# Phase 2: Env Audit and CLI Polish Verification Report

**Phase Goal:** User can review exactly what enters the sandbox before launch, and has diagnostic tools for troubleshooting
**Verified:** 2026-04-09T16:00:00Z
**Status:** human_needed
**Re-verification:** No -- initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Running `claudebox` without `--yes` prints all env vars and prompts for confirmation | VERIFIED | `print_audit()` at lines 175-211, prompt at line 219, guarded by `SKIP_AUDIT != true && DRY_RUN != true` at line 214 |
| 2 | Running `claudebox --yes` or `-y` skips env audit and launches immediately | VERIFIED | Flag parsing at line 10 sets `SKIP_AUDIT=true`, guard at line 214 checks it |
| 3 | Running `claudebox --dry-run` prints full bwrap command without executing | VERIFIED | Lines 240-272: prints all --setenv triplets, mount flags, sandbox command, then `exit 0` |
| 4 | Running `claudebox --check` reports whether bwrap, Nix packages, ~/.claudebox exist | VERIFIED | Lines 22-63: `check_cmd` for bwrap/claude/git/curl/nix, dir check for ~/.claudebox, ANTHROPIC_API_KEY warn |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `claudebox.sh` | Refactored flag parsing, --check, --dry-run (Plan 01) | VERIFIED | 299 lines, contains CHECK_MODE, DRY_RUN, SKIP_AUDIT, CLAUDE_ARGS (15 pattern matches) |
| `claudebox.sh` | Env audit display, masking, confirmation prompt (Plan 02) | VERIFIED | Contains mask_value, print_audit, Proceed (7 pattern matches) |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| Flag parsing (CLAUDE_ARGS) | SANDBOX_CMD construction | `CLAUDE_ARGS` array replaces raw `$@` | WIRED | Declared line 6, accumulated lines 14-15, used in SANDBOX_CMD lines 234, 236 |
| Env audit block | SKIP_AUDIT flag | `if [[ "$SKIP_AUDIT" != true ]]` | WIRED | Set line 2/10, checked line 214 |
| Audit display | ENV_ARGS array | Parallel AUDIT_*_KEYS/VALS arrays | WIRED | AUDIT_SANDBOX/HOST/EXTRA arrays declared lines 120-125, populated lines 141-169, displayed in print_audit lines 175-211 |

### Data-Flow Trace (Level 4)

Not applicable -- shell script with no dynamic data rendering. All data flows from flag parsing and host environment through to bwrap execution, verified via wiring checks above.

### Behavioral Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| nix build passes (shellcheck clean) | `nix build` | exit 0 | PASS |
| No TODO/FIXME/PLACEHOLDER markers | `grep -n TODO\|FIXME\|PLACEHOLDER claudebox.sh` | 0 matches | PASS |
| Flag parsing handles multiple flags | grep for while/shift loop | `while (( $# > 0 ))` at line 8 with case/esac | PASS |
| Mask function covers all sensitive patterns | grep mask_value body | KEY, TOKEN, SECRET, PASSWORD, CREDENTIAL all present | PASS |
| Stderr-only output | grep `>&2` count | 28 stderr redirections found | PASS |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| UX-01 | 02-02 | Pre-launch env audit displays all env vars on stderr | SATISFIED | `print_audit()` with 3 grouped sections, all output to stderr |
| UX-02 | 02-02 | Pre-launch env audit prompts for confirmation | SATISFIED | `Proceed? [Y/n]` at line 219, abort on `n`/`no` |
| UX-03 | 02-01 | `--yes`/`-y` skips confirmation | SATISFIED | Flag parsed line 10, guard at line 214 |
| UX-04 | 02-01 | `--dry-run` prints full bwrap command | SATISFIED | Lines 240-272, multiline bwrap output to stderr, exit 0 |
| UX-05 | 02-01 | `--check` verifies prerequisites | SATISFIED | Lines 22-63, checks bwrap/claude/git/curl/nix + ~/.claudebox + ANTHROPIC_API_KEY |

No orphaned requirements found -- all 5 phase requirements (UX-01 through UX-05) are claimed and satisfied.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | - | - | - | No anti-patterns detected |

### Human Verification Required

### 1. Visual Audit Display

**Test:** Run `claudebox` in a terminal without `--yes` flag
**Expected:** Three grouped sections (Sandbox-generated, Host allowlisted, Extra) with colored headers, PATH entries split one per line, sensitive values masked (ANTHROPIC_API_KEY shows `sk-ant-...xxxx`), `Proceed? [Y/n]` prompt
**Why human:** Requires bwrap-capable environment, TTY interaction, visual confirmation of color formatting

### 2. Dry-Run Output

**Test:** Run `claudebox --dry-run`
**Expected:** Full multiline bwrap command printed to stderr with all --setenv and mount flags, exits 0
**Why human:** Requires runtime with resolved SANDBOX_PATH and binary paths

### 3. Check Mode

**Test:** Run `claudebox --check`
**Expected:** Colored OK/FAIL/WARN for each prerequisite, appropriate exit code
**Why human:** Requires nix-built binary to verify PATH resolution targets

### 4. Non-Interactive Abort

**Test:** Run `echo "" | claudebox`
**Expected:** Error message about stdin not being a terminal, suggests `--yes`/`-y`, exits 1
**Why human:** Requires runtime TTY detection test

### 5. Yes Flag Skip

**Test:** Run `claudebox --yes`
**Expected:** No audit display, sandbox launches immediately
**Why human:** Requires full sandbox environment

### Gaps Summary

No automated gaps found. All 4 roadmap success criteria verified at code level. All 5 requirements (UX-01 through UX-05) are satisfied in the implementation. The code is clean (no TODOs, no stubs, shellcheck passes via nix build).

One minor documentation note: commit hashes in 02-01-SUMMARY.md (`07096ae`, `3903667`, `cc6bd5b`) do not match actual commits (`72ba48d`, `1eddd93`, `7001303`). This is cosmetic and does not affect functionality.

Human verification is needed to confirm runtime behavior -- the code structure is correct but these are interactive CLI features that require a terminal and bwrap environment to fully validate.
