feat(telegram): bot bonuri fiscale — OCR → preview → Oracle write

- US-001: mută queue_client.py în data_entry/services/ocr/
- US-002/003/004: oracle_receipt_writer + oracle_server_id în DB
- US-005: receipt_handlers.py (PDF/photo/callback flow)
- US-006: wire handlers în main.py, per-schema connect, seq_cod.nextval
- US-007: .gitignore secrets/*.oracle_pass
- US-008/009/010: teste unit + integration + E2E
- setup-secrets.sh helper + template
- docs/telegram/README.md actualizat cu arhitectura nouă

Testat E2E pe DB live (MARIUSM_AUTO). COD din seq_cod.nextval.
pypdfium2 fallback pentru PDF decode (fără poppler).

+
+Running plan-eng-review on the design doc. CEO review just completed — now focusing on what eng review uniquely covers: code patterns, test coverage diagram, performance specifics, and parallelization.
+

+
+## /plan-eng-review — Telegram Bonuri Fiscale
+
+Design doc: `~/.gstack/projects/romfast-echo-core/moltbot-master-design-20260504-221523.md`. Reviewed by /office-hours (8/10), /plan-ceo-review just completed (5 findings folded back into plan).
+
+---
+
+### Step 0 — Scope Challenge
+
+**Existing code already solves:**
+
+| Sub-problem | Existing | Plan reuses? |
+|---|---|---|
+| OCR async queue submit + poll | `backend/scripts/whatsapp_import/ocr_client.py` | YES (direct import) ✅ |
+| Oracle write via PACK_CONTAFIN | `backend/scripts/whatsapp_import/process_v2.py:60-135` | Adapts pattern (not import) ✅ |
+| Telegram auth check | `backend/modules/telegram/auth/linking.py::get_user_auth_data` | YES ✅ |
+| File download from Telegram | `python-telegram-bot::Bot.get_file().download_to_drive()` | YES ✅ |
+| Date parse / nul-safe field handling | `process_v2.py:64-67` (date), `process_v2.py:84-87` (nrract) | Plan must replicate, NOT importable as-is |
+| CUI → cont mapping | `process_v2.py::get_cont_cheltuiala` (hardcoded Romfast) | Adapted with warning fallback |
+
+**Rebuilding:** `_save_to_oracle` is being adapted from `process_v2.py`, not imported. Reason: `process_v2.py` is a CLI script that reads from a `result` object with `.attribute` access. Telegram handler will receive a `dict`. Different shape, can't import. **The Oracle write logic should be extracted to a shared helper** — `backend/modules/data_entry/services/oracle_receipt_writer.py` — so the next channel (WhatsApp, email) doesn't trigger a third copy. See Architecture finding #1.
+
+**Minimum set of changes** — design doc proposes 5 file touches. Eng-review verdict: 5 is the minimum.
+
+**Complexity check** — 5 files. Under threshold. No new classes (flat functions per existing pattern). Clean.
+
+**Search check (Layer 1/2/3):**
+- python-telegram-bot async file download → built-in `bot.get_file().download_to_drive()`. Plan uses it. ✅ [Layer 1]
+- `concurrent_updates=True` for parallel users → built-in flag in `Application.builder()`. Plan should set it (CEO finding FINDING-ARCH-1). [Layer 1]
+- Async wrapper for sync DB driver → `asyncio.to_thread()` (Python 3.9+). Plan uses it. ✅ [Layer 1]
+- Per-user state → `context.user_data` (PTB built-in). Plan uses it. ✅ [Layer 1]
+
+No reinvention. No L2/L3 patterns introduced.
+
+**TODOS cross-reference:** No `TODOS.md` exists in roa2web. Recommend adding one as part of this PR with the deferred items from the CEO review (server_id DB persistence, "view in ERP" link, unify-via-receipt-service).
+
+**Distribution check:** No new artifact. Code lives inside the existing roa2web bot process. N/A.
+
+**Step 0 verdict:** Scope is right. Proceed to sections.

+       ⚠ hardcoded path        cred: secrets/<server_id>_write.oracle_pass
+```
+
+**FINDING-ARCH-1** `[P2] (confidence: 8/10)` `_save_to_oracle` duplication risk. The plan adapts `process_v2.py`'s PACK_CONTAFIN logic into `receipt_handlers.py::_save_to_oracle`. This makes 2 copies of the 3-step Oracle write. WhatsApp adapter is the third channel waiting to land — that becomes 3 copies. DRY violation.
+
+Recommendation: extract to `backend/modules/data_entry/services/oracle_receipt_writer.py::write_receipt(receipt_dict, oracle_cfg) -> tuple[int, str]`. Both `process_v2.py` and `receipt_handlers.py` import it. Effort: ~20 min (CC) for the extraction + adapt both callers.
+
+This connects to engineering preference: "DRY is important — flag repetition aggressively."
+
+**FINDING-ARCH-2** `[P3] (confidence: 9/10)` `bot/__init__.py` import boundary. The plan imports from `backend.scripts.whatsapp_import.ocr_client`. Importing from `scripts/` into `modules/` is backwards — scripts should depend on modules, not the reverse.
+
+Recommendation: move `ocr_client.py` to `backend/modules/data_entry/services/ocr/queue_client.py`. The whatsapp scripts then import FROM modules. Then receipt_handlers imports from a proper module path. Bonus: solves the hardcoded `/workspace/roa2web/...` path natively, since the path becomes relative to `Path(__file__).parents[3]` from inside the modules tree.
