Defines the shared types for the messaging protocol v3 redesign: - Message (UserMessage | AssistantMessage) with usage stats, cost, tokens - Part discriminated union (text, reasoning, tool, file, step-start/finish, subtask, agent, snapshot, patch, compaction, retry) - ToolState machine: pending → running → blocked → completed/error - Block types for permissions and questions on tool parts - ResolvedBlock variants preserving decisions after user responds - PermissionRule, Todo, SessionInfo types - ProtocolEnvelope with v:3 version marker Exported as `v3` namespace from happy-wire to avoid collision with legacy UserMessage/UserMessageSchema exports. 21 tests covering all schemas, discriminated unions, and the full tool lifecycle including blocked states with permission and question blocks.

New mapper that converts Claude SDK output into the v3 canonical format: - Builds MessageWithParts objects (not SessionEnvelope streams) - Accumulates parts within a turn: step-start, reasoning, text, tool, step-finish - Tool state machine: pending → running → completed/error - Token tracking accumulated across assistant messages in a turn - Handles system messages (session ID update) and summary messages (skip) - Tool results from user messages complete/error the corresponding tool part 10 tests covering: text turns, reasoning, tool calls, tool completion, tool errors, multi-step turns, token tracking, part ordering. This mapper runs alongside the existing sessionProtocolMapper — it does not replace it yet. The integration point (sendV3Message on apiSession) comes in the next commit. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Integrates the v3 Claude mapper into the message sending pipeline:
- sendClaudeSessionMessage now dual-writes: v1 SessionEnvelopes AND v3
Message+Parts, gated behind HAPPY_V3_PROTOCOL=1 env var
- closeClaudeSessionTurn also flushes v3 in-flight assistant messages
- sendV3ProtocolMessage wraps canonical {info,parts} with {v:3} marker
so the app can distinguish from legacy payloads
The v3 path runs alongside the existing path — no behavioral change
unless HAPPY_V3_PROTOCOL is set. When enabled, both formats are sent,
allowing the app to be migrated incrementally.

Converts Codex MCP events into canonical v3 format: - task_started/task_complete → turn lifecycle (step-start/finish) - agent_message → text parts - agent_reasoning → reasoning parts - exec_command_begin/end → tool parts (running → completed/error) - patch_apply_begin/end → tool parts (running → completed) - exec_approval_request → tool blocked (permission) with command patterns - apply_patch_approval → tool blocked (permission) with file patterns Key difference from Claude mapper: Codex approval events map directly to the `blocked` tool state, producing PermissionBlock with the command or file patterns. This is the first mapper that actually produces blocked tool parts — the Claude mapper will follow this pattern once its permission handler is wired in. 9 tests covering all event types, tool lifecycle, blocked states, and step ordering.

Adds methods to the v3 Claude mapper for tool state transitions: - blockToolForPermission(state, callID, permission, patterns, metadata) → tool goes running → blocked with PermissionBlock - unblockToolApproved(state, callID, decision) → tool goes blocked → running, resolvedBlock preserved for completion - unblockToolRejected(state, callID, reason) → tool goes blocked → error with ResolvedPermissionBlock - blockToolForQuestion(state, callID, questions) → tool goes running → blocked with QuestionBlock - unblockToolWithAnswers(state, callID, answers) → tool goes blocked → running, resolvedBlock preserved for completion When a tool completes after being unblocked, the resolved block (with decision/answers and decidedAt timestamp) is preserved on the completed or error state. This is the audit trail — permission/question history survives encrypt → server → decrypt → refetch. 13 tests total: 10 original + 3 new (permission approve, permission reject, question with answers).

