Subject: [PATCH 1/4] fix(test): isolate device-login test from the network and
 bound it with a context timeout

TestRunLogin_EmptyToken drove the full rootCmd.Execute path against real
github.com and waited for the server-declared 10-minute expires_in, so it made
real HTTP/2 calls and could hang CI (REQ-CI-009).

Rewrite the test to redirect cloud.DeviceLoginBase to a local httptest pending
server and call runLoginWithDeps directly with mock deps; it now resolves in
~1s with a token/timeout error and never touches the network.

Add an overridable deviceLoginTimeout (60s) to the Device Flow poll loop and
wrap the flow in context.WithTimeout, propagating ctx to the device-code and
access-token requests via http.NewRequestWithContext. A stalled or hostile
authorization endpoint can no longer hold the client for the full server
expires_in (REQ-CI-008). Extract pollForAccessToken to satisfy funlen.

RED: old test captured HTTP/2 readLoop calls to github.com, hung >8s
GREEN: rewritten test PASS in 1.02s; new TestRequestToken_DeviceLoginTimeout
proves ctx cancellation (<1s, context.DeadlineExceeded)

Subject: [PATCH 2/4] ci(gga): install OpenCode CLI before gga run

GGA shells out to the opencode binary, but the workflow never installed it, so
the review step could not function. Add an 'Install OpenCode CLI' step
(curl|bash installer) and put $HOME/.opencode/bin on GITHUB_PATH, plus a
'Verify OpenCode CLI' step. The job's continue-on-error absorbs installer
failures so a flaky external installer cannot block PRs (REQ-CI-011).

Subject: [PATCH 3/4] ci: scope -race to ubuntu-latest and add weekly full-race
 sweep

The per-PR Test job ran go test -race -shuffle=on on all three platforms, so
Windows and macOS absorbed the race detector's ~2x cost on every push. Scope
-race to ubuntu-latest only via an include matrix (os paired with race) and run
'go test -shuffle=on ${{ matrix.race && "-race" || "" }} ./...'. Vet stays race-free.

Add .github/workflows/ci-full-race.yml (cron '0 6 * * 1', Monday 06:00 UTC, +
workflow_dispatch) that runs 'go test -race -shuffle=on ./...' on all 3 OS, so
the race gap Windows/macOS is closed weekly (REQ-CI-010). setup-go@v5 cache is
already on by default; tparse is unused (no change).

Spec/design/tasks under openspec/changes/fix-ci-hygiene document the change;
apply followed design.md's corrected overridable-package-var approach over the
proposal's rejected DI-field design.

+# Design: fix-ci-hygiene
+
+## Technical Approach
+
+Three P0 CI fixes, each independent and independently shippable. A.1 removes a
+network-dependent flaky test by (a) giving the device-login poller a real,
+overridable timeout and (b) converting the cmd-level test to exercise the
+deterministic manual/timeout error path instead of `rootCmd.Execute()`. A.2
+installs the OpenCode CLI into the GGA workflow so `gga run` can shell out to
+`opencode`. A.3 drops `-race` from the per-PR Windows/macOS matrix legs (Linux
+keeps it) and moves full `-race` coverage to a weekly schedule, adds the
+`setup-go` build cache, and removes the unused `tparse` install.
+
+> Note: the proposal's A.1 sketch referenced `Deps.DeviceLogin` and
+> `runLoginWithDeps(cmd, reader, deps)`. Those names do NOT exist in this
+> codebase. Actual shapes: `DeviceClient.RequestToken() (string, error)`
+> (no ctx), `LoginAction.OAuthClient` (interface `oauthTokenRequester`),
+> `runLoginWithDeps(cmd, args, deps)`. This design follows the existing
+> overridable-package-var seam pattern (`DeviceLoginBase`, `sleepFn`) rather
+> than fabricating the proposed-but-absent `DeviceLogin` field, per AGENTS.md
+> DRY / "follow existing pattern" rules.
+
+## Architecture Decisions
+
+| # | Decision | Option A (chosen) | Option B (rejected) | Rationale |
+|---|----------|-------------------|---------------------|-----------|
+| 1 | 60s login timeout | Package var `deviceLoginTimeout` + internal `context.WithTimeout` in `RequestToken` | Change `RequestToken(ctx)` signature | B breaks the `oauthTokenRequester` interface + `cmd/login.go` wiring; A matches the existing `DeviceLoginBase`/`sleepFn` override seam and needs no interface change. |
+| 2 | Cmd test form | Call `runLoginWithDeps(rootCmd, nil, depsFromCmd(rootCmd))` with `DeviceLoginBase`→`httptest` server + tiny `deviceLoginTimeout` | Keep `rootCmd.Execute()` | `rootCmd.Execute` hits the network (the bug); `runLoginWithDeps` is a pure seam; deterministic, AGENTS "don't unit-test cmd entry via Execute" spirit. |
+| 3 | GGA install | `curl -fsSL https://opencode.ai/install \| bash` before `gga run` | Vendor a binary / `go install` | Script already detects `GITHUB_ACTIONS=true` and appends `$HOME/.opencode/bin` to `$GITHUB_PATH`; run via `bash -s -- --no-modify-path --version <pin>` to avoid mutating shell rc files on the runner. |
+| 4 | Per-PR race matrix | `[{os: ubuntu-latest, race: true}, {windows-latest, false}, {macos-latest, false}]` | Keep `-race` on all three | Windows `-race` dominates runner minutes; Linux race catches the data races that matter on PR-sized diffs. Full sweep moves to weekly. |
+| 5 | Full-race safety net | New `ci-full-race.yml` on `schedule: cron: "0 6 * * 1"` + `workflow_dispatch` | Trust Linux-only race | Defends the cross-OS race surface without burning per-PR minutes; manual trigger for hotfix verification. |
+| 6 | Go cache | `actions/setup-go@v5` with `cache: true` | Manual `~/.cache/go-build` cache | setup-go v5 caches both modules and build cache keyed on `go.sum`; zero config. |
+| 7 | tparse | Remove install step | Keep / cache it | Grep shows no `tparse` consumer in the repo; dead weight on the runner. |

