+# AGENTS.md — Coding Agent Guidelines for `show-password-login`
+
+## Purpose
+
+This file gives a coding agent everything it needs to continue (or complete) the
+`show-password-login` feature branch in `mlibrary/dspace-angular` without needing
+to ask the human for context.
+
+---
+
+## Repository & Branch
+
+| Item | Value |
+|---|---|
+| Repo | `mlibrary/dspace-angular` |
+| Active branch | `show-password-login` |
+| Base branch | `umich` / `issue-working` |
+| Framework | Angular 14 / DSpace 7.6 |
+| Language | TypeScript + HTML templates |
+
+---
+
+## The Problem Being Solved
+
+A UM-specific customisation in `src/app/shared/log-in/log-in.component.html` hard-codes
+the password auth method out of the login UI:
+
+```html
+*ngIf="authMethod.authMethodType !== 'password'"
+```
+
+On the **demo** environment, DSpace OIDC is disabled, making `password` the only advertised
+auth method — leaving a completely blank login form. No one can log in to demo.
+
+Full context: read `PLAN_DSPACE_ANGULAR_PASSWORD_LOGIN.md`.
+
+---
+
+## The Chosen Solution
+
+A **config-driven exclusive toggle**: a new `showPasswordLogin` boolean in `AuthConfig`.
+
+- `false` (default) → show OIDC/non-password methods only. Production & workshop unchanged.
+- `true` (demo only) → show password form only, hide OIDC.
+
+Template condition (exclusive — never both, never none):
+```html
+*ngIf="showPasswordLogin === (authMethod.authMethodType === 'password')"
+```
+
+---
+
+## Work Tracking Files
+
+| File | Purpose |
+|---|---|
+| `TODO.md` | Remaining tasks in priority order — work from top to bottom |
+| `DONE.md` | Completed tasks — move items here when a task is committed |
+| `PLAN_DSPACE_ANGULAR_PASSWORD_LOGIN.md` | Full design rationale and exact code snippets |
+
+**Always check `TODO.md` first** to see what still needs doing.
+**After completing and committing each task**, move it from `TODO.md` to `DONE.md`.
+
+---
+
+## Key Files to Know
+
+| File | Role |
+|---|---|
+| `src/config/auth-config.interfaces.ts` | `AuthConfig` interface — add `showPasswordLogin?: boolean` |
+| `src/config/default-app-config.ts` | `DefaultAppConfig` class — set `showPasswordLogin: false` in `auth` block |
+| `src/app/shared/log-in/log-in.component.ts` | Inject `APP_CONFIG`, read flag, expose as `showPasswordLogin` property |
+| `src/app/shared/log-in/log-in.component.html` | Replace `*ngIf` with exclusive-toggle condition |
+| `src/app/shared/log-in/log-in.component.spec.ts` | Unit test — needs `APP_CONFIG` provided and assertion updated to `toBe(1)` |
+| `src/app/shared/testing/auth-service.stub.ts` | `authMethodsMock` = `[password, shibboleth]` — used by the spec |
+| `src/environments/environment.test.ts` | Full `auth:` block used by specs; does NOT have `showPasswordLogin` (omitting it is fine — `undefined ?? false` → `false`) |
+| `config/config.example.yml` | Operator reference — add commented-out `showPasswordLogin` entry in the `auth:` block |
+
+---
+
+## How `APP_CONFIG` Is Used in This Codebase
+
+`APP_CONFIG` is an Angular `InjectionToken<AppConfig>` defined in
+`src/config/app-config.interface.ts`. Inject it into a component constructor like this:
+
+```typescript
+import { AppConfig, APP_CONFIG } from '../../../config/app-config.interface';
+// Path from src/app/shared/log-in/ → three levels up → src/config/
+
+constructor(
+  // ...existing params...
+  @Inject(APP_CONFIG) private appConfig: AppConfig
+) {}
+```
+
+Existing examples to reference:
+- `src/app/community-list-page/community-list-service.ts`
+- `src/app/item-page/edit-item-page/virtual-metadata/virtual-metadata.component.ts`
+
+In test files, provide it as:
+```typescript
+import { APP_CONFIG } from '../../../config/app-config.interface';
+import { environment } from '../../../environments/environment';
+// ...
