Unify token tracking, smart links, and personality settings across admin and chat.

Add centralized token budget accounting with bonus tokens, sync buy URLs to the links table, wire response_style into prompts, block suspended authors, and add a 25-test suite.

+# Author RAG — Master Test Plan
+
+**Version:** 1.0  
+**Date:** 2026-06-19  
+**Status:** Active — pre-implementation baseline  
+**Owner:** Engineering  
+**Scope:** Full platform — SuperAdmin, Author Admin, Widget/Chat, RAG pipeline, analytics, notifications
+
+---
+
+## 1. Purpose & Goals
+
+This document defines the complete verification strategy for Author RAG before any feature is considered production-ready. The platform's success depends on **100% consistency** across:
+
+- Token accounting (single source of truth, enforced everywhere)
+- Conversion UX (Buy Book CTA visible when configured and appropriate)
+- Human tone (no robotic fallbacks; personality settings honored)
+- Role isolation (SuperAdmin, Author, Visitor)
+- Analytics integrity (every turn tracked; failures never break chat)
+
+### 1.1 Known Critical Gaps (must pass after fix)
+
+| ID | Gap | Impact | Primary Files |
+|----|-----|--------|---------------|
+| G-01 | `client_access.tokens_used` never incremented on chat | Admin & SuperAdmin show 0% usage | `tracker.py`, `admin/router.py`, `superadmin_service.py` |
+| G-02 | Redis `tokens:{author_id}:current` incremented but never read | Parallel orphan counter | `tracker.py`, `subscription.py` |
+| G-03 | `budget_exhausted:{author_id}` never set | Budget enforcement non-functional | `subscription.py`, `tracker.py` |
+| G-04 | Admin `token-usage` ignores `bonus_tokens`; embed-token includes them | Inconsistent UI numbers | `admin/router.py` |
+| G-05 | Smart Links save to `books.buy_url`; chat reads `links.purchase_url` | Buy Book button never appears | `admin/router.py`, `rag_pipeline.py`, `link_repo.py` |
+| G-06 | `response_style` saved but not injected into prompts | Personality page is cosmetic | `prompter.py`, `rag_pipeline.py` |
+| G-07 | Default fallback contains robotic phrase filtered by hack | Inconsistent fallback behavior | `rag_pipeline.py`, `user.py` |
+| G-08 | `chatbot_is_active` not checked on chat | Suspended authors still chat | `subscription.py`, `chat.py` |
+| G-09 | Token warning emails use placeholder `tokens_used=0` | Alerts never fire | `tasks/` |
+| G-10 | No automated tests; CI runs `pytest \|\| true` | Regressions undetected | `.github/workflows/ci.yml` |
+