+
+Effort: ~15 min (CC) for the move + 3 import updates.
+
+**FINDING-ARCH-3** `[P1] (confidence: 9/10)` Already in CEO review as FINDING-ARCH-1: `concurrent_updates=False` default. One-line fix: `Application.builder().token(T).concurrent_updates(True).build()`. Without it, the 120s OCR poll blocks every other user. Critical for any team with ≥2 active users.
+
+**Production failure scenarios:**
+
+| Scenario | Plan accounts for? |
+|---|---|
+| OCR worker process down | ✗ — plan polls until 120s timeout, generic error. Should health-check first. |
+| Oracle DB unreachable | ✓ — `try/except` around `_save_to_oracle` + `finally` cleanup |
+| Telegram file download fails (40MB+) | ✗ — no try/except around `download_to_drive()` |
+| User auth revoked between submit and confirm | ✗ — no re-check at confirm time |
+| Bot restart between submit and confirm | ✓ — pending lost (in-memory), pending file orphaned, startup cleanup scan handles it |
+| `secrets/` file missing | Partial — returns empty password, ORA-01017, generic error |
+
+**Coupling concerns:** `receipt_handlers` → `whatsapp_import` (BACKWARDS). FINDING-ARCH-2 fixes it.
+
+**Scaling:** OCR poll dominates. With concurrent_updates=True (FINDING-ARCH-3), 10 simultaneous users × 120s each is bounded by the OCR worker throughput, not handler concurrency. Worker is `data_entry/services/ocr/job_worker.py` — single worker, queue-based — so OCR is the real serialization point. Acceptable for a 4-accountant team.
+
+**SPOF:** OCR worker. Documented above.
+
+**Rollback:** `git revert + restart`. If cherry-pick #3 (server_id DB column) is implemented, additive nullable column → safe rollback.
+
+**STOP** — 3 architecture findings. Going with recommendations: ACCEPT all three.
+
+---
+
+### Section 2 — Code Quality Review
+
+**FINDING-CQ-1** `[P2] (confidence: 8/10)` `_format_receipt_preview` will be a string concat for ~10 fields with None handling. The plan describes it as 1 function returning 1 multi-line string. With the cherry-pick #1 (low-confidence warning) added, this function does 2 things: format + warn.
+
+Recommendation: split into `_format_receipt_preview(ocr_result)` and `_confidence_warning(confidence)` returning `Optional[str]`. Compose them in the caller. Keeps each function under 10 lines, testable in isolation.
+
+Effort: trivial. Maps to preference: "explicit over clever."
+
+**FINDING-CQ-2** `[P2] (confidence: 9/10)` Magic numbers in plan: `120` (OCR timeout seconds), `0.3` (poll interval), `600` (TTL seconds), `0.60` (low-confidence threshold). Spread across the file as hardcoded literals.
+
+Recommendation: top of `receipt_handlers.py`:
+```python
+OCR_TIMEOUT_S = 120
+OCR_POLL_INTERVAL_S = 0.3
+PENDING_TTL_S = 600
+LOW_CONFIDENCE_THRESHOLD = 0.60
+TEMP_FILE_PREFIX = "receipt_"
+```
+
+Effort: 5 min. Maps to preference: "bias toward explicit."
+
+**FINDING-CQ-3** `[P2] (confidence: 8/10)` Error handling in plan uses `except Exception as e` (line 172 of design doc). This is the catch-all anti-pattern flagged in the skill's prime directives.
+
+Recommendation: catch the specific exceptions:
+```python
+except oracledb.DatabaseError as e:
+    msg = _format_oracle_error(e)  # CEO finding FINDING-ERR-3
+    await query.edit_message_text(f"❌ Eroare bază de date: {msg}")
+    logger.exception("receipt: oracle_write_failed user=%s", oracle_username)
+except (asyncio.TimeoutError, OSError) as e:
+    await query.edit_message_text(f"❌ Eroare sistem: {e}")
+    logger.exception("receipt: system_error")
+```
+
+Don't catch `Exception` — let unexpected ones crash the handler so PTB's error_handler logs them with full traceback. This is how `bot_main.py:148` already does it (`add_error_handler(error_handler)`).
+
+**FINDING-CQ-4** `[P3] (confidence: 7/10)` `pending_receipt` dict is structural — created in 1 place, consumed in 1 place. With 6 keys including a TTL field, this is on the edge of needing a `dataclass`. Going with explicit dict for now is fine (matches existing handlers.py style, avoids new abstraction). Flag: if a third consumer appears, refactor.
+
+Maps to preference: "engineered enough — not over-engineered."
+
+**STOP** — 4 code quality findings. Going with recommendations: ACCEPT all four.
+
+---
+
+### Section 3 — Test Review (MANDATORY)
+
+**Framework detection:**
+
+```bash
+[ -f roa2web/pytest.ini ] || [ -f roa2web/pyproject.toml ]
+ls roa2web/tests/
+```
+
+roa2web uses pytest + pytest-asyncio. Test fixtures already exist at `tests/fixtures/ocr-samples/`.

+
+**Critical gap:** Every path is a gap because `receipt_handlers.py` is a new file. The plan must include all of these tests as part of the implementation step, not deferred.