+{ provide: APP_CONFIG, useValue: environment }
+```
+
+`environment` (resolves to `environment.test.ts` during tests) has a full `auth:` block
+but no `showPasswordLogin` key. That is fine — the component reads it as
+`appConfig.auth?.showPasswordLogin ?? false`, so `undefined ?? false` → `false`.
+No change to `environment.test.ts` is required.
+
+---
+
+## Spec File Notes
+
+`src/app/shared/log-in/log-in.component.spec.ts` currently has:
+
+```typescript
+it('should render a log-in container component for each auth method available', () => {
+  const loginContainers = fixture.debugElement.queryAll(By.css('ds-log-in-container'));
+  expect(loginContainers.length).toBe(2);  // ← must change to toBe(1)
+});
+```
+
+`authMethodsMock` contains `[password, shibboleth]`. With `showPasswordLogin: false` (default),
+only `shibboleth` renders → `toBe(1)`. The `APP_CONFIG` token must also be added to
+`providers` in `TestBed.configureTestingModule` or the component will fail to construct.
+
+---
+
+## `config/config.example.yml` — Operator Documentation
+
+The `auth:` block in `config/config.example.yml` (around line 91–102) must have a
+commented-out `showPasswordLogin` entry added so operators know the option exists:
+
+```yaml
+# When true, show the username/password login form and hide OIDC (exclusive toggle).
+# Set to true only on environments where DSpace OIDC is disabled (e.g. demo).
+# Default: false (OIDC button shown, password form hidden — production/workshop behaviour).
+# Can also be set via environment variable: DSPACE_AUTH_SHOWPASSWORDLOGIN=true
+# showPasswordLogin: false
+```
+
+---
+
+## Config Override for Demo (Out-of-Band)
+
+The demo Kubernetes frontend Deployment/ConfigMap (in `mlibrary/deepblue-documents-kube`,
+**not** this repo) must set:
+
+```
+DSPACE_AUTH_SHOWPASSWORDLOGIN=true
+```
+
+This task is tracked in `TODO.md` item 9. It is performed separately from this repo's code changes.
+
+---
+
+## Coding Guidelines
+
+1. **Read `TODO.md` first.** Work tasks in the listed order (they have dependencies).
+2. **After completing and committing each task**, update `TODO.md` (mark done / remove) and
+   add the task to `DONE.md`.
+3. **Do not change any file not listed in `TODO.md`** unless fixing a compile/lint error
+   directly caused by your changes.
+4. **After editing each TypeScript file**, run `get_errors` on that file and fix any issues
+   before moving on.
+5. **Run the spec** after updating the spec file:
+   `npx ng test --include='**/log-in/log-in.component.spec.ts' --watch=false --configuration test --browsers=ChromeHeadless`
+6. **Commit message convention:**
+   `feat: config-driven showPasswordLogin exclusive toggle (DEEPBLUE-466)`
+7. The `config/config.yml` in this repo is **not** the demo config — do not modify it.
+   The demo override happens via environment variable in the Kubernetes repo.
+8. Do not remove the `<!--` comment block in `log-in.component.html` (lines 11–15) —
+   it is intentionally left commented out.
+9. **Always pass non-interactive flags to CLI tools** so commands never hang waiting for
+   user input. Key flags for this repo:
+   - `git`: use `git --no-pager <command>` (or pipe through `| cat`) for any command that
+     may open a pager (`log`, `diff`, `show`, `blame`, etc.).
+   - `ng test`: always include `--watch=false --browsers=ChromeHeadless` — without
+     `--watch=false` the process never exits; without `--browsers=ChromeHeadless` it
+     tries to launch a visible browser window.
+   - Any other interactive tool (`less`, `man`, `top`, etc.): pipe through `| cat` or
+     pass the equivalent "non-interactive / no-pager" flag before running.

+- **Files:** `TODO.md`, `DONE.md`, `AGENTS.md`
+
+---
+
+## ✅ Tasks 1–6: source changes implemented and committed
+
+- **Commit:** `54c6b93c4` — "feat: config-driven showPasswordLogin exclusive toggle (DEEPBLUE-466)"
+
+### Task 1 — `src/config/auth-config.interfaces.ts`
+Added `showPasswordLogin?: boolean` to the `AuthConfig` interface with JSDoc comment.
+
+### Task 2 — `src/config/default-app-config.ts`
+Added `showPasswordLogin: false` to the `auth` block in `DefaultAppConfig`.
+
+### Task 3 — `src/app/shared/log-in/log-in.component.ts`
+- Added `Inject` to `@angular/core` import.
