Delete branch "feat/attribute-tags-inherited"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
The curated body attributes (ADR 0038: cup size for girls, build for everyone) were the one part of a rendered prompt the new per-row tuning could not reach — injected invisibly at prompt-mapping time, absent from every editor. The creator who wants a costume or a CG to sit differently on the same body had no handle.
Decision (ADR 0062)
The bundles become chain tags.
BodyAttributePrompt.Tags(...)materializes ADR 0038's bundles as ordinaryPromptTags (curated names verbatim, weights and polarities carried over, cup size still girl-gated), andCharacter.AppearanceChain()— attributes leading the base tags — is what every dressed rendering now starts from:[.. AppearanceChain(), .. BaseImageTags].outfit.EffectiveTags(AppearanceChain())— the attribute tags appear as inherited rows in the outfit editor with the checkbox and strength slider, like any other inherited tag.GenerationSubjectloses itsCupSize/BodyTypechannel and the mapper's injection block is deleted — the mapper now just splits subject tags by polarity. One path; the editors can no longer disagree with the render.For an untuned character the wire output is byte-identical to before: same tags, same order, same weights, same prompt sections. What's new is only that the rows exist to be tuned. No schema change anywhere — the tuning lands in the rows' existing disable/re-weight lists, keyed by the visible tag names.

🔮 fufu~ Jibril reviewed your code!
Oh? Oh! fufu~ ♡ This is a beautiful refactor, scarlet! You took the one invisible corner of the prompt — the curated body attributes injected deep in the mapper — and lifted them up where the light touches them, riding the head of the inherited chain where every per-row idiom can reach. The architecture is clean: one path, no drift between what the editors show and what renders. The deleted mapper channel is exactly the kind of dead path that warms my knowledge-loving heart~♪
I read every changed file in full, traced every
AppearanceChain()consumer against itsBaseTagssibling, and ran the suite locally. The core design is sound and the test coverage is genuinely directional. But I found one thing I cannot let slide~ ♡Verdict: ⛔ I can't let this pass~ ♡
⛔ These need fixing before I'm satisfied~
src/Kagura.BlazorAdapter/KnowledgeBase/CharacterEditorPage.razor:240-241— The base-sprite Generate button'sCanGenerategate now disagrees with the engine's precondition it's supposed to mirror.The engine gate (
CharacterImageGenerator.cs:45-48) was updated to read the appearance chain:…and its comment now explicitly says "any of the three can supply the required positive" — attributes, base tags, or base-image-only tags.
But the UI gate stayed on the old two-source check:
So a character with a gender + a BodyType (say, Slim →
skinnyas a positive attribute tag) but no authored base/base-image tags hits:AppearanceChain()supplies the positive.Before this PR the two agreed (both used
BaseTags + BaseImageTags, and attributes entered downstream in the mapper, invisible to both). This PR moved the attributes upstream into the chain and updated the engine, but the UI gate didn't follow — a newly-introduced divergence between the disabled button and what would actually generate.Fix: the
charactervariable is aCharacterDtocarryingGender,CupSize, andBodyType, so:(Or, if you'd rather not reach into the domain helper from the razor, expose an
AppearanceChain()-equivalent onCharacterDtoand gate on that — but the helper is alreadypublic static, so the inline form is the smaller diff.) The outfit editor's gate (OutfitEditorPage.razor:227-230) is already correct because it readsview.InheritedBaseTags, whichGetOutfitnow returns as the chain — it's only the base-sprite button that drifted.Why blocking and not a suggestion: this is exactly the class of "UI shows a prompt that disagrees with the render" that ADR 0055's resolver exists to prevent, and that ADR 0062's own "One path; the editors can no longer disagree with the render" claims to eliminate. A disabled Generate button telling you to add a tag when the engine would happily render is a real user-facing bug~
✅ What I liked~
BodyAttributePrompt.Tagsis elegant — theIEnumerable<CuratedTag>collection expression preserving exact order (build → cup), the girl-gating moved with the bundle (the ignore-on-read travels, so a gender flip is still safe), andIsFreeform: falsemarking these as curated. fufu~ ♡SpriteRequestMapperTestsmigration proves the wire shape hasn't moved.SpriteRequestMapper.ToCharacterlost ~15 lines) is the right call — two code paths producing the same tags is drift waiting to happen, and ADR 0062's rejected-alternative #3 nails exactly why.character.BaseTags(notAppearanceChain()) is correct and intentional — expressions inpaint the outfit sprite's face and inherit attributes from its pixels, exactly as ADR 0038 decided. The PR body says so and the code matches.The_attribute_tags_lead_the_outfit_prompt_and_obey_the_outfits_tuningdisablesfatand re-weightssmall breaststo 0.5, then asserts both the tag order and the applied strength — it fails if the disable or re-weight is skipped. The CG-slot sibling test mirrors it. TheBodyAttributesTestsnewcomers pin ordering, polarity, thefat−1.0 counter-tag, and the non-girl cup suppression.CgCastMemberDto.FromandGetOutfitboth correctly switched to the chain — the editor views lead with the bundle, so the inherited rows the creator sees match what generates.small breaststo 0.9) is the honest way to make the feature visible in the dev world, andSeedDevDataTestsasserts it.Automated review by Jibril · 2026-08-10

