• 🟡 (23:11) Fresh standalone binary build completed successfully at packages/opencode/dist/server/opencode-server.
• 🟡 (23:12) Final working-tree status showed adaptive rail edits in packages/app/src/components/titlebar-tab-nav.css, packages/app/src/components/titlebar-tab-nav.tsx, packages/app/src/components/titlebar-tab-rail-state.ts, packages/app/src/components/titlebar-tab-rail.tsx, and packages/app/src/components/titlebar-tab-strip.tsx; diff summary: 7 files changed, 27 insertions, 5 deletions.
• 🟡 (23:12) Unrelated existing modifications remained in .lore.md (3 additions) and AGENTS.md (6 additions), and untracked profiler captures perf.data and perf.data.old remained untouched.
• 🟡 (23:12) All high-priority tasks marked completed: “Inspect one-row expanded rail option,” “Rebase cumulative branch onto latest upstream,” “Implement adaptive expanded tab density,” and “Typecheck and build fresh binary.”
• 🟡 (23:12) Assistant reported byk/cumulative was rebased onto latest origin/dev.
• 🟡 (23:12) Validation results: packages/app bun typecheck passed; standalone server bun run build:server passed; packages/opencode typecheck remained blocked by existing test/provider/transform.test.ts:3886 because "none" is not a valid effort value.
• 🟡 (23:13) User asked whether there was a verified build before restarting the OpenCode service, expressing concern that restarting could reveal it is broken. [requested-verification]
• 🟡 (23:13) Assistant stated the binary had built but had not yet received an isolated smoke test, and planned to test the fresh artifact without touching the running service.
• 🟡 (23:13) Initial invocation of packages/opencode/script/smoke-server.mjs failed before starting a server because no executable argument was supplied; the script requires smoke-server.mjs <executable>, under Bun v1.3.14 (Linux x64).
• 🟡 (23:13) Reran the smoke test with dist/server/opencode-server; isolated server smoke checks passed at http://127.0.0.1:14096/.
• 🟡 (23:13) Assistant reported the fresh packages/opencode/dist/server/opencode-server started, served smoke checks, and shut down cleanly without touching the running OpenCode service.
