 # Changelog
 
-## [0.3.0](https://github.com/sbrow/envr/compare/v0.2.1...v0.3.0) (2026-06-16)
-
-Version 0.3.0 represents a significant departure (and improvement) for envr.
-The entire codebase was rewritten in [Odin](https://odin-lang.org/) (from Go).
-This reduced the binary size from over 17MB to under 600k, improved performance,
-and significantly reduced the number of project dependencies from 69 to just 2.
-
-### ⚠ BREAKING CHANGES
-
-* The encryption format of databases has changed. Age encryption is no longer supported, and no automatic migration path was implemented.
-
-### Features
-
-* All encryption/decryption now happens in-memory. ([fe2b256](https://github.com/sbrow/envr/commit/fe2b256bd61eaf551d53faf3893b473a64a94667))
-* Config can be loaded from any path with `--config-file (-c)` flag. ([4a26ee8](https://github.com/sbrow/envr/commit/4a26ee814591e6aab0eb99d2359d51b31011edfe))
-* Switched from age to libsodium. ([23b8c2d](https://github.com/sbrow/envr/commit/23b8c2dc671a23cf76cf6746b33806ded9381486))
-
-
-### Performance Improvements
-
-* Improved writer performance. ([365e914](https://github.com/sbrow/envr/commit/365e9149b1a738ac9119bb5f74dc7e047ecfed5b))

-# Test Coverage Plan
-
-## Current State
-
-- 104 tests, all passing
-- Strong coverage: crypto, ssh, db CRUD + env_file + update_dir, config save/load + paths, scan, features, cant_scan, parse_args, `-c`/`--config-file` flag
-- Misleading test files: `cmd_check_test`, `cmd_list_test`, `cmd_nushell_completion_test` don't test their namesake procs
-- Biggest remaining gap: all `cmd_*` handlers untested
-
-## Command handler tests
-
-Stdout will be captured by redirecting `os.stdout` to a pipe.
-
-### `cmd_version` (cmd_version.odin)
-- Test default output (prints VERSION)
-
-### `cmd_list` (cmd_list.odin)
-- Test TTY path: fixture DB with rows, capture table output
-- Test non-TTY path: capture JSON output, unmarshal and verify keys/values
-- Test empty DB: verify clean output (empty table or `[]`)
-
-### `cmd_backup` (cmd_backup.odin)
-- Test successful backup: valid path, verify `db_insert` called
-- Test missing file: verify error message
-- Test duplicate backup: verify rejection or update behavior
-
-### `cmd_remove` (cmd_remove.odin)
-- Test successful removal: existing entry, verify `db_delete` called
-- Test removal of non-existent entry: verify error or no-op
-
-### `cmd_restore` (cmd_restore.odin)
-- Test successful restore: entry exists in DB, verify file written to correct path
-- Test restore of missing entry: verify error
-- Test directory creation: restore to path with missing parent dirs
-
-## Hard to test (interactive / external deps)
-
-### `cmd_scan` (cmd_scan.odin)
-- Test with fixture git repo containing `.env` files
-- Test `find_unbacked` integration (already partially tested in `cmd_check_test.odin`)
-- Non-TTY JSON output path
-
-### `cmd_edit_config` (cmd_edit_config.odin)
-- Needs refactoring: extract `$EDITOR` parsing into testable helper (TODO 12)
-- Test multi-word editor values (`"code -w"`)
-- Test missing `$EDITOR`
-
-### `cmd_init` (cmd_init.odin)
-- Interactive prompt makes this hard
-- Needs refactoring: extract SSH key discovery and config generation into testable procs
-- Test `--force` flag behavior
-
-### `prompt.odin`
-- Needs refactoring to be testable
-- `render_options` could be tested if it accepted an `io.Writer`
-- `read_key` could be tested with a pipe/redirect instead of raw stdin
-- `multi_select` is end-to-end interactive, likely integration test only
-
-## Notes
-
-- DB integration tests should use in-memory SQLite (`:memory:`) where possible.
-- Temp dir fixtures should follow the pattern in `scan_test.odin`.
-- Tests that manipulate the `HOME` env var must use a mutex to prevent races with parallel test execution.

-1. Commands are still leaking.
+Note: These todos can wait until all the subcommands have been ported.
 
-28. **db.odin** — Inconsistencies in how struct vs sqlite are named.
+## HIGH
 
-29. Add color flag and support non colored output.
+1. [x] **table.odin:74-89** — Hand-rolled JSON output doesn't escape `"`, `\`, newlines. Reimplements `json.marshal` which is already imported in `cmd_list.odin`. Replace with `json.marshal`.
 
-30. Use text/tables for command output
+2. **db.odin:380-383, 405, 446** — `sqlite.bind_text` return values overwritten but never checked. A failed bind means `sqlite.step` operates on unbound params.
 
-2. Generate md and man pages again.
+3. **config.odin:52-54** — `os.user_home_dir` error silently ignored. If it fails, `home` is `""` and all paths become relative (`".envr"` instead of `"~/.envr"`).
 
-3. **db.odin:324-327** — Map iteration (`remote_set`) is non-deterministic. Same file can produce different JSON on each backup, causing spurious DB diffs. Sort remotes before storing.
+30. **cmd_sync.odin:46-50, 64-68** — Double `db_insert` when `BackedUp`: first insert on line 48, then `db_update_required` is also true for `BackedUp` so second insert runs on line 65. Redundant and wasteful.
 