+## 4. Test Suites
+
+### Suite A — Token Usage Consistency (P0 — BLOCKING)
+
+**Objective:** One canonical token counter drives enforcement, admin UI, SuperAdmin UI, emails, and exports.
+
+#### A.1 Single Source of Truth
+
+| Test ID | Scenario | Steps | Expected |
+|---------|----------|-------|----------|
+| A-01 | Chat increments `tokens_used` | Send 1 chat message with known token usage (mock OpenAI returns `prompt_tokens=100, completion_tokens=50`) | `client_access.tokens_used` += 150 |
+| A-02 | Chat increments Redis counter | Same as A-01 | `tokens:{author_id}:current` += 150 |
+| A-03 | Counters stay in sync | Send 10 messages | `tokens_used` == Redis counter == sum of `chat_messages` tokens for period |
+| A-04 | Regeneration counts tokens | Hallucination triggers regen (2 LLM calls) | Both calls' tokens counted |
+| A-05 | Custom Q&A path counts tokens | Message hits custom Q&A override | Tokens still recorded if LLM called |
+| A-06 | Failed LLM does not increment | OpenAI timeout / 500 | No token increment; error logged |
+| A-07 | Analytics failure does not block chat | Mock DB write failure in `track_turn` | Visitor gets response; error logged at ERROR |
+
+#### A.2 Budget Math (must be identical everywhere)
+
+| Test ID | Formula Under Test | Surfaces |
+|---------|-------------------|----------|
+| A-10 | `total_budget = token_budget + bonus_tokens` | SuperAdmin grants, embed-token |
+| A-11 | `remaining = total_budget - tokens_used` | Admin token page, embed-token, SuperAdmin |
+| A-12 | `percent_used = tokens_used / total_budget * 100` | Admin gauge, SuperAdmin progress bar |
+| A-13 | Bonus tokens increase remaining without changing expiry | SuperAdmin bonus modal |
+
+**Consistency matrix (all must match after each chat turn):**
+
+| Surface | Endpoint / Store | Includes Bonus? | Reads `tokens_used`? |
+|---------|------------------|-----------------|----------------------|
+| Author Token Usage page | `GET /api/admin/{slug}/token-usage` | MUST | MUST |
+| Author Embed Token card | `GET /api/admin/{slug}/embed-token` | MUST | MUST |
+| SuperAdmin Token Management | `GET /api/super/grants` | MUST | MUST |
+| SuperAdmin Platform Analytics | `GET /api/super/health` or analytics | MUST | MUST |
+| Subscription validation | `validate_subscription_token` | MUST | MUST |
+| Analytics export CSV | `GET /api/admin/{slug}/export/analytics` | N/A (historical) | Aggregated from events |
+| Weekly digest email | Celery task | MUST | MUST |
+
+#### A.3 Budget Enforcement
+
+| Test ID | Scenario | Expected |
+|---------|----------|----------|
+| A-20 | Usage at 79% | Chat works normally |
+| A-21 | Usage at 80% | Warning email sent (if `notify_token_alerts=true`) within 60s |
+| A-22 | Usage at 99% | Chat still works; UI shows red/warning state |
+| A-23 | Usage at 100% | `budget_exhausted:{author_id}` set; next message returns graceful fallback (HTTP 200 per BDD), OpenAI NOT called |
+| A-24 | SuperAdmin adds bonus at 100% | `budget_exhausted` cleared; chat resumes |
+| A-25 | SuperAdmin reset tokens | `tokens_used=0`; policy on `bonus_tokens` documented and tested |
+| A-26 | Extend subscription at 100% usage | Expiry extended; usage NOT reset unless explicitly reset |
+
+#### A.4 SuperAdmin Token Operations
+
+| Test ID | Action | Verify |
+|---------|--------|--------|
+| A-30 | Grant new subscription | `token_budget` set per plan; `tokens_used=0` |
+| A-31 | Add bonus tokens | `bonus_tokens` incremented; audit log entry |
+| A-32 | Reset token usage | `tokens_used=0`; Redis counters cleared; audit log |
+| A-33 | Revoke subscription | Chat blocked (403); Redis blacklist set |
+| A-34 | Token Management UI totals | Sum of all grants' `tokens_used` matches platform aggregate |
+
+#### A.5 Author Admin Token Page
+
+| Test ID | Scenario | Expected |
+|---------|----------|----------|

+
+### Suite B — Buy Book Button & Smart Links (P0 — BLOCKING)
+
+**Objective:** When an author configures a purchase URL, the widget shows a "Buy Book" button at the correct times.
+
+#### B.1 Data Model Unification
+
+| Test ID | Scenario | Expected |
+|---------|----------|----------|
+| B-01 | Author saves Smart Link (`PUT /smart-links/{bookId}`) | `links.purchase_url` AND `books.buy_url` both set (or single source with fallback read) |
+| B-02 | Author sets buy URL on book upload | URL persisted and available to chat |
+| B-03 | `_get_book_links()` with only `books.buy_url` | Returns purchase URL (fallback) |
+| B-04 | `_get_book_links()` with only `links` row | Returns purchase URL |
+| B-05 | Preview URL | "Read Preview" button appears when configured (max 2 links) |
+
+#### B.2 Upsell Engine — When Button Appears
+
+| Test ID | Intent / Context | Turn | Expected `show_link` |
+|---------|------------------|------|----------------------|
+| B-10 | `purchase_intent` ("Where can I buy?") | 1 | `true` + Buy Book button in widget |
+| B-11 | `full_story_request` | any | `true` |
+| B-12 | `question`, book selected | 2+ | `true` (per `should_include_link`) |
+| B-13 | `question`, high interest (≥0.45) | 2+ | `true` |
+| B-14 | `complaint` | any | `false` — no buy button |
+| B-15 | `greeting` | 1 | `false` (RECIPROCITY only, no button) |
+| B-16 | Strategy `DIRECT_CTA` | any | `true` |
+| B-17 | No purchase URL configured | any | `false` — no empty/broken button |
+| B-18 | `show_link=true` but URL is `#` | any | Button must NOT render (invalid URL guard) |
+
+#### B.3 Widget Rendering
+
+| Test ID | Scenario | Expected |
+|---------|----------|----------|
+| B-20 | API returns `links: [{label:"Buy Book", url:"https://...", type:"purchase"}]` | Widget renders `<a class="ab-link-btn">` with icon |
+| B-21 | Click Buy Book | `POST /track-click` fired with correct `session_id`, `book_id`, `link_type` |
+| B-22 | Farewell on widget close | `POST /session/farewell` returns text + Buy Book link if URL exists |
+| B-23 | Max 2 links | Purchase + Preview shown; no third link |
+| B-24 | Mobile viewport (375px) | Buttons wrap correctly, tappable (min 44px touch target) |
+| B-25 | `target="_blank" rel="noopener"` | Present on all link buttons |
+
+#### B.4 End-to-End Conversion Path
+
+| Test ID | Flow | Expected |
+|---------|------|----------|
+| B-30 | Configure URL → chat "where can I buy" → click button | Analytics records `link_shown=true` on message + click event |

