Expose active and last lifecycle command data on RuntimeSnapshot so frontend polling can render trustworthy lifecycle feedback without inferring from status alone.

Centralize duplicate start/stop blocking in runtime state helpers so save, start, and stop flows share the same command-result contract.

Keep restart-required save enforcement limited to connection_mode, model_path, addr, gpu_layers, and ctx_size to stay aligned with the existing backend runtime boundary.

RuntimeSnapshot includes active_command plus last_command_result for stable in-flight and terminal lifecycle messaging.

Lifecycle commands update terminal outcomes through helper functions instead of ad-hoc last_error-only handling.

Phase 2 Plan 01: Lifecycle Command Safety Summary

Runtime snapshot lifecycle metadata and guarded local start/stop/save outcomes at the Tauri runtime boundary

Accomplishments

Added serialized lifecycle command metadata to RuntimeSnapshot so backend snapshots now report both the active command and the last completed command result.
Centralized lifecycle result helpers and guard rules in runtime state so duplicate start/stop requests return stable blocked messages instead of silent no-ops.
Routed restart-required saves and lifecycle success/failure paths through one command-result contract while preserving the existing backend restart-impact field list.

Task 2: Guard conflicting lifecycle commands and preserve restart-impacting save rules - 67651bf (feat)

Files Created/Modified

tauri-app/src-tauri/src/runtime/types.rs - defines lifecycle command and result payloads on runtime snapshots.
tauri-app/src-tauri/src/runtime/state.rs - stores lifecycle metadata, shared guard helpers, and regression tests for blocked command behavior.
tauri-app/src-tauri/src/runtime/mod.rs - applies guard helpers to save/start/stop commands and records consistent lifecycle outcomes.

Decisions Made

Used snapshot-level lifecycle transport instead of separate command-specific responses so existing polling consumers can adopt the new contract incrementally.
Kept blocked lifecycle feedback in last_command_result while reserving last_error for actual runtime failures such as restart-required, spawn, health, and stop failures.
Preserved the restart-required field list exactly as planned and covered non-restart fields with regression tests.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Cleared latched active commands when config persistence fails

Found during: Task 2 (Guard conflicting lifecycle commands and preserve restart-impacting save rules)
Issue: Beginning a save or save-and-start command before persisting config could leave active_command stuck if save_runtime_config returned an error.
Fix: Added failure handling that records a failed lifecycle result, stores save_failed, and exits without leaving the runtime in an in-flight command state.
Files modified: tauri-app/src-tauri/src/runtime/mod.rs
Verification: cargo test --manifest-path "tauri-app/src-tauri/Cargo.toml" runtime:: and cargo check --manifest-path "tauri-app/src-tauri/Cargo.toml"
Committed in: 67651bf (part of task commit)

Total deviations: 1 auto-fixed (1 bug) Impact on plan: The auto-fix kept the new lifecycle contract trustworthy under save failures without expanding scope beyond the planned backend boundary.

Issues Encountered

The plan's verification command used cargo test -p tauri-app runtime::, but the Tauri crate is named forgelm-chat; verification succeeded via cargo test --manifest-path "tauri-app/src-tauri/Cargo.toml" runtime::.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Frontend lifecycle manager work can now read active_command and last_command_result directly from runtime snapshots.
Restart/apply UI work can rely on the backend restart-required contract staying limited to connection_mode, model_path, addr, gpu_layers, and ctx_size.

Self-Check: PASSED

Summary file exists at .planning/phases/02-lifecycle-command-safety/02-01-SUMMARY.md.
Verified commit hashes 217e265, cf73eb2, 581b81b, and 67651bf are present in git history.
