OpenMorph Specification v0.1.0

Status: Canonical — locked Feb 20, 2026. No schema changes without a version bump. Scope: This document defines the .morph/ directory format. It is the source of truth for all implementation work in OpenMorph (V1.0 Layer 3).

1. Concept

.morph/ is to AI augmentation what .git/ is to version control.

Drop a .morph/ directory into any folder and it becomes a Morph Space — an AI-augmented context with its own tasks, memory, conversations, skills, and canvas. The directory is:

• Human-readable — plain Markdown and YAML, editable with any text editor
• Portable — copy it to another machine, share it via git, check it into a repo
• Version-controlled — every write is a git commit; branch and time-travel as first-class operations
• Tool-agnostic — any tool that reads Markdown/YAML can integrate with .morph/
• Offline-first — git is local; the Morphee backend is a sync hub, not a dependency

Breaking change notice: V1.0 migrates ALL existing Spaces to .morph/ format. PostgreSQL becomes identity + read cache only. No backward compatibility with V0.9 data format.

└── README.md                          # Outside world — ACL-gated access

Directory naming conventions:

• core.* — built-in Morphee integrations. Registered and maintained by Morphee.ai.
• com.*, net.*, org.* — third-party integrations using reverse-domain notation.
• io.github.{user}.{name} — community / open-source extensions.
• Morphee.ai acts as the protocol authority for namespace registration (analogous to IANA).

The .morph/ root is the shared space. All integrations with root access (morph_root_access = True) can read root files (config.yaml, acl.yaml, canvas.yaml). Each integration is otherwise sandboxed to its own subdirectory.

The "outside world" is the parent folder of .morph/ (e.g. src/, README.md). Integrations may declare outside_world: true in their capabilities to request access. Access is governed by acl.yaml and not yet enforced (V1.2+).

manifest.yaml is required in every integration directory. Written automatically on first write via BaseInterface.morph_write(). Declares identity, version, and capabilities.

Rules:

• .morph/config.yaml is the only truly required file — its presence defines a Space.
• Integration directories are created on first write (not upfront).
• Files use UUID-based names for system entities and slug-based names for user-defined entities.
• No binary files. Ever.

---

2.1 Integration Communication Protocol

Every integration communicates via three channels. All three are declared in BaseInterface:

Channel	Direction	API	Nature
Action	Morphee → Integration	execute()	Synchronous request/response
File	Integration ↔ .morph/	morph_write() / morph_read()	Async, persistent, git-tracked
Event	Integration → EventBus → subscribers	emit + subscribe()	Async, real-time, ephemeral

Event catalog — published_events

Each integration declares a static list of events it can emit as a class attribute:

class CalendarIntegration(BaseInterface):
    morph_directory = "com.google.calendar"

    published_events = [
        EventDefinition(
            name="com.google.calendar.event_created",
            description="A calendar event was created",
            payload_schema={"event_id": "str", "title": "str", "start": "datetime"},
        ),
        EventDefinition(
            name="com.google.calendar.event_upcoming",
            description="A calendar event starts within the next 15 minutes",
            payload_schema={"event_id": "str", "minutes_until": "int"},
        ),
    ]

published_events is schema metadata — readable by any tool, the InterfaceManager, and future WASM sandboxing to know what an integration emits without running it.

Event names follow the integration namespace: {morph_directory}.{event_slug}.

Subscriptions — subscribe()

Integrations that react to other integrations' events register handlers in setup():

class TaskIntegration(BaseInterface):
    morph_directory = "core.tasks"

    async def setup(self):
        # Auto-create a task when a calendar event is created
        await self.subscribe("com.google.calendar.event_created", self.on_calendar_event)

    async def on_calendar_event(self, payload: dict) -> None:
        # payload matches the publisher's payload_schema
        ...

subscribe() registers with the global EventBus (Redis pub/sub). Pattern matching is supported: "core.tasks.*" receives all task events.

V1.2 — Declarative cross-wiring via acl.yaml

In V1.2, subscriptions can also be declared in .morph/acl.yaml without code changes. Users and AI can wire integrations together at the Space level:

# .morph/acl.yaml (V1.2+)
subscriptions:
  - from: com.google.calendar
    event: event_created
    to: core.tasks
    handler: create_task_from_event

This makes integration composition a configuration concern, not a code concern — and enables the WASM extension marketplace to offer pre-built wiring templates.

