Merge branch 'main' into issue-4293

* refactor(data-export): extract the withUnit header helper

Both the timeseries and the upcoming table serializers append units to headers (and skip display-only ids like 'short'/'none') — move the helper to its own module.

* feat(data-export): add generic table-model serializer

exportTableData serializes any prepared antd-style table model ({name, key, isValueColumn} columns + record rows) into a SerializedTable — raw values in display order, units on value columns only, blanks for missing cells. Surface-agnostic: QueryTable-based tables, dashboard tables and plain antd tables all adapt in a line or two.

* feat(data-export): add scalar queryRange serializer

exportScalarData takes the queryRange response object (formatForWeb webTables payload) + the builder query and serializes via createTableColumnsFromQuery — the exact preparer QueryTable renders from — so exports inherit the on-screen merge, naming and column order 1:1.

+// Package clickhouseprometheusv2 is the second-generation ClickHouse-backed
+// Prometheus provider. It exists because the v1 provider fetches every raw
+// sample of a query's union window through the remote-read protobuf layer
+// and hands it to the engine — the cost is a function of ingested data, not
+// of the question asked, which is how a dashboard of PromQL panels takes an
+// instance down.
+//
+// Every query runs in one of two ways, decided per query:
+//
+//   - Transpiled: the query is evaluated entirely inside ClickHouse and only
+//     final (or near-final) per-group grid arrays come back, built on the
+//     timeSeries*ToGrid aggregate functions (the supported ClickHouse floor
+//     is >= 25.6, so they are assumed available).
+//   - Engine: the stock promql engine evaluates over this package's native
+//     storage.Querier. This is the path for everything not transpilable.
+//
+// Correctness is the constraint that shaped both paths: a PromQL result that
+// differs from upstream Prometheus is a lost user, so anything that cannot
+// reproduce engine semantics exactly falls back rather than approximate.
+// The rest of this comment is the PromQL -> SQL story, because that mapping
+// is where correctness is won or lost.
+//
+// # The evaluation model the SQL must reproduce
+//
+// A PromQL range query is an instant query evaluated at every grid point
+// t_i = start + i*step, i = 0..(end-start)/step. At each t_i:
+//
+//   - an instant selector resolves to the latest sample in the left-open
+//     lookback window (t_i - lookback, t_i], and to nothing when that latest
+//     sample is a stale marker — even if older real samples sit inside the
+//     window;
+//   - a range selector [r] collects every sample in (t_i - r, t_i], stale
+//     markers excluded;
+//   - offset d shifts both windows to (t_i - d - w, t_i - d].
+//
+// The transpilation invariant follows from this: every transpiled construct
+// produces, per output series, one array with exactly one slot per grid
+// point — slot i holds the value at t_i, NULL means absent. This is what
+// makes composition correct, not just convenient: the engine evaluates
+// these operators independently per t_i, so any representation that gets
+// every slot right gets the whole query right, and spatial aggregation over
+// arrays is sound because it combines values that belong to the same t_i by
+// construction. Slot index i maps back to t_i = start + i*step at scan time
+// (toMatrix). Everything below is about filling those slots with exactly
+// the numbers the engine would compute — and each equivalence was validated
+// against the vendored engine on live data before its shape entered the
+// allowlist; anything unproven stays on the engine path.
+//
+// # Classification: finding what a statement can answer
+//
+// classify walks the parsed AST looking for "core units" — maximal subtrees
+// of the shape
+//
+//	[agg by/without (...)] [fn(] selector[range] [offset d] [)] [op scalar]...
+//
+// classifyCore peels that chain from the outside in: an optional
+// sum/min/max/avg/count aggregation, then one of the allowlisted functions
+// or a bare instant selector, then the selector with its offset; on the way
+// out it accumulates number-literal arithmetic, comparisons (including
+// bool) and unary minus into a scalar-op pipeline. A node qualifies only if
+// its type, arguments and children are in the proven set — an allowlist, so
+// an overlooked construct becomes a fallback instead of a wrong number.
+//
+// Three unit kinds come out of this, each with its own SQL form:
+// unitRange (rate, irate, increase, delta, idelta over a range selector),
+// unitInstant (instant vector selection, bare or comparison-filtered) and
+// unitOverTime (avg/min/max/sum/count/last _over_time).
+//
+// If the entire tree is one unit, the plan is "full": the statement's rows
+// are the query result. Otherwise every maximal unit is cut out and replaced
+// in the expression with a synthetic selector __signoz_transpiled_N__, and
+// the rewritten expression runs in the engine over the units' materialized
+// results ("hybrid") — histogram_quantile, topk, or/and/unless and vector
+// matching keep exact engine semantics while their expensive inputs were
+// aggregated server-side.
+//
+// Classification refuses when exact semantics cannot be guaranteed
+// server-side: the @ modifier anywhere and default-resolution subqueries
+// (their resolution is a server runtime setting the transpiler cannot see);
+// steps or ranges that are not whole seconds (the grid functions take
+// whole-second parameters); grouping by or matching on __name__ in hybrid
+// plans (the synthetic name would leak into results); name-keeping units —
+// bare/comparison instant selectors and last_over_time keep their real
+// __name__ (keepsName), which substitution would replace, so they transpile
+// only as full plans; and every function outside the allowlist (changes,
+// resets, quantile_over_time, absent, native-histogram functions, ...).
+//
+// Units inside a fixed-resolution subquery evaluate on the subquery's own
+// grid instead of the query grid: epoch-aligned multiples of the resolution
+// strictly after outerStart - offset - range, ending at outer end - offset —
+// the exact derivation the engine uses, because a grid shifted by one step
+// changes which samples every window sees.
+//
+// # From one unit to one statement
+//
+// buildUnitSQL renders each unit as a single statement. For
+// sum by (pod) (rate(m{job="api"}[5m])) the skeleton is:
+//
+//	SELECT gkey, sumForEach(grid) AS grid FROM (
+//	    SELECT series.gkey AS gkey,
+//	           timeSeriesRateToGrid(<start>, <end>, <step>, <range>)(fromUnixTimestamp64Milli(unix_milli), value) AS grid
+//	    FROM signoz_metrics.distributed_samples_v4 AS points

