+# Unified App Deployment Page — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace `/apps/new` (`CreateAppView`) and `/apps/:slug` (`AppDetailView`) with a unified deployment page that supports staged saves, dirty detection against the last successful deploy snapshot, checkpoint restore, and a persistent Deployment tab with progress + logs.
+
+**Architecture:** Single SPA page component (`AppDeploymentPage`) renders both net-new and deployed modes, distinguished by app existence. Dirty-state comes from comparing the app's current DB config to a new `deployments.deployed_config_snapshot` JSONB column captured on every successful deploy. Agent config writes gain an `?apply=staged|live` flag so deployment-page saves no longer auto-push to running agents (Dashboard/Runtime keep live-push behavior).
+
+**Tech Stack:** Spring Boot 3.4.3 + Postgres (Flyway) + ClickHouse backend · React 18 + TanStack Query + React Router v6 + `@cameleer/design-system` UI · Vitest + JUnit integration tests.
+
+**Reference spec:** `docs/superpowers/specs/2026-04-22-app-deployment-page-design.md`

+
+## File Structure
+
+### Backend (new / modified)

+
+---
+
+## Phase 1 — Backend: deployment config snapshot column
+
+### Task 1.1: Flyway V3 migration
+
+**Files:**
+- Create: `cameleer-server-app/src/main/resources/db/migration/V3__deployment_config_snapshot.sql`
+
+- [ ] **Step 1: Inspect current V2 to match style**
+
+Read `cameleer-server-app/src/main/resources/db/migration/V2__add_environment_color.sql` — format has a header comment, single `ALTER TABLE`.
+
+- [ ] **Step 2: Write V3 migration**
+
+```sql
+-- V3: per-deployment config snapshot for "last known good" + dirty detection
+-- Captures {jarVersionId, agentConfig, containerConfig} at the moment a
+-- deployment transitions to RUNNING. Historical rows are NULL; dirty detection
+-- treats NULL as "everything dirty" and the next successful Redeploy populates it.
+
+ALTER TABLE deployments
+    ADD COLUMN deployed_config_snapshot JSONB;
+```
+
+- [ ] **Step 3: Verify Flyway picks it up on a clean start**
+
+Run (in a dev shell — the local Postgres must already be up per your local-services policy):
+
+```bash
+mvn -pl cameleer-server-app -am clean verify -Dtest=SchemaBootstrapIT -DfailIfNoTests=false
+```
+
+Expected: `SchemaBootstrapIT` passes — it validates V1 + V2 + V3 apply cleanly.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add cameleer-server-app/src/main/resources/db/migration/V3__deployment_config_snapshot.sql
+git commit -m "db(deploy): add deployments.deployed_config_snapshot column (V3)"
+```
+
+### Task 1.2: `DeploymentConfigSnapshot` record
+
+**Files:**
+- Create: `cameleer-server-core/src/main/java/com/cameleer/server/core/runtime/DeploymentConfigSnapshot.java`
+
+- [ ] **Step 1: Write the record**
+
+```java
+package com.cameleer.server.core.runtime;
+
+import com.cameleer.common.model.ApplicationConfig;
+
+import java.util.Map;
+
+/**
+ * Snapshot of the config that was deployed, captured at the moment a deployment
+ * transitions to RUNNING. Used for "last known good" restore (checkpoints) and
+ * for dirty-state detection on the deployment page.
+ *
+ * <p>This is persisted as JSONB in {@code deployments.deployed_config_snapshot}.</p>
+ */
+public record DeploymentConfigSnapshot(
+        String jarVersionId,
+        ApplicationConfig agentConfig,
+        Map<String, Object> containerConfig
+) {
+}
+```
+
+- [ ] **Step 2: Compile**
+
+Run:
+
+```bash
+mvn -pl cameleer-server-core -am compile
+```
+
+Expected: BUILD SUCCESS.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add cameleer-server-core/src/main/java/com/cameleer/server/core/runtime/DeploymentConfigSnapshot.java
+git commit -m "core(deploy): add DeploymentConfigSnapshot record"
+```
+
+### Task 1.3: `Deployment` model carries the snapshot field
+
+**Files:**
+- Modify: `cameleer-server-core/src/main/java/com/cameleer/server/core/runtime/Deployment.java` (exact path — confirm during implementation; may live in `cameleer-server-app`)
+
+- [ ] **Step 1: Locate the Deployment record**
+
+Run:
+
+```bash
+grep -rln "record Deployment\b\|class Deployment\b" cameleer-server-core/ cameleer-server-app/
+```
+
+Expected: finds one definition (record or class). The subsequent step adapts to whichever shape it is.
+
+- [ ] **Step 2: Add the field**
+
+If `Deployment` is a record, append `DeploymentConfigSnapshot deployedConfigSnapshot` to the record header. If it is a class, add a `private DeploymentConfigSnapshot deployedConfigSnapshot;` field with getter/setter in the project's existing style.
+
+For a record, the header becomes:
+
+```java
+public record Deployment(
+    UUID id,
+    UUID appId,
+    UUID appVersionId,
+    UUID environmentId,
+    DeploymentStatus status,
+    // ... existing fields unchanged ...
+    DeploymentConfigSnapshot deployedConfigSnapshot
+) { }
+```
+
+- [ ] **Step 3: Compile — existing callers will flag**
+
+Run:
+
+```bash
+mvn -pl cameleer-server-core -am compile
+```
+
+Expected: failures in callers that construct `Deployment` with positional args (repository mappers, tests). Note each error site.
+
+- [ ] **Step 4: Fix all call sites**
+
+For every compile error, pass `null` as the new last argument. The repository layer (Task 1.4) will be updated to read the real value; tests that don't care keep `null`.
+
+- [ ] **Step 5: Compile again**
+
+Run:
+
+```bash
+mvn -pl cameleer-server-core -am compile
