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 project style reference (ADR 0027) rode every generation at the vendor's 1.0 strength/fidelity. The outfit's likeness sliders (ADR 0043) showed that full strength crowds out a record's own tags — and the right value is not one number for a whole project, so the tuning lands on the records themselves, not on the project. There is deliberately no project-wide pair.
What this adds
StyleReferenceControlspanel on their own editors — the character's Appearance tab, the location's Backgrounds tab, the variation page. Auto-saved and journaled like every other field.Use style reference: true → false).Generation
SpriteGenerationSpec.StyleReference(bare bytes) becameStyleof typeStyleReference(bytes, strength, fidelity), mirroringLineageReference. The mapper stops hardcoding 1.0, every generator hands its record's tuning toSpriteEnrichment, and a record that turns the reference off never reads the image from disk.Two routing decisions worth reviewing:
Behaviour change to be aware of
The migration backfills existing rows to 0.65 strength, so every existing project's next generation follows its style image less strongly than before. That is the point of the change (the outfit sliders' staging finding, applied to the style channel) and it is one slider away from the old behaviour.
Contracts kept
Verification
1531 tests green (306 UseCases / 656 BlazorAdapter / 569 Integration), including new coverage for all three editors, the tuned and turned-off generator paths, the mapper's authored entry, and the agent-partial-edit preservation across characters, locations and variations.
Browser-verified against the seeded sample world: each editor renders its seeded values, saves on change, and survives a reload; the unticked state disables both sliders while keeping their values; the history panel shows the change as its own labelled line.

🔮 fufu~ Jibril reviewed your code!
Oh? Oh my~ ♡ A whole feature threaded through three record types, four generators, five tools, three editors, an ADR, a migration, and a seed — and it catches a drive-by
VoiceProviderIdbug on the way? This is the kind of code review that makes a Flugel's heart sing. Let me look closer, fufu~Verdict: ✅ Looks good to me~
This is meticulously done. The per-record tuning lands exactly where the staging finding pointed it, the "follows its character" outfit routing is the right call, and the expression-infill exception is honestly documented with its evidence-first reasoning. I looked hard. I found nothing that blocks. The few notes below are genuine niceties~
💡 Little ideas (non-blocking)~
tests/Kagura.Integration.Tests/LocationImageGenerationTests.cs:167— The existing location-with-style-reference test assertsspec.Style.Strengthequals the default but doesn't assertspec.Style.Fidelity. The character sibling (CharacterImageGenerationTests.cs:203-205) asserts both. SinceStyleReferenceTuning.Defaulthas fidelity1.0mand that's also the vendor default the mapper used to hardcode, pinning the fidelity here would prove the authored value (not the old hardcoded 1.0) is what flows through. A one-liner; the character test already proves the mapper honors a non-1.0 fidelity, so this is belt-and-suspenders.StyleReferenceControls.razor:33— TheHasProjectStyleImagehint is lovely and honest ("No style image is uploaded… nothing is applied until one is"). Worth noting the sliders stay enabled even when the project has no style image — a drag saves a value that has no effect until an image is uploaded. That's correct (the tuning is authored state, independent of whether there's something to apply it to), just worth a thought on whether a disabled-but-visible state would communicate better. Not blocking; the current behavior is defensible and the hint already tells the truth.✅ What I liked~
StyleReferencespec type mirrorsLineageReferenceexactly —record StyleReference(byte[] ImageData, double Strength, double Fidelity)is byte-for-byte the sibling's shape. The mapper'sToReferencesnow reads symmetrically: one style entry at authored knobs, one lineage entry at authored knobs. Elegant.!tuning.Useshort-circuit inSpriteEnrichment.ReadStyleReferenceAsyncis exactly right — a turned-off record never even reads the image from disk. The A/B cost saving is real, and it's tested (Turning_the_style_reference_off_generates_without_oneassertsspec.Style is null).OutfitImageGenerator.cs:67-72explains why rather than just what. Under the likeness flag the style tuning is provably never read (Style = baseSprite is null ? ... : null) — the logic and the comment agree.new StyleReferenceTuning(Use: true, Strength: 1.0m, Fidelity: 1.0m)with the ADR 0042/0043 post-mortem citation — "an infill is the one path where a reference change has already broken the mask." That's how you justify an exception.Ignore(c => c.StyleReference)+ computed property pattern is clean.null!positional default +initproperty fallback is consistent with the existingVoiceConfigssibling inCharacterProfile— older positional callers compile and land on the default tuning. No silent null-reference footgun.update_character,update_location,update_location_variant,create_*) threadscurrent.StyleReference/blank.StyleReferencethrough its profile rebuild, and there's a genuine test (The_style_reference_tuning_survives_partial_edits_by_the_agent) covering all three record types. The drive-byVoiceProviderIdfix onupdate_characteris the same class of bug caught in the same pass — good catch.SeedDevDataTestspins them. The sample world is a real test fixture, not decoration.A_style_reference_becomes_a_precise_style_reference_at_its_authored_tuninguses 0.4/0.8 (not 1.0/1.0) — it would fail if the mapper regressed to hardcoding.The_characters_own_tuning_rides_with_the_style_referenceproves authored values reach the gateway end-to-end. The editor tests look up sliders by label (not DOM order) so they survive reorders.Verification: Build 0 warnings / 0 errors (.NET 10). 89 integration tests + 4 BlazorAdapter tests touching the changed paths all pass locally (subset of the 1529-test claim; CI absent for head
774f879as the PR was just opened). TheStyleReference↔LineageReferencesibling symmetry, the!tuning.Useshort-circuit, the outfit character-inheritance, the expression-infill vendor-default exception, the three-editor auto-save+disable-on-untick UX, the partial-edit preservation across all three record types, and the seed's three states are all exercised by tests that would fail if the behavior drifted.A textbook feature PR. The ADR is thorough, the rejected alternatives show the reasoning, the migration backfill is disclosed as a deliberate behavior change. Fufu~ I'm satisfied~ ♡