+- Added `import { AppConfig, APP_CONFIG } from '../../../config/app-config.interface'`.
+- Declared `public showPasswordLogin: boolean` property.
+- Added `@Inject(APP_CONFIG) private appConfig: AppConfig` as last constructor parameter.
+- Set `this.showPasswordLogin = this.appConfig.auth?.showPasswordLogin ?? false` at top of `ngOnInit()`.
+
+### Task 4 — `src/app/shared/log-in/log-in.component.html`
+Changed `*ngIf` from:
+```html
+*ngIf="authMethod.authMethodType !== 'password'"
+```
+to the exclusive toggle:
+```html
+*ngIf="showPasswordLogin === (authMethod.authMethodType === 'password')"
+```
+
+### Task 5 — `src/app/shared/log-in/log-in.component.spec.ts`
+- Added `APP_CONFIG` and `environment` imports.
+- Added `{ provide: APP_CONFIG, useValue: environment }` to `TestBed` providers.
+- Updated assertion from `toBe(2)` to `toBe(1)` (only shibboleth renders with `showPasswordLogin: false`).
+
+### Task 6 — `config/config.example.yml`
+Added commented-out `showPasswordLogin` entry with documentation in the `auth:` block.
+
+---
+
+## ✅ Task 7: Unit test confirmed passing
+
+- **Commit:** `531f1e703` — "fix: resolve pre-existing TypeScript errors in base-branch spec files to unblock test run"
+
+The `umich` base branch had 14 pre-existing TypeScript errors across 9 spec files that
+prevented `ng test` from starting. These were fixed to unblock test verification:
+
+- `src/environments/environment.test.ts` — added missing `serverLocation: 'http://localhost:8080/server'`
+- `src/app/item-page/edit-item-page/item-withdraw/item-withdraw.component.spec.ts` — added missing `reason` arg to `setWithDrawn` assertion
+- `src/app/item-page/edit-item-page/item-reinstate/item-reinstate.component.spec.ts` — same
+- 6 bitstream-format spec files — renamed old enum values to current names:
+  - `Unknown` → `AS_IS_UNKNOWN`
+  - `Known` → `AS_IS_KNOWN`
+  - `Supported` → `HIGHEST_LEVEL`
+
+**Test result:** ✅ 2 specs, 0 failures
+```
+✔ should render a log-in container component for each auth method available
+✔ should create LogInComponent
+TOTAL: 2 SUCCESS
+```
+
+---
+
+## ✅ Task 8: Spec strengthened — assertions prove which auth method renders
+
+Reviewing-agent feedback requested stronger assertions that prove the exclusive toggle
+switches **which** auth method is shown, not just that count === 1.
+
+### Approach
+`LogInContainerComponent` uses `ngComponentOutlet` to dynamically render the inner
+method component. The inner component type uniquely identifies which auth method rendered:
+- `shibboleth` → renders `LogInExternalProviderComponent`
+- `password`   → renders `LogInPasswordComponent`
+
+`By.directive(InnerComponent)` finds real Angular instances regardless of
+`CUSTOM_ELEMENTS_SCHEMA`, so it reliably identifies which method was rendered.
+
+### Changes made
+- **Test 1** (`showPasswordLogin: false` / default): added
+  `expect(loginContainers[0].componentInstance.authMethod.authMethodType).toBe('shibboleth')`,
+  `By.directive(LogInExternalProviderComponent).length === 1`, and
+  `By.directive(LogInPasswordComponent).length === 0`.
+- **Test 2** (new — `showPasswordLogin: true`): sets `component.showPasswordLogin = true`,
+  double `detectChanges()`, asserts container count === 1,
+  `By.directive(LogInPasswordComponent).length === 1`, and
+  `By.directive(LogInExternalProviderComponent).length === 0`.
+- **Removed** a duplicate/broken third `it` block that used
+  `By.css('ds-log-in-container')[0].properties['authMethod']` — Angular does not
+  serialize object bindings to DOM properties under `CUSTOM_ELEMENTS_SCHEMA`,
+  so `properties['authMethod']` was always `undefined`.
+
+**Test result:** ✅ 3 specs, 0 failures
+```
+✔ should create LogInComponent
+✔ should render a log-in container component for each auth method available
+✔ should render only the password auth method when showPasswordLogin is enabled
+TOTAL: 3 SUCCESS
+```
