## v2 Requirements
|
||||
|
||||
### Authentication Passthrough
|
||||
|
||||
- **AUTH-01**: `~/.claudebox/.credentials.json` (OAuth tokens) is bind-mounted read-write into the sandbox when the file exists on the host, so users do not need to re-authenticate on every launch
|
||||
- **AUTH-02**: When `~/.claudebox/.credentials.json` does not exist, claudebox starts without any error or warning (silent skip)
|
||||
|
||||
### Network Isolation
|
||||
|
||||
- **NET-01**: Block LAN/Tailscale access (RFC1918 + 100.64.0.0/10) while allowing internet egress

# Phase 4 Plan 1: Credential Mount + Audit Redesign Summary
|
||||
|
||||
**One-liner:** Read-write `~/.claude/.credentials.json` bind mount for OAuth passthrough plus unified `[~]/[>]/[+]` env audit with Mounts and Network sections.
|
||||
|
||||
## What Was Built
|
||||
|
||||
### Task 4.1.1 — Add credential file mount
|
||||
|
||||
Added conditional detection and mounting of `~/.claude/.credentials.json` into the sandbox:
|
||||
|
||||
- `CREDS_FILE` / `CREDS_MOUNT` variables set after `mkdir -p "$HOME/.claudebox"`
|
||||
- When `CREDS_MOUNT=true`: `--bind "$CREDS_FILE" "$HOME/.claude/.credentials.json"` added to bwrap args
|
||||
- Silent skip when file absent — no error or warning output
|
||||
- Uses `--bind` (not `--ro-bind`) so OAuth token refresh can write back to the file
|
||||
- `exec bwrap` refactored to use `BWRAP_ARGS` array to support the conditional mount cleanly
|
||||
- Credential bind mirrored in `--dry-run` display block
|
||||
|
||||
### Task 4.1.2 — Rewrite print_audit
|
||||
|
||||
Rewrote `print_audit` from three separate sections to a unified list:
|
||||
|
||||
- Single loop ordering: sandbox keys `[~]` (green) → host allowlisted `[>]` (yellow) → extra `[+]` (cyan)
|
||||
- Text prefixes readable without color (accessibility — D-07)
|
||||
- PATH retains multiline indented display
|
||||
- New `Mounts:` section shows CWD, `~/.claude`, and conditional credentials line
|
||||
- New `Network:` section shows `full (host network)` as Phase 6 placeholder
|
||||
- All print_audit output goes to stderr
|
||||
- `mask_value` called for every env var value in all three loops
|
||||
|
||||
## Decisions Made
|
||||
|
||||
1. **BWRAP_ARGS array:** The `exec bwrap ... \` inline form cannot have a conditional in the middle. Refactored to build a `BWRAP_ARGS` array and `exec bwrap "${BWRAP_ARGS[@]}"`. This is cleaner and extensible for future conditional mounts (network tiers, profile mounts).
|
||||
|
||||
2. **Text prefixes for accessibility:** `[~]`, `[>]`, `[+]` are printed as literal text (not just color differences). Color is additive — the prefix meaning is clear in monochrome terminals and when piped.
|
||||
|
||||
3. **CREDS_MOUNT scoping:** `CREDS_MOUNT` is set at script top-level (before `print_audit`), so the Mounts section in `print_audit` can read it without needing to re-check the filesystem.

|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 1 - Refactor] Refactored exec bwrap to BWRAP_ARGS array**
|
||||
|
||||
- **Found during:** Task 4.1.1
|
||||
- **Issue:** The `exec bwrap ... \` inline multi-line form cannot include a conditional mount (`if [[ "$CREDS_MOUNT" == true ]]; then ... fi`) in the middle of the argument list.
|
||||
- **Fix:** Replaced the inline `exec bwrap` form with a `BWRAP_ARGS` array built up with conditional appends, then `exec bwrap "${BWRAP_ARGS[@]}"`. This preserves identical runtime behavior while enabling conditional mounts.
|
||||
- **Files modified:** claudebox.sh
|
||||
- **Commit:** 6465da8
|
||||
|
||||
## Known Stubs
|
||||
|
||||
- **Network section:** `full (host network)` in `print_audit` is an intentional Phase 4 placeholder. Network isolation tiers will replace this in Phase 6.
