fix(merge): unresolved conflicts compose to empty, not Ours (+ review nits)

Code-review follow-ups before push:
- MergeFile.ResultText/Compose() fell back to Ours for unresolved conflicts while
  the editor seeds them empty — align both on empty so the public model matches the
  pane and Continue can't silently auto-accept Ours.
- Bound the gutter re-layout retry (was an unbounded Background re-post when the
  editor isn't laid out, e.g. minimized).
- Pluralize the readout ('1 conflict' not '1 conflicts'). Tests updated. Ui 128 green.

+# ClaudeDo Online Inbox — API Contract & VPS build prompt
+
+Status: handoff doc. The **server side** (API + minimal web client) is built and deployed
+VPS-side by a separate Claude instance. This file is the source of truth for the contract
+both ends implement against. The desktop client in this repo is built to match it.
+
+---
+
+## 1. Concept
+
+ClaudeDo is a local desktop app that runs tasks autonomously via the Claude CLI; it is
+normally fully local (SQLite). The **Online Inbox** is an optional service that lets the
+single owner view their task lists and add new tasks from a phone/browser. The desktop app
+syncs against it.
+
+**Governing rule:** the online store mirrors EXACTLY the desktop's `Idle` backlog — nothing
+else. A task is present online only while it is `Idle` on the desktop. The moment the user
+queues it locally, the desktop removes it from the online store. Running / WaitingForReview /
+Done / Failed / Cancelled tasks never appear online.
+
+Sync directions (each one-way per entity → no conflict resolution needed):
+
+- **Lists**: desktop → online only. Desktop is the source of truth (full-replace catalog).
+- **Idle tasks**: desktop mirrors its Idle backlog up; the web can create new ones, which the
+  desktop pulls down and then owns.
+
+Single user today. Both the desktop and the web client authenticate as the **same Zitadel
+user**.
+
+**Multi-user readiness (`ownerId`).** Each resource is owned by a Zitadel subject (`sub`).
+`RemoteList`, `RemoteTask`, and `MirrorTask` carry an optional `ownerId` field. The desktop
+stamps its own `sub` (decoded from the access token) onto everything it pushes, and
+defensively ignores any pulled task whose `ownerId` is set to a *different* user; an absent
+`ownerId` is treated as unowned/legacy and still syncs. This keeps the contract ready for
+multiple users **without enforcing isolation client-side** — the server remains the
+authority that scopes every request by the token's `sub`. When the server goes multi-user it
+should partition all rows by owner and ignore (or validate) the client-supplied `ownerId`.
+
+**Access control (as of 2026-06-10).** Access is granted by assigning the **"user" project
+role** in the Zitadel project "ClaudeDo" (id `376787351902355727`, issuer
+`https://auth.kuns.dev`) — there is no app-side allowlist (the former `ALLOWED_USER_IDS`
+env var is gone). The access token carries the role in the claim
+`urn:zitadel:iam:org:project:roles` (or the project-scoped variant
+`urn:zitadel:iam:org:project:376787351902355727:roles`), an object keyed by role key, e.g.
+`{ "user": { "<orgId>": "<orgDomain>" } }`. The desktop OIDC client
+(id `376787352137302287`) has `accessTokenRoleAssertion` enabled, so any token issued
+after login/refresh includes the claim automatically — no extra scopes are needed.
+Granting/revoking access is purely a Zitadel role grant, nothing app-side.
+
+## 2. Idle backlog definition (desktop side)
+
+The desktop mirrors only "real" backlog items, not planning internals:
+
+- `Status == Idle`
+- `ParentTaskId == null` (no planning/improvement children)
+- `PlanningPhase == None`
+- `BlockedByTaskId == null`
+
+## 3. Data model (Postgres)
+
+```
+lists
+  id          text primary key            -- GUID supplied by the desktop; reuse verbatim
+  name        text not null
+  updated_at  timestamptz not null default now()
+
+tasks
+  id          text primary key            -- GUID; SHARED id space (see below)
+  list_id     text not null references lists(id) on delete cascade
+  title       text not null
+  description text
+  imported    boolean not null default false  -- false = web-created, awaiting desktop pull
+                                                -- true  = desktop-owned (mirrored or handed off)
+  created_at  timestamptz not null default now()
+  updated_at  timestamptz not null default now()
+```
+
+**Shared GUID id space.** Web-created tasks get a server-generated GUID; the desktop imports
+under that SAME id, so it never duplicates. Desktop-mirrored tasks arrive with their own GUID.
+All task writes are idempotent upserts keyed on id.
+
+**`imported` flag = ownership.**
+- Web `POST /tasks` inserts `imported=false`.
+- Desktop pulls `imported=false`, creates the task locally (reusing the id), then `POST
+  /tasks/{id}/imported` flips it to `true`. From then on the task belongs to the desktop
+  mirror.
+- `PUT /tasks/mirror` only ever inserts/updates/deletes within the `imported=true` partition.
+  It never touches `imported=false` rows (those are pending handoff).
+
+## 4. Endpoints
+
+All endpoints require a valid Zitadel access token (`Authorization: Bearer <token>`) that
+carries the **"user" project role** (see §1). Missing/invalid/expired token, or a valid
+token without the role → `401`. No anonymous access (imported tasks can trigger code
+execution on the user's machine). The desktop client treats a `401` as: force a
+refresh-token exchange and retry once; if a freshly issued token is still rejected, it
+surfaces "missing 'user' role in Zitadel" and pauses sync until the user signs in again.
+
+> **Auth (VPS/.NET):** use the in-house `KunsZitadel` nuget package (feed
+> `https://git.kuns.dev/api/packages/kuns/nuget/index.json`) — call `AddKunsZitadel(...)`
+> with the Zitadel authority/audience/client id to wire `JwtBearer` validation + CORS for
+> the web client origin. (`KunsZitadel` is server-side token *validation* only; the desktop
+> client acquires tokens via its own OIDC flow.)
+
+| Method & path | Caller | Body | Response |
+|---|---|---|---|
+| `PUT /lists` | desktop | `[{ "id", "name", "ownerId"? }]` — the FULL catalog | `200` |
+| `GET /lists` | web | — | `200 [{ "id", "name", "ownerId"? }]` |
+| `GET /lists/{id}/tasks` | web | — | `200` tasks in that list (`404` if list unknown) |
+| `POST /tasks` | web | `{ "title", "description"?, "listId" }` | `201` created task incl. `id` |
+| `GET /tasks?imported=false` | desktop | — | `200 [{ "id","listId","title","description","createdAt","ownerId"? }]` |
+| `POST /tasks/{id}/imported` | desktop | — | `200` (`404` if unknown) |
+| `PUT /tasks/mirror` | desktop | `[{ "id","listId","title","description","ownerId"? }]` — full Idle set | `200` |
+
+`ownerId` (optional, see §1) is the Zitadel `sub` of the owner. The desktop sends it on push
+and ignores pulled tasks owned by a different user; the server should derive/validate it from
+the token rather than trust the client value.
+
+Semantics:
+
+- **`PUT /lists`** — full replace: upsert all supplied, DELETE any list not in the payload
+  (cascades its tasks). Idempotent.
+- **`POST /tasks`** — `listId` must exist (`400`/`404` otherwise). Server generates the id.
+- **`PUT /tasks/mirror`** — full replace of the `imported=true` partition: upsert every task
+  in the payload (insert with `imported=true`, or update), and DELETE any `imported=true`
+  task whose id is not in the payload. `imported=false` rows are untouched. Idempotent.
+- All task ids are client-trusted within the shared space; the server never rewrites an id.
+
+## 5. Reconcile loop (desktop, runs each poll cycle)
+
+```
+1. PULL:  GET /tasks?imported=false
+          for each: if no local task with that id → create local TaskEntity
+                    { Id = remote.id, ListId = remote.listId, Title, Description,
+                      Status = Idle, CreatedBy = "online" }
+                    (skip + log if remote.listId has no local list)
+                    then POST /tasks/{id}/imported
+2. PUSH LISTS:  PUT /lists  with the full local catalog [{id, name}]
+3. PUSH TASKS:  PUT /tasks/mirror  with the current local Idle backlog set (§2)
+```
+
+Ordering matters: pull+import+flag first, so the just-imported tasks are part of the local
+Idle set computed in step 3 and survive the mirror replace.
+
+## 6. Minimal web client
+
+Integrate into the existing Nuxt app at claudedo.kuns.dev if present; else a minimal page.
+
+- Zitadel login.
+- Show lists (`GET /lists`); select one to see its Idle tasks (`GET /lists/{id}/tasks`).
+- Add-task form → `POST /tasks`.
+- Mobile-first (main use: jotting ideas from a phone).
+- **Create + read only.** No editing, reordering, status changes, or deletes.
+
+## 7. Security
+
+- Every route auth-gated (`401` on bad token); only static assets / login are public.
+- Validate `listId` on task creation; parameterized queries only.
+- CORS restricted to the web client origin.
+- Don't log task titles/descriptions at info level (user content).
+
+## 8. Deliverables from the VPS build
+
+Report back so the desktop can be configured:
+
+1. **API base URL.**
+2. **Zitadel app/client config the desktop must use**: issuer/authority, client id, scopes,
+   and the OAuth flow to use for a desktop app (device-code or auth-code + PKCE), plus how
+   refresh tokens are issued.
+3. Any env vars / README.
+
+Out of scope server-side: task execution (the desktop runs Claude), any task state other
+than the Idle mirror, multi-user / sharing / notifications.

