# Task: Design one ongoing conversation per user and cloud agent ## Identity - Task ID: 20260928-agent-single-chat-27da516b - Mode: Feature - Branch: codex/20260928-agent-single-chat-27da516b-agent-single-chat - Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260928-agent-single-chat-27da516b - Base commit: b26e25c9ed26bf30f4d0bc03869c223f0fe34386 - Owner: codex - Status: Ready for Integration ## Scope - User approved the proposed account + delivered-agent single ongoing chat and implementation. - Client store, per-turn scope/version, Host API, paged UI, legacy history, drafts, read receipts and focused regressions. - Coordination with the existing proactive-observer task was explicitly authorized. This task does not own its uncommitted implementation or its Reviewer. - No main merge, push, deployment, real paid model call, new subagent or worktree cleanup. ## Intent And Constraints - Concurrent Task Gate and Planning Gate Passed on initial design and implementation resume; official start/status confirmed this task's feature ownership. - Refreshed 128 peer records, read only their task records; consultation-scope client task is read-only diagnosis. Observer code remains in a separately owned worktree. - Stable delivered config ID, account isolation, student payer and three readonly tools remain. Pi/project files stay project-owned. - Every accepted question freezes project, Pi source and released version. Switching UI never changes an accepted read scope. - Existing main foreign documents and unrelated worktrees remained untouched. Only this task record/proposal are changed in project memory; canonical promotion remains integration work. ## Outcome - Main stores one account-agent chat under userData/agent-conversations//. A small message index and separate atomic turn files avoid rewriting every historical answer. - First question ensures the chat; repeated request IDs are idempotent, including older pages. One active manual question per account-agent. Snapshot progress/completion updates by request ID. - Latest 50 turns initially; older history pages remain available. SSE sends the current turn and metadata. Renderer merges delayed pages without overwriting newer streamed replies, preserves reading position while switching agents, and keeps account-agent text drafts. - Removed student new-topic plus and normal topic dropdown for delivered agents. Current project/source are shown. Cross-project/Pi references block sending until removed or the source is reopened; old reply actions cannot target another Pi session. - Contacts retain distinct unread state; read position is persisted in Main. Last selected disabled agent can reopen readonly history. Loaded-page/scroll cache is window-local; durable messages and read receipts survive restart. - Next question uses the current released definition. Same project/Pi/version reuses its internal thread; changing any starts an internal segment carrying bounded public history. Old imported cloud questions retain original cloudRequestId for cancellation. - Readonly conversation tool can retrieve older completed chat messages by ID through the frozen index without loading all bodies each question; prior-project message text does not grant prior-project file access. - Legacy topics are imported only on proven account/config identity, deduplicated by project/topic/request origin, and original files are retained. Body-before-index interruption recovers without duplicate import, including retry in the same process. Missing project directories can be retried later. Historical project and source topics, including unassigned/friend records, remain readonly via the old-records endpoint. - Discussion state is per project inside the chat; imported old cards retain their turn snapshots and newest project card. Legacy originals remain separately viewable. - README updated for the implemented client behavior. Accepted teacher ADR/domain/architecture changes are proposed, not promoted. ## Verification - Relevant unit suite: 12 files, 365 tests passed. Includes Store/Service/actual HTTP + SSE/paging/legacy source archive/account isolation/concurrent duplicate acceptance/versions/Pi switching/frozen file roots/older message tool reads/import failure recovery/read receipts/UI delayed pages/old-record readonly/disabled history/independent agent drafts. - pnpm run typecheck: passed. - Focused ESLint over every changed TS/TSX file and new files: passed. - pnpm run build:vite: passed; existing chunk-size/dynamic-import/Browserslist warnings retained. - Real Electron test with deterministic Host fixtures: project consultations preserve student drafts and switch between work and chat without submitting advice, 1/1 passed. Screenshot manually inspected: topbar agents, one chat, no new-topic plus/select, project label, separate drafts, work tab preserved. Not a live cloud/model acceptance claim. - Expanded Main tsc: 66 diagnostics. Temporarily replayed original committed source inside this owned worktree under try/finally restoration; baseline also has the same 66 diagnostics (line positions normalized). No new diagnostics, but global Main typecheck is not clean. - Reproduced existing coding-teacher.test tool activity ID failure on original base: test expected parent run ID, existing implementation uses stable context/request ID. Corrected that assertion to the existing contract; the full related suite then passed. - No dependency lock/package change. Build output, local reports, runtimes and temporary checks are ignored and not committed. ## Coordination And Integration Dependency - Authorized messages sent to existing thread 01a0dc9a-9b4e-7fa3-bb19-aea80abaaac4, task 20260928-agent-observer-design-9c41a872. - That task confirmed its Main suggestion contract in its own record: stable suggestion ID survives replacements; state.json is durably saved before advice delivery. Use projectId + suggestion.id for idempotent delivery; do not call sendConversation to invent a student message. - Actual manual APIs: GET /api/coding/agent-conversations/:agentId?before=...; POST /messages; /seen; /discussion; /save; /requests/:id/cancel; GET /events. service.conversation(agentId,before?) and service.sendConversation(agentId,input) own the unique chat. - Observer review was still in progress at this handoff; no observer code is in this branch. The combined integration MUST replace its discussObservation project-topic creation with inserting/opening this chat, plus delivery replay/read receipts. Its independent observation thread and Main project scheduler remain separate. Do not claim automatic advice has already been wired or combine branches without this adaptation and joint tests. - Observer coordinator source inspection confirmed Yuxi scope binds both project and Pi source, and native YuxiSummarizationMiddleware exists. This justified Pi-aware segment rotation; neither cloud deployment nor compression quality was independently exercised here. ## Follow-ups - User-requested main merge is not yet authorized for this implementation. - During integration reconcile observer suggestions as above, and promote the approved account-agent/per-turn semantics; retain unrelated docs. - Validate configured Yuxi deployment against current client; no real cloud/paid-model run occurred. Cross-device history synchronization is outside this increment. - Retained worktree belongs to this completed feature; no cleanup requested. ## Promotion Candidates - Targets: ADR-2026-09-22-coding-teacher.md, system-overview.md, data-flow.md, business-rules.md and current state. - Proposal: replace visible project/version topic identity with account-agent chat; bind project/Pi/version to individual execution turns; account-agent drafts/read receipts, paged files/index, retained source archives. - Evidence: approved user request, implementation, 365 related tests, Electron UI and cloud request contract tests. - Future impact: history lifecycle, cloud scope rotation/summary, old-context actions, observation delivery. - Semantic conflicts: accepted project-topic/version policy is intentionally revised by user approval; observer project-topic creation must be adapted at joint integration. - Human confirmation: single-chat direction and implementation approved. Main merge/deployment require their own corresponding user request.
