Fixes date command errors on macOS with Homebrew GNU coreutils:
- 'date: invalid option -- v' when GNU date runs BSD syntax
- 'syntax error in expression' when stat returns filesystem metadata
Changes:
- Replace uname-based detection with capability detection (try/fallback)
- Try GNU commands first, fall back to BSD, then ultimate fallbacks
- Add date -r fallback for file mtime (most portable)
This handles mixed environments where uname returns "Darwin" but
GNU coreutils are in PATH from Homebrew.

- Extend parse_json_response() to support both flat and Claude CLI formats
- Extract result, sessionId, and metadata fields
- Support metadata.files_changed, metadata.has_errors, completion_status
- Parse progress_indicators array for confidence boosting
- Add session management functions for continuity tracking:
- store_session_id(): Persist session with ISO timestamp
- get_last_session_id(): Retrieve stored session ID
- should_resume_session(): Check session validity (24-hour expiration)
- Add get_epoch_seconds() to date_utils.sh for cross-platform epoch time
- Auto-persist sessionId to .session_id file during response analysis
- Add 16 new TDD tests for Claude CLI format and session management
- Update documentation for v0.9.6 (239 tests total)
Test count: 239 (up from 223)
Add -u flag to GNU date command in get_iso_timestamp() to match
the macOS implementation and function documentation. Both platforms
now consistently return UTC timestamps in YYYY-MM-DDTHH:MM:SS+00:00
format.
Before: date -Iseconds (returned local time on Linux)
After: date -u -Iseconds (returns UTC on Linux)
Add cross-platform date utility library to handle differences between
GNU date (Linux) and BSD date (macOS). Fixes issues with:
- ISO 8601 timestamp formatting (-Iseconds flag)
- Date arithmetic operations (-d vs -v flags)
Changes:
- Created lib/date_utils.sh with get_iso_timestamp() and get_next_hour_time()
- Updated ralph_loop.sh to use date utilities (2 instances)
- Updated lib/circuit_breaker.sh to use date utilities (4 instances)
- Updated lib/response_analyzer.sh to use date utilities (1 instance)
All date operations now work consistently across both platforms without
modification. The utility automatically detects the OS and uses the
appropriate date command syntax.
Tested on Linux with GNU date - all syntax checks and integration tests pass.
