+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Git Commit Guidelines
+
+**IMPORTANT**: When creating commit messages, do not attribute commits to yourself (Claude). Commit messages should reflect the work being done without AI attribution in the message body. The standard Co-Authored-By trailer is acceptable.
+
+## What This Repo Is
+
+**pgxntool-test-template** is a minimal "dummy" PostgreSQL extension that serves as a test subject for **../pgxntool-test/** (the test harness).
+
+This repo is **NOT intended to be used as a real extension**. It exists solely to:
+1. Demonstrate proper pgxntool integration
+2. Provide a known-good starting state for automated tests
+3. Serve as a template that tests clone and manipulate
+
+## The Three-Repository Pattern
+
+- **../pgxntool/** - The build framework (embedded via git subtree)
+- **../pgxntool-test/** - The test harness that clones this repo and validates pgxntool
+- **pgxntool-test-template/** (this repo) - The test subject (minimal working extension)
+
+**Testing flow**: pgxntool-test clones this repo → runs pgxntool operations → validates outputs
+
+## Repository Structure
+
+```
+pgxntool-test-template/
+├── pgxntool-test.control   # Extension control file
+└── t/                      # Embedded pgxntool + extension code
+    ├── doc/
+    │   └── TEST_DOC.asc    # Sample documentation
+    ├── sql/
+    │   └── pgxntool-test.sql    # Extension SQL (simple add function)
+    ├── test/
+    │   └── input/
+    │       └── pgxntool-test.source  # Test file (loads extension, runs simple test)
+    └── .gitignore
+```
+
+**Important**: This repo has a subdirectory structure (everything in `t/`) which is unusual. Most real extensions using pgxntool would have files at the root level. This structure is specific to the testing setup.
+
+## What the Extension Does
+
+The extension provides a single trivial function:
+
+```sql
+CREATE FUNCTION "pgxntool-test"(a int, b int) RETURNS int
+```
+
+It simply adds two integers. The function is intentionally minimal because the focus is testing pgxntool's build/test infrastructure, not extension functionality.
+
+## How pgxntool-test Uses This Repo
+
+The test harness (**../pgxntool-test/**) performs these operations:
+
+1. **Clone**: `git clone` this repo to a temp directory
+2. **Isolate**: Rewire git remote to a fake repo (prevents accidental pushes)
+3. **Inject pgxntool**: Either via `git subtree add` or `rsync` (if testing uncommitted changes)
+4. **Run setup**: Execute `pgxntool/setup.sh`
+5. **Build/Test**: Run `make`, `make test`, `make dist`, etc.
+6. **Validate**: Compare outputs against expected results
+
+## Expected Test Behavior
+
+When used in tests, this extension should:
+- Successfully run `pgxntool/setup.sh` (when repo is clean)
+- Build without errors
+- Pass its single test (verifying 1 + 2 = 3)
+- Generate proper META.json from META.in.json template
+- Create distribution .zip file
+- Generate HTML from TEST_DOC.asc
+
+## Maintenance Guidelines
+
+**Changes to this repo should be rare** because:
+1. It's a test fixture - stability is more important than features
+2. Changes may require updating expected outputs in **../pgxntool-test/expected/**
+3. It should remain minimal to make test failures easy to diagnose
+
+**When to modify**:
+- Adding test coverage for new pgxntool features
+- Fixing bugs in the test fixture itself
+- Updating for PostgreSQL version compatibility
+
+**When modifying**:
+1. Make changes here
+2. Run full test suite: `cd ../pgxntool-test && make test`
+3. Verify all tests still pass OR update expected outputs if intentional
+4. Document what changed and why
+
+## File Details
+
+### pgxntool-test.control
+Standard PostgreSQL extension control file. Specifies:
+- Extension name: `pgxntool-test`
+- Default version, comment, etc.
+
+### t/sql/pgxntool-test.sql
+The extension's SQL code. Contains a simple addition function that works on PostgreSQL 9.1+ (avoids named parameters for old version compatibility).
+
+### t/test/input/pgxntool-test.source
+Test file using pg_regress format:
+- Loads pgTap via pgxntool's setup infrastructure
+- Loads extension deps via `test/deps.sql`
+- Creates extension `pgxntool-test`
+- Runs one test verifying the add function works
+- Uses pgTap `plan()`, `is()`, and `finish()` functions
+
+### t/doc/TEST_DOC.asc
+Minimal Asciidoc file for testing document generation. pgxntool should auto-detect and convert to HTML.
+
+## Not Present (But Would Be in Real Extensions)
+
+Real extensions using pgxntool typically have:
+- `Makefile` (just `include pgxntool/base.mk`)
+- `META.in.json` (metadata template)
+- `src/*.c` (optional C code)
+- Actual functionality beyond a trivial add function
+- Comprehensive test suite
+- Real documentation
+
+These are omitted or minimal here because they're created/validated by the test harness itself.
+
+## Related Repositories
+
+- **../pgxntool/** - The build framework being tested
+- **../pgxntool-test/** - The test harness that uses this repo as a test subject
+
+## Special Notes
+
+- **Git subtree**: This repo expects pgxntool to be added via `git subtree add -P pgxntool`
+- **Clean repo required**: Tests verify that setup.sh properly rejects dirty repos
+- **Version compatibility**: SQL code avoids features requiring newer PostgreSQL versions
+- **Fake asciidoc**: Tests may use a fake asciidoc implementation to avoid dependency variability

