+## [1.4.0]
+
+### Added
+- An **Account** block (`[us_account]`) showing who is signed in — their name and their email — and a **Sign out** link. Signing out returns to the login page chosen in the block, or to the page the visitor was already on when none is set, so putting it in a site header does not also move people somewhere. To a signed-out visitor it shows a **Sign in** link when a login page is chosen, and nothing at all when one is not: a panel about who is signed in has nothing to tell a stranger, and a notice they cannot act on is just clutter in a header.
+
+### Security
+- Signup now checks the password properly. The form scores it as you type with the same zxcvbn meter wp-admin uses and will not submit a weak one, and the server refuses — regardless of what the browser allowed — anything shorter than 8 characters, one of the well-known leaked passwords, one built from barely any distinct characters, or one containing your own name or email address. Composition rules ("must contain a symbol") are deliberately not imposed: they mostly produce predictable substitutions. Email addresses are validated on the server on every signup path, with a clear message when one is already registered.
+
+### Changed
+- Signup now asks **"Who are you registering?"** as a three-way choice — **just myself**, **on behalf of one or more students**, or **both** — in place of the single parent/guardian tick. The tick could only ever say "I have children to add"; it could not say whether the account holder was a student themselves, so every account was offered its own name in the **Who is this for?** picker whether or not anyone meant to book them a lesson. Choosing *on behalf of* now leaves the account holder out of that picker. Existing accounts are unaffected and stay bookable, since the flag records only the new "not a student" case.
+- The studio's **account-signup questions are now asked of anyone registering as a student**, including someone registering themselves alongside their children. Choosing **both** previously collected the questions per child only, so the account holder's own instrument, level and the rest were never asked for or stored, even though they could book lessons. Their answers are recorded against their own account, and a blank required answer now names them rather than blaming "each student".
+- A student's **name and birth year are now required**, marked in the form the same way a required registration question is and enforced on the server whichever way they were submitted. On signup the requirement applies only once the parent/guardian box is ticked, so registering for yourself is unaffected. A student block you have started filling in is now reported back to you rather than silently dropped when the name is missing — only a completely untouched spare block is still ignored.
+- 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
+- **Booking a lesson no longer dead-ends on the confirmation.** The confirmation used to replace the calendar entirely, leaving a student who wanted a second lesson with nothing to click and no way back short of reloading the page. It is now a dismissible notice sitting above a freshly loaded calendar — the slot just taken already gone from it, the upcoming-lessons panel already updated — so "it worked" and "book another" are the same screen. Enrolling in a group class did the same thing and is fixed the same way.
+- 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
-  Installer.php       — Creates DB tables and roles on activation
-  Schema.php          — CREATE TABLE SQL for dbDelta
-  AdminMenu.php       — Registers wp-admin menu pages
-  RestRegistrar.php   — Registers all REST routes under us-scheduler/v1
-  ShortcodeRegistrar.php — Registers [us_booking] and [us_student_login] shortcodes
-  BlockRegistrar.php  — Registers Gutenberg dynamic-block wrappers for the shortcodes
-  BlockPreview.php    — Static editor-preview markup for the blocks
-templates/            — PHP view files included by controllers/shortcodes
-assets/               — CSS and JS (vanilla JS, no build step)
-tests/Unit/           — PHPUnit unit tests (PSR-4: Unsupervised\Schedular\Tests\)
-  Availability/       — Tests for src/Availability/
-  Booking/            — Tests for src/Booking/
-  Auth/               — Tests for src/Auth/
-docs/features/        — One markdown file per feature describing data model, API, and test locations
-```
-
-**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.