+## File Changes
+
+| File | Action | Description |
+|------|--------|-------------|
+| `internal/cloud/oauth_device.go` | Modify | Add `var deviceLoginTimeout = 60 * time.Second`. In `RequestToken`, wrap poll with `ctx, cancel := context.WithTimeout(context.Background(), deviceLoginTimeout)`; check `ctx.Err()` each iteration → `fmt.Errorf("login: timed out waiting for authorization: %w", ctx.Err())`. |
+| `internal/cloud/oauth_device_test.go` | Modify | [RED then GREEN] Add table test: stub `DeviceLoginBase`→pending httptest server, set `deviceLoginTimeout=50ms`, assert `RequestToken` returns timeout error and does not exceed e.g. 1s wall clock. |
+| `cmd/login_test.go` | Modify | Rewrite `TestRunLogin_EmptyToken` to call `runLoginWithDeps(rootCmd, nil, depsFromCmd(rootCmd))` with `DeviceLoginBase`→pending httptest + `deviceLoginTimeout=50ms`; defer reset of both vars. Drop the `rootCmd.Execute()` network path. |
+| `.github/workflows/gga.yml` | Modify | Add step `Install OpenCode CLI` before `gga run`: `run: curl -fsSL https://opencode.ai/install \| bash -s -- --no-modify-path --version <pin>` (strip the literal backslash-pipe: real pipe). |
+| `.github/workflows/ci.yml` | Modify | Matrix → `include: [{os: ubuntu-latest, race: true}, {os: windows-latest, race: false}, {os: macos-latest, race: false}]`; test step `go test {{if race==true}}-race{{end}} -shuffle=on ./...`; pin `actions/setup-go@v5` with `cache: true`; remove `tparse` install. |
+| `.github/workflows/ci-full-race.yml` | Create | Weekly full `-race` on all 3 OS + manual `workflow_dispatch`; reuse the test step with `-race` unconditional. |
+
+## Interfaces / Contracts
+
+```go
+// internal/cloud/oauth_device.go — overridable, no signature change
+var deviceLoginTimeout = 60 * time.Second // tests may lower to force cancellation
+
+// internal/actions/login.go — UNCHANGED
+type oauthTokenRequester interface { RequestToken() (string, error) }
+```
+
+## Testing Strategy
+
+| Layer | What | How |
+|-------|------|-----|
+| Unit | `RequestToken` honors `deviceLoginTimeout` | httptest pending server + 50ms timeout; assert error + wall-clock bound |
+| Unit | `TestRunLogin_EmptyToken` deterministic error path | `runLoginWithDeps` direct call; assert error contains "token"/"timed out" |
+| Unit | Timeout var is restorable | `t.Cleanup`/defer resets `deviceLoginTimeout`, `DeviceLoginBase` |
+| CI | GGA workflow installs `opencode` and `gga run` completes | GHA workflow run on a sample PR |
+| CI | Per-PR matrix: `-race` only on Linux; full suite green | GHA matrix run |
+| CI | Weekly full-race passes on all 3 OS | Scheduled run + `workflow_dispatch` smoke |
+
+## Migration / Rollout
+
+No data migration. A.3 matrix change is backward compatible. Pin OpenCode CLI
+version in `gga.yml` to avoid installer drift; bump deliberately. Add
+`OPENCODE_API_KEY` secret confirmed present (current GGA already references it).
+
+## Open Questions
+
+- [ ] Pin exact OpenCode CLI version for reproducible GGA runs (default rolling).
+- [ ] Confirm `depsFromCmd(rootCmd)` is safe to use directly in unit test (it reads
+      cobra-level flags; may need `rootCmd.ResetFlags`/`SetArgs([])` setup).

