# One edge, everything the log holds about it

`GET /v2/workspaces/{id}/warrants/{edge}`

## Request

- Base URL: `https://api.infolang.ai`
- URL: `https://api.infolang.ai/v2/workspaces/{id}/warrants/{edge}`
- Auth: one of:
  - HTTP bearer

The edge, its withdrawals, and whether the fold ignores it.

`label` and `inert` here are computed over THIS EDGE AND ITS BOTTOMS alone (`WarrantScope::Edge`). An undercut stated elsewhere is not in that set, so an edge labelled `in` here can be `out` in the workspace fold. Read the target's acceptance status for the authoritative answer; `label_scope` on the response says the same thing.

An edge is a REASON, with an exact id. Two edges whose prose resembles are two edges and no fold merges them; the fold never reads `reason` at all, which is why it is required — it is written for the human reading the audit, and nothing else will ever supply it.

There is NO delete. Withdrawing a reason is `bottom`, an APPEND that leaves the edge, its defeat, and the history of both in the log forever.

An acceptance status is a joint function of TWO logs — the warrant log and the assertion log the verdict oracle reads — so every read carries both cursors. Two answers are comparable only at equal pairs.

`contested` is in the status vocabulary and CANNOT OCCUR in the current topology: an edge attacks exactly one target, so undercut cycles are closed under their own targets and a support/rebut edge can never be undecided. Do not build a UI state for it.

Requires the `coord:read` scope. Accepts all three lanes: a session JWT (bounded by the caller's role on this workspace) or an `il_*` machine credential whose own scope set, workspace set and validity window cover it — both ceilings apply and neither can raise the other, so a credential carrying `coord:read` is still refused where the role does not permit it.

A credential with no scope record resolves to `LEGACY_DEFAULT`, which does NOT include `coord:read` — mint a key with it explicitly (`POST /v2/workspaces/{id}/keys`).

## Other responses

- `401`: Missing/invalid credential, or `credential_expired` — the credential is outside its `[not_before, expires_at)` window and must be replaced
- `403`: `insufficient_scope` — the credential's own scope set, or the caller's role on this workspace, does not cover the scope this route requires (the missing scope is named in the message). Or `forbidden` — the credential is not scoped to this workspace, or holds no grant on it
- `501`: The warrant verbs are not compiled into this deployment (`kernel-verbs` is off upstream)
