Task: Merge conversation abort reconciliation into main

Identity

Merge exact verified candidate 599d184 into local main after the human-authorized closure of packaging task 20260901-package-121-7a3c.
Preserve the candidate's product implementation and canonical current-state reconciliation while retaining the packaging task's committed record.
Verify the merged product tree, exact ancestry, focused behavior, documentation boundaries, and clean task state. Do not package, install, publish, deploy, or push.

Preserve ADR-006: Pi 0.84.2 remains the only production Coding runtime; Electron Main remains the Host API authority; accepted or uncertain work is never replayed; recovery remains target-only Snapshot/Patch convergence.
The existing 1.2.1 installer was built from pre-fix source and must not be overwritten or represented as containing this change.
The user explicitly authorized takeover of the known packaging task. That task was closed in commit ebc46c6 and released cleanly before this Integration Gate began.
Concurrent and Planning Gates passed on exact base ebc46c6: the active record, candidate/source outcomes, accepted decision, canonical memory, and all 210 peer records were read. No semantic conflict or competing integration owner exists.

Verify the candidate ancestry and conflict-free merge tree against current main.
Merge candidate 599d184 with an explicit integration commit, preserving both the packaging closure and verified abort-reconciliation history.
Run the focused abort UI regression plus typecheck and production build, then verify exact candidate product-tree parity and repository documentation gates.
Record the actual merge and verification outcome, commit the integration ledger, complete the task, and release main from a clean state.

Verified a conflict-free merge tree 06a1e65143c10c67c4eda1b9ee277e13210bf01f between current main and candidate 599d184; their common base was 143aaec, with one main-only and two candidate-only commits.
Merged the exact candidate into local main as 85900717906713d8343c2087eade904aead8f111, preserving both packaging closure ebc46c6 and the feature/integration history d2ef37b / 599d184.
Omitted the two source-owned task-record copies from the final main file tree after the task-aware drift gate correctly rejected them. Their unchanged records remain reachable in source/candidate commits and merge history; product code, tests, and canonical current state remain integrated.
Canonical current state now records the actual local-main merge rather than a prepared promotion. No ADR, architecture, domain, README, dependency, package, installed data, deployment, publication, or remote branch was changed.

Post-merge product tree exactly matched verified candidate 599d184; no non-doc path differs, and the candidate is an ancestor of main.
Focused post-merge regression passed: 5 files / 35 tests.
pnpm run typecheck passed.
pnpm run lint:check passed with 0 errors and the same 5 existing warnings in src/pages/Home/index.tsx and src/pages/Makelore/index.tsx.
pnpm run build:vite passed for Renderer, Electron Main, Preload, and release utility bundles with existing build warnings only.
Post-merge Electron E2E passed: targeted PI feature UI scenario 1/1, including the missed-terminal-SSE abort reconciliation and both controls unlocking.
Source full-suite evidence remains applicable because the merged product tree is byte-identical to the candidate: 215 files / 1,780 tests with 2 skips, plus the isolated pressure test 1/1.
Task-aware documentation drift, project-document structure, merge ancestry, product-tree parity, whitespace, and clean-status checks are rerun before release.

Increment the application version, build and verify a new Windows installer, install it, and repeat the reported interaction before claiming installed-client acceptance. The existing 1.2.1 installer remains valid historical evidence but does not contain this fix.

Resolved: .project-docs/30-worklog/current-state.md records the exact source, verified candidate, local-main merge, unchanged contracts, and pending release gate. No further canonical promotion is proposed.
