+
+### Changed
+- Signup and the profile page now ask for a **birth year** rather than a full date of birth — a four-digit year between 1900 and the current year, with anything else discarded rather than stored. Students added before this change keep showing a birth year, derived from the date already on file; that old full date is then dropped the first time the record is saved, so the studio ends up holding only what it now asks for. No bulk purge runs, so a site wanting the remaining old dates gone should clear the `us_date_of_birth` user meta directly.
+- The interface now says **student** where it said "child" and **profile** where it said "family". The `[us_family]` page is headed **Your profile**, its form is **Add a student**, signup asks for a **Student's name**, and the wp-admin students list and student screen both label the relationship **Profile**. Two strings were reworded rather than swapped: the students list reads **Managed by _name_** (a bare "Student of _name_" would read as a teacher's pupil), and a managed account is described as a **managed student account** so it is not confused with the account holder. Internal names — database columns, request parameters, form field names, the `us_family` shortcode and the `us-scheduler/family` block — are unchanged, since they are contracts with existing installs and saved post content.
+
+### Fixed
+- Upcoming lesson rows no longer render on top of each other. The row's text sits in inline elements that a theme can pull out of normal flow, which dropped the date and time onto the lesson title and the status pill onto the Cancel button; those elements are now pinned into flow alongside the rest of the panel's theme-proofing. The rows held behind **Show all** also stayed visible under the `div { display: block }` reset that many themes still carry, since `[hidden]` is only a browser default — they are now hidden for real.

 ## Architecture
 
-### Plugin Bootstrap
-`unsupervised-schedular.php` defines constants (`USC_VERSION`, `USC_PLUGIN_DIR`, `USC_PLUGIN_URL`), registers activation/deactivation hooks, then calls `Plugin::boot()` on `plugins_loaded`. No logic lives in the root file.
-
-### Directory Structure
-```
-src/                  — All plugin PHP (PSR-4 namespace: Unsupervised\Schedular\)
-  Availability/       — Availability slots: value object, repository, controller, REST endpoint
-  Booking/            — Lessons/bookings: value object, repository, controller, REST endpoint, shortcode page
-  Auth/               — Roles, capabilities, login page
-  Plugin.php          — Wires all components together on plugins_loaded

-**Code is organised package-by-domain** (Availability, Booking, Auth). Each domain package contains everything related to that domain: value objects, repositories, controllers, REST endpoints, and shortcode pages. Cross-cutting wiring classes (Plugin, AdminMenu, RestRegistrar, ShortcodeRegistrar, Schema) live directly under `src/`.
+### Code organisation
+**Code is organised package-by-domain.** Each domain package under `src/<Domain>/` contains everything related to that domain: value objects, repositories, controllers, REST endpoints, and shortcode pages. Cross-cutting wiring classes (Plugin, AdminMenu, RestRegistrar, ShortcodeRegistrar, Schema) live directly under `src/`.
 
 ### Data Storage
-Two custom database tables (created via `dbDelta` on activation):
-- `{prefix}us_availability` — instructor availability windows
-- `{prefix}us_lessons` — booked lessons
+Custom database tables are created via `dbDelta` on activation; `Schema.php` holds the SQL.
 
 All database access goes through repository classes within their domain package. No direct `$wpdb` calls outside repositories.
 
-### Key Classes
-
-| Class | Responsibility |
-|---|---|
-| `Plugin` | Wires all components together on `plugins_loaded` |
-| `Installer` | Creates DB tables and roles on activation |
-| `Schema` | CREATE TABLE SQL strings for dbDelta |
-| `AdminMenu` | Registers wp-admin menu pages |
-| `RestRegistrar` | Registers all REST routes under `us-scheduler/v1` |
-| `ShortcodeRegistrar` | Registers `[us_booking]` and `[us_student_login]` shortcodes |
-| `BlockRegistrar` | Registers Gutenberg dynamic-block wrappers for the shortcodes |
-| `BlockPreview` | Static editor-preview markup for the blocks |
-| `Val` | Runtime coercion of untyped WP boundary values (wpdb rows, REST params, superglobals) |
-| `Auth\RoleManager` | Registers `us_instructor` and `us_student` roles with custom caps |
-| `Auth\LoginPage` | Renders front-end student login form |
-| `Availability\AvailabilitySlot` | Immutable value object for a slot row |
-| `Availability\AvailabilityRepository` | CRUD for availability slots |
-| `Availability\AvailabilityController` | Instructor availability management page |
-| `Availability\AvailabilityEndpoint` | REST handlers for availability CRUD |
-| `Booking\Lesson` | Immutable value object for a lesson row |
-| `Booking\BookingRepository` | CRUD for lesson bookings |
-| `Booking\BookingEndpoint` | REST handlers for booking and status updates |
-| `Booking\BookingPage` | Renders student booking UI shell (JS takes over) |
-| `Booking\LessonController` | Admin and instructor lesson list pages |
-
 ### REST API Namespace
 All endpoints live under `/wp-json/us-scheduler/v1/`. Permissions are enforced via `permission_callback` using capability checks (`manage_availability`, `book_lesson`), never role name checks.
 