+
+**Test plan to add to design doc Assignment:**
+
+1. **Unit tests** — `tests/modules/telegram/test_receipt_handlers.py`:
+   - `test_format_receipt_preview_*` (3 cases: full, all None, low confidence)
+   - `test_confidence_warning_*` (2 cases)
+   - `test_build_oracle_write_config_*` (5 cases incl. unknown server_id fallback)
+   - `test_format_oracle_error_*` (4 ORA codes)
+   - `test_save_to_oracle_*` (mock oracledb, 6 cases)
+   - `test_handle_receipt_callback_*` (7 cases incl. expired, double-press, cancel)
+   - `test_handle_document_message_*` (5 cases)
+   - `test_handle_photo_message_*` (3 cases)
+
+2. **E2E tests** — `tests/e2e/test_receipt_telegram_flow.py` (using PTB test bot or mocks):
+   - PDF send → preview → confirm
+   - Photo send → preview → cancel
+   - 2 simultaneous users (validates concurrent_updates=True)
+
+3. **Oracle integration test** — `tests/integration/test_oracle_receipt_writer.py` (after extracting per FINDING-ARCH-1):
+   - Real dev Oracle DB write + rollback (or use a transaction wrap)

+# Test Plan: Telegram Bonuri Fiscale
+Generated by /plan-eng-review on 2026-05-05
+Branch: feature/telegram-bonuri-fiscale (roa2web)
+Repo: romfast/roa2web
+
+## Affected Pages/Routes
+- Telegram bot: send PDF/JPG/PNG document → preview message
+- Telegram bot: send photo → preview message
+- Telegram inline button: ✅ Confirmă → Oracle write
+- Telegram inline button: ❌ Anulează → cleanup
+
+## Key Interactions to Verify
+- Send PDF receipt → OCR processing message → preview with extracted data → Confirmă button works → Oracle write succeeds → success message with COD
+- Send photo receipt → same flow with JPEG
+- Send unsupported file (.docx) → reject message
+- Press Anulează → cleanup message, file deleted from /tmp
+
+## Edge Cases
+- Send 2nd file while pending exists → "Ai un bon în așteptare" message
+- Wait > 10 minutes after preview, then press Confirmă → "Sesiune expirată"
+- Double-press Confirmă rapidly → 1 save, 2nd press shows "Sesiune expirată"
+- OCR confidence < 60% → ⚠ warning at top of preview
+- OCR returns all-None fields → preview shows N/A everywhere, no crash
+- Oracle ORA-01017 (bad password) → user sees "Credențiale invalide"
+
+## Critical Paths
+- Auth user → submit PDF → confirm → verify ACT_TEMP row in Oracle dev DB
+- 2 users submit photo simultaneously → both get preview within 30s (validates concurrent_updates)
+```
+
+I'll write this to `~/.gstack/projects/romfast-echo-core/moltbot-master-eng-review-test-plan-20260505.md` after the review completes.
+
+**STOP** — Test review complete. 47 gaps, all mandatory. Going with recommendation: write all 47 tests as part of implementation (not deferred).
+
+---
+
+### Section 4 — Performance Review
+
+**FINDING-PERF-1** `[P3] (confidence: 7/10)` Oracle connection per save. `_save_to_oracle` calls `oracledb.connect()` on every confirm. roa2web has an existing Oracle connection pool — `backend/modules/data_entry/db/oracle_pool.py` per the recent commits.
+
+Recommendation: use the existing pool. `from backend.modules.data_entry.db.oracle_pool import get_pool`. If the pool is per-server-id, pass the server_id. Saves ~100-300ms per receipt (TCP handshake + auth round-trip). For a single user at human pace this is barely noticeable, but it's the existing pattern — don't reinvent.
+
+[Layer 1] — use the built-in pool, don't roll your own.
+
+**FINDING-PERF-2** `[P4] (confidence: 6/10)` `asyncio.sleep(0.3)` × 400 = 400 wakeups for a single OCR job. Each wakeup re-queries SQLite. With 4 simultaneous users × 400 wakeups = 1600 SQLite queries per minute. Not catastrophic, but `wait_for_result` could use a longer poll interval (1.0s) with no perceptible UX delta. 120 wakeups instead of 400.
+
+Recommendation: change `OCR_POLL_INTERVAL_S = 1.0`. User won't notice — OCR results don't arrive faster than ~5s anyway.
+
+**FINDING-PERF-3** `[P4] (confidence: 5/10)` Memory: `pending_receipt` dict in `context.user_data` holds the full OCR result + file path. For 100 active users this is ~50KB. Negligible. No issue.
+
+**FINDING-PERF-4** `[P3] (confidence: 7/10)` Caching: `_build_oracle_write_config` reads the secrets file from disk on every confirm. Cache it in module-level dict at first read.
+
+Recommendation:
+```python
+_PASSWORD_CACHE: dict[str, str] = {}
+
+def _read_oracle_password(server_id: str) -> str:
+    if server_id not in _PASSWORD_CACHE:
+        pass_file = PROJECT_ROOT / "secrets" / f"{server_id}_write.oracle_pass"
+        _PASSWORD_CACHE[server_id] = pass_file.read_text().strip() if pass_file.exists() else ""
+    return _PASSWORD_CACHE[server_id]
+```
+
+Saves a disk read per confirm. Trivial. Maps to preference: "explicit > clever, but cache cheap reads."
+
+**STOP** — 4 perf findings. ACCEPT FINDING-PERF-1 (use pool) and FINDING-PERF-2 (1s poll). FINDING-PERF-3 = no action. FINDING-PERF-4 = ACCEPT (trivial).
+
+---
+
+### Outside Voice — skip
+
+Codex availability check + 2-minute outside voice run is valuable for big architecture decisions. This plan is contained: 1 new file, 4 file touches, well-trodden patterns. Skipping.
