Brain Resolver
Master decision tree for filing any new page. Walk this tree top-to-bottom. The first match wins. Every page has exactly one primary home.
Context: this brain is scoped to Cody Smith’s solo algo-trading work (CortanaROI MK2 + adjacent research). It does NOT track people, companies, deals, civic, or hiring - those directories are intentionally absent. If new domains emerge, add directories and resolvers here.
Decision Tree
Start here: what is the primary subject?
- Something being actively built - has code, a repo path, or active work
(scoring engine, position manager, dashboard feature, V2 subsystem) →
projects/ - A raw possibility - candidate strategy or engine idea nobody has started
yet →
ideas/ - A reusable mental model, framework, or thesis - 0DTE regime theory,
impulse signal design, climax-reversal pattern, drawdown math →
concepts/ - Prose - retrospectives, strategy essays, design docs, postmortems
that stand alone as a written artifact →
writing/ - Unsorted / quick capture - you are not sure yet →
inbox/ - Dead / superseded - no longer true, replaced by a newer page, or
retired subsystem →
archive/
Disambiguation Rules
- Concept vs. Idea: Could you teach it as a framework? Concept. Could you build it? Idea. Example: “regime detection theory” is a concept, “V3 flow-imbalance engine prototype” is an idea.
- Idea vs. Project: Is anyone (Cody, Codex, a cron) working on it? Yes → project. No → idea. The graduation moment is when work starts.
- Writing vs. Concept: Concepts are distilled (⇐ 200 words of compiled truth above the line). Writing is developed prose (an essay, a postmortem, a narrative). A one-pager on “why V1 bias has 0.1s half-life” is a concept. A 1500-word retrospective on the 2026-04-16 chop-day cluster is writing.
- Project vs. Writing: A project page tracks live state and open threads. A project writeup that stands alone as publishable prose (postmortem, retrospective, public blog post) goes in writing/ and links back to the project page.
- Concept vs. Writing: If it is a compact re-usable reference you would link from many other pages, it is a concept. If it is a narrative argument, it is writing.
Entity filing (slug format)
- Projects:
projects/<kebab-name>.md(e.g.,projects/v2-gex-regime-engine.md) - Concepts:
concepts/<kebab-name>.md(e.g.,concepts/climax-reversal-pattern.md) - Ideas:
ideas/<kebab-name>.md - Writing:
writing/<yyyy-mm-dd>-<kebab-title>.md - Inbox:
inbox/<yyyy-mm-dd>-<short-note>.md
The filename IS the identity. All cross-references use the slug.
Page structure (all domains)
Two layers separated by ---:
Above the line - Compiled Truth. One-paragraph summary. Structured State fields. Open Threads (active items, removed when resolved). See Also. Always current, always rewritten when new info arrives.
Below the line - Timeline. Append-only reverse-chronological evidence
log. Each entry: **YYYY-MM-DD** | Source - What happened.
See schema.md for templates.
MECE Check
Every page lands in exactly one directory. If something does not fit any
category, file in inbox/ and flag - that is a signal the schema needs
to evolve.