+- **Bewusst zurückgestellt:** WorkerHub-Split nach Concern (~60 Methoden in einer Hub-Klasse). Die Interface-Parität löst das akute Testbarkeits-Problem; ein Hub-Split ist eine größere Architekturentscheidung → erst besprechen.
+- **Lessons learned:** Der `StartRunningAsync`-Guard-Task hat isoliert grün getestet, aber den Queue-Pfad gebrochen (Picker claimt vor dem Dispatch) — Integrationsfix `74ca2e0`. Bei parallelen Tasks, die denselben Pfad berühren, nach JEDEM Merge-Schwung die volle Suite auf main fahren.
+

+
+**Plausibel, noch nicht einzeln verifiziert (bei Gelegenheit prüfen):**
+
+- Cancel eines `WaitingForChildren`-Parents kaskadiert nicht auf laufende/queued Kinder (verwaiste Worktree-Commits).
+- Ketten-Kaskade stoppt an einem `Idle`-Mittelglied (`OnChildFinishedAsync` prüft `CancelAsync`-Ergebnis nicht) → Rest bleibt `Queued+blocked`.
+- Delete des *letzten* nicht-terminalen Kindes triggert kein `TryAdvanceParentAsync` → Parent kann in `WaitingForChildren` hängen (FK `SET NULL` rettet nur die Blocked-Kette).
+- `ContinueMergeAsync` staged per `git add -A` vor dem Konflikt-Check (Marker im Index, Abort danach ggf. unsauber).

 # ToDo-App mit autonomem Agent-Worker — Design
 
+> **Hinweis (2026-06-09):** Historisches Design-Dokument vom Projektstart — bewusst nicht nachgepflegt. Überholt sind insbesondere: die Tag-basierte Queue (entfernt; der Picker nutzt `Status=Queued` + `BlockedByTaskId IS NULL`), `schema.sql` (Schema läuft über EF-Core-Migrations) und das Projektlayout (inzwischen sechs Testprojekte). Lebende Doku sind die `CLAUDE.md`-Dateien pro Projekt.
+
 ## Context
 
 Ziel: eine persönliche ToDo-App als Desktop-Anwendung, in der mehrere Listen verwaltet werden können. Ein Teil der Tasks soll autonom von Claude abgearbeitet werden (z.B. Recherche, Code-Aufgaben, Notizen-Verarbeitung). Die Autonomie läuft in einem getrennten Hintergrund-Prozess, damit die UI davon entkoppelt bleibt.

+# Plan: Per-task model override via MCP + cheapest-model prompt guidance
+
+Spec: `docs/superpowers/specs/2026-06-09-per-task-model-override-design.md`
+
+TDD, one focused commit per task. Build with `-c Release` per project; run
+`ClaudeDo.Worker.Tests` (and `Data.Tests` if touched).
+
+## Task 1 — ModelRegistry: cost ordering + alias validation
+
+- Add `ByCostAscending = ["haiku","sonnet","opus"]`.
+- Add `string? NormalizeAlias(string? model)`: trim; null/blank → null;
+  case-insensitive match against `Aliases` → canonical lowercase; else throw
+  `ArgumentException($"Unknown model '{model}'. Allowed: {join(Aliases)}.")`.
+- Tests (Data.Tests): "sonnet"/"OPUS"/" haiku " → normalized; ""/null/"  " →
+  null; "gpt4" → throws.
+
+## Task 2 — CreateChildAsync accepts model
+
+- `TaskRepository.CreateChildAsync`: add `string? model = null` (before the
+  trailing `CancellationToken ct = default`); set
+  `child.Model = ModelRegistry.NormalizeAlias(model)`.
+- Update the two existing callers to compile (named pass-through added in
+  Tasks 3–4; keep default null here).
+
+## Task 3 — Planning + improvement MCP tools forward model
+
+- `PlanningMcpService.CreateChildTask`: add `string? model` param after
+  `commitType`; pass to `CreateChildAsync`. Extend `[Description]` to document
+  the model arg (haiku/sonnet/opus; cheapest capable).
+- `TaskRunMcpService.SuggestImprovement`: add `string? model` param after
+  `description`; pass to `CreateChildAsync`. Extend `[Description]`.
+- Tests: each tool persists the model; invalid value throws.
+
+## Task 4 — External AddTask forwards model
+
+- `ExternalMcpService.AddTask`: add `string? model = null` param (before the
+  trailing `CancellationToken`); `entity.Model = ModelRegistry.NormalizeAlias(model)`.
+  Extend `[Description]`.
+- Test: AddTask persists model; invalid value rejected.
+
+## Task 5 — Prompt guidance
+
+- `PromptFiles.PlanningSystemDefault`: add a short paragraph — assign each
+  subtask the cheapest model that does it well, with ordering haiku < sonnet <
+  opus and the heuristic; pass it as `CreateChildTask(model=...)`.
+- `PromptFiles.SystemDefault` Out-of-scope section: when filing via
+  `SuggestImprovement`, pass the cheapest capable `model`.
+- `PromptFiles.ImprovementChildDefault`: one-line minimality reminder.
+- No test (static prompt text); verify build only.
+
+## Task 6 — Verify
+
+- Build App + Worker `-c Release`; run Worker.Tests + Data.Tests.
+- Update `ClaudeDo.Worker/CLAUDE.md` (ConfigMcpTools/creation-tool notes) and
+  `ClaudeDo.Data/CLAUDE.md` (ModelRegistry) if needed.