3. File Schemas

3.1 config.yaml (REQUIRED)

The presence of this file declares a Morph Space.

# OpenMorph spec version — MUST be present and valid
openmorph_version: "0.1.0"

# Space identity
space:
  id: "550e8400-e29b-41d4-a716-446655440000"   # UUID, backend-generated
  name: "TechCorp API Project"
  type: "project"   # project | personal | team | family | classroom
  created_at: "2026-02-20T10:00:00Z"
  created_by: "alice@example.com"               # Identity hint, not enforced

# Parent space for nested spaces (omit if root)
parent:
  path: "../.morph"         # Relative path to parent .morph dir
  inherit_acl: true         # Whether to inherit parent ACL rules
  inherit_integrations: true  # Whether to inherit parent integrations

# Link to Morphee backend identity (omit for fully local/offline spaces)
group:
  id: "123e4567-e89b-12d3-a456-426614174000"   # Group UUID
  name: "TechCorp Engineering"
  sync_url: "https://api.morphee.app/sync/123e4567-e89b-12d3-a456-426614174000"

# Git configuration
git:
  enabled: true
  remote_url: "git@github.com:techcorp/api-project.git"   # null if local-only
  branch: "main"
  auto_commit: true    # Commit on every write
  auto_push: false     # Push only on explicit sync

# Sync mode (see §5)
sync:
  mode: "morphee-hosted"   # local-only | morphee-hosted | git-remote
  encryption: "group-key"  # group-key | user-key | none

# Active integrations (determines which tools the AI can use in this Space)
integrations:
  - llm
  - memory
  - tasks
  - google-calendar
  - gmail
  # skills and schedules are implicitly enabled when their dirs exist

Field constraints:

• openmorph_version — must be a valid semver string matching a known spec version. Readers MUST reject unknown major versions.
• space.type — must be one of: project, personal, team, family, classroom.
• sync.mode — must be one of: local-only, morphee-hosted, git-remote.
• parent.path — must be a relative path, not absolute. Circular references are invalid.

---

3.2 acl.yaml (OPTIONAL)

Access control rules for this Space. If absent, the parent Space's ACL applies. If no parent, the group's default ACL applies.

openmorph_version: "0.1.0"

# Space owner — full access always
owner: "550e8400-e29b-41d4-a716-446655440001"

# Explicit member rules (augments group membership)
members:
  - user_id: "550e8400-e29b-41d4-a716-446655440002"
    role: "editor"       # viewer | editor | admin
    granted_by: "550e8400-e29b-41d4-a716-446655440001"
    granted_at: "2026-02-20T10:00:00Z"
    expires_at: null     # null = permanent

# Resource-level overrides
permissions:
  tasks:
    create: ["editor", "admin"]
    read: ["viewer", "editor", "admin"]
    update: ["editor", "admin"]
    delete: ["admin"]
  conversations:
    create: ["viewer", "editor", "admin"]   # anyone can chat
    read: ["viewer", "editor", "admin"]
    delete: ["admin"]
  memory:
    create: ["editor", "admin"]
    read: ["viewer", "editor", "admin"]
    delete: ["admin"]
  skills:
    create: ["admin"]
    execute: ["editor", "admin"]
  files:
    read: ["viewer", "editor", "admin"]
    write: ["editor", "admin"]

---

3.3 canvas.yaml (REQUIRED)

Stores the spatial canvas layout. Persists card positions and minimized state across sessions. This is what canvas.yaml in .morph/ replaces the current localStorage store.

openmorph_version: "0.1.0"

# Schema version for canvas layout (independent of openmorph_version)
canvas_version: 1

updated_at: "2026-02-20T10:00:00Z"

# Active component cards (currently rendered on canvas)
# Note: component IDs are ephemeral per AI render session.
# In V1.0, persistent cards have stable IDs (e.g. pinned task views).
cards: []

# Persisted layout preferences (stable across renders)
layout:
  # Default grid slots that auto-placement uses (% of canvas dimensions)
  grid_columns: 3
  grid_row_height_pct: 42.0

