-# Backend context
-
-Read `ai/shared.md` first. This file covers backend-specific rules.
-
-## Project context
-
-**Stack:** PHP 8.4, Laravel 13, Inertia Laravel, PHPUnit, Larastan, Composer.
-
-**Location:** `backend/`.
-
-The application is still close to the Laravel starter structure. Do not
-introduce a domain architecture, repository layer, service layer, or other
-abstraction before the codebase and requested behavior justify it. Match
-existing Laravel conventions and inspect similar code before adding a new
-pattern.
-
-## Laravel patterns
-
-- Keep controllers thin. Put reusable business behavior in an appropriately
-  named application or domain class once the behavior warrants extraction.
-- Use dedicated request validation rather than validating substantial payloads
-  inline in controllers.
-- Let unexpected exceptions reach Laravel's exception handler. Catch only
-  exceptions that can be handled meaningfully at the current boundary.
-- Use Eloquent relationships and query scopes consistently rather than
-  duplicating query fragments.
-- Avoid speculative interfaces and abstractions with only one trivial
-  implementation.
-- Routes currently use Inertia, but the Vue client has not been scaffolded.
-  Do not add placeholder frontend assets as part of unrelated backend work.
-
-## Tests
-
-- Follow the existing PHPUnit organization under `tests/Unit/` and
-  `tests/Feature/`.
-- Prefer `PHPUnit\Framework\TestCase` when a test only exercises plain PHP.
-- Extend `Tests\TestCase` only when the test needs Laravel's container,
-  facades, database, routing, or HTTP kernel.
-- HTTP feature tests extend `Tests\TestCase`.
-- Use `RefreshDatabase` when a test reads or writes database state.
-- Assert behavior at the appropriate seam:
-  - Unit tests cover isolated business behavior and edge cases.
-  - Feature tests cover routing, middleware, validation, persistence, and
-    response shape.
-- Do not duplicate every business branch through the HTTP layer when unit
-  coverage already proves it. Feature tests should focus on wiring and the
-  public contract.
-
-## Test database
-
-- Development and runtime use PostgreSQL through the local Unix socket.
-- PHPUnit intentionally uses SQLite `:memory:` as configured in
-  `phpunit.xml`.
-- Feature tests are self-contained and do not require the process-compose
-  PostgreSQL service.
-- Never point `RefreshDatabase` tests at the development PostgreSQL database.
-- Keep mail set to the PHPUnit `array` transport unless a test explicitly
-  exercises a real mail integration.
-
-## PHP rules
-
-- Put imports at the top of the file. Do not use inline fully qualified class
-  names when a normal `use` statement is clearer.
-- Do not use arrow functions. Use regular anonymous functions.
-- Do not add default values to function or constructor parameters. Pass every
-  argument explicitly, including nullable arguments.
-- Use descriptive names for classes, methods, parameters, and local
-  variables.
-- Document exceptions with `@throws` when a caller is expected to handle
-  them.
-
-## Seeders
-
-- Keep `DatabaseSeeder` as the orchestrator.
-- Split substantial seed data into one seeder per domain concept and invoke
-  them in dependency order.
-- Do not add production repository or model APIs solely to make seeding
-  convenient.
-- Use existing lookup methods for cross-seeder relationships. When a group of
-  records only makes sense together, keep them in one seeder and retain local
-  references.
-
-## Migrations
-
-- Attainly is not in production yet.
-- While no production database exists, edit the original `create_*` migration
-  when changing a table instead of accumulating follow-up alter migrations.
-- Keep one migration file per table during this pre-production phase.
-- Rebuild the development database with:
-
-  ```sh
-  php artisan migrate:fresh --seed
-  ```
-
-- Once a production database exists, replace this policy with additive,
-  forward-only migrations.
-
-## Before completing backend work
-
-- Run the focused test during development.
-- Run `php artisan test` before completion.
-- Run the Composer lint and static-analysis scripts when their dependencies
-  are available.
-- Fix failures caused by the change. Report unrelated baseline failures
-  precisely rather than hiding them or expanding scope without authorization.

-# Frontend context
-
-Read `ai/shared.md` first. This file covers frontend-specific rules.
-
-## Current state
-
-The Vue frontend has not been scaffolded yet. The backend has Inertia Laravel
-installed and an Inertia route, but there is no `package.json`, Vue source
-tree, Vite configuration, or frontend test setup.
-
-- Do not create the frontend unless the user explicitly asks.
-- Do not invent a frontend directory, package manager, dependency version, or
-  command before the scaffold establishes it.
-- When the frontend is created, update this file with its actual paths,
-  package versions, scripts, and testing tools.
