fix(backend): add missing matplotlib dependency for podcast composer

The podcast B-roll composer imports matplotlib for chart rendering, so adding it to backend requirements prevents import failures in fresh setups.

+# ALwrity Project
+
+## What This Is
+ALwrity is an AI-powered content creation platform that helps users generate various types of content including podcasts, videos, blogs, and social media content. The platform features a React frontend and a FastAPI backend with onboarding workflows, API key management, and content generation capabilities.
+
+## Core Value
+To provide an all-in-one AI content creation suite that simplifies the content production process for creators, marketers, and businesses.
+
+## Current Focus
+Based on recent git commits, the team has been working on:
+- Podcast production features (voice cloning, avatar generation, B-roll integration)
+- Onboarding flow improvements
+- Backend stability and debugging
+- Frontend UI/UX enhancements
+
+## Requirements
+
+### Validated
+- User authentication (Clerk)
+- API key management for AI providers
+- Basic podcast generation workflow
+- File storage and media handling
+
+### Active
+- Podcast script generation and editing
+- Voice cloning and avatar creation
+- B-roll scene rendering and integration
+- Onboarding flow completion tracking
+- API endpoint stability and debugging
+
+### Out of Scope
+- Mobile applications (currently web-only)
+- Enterprise team collaboration features
+- Advanced analytics dashboard
+
+## Key Decisions
+- Using FastAPI for backend performance
+- React with Material-UI for frontend consistency
+- Modular API design for extensibility
+- Database-first approach for persistence
+
+## Constraints
+- Must maintain backward compatibility with existing API
+- Deployment targets include both development and production environments
+- Must support multiple AI providers (OpenAI, HuggingFace, etc.)
+- Budget-conscious resource usage for AI API calls

+# Project State
+
+## Project Reference
+**Core Value**: ALwrity is an AI-powered content creation platform that helps users generate various types of content including podcasts, videos, blogs, and social media content.
+
+**Current Focus**: Based on recent development activity, the team is implementing Phase 2 of the WaveSpeed AI integration roadmap - Hyper-Personalization features for the Persona system, including voice training and avatar creation.
+
+## Current Position
+**Phase**: 2 of 3 - Hyper-Personalization
+**Plan**: 3 of 5 - Persona Avatar Creation & Integration
+**Status**: In Progress - Working on avatar service implementation and frontend UI for avatar creation
+
+## Progress
+Progress: [███████░░] 70%
+
+## Recent Decisions
+1. **Avatar Service Architecture**: Decided to create a shared avatar service in backend/services/wavespeed/avatar/ for reuse across LinkedIn and Persona modules
+2. **UI Framework**: Continuing with Material-UI (MUI) for consistent avatar creation interface
+3. **Storage Strategy**: Using cloud storage for avatar assets with metadata tracking in PostgreSQL
+4. **Generation Queue**: Implementing asynchronous processing for avatar generation to prevent API timeouts
+
+## Pending Todos
+- [ ] Complete avatar generation API endpoints
+- [ ] Implement avatar library management UI
+- [ ] Add avatar preview functionality
+- [ ] Create avatar upload/download capabilities
+- [ ] Integrate avatar selection into Persona dashboard
+- [ ] Add usage tracking and cost estimation for avatar generation
+- [ ] Write comprehensive tests for avatar service
+- [ ] Update documentation for avatar feature
+
+## Blockers/Concerns
+- **WaveSpeed API Rate Limits**: Need to implement proper queuing and retry mechanisms
+- **Storage Costs**: Avatar storage could become expensive at scale - need to implement cleanup policies
+- **Generation Time**: Avatar generation can take 30-60 seconds - need to improve user experience during wait
+- **Quality Consistency**: Ensuring generated avatars maintain consistent quality across different inputs