+// The time window is the selector's semantics verbatim: strict > on the

+// whole window shifted by the offset. bitAnd(flags, 1) = 0 drops stale
+// markers, which PromQL excludes from range vectors.
+//
+// The inner GROUP BY computes one grid array per series.
+// timeSeriesRateToGrid(start, end, step, range) is a parametric aggregate:
+// fed (timestamp, value) pairs it produces Array(Nullable(Float64)) with one
+// slot per grid point. Correct because it implements the engine's
+// extrapolatedRate decision for decision — counter resets, the zero-point
+// clamp, the extrapolation thresholds, the >= 2 samples rule, the left-open
+// window — verified by feeding identical samples to both and comparing
+// slot for slot: the only difference ever observed is the last bit
+// (ClickHouse's C++ and Go round the same formula differently), which is
+// the floating-point floor, not a semantic gap. irate/delta/idelta map to
+// their own timeSeries*ToGrid functions with the same verification;
+// increase has no function of its own and is emitted as
+// arrayMap(x -> x * <range seconds>, <rate expr>), exact by definition —
+// extrapolatedRate computes the same extrapolated delta for both and
+// divides by the range only when isRate, so multiplying it back is the
+// identity, not an approximation. The grid parameters are rendered as
+// literals, not bound args — they are aggregate-function parameters — and
+// the experimental gate rides as a SETTINGS clause on the statement itself
+// so telemetrystore hooks cannot clobber it.
+//
+// The join annotates each series with its group key: toJSONString of the
+// sorted [label, value] pairs the unit projects, extracted from the stored
+// labels JSON. by keeps the listed labels, without excludes them plus
+// __name__, no aggregation keeps everything minus __name__ unless the unit
+// keeps its name — the engine's name-dropping rules. Correct as a grouping
+// key because the pairs are sorted and empty values are filtered: key
+// equality is then exactly label-set equality on the projection —
+// Prometheus treats an empty label value as the label being absent, and
+// stored attribute JSON can carry empties that must not split groups — and
+// the same canonical string parses back into the output label set
+// (labelsFromGroupKey).
+//
+// The outer GROUP BY is the spatial aggregation: sum/min/max/avg/count
+// by/without become the -ForEach combinators. Element-wise aggregation over
+// grid arrays is the engine's per-t_i aggregation, because slot i of every
+// input array refers to the same t_i; the combinators skip NULLs, which is
+// the engine aggregating only the series present at t_i, and an index where
+// every series is absent stays NULL. Two edges need explicit handling:
+// countForEach wraps in a mapping of 0 back to NULL, because a count over
+// an all-absent index is an absent point, not 0; and a unit without
+// aggregation still passes through maxForEach — the identity for the common
+// one-fingerprint group, and a deterministic NULL-skipping merge when a
+// regex __name__ selector collapses distinct metrics onto one projected
+// label set. One caveat is inherent: summation order over series differs
+// from the engine's, so spatial aggregates can differ in the last ULP —
+// float addition is not associative; no ordering reproduces the engine's
+// bit-exactly from inside a GROUP BY.
+//
+// # Instant selectors: staleness needs two aggregates
+//
+// unitInstant uses window = lookback and must reproduce the shadowing rule:
+// the point is absent when the latest in-window sample is a stale marker.
+// timeSeriesLastToGrid alone cannot express that — skipping stale rows in
+// WHERE would resurrect the older real sample the marker was written to
+// bury. So stale rows stay in the scan for this kind only, and the grid
+// expression compares three aggregates per slot:
+//
+//	arrayMap((tall, tok, vok) -> if(tall IS NULL OR tok IS NULL OR tall != tok, NULL, vok),
+//	         timeSeriesLastToGrid(...)(ts, toFloat64(unix_milli)),                           -- last sample overall
+//	         timeSeriesLastToGridIf(...)(ts, toFloat64(unix_milli), bitAnd(flags, 1) = 0),   -- last non-stale, its timestamp
+//	         timeSeriesLastToGridIf(...)(ts, value, bitAnd(flags, 1) = 0))                   -- last non-stale, its value
+//
+// Correct by cases on a slot's window. No samples at all: both timestamp
+// aggregates are NULL, the slot is NULL — absent, as the engine says. Latest
+// sample non-stale: it is the latest overall and the latest non-stale, the
