## 0.44.0

### Minor Changes

- [#2175](https://github.com/pyreon/pyreon/pull/2175) [`5ff4f21`](https://github.com/pyreon/pyreon/commit/5ff4f21ed13c2c194316fad4be9164fe4a06daf6) Thanks [@vitbokisch](https://github.com/vitbokisch)! - Animated leave + hard `toast.remove()`, and a fair three-way competitor benchmark.

  **Leave animation (fixes dead code + a doc over-claim).** `toast.dismiss(id?)` is now
  SOFT: it flips the toast to `state: 'exiting'`, plays the CSS leave transition
  (fade + collapse in place while siblings reflow smoothly), then hard-removes it
  after `LEAVE_DURATION` (200ms). Auto-dismiss and manual dismiss both animate out.
  `onDismiss` still fires immediately. Previously the `'exiting'` state was typed,
  styled, and read by the render layer but NOTHING ever set it — dismissal was
  instant and the documented exit animation never played. The store owns the leave
  timing (works headless); the fine-grained `<For by=id>` + `_toastMap` render path
  is unchanged (its `class` binding already reacts to `state==='exiting'`).

  **New `toast.remove(id?)`** — the HARD, instant, animation-free removal path (the
  exact `dismiss` (soft) / `remove` (hard) split react-hot-toast ships). Use it when
  you need a toast gone right now.

  **Behavior note (pre-1.0):** `toast.dismiss(id)` no longer removes from the store
  synchronously — the toast lingers as `exiting` for ~200ms while it animates. Code
  that read `_toasts()` immediately after `dismiss` should use `toast.remove(id)`
  (instant) or account for the leave delay.

  **Docs fixes:** README/docs/manifest/CLAUDE.md no longer claim `aria-live="polite"`
  (the a11y is type-aware `role="alert"`/`role="status"`), the phantom
  `ToastOptions.position` field is removed, and swipe-to-dismiss / collapsed-stacking
  / per-toast-position are documented as deliberate non-goals.

  **Benchmark:** a new `bench/toast-commit-bench.ts` adds react-hot-toast + sonner —
  a fresh-process create-throughput row (all three, fair) and mounted-Toaster
  create/update/dismiss→DOM-commit rows (@pyreon/toast vs react-hot-toast, where
  Pyreon's fine-grained patch beats React re-render ~20×). The headless
  `toast-bench.ts` now measures the hard `remove` path symmetrically.

### Minor Changes

- [#1728](https://github.com/pyreon/pyreon/pull/1728) [`14feb2e`](https://github.com/pyreon/pyreon/commit/14feb2e04b9f3b8867a474f9674c6f4ad6747bc4) Thanks [@vitbokisch](https://github.com/vitbokisch)! - feat(toast): description + icon, `<Toaster duration>`, type-aware a11y; drop dead per-toast `position`

  Feature-completeness + strict-typing pass:

  - **`description`** — an optional secondary line under the message (`toast('Uploaded', { description: '3 files · 1.2 MB' })`), updatable via `toast.update`.
  - **`icon`** — an optional leading icon (any VNode): `toast.success('Done', { icon: <CheckIcon /> })`.
  - **`<Toaster duration={…}>`** — the app-wide default auto-dismiss duration for toasts that don't set their own. This makes the previously-documented-but-unimplemented `duration` prop real (the manifest examples referenced it but it didn't exist — they now compile).
  - **Type-aware accessibility** — toasts now carry `role="alert"` (assertive) for `error`/`warning` and `role="status"` (polite) for `info`/`success`, instead of `role="alert"` on everything. The role implies its own `aria-live`, so the container no longer sets `aria-live="polite"` (which double-announced every toast).

  **Breaking:** `ToastOptions.position` is removed. It was typed but never honored (per-toast position did nothing); the container-level `<Toaster position>` is unchanged. Per-toast position would require a multi-stack Toaster and is deferred.

