QA Evidence: fix 5786

What Was Tested

• Failing-first regression: bun test packages/omo-opencode/src/cli/doctor/checks/tui-plugin-config.test.ts -t "passes when tui.json contains the package entry and a tuple plugin entry".
• Final doctor suite: bun test packages/omo-opencode/src/cli/doctor.
• Typecheck: bun run typecheck.
• No-excuse TypeScript rule check: bun /Users/yeongyu/.agents/skills/omo-programming/scripts/typescript/check-no-excuse-rules.ts packages/omo-opencode/src/cli/doctor/checks/tui-plugin-config.ts packages/omo-opencode/src/cli/doctor/checks/tui-plugin-config.test.ts.
• Real-surface doctor proof: isolated XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME, and OPENCODE_CONFIG_DIR; wrote opencode.json with ["oh-my-openagent"] and tui.json with ["oh-my-openagent", ["./badge.tsx", {"label":"custom"}]]; ran bun packages/omo-opencode/src/cli/index.ts doctor --platform opencode --json.

What Was Observed

• RED proof: red-tuple-regression.log shows the new regression failed on current code with Expected: "pass" and Received: "warn".
• GREEN proof: green-tuple-regression.log shows the same named regression passed after the guard fix.
• Final doctor suite: doctor-suite-final-2.log shows 159 pass, 0 fail.
• Final typecheck: typecheck-final-2.log exits 0 across repo package typechecks.
• No-excuse rules: no-excuse-rules-final.log shows No violations in 2 file(s).
• Isolated doctor proof: isolated-doctor-final/tui-plugin-result.json shows the TUI Plugin check status is pass, message is Server and TUI plugin entries are both registered, and issues is empty.
• isolated-doctor-final/assertion.txt shows PASS isolated doctor tuple proof; isolated-doctor-final/missing-warning-grep.txt is empty, proving the false TUI plugin entry missing warning did not appear.

Why It Is Enough

• The regression exactly models issue #5786: a valid OMO package entry plus a tuple-style TUI plugin entry.
• The red run proves the defect existed on this HEAD before production code changed.
• The green run, full doctor suite, and typecheck prove the minimal guard fix preserves existing doctor behavior.
• The isolated CLI doctor run exercises the user-facing doctor surface against real JSON config files, not only the unit helper.

What Was Omitted

• No full design split was made for tui-plugin-config.ts, even though it is a pre-existing oversized file, because issue #5786 was explicitly scoped as a pure mechanical bug fix with zero design decisions.
• No GitHub issue comment was posted.
• No package version was changed.
• No secrets, auth headers, or private environment dumps were captured.

Setup Notes

• Initial bash script/agent/setup.sh failed because bun was not on PATH in the shell.
• Rerun with PATH=/Users/yeongyu/.bun/bin:$PATH installed dependencies but hit local-file submodule protocol restrictions.
• Rerun with environment-only GIT_ALLOW_PROTOCOL=file:https:ssh:git initialized the local submodule fixtures, then failed during strict Codex plugin build materialization for the frontend designpowers reference. The requested OpenCode doctor tests and real-surface proof above completed independently.
