Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available * [x] Directory structure ready * [x] Package scope confirmed for `apps/server` and `packages/protocol` *** ### Task T001 - Verify prerequisites, completed-session state, and package scope **Started**: 2026-05-31 13:20 **Completed**: 2026-05-31 13:21 **Duration**: 1 minute **Notes**: * Ran deterministic spec analysis; current session resolves to `phase10-session03-server-ingest-codex-lifecycle`. * Confirmed Phase 10 Session 01 and Session 02 are completed in spec state. * Verified package prerequisites for `apps/server` and `packages/protocol`. * Reviewed session PRD scope and confirmed no external credentials, hosted services, or database setup are required. **Files Changed**: * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/implementation-notes.md` - Created implementation log. * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/tasks.md` - Marked T001 complete. **BQC Fixes**: * N/A - setup verification only. *** ### Task T002 - Review server ingest normalization, event routing, and Codex hook payload shapes **Started**: 2026-05-31 13:21 **Completed**: 2026-05-31 13:22 **Duration**: 1 minute **Notes**: * Reviewed `apps/server/src/lib/eventIngest.ts` and `apps/server/src/routes/event.ts`. * Identified existing gaps: no `tool_name` alias, no `turn_id` alias, no `codex-cli` CLI acceptance, and no `SubagentStart` named dispatch branch. * Reviewed `apps/hooks/tests/hookRuntime.test.js` and hook handlers for sanitized Codex SessionStart, UserPromptSubmit, Bash, PermissionRequest, SubagentStart, apply\_patch, and MCP-shaped payloads. **Files Changed**: * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/implementation-notes.md` - Logged server review. * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/tasks.md` - Marked T002 complete. **BQC Fixes**: * N/A - source review only. *** ### Task T003 - Review protocol ingest and hero CLI contracts for Codex-safe fields **Started**: 2026-05-31 13:22 **Completed**: 2026-05-31 13:23 **Duration**: 1 minute **Notes**: * Reviewed `packages/protocol/src/ingest.ts` and `packages/protocol/src/heroes.ts`. * Confirmed protocol already owns `codex-cli` in `HeroCli`, while ingest metadata still needs explicit snake\_case Codex aliases. * Reviewed `packages/protocol/tests/ingest.test.ts` for existing provider-neutral hook and compact metadata coverage. **Files Changed**: * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/implementation-notes.md` - Logged protocol review. * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/tasks.md` - Marked T003 complete. **BQC Fixes**: * N/A - source review only. *** ### Task T004 - Extend protocol ingest payload contract for bounded Codex aliases **Started**: 2026-05-31 13:23 **Completed**: 2026-05-31 13:24 **Duration**: 1 minute **Notes**: * Added compact snake\_case Codex aliases for session, mission, turn, permission mode, hook event, agent, tool, and MCP tool names. * Allowed `SubagentStart` to carry `type: "subagent_spawn"` in the shared hook ingest payload union. * Kept raw transcript, patch, command output, MCP argument bodies, credentials, and broad payload bodies out of promoted protocol fields. **Files Changed**: * `packages/protocol/src/ingest.ts` -

Normalized CLI values through shared protocol vocabulary. * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/tasks.md` - Marked T009 complete. **BQC Fixes**: * Contract alignment: server no longer maintains a divergent CLI allowlist that omits `codex-cli`. *** ### Task T010 -

Materialize full Codex lifecycle through existing managers **Started**: 2026-05-31 13:26 **Completed**: 2026-05-31 13:36 **Duration**: 10 minutes **Notes**: * `SessionStart` with `session_id` and `cli: "codex-cli"` now creates a first-class Codex hero. * `UserPromptSubmit` starts the parent mission through the existing mission manager, and `Stop` completes it. * Existing active mission and tool-use duplicate guards continue to prevent duplicate materialization while events are in flight. * Full fixture replay test verifies hero state, parent mission completion, child mission completion, and event emission. **Files Changed**: * `apps/server/src/lib/eventIngest.ts` - Normalized session and hook aliases needed by lifecycle events. * `apps/server/src/routes/event.ts` - Accepted `codex-cli` and preserved existing manager-based lifecycle routing. * `apps/server/tests/eventIngest.test.ts` - Added full lifecycle materialization test. * `.spec_system/specs/phase10-session03-server-ingest-codex-lifecycle/tasks.md` - Marked T014 complete. **BQC Fixes**: * Duplicate action prevention: mission start and tool use paths continue reusing active mission/tool IDs. * State freshness on re-entry: Stop clears active mission state after completion. *** ### Task T015 -
