 ### Fixed
 - Donut caching could not handle a non-200 response, in two ways (#206). The save gate skips 4xx and above, so a `301` or a `204` is stored, but `saveView()` required a validator that `EtagSetter` issues for 200 only: under `#[CacheableResponse]` every such request died on that assertion (a `TypeError` converted to a 400 with `zend.assertions=-1`), and a `204` leaving its body null died earlier still, in `ResourceDonut::create()`. Under `#[DonutCache]` nothing threw and the page answered 200 with the `Location` header attached from the second request on, because neither `DonutRepository::get()` nor `ResourceDonut::refresh()` restored the code the entry was saved with. The validator is now saved only when the response has one, `ResourceDonut` carries the code through the refresh (entries serialized before it leave the response's own code alone), and a null body is composed as an empty one. Behaviour change: a `#[CacheableResponse]` or `#[DonutCache]` page that answers 2xx or 3xx is now served with that status instead of crashing or degrading to 200 - a redirect that was reachable only once now persists until its cache entry is invalidated, so such a page needs the surrogate keys that invalidate it.
 - `onPost` on a `#[Cacheable]` class ran with no interceptor at all (#212): `CommandInterceptor` was bound to `onPut`/`onPatch`/`onDelete`, and `RefreshInterceptor` only to classes that are not `#[Cacheable]`. A POST - the method a form submits - left the representation it had just made stale being served, and a `#[Refresh]`/`#[Purge]` written on it was dropped with no error and no log event.
+- `onPost` on a `#[Cacheable]` class whose parameters did not cover `onGet`'s required ones threw `UnmatchedQuery`, uncaught (#219, a regression from #214 above): `RefreshSameCommand`'s automatic same-URI refresh runs `MatchQuery` against the write's own URI query, and a create posting to a collection URI routinely lacks a parameter `onGet` needs. The write itself already succeeded; the refresh had nothing to target. The same gap existed on the donut path: `DonutCommandInterceptor::refreshDonutAndState()` called `MatchQuery` with no catch either, so a `#[CacheableResponse]`/`#[DonutCache]` collection `onPost` with the same shape 500ed too. Both interceptors now catch `UnmatchedQuery` for `onPost` specifically and record it as a `cache_error{operation: write}` instead; `RefreshSameCommand` returning rather than throwing also lets `CommandsProvider`'s next command run, so an explicit `#[Refresh]`/`#[Purge]` on the same method still fires. `onPut`/`onPatch`/`onDelete` keep throwing on both interceptors: those act on an entity `onGet` already addresses, so a missing required parameter there is a real signature mismatch (`BehaviorTest::testUnMatchQuery`).
 - A write on the donut path could be answered from the cache without running: `#[RefreshCache]`, and a method-level `#[CacheableResponse]` on a command method, bound the query-side `DonutCacheInterceptor`, which returns the stored representation and never calls `proceed()`. Once the page was cached, `onPut`/`onPost`/`onDelete` did nothing and answered 200 with the cached page instead of their own response; both now bind `DonutCommandInterceptor`, which runs the write and then purges and refreshes. `DonutCacheModule` also missed `onPost` in its class-level write matcher, the same gap #212 fixed on the value-cache side. `tests/WeavingMatrixTest.php` asserts that a write runs for every declaration shape, and that it announces the change where a declaration names one - a shape whose declaration sits on `onGet` alone still needs `#[Purge]`/`#[Refresh]` on the write, which no matcher can supply.
 - `DevEtagSetter` and `MobileEtagSetter` set a validator regardless of the response code, where `EtagSetter` has always skipped a non-200. With a stored `301` now reaching them through the donut refresh, an `If-None-Match` match would have let `ConditionalResponse::isModified()` answer `304` in place of the redirect; both now skip a non-200. `CdnCacheControlHeaderSetterInterface` is likewise called for 200 only, so a stored non-200 is no longer handed the Fastly/Akamai default shared-cache lifetime of a year.
 - A client-chosen `If-None-Match` token containing a PSR-6 reserved character (`{}()/\@:`) reached the ETag pool as a cache key and threw, turning a request header into a 500 that logged like a pool outage. Such a token can never have been issued by this server, so `EntityTags` drops it and the request is answered in full; `*` is likewise dropped (RFC 9110 §13.1.2 gives it existence semantics this package does not implement).
