+Autonomous Loop — Curator-pattern background engine for report_agent.
+
+Adapted from hermes-agent-repo/agent/curator.py. Provides an inactivity-
+triggered background engine that can:
+  - Auto-generate insights reports when idle
+  - Suggest cron job schedules based on usage patterns
+  - Run background maintenance tasks (prune old sessions, optimize DB)
+
+The Curator pattern from Hermes uses periodic inactivity checks:
+when no user interaction happens for N minutes, the agent autonomously
+runs maintenance or insight-generation tasks.
+
+Usage:
+    from agent.report_agent.autonomous_loop import ReportCurator
+
+    curator = ReportCurator()
+
+    # Check if we should run autonomous tasks
+    if curator.should_run():

+Hermes Bridge — Adapter layer providing Hermes-compatible interfaces for report_agent.
+
+Ports essential patterns from the Hermes Agent core without importing hermes-agent-repo
+directly (avoiding its complex dependency tree). Each component is a self-contained
+adaptation of the corresponding Hermes module:
+
+  - FailoverReason / ClassifiedError  ← agent/error_classifier.py
+  - ReportSessionDB                   ← hermes_state.py (SessionDB)
+  - Cost estimation helpers           ← agent/insights.py / usage_pricing.py
+
+Usage:
+    from agent.report_agent.hermes_bridge import (
+        FailoverReason, ClassifiedError, classify_error,

+# 💡 IDEA #23: Report Agent — Deep Hermes Core Integration
+
+## Origin
+User request: "report agent sao đơn giản thế bro — làm sâu vào rồi móc toàn bộ core của hermes agent"
+
+## Description
+Hiện tại `report_agent` chỉ sử dụng **surface-level** integration với Hermes:
+- `scheduler.py` import `cron.jobs.create_job` nhưng chỉ tạo 1 job duy nhất (daily sales).
+- Không có **InsightsEngine** để phân tích session history.
+- Không có **ErrorClassifier** cho self-healing retry pipeline.
+- Không có **ContextCompressor** cho token management.
+- Không có **Curator** pattern cho lifecycle management.
+- Không có **SessionDB** cho persistent state tracking.
+- Không có **session_search** để crawl lịch sử tìm insight cho report.
+
+## Goal
+Biến `report_agent` từ một "dumb report generator" thành một **autonomous insight engine** 
+bằng cách deep-integrate các core module từ `hermes-agent-repo/`:
+
+1. **InsightsEngine** → Tự động tạo usage/performance reports từ session data
+2. **SessionDB** → Persistent state tracking cho report lifecycle  
+3. **ErrorClassifier** → Self-healing pipeline (retry/compress/fallback)
+4. **ContextCompressor** → Manage token budget khi report data quá lớn
+5. **Curator pattern** → Background maintenance + lifecycle state transitions
+6. **session_search** → Tìm relevant sessions để enrich report context
+7. **kanban_tools** → Task orchestration cho multi-step report pipelines
+
+## Type
+Feature Enhancement (Pipeline A)

plan/possible/23_report_agent_hermes_deep_report.md

+# 📊 Feasibility Report #23: Report Agent — Deep Hermes Core Integration
+
+## Verdict: 🟢 POSSIBLE
+
+## Assessment
+
+### Feasibility Score: 9/10
+
+**Why POSSIBLE:**
+1. **All source code available** — `hermes-agent-repo/` nằm cùng worktree, full access.
+2. **No new dependencies** — Tất cả modules cần thiết đã có sẵn trong hermes-agent-repo.
+3. **Clear API surface** — `InsightsEngine(db)`, `SessionDB(path)`, `FailoverReason`, `ContextCompressor` đều có stable public APIs.
+4. **Copy + Adapt pattern** — Ta sẽ copy adapter modules từ hermes core, modify cho Canifa context, không fork nguyên bộ.
+5. **Backward compatible** — Existing `report_queue.py` và `main_graph.py` không bị break.
+
+### Technical Risks
+| Risk | Severity | Mitigation |
+|---|---|---|
+| `hermes_state` cần `hermes_constants` | Low | Copy `get_hermes_home()` logic, redirect to Canifa SQLite path |
+| `InsightsEngine` cần `usage_pricing` | Low | Mock pricing với flat $0.00 — ta dùng Codex/own tokens |
+| `cron.jobs` cần `croniter` | Low | Already optional — fallback to APScheduler |
+| `session_search` cần `auxiliary_client` | Medium | Bypass — use our own `call_llm()` from `core.py` |
+
+### Dependencies Available
+- ✅ `agent/insights.py` — Session analytics engine
+- ✅ `hermes_state.py` — SQLite SessionDB with FTS5
+- ✅ `agent/error_classifier.py` — API error taxonomy
+- ✅ `agent/context_compressor.py` — Token management
+- ✅ `agent/curator.py` — Background lifecycle patterns
+- ✅ `tools/session_search_tool.py` — FTS5 session search
+- ✅ `tools/kanban_tools.py` — Task orchestration
+- ✅ `cron/jobs.py` — Persistent cron scheduling
+
+## Conclusion
+All infrastructure exists. This is a **wiring + adaptation** task, not a greenfield build.
+Estimated effort: ~90 minutes of focused execution.
