 # Configliere
 
-Functional configuration parser that validates all program inputs (config files,
-environment variables, CLI options) ahead of time using a single schema based on
-the [Standard Schema](https://standardschema.dev) spec.
+Configuration for programs.
 
-## Architecture
+## Current state
 
-Configliere is a parser-combinator library. Small parsers compose into larger
-ones. Every parser implements the `Parser` interface from `lib/types.ts` and
-returns an `Increment` — either `Done|Fail` for single-step parsers or
-`Next|Fail` for multi-step (phased) parsers.

-### Key design concepts

-- **Source tracking**: Every parsed value carries metadata about where it came
+Configliere is undergoing a ground-up rebuild. No implementation architecture is
+established yet. Design from the bottom up with small API sketches, exact type
+expectations, and tests before implementation. Do not carry architectural
+assumptions forward from pre-rebuild history.

 ### Testing
 
 - Framework: `@std/testing/bdd` (`describe`/`it`) with `@std/expect`
-- Schema library in tests: `arktype` (via `type()`)
-- Test helpers in `test/test-helpers.ts`: `parseOk()` and `parseNotOk()` wrap
-  `parseSync` with assertions
-- Tests live in `test/` and mirror `lib/` module names (e.g.
-  `test/field.test.ts`)

 ### Runtime and tooling
 
 - **Runtime**: Deno
 - **Registry**: JSR (`@frontside/configliere`)
-- **Linting**: `deno lint` (excludes `prefer-const` and `require-yield`)
-- **Testing**: `deno test`
-- **Examples**: Files in `examples/` must compile (`deno check`) and run
-  (`deno run`) without errors
+- **Linting**: `deno lint` (excludes `prefer-const`)
+- **Testing**: `deno task test`
 - **Build**: `deno task build:npm` (dnt) and `deno task build:jsr`