+
+---
+
+### Failure Modes Summary
+
+| Codepath | Failure | Test? | Error handling? | Silent? |
+|---|---|---|---|---|
+| `_download_file` OSError (/tmp full) | unlikely but real | ✗ | ✗ (FINDING-ERR-1) | YES — **CRITICAL GAP** |
+| `_build_oracle_write_config` unknown server_id | possible after server delete | ✗ | ✗ (FINDING-ERR-2) | YES — **CRITICAL GAP** |
+| `_save_to_oracle` ORA-01017 | wrong password file | ✗ | ✓ (raw msg) | NO (visible to user) |
+| OCR worker process down | bot deployed without worker | ✗ | ✓ (timeout) | NO (timeout msg) |
+| `pending_receipt` race (rapid double-confirm) | reasonable scenario | ✗ | ✓ (pop returns None) | NO ✅ |
+| `secrets/` file missing | first deploy mistake | ✗ | Partial (empty pwd → ORA-01017) | NO (visible) |
+| `receipt_date` malformed in OCR result | model output drift | ✗ | ✗ (FINDING-DATA-1) | YES — **CRITICAL GAP** |
+
+3 critical gaps. All 3 are addressed by CEO findings already accepted into the plan.
+
+---
+
+### Worktree Parallelization
+
+Sequential implementation, no parallelization opportunity. The plan is one feature in one file with cascading dependencies (tests depend on impl, bot_main wiring depends on receipt_handlers.py existing). No independent workstreams. Single worktree, single agent.
+
+---
+
+### NOT in Scope
+
+| Item | Rationale |
+|---|---|
+| WhatsApp parity for the same flow | Separate channel, separate PR. Architecture #1 (extract `oracle_receipt_writer.py`) makes this easier later. |
+| `oracle_receipt_writer.py` extraction | RECOMMEND DOING IT — see FINDING-ARCH-1. If user defers: explicitly list as TODO. |
+| `ocr_client.py` move from scripts/ to modules/ | RECOMMEND DOING IT — FINDING-ARCH-2. If user defers: TODO. |
+| "View in ERP" deep link after save | CEO cherry-pick #4 — needs URL pattern confirmation, defer post-validation |
+| Unify write path through `receipts.py` API | CEO cherry-pick #5 — too much scope (JWT auth for service account, SQLAlchemy session) |
+| Multi-company `CUI_TO_CONT` mapping in DB | Deferred from existing whatsapp_import. Separate refactor. |
+| Web push notification when receipt saved | Out of scope — would couple to web SSE infra |
+
+---
+
+### What Already Exists
+
+| Already in repo | Plan reuses correctly? |
+|---|---|
+| `ocr_client.py::submit_ocr_job` / `wait_for_result` | YES (with path-fix preconditions) |
+| `process_v2.py` PACK_CONTAFIN logic | Adapts pattern (recommend extracting per ARCH-1) |
+| `get_user_auth_data()` | YES |
+| `OracleServerConfig` model | Extended with `write_user` field |
+| `secrets/<server_id>.oracle_pass` convention | Followed for `_write.oracle_pass` |
+| `tests/fixtures/ocr-samples/` (pre-loaded PDFs) | Available for E2E tests |
+| `oracle_pool.py` connection pool | NOT in plan — recommend adding (FINDING-PERF-1) |
+| Existing handler order pattern in `bot_main.py` | YES — receipt callbacks before catch-all |
+
+---
+
+### TODOS.md Proposed Items
+
+(Since no TODOS.md exists in roa2web — these are deferral notes for the design doc Open Questions section.)
+
+1. **Persist `oracle_server_id` in `telegram_users` table** — Already accepted as cherry-pick #3 in CEO review, included in plan.
+2. **Extract `oracle_receipt_writer.py` shared helper** — FINDING-ARCH-1. Going with recommendation: include in this PR.
+3. **Move `ocr_client.py` from scripts/ to modules/** — FINDING-ARCH-2. Going with recommendation: include in this PR.
+4. **"View in ERP" deep link after save** — CEO cherry-pick #4 deferred.
+5. **Unify Telegram write through `receipts.py` API endpoint** — CEO cherry-pick #5 deferred.
+6. **Multi-company CUI→cont mapping in DB or config** — already noted in design doc's Open Question #4.
