Wiki Status — Audit & Delta

You are computing the current state of the wiki: what's been ingested, what's new since last ingest, and what the delta looks like. This helps the user decide whether to append (ingest the delta) or rebuild (archive and reprocess everything).

Before You Start

1. Read .env to get OBSIDIAN_VAULT_PATH, OBSIDIAN_SOURCES_DIR, CLAUDE_HISTORY_PATH, CODEX_HISTORY_PATH
2. Read .manifest.json at the vault root — this is the ingest tracking ledger

The Manifest

The manifest lives at $OBSIDIAN_VAULT_PATH/.manifest.json. It tracks every source file that has been ingested. If it doesn't exist, this is a fresh vault with nothing ingested.

Step 1: Scan Current Sources

Build an inventory of everything available to ingest right now:

Documents (from OBSIDIAN_SOURCES_DIR)

Glob each directory in OBSIDIAN_SOURCES_DIR for all text files
Record: path, size, modification time