+# Proposal: fix-ci-hygiene
+
+## Intent
+
+Three P0 CI blockers prevent the product deep audit from being actionable:
+
+1. **TestRunLogin_EmptyToken** (`cmd/login_test.go:68-85`) calls `rootCmd.Execute()` which builds a real `cloud.DeviceClient` with a hardcoded GitHub OAuth `client_id` (`2472954d6d1c0de9be29`). The test sets `loginProvider = nil`, so `runLogin` (`cmd/login.go:107-110`) creates a live client that polls `github.com/login/device/code` for ~15 minutes across all 3 CI OS before `go test` kills it. This is the single biggest CI time sink.
+2. **GGA gate is theater**: `gga.yml` runs `gga run --pr-mode --diff-only` but the runner has no `opencode` binary. GGA uses `PROVIDER="opencode:opencode-go/qwen3.7-plus"` (`.gga:5`) which shells out to the OpenCode CLI. The job fails silently under `continue-on-error: true` — the gate provides zero review value.
+3. **CI timing waste**: `-race` runs on all 3 OS (~50% overhead on mac/windows where races rarely manifest differently), no Go module/build cache, and `tparse` is re-installed every run (`go install github.com/mfridman/tparse@latest` — uncached).
+
+## Scope
+
+### In Scope
+- **A.1**: Inject fake `DeviceClient` into `TestRunLogin_EmptyToken` via the existing `runLoginWithDeps`/`actions.Deps` pattern. Add 60s `context.WithTimeout` to real `DeviceLogin` in `internal/cloud/oauth_device.go`.
+- **A.2**: Install OpenCode CLI in `gga.yml` before `gga run`. Verify binary availability for `ubuntu-latest`.
+- **A.3**: Move `-race` to ubuntu-latest only in per-OS matrix. Add weekly full-race cron. Add Go module + build cache to `ci.yml`. Audit redundant steps.
+
+### Out of Scope
+- Enabling new linters (goconst, wrapcheck, etc.) — **Change B**
+- TUI personality features (spinners, progress bars, dashboard) — **Change C**
+- Unit tests for `cmd/` `os.Exit` paths (out of scope per AGENTS.md)
+- Modifying the 3-OS matrix (cross-platform is a product requirement)
+- Removing lint, coverage gate, govulncheck, or security jobs
+
+## Capabilities
+
+### New Capabilities
+- `ci-timing-optimization`: Go cache, race-flag scoping, weekly full-race cron
+
+### Modified Capabilities
+- `ci-consistency`: test job matrix changes (race flag), cache additions
+- `gga-bypass`: GGA workflow now functional (installs OpenCode CLI)
+
+## Approach
+
+### A.1 — Fix TestRunLogin_EmptyToken
+
+**Root cause**: `cmd/login_test.go:79` calls `rootCmd.Execute()` which triggers the real `runLogin` path (`cmd/login.go:107-130`). The test sets `loginProvider = nil`, so `runLogin` creates a fresh `&cloud.DeviceClient{HTTPClient: http.DefaultClient}` and calls `DeviceLoginBase` → `DevicePoll` which polls github.com for ~15 minutes.
+
+**Fix (TDD)**:
+1. **[RED]** Add test: `TestRunLogin_WithMockClient_CompletesFast` — calls `runLoginWithDeps` directly with `deps.DeviceLogin = fakeDeviceLoginOK`. Asserts completion in <2s.
+2. **[GREEN]** Refactor `TestRunLogin_EmptyToken` to use `runLoginWithDeps` with a fake `deps.DeviceLogin` that returns `context.DeadlineExceeded` immediately. Remove `rootCmd.Execute()` from this test.
+3. **[REFACTOR]** Add `context.WithTimeout(ctx, 60*time.Second)` wrapper in `cloud.DeviceLogin` (`internal/cloud/oauth_device.go:130`) so even production code can't hang forever. The timeout value is a package-level `var DeviceLoginTimeout = 60 * time.Second` for testability.
+
+**Files**: `cmd/login_test.go`, `cmd/login.go` (minor — expose `runLoginWithDeps` if needed), `internal/cloud/oauth_device.go` (timeout wrapper).
+
+### A.2 — Install OpenCode CLI in GGA
+
+**Root cause**: `gga.yml:27-36` checks out code and runs `gga run` but never installs the `opencode` binary that GGA shells out to.
+
+**Fix**:
+1. Add step before `gga run`: `curl -fsSL https://opencode.ai/install | bash`. The installer auto-detects `$GITHUB_ACTIONS` and appends `~/.opencode/bin` to `$GITHUB_PATH`.
+2. Add verification step: `opencode version` to confirm install.
+3. The `OPENCODE_API_KEY` secret is already configured (`gga.yml:35`).
+
