Implement a generic BYOH mechanism that lets any ACP-speaking harness (Cursor, Pi, Amp, OpenClaw, Hermes, etc.) work with Buzz without maintaining separate backend code per harness type. Backend (Rust): - Add HarnessDefinition, HarnessSource, PRESET_HARNESSES (8 presets: cursor/omp/grok/opencode/kimi/amp/hermes/openclaw) + custom harness loading from ~/.config/buzz/custom-harnesses/ - warm_harness_registry_from_dir called at startup (before restore) and transactionally on save/delete; try_record_agent_command returns typed DANGLING_HARNESS_ID:<id> error — never silently falls to default - Full descriptor resolved at spawn/readiness/spawn_hash paths; definition env merges below Buzz-reserved vars; edit round-trip carries definition_env in catalog entry - All sweep paths (reap_dead_instance_agents, kill_stale_tracked_processes, receipt cleanup) use marker/receipt ownership — no name-gating - save_custom_harness validates before mutation; atomic write + old-file delete on rename; preset ids reserved in check_id_collision - buzz_sweep_owns_process cross-platform (no #[cfg(unix)] guard) Frontend (TypeScript): - Settings > Agents BYOH gallery: preset cards (Detected/Not-installed + docs link, no Add button), custom cards (full edit/delete) - ArgsEditor (repeatable rows) + EnvEditor (KEY=VALUE pairs) - HarnessManagementCard + harnessFormLogic.ts (21 behavior tests) - harnessGalleryLogic.ts (11 tests: detected-first sort, preset filtering) - Onboarding: actionable 'More harnesses...' button → Settings > Agents - PRESET_LOGOS bundled map; avatarUrl stripped from all surfaces Tests: +27 frontend / +20 Rust lib (registry lifecycle, env round-trip, sweep ownership, legacy-JSON serde, preset collision) Co-authored-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <pfleger.will@gmail.com>
