f8335e4515 feat(my-deepagent): v0.3 PR #1 — interactive session persistence + LangGraph saver wiring 
v0.3의 토대. REPL/GUI 둘 다 장기 대화를 영속해서 `mydeepagent --session <id>`
또는 `GET /api/sessions/{id}`로 어디서든 이어 진행 가능. Claude Code의
`claude --resume` 등가 능력.

Data model
- `persistence/models.py`:
  - 신규 `MessageRow` 테이블 — (session_id, seq) UNIQUE, role/content/
    tool_calls/token_count/is_summary/archived/ts. LangGraph checkpoint =
    source of truth, 이 테이블은 GUI/CLI 빠른 조회 mirror. divergence
    rebuild 매커니즘 없음 (단순성 우선).
  - `InteractiveSessionRow` 컬럼 8개 추가:
      total_input_tokens, total_output_tokens (PR #2 tiktoken으로 정밀화 예정),
      model, project_key (sha256(realpath(repo_path))[:16]),
      title (첫 user msg 50자), plan_mode (PR #5), parent_session_id (PR #6),
      depth (PR #6 sub-agent depth ≤ 3).
- `alembic/versions/684e70f4536a_*.py` (신규):
  - `op.batch_alter_table` 사용 — SQLite ALTER constraint 미지원 우회. Postgres는
    native DDL.
  - 자동생성이 제안한 LangGraph 테이블 (`checkpoints` 등) drop 라인은 의도적으로
    제거 (langgraph-checkpoint-postgres가 자체 관리).
  - server_default 박아서 기존 row 안전.

CLI
- `cli/interactive.py`:
  - REPL 진입 시 `get_checkpointer_ctx(config.database_url)` 컨텍스트 열고
    REPL 전체 동안 유지. `build_agent(..., checkpointer=saver)`로 deepagents에
    LangGraph saver wire. v0.2 PR #10의 CostMiddleware / AuditToolMiddleware
    보존.
  - `_invoke_and_stream`이 ainvoke 전후 명시적 MessageRow insert
    (user → ainvoke → assistant). last_message_at + total_*_tokens 누적 +
    첫 user msg로 title 자동 setter.
  - `InteractiveSession.thread_suffix` 도입. /model / /agent / /clear 호출
    시 suffix bump → LangGraph thread_id = `{session_id}:{suffix}` 로 새
    deepagents 컨텍스트 시작 (compaction과 같은 패턴, PR #2 재사용).
  - 신규 `--session <id|prefix>` 옵션: 기존 row 로드 (ended이면 거부) 또는
    신규 row insert (AgentPersonaRow upsert + project_key 박음).
  - `/clear` 슬래시 갱신: messages.archived=True + 새 thread 시작. 세션 자체
    는 살아있음 — `sessions show <id> --all`로 조회 가능.
- `cli/sessions.py` (신규): `mydeepagent sessions list/show/resume/end`.
  show <id> [--all]이 archived 메시지까지. 6+ char prefix + 중복 시 명시
  에러.
- `cli/main.py`: --session 옵션 + sessions 서브명령 + interactive_command
  시그니처 확장.

HTTP API
- `api/models.py`: SessionSummary / MessageInfo / SessionDetail /
  CreateSessionRequest / PostMessageRequest / SessionAck DTO 신규 (모두
  extra="forbid").
- `api/routes/sessions.py` (신규):
    GET  /api/sessions?limit=&state=
    GET  /api/sessions/{id}?all=true     (마지막 200 메시지)
    POST /api/sessions                    (persona_name, model_override, repo_path)
    POST /api/sessions/{id}/messages      (사용자 메시지 append, 동기 persist;
                                            PR #7 GUI에서 background ainvoke 추가)
    GET  /api/sessions/{id}/stream        (SSE — 0.5s polling, last-event-id 헤더
                                            + ?last_seq 둘 다 지원)
    POST /api/sessions/{id}/end
- `api/app.py`: sessions 라우터 마운트.

Tests
- `tests/integration/test_session_persist.py` (5 시나리오):
    1. create + post → row + 메시지 + title + token 누적 영속
    2. list가 신규 3 세션 모두 포함
    3. prefix resolution + 404
    4. end 후 메시지 거부 (409)
    5. ?all=true가 archived 메시지 surfacing

e21a5241bf feat(my-deepagent): v0.2 PR #1 — Postgres migration (ahead of M8-Py FastAPI) 
Switches the production backing store from SQLite to PostgreSQL 16, per DR-2.
The migration trigger is two concurrent writers on the my-deepagent ORM
tables — which first appears with FastAPI (M8-Py). Doing the cut now keeps
the surface area small while M8-Py is still planning.

Production deps: `asyncpg`, `psycopg[binary]`, `langgraph-checkpoint-postgres`.
Test deps: `aiosqlite` (the bulk of unit + integration tests stay on sqlite
tmp_path for speed; the E2E suite and the new checkpointer tests exercise
the live Postgres path).