### Patch Changes

- [#1645](https://github.com/pyreon/pyreon/pull/1645) [`02b77ae`](https://github.com/pyreon/pyreon/commit/02b77aed6b4383554b3458e408b462098fc3e708) Thanks [@vitbokisch](https://github.com/vitbokisch)! - Add `onFocusIn` / `onFocusOut` JSX event types; Toaster pauses on keyboard focus

  - **`@pyreon/core`**: the JSX event surface now types `onFocusIn` / `onFocusOut`
    — the **bubbling** focus events (unlike the non-bubbling `onFocus` / `onBlur`),
    so a handler on a container fires when focus moves to/from any descendant.
    The runtime already delegated these events (`onFocusIn` → `focusin` via the
    generic `on*` lowercasing + `DELEGATED_EVENTS`); only the types were missing.
  - **`@pyreon/toast`**: the Toaster now mirrors its pause-on-hover with
    **pause-on-focus** (`onFocusIn` / `onFocusOut`), so a keyboard user tabbing
    into a toast (e.g. its close button) pauses auto-dismiss the same way a mouse
    user does on hover.

- [#1642](https://github.com/pyreon/pyreon/pull/1642) [`544c425`](https://github.com/pyreon/pyreon/commit/544c425b6bcf95f772ea04a5e740fb27fa6938d1) Thanks [@vitbokisch](https://github.com/vitbokisch)! - Dependency refresh + Toaster lint annotation

  - **`@pyreon/toast`**: annotated the Toaster's `aria-live` region with a rule
    suppression + rationale for oxlint 1.70's new
    `jsx-a11y/no-noninteractive-element-interactions` rule. The labeled live
    region is the accessibility mechanism (toasts are announced + dismissable);
    pause-on-hover is an intentional mouse-only enhancement on top of it, not a
    clickable control. No behavior change.
  - **`@pyreon/compiler` / `@pyreon/lint`**: bump the `oxc-parser` (+ `oxc-transform`)
    runtime dependency range to `^0.137.0` (was `^0.133.0`). No API change in the
    affected surface — the full compiler (1603) + lint (993) test suites pass.

  Dev-tooling was also refreshed to latest in-range (vitest 4.1.9, playwright
  1.61, esbuild 0.28.1, oxlint 1.70, oxfmt 0.55, happy-dom, etc.) — not
  consumer-affecting.

- [#1719](https://github.com/pyreon/pyreon/pull/1719) [`ee7f09d`](https://github.com/pyreon/pyreon/commit/ee7f09d60f13b0ca6f25d81385ba3f21a6afb25a) Thanks [@vitbokisch](https://github.com/vitbokisch)! - fix(toast): toasts now actually render, update, and respond to clicks

  The `<Toaster>` render layer had two correctness bugs that were invisible to the
  (node-only) store tests because `toaster.tsx` was coverage-excluded with no
  browser test:

  - **Stale rows** — `ToastItem` read `message`/`type`/`state` statically off the
    snapshot the keyed `<For>` callback receives, so `toast.update`,
    `toast.promise` transitions, and the `entering→visible` promotion never
    reflected: toasts rendered stuck in the entering state (`opacity:0` =
    invisible) and updates never changed the text. Rows now read their live fields
    via a `_toastMap` lookup inside reactive thunks — a single update patches only
    that row in place (0 component re-renders).
  - **Dead buttons** — `click` is a delegated event handled at the mount root, but
    the Toaster portals outside it, so the dismiss `×`, the action button, and
    pause-on-focus never fired. The Toaster now renders into a per-instance host
    element and scopes event delegation to it.

  Adds the package's first real-Chromium browser test (8 specs) covering the
  render + a11y + interaction path.

  Every `@pyreon/*` package called `registerSingleton('@pyreon/X', '0.24.6', import.meta.url)`
  with a hardcoded version literal that the release process never bumped — so the
  duplicate-instance sentinel reported `0.24.6` for packages actually shipping
  `0.28.x`. The version is diagnostic-only (detection keys on module location, not
  version), but its diagnostic VALUE is exactly to surface a version skew between
  two installed copies — which a frozen literal silently defeats.

  Name + version are now derived from each package's own `package.json`
  (`import { name, version } from '../package.json' with { type: 'json' }`), so the
  diagnostic is always accurate and can never drift on release. The build inlines
  the strings (no `package.json` bloat); dev reads the live file. No new tooling
  needed — drift is structurally impossible.

  PR 1 of the "whole-repo coverage ≥ 95%" initiative (user-approved sequence:

  Every package in this bump is **already reporting ≥ 95% actual** per

  documenting the lift.

