 - Prepared a normal no-ff merge of reviewed AI Programming source `65040730ec229436b27e0e1a34ca16599b534996` onto local `main` `b734867`; Git reported no textual conflicts, current project-cover behavior remains present, and the source task record remains only on feature history.
 - Integrated application-side per-Session run/error/queue isolation, an independent hard 10-second startup acknowledgement deadline, typed pre-send runtime/Agent pending responses, generation/fingerprint Agent readiness, bounded manager/project FIFO acceptance and timeout lease revocation. Ordinary message/command/summarize/background sync does not automatically restart, reload or dispose the shared runtime.
 - Promoted the source architecture candidate into current state, data flow and module ownership, and recorded verified evidence plus the still-pending real bundled OpenCode/provider two-Session smoke. No claim of upstream simultaneous model execution was added.
+- Created normal no-ff merge commit `ce897f14cc93370e42b2882e4be236040f49c8a6` with current local main `b7348670a6503047e1703ca61cd6e2a9913f6182` as first parent and reviewed source `65040730ec229436b27e0e1a34ca16599b534996` as second parent.
 
 - Prepared a normal no-ff merge of project-cover source `145a6ce571d646325092d1e722282babea503954` onto local `main` `da376b0bf37cdd0b5eabe7efc9f1141ae5645411` with no textual conflicts; the source feature task record remains only on the source branch.
 - Reconciled the obsolete coverless-first-create rule into required first-cover atomic submission while retaining existing-project version-only behavior and the unfulfilled conditional metadata-editing commitment.

 - Multi-Session staged merged-tree `pnpm run build:vite` passed for Renderer, Electron Main and Preload; only existing mixed-import and chunk-size warnings remain.
 - Focused Electron E2E `tests/e2e/opencode-multichat-runtime.spec.ts` passed 1/1 through the built Main/Renderer Host stub, preserving Session A busy state while Session B terminates independently without retry.
 - Independent final staged-merge Sol review returned Standards `PASS`, Spec `PASS`, overall `PASS`, with no blocking findings. It independently reran 13 files / 490 tests, confirmed exact `HEAD=b734867` / `MERGE_HEAD=6504073` topology, source-task-record exclusion, no unmerged or unstaged changes, preserved project-cover behavior, canonical document consistency, and the explicit non-claim for real provider concurrency.
+- Post-commit topology confirms `ce897f1` has exact parents `b734867` and `6504073`, the source is a `main` ancestor, and source task record `20260817-multichat-runtime-fix-f3a91c.md` is absent from the integrated tree.
 
 - Project-cover source verification: 3 focused Vitest files / 76 tests, typecheck, scoped ESLint, Vite production build, focused Electron E2E 1/1, and cross-repository Sol review all passed.
 - Project-cover merged tree: 3 focused Vitest files / 76 tests, `tsc --noEmit`, scoped ESLint, Renderer/Main/Preload Vite production build, and focused Electron E2E 1/1 all passed; build emitted only the existing dynamic-import and chunk-size warnings.
