Health Debug — cabrain Brain Index & Taxonomy

Brain (namespace): healthdebug on cabrain (http://127.0.0.1:9310, MCP binary E:/Sites/ToGo/bin/brain-mcp.exe, agent healthdebug-agent). This file is the human-readable table of contents for what the brain stores and the classification convention every session must follow so memories stay easy to read and find. Last reorganized 2026-09-01.

How memories are classified

Every memory carries a metadata block with this schema:

The bucket field is metadata.type. cabrain's brain_details.types breakdown and the memory_recall types filter group by metadata.type. The domain type is not settable via a top-level type/memory_type field on retain or memory/edit (those are ignored and everything defaults to the bucket item) — it is read from metadata.type. So always set metadata.type to the category (we mirror the same value into category for clarity). Setting only category leaves the memory in the item bucket.

Writer convention (important): the retain API does not accept metadata. So every write is two steps: (1) retain the content, (2) memory/edit the returned id to attach the metadata block above (with type set). Give every memory a unique source_ref (writing several with the same source_ref makes each supersede the last). See [[cabrain-mcp-access]].

Categories

Category	What goes here
core-opinion	The two non-negotiable product opinions.
spec	Product/tech spec facts: stack, schema rules, colors, i18n, security model.
architecture-decision	Cross-cutting decisions (SSOT thin clients, one-plugin-per-engine, MCP surface).
protocol-engine	The 8 protocol engines and their parameters.
platform-plan	Per-surface PRDs (web, chrome, apple, android, desktop, mcp).
divergence	The five known legacy iOS/Android parity gaps.
plan-corpus	Plan index, phase sequence, current project status.
open-question	Decisions pending on Fady / design.
legacy-reference	Facts about the OLD codebase at E:\Sites\healthdebug (reference only).
secret-inventory	Inventory of legacy keys/credentials (values live in the secrets vault).
ops-deployment	Hosting, topology, supervisors, repo/infra facts.
session-handoff	Per-session build handoffs (see docs/plan/13-execution-modules-and-sessions.md).
brain-index	This meta record.

era/status let agents prefer current greenfield knowledge over superseded legacy facts. Stale/superseded legacy memories were down-weighted in importance so current knowledge ranks first.