-4. Make sure official path separators are used when appropriate, rather than '/'.
+## MEDIUM
 
-5. **cmd_restore.odin:20-30 & cmd_remove.odin:19-29** — Identical path-resolution block copy-pasted. `is_abs` guard is redundant since `filepath.abs` is a no-op on absolute paths. Extract a helper.
+4. **db.odin:29-35** — `make_temp_path` never calls `strings.builder_destroy`. Leaks builder buffer every call.
 
-6. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
+5. **db.odin:324-327** — Map iteration (`remote_set`) is non-deterministic. Same file can produce different JSON on each backup, causing spurious DB diffs. Sort remotes before storing.
 
-8. **config.odin:178** — `search_paths` silently ignores `os.user_home_dir` error. If home is empty, `~` isn't expanded. Same class of bug as issue 3.
+6. **db.odin:470-473** — `string_to_cstring` allocates via `strings.clone_to_cstring` and never frees. Called dozens of times across db operations.
 
-10. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
+7. **db.odin:470, 462** — Both `string_to_cstring` and `cstring_to_string` ignore allocation errors. A nil cstring gets passed to SQLite (UB).
 
-11. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.
+8. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
 
-12. **cmd_sync.odin:80, cmd_list.odin:33** — `make([]string, 2)` for table rows never freed. Leaks per row. Defer to memory pass.
+9. **features.odin:30-41** — `find_binary` uses `strings.join` instead of `filepath.join`, uses `os.stat` instead of checking executability, hardcodes `:` as PATH separator (wrong on Windows).
 
-13. Check for prealloc opportunities. i.e. `make([dynamic]string)` -> `make([dynamic]string, 5)`.
+10. **cmd_restore.odin:20-30 & cmd_remove.odin:19-29** — Identical path-resolution block copy-pasted. `is_abs` guard is redundant since `filepath.abs` is a no-op on absolute paths. Extract a helper.
 
-14. Add a text filter to the multi_select.
+11. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
 
-16. Add tests for untested commands.
+12. **cmd_edit_config.odin:27** — `$EDITOR` used as single binary name. Breaks for multi-word values like `"code -w"`. Needs `strings.fields()`.
 
-17. 2 scan tests silently skip when fd isn't installed, tests pass without actually testing anything. These should use #assert to be sure that fd is in path.
+33. **config.odin:178** — `search_paths` silently ignores `os.user_home_dir` error. If home is empty, `~` isn't expanded. Same class of bug as issue 3.
 
-19. add --format -f flag to commands that draw tables.
+35. **prompt.odin:124** — `make([dynamic]bool, len(options))` creates N zero-initialized elements. Works because `false` is the default, but same footgun as original issue 1. Should be `make([dynamic]bool, 0, len(options))`.
 
-20. Replace `testing.expect` calls with `testing.expect_value` calls where appropriate.
+## LOW
 
-21. Change struct field names from PascalCase to snake_case.
+14. [x] **db.odin:338-341** — Unnecessary `strings.clone` before `filepath.dir` (which already returns a slice into the input).
 
-23. procedures should be ordered by use, main at the top, then in the order they are called from main.
+15. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
 
-24. Shell completion
+16. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.

+# Windows Compatibility Guide
+
+This document outlines Windows compatibility issues and solutions for the envr project.
+
+## Critical Issues
+
+### 1. Path Handling Bug (MUST FIX)
+
+**File:** `app/env_file.go:209`
+
+**Issue:** Uses `path.Join` instead of `filepath.Join`, which won't work correctly on Windows due to different path separators.
+
+**Current code:**
+```go
+f.Path = path.Join(newDir, path.Base(f.Path))
+```
+
+**Fixed code:**
+```go
+f.Path = filepath.Join(newDir, filepath.Base(f.Path))
+```
+
+## External Dependencies
+
+The application relies on external tools that need to be installed separately on Windows:
+
+### Required Tools
+
+1. **fd** - Fast file finder
+   - Install via: `winget install sharkdp.fd` or `choco install fd`
+   - Alternative: `scoop install fd`
+
+2. **git** - Version control system
+   - Install via: `winget install Git.Git` or download from git-scm.com
+   - Usually already available on most development machines
+
+## Minor Compatibility Notes
+
+### File Permissions
+- Unix file permissions (`0755`, `0644`) are used throughout the codebase
+- These are safely ignored on Windows - no changes needed
+
+### Editor Configuration
+**File:** `cmd/edit_config.go:20-24`
+
+**Issue:** Relies on `$EDITOR` environment variable which is less common on Windows.
+
+**Current behavior:** Fails if `$EDITOR` is not set
+
+**Recommended improvement:** Add fallback detection for Windows editors:
+```go
+editor := os.Getenv("EDITOR")
+if editor == "" {
+    if runtime.GOOS == "windows" {
+        editor = "notepad.exe"  // or "code.exe" for VS Code
+    } else {
+        fmt.Println("Error: $EDITOR environment variable is not set")
+        return
+    }
+}
+```
+
+## Installation Instructions for Windows
+
+1. Install required dependencies:
+   ```powershell
+   winget install sharkdp.fd
+   winget install Git.Git
+   ```
+
+2. Fix the path handling bug in `app/env_file.go:209`
+
+3. Build and run as normal:
+   ```powershell
+   go build
+   .\envr.exe init
+   ```
+
+## Testing on Windows
+
+After applying the critical path fix, the core functionality should work correctly on Windows. The application has been designed with cross-platform compatibility in mind, using:
+
+- `filepath` package for path operations (mostly)
+- `os.UserHomeDir()` for home directory detection
+- Standard Go file operations
+
+## Summary
+
+- **1 critical bug** must be fixed for Windows compatibility
+- **2 external tools** need to be installed
+- **1 minor enhancement** recommended for better Windows UX
+- Overall architecture is Windows-compatible