|
||||
|
||||
## Threat Flags
|
||||
|
||||
| Flag | File | Description |
|
||||
|------|------|-------------|
|
||||
| threat_flag: credential-exfil | claudebox.sh | Read-write bind of `~/.claude/.credentials.json` gives sandbox read access to OAuth tokens; sandbox has full host network, so exfiltration is possible. Accepted risk per plan threat model — Phase 6 network tiers reduce surface. |

## Fixed Issues
|
||||
|
||||
### CR-01: CREDS_FILE path resolves against the wrong directory on the host
|
||||
|
||||
**Files modified:** `claudebox.sh`
|
||||
**Commit:** adb9dd1
|
||||
**Applied fix:** Changed `CREDS_FILE` from `$HOME/.claude/.credentials.json` to `$HOME/.claudebox/.credentials.json`. Added comments explaining that the `~/.claude -> ~/.claudebox` symlink only exists inside the sandbox at runtime, so host-side credential detection must use the real claudebox config directory path.
|
||||
|
||||
---
|
||||
|
||||
### CR-02: Credentials bind target uses a symlink path — may silently fail
|
||||
|
||||
**Files modified:** `claudebox.sh`
|
||||
**Commit:** adb9dd1
|
||||
**Applied fix:** Changed the `BWRAP_ARGS` credential bind destination from `$HOME/.claude/.credentials.json` (symlink path, unresolvable by bwrap at bind time) to `$HOME/.claudebox/.credentials.json` (canonical real directory). Also updated the `--dry-run` output block to print the corrected destination path.
|
||||
|
||||
---
|
||||
|
||||
### WR-01: Credentials file mounted read-write instead of read-only
|
||||
|
||||
**Files modified:** `claudebox.sh`
|
||||
**Commit:** adb9dd1
|
||||
**Applied fix:** Changed `--bind` to `--ro-bind` for the credentials bind in both the `BWRAP_ARGS` array (line ~366) and the `--dry-run` output block (line ~333). Also updated the `print_audit` mounts display to show `(read-only)` and display `$CREDS_FILE` (the actual host source path) instead of the hardcoded symlink path inside the sandbox.
|
||||
|
||||
---
|
||||
|
||||
### WR-02: dry-run ENV_ARGS loop hard-codes stride of 3 — breaks if any non-setenv arg is added
|
||||
|
||||
**Files modified:** `claudebox.sh`
|
||||
**Commit:** 0922b75
|
||||
**Applied fix:** Added a guard assertion before the stride-3 loop that checks `${#ENV_ARGS[@]} % 3 != 0` and exits with a `BUG:` message if the invariant is violated. This catches any future breakage immediately rather than producing silently mangled output. Also changed `(( dry_run_i += 3 ))` to `dry_run_i=$(( dry_run_i + 3 ))` to use safe arithmetic assignment compatible with `set -euo pipefail` (which `writeShellApplication` enables).

## Summary
|
||||
|
||||
This review covers the phase 4 credential passthrough changes to `claudebox.sh`. The diff introduces AUTH-01/AUTH-02: detecting `~/.claude/.credentials.json` on the host and conditionally bind-mounting it into the sandbox. The refactor also converts the inline `exec bwrap ...` to a `BWRAP_ARGS` array for conditional mount support, and unifies the env audit display format.
|
||||
|
||||
Two critical issues were found: the credential path resolution is wrong on any system where `~/.claude` and `~/.claudebox` are different directories (the detection silently fails with `CREDS_MOUNT=false`), and the credential file is mounted read-write when read-only is correct. A mount-ordering issue with the symlink target path may also prevent the credentials bind from working at all on some bwrap versions.
|
||||
|
||||
---
|
||||
|
||||
## Critical Issues
|
||||
|
||||
### CR-01: CREDS_FILE path resolves against the wrong directory on the host
|
||||
|
||||
**File:** `claudebox.sh:105`
|
||||
|
||||
**Issue:** `CREDS_FILE` is set to `$HOME/.claude/.credentials.json`. On the host, `~/.claude` is the real Claude config directory — **not** `~/.claudebox`. The symlink `~/.claude -> ~/.claudebox` only exists *inside* the sandbox (it is created by the `--symlink` bwrap flag at runtime). Before the sandbox is entered, `$HOME/.claude` and `$HOME/.claudebox` are independent paths.