+# Online Inbox — implementation plan
+
+Date: 2026-06-10
+Spec: `docs/superpowers/specs/2026-06-10-online-inbox-design.md`
+Contract: `docs/online-inbox-api-contract.md`
+
+TDD, one commit per task, Conventional Commits. Build with `-c Release` per CLAUDE.md.
+
+## Phase 1 — Worker sync engine (buildable now, no Zitadel package needed)
+
+### Task 1 — Config
+- Add `OnlineInboxConfig` + nested `ZitadelClientConfig` records.
+- Add `online_inbox` (`OnlineInbox`) property to `WorkerConfig`; default `enabled=false`.
+- `Load` leaves it untouched when absent (defaults = disabled).
+- Test: missing section → disabled defaults; populated section round-trips.
+
+### Task 2 — DTOs + Idle-backlog helper
+- `Online/Dtos.cs`: `RemoteList(Id, Name)`, `RemoteTask(Id, ListId, Title, Description, CreatedAt)`,
+  `MirrorTask(Id, ListId, Title, Description)`.
+- `Online/OnlineBacklog.cs`: `static Task<List<MirrorTask>> CurrentAsync(TaskRepository/ctx)` +
+  the filter predicate (Idle, no parent, PlanningPhase None, BlockedBy null).
+- Test the filter against real SQLite seeded with mixed tasks.
+
+### Task 3 — Auth abstraction + token store
+- `Online/Interfaces/IOnlineAuthProvider.cs`.
+- `Online/OnlineTokenStore.cs`: DPAPI CurrentUser persistence at `~/.todo-app/online-inbox.token`;
+  `Save(refreshToken)`, `Read()`, `Clear()`. (Windows-only encryption; thin + guarded.)
+- A trivial `StaticTokenAuthProvider` (returns a configured token or null) for tests + as the
+  temporary default until Zitadel is wired.
+- Test: token store round-trip (Windows); static provider returns/omits token.
+
+### Task 4 — API client
+- `Online/IOnlineInboxApi.cs` + `Online/OnlineInboxApiClient.cs` (typed `HttpClient`).
+- Attaches `Authorization: Bearer` from `IOnlineAuthProvider`; refuses non-HTTPS non-loopback
+  base URLs; throws a typed `OnlineInboxException` on non-2xx.
+- Test with a stubbed `HttpMessageHandler`: each method hits the right path/verb/body; 401
+  surfaces; bearer attached.
+
+### Task 5 — Sync service
+- `Online/OnlineSyncService.cs` (`BackgroundService`) implementing the §5 reconcile loop.
+- DI: register only when `enabled`; resolve repos per-cycle via a scope.
+- Per-cycle try/catch + structured logging; skip when no token; unknown-list skip.
+- Test against a **fake `IOnlineInboxApi`** + real SQLite: pull→import→flag creates local Idle
+  tasks; mirror payload == Idle backlog; lists pushed; unknown list skipped & not flagged;
+  disabled/no-token = no api calls.
+
+### Task 6 — Wire-up + docs
+- Register the stack in `Program.cs` behind the enabled flag.
+- Update `src/ClaudeDo.Worker/CLAUDE.md` (new `Online/` area) and `src/ClaudeDo.Worker/Config`
+  notes. Add `online_inbox` to the config section.
+
+## Phase 2 — UI + real auth (AFTER the VPS reports client config)
+
+### Task 7 — Hub + config plumbing
+- Hub: `GetOnlineInboxConfig` / `SetOnlineInboxConfig` / `SetOnlineInboxAuth(refreshToken)` /
+  `ClearOnlineInboxAuth`. Update `IWorkerClient` + `WorkerClient` + test fakes (both test
+  projects — see the IWorkerClient-fakes memory).
+
+### Task 8 — Settings UI
+- "Online Inbox" section in `SettingsModalViewModel`: enable toggle, base URL, Sign in/out,
+  status. Localized keys in en.json + de.json (parity).
+- Visual verification = manual (flag it).
+
+### Task 9 — ZitadelAuthProvider
+- Add the Zitadel package reference; implement `ZitadelAuthProvider` (refresh-token → access
+  token, cached to expiry) using the reported authority/client-id/flow.
+- Swap it in for `StaticTokenAuthProvider` in DI when enabled.
+- Manual smoke against the live VPS API (tracked, not an automated test).
+
+## Notes
+- No real network / no real Zitadel / no real Claude in any automated test.
+- Stage files by explicit path in subagents; sonnet model; build+test+commit by the orchestrator.

+  - `ActiveConflicts`  = ordered descriptors (block + segment index) for the view.
+- `PositionText` → `"{conflicts} conflicts · {resolved} resolved"` for the active file;
+  keep `CanContinue` = every file resolved AND no binary.
+- Switching files raises a change event the view listens to (reuse/extend
+  `CurrentChanged` → e.g. `ActiveFileChanged`).
+- Tests (Ui.Tests): reconstruction text for ours/theirs/result (result seeds unresolved
+  with Ours); resolving a block updates `ActiveResultText` + readout; switching files
+  preserves each block's `Resolution`; `CanContinue` blocks until all files resolved;
+  binary file still blocks. Keep all existing tests green.
+
+## Task 2 — View: 3-pane AXAML shell + document assembly + synced scroll
+
+`Views/Conflicts/ConflictResolverView.axaml(.cs)`. Visual — verified by running.
+
+- Replace AXAML: ModalShell host kept; header row (◀/▶ focus arrows bound to
+  Previous/Next, file switcher `ItemsControl`/`ComboBox` over `Files` bound to
+  `SelectFileCommand`, right-aligned `PositionText`); `Grid ColumnDefinitions="*,*,*"`
+  of three bordered panes with headers **Ours · current (merge target)** /
+  **Result** / **Theirs · incoming (task)** (drop Base); footer Continue
+  (`IsEnabled=CanContinue`) / Abort; binary banner (kept); `Escape`→Abort (kept).
+- Code-behind: build three `TextDocument`s from `ActiveFile` segments, recording each
+  conflict's start line + line count per document; install TextMate per pane by file
+  extension; rebuild on `ActiveFileChanged`; Ours/Theirs `IsReadOnly=true`.
+- Proportional synced vertical scroll across the three panes (re-entrancy guard).
+- Push Result edits back to the active block `Resolution` (refined in Task 4).
+
+## Task 3 — Result pane: read-only stable, editable conflicts
+
+`ConflictResolverView.axaml.cs` + a small `IReadOnlySectionProvider` helper.
+
+- Track each conflict's result span in a `TextSegmentCollection<…>` over the Result
+  document (anchors auto-adjust on edit).
+- `IReadOnlySectionProvider`: `CanInsert` only strictly inside a conflict span;
+  `GetDeletableSegments` intersects with conflict spans only. Stable text becomes
+  immutable; conflict regions stay editable.
+- Editing inside a conflict span writes the span text back to the block `Resolution`
+  and flips it resolved (updates readout + `CanContinue`).
+
+## Task 4 — Color blocks (IBackgroundRenderer) + accept overlay
+
+`ConflictResolverView.axaml.cs` + renderer/overlay helpers.
+
+- `IBackgroundRenderer` per pane: unresolved conflict = red (Blood tint), resolved =
+  green/muted, Ours side = Moss tint, Theirs side = Accent tint — driven by recorded
+  spans + block `IsResolved`.
+- Between-pane overlay Canvas (Ours|Result and Result|Theirs): `›` accept-ours / `‹`
+  accept-theirs + `✕` dismiss per conflict, positioned at the block's `TextView` visual
+  top, recomputed on scroll/resize. Click → `block.AcceptOurs/AcceptTheirs` and replace
+  the tracked Result span; resolved blocks recolor.
+
+## Task 5 — Polish: readout, focus arrows scroll-to-conflict, resolved styling
+
+- ◀/▶ arrows move `Current` and scroll all three panes to that conflict.
+- `M conflicts · K resolved` live readout; Continue tooltip/hint when blocked.
+- Resolved conflict recolors and drops its accept overlay; unresolved stays red.
+  (Fold into Task 4 if small.)
+
+## Task 6 — Localization + tokens
+
+- Add `conflictResolver.*` keys (pane headers, readout, accept tooltips, hints) to
+  `locales/en.json` AND `locales/de.json` (keep key parity).
+- Add Tokens.axaml color tokens only if a needed conflict/resolved shade is missing.
+- Run Localization.Tests (parity) + a quick scan for hard-coded strings in the view.
+
+## Task 7 — Verify
+
+- Build `ClaudeDo.App` + `ClaudeDo.Ui` `-c Release`; run `Ui.Tests` + `Localization.Tests`.
+- Update `src/ClaudeDo.Ui/CLAUDE.md` (Planning/Conflicts paragraph → new 3-pane editor).
+- **Visual verification gap (flag to Mika):** run the app, trigger a real conflict
+  (single-task approve + planning unit-merge) and confirm panes/colors/accept/scroll/

