Phase 04: auth-passthrough Verification Report

Phase Goal: Mount ~/.claude/.credentials.json read-write into the sandbox and rewrite the pre-launch audit to a unified env/mounts/network display. Verified: 2026-04-10 Status: passed Re-verification: Yes — after gap closure

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	claudebox launches successfully when ~/.claudebox/.credentials.json exists on the host	VERIFIED	Lines 107-112: CREDS_FILE set to $HOME/.claudebox/.credentials.json; CREDS_MOUNT conditional detection; BWRAP_ARGS conditional append at lines 370-371
2	OAuth token refresh can write back to the credentials file (read-write mount)	VERIFIED	Line 371: --bind used (not --ro-bind); line 338 dry-run block also outputs --bind; print_audit line 269 shows (read-write) label
3	claudebox launches without error when ~/.claudebox/.credentials.json does not exist	VERIFIED	CREDS_MOUNT=false path: --bind simply omitted from BWRAP_ARGS; no error or warning output
4	ANTHROPIC_API_KEY is passed into the sandbox when set on the host	VERIFIED	Line 214: HOST_ALLOWLIST includes ANTHROPIC_API_KEY; conditional --setenv applied in the loop at lines 215-221
5	The audit screen shows all env vars in a single unified list with [~]/[>]/[+] prefixes	VERIFIED	print_audit lines 242-259: three loops — sandbox [~] (green), host [>] (yellow), extra [+] (cyan) — with literal text prefixes
6	The audit screen shows a Mounts section and a Network section after the env list	VERIFIED	Lines 265-276: Mounts section (CWD, ~/.claude, conditional credentials with read-write label); Network section ("full (host network)")
7	The --dry-run output mirrors the credential bind when the file exists	VERIFIED	Lines 337-338: conditional block prints --bind $CREDS_FILE $HOME/.claudebox/.credentials.json when CREDS_MOUNT=true

Score: 7/7 truths verified

Required Artifacts

Artifact	Expected	Status	Details
claudebox.sh	Credential mount logic, updated print_audit, updated --dry-run block	VERIFIED	File exists (383 lines), substantive, all three pieces present and wired into execution path; bash -n passes

Key Link Verification

From	To	Via	Status	Details
CREDS_MOUNT detection (lines 108-112)	BWRAP_ARGS conditional append (lines 370-371)	if	WIRED	--bind used; read-write mount
CREDS_MOUNT detection	dry-run display block (lines 337-338)	if	WIRED	--bind mirrored correctly
print_audit function	AUDIT_SANDBOX_KEYS / AUDIT_HOST_KEYS / AUDIT_EXTRA_KEYS arrays	[~]/[>]/[+] prefix loops (lines 242-259)	WIRED	Three loops reading from correct audit arrays
CREDS_MOUNT	print_audit Mounts section (lines 268-270)	if	WIRED	Conditional credentials line shows (read-write) label

Data-Flow Trace (Level 4)

Not applicable — claudebox.sh is a shell launcher script. All data flows are shell variable assignments and bwrap argument construction, not rendered dynamic UI components.

Behavioral Spot-Checks

Behavior	Command	Result	Status
Script syntax valid	bash -n claudebox.sh	SYNTAX OK	PASS
Credential bind is read-write (not read-only)	grep --bind.*credentials claudebox.sh	Lines 338, 371 confirm --bind	PASS
No --ro-bind on credentials	grep ro-bind.*credentials claudebox.sh	No output	PASS
[~]/[>]/[+] prefixes present	grep pattern in print_audit	Lines 244, 250, 255, 259	PASS
Mounts and Network sections present	lines 265, 275	Both sections confirmed	PASS
print_audit credentials label says read-write	grep read-write claudebox.sh	Lines 266, 267, 269	PASS

Requirements Coverage

Requirement	Source	Description	Status	Evidence
AUTH-01	REQUIREMENTS.md v2, Phase 4	~/.claudebox/.credentials.json bind-mounted read-write when file exists	SATISFIED	Defined in REQUIREMENTS.md lines 61-62; implemented at claudebox.sh lines 107-112, 370-371; traceability entry at line 128
AUTH-02	REQUIREMENTS.md v2, Phase 4	Silent skip when credentials file absent	SATISFIED	Defined in REQUIREMENTS.md lines 63-64; implemented at claudebox.sh line 111 (CREDS_MOUNT=false); traceability entry at line 129

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
claudebox.sh	276	"full (host network)" placeholder	Info	Intentional Phase 6 placeholder; documented in SUMMARY known stubs

Human Verification Required

None. All must-haves are verified programmatically.

Gaps Summary

No gaps. Both gaps from the initial verification are closed:

Gap 1 (closed): Credential mount is now --bind (read-write) in both the actual BWRAP_ARGS (line 371) and the dry-run display block (line 338). The print_audit mounts section labels credentials as (read-write). The WR-01 code-review change that had introduced --ro-bind was reverted per the plan's original intent (OAuth refresh requires write access).

Gap 2 (closed): AUTH-01 and AUTH-02 are now defined in REQUIREMENTS.md under the v2 "Authentication Passthrough" section with full descriptions and traceability table entries showing Phase 4 / Complete.