+You are an expert research analyst for a high-end podcast production team. 
+Your task is to analyze the following research data and extract deep, actionable insights for a podcast episode.
+
+PODCAST CONTEXT:
+Topic: {request.topic}
+{bible_context}
+{analysis_context}
+
+RESEARCH DATA (from {len(sources)} sources):
+{raw_content}
+
+TASK:
+1. Provide a comprehensive summary (2-3 paragraphs) of the most important findings. Use Markdown for formatting (bolding, lists).
+2. Extract 3-5 "Key Insights". Each insight should have a title and a detailed explanation.
+3. For each insight, identify which source indices (e.g. 1, 2) it was derived from.
+4. Extract notable "Expert Quotes" - direct quotes from industry leaders, researchers, or authoritative voices found in the sources.
+5. Suggest 2-4 "Listener CTA" (call-to-action) ideas that the podcast host can use to engage the audience.
+6. Identify 3-5 "Mapped Angles" - unique content angles with rationale for why they matter for this topic.
+
+NOTE: The research data includes "Key Highlights", "Summaries", and "Excerpts" from various sources. 
+Pay special attention to the "Key Highlights" sections as they contain the most relevant information extracted by the neural search engine.
+
+Return JSON structure:
+{{
+  "summary": "Detailed markdown summary...",
+  "key_insights": [
+    {{
+      "title": "Insight Title",
+      "content": "Detailed markdown content...",
+      "source_indices": [1, 2]
+    }}
+  ],
+  "expert_quotes": [
+    {{
+      "quote": "Exact quote from source...",
+      "source_index": 1
+    }}

+  "listener_cta": [

+      "why": "Why this angle matters for the audience...",
+      "mapped_fact_ids": ["fact_1", "fact_2"]
+    }}
+  ]
+}}
+
+Requirements:
+- Ensure insights are deep, not just superficial facts. Look for trends, expert opinions, and specific data points.
+- Expert quotes should be exact or near-exact quotes from the sources, with attribution.
+- Listener CTAs should be practical and engaging (e.g., "Share your experience with X on social media").
+- Mapped angles should be unique perspectives that make the episode stand out.
+- Tone should be professional, insightful, and ready for a podcast host to discuss.
+- Avoid generic filler.

