+EUROPEAN UNION PUBLIC LICENCE v. 1.2
+EUPL © the European Union 2007, 2016
+
+This European Union Public Licence (the ‘EUPL’) applies to the Work (as defined below) which is provided under the
+terms of this Licence. Any use of the Work, other than as authorised under this Licence is prohibited (to the extent such
+use is covered by a right of the copyright holder of the Work).
+The Work is provided under the terms of this Licence when the Licensor (as defined below) has placed the following
+notice immediately following the copyright notice for the Work:
+                          Licensed under the EUPL
+or has expressed by any other means his willingness to license under the EUPL.
+
+1.Definitions
+In this Licence, the following terms have the following meaning:
+— ‘The Licence’:this Licence.
+— ‘The Original Work’:the work or software distributed or communicated by the Licensor under this Licence, available
+as Source Code and also as Executable Code as the case may be.
+— ‘Derivative Works’:the works or software that could be created by the Licensee, based upon the Original Work or
+modifications thereof. This Licence does not define the extent of modification or dependence on the Original Work
+required in order to classify a work as a Derivative Work; this extent is determined by copyright law applicable in
+the country mentioned in Article 15.
+— ‘The Work’:the Original Work or its Derivative Works.
+— ‘The Source Code’:the human-readable form of the Work which is the most convenient for people to study and
+modify.
+— ‘The Executable Code’:any code which has generally been compiled and which is meant to be interpreted by
+a computer as a program.
+— ‘The Licensor’:the natural or legal person that distributes or communicates the Work under the Licence.
+— ‘Contributor(s)’:any natural or legal person who modifies the Work under the Licence, or otherwise contributes to
+the creation of a Derivative Work.
+— ‘The Licensee’ or ‘You’:any natural or legal person who makes any usage of the Work under the terms of the
+Licence.
+— ‘Distribution’ or ‘Communication’:any act of selling, giving, lending, renting, distributing, communicating,
+transmitting, or otherwise making available, online or offline, copies of the Work or providing access to its essential
+functionalities at the disposal of any other natural or legal person.
+
+2.Scope of the rights granted by the Licence
+The Licensor hereby grants You a worldwide, royalty-free, non-exclusive, sublicensable licence to do the following, for
+the duration of copyright vested in the Original Work:
+— use the Work in any circumstance and for all usage,
+— reproduce the Work,
+— modify the Work, and make Derivative Works based upon the Work,
+— communicate to the public, including the right to make available or display the Work or copies thereof to the public
+and perform publicly, as the case may be, the Work,
+— distribute the Work or copies thereof,
+— lend and rent the Work or copies thereof,
+— sublicense rights in the Work or copies thereof.
+Those rights can be exercised on any media, supports and formats, whether now known or later invented, as far as the
+applicable law permits so.
+In the countries where moral rights apply, the Licensor waives his right to exercise his moral right to the extent allowed
+by law in order to make effective the licence of the economic rights here above listed.
+The Licensor grants to the Licensee royalty-free, non-exclusive usage rights to any patents held by the Licensor, to the
+extent necessary to make use of the rights granted on the Work under this Licence.
+
+3.Communication of the Source Code
+The Licensor may provide the Work either in its Source Code form, or as Executable Code. If the Work is provided as
+Executable Code, the Licensor provides in addition a machine-readable copy of the Source Code of the Work along with
+each copy of the Work that the Licensor distributes or indicates, in a notice following the copyright notice attached to
+the Work, a repository where the Source Code is easily and freely accessible for as long as the Licensor continues to
+distribute or communicate the Work.
+
+4.Limitations on copyright
+Nothing in this Licence is intended to deprive the Licensee of the benefits from any exception or limitation to the
+exclusive rights of the rights owners in the Work, of the exhaustion of those rights or of other applicable limitations
+thereto.
+
+5.Obligations of the Licensee
+The grant of the rights mentioned above is subject to some restrictions and obligations imposed on the Licensee. Those
+obligations are the following:
+
+Attribution right: The Licensee shall keep intact all copyright, patent or trademarks notices and all notices that refer to
+the Licence and to the disclaimer of warranties. The Licensee must include a copy of such notices and a copy of the
+Licence with every copy of the Work he/she distributes or communicates. The Licensee must cause any Derivative Work
+to carry prominent notices stating that the Work has been modified and the date of modification.