+
+## 5. Cross-Cutting Consistency Checklist
+
+Run this checklist after **every** release candidate:
+
+### 5.1 Numeric Consistency
+
+- [ ] Send exactly 1 chat message with known token count
+- [ ] Verify `client_access.tokens_used`
+- [ ] Verify Redis `tokens:{author_id}:current`
+- [ ] Verify Author Admin → Token Usage page
+- [ ] Verify Author Admin → Embed Token card
+- [ ] Verify SuperAdmin → Token Management row
+- [ ] Verify SuperAdmin → Platform Analytics total
+- [ ] Verify `chat_messages` sum for session
+- [ ] Verify `analytics_events` row for turn
+
+### 5.2 Buy Button Consistency
+
+- [ ] Configure buy URL in Smart Links
+- [ ] Ask "where can I buy this book?"
+- [ ] Confirm `link_shown=true` in DB
+- [ ] Confirm button visible in widget DOM
+- [ ] Click button → analytics event recorded
+- [ ] Close widget → farewell shows Buy Book
+
+### 5.3 Tone Consistency
+
+- [ ] Set personality to `casual` → verify prompt
+- [ ] Trigger no-context path → no robotic phrases
+- [ ] Trigger hallucination fallback → warm safe message
+- [ ] Verify no markdown in any response path
+
+---
+
+## 6. Edge Case Catalog
+
+| Category | Edge Case | Expected Behavior |
+|----------|-----------|-------------------|
+| **Tokens** | Author with 0 budget grant | Clear error on grant; chat blocked |
+| **Tokens** | Multiple rapid messages | Atomic increment; no lost counts |
+| **Tokens** | Month rollover | Usage resets per billing period (define policy) |
+| **Tokens** | SuperAdmin reset during active chat | Next message uses fresh budget |
+| **Links** | URL with UTM params | Preserved exactly |
+| **Links** | International domain (IDN) | Validated and stored |
+| **Links** | HTTP vs HTTPS | HTTPS preferred; mixed content warning in admin |
+| **Books** | 0 active books | Catalog setup message |
+| **Books** | 50+ books | Selector pagination / scroll |
+| **Chat** | Empty message | 400 validation error |
+| **Chat** | 2000+ char message | Truncated or rejected gracefully |
+| **Chat** | Unicode / emoji | Handled end-to-end |
+| **Chat** | RTL language input | Widget displays correctly |
+| **Session** | Same fingerprint, new session | Separate session IDs |
+| **Auth** | Token refresh during admin action | Seamless retry |
+| **Upload** | Duplicate SHA-256 | Skip/replace dialog |
+| **Upload** | Network drop mid-upload | Resume from chunk (if implemented) |
+
+---
+
+## 7. Acceptance Criteria (Definition of Done)
+
+A feature or fix is **DONE** only when:
+
+1. All P0 tests in the relevant suite pass in CI
+2. No new gaps introduced in the consistency matrix (Section 5)
+3. BDD scenario added to `tests/bdd/features/` BEFORE merge (per `.agent/RULES.md`)
+4. Unit test coverage ≥80% on touched modules
+5. Manual smoke on staging: Author flow + Visitor flow + SuperAdmin flow
+6. Audit log entry verified for every SuperAdmin mutation
+7. Analytics event verified for every chat turn
+8. Documentation updated if API contract changes
+
+### Release Blockers (cannot ship if any fail)
+
+- [ ] Suite A — all P0 tests green
+- [ ] Suite B — all P0 tests green
+- [ ] Suite C — all P0 tests green
+- [ ] Suite D — D-10, D-11, D-30, D-31 green
+- [ ] CI no longer uses `|| true`
+
+---
+
+## 8. Implementation Roadmap for Test Infrastructure
+
+### Phase 1 — Foundation (Week 1)
+
+1. Create `tests/conftest.py` with async DB, Redis, JWT helpers
+2. Add factories: `UserFactory`, `ClientAccessFactory`, `BookFactory`, `LinkFactory`
+3. Mock OpenAI client fixture returning deterministic token counts
+4. Fix CI: remove `|| true`; add PostgreSQL + Redis services
+
+### Phase 2 — P0 Unit Tests (Week 1–2)
+
+1. `test_token_tracking.py` — Suite A
+2. `test_upsell_engine.py` — Suite B (link logic)
+3. `test_formatter.py` — link injection, max links
+4. `test_prompter_personality.py` — Suite C
+5. `test_subscription_validation.py` — Suite D
+
+### Phase 3 — Integration Tests (Week 2–3)
+
+1. `test_chat_api.py` — full message flow with mocked LLM
+2. `test_admin_token_usage.py` — API response consistency
+3. `test_superadmin_grants.py` — grant/bonus/reset flows
+4. `test_smart_links_sync.py` — books ↔ links unification
+
+### Phase 4 — BDD & E2E (Week 3–4)
+
+1. Port `.agent/BDD_SPECS.md` → `tests/bdd/features/*.feature`
+2. Playwright: widget buy button visible + click
+3. Playwright: admin token gauge updates after chat
+
+### Phase 5 — Hardening (Ongoing)
+
+1. Synthetic production monitor: health + token math spot-check
+2. Load test: 60 req/min rate limit boundary
+3. Chaos: Redis restart during chat
+
+---
+
+## 9. Traceability Matrix
+
+| User-Reported Issue | Test Suite | Test IDs |
+|--------------------|------------|----------|
+| Tokens not counted on admin | A | A-01, A-40, A-43 |

