Summary

E2E test: add TESTING.md documenting how to run azlin tests.

Issue

Closes #915

Changes

● Read TESTING.md from main repo (shell)
│ cd /home/azureuser/src/azlin && cat TESTING.md
└ 171 lines...

● Check worktree git state (shell)
│ cd /home/azureuser/src/azlin/worktrees/feat/task-unnamed-1774842804 && git --no-pager status
│ --short && echo "---" && git --no-pager log --oneline -3
└ 8 lines...

Now I have the content. Let me check if TESTING.md is tracked in git at the current commit:

● Check if TESTING.md is tracked in git (shell)

└ 2 lines...

TESTING.md doesn't exist in git yet — it's only staged in the main repo. I'll create it in this worktree and commit.

● Create TESTING.md +171

Now verify and commit:

Step 16b: Outside-In Testing Results

Scenario 1 — Verify all documented file references exist

Method: Checked all 22 file/directory paths referenced in TESTING.md
Result: ✅ PASS — All 22 references resolve to existing files/directories
Details: rust/.cargo/config.toml correctly sets RUST_MIN_STACK=8388608, all integration test files exist, all linked docs exist, agentic scenario YAMLs present.

Scenario 2 — Run documented Quick Start command (cd rust && cargo test --all)

Method: Executed cargo test --all from the rust/ directory
Result: ✅ PASS — All tests pass (unit, integration, doc-tests across all 6 crates)
Output: test result: ok for all crate test suites; 0 failures

Scenario 3 — Verify test group counts are accurate

Method: Counted test group files in rust/crates/azlin/src/tests/ and handlers/tests/
Result: ✅ PASS (after fix) — Found 72 test groups (doc said 67), 13 handler test groups (correct)
Fix applied: Updated "67 test groups" → "72 test groups" in TESTING.md

Fix iterations: 1 (corrected test group count from 67 to 72)

Dependency Review

PR #916 is not a dependency update PR.

This PR was created by the repository owner (rysweet) and contains:

• TESTING.md — new documentation for running azlin tests
• Backup/DR commands — new Rust source files (cmd_backup.rs, cmd_backup_ops.rs, cmd_dr.rs) with 1,400+ lines of new implementation
• New test files — unit and integration tests for backup/DR functionality
• amplihack hooks — staged to .github/hooks/
• Project version bump — pyproject.toml: 2.7.0 → 2.8.0 (own project version, not a dependency)

No external dependency versions were changed in this PR. There is nothing to label or assess from a dependency management perspective.

If you have Dependabot PRs open for dependency updates, they would appear as separate PRs with titles like "Bump [package] from X to Y". Those would be the appropriate target for dependency review labeling and analysis.

Code Review — PR #916

Overall Assessment: Good — well-structured implementation with solid patterns.

User Requirements Check

Requirement	Status
TESTING.md at repo root	✅ Met
Backup & DR CLI commands	✅ Met
Name validation on handlers	⚠️ Partial (3 handlers missing)
No silent fallbacks	✅ Met
Tests pass	✅ 3,074 pass, 0 failures

Strengths

• Parallel operations via JoinSet (replicate-all, verify-all, dr test-all) — well done
• Positive allowlist in validate_name — correct approach
• DR cleanup surfaces warnings instead of silently discarding errors
• Config persistence distinguishes missing-file vs corrupt-file errors
• Consistent error handling — sanitize() on all stderr output, proper anyhow::bail!
• Good test coverage — unit tests for config serialization, tier logic, DR result contracts; integration tests for CLI arg validation

Issues Found

1. Missing validate_name in handle_backup_restore (cmd_backup_ops.rs:314)

   • Impact: Medium
   • Both vm_name and backup_name come from user CLI input and flow to az args without validation. The delegated handle_snapshot_restore in cmd_snapshot_ops.rs also has no validation.
   • Suggestion: Add validate_name(vm_name)? and validate_name(backup_name)? at the top of the function, before the confirmation prompt.

2. Missing validate_name in handle_backup_verify (cmd_backup_ops.rs:~345)

   • Impact: Medium
   • backup_name from user input goes directly to az snapshot show --name via verify_backup_core.
   • Suggestion: Add validate_name(backup_name)? in handle_backup_verify.

3. Missing validate_name in handle_backup_replicate (cmd_backup_ops.rs:454)

   • Impact: Medium
   • backup_name from user input goes to replicate_backup_core then az snapshot show/create without validation.
   • Suggestion: Add validate_name(backup_name)? in handle_backup_replicate.

4. Stale "TDD RED PHASE" comments in test files (Low)

   • test_group_backup_config.rs:1, test_group_dr_testing.rs:1, backup_dr_integration.rs:3
   • These files say "Tests FAIL until implementation" but all tests now pass. The module comments should be updated to reflect GREEN status.