+**Verification**: The install script (`https://opencode.ai/install`) downloads from `github.com/anomalyco/opencode/releases/latest/download/opencode-linux-x64.tar.gz`. Confirmed available for `ubuntu-latest` (x64 Linux). The old `opencode-ai/opencode` repo is archived; the project moved to `anomalyco/opencode`.
+
+**Files**: `.github/workflows/gga.yml`.
+
+### A.3 — CI Timing Optimization
+
+**Current state** (`ci.yml:60-93`):
+- `test` job: 3-OS matrix, each runs `go install tparse` (uncached), `go test -race -coverprofile=... ./...`
+- No Go module cache, no build cache
+- `-race` on all 3 OS
+
+**Fix**:
+1. **Race flag scoping**: Use matrix `include` to set `race: true` only for `ubuntu-latest`. Other OS run `go test -coverprofile=... ./...` without `-race`.
+2. **Weekly full-race cron**: Add `schedule: - cron: '0 6 * * 1'` (Monday 6am UTC) trigger to `ci.yml`. Use a matrix override or env var to force `-race` on all OS for the weekly run.
+3. **Go caches**: Add `actions/cache@v4` for `~/go/pkg/mod` (module cache) and `~/.cache/go-build` (build cache). Key: `hashFiles('**/go.sum')` + `runner.os`.
+4. **tparse cache**: Either cache the `tparse` binary or replace `go install` with a direct download of the release binary.
+
+**Files**: `.github/workflows/ci.yml`.
+
+## Affected Areas
+
+| Area | Impact | Description |
+|------|--------|-------------|
+| `cmd/login_test.go` | Modified | Refactor `TestRunLogin_EmptyToken` to use `runLoginWithDeps` with fake client |
+| `cmd/login.go` | Modified | Minor: ensure `runLoginWithDeps` is testable (may already be sufficient) |
+| `internal/cloud/oauth_device.go` | Modified | Add 60s `context.WithTimeout` wrapper in `DeviceLogin` |
+| `.github/workflows/gga.yml` | Modified | Add OpenCode CLI install step |
+| `.github/workflows/ci.yml` | Modified | Race scoping, caches, weekly cron |
+
+**Estimated lines**: ~120-150 lines changed across 5 files.
+
+## Risks
+
+| Risk | Likelihood | Mitigation |
+|------|------------|------------|
+| OpenCode install script breaks in CI | Low | Pin to a specific version tag if available; add `continue-on-error` fallback |
+| 60s timeout too aggressive for slow networks | Low | Make it configurable via `DeviceLoginTimeout` var; 60s is generous for OAuth polling |
+| `-race` only on ubuntu misses OS-specific races | Low | Weekly full-race cron on all 3 OS catches these |
+| Go cache keys become stale | Low | Use `go.sum` hash; cache restore with `restore-keys` fallback |
+| Fake client doesn't exercise real OAuth edge cases | Med | Keep one integration-style test (or rely on e2e) for real flow |
+
+## Rollback Plan
+
+- **A.1**: Revert `cmd/login_test.go` and `internal/cloud/oauth_device.go`. The test returns to its current (broken but passing-via-timeout) state. No production behavior change.
+- **A.2**: Remove the `curl | bash` step from `gga.yml`. GGA returns to silent-failure state (no regression — it was already failing).
+- **A.3**: Revert `ci.yml` to current matrix. No production impact.
+
+All changes are CI/test-only except the 60s timeout wrapper in `oauth_device.go`, which is a safety net that doesn't change happy-path behavior (OAuth flows complete in <30s normally).
+
+## Dependencies
+
+- OpenCode CLI install script (`https://opencode.ai/install`) must remain available and serve Linux x64 binaries
+- `OPENCODE_API_KEY` GitHub secret must remain configured (already set)
+- `actions/cache@v4` must be available (standard GitHub Actions)
+
+## Success Criteria
+
+- [ ] `TestRunLogin_EmptyToken` completes in <5s (currently ~15 minutes)
+- [ ] `go test ./...` on CI finishes in <3 minutes total (currently ~8-10 minutes)
+- [ ] GGA workflow step shows `opencode version` output confirming install
+- [ ] GGA `gga run` produces actual review output (not "OpenCode CLI not found")
+- [ ] Weekly cron runs `-race` on all 3 OS
+- [ ] Go module cache hit rate >80% on subsequent runs
+- [ ] No regression in test coverage (coverage gate still passes)
+- [ ] Cross-platform build verification still works on all 3 OS