+# Per-task model override via MCP + cheapest-model prompt guidance
+
+Date: 2026-06-09
+
+## Goal
+
+Let Claude pick the model for each task it generates (planning subtasks,
+improvement follow-ups, external task creation) directly at creation time via
+MCP, and instruct Claude — in the relevant prompts — to choose the *cheapest*
+model that can do the job well.
+
+## Background
+
+- `TaskEntity.Model` (nullable) already exists and is resolved
+  task → list-config → global default in `TaskRunner.ResolveConfigAsync`, then
+  passed to the CLI as `--model` by `ClaudeArgsBuilder`.
+- Today the model can only be set *after* creation via `set_task_config`
+  (`ConfigMcpTools.SetTaskConfig`). The creation tools (`CreateChildTask`,
+  `SuggestImprovement`, `AddTask`) accept no model, so assigning one is a
+  two-call dance.
+- `ModelRegistry.Aliases = ["sonnet","opus","haiku"]`; no cost ordering or
+  validation helper exists.
+
+No schema change is required — only plumbing a `model` argument through the
+creation paths plus prompt edits.
+
+## Decisions
+
+- **Validation:** strict alias-only. `model` must be one of haiku/sonnet/opus
+  (case-insensitive); blank/null means "inherit" (no override); anything else
+  throws an MCP error so Claude self-corrects immediately rather than the task
+  failing later at CLI runtime.
+- **`AddSubtask` is out of scope:** it creates a `SubtaskEntity` (a checklist
+  step), which is never independently executed — a model there is a no-op.
+- **Improvement-child prompt:** the child's model is fixed at filing time and
+  it cannot re-pick, so only a one-line "this is an intentionally small/cheap
+  unit — stay minimal" reminder is added. The real model-choice instruction
+  lives in the main system prompt's SuggestImprovement guidance.
+
+## Cost ordering & heuristic (single source: `ModelRegistry.ByCostAscending`)
+
+`haiku < sonnet < opus`
+
+- **haiku** — trivial/mechanical: doc tweaks, simple renames, small localized edits.
+- **sonnet** — normal coding work (default).
+- **opus** — complex architecture, cross-cutting changes, hard debugging.
+
+## Changes
+
+1. **`ClaudeDo.Data/Models/ModelRegistry.cs`**
+   - `ByCostAscending = ["haiku","sonnet","opus"]`.
+   - `string? NormalizeAlias(string? model)` — trim; null/blank → null;
+     case-insensitive match → canonical lowercase alias; else throw
+     `ArgumentException` with the allowed list.
+
+2. **`TaskRepository.CreateChildAsync`** — add optional `string? model = null`;
+   set `child.Model = ModelRegistry.NormalizeAlias(model)`. Single choke-point
+   for both child-creation MCP tools.
+
+3. **MCP creation tools** (add `model` param, document in `[Description]`):
+   - `PlanningMcpService.CreateChildTask` → forward to `CreateChildAsync`.
+   - `TaskRunMcpService.SuggestImprovement` → forward to `CreateChildAsync`.
+   - `ExternalMcpService.AddTask` → `NormalizeAlias` then set `entity.Model`.
+
+4. **Prompts (`PromptFiles.cs`)**
+   - `PlanningSystemDefault` — instruct the planner to pass each
+     `CreateChildTask` the cheapest capable model (with the ordering/heuristic).
+   - `SystemDefault` (Out-of-scope improvements) — when filing via
+     `SuggestImprovement`, pass the cheapest capable `model`.
+   - `ImprovementChildDefault` — one-line minimality reminder.
+
+5. **Tests** (no real CLI):
+   - `NormalizeAlias`: valid aliases (any case), blank/null → null, unknown → throws.
+   - `CreateChildTask` / `SuggestImprovement` / `AddTask` persist the model;
+     invalid model is rejected.
+
+## Out of scope
+
+- No DB migration. No locale changes (prompts and MCP descriptions are not
+  localized). No UI changes (existing per-task model display already covers it).