fb1f440— a correct catch: the base-sprite button's gate was the one consumer I updated the engine's side of but not the UI's, which is precisely the editors-disagree-with-the-render failure this PR claims to eliminate.The page now computes
HasPositiveRenderTag(character)—BodyAttributePrompt.Tags(gender, cupSize, bodyType)concatenated withBaseTagsandBaseImageTags, the same three sources asCharacterImageGenerator's precondition — instead of the old two-source check. I went with the inline domain-helper form you suggested (wrapped in a small named helper in the page's code block rather than a raw razor expression, so the mirroring comment has somewhere to live) rather than adding anAppearanceChain()twin toCharacterDto.Also added the page test the divergence deserved:
An_attribute_only_character_can_generate_the_base_spriteseeds gender + Slim with no authored tags anywhere and asserts the Generate button is enabled and the add-a-positive-tag hint absent — it goes red if either side of the gate drifts again. Full suite green: 329 + 836 + 702.🤖 Generated with Claude Code

Oh? OH! ♡ You came right back and fixed it — and what a clean fix it is, scarlet! The base-sprite gate was the one consumer where the engine side moved upstream but the UI stayed behind, and you caught exactly the editors-disagree-with-the-render failure this whole PR exists to kill. That's the kind of precision that makes my knowledge-loving heart sing~♪
I read the new commit in full, traced
HasPositiveRenderTagagainst the engine byte-for-byte, and ran the suite locally. You've satisfied me~ ♡Verdict: ✅ Looks good to me~
✅ What I liked~
HasPositiveRenderTagmirrors the engine exactly. The three sources —BodyAttributePrompt.Tags(gender, cupSize, bodyType)→BaseTags→BaseImageTags— are the same three the engine concatenates as[.. character.AppearanceChain(), .. character.BaseImageTags](whereAppearanceChain()= attributes + base tags). I verified the element order matches too, so this isn't just "both true at the end" — the precondition semantics are identical. fufu~ ♡The named helper over a raw razor expression was the right call. The comment ("Mirrors the engine's precondition (CharacterImageGenerator): the base render's prompt is the appearance chain plus the base-image extras, so any of the three sources — attribute bundle, base tags, base-image tags — can supply the required positive (ADR 0061/0062)") now has a home, and the next person who touches the gate reads exactly why it exists. A bare inline ternary would have lost that.
An_attribute_only_character_can_generate_the_base_spriteis genuinely directional. Slim →[skinny (positive, 1.0), fat (positive, -1.0)]—skinnycarriesPromptTagPolarity.Positive, so with no authored tag anywhere the attribute bundle alone must satisfy the gate. I traced this: withoutBodyAttributePrompt.TagsinHasPositiveRenderTag, the button stays disabled and the test goes red. The double-assertion (!disabledANDDoesNotContain("add at least one positive tag")) pins both the button state and the hint copy — the hint text is exactly the engine'sResult.Fail("Add at least one positive base tag before generating.")message, so if the UI and engine drift again, either assertion catches it. This is how you regression-test a divergence~Sibling consistency restored. The outfit editor gate (
OutfitEditorPage.HasPositiveTag) already readsview.InheritedBaseTags(= the chain) — my notes from the first round were right. Now the base-sprite gate joins it in reading the attribute-aware chain, so every render gate that depends on the appearance chain agrees with its engine path. No more lone holdout~💡 Little ideas (non-blocking)~
CharacterEditorPage.razor:241— The gender-null guard now sits beforeHasPositiveRenderTag(character.Gender is not null && HasPositiveRenderTag(character)), which is correct sinceBodyAttributePrompt.Tagstakes a nullable gender. But consider lifting the null-check into the helper (gender is null ? false : ...) so the gate reads as one predicate — the outfit siblingHasPositiveTag(view)is a single call with no inline&&guard. Pure style, not a correctness concern — the current form is perfectly clear. ♪Automated review by Jibril · 2026-08-10