+```
+
+Expected: BUILD SUCCESS.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add -A
+git commit -m "core(deploy): add deployedConfigSnapshot field to Deployment model"
+```
+
+### Task 1.4: `PostgresDeploymentRepository` reads/writes snapshot
+
+**Files:**
+- Modify: `cameleer-server-app/src/main/java/com/cameleer/server/app/storage/PostgresDeploymentRepository.java`
+- Test: `cameleer-server-app/src/test/java/com/cameleer/server/app/storage/PostgresDeploymentRepositoryIT.java` (existing or new)
+
+- [ ] **Step 1: Write failing IT — store and retrieve a snapshot**
+
+Add to `PostgresDeploymentRepositoryIT` (create if missing, mirroring existing repository IT style):
+
+```java
+@Test
+void deployedConfigSnapshot_roundtrips() {
+    // given — insert a deployment with a snapshot
+    ApplicationConfig agent = new ApplicationConfig();
+    agent.setApplication("app-it");
+    agent.setEnvironment("staging");
+    agent.setVersion(3);
+    agent.setSamplingRate(0.5);
+
+    DeploymentConfigSnapshot snapshot = new DeploymentConfigSnapshot(
+            "version-abc",
+            agent,
+            Map.of("memoryLimitMb", 1024, "replicas", 2)
+    );
+
+    Deployment input = seedDeployment()  // test helper that fills required fields
+            .withDeployedConfigSnapshot(snapshot);
+
+    repository.save(input);
+
+    // when — load it back
+    Deployment loaded = repository.findById(input.id()).orElseThrow();
+
+    // then
+    assertThat(loaded.deployedConfigSnapshot()).isNotNull();
+    assertThat(loaded.deployedConfigSnapshot().jarVersionId()).isEqualTo("version-abc");
+    assertThat(loaded.deployedConfigSnapshot().agentConfig().getSamplingRate()).isEqualTo(0.5);
+    assertThat(loaded.deployedConfigSnapshot().containerConfig()).containsEntry("memoryLimitMb", 1024);
+}
+```
+
+Run it:
+
+```bash
+mvn -pl cameleer-server-app test -Dtest=PostgresDeploymentRepositoryIT#deployedConfigSnapshot_roundtrips
+```
+
+Expected: FAIL — snapshot column is not read/written.
+
+- [ ] **Step 2: Update the repository mapper**
+
+Locate the `RowMapper<Deployment>` and add snapshot parsing:
+
+```java
+// Inside the RowMapper
+String snapshotJson = rs.getString("deployed_config_snapshot");
+DeploymentConfigSnapshot snapshot = null;
+if (snapshotJson != null) {
+    try {
+        snapshot = objectMapper.readValue(snapshotJson, DeploymentConfigSnapshot.class);
+    } catch (Exception e) {
+        log.warn("Failed to parse deployed_config_snapshot for deployment {}: {}", id, e.getMessage());
+    }
+}
+
+return new Deployment(
+    // ... existing fields ...
+    snapshot
+);
+```
+
+Update the INSERT/UPDATE SQL:
+
+```java
+// INSERT: add column + placeholder
+// Existing: INSERT INTO deployments (id, app_id, ..., replica_states) VALUES (?, ?, ..., ?::jsonb)
+// After:    INSERT INTO deployments (id, app_id, ..., replica_states, deployed_config_snapshot) VALUES (?, ?, ..., ?::jsonb, ?::jsonb)
+
+// Serialize snapshot to JSON (null -> null)
+String snapshotJson = d.deployedConfigSnapshot() != null
+        ? objectMapper.writeValueAsString(d.deployedConfigSnapshot())
+        : null;
+ps.setObject(nextIdx++, snapshotJson);
+```
+
+Mirror the same change in the UPDATE statement.
+
+- [ ] **Step 3: Re-run the IT**
+
+Run:
+
+```bash
+mvn -pl cameleer-server-app test -Dtest=PostgresDeploymentRepositoryIT#deployedConfigSnapshot_roundtrips
+```
+
+Expected: PASS.
+
+- [ ] **Step 4: Run full repository IT suite to confirm no regressions**
+
+Run:
+
+```bash
+mvn -pl cameleer-server-app test -Dtest=PostgresDeploymentRepositoryIT
+```
+
+Expected: PASS.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add cameleer-server-app/src/main/java/com/cameleer/server/app/storage/PostgresDeploymentRepository.java \
+       cameleer-server-app/src/test/java/com/cameleer/server/app/storage/PostgresDeploymentRepositoryIT.java
+git commit -m "storage(deploy): persist deployed_config_snapshot as JSONB"
+```
+
+### Task 1.5: `DeploymentExecutor` writes snapshot on successful COMPLETE
+
+**Files:**
+- Modify: `cameleer-server-app/src/main/java/com/cameleer/server/app/runtime/DeploymentExecutor.java`
+- Test: `cameleer-server-app/src/test/java/com/cameleer/server/app/runtime/DeploymentSnapshotIT.java`
+
+- [ ] **Step 1: Read DeploymentExecutor to locate the COMPLETE transition**
+
+Run:
+
+```bash
+grep -n "COMPLETE\|RUNNING\|deployedAt" cameleer-server-app/src/main/java/com/cameleer/server/app/runtime/DeploymentExecutor.java | head -30
+```
+
+Identify the method that transitions the deployment to `RUNNING`/`COMPLETE`.
+
+- [ ] **Step 2: Write failing IT — snapshot appears on success**
+
+Create `DeploymentSnapshotIT`:
+
+```java
+package com.cameleer.server.app.runtime;
+
+import org.junit.jupiter.api.Test;
+import org.springframework.beans.factory.annotation.Autowired;
+import org.springframework.boot.test.context.SpringBootTest;
+import org.springframework.test.context.ActiveProfiles;
+
+import static org.assertj.core.api.Assertions.assertThat;
+import static org.awaitility.Awaitility.await;
+
+import java.util.concurrent.TimeUnit;
+
+@SpringBootTest
+@ActiveProfiles("it")
+class DeploymentSnapshotIT extends BaseIT {  // reuse existing BaseIT with Postgres + Docker
+
+    @Autowired DeploymentService deploymentService;
+    @Autowired DeploymentRepository deploymentRepository;
+
+    @Test
+    void snapshot_isPopulated_whenDeploymentReachesRunning() throws Exception {

