# Dependency graph
|
|
requires:
|
|
- phase: 05-shell-decoder
|
|
plan: 01
|
|
provides: "shell/decode.sh -- busybox-compatible POSIX shell decoder"
|
|
- phase: 02-core-archiver
|
|
provides: "Rust archiver CLI for creating test archives"
|
|
provides:
|
|
- "shell/test_decoder.sh -- cross-validation test script (6 tests, Rust pack -> Shell decode -> SHA-256 verify)"
|
|
- "Validated shell decoder correctness across all edge cases: text, binary, no-compress, empty, large, Cyrillic filenames"
|
|
affects: [06-obfuscation]

# Phase 5 Plan 2: Shell Decoder Cross-Validation Tests Summary
|
|
|
|
**Cross-validation test script with 6 test cases (single file, multiple files, no-compress, empty, large 100KB, Cyrillic filename) all passing on first run via Rust pack -> sh decode.sh -> SHA-256 verify**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-02-24T22:42:47Z
|
|
- **Completed:** 2026-02-24T22:44:38Z
|
|
- **Tasks:** 2
|
|
- **Files created:** 1
|
|
|
|
## Accomplishments
|
|
- Created comprehensive cross-validation test script (275 lines) following kotlin/test_decoder.sh pattern
|
|
- All 6 test cases passed on first run with zero decode.sh fixes needed
|
|
- Validated SHL-01 (single text file), SHL-02 (no-compress mode), and SHL-03 (Cyrillic UTF-8 filename)
|
|
- Verified shell decoder produces byte-identical output to originals via SHA-256 comparison
|
|
- Confirmed existing Rust test suite (6 tests) still passes -- no regressions
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create shell/test_decoder.sh cross-validation test script** - `e9d7442` (test)
|
|
2. **Task 2: Run cross-validation tests and fix any decode.sh issues** - no commit (all tests passed, no fixes needed)
|
|
|
|
## Files Created/Modified
|
|
- `shell/test_decoder.sh` - Cross-validation test script: 6 test cases covering all edge cases for shell decoder
|
|
|
|
## Decisions Made
|
|
- All 6 tests passed on first run -- decode.sh implementation from Plan 1 was correct
|
|
- Used `sh "$DECODER"` (not `bash`) to invoke decode.sh, ensuring POSIX sh compatibility is tested
|
|
- Followed kotlin/test_decoder.sh pattern exactly for consistency across decoder test suites
|
|
- 7 total assertions across 6 tests (Test 2 verifies both text.txt and binary.bin)
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None.
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Shell decoder fully validated with cross-validation tests
|
|
- Phase 5 (Shell Decoder) is complete: both decode script and test suite done
|
|
- Phase 6 (Obfuscation) can extend decode.sh with XOR header deobfuscation and encrypted TOC parsing
|
|
- Test script can serve as regression test when obfuscation layer is added
