#7219 a0743f2 Thanks @tim-smart! - Add SQL, HttpApi testing, and CLI schema examples to the published AI documentation.
#7241 17892e7 Thanks @tim-smart! - Use Context mapUnsafe in less call sites

#7216 f21f9c9 Thanks @tim-smart! - Add a HttpStatus module to effect/unstable/http that centralizes the mapping from HTTP status literal names to numeric codes and exports HttpStatus.fromLiteral. HttpApiSchema.status now consumes the new module.
#6829 18270dd Thanks @lloydrichards! - MCP servers now support the 2024-11-05 and 2025-03-26 RPC revisions through version-specific protocol adapters.
#7218 26db404 Thanks @tim-smart! - Run SQL PersistedQueue table creation through versioned migrations so future schema changes can be applied safely.
#7210 2670398 Thanks @tim-smart! - Preserve nanosecond precision when adjusting TestClock with large durations.
#7205 3702bed Thanks @tim-smart! - Remove the kubernetes-types dependency by vendoring the Kubernetes Pod declarations used by the cluster helpers and exporting them from effect/unstable/cluster/K8sTypes.
#7236 ccae60e Thanks @roninjin10! - Propagate a failed BEGIN or SAVEPOINT from SqlClient.withTransaction as a typed SqlError.

makeWithTransaction wrapped the begin step together with the transaction body, so a
failed BEGIN took the rollback branch. No transaction was active at that point, the
ROLLBACK failed, and its Effect.orDie wrapper replaced the original typed error with a
defect (cannot rollback - no transaction is active). Callers could no longer classify the
failure as retryable. The path became reachable when the sqlite client started using
BEGIN IMMEDIATE, which acquires a write lock and can fail with SQLITE_BUSY.

Commit and rollback now run only after begin or savepoint succeeds. A failed begin or
savepoint fails with its original SqlError, leaves the wrapped effect unexecuted, and
still closes the acquired connection scope.
#7206 6ff5396 Thanks @tim-smart! - Bound cluster runner entity residency and storage reads.

ShardingConfig gains two knobs:
- maxResidentEntities (default 10_000): the maximum number of entities
  that can be resident on a runner at the same time. At the cap, the storage
  read loop stops admitting messages for new entity addresses (they stay in
  storage until a slot frees up) and volatile sends to new addresses fail with
  MailboxFull. Persisted sends still succeed. "unbounded" restores the
  previous behaviour and can only be set programmatically.
- unprocessedMessageBatchSize (default 1024): the maximum number of
  unprocessed messages read from storage in a single poll.
MessageStorage.unprocessedMessages accepts an optional
{ limit, addresses } argument, and only claims the messages it actually
returns. The memory implementation now applies the same ten-minute claim
window as SQL, so bounded reads advance past in-flight requests; resetting an
address or shard makes its claimed messages immediately eligible again.

The encoded driver contract replaces Encoded.resetAddress with the batched
Encoded.resetAddresses operation. SqlMessageStorage.makeEncoded constructs
the SQL encoded driver directly for custom storage composition.

ClusterWorkflowEngine entities (workflows and the durable clock) now use a
fixed ten-second idle time, so completed and suspended executions release their
entity slots quickly. Their state is durable, so an evicted execution is
rebuilt from storage when its next message arrives.

