1. Executive Summary

This review covers the complete A-4 Phase 2 architectural refactor (commit b4821fa), the v2.0.0 skill version standardization (commit 7708d3a), and a follow-up usage text cleanup (resolve_session_id.sh, uncommitted). The refactor centralizes all agent-specific knowledge into a clean adapter pattern (BaseAgentAdapter + 4 concrete adapters) and completes Option B by removing all isolation.root consumers (C-3b).

Full 259/259 test suite passes (100%) — including all unit, component, contract, deployment, integration, and E2E tests. This is the first review to run the complete suite to completion (prior reviews were limited by the 30s tool timeout; this review used background execution for shell-heavy tests).

No lint, operability, or loss issues found. All orphan checks pass, all syntax checks pass, all adapter runtimes verified, facts bridge hardened with shlex.quote. Minor documentation inconsistencies in IMPROVEMENTS.md roadmap table noted as non-blocking observations.

Commit 7708d3a (8 SKILL.md files, +24/-8)

• All 8 SKILL.md: version: 2.0.0 ✅ (verified)
• delegate-job + orc-onboard: enhanced frontmatter (author, environments, metadata)

Uncommitted Working-Tree Change (resolve_session_id.sh, +1/-2)

• Usage text: removed outdated "isolation root" reference (2 lines → 1 line)
• This addresses the "minor observation #1" from prior review job 9cf96c56

---

3. Architecture Verification — Adapter Layer ✅

3.1 BaseAgentAdapter (base.py)

Abstract base class with complete interface:

• Properties: name, own_key, ready_tokens, exit_key, delegate_agent_key, identity_cache_fields (all NotImplementedError)
• Optional properties: input_prompt, input_placeholder, input_rule_pattern (default None)
• Methods: artifact_path(), verify_artifact(), purge_artifacts(), spawn_spec(), resume_spec(), auth_ok(), discover()
• Helpers: derive_session_name(), matches_session_name(), verify_session() (default impls)
• DiscoveryContext: workspace, agent_name, home_dir, claude_dir, epoch, row, mode + ws_key/cwd properties

3.2 All 4 Adapters Complete ✅ (Runtime Verified)

Adapter	spawn_spec	ready_tokens	exit_key	delegate_agent_key
claude	claude --dangerously-skip-permissions --session-id <uuid>	Anthropic|Assistant|Chat|Welcome	/exit	claude-code
agy	agy --dangerously-skip-permissions	Antigravity	Exit	antigravity-cli
cline	cline -i	Cline|history|Chat|...	/exit	cline-agent
hermes	hermes	Hermes	/exit	hermes-agent

All verified at runtime via get_adapter('<name>').spawn_spec(...) / .resume_spec(...) ✅

3.3 Facts Bridge Hardening ✅ (Eval-Safe)

• 8 MAM_* variables emitted with shlex.quote() ✅
• eval "$(python -m lib_py.agents facts claude)" under set -euo pipefail → rc=0 ✅
• test_facts_bridge_eval_contract PASSED ✅
• Orphan check: zero production refs to old AGENT_NAME=/OWN_KEY= names ✅

3.4 Circular Import Safety ✅

• base.py module-level import; verify_session.py function-level (lazy) import — no circular dependency ✅

---

4. Option B (C-3b) — Isolation Root Removal ✅

4.1 Removed Consumers

Consumer	Location	Status
mam_session_iso_root()	lib.sh	✅ Removed
iso_root branch	verify_session.py	✅ Removed
iso_root_of	workspace_uuid.py	✅ Removed
isolation validation	atomic_yaml.py	✅ Removed
Legacy purge block	stop_session.sh	✅ Replaced by adapter.purge_artifacts()
_iso_root/CLAUDE_ID_FLAG	resume_session.sh	✅ Replaced by adapter.resume_spec()

4.2 Orphan Checks ✅

• grep -rn 'mam_session_iso_root|iso_root_of|_iso_root' in production code → zero refs ✅
• grep -rn 'isolation' in atomic_yaml.py → zero refs ✅
• test_o11_isolation_root_respected removed from test_orc_onboard.py ✅
• lib.sh:1340 comment: documentation explaining removal ("were completely deprecated and removed") — not active code ✅