+
+---
+
+### Updated Assignment (revised checklist for implementation)
+
+```
+1.  git checkout -b feature/telegram-bonuri-fiscale (in roa2web)
+2.  Move ocr_client.py: scripts/whatsapp_import/ → modules/data_entry/services/ocr/queue_client.py
+    Update imports in process_v2.py + test_ocr_simple.py
+    Replace hardcoded QUEUE_DIR with Path(__file__).parents[3] / "data/ocr_queue"
+3.  Extract oracle_receipt_writer.py:
+    Create modules/data_entry/services/oracle_receipt_writer.py with write_receipt(receipt_dict, oracle_cfg) -> tuple[int, str]
+    Adapt process_v2.py to call it
+4.  Add backend/config.py: write_user: Optional[str] = None to OracleServerConfig
+5.  Migration: alembic revision --autogenerate -m "add oracle_server_id to telegram_users"
+    Modify link_user_to_oracle to accept + store server_id
+    Modify get_user_auth_data to return server_id
+6.  Implement receipt_handlers.py:
+    - Module constants (FINDING-CQ-2)
+    - _format_receipt_preview + _confidence_warning (FINDING-CQ-1)
+    - _build_oracle_write_config with None-server fallback (FINDING-ERR-2)
+    - _format_oracle_error (FINDING-ERR-3)
+    - Caching for password file (FINDING-PERF-4)
+    - _save_to_oracle delegates to oracle_receipt_writer
+    - handle_document/photo/callback with proper error handling (FINDING-CQ-3)
+    - Date parse with try/except (FINDING-DATA-1)
+    - OSError handling around download (FINDING-ERR-1)
+    - Duplicate pending guard (cherry-pick #2)
+    - Low-confidence warning in preview (cherry-pick #1)
+    - Structured logging at each step (FINDING-OBS-1)
+7.  Wire bot_main.py:
+    - Add .concurrent_updates(True) to Application.builder() (FINDING-ARCH-3)
+    - Register 3 new handlers BEFORE catch-all CallbackQueryHandler
+    - Add startup cleanup scan: glob /tmp/receipt_*.* and unlink at start
+8.  Create secrets/<server_id>_write.oracle_pass on server (deploy step, not in git)
+9.  Verify .gitignore covers secrets/*.oracle_pass (FINDING-SEC-1)
+10. Write all 47 unit tests per Section 3 coverage diagram
+11. Write 3 E2E tests (PDF flow, photo flow, concurrent users)
+12. Write Oracle integration test against dev DB
+13. End-to-end manual test with real bon → confirm in Oracle ACT_TEMP
+14. Verify on production-like setup that OCR worker is running before deploy
+```
+
+15 steps. Up from 9. Every addition is grounded in a finding.
+

+# Ralph Progress Log
+Started: 2026-05-05 23:01
+Project: roa2web-telegram-bonuri
+---
+
+## Iterație: 2026-05-05 23:15
+### Story implementat: US-003 - Adaugă câmpul write_user în OracleServerConfig (tags: backend)
+### Status: Complete
+
+### Gates rulate:
+- Pytest: PASS (5/5 tests)
+- /review (backend): PASS — 2 minor auto-fixes applied
+  - Clarified misleading comment on write_user (fallback is caller's responsibility, not OracleServerConfig's)
+  - Renamed duplicate test to better express its purpose (explicit None vs omitted)
+
+### Fișiere atinse:
+- backend/config.py — write_user: Optional[str] = None adăugat la OracleServerConfig
+- tests/backend/test_oracle_server_config.py — 5 unit tests noi (fișier nou)
+
+### Learnings:
+- write_user field este groundwork pentru US-005 (receipt_handlers.py va folosi get_write_user)
+- Specialist review a identificat: oracle_receipt_writer.py (US-002, untracked) are probleme de connection pooling și float precision pentru money — de adresat în US-002 retry
+
+### Next:
+- US-004: Migrare DB oracle_server_id în telegram_users (independent, priority 40)
+- US-007: Verifică .gitignore pentru secrets/*.oracle_pass (independent, priority 70)
+---
+## Rate limit la iter 8 — sleep 1800
+
+## Iterație: 2026-05-06
+### Story implementat: US-007 - Verifică .gitignore pentru secrets/*.oracle_pass (tags: infra)
+### Status: Complete
+
+### Gates rulate:
+- Smoke test (infra): PASS — toate 3 AC verificate manual
+  - AC1: .gitignore line 436 `secrets/` este pattern echivalent pentru `secrets/*.oracle_pass`
+  - AC2: `git check-ignore secrets/test_write.oracle_pass` → exit 0
+  - AC3: `git ls-files secrets/` → 0 fișiere .oracle_pass tracked
+- /review: N/A — nicio modificare de cod necesară (gitignore deja corect)
+
+### Fișiere atinse:
+- Niciun fișier modificat — .gitignore era deja corect cu `secrets/` pe linia 436
+
+### Learnings:
+- .gitignore deja excludea întregul director `secrets/` (linia 436), deci `*.oracle_pass` era acoperit
+- Pattern `secrets/` este mai broad decât `secrets/*.oracle_pass` — acoperă tot directorul
+
+### Next:
+- US-002: Extrage oracle_receipt_writer.py (failed, max_retries — needs manual intervention)
+- US-004: Migrare DB oracle_server_id în telegram_users (failed, max_retries — needs manual intervention)
+- US-005/006/008/009/010: Toate blocked de US-002 și US-004
+---
+
+## Intervenție manuală: 2026-05-08
+### Stories deblocate: US-002 și US-004 (intervenție manuală Claude Code)
+
+### US-002: Extrage oracle_receipt_writer.py
+### Status: Complete
+
+### Fișiere atinse:
+- backend/modules/data_entry/services/oracle_receipt_writer.py — creat
+- backend/modules/data_entry/services/__init__.py — exportat write_receipt