  # Named pinned views that always appear on the canvas
  # These are stable V1.0 feature — not ephemeral AI renders
  pinned_views: []
    # Example:
    # - id: "pinned-tasks-view"
    #   type: "task_list"
    #   position: { x: 2.0, y: 2.0 }
    #   config: { filter: "status:pending" }
    #   minimized: false

# Background style
background:
  style: "dots"   # dots | grid | none
  opacity: 0.05

Note on ephemeral vs persistent cards:

In V0.9, all canvas cards are ephemeral (created by the AI per conversation, lost on reload). In V1.0:

• Ephemeral cards (AI renders) — not stored in canvas.yaml, managed by localStorage/in-memory as today
• Persistent cards (pinned_views) — stable, defined in canvas.yaml, appear every time the Space is opened

The canvas.yaml format is designed to accommodate both. Implementation of pinned_views is deferred to V1.1.

3.4 tasks/task-{id}.md

One file per task. Filename is task-{uuid}.md. YAML frontmatter carries machine-readable state; Markdown body carries human-readable notes.

## Notes

Add to Google Calendar. Alice mentioned she prefers 9-11am slots.

Valid type values: message | webhook | cron | skill_execution | approval_request | subtask

Valid status values: pending | running | blocked | paused | completed | failed | cancelled

State machine:

pending  →  running    (task starts executing)
pending  →  cancelled  (user cancels before start)
pending  →  paused     (user pauses)
running  →  blocked    (waiting for approval or external event)
running  →  paused     (user pauses)
running  →  completed  (success)
running  →  failed     (unrecoverable error)
blocked  →  running    (approval granted / event resolved)
blocked  →  cancelled
paused   →  running    (user resumes)
paused   →  cancelled
failed   →  pending    (retry — increments retry_count)
failed   →  cancelled

completed and cancelled are terminal states — no transitions out.

Constraints:

• priority must be 0–3.
• retry_count must not exceed max_retries — the backend enforces this before writing.
• id in frontmatter must match the filename UUID. Readers should validate this.

## user | 2026-02-20T10:00:00Z

Can you add a dentist appointment for Alice on Thursday?

## assistant | 2026-02-20T10:00:03Z

I'll add that to the calendar now. What time works best for Alice?

## user | 2026-02-20T10:00:45Z

9am please.

## assistant | 2026-02-20T10:00:48Z

Done — I've added "Alice: Dentist" on Thursday at 9am to the calendar.

Message format in body:

Each message is a level-2 heading with the pattern ## {role} | {iso_timestamp} followed by the message content.

• role is user or assistant
• iso_timestamp is UTC ISO 8601
• Tool calls and component renders are NOT stored inline — they are referenced by ID in metadata.tool_call_ids if needed

Constraints:

• message_count in frontmatter must equal the actual count of ## headings in the body. The backend validates this on read.
• Message content is stored verbatim (no truncation). Long conversations may result in large files — this is acceptable.

3.9 vault.enc

An encrypted key-value store for credentials and secrets. Never stored in plaintext.

ENC:gAAAAABh... (Fernet-encrypted blob)

The decrypted content is YAML:

# Credentials for integrations configured in this Space
google_oauth_access_token: "ya29.a0..."
google_oauth_refresh_token: "1//0..."
google_oauth_expires_at: "2026-02-20T11:00:00Z"

Rules:

• The entire file is a single Fernet-encrypted blob with an ENC: prefix.
• The encryption key is derived from the group's key (group-key mode) or the user's key (user-key mode).
• The backend's EncryptionService handles all vault reads/writes.
• The file must never be committed to a public git remote. The backend must validate sync.mode != "git-remote" before writing credentials to vault.enc. For git-remote sync, credentials must live in the OS keychain (Tauri) or backend secrets store.
• vault.enc is excluded from diffs and patches.