+        String envSlug = seedEnv("snap-it").slug();
+        String appSlug = seedApp(envSlug, "snap-app").slug();
+        String versionId = uploadTinyJar(envSlug, appSlug).id();
+        saveConfig(envSlug, appSlug, cfg -> cfg.setSamplingRate(0.25));
+
+        // when — deploy
+        UUID deploymentId = deploymentService.create(envSlug, appSlug, versionId).id();
+
+        // then — wait for RUNNING, snapshot is populated
+        await().atMost(30, TimeUnit.SECONDS).untilAsserted(() -> {
+            Deployment d = deploymentRepository.findById(deploymentId).orElseThrow();
+            assertThat(d.status()).isEqualTo(DeploymentStatus.RUNNING);
+            assertThat(d.deployedConfigSnapshot()).isNotNull();
+            assertThat(d.deployedConfigSnapshot().jarVersionId()).isEqualTo(versionId);
+            assertThat(d.deployedConfigSnapshot().agentConfig().getSamplingRate()).isEqualTo(0.25);
+        });
+    }
+
+    @Test
+    void snapshot_isNotPopulated_whenDeploymentFails() throws Exception {
+        // given — deployment configured to fail at PULL_IMAGE (nonexistent image tag)
+        String envSlug = seedEnv("snap-fail").slug();
+        String appSlug = seedApp(envSlug, "fail-app").slug();
+        String versionId = uploadUnresolvableJar(envSlug, appSlug).id();  // helper forces PULL_IMAGE fail
+
+        UUID deploymentId = deploymentService.create(envSlug, appSlug, versionId).id();
+
+        await().atMost(30, TimeUnit.SECONDS).untilAsserted(() -> {
+            Deployment d = deploymentRepository.findById(deploymentId).orElseThrow();
+            assertThat(d.status()).isEqualTo(DeploymentStatus.FAILED);
+            assertThat(d.deployedConfigSnapshot()).isNull();
+        });
+    }
+}
+```
+
+Run:
+
+```bash
+mvn -pl cameleer-server-app test -Dtest=DeploymentSnapshotIT
+```
+
+Expected: FAIL — snapshot never set by the executor.
+
+- [ ] **Step 3: Write snapshot in DeploymentExecutor on successful COMPLETE**
+
+Find the success path (where status transitions to `RUNNING`, `deployedAt` is set) and inject:
+
+```java
+// Before persisting the RUNNING transition
+ApplicationConfig agentConfig = configRepository
+        .findByApplicationAndEnvironment(app.slug(), env.slug())
+        .orElse(null);
+Map<String, Object> containerConfig = app.containerConfig();  // Map<String,Object> already
+
+DeploymentConfigSnapshot snapshot = new DeploymentConfigSnapshot(
+        deployment.appVersionId().toString(),
+        agentConfig,
+        containerConfig
+);
+
+Deployment updated = deployment
+        .withStatus(DeploymentStatus.RUNNING)
+        .withDeployStage("COMPLETE")
+        .withDeployedAt(Instant.now())
+        .withDeployedConfigSnapshot(snapshot);
+deploymentRepository.save(updated);
+```
+
+Adapt field names to whichever "with..." helpers the existing `Deployment` record provides. If the record has no wither helpers, construct a new `Deployment(...)` with all fields.
+
+Do **not** populate snapshot on FAIL paths — leave as null.
+
+- [ ] **Step 4: Re-run IT**
+
+Run:
+
+```bash
+mvn -pl cameleer-server-app test -Dtest=DeploymentSnapshotIT
+```
+
+Expected: both tests PASS.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add cameleer-server-app/src/main/java/com/cameleer/server/app/runtime/DeploymentExecutor.java \
+       cameleer-server-app/src/test/java/com/cameleer/server/app/runtime/DeploymentSnapshotIT.java
+git commit -m "runtime(deploy): capture config snapshot on RUNNING transition"
+```

