Instead of downloading pre-built binaries (which may require AVX2),
compile llama.cpp from source during installation. This ensures:
- Works on older CPUs (Sandy Bridge, Haswell, etc.)
- Uses GGML_NATIVE=ON to optimize for the current CPU
- Binary path updated to build/bin/llama-server
Reverts the AVX2 detection that was incorrectly disabling LLM.
- Add cpu_supports_avx2() function to check /proc/cpuinfo for AVX2 flag
- Skip LLM binary download on CPUs without AVX2 (pre-built llama.cpp requires it)
- Add runtime check for llama-server binary compatibility (catches 'Illegal instruction')
- Provide helpful error messages about alternatives (compile from source or use external API)
- Sandy Bridge (2nd gen i7) and older CPUs now gracefully skip local LLM
- Fix create_conn/establish_pg_connection to return Result instead of panicking
- Fix AppConfig::from_env to not require database access (circular dependency)
- Add #[cfg(test)] to AppState Default impl to prevent accidental panic
- Add extensive debug logging for Vault startup troubleshooting
- Remove Stdio::null() from start() to allow shell redirections to work
- Add direct vault start test in bootstrap for debugging
- Make Vault setup failure fatal (was silently continuing)
- Redirect Vault exec_cmd output to logs/vault.log
- Add stdout/stderr null pipes to component spawn in installer.rs
- Suppress output in run_commands() in facade.rs
- All component output now goes to respective log files in logs/
- Add state_channel field to XtreeUI for receiving AppState updates
- Add set_state_channel() method to enable async state communication
- Poll for AppState in event loop to initialize panels when ready
- UI now shows loading state instantly, logs stream in real-time
- Transitions to full interactive mode when AppState is received
- Disable TLS on Vault for local development (HTTP instead of HTTPS)
- Fix bot_configuration id column type mismatch (TEXT -> UUID)
- Add migration 6.1.1 to convert config table id columns to UUID
- Fix sync_config_csv_to_db to use UUID binding for id column
- Make start_all async with proper Vault startup sequence
- Sync default.gbai config.csv to existing 'Default Bot' from migrations
- Add diagnostic logging for config loading
- Change default LLM/embedding URLs from https to http for local dev
- Add create_vault_config() function to generate config.hcl with mTLS settings
- Configure Vault to require client certificate verification
- Generate client certificate for botserver in bootstrap
- Update .env to include mTLS paths (VAULT_CACERT, VAULT_CLIENT_CERT, VAULT_CLIENT_KEY)
- Remove unused import in tls.rs