4. Git Conventions

Every write to .morph/ is a git commit. Commit message format:

morph({type}): {short description}

{optional body}

Commit types:

Type	When
morph(task)	Task created, updated, status changed
morph(skill)	Skill created or updated
morph(schedule)	Schedule created or updated
morph(memory)	Memory entry stored or deleted
morph(conversation)	Conversation updated (new messages)
morph(canvas)	Canvas layout changed
morph(config)	Space configuration changed
morph(acl)	ACL rules changed
morph(migrate)	Data migration (automated)
morph(sync)	Pull/merge from remote

Examples:

morph(task): create task "Add dentist appointment"

morph(task): complete task 550e8400 — "Add dentist appointment"

morph(memory): store preference — Alice prefers morning appointments

morph(conversation): update conv 550e8400 — 2 new messages

morph(skill): create skill "daily-briefing"

morph(canvas): update canvas layout — card moved top-left

morph(migrate): V0.9 → V1.0 migration — 47 tasks, 12 conversations

Author: All automated commits use:

Author: Morphee <morphee@local>

Human commits (user edits .morph/ files directly) preserve the user's git identity.

Branch naming:

Branch	Purpose
main	Production state of the Space
experimental/{name}	AI-created experimental branches
sync/{timestamp}	Temporary branch for conflict resolution

---

5. Sync Modes

Configured in config.yaml under sync.mode.

local-only

The Space lives entirely on the local device. No network sync.

• Git is optional but encouraged for local history
• git.remote_url must be null
• Credentials in vault use OS keychain (Tauri) — no backend needed
• Web client: not supported (web has no local filesystem)

morphee-hosted

The Space syncs to Morphee's backend and a Morphee-managed GitLab repo.

• group.sync_url points to the backend sync endpoint
• The backend maintains a GitLab repo per Space
• Sync happens: on explicit user request, on app foreground, or on timer
• Pull = git fetch origin && git merge origin/main --ff-only
• Push = git push origin main
• Conflicts: detected by non-fast-forward push → sync/{timestamp} branch created → user resolves

git-remote

The Space syncs to a user-provided git remote (GitHub, GitLab, Gitea, etc.).

• git.remote_url points to the user's repo
• No Morphee backend involvement for sync
• The user is responsible for authentication (SSH keys, tokens)
• Credentials must NOT be in vault.enc (would be committed to the user's repo)
• Same pull/push/conflict flow as morphee-hosted

Sync algorithm

1. Pull remote (if not local-only):
   - git fetch origin
   - If local is behind: git merge origin/main --ff-only
   - If diverged: create sync/{timestamp} branch, notify user

2. Write local change:
   - Write file(s) to .morph/
   - git add {changed files}
   - git commit -m "morph({type}): {description}"

3. Push (if not local-only and auto_push=true):
   - git push origin main
   - On failure: queue for next sync

Conflict resolution (V1.0): Last-write-wins for non-overlapping fields. If the same task file was modified in two branches simultaneously, the backend presents both versions to the AI + user for manual merge. AI-mediated merge UI is V1.1.

---

6. Nested Spaces

A Space can contain sub-Spaces. Each sub-Space has its own .morph/ directory inside the parent:

project/
├── .morph/               # Root Space (TechCorp API Project)
│   └── config.yaml
├── frontend/
│   ├── .morph/           # Sub-Space (Frontend Team)
│   │   └── config.yaml   # parent.path: "../../.morph"
│   └── src/
└── backend/
    ├── .morph/           # Sub-Space (Backend Team)
    │   └── config.yaml   # parent.path: "../../.morph"
    └── api/

Inheritance rules:

Resource	Inherited by default	Override
ACL	Yes (if inherit_acl: true)	Define acl.yaml in sub-Space
Integrations	Yes (if inherit_integrations: true)	Add/remove in sub-Space config.yaml
Memory	No — sub-Space has its own memory	Use scope: "group" for cross-Space memory
Tasks	No — sub-Space has its own tasks	N/A
Skills	Yes — parent skills available	Sub-Space can shadow with same-named skill
Canvas	No — each Space has its own canvas	N/A

Circular nesting is invalid. Implementations must detect and reject it.

Maximum nesting depth: 10 levels. Deeper hierarchies must be rejected with a clear error.

7. Migration Guide (V0.9 → V1.0)

This is a breaking change. The migration script runs once on first V1.0 deploy.