 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/`

+## Email and password validation
+
+Both are checked on the server on every signup path, and the browser is given a
+matching but *stricter* job so a bad password is caught before submitting.
+
+**Email** — `type="email"` and `required` in the markup, `is_email()` on the
+server, then `email_exists()` for "an account already exists for this email". A
+personal invite fixes the address and the server always uses the invite's own
+value, so a tampered field is ignored rather than validated.
+
+**Password** — `Auth\PasswordPolicy` is the authority. It deliberately does
+*not* try to reproduce a strength score in PHP; it rejects the categorically
+bad, which is what a server can check without shipping a dictionary:
+
+- shorter than `PasswordPolicy::MIN_LENGTH` (8 — NIST SP 800-63B's floor;
+  composition rules like "must contain a symbol" are deliberately **not** used,
+  as they push people towards predictable substitutions),
+- one of the well-known leaked passwords,
+- built from fewer than four distinct characters (`aaaaaaaa`, `abababab`),
+- containing the user's own display name, email, or the part before the `@`.
+
+The nuance happens in the browser. `register.js` scores the password with
+zxcvbn through WordPress's own `password-strength-meter` script and refuses to
+submit below `PasswordPolicy::MIN_SCORE` (2 of 4 — "medium"; enough to stop a
+guessable password without demanding a passphrase to book a piano lesson). The
+thresholds reach JavaScript via `wp_localize_script()` from the same constants
+the server enforces, so the two cannot drift apart.
+
+The verdict is applied with `setCustomValidity()` on the password field rather
+than by disabling a button: the form has up to three submits plus a "Next" that
+already gates on `checkValidity()`, and an invalid field stops all of them
+without any needing to know why. zxcvbn's dictionary loads asynchronously, so
+the gate stays open until it arrives — the server is the check that always runs.

+account-scope questions describe a *student* — instrument, level, school — so
+they are asked of everyone being registered as one. Under `both` that is each
+student **and** the account holder, whose answers are stored against their own
+user id, not shared with anyone. Under `students` the account holder is not a
+student, so anything posted for them is ignored outright.
+
+Required answers are checked in two passes rather than one, so the error can say
+whose are missing: `both` would otherwise have to blame "each student" for the
+account holder's own blank field.
+
+Radios rather than checkboxes because the three answers are mutually exclusive:
+"both" only means anything as a third choice alongside the other two. Either
+student-bearing choice requires at least one student name.
+
+Anything unrecognised — a form posted without the field, an old cached page, a
+crafted request — is read as `self`, the choice that collects the least and
+grants the least. A missing radio must never be taken as "register these
+children".
+
+### The account holder as a student
+
+This replaced a single "I'm registering as a parent or guardian" checkbox, which
+could only say *whether there were children to add*. It could not say whether the
+**account holder** was a student, so `bookableStudents()` always offered them
+their own name and every guardian could book themselves a lesson nobody intended
+to sell.
+
+`students` now records `us_guardian_only = 1` and `bookableStudents()` leaves the
+account holder out. The flag is stored as the **negative** deliberately: every
+account predating the choice is a bookable student, and absence has to keep
+meaning exactly that, or the picker would silently stop offering people
+themselves on upgrade. `GuardianService::setGuardianOnly()` clears the key rather
+than writing `0`, so "not set" stays the one spelling of "yes, a student".
+
+One guard: a guardian-only account with **nobody linked to it** is still offered
+itself, because an empty picker is no way to book at all. They can put the
+account right from the profile page.

 Per child the form collects:
 - **Name** (required)
- **Date of birth** (optional, `us_date_of_birth` meta)
+- **Birth year** (required, `us_birth_year` meta) — a four-digit year between
+  1900 and the current year. `GuardianService::normaliseBirthYear()` is the one
+  definition of what counts, shared by the signup form's up-front validation and
+  by `createChild()`/`updateChild()` themselves, so a bad year is refused rather
+  than quietly discarded and a typo cannot leave a nonsense age on the record.
 - **Every account-scope registration question** (`Registration\Question`,
  `SCOPE_ACCOUNT`) — asked once per child, not once per guardian, because in
  practice they describe the student (instrument, level, school). The guardian
  answers them on the child's behalf; the answer row's `student_id` is the child.

+Name and birth year are marked required in the labels the same way a required
+question is, but the signup form **cannot** lean on the browser to enforce them:
+the child blocks are hidden until the parent/guardian box is ticked, and a
+`required` field inside a hidden container makes the form unsubmittable with no
+control the user can reach to fix. `register.js` therefore puts `required` on
+and takes it off along with the block itself (`[data-us-child-required]`), and
+the server checks regardless — which is what makes the rule hold with
+JavaScript off. The profile screen has no such problem: its forms are always
+visible, so the attribute is static there.

+# 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