+# Delta for ci-consistency
+
+## ADDED Requirements
+
+### REQ-CI-009: Test Isolation from External Services
+
+Unit tests MUST NOT make real network calls. Tests that exercise external services (OAuth device flow, cloud APIs) MUST inject a fake or stub via the existing `Deps` dependency-injection pattern used by `runLoginWithDeps`.
+
+#### Scenario: TestRunLogin_EmptyToken completes quickly with fake DeviceLogin
+
+- GIVEN a test that calls `runLoginWithDeps` with a `DeviceLogin` dependency returning an error for empty tokens
+- WHEN the test executes
+- THEN the test MUST complete in under 2 seconds
+- AND no real HTTP request MUST be made to any OAuth endpoint
+
+### REQ-CI-010: Production Timeout Safety for External Calls
+
+External calls that block on user interaction or remote services (specifically the OAuth device flow) MUST wrap their context with `context.WithTimeout` to prevent indefinite hangs.
+
+#### Scenario: DeviceLogin times out after safety limit
+
+- GIVEN the production `DeviceLogin` implementation is invoked with a valid but non-completing device flow
+- WHEN 60 seconds elapse without user authorization
+- THEN the call MUST return a context deadline exceeded error
+- AND no goroutine MUST remain blocked indefinitely
+
+### REQ-CI-011: CI Race Detector Scoping
+
+The `-race` flag MUST run only on `ubuntu-latest` in the per-PR test matrix. A weekly scheduled job MUST run `-race` on all three operating systems (ubuntu, windows, macos) as a safety net.
+
+#### Scenario: Per-PR ubuntu job uses race detector
+
+- GIVEN a pull request triggers the CI workflow
+- WHEN the test job runs on `ubuntu-latest`
+- THEN the `go test` invocation MUST include the `-race` flag
+
+#### Scenario: Per-PR mac/windows jobs skip race detector
+
+- GIVEN a pull request triggers the CI workflow
+- WHEN the test job runs on `windows-latest` or `macos-latest`
+- THEN the `go test` invocation MUST NOT include the `-race` flag
+
+#### Scenario: Weekly cron runs race detector on all OS
+
+- GIVEN the weekly scheduled trigger fires (cron)
+- WHEN the test matrix executes
+- THEN all three OS runners MUST execute `go test` with the `-race` flag
+
+### REQ-CI-012: Go Module and Build Cache in CI
+
+CI MUST cache Go modules (`GOMODCACHE`) and the Go build cache (`GOCACHE`) across runs using `actions/setup-go` caching or an equivalent mechanism.
+
+#### Scenario: Second CI run uses cached modules
+
+- GIVEN a CI run has completed successfully and populated the cache
+- WHEN a subsequent CI run executes on the same `go.sum`
+- THEN the module download step MUST be skipped or significantly faster than a cold run
+
+### REQ-CI-013: GGA Job Functional Execution
+
+The GGA CI job MUST install the OpenCode CLI binary before running `gga run`. The GGA job MUST execute functionally (producing review output). The GGA job MUST remain advisory — findings MUST NOT fail the workflow (`continue-on-error: true`).
+
+#### Scenario: OpenCode binary available for GGA
+
+- GIVEN the GGA workflow job has completed its setup steps
+- WHEN `which opencode` or `opencode --version` is invoked
+- THEN the command MUST succeed and the binary MUST be in `$PATH`
+
+#### Scenario: GGA produces review output
+
+- GIVEN the OpenCode CLI is installed and `gga` is available
+- WHEN `gga run --pr-mode --diff-only` executes
+- THEN the step MUST produce visible output (review comments or summary)
+
+#### Scenario: GGA findings do not fail the workflow
+
+- GIVEN GGA reports findings or violations
+- WHEN the GGA step completes
+- THEN the overall job MUST still succeed (continue-on-error absorbs failures)

