You are addressing code-review feedback on Task 2 of the birdseye CLI. Commit `3b73e14` in worktree `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye` is the target.

## What to Change

Make small, focused edits to address these review nits. Use the Edit tool. Do NOT restructure the package.

**Important — what to IGNORE:**

The reviewer flagged that `g := &GlobalFlags{}` in `NewRootCmd()` is "inaccessible to subcommands." That feedback is incorrect. The design intentionally uses a shared pointer: `g` is constructed in `NewRootCmd` and passed by pointer to subcommand constructors (`newDiffCmd(g)`, `newVersionsCmd(g)`) which will be added in later tasks. Cobra writes parsed flag values into `*g`, and subcommand constructors close over the same pointer. **Do not change this pattern.** The commented scaffold inside `NewRootCmd` already documents this intent.

## Specific Edits

### Edit 1: Add a `DeadlineExceeded` test case

In `apps/birdseye/cmd/errors_test.go`, add a row to the `TestExitCode` cases slice:

```go
{"context-deadline", context.DeadlineExceeded, 130},
```

Place it directly after the `"context-cancelled"` row.

### Edit 2: Broaden `ErrSemantic` doc

In `apps/birdseye/cmd/errors.go`, the current declaration:

```go
ErrSemantic = errors.New("HCL parse error")
```

Change to:

```go
// ErrSemantic indicates a parse or validation error during semantic
// (HCL-aware) diffing. Maps to exit code 5.
ErrSemantic = errors.New("semantic diff parse error")
```

Also add adjacent doc comments to `ErrUsage` and `ErrArchive` for parity, e.g.:

```go
// ErrUsage indicates a CLI usage error (bad args, malformed module
// address, missing TTY for interactive mode). Maps to exit code 1.
ErrUsage = errors.New("usage error")

// ErrArchive indicates the fetched module tarball was corrupt or
// contained unsafe paths. Maps to exit code 4.
ErrArchive = errors.New("archive corrupt or unsafe")
```

### Edit 3: Add explanatory comment to the `RunE` workaround

In `apps/birdseye/cmd/root.go`, the `RunE: func...` line lacks context. Add a comment above the struct literal field. Something like:

```go
// Without a RunE, cobra v1.x prints help via its internal stderr
// writer rather than the writer set by SetOut, which breaks
// TestNewRootCmdHelp's captured buffer. Calling Help() explicitly
// routes the output correctly. Subcommands will not invoke this.
RunE: func(cmd *cobra.Command, args []string) error {
    return cmd.Help()
},
```

### Edit 4: Named exit-code constants

In `apps/birdseye/cmd/errors.go`, add unexported constants for the exit codes and reference them in `ExitCode`:

```go
const (
    exitOK              = 0
    exitUsage           = 1
    exitNotFound        = 2
    exitGeneric         = 3
    exitArchive         = 4
    exitSemantic        = 5
    exitUserCancelled   = 130
)
```

Replace the bare integer returns in `ExitCode` to use these constants. Example:

```go
func ExitCode(err error) int {
    switch {
    case err == nil:
        return exitOK
    case errors.Is(err, ErrUsage):
        return exitUsage
    case errors.Is(err, client.ErrNotFound):
        return exitNotFound
    case errors.Is(err, ErrArchive):
        return exitArchive
    case errors.Is(err, ErrSemantic):
        return exitSemantic
    case errors.Is(err, context.Canceled), errors.Is(err, context.DeadlineExceeded):
        return exitUserCancelled
    default:
        return exitGeneric
    }
}
```

## After Edits

- [ ] Run `cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go test -race ./cmd/... -v` — all 8 cases (including the new `context-deadline`) must pass.
- [ ] Run `cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go build ./...` — succeeds.
- [ ] Run `cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go vet ./...` — succeeds.

- mind:memory: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- mind:mind: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).
TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.
SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.

**Status:** DONE

**Files changed:**
- `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/cmd/errors.go` — added named exit-code constants (`exitOK` … `exitUserCancelled`), replaced bare integer returns in `ExitCode`, added per-sentinel doc comments, broadened `ErrSemantic` message from `"HCL parse error"` to `"semantic diff parse error"`
- `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/cmd/errors_test.go` — added `{"context-deadline", context.DeadlineExceeded, 130}` row after the `"context-cancelled"` row
- `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/cmd/root.go` — added explanatory comment above `RunE` documenting why `cmd.Help()` is called explicitly

**Test output:** 8 cases, all PASS (including new `context-deadline`); `go build ./...` and `go vet ./...` both clean.

**Commit SHA:** `59cd0b6`

**Nothing unexpected** — `errors.go` already had the correct `context.DeadlineExceeded` branch; the only work was wiring it to the named constant and adding the test case to exercise it.
