Enum VerbPresentationPolicy 

pub enum VerbPresentationPolicy {
    Standard,
    AlwaysVerbose,
    StreamAppendReceipt,
    StreamBatchReceipts,
}

Presentation override for a verb handler.

Most verbs use the default Standard policy which allows the caller’s requested PresentationMode to apply. A small set declare AlwaysVerbose because Agent-mode trimming (UUID shortening, empty-field dropping) would corrupt their response for downstream chaining — e.g. get returns UUIDs that callers pipe into link; shortening them here breaks the chain.

The policy is carried as a const in HandlerDef so the registry can consult it before applying the presentation transform.

Variants

Standard

Apply the caller’s requested PresentationMode unchanged.

AlwaysVerbose

Always use Verbose output regardless of the caller’s mode.

Declared verbs: get, link, query, traverse, neighbors, brain.feedback, brain.auto_feedback, memory.feedback, comm.delivered, git.digest, git.ingest_cursor.

link is included because the returned edge ID is the only handle for follow-up neighbors/traverse calls; short-form IDs risk prefix collision at scale (~65K edges can share an 8-char prefix).

brain.feedback is included because callers chain target_id from the response back into subsequent feedback or profile queries; an 8-char prefix is ambiguous and defeats the acknowledged-ID contract. memory.feedback has the same exact-target contract and rejects prefix resolution, so its acknowledged target_id must remain canonical. brain.auto_feedback acknowledges the same canonical target_id and feeds those strict paths, so it carries the same guarantee. comm.delivered is included because its id is an exact correlation key and the verb deliberately rejects prefix resolution (#1482).

git.digest is included because its successful response is also the durable receipt payload. Presentation must not shorten receipt_id or otherwise make the returned result differ from the stored result. git.ingest_cursor preserves raw checkpoint strings, full project UUIDs, and stored microsecond timestamps for persisted-position inspection.

StreamAppendReceipt

Preserve only the root append receipt’s created_at string in Agent mode.

StreamBatchReceipts

Preserve created_at and updated_at strings on immediate results array members in Agent mode.