+
+Copyleft clause: If the Licensee distributes or communicates copies of the Original Works or Derivative Works, this
+Distribution or Communication will be done under the terms of this Licence or of a later version of this Licence unless
+the Original Work is expressly distributed only under this version of the Licence — for example by communicating
+‘EUPL v. 1.2 only’. The Licensee (becoming Licensor) cannot offer or impose any additional terms or conditions on the
+Work or Derivative Work that alter or restrict the terms of the Licence.
+
+Compatibility clause: If the Licensee Distributes or Communicates Derivative Works or copies thereof based upon both
+the Work and another work licensed under a Compatible Licence, this Distribution or Communication can be done
+under the terms of this Compatible Licence. For the sake of this clause, ‘Compatible Licence’ refers to the licences listed
+in the appendix attached to this Licence. Should the Licensee's obligations under the Compatible Licence conflict with
+his/her obligations under this Licence, the obligations of the Compatible Licence shall prevail.
+
+Provision of Source Code: When distributing or communicating copies of the Work, the Licensee will provide
+a machine-readable copy of the Source Code or indicate a repository where this Source will be easily and freely available
+for as long as the Licensee continues to distribute or communicate the Work.
+Legal Protection: This Licence does not grant permission to use the trade names, trademarks, service marks, or names
+of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and
+reproducing the content of the copyright notice.
+
+6.Chain of Authorship
+The original Licensor warrants that the copyright in the Original Work granted hereunder is owned by him/her or
+licensed to him/her and that he/she has the power and authority to grant the Licence.
+Each Contributor warrants that the copyright in the modifications he/she brings to the Work are owned by him/her or
+licensed to him/her and that he/she has the power and authority to grant the Licence.
+Each time You accept the Licence, the original Licensor and subsequent Contributors grant You a licence to their contributions
+to the Work, under the terms of this Licence.
+
+7.Disclaimer of Warranty
+The Work is a work in progress, which is continuously improved by numerous Contributors. It is not a finished work
+and may therefore contain defects or ‘bugs’ inherent to this type of development.
+For the above reason, the Work is provided under the Licence on an ‘as is’ basis and without warranties of any kind
+concerning the Work, including without limitation merchantability, fitness for a particular purpose, absence of defects or
+errors, accuracy, non-infringement of intellectual property rights other than copyright as stated in Article 6 of this
+Licence.
+This disclaimer of warranty is an essential part of the Licence and a condition for the grant of any rights to the Work.
+
+8.Disclaimer of Liability
+Except in the cases of wilful misconduct or damages directly caused to natural persons, the Licensor will in no event be
+liable for any direct or indirect, material or moral, damages of any kind, arising out of the Licence or of the use of the
+Work, including without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, loss
+of data or any commercial damage, even if the Licensor has been advised of the possibility of such damage. However,
+the Licensor will be liable under statutory product liability laws as far such laws apply to the Work.
+
+9.Additional agreements
+While distributing the Work, You may choose to conclude an additional agreement, defining obligations or services
+consistent with this Licence. However, if accepting obligations, You may act only on your own behalf and on your sole
+responsibility, not on behalf of the original Licensor or any other Contributor, and only if You agree to indemnify,
+defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against such Contributor by
+the fact You have accepted any warranty or additional liability.
+
+10.Acceptance of the Licence
+The provisions of this Licence can be accepted by clicking on an icon ‘I agree’ placed under the bottom of a window
+displaying the text of this Licence or by affirming consent in any other similar way, in accordance with the rules of
+applicable law. Clicking on that icon indicates your clear and irrevocable acceptance of this Licence and all of its terms
+and conditions.
+Similarly, you irrevocably accept this Licence and all of its terms and conditions by exercising any rights granted to You
+by Article 2 of this Licence, such as the use of the Work, the creation by You of a Derivative Work or the Distribution
+or Communication by You of the Work or copies thereof.
+
+11.Information to the public
+In case of any Distribution or Communication of the Work by means of electronic communication by You (for example,
+by offering to download the Work from a remote location) the distribution channel or media (for example, a website)
+must at least provide to the public the information requested by the applicable law regarding the Licensor, the Licence
+and the way it may be accessible, concluded, stored and reproduced by the Licensee.
+
+12.Termination of the Licence
+The Licence and the rights granted hereunder will terminate automatically upon any breach by the Licensee of the terms
+of the Licence.
+Such a termination will not terminate the licences of any person who has received the Work from the Licensee under
+the Licence, provided such persons remain in full compliance with the Licence.