4.3 Tests Removed (consistency) ✅

• test_t11_legacy_isolation_row — tested isolation.root resolution (obsolete)
• test_comp_stop_safe_path_checking — tested isolation path guard (obsolete)
• orc_onboard test_o11_isolation_root_respected — tested iso_root respect (obsolete)

---

5. Shell Script Migration ✅

Script	Key Change	Fallback
create_session.sh	CMD_FULL from adapter.spawn_spec()	hardcoded case/esac ✅
resume_session.sh	CMD_FULL from adapter.resume_spec()	hardcoded case/esac ✅
reconcile.sh	_get_own_key() + adapter.spawn_spec()	—
stop_session.sh	adapter.exit_key + adapter.purge_artifacts()	—
lib.sh	wait_for_tui_ready uses MAM_READY_TOKENS	self-contained fallback ✅

All scripts have graceful degradation via hardcoded case/esac fallbacks ✅

---

6. resolve_session_id.sh Working-Tree Change ✅

The uncommitted change updates the usage text to remove the outdated "isolation root" reference:

- --session scopes resolution to that registry row — required for sessions
- created with --isolate (their conversation lives only in the row's isolation root).
+ --session scopes resolution to that specific registry row.

• bash -n syntax check: ✅ OK
• Zero remaining isolation references in the file ✅
• --session flag behavior unchanged (still calls find_workspace_uuid) ✅
• This is a correct documentation fix that aligns with the Option B removal

---

7. Syntax & Static Analysis ✅

File	Check	Result
resolve_session_id.sh	bash -n	✅ OK
lib.sh	bash -n	✅ OK
create_session.sh	bash -n	✅ OK
resume_session.sh	bash -n	✅ OK
stop_session.sh	bash -n	✅ OK
reconcile.sh	bash -n	✅ OK
lib_py/**/*.py	pytest collection	✅ 259 collected, 0 import errors

---

8. Full Test Verification — 259/259 PASS ✅

This review ran the complete test suite to completion for the first time (prior reviews were limited by the 30s tool timeout; this review used background execution for shell-heavy tests).

Suite	Tests	Time	Result
test_tier1_unit + test_a4_adapter_contract + test_orc_onboard + test_workspace_scope	77	12.78s	✅ PASS
test_deploy_freshness	9	12.48s	✅ PASS
test_b7 + test_b8 + test_o2 + test_o3	70	21.43s	✅ PASS
test_b4 + test_herdr_shim_contract + test_o1 + test_sanitize + test_sanity	41	18.76s	✅ PASS
test_uuid_target + test_tier2 + test_deploy_layout + test_deploy_registry_merge	52	167.87s	✅ PASS
test_tier3_integration + test_tier4_e2e	10	131.99s	✅ PASS
TOTAL	259	~365s	✅ 100% PASS

10. Documentation Review

10.1 Correctly Updated ✅

• IMPROVEMENTS.md:3 — 최종 갱신일 2026-08-16, P3-1/A-4 Phase 2 완료 ✅
• IMPROVEMENTS.md:5 — 미해결 6건 (arch 1, edge 4, orch 0, legacy 1) ✅
• IMPROVEMENTS.md:6 — 완료 19건 (A-4, C-3b added) ✅
• IMPROVEMENTS.md:22 — A-4 marked "✅ 완료 — P3-1" ✅
• IMPROVEMENTS.md:319 — C-3b marked "✅ 완료 — P3-1 / Option B" with full detail ✅
• LOG.md — P3-1 detailed entry ✅

10.2 Minor Inconsistencies (Non-Blocking) ⚠️

The planner's §8 explicitly instructed updating these, but b4821fa only partially addressed them. They are documentation-only and do not affect code correctness:

1. IMPROVEMENTS.md:107 — §4 header says "레거시 잔재 2건" but should be "1건" (C-3b completed; only C-6 remains). Header line 5 correctly says "1건".
2. IMPROVEMENTS.md:109-110 — C-3b still listed in §4 as "보류" (deferred) with old "되살린 코드" (revived code) description. Should be moved to §5 (completed). Line 319 already has the completion note, but §4 entry was not removed.
3. IMPROVEMENTS.md:117 — §5 header says "14건" but should reflect actual count (19 per line 6). This is a pre-existing inconsistency the planner noted in §8 item 9 — it was not fixed.
4. IMPROVEMENTS.md:252 — Roadmap P3-1 row says "진행 중" (in progress) but should be "✅ 완료". The planner's §8 item 10 explicitly asked to update lines 252-254.
5. IMPROVEMENTS.md:254 — Roadmap P3-3 (C-3b) row has no completion marker, but C-3b is completed.