+# Online Inbox — desktop-side design
+
+Date: 2026-06-10
+Status: approved, implementing
+Related: `docs/online-inbox-api-contract.md` (the API both ends share)
+
+## Goal
+
+Let the owner add task ideas and view their Idle backlog from a phone/browser. The desktop
+ClaudeDo opts in to an online service, syncs its list catalog + Idle backlog up, and pulls
+web-created tasks down as local `Idle` tasks. Execution stays 100% local.
+
+This spec covers only the **desktop side** (this repo). The API + web client are built
+VPS-side against the shared contract.
+
+## Non-goals
+
+- No remote execution; the Worker still runs everything locally.
+- No syncing of any task state other than the `Idle` mirror.
+- No multi-user. Single Zitadel user = the owner.
+- Web client is create + read only.
+
+## Opt-in & where things live
+
+- **Off by default.** When disabled: zero network, zero auth — byte-for-byte today's
+  behaviour. Auth only matters once enabled.
+- Sync runs in the **Worker** (it owns the DB and already hosts `BackgroundService`s). The
+  opt-in config and the stored refresh token live in `worker.config.json`-adjacent state.
+- Interactive Zitadel login happens in the **UI** (browser flow), which hands the resulting
+  refresh token to the Worker over SignalR; the Worker persists it (DPAPI) and uses it for
+  headless token refresh during polling.
+
+## Config (`WorkerConfig`, new `online_inbox` section)
+
+```jsonc
+"online_inbox": {
+  "enabled": false,
+  "api_base_url": "",            // e.g. https://inbox.claudedo.kuns.dev
+  "poll_interval_seconds": 60,
+  "zitadel": {
+    "authority": "",            // issuer URL  (from VPS report)
+    "client_id": "",
+    "scopes": "openid offline_access"   // offline_access → refresh token
+  }
+}
+```
+
+The refresh token is NOT stored in this file. It lives encrypted via
+`System.Security.Cryptography.ProtectedData` (DPAPI, CurrentUser) at
+`~/.todo-app/online-inbox.token` and is read/written only by the Worker.
+
+## Components (Worker, new `Online/` folder)
+
+```
+Worker/Online/
+  OnlineInboxConfig.cs        — the config record (bound from WorkerConfig.OnlineInbox)
+  Dtos.cs                     — RemoteList, RemoteTask, MirrorTask DTOs (match the contract)
+  IOnlineInboxApi.cs          — typed client surface (one method per endpoint)
+  OnlineInboxApiClient.cs     — HttpClient impl; attaches bearer via IOnlineAuthProvider
+  Interfaces/IOnlineAuthProvider.cs — Task<string?> GetAccessTokenAsync(ct)
+  ZitadelAuthProvider.cs      — concrete (PENDING: needs the Zitadel package + client config)
+  OnlineTokenStore.cs         — DPAPI-backed refresh-token persistence
+  OnlineSyncService.cs        — BackgroundService: the reconcile loop (§contract 5)
+  OnlineBacklog.cs            — static helper: the Idle-backlog query/filter (§contract 2)
+```
+
+### `IOnlineInboxApi`
+```
+Task PutListsAsync(IReadOnlyList<RemoteList> lists, ct)
+Task<IReadOnlyList<RemoteTask>> GetUnimportedTasksAsync(ct)   // GET /tasks?imported=false
+Task MarkImportedAsync(string id, ct)                          // POST /tasks/{id}/imported
+Task PutMirrorAsync(IReadOnlyList<MirrorTask> tasks, ct)       // PUT /tasks/mirror
+```
+(The desktop never calls `POST /tasks`, `GET /lists`, or `GET /lists/{id}/tasks` — those are
+web-only.)
+
+### `IOnlineAuthProvider`
+Single method `Task<string?> GetAccessTokenAsync(CancellationToken)` returning a bearer token
+(refreshing transparently), or `null` if not logged in / refresh failed. Abstracting it lets
+us:
+- ship and test the sync engine now with a fake provider,
+- wire the real `ZitadelAuthProvider` once the VPS reports authority/client-id and we add the
+  Zitadel package reference.
+
+`ZitadelAuthProvider` reads the refresh token from `OnlineTokenStore`, exchanges it for an
+access token, caches the access token until near expiry. **Marked with a
+`// TODO(online-inbox)` until the flow is wired.**
+
+> **Auth correction (2026-06-10):** the `KunsZitadel` nuget package is a *server-side*
+> resource-server helper (`AddKunsZitadel` → `JwtBearer` token *validation*). It belongs on
+> the VPS API, NOT the desktop. The desktop must *acquire* tokens, so `ZitadelAuthProvider`
+> uses a client OIDC flow — `IdentityModel.OidcClient` (auth-code + PKCE, loopback redirect)
+> or the device-authorization grant — against Zitadel's OIDC endpoints, then persists the
+> refresh token via `OnlineTokenStore`.
+
+### `OnlineSyncService` (the loop)
+- Hosted only when `online_inbox.enabled == true` (guarded at registration).
+- Every `poll_interval_seconds`: create a DI scope, resolve `TaskRepository` + `ListRepository`
+  (same pattern as the External MCP app), run the §5 reconcile loop.
+- Skips a cycle (logs at debug) if `GetAccessTokenAsync` returns null (not logged in).
+- All failures are caught per-cycle and logged; never crashes the Worker. Network errors back
+  off to the next interval.
+- Import safety: a pulled task whose `listId` has no local list is skipped + logged (not
+  imported), and NOT marked imported, so it retries once the list exists. Imported tasks land
+  as `Status=Idle, CreatedBy="online"` — they never auto-run; the user queues them locally.
+
+## UI (later increment, after VPS report)
+
+- Settings modal → new "Online Inbox" section: enable toggle, API base URL, **Sign in /
+  Sign out** (Zitadel browser/device flow via the OIDC client lib), connection status.
+- Login produces a refresh token; UI sends it to the Worker via a new hub method
+  `SetOnlineInboxAuth(refreshToken)` → Worker writes it through `OnlineTokenStore`.
+- Config read/write via hub methods `GetOnlineInboxConfig` / `SetOnlineInboxConfig`
+  (mirrors the existing `GetAppSettings`/`UpdateAppSettings` pattern).
+- Visual verification is a manual step (flagged — never claimed working without a run).
+
+## Security
+
+- Disabled → no network, no token read.
+- Bearer attached only over HTTPS `api_base_url`; refuse `http://` non-loopback base URLs.
+- Refresh token encrypted at rest (DPAPI CurrentUser). Never logged.
+- Imported tasks are `Idle` only — no auto-execution path from the web.
+
+## Testing
+
+- `OnlineSyncService` reconcile logic tested against a **fake `IOnlineInboxApi`** + real
+  SQLite (Worker.Tests style): pull→import→flag, mirror set = Idle backlog, list catalog push,
+  unknown-list skip, disabled = no calls, not-logged-in = skipped cycle.
+- `OnlineBacklog` filter tested directly (excludes children/planning/blocked/non-Idle).
+- **No real network and no real Zitadel** in tests — fake the api + auth provider. (Consistent
+  with the no-real-Claude-in-tests rule.)
+- DPAPI token store: round-trip test is Windows-only; guard or keep as a thin wrapper.
+
+## Open items (need the VPS report)
+
+- Exact Zitadel authority/issuer, client id, scopes, and **which grant the Zitadel app is
+  registered for** (auth-code+PKCE with which loopback redirect URI, or device-code). This
+  drives the desktop OIDC client implementation.
+- Final API base URL.
+- Desktop client OIDC library decision: `IdentityModel.OidcClient` (recommended) vs
+  hand-rolled device-code. (`KunsZitadel` is server-side only — see the auth correction
+  above; it's for the VPS API.)

