The bool Comment on CircleAuthorizationToBlogPost was dead code:
never read or written by any caller in src/, no UI exposure, no
behavioural semantics. The wire DTO (CircleAuthorization in
Yavsc.Abstract) doesn't carry it, no reader consumes it, and the
PostIt client builds its payload without it.
What changes:
- src/Yavsc.Server/Models/Access/CircleAuthorizationToBlogPost.cs:
remove the property.
- src/Yavsc.Blogs.Tests/BlogAclApiTests.cs: drop 'Comment = true'
from the existing test payload and trim the now-inaccurate XML
doc comment ('CircleId + BlogPostId + Comment' -> 'CircleId +
BlogPostId'). Also adds a new [Fact] pinning the prod bug
reported on 2026-08-21 (HTTP 500 'BlogPostId is unknown' when
PostIt POSTs the bare { circleId } shape). That test stays red:
the real fix for the 500 is in PostIt (payload needs blogPostId)
+ on the wire DTO + server-side validation, and lives in a
follow-up commit.
Migration:
- src/Yavsc.Org/Migrations/20260820232152_DropCommentFromCircleAuthorizationToBlogPost
drops the boolean 'Comment' column on CircleAuthorizationToBlogPost.
The generated scaffold also wanted to drop three 'ClientId1'
shadow FK columns on ClientScopes / ClientRedirectUris /
ClientGrantTypes (from leftover HasOne<Client>() overrides in
ApplicationDbContext.OnModelCreating); those were removed from
the .cs to keep the migration scoped to this fix. Cleaning up the
shadow property declarations themselves is left as a separate
task.
The ModelSnapshot still reflects the shadow 'ClientId1' columns
intentionally: they exist in the prod database today (all NULL),
and EF will rescaffold a drop migration for them on the next
'migrations add' regardless. No data loss.

PostIt UI for circles + per-post ACL
- Reorganise PostIt.Tests into Auth/ and Blogs/ subfolders
(Bearer/OIDC scope tests vs. blog API fakes live where they
belong) and introduces PostItHeadlessCollection so the
Avalonia.Headless tests share a single xUnit collection
instead of contending with the EF-Core test host.
- Adds BlogAclApiTests (a brand-new behavioural layer over
POST /api/v1/blogacl) and the fakes it relies on
(BlogApiTestFakes, BlogPostAuthorDtoTests, AddCircleMember
DialogTests); pulls UserId-through-OIDC-sub path into
BearerScopeTests / FakeAuthorizingBrowser /
OidcStubAuthority.
- App.axaml.cs gets a small PushPageAsync touch-up the new
tests rely on.
- Drops UnitTest1.cs (xUnit scaffold, never used).
Yavsc.Blogs.Tests — SQLite instead of InMemory
- Bumps Yavsc.Blogs.Tests.csproj on
Microsoft.EntityFrameworkCore.Sqlite and rewrites
BlogsWebServerFixture to hold a single shared
SqliteConnection (Cache=Shared) for the fixture lifetime,
with a sync Dispose close to dodge async teardown hangs.
Reason: the EF Core InMemory provider silently ignores FKs,
which masked the kind of bug we are about to pin in the
ACL tests. SQLite enforces them, so any future INSERT that
forgets to seed its parent rows fails loudly here instead
of passing the test and breaking prod.
- PublishEndpointTests and BlogApiSmokeTests get a one-line
tweak to follow the new connection lifecycle.
Foreign-key fallout: seed the default user in the fixture
- Adds BlogsWebServerFixture.SeedUser(userName). Now that
SQLite enforces BlogPost.AuthorId → AspNetUsers.Id, every
test that POST/PUT/DELETE a BlogPost and sends AuthorId=
'tester' in the payload needs an AspNetUsers row to satisfy
the FK or it returns 500 with SQLite Error 19.