+- backend/scripts/whatsapp_import/process_v2.py — import actualizat
+- backend/scripts/whatsapp_import/whatsapp_flow.py — import actualizat
+
+### US-004: Migrare DB oracle_server_id în telegram_users
+### Status: Complete (10/10 teste pass)
+
+### Fișiere atinse:
+- shared/database/app_db.py — oracle_server_id în CREATE TABLE
+- backend/modules/telegram/db/operations.py — server_id în link_user_to_oracle()
+- backend/modules/telegram/auth/linking.py — pass/return server_id
+- backend/alembic.ini — config Alembic
+- backend/migrations/versions/20260505_add_oracle_server_id_to_telegram_users.py — migrare idempotentă
+- tests/backend/test_telegram_oracle_server_id.py — 5 teste, toate pass
+
+### Cauza blocajului original:
+- aiosqlite, pydantic-settings, httpx nu erau instalate în test env
+- patch("backend.modules.telegram.auth.linking...") necesita pre-import cu mock telegram
+
+### Next:
+- US-005: receipt_handlers.py (priority 50)
+- US-006: bot_main.py wire (priority 60)
+- US-008, 009, 010: teste
+---
+
+## Intervenție manuală US-005: 2026-05-08
+### Story implementat: US-005 - receipt_handlers.py (tags: backend, db)
+### Status: Complete (intervenție manuală — gate-urile au depășit 30 turns)
+
+### Gates rulate manual:
+- Syntax check: PASS
+- AC1 funcții (9/9): PASS
+- AC2 constante (5/5): PASS
+- AC3 error handling specific: PASS (fără bare except Exception)
+- AC4 ORA codes (3/3): PASS
+- AC5 password cache: PASS
+- AC7 duplicate guard: PASS
+- AC8 confidence warning: PASS
+- AC9 TTL expired: PASS
+- AC10 oracle_pool.get_pool(): PASS
+
+### Fișiere atinse:
+- backend/modules/telegram/handlers/receipt_handlers.py — creat (459 linii)
+- backend/modules/telegram/handlers/__init__.py — creat
+- backend/modules/data_entry/services/oracle_receipt_writer.py — acceptă Connection din pool
+- shared/database/oracle_pool.py — adăugat get_pool(server_id)
+
+### Next: US-006 (wire bot_main.py), US-008/009/010 (teste)
+---
+
+## Iterație: 2026-05-08
+### Story implementat: US-006 - Wire bot_main.py cu handlers și concurrent_updates (tags: backend)
+### Status: Complete
+
+### Gates rulate:
+- Syntax check (py_compile): PASS pentru bot_main.py și receipt_handlers.py
+- AC verification (AST): PASS 8/8
+  - AC1 .concurrent_updates(True): PASS
+  - AC2 MessageHandler(Document.PDF | Document.IMAGE): PASS
+  - AC3 MessageHandler(PHOTO): PASS
+  - AC4 CallbackQueryHandler pattern=r'^receipt:' ÎNAINTE de catch-all: PASS
+  - AC5 startup_cleanup() cu glob '/tmp/receipt_*.*' și missing_ok=True: PASS
+  - AC6 create_telegram_application există + syntax valid: PASS (full import deferat — deps lipsă local)
+- /review (backend): PASS
+  - Handler ordering: corect (receipt CB înregistrat înainte de catch-all)
+  - concurrent_updates(True) thread-safety: OK — state keyed per-user, PTB rulează single event loop (asyncio, nu threads)
+  - startup_cleanup blast radius: OK — prefix `receipt_` suficient de specific; single-worker deployment per CLAUDE.md previne race orfani
+  - Error handling per-fișier OSError + outer broad except în startup(): appropriate (best-effort, nu blochează startup-ul)
+
+### Fișiere atinse:
+- backend/modules/telegram/bot_main.py (+57 linii, -2):
+  - Import `glob` adăugat
+  - Import receipt handlers (handle_document_message, handle_photo_message, handle_receipt_callback)
+  - Application.builder() refactored cu .concurrent_updates(True)
+  - 3 handler-uri noi înregistrate ÎNAINTE de catch-all CallbackQueryHandler
+  - Funcție nouă `startup_cleanup() -> int` care unlink-uiește orfanii din /tmp/receipt_*.*
+  - Apel `startup_cleanup()` adăugat la începutul `startup()` cu try/except non-critical
+
+### Learnings:
+- python-telegram-bot dispatchează handler-ele în ordinea înregistrării în același group → CallbackQueryHandler cu pattern specific TREBUIE înregistrat înainte de catch-all
+- concurrent_updates(True) în PTB rulează update-urile în task-uri asyncio separate pe același event loop (nu threads), deci dict mutations între await-uri sunt sigure dacă cheile nu se suprapun
+- startup_cleanup este safe doar în deployment single-worker (vezi ARCHITECTURE-DECISIONS.md `--workers 1`); altfel ar putea unlink-ui un fișier activ al altei instanțe
+
+### Next:
+- US-008: Unit tests pentru receipt_handlers (acum unblocked)
+- US-009: E2E tests pentru flow Telegram bonuri (acum unblocked)
+- US-010: Oracle integration test pentru oracle_receipt_writer (deja unblocked după US-002)

+## Rate limit la iter 4 — sleep 1800
+
+## Iterație: 2026-05-08
+### Story implementat: US-009 - Write E2E tests pentru flow Telegram bonuri (tags: backend)
+### Status: Complete
+
+### Gates rulate:
+- Pytest (3 E2E + 35 unit = 38 total): PASS în ambele ordini de colectare
+- /review (backend): PASS — 3 review fix-uri aplicate înainte de commit:
+  1. Izolare stubs telegram: NU mai mut `sys.modules['telegram']` când există deja; rebind doar `rh.InlineKeyboardButton/Markup` pe modul (păstrează independența cross-file)
+  2. Concurrency assertion: înlocuit `elapsed < 0.5` (slabă: serial cu sleep 50ms ≈ 0.4s ar trece) cu in-flight counter `state["max_in_flight"] == 2` care dovedește overlap real