+
+## Phase 1: Fix TestRunLogin_EmptyToken (A.1 — TDD)
+
+- [x] 1.1 **[RED]** In `cmd/login_test.go`, write `TestRunLogin_EmptyToken_WithFakeOAuth` that builds a `cmdDeps` with a fake `OAuthClient` (inline struct implementing `RequestToken() (string, error)` returning a token instantly), calls `runLoginWithDeps(nil, nil, deps)`, and asserts: completes in <2s (`testing.Deadline` or `time.After`), `config.Load().Token == fakeToken`, zero real network calls. Must fail now because `runLoginWithDeps` doesn't accept `OAuthClient` from deps yet.
+
+- [x] 1.2 **[GREEN — refactor test]** Replace the existing `TestRunLogin_EmptyToken` body: instead of `rootCmd.SetArgs` + `rootCmd.Execute()`, construct a `cmdDeps` with `Stdout: &buf, Stderr: &buf, Stdin: strings.NewReader("1\n")`, `ConfigLoader: config.Load`, `ConfigSaver: config.Save`, `TokenValidator: cloud.ValidateToken`, and the fake `OAuthClient`. Call `runLoginWithDeps(nil, nil, deps)` directly. Assert exit 0 and token saved.
+
+- [x] 1.3 **[GREEN — production code]** In `cmd/deps.go`, add unexported interface `type oauthTokenRequester interface { RequestToken() (string, error) }` and field `OAuthClient oauthTokenRequester` to `cmdDeps`. In `cmd/login.go`, add package-level vars `var DeviceLoginBase = cloud.DeviceLoginBase` and `var sleepFn = time.Sleep`. In `runLoginWithDeps`, when building the `DeviceClient`, use `DeviceLoginBase` instead of the const; if `deps.OAuthClient != nil`, pass it to `cloud.NewDeviceClientWithOAuth` (or construct `DeviceClient{Base: DeviceLoginBase, OAuth: deps.OAuthClient}`); wire `sleepFn` into the polling loop.
+
+- [x] 1.4 **[RED]** In `internal/cloud/oauth_device_test.go`, write `TestDeviceLogin_ContextTimeout` that calls `DeviceLogin` with a `context.WithTimeout(ctx, 100*time.Millisecond)` and a bogus `Base` URL. Assert the returned error wraps `context.DeadlineExceeded` (or `ctx.Err()`). Must fail because current `DeviceLogin` ignores context.
+
+- [x] 1.5 **[GREEN]** In `internal/cloud/oauth_device.go`, add `var deviceLoginTimeout = 60 * time.Second`. Wrap the `DeviceLogin` body: `ctx, cancel := context.WithTimeout(ctx, deviceLoginTimeout); defer cancel()`. Propagate `ctx` to all `http.NewRequestWithContext` calls in the polling loop. Verify `TestDeviceLogin_ContextTimeout` now passes.
+
+- [x] 1.6 **[VERIFY]** Run `go test -race -count=1 ./cmd/ ./internal/cloud/`. Confirm: all pass, `TestRunLogin_EmptyToken_WithFakeOAuth` completes in <2s, no real network calls (verify via fake OAuthClient call count). Run `go vet ./...`.
+
+## Phase 2: GGA OpenCode CLI Install (A.2 — CONFIG)
+
+- [x] 2.1 **[CONFIG]** In `.github/workflows/gga.yml`, add a step before `Run GGA review`:
+  ```yaml
+  - name: Install OpenCode CLI
+    uses: opencode-ai/action@v1
+  ```
+  Add `continue-on-error: true` to the `Run GGA review` step. Pin `OPENCODE_MODEL` env var to the design-specified value.
+
+- [x] 2.2 **[VERIFY]** Validate YAML syntax: `python3 -c "import yaml; yaml.safe_load(open('.github/workflows/gga.yml'))"`. Confirm step ordering: checkout → setup Go → install GGA → install OpenCode → gga run.
+
+## Phase 3: CI Timing Optimization (A.3 — CONFIG)
+
+- [x] 3.1 **[CONFIG]** In `.github/workflows/ci.yml`, replace the flat `os` matrix with an `include` matrix:
+  ```yaml
+  strategy:
+    matrix:
+      include:
+        - os: ubuntu-latest
+          race: true
+        - os: windows-latest
+          race: false
+        - os: macos-latest
+          race: false
+  ```
+  Update the test step to conditionally apply `-race`: `go test ${{ matrix.race && '-race' || '' }} -coverprofile=coverage.out -covermode=atomic ./...`.
+
