Phase 02 Plan 02: Env Audit Display and Confirmation Prompt Summary

Pre-launch env audit with grouped sections (sandbox/host/extra), sensitive value masking, PATH splitting, and interactive Y/n confirmation with TTY detection.

Completed Tasks

#	Task	Commit	Key Changes
1	Add parallel display arrays and env audit display function	1c986d2	ANSI colors with NO_COLOR support, mask_value(), AUDIT_*_KEYS/VALS arrays, print_audit() with grouped sections and PATH splitting
2	Add confirmation prompt with TTY detection	b035f82	Proceed? [Y/n] prompt, TTY check via -t 0 , non-TTY abort with actionable error, guarded by SKIP_AUDIT and DRY_RUN

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] shellcheck SC2034 for RED variable

• Found during: Task 1
• Issue: RED was defined in ANSI color block but only used by Task 2's confirmation prompt code (not yet written)
• Fix: Temporarily added export RED to satisfy shellcheck, then removed it in Task 2 commit after RED gained actual usage
• Files modified: claudebox.sh
• Commit: 1c986d2 (added), b035f82 (removed)

Verification Results

• nix build succeeds (shellcheck clean)
• grep -q mask_value claudebox.sh -- present
• grep -q print_audit claudebox.sh -- present
• grep -q 'Proceed.*Y/n' claudebox.sh -- present
• grep -q 'SKIP_AUDIT.*true' claudebox.sh -- present
• Script flow order verified: flag parsing -> --check -> binary resolution -> env construction -> audit arrays -> audit+prompt -> dry-run -> exec bwrap

Threat Surface Scan

T-02-03 mitigated: mask_value() auto-masks any var name matching KEY, TOKEN, SECRET, PASSWORD, CREDENTIAL (case-insensitive via ${name^^}). T-02-04 mitigated: mask_value() applies to all displayed vars regardless of source category. T-02-05 mitigated: non-TTY stdin aborts with error, never auto-proceeds.

Self-Check: PASSED
