# Lefevre EPUB3 Validation

Date: 2026-05-14

## Source

Local source file:

`/mnt/c/Users/bernd.worsch/Downloads/LefevreEdwin-ReminiscencesOfAStockOperator.epub`

The EPUB is Project Gutenberg edition 60979, EPUB package version 3.0. The OPF
metadata identifies:

- title: `Reminiscences of a Stock Operator`
- creator: `Edwin Lefevre`
- subjects: `Speculation`, `New York Stock Exchange`, `Investments`
- rights: public domain in the USA

## Current Infrastructure Result

The current generic generator can initialize a disposable infospace from the
file and run non-provider metrics:

- disposable root:
  `/tmp/infospace-bench-lefevre-583mopy_/infospaces/reminiscences-stock-operator`
- source chunks: 155
- entities: 0
- relations: 0
- evaluations: 0
- stale status: false
- metrics snapshot: `5978ece0`

The source-only metrics were:

- redundancy ratio: `0.9225806451612903`
- coverage ratio: `1.0`
- coherence components: `155.0`
- consistency cycles: `0.0`
- granularity entropy: `-0.0`

## Findings

The EPUB intake works mechanically, but it is not ready for a serious full-book
OpenRouter generation run.

- EPUB spine order is visible in `OEBPS/content.opf`, but current intake reads
  XHTML files by archive-name sorting.
- Current titles mostly collapse to the same long Gutenberg page title instead
  of chapter labels such as `I`, `II`, and `III`.
- Current intake includes non-body material such as cover/header/footer/license
  candidates unless the caller manually filters after import.
- `generate plan` is not yet a compact cost/risk plan for a long book; a full
  all-stage run would imply hundreds of provider calls.
- Resume state is run-level enough for the small generic path, but a long ebook
  needs chunk-level retry, stale, and skip policy.
- Cross-chunk entity deduplication and merge/review policy are needed before a
  full narrative book becomes a coherent infospace.

## Desired Readiness Bar

Before building the real Lefevre infospace with OpenRouter, the CLI should be
able to show:

- book metadata and selected source sections
- body-only chapter order
- stable chapter/chunk IDs
- estimated provider call count and token/cost budget
- selected chapter or chunk filters for smoke runs
- deterministic fixture acceptance on a small Lefevre-like subset
- optional live one-chapter smoke run with explicit provider/model/cost caps
