Metabolic states

How notes are organized based on their activity level and volatility.

Term	Definition
Captive	Working notes with high-velocity, volatile intake. Lives in `00_Brain/Captive/`. Examples: Today.md, Week.md, Quarter.md
Periodic	Archived notes forming the permanent timeline. Lives in `00_Brain/Periodic/`. Examples: Daily/, Weekly/, Quarterly/
Semantic	Crystallized knowledge and reference material. Lives in `00_Brain/Semantic/`. Contains insights extracted from rituals
Synthetic	Active drafts and works in progress. Lives in `00_Brain/Synthetic/`. Contains observations being processed
Systemic	Infrastructure: templates, directives, coaching. Lives in `00_Brain/Systemic/`

See How Ada Works for detailed explanation.

Term	Definition
Skill	A Claude instruction set that performs a specific task. Lives in `.claude/skills/`
Ritual	A skill that runs on a schedule (daily, weekly, etc). Prefixed with `ritual-`
Action	A skill that runs on demand. No prefix
Internal skill	A sub-skill not user-facing. Prefixed with `_`

See Creating Custom Assistants for architecture details.

Term	Definition
Planning ritual	Prepares Captive notes from templates. Runs at start of period
Reflection ritual	Archives Captive notes to Periodic. Runs at end of period
Setup phase	First ritual phase: loads context, validates prerequisites
Core phase	Main ritual phase: interactive session, creates artifacts
Learning phase	Final ritual phase: records observations for self-learning
Template contract	Declaration of which template sections a ritual updates

See Creating Custom Rituals for implementation details.

Term	Definition
Engine	The 2bd system code. Git-tracked, lives in `~/Code/2bd-engine/`
Vault	Your personal notes and data. Cloud-synced, location configurable
Hub	Central navigation note marked with `✱` prefix. Examples: ✱ Home, ✱ Projects
Directive	Configuration file that personalizes Claude. Lives in `Systemic/Directives/`
Template	Starter structure for new notes. Lives in `Systemic/Templates/`

See Vault structure for complete reference.

Term	Definition
End-date prefix	Project naming using `YYYY-MM-DD-name.md` so deadlines sort first
FirstNameL	Person naming format: first name plus last initial. Example: `EstherS.md`
Period format	Date-based naming: `YYYY-MM-DD` (daily), `YYYY-Www` (weekly), `YYYY-QN` (quarterly)

See Naming conventions for complete rules.

Term	Definition
Observation	A recorded pattern from ritual execution. Stored in Synthetic
Cluster	Grouped observations with semantic similarity
Graduate	When a cluster reaches maturity and becomes an insight
Crystallize	Converting graduated observations into Semantic knowledge
Template evolution	Applying crystallized insights to improve templates