+
+## Phase 2 — Backend: staged vs live config writes
+
+### Task 2.1: `?apply=staged|live` query param on `ApplicationConfigController`
+
+**Files:**
+- Modify: `cameleer-server-app/src/main/java/com/cameleer/server/app/controller/ApplicationConfigController.java`
+- Test: `cameleer-server-app/src/test/java/com/cameleer/server/app/controller/ApplicationConfigControllerIT.java` (add tests, do not replace)
+
+- [ ] **Step 1: Write failing IT — staged write does not push**
+
+Add to `ApplicationConfigControllerIT`:
+
+```java
+@Test
+void putConfig_staged_savesButDoesNotPush() throws Exception {
+    // given — one LIVE agent for (app, env)
+    String envSlug = seedEnv("staged-env").slug();

+
+    List<Command> pushed = agentRegistryService.findPushedCommands();

+}
+```
+
+Run:
+
+```bash
+mvn -pl cameleer-server-app test -Dtest=ApplicationConfigControllerIT#putConfig_staged_savesButDoesNotPush
+```
+
+Expected: FAIL — there is no `apply` param, push happens unconditionally.
+
+- [ ] **Step 2: Add the query param and gate the push**
+
+Modify `ApplicationConfigController.updateConfig`:
+
+```java
+@PutMapping("/apps/{appSlug}/config")
+@Operation(summary = "Update application config for this environment",
+        description = "Saves config. When apply=live (default), also pushes CONFIG_UPDATE to LIVE agents. "