5. Hardcoded default region "eastus2" in handle_dr_test_all (cmd_dr.rs:~225)

   • Impact: Low — acceptable for initial implementation
   • The default test_region is hardcoded. Consider reading from config or env in a future iteration.

Not Issues (Reviewed and Accepted)

• #[allow(unused_variables)] let _ = (verbose, output) — intentional scaffolding for future JSON/verbose output support, matches existing pattern in other cmd_*.rs files.
• AGENTS.md ~388-line deletion — auto-routing prompt content was moved, not lost.
• Test files defining their own types rather than importing from main code — valid contract-testing pattern.

Recommendations

• Fix issues 1-3 (missing validation) before merge — consistency with the security commit c60d7b2d that added validate_name everywhere else.
• Issue 4 (stale comments) is editorial — fix at convenience.

Philosophy Compliance

• Simplicity: 9/10 — clean, straightforward implementations
• Modularity: 9/10 — good separation (cmd_backup dispatches to cmd_backup_ops)
• Clarity: 9/10 — well-commented, obvious intent
• Security: 8/10 — almost complete validation, 3 handlers need it

Score: 8.5/10 — Solid work. Fix the 3 missing validation calls and this is ready to merge.

🔐 Security Review — PR #916 (Backup & DR Commands)

Reviewer: Security Agent | Scope: cmd_backup_ops.rs, cmd_dr.rs, cmd_backup.rs, cmd_snapshot_ops.rs, name_validation.rs

---

Overall Security Posture: 7/10 — Good foundation, 5 gaps to close

Strong baseline: all Command::new calls use parameterized args (no shell injection), all stderr is sanitized via azlin_core::sanitizer::sanitize(), and the positive-allowlist validate_name pattern is correct. However, it's applied inconsistently.

---

🔴 HIGH — Missing validate_name enables path traversal (2 handlers)

Affected: handle_backup_config_show (line 109), handle_backup_disable (line 151)

Both take vm_name from CLI input and pass it directly to backup_config_path() → backup_config_dir().join(format!("{}.toml", vm_name)). Without validate_name, a crafted vm_name like ../../etc/shadow produces:

~/.azlin/backup/../../etc/shadow.toml

• handle_backup_config_show → arbitrary file read (reads and displays TOML)
• handle_backup_disable → arbitrary file deletion (std::fs::remove_file)

Fix: Add validate_name(vm_name)? at the top of both handlers, matching the pattern used in handle_backup_configure (line 69).

---

🟠 MEDIUM — Missing validate_name on 3 handlers (inconsistent security boundary)

Affected:

1. handle_backup_restore (line 314) — vm_name and backup_name unvalidated
2. handle_backup_verify (line 371) — backup_name unvalidated
3. handle_backup_replicate (line 454) — backup_name and target_region unvalidated

These delegate to verify_backup_core, replicate_backup_core, or handle_snapshot_restore — none of which validate inputs. While Command::new with args prevents shell injection, the inconsistency means:

• Future refactors adding JMESPath interpolation won't know validation is missing
• replicate_backup_core constructs replica_name from backup_name + target_region and passes it as --name to az snapshot create
• Defense-in-depth principle requires validation at the handler boundary

Fix: Add validate_name on vm_name, backup_name, and target_region parameters in all 3 handlers.

---

🟠 MEDIUM — handle_snapshot_restore in cmd_snapshot_ops.rs lacks validation

Affected: handle_snapshot_restore — called by handle_backup_restore and potentially other code paths.

Takes vm_name and snapshot_name from callers without validation. Since it's a shared function (used by both backup and snapshot dispatch), it should validate its own inputs rather than relying on callers.

Fix: Add validate_name(vm_name)? and validate_name(snapshot_name)? at the top of handle_snapshot_restore.

---

🟡 LOW — No test coverage for injection/traversal attack vectors

No tests exercise path traversal (e.g., ../.. in names), JMESPath injection (e.g., '] || true || ['), or boundary characters. The validate_name function itself should have negative test cases for:

• Path traversal: ../etc/passwd
• JMESPath injection: vm'] | [0] || @.name == '
• Null bytes: vm\x00name
• Unicode confusables

Fix: Add security-focused unit tests in test_group_backup_config.rs or a dedicated test_name_validation.rs.

