Confirmed (via @backup) the two-layer ignore model and wrote it down so it stops
getting re-discovered:
- BUILTIN_IGNORES (patterns.py) = the SEED that generates a new project's
.backupignore at register; never consulted at backup time.
- .backupignore (via load_spec) = the runtime source of truth. No static
fallback exists, so the seed is safety-critical — an empty .backupignore backs
up everything (.venv, node_modules, .git) and can crash the machine.
Added a 'How Ignores Work' README section + code comments on BUILTIN_IGNORES and
load_spec. Added logs/ to the seed so new projects exclude log dirs (prax .jsonl
output) by default, not just *.log files, with a test. seedgo @backup 100%.