-
-## Vue conventions
-
-Apply these rules once a Vue 3 frontend exists:
-
-- Use the Composition API and `<script setup lang="ts">`.
-- Use PascalCase component filenames.
-- Keep page, component, composable, and store responsibilities distinct.
-- Prefer small components with explicit props and emitted events.
-- Keep component styles scoped unless the scaffold establishes a deliberate
-  global styling system.
-- Follow the routing and page conventions established by the chosen Inertia
-  or Vue Router scaffold. Do not mix the two approaches without an explicit
-  architectural reason.
-- Inspect similar files before introducing a new component, composable, store,
-  or data-access pattern.
-
-## TypeScript
-
-- Enable and preserve strict mode.
-- Do not use `any`. Model unknown external values as `unknown` and narrow or
-  validate them.
-- Derive types from runtime schemas when a schema library is adopted. Do not
-  maintain a hand-written type that can drift from its validation schema.
-- Validate payloads at trust boundaries, especially backend responses and
-  user-submitted forms.
-- Keep request and response types close to the API or store boundary that owns
-  them.
-- Add a path alias only when it is configured consistently in Vite,
-  TypeScript, tests, and Cypress.
-
-## State and API access
-
-- Use the state-management approach chosen by the scaffold consistently.
-- Keep server data fetching and transformation at an API/store boundary, not
-  scattered through presentation components.
-- Represent loading, empty, success, validation-error, and unexpected-error
-  states explicitly.
-- Do not cast unchecked JSON directly to an application interface.
-- Keep read and write payload types separate when their shapes differ.
-
-## Testing
-
-Use layered tests once the frontend test setup exists:
-
-- Unit tests cover pure transformations, composables, store logic, computed
-  values, and formatting.
-- Component tests cover rendering, events, form behavior, and conditional UI.
-- Cypress tests cover routing, multi-page flows, and request wiring.
-- Prefer the cheapest layer that proves the behavior.
-- Import test functions explicitly rather than relying on globals unless the
-  scaffold deliberately configures globals.
-- Build test data with small typed builders instead of repeated bare object
-  literals.
-
-## Frontend/backend test boundary
-
-- Mock backend requests in frontend tests.
-- A frontend test should verify how the UI consumes a response and which
-  request it sends, not retest Laravel's business rules.
-- Test backend persistence, validation, authentication, and mail behavior in
-  PHPUnit.
-- Keep mocked response bodies typed against the frontend's exported API or
-  store types.
-- When runtime schemas exist, parse mock-builder output through the same
-  schema so drift fails at the test boundary.
-
-## Before completing frontend work
-
-- Run the formatter, linter, type checker, unit tests, and Cypress scripts
-  defined by the frontend's `package.json`.
-- Do not substitute a hand-picked subset for the repository's eventual full
-  frontend gate.
-- If the frontend cannot run because the scaffold or a required service is
-  absent, report the precise environmental or baseline failure.

-# Shared rules
-
-Rules that apply to both backend and frontend work in this repository.
-Stack-specific guides (`backend-context.md`, `frontend-context.md`) extend
-these rules.
-
-## Project state
-
-- Attainly is in early development.
-- Attainly helps users break hierarchical goals into scheduled assignments,
-  complete daily work, and track progress toward a target date.
-- Schedule recalculation must preserve completed work while redistributing
-  unfinished assignments across the remaining dates.
-- Planned features in `README.md` are future ideas, not authorized scope.
-- The Laravel backend exists under `backend/`.
-- The Vue frontend has not been scaffolded yet. Do not create it unless the
-  user explicitly asks for that work.
-- PostgreSQL is the development and runtime database.
-- PHPUnit uses in-memory SQLite for isolated tests.
-
-## Process (TDD)
-
-0. Before editing any file, ensure you are working in a dedicated git
-   worktree, not the main checkout (`git status` and `git worktree list`).
-   If on `master`/`main` or in the main working directory, create a worktree
-   first (see Branching).
-1. Write the test first.
-2. Run the test to confirm it fails for the expected reason.
-3. Commit the failing test. The test commit must precede the implementation
-   commit, not merely appear earlier in the implementation diff.
-4. Implement the smallest change that makes the test pass.
-5. Run the test to confirm it passes.
-6. Commit the implementation.
-7. Repeat for each new behavior.
-
-Use judgment for changes that cannot meaningfully be test-driven, such as
-documentation-only edits or declarative environment configuration. Validate
-those changes with the most relevant parser, formatter, dry run, or check.
-
-## Running processes
-
-- The main checkout owns the canonical stack on the default ports. Assume it
-  is the user's stack. Do not start, restart, or stop it unless the user asks.
-- A worktree owns its own isolated stack. The flake shell hook assigns a
-  deterministic port offset and creates worktree-local PostgreSQL state.
