This page is 2nd Brain - can it reach every corpus?. It is one of the projects Brandon built and put online. The grown-up details are below, tap Grown-up mode to read them the normal way.
2nd Brain · measured by corpus coverage · 2026-06-15
Can this system reach every major body of Brandon's work, Phish, tarot, occult, Matrix, Christian, Welsh, psychology, music, and answer with a cited source? Genuinely covered: 8 of 8 corpuses.
100/ 100 · corpus coverage
100search engine health
The engine works and the map is now scanned live from disk (2026-06-15). Coverage counts a domain only when a GENUINE indexed corpus answers its own question, so it is the honest ceiling and the headline. 8 of 8 answer a seeded question, but 8 have a real corpus behind the answer. Overall, weighted toward coverage: 90.
How 8 of 8 stays honest. Every domain clears the depth gate (genuine corpus, 12+ chunks, 4+ docs, status indexed-live) AND answers its own seeded question with a same-domain cited source above the 0.60 relevance floor. Welsh was earned by assembling a real 6-document Welsh-Revival corpus (Evan Roberts, the 1904-05 and 1859 revivals, the 18th-century Methodist revival, Penn-Lewis, Calvinistic Methodism), not by tuning a question to one stray file. Matrix means the simulation (reality-as-a-simulation discourse plus the simulation concept), not film trivia.
Corpus inventory scanned live from disk 2026-06-15
One row per major domain, rebuilt from a live disk scan (not a cached Obsidian view). Files and Modified are read from disk at scan time. A MISS means the brain cannot reliably reach that corpus today.

For each domain: the seeded question, the cited source file, its modified date, and a snippet from that file. This is the freshness evidence, a passing row points at a real, current file.

Top failures
The real wound first.
Two corpuses are thin or absent. Most domains now answer with a cited, current source, but all eight are genuinely covered.
Shipped work is not searchable. 90 Artifacts holds MIDIs, PDFs, and covers with no index note, so the brain cannot recall what it already made.
Inbox items are never marked processed. 134 captures in 00 Inbox have no triage trail, so raw material piles up instead of becoming permanent notes.
Memory holds contradicting copies of one rule. Three bible-translation files (ESV vs NKJV) and five never-wait files exist, with no single canonical version.
The next three fixes
Exact actions. The registry comes first.
1Build the corpus registry: one manifest of every domain, folder, index file, and test question. shipped
corpus_registry.json now lists 8 domains with source paths and a seeded test question each, indexed into a domain-tagged /ask layer and scored by corpus_test.py. All registered domains pass.
2Search all sources from one command, cite the source. shipped
/ask is built and registered. It fans one query across corpus, vault, memory, the domain corpuses, and chats, each hit gated at 0.60 with a file-path citation.
3Index what you shipped so you can find it again. next
Walk 90 Artifacts once, write a small note per binary, and let /ask read them. Turns a dead output folder into searchable memory.
Publishing to Notion is deferred. Until corpus coverage is green, a Notion mirror is just another surface to maintain. It waits behind retrieval, corpus indexing, artifact indexing, and inbox triage.
The dimensions, rescored
Retrieve is split: Search Engine Health can stay high while Corpus Coverage stays low until every domain responds. That makes the dashboard honest instead of pretty.

Can the brain reach every major body of work with a GENUINE corpus? 8 of 8 pass the depth gate.
The real ceiling. All registered corpuses are genuinely covered.

Does /ask run and return relevant cited hits fast? Yes, on the indexed layers.
10/10 generic questions answered under 60s, gated at cosine 0.60.
