+# Phase 8: Rust Directory Archiver Verification Report
+
+**Phase Goal:** `pack` accepts directories and recursively archives them with full path hierarchy and permissions; `unpack` restores the complete directory tree
+**Verified:** 2026-02-26T19:10:00Z
+**Status:** passed
+**Re-verification:** No -- initial verification
+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | pack accepts a directory argument and recursively includes all files and subdirectories with relative paths | VERIFIED | `collect_entries()` dispatches to `collect_directory_entries()` which uses `fs::read_dir()` with DFS preorder recursion (archive.rs:150-194); test `test_roundtrip_directory` verifies files at `testdir/subdir/nested.txt` |
+| 2 | pack handles mixed file and directory arguments in a single invocation | VERIFIED | `collect_entries()` (archive.rs:200-240) iterates all inputs and handles both `is_dir()` branches; test `test_roundtrip_mixed_files_and_dirs` packs standalone.txt + mydir/ and verifies both |
+| 3 | Empty directories are stored as TOC entries with entry_type=0x01 and zero-length crypto fields | VERIFIED | `make_directory_entry()` (archive.rs:128-144) sets entry_type=1, all sizes=0, zeroed iv/hmac/sha256; test verifies `testdir/empty` is recreated as a directory |
+| 4 | unpack creates the full directory hierarchy and restores Unix mode bits on files and directories | VERIFIED | `unpack()` handles directories at archive.rs:497-506 with `create_dir_all` + `set_permissions(from_mode())`, files at 564-570; test checks nested.txt=0o755, empty dir=0o700 |
+| 5 | inspect shows entry type (file/dir), relative paths, and octal permissions for each TOC entry | VERIFIED | `inspect()` prints type_str and perms_str at archive.rs:419-422; test `test_inspect_shows_directory_info` asserts stdout contains "dir", "file", permissions, and "Permissions:" |
+
+**Score:** 5/5 truths verified
+
+### Required Artifacts
+
+| Artifact | Expected | Status | Details |
+|----------|----------|--------|---------|
+| `src/format.rs` | v1.1 TocEntry with entry_type and permissions fields, VERSION=2, entry_size=104+name_length | VERIFIED | TocEntry has `entry_type: u8` (line 31), `permissions: u16` (line 32); VERSION=2 (line 7); entry_size returns 104+name.len() (line 328-329); write/read functions serialize both new fields |
+| `src/archive.rs` | Recursive directory traversal in pack, directory handling in unpack with chmod, updated inspect | VERIFIED | `collect_directory_entries()` with DFS preorder (line 150); `set_permissions(from_mode())` for dirs (line 500) and files (line 567); inspect prints type/perms (line 419-422); 587 lines total |
+| `src/cli.rs` | Updated doc comments for directory support | VERIFIED | Pack doc: "Pack files and directories into an encrypted archive" (line 14); files doc: "Input files and directories to archive" (line 16) |
+| `tests/round_trip.rs` | Directory round-trip integration test | VERIFIED | 3 new tests: `test_roundtrip_directory` (line 198), `test_roundtrip_mixed_files_and_dirs` (line 263), `test_inspect_shows_directory_info` (line 305); all 9 integration tests pass |
+
+### Key Link Verification
+
+| From | To | Via | Status | Details |
+|------|----|-----|--------|---------|
+| src/archive.rs | src/format.rs | TocEntry with entry_type/permissions fields | WIRED | archive.rs constructs TocEntry with both entry_type (lines 277, 322) and permissions (lines 278, 323) from ProcessedFile |
+| src/archive.rs | std::os::unix::fs::PermissionsExt | Unix mode bit restoration | WIRED | `use std::os::unix::fs::PermissionsExt` (line 6); `set_permissions` + `from_mode` used at lines 500-502 (dirs) and 567-569 (files) |
+| src/archive.rs | std::fs::read_dir | Recursive directory traversal | WIRED | `fs::read_dir(dir_path)` at line 163 within `collect_directory_entries()` function |
+
+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|------------|-------------|--------|----------|
+| DIR-01 | 08-01-PLAN | pack recursively traverses directories and adds all files | SATISFIED | `collect_directory_entries()` recursion with `read_dir`; test `test_roundtrip_directory` |
+| DIR-02 | 08-01-PLAN | Relative paths preserved during archival (dir/subdir/file.txt) | SATISFIED | Path construction as `base_name/child_name` in `collect_directory_entries()` (line 169-173); test verifies `testdir/subdir/nested.txt` |
+| DIR-03 | 08-01-PLAN | Empty directories stored as "directory" type TOC entries | SATISFIED | `make_directory_entry()` with entry_type=1, zero crypto; test verifies `testdir/empty` is recreated |
+| DIR-04 | 08-01-PLAN | unpack creates full directory hierarchy | SATISFIED | `create_dir_all()` for directory entries (line 499) and parent dirs for files (line 513); test confirms nested structure |
+| DIR-05 | 08-01-PLAN | unpack restores Unix mode bits for files and directories | SATISFIED | `set_permissions(from_mode(entry.permissions))` for dirs (line 500-502) and files (line 567-569); test checks 0o755 and 0o700 |
+
+No orphaned requirements found -- REQUIREMENTS.md maps exactly DIR-01 through DIR-05 to Phase 8.
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| src/archive.rs | 272, 282 | "placeholder" comment on data_offset=0 | Info | Intentional two-pass algorithm -- offset is overwritten at line 327. Not a stub. |
+
+No blockers or warnings found.
+
+### Human Verification Required
+
+### 1. Smoke Test with Real Directory Tree
+
+**Test:** Create a multi-level directory tree with mixed content, pack it, inspect, and unpack
+```
+mkdir -p /tmp/test/sub/deep && echo "hello" > /tmp/test/file.txt && echo "nested" > /tmp/test/sub/deep/file.txt && mkdir /tmp/test/empty
+cargo run -- pack /tmp/test -o /tmp/test.aea
+cargo run -- inspect /tmp/test.aea
+cargo run -- unpack /tmp/test.aea -o /tmp/out
+ls -laR /tmp/out/test/
+```
+**Expected:** All files extracted with correct content, empty directory exists, permissions match originals
+**Why human:** Visual confirmation of output format and real filesystem behavior
+
+### 2. Permission Preservation on Specific Modes
+
+**Test:** Create files with unusual permissions (0o700, 0o600, 0o555), pack and unpack
+**Expected:** Exact permission bits preserved after round-trip
+**Why human:** Edge case permission handling may differ across filesystems
+
+### Test Suite Results
+
+All 41 tests pass (25 unit + 7 golden + 9 integration):
+- 25 library unit tests: format, crypto, compression modules
+- 7 golden test vectors: known-answer crypto tests
+- 9 integration tests: 6 existing + 3 new directory tests
+
+### Commit Verification
+
+All 3 task commits verified in git history:
+- `4e25d19` feat(08-01): update format.rs for v1.1 TOC entry layout
+- `7820c18` feat(08-01): add directory support to pack/unpack/inspect
+- `8760981` test(08-01): add directory round-trip integration tests
