+
+### **3-Tier Caching Strategy**
+```
+Tier 1: Memory Cache (5-minute TTL)
+├── Fastest access
+├── Reduces database load
+└── Cache key: "active_strategy_{user_id}"
+
+Tier 2: Database Query with Activation Status
+├── Query StrategyActivationStatus table
+├── Get active strategy by user_id
+├── Include activation metadata
+└── Cache result in Tier 1
+
+Tier 3: Fallback Strategy
+├── Most recent strategy with comprehensive_ai_analysis
+├── Fallback to any strategy if needed
+├── Log warning for fallback usage
+└── Cache result in Tier 1
+```
+
+## 📊 **Database Integration**
+
+### **Active Strategy Query**
+```sql
+-- Query for active strategy using activation status
+SELECT sas.*, ecs.*
+FROM strategy_activation_status sas
+JOIN enhanced_content_strategies ecs ON sas.strategy_id = ecs.id
+WHERE sas.user_id = ? AND sas.status = 'active'
+ORDER BY sas.activation_date DESC
+LIMIT 1
+```
+
+### **Fallback Strategy Query**
+```sql
+-- Query for most recent strategy with comprehensive AI analysis
+SELECT *
+FROM enhanced_content_strategies
+WHERE user_id = ? AND comprehensive_ai_analysis IS NOT NULL
+ORDER BY created_at DESC
+LIMIT 1

+### Autofill: Learning, Personalization, and Explainability
+
+This document outlines next-step enhancements for Content Strategy Autofill focusing on: learning from user acceptances, industry presets, constraint-aware generation, explainability, and RAG-lite context. It also captures the trade-offs for sectioned generation vs single-call generation.
+
+## Goals
+- Increase accuracy, personalization, and trust without increasing UI complexity.
+- Keep costs predictable while reducing timeouts and retries.
+- Preserve user control: never overwrite locked/accepted fields without consent.
+
+## Single-call vs Sectioned Generation
+- Single-call (current):
+  - Pros: 1 AI request, simpler orchestration.
+  - Cons: Larger prompt, higher timeout risk, brittle for structured JSON, hard to pinpoint failures.
+- Sectioned (per category):
+  - Pros: Shorter prompts, better accuracy, quicker partial results, granular retries; lower latency per section; easier streaming (“Category X complete”).
+  - Cons: More calls; must cap/parallelize and cache to control cost.
+- Recommendation: Hybrid
+  - Default: single-call for fast baseline; fallback/option: sectioned generation for users with large sites or when single-call fails/times out.
+  - Implement a server flag `mode=hybrid|single|sectioned` and a per-user policy (feature flag).
+
+## Learning from Acceptances
+- Data we already persist: `content_strategy_autofill_insights` (accepted fields + sources/meta).
+- Learning policy:
+  - Build a per-user profile vector of “accepted values” and “field tendencies” (e.g., formats: video, cadence: weekly; brand voice: authoritative).
+  - During refresh:
+    - Use these as soft priors in prompt (“Bias toward previously accepted values unless contradictory to new constraints”).
+    - Prefer stable fields to remain unchanged unless explicitly unconstrained.
+- Storage additions:
+  - Add fields to `content_strategy_autofill_insights` meta: `industry`, `company_size`, `accepted_at`.
+  - Maintain a compact, cached user profile (derived) for prompt injection.
+- Safety:
+  - Respect locked fields (frontend lock) → never modified by refresh.
+
+## Industry Presets
+- Purpose: Cold-start quality boost.
+- Source: curated presets per industry, company size, and region.
+- Shape:
+  - Minimal key set aligned to core inputs (e.g., `preferred_formats`, `content_frequency`, `brand_voice`, `editorial_guidelines` template).
+- Retrieval:
+  - Endpoint: GET `/autofill/presets?industry=...&size=...&region=...` (cached).
+- Merge policy:
+  - Apply only to empty fields; AI may override if constraints request.
+
+## Constraint-Aware Generation
+- User constraints: budget ceiling, cadence/frequency, format allowlist, timeline bounds.
+- UI:
+  - “Constraints” panel (chip-set) accessible from header/Progress area.
+- Backend:
+  - Accept constraints in refresh request (query/body).
+  - Inject constraints into prompt header and soft-validate outputs.
+- Validation:
+  - Enforce with server-side validators; warn if AI violates, and auto-correct when safe.
+
+## Explain This Suggestion (Mini-modal)
+- Trigger: info icon next to each field.
+- Content:
+  - Short justification text (one or two sentences), sources (onboarding/RAG docs), confidence.
+  - No raw chain-of-thought; ask model for a concise rationale summary that’s safe to expose.
+- Backend payload additions:
+  - For each field: `meta[field] = { rationale: string, sources: string[] }` (optional).
+- Caution: redact sensitive content; keep rationale brief and non-speculative.
+
+## RAG-lite: Retrievable Context for Refresh
+- Context sources:
+  - Latest website crawl snippets (top pages, headings, meta), recent analytics top pages (if connected), competitor headlines if available.
+- Ingestion:
+  - Lightweight index (in-memory/SQLite) with page URL, title, summary; refresh on demand with TTL.
+- Prompt strategy:
+  - Provide 3–5 top relevant snippets per category; keep token budget small.
+- Controls:
+  - User toggle “Use live site signals” in refresh.
+
+## API Additions
+- Refresh
+  - GET `/autofill/refresh/stream?ai_only=true&constraints=...&mode=hybrid&use_rag=true`
+  - Non-stream POST variant mirrors params.
+- Presets
+  - GET `/autofill/presets?industry=...&size=...&region=...` → returns compact preset payload.
+- Acceptances (existing)
+  - POST `/{strategy_id}/autofill/accept` → persist accepted fields with transparency/meta.
+
+## UI Enhancements
+- Per-field lock and regenerate
+  - Lock prevents overwrite; Regenerate calls sectioned refresh for that field’s category.
+- Diff view on refresh
+  - Show before → after per field with accept/revert quick actions.
+- Constraints chips
+  - Visible summary in header; edit inline.
+- “Explain” modal
+  - Shows rationale and sources for the current value.
+
+## Observability & Metrics
+- Track per-field fill-rate, violation corrections, latency (per section), AI cost per refresh.
+- Alert on sudden drops in non-null field count or spike in violations/timeouts.
+
+## Rollout Plan
+1) Phase 1 (Low risk): presets + constraints + per-field lock, no sectioning.
+2) Phase 2: sectioned generation behind a feature flag; per-field regenerate.
+3) Phase 3: RAG-lite snippets and explain modal; start learning from acceptances in prompts.
+4) Phase 4: tune/fine-grain priors and add advanced validation rules per industry.
