Function: isPlcDid()

isPlcDid(did): boolean

Defined in: src/types/atproto-validators.ts:98

Reports whether a string is a well-formed did:plc: identifier.

Parameters

did

string

Candidate DID string

Returns

boolean

True when the value is did:plc: followed by 24 base32-sortable characters

Remarks

PLC identifiers are exactly 24 characters drawn from the base32-sortable alphabet (a–z, 2–7). toDID deliberately does not enforce this: it accepts any syntactically plausible DID across every method, and hundreds of test fixtures rely on short readable placeholders.

This stricter check exists for values that must be a real PLC identity rather than a plausible-looking string — configuration in particular. The governance PDS DID was configured as did:plc:chive-governance in every environment file, which is not a PLC identifier at all; nothing rejected it, and the governance sync resolved nothing for as long as it was set.
