0.1.0 (2026-08-21)

Initial release.

  • Enact.run/3, Enact.dry_run/3, Enact.subject/3, and Enact.authorized/3 — the load → authorize → cast → validate → resolve → execute → after_commit pipeline with actor enforcement, the closed error taxonomy, and telemetry events. subject/3 returns the loaded record; authorized/3 returns :ok. Both are load + authorize only (locator params, no body). Atom-keyed params are stringified at the boundary (values untouched; atom+string collision at the same level raises)
  • Enact.Action and Enact.InputSchema behaviours; Enact.Actor protocol. authorize/1 is required (an open write is a written true); optional callbacks are declared via @optional_callbacks
  • Usage rules: params are the invocation payload; persistable fields are not passed via assigns:
  • Phoenix guide: application callers use context one-liners that forward to Enact.run/3 / dry_run/3 / subject/3 / authorized/3
  • Enact.Delegates — opt-in use that generates those one-liners (create_contact/2, create_contact_dry_run/2, create_contact_subject/2, create_contact_authorized/2) from actions: [CreateContact, ...]
  • Presence-based change detection: Enact.provided?/2 and Enact.updates/2
  • Enact.Resolve — scalar and batch reference resolution with enumeration-resistant error rendering
  • Enact.Validations (check/2, unique/3) and Enact.Guardrails (mechanical input-schema invariants)
  • Enact.Preview with a confirmation digest binding action, mode, locator params (params keys not in the input schema), and the canonical updates map; subject is the loaded record for old → new diffs
  • Enact.InputSchema.cast_input/4 — casting with JSON API empty-string semantics derived from field types (keep_empty_strings: option)
  • partial_embeds/1 input-schema manifest — partial-object PATCH semantics for declared embeds_one fields, with presence-faithful updates, previews, and confirmation digests
  • Enact.merged/4 — the result-state view of a partial embed, shared by merged-result validation rules and the execute-side merge
  • Enact.Test helpers for host-app suites, including the assert_rejects_empty_strings/3 behavioral probe