Subject: [PATCH 09/10] Update template structure for pgxntool changes

Update for pgxntool commit c7b5705 (pg_tle version changes and lib.sh):
- Add `.DS_Store` to `.gitattributes` export-ignore rules

Reorganize template structure to match test expectations:
- Move `pgxntool-test.control` to `t/` directory
- Remove `.gitignore` files (pgxntool's `_.gitignore` handles this)

These changes align with the new test infrastructure in pgxntool-test
that copies only files from `t/` directory to test repository root.

Subject: [PATCH 10/10] Deprecate repository - template files moved to
 pgxntool-test

Remove template files (t/ directory) - they have been moved to
pgxntool-test/template/. The test harness now creates fresh test
repositories directly from those template files, eliminating the need
for a separate template repository.

Add deprecation notices in CLAUDE.md and README.md explaining that this
repository is no longer used and exists only to preserve commit history.

The pgxntool project now uses a simpler two-repository pattern:
- pgxntool/ - Framework code
- pgxntool-test/ - Test harness with template files

-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+## Repository Status: DEPRECATED
 
-## Git Commit Guidelines
+**This repository is deprecated and no longer used.** It is kept only to preserve its commit history.
 
-**IMPORTANT**: When creating commit messages, do not attribute commits to yourself (Claude). Commit messages should reflect the work being done without AI attribution in the message body. The standard Co-Authored-By trailer is acceptable.
+## What Happened
 
-## What This Repo Is
+The template extension files that used to live in this repository have been moved to `../pgxntool-test/template/`. The test harness now creates fresh test repositories directly from that template directory, eliminating the need for a separate template repository.
 
-**pgxntool-test-template** is a minimal "dummy" PostgreSQL extension that serves as a test subject for **../pgxntool-test/** (the test harness).
+## Migration
 
-This repo is **NOT intended to be used as a real extension**. It exists solely to:
-1. Demonstrate proper pgxntool integration
-2. Provide a known-good starting state for automated tests
-3. Serve as a template that tests clone and manipulate
+If you need the template files, they are now located at:
+- **../pgxntool-test/template/**
 
-## The Three-Repository Pattern
+The test harness (`../pgxntool-test/`) contains all testing infrastructure and template files in a single repository.
 
-- **../pgxntool/** - The build framework (embedded via git subtree)
-- **../pgxntool-test/** - The test harness that clones this repo and validates pgxntool
-- **pgxntool-test-template/** (this repo) - The test subject (minimal working extension)
+## Two-Repository Pattern
 
-**Testing flow**: pgxntool-test clones this repo → runs pgxntool operations → validates outputs
+The pgxntool project now uses a simpler two-repository pattern:
 
-## Repository Structure
+1. **../pgxntool/** - The framework code that gets embedded into extension projects
+2. **../pgxntool-test/** - The test harness (includes template files in `template/` directory)
 
-```
-pgxntool-test-template/
-├── pgxntool-test.control   # Extension control file
-└── t/                      # Embedded pgxntool + extension code

-    │       └── pgxntool-test.source  # Test file (loads extension, runs simple test)
-    └── .gitignore
-```
+## Historical Context
 
