Problem

Tests bumped their own timeout (it(name, fn, 60_000)) or were skipped with no tracking issue. Both hide waits that should be event-driven, and a skip with no owner never comes back.

Fix

• New rule t3code/no-test-timeout-or-unreasoned-skip: flags a numeric or {timeout, retry} argument on it/test/describe/hooks, vi.setConfig({testTimeout}), and .skip/.only/.todo without a leading // quarantine: #issue comment. skipIf/runIf platform gates stay allowed. *.live.test.* provider probes keep their timeouts (they run real agents for minutes behind env gates).
• Removed 58 overrides across 17 files; one suppression on the env-gated recovery benchmark.
• Root vitest config: allowOnly: !CI, explicit retry: 0, full fakeTimers.toFake set.
• AGENTS.md Verifying section lists the concrete rules and names the five lint rules that enforce them.

Part of the anti-flake stack (#22563). Context: main was red in ~600 of ~2,900 runs since September; the genuinely flaky tests all waited on real time, scheduler budgets, or renderer frames. These rules make those tests fail lint instead of CI.

Approvability

Verdict: Approved at c925428

Macroscope's review found this PR approvable — This PR is confined to test-suite guardrails and developer tooling: it removes per-test timeout overrides, adds a focused lint rule, and standardizes Vitest test settings. The changes do not alter production request paths, product defaults, or application APIs.

📝 Walkthrough

The changes add lint and Vitest rules for test timeouts, retries, focused tests, and skips. They remove explicit timeouts from several tests and add GitManager coverage for fork pull request detection.

Changes: Test policy and coverage

Layer / File(s)	Summary
Define and enforce test policies AGENTS.md, oxlint-plugin-t3code/index.ts, oxlint-plugin-t3code/rules/*, vite.config.ts	Test guidance, a new Oxlint rule, plugin registration, and Vitest configuration define timeout and skip constraints. Rule tests cover accepted and rejected patterns.
Remove explicit test timeouts apps/mobile/src/reactCompilerCoverage.test.ts, apps/web/src/reactCompilerCoverage.test.ts, apps/server/integration/transferBudgetV2.integration.test.ts, apps/server/src/htmlRender/HtmlRender.test.ts, apps/server/src/httpResponseErrorGuard.test.ts, packages/provider-opencode/src/server/v2/OpenCode2Server.test.ts	These tests no longer specify the listed explicit timeout values. Their test logic and assertions remain unchanged.

Git pull request status coverage

Layer / File(s)	Summary
Cover fork pull request detection apps/server/src/git/GitManager.test.ts	Tests cover fork pull requests tracked through non-origin remotes, including a fork head named main. The synthetic local branch alias test no longer sets a 20-second timeout.

Merge Risk: 🔵 Low · up to c9254

The new lint rule now covers suite aliases and skip/only options, including in live test files. It can still be bypassed with a named-constant or computed timeout argument. Two CPU-heavy coverage suites now run under a 60 s timeout and may be flaky on slow runners. Both are low-impact issues that can be tracked after merge.

- Line 10: Add "suite" to the TEST_FUNCTIONS recognized roots so suite.skip,
suite.only, and suite.timeout calls receive the same checks as describe, it, and
test.
- Line 117: The options check in the test declaration rule currently recognizes
only TIMEOUT_OPTIONS and must also inspect literal skip, only, and todo
properties. Update the relevant logic around hasOption to apply the quarantine
requirement whenever these options enable their corresponding states, while
preserving the existing timeout and retry checks.

- Line 103: Update the CallExpression handler to remove the early return on
checkTimeouts, so quarantine/skip validation still runs in live test files.
Apply checkTimeouts only to timeout-specific reports, including setConfig
detection, numeric hook timeouts, and TIMEOUT_OPTIONS checks, while preserving
the existing skip handling.
- Around line 63-67: Update the argument detection in the rule’s hook and
test-call handling to catch computed or named positional timeout values, not
only numeric Literal nodes: report the second argument when a hook’s first
argument is the callback, and report any third argument when a test’s second
argument is the callback. Preserve the existing object-option checks for timeout
and retry, and adjust isNumericLiteral or its callers as needed to support these
cases.