- BlogApiTests wraps the existing ResetDatabase with a
ResetAndSeedDefaultUser helper for the six mutating tests;
the four GET-only and ModelState-only tests keep the bare
ResetDatabase.
- Side benefit: every test in Yavsc.Blogs.Tests now finishes
cleanly instead of hanging at teardown — previously a stuck
test held the shared SqliteConnection open and the next
tests waited indefinitely.
Verified: dotnet test src/Yavsc.Blogs.Tests passes 25/25
green from a clean run, no fixture teardown hang.
- CirclesPage: drop VisualRoot/MainWindow hack, switch to App.PushPageAsync(vm)
- CirclesPageViewModel: make OpenAddMemberAsync public so Avalonia XAML trampoline can call it
- AddCircleMemberDialog: bind SearchAsync/Add (drop Command suffix)
- UserSearchApiController: route under Constants.APIPrefix (= api/v1/user-search), matching the rest of Yavsc.Blogs controllers and the PostIt client's BlogsApiUrl default
The 'Navigation (PostIt)' rule was buried as a sub-item under
'Conventions de code', mixed with style rules. Lift it to a
top-level section between 'Tests' and 'Conventions de code' so
contributors looking for nav guidance find it without scrolling
through editorconfig preferences.
Add a pointer to doc/architecture/postit.md for the full
topology (NavRoot, SessionStatusViewModel, lifecycle signals
vs user-driven nav). Content of the rule itself is unchanged
from 12a71ada — only the placement and the cross-link.
The two recent commits (3fbbafc4, 0065de70) replaced the
OpenSettingsRequested event + CurrentViewModel assignment with
App.PushPageAsync(vm): the VM resolves the target ViewModel
through DI, App resolves the Control through the ViewLocator,
guards against double-push, and pushes via NavRoot. The docs
were still describing the pre-refactor world.
Update three places:
- CONTRIBUTING.md — the "Navigation (PostIt)" rule now
describes App.PushPageAsync as the single channel and shows
the canonical OpenSettings command as the example.
- doc/architecture/postit.md — the Navigation section
distinguishes VM-first navigation (App.PushPageAsync) from
lifecycle signals (LoginSucceeded, LogoutCompleted) and
drops the obsolete OpenSettingsRequested row.
- src/PostIt/PostIt/App.axaml.cs — refresh the SettingsPage
singleton justification: point (c) now describes the
anti-empilement guard inside PushPageAsync, not the
OpenSettingsRequested handler that no longer exists.
No production behaviour change — doc only (and the inline
comment that referenced a removed event).
Navigation in PostIt is owned by src/PostIt/PostIt/ViewLocator.cs.
To open a screen, the caller assigns the target ViewModel to the
host's CurrentViewModel (which binds the IContentControl.Content);
the ViewLocator decides which Control instance to push and resolves
it through DI. ViewModels never instantiate views nor resolve them
from DI directly. Add the rule and a canonical example to
CONTRIBUTING.md so contributors do not re-derive the pattern from
scratch each time.
Three buttons on MainPage's toolbar are reported as inoperative
in the running app: ACL, Mes cercles, and [DEV] Signature. They
click but no dialog / page opens.
This commit adds headless UI tests that drive each button via
the Avalonia headless harness (KeyPressQwerty(Enter) on a
focused, x:Name'd button, per the CalculatorTests pattern in
Avalonia.Samples) and asserts the post-click top of
NavRoot.NavigationStack is a non-null Page.
The tests fail today on every button (stack size before == after
== 1): the click does not push anything. The bug is the user's
real complaint — the test is now wired to catch it.
To make the buttons reachable by the harness without walking
the visual tree (which does not see buttons hosted inside a
NavigationPage), name the two unnamed buttons:
- ACL -> ManageAclButton
- Mes cercles -> OpenCirclesButton
([DEV] Signature was already named OpenSignatureDevButton.)
