 ## Current State
 
-- 60 tests, all passing
+- 101 tests, all passing
-- Strong coverage: crypto (100%), ssh (80%), scan, features
+- Strong coverage: crypto (100%), ssh (90%), db CRUD + env_file + update_dir, config save/load + paths, scan, features, cant_scan, parse_args
 - Misleading test files: `cmd_check_test`, `cmd_list_test`, `cmd_nushell_completion_test` don't test their namesake procs
-- Biggest gap: `db.odin` (15/21 procs untested), all `cmd_*` handlers untested, `parse_args` untested
+- Biggest remaining gap: all `cmd_*` handlers untested
 
-## Tier 1 — Easy wins (pure functions, minimal setup)
+## Next: `load_config` / `save_config` path param + `-c`/`--config-file` flag
+- Refactor `load_config(path: string = "")` and `save_config(cfg, force, path: string = "")` — empty string defaults to `~/.envr/config.json`
+- Add `-c`/`--config-file` to `parse_args` (now testable)
+- Wire through `main.odin` so commands receive the config path
+- Unblocks command handler tests with fixture configs
 
-### 1. `render_table` (table.odin)
+## Command handlers (need DB + filesystem fixtures)
-- Follow existing `render_json_rows` test pattern
-- Test cases: normal data (verify box-drawing chars, column alignment), empty rows, wide unicode, single column
-- Assert against `strings.Builder` output
 
-### 2. `parse_args` (cli.odin)
+### `cmd_version` (cmd_version.odin)
-- Test cases: bare command, `--flag value`, `-f value`, positional args, `--help`/`-h`, unknown command, no args (prints usage), flag without value (error)
-- High value — this is the entry point for all command dispatch
-
-### 3. `is_encrypted_key` (ssh.odin)
-- Test cases: encrypted key (returns true), unencrypted key (returns false), RSA key, malformed key
-- Fills last gap in ssh.odin
-
-## Tier 2 — High value, medium effort (fixtures exist)
-
-### 4. `db.odin` CRUD layer
-Largest gap in the project. Infrastructure already in `db_integration_test.odin` (`fixture_key`, `fixture_db_path`, in-memory DB setup).
-
-Procs to test:
-- `db_open` / `db_close` — open in-memory DB, verify handle valid
-- `db_insert` — insert a row, verify it persists
-- `db_fetch` — fetch existing row, fetch missing row (returns false)
-- `db_delete` — delete existing row (returns true), delete missing row (returns false)
-- `db_list` — list multiple rows, empty DB
-- `db_vacuum_to_file` — vacuum to temp file, verify file exists and is non-empty
-
-Test pattern: create in-memory DB via `db_open`, insert fixture rows, query and assert, `defer db_close`.
-
-### 5. `load_config` / `save_config` (config.odin)
-- `save_config`: write a `Config` to temp dir, verify file exists and contents are valid JSON
-- `load_config`: read back a config written by `save_config`, round-trip assert
-- `load_config` error case: missing file returns error
-- Need a temp dir fixture (pattern exists in `scan_test.odin`)
-
-## Tier 3 — Command handlers (need DB + filesystem fixtures)
-
-### 6. `cmd_version` (cmd_version.odin)
 - Test default output (prints VERSION)
-- Test `--long`/`-l` flag output
 - Capture stdout, assert content
 
-### 7. `cmd_list` (cmd_list.odin)
+### `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 `[]`)
 
-### 8. `cmd_backup` (cmd_backup.odin)
+### `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
 
-### 9. `cmd_remove` (cmd_remove.odin)
+### `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
 
-### 10. `cmd_restore` (cmd_restore.odin)
+### `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_deps` (cmd_deps.odin)
 - Needs `git` and/or `fd` in PATH
 - Test TTY and non-TTY paths
 - Skip if dependencies not available (with `#assert` like TODO 28 suggests)
 
-### 12. `cmd_scan` (cmd_scan.odin)
+### `cmd_scan` (cmd_scan.odin)
 - Needs `fd` installed
 - 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
 
-### 13. `cmd_edit_config` (cmd_edit_config.odin)
+### `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`
 
-### 14. `cmd_init` (cmd_init.odin)

 - Needs refactoring: extract SSH key discovery and config generation into testable procs
 - Test `--force` flag behavior
