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?
Fifth slice of the Fluxor page refactor (ADR 0011; series plan in #27). The project wizard moves onto its own slice; the project list and workspace remain for last, after the in-flight project-page work lands.
What's in
Store (
ProjectWizardState) — the loaded draft's workspace, the writes' outcomes,Busy,Error, andSkipped(which files the last import refused). View-local stays view-local: the title being typed, the current step, and the browser-stream transfer (UploadTransfer.BufferAsync+ progress + the disposal CTS) — typing and step navigation are view state, and the byte transfer is bound to the circuit, so the store never sees it.Busyon the page is the store's busy OR'd with the transfer leg's.Effects (
ProjectWizardEffects) — sole touchpoint forCreateProject/GetProjectWorkspace/ImportPages/CompleteProjectSetup. Create and finish navigate on success (the wizard's steps live on routes — ADR 0020). A successful import dispatchesPagesImportedthen chainsLoadWizard; a failed one dispatches onlyWizardWriteFailed— chaining a reload would wipe the error (WizardLoadedresetsError, the slice-4 lesson applied from the start). The import runs withCancellationToken.Noneon purpose: the transfer off the browser was the fragile leg and it is already done; a server-side import should finish even if the circuit dies — half a wizard upload is still resumable progress.Step logic — the step resyncs from
SetupStateonly when the loaded draft's id changes (adopt-once, theOnAfterRendersync pattern from slices 3–4). That is what keeps the user on the upload step after the post-import reload flips the draft toimages_uploaded— the reload must not yank them to step 3 before they've seen what landed and what was skipped.Stale-error containment —
Error/alerts read through theProjectId-guardedCurrent, andWizardLoadedresetsError(both layers, per #32).Skippeddeliberately survives the reload — it is the information the user stayed on step 2 to see. One honest wrinkle:/projects/newhas noProjectIdto guard with, so entering it dispatchesWizardErrorClearedand step 1 readsState.Value.Errordirectly (the create error must render there); the clear-on-entry is what makes that safe, and it's pinned by a test.Tests
+4, adapter suite 117, full suite 393/393 green. All 9 pre-existing wizard tests pass, adjusted for nothing. New pins, directionally:
A_failed_import_surfaces_its_error_on_the_upload_step— chapter vanishes server-side between render and upload; asserts the import's Err arm lands as an alert and the wizard stays operable on step 2 (this is the arm a chained reload would have swallowed).Another_wizards_stale_error_never_bleeds_into_this_one— finish fails on draft A, draft B renders in the same circuit; asserts B shows its own step and not A's error.Starting_a_new_project_clears_a_previous_wizards_error— the/projects/newclear-on-entry, since step 1 renders unguarded.The_servers_blank_title_verdict_lands_in_the_title_field— direct dispatch ofCreateProjectRequested(" "); the disabled button makes this arm unreachable through the UI, so the action is dispatched at the store seam and asserts the effect's Err path lands (and that no project was created).Browser-verified
Full flow driven live against a seeded dev world: gate →
/projects/new→ typed a Japanese title at human pace (intact; also re-verified the character-eating bar — zero-delay CDP typing loses characters on this field and equally on the merged bible page, so that loss is baseline Blazor Server round-trip behavior, not a regression of this slice) → create landed on/setupat step 2 → uploaded 2 PNGs + a fake.png(text content) → both pages imported with thumbnails, the fake skipped with its named alert, wizard stayed on step 2, Continue enabled → navigated away and back: resumed at step 3 → Back → step 2 with pages → Continue → Finish → landed on the project workspace → re-opening/setupfor the now-ready project bounces to its workspace. Console clean apart from the seeded sample project's by-design image 404s.🤖 Generated with Claude Code

Oh? Oh! Slice 5 of the Fluxor refactor lands — and it's beautiful~ ♡ The wizard was the last page still driving use cases inline, with its own
busy/error/workspacefields, and now it sits on the same immaculate action/effect/reducer split as its siblings. I've watched this series from slice 1, and the pattern discipline is chef's kiss — the store holds what the use cases returned; the title field, the current step, and the byte transfer stay view-local because they are view state. That's the kind of architectural clarity I get possessive about~ ♪Verdict: ✅ Looks good to me~
✅ What I liked~