|
||||
|
||||
If the user's credentials live in `~/.claude/.credentials.json` (the default Claude Code location) and `~/.claudebox` is a separate directory, the `-f "$CREDS_FILE"` test on line 106 may still succeed — but the file being tested and the file actually mounted will be the real `~/.claude/.credentials.json`, which is then bound into `$HOME/.claude/.credentials.json` inside the sandbox. Since the sandbox maps `$HOME/.claudebox` → `$HOME/.claude` (symlink), the bind target `$HOME/.claude/.credentials.json` is a symlink path that bwrap must traverse, creating the mount-ordering hazard in CR-02.
|
||||
|
||||
More importantly, if the intent is to read credentials from `~/.claudebox/.credentials.json` (i.e. the claudebox-managed config dir), the detection path is wrong and will silently miss it. The correct host path to check is:
|
||||
|
||||
```bash
|
||||
# Correct: resolve against the claudebox config dir, not ~/.claude
|
||||
CREDS_FILE="$HOME/.claudebox/.credentials.json"
|
||||
```
|
||||
|
||||
If the intent is to read from the real `~/.claude`, that is correct as written, but then the mount target inside the sandbox must use the canonical path, not the symlink path (see CR-02).
|
||||
|
||||
**Fix:**
|
||||
|
||||
Choose one consistent interpretation. If credentials come from `~/.claudebox`:
|
||||
|
||||
```bash
|
||||
CREDS_FILE="$HOME/.claudebox/.credentials.json"
|
||||
if [[ -f "$CREDS_FILE" ]]; then
|
||||
CREDS_MOUNT=true
|
||||
else
|
||||
CREDS_MOUNT=false
|
||||
fi
|
||||
```
|
||||
|
||||
And mount it to the canonical destination (not through the symlink):
|
||||
|
||||
```bash
|
||||
BWRAP_ARGS+=(--ro-bind "$CREDS_FILE" "$HOME/.claudebox/.credentials.json")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### CR-02: Credentials bind target uses a symlink path — may silently fail
|
||||
|
||||
**File:** `claudebox.sh:364`
|
||||
|
||||
**Issue:** The credentials bind is:
|
||||
|
||||
```bash
|
||||
--bind "$CREDS_FILE" "$HOME/.claude/.credentials.json"
|
||||
```
|
||||
|
||||
Inside the bwrap namespace, `$HOME/.claude` is a symlink (created by `--symlink "$HOME/.claudebox" "$HOME/.claude"` on line 361). Bwrap processes mount arguments in order and creates the symlink before this bind, but bwrap does **not** resolve symlinks in the destination path when applying `--bind` — it uses the literal path. The literal path `$HOME/.claude/.credentials.json` refers to a path whose parent is a dangling symlink at mount time (the symlink exists, but the directory component `$HOME/.claude/` is not a real directory). This means the bind either silently fails or errors, depending on bwrap version.
|
||||
|
||||
The fix is to bind the file directly into the canonical directory path `$HOME/.claudebox/.credentials.json`, which is the real directory:
|
||||
|
||||
```bash
|
||||
# Wrong: target is through a symlink
|
||||
BWRAP_ARGS+=(--bind "$CREDS_FILE" "$HOME/.claude/.credentials.json")
|
||||
|
||||
# Correct: target is the real directory
|
||||
BWRAP_ARGS+=(--ro-bind "$CREDS_FILE" "$HOME/.claudebox/.credentials.json")
|
||||
```
|
||||
|
||||
The same fix applies to the `--dry-run` output path on line 331.
|
||||
|
||||
---
|
||||
|
||||
## Warnings
|
||||
|
||||
### WR-01: Credentials file mounted read-write instead of read-only
|
||||
|
||||
**File:** `claudebox.sh:364`
|
||||
|
||||
**Issue:** `--bind` creates a read-write mount. Claude Code needs to **read** credentials, not write them. Mounting the credentials file read-write gives the sandboxed agent the ability to overwrite or corrupt the host's credential store. This contradicts the project's principle of least privilege — the sandbox should only receive what it needs.
|
||||
|
||||
**Fix:**
|
||||
|
||||
```bash
|
||||
# Change --bind to --ro-bind
|
||||
BWRAP_ARGS+=(--ro-bind "$CREDS_FILE" "$HOME/.claudebox/.credentials.json")
|
||||
```
|
||||
|
||||
The same applies in the `--dry-run` output block (line 331) — update `--bind` to `--ro-bind` there for accurate documentation of actual behavior.
