All notable changes to this package are documented here. Releases are managed from conventional commits by the repository release workflow.

1.0.0

• Add the identity surface: slugify (NFKD, combining-mark removal, ASCII kebab, total and idempotent), namespacedKey (Result<String>, naming the offending NamespacedKeyField on failure), and fuzzyIncludes.
• Add the C0 §3 layered-configuration mechanics: JsonObject, deepClone, deepMerge, deepMergeAll, canonicalConfigKey, configKeysMatch, coerceEnvironmentScalar, and environmentToNestedMap. Key matching is case- and separator-insensitive (including the environment prefix), the base layer's key spelling wins, __ splits paths, all-digit components build lists, blank values mean UNSET, and neither JSON nor comma-separated strings are ever decoded into collections.
• Add deterministic config projection: isJsonObject, stableConfig, and stableConfigObject, sorting keys at every depth while preserving list order, and reporting circular input as record_unprojectable instead of recursing.
• Add the C0 §1 temporal wire forms: WireDate, WireTime, IsoDuration, and IanaTimezone value types with Result-returning parse/of members; formatRfc3339Utc; the STRICT parseRfc3339Utc (only the Z designator, so one canonical spelling exists); the normalizeRfc3339ToUtc boundary ingress for offset-carrying instants; and the WireCodec facade.
• Validate timezone identifiers by exact membership in a vendored, digest-pinned official IANA release (2026b, 598 identifiers) rather than a lexical shape check or host /usr/share/zoneinfo data, so the answer is reproducible.
• Export the shared, version-pinned C0 §1 temporal contract as the c0_temporal.dart sub-library, so every Diene Dart package drives its temporal conformance from one c0TemporalContract value instead of restating cases.
• Add Vfs-seam helpers over the published diene_interfaces interface type: readVfsText, writeVfsText, readOptionalVfsText, ConfigLayer, and loadConfigLayers. The package imports neither dart:io nor Flutter, so it runs on the VM, on the web, and in Flutter, and a seam failure is propagated unchanged with its own status and recoverable flag intact.
• Add sleep and mapWithConcurrency, the latter preserving input order, holding a real concurrency bound, and resolving to the lowest failing index so the outcome never depends on completion order.
• Report every expected failure as a Result value carrying the canonical RFC 9457 Problem from diene_problems, with the type URI minted only by the single C0 §2 builder (UtilName, UtilErrorCode, utilProblem, utilFailure, invalidUtilInput, invalidWireFormat).
• Ship no test_helper.dart: every member is a pure function or a pass-through over an injected seam, so there is nothing to fake and no assertion a consumer would repeat. The shipped diene-core-utils-usage skill carries the meta convention and explains how to add one should that change.