+# Rider-style 3-pane merge editor (conflict resolver redesign)
+
+Date: 2026-06-19
+
+## Goal
+
+Replace ClaudeDo's current conflict resolver (3 read-only columns Base|Ours|Theirs,
+one conflict at a time, accept buttons + editable result below) with a JetBrains
+Rider-style **3-pane merge editor**:
+
+- LEFT = **Ours** (read-only) · current branch / merge target
+- MIDDLE = **Result** (editable) · the merged file being assembled
+- RIGHT = **Theirs** (read-only) · incoming task branch
+
+Whole file per pane (not one conflict at a time), color-coded conflict blocks,
+inline per-hunk accept controls (`›` accept a side into the result, `✕` dismiss),
+a `M conflicts · K resolved` readout, synced scrolling, Continue gated until every
+conflict is resolved, Abort, and a binary-file guard. Visual reference: the
+attached "Merge Revisions" screenshot.
+
+## Background
+
+- Avalonia 12 desktop app; the conflict editor already uses **AvaloniaEdit 12.0.0**
+  + `AvaloniaEdit.TextMate` (theme `StyleInclude` in `src/ClaudeDo.App/App.axaml`).
+- **Backend is kept unchanged.** `WorkerHub.GetMergeConflictDocuments(taskId)` returns
+  each conflicted file as ordered `MergeSegment`s: *stable* text (git's already
+  auto-merged content) interleaved with *conflict* blocks carrying `Ours/Base/Theirs`.
+  `StartConflictMerge` / `WriteConflictResolution` / `Continue[Planning]ConflictMerge` /
+  `Abort[Planning]ConflictMerge` and their `IWorkerClient` mirrors stay as-is.
+  `ConflictMarkerParser` (Data) already produces the segments. **ours = merge target
+  (current branch); theirs = incoming task branch.** Merges are LOCAL-only (no push).
+- **Seam kept unchanged** so single-task AND planning conflict paths keep working:
+  `IslandsShellViewModel.ConflictResolverFactory` + `ShowConflictResolver`
+  (wired in `MainWindow.axaml.cs`), VM ctor `(IWorkerClient, taskId)`,
+  `OpenAsync(targetBranch)`, `OpenForPlanningAsync(parentId, subtaskId)`, `CloseRequested`.
+  The planning-path WIP currently uncommitted in the tree (`OpenForPlanningAsync`,
+  `_conflictTaskId`, `LoadDocumentsAsync`) is part of this seam and is preserved.
+
+### Key insight: the segments already line the panes up
+
+Because every conflicted file is split into *stable* (identical on both sides, git
+auto-merged) and *conflict* (divergent) segments, reconstructing three documents —
+
+- **Ours**   = Σ over segments of (stable.Text | conflict.Ours)
+- **Theirs**  = Σ over segments of (stable.Text | conflict.Theirs)
+- **Result**  = Σ over segments of (stable.Text | conflict.Resolution ?? conflict.Ours)
+
+— yields three documents that are byte-identical in their stable regions and differ
+only inside conflict blocks. So the panes align line-for-line for free, and a real
+client-side 3-way diff is **not** needed for the core feature.
+
+## Decisions
+
+- **Data source = segment-based (no backend change, no DiffPlex).** The worker already
+  applied git's auto-merge; only conflicts remain actionable. The screenshot's
+  "N changes" (non-conflicting hunks shown as separately flippable) are already merged
+  and have nothing to accept, so the readout is **`M conflicts · K resolved`**. True
+  "N changes" parity (raw `:1/:2/:3` blobs + DiffPlex 3-way) is an explicit later
+  add-on that does not touch the seam — see *Out of scope / fast-follow*.
+- **One file at a time + file switcher.** Like Rider's title bar ("Merge Revisions for
+  …file"). When more than one file conflicts, a compact switcher selects the active
+  file; Continue still requires *all* files resolved. (Replaces today's cross-file
+  flattened one-at-a-time navigation as the primary model.)
+- **Result-pane editing model.** The middle document is the merged file. Stable text is
+  read-only via `IReadOnlySectionProvider`; only conflict regions are editable. Each
+  conflict's result span is tracked in a `TextSegmentCollection` (anchors auto-adjust on
+  edit). Accepting `›`(ours)/`‹`(theirs) replaces that span; editing inside it or
+  accepting flips the block to **resolved**. Unresolved regions are seeded with the Ours
+  text and painted red until acted on.
+- **Accept controls = overlay between panes** (not an AvaloniaEdit margin). A thin Canvas
+  overlay between Ours|Result and Result|Theirs hosts `›`/`✕` (and `‹`) per conflict,
+  positioned at each block's visual Y (recomputed on scroll/resize). This matches the
+  screenshot's between-pane gutters and avoids the lack of a built-in right-side margin.
+- **Synced scroll = proportional (Green).** Mirror each pane's vertical scroll offset to
+  the other two with a re-entrancy guard. Aligned/virtual-space scroll + bezier connector
+  curves are a deferred stretch.
+- **Seam + existing VM tests preserved.** Keep `MergeConflictBlock` with its
+  `AcceptOurs/Theirs/Both/Base` commands and `MergeFile.Compose`; keep
+  `Current`/`CurrentIndex`/`Next`/`Previous` repurposed as the focused-conflict the top
+  arrows jump to. New state (active file, readout) is additive.
+
+## Architecture
+
+### ViewModel (`ConflictResolverViewModel`, `ConflictModels.cs`)
+
+Unchanged seam: ctor, `OpenAsync`, `OpenForPlanningAsync`, `CloseRequested`,
+`Continue`/`Abort` (incl. planning routing), `CanContinue` gating, binary guard.
+
+Additive:
+- `ActiveFile` (`MergeFile`) + the switcher list (`Files`) + `SelectFileCommand`.
+- Per-active-file reconstruction exposed for the view and for tests:
+  `ActiveOursText`, `ActiveTheirsText`, `ActiveResultText` (result seeds unresolved =
+  Ours), plus an ordered list of conflict descriptors (the block + its segment index)
+  so the view can compute offsets/spans as it assembles each document.
+- Readout `PositionText` → `"{M} conflicts · {K} resolved"` (active file and/or total);
+  `CanContinue` stays "all files resolved AND no binary".
+- On switching files, block `Resolution` persists (state lives on `MergeConflictBlock`),
+  so progress survives navigation; the view rebuilds documents from the active file.
+
+### View (`Views/Conflicts/ConflictResolverView.axaml` + `.cs`)
+
+- AXAML: ModalShell host (kept), header (prev/next arrows, file switcher, readout),
+  `Grid` of three bordered panes with headers, two between-pane overlay Canvases,
+  footer (Continue/Abort), binary banner, `Escape`→Abort. Drop the Base column.
+- Code-behind builds three `TextDocument`s from `ActiveFile`'s segments, recording each
+  conflict's line span per document; installs TextMate by file extension on all three;
+  rebuilds on file switch; pushes result-pane edits back into the active block's
+  `Resolution` and flips resolved.
+- `IReadOnlySectionProvider` on the Result `TextArea` (stable = read-only, conflicts =
+  editable) backed by a `TextSegmentCollection` of the conflict result-spans.
+- One `IBackgroundRenderer` per pane painting unresolved-conflict (red), resolved
+  (green/muted), and ours/theirs side tints, driven by the recorded spans + block state.
+- Overlay accept controls positioned at each block's `TextView` visual top; click →
+  `block.AcceptOurs/AcceptTheirs` and the code-behind replaces the tracked result span.
+- Proportional synced vertical scroll across the three panes.
+
+### Localization / tokens
+
+- New `conflictResolver.*` keys (pane headers, readout, accept tooltips) in
+  `en.json` + `de.json` (parity enforced by Localization.Tests).
+- Block colors from `Tokens.axaml` (reuse Blood/Moss/Accent tints; add tokens only if a
+  needed shade is missing).
+
+## Out of scope / fast-follow (not in this plan)
+
+- **Raw 3-way diff "N changes" parity (Option B):** a new worker method returning raw
+  `:1/:2/:3` blobs per conflicted file + DiffPlex client-side 3-way diff so
+  non-conflicting changes also appear as accept-able hunks. Seam-preserving; later.
+- **Intra-conflict word/line highlighting** (Rider's "Highlight words") via a line
+  transformer.
+- **Bezier connector curves + aligned / virtual-space synced scroll** (Red stretch).
+- No DB migration, no backend/seam changes, no push.

+## Layout: Islands
 
-- **MainWindow** — 3-column DockPanel layout (lists | tasks | detail) with GridSplitter, status bar at bottom
+`MainWindow` hosts three "islands" (lists | tasks | details). There is no MainWindowViewModel, StatusBarView, or task/list editor modal — the root coordinator is **IslandsShellViewModel**, and task/list editing happens inline in the islands.
-- **TaskListView** — ListBox of tasks with add/edit/delete toolbar
-- **TaskDetailView** — Task info, live log output, worktree section (merge/keep/discard)
-- **TaskEditorView** — Modal dialog for task create/edit
-- **ListEditorView** — Modal dialog for list create/edit
-- **StatusBarView** — Connection status indicator, active task display
-- **ListSettingsModalView** — edits list name, working dir, default commit type, and per-list Model/SystemPrompt/AgentPath/MaxTurns, each showing the inherited (global) value with a source-aware "inherited · Global / override" badge and a reset-to-inherited button; also deletes the list (and its tasks) via a confirmed "Delete list" button. Opened via context menu or gear button on a list row.
-- **RepoImportModalView** — bulk-creates lists from git repos discovered under chosen parent folders. Opened via the folder button beside "New list" in the Lists island, or the "Add repos as lists…" Help-menu item. Repos already wired to a list show as disabled/"(already added)".
-- **DetailsIslandView** — contains an "Agent settings (overrides)" expander with per-task Model/MaxTurns/AgentPath (override semantics, each showing the resolved inherited value as a placeholder plus a source-aware "inherited · List / inherited · Global / override" badge and reset button via the reusable `InheritedBadge` control + `InheritanceResolver`) and a SystemPrompt text box (additive — shows the inherited prompt as a "prepended automatically" note). Disabled while task is running. When notes mode is active (`IsNotesMode`), it hosts **NotesEditorView** instead of the task detail. When prep mode is active (`IsPrepMode`), it hosts the daily-prep panel (Plan day button, empty-state hint, embedded **SessionTerminalView**). The task header, metadata footer (delete/close), and **AgentStripView** are gated on `IsTaskDetailVisible` — they are hidden in both notes and prep mode.
-- **WeeklyReportModalView** — opened from Help menu ("Wochenbericht…"); date-range pickers default to "since last standup weekday → today"; Generate/Regenerate button; renders markdown via MarkdownView; reports are cached per range.
-- **NotesEditorView** — day navigator (prev/next/date-picker/Today), bullet add/edit/delete for daily notes.
-- **SessionTerminalView** — reusable log terminal; exposes StyledProperties `Entries`, `Label`, `IsRunning`, `IsDone`, `IsFailed`. Used for both the task `Log` and the prep `PrepLog`.
-- **SettingsModalView** — Prime Claude tab contains a `DailyPrepMaxTasks` numeric editor.
-- **TasksIslandView** (MyDay header) — icon buttons visible only when `IsMyDayList`: broom icon = `ClearDayCommand`, stroked-sun icon ("Plan My Day") = `ShowPrepLogCommand`.