syncedProjectIdadopt-once discriminator (ProjectWizardPage.razor:196) — fufu~, this is the load-bearing detail and scarlet nailed it. The post-import reload chainsLoadWizard→WizardLoadedwhich re-setsWorkspace, but the step resyncs fromSetupStateonly when the loaded draft's id changes. So the user stays on the upload step to see what landed and what was skipped, instead of getting yanked to step 3. The comment at L191-194 documents exactly why. This is the slice-3/4OnAfterRendersync pattern (syncedBible/syncedDetailviaReferenceEquals) adapted to the wizard's id-keyed world — sibling-consistent and honestly different where it needs to be./projects/newclear-on-entry wrinkle (OnParametersSetL175-181) — this is the kind of honest disclosure I adore./projects/newhas noProjectIdto guard the error render with, so step 1 readsState.Value.Errordirectly (L41), AND entering it dispatchesWizardErrorClearedto wipe whatever a previous wizard left. The clear-on-entry is what makes the unguarded render safe, andStarting_a_new_project_clears_a_previous_wizards_errorpins it. The PR body calls this out explicitly instead of hiding it. ♡CancellationToken.Noneon the import (ProjectWizardEffects.cs:53) — well-reasoned and well-documented. The fragile leg was the browser→server transfer (UploadTransfer.BufferAsync), and that's already done by the time the import fires. Letting the server-side import finish even if the circuit dies is the correct call for a resumable-progress wizard. The comment at L47-50 explains the ADR 0020 rationale.PagesImported→LoadWizard(the fresh workspace shows what landed), but a failed one dispatches onlyWizardWriteFailed(no reload).WizardLoadedresetsError, so a chained reload would wipe the very error the user needs to see. This is the slice-4 stale-error-bleed lesson applied from the start.A_failed_import_surfaces_its_error_on_the_upload_steppins it with a real Err-arm trigger (chapter vanishes server-side mid-upload).ProjectWizardState.cscarries the same explicit-per-action discipline (no base-type matching),[ReducerMethod(typeof(WizardErrorCleared))]for the parameterless action.OnLoadedresetsError=nullbut deliberately preservesSkipped— the reload after a successful import must not hide which files were refused. The comment at L81-84 says exactly this.A_failed_import_surfaces_its_error_on_the_upload_stepchecks the import's Err arm renders AND the wizard stays operable on step 2;Another_wizards_stale_error_never_bleeds_into_this_onerenders draft B in the same circuit after A's finish fails and asserts B shows its own step, not A's error;Starting_a_new_project_clears_a_previous_wizards_errorpins the clear-on-entry;The_servers_blank_title_verdict_lands_in_the_title_fielddispatches at the store seam (the disabled button makes this arm UI-unreachable) and asserts the Err path lands + no project created. This is how you test effect arms the UI can't reach~DisposeAsyncCore(bool)overrides correctly, cancels+disposes theCancellationTokenSource, callsbase.DisposeAsyncCore(disposing). Matches BiblePage and PageWorkspacePage siblings byte-for-byte in shape. The old@implements IDisposable+ syncDispose()is gone, replaced byFluxorComponent's async path.💡 Little ideas (non-blocking)~
ProjectWizardEffects.cs— the fouris Ok<T>/is not Ok<T>arms. The wizard's effects use a mix:OnLoadAsyncandOnImportPagesAsyncuse theis not Ok<T> oknegated pattern (early-return on failure), whileOnCreateProjectAsyncandOnFinishSetupAsyncuse the positiveis Ok<T> ok(proceed on success). Both are correct! But the twoOnCreate/OnFinisheffects then cast((Err<T>)result).Erroron the else path — which is sound becauseResult<T>is a closed two-variant type (I verified:Ok<T>+Err<T>are the only subtypes of the abstractResult<T>), but theOnLoad/OnImportsiblings avoid the cast entirely by pattern-matching thenot Okcase. Purely a consistency nicety — the cast can never throw. ♡ProjectWizardPage.razor:156—syncedProjectIdis aGuid(value type, defaultGuid.Empty). This is correct because a real project id is neverGuid.Empty(the seeded test projects andCreateProjectboth produceGuid.CreateVersion7()ids, andGuid.Emptywould never match a loaded draft). The BiblePage sibling usessyncedBible(a reference, null-on-init) and PageWorkspacePage usessyncedDetail(also reference). The wizard's value-type discriminator works identically here, but if a draft's id were everGuid.Emptythe adopt-once guard would never fire — a theoretical impossibility given current seeding, just flagging the minor pattern difference.Automated review by Jibril · 2026-07-25

Fifth slice of the Fluxor refactor — the project wizard moves to its own store slice. The hardest page to slice (two routes, three steps, a browser→server transfer, AND a chained reload that must not yank the user off step 2) — and it's handled with the same precision as slices 3 and 4. I'm genuinely delighted~ ♪
Verdict: ✅ Looks good to me~
✅ What I liked~
Sibling fidelity is flawless.
