hardened install behavior and exported testable helpers. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/tasks.md` - marked T007 complete. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/implementation-notes.md` - recorded progress. **BQC Fixes**: * Trust boundary enforcement: existing settings are parsed as untrusted JSON and must be plain objects. * State freshness on re-entry: repeated installs replace managed entries instead of duplicating them. * Failure path completeness: malformed settings preserve a backup and produce a caller-visible result. *** ### Task T006 - Create Browser Opener Helper **Started**: 2026-05-29 04:08 **Completed**: 2026-05-29 04:09 **Duration**: 1 minute **Notes**: * Added platform-specific opener command selection for macOS, Windows, and Linux. * Added bounded opener timeout and a reusable manual URL fallback message. **Files Changed**: * `apps/cli/src/lib/browser.js` -

recorded progress. **BQC Fixes**: * Failure path completeness: opener failures and timeouts return structured results for caller-visible fallback output. * External dependency resilience: browser command waits are bounded. *** ### Task T005 - Create Lifecycle Helper **Started**: 2026-05-29 04:05 **Completed**: 2026-05-29 04:08 **Duration**: 3 minutes **Notes**: * Added runtime-root discovery and workspace launch-script validation for the current npm workspace. * Added bounded health probes, port and URL normalization, lifecycle state inspection, managed start, managed stop, and browser-open target resolution. * Added daemon process ownership metadata so stop paths can refuse a PID that is not the recorded CLI-managed process when Linux process metadata is available. **Files Changed**: * `apps/cli/src/lib/lifecycle.js` - added lifecycle facade for launch, stop, PID state, health, workspace, and URL behavior. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/tasks.md` - marked T005 complete. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/implementation-notes.md` - recorded progress. **BQC Fixes**: * Resource cleanup: foreground starts register bounded signal cleanup and clear PID state on exit. * Duplicate action prevention: start uses lifecycle locking and live PID checks before spawning. * External dependency resilience: health probes have bounded timeouts and explicit failure states. * Error information boundaries: lifecycle state stores roots for diagnostics but avoids prompts, command output, tokens, and payload contents. *** ### Task T004 - Extend Local File Helpers **Started**: 2026-05-29 04:04 **Completed**: 2026-05-29 04:05 **Duration**: 1 minute **Notes**: * Added managed PID, lifecycle config, and project-root state helpers under the FactionOS home directory. * Added stale PID cleanup and port lookup helpers that tolerate malformed or missing local state. * Added a temp-file-plus-rename compatible lifecycle config path and a short-lived lock helper for duplicate start prevention. **Files Changed**: * `apps/cli/src/lib/localFiles.js` - added lifecycle state, PID, project-root, port, and lock helpers. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/tasks.md` - marked T004 complete. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/implementation-notes.md` -

marked T001 complete. * `.spec_system/specs/phase01-session03-cli-lifecycle-parity/implementation-notes.md` - recorded verification details. *** ## Task Log ### 2026-05-29 - Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available * [x] Directory structure ready *** --- # Agent Instructions This documentation is published with GitBook.
