Phase 03 Plan 01: Hook Event Processing Summary

HookEvent parsing, event-to-state mapping (Notification/Stop/PostToolUse/PreToolUse), UpdateFromHook avec auto-create, et HTTP handler POST /hook avec validation

Performance

• Duration: 3 min
• Started: 2026-03-23T18:38:37Z
• Completed: 2026-03-23T18:41:45Z
• Tasks: 2
• Files modified: 4

Accomplishments

• HookEvent struct couvre tous les champs du payload Claude Code hooks
• processHookEvent mappe les 4 types d'events (Notification, Stop, PostToolUse, PreToolUse) vers State+WaitType
• UpdateFromHook gere les sessions inconnues et les transitions WaitingSince
• handleHook HTTP handler valide method, body size (64KB), et JSON
• 16 tests couvrent tous les cas

Task Commits

1. Task 1: HookEvent struct, processHookEvent mapping, UpdateFromHook, WaitType - e1b176c (feat)
2. Task 2: HTTP handler POST /hook avec validation et protection - 5bec943 (feat)

Files Created/Modified

• hook.go - HookEvent struct, handleHook HTTP handler, processHookEvent, UpdateFromHook
• hook_test.go - 16 tests (12 mapping + 4 HTTP handler)
• protocol.go - SessionInfo enrichi avec WaitType
• protocol_test.go - Test serialisation JSON de WaitType

Decisions Made

• WaitType omitempty : le champ vide est omis du JSON pour ne pas casser les clients existants qui ignorent ce champ
• UpdateFromHook est une methode separee de Update car les hooks ne connaissent pas PID, GitBranch, Preview, Workspace, Label

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• hook.go fournit toute la logique de traitement. Le plan 03-02 peut integrer le HTTP server dans le Daemon (startHookServer, hookPort, poll slowdown).
• handleHook est pret a etre monte sur un http.ServeMux.