+  3. Adăugat verificare suffix `.pdf` și prefix `receipt_` pe temp file în testul PDF
+
+### Fișiere atinse:
+- tests/e2e/__init__.py (nou)
+- tests/e2e/test_receipt_telegram_flow.py (nou, 3 teste E2E):
+  * test_e2e_pdf_send_preview_confirm_success — happy path PDF: download → OCR → preview → confirm → cod 7777 + temp unlinked
+  * test_e2e_photo_send_preview_cancel_cleanup — photo: largest resolution → preview → cancel → temp file `.exists() == False`
+  * test_e2e_concurrent_two_users_get_previews — 2 user_ids simultan, in-flight counter dovedește overlap, elapsed<30s
+
+### AC verification:
+- AC1 fișier există: PASS
+- AC2 PDF flow (OCR processing → preview → confirm → success): PASS
+- AC3 photo flow (cancel + temp deleted): PASS
+- AC4 concurrent <30s + overlap real: PASS (max_in_flight=2)
+- AC5 pytest PASS: PASS (3/3)
+
+### Learnings:
+- Cross-file `sys.modules` mutation creează test-order coupling între unit test și E2E test pe același modul stubbed; soluție: rebind doar atributele pe modulul under-test (`rh.X`) după import, nu modulul stub însuși
+- Asserting `elapsed<X` pentru concurency e nesigur (serial poate trece accidental); folosește in-flight counter sau `asyncio.Barrier` care ar deadlock sub serial
+- python-telegram-bot stubbed cu `MagicMock` direct ca clasă breakuiește când codul real face `MagicMock([list])` — MagicMock interpretează primul arg pozițional ca spec; soluție: stub-uri proper (clase mici) pentru obiecte construite de cod, nu MagicMock pur
+- Reviewer a flagat bug paralel în receipt_handlers.py:447-459 (no cleanup on `oracledb.DatabaseError` / `asyncio.TimeoutError`): pending-state și temp-file rămân până la TTL 600s. Out-of-scope pentru US-009; merită follow-up pentru US-005.

+# Ralph - Instrucțiuni pentru Iterație (smart gates)
+
+Ești un agent autonom care implementează user stories dintr-un PRD. Aceasta este O SINGURĂ iterație — implementezi UN singur story, validezi prin gate-urile relevante, apoi te oprești.
+
+## Workflow per iterație (4 faze, gates condiționale pe `story.tags`)
+
+### Faza 0: Citește contextul
+
+- PRD-ul (`prd.json`) și `progress.txt` sunt furnizate în context.
+- Identifică următorul story candidate:
+  - `passes != true` ȘI `failed != true` ȘI `blocked != true`
+  - DAG: toate ID-urile din `dependsOn[]` au `passes == true` (altfel sare la următorul independent)
+  - Cea mai mică `priority` printre cele eligibile.
+- Notează `techStack.commands` (lint, typecheck, test, start) și `techStack.port`.
+- Notează `story.tags[]` — alegerea Faza 3 depinde de ele.
+
+### Faza 1: IMPLEMENTARE (mereu)
+
+1.1. **Branch management** — verifică să fii pe `branchName` din PRD; checkout/create dacă lipsește.
+1.2. **Citește acceptance criteria** — fiecare criteriu e un test mental concret de trecut.
+1.3. **Implementează cod minimal** — DOAR ce cere story-ul. Urmează patterns existente. Fără over-engineering, fără side features.
+1.4. **Update `notes`** în `prd.json` cu fișierele atinse (pentru audit ulterior).
+
+### Faza 2: QUALITY BASE (mereu, înainte de gates)
+
+Folosește `techStack.commands`:
+
+```bash
+{techStack.commands.typecheck}   # ex: npm run typecheck / mypy .
+{techStack.commands.lint}        # ex: npm run lint / ruff check .
+{techStack.commands.test}        # ex: npm test / pytest
+```
+
+**Loop intern**: dacă vreuna eșuează → repară și repetă, max 3 retries în această fază. Dacă încă fail după 3, ieși cu sumar de erori în `progress.txt` (ralph.sh va decide retry-ul iterației).
+
+### Faza 3: SMART GATES (dispatcher pe `story.tags`)
+
+Tags posibile: `ui`, `db`, `vercel`, `refactor`, `docs`, `backend`, `infra`.
+
+Aplică DOAR gate-urile potrivite — **nu rulează toate**:
+
+| Tag         | Gate                                                                                  |
+|-------------|---------------------------------------------------------------------------------------|
+| `refactor`  | `/workflow:simplify` pe diff (reduce complexity fără behavior change)                 |
+| `ui`        | `/qa` Playwright/agent-browser snapshot pe `localhost:{techStack.port}` + screenshot  |
+| `ui` + `requiresDesignReview` | `/plan-design-review` pe screenshot capturat                        |
+| `vercel`    | push branch + `gh pr checks --watch` (timeout 5 min); fail dacă PR checks eșuează     |
+| `db`        | verify schema diff (alembic / prisma migrate diff / `psql \\d+ tablename`)            |
+| `docs`      | doar typecheck base (Faza 2 e suficient); skip gate dedicat                           |
+| `backend`   | `/review` pe diff (intern — second pass review pe API contracts, error handling)      |
+| `infra`     | `/review` pe diff + manual smoke test al modificărilor (CI config, Dockerfile, etc.)  |
+| _(tags vide)_ | **run-all-gates fallback** — `/review` + `/qa` + `/workflow:simplify` (safe default) |
+
+**Mecanism**: skill-urile gstack se invocă prin text mention în prompt — Claude (subprocess `claude -p`) le vede ca tool-uri disponibile via `~/.claude/skills/gstack/`.
