 # Implementation Plan
 
-- [ ] 1. Foundation: rc-file path resolution and line-loading capability
+- [x] 1. Foundation: rc-file path resolution and line-loading capability
 - [x] 1.1 Implement rc-file path resolution following XDG precedence, with unit tests
   - Resolve the rc-file location using the XDG config variable when it is set and non-empty
   - Fall back to the home-directory XDG default when that variable is unset or empty, and to "no resolvable path" when neither variable is usable

   - Observable: a unit test run demonstrates every line is processed when the runner keeps succeeding, remaining lines are skipped the first time the runner signals a stop, the runner is never invoked when the file is absent, and a line well beyond a typical small fixed-buffer size (e.g. >4KB) reaches the runner intact and unsplit

+- [x] 2. Core: xce_test startup integration
 - [x] 2.1 Add a flag that skips rc-file loading for a single invocation
   - Register the flag with xce_test's existing command-line option parsing so it is documented in xce_test's own help output
   - When the flag is given, record that rc-file loading should be skipped for this run

-- [ ] 3. Validation: end-to-end behavior against the built binary
+- [x] 3. Validation: end-to-end behavior against the built binary
 - [x] 3.1 Verify rc-file discovery, loading, and skip-flag behavior end-to-end
   - Scenario: a valid rc file's settings/context take effect in both a piped run and an interactive run
   - Scenario: the skip flag leaves default settings untouched even with a valid rc file present