#7180 c82c532 Thanks @gcanti! - Prioritize redacted representations in formatters and normalize text logger levels to uppercase.
#7193 22b579f Thanks @kitlangton! - Fix Deferred.await dying with a TypeError when a waiter is interrupted after the Deferred has been completed.
#7179 3e19539 Thanks @tim-smart! - Fix DurableDeferred.raceAll so a completed deferred can wake an active workflow without changing success-biased race semantics
#7189 08a3c74 Thanks @gcanti! - Fix HttpApi query decoding for array parameters with a single value.
#6550 eb0bae0 Thanks @xianjianlf2! - Return fresh OpenAPI specs from cached OpenApi.fromApi calls.
#7188 97b544d Thanks @gcanti! - Mark the internal ~sentinels Schema annotation as @internal so release declaration stripping removes it together with SchemaAST.Sentinel. This keeps the published declarations self-consistent for consumers that type-check dependencies with skipLibCheck: false.
#7158 4f6d131 Thanks @k3dom! - Improve Union candidate selection: a nested union member is dispatched by the sentinels common to all its members, and candidates whose sentinel the input contradicts are excluded.
#7178 fad4b7c Thanks @tim-smart! - Use Promise microtasks for synchronous Scheduler dispatch.
#7181 accf447 Thanks @gcanti! - Move SchemaError into the Schema module and remove the standalone SchemaError module.
#7195 31b27e4 Thanks @tim-smart! - Ensure discarded non-persisted cluster messages complete without waiting for the entity reply.
#7191 8458951 Thanks @Digifox03! - Fix HttpRouter.Middleware.layer to provide request error services for errors declared in handles, and expose global
middleware errors from HttpRouter.toHttpEffect.

Patch Changes

#7156 596f3f9 Thanks @tim-smart! - Terminate active multipart file streams when a parser limit is exceeded or the body ends unexpectedly, so file parts fail instead of hanging.
#7153 9611ed4 Thanks @rajanpanth! - Fix Duration's Hash.symbol implementation to hash a canonical nanoseconds form instead of the raw internal Millis/Nanos representation. Two durations that Duration.equals/Equal.equals consider equal (e.g. Duration.seconds(5) and Duration.nanos(5_000_000_000n)) previously hashed differently, violating the Hash/Equal contract and silently breaking HashSet/HashMap lookups keyed by Duration.
#7166 8b91605 Thanks @CDVolvik! - Import migrations through a file URL in Migrator.fromFileSystem, so absolute Windows paths are accepted by the ESM loader.

Previously the directory and file name were passed to import as a plain path. On Windows that produced a specifier such as D:\migrations\1_init.ts, which the ESM loader rejects with Only URLs with a scheme in: file, data, and node are supported.

fromFileSystem now resolves the specifier through the Path service, so its type widens from Loader<FileSystem> to Loader<FileSystem | Path>. Callers that already provide an aggregate platform layer such as NodeServices.layer are unaffected; callers that provide FileSystem on its own now also need a Path layer, and on Windows it must be a platform-aware one rather than the POSIX Path.layer.
#7157 d901928 Thanks @tim-smart! - Add Channel.mkUint8Array and reuse it from Stream and multipart file collection. This also fixes quadratic buffering in File.contentEffect, improving collection of a 16 MiB chunked upload by approximately 90x.
#7149 b32bdef Thanks @gcanti! - Require explicit handling for regular expression pattern constraints translated from JSON Schema documents, with modes to apply trusted patterns or ignore their constraints.

#7114 6310a8c Thanks @fubhy! - Report buffered worker send failures as WorkerError values.
#7117 c2071b1 Thanks @fubhy! - Make TxQueue.shutdown safe to call after a queue has already been interrupted.