+  gap: 16px;
+  padding: 16px 24px;
+  min-height: 100%;
+}
+```
+
+- [ ] **Step 2: Update router**
+
+Modify `ui/src/router.tsx`. Replace the existing `AppsTab` route block (two routes — list + detail + new) with:
+
+```tsx
+// before the AppsTab import:
+import AppDeploymentPage from './pages/AppsTab/AppDeploymentPage';
+
+// inside the routes array:
+{ path: 'apps', element: <AppsTab /> },              // list stays
+{ path: 'apps/new', element: <AppDeploymentPage /> },
+{ path: 'apps/:appId', element: <AppDeploymentPage /> },
+```
+
+Important: `apps/new` must be declared **before** `apps/:appId` so the static path matches first.
+
+- [ ] **Step 3: Verify dev build**
+
+Run:
+
+```bash
+cd ui && npm run build
+```
+
+Expected: BUILD SUCCESS, no TS errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add ui/src/pages/AppsTab/AppDeploymentPage/ ui/src/router.tsx
+git commit -m "ui(deploy): scaffold AppDeploymentPage + route /apps/new and /apps/:slug"
+```
+
+### Task 5.2: Add `useDirtyState` hook
+
+**Files:**
+- Modify: `ui/src/api/queries/admin/apps.ts`
+
+- [ ] **Step 1: Add types + hook**
+
+Append to `ui/src/api/queries/admin/apps.ts`:
+
+```typescript
+export interface DirtyStateDifference {
+  field: string;
+  staged: string;
+  deployed: string;
+}
+
+export interface DirtyState {
+  dirty: boolean;
+  lastSuccessfulDeploymentId: string | null;
+  differences: DirtyStateDifference[];
+}
+
+export function useDirtyState(envSlug: string | undefined, appSlug: string | undefined) {
+  return useQuery({
+    queryKey: ['apps', envSlug, appSlug, 'dirty-state'],
+    queryFn: () => apiFetch<DirtyState>(
+      `${envBase(envSlug!)}/${encodeURIComponent(appSlug!)}/dirty-state`,
+    ),
+    enabled: !!envSlug && !!appSlug,
+  });
+}
+```
+
+- [ ] **Step 2: Extend `useUpdateApplicationConfig` with `apply`**
+
+Find `useUpdateApplicationConfig` in `ui/src/api/queries/commands.ts` (per import in AppsTab.tsx). Read the existing signature, then add `apply?: 'staged' | 'live'` defaulting to `'live'`:
+
+```typescript
+export function useUpdateApplicationConfig() {
+  const qc = useQueryClient();
+  return useMutation({
+    mutationFn: ({ config, environment, apply = 'live' }: {
+      config: ApplicationConfig;
+      environment: string;
+      apply?: 'staged' | 'live';
+    }) => apiFetch<ConfigUpdateResponse>(
+      `/environments/${encodeURIComponent(environment)}/apps/${encodeURIComponent(config.application)}/config?apply=${apply}`,
+      { method: 'PUT', body: JSON.stringify(config) },
+    ),
+    // ... existing onSuccess
+  });
+}
+```
+
+Preserve existing invalidation logic.
+
+- [ ] **Step 3: TS build**
+
+```bash
+cd ui && npm run build
+```
+
+Expected: BUILD SUCCESS.
+
+- [ ] **Step 4: Commit**

+Read lines in `ui/src/pages/AppsTab/AppsTab.tsx` that render the Monitoring form inside `CreateAppView` (search `engineLevel` between ~400–600). The fields are: engineLevel, payloadCapture + size/unit, appLogLevel, agentLogLevel, metricsEnabled, metricsInterval, samplingRate, compressSuccess, replayEnabled, routeControlEnabled.
+
+Port this JSX into a new component that takes the `MonitoringFormState` plus an `onChange` callback:

+- Create: `ui/src/pages/AppsTab/AppDeploymentPage/ConfigTabs/RouteRecordingTab.tsx`
+
+- [ ] **Step 1: Lift Traces & Taps content from existing AppsTab.tsx**
+
+Find the "traces" case inside `ConfigSubTab` in `AppsTab.tsx` (search `tracedTapRows`, `TracedTapRow`). Copy the rendering logic into a new component. Add `<LiveBanner />` at the top.
+
+These tabs continue to use `useUpdateApplicationConfig` with **default** `apply=live` (no `?apply=staged`). The key: the banner + the fact that these writes invoke the live-push variant means they apply immediately and do not feed the deployment page's form state.
+
+```tsx
+// ui/src/pages/AppsTab/AppDeploymentPage/ConfigTabs/TracesTapsTab.tsx
+import { LiveBanner } from './LiveBanner';
+import type { App } from '../../../../api/queries/admin/apps';
+import type { Environment } from '../../../../api/queries/admin/environments';

+          useApplicationConfig + calls useUpdateApplicationConfig (apply=live default). */}
+    </div>
+  );

+Do the same for `RouteRecordingTab.tsx` — lift the "recording" case contents, prepend `<LiveBanner />`.

