Distillation

Date: Sep 9, 2026

• 🟡 (17:55) Task status: “Inspect one-row expanded rail option” and “Rebase cumulative branch onto latest upstream” were in progress at high priority; “Implement adaptive expanded tab density” and “Typecheck and build fresh binary” were pending at high priority.
• 🟡 (17:55) Tool reported no jj repository in the workspace (There is no jj repo in "."), while identifying it as a Git repository and suggesting jj git init.
• 🟡 (17:55) Assistant decided the workspace was Git-only and would use Git for the rebase; planned to fetch origin/dev, identify commits to replay, and rebase the cumulative branch.
• 🔴 (17:57) User directive: always allow Ox Alpha in Go.
• 🟡 (17:57) Repository status showed modified files .github/workflows/server-build.yml, .lore.md, AGENTS.md, packages/opencode/src/node-server.ts, plus other elided modifications; commit history included 3278d490ef feat(app): add optional vertical tab rail, 4f29d63747 feat(app): resizable/collapsible vertical tab rail + review-panel toggle, e228647734 fix(app): SSE exponential backoff, reconnecting indicator, and active session refresh, and 7bbfe425f6 always allow ox alpha in go.
• 🟡 (17:57) Assistant reported that rebase was blocked by uncommitted changes outside tab-rail work: .github/workflows/server-build.yml, packages/opencode/script/build-server.mjs, packages/opencode/script/smoke-server.mjs, packages/opencode/src/node-server.ts, .lore.md, AGENTS.md, perf.data, and perf.data.old. Assistant had fetched origin/dev at 9f8db119fc; the cumulative branch had several local commits above it.
• 🔴 [authorized-local-commit] (17:59) User said the pending changes were likely how the project made the server a Node-based server-only process; authorized committing them or absorbing them into an existing commit so they survive rebase, with the constraint that they must not go upstream.
• 🟡 (17:59) Task status added “Preserve local Node-server changes” as in progress at high priority; rebase was changed to pending, while rail inspection remained in progress and adaptive density/typecheck-build remained pending.
• 🟡 (17:59) Local server-build workflow change in .github/workflows/server-build.yml: removed COREPACK_ENABLE_STRICT: "0"; replaced pnpm/action-setup@f40ffcd9367d9f12939873eb1018b921a783ffaa # v4 and pnpm setup version 10.28.0 with ./.github/actions/setup-bun; removed Node pnpm cache and cache-dependency-path: pnpm-lock.yaml; removed pnpm install --filter opencode... --filter @opencode-ai/app... --ignore-scripts --frozen-lockfile; changed Build server from pnpm --filter opencode build:server to bun run --cwd packages/opencode build:server; retained Node 24.16.0, Fossilize cache key fossilize-node-24.16.0-${{ matrix.name }}, and smoke test command.
• 🟡 (17:59) Local change in packages/opencode/script/build-server.mjs: replaced platform-specific pnpm invocation—process.platform === "win32" ? "pnpm.cmd" : "pnpm" with arguments ["run", "build"]—with run("bun", ["run", "build"], appDir).
• 🟡 (17:59) Local change in packages/opencode/script/smoke-server.mjs: RegressionPlugin() now defines dispose() { return new Promise(() => {}) } to verify third-party cleanup cannot prevent shutdown indefinitely.
• 🟡 (17:59) Local change in packages/opencode/script/smoke-server.mjs: replaced server-startup Promise.race timeout with withTimeout(promise, 15_000, () => \Server startup timed out:\n${output}`)`.
• 🟡 (17:59) Local change in packages/opencode/script/smoke-server.mjs: shutdown now awaits an exit event after child.kill("SIGTERM") through withTimeout(exited, 10_000, () => \Server shutdown timed out:\n${output}`); nonzero exit throws Server exited during shutdown with ${signal || `code ${code}`}:\n${output}; timeout/error triggers child.kill("SIGKILL"), awaits exited, and rethrows; temporary homeis removed in afinally` block.
• 🟡 (17:59) Local change in packages/opencode/script/smoke-server.mjs: added withTimeout(promise, duration, message), which uses Promise.race between the promise and a setTimeout rejection with new Error(message()), and clears the timeout in .finally(() => clearTimeout(timeout)).
• 🟡 (17:59) Local change in packages/opencode/src/node-server.ts: shutdown handler stop removes SIGINT and SIGTERM listeners, starts a 5,000 ms timeout that logs Server shutdown timed out; forcing exit. and calls process.exit(), then invokes server.stop(true); successful stop clears the timeout and resolves, while rejection propagates.
• 🟡 (17:59) Working tree listed modified .github/workflows/server-build.yml, .lore.md, AGENTS.md, packages/opencode/script/build-server.mjs, packages/opencode/script/smoke-server.mjs, and packages/opencode/src/node-server.ts; perf.data and perf.data.old were untracked.
• 🟡 (17:59) Assistant characterized the local changes as moving Fossilize server builds to Bun and bounding shutdown, including a smoke test for a plugin whose cleanup never resolves; planned a local-only checkpoint containing the five implementation files plus .lore.md, while leaving profiler captures untracked.
• 🟡 (18:00) Created local commit fd02b7cf7b on byk/cumulative: fix(server): bound Node shutdown, with 5 files changed, 524 insertions(+), 124 deletions(-). Nearby commits shown: 2cee8cb146 fix(app): prevent stale WebUI asset loads and ad2ad08ec4 feat(server): add Fossilize standalone builds.
• 🟡 (18:00) After the local checkpoint, AGENTS.md remained modified and perf.data plus perf.data.old remained untracked.
• 🟡 (18:00) Assistant stated fd02b7cf7b was a local-only checkpoint and intended to discard only the generated AGENTS.md change, leave perf.data* untracked, then rebase the committed stack onto origin/dev without dropping the local server checkpoint.
• 🟡 (18:00) Git rebase began and stopped at step 2 of 20 when applying a08b2521c1 fix(app): optimistic UI updates for session archive and delete; content conflict occurred in packages/app/src/pages/session/timeline/message-timeline.tsx.
• 🟡 (18:00) Assistant assessed the rebase conflict as an upstream-versus-upstream timeline conflict occurring before the rail commits, and planned to preserve both changes, continue replay, and inspect every subsequent conflict.