#7105 a1d4057 Thanks @tim-smart! - Add ConfigProvider.fromEnvRecord for building a provider from an explicit environment record.
#7111 abf77b0 Thanks @fubhy! - Preserve input fiber error types in Fiber.joinAll.
#7134 6c60375 Thanks @marbemac! - Fix cluster shutdown hangs by failing abandoned non-discard requests and stream chunk acknowledgements with EntityNotAssignedToRunner, including persisted requests sent after runner unregistration. This adds EntityNotAssignedToRunner to the typed error channel of entity clients and request-only EntityProxy RPC/HTTP endpoints; discard endpoints remain unchanged.
#7107 22f4897 Thanks @fubhy! - Preserve FormData bodies when converting client requests through HttpServerRequest.
#7120 615d1d5 Thanks @fubhy! - Fix SqlResolver.findById failing to complete duplicate requests when id encoding fails, which surfaced as a RequestResolver did not complete request defect instead of the underlying SchemaError.
#7131 3a86757 Thanks @fubhy! - Ignore MCP cancellation notifications for unknown request identifiers.
#7104 f4a9762 Thanks @gcanti! - Add Function.memoizeIdempotent and use it to avoid reprocessing canonical Schema ASTs, including optional and mutable property modifiers. Cache Config schema cursor AST compilation.
#7144 0bcf6ed Thanks @fubhy! - Stop multipart parsing after part count, part size, or field size limits are exceeded.
#7121 ba9cb63 Thanks @fubhy! - Prevent execution-plan event observer defects from changing attempt outcomes or leaving attempt events unpaired.
#7147 42c810d Thanks @tim-smart! - Release worker pool entries when an RPC worker's receive loop fails.
#7148 1416ccd Thanks @gcanti! - Consolidate schema arbitrary derivation into Schema.toArbitrary, which now returns a Schema.Arbitrary factory that accepts the fast-check module. Remove Schema.toArbitraryLazy and arbitrary derivation reports.
#7109 08d0d39 Thanks @fubhy! - Fix RcRef leaking resources acquired before a failed acquisition.
#7146 548908a Thanks @gcanti! - Improve Schema representation identity, anonymous-reference eligibility, and JSON Schema alias finalization.
#6862 4b3460d Thanks @fubhy! - Ensure ScopedRef.set releases a replacement when the previous value's finalizer defects.
#7060 d170596 Thanks @fubhy! - Preserve maxItems semantics when importing JSON Schema prefixItems.
#7116 aea89d0 Thanks @fubhy! - Keep span end times at zero when tracer timing is disabled.
#7124 deed5fb Thanks @fubhy! - Use a distinct AES-GCM initialization vector for each encrypted event log entry. EventLogEncryption.encrypt now returns each IV with its ciphertext, and encrypted event log clients and servers must be upgraded together because the WriteEntries wire shape changed.

#7087 0418564 Thanks @tim-smart! - Recognize tagged Config and RPC errors across duplicated effect package copies.
#6827 d334a85 Thanks @jaipaljadeja! - Add bounded 429 retries and custom response header names to HttpClient.withRateLimiter.
#7084 f0be855 Thanks @tim-smart! - Stop capturing definition-location stack frames in Context.Service.
#7090 b206fa5 Thanks @tim-smart! - Expose stdinIsTerminal and stdoutIsTerminal effects through the Stdio service.
#7093 b938c8a Thanks @gcanti! - Add the opt-in reportInput parse option for retaining rejected inputs in enumerable fields on value-bearing schema issues and including them in default formatted messages. Value-bearing issue constructors accept the rejected input and parse options directly, and Schema.Annotations.Issue now supports expected for default messages.

Schema issues no longer format implicitly through Issue#toString. Use SchemaIssue.makeFormatterDefault() when a human-readable message is needed. The throwing and Promise-based adapters in SchemaParser now use the generic message "Schema validation failed" and expose the structured SchemaIssue.Issue as the error cause; consumers that previously read the formatted error message should inspect and explicitly format that cause instead.

Schema.makeEffect now returns SchemaIssue.Issue failures instead of wrapping them in SchemaError, and Schema.withConstructorDefault accepts an Effect that fails with SchemaIssue.Issue. Fallible Optic operations return structured SchemaIssue.Issue failures, while schema failures from Schema.toIso and Schema.toDifferJsonPatch use the generic error message and preserve the issue in cause instead of formatting it internally.
#7097 8525f05 Thanks @tim-smart! - Add Cron.format for converting a Cron instance to a cron expression, with an option to include the seconds field.

#6934 1001bcc Thanks @tim-smart! - httpapi: add typed response headers across handlers, generated clients (including HttpApiTest), streaming responses, and OpenAPI with HttpApiSchema.WithHeaders. Add HttpApiSchema.encodeToWithHeaders for folding response headers into domain types such as error classes. Explicit content-type and content-length values applied with HttpServerResponse.setHeader or setHeaders now override body-derived values.

