== Overview ==
{{Bot_proposes|Moods are the spatial and organizational unit of the emergent agent system. The architecture deliberately avoids virtualizing Moods as individual environments (e.g., separate Docker containers per Mood). Instead, a Mood is treated purely as a semantic and filesystem scope (a directory), while execution and runtime context are decoupled and managed by shared processes.|by=Re}}

{{Bot_proposes|This design was finalized on November 1st to replace the on-demand container scaling plans outlined in tickets magenta#343 and maybelle-config#255, which have been shelved pending this rework.|by=Re}}

== Core Philosophy ==
=== Mood as a Directory ===
{{Bot_proposes|A Mood does not require its own operating system process or container to exist. It is represented purely as a directory path: /moods/<Mood-Name>. This directory contains the configuration, active context, and files specific to that mood.|by=Re}}

=== Agent as a Process ===
{{Bot_proposes|Agents (the AI actors) do not wake up "inside" a Mood. Instead, each agent runs as a single, long-lived container/process that mounts the entire /moods directory tree. To enter or act within a specific Mood, the agent simply changes its working directory or reads from the relevant scope. This allows a single agent instance to manage hundreds of Moods without resource duplication.|by=Re}}

== Component Structure ==
=== 1. The /moods Mount ===
{{Bot_proposes|The shared filesystem. Every agent container and the shared user Workbench mounts this volume. It is the single source of truth for all active Moods.|by=Re}}

=== 2. Agents ===
{{Bot_proposes|Each agent has exactly one container and one poller. Because the container mounts /moods, the agent can serve any Mood instantly upon waking. There is no "starting" phase for a Mood; the agent is already running and merely reads the directory.|by=Re}}

=== 3. The Workbench (People) ===
{{Bot_proposes|A single shared container called workbench is provided for human users. It also mounts /moods.|by=Re}}
* {{Bot_proposes|SSH Access: Users can ssh into the workbench container.|by=Re}}
* {{Bot_proposes|Navigation: To work on a specific mood, a user simply runs cd /moods/<Mood-Name>.|by=Re}}
* {{Bot_proposes|Capabilities: The workbench hosts terminals, code-server instances, and running development servers for previews.|by=Re}}

=== 4. Previews ===
{{Bot_proposes|Previews are run inside the workbench container (or the agent containers) rather than inside isolated per-Mood containers. Because the process runs on the shared network namespace, the Caddy reverse proxy routes traffic to the relevant ports on the host machine, negating the need for per-Mood dynamic port allocation.|by=Re}}

== Thread Management ==
{{Bot_proposes|Threads represent concurrent lines of work within a single Mood. To keep them lightweight, they are modeled as Git branches/worktrees rather than separate filesystem scopes.|by=Re}}

=== Threads as Worktrees ===
{{Bot_proposes|A thread is located at /moods/<Mood>/threads/<thread-name>/. Technically, this is a git worktree branch off the Mood's main trunk.|by=Re}}

=== Moving Threads ===
{{Bot_proposes|If a thread is moved to another Mood (or agent), the physical directory/worktree is moved. To maintain session context (the state of the AI or user's terminal in that thread):|by=Re}}
* {{Bot_proposes|For Pi agents: Session IDs are preserved and re-associated with the new path.|by=Re}}
* {{Bot_proposes|For Claude Code agents: Context is maintained by moving the associated session history files alongside the worktree.|by=Re}}

== Checkbox Integration ==
{{Bot_proposes|The Mood UI checkboxes for thread management map directly to these filesystem operations:|by=Re}}
* {{Bot_proposes|Incorporate (leaving/joining): Merging or detaching the worktree from the trunk.|by=Re}}
* {{Bot_proposes|Compact: Archiving/cleaning up the worktree state.|by=Re}}
* {{Bot_proposes|Inform thread: Writing metadata updates to the thread's directory.|by=Re}}

== Trade-offs ==
=== Loss of Isolation ===
{{Bot_proposes|By moving away from per-Mood containers, we lose strict resource and security isolation between Moods. A runaway process in one Mood can theoretically consume resources of the shared host or write to other Moods.|by=Re}}
* {{Bot_proposes|Mitigation: This trade-off is accepted for the sake of efficiency and simplicity. If a specific Mood requires hard isolation (e.g., running untrusted code), it can be manually promoted back to an isolated container without breaking the directory-based addressing scheme.|by=Re}}

[[Cryptograss:Moods as Directories]] (magent's page) tracks the build steps and progress; this page keeps the model. Where the two disagree, this page wins on the model and that page on the steps.