-**Important**: This repo has a subdirectory structure (everything in `t/`) which is unusual. Most real extensions using pgxntool would have files at the root level. This structure is specific to the testing setup.
-
-## What the Extension Does
-
-The extension provides a single trivial function:
-
-```sql
-CREATE FUNCTION "pgxntool-test"(a int, b int) RETURNS int
-```
-
-It simply adds two integers. The function is intentionally minimal because the focus is testing pgxntool's build/test infrastructure, not extension functionality.
-
-## How pgxntool-test Uses This Repo
-
-The test harness (**../pgxntool-test/**) performs these operations:
-
-1. **Clone**: `git clone` this repo to a temp directory
-2. **Isolate**: Rewire git remote to a fake repo (prevents accidental pushes)
-3. **Inject pgxntool**: Either via `git subtree add` or `rsync` (if testing uncommitted changes)
-4. **Run setup**: Execute `pgxntool/setup.sh`
-5. **Build/Test**: Run `make`, `make test`, `make dist`, etc.
-6. **Validate**: Compare outputs against expected results
-
-## Expected Test Behavior
-
-When used in tests, this extension should:
-- Successfully run `pgxntool/setup.sh` (when repo is clean)
-- Build without errors
-- Pass its single test (verifying 1 + 2 = 3)
-- Generate proper META.json from META.in.json template
-- Create distribution .zip file
-- Generate HTML from TEST_DOC.asc
-
-## Maintenance Guidelines
-
-**Changes to this repo should be rare** because:
-1. It's a test fixture - stability is more important than features
-2. Changes may require updating expected outputs in **../pgxntool-test/expected/**
-3. It should remain minimal to make test failures easy to diagnose
-
-**When to modify**:
-- Adding test coverage for new pgxntool features
-- Fixing bugs in the test fixture itself
-- Updating for PostgreSQL version compatibility
-
-**When modifying**:
-1. Make changes here
-2. Run full test suite: `cd ../pgxntool-test && make test`
-3. Verify all tests still pass OR update expected outputs if intentional
-4. Document what changed and why
-
-## File Details
-
-### pgxntool-test.control
-Standard PostgreSQL extension control file. Specifies:
-- Extension name: `pgxntool-test`
-- Default version, comment, etc.
-
-### t/sql/pgxntool-test.sql
-The extension's SQL code. Contains a simple addition function that works on PostgreSQL 9.1+ (avoids named parameters for old version compatibility).
-
-### t/test/input/pgxntool-test.source
-Test file using pg_regress format:
-- Loads pgTap via pgxntool's setup infrastructure
-- Loads extension deps via `test/deps.sql`
-- Creates extension `pgxntool-test`
-- Runs one test verifying the add function works
-- Uses pgTap `plan()`, `is()`, and `finish()` functions
-
-### t/doc/TEST_DOC.asc
-Minimal Asciidoc file for testing document generation. pgxntool should auto-detect and convert to HTML.
-
-## Not Present (But Would Be in Real Extensions)
-
-Real extensions using pgxntool typically have:
-- `Makefile` (just `include pgxntool/base.mk`)
-- `META.in.json` (metadata template)
-- `src/*.c` (optional C code)
-- Actual functionality beyond a trivial add function
-- Comprehensive test suite
-- Real documentation
-
-These are omitted or minimal here because they're created/validated by the test harness itself.

-## Related Repositories
-
-- **../pgxntool/** - The build framework being tested
-- **../pgxntool-test/** - The test harness that uses this repo as a test subject
-
-## Special Notes
-
-- **Git subtree**: This repo expects pgxntool to be added via `git subtree add -P pgxntool`
-- **Clean repo required**: Tests verify that setup.sh properly rejects dirty repos
-- **Version compatibility**: SQL code avoids features requiring newer PostgreSQL versions
-- **Fake asciidoc**: Tests may use a fake asciidoc implementation to avoid dependency variability
+This repository previously served as a minimal "dummy" PostgreSQL extension used as a test subject. Tests would clone this repository and manipulate it to validate pgxntool's functionality. This approach has been replaced with a simpler method of creating fresh test repositories from template files stored directly in the test harness.

+# pgxntool-test-template
+
+## ⚠️ DEPRECATED REPOSITORY
+
+**This repository is no longer used and exists only to preserve its commit history.**
+
+## What Happened
+
+The template extension files that used to live here have been moved to:
+- **[pgxntool-test/template/](https://github.com/decibel/pgxntool-test/tree/master/template)**
+
+The test harness now creates fresh test repositories directly from that template directory, eliminating the need for a separate template repository.
+
+## Current Architecture
+
+The pgxntool project now uses a two-repository pattern:
+
+1. **[pgxntool](https://github.com/decibel/pgxntool)** - The framework code
+2. **[pgxntool-test](https://github.com/decibel/pgxntool-test)** - The test harness with template files
+
+## Migration Guide
+
+If you were using this repository:
+- Template files are now in `pgxntool-test/template/`
+- Tests create repositories directly from those template files
+- No changes needed to existing workflows using `pgxntool-test`
+
+## Historical Context
+
+This repository served as a minimal PostgreSQL extension that was cloned and manipulated during testing. The approach has been simplified to use template files stored directly in the test harness repository.