### Patch Changes

- [#902](https://github.com/pyreon/pyreon/pull/902) [`b87fbac`](https://github.com/pyreon/pyreon/commit/b87fbaced0cbeb7304bdc1d358040818e4b1491e) Thanks [@vitbokisch](https://github.com/vitbokisch)! - Ship source maps in published tarballs.

  Every `@pyreon/*` package now ships its `.js.map` and `.d.ts.map` files. The previous `!lib/**/*.map` exclusion in each package's `files` array left every emitted JS file pointing at a `//# sourceMappingURL=*.map` that wasn't actually published — causing Vite (and other bundlers) to log a "Failed to load source map" warning per file on every cold dev start. Real bug in shipped tarballs, not just dev-noise theory.

  The fix is shipping the maps. They make framework stack traces readable: `at mountChild (node_modules/@pyreon/runtime-dom/src/nodes.ts:147)` instead of `at e (node_modules/@pyreon/runtime-dom/lib/index.js:1:42857)`. This matters most when a user hits a framework bug, opens devtools, or sees an unreadable production error from a server-side render. Sentry / Bugsnag / Rollbar can also translate framework frames using the shipped maps; without them, the framework's part of every captured stack stays opaque.

  Cost: ~350KB-1MB per package in `node_modules`. Bundlers (Vite, Webpack, Rollup, esbuild) strip source maps from production builds automatically; they never reach end users. Every comparable library (React, Vue, Solid, Preact, Svelte, TanStack) does this.

  No API changes. The `check-distribution` CI gate inverts to enforce the new contract (maps must be present, not absent).

### Patch Changes

- [#883](https://github.com/pyreon/pyreon/pull/883) [`6075127`](https://github.com/pyreon/pyreon/commit/60751278894a6ff843c0f6f6c4894c76bcb6a720) Thanks [@vitbokisch](https://github.com/vitbokisch)! - Singleton sentinel default-on across every `@pyreon/*` package with module-level state (PR A of the bullet-proof cross-module-instance plan, `.claude/plans/jaunty-herding-kazoo.md`).

  Each package's `src/index.ts` now calls `registerSingleton('@pyreon/<name>', <version>, import.meta.url)` at module load. The first registration records a marker on `globalThis`; a second registration with a DIFFERENT normalized location triggers detection. Default mode throws an actionable Error naming both file paths and three concrete fixes (Vite `resolve.dedupe`, `npm ls`, `bun ls`). `PYREON_SINGLE_INSTANCE=warn` demotes to `console.error`; `PYREON_SINGLE_INSTANCE=silent` opts out entirely (browser extensions, micro-frontends, nested SSR via `rocketstyle-collapse`).

  **HMR-aware.** Vite re-evaluates modules with the SAME path but possibly different query params (`?v=12345`, `?t=12345`, `?import`). The sentinel normalizes the location (strips query string) before comparing — same normalized location → HMR re-eval → silently allowed; different location → genuine dual-instance → throws.

  **Per-package detection.** The earlier prototype put the sentinel only in `@pyreon/reactivity` — insufficient because `@pyreon/core` (and every other package) has its own module-level state that can be silently corrupted under dual-load. The full plan requires per-package registration, which this PR ships.

  **Zero behavior change in correct setups.** Apps that already have a single instance of each `@pyreon/*` package (the overwhelmingly common case) see no runtime change. Apps with silently-tolerated duplicates today (sub-dep version mismatch, custom bundler config) will see their app throw at startup after upgrading with an error message naming the fix. `PYREON_SINGLE_INSTANCE=warn` is the immediate mitigation for any consumer surprised by the change.

  **Test coverage.** Contract tests at `packages/core/reactivity/src/tests/singleton-sentinel.test.ts` (57 specs) exercise the sentinel directly with synthetic `file://` URLs: default-mode throw + actionable error message, HMR re-eval allowance, `PYREON_SINGLE_INSTANCE=warn` / `=silent` escape hatches, per-package coverage across all 24 registered packages, and cross-package isolation. Bisect-verified — neutralizing the throw branch fails 49 positive-case tests; restored passes all 57. The synthetic-URL approach replaces the heavier filesystem dual-load reproducer (it's the sentinel's normalized-string comparison that matters, not Node's ESM loader behaviour).