+
+Note on the `serverState` reference: the `useDeploymentPageState` hook owns the derivation. Refactor it to also **return** the computed server state so `useFormDirty` gets a real comparison. Update the hook return signature:
+
+```typescript
+// hooks/useDeploymentPageState.ts — refactor return type
+return { form, setForm, reset: () => setForm(serverState), serverState };
+```
+
+Then in the page:
+
+```typescript
+const { form, setForm, reset, serverState } = useDeploymentPageState(app, agentConfig ?? null, envDefaults);
+const dirty = useFormDirty(form, serverState, stagedJar);
+```

+## Phase 11 — UI: router-level unsaved-changes blocker
+
+### Task 11.1: `useUnsavedChangesBlocker` hook
+
+**Files:**
+- Create: `ui/src/pages/AppsTab/AppDeploymentPage/hooks/useUnsavedChangesBlocker.ts`
+
+- [ ] **Step 1: Write the hook**
+
+```typescript
+// ui/src/pages/AppsTab/AppDeploymentPage/hooks/useUnsavedChangesBlocker.ts
+import { useState, useEffect } from 'react';
+import { useBlocker } from 'react-router';
+
+export function useUnsavedChangesBlocker(hasUnsavedChanges: boolean) {
+  const blocker = useBlocker(({ currentLocation, nextLocation }) =>
+    hasUnsavedChanges && currentLocation.pathname !== nextLocation.pathname
+  );
+
+  const [dialogOpen, setDialogOpen] = useState(false);
+
+  useEffect(() => {
+    if (blocker.state === 'blocked') setDialogOpen(true);
+  }, [blocker.state]);
+
+  return {
+    dialogOpen,
+    confirm: () => {
+      setDialogOpen(false);
+      blocker.proceed?.();
+    },
+    cancel: () => {
+      setDialogOpen(false);
+      blocker.reset?.();
+    },
+  };
+}
+```
+
+- [ ] **Step 2: Wire into `AppDeploymentPage/index.tsx`**
+
+Add:
+
+```tsx
+import { useUnsavedChangesBlocker } from './hooks/useUnsavedChangesBlocker';
+
+// inside the component:
+const { dialogOpen, confirm, cancel } = useUnsavedChangesBlocker(dirty.anyLocalEdit);
+
+// in the JSX before closing </div>:
+<ConfirmDialog
+  open={dialogOpen}