|
||||
|
||||
---
|
||||
|
||||
### WR-02: dry-run ENV_ARGS loop hard-codes stride of 3 — breaks if any non-setenv arg is added
|
||||
|
||||
**File:** `claudebox.sh:309-312`
|
||||
|
||||
**Issue:** The dry-run printer iterates `ENV_ARGS` with a fixed stride of 3:
|
||||
|
||||
```bash
|
||||
while (( dry_run_i < ${#ENV_ARGS[@]} )); do
|
||||
printf ' %s %s %q \\\n' "${ENV_ARGS[$dry_run_i]}" "${ENV_ARGS[$((dry_run_i+1))]}" "${ENV_ARGS[$((dry_run_i+2))]}"
|
||||
(( dry_run_i += 3 ))
|
||||
done
|
||||
```
|
||||
|
||||
This assumes every element is a `--setenv NAME VALUE` triplet. If any future env arg uses a 2-element form (e.g. `--unsetenv NAME`, `--clearenv`), the loop will misalign and print mangled output or access out-of-bounds indices. The `BWRAP_ARGS` construction path handles variadic args correctly via array appending; the dry-run printer does not.
|
||||
|
||||
This is a latent fragility bug. It does not currently trigger because `ENV_ARGS` only contains `--setenv` triples, but it is a maintenance trap.
|
||||
|
||||
**Fix:** Build the dry-run ENV section by iterating the same conditional logic used to populate `ENV_ARGS`, or use a parallel dry-run-safe array instead of re-parsing `ENV_ARGS`:
|
||||
|
||||
```bash
|
||||
# Print each --setenv entry (stride-3 is safe only while all entries are --setenv)
|
||||
# Guard with an assertion:

### IN-01: Audit display reports credentials path as the symlink path, not the host path
|
||||
|
||||
**File:** `claudebox.sh:268`
|
||||
|
||||
**Issue:** The mounts section of `print_audit` displays:
|
||||
|
||||
```
|
||||
credentials $HOME/.claude/.credentials.json (read-write)
|
||||
```
|
||||
|
||||
`$HOME/.claude` on the host is the real Claude config directory (not a symlink), so the path shown is technically correct. However, once inside the sandbox `$HOME/.claude` becomes a symlink to `.claudebox`, making the display confusing when users compare the audit output with what they see on their host filesystem. Displaying the actual host source path (`$CREDS_FILE`) would be more accurate:
|
||||
|
||||
```bash
|
||||
printf ' %-12s %s (read-only)\n' "credentials" "$CREDS_FILE" >&2
|
||||
```
|
||||
|
||||
This also reflects the read-only fix from WR-01.

# 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 $HOME/.claudebox/.credentials.json when CREDS_MOUNT=true |
|
||||
|
||||
**Score:** 7/7 truths verified
|
||||
|
||||
### Required Artifacts
|
||||
|
||||
| Artifact | Expected | Status | Details |
|
||||
|----------|----------|--------|---------|
|
||||
| `claudebox.sh` | Credential mount logic, updated print_audit, updated --dry-run block | VERIFIED | File exists (383 lines), substantive, all three pieces present and wired into execution path; bash -n passes |
|
||||
|
||||
### Key Link Verification
|
||||
|
||||
| From | To | Via | Status | Details |
|
||||
|------|----|-----|--------|---------|
|
||||
| CREDS_MOUNT detection (lines 108-112) | BWRAP_ARGS conditional append (lines 370-371) | if [[ "$CREDS_MOUNT" == true ]] | WIRED | --bind used; read-write mount |
|
||||
| CREDS_MOUNT detection | dry-run display block (lines 337-338) | if [[ "$CREDS_MOUNT" == true ]] | WIRED | --bind mirrored correctly |
|
||||
| print_audit function | AUDIT_SANDBOX_KEYS / AUDIT_HOST_KEYS / AUDIT_EXTRA_KEYS arrays | [~]/[>]/[+] prefix loops (lines 242-259) | WIRED | Three loops reading from correct audit arrays |
|
||||
| CREDS_MOUNT | print_audit Mounts section (lines 268-270) | if [[ "$CREDS_MOUNT" == true ]] | 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.
