Unreleased
v0.1.1 — 2026-08-08
Adoption polish: a runnable Livebook walkthrough, richer Igniter installer, and adoption docs. No contract change; safe minor bump from v0.1.0.
- Add a runnable Livebook walkthrough
covering idempotency (fresh, replay, fingerprint conflict) and one-time nonces (spend, reuse
rejection) end-to-end against a real PostgreSQL, plus the value-free telemetry surface. The
walkthrough is regression-pinned by
test/ash_onetime/livebook_walkthrough_test.exs. - Extend the Igniter installer with a repeatable
--resource MyApp.MyResourceflag that wiresAshOnetime.Resourceinto a resource and scaffolds a starteronetimeblock. Non-resource targets and missing modules are rejected loudly instead of silently no-op'ing. - Add adoption docs: Recipes, Telemetry, Upgrading, and FAQ. Add a README "When to use this vs. hand-rolled idempotency" section and a "Try it" livebook pointer.
- Reorder Getting started to lead with the consumer quickstart (install → protect → handle the result); move the test-DB harness to CONTRIBUTING. Fix the stale "not published yet" line (the package is live on Hex).
v0.1.0 — 2026-08-08
- Breaking (DSL): collapse the dual
limitssurface into a singleprotect-level vocabulary. Response-size limits can no longer be declared on theresponseentity (response ..., limits: [...]); declare them onprotectinstead. Theprotect limits:option now accepts the full 11-key union vocabulary:max_key_bytes,max_token_bytes,max_scope_components,max_fingerprint_bytes,verifier_timeout_ms,max_cache_entry_bytes(key/verification/cache paths), andmax_response_bytes,max_response_depth,max_response_nodes,max_response_entries,max_response_scalar_bytes(response payload). All keys are validated at compile time. To migrate, move anyresponse ..., limits: [max_response_*: ...]keys ontoprotect ..., limits: [...]. - Make
AshOnetime.Errora Splode error of class:invalidso Ash recognizes it and preserves the typed:codethrough the action pipeline. Before, a protected-action failure was wrapped asAsh.Error.Unknown.UnknownErrorand the code (e.g.:nonce_already_used,:key_reused_with_different_request) was lost before it could reach the caller. AddAshOnetime.Error.code/1to recover the code from a leaf or class wrapper. Seedocumentation/errors.mdfor the code→HTTP table. - Add a caller-visible replayed-vs-fresh signal. After
Ash.create/2/Ash.run_action/2returns,AshOnetime.replayed?/1reports whether the result was a stored replay (true), a fresh execution (false), or carries no signal (nil— untracked execution, primitive-return action, or unprotected). The signal rides__metadata__[:ash_onetime]for tracked admission classes;:untrackedis deliberately not stamped to preserve untracked transparency. Seedocumentation/replay.md. - Broaden the Ash dependency requirement from
~> 3.29.0(only 3.29.x) to>= 3.29.3 and < 4.0.0, so the package installs across the whole Ash 3.x line. The floor is 3.29.3, not 3.29.0: EEF-CVE-2026-55736 (private action arguments settable by user input) affects Ash 3.29.0–3.29.2 and is fixed in 3.29.3. - Add a CI compatibility matrix (
.github/workflows/ci.yml), configured to run the full gate battery — includingmix hex.audit— against the 3.29.3 floor, each intermediate minor, and a floatinglatestAsh 3.x cell on every push and pull request once the repository is pushed to a GitHub remote. - Establish the standalone Mix package, PostgreSQL 18 test harness, package boundary checks, accepted architecture decision, and project documentation.
- Add the per-action Spark resource DSL, normalized introspection, precompile rejection boundary, fail-closed runtime stubs, compile-fixture battery, and mutation proofs.
- Add PostgreSQL-authoritative idempotency and one-time nonce admission with exact operation, scope, key, fingerprint, transaction, and failure-direction invariants.
- Add transactional CRUD and generic-action execution, classified typed response persistence,
digest-bound replay, and replay-safe lifecycle enforcement. The response contract digest binds
the codec options, so stored bytes cannot be reinterpreted under changed options; replayed
results carry the same
selected/tenantmetadata as a first execution. - Enforce the configurable
max_scope_components,max_fingerprint_bytes, andmax_response_byteslimit overrides at their declared values, not only their package ceilings. - Add bounded canonical encoding, HMAC-SHA-256 and Ed25519 signing, trusted verification facts, self-identifying tokens, and inclusive nonce windows.
- Add committed external-effect recovery points, stable peer operation keys, conservative ambiguous-outcome handling, and crash recovery.
- Add unpartitioned and operation-hash-partitioned claim layouts, date-partitioned response payloads, strict bounded cleanup, deletion guards, the prune task, and optional Oban cleanup.
- Add PostgreSQL-gated cache degradation, optional Plug header extraction, closed value-free telemetry, deterministic Igniter installation, and migration generation.
- Add system, architecture, mutation, documentation, exact Hex archive, unpacked consumer, and dependency audit release gates, run on the pinned Elixir 1.20.2 / Erlang/OTP 29 runtime.