Converts v3 ProtocolEnvelope (Message + Parts) into the app's flat
Message[] format at ingestion time:
- isV3Envelope() detects {v:3} payloads vs legacy
- convertV3ToAppMessages() maps parts to app message kinds:
- text → AgentTextMessage
- reasoning → AgentTextMessage (isThinking: true)
- tool → ToolCallMessage with full state mapping
- step-start/finish, snapshot, patch → skipped (structural)
- Tool state mapping:
- blocked → running + permission.status: 'pending'
- completed with block → permission.status: 'approved' + decision
- error with block → permission.status: 'denied'
- ResolvedBlock.decision maps to ToolCall.permission.decision
This converter runs at decrypt time. v3 messages bypass the reducer
entirely — the canonical format already has all the structure. Legacy
messages continue through the existing normalizeRawMessage → reducer
pipeline.
10 tests covering all message types, tool states, permission states,
and structural part skipping.

End-to-end test verifying v3 payloads (as produced by CLI mappers) convert correctly to app Message format: - step 1: text response round trip - step 2: reasoning → isThinking: true - step 3: permission reject → tool error + denied - step 4: permission once → completed + approved - step 5: permission always → approved_for_session - step 6: auto-approved → no block field - step 12: question blocked → pending, then answered - step 10: cancelled tool stays running - legacy detection: all 6 legacy formats rejected, v3 accepted - persistence: permission decisions survive JSON round trip 10 tests, all passing.

…34 steps happy-sync-major-refactor.md specifies the target architecture after the v3 migration: SyncNode as single sync primitive, one type system (MessageWithParts everywhere), session-scoped tokens, decision/answer messages for permission resolution, and 4-level testing strategy. exercise-flow.md expanded from 24 → 34 steps covering: - multi-permission (steps 25-26) - subagent permissions (step 27) - stop with pending state (steps 28-30) - background tasks (steps 31-33) - wrap-up summary (step 34) Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>

…erhaul Work done by automated claude/codex loop (loop.sh) over ~9 hours: - Renamed happy-wire → happy-sync, updated all imports across monorepo - Built SyncNode class (transport, encryption, state, outbox, pagination) - Deleted happy-agent package (absorbed into daemon + SyncNode) - Deleted happy-wire package - Removed legacy message processing from app (reducer, v3Converter, dual-write) - Wired CLI sessions to SyncNode via SyncBridge - Server auth + socket hardening for SyncNode tokens - Level 0 unit tests passing (protocol, mappers, SyncNode state) - Level 1 integration tests passing (20/20, auto-boots server) NOT working (despite agents claiming 85% done): - Level 2 e2e tests NEVER RAN — silently skipped due to env var checks and structurally broken (no CLI process spawned to respond to messages) - Daemon → CLI spawn wiring on session creation not implemented - E2e test infrastructure needs complete rework Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>
The previous loop ran 29 iterations with a vague prompt ("read the spec
and do what it says") producing busywork while e2e tests never ran.
New approach:
- loop-state.md: persistent state between iterations, tracks current task
- loop-prompt.md: focused instructions with explicit anti-patterns
- Tests must boot real server + real daemon (not spawn CLIs directly)
- CLIs are already authenticated — no env var skip conditions
- Skipped tests are failures, not successes

- Move .dev/{loop-prompt,loop-state}.md + loop.sh into loop/{prompt,state,run}.sh
- Add loop/learnings.md with hard-won knowledge from 37 iterations
- Wire learnings into prompt workflow (read before working, append when discovering)
- Add "git diff --stat HEAD" step so agents check previous iteration's work
- Gitignore loop/logs/ — iteration logs are ephemeral
- Remove old .dev/v3-loop-logs/ from tracking

- Control messages as flat top-level types (AbortRequest, RuntimeConfigChange,
PermissionRequest/Response, SessionEnd)
- Migrate to official @anthropic-ai/claude-agent-sdk (setModel, interrupt)
- Consolidate agent state + metadata into session state cache
- Smart Zustand (SyncNode as single source, fine-grained selectors)
- Strict typing end-to-end, no intermediate types
- Added data flow report: docs/notes/happy-sync-major-refactor-report-for-human.md
- Added loop introspection guide: loop/loop-introspection.md
- Updated loop prompt: commit regularly, clean up orphan processes
