-# AI Context Optimization Blueprint (v2.6)
+# AI Context Optimization Blueprint (v2.7)
 
 This blueprint outlines architectural improvements for how AI context is managed during the writing process. The goal is to provide the AI (Claude/Gemini) with **better, highly-targeted context upfront**, which will dramatically improve first-draft quality and reduce the reliance on expensive, time-consuming quality checks and rewrites (currently up to 5 attempts).

 1. ✅ **Frontend Action:** Added "Redo Book" form to `templates/consistency_report.html` footer with a text input for the revision instruction and a confirmation prompt on submit. *(Implemented v2.6)*
 2. ✅ **Backend Route:** Added `/project/<run_id>/revise_book/<book_folder>` route in `web/routes/run.py`. Route creates a new `Run` record and queues `generate_book_task` with the user's instruction as `feedback` and `source_run_id` pointing to the original run. The existing bible refinement logic in `generate_book_task` applies the instruction to the bible before regenerating. *(Implemented v2.6)*
 
+## 11. Series Continuity & Book Number Awareness (v2.7)
+
+**Current Problem:**
+The system generates books for a series, but the prompts in `story/planner.py` (specifically `enrich` and `plan_structure`) and the writing prompts do not explicitly pass the `series_metadata` (such as `is_series`, `series_title`, `book_number`, and `total_books`) to the LLM. The AI doesn't know if it's generating Book 1, Book 2, or Book 3, leading to inconsistent pacing and continuity across a series.
+
+**Solution & Implementation Plan:**
+1. ✅ **Planner Prompts Update:** Modified `enrich()` and `plan_structure()` in `story/planner.py` to extract `bp.get('series_metadata', {})` and inject a `SERIES_CONTEXT` block — "This is Book X of Y in the Z series" with position-aware guidance (Book 1 = establish, middle books = escalate, final book = resolve) — into the prompt when `is_series` is true. *(Implemented v2.7)*
+2. ✅ **Writer Prompts Update:** `story/writer.py` `write_chapter()` builds and injects the same `SERIES_CONTEXT` block into the chapter writing prompt and passes it as `series_context` to `evaluate_chapter_quality()` in `story/editor.py`. `editor.py` `evaluate_chapter_quality()` now accepts an optional `series_context` parameter and injects it into the evaluation METADATA so the editor scores arcs relative to the book's position in the series. *(Implemented v2.7)*
+
 ## Summary of Actionable Changes for Implementation Mode:
 1. ✅ Modify `writer.py` to filter `chars_for_writer` based on characters named in `beats`. *(Implemented in v1.5.0)*
 2. ✅ Modify `writer.py` `prev_content` logic to extract the *tail* of the chapter, not a blind slice. *(Implemented in v1.5.0 via `utils.truncate_to_tokens` tail logic)*

 8. ✅ **(v2.5)** Lore & Location RAG-Lite: `update_lore_index` in `bible_tracker.py`, `tracking_lore.json`, lore retrieval in `writer.py`, wired in `engine.py`. *(Implemented v2.5)*
 9. ✅ **(v2.5)** Structured Story State (Thread Tracking): new `story/state.py`, `story_state.json`, structured prompt context replacing raw summary blob in `engine.py`. *(Implemented v2.5)*
 10. ✅ **(v2.6)** "Redo Book" form in `consistency_report.html` + `revise_book` route in `run.py` that creates a new run with the instruction applied as bible feedback. *(Implemented v2.6)*
+11. ✅ **(v2.7)** Series Continuity Fix: `series_metadata` (is_series, series_title, book_number, total_books) injected as `SERIES_CONTEXT` into `story/planner.py` (`enrich`, `plan_structure`), `story/writer.py` (`write_chapter`), and `story/editor.py` (`evaluate_chapter_quality`) prompts with position-aware guidance per book number. *(Implemented v2.7)*
