A verification bundle binds ten sub-claims. > Quote the Decision Receipt definition byte-identically or not at all: 'A Decision Receipt is a signed, replayable record of how a consequential decision was made, created at the moment it happens and independently verifiable afterwards.' > Tamper evidence is two checks together: a content edit leaves the Ed25519 signature valid (it covers the stored integrity hash) and is caught by the integrity check; rewriting the hash then fails the signature. Never claim the signature alone detects edits. # Read the authoring capability that governs this API key > Returns the authoring capability grant that currently governs the calling API key — the grant to name in `authoring_capability_id` — without its grantor signature, plus `root_capability_id`: the grant its chain starts at (equal to `id` unless the capability was carried to a successor draft by a supersession). Reachable only by a credential holding the `authoring:capability` scope and no `policies:read` / `policies:write`, whose capability grants `policy.read`. A broad key and a human session receive 403 FORBIDDEN; a capability that is missing, revoked or exhausted (anywhere in its chain), expired, not yet valid or fails integrity receives the gate's 403 AUTHORING_CAPABILITY_* code; a key holding `policies:read` or `policies:write` beside the carrier scope receives 403 AUTHORING_CAPABILITY_OBJECT_MISMATCH.