#6983 1434eec Thanks @fubhy! - Apply byte range and chunk size options to default Web file responses.
#7071 a5278b1 Thanks @fubhy! - Fix MCP sampling metadata optionality and validate it as an object.
#6946 6af04a5 Thanks @fubhy! - Defer memoized Layer state installation until Effect execution.
#6943 cb6c837 Thanks @fubhy! - Reject zero execution attempts in ExecutionPlan steps.
#7026 d44cead Thanks @tim-smart! - Add execution-plan lifecycle events via an optional onEvent handler on Effect.withExecutionPlan and Stream.withExecutionPlan.

The handler receives an ExecutionPlan.Event, a tagged union of AttemptStart, AttemptSuccess, and AttemptFailure, allowing attempt outcomes to be observed from outside the effect for logging and metrics:
```
import { Effect } from "effect"

Effect.withExecutionPlan(program, plan, {
  onEvent: (event) => Effect.log("execution plan event", event)
})
```
Every AttemptStart is followed by exactly one terminal event. AttemptFailure carries the full failure Cause, so defects and interruption are reported as well as expected errors, and terminal events run like finalizers so they are emitted even when the attempt is interrupted. Event numbering matches ExecutionPlan.CurrentMetadata: attempt is cumulative across steps, while stepAttempt is 1-based within the current step.
#7077 88c7632 Thanks @tim-smart! - Rename Schedule.andThen and Schedule.andThenResult to Schedule.concat and Schedule.concatResult.
#6975 abcbb2a Thanks @fubhy! - Encode SSE events with empty data as dispatchable events.

#7032 936b135 Thanks @marbemac! - Fix a @effect/cluster shutdown deadlock on single-runner topologies (e.g. single-node deployments and TestRunner), where Sharding.sendOutgoing retried EntityNotAssignedToRunner forever during teardown.

#7041 5f3fb81 Thanks @fubhy! - End runner streams after emitting their terminal replies.

#7020 17f0b91 Thanks @gcanti! - Fix Schema.make to preserve existing nested Schema.Class instances, including in array fields, while recursively constructing plain class inputs provided at runtime inside unions. Constructor defaults remain scoped to structural field and element occurrences, with SchemaAST.Context.constructorDefault representing the single default link for each occurrence.

Optimize Function.memoize to use a single WeakMap lookup for cached values. Its callback no longer accepts undefined as a return type because undefined represents a cache miss.

The performance of the two array paths can be reproduced by saving the following program as
scratchpad/schema-make-6890-benchmark.ts and running node scratchpad/schema-make-6890-benchmark.ts from the repository
root:

import { Schema } from "effect"
import { performance } from "node:perf_hooks"

class Row extends Schema.Class<Row>("Row")({ value: Schema.String }) {}
class DirectTable extends Schema.Class<DirectTable>("DirectTable")({ rows: Schema.Array(Row) }) {}
class UnionTable extends Schema.Class<UnionTable>("UnionTable")({ rows: Schema.Array(Schema.Union([Row])) }) {}

const rows = Array.from({ length: 30_000 }, (_, value) => Row.make({ value: String(value) }))

function benchmark(label: string, make: () => { readonly rows: ReadonlyArray<Row> }) {
  const samples: Array<number> = []
  for (let i = 0; i < 6; i++) {
    const start = performance.now()
    const result = make()
    samples.push(performance.now() - start)
    if (result.rows[0] !== rows[0] || result.rows.at(-1) !== rows.at(-1)) {
      throw new Error(`${label} did not preserve Row identity`)
    }
  }
  console.log(`${label}: ${samples.slice(1).map((n) => n.toFixed(3)).join(", ")} ms`)
}

benchmark("Array(Class)", () => DirectTable.make({ rows }))
benchmark("Array(Union([Class]))", () => UnionTable.make({ rows }))

Representative local results on Node 24.12.0 (six runs, with the first discarded):

Array(Class): 0.639, 0.498, 0.447, 0.448, 0.451 ms
Array(Union([Class])): 3.141, 2.195, 2.126, 2.108, 2.057 ms