---

✅ Security Strengths (well done)

Control	Status
Shell injection prevention (Command::new with args)	✅ All 15+ call sites
Error message sanitization (sanitizer::sanitize)	✅ All 11 error paths
Positive-allowlist validation (validate_name)	✅ 11 of 16 entry points
Destructive operation confirmation (safe_confirm)	✅ restore, delete operations
No secrets/credentials in code	✅ Clean
No shell=true or string-interpolated commands	✅ Clean
DR cleanup error surfacing (not silent discard)	✅ Fixed in e87a23d

---

Summary of Required Fixes

Priority	Issue	Handler(s)	Fix
🔴 HIGH	Path traversal via backup_config_path	config_show, disable	Add validate_name(vm_name)?
🟠 MED	Missing validation (inconsistent boundary)	restore, verify, replicate	Add validate_name on all user params
🟠 MED	Shared function unprotected	handle_snapshot_restore	Add validate_name on both params
🟡 LOW	No negative security tests	test modules	Add injection/traversal test cases

Verdict: Fix the 2 HIGH issues before merge. The MEDIUM issues should be addressed in this PR since the security hardening commit (c60d7b2) explicitly established validate_name as the security boundary — leaving gaps undermines that commitment.

🧘 Philosophy Guardian Review: Backup & DR Module

Philosophy Score: B+

---

Strengths ✓

• Clean brick boundaries: cmd_backup.rs (dispatch), cmd_backup_ops.rs (operations), cmd_dr.rs (DR), name_validation.rs (shared validation) — each module has ONE clear responsibility
• Positive-allowlist validation: validate_name uses allowlist ([a-zA-Z0-9._-]) not blocklist — correct security posture
• Error visibility: load_backup_config distinguishes missing-file vs corrupt-config (no silent defaults). DR cleanup surfaces warnings instead of discarding
• Parallel ops via JoinSet: replicate_all, verify_all, test_all use tokio::task::spawn_blocking + JoinSet — straightforward concurrency without framework overhead
• Regeneratable design: Each handler follows validate → az CLI → parse → report pattern. AI could rebuild any handler from a one-line spec
• No unwrap() in production paths — all error paths use ?, bail!, or explicit matching

Concerns ⚠

1. cmd_backup_ops.rs at 855 lines / 19 functions — approaching the upper bound of a "brick." Not a violation yet, but watch for growth. If it crosses ~1000 lines, split into cmd_backup_ops.rs (CRUD) and cmd_backup_bulk.rs (replicate-all, verify-all, replication-jobs)
2. unwrap_or("-") for display fields (lines 279, 284, 288, 289, 595, 596, 601, 602, 679, 684, 685, 686) — these are Azure JSON response fields used only for table formatting. Acceptable for display defaults, but a defensive eprintln! when a required field like name is missing would surface API contract drift earlier
3. let _ = (verbose, output) in cmd_dr.rs:11 — suppressed unused params for future use. Acceptable short-term, but if verbose/output aren't wired within 1-2 PRs, remove them to avoid dead parameter accumulation

Forbidden Pattern Violations ✗✗

4. Missing validate_name on 5 handlers — inconsistent with the security hardening in commit c60d7b2d. These handlers accept user-supplied names that flow into file paths or az CLI args:

   Handler	Parameter	Risk
   handle_backup_config_show	vm_name	Path traversal via backup_config_path()
   handle_backup_disable	vm_name	Path traversal via backup_config_path()
   handle_backup_restore	vm_name, backup_name	Passed to handle_snapshot_restore
   handle_backup_verify	backup_name	Passed to az snapshot show --name
   handle_backup_replicate	backup_name	Passed to az snapshot show --name and used in format!() for replica name

   This is the single blocking issue. Every entry point that accepts a user-supplied name must validate it. No exceptions. The philosophy is: validate at the boundary, not deep inside.

Violations ✗

• None beyond the validate_name gap above.

---

Recommendations

1. Immediate (blocking): Add validate_name calls to all 5 handlers listed above. For handle_backup_restore, validate both vm_name and backup_name. This brings the module to 100% boundary validation
2. Structural (non-blocking): Monitor cmd_backup_ops.rs size — consider splitting at ~1000 lines
3. Simplification (non-blocking): The _core pattern (e.g., verify_backup_core, replicate_backup_core, dr_test_core) is clean and justified for JoinSet parallelism — keep it

Regeneration Assessment

Can AI rebuild this module?

• Specification clarity: Clear — each handler follows the same validate→execute→report pattern
• Contract definition: Well-defined — pub(crate) visibility, Result<()> returns, name validation at boundaries
• Verdict: Ready for AI regeneration (once validate_name gap is closed)

---

Summary: Solid implementation following brick philosophy. Clean module boundaries, good error visibility, no silent fallbacks in core logic. One blocking issue: 5 handlers missing validate_name — this is a forbidden-pattern violation (validation gap). Fix those and the philosophy score moves to A-.
