build(deps): bump @mastra/core from 1.52.1 to 1.63.0

[dependabot]

Bumps @mastra/core from 1.52.1 to 1.63.0.

Release notes

Sourced from @​mastra/core's releases.

August 26, 2026

Highlights

Trace-correlated logging via the new logger adapter contract

A new AdaptableLogger contract in @mastra/core/logger standardizes trace correlation by injecting trace_id/span_id into native log records during traced operations, and deriving observability LogEvents from the same record. Mastra now supports loggerOptions to control correlation and log export, and the legacy dual-write wrapper path is deprecated.

First-class Pino integration with trace context in every transport

@mastra/loggers’ PinoLogger now implements the adapter contract, so trace fields are added via a pino mixin to stdout, files, and custom transports—while preserving user mixin fields. This aligns native application logs with Mastra observability without separate logging pipelines.

More reliable trace/log linking for non-exported spans (no more “Span not found”)

Across @mastra/core and @mastra/observability, logs/metrics emitted inside internal or excluded spans now link to the nearest ancestor span that actually reaches exporters, and omit spanId when none exists. This fixes broken click-through from Studio and ensures stdout correlation matches stored observability records.

Deployment readiness improvements: worker health gating

@mastra/deployer now ships a dedicated worker entry in standard build artifacts, and the worker runtime exposes a /health endpoint that returns 503 during startup and 200 once workers are initialized. This enables deployment platforms to block rollouts until workers are actually ready.

Scheduler + resume robustness fixes (fewer restarts, fewer duplicate runs)

Workers now discover and run schedules created after startup without requiring a restart. Tool/background-task resuming is also hardened (supports falsy resume payloads like false/0/""), preventing suspended background tasks from accidentally starting a second run and ensuring replayed tool-call chunks are preserved for reloading clients.

Breaking Changes

• @mastra/playground-ui DataList API cleanup: removed variant="lined", flushLeft/flushRight, per-cell height, and DataList.MonoCell (use DataList.TextCell font="mono" instead).

Changelog

@​mastra/core@1.63.0

Minor Changes

• Added a logger adapter contract (AdaptableLogger in @mastra/core/logger) for trace-correlated log output. Loggers implementing the adapter inject trace_id and span_id into their native log records during traced operations, and the observability LogEvent is derived from that same record. The built-in ConsoleLogger implements the contract. A new loggerOptions config on Mastra controls the behavior: (#21753)

  import { Mastra } from '@mastra/core/mastra';
  export const mastra = new Mastra({
  loggerOptions: {
  correlation: true, // inject trace_id/span_id into native output (default: true)
  export: true, // forward log records to observability storage (default: true)
  },
  });

  Custom IMastraLogger implementations without adapter support continue to work through the existing dual-write wrapper, which is now deprecated and will be removed in the next major version.

Patch Changes

• Update provider registry and model documentation with latest models and providers (7176362)

• Fixed worker processes to discover and run schedules created after startup without requiring a restart or explicit scheduler configuration. (#22420)

• Fixed output stream processor traces remaining open when streams close or are canceled before a finish chunk. (#22397)

• Added an optional getExportedSpanId() method to the Span interface. It returns the span's own id when the span reaches exporters, and the nearest exportable ancestor's id when it does not. (#22286)