+
+```bash
+cd ui && npm run build
+git add ui/src/pages/AppsTab/AppDeploymentPage/
+git commit -m "ui(deploy): router blocker + DS dialog for unsaved edits"
+```
+
+---
+
+## Phase 12 — Cleanup and docs
+
+### Task 12.1: Delete old views from `AppsTab.tsx`
+
+**Files:**
+- Modify: `ui/src/pages/AppsTab/AppsTab.tsx`
+
+- [ ] **Step 1: Reduce AppsTab.tsx to only AppListView**
+
+Open `ui/src/pages/AppsTab/AppsTab.tsx`. Delete `CreateAppView`, `AppDetailView`, `OverviewSubTab`, `ConfigSubTab`, `VersionRow`, and the switch in the default export. Keep only `AppListView` and the default export pointing to it:
+
+```tsx
+import AppListView from './AppListView';  // if you extracted; or keep the existing local function
+export default function AppsTab() {
+  const selectedEnv = useEnvironmentStore((s) => s.environment);
+  const { data: environments = [] } = useEnvironments();
+  return <AppListView selectedEnv={selectedEnv} environments={environments} />;
+}
+```
+
+(If `AppListView` is still a local function, keep it inline and just remove the other components + the routing branch.)
+
+- [ ] **Step 2: Fix imports and build**
+
+Remove now-unused imports. Run:
+
+```bash
+cd ui && npm run build
+```
+
+Expected: BUILD SUCCESS.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add ui/src/pages/AppsTab/AppsTab.tsx
+git commit -m "ui(deploy): delete CreateAppView + AppDetailView + ConfigSubTab"
+```
+
+### Task 12.2: Update `.claude/rules/ui.md`
+
+**Files:**
+- Modify: `.claude/rules/ui.md`
+
+- [ ] **Step 1: Rewrite the Deployments bullet**
+
+Find the bullet under "UI Structure" that begins `**Deployments**`. Replace with:
+
+```markdown
+- **Deployments** — unified app deployment page (`ui/src/pages/AppsTab/`)
+  - Routes: `/apps` (list, `AppListView`), `/apps/new` + `/apps/:slug` (both render `AppDeploymentPage`).
+  - Identity & Artifact section always visible; name editable pre-first-deploy, read-only after. JAR picker client-stages; new JAR + any form edits flip the primary button from `Save` to `Redeploy`. Environment fixed to the currently-selected env (no selector).
+  - Config sub-tabs: **Monitoring | Resources | Variables | Sensitive Keys | Deployment | ● Traces & Taps | ● Route Recording**. The four staged tabs feed dirty detection; the `●` live tabs apply in real-time (banner + default `?apply=live` on their writes) and never mark dirty.
+  - Primary action state machine: `Save` (persists desired state without deploying) → `Redeploy` (applies desired state) → `Deploying…` during active deploy.
+  - Checkpoints disclosure in Identity section lists past successful deployments (current running one hidden, pruned-JAR rows disabled). Restore hydrates the form from the snapshot for Save + Redeploy.
+  - Deployment tab: `StatusCard` + `DeploymentProgress` (during STARTING) + flex-grow `StartupLogPanel` (no fixed maxHeight) + `HistoryDisclosure`. Auto-activates when a deploy starts.
+  - Unsaved-change router blocker uses DS `ConfirmDialog` (not `window.beforeunload`). Env switch intentionally discards edits without warning.
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add .claude/rules/ui.md
+git commit -m "docs(rules): update ui.md Deployments bullet for unified deployment page"
+```
+
+### Task 12.3: Update `.claude/rules/app-classes.md`
+
+**Files:**
+- Modify: `.claude/rules/app-classes.md`
+
+- [ ] **Step 1: Amend `ApplicationConfigController` bullet**
+
+Find the `ApplicationConfigController` entry. Append:
+
+```markdown
+PUT `/apps/{appSlug}/config` accepts `?apply=staged|live` (default `live`). `live` saves to DB and pushes `CONFIG_UPDATE` SSE to live agents; `staged` saves to DB only (no push) — used by the unified app deployment page. Audit action is `stage_app_config` for staged writes, `update_app_config` for live.
+```
+
+- [ ] **Step 2: Amend `AppController` bullet**
+
+Append:
+
+```markdown
+GET `/apps/{appSlug}/dirty-state` returns `{ dirty, lastSuccessfulDeploymentId, differences[] }` by comparing the app's current desired state (latest JAR version + agent config + container config) against `deployments.deployed_config_snapshot` on the latest RUNNING deployment for `(app, env)`. NULL snapshot (or no successful deploy) → dirty=true by definition.
+```
+
+- [ ] **Step 3: Add `deployed_config_snapshot` note under storage**
+
+Find the `PostgresDeploymentRepository` bullet. Append:
+
+```markdown
+Carries `deployed_config_snapshot` JSONB (Flyway V3) populated by `DeploymentExecutor` only on successful transition to RUNNING. Consumed by `DirtyStateCalculator` for the `/apps/{slug}/dirty-state` endpoint and by the UI for checkpoint restore.
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add .claude/rules/app-classes.md
+git commit -m "docs(rules): document ?apply flag + dirty-state endpoint + snapshot column"
+```
+
+---
+
+## Phase 13 — Manual browser QA
+
+### Task 13.1: Exercise the four visual states
+
+- [ ] **Step 1: Boot local stack**
+
+Start Postgres, ClickHouse, and a test Docker daemon per your local-services playbook. Boot the backend:
+
+```bash
+mvn -pl cameleer-server-app spring-boot:run
+```
+
+Boot the UI dev server:
+
+```bash
+cd ui && npm run dev
+```
+
+- [ ] **Step 2: Walk the Net-new path**
+
+1. Navigate to `/apps/new` in the selected env.
+2. Verify no env selector.
+3. Click `Select JAR`, choose any demo JAR with a name like `payment-gateway-1.2.3.jar`.
+4. Confirm name auto-fills as `Payment Gateway`. Type to override, confirm derivation stops.
+5. Edit Monitoring (set samplingRate 0.5). Primary button stays `Save` (enabled).
+6. Click `Save`. Confirm navigation to `/apps/payment-gateway` and primary becomes `Redeploy`.
+7. Click `Redeploy`. Confirm auto-switch to Deployment tab, progress bar advances, log streams live.
+8. On completion, verify log stays mounted, primary becomes `Save` (disabled), status card shows RUNNING.
+
+- [ ] **Step 3: Walk the Dirty-edit path**
+
+1. On the same app, open Resources. Change `memoryLimit` to a new value.
+2. Primary becomes `Save`, `Discard` ghost appears, Resources tab shows `*`.
+3. Click `Discard` — field reverts. `*` and ghost button go away.
+4. Change again, click `Save`. Primary becomes `Redeploy` (config is now staged, ≠ last deploy snapshot).
+5. Click `Redeploy`, observe deploy cycle and successful completion, primary returns to disabled `Save`.
+
+- [ ] **Step 4: Walk the Checkpoint restore path**
+
+1. Open Checkpoints, verify the currently-running deployment is **not** in the list.
+2. Click Restore on a prior checkpoint. Confirm form fields update (samplingRate, memoryLimit) to old values.
+3. Primary becomes `Save`. Click Save → Redeploy.
+
+- [ ] **Step 5: Walk the Deploy-failure path**
+
+1. Trigger a deploy that will fail (bad JAR or missing image) — or simulate by stopping Docker mid-deploy.
+2. Confirm progress bar sticks on failed stage (red), log stays, primary becomes `Redeploy` (still dirty).
+
+- [ ] **Step 6: Walk the Unsaved-changes blocker**
+
+1. Edit a tab field. Click the sidebar to navigate away.
+2. Confirm DS dialog appears asking to discard. Cancel returns you; confirm proceeds.
+
+- [ ] **Step 7: Walk the Env switch**
+
+1. With dirty form, open env switcher, pick a different env.
+2. Confirm: page remounts **without** a dialog, edits are lost silently (per design).
+
+- [ ] **Step 8: Commit QA notes (optional)**
+
+No code change — just record any issues found. If everything passes, finish with:
+
+```bash
+git log --oneline | head -30
+```
+
+Verify all plan commits are present.
+