 ## ViewModels
 
-- **MainWindowViewModel** — root coordinator; manages list collection, selected list, dialog creation via `Func<T>` factories
+- **IslandsShellViewModel** — root coordinator; owns the three island VMs and the `WorkerClient`, wires cross-island events (selection, notes/prep mode, conflict resolution), owns connection state, the update banner, the inline worker-log strip, responsive-layout flags (`ShowLists`/`ShowDetails` by window width), `PrimeStatus` flash, and the modal openers (About, RepoImport, WeeklyReport, WorktreesOverview, WorkerConnection help) plus `RestartWorkerAsync`/`CheckForUpdatesAsync`. Hosts `UpdateCheckService`.
-- **TaskListViewModel** — manages task collection for selected list; handles CRUD, "Run Now"
+- **ListsIslandViewModel** — smart lists (My Day, Important, Planned, virtual queued/running/review), user lists, selection, list CRUD, drag-reorder, badge counts, opens list settings / repo import / worktrees overview, `OpenInExplorer`/`OpenInTerminal`.
-- **TaskDetailViewModel** — displays task details, streams live log, controls worktree operations
+- **TasksIslandViewModel** — open/overdue/completed groups for the selected list with hierarchy-aware regrouping; task CRUD, drag-reorder, toggle done/star, schedule, enqueue/dequeue, cancel; review actions (approve, reject-rerun, reject-park, cancel); planning session lifecycle (open/resume/discard/finalize, `QueuePlanningSubtasksAsync`); `RunInteractivelyAsync`, `RefineTask`; MyDay extras (`IsMyDayList`, `ClearDayCommand`, `ShowPrepLogCommand`) and the pinned Notes pseudo-row (`ShowNotesRow`, `OpenNotesCommand`). Raises `NotesRequested`/`PrepRequested` events consumed by the shell.
-- **TaskItemViewModel** / **ListItemViewModel** — lightweight display VMs
+- **DetailsIslandViewModel** — the detail pane for a bound `TaskRowViewModel`. Owns live-log streaming (`Log` via `StreamLineFormatter`), debounced title/description editing, subtasks, session-outcome/roadblock split (splits `Result` at the roadblock marker into two cards), the three-tab work console (`output`/`git`/`session`), child surfacing (`ChildOutcomes` rows plus `ChildrenNeedingAttention`/`HasChildrenNeedingAttention` — children that failed, were cancelled, await review, or reported roadblocks — drive an attention band on the Session tab, which is only visible when `HasChildOutcomes`), and the modes: `IsNotesMode` (hosts `NotesEditorViewModel`), `IsPrepMode`, computed `IsTaskDetailVisible = !IsNotesMode && !IsPrepMode`. Three concerns are extracted into section VMs exposed as properties: **AgentSettingsSectionViewModel** (per-task Model/MaxTurns/AgentPath overrides with `InheritedBadge` + `InheritanceResolver`, additive SystemPrompt, debounced save), **MergeSectionViewModel** (merge-target selection, mergeability indicator via `MergePreviewPresenter` over `PreviewMergeAsync`, `OpenDiffAsync` — live worktree or commit range after merge —, `ReviewCombinedDiffCommand` → `PlanningDiffViewModel`), **PrepPanelViewModel** (daily-prep panel: `PrepLog`, `PlanDayCommand` → `RunDailyPrepNowAsync`, persisted last run via `GetLastPrepLogAsync`). Helper rows (`ChildOutcomeRowViewModel`, `SubtaskRowViewModel`, `LogLineViewModel`) live in the same file.
-- **TaskEditorViewModel** / **ListEditorViewModel** — dialog VMs with validation
+- **TaskRowViewModel** / **ListNavItemViewModel** — lightweight display VMs (task row: status, planning phase, parent/blocked links, roadblock count, computed `IsDraft`/`IsPlanned`/`IsChild`/`IsPlanningParent`/`CanRefine`; list row: kind Smart/Virtual/User, count, icon/dot keys, drop hints).
-- **StatusBarViewModel** — connection state and active tasks
+- **NotesEditorViewModel** — day navigator + bullet CRUD for daily notes via `INotesApi`.
-- **WeeklyReportModalViewModel** — drives the weekly report modal
+- **Modal VMs** — `SettingsModalViewModel` (four tabs: General, Worktrees, Files prompt-paths, Prime Claude incl. `DailyPrepMaxTasks` + prime-schedule rows), `ListSettingsModalViewModel` (name, working dir, commit type, per-list Model/SystemPrompt/AgentPath/MaxTurns with inherited-badge + reset, delete list), `RepoImportModalViewModel` (bulk-create lists from git repos found under chosen parents; already-wired repos disabled), `WeeklyReportModalViewModel` (range pickers default "since last standup weekday → today", cached per range, markdown via MarkdownView), `MergeModalViewModel` (single-task merge form, called from the diff modal), `WorktreesOverviewModalViewModel` (global/per-list worktree rows, batch merge + state ops), `UnfinishedPlanningModalViewModel` (Resume/FinalizeNow/Discard for a draft planning session), `WorkerConnectionModalViewModel` (offline help), `AboutModalViewModel`.
-- **NotesEditorViewModel** — manages daily note bullet CRUD for the selected day
+- **Diff stack** — `UnifiedDiffParser` (static; parses `git diff` output into `DiffFileViewModel`s, detecting added/deleted/renamed/binary files and per-line numbers; `Flatten` injects file-header rows for a combined single-pane view). `DiffModalViewModel` has two modes: live worktree (branch diff vs base, with a Merge action) and commit-range `base..head` (`FromCommitRange = true` — shows a merged task's diff after its worktree is gone; no merge action). The view renders a file list with binary/empty placeholders via `DiffLinesView`.
-- **DetailsIslandViewModel** gains `IsNotesMode`, `ShowNotes()`, and hosts `NotesEditorViewModel`. Also gains daily-prep mode: `IsPrepMode`, `PrepLog` (`ObservableCollection<LogLineViewModel>`), `ShowPrep()`, `PlanDayCommand` (calls `RunDailyPrepNowAsync`), `ShowPrepEmptyState`, and computed `IsTaskDetailVisible` (= `!IsNotesMode && !IsPrepMode`). Subscribes to `PrepStartedEvent`, `PrepLineEvent`, `PrepFinishedEvent`; streams lines into `PrepLog` via `StreamLineFormatter` (same path as task logs). On open, if log is empty and no run is in progress, loads persisted last run via `GetLastPrepLogAsync`. The WorkConsole Session tab gains a mergeability indicator (`MergePreviewPresenter`) and a single-task Merge button; indicator is populated via `PreviewMergeAsync` and displayed for tasks in WaitingForReview.
+- **Planning/Conflicts** — `PlanningDiffViewModel` (per-subtask diffs via `GetPlanningAggregateAsync`, toggle to combined integration-branch diff, conflict warnings), `ConflictResolverViewModel` (in-app **Rider-style 3-pane merge editor** for both single-task and planning unit-merge conflicts: single-task starts the conflict merge, parses each conflicted file into stable/conflict `MergeFileSegment`s via the worker's `GetMergeConflictDocuments`; exposes the active file's three reconstructed documents — `ActiveOursText` / `ActiveResultText` / `ActiveTheirsText` (from `MergeFile.OursText/ResultText/TheirsText`; Result seeds unresolved conflicts with Ours) — plus `ActiveFile`/`SelectFileCommand` (multi-file switcher), `Current`/`Next`/`Previous` (focused-conflict nav), a per-active-file `PositionText` readout, per-block `AcceptOurs/Theirs/Both/Base` + `MergeFile.Compose`, and `CanContinue` gated on every file resolved + no binary; writes each file via `WriteConflictResolution`, continue/abort; **planning mode** via `OpenForPlanningAsync(parentId, subtaskId)` loads the current subtask's mid-merge conflicts without re-starting the merge and routes continue/abort to `ContinuePlanningMerge`/`AbortPlanningMerge`, so a unit-merge conflict re-opens the editor per subtask via the `PlanningMergeConflict` broadcast). The view (`Views/Conflicts/ConflictResolverView`) shows the whole file in three **AvaloniaEdit** panes — MAIN/ours (read-only) | editable Result | INCOMING/theirs (read-only) — with TextMate highlighting by extension (theme `StyleInclude` in `App.axaml`); a code-behind `IBackgroundRenderer` tints each conflict block (unresolved/resolved) across panes, an `IReadOnlySectionProvider` + `TextAnchor` regions keep only conflict spans editable in Result (edits flow back to the block); each unresolved conflict starts EMPTY (a thin marker bar); the between-pane gutter controls **toggle** each side in/out of the result — `›`/`‹` add MAIN/INCOMING in click order (first pick on top), clicking again removes that side — so a conflict can take main, incoming, both, or neither; a `FilesSummary` readout shows how many files still have conflicts, and the three panes share a proportional synced vertical scroll. A conflict overview ruler right of the Result pane (`ConflictMap`) maps every conflict in the file proportionally (click a tick to jump) — handy for long files. Conflict block tints live in `Tokens.axaml` (`Merge*TintBrush`). The editor is reached from review **Approve** on conflict and from the **Merge** button in the Diff window (a conflicting `MergeTask` hands off to the resolver via `RequestConflictResolution`).
-- **TasksIslandViewModel** gains a pinned "Notes" pseudo-row (`ShowNotesRow`, `OpenNotesCommand`, `NotesRequested` event) that switches the Details island to notes mode. Also gains `IsMyDayList` (true when selected list is `smart:my-day`), `ShowPrepLogCommand` (raises `PrepRequested` event → shell calls `Details.ShowPrep()`), and `ClearDayCommand` (calls `ClearMyDayAsync`).
 
