// Pinned acceptance for P4.3 — `dist token create` / `list` / `revoke`
// over the persisted store (subplan 02 Slice 5).
//
// Drives the BUILT `build/dist` binary through the slice contract:
//
//   1. `token create` on a FRESH store (no database yet) → exit 0; the JSON
//      carries the raw secret (`dist_` + 64 hex) exactly once; dist.db
//      stores ONLY sha256(secret) — the secret's bytes appear nowhere under
//      the store — plus a `token.create` audit event.
//   2. A second token with `--scope read --expires-in 60` → expires_at is
//      created_at + 60.
//   3. `token list` → both tokens "active"; no secret in the output.
//   4. `token revoke` → exit 0; dist.db gains revoked_at + a `token.revoke`
//      audit event; list now shows "revoked".
//   5. Revoking an UNKNOWN id → exit 1 + `token.unknown`; revoking AGAIN →
//      exit 1 + `token.already_revoked`; both leave dist.db unchanged.
//   6. A publish into the same store still works (the model with tokens
//      round-trips through the publish pipeline's load/save).
//
// Store-side state is asserted by QUERYING `<store>/dist.db` through the
// SQLite bindings — independent of the db.sx load path under test.