-- Start a worktree stack from its root with `process-compose up`. For
-  non-interactive use, run `process-compose up -D` and stop it with
-  `process-compose down`.
-- Do not use `process-compose -t=false` for a detached stack. It can leave an
-  orphaned PostgreSQL process holding the data directory.
-- Non-interactive agent shells do not automatically load direnv. A bare
-  `process-compose`, `php artisan`, or database command from a worktree can
-  silently use default ports and target the main checkout.
-- Prefix worktree stack and database commands with `direnv exec <worktree>`.
-  Examples:
-
-  ```sh
-  direnv exec <worktree> process-compose up -D
-  direnv exec <worktree> process-compose down
-  direnv exec <worktree> php artisan migrate:fresh --seed
-  ```
-
-- Run backend commands from `backend/`, or explicitly change into it in the
-  command.
-- When a normally valid check fails because a required service is down,
-  surface the environmental failure. Do not skip the check or silently switch
-  to a different database or service.
-- PHPUnit is self-contained and uses in-memory SQLite. It does not require the
-  PostgreSQL stack unless a future test is explicitly designed as a real
-  PostgreSQL integration test.
-
-## Code style
-
-- Keep lines at or below 80 columns where practical. Do not split short,
-  readable lines unnecessarily.
-- Use explicit, descriptive variable names. Do not use single-letter or
-  unexplained abbreviated names.
-- Explore the codebase and inspect similar files before implementing a new
-  pattern.
-- Never use em dashes in code, comments, or docblocks. Use hyphens.
-- Always use braced control-statement bodies, including early returns:
-
-  ```ts
-  if (identifier === null) {
-    return null
-  }
-  ```
-
-## Git commit style
-
-- Use present-tense, imperative subjects: `add`, `create`, `wire`, `fix`,
-  `test`.
-- Keep subjects lowercase and short, normally three to six words.
-- Match patterns in the existing git history.
-- Do not add AI or tool coauthor trailers.
-- Add a body when the subject cannot explain non-obvious motivation or
-  multi-file coordination.
-- Wrap bodies at approximately 72 columns and separate them from the subject
-  with a blank line.
-
-## Git commits
-
-- Commit tests before implementation.
-- Keep one logical change per commit. A logical change may span multiple
-  files.
-- Commit each meaningful step rather than batching unrelated work.
-- Do not include drive-by formatter or linter changes. Restore them or land
-  them as a separate formatting commit.
-- If a check fails on untouched code, do not bundle an unrelated fix. Report
-  the pre-existing failure or handle it as its own explicitly scoped change.
-
-## Branching
-
-- Never implement features directly in the main checkout or on
-  `master`/`main`.
-- Use a dedicated worktree under
-  `<repo-root>/.worktrees/<branch>`.
-- Create it with:
-
-  ```sh
-  git worktree add \
-    "$(git rev-parse --show-toplevel)/.worktrees/<branch>" \
-    -b <branch>
-  ```
-
-- Use descriptive kebab-case branch names, optionally prefixed with a type
-  such as `feature/` or `fix/`.
-- Keep worktree names short, preferably no more than about 20 characters.
-  PostgreSQL Unix socket paths are limited in length.
-- Provision a fresh worktree through direnv:
-
-  ```sh
-  direnv allow <worktree>
-  direnv exec <worktree> true
-  ```
-
-- Never symlink `backend/vendor` or a future frontend's `node_modules` from
-  another checkout. Dependency paths and generated autoloaders must remain
-  worktree-local.
-
-Do not push anything. Make commits as the TDD workflow requires.
-
-## Before completing a change
-
-Run the smallest relevant checks while iterating, then run every repository
-gate affected by the change.
-
-### Backend
-
-- Run tests from `backend/` with `php artisan test`.
-- Run the Composer checks defined by `backend/composer.json` when their
-  dependencies are available:
-
-  ```sh
-  composer lint:check
-  composer types:check
-  composer test
-  ```
-
-- Do not claim a green gate when a command fails. If the failure predates the
-  change, report the precise baseline failure.
-
-### Frontend
-
-- The frontend does not exist yet. Once scaffolded, use the scripts defined in
-  its `package.json` for formatting, linting, type checking, unit tests, and
-  end-to-end tests.
-- Update `ai/frontend-context.md` when the actual scaffold, package manager,
-  and commands are known.
-
-### Environment and integration
-
-- For Nix or shell-hook changes, run `nix fmt` and `nix flake check`.
-- For service configuration changes, run `process-compose --dry-run`.
-- When a change affects runtime wiring, start the worktree's stack and verify
-  the relevant endpoint or service against that worktree.
-- If you started the stack only for validation, stop it before finishing.
