Conversation
Adds `fava-trails get <scope>` with three modes: - Default: output latest non-superseded thought content to stdout - `--list`: list child scope names (for directory-style enumeration) - `--exists`: exit 0/1 for existence checks (no output) - `--with-frontmatter`: include YAML frontmatter in output Strict stdout hygiene — only requested content goes to stdout, all errors/diagnostics go to stderr. This enables reliable parsing by tools like porch that consume stdout with regex. Spec 559: Porch FAVA Trails Artifact Resolver Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Make --list and --exists mutually exclusive (argparse group) - Use is_dir() instead of exists() before directory operations Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