The XAML change is cosmetic; bindings and commands are
untouched. The test pattern follows SessionStatusBannerTests:
new MainWindow().Show(), PushAsync(MainPage), drive controls via
their generated x:Name fields.
System.Text.Json cannot materialise an interface without a
polymorphic converter. Until this commit, BlogPostDto.Author
was typed as the abstract interface IApplicationUser, which
crashed the "load posts" call in PostIt whenever the server
returned a post with a populated Author object (the common
case — GET /api/BlogApi).
Fix:
* Introduce a minimum-viable wire DTO BlogPostAuthorDto in
Yavsc.Abstract.Blogspot (record: Id, UserName, Avatar).
These are the only fields the client UI actually needs;
the server-side ApplicationUser navigation is preserved
for permission checks and authorisation.
* Change IBlogPost.Author and BlogPostDto.Author from
IApplicationUser to BlogPostAuthorDto? (interface change,
breaking). The EF entity BlogPost keeps its full
ApplicationUser navigation property and exposes
IBlogPost.Author via an explicit interface implementation
that projects to BlogPostAuthorDto on demand (so EF can
still lazy-load the navigation without forcing an eager
join on every read).
* Restore the using directive that was accidentally removed
when the BlogPostDto property was rewritten (needed for
ICircleAuthorization in GetACL()).
Regression coverage (the missing test Paul flagged):
* Add BlogPostAuthorDtoTests in PostIt.Tests with four
scenarios that exercise the wire shape on the client side:
- A BlogPostDto JSON with a populated Author round-trips
through JsonSerializer without throwing and the three
fields (Id, UserName, Avatar) survive intact.
- A BlogPostDto JSON with explicit "author": null
deserialises with Author == null.
- A BlogPostDto JSON without any Author field at all
deserialises with Author == null (forward compat).
- The serialised shape of BlogPostAuthorDto uses camelCase
property names (matching the server's Web defaults), so
the field names on the wire don't drift without a test
catching it.
Tests: 55/55 PostIt.Tests (+4 new), 24/24 Yavsc.Blogs.Tests,
44/44 Yavsc.Org.Tests. No regressions.
Side note: yavsc.sln picks up Yavsc.Api.Client (added by
'feat/postit-acl' in 1.0.7 but never registered in the
solution file until now — probably auto-added by a recent
'dotnet build' that discovered the .csproj).
PR #37 (feat/postit-fs -> release/1.0.8-rc1) was opened before
the buildAndTest.yml workflow trigger was widened to include
release/*. Forgejo Actions does not re-evaluate the workflow
file on its own — a push event on the PR is needed to
re-trigger the CI. This empty commit is the push.
The release workflow's validate-release job requires a
'## [TAG] - channel' section in CHANGELOG.md before allowing
the tag to ship. Without this entry, the 1.0.7 tag push
fails the workflow with:
::error::No section matching '## [1.0.7]' found in CHANGELOG.md.
Add a '## [1.0.7] - preview' section before tagging.
The section collects the 35 commits shipped between 1.0.6 and
1.0.7: ACL feature (per-post grants + circle membership), the
Publish toggle that replaces the abandoned Visibility enum,
the make release target, the IYavscApiClient abstraction, the
IContactService/IUserDirectory split, and the Forgejo Actions
release workflow rewrite (bash + jq, runner-provided
GITHUB_TOKEN, .csproj projects built directly inside the
runner container).
The '## [Unreleased]' block is consumed by this section, and
the trailing link reference is updated to point at
1.0.6...1.0.7 for the standard Keep-a-Changelog compare URL.
Paul wanted a Makefile target that:
- takes the target version as an argument (V=1.0.7-rc1),
- creates a release/<V> branch from main,
- runs 'dotnet-gitversion /updateprojectfiles' to bump
<Version> across all .csproj from git history,
- commits the bump on the release branch (not on main, so
main stays clean),
- pushes the new branch to origin.
The /src/**/*.csproj paths and CHANGELOG.md are excluded from
Forgejo's protected-branch rule so the bump commit goes
through on the release branch.