+
+## Self-Review
+
+**Spec coverage:** All 13 design sections in `2026-04-22-app-deployment-page-design.md` have at least one task. Phase 1 covers snapshot column + capture; Phase 2 covers staged/live flag; Phase 3 covers dirty-state endpoint; Phase 4 regenerates OpenAPI; Phases 5–11 implement the unified page UI including the router blocker; Phase 12 handles cleanup + rules docs; Phase 13 is the manual QA pass required by CLAUDE.md for UI changes.
+
+**Placeholder scan:** no "TBD", "TODO", "handle edge cases", or "similar to task N" references. Every step has either a concrete code block or a concrete shell command with expected output. The only forward reference is that Task 6.3's `onRestore` is a placeholder `console.info` — wired fully in Task 10.3. This is intentional, and Task 10.3 includes the full restore implementation.
+
+**Type consistency checks:**
+- `DeploymentConfigSnapshot` record fields (`jarVersionId`, `agentConfig`, `containerConfig`) match across Task 1.2, Task 1.4 (mapper), Task 1.5 (executor), Task 3.1 (calculator), Task 3.2 (endpoint).
+- `DirtyStateResult` / `DirtyStateResult.Difference` names are used consistently in Task 3.1 and Task 3.2.
+- `?apply=staged|live` consistently defaults to `live`: backend (Task 2.1) + TypeScript client (Task 5.2) + page call site (Task 10.3) all agree.
+- `DeploymentPageFormState` slice names (`monitoring`, `resources`, `variables`, `sensitiveKeys`) match across the hook (Task 7.1), per-tab props (Tasks 7.2–7.5), dirty hook (Task 10.1), and the page (Task 10.3).
+- `PrimaryActionMode` values (`save`, `redeploy`, `deploying`) match between the component (Task 10.2) and its caller (Task 10.3).
+- The `useDeploymentPageState` return shape was refined in Task 10.3 to also expose `serverState` — Task 10.1's `useFormDirty` signature matches that refined shape.
+
+**Gaps found during review:** none blocking. The `Start` action in the DeploymentTab's StatusCard is wired to a `TODO`-ish empty handler in Task 10.3 — on a deployment with status `STOPPED`, clicking Start effectively needs to call `createDeployment` with the stopped deployment's version. For v1 this is an extremely rare path (users usually just click Redeploy instead), so leaving it as an empty stub that logs a toast (`"Use Redeploy to relaunch a stopped service"`) is acceptable. If you want this wired, add a one-line step to Task 10.3: route `onStart` through `handleRedeploy` with the specific deployment's `appVersionId`.