+| Robotic tone | C | C-10, C-11, C-01–C-05 |
+| Buy now button not in chat | B | B-01, B-10, B-20, B-30 |
+| Personality settings ignored | C | C-01–C-05 |
+| Budget not enforced | A | A-20–A-26 |
+| Inconsistent token numbers | A | A-10–A-13, Section 5.1 |
+

+
+## 10. Sign-Off
+
+| Role | Name | Date | Signature |
+|------|------|------|-----------|
+| Engineering Lead | | | |
+| QA | | | |
+| Product | | | |
+
+---
+
+*This plan should be treated as a living document. Update version and traceability matrix whenever gaps G-01 through G-10 are resolved or new features are added.*

+## Summary
+
+| Metric | Value |
+|--------|-------|
+| **Total tests** | 25 |
+| **Passed** | 25 |
+| **Failed** | 0 |
+| **Pass rate** | 100% |
+

+
+## Fixes Applied
+
+| Gap | Fix |
+|-----|-----|
+| G-01 Token counting | `record_token_usage()` updates `client_access.tokens_used` + Redis |
+| G-03 Budget enforcement | Sets `budget_exhausted:{author_id}` at 100% usage |
+| G-04 Token math | Unified via `app/services/token_budget.py` (includes bonus_tokens) |
+| G-05 Buy Book URLs | Smart links sync to `links` table; `_get_book_links()` falls back to `books.buy_url` |
+| G-06 Personality | `{response_style}` + tone instructions in `MASTER_SYSTEM_PROMPT` |
+| Tracker import | `ChatMessage` imported from `app.models.chat_session` |
+| Complaint upsell | No buy link on `complaint` intent |
+| Suspension | `chatbot_is_active` checked in subscription validation |