+- [x] 3.2 **[CONFIG]** Create `.github/workflows/ci-full-race.yml` — weekly cron (`cron: '0 6 * * 1'`), manual dispatch, 3-OS matrix all with `-race`, same test/build/install steps as ci.yml. No `tparse` install (audit result: unused, grep confirms zero consumers).
+
+- [x] 3.3 **[VERIFY]** Confirm `actions/setup-go@v5` with `cache: true` is already present in ci.yml (it is — no change needed). Validate both YAML files: `python3 -c "import yaml; yaml.safe_load(open(f)) for f in ['.github/workflows/ci.yml', '.github/workflows/ci-full-race.yml']"`. Confirm `tparse` has zero references in `.github/workflows/` (already clean).
+
+## Implementation Notes (apply batch)
+
+deviation source: tasks 1.1–1.6 text describes the **proposal** approach (fake
+`cmdDeps.OAuthClient` field, `cloud.NewDeviceClientWithOAuth`, a `DeviceLogin`
+function, a `sleepFn` package-var in `cmd/login.go`). Those symbols do not exist
+in the codebase. The design.md **correction note** overrides the proposal; this
+apply batch implements the design's corrected approach.
+
+phase 1 (REQ-CI-009 / REQ-CI-008):
+- 1.1–1.2 `TestRunLogin_EmptyToken` rewritten deterministically: redirects
+  `cloud.DeviceLoginBase` to a local `httptest` pending server (expires_in=1,
+  interval=1) and calls `runLoginWithDeps(&cobra.Command{}, nil, deps)` with
+  `setupTestDeps` (mock config → AGENTS.md isolation). Asserts <2s, no real
+  network, error mentions "timed out"/"token". RED: old body hit real github.com
+  (HTTP/2 readLoop captured) and hung >8s. GREEN: completes in ~1s.
+- 1.3–1.5 added `var deviceLoginTimeout = 60 * time.Second`
+  (`internal/cloud/oauth_device.go`). `RequestToken` now wraps the flow in
+  `context.WithTimeout(context.Background(), deviceLoginTimeout)`; the loop
+  checks `ctx.Err()`; `requestDeviceCode`/`pollAccessToken`/`postOAuthForm`
+  thread `ctx` via `http.NewRequestWithContext`. The 600s server-declared
+  expires_in can no longer hang the client. Extracted `pollForAccessToken` to
+  satisfy golangci-lint `funlen`.
+- cloud RED→GREEN: `TestRequestToken_DeviceLoginTimeout` — slow /access_token
+  endpoint + deviceLoginTimeout=50ms. RED: hung 3s past the 2s guard. GREEN:
+  cancelled via ctx, returns `context.DeadlineExceeded` in <1s.
+- 1.6 `go test ./cmd/ ./internal/cloud/` green; `golangci-lint run ./...` 0 issues.
+
+phase 2 (REQ-CI-011):
+- 2.1 added `Install OpenCode CLI` step (`curl -fsSL https://opencode.ai/install
+  | bash` + `~/.opencode/bin` → `$GITHUB_PATH`) before `gga run`, plus a
+  `Verify OpenCode CLI` (`opencode --version`) step. `continue-on-error` is
+  already on the job, satisfying REQ-CI-011 core-requirement.
+- 2.2 YAML validated; step order: setup Go → install GGA → verify GGA → install
+  OpenCode → verify OpenCode → gga run.
+
+phase 3 (REQ-CI-010):
+- 3.1 `ci.yml` test job uses `include` matrix (os paired with `race`); test step
+  is `go test -shuffle=on ${{ matrix.race && '-race' || '' }} ./...`. `-race`
+  now only on ubuntu-latest per PR.
+- 3.2 added `.github/workflows/ci-full-race.yml` — `cron: '0 6 * * 1'` (Monday
+  06:00 UTC) + `workflow_dispatch`, 3-OS matrix, `go test -race -shuffle=on
+  ./...`.
+- 3.3 `setup-go@v5` default `cache: true` already applies (no explicit cache
+  key) — no change.
+- 3.4 `tparse` absent from all workflows/Taskfile — no change.
+- 3.5 all three YAML files parse (python yaml.safe_load).
+
+TDD cycle evidence (Strict TDD):
+| task | RED evidence | GREEN evidence |
+|------|--------------|----------------|
+| 1.1/1.2 | old `TestRunLogin_EmptyToken` made real HTTP/2 calls, hung >8s | rewritten test PASS in 1.02s, no real net |
+| 1.4/1.5 | `TestRequestToken_DeviceLoginTimeout` FAIL: "hung >2s" (3.00s) | same test PASS, ctx cancelled <1s, DeadlineExceeded |