+
+**Multi-tag**: rulează gate-uri pentru fiecare tag (ex: `["ui", "backend"]` → atât `/qa` cât și `/review`).
+
+**Important**: dacă vreun gate eșuează, NU marca `passes=true`. Repară (max 3 fix-uri în iterație) sau lasă pentru iterația următoare (ralph.sh se ocupă de retry counter).
+
+### Faza 4: COMMIT + MARK
+
+4.1. **Commit** cu mesaj descriptiv:
+```
+feat: [Story ID] - [Story Title]
+
+- ce ai schimbat (1-3 bullets)
+- gates rulate: typecheck PASS, lint PASS, /qa PASS
+```
+
+4.2. **Update `prd.json`**:
+- `passes: true` DOAR DACĂ toate gate-urile relevante au pasat
+- `notes` populat cu rezultate gate (ex: "qa: ok, design-review: 8/10")
+
+4.3. **Append `progress.txt`**:
+```markdown
+## Iterație: [timestamp]
+### Story implementat: [ID] - [Title] (tags: [ui, backend])
+### Status: Complete / Partial / Failed
+
+### Gates rulate:
+- Typecheck: PASS
+- Lint: PASS
+- Tests: PASS/SKIP
+- /qa (ui): PASS — screenshot la scripts/ralph/screenshots/...
+- /review (backend): PASS
+
+### Learnings:
+- [Patterns descoperite, gotchas]
+
+### Next:
+- [Stories eligibile pentru iterația următoare]
+---
+```
+
+## Reguli importante
+
+1. **UN SINGUR STORY PE ITERAȚIE** — nu implementa mai mult de un story.
+2. **DAG STRICT** — nu sări peste `dependsOn` neîmplinite.
+3. **GATES PE TAGS** — rulează doar ce e relevant; tags vide = run-all-gates fallback.
+4. **NU MARCA `passes=true` cu gate failed** — altfel ralph.sh nu va relua story-ul.
+5. **FII CONCIS** — fără over-engineering, fără docs auto-generate dacă story-ul nu cere.
+
+## Comenzi agent-browser (referință rapidă pentru gate `ui`)
+
+```bash
+agent-browser navigate "http://localhost:{techStack.port}"

+
+Acest director conține parole Oracle, chei SSH și alte credențiale.
+**Tot conținutul (cu excepția acestui README) e gitignored.**
+
+---
+
+## Fișiere necesare
+
+### Pentru fiecare server Oracle din `backend/ssh-tunnels.json`
+
+#### `{server_id}.oracle_pass` — parola user-ului READ
+
+Parola pentru `ORACLE_USER` (user de citire), folosită de modulul Reports și
+pentru tunelul SSH spre Oracle.
+
+Exemplu: dacă `ssh-tunnels.json` are `"id": "vending"`, creează:
+```bash
+echo -n 'parola_read_user' > secrets/vending.oracle_pass
+chmod 600 secrets/vending.oracle_pass
+```
+
+#### `{server_id}_write.oracle_pass` — parola user-ului WRITE (US-003, US-005)
+
+Parola pentru user-ul cu drepturi de scriere (`{user}_AUTO` by default, sau
+`OracleServerConfig.write_user` dacă e setat). Folosită de
+`backend/modules/data_entry/services/oracle_receipt_writer.py` pentru a scrie
+bonuri în `ACT_TEMP` via `PACK_CONTAFIN`.
+
+Exemplu pentru `vending`:
+```bash
+echo -n 'parola_write_user' > secrets/vending_write.oracle_pass
+chmod 600 secrets/vending_write.oracle_pass
+```
+
+> **Notă (US-005):** dacă fișierul lipsește, `_build_oracle_write_config()`
+> face fallback la parola de read și logează un warning. Pentru producție,
+> setează parolă dedicată pentru write user.
+
+### Pentru fiecare server cu autentificare SSH cu parolă
+
+#### `{server_id}.ssh_pass`
+
+```bash
+echo -n 'parola_ssh' > secrets/vending.ssh_pass
+chmod 600 secrets/vending.ssh_pass
+```
+
+### Pentru fiecare server cu autentificare SSH cu cheie
+
+#### `{server_id}.ssh_key`
+
+Cheia privată SSH (PEM/OpenSSH format).
+
+```bash
+cp ~/.ssh/id_ed25519_oracle secrets/romfast.ssh_key
+chmod 600 secrets/romfast.ssh_key
+```
+
+---
+
+## Verificare
+
+```bash
+# Toate fișierele trebuie să fie chmod 600 (owner-only)
+ls -la secrets/
+# -rw------- 1 user user  20 ... vending.oracle_pass
+# -rw------- 1 user user  18 ... vending_write.oracle_pass
+
+# Verifică că secrets/ e gitignored
+git check-ignore secrets/vending.oracle_pass
+# secrets/vending.oracle_pass
+
+# Niciun fișier .oracle_pass nu trebuie să apară în git
+git ls-files secrets/
+# (gol — sau doar README.md)
+```
+

+
+## Trouble­shooting
+
+| Eroare | Cauză | Fix |
+|--------|-------|-----|
+| `ORA-01017: invalid username/password` | Parolă greșită în `.oracle_pass` | Re-creează fișierul fără newline trailing: `echo -n` |
+| `Permission denied (publickey,password)` | SSH auth failed | Verifică `chmod 600` pe `.ssh_key` / `.ssh_pass` |
+| Warning "No write password file '{id}_write.oracle_pass' found" | Lipsește fișierul write | Creează `{id}_write.oracle_pass` cu parola corectă |
