-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-Fixin.me is a "quantified self" Rails 7.2.3 application for personal data tracking. Users define hierarchical **quantities** (metrics to track), **units** (with optional conversion hierarchies), and **readouts** (individual measurements). There is also a non-persistent **measurement** model used as a form wrapper.
-
-## Setup
-
-Configuration files are distributed as `.dist` templates — copy and customize before use:
-
-```bash
-cp config/application.rb.dist config/application.rb
-cp config/database.yml.dist config/database.yml
-cp config/puma.rb.dist config/puma.rb
-```
-
-```bash
-bundle config --local frozen true
-bundle config --local path .gem
-bundle config --local with mysql development test   # or: pg, sqlite
-bundle install
-RAILS_ENV=development bundle exec rails db:create db:migrate db:seed
-```
-
-## Common Commands
-
-```bash
-bundle exec rails s                                          # start server
-bundle exec rails test                                       # all unit/model/controller tests
-bundle exec rails test:system                                # all system tests (Capybara + Selenium)
-bundle exec rails test test/system/units_test.rb            # single test file
-bundle exec rails test --seed 64690 --name test_add_unit    # single test by name
-bundle exec rails db:seed:export                             # export default settings as seed file

-## Architecture
-
-### Data Model
-
- **Quantity** — hierarchical tree (self-referential `parent_id`). Cached `depth` and `pathname` fields are recomputed via recursive CTEs on write. Direct assignment to cached fields is blocked.
- **Unit** — optional hierarchy via `base_id` and `multiplier` for unit conversion. Multiplier precision/scale is validated by a custom validator.
- **Readout** — single measurement: `value` (IEEE 754 float), `quantity`, `unit`, `category`.
- **Measurement** — `ActiveModel::Model` form wrapper (not database-backed); bridges the readout creation form.
- **User** — Devise-managed with a status enum: `admin`, `active`, `restricted`, `locked`, `disabled`. Admins can disguise as other users.
-
-### Hierarchical Queries
-
-Both `Quantity` and `Unit` use recursive CTEs for tree traversal (ordered traversal, ancestors, progenies, common ancestors). `lib/core_ext/arel/` patches Arel to support CTE with `UPDATE`/`DELETE` statements, working around Rails issue #54658.
-
-### Custom Extensions (`lib/core_ext/`)
-
- **arel/** — CTE support for UPDATE/DELETE
- **active_model/** — precision/scale validator used by `Unit#multiplier`
- **active_record/** — `attr_cached` mechanism (see `ApplicationRecord`)
- **action_view/** — record identifier suffixes
- Miscellaneous: `Array#delete_bang`, `BigDecimal` scientific notation
-
-### Response Handling
-
-Controllers respond to both HTML and Turbo Stream formats. Errors during Turbo Stream requests trigger a redirect with flash rather than rendering inline, handled in `ApplicationController`.
-
-### Numeric Precision
-
-Readout values are stored as IEEE 754 double-precision floats (not fixed-point decimals). Rationale in `DESIGN.md`: biological values span many orders of magnitude; 15-digit float precision is sufficient and avoids conversion overhead.
-
-### Routes
-
-```
-measurements   GET/POST /measurements
-readouts       GET/POST /readouts, DELETE /readouts/:id/discard
-quantities     CRUD + POST /quantities/:id/reparent
-units          CRUD + POST /units/:id/rebase
-users          CRUD + POST /users/:id/disguise, POST /users/revert
-default/       namespace for default units import/export and admin panel
-root           → /units (authenticated), /sign_in (unauthenticated)
-```

-## Database Requirements
-
-The database must support:
- Recursive CTEs with `UPDATE`/`DELETE` (MySQL ≥ 8.0, PostgreSQL, or SQLite3)
- Decimal precision of 30+ digits

+
+### Database layer vs application layer data model constraints
+
+* database constraints are the final guard against data integrity corruption,
+    * they should safeguard against data referential integrity loss under _all_
+      data (not schema) manipulation scenarios, including application level
+      logic errors and direct data manipulation (e.g. through `dbconsole`),
+* application constraints can be as restrictive as database constraints or more,
+  but not less, as it doesn't serve any use case,
+    * proper application level constraints should prevent unhandled database
+      exception occurences, e.g `ActiveRecord::InvalidForeignKey` for operations
+      performed through Models (i.e. not `#delete_all` etc.)
+
+### User interface
+* values provided by user have to be exactly preserved, avoiding any precision
+  loss due to e.g. type casting
+    * when it's not possible to store value without information loss, feedback has to
+      be given at the time of entering value
+    * values can be received using either:
+        * `input[number]` - validates: number format, value against `[min]` and
+          `[max]` attributes; cannot validate precision (no `[pattern]` support);
+          or
+        * `input[text]` - can validate number format and precision with
+          `[pattern]`; cannot validate range (no `[min]`/`[max]` support),
+        * none of the above prevents misinterpretation of values between 0 and
+          Float::MIN as 0.0 - this has to be checked manually,
+        * assuming that user input with _precision > DIG_ is as rare as in
+          the range _(0, MIN)_, the decision is to choose input which requires
+          the least/simplest additional code.