The target refuses to run unless the operator is already on
main with a clean working tree — no automatic checkout to
main, so the bump never lands on the wrong branch by
accident.
The version in the branch name (V=...) is an intent label.
The version GitVersion writes into the .csproj is whatever
GitVersion computes from git history (last tag + commit
count), so assembly versions stay truthful even when the
branch name is aspirational.
Replaces the previous 'Visibility enum' approach (commit 33ecfa7e,
reverted in 42625f5d) with the existing BlogSpotPublication
mechanism. Paul pointed out that the system already had a
publication table and a Publish field on BlogPostEditViewModel;
we just didn't expose it through the API.
The toggle is its own action on the API surface — a dedicated
endpoint rather than a field on the existing BlogPost wire
DTO. This keeps the BlogPostDto contract unchanged and avoids
shoe-horning 'Publish' into the entity model alongside
Title/Article (where the existing BlogSpotService.Modify
already takes two overloads and a third felt like drift).
Server (Yavsc.Blogs / Yavsc.Server)
- PUT /api/BlogApi/{id}/publish body { publish: bool }
Returns 204 on success, 404 when the post doesn't exist,
Challenge() (401) when the caller is not the author
(EditPermission gate). Idempotent: PUT because the
resulting state matches the body, not the request.
- BlogSpotService.SetPublishAsync(user, postId, publish)
factored out of the existing
Modify(BlogPostEditViewModel) inline toggle, so the new
endpoint reuses the same BlogSpotPublication row logic
(add row if missing on publish=true, remove row if
present on publish=false).
- BlogPost.IsPublished (NotMapped) is now hydrated by the
service after each Index/Details fetch — a single bulk
lookup, not N+1 — and surfaces through the wire JSON
so PostIt can show the current state without a follow-up
request.
- ApplicationUser nav properties (Posts, Book,
DeviceDeclaration, Connections, Circles, BlackList,
Rooms, RoomAccess, Membership, BlogComments) now carry
BOTH [JsonIgnore] (Newtonsoft) and
[System.Text.Json.Serialization.JsonIgnore] so the
Yavsc.Blogs test fixture (System.Text.Json) stops
exploding on object cycles when serialising
BlogPost.Author.Posts.Author.Posts. Production
(Yavsc.Org, NewtonsoftJson) was already safe via the
Newtonsoft-only attribute; this commit just makes the
Yavsc.Blogs side consistent.
Client (Yavsc.Api.Client)
- BlogApiClient.SetPublishAsync(id, publish) → PUT to the
new endpoint.
DTO wire (Yavsc.Abstract.Blogspot.BlogPost)
- BlogPostDto.IsPublished added. Same shape as the entity
field; serialised as a plain bool in JSON.
UI (PostIt)
- MainPageViewModel.DraftIsPublished (ObservableProperty)
mirrors the existing DraftTitle/DraftArticle pattern;
hydrated from SelectedPost.IsPublished on selection
change. TogglePublish command pushes the new state to
SetPublishAsync and updates both the buffer and the
selected post locally so the UI reflects the change
without a full Refresh.
- MainPage.axaml: a CheckBox 'Publié' in the toolbar,
bound to DraftIsPublished TwoWay and wired to
TogglePublishCommand. The toggle is its own action
(not part of Save), matching the wire contract.
Tests (Yavsc.Blogs.Tests)
- PublishEndpointTests (4 [Fact]):
* PUT publish=true returns 204 and IsPublished is true
in the next GET
* PUT publish=false clears IsPublished
* PUT on an unknown post returns 404
* PUT by a non-author does not return 204 (Challenge)
- BlogsWebServerFixture now wires
app.UseDeveloperExceptionPage() so 500s in tests
surface a real stack trace instead of an empty
InternalServerError body — much easier to diagnose
future regressions.