+
+13.Miscellaneous
+Without prejudice of Article 9 above, the Licence represents the complete agreement between the Parties as to the
+Work.
+If any provision of the Licence is invalid or unenforceable under applicable law, this will not affect the validity or
+enforceability of the Licence as a whole. Such provision will be construed or reformed so as necessary to make it valid
+and enforceable.
+The European Commission may publish other linguistic versions or new versions of this Licence or updated versions of
+the Appendix, so far this is required and reasonable, without reducing the scope of the rights granted by the Licence.
+New versions of the Licence will be published with a unique version number.
+All linguistic versions of this Licence, approved by the European Commission, have identical value. Parties can take
+advantage of the linguistic version of their choice.
+
+14.Jurisdiction
+Without prejudice to specific agreement between parties,
+— any litigation resulting from the interpretation of this License, arising between the European Union institutions,
+bodies, offices or agencies, as a Licensor, and any Licensee, will be subject to the jurisdiction of the Court of Justice
+of the European Union, as laid down in article 272 of the Treaty on the Functioning of the European Union,
+— any litigation arising between other parties and resulting from the interpretation of this License, will be subject to
+the exclusive jurisdiction of the competent court where the Licensor resides or conducts its primary business.
+
+15.Applicable Law
+Without prejudice to specific agreement between parties,
+— this Licence shall be governed by the law of the European Union Member State where the Licensor has his seat,
+resides or has his registered office,
+— this licence shall be governed by Belgian law if the Licensor has no seat, residence or registered office inside
+a European Union Member State.
+

+# gachi-cli
+
+Unified command-line interface and ecosystem automation binary for `gachi`.
+
+## Architectural Overview
+
+`gachi-cli` provides the turnkey CLI executable `gachi`, delivering:
+- **`gachi init`**: Declarative multi-package workspace generation from Dhall schemas or interactive prompts ([Note [CLI Ergonomics and Non-Destructive Initialization]](docs/notes/GACHI_DESIGN.md)).
+- **`gachi sync`**: Cross-repository harmonic synchronization (Phase 3).
+- **`gachi retrofit`**: Non-destructive codebase retrofitting and overlay (Phase 4).
+- **`gachi plan`**: Detached Git governance and snapshot ledger rollback (Phase 5).
+
+## Installation & Quick Start
+
+```bash
+# Build the CLI executable
+cabal build gachi-cli
+
+# Run gachi init to scaffold a new project
+cabal run gachi -- init my-project --desc "High-performance substrate"
+
+# Or initialize from a declarative Dhall schema
+cabal run gachi -- init --config packages/gachi-schema/dhall/example-project.dhall --target-dir ./tmp-proj
+```
+
+## CLI Commands & Subcommand Hierarchy
+
+| Subcommand | Flag Options | Description | Status |
+| :--- | :--- | :--- | :--- |
+| `gachi init` | `[NAME] [-c FILE] [-d DIR] [-m MODE] [--no-git] [--dry-run]` | Scaffolds turn-key standardized repository workspace | **ACTIVE** |
+| `gachi sync` | `[--target DIR] [--dry-run]` | Harmonically syncs formatting, linters, and hooks | Phase 3 |
+| `gachi retrofit` | `[--target DIR] [--dry-run]` | Non-destructively overlays canonical hierarchy | Phase 4 |
+| `gachi plan` | `[checkpoint\|diff\|log\|rollback]` | Detached Git plan store and snapshot rollback | Phase 5 |
+| `gachi version` | | Displays toolchain metadata and version stanzas | **ACTIVE** |
+
+## Invariants & Guarantees
+
+1. **Non-Destructive Safety:** By default, files are written under `FailOnExisting` mode to prevent overwriting existing assets. Dry-run mode (`--dry-run`) previews actions without touching disk.
+2. **Turnkey Git Governance:** Automatically executes `git init` and pins `core.hooksPath` to `.githooks` and `commit.template` to `.gitmessage`.
+3. **Five-Gate Physical Verification:** Skeletons immediately pass all 5 verification gates (`./bin/<project>-verify`).
+
+## Documentation
+
+- [`AGENTS.md`](../../AGENTS.md) — Advisory rules for AI coding assistants.
+- [`PLAN.md`](../../PLAN.md) — Strategic roadmap (Milestone 2.3).
+- [`docs/notes/GACHI_DESIGN.md`](../../docs/notes/GACHI_DESIGN.md) — Canonical design monograph and notes.