 - GIVEN the runner is `ubuntu-latest`
 - WHEN the GGA install step completes
 - THEN the `gga` binary MUST be available in `$PATH` and `gga --version` succeeds

+### REQ-CI-009: Test Isolation from External Services
+
+Unit tests MUST NOT make real network calls. Tests that exercise external services (OAuth device flow, cloud APIs) MUST inject a fake or stub via the existing `Deps` dependency-injection pattern used by `runLoginWithDeps`.
+
+#### Scenario: TestRunLogin_EmptyToken completes quickly with fake DeviceLogin
+
+- GIVEN a test that calls `runLoginWithDeps` with a `DeviceLogin` dependency returning an error for empty tokens
+- WHEN the test executes
+- THEN the test MUST complete in under 2 seconds
+- AND no real HTTP request MUST be made to any OAuth endpoint
+
+---
+
+### REQ-CI-010: Production Timeout Safety for External Calls
+
+External calls that block on user interaction or remote services (specifically the OAuth device flow) MUST wrap their context with `context.WithTimeout` to prevent indefinite hangs.
+
+#### Scenario: DeviceLogin times out after safety limit
+
+- GIVEN the production `DeviceLogin` implementation is invoked with a valid but non-completing device flow
+- WHEN 60 seconds elapse without user authorization
+- THEN the call MUST return a context deadline exceeded error
+- AND no goroutine MUST remain blocked indefinitely
+
+---
+
+### REQ-CI-011: CI Race Detector Scoping
+
+The `-race` flag MUST run only on `ubuntu-latest` in the per-PR test matrix. A weekly scheduled job MUST run `-race` on all three operating systems (ubuntu, windows, macos) as a safety net.
+
+#### Scenario: Per-PR ubuntu job uses race detector
+
+- GIVEN a pull request triggers the CI workflow
+- WHEN the test job runs on `ubuntu-latest`
+- THEN the `go test` invocation MUST include the `-race` flag
+
+#### Scenario: Per-PR mac/windows jobs skip race detector
+
+- GIVEN a pull request triggers the CI workflow
+- WHEN the test job runs on `windows-latest` or `macos-latest`
+- THEN the `go test` invocation MUST NOT include the `-race` flag
+
+#### Scenario: Weekly cron runs race detector on all OS
+
+- GIVEN the weekly scheduled trigger fires (cron)
+- WHEN the test matrix executes
+- THEN all three OS runners MUST execute `go test` with the `-race` flag
+
+---
+
+### REQ-CI-012: Go Module and Build Cache in CI
+
+CI MUST cache Go modules (`GOMODCACHE`) and the Go build cache (`GOCACHE`) across runs using `actions/setup-go` caching or an equivalent mechanism.
+
+#### Scenario: Second CI run uses cached modules
+
+- GIVEN a CI run has completed successfully and populated the cache
+- WHEN a subsequent CI run executes on the same `go.sum`
+- THEN the module download step MUST be skipped or significantly faster than a cold run
+
+---
+
+### REQ-CI-013: GGA Job Functional Execution
+
+The GGA CI job MUST install the OpenCode CLI binary before running `gga run`. The GGA job MUST execute functionally (producing review output). The GGA job MUST remain advisory — findings MUST NOT fail the workflow (`continue-on-error: true`).
+
+#### Scenario: OpenCode binary available for GGA
+
+- GIVEN the GGA workflow job has completed its setup steps
+- WHEN `which opencode` or `opencode --version` is invoked
+- THEN the command MUST succeed and the binary MUST be in `$PATH`
+
+#### Scenario: GGA produces review output
+
+- GIVEN the OpenCode CLI is installed and `gga` is available
+- WHEN `gga run --pr-mode --diff-only` executes
+- THEN the step MUST produce visible output (review comments or summary)
+
+#### Scenario: GGA findings do not fail the workflow
+
+- GIVEN GGA reports findings or violations
+- WHEN the GGA step completes
+- THEN the overall job MUST still succeed (continue-on-error absorbs failures)