Test totals: 24/24 Yavsc.Blogs.Tests (was 20, +4
PublishEndpoint), 51/51 PostIt.Tests (no change), 44/44
Yavsc.Org.Tests (no change).
Out of scope (tracked in MEMORY.md, 2026-08-18):
- i18n: only the new 'Publié' label is localised; the
rest of MainPage.axaml is still hard-coded French.
- BlogPostEditViewModel.Publish ↔ IsPublished reconciliation
in the admin web Yavsc (the Org UI already edits Publish
inline; no work needed there).
Replace the implicit 'ACL empty = private' convention with an
explicit two-axis model: Visibility is the master switch, the
ACL is the exception list.
Semantics (matches what BlogSpotService.Index / Details enforce):
Visibility.Public + empty ACL : every caller sees it
Visibility.Public + non-empty : only author + ACL circles + admin
Visibility.Private + any ACL : only author + admin (ACL ignored)
ACL is preserved across
Private/Public flips so
reopening is lossless
The Public+non-empty shape is the 'restrict by exception' case:
open by default, narrowed by the ACL. This is intentionally
different from the previous behaviour, where a Public post
with a non-empty ACL was effectively ACL-restricted anyway —
the new model makes that explicit and removes ambiguity.
Server (Yavsc.Blogs / Yavsc.Server)
- New enum Visibility { Private, Public } in
Yavsc.Abstract.Blogspot (so the wire DTO and the EF entity
share the same type). Stored as int via .HasConversion<int>()
on BlogPost.Visibility. Default Private on construction;
the column default in the migration is 0 so existing rows
land Private without any data migration.
- BlogSpotService.Index: filter rewritten to honour the two-
axis model. Authenticated and anonymous callers now share
the same shape (Public+emptyACL visible to all, otherwise
scoped). Admin reads still go through PermissionHandler.
- PermissionHandler.IsPublic: dropped the blogSpotPublications
lookup, replaced with the Visibility + empty-ACL check that
matches the new model. PermissionHandler.IsSponsor and
IsOwner unchanged.
- UserHelpers.UserPosts (the per-author feed for
/CircleMembers/Details and similar): mirror of the
Index filter, so the two code paths can't silently diverge.
- BlogPostEditViewModel.Publish untouched on this commit. It
still controls whether a row exists in BlogSpotPublication;
the two systems coexist (Publish = 'is this draft published',
Visibility = 'who can read it'). Follow-up to consolidate.
EF migration (Yavsc.Org/Migrations/20260818143013_AddBlogPostVisibility)
- Scaffolded by 'dotnet ef migrations add', not hand-edited,
per the repo preference for generated migrations.
- Adds the new Visibility column (int, NOT NULL, default 0).
- Also drops three shadow-state ClientId1 foreign keys and
their indexes/columns on ClientScopes, ClientRedirectUris,
ClientGrantTypes. These shadow FKs were created by EF from
HasOne<Client>().HasForeignKey(e => e.ClientId) mappings
that have long since been removed from
ApplicationDbContext.OnModelCreating, but the snapshot was
never regenerated against the current model. The columns
are nullable ints with no production data, so the drop is
lossless. Without this, EF Core would keep emitting
warnings on every migration add and the model would drift
further from reality.
DTO wire (Yavsc.Abstract.Blogspot.BlogPost)
- Visibility property added to BlogPostDto. System.Text.Json
serialises the enum as its underlying int, so the JSON
shape is a plain number, no JsonConverter needed.
Client UI (PostIt)
- MainPageViewModel: DraftVisibility ObservableProperty
mirroring the existing DraftTitle/DraftArticle pattern.
Initialised to Private so a fresh draft is private by
default. Save command writes the chosen value into the
BlogPostDto payload for both CreatePostAsync and
UpdatePostAsync. OnSelectedPostChanged hydrates the buffer
from the server-supplied value.
- AllVisibilities property on the VM exposes [Private, Public]
in that order, bound by the ComboBox in MainPage.axaml.
