Subject: [PATCH] Remove moving a set between packs (package.replaces)

It existed only so icon-sets-emoji's openmoji-* ids kept resolving after
OpenMoji moved to icon-sets-openmoji. The owner removed the emoji copies,
so nothing declares it. Removes PackAliases, the replaces and deprecated
marker readers, canonicalId/isReplaced/packAliases, the deprecation log
method, the seeder and watcher skips, and doctor's alias checks.

@@ -10,12 +10,11 @@ All notable changes to `ichava/core` follow [Keep a Changelog](https://keepachan
 - **`IchavaConstants::PACK_COMPOSER_TYPE`** (`ichava-icon-set`), the composer `type` a pack declares so discovery can find it.
 - **Kind resolution covers every D6 row** (K1, contract §1–2). Besides a category's `kind` and `package.kind`, a pack can now declare kind per item (`metadata.data.items.<item path>.kind`) and by ordered glob rule (`metadata.data.kinds.rules[]`, first match wins), and a host can override any of it in `ichava.ichava-core.kinds.overrides` (`'<vendor/pack | *>::<glob or exact item path>' => kind`, exact keys before globs). The order is host, item, rule, category, pack, then `icon`. New `Support\KindGlob` (`*`, `?`, whole-segment `**`; the contract's vector table is its test), `Support\KindResolver`, `Enums\KindSource` and the `final readonly` DTO `Data\KindResolution`; `PackConfigData::items()`/`kindRules()` read the new keys from the documented shape and the top level. `IconRegistry::kindOf()`, the renderer's size budget and `IconClassifier::kind()` all resolve through `KindResolver`; `IconRegistry::kindFor()` keeps its category/pack behaviour for its callers. A v0.1 `config.json` with no kind keys loads exactly as before. `tests/Unit/KindGlobTest.php`, `tests/Feature/KindResolutionTest.php`.
 - **Each row records which rule decided its kind.** Migration `2026_11_04_000001_add_kind_source_to_ichava_icons` adds `kind_source` (string(16), default `default`) and `kind_rule` (string(255), nullable), additive on all four drivers and reversible. The seeder and the watcher write both from `IconClassifier::resolution()`, and both join change detection, so a new override re-files unchanged files without `--force`. `Icon::kindSource()` and the `kind_source` cast. `transformIcon()` adds `kind_source`; `kind_rule` stays out of the API because it can carry host config.
-- **`Ichava::kindOf()`, `Ichava::kindResolution()` and `Ichava::canonicalId()`** on the facade (K5).
+- **`Ichava::kindOf()` and `Ichava::kindResolution()`** on the facade (K5).
 - **Per-kind counts per pack** (contract §5.2): `getStatistics()['by_package_kind']` (`[]` when nothing is seeded) and `by_kind` on each package in `getFilters()`, within the current filters. `getIcons()` takes several kinds (`'kind' => ['icon', 'illustration']`), OR-ed, duplicates collapsed.
 - **`artisan about` reports kinds** (K3/D4): `Icons by kind`, `Default kind` (the first reader of `IconKind::default()`, K2/D3), `Kind sources` and `Kind overrides`.
-- **Doctor kind and alias checks** (contract §7): `kind.invalid_value`, `kind.invalid_glob`, `kind.override_invalid`, `kind.rule_unused`, `kind.item_missing`, `kind.drift` (with the seed command to run), `kind.non_default`, `alias.deprecated_ids` and `alias.replacement_missing`, all warnings. `--format=json` now prints every doctor check as `{id, status, count, detail}`. New `Services\KindDoctor`. `tests/Feature/KindDoctorTest.php`.
+- **Doctor kind checks** (contract §7): `kind.invalid_value`, `kind.invalid_glob`, `kind.override_invalid`, `kind.rule_unused`, `kind.item_missing`, `kind.drift` (with the seed command to run), and `kind.non_default`, all warnings. `--format=json` now prints every doctor check as `{id, status, count, detail}`. New `Services\KindDoctor`. `tests/Feature/KindDoctorTest.php`.
 - **A kind heuristic that suggests and never applies** (D6 row 7, contract §3). `doctor --suggest-kinds[=default|all]` reads every SVG and suggests `illustration` for a default-row icon when three of `aspect`, `palette`, `bytes`, `elements` and `canvas` fire, one of them `bytes` or `elements`; a mostly suggested folder becomes one `<folder>/**` rule. Thresholds are `IchavaConstants::KIND_HEURISTIC_*`, shared with icon-sets-sync. Nothing writes a suggestion anywhere.
-- **A set can move to another pack** (D9, contract §8). A pack declaring `package.replaces` takes over the listed item paths of another pack: with it installed, the old id resolves in the new pack wherever an id is parsed, each rewritten id is logged once per process as `[DEPRECATED]`, and the old pack's moved categories are not seeded. Without it nothing changes. New `Support\PackAliases` and `PackConfigData::replaces()`/`deprecatedCategories()`. `tests/Feature/PackAliasTest.php`.