+// timestamps agree, the slot takes its value — the engine's pick. Latest
+// sample stale: the last-overall timestamp is the marker's, the
+// last-non-stale timestamp is older (or NULL when only markers are in
+// window), they disagree, the slot is NULL — the marker shadows, exactly
+// the engine's rule. Timestamps are unique per series (ingest dedups), so
+// timestamp equality identifies "the same sample" without ambiguity. The
+// -If combinator's applicability to these experimental aggregates was
+// probed before being trusted, not assumed.
+//
+// # Windowed *_over_time: fan-out instead of a grid function
+//
+// avg/min/max/sum/count _over_time aggregate every raw sample in the window,
+// and no timeSeries*ToGrid function computes them. (last_over_time is the
+// exception: the last sample of a range vector — stale markers excluded from
+// range vectors by PromQL, excluded here in WHERE — is exactly
+// timeSeriesLastToGrid.) Instead, each sample is fanned out to every grid
+// index whose window contains it:
+//
+//	ARRAY JOIN range(toUInt64(greatest(0, intDiv(unix_milli - <start> + <step> - 1, <step>))),
+//	                 toUInt64(least(<lastIdx>, intDiv(unix_milli + <range> - 1 - <start>, <step>)) + 1)) AS k
+//
+// Correct because the bounds solve the window condition for k. A sample at
+// ts contributes to slot k iff t_k - range < ts <= t_k. The right side
+// gives t_k >= ts, so the first index is ceil((ts - start)/step) — a sample
+// at exactly t_k belongs to k, the window is right-closed. The left side
+// gives t_k < ts + range, and with millisecond-integer timestamps that is
+// t_k <= ts + range - 1, so the last index is
+// floor((ts + range - 1 - start)/step) — a sample at exactly t_k - range is
+// excluded, the window is left-open. Clamped to the grid, the fan-out
+// therefore lands each sample in exactly the slots whose windows contain
+// it, and GROUP BY (fingerprint, k) with the plain aggregate (avg(value),
+// min(value), ...) computes per slot over precisely the engine's sample
+// multiset — the same numbers, since avg/min/max/sum/count are
+// order-insensitive on a given multiset (sum/avg up to summation order, the
+// float caveat above). A second level assembles the positional array with
+// groupArray + indexOf, mapping missing indices to NULL — groupArrayInsertAt
+// would coerce NULL defaults to 0, which is a value, not absence. The
+// group-key join happens at the initiator here, over rows already reduced
+// to per-(series, index); see the sharding section for why that costs
+// nothing.
+//
+// # Scalar ops, full plans, hybrid plans
+//
+// The scalar-op pipeline applies in Go to the returned arrays
+// (applyScalarOps), slot by slot: arithmetic operators compute, comparisons
+// filter (the slot keeps the vector-side value or becomes NULL) or return
+// 0/1 under bool. Correct trivially: it is the same float64 operation the
+// engine would apply to the same slot value, in the same operator order the
+// AST dictates — running it in Go instead of another SQL layer changes
+// where, not what.
+//
+// A full plan's arrays map straight to the result matrix. A hybrid plan
+// materializes each unit's arrays as synthetic series under its
+// __signoz_transpiled_N__ name and evaluates the rewritten expression over
+// a storage that serves synthetic names from memory and everything else
+// live. Substitution is sound because a unit's output is a plain instant
+// vector to the engine — same values at same timestamps under a different
+// name, and the name cannot matter: plans that group by or match on
+// __name__ were refused at classification, and name-keeping units are never
+// substituted. One subtlety makes it exact: stale markers are written at
+// absent grid points, because the engine's lookback would otherwise
+// resurrect a point from up to lookback earlier — the marker encodes
+// "absent here" the way the engine itself encodes it. Units evaluate
+// concurrently; each is one series lookup plus one grid statement. A step
+// of 0 is an instant query: a single evaluation at end.
+//
+// # Series lookup
+//
+// Both paths resolve matchers the same way, once per selector
+// (selectSeries): __name__ matchers translate to the metric_name column —
+// all four matcher types; the v1 client silently returned nothing for regex
+// metric names — and every other matcher to a JSONExtractString condition on
+// the labels column (applySeriesConditions). Regexes are anchored before
+// they reach match(): PromQL matchers match the whole value, ClickHouse