- VisibilityLabelConverter (PostIt.Views) maps the enum to
French user-facing labels ('Privé' / 'Public'); registered
in App.axaml as a static resource.
- MainPage.axaml: a new ComboBox row in the editor pane
between Title and Article. Uses the existing 'no hardcoded
Background without Foreground' lesson so dark mode works.
Tests (Yavsc.Blogs.Tests)
- BlogVisibilityTests (5 [Fact]): drive GET /api/v1/blog with
Visibility fixtures seeded directly in the in-memory DB:
* Private + ACL: only the author sees it
* Public + empty ACL: any authenticated caller sees it
* Public + non-empty ACL: caller without ACL membership
does NOT see it
* Private + ACL: ACL is ignored, only the author sees it
* Visibility round-trips through the JSON wire (int 1)
- UserHelpersVisibilityTests (4 [Fact]): exercise the helper
directly so the two code paths (Index filter vs per-author
feed) can't diverge silently. Same fixture, no HTTP.
Test totals: 29/29 Yavsc.Blogs.Tests (was 20, +5 BlogVisibility
+4 UserHelpersVisibility), 51/51 PostIt.Tests (no change), 44/44
Yavsc.Org.Tests (no change).
Out of scope (tracked in MEMORY.md, 2026-08-18):
- i18n: only the new 'Visibilité :' label is localised; the
rest of MainPage.axaml is still hard-coded French.
- BlogPostEditViewModel.Publish ↔ Visibility consolidation
(which system wins when both are set on the same post?).
- Org-side UI for editing Visibility (the admin web Yavsc
still edits posts without a visibility field).
Round-trip out a long-standing hole in the ACL feature: until
this commit a circle on Yavsc was an empty named bucket. You
could create 'Famille' and grant it on a post, but the circle
carried no members, so 'Famille' authorised no one. The MVC
admin controller (Yavsc.Org.Controllers.CircleMembersController)
existed but had no REST counterpart, so PostIt — which only
talks to the Yavsc.Blogs API — had no way to manage membership
at all.
This commit closes that gap end-to-end:
Server (Yavsc.Blogs)
- GET /api/circle/{id}/members list members
- POST /api/circle/{id}/members add a user (body { userId })
- DELETE /api/circle/{id}/members/{userId} remove a user
All three are scoped to caller == circle.OwnerId; non-owned
circles return 404 (not 403) to avoid leaking existence, in
line with the rest of the controller.
- Two new DTOs (CircleMemberDto, AddCircleMemberDto) for the
wire shapes. CircleMemberDto mirrors UserSearchResultDto
minus Email — membership UI doesn't need contact details.
Tests (Yavsc.Blogs.Tests)
- CircleMembersApiTests: 5 [Fact] covering empty list,
add+get, duplicate add → 409, remove, and cross-owner 404.
Test users (alice, bob) are seeded directly through the
in-memory DbContext — the Blogs fixture doesn't stand up
UserManager<ApplicationUser>.
Client (Yavsc.Api.Client)
- CircleMemberDto + 3 methods on CircleApiClient:
GetMembersAsync, AddMemberAsync, RemoveMemberAsync.
All match the server's contract: 404 flattens to null,
409 surfaces as an exception (callers can dedupe beforehand
if they want idempotent behaviour).
UI (PostIt)
- CirclesPageViewModel gains a Members ObservableCollection
that auto-loads on SelectedCircle change (via the partial
setter generated by [ObservableProperty]). Commands:
LoadMembersAsync, OpenAddMember (raises an event the view
subscribes to), OnAddMemberConfirmedAsync (called by the
view when the dialog confirms a selection), RemoveMemberAsync.
409 (already a member) is detected from the exception
message and surfaced as a friendly status rather than an
error — a likely race when the same user gets added twice
through two UI paths.
