+## Router pipeline (User → Router → Profile → Job → Resume → Cover → Review)
+- Implemented in `agents/pipeline.py` and exposed via API in `api_llm_integration.py` (`/api/llm/pipeline_run`).
+- Agents:
+  - `RouterAgent`: routes based on payload state
+  - `ProfileAgent`: parses CV to structured profile (LLM with fallback)
+  - `JobAgent`: analyzes job posting (LLM with fallback)
+  - `CVOwnerAgent` and `CoverLetterAgent`: draft documents (Gemini, per-agent keys)
+  - Review: contradiction checks and memory persist
+- Temporal tracking: on review, a `drafted` status is recorded in the temporal KG with issues metadata.

+
+---
+
+## Hugging Face / Gradio (interactive controls)
+- In the CV Analysis tab, you can now set:
+  - **Refinement cycles** (1–5)
+  - **Exact target length** (characters) to enforce resume and cover length deterministically
+  - **Layout preset**: `classic`, `modern`, `minimalist`, `executive`
+    - classic: Summary → Skills → Experience → Education (above the fold for Summary/Skills)
+    - modern: Summary → Experience → Skills → Projects/Certifications → Education
+    - minimalist: concise Summary → Skills → Experience → Education
+    - executive: Summary → Selected Achievements (3–5) → Experience → Skills → Education → Certifications
+
+---
+
+## UK resume/cover rules (built-in)
+- UK English and dates (MMM YYYY)
+- Current role in present tense; previous roles in past tense
+- Digits for numbers; £ and % normalization
+- Remove first‑person pronouns in resume bullets; maintain active voice
+- Hard skills first (max ~10), then soft skills; verbatim critical JD keywords in bullets
+- Strip DOB/photo lines; compress older roles (>15 years) to title/company/dates
+
+These rules are applied by `agents/cv_owner.py` and validated by checklists.
+
+---
+
+## Checklists and observability
+- Checklists integrate guidance from:
+  - Reed: CV layout and mistakes
+  - The Muse: action verbs and layout basics
+  - Novorésumé: one‑page bias, clean sections, links
+  - StandOut CV: quantification, bullet density, recent‑role focus
+- Observability tab aggregates per‑agent events and displays checklist outcomes. Events are stored in `memory/data/events.jsonl`.
+
+---
+
+## Scripts (headless runs)
+- Capco (Anthony Lui → Capco):
+```powershell
+python .\scripts\run_with_env.py .\scripts\run_anthony_capco.py
+```
+- Anthropic (Anthony Lui → Anthropic):
+```powershell
+python .\scripts\run_with_env.py .\scripts\run_anthropic_job.py
+```
+- Pipeline (Router + Agents + Review + Events):
+```powershell
+python .\scripts\run_with_env.py .\scripts\pipeline_anthony_capco.py
+```
+
+These scripts print document lengths, agent diagnostics, and whether Gemini is enabled. Set `.env` with `LLM_PROVIDER=gemini`, `LLM_MODEL=gemini-2.5-flash`, and `GEMINI_API_KEY`.
+
+---
+
+## Temporal knowledge graph (micro‑memory)
+- `agents/temporal_tracker.py` stores time‑stamped triplets with non‑destructive invalidation.
+- Integrated in pipeline review to track job application states and history.
+- Utilities for timelines, active applications, and pattern analysis included.
+
+---
+
+## Parallel agents + meta‑agent demo
+- Notebook: `notebooks/agents_parallel_demo.ipynb`
+- Runs 4 analysis agents in parallel and combines outputs via a meta‑agent, with a timeline plot.
+- Uses the central LLM client (`services/llm.py`) with `LLM_PROVIDER=gemini` and `LLM_MODEL=gemini-2.5-flash`.
+
+Run (Jupyter/VSCode):
+```python
+%pip install nest_asyncio matplotlib
+# Ensure GEMINI_API_KEY is set in your environment
+```
+Open and run the notebook cells.
+
+---
+
+## LinkedIn OAuth (optional)
+1) Create a LinkedIn Developer App, then add redirect URLs:
+```
+http://localhost:8501
+http://localhost:8501/callback
+```
+2) Products: enable “Sign In with LinkedIn using OpenID Connect”.
+3) Update `.env` and set `MOCK_MODE=false`.
+4) In the UI, use the “LinkedIn Authentication” section to kick off the flow.
+
+Notes:
+- LinkedIn Jobs API is enterprise‑only. The system uses Adzuna + other sources for job data.
+
+---
+
+## Job sources
+- **Adzuna**: global coverage, 5,000 free jobs/month
+- **Resilient aggregator** and optional **JobSpy MCP** for broader search
+- **Custom jobs**: add your own postings in the UI
+- Corporate SSL environments: Adzuna calls auto‑retries with `verify=False` fallback
+
+---
+
+## LLMs and configuration
+- Central client supports OpenAI, Anthropic, and Gemini with per‑agent Gemini keys (`services/llm.py`).
+- Recommended defaults for this project:
+  - `LLM_PROVIDER=gemini`
+  - `LLM_MODEL=gemini-2.5-flash`
+- Agents pass `agent="cv|cover|parser|match|tailor|chat"` to use per‑agent keys when provided.
+
+---
+
+## Advanced agents (built‑in)
+- **Parallel processing**: 3–5× faster multi‑job drafting
+- **Temporal tracking**: time‑stamped history and pattern analysis
+- **Observability**: tracing, metrics, timeline visualization
+- **Context engineering**: flywheel learning, L1/L2/L3 memory, scalable context
+
+Toggle these in the HF app under “🚀 Advanced AI Features”.
+
+---
+
+## LangExtract + Gemini
+- Uses the same `GEMINI_API_KEY` (auto‑applied to `LANGEXTRACT_API_KEY` when empty)
+- Official `langextract.extract(...)` requires examples; the UI also exposes a robust regex‑based fallback (`services/langextract_service.py`) so features work even when cloud extraction is constrained
+- In HF app (“🔍 Enhanced Job Analysis”), you can:
+  - Analyze job postings (structured fields + skills)
+  - Optimize resume for ATS (score + missing keywords)
+  - Bulk analyze multiple jobs
+
+---
+
+## Office exports
+- **Word** (`services/word_cv.py`): resumes + cover letters (5 templates; `python‑docx` fallback)
+- **PowerPoint** (`services/powerpoint_cv.py`): visual CV (4 templates; `python‑pptx` fallback)
+- **Excel** (`services/excel_tracker.py`): tracker with 5 analytical sheets (`openpyxl` fallback)
+- MCP servers supported when available; local libraries are used otherwise
+
+In HF app, after generation, expand:
+- “📊 Export to PowerPoint CV”
+- “📝 Export to Word Documents”
+- “📈 Export Excel Tracker”
+
+---
+
+## Hugging Face minimal Space branch
+- Clean branch containing only `app.py` and `requirements.txt` for Spaces.
+- Branch name: `hf-space-min` (push from a clean worktree).
+- `.gitignore` includes `.env` and `.env.*` to avoid leaking secrets.
+
+---
+
+## Tests & scripts
+- Run test suites in `tests/`
+- Useful scripts: `test_*` files in project root (integration checks)
+
+---
+
+## Security
+- OAuth state validation, input/path/url sanitization
+- Sensitive data via environment variables; avoid committing secrets
+- Atomic writes in memory store
+
+---
+
+## Run summary
+- Streamlit: `python -m streamlit run app.py --server.port 8501`
+- Gradio/HF: `PORT=7861 python hf_app.py`
+
+Your system is fully documented here in one place and ready for local or HF deployment.
