The dependency evidence in docs/reading-the-log.md was the #[Cacheable] shape only: a depends_on edge, the child's tags merged into the parent's save tags, and a parent cache_miss once the child is purged. The two donut declarations record it differently, and the docs now say so per declaration:

  • #[Cacheable]: a depends_on edge, the child's tags on save_value/save_view, and a parent miss after the child is purged.
  • #[CacheableResponse]: no edge; the child's URI tag on save_etag/save_donut_view, never on save_donut; after a child purge the parent still closes cache_hit{layer: donut-view} with refresh_donut inside. A hit without refresh_donut is the stale shape.
  • #[DonutCache]: no child tag stored at all (they reach only cdn_headers.surrogateKeys); every read after the first is refresh_donut + put_skipped{not-cacheable}.

DonutDependencyEvidenceTest pins the three shapes on the fake app. SemanticLogTreeTrait gains the scope-close and own-event helpers it needs. docs/reading-the-log.ja.md, docs/llms.txt, docs/llms-full.txt and tests/CACHE_DEPENDENCY_TESTS.md carry the same facts.

Follows up on the per-declaration point raised in #188. The harness side is in bearsunday/BEAR.Skills#30.

🤖 Generated with Claude Code

A depends_on edge and a parent miss after the child is purged are the
#[Cacheable] shape only. A #[CacheableResponse] parent carries the child's
tags on save_etag/save_donut_view and closes cache_hit{donut-view} with a
refresh_donut inside; a #[DonutCache] parent records them in
cdn_headers.surrogateKeys and nowhere else. DonutDependencyEvidenceTest
pins the three shapes (bearsunday#188).

📝 Walkthrough

Walkthrough

The change adds semantic-log tests for dependency evidence across three cache declarations. It adds log-tree inspection helpers and updates English, Japanese, LLM, test, and changelog documentation.

Changes

Cache dependency evidence

Layer / File(s) Summary
Semantic log inspection helpers
tests/SemanticLogTreeTrait.php
The test trait now filters event contexts, locates URI-specific scopes, returns scope close data, and collects events within scopes.
Declaration-specific dependency tests
tests/DonutDependencyEvidenceTest.php
New tests validate depends_on, child-tag placement, cache hit and miss shapes, refresh_donut, put_skipped, and CDN surrogate keys for #[Cacheable], #[CacheableResponse], and #[DonutCache].
Dependency evidence documentation
CHANGELOG.md, docs/llms*.txt, docs/reading-the-log*.md, tests/CACHE_DEPENDENCY_TESTS.md
Documentation now describes declaration-specific dependency edges, tag storage, and post-purge log events.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Merge Risk: 🔵 Low · up to cb2fd

Future tag-placement regressions can pass undetected, and cache-log users may not know where to inspect Cacheable child tags. Complete the test assertions and lookup documentation before merge.

@coderabbitai Both applied in 2b8c01b. The llms lookup files now name save_value/save_view and save_etag as the #[Cacheable] destinations, matching reading-the-log.md. The test asserts the edge's child and childTags, adds testCacheableParentTagsValueAndEtagWithTheChild for the parent's own saves, and checks the child's Surrogate-Key on save_donut (absent) and cdn_headers (present) next to the URI tag.

The llms lookup files named the save events that carry a child's tags
for the two donut declarations but not for #[Cacheable]; they now say
save_value/save_view and save_etag, as reading-the-log.md already did.

DonutDependencyEvidenceTest asserts the depends_on edge's child and
childTags rather than only that an edge exists, pins the child's URI
tag on the #[Cacheable] parent's save_value and save_etag, and checks
the child's Surrogate-Key alongside its URI tag on the #[DonutCache]
save_donut and cdn_headers assertions.

@koriym Verified commit 2b8c01b.

The llms lookup files now match reading-the-log.md for the #[Cacheable] save destinations. The test now verifies the depends_on payload, the parent save_value and save_etag tags, and the Surrogate-Key boundary between save_donut and cdn_headers.

eventContextJsonOf() duplicated the depth-first, events-before-open-scopes
walk that eventContextsJsonOf() already does generically. Delegating to
eventContextsJsonOf($tree, $type)[0] ?? null keeps the same signature and
first-match semantics for all 46 existing callers and drops the now-dead
findEventContextJson().