- CirclesPage layout is now two-pane (circles + editor on the
left, members of the selected circle on the right). The
member pane has an 'Ajouter un membre' button that opens
AddCircleMemberDialog. Code-behind wires the dialog's
Confirmed event back into the VM via an async lambda
wrapper (EventHandler<T> wants void, the VM method is
async Task).
- AddCircleMemberDialog is a ContentPage (light modal, same
pattern as PostAclDialog). Its ViewModel consumes
IUserDirectory — the abstraction introduced by 04a31709
to fix the 'user search should not be IContactService'
confusion. The dialog raises Confirmed with the picked
UserSummary; the host (CirclesPage) is responsible for
calling CircleApiClient.AddMemberAsync.
Out of scope (tracked in MEMORY.md, 2026-08-18):
- i18n: all visible text still hard-coded French.
- XAML accessibility audit of pre-existing pages.
- Avalonia.Headless UI tests of the new navigation flow.
Tests: 51/51 PostIt.Tests green, 20/20 Yavsc.Blogs.Tests
green (was 15; +5 for CircleMembersApiTests), 44/44
Yavsc.Org.Tests green (no regression).
The scoping that landed in e376aed8 ("restrict Circle + BlogAcl
reads and writes to caller's own data") reads the caller's uid
with User.FindFirstValue(ClaimTypes.NameIdentifier). That works
when the JWT bearer middleware remaps the "sub" claim to the
long ClaimTypes.NameIdentifier URI — which is the default
behaviour. But the BlogsWebServerFixture test host and any host
that sets MapInboundClaims = false (preserved here to keep
"sub" as "sub" for the resource-based ownership checks in
BlogSpotService) end up with no ClaimTypes.NameIdentifier claim
at all, only "sub". On those hosts, every OwnerId == uid
filter silently returns nothing, so the controller responds 404
even for the caller's own circles.
Switch to the canonical User.GetUserId() extension helper
(Yavsc.Server.Helpers.UserHelpers), which tries "sub" first,
then ClaimTypes.NameIdentifier, then "nameid". This aligns
CircleApiController with BlogApiController (which already uses
GetUserId()) and restores correct behaviour on hosts that run
with MapInboundClaims = false.
Drop the now-unused System.Security.Claims using.
No behavioural change for production: there, MapInboundClaims
remains true, ClaimTypes.NameIdentifier is populated, and
GetUserId() returns the same value as FindFirstValue would have.
IContactService used to be the catch-all for "people you can reach
from PostIt": on mobile it read the device-local address book, on
desktop it queried the central /api/user-search endpoint and merged
both worlds into a single ContactDto (a flat Email field, an
ObservableCollection cache, a SearchAsync method). Two unrelated
flows under the same name, with a wire shape (Email) silently
flattening the mobile provider's multi-email list.
Split into two interfaces, each with a single responsibility:
- IContactService: device-local address book only. Mobile provider
reads MAUI Essentials Contacts.Default and carries the full email
list per contact. Desktop provider is an honest stub returning an
empty list — the desktop has no local address book, and inviting
external people from desktop is a separate flow (manual email
entry + invitation endpoint) that doesn't belong here.
- IUserDirectory: central Yavsc user directory, the only consumer
of /api/user-search. Both Desktop and Mobile providers delegate
to UserSearchClient; the platform split exists so future
platform-specific sources (offline cache, directory-scoped
providers) can plug in without disturbing consumers.
ContactDto restores IReadOnlyList<string> Emails (the flat Email
from d0e0f4c1 was a regression that matched the wire shape of
/api/user-search at the cost of the mobile provider's per-contact
list). UserSummary is a separate platform-neutral record that
mirrors the server's UserSearchResultDto without leaking transport
concerns.
App.axaml.cs registers both interfaces as singletons.
Build + 51/51 PostIt.Tests green. No UI consumer yet — these
interfaces are still plomberie; the ViewModel that joins them for
the "add to a circle" / "invite someone" flows is a follow-up.
