## `orient`

Load workspace + task context first. Actions: `start` (session opener), `task` (mid-session refresh), `record-activation`.

## `entries`

Actions: `list`, `get`, `batch`, `search`, `update`, `commit`, `history`, `move`, `verify`. Optional filters: `collection`, `status`, `label`, `tag`, `query`.

* `entries action=update` — patch an entry (writes need session + scope).
* `entries action=move` — move `entryId` to `toCollection` slug.
* `entries action=commit` — promote a draft with validation — **human confirms** in consensus workspaces.
* `entries action=history` — audit trail for an entry.
* `entries action=verify` — mark an entry verified (lightweight, no codebase scan).

## `capture`

Create entries — single (`name`, `description`, optional `data`) or batch (`action=batch`, `items[]`).

## `relations`

Create or manage typed edges. Actions: `create`, `batch-create`, `dismiss`, `delete`, `find`, `suggest`.

## `quality`

Score, audit, or verify. Actions: `check`, `re-evaluate`, `verify-chain` (glossary code-mapping consistency check), `audit`.