 ## Services
 
-- **WorkerClient** / **IWorkerClient** — SignalR client connecting to `http://127.0.0.1:47821/hub`. Auto-reconnect with exponential backoff. Methods: StartAsync, RunNowAsync, CancelTaskAsync, WakeQueueAsync, ContinueTaskAsync, ResetTaskAsync, GetAgentsAsync, UpdateAppSettingsAsync, UpdateListAsync, UpdateListConfigAsync, GetListConfigAsync, UpdateTaskAgentSettingsAsync, `ApproveReviewAsync(taskId, targetBranch) -> MergeResultDto`, `PreviewMergeAsync(taskId, targetBranch) -> MergePreviewDto`, `MergeTaskAsync`, `GetWeekReportAsync`, `GenerateWeekReportAsync`, `GetDailyNotesAsync`, `AddDailyNoteAsync`, `UpdateDailyNoteAsync`, `DeleteDailyNoteAsync`, `RunDailyPrepNowAsync`, `ClearMyDayAsync`, `GetLastPrepLogAsync`. Events: TaskStarted, TaskFinished, TaskMessage, TaskUpdated, WorktreeUpdated, ListUpdated, `PrepStartedEvent`, `PrepLineEvent`, `PrepFinishedEvent`
+- **WorkerClient** / **IWorkerClient** — SignalR client connecting to `http://127.0.0.1:47821/hub`, auto-reconnect with exponential backoff. The surface tracks `WorkerHub` (see `src/ClaudeDo.Worker/CLAUDE.md` for the canonical method/event list); groups: task execution (RunNow/Cancel/Continue/Reset/SetTaskStatus), review (`ApproveReviewAsync(taskId, targetBranch) -> MergeResultDto`, reject-to-queue/idle, cancel review, `PreviewMergeAsync -> MergePreviewDto`), planning sessions (start/resume/discard/finalize, queue subtasks, pending draft count, interactive terminal, refine), planning aggregate/integration-branch diffs, unit-merge continue/abort, single-task conflict resolving (start/get-conflicts/write-resolution/continue/abort), worktrees (overview, set state, force remove, cleanup, reset all), agents, app settings, lists/config, weekly report, daily notes, daily prep (`RunDailyPrepNowAsync`, `ClearMyDayAsync`, `GetLastPrepLogAsync`), prime schedules. Events mirror `HubBroadcaster` (task/worktree/list/run updates, prep events, planning-merge events, refine events, worker log). Lifecycle (`StartAsync`/`StopAsync`) and a few admin methods live only on the concrete `WorkerClient`.
-- **INotesApi** / **WorkerNotesApi** — thin wrapper over the daily-note WorkerClient methods (mirrors `IPrimeScheduleApi`). UI DTO: `DailyNoteDto(Id, Date, Text, SortOrder)`.
+- **INotesApi** / **WorkerNotesApi** — daily-note CRUD (`ListAsync(day)`, `AddAsync`, `UpdateAsync`, `DeleteAsync`); UI DTO `DailyNoteDto(Id, Date, Text, SortOrder)`.
+- **IPrimeScheduleApi** — prime-schedule CRUD (`ListAsync`, `UpsertAsync`, `DeleteAsync`).
+- **UpdateCheckService** — polls releases, exposes `LastCheckStatus`/`LatestVersion`/`CheckNowAsync` (feeds the shell's update banner).
+- **InheritanceResolver** — resolves the task → list → global override chain to `(value, source)` for the inherited badges.
+- **RepoScanner**, **InstallArtifactLocator**/**InstallerLocator**/**WorkerLocator**, **ForegroundHelper** (Win32 foreground before launching a terminal), **FocusClearing**.
 
 ## Converters
 
-- **StatusColorConverter** — task status string -> color (Queued=Blue, Running=Orange, Done=Green, Failed=Red, Manual=Gray)
+`StatusColorConverter` (+ `ConnectionColorConverter` in the same file), `WorktreeStateColorConverter`, `WorkerLogLevelToBrushConverter`, `DotBrushConverter`, `EqStatusConverter`, `IconKeyConverter`, `CheckboxBorderConverter`, `StrikeIfTrueConverter`, `BoolToItalicConverter`, `BoolToDraftOpacityConverter`, `NotNullToBoolConverter`, `UpperCaseConverter`, `DateOnlyToDateTimeConverter`.
-- **ConnectionColorConverter** — connection state -> color (Online=Green, Offline=Red)
 
 ## Dialog Pattern
 
-Editor dialogs use `TaskCompletionSource<bool>` — the dialog sets the result on save/cancel, and the caller awaits the TCS.
+Modals use `TaskCompletionSource` results behind the reusable `ModalShell` control — the dialog sets the result on save/cancel, and the caller awaits the TCS.
 
 ## Notes
 
-- Context menus are on both list items and task items
+- Context menus exist on both list rows and task rows; right-click selects before opening the menu
-- Right-click selects the item before showing the context menu
 - "Run Now" CanExecute re-evaluates when worker connection state changes
 - Icon gotcha: `PathIcon` fills geometry. Line-art/stroke icons must be defined as filled geometry or rendered as a stroked `Path` (e.g. `Icon.PlanDay` via the `Path.plan-icon` style); a pure stroke path used with `PathIcon` is invisible.
+- `SessionTerminalView` is the reusable log terminal (StyledProperties `Entries`, `Label`, `IsRunning`, `IsDone`, `IsFailed`) used for both the task `Log` and the prep `PrepLog`.

+Per-list config (`list_config` in DB) provides defaults for `model`, `system_prompt`, `agent_path`; tasks can override each individually. Task-generating MCP tools (`AddTask`, planning `CreateChildTask`, `SuggestImprovement`) accept an optional `model` (alias-validated via `ModelRegistry.NormalizeAlias` — `haiku`/`sonnet`/`opus`, blank = inherit) so Claude assigns the cheapest capable model at creation time; the planning/system/improvement prompts instruct it to do so (`ModelRegistry.ByCostAscending` = the cost order).