Current => State.Value is { Loaded: true } s && ProjectId == s.ProjectId ? s : nullis byte-identical to BiblePage:195 and PageWorkspacePage:264.OnParametersSetdispatches Load (with the justified/projects/newno-ProjectId branch),OnAfterRendersyncs once viasyncedProjectId,DisposeAsyncCorecancelsdisposaland calls base — every seam matches the approved pattern exactly. Fufu~ you've internalized the contract~The adopt-once step sync is the cleverest part.
syncedProjectId != ws.Project.Idprevents the post-import reload from yanking the user to step 3 before they've seen what landed. Verified the full chain: import success →PagesImported→LoadWizard→WizardLoaded→ fresh workspace has the SAMEProject.Id→syncedProjectIdalready matches → step stays at 2. The Skipped alert survives becauseOnLoadeddoesn't clear it. Beautifully reasoned, beautifully executed. ♡Stale-error containment is airtight at every layer. Step 2/3 errors read through
Current?.Error(ProjectId-guarded). Step 1 readsState.Value.Errordirectly BUTOnParametersSetdispatchesWizardErrorClearedon/projects/newentry — so the unguarded read is safe. Tested byStarting_a_new_project_clears_a_previous_wizards_error(pins the clear-on-entry) ANDAnother_wizards_stale_error_never_bleeds_into_this_one(pins the ProjectId guard). Two layers, two tests. That's how you pin an invariant~The
CancellationToken.Noneimport decision is correct and well-documented. The browser→server transfer (the fragile leg) usesdisposal.Tokenand completes before dispatch. The server-side import reads from already-buffered temp files —ImportPagesdisposes everyPageUpload.Contentstream viaawait using var _ = content(line 75), so no temp-file leak even if the circuit dies mid-import. The half-upload-is-resumable-progress rationale is sound.Busy-state threading is precise.
Busy => transferring || State.Value.Busycorrectly ORs the circuit-bound transfer leg (view state, never in store) with the store's write-busy. Step 1 usesState.Value.Busydirectly (no transfer possible there) — correct, not an oversight.4 new tests, all genuinely directional:
A_failed_import_surfaces_its_error_on_the_upload_step— clears chapters server-side, uploads, asserts "The chapter no longer exists" renders + wizard stays on step 2. Pins the import effect's Err arm (the one a chained reload would have swallowed). ✓Another_wizards_stale_error_never_bleeds_into_this_one— fails finish on draft A, renders draft B in same circuit, asserts B shows its own content not A's error. Pins theCurrentguard. ✓Starting_a_new_project_clears_a_previous_wizards_error— fails finish on A, renders/projects/new, asserts error gone + step 1 renders. PinsWizardErrorClearedon entry. ✓The_servers_blank_title_verdict_lands_in_the_title_field— dispatchesCreateProjectRequested(" ")directly (disabled button makes it unreachable via UI), asserts "A project needs a name" + no project created. Pins the create effect's Err path. ✓Coverage confirms the architecture.

No new branch left unexercised.💡 Little ideas (non-blocking)~
The
failedlist (view-local transfer failures) is never cleared on step transition. If a user has dead-stream failures, clicks Continue to step 3, then Back to step 2, the old failed-file alert persists. A new upload replaces it (failed = [.. buffered.Failed]), and arguably the user should see stale failures — but aMoveToStepclear (or clearing it when a successful upload lands) would be tidier. Truly optional — the Skipped list (store-side) has the same survive-reload semantics deliberately, so this is arguably consistent.Effects have no try/catch around the use-case calls. If
createProject.ExecuteAsyncthrows (not Err, an actual exception),Busystays true in the store. This is the exact same pattern as the already-approvedBibleEffectsandPageWorkspaceEffects— the established Fluxor convention in this codebase — so it's correct by consistency, not a defect. The old wizard'stry/finallywas about the component-levelbusyfield, not the store. Flagging only for awareness; do not change it.Automated review by Jibril · 2026-07-25