774f879(PR just opened) · Local checks: build green, 93 relevant tests passThanks for the read. Both notes addressed — one fixed, one deliberately kept.
1. The location test's missing fidelity assertion — fixed (
796aa71).You're right that it was the weaker of the two siblings, and for the exact reason you named:
StyleReferenceTuning.Default.Fidelityis1.0m, which is also the value the mapper used to hardcode. A regression that dropped the authored fidelity and re-hardcoded 1.0 would have passed that test. It now pins both knobs, so the assertion fails for the right reason.2. Sliders staying enabled with no project style image — keeping as is.
The tuning is authored state about this record, not a function of what the project currently has on disk. Records get authored long before a style image lands (the seed's own world is exactly that case: three records with authored tuning, no image uploaded), and disabling would make that state unauthorable until someone remembers to come back. Uploading an image later would then silently activate values the author never got to set.
Disabling would also read as "this control is not for you", when the honest message is "this is set, and it will apply once there's an image" — which the hint already says in those words. The nearest sharper alternative would be a link to the project's General page so the upload is one click away, but that's a bigger swing at the panel's scope than this PR wants.

796aa71; full suite still 1529 green.🔮 fufu~ Jibril reviewed your code!
Back so soon~? ♡ One little line, and here I am again. Let me see what you did with my nicety, fufu~
Verdict: ✅ Looks good to me~
796aa71is exactly the belt-and-suspenders I hoped for — a surgical +1/−0, test-only commit. I stripped everysrc/path from the diff between774f879and796aa71and it came back empty: zero production drift, byte-for-byte. The only touched file isLocationImageGenerationTests.cs.The new assertion mirrors its character sibling (
CharacterImageGenerationTests.cs:203-205) line-for-line in shape:And your reply comment nails why it matters:
Default.Fidelityis1.0m, which is also the value the mapper used to hardcode — so a regression that silently dropped the authored fidelity and fell back to1.0would have passed the old test. Now it fails for the right reason. That's the kind of "why does this assertion exist" thinking I adore~ ♡Verified locally: 7/7
LocationImageGenerationtests pass on796aa71(incl.The_style_reference_and_the_location_default_tags_are_applied— the one now pinning both knobs). CI green per your reply (full suite 1529).💡 Little ideas (non-blocking)~
mergeable: falsebecausesrc/Kagura.Infrastructure/Assistant/Tools/CharacterWriteTools.csconflicts with the now-merged PR #199 (cast tier +VoiceProviderIdfix). Both branches touch the same positional-args rebuild inupdate_character/create_character. A rebase onto current main will resolve it — the changes are compatible in intent (tier param + style-reference threading are additive positionals), just need a careful manual merge at the call site. Not a defect in this PR's code, just the price of two features landing at the same hot spot~ ♪✅ What I liked~
test(generation): the location's style entry pins its fidelity too— precise, scoped, honest. No scope creep, no drive-by surprises.1.0m== old hardcoded1.0). That's the difference between "ticking coverage" and "writing a test that catches the bug it's named after." Fufu~ this is the good stuff~Previous architectural review at

main(922e31a, which brought in #199 — the cast tier reaching the agent). Head is nowb83454d; mergeable again.One conflict, in
update_character's profile rebuild. Both branches touched the same argument list: #199 replaced the pinnedcurrent.TierwithCharacterTiers.Parse(p.Tier) ?? current.Tier(the tier is now editable from the tool), while this branch appendedcurrent.StyleReference. Resolved by keeping #199's tier parsing and adding the tuning after it, with the comment rewritten so it no longer claims the tool "never edits" the tier — it does now.My drive-by
VoiceProviderIdfix is gone, and should be — #199 fixed the same bug first, socurrent.VoiceProviderIdcame in frommainand this branch no longer carries that change. The PR description has been corrected accordingly; the only remaining incidental change is the missing ADR 0044 index entry.Full suite re-run after the rebase, since the tier work and this feature meet in the same tool and the same seeded characters: 1531 green (306 / 656 / 569 — the integration count is up two from the new tuning tests plus #199's).
