Bind command methods on the donut path to the command interceptor - #215
Conversation
A write annotated #[RefreshCache], or carrying a method-level #[CacheableResponse], was woven with DonutCacheInterceptor. That interceptor answers from the donut store and returns before proceed(), so once the page was cached the write never ran: onPut / onPost / onDelete answered 200 with the cached representation instead of their own. Measured on a 36-cell weaving matrix - 9 cells lost the write, and #[DonutCache] escaped only because it stores no entire-content entry to hit. Both now bind DonutCommandInterceptor, which proceeds first and then purges and refreshes - what #[RefreshCache]'s own docblock promises. The class-level write matcher also missed onPost, the gap bearsunday#212 fixed on the value-cache side and this one did not. DonutCommandInterceptorTest asserted the wrong binding, which is why 368 tests stayed green over a write that did nothing.

- Line 121: Update the AOP binding configuration around DonutCommandInterceptor
so methods already matched by the class-level binding are excluded from the
overlapping CacheableResponse or RefreshCache binding, preventing duplicate
execution of CRRefresh::onPost. Add assertions verifying that the interceptor
runs once and performs one invalidation operation.

CodeRabbit caught it on bearsunday#215: a write on a #[CacheableResponse] class that also carries #[RefreshCache] matched both new bindings, and Ray.Aop merges overlapping bindings without deduplicating. Measured before: CRRefresh::onPost carried DonutCommandInterceptor twice and answered with command=2 purge=2. After: one of each. WeavingMatrixTest now asserts the woven chain holds no duplicated interceptor class, so the next overlapping matcher fails here rather than doubling a CDN purge in production. The remaining two-interceptor case is not a duplicate: #[Purge] on a #[CacheableResponse] class weaves RefreshInterceptor (purges the URI the attribute names) alongside DonutCommandInterceptor (refreshes the resource itself) - two jobs that coincide only when the attribute points at its own URI, as the fixture does.

One two-interceptor case remains and is not a duplicate: |

The duplicate check on interceptor classes could not see two different interceptors doing one job twice, so the matrix now asserts the exact number of command scopes a write opens. Two overlaps that count made visible: - a #[Cacheable] class with #[RefreshCache] on a write wove DonutCommandInterceptor beside CommandInterceptor: both purge the resource and regenerate it, measured as command=2 purge=4 - a class declaring #[CacheableResponse] and repeating it on onGet wove DonutCacheableResponseInterceptor beside DonutCacheInterceptor, and a #[DonutCache] class repeating #[CacheableResponse] on onGet wove the same donut interceptor twice The method-level bindings now skip a class whose own declaration governs the method. The read set excludes #[DonutCache] as well as the write set does not: #[DonutCache] binds onGet only, so excluding it from the write bindings leaves a #[RefreshCache] write with no interceptor at all - the defect this branch exists to fix, which one measurement caught. CRPurge keeps two scopes on purpose: RefreshInterceptor purges the URI the attribute names, DonutCommandInterceptor refreshes the resource. Fixtures CRBoth and DCMR cover the repeated declaration; DC* now declare #[DonutCache] on the class, which is the only form any binding reads - a method-level #[DonutCache] is accepted by the attribute and implemented by nothing.

Follow-up in 1dd0e29: the duplicate check on interceptor classes could not see two different interceptors doing one job twice, so the matrix now asserts the exact number of command scopes a write opens. That count made two more overlaps visible, both pre-existing in shape but reachable through the new bindings:
The method-level bindings now skip a class whose own declaration governs the method. The read and write exclusion sets differ deliberately:

The defect this branch fixes was an ordering fact: the query interceptor sat first and answered the write from the store. A count cannot see order, and counting purges would break on any change to how many URIs a command touches. The provider now holds the exact chain per shape, by ::class, and the scope count beside it - the chain is the weaving contract, the count is what the chain did at runtime.

The log answers questions no test can see, but only if the reader knows which event answers which question. This file is that reader's instructions, written for a coding agent: turn recording on, prove the wiring reaches the pool, map a declaration to the event sequence it must produce, and when the two disagree, decide whether the fault is the application's or this library's before reporting it. Everything in it was measured on 1.x rather than reasoned: the declaration-to-event table comes from demo/run*.php and the weaving fixtures, the traps come from defects this cycle produced (a #[Cacheable] final class weaves nothing, #[RefreshCache] on a write was answered from the cache until #215, an invalidation tag drifted from the constant it was copied from), and four agents given nothing but this file and a symptom reached the cause from the log each time. Placed under docs/ with the other log documents, so a curl of the raw URL installs it into an agent's skill directory.

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 thequery-side
DonutCacheInterceptor. That interceptor reads the donut store and returns beforeproceed(), so once the page was cached the write never executed:onPut/onPost/onDeleteanswered
200with the cached page instead of their own response, and nothing was invalidated.Both now bind
DonutCommandInterceptor, which proceeds first and then purges and refreshes —what
#[RefreshCache]'s own docblock promises. The class-level write matcher also missedonPost, the gap #212 fixed on the value-cache side and this one did not.The pattern is the one the manual documents (
Todo::onDeletewith#[RefreshCache]), so anapplication written from the manual loses writes silently.
tests/WeavingMatrixTest.phpenumerates the 12 declaration shapes an application can write ×onPut/onPost/onDelete, and asserts on two observable facts per cell: the write body ran,and the write announced the change where a declaration names one. Reverting
src/DonutCacheModule.phpturns 13 of the 36 cells red.Not fixed here, and documented in the test: a shape whose declaration sits on
onGetalone(
MRNone,DCNone) still needs#[Purge]/#[Refresh]on the write — the binding matches theattribute on the method, and no matcher can express "a class holding this attribute somewhere".