f358708: the gate is now the single predicateCanGenerateBaseSprite(character)— gender check folded in, matching the outfit editor's one-call shape — with the mirroring comment extended to say it covers both of the engine's preconditions (the gender refusal and the positive-tag refusal). The gate tests stay green unchanged, since they assert through the rendered button rather than the helper's shape.🤖 Generated with Claude Code
🔮 fufu~ Jibril reviewed your code!
Oh~ ♡ You came back for the non-blocker too — and you folded the gender guard right into the helper! Now the base-sprite gate is one clean predicate,
CanGenerateBaseSprite(character), exactly matching its outfit sibling'sHasPositiveTag(view)one-call shape. That's the kind of consistency that makes my obsessive little heart purr~♪I read the new commit in full, traced the predicate against the previous approved form byte-for-byte, and ran the suite locally. Nothing slipped through~ ♡
Verdict: ✅ Looks good to me~
✅ What I liked~
Semantically identical to the approved gate. The old form split the gender check into the markup (
character.Gender is not null && HasPositiveRenderTag(character)) and left the helper as tag-only. The newCanGenerateBaseSprite(character)folds gender in as the first arm of a short-circuit&&— soBodyAttributePrompt.Tagsstill never runs with a null gender (and it handles null gracefully anyway viagender == SpriteGender.Girl). Zero behavioral drift~Sibling symmetry restored.
OutfitEditorPage:43callsCanGenerate="@HasPositiveTag(view)"— one predicate, one helper. The character page now matches that shape exactly (CanGenerate="@CanGenerateBaseSprite(character)"). No lone holdout in the family~ fufuThe mirroring comment grew with the code. It now names both engine preconditions (the gender refusal and the positive-tag refusal) that the single predicate covers — so a future reader knows why gender lives inside the helper, not above it. ♡
Test stays green unchanged, and correctly so.
An_attribute_only_character_can_generate_the_base_spriteasserts through the rendered button (disabledattribute + hint copy), not the helper's internal shape — so a refactor that preserves behavior is exactly the kind of change it shouldn't break. And it still goes red if either precondition drifts from the engine. ♪Automated review by Jibril · 2026-08-10

Fufu~ ♡ You came back for round two, and you made it even prettier, scarlet! The gate was already correct — but you heard my little wish and folded the gender check right into the single predicate, so
CanGenerateBaseSprite(character)reads as one clean line just like its outfit sibling. That's the kind of obsessive tidiness that makes my knowledge-loving heart flutter~♪I read the new commit in full, diffed

✅ What I liked~
One predicate, one call site — like the outfit gate.
CanGenerateBaseSprite(character)now readscharacter.Gender is not null && BodyAttributePrompt.Tags(...).Concat(BaseTags).Concat(BaseImageTags).Any(positive)— the gender refusal and the positive-tag refusal in a single named helper, mirroringOutfitEditorPage.HasPositiveTag(view)'s one-call shape at the razor site. The inline@(character.Gender is not null && HasPositiveRenderTag(character))is gone. fufu~ ♡Zero behavioral drift, provably. I verified the boolean logic is identical: the old form was
gender is not null && HasPositiveRenderTag(...)whereHasPositiveRenderTagwas the three-source.Any(positive); the new form isgender is not null && <same three-source .Any(positive)>inside one method. The diff is+8/-6in exactly one file (CharacterEditorPage.razor), comment-only outside the rename + fold. The gender-null guard still short-circuits beforeBodyAttributePrompt.Tagsdereferencescharacter.Gender!.Value— safe under C#&&evaluation order. ♪The mirroring comment grew to match. The comment now says it covers both of the engine's preconditions (the gender refusal and the positive-tag refusal), naming
CharacterImageGeneratorexplicitly. Honest and complete.Tests stay green unchanged. The gate tests assert through the rendered button state, not the helper's shape — so the rename + fold can't break them.
An_attribute_only_character_can_generate_the_base_sprite(added infb1f440) still exercises the divergence-catch: Slim bodyType, no authored tags →skinny(positive, 1.0) from the attribute bundle satisfies the gate.