+// match() searches for a substring, and without anchoring =~"api" would
+// also select "x-api-y". An equality matcher against "" matches series
+// without the label, mirroring PromQL, because JSONExtractString returns ""
+// for missing keys. The series tables hold one row per (fingerprint, bucket)
+// at 1h/6h/1d/1w granularities; timeSeriesTableFor picks the table whose
+// bucket fits the window and rounds the window start down to the bucket
+// boundary. The resulting label sets drop what v1 leaked into results: the
+// synthetic fingerprint label (it would take part in without() grouping and
+// vector matching) and empty-valued labels. MaxFetchedSeries fails the
+// lookup with a typed invalid-input error past the ceiling — v1's behavior
+// for an oversized selector was to buffer everything and OOM, and a 4xx the
+// user can narrow beats a dead process serving nobody.
+//
+// # The engine path
+//
+// Queries that do not transpile run in the stock engine over this package's
+// storage.Querier, which is still not the v1 path. Samples are fetched per
+// selector using the engine's per-selector hints, not the query-wide union
+// window, so foo / foo offset 1d reads two narrow windows instead of the
+// widest one twice. Instant selectors of subquery-free queries fetch only
+// the last sample per step bucket (lastSamplePerStep): buckets anchor at the
+// selector's first evaluation timestamp — recovered from the hints as
+// hints.Start + lookback - 1ms, the inverse of how the engine derives
+// hints.Start — so bucket boundaries coincide with evaluation timestamps and
+// a non-final sample of a bucket can never be the latest sample in
+// (t - lookback, t] for any grid t. Real timestamps are preserved, so the
+// engine's own lookback and staleness handling stay exact. Range selectors
+// always fetch raw — every sample feeds the range function — and the
+// subquery-free proof travels in the context as prometheus.QueryTraits,
+// because subquery selectors evaluate at the subquery's step while the
+// hints carry the top-level step. Row assembly counts rows against
+// MaxFetchedSamples while scanning, keeps the first of consecutive equal
+// timestamps, maps stale flags to the engine's StaleNaN, and merges series
+// with identical label sets (sortAndMerge) — the engine assumes storages
+// never emit duplicates. A {job="rawsql", query="..."} selector bypasses all
+// of this and runs the query matcher's value verbatim.
+//
+// # Sharding
+//
+// samples_v4 and time_series_v4 (and all their rollups) shard on the same
+// key — cityHash64(env, temporality, metric_name, fingerprint) — so a
+// series' samples and catalog rows live on the same shard. The transpiled
+// statement above exploits that: the distributed samples table at the
+// top-level FROM makes ClickHouse rewrite the whole inner query per shard,
+// where the join against the shard-local series table and the per-series
+// grid aggregation run next to the data; the initiator only merges
+// aggregate states and applies the spatial -ForEach step. Same layout as
+// the telemetrymetrics statement builder. Fingerprint filters follow suit:
+// matched sets inline as sorted literals up to inlineFingerprintsLimit
+// (literals engage the samples primary key; sorting keeps statements
+// deterministic), beyond it the group-key join alone restricts — a
+// semi-join on the same predicates would only rescan the series table —
+// except the windowed *_over_time fan-out, which has no join and keeps a
+// shard-local IN subquery rather than expand every series of the metric.
+// The engine path's over-limit filter is the same shard-local subquery, not
+// a GLOBAL broadcast of the matched set. The temporality filter on every
+// samples statement is a semantic no-op — the matched fingerprints already
+// come from those temporalities — that engages the leading samples
+// primary-key column. Delta-temporality series stay invisible to PromQL
+// here exactly as they are in v1: the rollout gate is parity with v1, and
+// making Delta visible is its own change with its own semantics to design —
+// a Delta stream fed to rate() as-if-cumulative would be wrong, not just
+// new.
+//
+// # Observability
+//
+// Every statement carries a log_comment with
+// code.namespace=clickhouse-prometheus-v2 and code.function.name naming the
+// call site (selectSeries, selectSamples, transpiledUnit, LabelValues,
+// LabelNames), so this provider's work is attributable in system.query_log
+// without guessing from query text.