Highlights
- `persistence/db.py`: dialect-aware connect listener. SQLite still gets
  WAL + busy_timeout=5000 + foreign_keys=ON; Postgres gets `SET TIME ZONE 'UTC'`.
  Added `Database.dialect_name` + `drop_schema` (test-only).
- `persistence/checkpointer.py`: SqliteSaver → AsyncPostgresSaver. API is
  now async (`async with`) and takes a connection string. SQLAlchemy URL
  prefixes (`+asyncpg`, `+psycopg`) are auto-stripped to a plain libpq DSN
  (`_to_psycopg_dsn` helper, 4 unit tests).
- `persistence/upsert.py` (new): `insert_for(session)` — dialect-aware UPSERT
  helper. Picks `postgresql.insert` or `sqlite.insert` based on the bound
  engine. Replaces 5 hardcoded `sqlite_insert` call sites in `budget.py`,
  `recovery.py`, `cli/doctor.py`.
- `persistence/models.py`: `RunRow` partial unique index declares both
  `postgresql_where=` and `sqlite_where=` for cross-dialect correctness.
- `config.py`: default `database_url` now
  `postgresql+asyncpg://devflow:devflow@localhost:55432/mydeepagent`. v3
  `devflow` DB preserved untouched; v4 lives in a fresh `mydeepagent` DB.
- `cli/doctor.py` check 8: dialect-aware DB liveness probe. Postgres path
  runs `SELECT 1` (pg_isready equivalent); SQLite keeps `PRAGMA integrity_check`.
- `alembic/env.py`: env-aware URL resolution (`MYDEEPAGENT_DATABASE_URL` >
  `DATABASE_URL` > default). Async driver prefixes are mapped to the sync
  equivalents alembic needs.
- `alembic/versions/9f2a6c79667e_v0_2_baseline_schema_postgres.py` (new):
  fresh baseline autogenerated against live Postgres. Old SQLite migrations
  (`79945fdc2649`, `839f2233e346`) deleted — v0.2 starts a clean history.
- `tests/conftest.py` (new): `pg_db_url` async fixture creates a fresh DB
  per test against docker-compose `devflow-postgres` and drops it on
  teardown after terminating lingering backends.
- `tests/integration/test_checkpointer.py`: rewritten for AsyncPostgresSaver
  (4 pure DSN-converter unit tests + 3 async context-manager integration tests).
- `tests/integration/test_e2e_workflow.py`: switched to `pg_db_url`. Real
  OpenRouter E2E now exercises the production Postgres path end-to-end.

Recovery
- Previous SQLite database at the platformdirs data_dir is NOT auto-migrated;
  v0.1.0 was the only release that wrote to it. Set
  `MYDEEPAGENT_DATABASE_URL=sqlite+aiosqlite:///<path>` to read it.
- The v3 `devflow` Postgres DB is preserved untouched (separate database
  name); to inspect: `psql -h localhost -p 55432 -U devflow -d devflow`.

Gates
- ruff check + ruff format --check + mypy --strict: PASS (102 source files)
- pytest non-E2E: 576 PASS (5.46 s)
- pytest E2E real OpenRouter on Postgres: 1 PASS (122.93 s, ~$0.05/run)

--no-verify: lefthook still TS-only (deleted in 0e61b2d but still queryable
in git history).

17ba5d723b feat(my-deepagent): v0.1.0 Step 0~5 — scaffolding through deepagent + OpenRouter 
Python rewrite of the agent harness on top of deepagents 0.6.1 + langchain 1.x,
replacing the abandoned TS attempt in packages/. 388 unit/integration tests pass.

Steps
-----
0. Scaffolding — uv workspace, ruff/mypy/pre-commit/alembic, src/tests/docs
   trees with docs/schemas/ seeded from my-deepagent-seed/.
1. Core — config (pydantic-settings with MYDEEPAGENT_ env prefix and TOML
   source), enums (Backend, Capability, RiskLevel, ApprovalDecisionAction,
   ApprovalState, RunState, RunPhaseState, SessionState, ErrorClass),
   errors (MyDeepAgentError + BudgetExhaustedError with PEP-3134 cause +
   context suppression), hash (canonical JSON + sha256).
2. Persona/Workflow/Binding — pydantic v2 schemas with tuple-based deep
   immutability (post-construction hash drift prevented), YAML loaders,
   deterministic auto-select (preferred_backends → version → name → hash),
   override resolution with ineligibility diagnostics, PersonaConsentStore
   with fcntl.flock + tmp+fsync+rename atomic write.
3. Artifact schema registry — Draft202012Validator, multi-root resolution,
   structured ValidationFinding output.
4. Persistence — 18 SQLAlchemy 2.0 async ORM models with FK CASCADE/RESTRICT,
   WAL + busy_timeout + foreign_keys PRAGMA, alembic baseline +
   ux_active_run_repo_base partial unique index, LangGraph SqliteSaver as
   context manager only (lifecycle safety).
5. DeepAgent session — build_agent wires Persona → create_deep_agent with
   LocalShellBackend / FilesystemBackend / StateBackend / CompositeBackend,
   ChatOpenAI(base_url=openrouter) for openrouter: model strings, and 4
   middleware classes (cost / audit-tool / safety-shell / fallback-model).

Critical workarounds
--------------------
- deepagents 0.6.1 rejects FilesystemPermission together with backends that
  implement SandboxBackendProtocol (LocalShellBackend). SafetyShellMiddleware
  enforces destructive-command and secret-path policy at the tool layer
  instead, and build_agent strips the permissions kwarg when the persona's
  deepagents_backend is local_shell.
- FilesystemOperation in deepagents is Literal['read', 'write'] only;
  _map_operations collapses our richer schema (read/write/edit/ls) safely.

Real OpenRouter smoke
---------------------
test_openrouter_deepagents_local_shell_smoke calls DeepSeek via deepagents +
LocalShellBackend + SafetyShellMiddleware end-to-end. PASS, ~$0.000001 cost,
input=9 / output=1 tokens with content "OK".
