Thread management is an afterthought: a broken OS-native prompt, identically-titled rows, and durable backend machinery (checkpoints, leases, projects) with no visible counterpart. The data model says "durable workspace threads"; the UI says "a dropdown and a plus button." + +**Deterministic scan**: detector exit 0, zero findings — the defects here are behavioral/architectural, not mechanical. + +## Root cause of "new thread keeps the same chat context" (both agents agree) + +1. **The New thread button is broken in the desktop app — silently.** `createThread()` calls `window.prompt()`, which **Electron does not support** — it throws. The call is fire-and-forget with no catch, so it dies as an unhandled rejection before `thread.create` is ever sent. Click "New thread" → nothing happens, old chat stays. No error anywhere. +2. **Model context comes from local React state, not the thread.** `messages` is one `useState([])`; every send builds the LLM payload from that local array, never from `threadManager.readConversation()`. Incoming `conversation.response` events are appended **without checking threadId** — a reply from thread A can stream into thread B's view and ride along as context. Cross-thread bleed is structural. +3. Switching threads *does* replace the transcript (`runCommand("thread.switch")` sets messages from the backend conversation) — but since creation is broken, users rarely get that far, and the payload-context bleed remains regardless. + +## Overall Impression + +The chat surface is a genuinely distinctive product idea executed with care. Thread management is the same app's blind spot: the backend is *durable* (registry.json, JSONL conversations, checkpoints, archive/cancel/rename all implemented) and the UI exposes almost none of it, with the one entry point it does expose silently broken. The single biggest opportunity: make the thread model the source of truth for chat context, and surface the management verbs the backend already has. + +## What's Working + +1. **Authored trust architecture** — verbatim model output visually separated from host actions/evidence/telemetry; receipts and raw-output references are distinctive and consistent. +2. **Progressive disclosure discipline** — reasoning, telemetry, envelopes collapse behind honest summaries with token counts. +3. **Thoughtful error text where it exists** — IPC-wrapper stripping and stale-session recovery copy show real care; it just never reached the thread path. + +## Priority Issues + +1. **[P0] New thread is broken and silent** — `window.prompt` throws in Electron; no error handling. Fix: in-app new-thread dialog (recent projects + `dialog.showOpenDialog` directory picker + optional title), try/catch, surface via the error banner. +2. **[P0] Conversation state is local, not thread-owned (context bleed)** — LLM payload built from local state; `conversation.response` events appended without threadId filter. Fix: make `readConversation(activeThreadId)` the source of truth for payloads; filter stream events by threadId; clear messages on `thread.switched`. +3. **[P1] No thread management surface** — backend has rename/archive/cancel/resume; UI has none. Fix: per-row actions in the thread popover (rename inline, archive with confirm+undo toast, cancel for running threads), collapsed "Archived (n)" section with restore. +4. **[P1] Thread identity is unreadable** — identical titles, no timestamps, no preview. Fix: auto-title from first user message (~60 chars), show relative `updatedAt` + last-message snippet per row. +5. **[P2] New-thread flow demands a raw directory path** — intimidating, error-prone; backend already models Projects.

Hit-testing confirms interception; Escape from the opener fails. Keep the composer outside compact inspection geometry, stop auto-opening on mode changes, and manage focus/Escape/outside-click. Suggested commands: harden/adapt. Sources: main.jsx inspector and styles.css compact rail; assessment A interaction-checks.json and B confirmed-interactions.json. +2. **P1 — Conversation space is starved.** At 520x480 the transcript is 134px versus a 209px composer; at the 760x620 desktop transcript is 100px. A text-only 200% stress test reduces it to 40px. Consolidate chrome, grow the draft input as needed, disclose secondary context, guarantee a reading floor and allow overflow to remain reachable. Suggested command: layout/adapt. +3. **P1 — First run lacks a clear starting point.** Empty telemetry, lifecycle vocabulary and Continue task dominate before real work. Add an idle task-first home with Chat, model configuration and genuine recent work; retain rich active/blocked views. Suggested command: onboard/distill. +4. **P1 — Verified text contrast failures.** Thread ready label is 1.72:1 paper and 1.39:1 understory. Timestamp 1.99:1, objective supporting copy 3.48:1, active lifecycle label 3.89:1. All require 4.5:1. Scope paper metadata/status tokens correctly and verify computed colors in both themes. Suggested command: colorize. +5. **P2 — Navigation and Settings lack task hierarchy.** Eleven dock choices compete; catalog repeats in overview and palette. Settings is a 374px viewport over 1613px content with model setup interleaved with scheduler/training. Prioritize frequent/open windows, group the full library, stabilize numeric shortcuts, and split Settings into Models/accounts, Workspace, Context/memory and Advanced/runtime. Suggested commands: shape/distill. +6. **P2 — Theme and information integrity gaps.** Large paper surfaces bypass understory tokens, essential state labels remain 9px, and Dream shows hard-coded loss polylines with no visible illustration disclosure. Use semantic surfaces, readable functional metadata, and honest empty training observations instead of decorative evidence. Suggested commands: colorize/typeset/clarify. + +## Cognitive load and personas + +Assessment A marked five of eight cognitive checks failed: single focus, chunking, hierarchy, one-thing-at-a-time, and minimal choices. Grouping, working memory support and general progressive disclosure were strengths. Alex/power users hit an obstructed Build action and cramped transcript; Jordan/new users decode an idle cockpit and scattered setup; Sam/keyboard-low-vision users face concealed focus and pale small status text. + +## Detector evidence and limits + +CLI markup scan returned zero findings. Runtime detector produced 774 raw occurrences across Center/Chat/Dream: repeated elements, intentional occlusion of inactive windows, pinned brand treatments and generic font thresholds explain many. They are not 774 independent bugs. The confirmed technical audit consolidates six issues (0 P0, 2 P1, 4 P2). Runtime injection and overlay DOM succeeded, but user-visible browser presentation was not established; no live user overlay is claimed. Helper was stopped and existing dev server preserved. No inference, training or real conversation changes were used in the assessment. + +## Minor observations + +Browser preview footer incorrectly claims Electron Runtime; project directory is hidden in Build; role=badge is invalid; stacked optional browser preview does not scroll a newly focused window into view. Fix these within the broad pass. + +## Direction resolved by user authorization + +The user has already requested broad fixes, not an assessment-only deliverable. Proceed with task-first home, a leaner nonblocking Chat layout, frequent/current-work navigation, grouped Settings and honest readable system states. Do not reopen the already confirmed scope or visual identity.
