Lefevre EPUB3 Validation

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