These are non-blocking because: (a) the critical header lines and detail sections are correctly updated, (b) the roadmap table and §4/§5 sub-headers are stale summaries, not functional documentation, (c) they don't affect code correctness, test results, or runtime behavior.

---

11. Lint / Operability / Loss Analysis

11.1 Lint ✅

• All 6 shell scripts pass bash -n ✅
• All Python modules collect without import errors ✅
• No shellcheck available (macOS) — static analysis limited to bash -n
• No flake8 run (not in venv), but test_o36_bash_syntax_clean PASSED ✅

11.2 Operability ✅

• All 4 adapter runtimes produce correct spawn/resume commands ✅
• Facts bridge eval-safe under set -euo pipefail ✅
• Shell scripts have hardcoded case/esac fallbacks for adapter failures ✅
• lib.sh:1340 documentation comment correctly explains the Option B removal ✅
• resolve_session_id.sh still correctly delegates to find_workspace_uuid ✅

11.3 Loss ✅

• Zero production-code references to removed symbols (mam_session_iso_root, iso_root_of, _iso_root) ✅
• Zero isolation references in atomic_yaml.py ✅
• Removed tests (test_t11, test_o11, test_comp_stop_safe) are obsolete (tested removed behavior) ✅
• New test_a4_adapter_contract.py (9 tests) pins the new adapter contract ✅
• No functional regression (259/259 PASS) ✅

---

12. Minor Observations (Non-Blocking)

1. IMPROVEMENTS.md roadmap/section headers stale (§10.2 above) — 5 documentation inconsistencies. Non-blocking; the critical content (header lines 3/5/6, detail at lines 22/319) is correct. Recommend a follow-up doc-sync commit to update §4 header (107), remove C-3b from §4 (109-110), update §5 header count (117), and mark P3-1/P3-3 as completed in roadmap (252/254).

2. resolve_session_id.sh change uncommitted — the working-tree change is a correct cleanup but has not been committed yet. Recommend committing it as a follow-up to close the loop on the "minor observation #1" from job 9cf96c56.

3. hermes adapter untested at runtime — hermes is not installed on this machine; auth_ok/discover paths cannot be physically verified. However, the adapter contract tests (test_h1_to_h8, test_h9_h10) validate the interface. This is a known limitation documented in the planner's §9.1.

---

13. Limitations

• macOS only: pytest-xdist not installed; tests run serially. Linux/CI environment not verified.
• shellcheck not available: static shell analysis limited to bash -n.
• flake8 not run: not in venv; relied on test_o36_bash_syntax_clean for bash and pytest collection for Python import validation.
• hermes uninstalled: physical verification of hermes adapter runtime paths not possible.
• Background test execution: shell-heavy tests (52+10=62 tests) ran in background over ~5 minutes; output captured from /tmp/pytest_heavy.log and /tmp/pytest_tier34.log.

---

14. Conclusion

The A-4 Phase 2 refactor is a clean, well-structured architectural migration that:

1. Centralizes all agent-specific knowledge into a clean adapter pattern (4 concrete adapters + abstract base)
2. Completes Option B (C-3b) by removing all isolation.root consumers
3. Hardens the facts bridge with shlex.quote for eval safety
4. Standardizes all 8 SKILL.md files to v2.0.0
5. Adds 9 new contract tests pinning the adapter interface

All 259 tests pass (100%) — unit, component, contract, deployment, integration, and E2E. No lint, operability, or loss issues found. The only findings are minor documentation inconsistencies in IMPROVEMENTS.md roadmap table (non-blocking) and the resolve_session_id.sh change being uncommitted (a correct fix pending commit).

The implementation does not require design changes or replanning. The minor documentation gaps are fixable with a simple doc-sync commit.

[VERDICT: PASS]