+# Agent Flat-File Context System Review
+
+## Scope
+This review documents the **current implementation** of ALwrity's onboarding flat-file context system and compares it to the proposed **Direct-to-File Virtual Shell (VFS)** model.
+
+---
+
+## 1) Present Implementation (What Exists Today)
+
+### 1.1 Storage model
+- Context is stored per user under:
+  - `backend/workspace/workspace_<safe_user_id>/agent_context/`
+- Files are JSON documents, one per onboarding domain:
+  - `step2_website_analysis.json`
+  - `step3_research_preferences.json`
+  - `step4_persona_data.json`
+  - `step5_integrations.json`
+  - `context_manifest.json`
+
+### 1.2 Writer and reader
+- `AgentFlatContextStore` is the core component that:
+  - sanitizes user IDs for path safety,
+  - writes documents atomically (`tempfile` + `os.replace`),
+  - sets restrictive file permissions (`0600` best effort),
+  - generates structured `agent_summary` objects,
+  - updates a manifest index of available documents.
+- Data is loaded by direct file reads from the same class (`load_stepX_context_document`).
+
+### 1.3 Read-path fallback chain
+`SIFIntegrationService` uses a strict fallback sequence for onboarding context retrieval:
+1. **flat file** (`AgentFlatContextStore`)
+2. **database** (`WebsiteAnalysis`, `ResearchPreferences`, `PersonaData`, etc.)
+3. **SIF semantic index** (`TxtaiIntelligenceService.search`)
+
+Step 5 uses `flat_file -> sif_semantic`.
+
+### 1.4 Producer flow (onboarding persistence)
+`StepManagementService` persists canonical snapshots to flat context when onboarding steps are saved:
+- Step 2 website analysis
+- Step 3 research preferences (and later competitor-enriched refresh)
+- Step 4 persona data
+- Step 5 integrations
+
+### 1.5 Context optimization currently implemented
+- Sensitive-key redaction in nested payloads (`api_key`, `token`, `secret`, etc.).
+- Size budgeting with trimming (`DEFAULT_MAX_BYTES = 300_000`) and trim metadata.
+- Generated summaries include:
+  - quick facts,
+  - retrieval hints (high-signal terms and suggested agent queries),
+  - domain-specific focus blocks.
+- Document context includes audience, retrieval contract, journey stage, related documents, and context-window guidance.
+
+---
+
+## 2) Comparison vs Proposed Direct-to-File VFS
+
+## Strong alignment
+The current system already matches the proposal in important ways:
+- **Direct-to-file persistence** instead of DB-backed retrieval for fast reads.
+- **Manifest/index concept** (`context_manifest.json`) that can act like a precomputed path map.
+- **Agent-first retrieval semantics** (summary-first contract and fallback policy).
+- **Operational safety controls** (atomic writes, redaction, path sanitization).
+
+## Gaps vs full virtual shell abstraction
+The following pieces are not fully implemented as described in your proposed architecture:
+- No explicit **virtual shell provider** (`IFileSystem`) exposing `ls/cat/grep/find` commands.
+- No always-live, process-level **in-memory `Map<virtualPath, absolutePath>`** for path lookups.
+- No native glob/query command layer for agent shell UX.
+- Not currently **read-only enforced at API surface** (writes are intentionally allowed by onboarding services to refresh context).
+
+---
+
+## 3) Practical Recommendation: Incremental VFS Evolution
+
+1. **Introduce a read-only VFS facade for agents**
+   - Keep `AgentFlatContextStore` as the write path for trusted onboarding services.
+   - Add `AgentContextVFS` read adapter exposing:
+     - `ls(path)` from manifest,
+     - `cat(path)` mapped to underlying JSON,
+     - `find(glob)` on virtual keys,
+     - `grep(query)` with path prefilter + stream scan.
+
+2. **Promote manifest to a first-class path map**
+   - Build and cache an in-memory map on service startup or first access.
+   - Refresh map when manifest `updated_at` changes.
+
+3. **Add explicit write policy boundaries**
+   - Agent-facing interface: hard read-only (`EROFS`).
+   - Internal system service interface: allow writes for onboarding synchronization.
+
+4. **Metadata strategy for grep ranking**
+   - Prioritize in order:
+     1) `agent_summary.quick_facts`
+     2) `agent_summary.retrieval_hints.high_signal_terms`
+     3) `document_context.context_type` and `journey.stage`
+     4) full `data` body
+
+---
+
+## 4) Response to the Metadata Header Question
+
+> "Does your current `.txt` optimization include specific metadata headers (like YAML frontmatter) that the grep tool should prioritize?"
+
+For this implementation, context is currently persisted as structured JSON (not `.txt` with YAML frontmatter). Equivalent high-value metadata already exists and should be prioritized for search/ranking:
+- `context_type`
+- `updated_at`
+- `agent_summary.quick_facts`
+- `agent_summary.retrieval_hints.high_signal_terms`
+- `document_context.journey.stage`
+- `document_context.related_documents`
+
+If you later move to `.txt` transport files, mirror these as frontmatter fields to preserve retrieval quality.
+
+---
+
+## 5) Bottom line
+Your current onboarding flat-file context implementation is already a strong "shim" architecture and close to the proposed model. The biggest missing piece is a dedicated virtual-shell read interface (`ls/cat/grep/find`) backed by a persistent path-map cache and a clear read-only contract for agent execution contexts.
+
+---
+
+## 6) Implemented Follow-up (VFS Adapter + Workspace Guide)
+
+The following enhancements are now implemented:
+
+1. **Auto-generated workspace map**
+   - The system now generates `workspace_<user>/README.md` whenever `context_manifest.json` is updated.
+   - The README includes:
+     - available context files,