 - **`<x-ichava-core::icon>`, the vendor-scoped spelling of the icon component** (V-B11). Core registers the `ichava-core` Blade prefix over the same component classes, plus the `ichava-core::icon` alias, so `<x-ichava-core::icon>` and `<x-ichava::icon>` resolve the same class and render the same bytes. Additive: the bare `ichava` prefix and alias are unchanged. `IchavaServiceProvider::SCOPED_COMPONENT_PREFIX`. `tests/Feature/ComponentNamespaceDeferralTest.php` reads Blade's live namespace and alias maps, and fails on any new unscoped core alias.
 - **A `dark` twin on the icon component** (V-B10). `<x-ichava::icon name="…" dark="…">` renders both SVGs in a `<span class="ichava-themed">`, with `ichava-theme-light`/`ichava-theme-dark` classes and a nonce-carrying `<style>` that shows one at a time. New config `theme_variants.dark_mode` (`media`, by `prefers-color-scheme`, or `class`, by a `.dark` ancestor; `ICHAVA_DARK_MODE`) and `theme_variants.auto_dark` (`ICHAVA_AUTO_DARK`, off), which renders the twin a pack's category declares when no `dark` is passed. New `IconRegistry::themeTwin()`. Without `dark` and with `auto_dark` off the output is byte-identical to before (golden files). `tests/Feature/IconComponentDarkVariantTest.php`.
 - **`IconRenderer::role(null)` omits the `role` attribute** (V-B9). The default stays `role="img"`, byte for byte. `tests/Feature/IconRendererRoleTest.php`.
@@ -56,6 +55,7 @@ The estate is forward-only (owner, 2026-11-05: "never support legacy only forwar
 - **The `ichava` container alias for `Ichava::class`.** The facade resolves `Ichava::class`; nothing in the estate or the demos called `app('ichava')`, `resolve('ichava')` or `make('ichava')`. Resolve `Ichava::class`, or use the facade.
 - **`IconDiscoveryService::registerPackage()`**, documented as "for testing/legacy purposes". It wrote a cache key nothing read, and had no caller.
 - **`IconPreferenceService`'s pre-taxonomy fallback.** The available categories and variants were read from `ichava_icons.category` / `variant` when `ichava_icon_terms` did not exist; core's first migration creates that table, so they are read from it alone.
+- **Moving a set between packs (`package.replaces`, D9).** It existed so that `ichava/icon-sets-emoji::openmoji-*` ids kept resolving after OpenMoji moved to `ichava/icon-sets-openmoji`. The owner removed the emoji copies (2026-11-05), so nothing declares it any more. Gone with it: `Support\PackAliases`, `PackConfigData::replaces()` and `deprecatedCategories()`, `IconRegistry::canonicalId()`, `isReplaced()` and `packAliases()`, `Ichava::canonicalId()`, `IchavaLogger::deprecation()`, the seeder's and the watcher's skip of replaced items, and doctor's `alias.deprecated_ids` and `alias.replacement_missing`. A `package.replaces` key or a category's `deprecated` marker in `config.json` is now ignored. An OpenMoji id is `ichava/icon-sets-openmoji::openmoji-color/…`.
 - `tests/Unit/NoDeprecatedSymbolsTest.php` fails if an `@deprecated` tag appears anywhere in `src/` (it asserts it read at least 100 files).

 The `kind` column defaults to `icon` and `kind_source` to `default`, which is also the backfill for rows seeded before either existed.
 
-## A set that moved to another pack
-
-A pack that takes over a set from another declares it, and the old pack marks the moved categories deprecated:
-
-```json
-"package": {
-  "name": "ichava/icon-sets-openmoji",
-  "replaces": [ { "package": "ichava/icon-sets-emoji", "paths": ["openmoji-color/**"], "since": "0.1.0" } ]
-}
-```
-
-With the replacing pack installed, `ichava/icon-sets-emoji::openmoji-color/1f600` resolves to `ichava/icon-sets-openmoji::openmoji-color/1f600` wherever an id is parsed (Blade, the helper, render and `kindOf`), and `Ichava::canonicalId()` returns the new id for callers that look ids up themselves. Each rewritten id is logged once per process to the `ichava` channel as `[DEPRECATED]`. The old pack's moved categories are not seeded, so nothing is counted twice. Without the replacing pack the old id resolves in the old pack, as before.
-
-Doctor's `alias.deprecated_ids` scans `app/`, `resources/views`, `resources/js` and `config/` for old ids and reports each `file:line` (up to 50); `alias.replacement_missing` warns when a deprecated set is installed and its replacement is not.
