Task: Merge coding conversation management into main

Identity

Fast-forward completed source fd0293fe3d into local main and promote the accepted Code conversation title/archive ownership and behavior.

User requested main integration and explicitly confirmed releasing completed owner 20260920-merge-account-ui-38b91cd6 and adopting the three original untracked task documents unchanged. Official release/start/status succeeded; this task exclusively owns main and the integration lock at the recorded base.
Concurrent Task Gate and Planning Gate Passed. Read entry, active task, memory index, positioning/current-state, Pi ADR-006, architecture/domain/success criteria, relevant evidence/reflection/commitment context and all 145 peer scope/intent/promotion sections. Historical placeholders remain unknown/read-only without a concrete conflicting dependency. The current skill takes precedence over legacy local shared-document restrictions and reflection advice.
User explicitly replaced the earlier model-generated-title proposal with first-user-message titles; this implementation and promotion honor that amendment. Preserve Main ownership, running work and manual/historical titles. Source task records stay read-only. No subagents, unrelated product changes, remote push, packaging or deployment.

Fast-forwarded local main from d612265 to fd0293f without conflicts. The merge includes archive/restore, shared rename UI and one-shot first-user-message titles without a model call.
Promoted the accepted metadata flow, module ownership and domain behavior in data-flow, module-map and business-rules; recorded the source commit under current-state Integrated Through. The source task record was imported unchanged.
The original untracked documents 20260901-package-122-c5e8.md, 20260901-package-123-d7f3.md and 20260902-client-hang-diagnosis-a47c9e2b.md remain outside the integration commit.

Source ancestry confirmed a direct fast-forward; the source worktree was clean at fd0293f. After merge, both the complete product tree and source task record match fd0293f exactly.
Reuse exact-source verification because the fast-forward introduces no product edits: 114 focused tests plus one pressure test, one Electron rename/archive/restore fixture, frontend typecheck, lint (0 errors, 8 existing warnings), and Vite Renderer/Main/preload/utility build passed. Real pinned Pi 0.84.2 history hydration was covered locally; no live Provider turn is claimed.
Explicit Main TypeScript checking retains baseline failures: source comparison found 89 baseline and 88 current diagnostics, with no added diagnostics. This integration does not broaden scope to those pre-existing errors.
git diff --check and the task-aware documentation drift check passed. The latter confirms imported source provenance and that all three adopted foreign documents are unchanged. Source registry/readiness, clean status, branch and latest HEAD match the committed source record.

Source task 20260920-coding-session-controls-10fee632 is retained awaiting cleanup confirmation at D:\Datas\OthersProjects.codex-worktrees\makelore\20260920-coding-session-controls-10fee632, branch codex/20260920-coding-session-controls-10fee632-coding-session-controls. Its latest result is integrated; removing the checkout also removes ignored dependencies/build output while preserving branch and commits. Main is not a cleanup candidate.
An updated client build/install is needed to expose the feature in an installed app; this task only integrates source locally.

Accepted and promoted: Main metadata owns stable manual/historical and first-user-message automatic titles; archive preserves running work; list metadata invalidation is separate from sequenced runtime patches. The user's explicit amendment supplies the product decision; Pi runtime and Provider ownership remain unchanged.