+     - key signal hints from `agent_summary.retrieval_hints.high_signal_terms`,
+     - journey-stage hints,
+     - virtual path mappings and retrieval strategy guidance.
+
+2. **Read-only VFS facade**
+   - Added `AgentContextVFS` with:
+     - `list_context()` (`ls` equivalent),
+     - `search_context()` (`grep` equivalent; prioritizes `high_signal_terms` and `quick_facts`),
+     - `read_context_file()` (`cat` equivalent; large-file summary mode + subkey drilldown),
+     - explicit write rejection (`EROFS`).
+
+3. **Virtual path support**
+   - `/env/summary` maps to `AgentFlatContextStore.generate_total_summary()`.
+   - `/steps/website`, `/steps/research`, `/steps/persona`, `/steps/integrations` map to step documents.
+
+4. **System-prompt helper**
+   - Added `build_filesystem_header(user_id)` to inject a compact file availability + priority hint block into agent startup prompts.
+
+5. **Merged context helper in SIF integration**
+   - `SIFIntegrationService.get_merged_flat_context()` now provides a unified view across all available flat files while preserving existing per-step retrieval methods.
+
+6. **Basic file-level security hardening**
+   - Workspace and context directories are now explicitly forced to `0700`.
+   - Context and workspace files are written with strict `0600`.
+   - Added path sandboxing to ensure requested paths cannot escape user workspace roots.
+   - Restricted context-file loading to an allowlist of known onboarding context documents.
+   - Added deterministic per-user secret derivation from `.env` (`FILE_ENCRYPTION_SALT` + `safe_user_id`) with non-sensitive fingerprints for audit/debug and future encryption-at-rest rollout.
+
+7. **Tool-logic enhancement (coarse-to-fine search)**
+   - `search_context` now performs a two-pass retrieval:
+     1) high-relevance summary match pass (`high_signal_terms`, `quick_facts`),
+     2) parallelized stream scan pass over sandboxed allowlisted files for supporting details.
+   - Results include relevance labels, snippets, and line numbers for body matches.
+   - Large-result behavior now reports truncation guidance (show top 10 and suggest narrower keywords).
+   - `inspect_file` now provides token-saving behavior: full return for small files, or `agent_summary` + top-level keys for larger files, with key-level zoom-in support.
+
+8. **Retrieval robustness roadmap (next hardening phase)**
+   - **Query normalization:** Add synonym expansion and typo-tolerant matching (e.g., `tone` ≈ `brand voice`) before coarse/fine passes.
+   - **Confidence scoring:** Return confidence tiers that blend source freshness (`updated_at`), summary-match strength, and match density.
+   - **Field-aware boosting:** Weight matches by field priority (`high_signal_terms` > `quick_facts` > `data`) and document recency.
+   - **Deduplicated evidence:** Collapse repeated hits from the same file/key into one clustered result with a single best snippet and hit count.
+   - **Fallback query reformulation:** If zero hits, automatically retry with narrow/expanded variants and return attempted queries.
+   - **Answerability contract:** Add a lightweight `can_answer` signal in search responses so orchestrators can decide whether to ask follow-up questions or fetch more context.
+   - **Evaluation harness:** Track retrieval metrics over golden queries (`precision@k`, `MRR`, zero-hit rate, stale-hit rate) in CI to prevent relevance regressions.
+
+9. **Collaborative VFS namespace (shared memory mode)**
+   - Added optional `project_id` support to `AgentContextVFS` with isolated root: `workspace/project_<project_id>/`.
+   - Introduced `scratchpad/` for collaborative writes while keeping onboarding `agent_context` read-first.
+   - Added `write_shared_note(...)` with advisory locking (`flock`) and strict filename/path validation.
+   - Added append-only `activity_log.jsonl` via `append_activity_log(...)` for watchdog/event-driven coordination.
+   - Maintains owner-only permissions (`0700` scratchpad dir, `0600` files) and audit trails for shared writes.
+
+10. **Testing readiness upgrades**
+   - Added automated tests for:
+     - query reformulation + `can_answer` behavior in `search_context`,
+     - large-file progressive disclosure behavior in `inspect_file`,
+     - collaborative write path (`write_shared_note`) and append-only activity logging.
+   - Test module: `backend/tests/test_agent_context_vfs.py`.
+   - These tests provide a baseline regression harness for VFS retrieval quality and shared-memory safety.
+
+11. **Static + Structural retrieval hardening**
+   - Added a **static triage layer** in `search_context`:
+     - keyword-density scoring,
+     - `low_probability` flags for likely-noisy hits,
+     - `triage_top5` shortlist for router-style pre-filtering.
+   - Added `read_struct(filename, path_query)`:
+     - resolves dot/bracket JSON paths to return node-level data only,
+     - includes lightweight dependency injection (e.g., Step 4 persona reads include Step 2 brand voice context when available),
+     - keeps output token-efficient for downstream agents.

 Provides Google Trends data integration for the Research Engine.
 Handles rate limiting, caching, error handling, and data serialization.
 
+Key design decisions:
+- Monkey-patches urllib3 Retry to fix method_whitelist→allowed_methods (urllib3 2.x)
+- Monkey-patches pytrends related_topics/related_queries to catch IndexError bug
+- Uses TrendReq built-in retries (3 retries, 1s backoff) for automatic 429 handling
+- Random user-agent rotation per instance to reduce fingerprinting
+- 1-second delays between sequential requests to respect rate limits
+- 24-hour in-memory cache to avoid redundant API calls