What changes

V0.9	V1.0
Tasks in PostgreSQL tasks table	Tasks in .morph/tasks/task-{id}.md + PostgreSQL read cache
Skills in PostgreSQL skills table	Skills in .morph/skills/{name}.yaml + read cache
Schedules in PostgreSQL schedules table	Schedules in .morph/schedules/{name}.yaml + read cache
Memory in PostgreSQL memory_vectors	Memory files in .morph/memory/{type}/{id}.md + pgvector read cache
Conversations in PostgreSQL conversations + messages	Conversations in .morph/conversations/conv-{id}.md + PostgreSQL read cache
Canvas positions in localStorage	Canvas layout in .morph/canvas.yaml + localStorage as L1 cache
Spaces as database rows	Spaces as .morph/ directories (database row becomes pointer)

Migration script behavior

1. For each existing Space (PostgreSQL):
   a. Create .morph/ directory at backend storage path
   b. Write config.yaml from Space metadata
   c. Write acl.yaml from ACL rules (if any)
   d. Write canvas.yaml (empty state)
   e. git init + initial commit "morph(migrate): V0.9 → V1.0 migration"

2. For each Task in the Space:
   a. Write .morph/tasks/task-{id}.md
   b. Commit: "morph(migrate): import task {id}"

3. For each Skill:
   a. Write .morph/skills/{name}.yaml
   b. Commit: "morph(migrate): import skill {name}"

4. For each Schedule:
   a. Write .morph/schedules/{name}.yaml
   b. Commit: "morph(migrate): import schedule {name}"

5. For each Conversation + Messages:
   a. Write .morph/conversations/conv-{id}.md
   b. Commit: "morph(migrate): import conversation {id}"

6. For each Memory entry:
   a. Write .morph/memory/{type}/{id}.md
   b. Commit: "morph(migrate): import {count} memories"

7. Update PostgreSQL:
   a. Mark all Spaces as migrated (add migrated_at column)
   b. PostgreSQL data is NOT deleted — it becomes the read cache
   c. All subsequent writes go to Git first, then update PostgreSQL

8. Verify:
   a. Read back all migrated entities from .morph/ files
   b. Compare checksums against PostgreSQL data
   c. Log migration report

Rollback: If migration fails partway, the script can be re-run idempotently (it skips already-migrated entities). PostgreSQL data is never deleted during migration.

Timeline

Migration runs automatically on first V1.0 backend startup. Expected duration: ~2 minutes for a typical group with 1000 tasks / 500 conversations / 100 skills.

8. Versioning Policy

The spec follows semver:

• Patch (0.1.x) — Clarifications, fixing spec bugs, adding optional fields. Fully backward compatible.
• Minor (0.x.0) — New optional top-level sections, new optional fields. Backward compatible.
• Major (x.0.0) — Breaking changes to required fields, renamed sections, removed fields. Migration required.

Reader behavior:

• Readers MUST understand the major version in openmorph_version.
• Readers MAY ignore unknown optional fields (forward compatibility).
• Readers MUST reject files with a higher major version than they understand.

Current version: 0.1.0

Next planned version: 0.2.0 — adds pinned_views in canvas.yaml (V1.1 persistent canvas cards)

9. Open Questions

These are the only design decisions NOT yet locked. They will be resolved before implementing the relevant phase.

#	Question	Context	Target Phase
Q1	Conflict resolution UX — Last-write-wins, manual diff UI, or AI-mediated?	V1.0 uses last-write-wins. AI-mediated merge is the goal.	V1.1
Q2	vault.enc in git-remote mode — How do users manage credentials when Morphee backend isn't involved?	Options: OS keychain only, .env file at project root (gitignored), or user-managed secret manager	V1.0 Phase 2
Q3	Performance ceiling — At what .morph/ size does git operations slow down?	Need to benchmark git log, grep, status at 10k / 50k / 100k files	V1.0 Phase 1
Q4	Pinned views schema — Exact format for stable canvas cards in canvas.yaml	See §3.3 pinned_views placeholder	V1.1
Q5	Sub-Space discovery — Should morph_discover scan recursively or only top-level?	Recursive could be slow on large repos; top-level misses nested spaces	V1.0 Phase 2

---

Written Feb 20, 2026. Locked for OpenMorph V1.0 implementation. Next review: when Q1–Q5 are resolved or when a schema change is needed.
