Minor Changes

• fd54ac78: Persist alert evaluation errors (query errors, timeouts, webhook failures) as ERROR-state AlertHistory records instead of only a latest-only snapshot, upserted per evaluation window so retries collapse into a single row. Query timeouts are classified separately (QUERY_TIMEOUT, including timeouts wrapped by the ClickHouse query client) with an actionable message. ERROR rows are excluded from scheduling/backfill computations so failed windows are still retried and backfilled, and once a failed window recovers (via a same-window retry or a later tick's backfill) its stale ERROR row is removed. Evaluation analytics (query/webhook durations, backfilled buckets) are recorded on every history row.
• 05a3fd81: Add the AlertHistory evaluations read model and GET /alerts/:id/evaluations endpoint: per-window evaluation history scoped to a time range (clamped to the retention window) with per-group breakdown for group-by alerts, evaluation analytics fields, deduped error surfacing for ERROR-state windows, and cursor-based pagination that always advances across gaps. Adds read-side schema/type support for ERROR-state AlertHistory rows and evaluation analytics.
• 8508b6c7: Terraform export now emits team-scoped import ids (<team_id>/<resource_id>), so resources can be imported from a ClickStack deployment that backs more than one team. Each imported resource gains a team attribute, which the provider marks as forcing replacement — the generated file now says to keep it. The provider floor moves to >= 3.25.0, which drops server-only dashboard ids when importing, so the generated dashboard config no longer churns tile ids (and the tile alerts attached to them) on apply.
• 0ed72ddf: Add the metric formula expression model: a formulas entry on chart configs (letter-based series refs — A, B, C map to select positions) plus an arithmetic-only parser/validator (core/formula.ts) that produces a validated AST and structured validation errors (unknown series ref, empty expression, malformed syntax, invalid tokens). Groundwork for metric formulas like A / (A + B + C) * 100; no query rendering or UI changes yet.

Patch Changes

• b9430a62: feat: Add broadcast and variable settings to dashboard filters
• 546dd442: feat: Improve SQL Editor validations and autocomplete for variables
• cab98c7c: feat: Substitute dashboard variables in raw SQL tiles
• 018a6486: Clean up ESLint warnings and tighten lint enforcement. Resolved all no-unused-vars and @typescript-eslint/ban-ts-comment warnings (removing dead code and converting @ts-ignore to described @ts-expect-error), then promoted those rules to error in the api/app/common-utils/cli/hdx-eval configs, disabled the noisy @typescript-eslint/no-empty-function rule in app, and lowered each package's --max-warnings ceiling so the counts can't regress. Behavior is unchanged.
• 2d33b83b: Escape the Map subscript once in numeric and Bool field searches

The three equality branches for Bool and numeric value types escaped the column expression as an identifier even when it was already a rendered map subscript, so Measures.latency_ms:250 wrapped `Measures`['latency_ms'] in a second layer of backticks that ClickHouse reads as one identifier rather than a map lookup. Quoting the term worked around it for numeric maps; for Map(String, Bool) columns both spellings were affected.

• aedb514f: Multi-series metric charts now run as a single composed ClickHouse query instead of one query per series joined client-side. The per-series queries are combined via UNION ALL and pivoted back into one row per (group, time bucket) in SQL, including ratio charts (seriesReturnType: 'ratio') and both ratioMode variants, which previously divided the two result sets in the browser/node. Result shape, column naming (including same-alias __{index} disambiguation), gap semantics, and ratio semantics are unchanged; charts with many series render with fewer round trips, and "View SQL" for multi-series metric charts now shows the full query instead of only the first series.
