From 8019e0e18aba3d00b25e68f5d6a3cd113c01b6f2 Mon Sep 17 00:00:00 2001 From: Muhammad Ahmed Cheema Date: Wed, 15 Apr 2026 08:53:56 -0700 Subject: [PATCH 1/4] feat(chat): PR1 backend foundations for web chat channel Server-side infrastructure for the Phantom chat channel. No client code yet - this PR stands up the backend that PR2's React client will connect to. New modules in src/chat/: - 24-event SSE wire format (types, sdk-to-wire translator) - Session, message, event log, and attachment SQLite stores - Per-session writer with stream bus fan-out and abort support - HTTP route handlers for /chat/* endpoints - Auto-rename via judgeQuery Haiku (Cardinal Rule) - Periodic sweep for expired sessions and orphan data Integration points: - AgentRuntime.runForChat using AsyncIterable with includePartialMessages, agentProgressSummaries, promptSuggestions - WebChatChannel registered for health/discovery (bypasses router) - Cookie path widened from /ui to / for cross-path auth - 12 SQLite migrations (indices 28-39) for chat tables 68 new tests, 1471 total, zero regressions. --- bun.lock | 97 ++++++ package.json | 1 +