 ### Testing Approach
-Tests use [Brain\Monkey](https://brain-wp.github.io/BrainMonkey/) to stub WordPress functions without a full WP installation, and Mockery to mock `$wpdb` and other dependencies.
-
-All test classes extend `tests/Unit/TestCase.php`, which handles `Monkey\setUp()` / `Monkey\tearDown()` and stubs all WP translation/escape functions automatically.
-
-**Brain\Monkey API notes:**
-- `Functions\when('fn')->alias(fn() => ...)` — stub with a closure (NOT `returnUsing()`)
-- `Functions\when('fn')->justReturn($val)` — stub returning a fixed value
-- `Functions\expect('fn')->once()->with(...)` — assert call count and arguments
-- Use `Functions\when()` (not `Functions\expect()`) when you need argument-routing (e.g. `get_role` returning different values per argument) to avoid chaining ambiguity
-- Mockery matchers (e.g. `\Mockery::type()`) inside plain PHP arrays do not work with `with()` — use `\Mockery::on(fn($arr) => ...)` or `\Mockery::any()` instead
-- When mocking `$wpdb`, set `$mock->prefix = 'wp_'` explicitly — it is a public property, not a method
+Tests stub WordPress with Brain\Monkey rather than booting a real WP install. The setup and the Brain\Monkey/Mockery API gotchas are in `tests/CLAUDE.md`.
 
 ### Adding a Feature
 0. **If the feature touches `Schema.php`, bump both the `Version:` header and `USC_VERSION` in `unsupervised-schedular.php`.** `Plugin::boot()` only re-runs `Installer`/`dbDelta` when the stored `us_schedular_version` differs, so a schema change without a version bump never reaches existing sites and inserts into new columns fail silently.
@@ -106,10 +29,3 @@ All test classes extend `tests/Unit/TestCase.php`, which handles `Monkey\setUp()
 3. Add template(s) under `templates/` if needed.
 4. Write unit tests under `tests/Unit/<Domain>/` mirroring the `src/<Domain>/` structure.
 5. Run `composer test` — all tests must pass before the feature is complete.

-### CI
-Gitea Actions (`.gitea/workflows/ci.yml`) runs on every push and pull request:
-- **lint** — PHPCS WordPress coding standards
-- **static-analysis** — PHPStan level 10
-- **test** — PHPUnit on PHP 8.1, 8.2, 8.3
-- **no-debug** — rejects commits with `var_dump`, `error_log`, etc. in `src/`

+### The legacy `us_date_of_birth` meta
+
+This feature originally collected a full date of birth in `us_date_of_birth`.
+Nothing writes that key any more. It is handled entirely inside
+`GuardianService`:
+
+- **Read** — `birthYear()` falls back to the year of the old date when
+  `us_birth_year` is absent, so a child added before the change still shows one
+  without a migration step.
+- **Write** — `setBirthYear()` deletes `us_date_of_birth` on *every* save,
+  including a save that clears the year. Without that the fallback would
+  resurrect the old date on the next read and the year could never be cleared.
+
+The upshot is a lazy migration: a child's full date survives until their record
+is next edited, then goes for good. There is no bulk purge — a site that wants
+the remaining old dates gone should delete the `us_date_of_birth` meta directly.

+# Writing tests
+
+Tests use [Brain\Monkey](https://brain-wp.github.io/BrainMonkey/) to stub WordPress functions without a full WP installation, and Mockery to mock `$wpdb` and other dependencies.
+
+All test classes extend `tests/Unit/TestCase.php`, which handles `Monkey\setUp()` / `Monkey\tearDown()` and stubs all WP translation/escape functions automatically.
+
+**Brain\Monkey API notes:**
+
+- `Functions\when('fn')->alias(fn() => ...)` — stub with a closure (NOT `returnUsing()`)
+- `Functions\when('fn')->justReturn($val)` — stub returning a fixed value
+- `Functions\expect('fn')->once()->with(...)` — assert call count and arguments
+- Use `Functions\when()` (not `Functions\expect()`) when you need argument-routing (e.g. `get_role` returning different values per argument) to avoid chaining ambiguity
+- Mockery matchers (e.g. `\Mockery::type()`) inside plain PHP arrays do not work with `with()` — use `\Mockery::on(fn($arr) => ...)` or `\Mockery::any()` instead
+- When mocking `$wpdb`, set `$mock->prefix = 'wp_'` explicitly — it is a public property, not a method
