino, Presto, Hive, Spark, Databricks, Oracle, and T-SQL all have
+  documented (not live-verified) support per the table above but are not
+  yet wired up, each needs the same live-instance verification treatment
+  before being enabled, this PR intentionally didn't guess.

+# (docker.yml's docker-build job only runs when the change detector's
