`mayros dag`

The mayros dag command provides access to the Semantic DAG — the immutable, Ed25519-signed audit trail that records every action in Mayros.

Global Options

Flag	Description	Default
`--cortex-host <host>`	Cortex host	`127.0.0.1` (or from config)
`--cortex-port <port>`	Cortex port	`19090` (or from config)
`--cortex-token <token>`	Cortex auth token (or `CORTEX_AUTH_TOKEN` env var)	—

Subcommands

`dag tips`

Show current DAG tip hashes (the frontier of the DAG — latest actions with no children).

bash
mayros dag tips

`dag action <hash>`

Inspect a specific DAG action by its content-addressable hash. Shows author, sequence number, timestamp, payload type, summary, parents, and signature status.

bash
mayros dag action abc123def456

`dag history <subject>`

Show the action history for a specific subject (e.g. a venture, mission, or agent).

bash
mayros dag history "venture:security-audit"
mayros dag history "venture:security-audit" --limit 50

Flag	Description	Default
`--limit <n>`	Maximum actions to return	`20`

`dag chain <author>`

Show the action chain for a specific author/node. Useful for auditing everything a particular node has done.

bash
mayros dag chain node-001
mayros dag chain node-001 --limit 50

Flag	Description	Default
`--limit <n>`	Maximum actions to return	`20`

`dag stats`

Show DAG statistics: total action count and tip count.

bash
mayros dag stats

`dag prune`

Prune old DAG actions with configurable retention policies. Prompts for confirmation unless --yes is passed.

bash
mayros dag prune --policy keep_last --value 1000 --checkpoint
mayros dag prune --policy keep_since --value 1710000000 --yes

Flag	Description	Required
`--policy <policy>`	Retention policy: `keep_all`, `keep_since`, `keep_last`, `keep_depth`	Yes
`--value <n>`	Policy value (timestamp, count, or depth)	No
`--checkpoint`	Create a checkpoint before pruning	No
`--yes`	Skip confirmation prompt	No

`dag at <hash>`

Time-travel to a specific action hash. Reconstructs the knowledge graph state as it existed at that point by replaying actions from genesis.

bash
mayros dag at abc123def456

`dag diff <from> <to>`

Show the diff between two DAG action hashes — lists all actions that occurred between the two points.

bash
mayros dag diff abc123 def456

`dag export`

Export the full DAG as a visual graph in DOT, Mermaid, or JSON format.

bash
mayros dag export
mayros dag export --format dot
mayros dag export --format json

Flag	Description	Default
`--format <format>`	Export format: `dot`, `mermaid`, `json`	`mermaid`

`dag verify <hash>`

Verify the Ed25519 signature of a specific DAG action. Confirms whether the action was signed by the claimed author.

bash
mayros dag verify abc123def456 --public-key <hex-or-base64>

Flag	Description	Required
`--public-key <key>`	Ed25519 public key (hex or base64)	Yes
